9.2 Fundoplication and Partial Fundoplication Techniques
intact peristalsis manometry: Nissen procedure
impaired peristalsis allows only limited mechanical augmentation of LES: partial Toupet fundoplication
Fig. 9.2.3 Prevention of persistent postoperative dysphagia by using in selective cases a partial fundoplication (Toupet) when esophageal clearance is reduced by impaired esophageal peristalsis.
Contraindications:
− Extensive cardiopulmonary and other anesthesia risk fac­tors.
− Disorders of blood coagulation.
− Previous operations in the upper abdomen can be a contrain­dication to the laparoscopic approach of fundoplication. However, if the patient is preoperatively well informed, ex­ploratory laparoscopy prior to laparotomy can be advised to assess the possibility of laparoscopic adhesiolysis followed by laparoscopic fundoplication or early conversion.
Operative Risk and Informed Consent
Prior to operation the patient must be informed about the cause of the disease and the possible corrections that can be achieved by the operation. All patients must be informed of the possi­bility of conversion to conventional laparotomy. Factors that can make a conversion likely are:
− Short esophagus after decades of reflux history and impossi­bility to mobilize the distal part of the esophagus into the ab­domen to position the fundoplication correctly.
− Confluent active esophagitis or a history of stricture with ex­tensive periesophageal tissue reaction in the lower medi­astinum;

Preoperative Preparation
− Foley catheter (optional).
− Nasogastric tube (optional).
− General anaesthesia: intubation and monitoring required due to elevated in­traabdominal pressure, CO
− Positioning.
In general, there are two possibilities for the organization of the operating team. The patient can be positioned with his legs close together on the operating table and the surgeon and his assistant standing on each side of the patient, or the patient is positioned with the legs spread apart, which allows the operat­ing surgeon to stand between the legs (Fig. 9.2.6).

Method of Access (Fig. 9.2.7)
Laparoscopic fundoplication techniques can be performed as any other operation at the esophageal hiatus, usually using 5 trocars, because there is a need for 1 camera trocar, 2 trocars for helping to expose the target area (liver retractor, pull-down of stomach and gastrosplenic ligament), and 2 trocars for pick­up and dissection instruments. The camera trocar can be inserted along the midline, often a third to half way distance between the umbilicus and the xi­phoid. The trocar for the liver retractor is inserted in the right upper quadrant at the subcostal margin. The retractor and grasper for the gastrosplenic ligament is brought in at the re­spective side of the left subcostal margin. The retractor for the right hand dissection instrument is brought in between the midline and the left retractor trocar. It is important to make sure that this trocar has enough room to turn and be manipulated, as this is necessary during the operation. The position of the left hand dissection trocar must be chosen very carefully. It depends on the size and position of the falciform ligament. The position must allow, on one hand, an easy gliding of the instrument to the hiatus without hindrance by the falciform ligament, on the other hand, it must also be far enough from the camera trocar, so that it can be manipulated without “dueling” with the la­paroscope and camera.

the legs, the legs must be positioned close together on the table or ab­duced, respectively.

Fig. 9.2.8 Dissection of the gastroesophageal junction. Incision of the peritoneum near the hiatus under careful preservation of the vagal he­patic branches and identification of the right crus and the hiatal arch. Usu-
ally the grasper will lift up the peritoneum and with scissors, using ultra­sonic technique or cautery for hemostasis the dissection can be carried out. Creation of the “gastroesophageal window”: Once the right crus is iden­tified, the aim of the dissection may not be the esophagus or the gastroe­sophageal junction, but the crus and the lower mediastinum. It is much easier to dissect and later identify the distal esophagus in the lower medi­astinum than right at the gastroesophageal junction due to the adher­ence of the esophageal fat pad and the tissue along the lesser curvature of the stomach. While a grasper is pushing the right crus to the right, the surgeon can rather easily either with the scissors or with the swab push the loose tissue between the right crus and the esophagus from each other. As a consequence, the intraabdominal gas will help to develop a dissection layer in the lower mediastinum. With a disserting swab, now, the distal esophagus can be easily pushed aside in the lower medi­astinum.
Special Techniques
The Nissen Fundoplication Technique
Step-by-Step Procedure
I Technical preparation
1. Control of patient’s correct positioning.
2. Selection of ultrasonic or high frequency electrocautery instru­ment, correct choice of power level in relation to patient’s size.
3. Sterile preparation of the abdomen, connection of all instru­ments to respective sources or terminals.
II Establishment of the pneumoperitoneum
1. Skin incision at the midline and insertion of the Veress needle.
2. Safety steps with injection, aspiration as well as manometric tests, insufflation procedurewith lowand highflow after adjust­ment of pressure level (children under 14: 6−8 mm Hg, adoles­cents and adults: 10−14 mm Hg). In patients with cardiopulmo­nary risk factors or small children gas flow only with 1−2 l/min.
3. Alternative: local open approach.
Fig. 9.2.9 Nissen fundoplication, fundus mobilization. The left retractor is used to bring tension on the gastrosplenic ligament, while the right re­tractor is pulling the stomach towardsthe right. This allows a good view of the gently stretched short gastric vessels. In the avascular space between the vessels the tissue is divided. The vessels are transected between clips or with the harmonic scalpel. This dissection is carried on along the fundic curvature. Special care must be taken not to injure the spleen.
A similar approach is advised by using the grasper to lift up the hiatal arch and gently push a swab right under the hiatal arch into the lower medias­tinum. With gentle force, the esophagus can be pushed downwards thus freeing the loose tissue connections between the pericardium and the dis­tal esophagus. When this maneuver is repeated at the left crus, the distal esophagus is almost fully mobilized. Completed “gastroesophageal window”. This is a view through the “gastroesophageal window” showing the anatomic landmarks that must be dissected completely before starting with the sutures. This shows the hiatal crura, the hiatal arch, the distal esophagus, the high pressure zone, the vagal trunks, and the subphrenic area on the left with the upper pole of the spleen.
III Laparoscopy
st
1. Insertion of the 1
trocar with special caution, e. g., according to experience insertion of “Kegel” trocar under constant rota­tion, rather than down force pressure through the peritoneum
(caution: no guarantee for protection from damage).
2. Insertion of camera and review of intraabdominal organs and special circumstances.
3. Insertion of all other trocars under visual control; inspection of the upper abdominalareaand hiatalregion togetthe “feeling” and an impression of the situs and the tissue quality before starting with the dissection.
4. Exploration of the hiatal hernia to assess its size and compare findings with the preoperative endoluminal endoscopy report and esophageal function measurements. Pull on the stomach caudally to reposition the hernia and to assess the mobility of the distal esophagus. An inability to reduce the stomach and the cardia into the abdomen can be an early sign that the esophagus istoo shortand anearly conversion or evenprimary thoracic approach is necessary.
5. Incision of the phrenoesophageal membrane with careful pre­servation of the hepatic vagal branches.
252
Fig. 9.2.10 Posterior crural closure or hiatoplasty. If necessary, and that is the case in most reflux patients, the hiatus should be decreased in size by closing posteriorly both crural pillars. After establishing the gastroe-
sophageal window, a loop can be placed around the gastroesophageal junction to pull the latter in any direction. To have the exposure of the area dorsal to the esophagus, the gastroesophageal junction is pulled to the
left, which allows to look from the right to both crura. A nonresorbable su-
ture (2−0 or 0) is brought in and, usually, 2 oreven 3 sutures are necessary
to close the hiatus to the appropriate size. It is very important to checkthe hiatal size after closing it posteriorly.This can be done byputting a grasper into the hiatus next to the esophagus. A 10-mm instrument should easily be able to pass into the mediastinum next to the esophagus.
9.2 Fundoplication and Partial Fundoplication Techniques
Partial Fundoplication Techniques
The dissection of the gastroesophageal junction should be the same, regardless of what kind of final fundoplication or partial fundoplication technique is used. The popularity for one or the other fundoplication depends often on the surgical school or country. For example, the Toupet partial fundoplication is very popular in French speaking countries. The most popular partial fundoplication in open operation is the Belsey Mark IV repair which is, in the original version, always performed through a left thoracotomy. Only very few authors have performed so far a thoracoscopic Belsey Mark IV repair. Other partial fundoplica­tion techniques have all been performed laparoscopically in the past few years.
Laparoscopic Hill Procedure (Fig. 9.2.14)
The dissection of the gastroesophageal junction at the hiatus as well as of the crura is similar in all procedures. For the laparo­scopic Hill procedure a more extensive dissection of the tissue connections of the posterior gastric wall and the lesser curvature is necessary to clearly identify the arcuate ligament, ventrally, to the aorta. This can be achieved by directing the dissection from the right crus further caudally towards the celiac trunk, until the anterior and posterior “gastric bundle” is identified. The latter is the perigastric tissue that attaches the proximal stomach towards the retroperitoneum. This tissue bundle carrying small vessels, fat, peritoneal layer and the vagus branches is grasped and then sutured to the arcuate ligament and hiatal crura which are also closed as described previously.By this technique, the ga­stric fundus is also pulled around the distal esophageal area, thus mechanically augmenting the sphincter area.
6. Identification of the right hiatal crus and further, by continu­ing the dissection towards the left, identification of the ante­rior hiatal arch (Fig. 9.2.8).
7. Separating the right crus from the esophagus by advancing
with a swab, grasper or scissors into the lower mediastinum; very important: crucial landmark of dissection is not the esophageal wall, but the right crus and the hiatal arch as well as, later in the dissection, the left crus to find the correct dis­section layer to reach the low mediastinum. If one tries to use the esophageal wall as a landmark for the dissection way around the esophagus, a false passage can mean immediate
laceration of the esophageal wall. Therefore it is very impor-
tant to first identify and dissect the right crus, the hiatal arch and the left crus. Once these landmarks are identified, the
proximal stomach and the distal esophagus will automatically
emerge as mobile structures even in adipose patients with a
large esophageal fat pad.
8. Identification of the vagal trunks and branches in the distal
esophagus.
9. Dissection and creation of the so-called “gastroesophageal
window” deep to the posterior esophageal wall, which allows four important steps:
1. view of the left side to the upper pole of the spleen and the
left crus,
2. exposure of both crura to perform a posterior hiatal clo-
sure,
3. safe looping of the lower esophagus (Fig. 9.2.10),
4. a safe pull-through of the mobilized fundus (Fig. 9.2.11 +
12).
10. Mobilization of the gastric fundus and greater curvature by dividing the short gastric vessels: This can be achieved by single or double clipping of both the gastric and splenic sides of the vessels, by the use of laparoscopic stapling devices or
harmonic scalpel or by bipolar coagulation (cave: thermal in-
jury of the greater curvature and gastric wall necrosis)
(Fig. 9.2.9).
11. Dissection of the left hiatal crus.
12. Division of posterior gastric artery usually coming from the splenic artery in patients in whom this vessel limits the mobil-
ity of the posterior wall of the gastric fundus.
13. Partial closure of the hiatus posteriorly by approximating the
left and right crus using non resorbable sutures (0-metric) (Fig. 9.2.10).
14. Transoral introduction of a 45−60 French bougie for calibra­tion to have a minimum diameter around which a wrap is su­tured. Once the bougie is in place in the gastric lumen, a post­erior and anterior fundic flap should be pulled around the lo­cation of the distal esophageal sphincter without any tension. The pulled-through posterior flap to the right side should stay
in that position when the grasper is removed. The latter is a
good sign for a tensionfree pull-through.
15. The final stage of the Nissen fundoplication is performed with the bougie in place using 1−3 stitches with non-absorbable suture material to complete a floppy and short wrap
(Fig. 9.2.3). The looseness of the wrap should be checked
after the suture is finished by introducing a grasper comfort­ably between wrap and esophagus containing the bougie.
16. Removal of the trocars, if possible under visual control.

to have a symmetric wrap around the lower esophageal sphincter. The gastroesophageal junction is pulled ventrally and the grasper will pull the flap of the fundus dorsally and from the left to the right side. There, the flap is advanced further and picked up by a second grasper for the pull-
Laparoscopic Toupet Procedure (Fig. 9.2.3)
For the laparoscopic Toupet procedure, dissection of the
gastroesophageal junction, the hiatal crura as well as the proxi­mal fundus is necessary as described above. The fundic flap is pulled through the gastroesophageal window from the left to
the right side. Then the fundus is fixed to the right diaphrag­matic crus with 2−3 sutures. In addition, the fundus is then su-
tured to the distal esophagus, again 3 sutures on the right side
of the esophagus and 3 sutures on the left side of the esophagus.
Care is taken not to damage the vagal trunks.
Anterior 180° Hemifundoplication (Fig. 9.2.15)
Several procedures of anterior partial fundoplication are known, such as the Dor fundoplication, Lind fundoplication and
Watson fundoplication. The Dor technique is usually used for
coverage of a myotomy for achalasia at the anterior aspect of the
distal esophagus and proximal stomach. In the Watson tech­nique the fundus is attached over a few centimeters to the left
anterior aspect of the distal esophagus covering approximately
90° of the circumference. Depending on the author, these partial
anterior fundoplications cover between 90 and 180° of the ante­rior aspect of the esophagus. In patients with reflux disease and
an impaired esophageal peristalsis an anterior 180° hemifundo­plication has been very effective in both preventing postopera-
tive persistent dysphagia and reflux. Only a limited fundic mo-
bilization is necessary to perform an anterior partial fundopli-
cation (Fig. 9.2.17). The mobilization of the fundus must involve
a limited portion, to the level of the upper pole of the spleen.
After finishing the posterior hiatoplasty, the anterior flap of the
through to the appropriate extent. It is very important for an optimal postoperative function that the correct part of the proximal stomach is pulled through the posterior gastroesophageal “window”. An alternative method is to push through to the right side. In this case the grasper is moved behind the esophagus from the left, carrying the posterior aspect of the fundus and pushing it over to the right side.
fundus is pulled over to the right crus. The upper border of the fundic flap is sutured to the distal esophagus (high pressure zone area) with 3 non-resorbable sutures. Attaching the ante­rior fundic flap with one stitch to the left side of the esophagus, one to the middle and one to the right side of the esophageal wall, the hemifundoplication is completed. An additional one or two stitches are used to fix the fundic flap to the right crus in order to assure the abdominal maintenance of the wrap.
Complications
Intraoperative Complications
Injury to the esophagus, cardia and stomach
Therapy: If there is an intraoperative suspicion of a wall lacera­tion, a test with methylene blue solution should be performed. Full thickness interrupted suture should be used to closed the defect and it should be covered with the fundus during fundo­plication. Drainage of the abdomen is the surgeon’s choice.
Prevention: During the dissection of the gastroesophageal junc­tion it is important to focus on identification of the right crus, the hiatal arch and then the lower mediastinum, rather than the esophageal wall. Once both right and left crus and the hiatal arch are dissected free, the esophagus usually is free and can be palpated with the laparoscopic instruments without any prob­lem. The dissection of the posterior aspect of the esophagus above the aorta is facilitated by dissection with blunt instru­ments.

9.2 Fundoplication and Partial Fundoplication Techniques
Fig. 9.2.13 Completed Nissen Rossetti Fundoplication.
Spleen injury
Therapy: Bleeding from small decapsulations or lacerations can be stopped with electrocautery, compression or laser coagula­tion. The surgeon should decide quickly whether the bleeding has a high probability of getting under control by laparoscopic means. If there is any doubt, immediate conversion is obliga­tory. Prevention: Usually spleen injuries occur during the mobiliza­tion of the fundus. Only a very careful dissection technique using gentle blunt dissection, clip applications, and if possible a harmonic scalpel help prevent splenic injury.
Liver injury
Therapy: Compression, laser coagulation, electrocautery, local hemostyptics, fibrin sealant or suture. Prevention: Liver injuries occur when the retractor is not handled in the proper way or when the liver tissue is very fragile. Only gentle manipulation and frequent control of the correct usage of the retractor can prevent liver laceration.
Fig. 9.2.14 Laparoscopic Hill procedure.
Pneumothorax
Therapy: A chest tube can be placed intraoperatively if there are respiratory problems. Prevention: Careful dissection without damage.
Postoperative Complications:
Dysphagia
Temporary dysphagia in the first postoperative weeks is not a complication, but a rather normal finding in patients after Nis­sen fundoplication. Patients should be informed about this problem prior to surgery. A real complication is persistent dy­sphagia continuing for months after surgery. Therapy: flexible endoscopic bouginage should be the first step. In severe cases with persistent dysphagia even after 3 months and bouginage treatment, a relaparoscopy can be considered by a well-experienced surgeon and correction of the wrap might be possible. If there is any doubt about the anatomy or limited exposure because of adhesions, a conversion is necessary.
CO2emphysema
Therapy: CO2emphysema is not a major problem when it is re- stricted to the trunk. If it is moving up into the neck and head, a conversion must be considered before skin damage occurs, e.g., at the eyelids:
− after reduction of intraoperative pressure to 8 mm Hg,
− postoperative respirator therapy for 2−3 hours until the CO emphysema dissolves.
Prevention: Low intraabdominal pressure reduces CO
insuffla-
2
tion. If in old patients the tissue seems to be very fragile and in cases where an extensive dissection of the lower mediastinum is necessary, CO
emphysema of the head and neck is likely. In
2
these cases, the mobilization of the fundus can be performed before dissecting the lower mediastinum thus reducing the operating time, once the CO
emphysema starts developing.
2
Recurrent or persistent reflux
Persistent reflux is usually due to a misplaced wrap around the proximal stomach. It can also occur in the early postoperative weeks because of early disruption of the wrap. Therapy: relaparoscopy by a well-experienced laparoscopic sur­geon and redo.
2
Slipped Nissen
Currently, this phenomenon occurs rarely, since the wrap is usually correctly anchored to the esophagus. Another method of reducing the incidence of this complication is an only limited dissection of the gastroesophageal junction at the lesser curva­ture which allows only a small space for the passage of the wrap. As a consequence, the wrap, when placed correctly, can­not move.
Fig. 9.2.15 Anterior 180° hemifundoplication.
255
Denervation symptoms
This complication is not very frequent. Usually, gastric empty­ing problems are clinically prominent. It can be also associated with temporary diarrhea and abdominal discomfort. Therapy: Prokinetic medication, if not successful surgical rein­tervention. Postoperative care: A nasogastric tube should be left in the stomach for 2 days for removal of air and fluid from the gastric lumen to prevent gastric dilation and early disruption of the wrap. It is a high probability that the patient will have early postoperative dysphagia because of a tissue edema at the gastroesophageal junction. Again, the patient needs to be in­formed about this problem prior to surgery. In the postoperative follow-up after 3 months or half a year an upper GI endoscopy should be performed to document persistance or healing of esophagitis.
Re-do fundoplications
These operations are technically very demanding, especially if an extensive dissection has been performed during the first operation. However, adhesions after gastrofundophrenicopexy or other pexy procedures can be very limited, so explorative la­paroscopy to check out the situation at the hiatus after previous operation can be reasonable. However the level of changeover to conversion must be very low. If there are severe adhesions and especially if the gastroesophageal junction is embedded into scar tissue, differentiation between the esophageal wall, vagus nerves, crura and scar tissue cannot be possible. For this kind of dissection the surgeon needs all tactile capacities of the human fingers. Therefore an early conversion or a primary plan to do a laparotomy is necessary.

9.3 Comments on Nissen Fundoplication

J. H. Peters, T. R. DeMeester
The surgical treatment of gastroesophageal reflux disease is ex­panding rapidly, largely due to the advent of laparoscopic tech­niques. Drs. Pier, Götz, and Fuchs have, in general, superbly out­lined the indications, patient selection and techniques of antire­flux surgery as practiced in their respective departments. Two
areas deserve specific comment; the indications for antireflux surgery and the technique of fundoplication. Drs. Pier and Götz (chapter 9.1) suggest that surgical therapy be restricted to patients “refractory to long term non-operative
treatment or severe esophagitis (grades III and IV).” We would like to outline a more cause and effect specific approach. The non-operative management of gastroesophageal reflux disease is improving rapidly. Most candidates for operation can, and should, be controlled with proton pump inhibitors prior to an-
tireflux surgery. Indeed, one should be cautious in operating on
a patient who has no response to medical treatment. Further, limiting antireflux surgery to patients with severe esophagitis
denies a large population of patients who are excellent candi-
dates for laparoscopic fundoplication the opportunity for cure
of their disease with a single intervention. For these reasons we have moved away from the concept of failure of nonoperative therapy as an indication for antireflux surgery. Rather, patients with symptoms of reflux disease are
thoroughly evaluated with respect to their risk of persistent and progressive disease. Patients presenting for the first time with
symptoms suggestive of gastroesophageal reflux may be given initial therapy with H2 blockers. Failure of H2 blockers to con­trol the symptoms, or immediate return of symptoms after stopping treatment suggests either that the diagnosis is incor­rect, or that the patient has relatively severe disease. Endo­scopic examination at this stage of the patient’s evaluation pro­vides the opportunity for early identification of complications including Barrett’s esophagus. Twenty four hour esophageal pH monitoring should be pursued to confirm the diagnosis. Esophageal manometry and/or ambulatory esophageal bile monitoring should also be done to identify features predictive of severe disease such as a mechanically deficient lower esophageal sphincter and duodenogastroesophageal reflux. In the absence of risk factors predictive of severe disease and esophageal mucosal injury, the patient’s symptoms may be con­trolled with proton pump inhibitors. Factors that predict a poor response to medical therapy, frequent relapses, and the development of complications include; supine reflux, erosive esophagitis or a columnar lined esophagus at initial presenta­tion, bile in the refluxate, and a structurally defective sphincter. Patients who have these risk factors should be given the option of surgery as a primary therapy with the expectation of long term control of symptoms and complications.
Although many internists and surgeons are reluctant to advise
operation in the absence of demonstrable esophagitis, we
256
9.3 Comments on Nissen Fundoplication
believe that one should not be deterred from considering an­tireflux surgery in a symptomatic patient provided the disease process has been objectively documented by 24 hour pH moni­toring. This is particularly true in patients who have become de­pendent upon therapy with proton pump inhibitors. Indeed, in­vestigations of the natural history of GERD in the absence of esophagitis have demonstrated return of symptoms in the ma-
jority of patients following cessation of nonoperative therapy.
The second area of comment relates to evolving concepts in the selection and technique of antireflux procedures. Antireflux surgery appears deceptively simple. Achieving a ninety plus
percent success rate is not as easy as it seems. Successful out-
come is highly dependent upon the meticulous performance of
the appropriate antireflux procedure in each patient. We would
agree with the selection of the various antireflux procedures as
outlined by Dr. Fuchs (chapter 9.2). Our experience suggests
that in approximately 80−90 percent of patients referred for
operative treatment a transabdominal Nissen fundoplication is
the most suitable procedure. The remaining 10−20 percent of
patients are best treated with an antireflux procedure tailored
to their underlying anatomic and functional abnormalities. This
approach results in excellent long-term relief of reflux symp-
toms across the whole spectrum of disease.
In addition, we believe that the advent of the laparoscopic ap-
proach provides an ideal opportunity for standardization of the
technique of Nissen fundoplication. The essential elements nec-
essary for the performance of a transabdominal fundoplication
are common to both the laparoscopic and open procedures and
include the following:
1. Crural dissection, identification and preservation of both
vagi including the hepatic branch of the anterior vagus.
2. Circumferential dissection of the esophagus.
3. Crural closure.
4. Fundic mobilization by division of short gastric vessels.
5. Creation of a short, loose fundoplication by wrapping the anterior and posterior wall of the fundus around the lower esophagus.
Although, considerable argument continues regarding the sig­nificance of technical aspects such as the orientation of the fun­doplication and the need for fundic mobilization and crural clo-
sure, there is growing evidence of the importance of these tech-
nical features. Several authors have compared the incidence of dysphagia following laparoscopic Nissen fundoplication with
short gastric vessels’ division, to dysphagia following the
Rosetti/Hell modification of Nissen’s (no division of short gastric vessels) procedure. Evaluation of these data would support the contention that complete fundic mobilization by division of vessels is important to allow construction of a tension free fun­doplication. Despite the fact that optimal results following open antireflux
surgery have included routine crural closure, the need for crural
closure in every patient continues to be debated. Although no prospective randomized studies exist, data are emerging to re­inforce the need for crural closure in all patients. Watson and
Jamieson have reported upon a 6.7% incidence of acute para-
esophageal herniation following laparoscopic fundoplication. Herniation occurred at a mean of 1 month after operation, and occurred in patients in whom crural closure was omitted. Of the
17 patients developing the complication only 3 had a hiatal re-
pair and then only with a single stitch. Ten of the 17 patients re­quired re-operation. Our early results stimulated us to look more closely at how we constructed the fundoplication with the laparoscopic approach.
Despite calibration with a 60F bougie, laparoscopic fundoplica­tion may result in a fundoplication that is tighter than that con­structed during an open procedure. One of the reasons may be the manner in which the wrap is constructed. Ideally, the ante­rior and posterior fundic wall should be folded around the distal esophagus to meet in the right lateral aspect of the esophagus rather than at the anterior or 12 o’clock position. Rudolph Nis­sen described this as a “Witzel” of the distal esophagus into the stomach. This can be difficult to achieve laparoscopically unless attention is given to complete fundic mobilization and the care­ful grasping of the posterior fundus to pass behind the esophagus. This is best accomplished by placing a Babcock clamp through the lower left port (surgeon’s right) and grasping a suitable portion of the posterior fundus. It is then passed be­hind the esophagus from left to right and grasped with the sur­geon’s left hand. We prefer this approach to the more common method of passing an instrument from right to left, as it assures passage of the posterior fundus and not the anterior one, during creation of the fundoplication. The anterior wall of the fundus is then folded over the esophagus above the gastroesophageal fat pad. Both posterior and anterior fundic lips are manipulated to allow the fundus to envelope the esophagus without twisting. With adequate dissection the right portion of the fundoplica­tion should rest comfortably in place without the tendency to retract back toward the spleen. A 60F bougie is then carefully passed under direct vision to properly size the fundoplication. The relative roles of medical versus surgical therapy for gastro­esophageal reflux disease are changing, as both patients and their physicians recognize that surgery provides the only known means of altering the natural history of the disease. At present, it seems that laparoscopic Nissen fundoplication will become the standard of care in the surgical treatment of patients with gastroesophageal reflux disease. Although laparo­scopic fundoplication results in control of typical symptoms in over 90% of patients, it should be recognized that achieving op­timal results requires careful patient selection and attention to meticulous technique. The lessons of history have allowed im­provements in antireflux surgery to the point that excellent re­sults can be achieved in the majority of patients. It is hoped that in this era of minimally invasive surgery, mistakes of the past will not be repeated by those who are unfamiliar with the pathophysiology of the disease or the history of antireflux surgery.

9.4 Gastropexy in Paraesophageal Hiatus Hernia Repair

F. Köc kerling

Goals and Methods
Paraesophageal hiatus hernias account for about 10% of all dia­phragmatic hernias. This type of hernia is characterized by dis­placement of part of the fundus or of the entire stomach into the mediastinal space next to the esophagus in the absence of axial
dislocation of the cardia (upside-down stomach). Complications must be expected often after the disorder has been asymptomatic for a long period of time. In addition to chronic anemia, occult bleeding, and impaired motility, life­threatening complications such as perforation, strangulation, gangrene, obstruction, or pulmonary problems may occur in 27% of patients. Due to the high morbidity and mortality as-
sociated with these complications, operative repair is indicated
whenever a paraesophageal hiatus hernia is diagnosed.
Gastropexy with closure of the esophageal hiatus has proven to be
a safe and effective surgical procedure. Generally, the part of the
stomach that has herniated into the chest is easily reduced, be-
cause adhesions are rare. These circumstances represent a
favorable situation for laparoscopic gastropexy. After replacing
the stomach into the abdomen, the surgeon sutures the fundus
to the inferior aspect of the diaphragm and repairs the dia­phragmatic esophageal hiatus. This procedure requires that the surgeon be sufficiently accomplished in the laparoscopic manipulation of hollow organs and in laparoscopic suturing and knot-tying techniques.
Note: Preoperative diagnostic studies must confirm the absence
of a composite hiatus hernia, since cephalad expansion of a pri­marily axial sliding hernia can result in paraesophageal dis­placement of parts of the fundus of the stomach. In such cases,
gastropexy must be combined with a Nissen fundoplication.
patient must be made aware of possible problems of la­parotomy. If prosthetic material is to be used to close the defect of the enlarged esophageal hiatus, the problems of implanting a nonabsorbable mesh should be discussed. The patient should also be informed of the general level of experience with laparo­scopic gastric surgery at a given institution.
Special Preparations
As in all procedures in the region of the lower esophageal sphincter, a large nasogastric tube is placed to identify the esophagus. An indwelling urinary catheter is indicated, as in any procedure involving the establishment of a pneumoperi­toneum with a Veress needle and the percutaneous placement of the laparoscope/camera trocar.
Anesthesia
General anesthesia.

Indications
Gastropexy is indicated in the presence of a confirmed para­esophageal hiatus hernia (which may remain asymptomatic) with only partial displacement of the stomach into the chest.
Contraindications
− Paraesophageal hernias with complications (bleeding, necrosis of the stomach wall, ulceration, or perforation).
− Displacement of the entire stomach into the chest (upside­down stomach).
− Presence of general or anesthetic laparoscopic risk factors.
Surgical Risks and Patient Information
Complications of gastropexy and repair of the esophageal hiatus in general must be discussed with the patient, who must also be informed of the specific laparoscopic complications involved
with establishing the pneumoperitoneum and placing the tro-
cars. The patient must also be aware that if laparoscopic reposi-
tioning of the stomach is not feasible or intraoperative compli-
cations such as bleeding or perforation of a hollow viscus occur,
the surgeon must convert to an open procedure. Therefore the
Complications
Intraoperative Complications
− Arterial or venous bleeding from placement of the Veress needle or laparoscope/camera trocar.
Fig. 9.4.1 Gastropexy. Positioning. The patient is placed supine with the left arm tucked to his or her side and the right arm extended to facilitate intravenous access. After establishing the pneumoperitoneum and inserting the laparoscope/camera trocar, move the patient into a 20−30° reverse Trendelenburg position so that the greater omentum, transverse colon, and small intestine fall into the lower abdomen.
