8.3 Selective Proximal Vagotomy
Post-vagotomy syndrome with dysphagia and/or diarrhea is rare following selective proximal vagotomy. Excessive suture mate- rial at the operative site may contribute to formation of granulomas. Corrective action: Endoscopy can be used to remove intralumi­nal suture material.
Bleeding
Corrective action: In the presence of clinically diagnosed bleed­ing and free peritoneal fluid detected via ultrasound, repeat la­paroscopy or conventional laparotomy is indicated if the patient requires a significant transfusion for stabilization. If difficulties are encountered during a second laparoscopic approach (such as locating the source of bleeding or using suction), immediate conversion to laparotomy is indicated. Note: Repeat, corrective laparoscopy requires the highest level of surgical skills and expertise.
T4
Necrosis of the Stomach Wall
Partial gastric wall thermal necrosis is generally localized to the lesser curvature and is produced by electrocautery. Caution: Using monopolar electrocautery can produce thermal tissue damage and is usually not through the entire gastric wall thickness. Corrective action: Placement of a nasogastric tube and parenteral feeding are indicated. Usually the lesion will heal
spontaneously. Perform endoluminal endoscopic follow-up ex-
amination if necessary. If the lesion persists or involved the en­tire gastric wall thickness when the mishap occurred, la­parotomy and repair are indicated.
Peritonitis
Immediate conventional laparotomy is indicated in the pre-
sence of suspected or confirmed peritonitis.
Mediastinitis
Injury to the esophagus can result in infection of the medi­astinum. Initially, the infection may remain without clinical symptoms. Corrective action: Immediate laparotomy, drainage, and repair are indicated if this complication is suspected.
Pleural Effusion
A pleural effusion may accompany a perforation of the esophagus in the presence of mediastinitis regardless of whether the pleura itself is open or not. Corrective action: First aspirate the pleural effusion and drain it. If esophageal or gastric leakage is detected, laparotomy is indi­cated to suture the defect. Fundoplication and placement of a drain may be necessary (see Fig. 8.3.15 ).
Gastric Atony
Treat with motility agents and place a nasogastric tube.

Fig. 8.3.3 Selective proximal vagotomy. Trocar placement. A total of five ports is required. Insert a 10.5-mm laparoscope/camera tro­car (T1) with a trumpet valve into the abdominal cavity about two finger breadths above the umbilicus after establishing the pneumoperitoneum. Then insert four working trocars under laparoscopic vision. Ports T3 and T5 contain 10.5-mm instrument trocars for various dissection instru­ments. An additional 5.5-mm instrument trocar at port T4 is inserted to permit introducing a retractor to lift the left hepatic lobe. We recommend intraluminal splinting and transillumination of landmarks with a gastro­scope. Open trocar placement is an alternative.
Symptomatic Gastroesophageal Reflux
In most cases, preoperatively symptomatic gastroesophageal reflux was present. Corrective action: Treat nonoperatively at first. If this is un­successful, conventional Nissen fundoplication is indicated.
Late Complications
Pyloric Stenosis
Persistent or recurrent ulcers can lead to pyloric stenosis. Corrective action: Initiate adequate nonoperative therapy and careful endoscopic dilation of the pylorus. Where this is unsuc­cessful or complications occur, surgical intervention is indicated.
Suture Granulomas
The clinical significance of suture granuloma varies. Corrective action: Endoscopy can be used to remove intralumi­nal sutures.
Recurrent Ulcer
Ulcers recur in 4−10% of all patients. Contributing factors in­clude the patient’s dietary habits, the surgical technique, and persistent infection with Helicobacter pylorii. As long as laparo­scopic selective proximal vagotomy with a circular esophageal myotomy remains unfeasible, a higher incidence of recurrence must be expected. Corrective action: Nonoperative treatment. Exclude chemical and toxic factors, and treat infection due to Helicobacter pylorii. Conventional surgical intervention is indicated in the presence of a persistent ulcer or complications.

Step-by-Step Procedure
I Technical preparations
1. Adjust the electrocautery unit to an average setting.
2. Connect the aspirator/irrigator set.
3. Prepare an endoluminal endoscope.
4. Start the video and recording unit.
II Establishing the pneumoperitoneum
1. Select pressure levels according to patient’s size, age, and weight (6−8 mm Hg for children; 10−14 mm Hg for adults).
2. Connect all instruments required for operation.
3. Make a skin incision about two finger breadths above the
umbilicus for the Veress needle and laparoscope/camera tro-
car.
4. Insert the Veress needle.
5. Perform safety tests: injection, aspiration, “slurp,” manome­ter, and rotation test.
6. Perform insufflation procedure.
Caution: Insufflate infants at 1 l/min maximum.
III Laparoscopy
1. Place nasogastric tube.
2. Insert laparoscope/camera trocar with tapered blunt-tip sty-
let about two finger breadths above the umbilicus directly
through the linea alba.
3. Insert the instrument trocars in the left and right upper abdo-
men under laparoscopic visualization.
4. Explore the peritoneal cavity.
5. Check the diameter of the pylorus (in the presence of an un­complicated duodenal ulcer).
6. Retract the antrum and body inferiorly.
7. Identify the anterior gastric branch (nerve of Latarjet) and the crow’s foot.
8. Incise the lesser omentum along the lesser curvature.
9. Completely expose each neurovascular bundle as the dissec­tion progresses caudally.
10. Place two clips on each bundle after coagulation with bipolar electrocautery and transect between clips.
Caution: Thermal tissue damage can result.
11. Dissect as far as the cardia.
12. Clear the anterior aspect of the esophagus above the GE junc­tion.
13. Prepare and incise the posterior peritoneal attachments with their neurovascular structures at the cardia.
14. Expose and transect the fundic (criminal) branch at the left
lateral margin of the esophagus. Optional: Perform anterior
fundoplication (see p. , Fig. 8.3.15).
15. Close the serosa of the lesser curvature.
16. If necessary, transect the right gastroepiploic neurovascular structures.
17. Remove the trocars under laparoscopic visualization.
Caution: Residual bleeding from the trocar incisions may occur.
Operative Technique

Fig. 8.3.4 Principles of selective proximal vagotomy. In selective proximal vagotomy, the gastric branches, the “criminal” branch, and the gastroepiploic branch are transected. The gastroepiploic branch is divided along the greater curvature where the gastric antrum and body join. The selective proximal vagotomy preserves the two main trunks, the anterior and posterior antral branches, the hepatic branches, and the celiac branches. In the presence of pyloric stenosis, pyloroplasty is indi­cated. As in surgical repair of the esophageal hiatus or truncal vagotomy, the esophagus is splinted with a large nasogastric tube.

Fig. 8.3.5 Selective proximal vagotomy. Dissecting along the lesser cur-
vature. After identifying the course of the cephalad branch of the crow’s foot (of the anterior antral branches), begin proximal to this level with the dissec­tion along the lesser curvature (see arrow in Fig. 8.3.4). Apply tension to the stomach inferiorly (port T2), lift the lesser omentum (port T4), and open the peritoneal membrane with scissors (port T3). Next, pass a curved grasper through the avascular portions of the anterior connective tissue and lift out the tissue containing the neurovascular bundle (insert).

Fig. 8.3.7 Selective proximal vagotomy. Dissection. Expose the superior portion of the lesser omentum and the perie-
sophageal tissue while preserving the anterior vagal trunk. The dissection extends past the esophagus to the left in an obliquely cephalad direction.
Fig. 8.3.6 Selective proximal vagotomy. Dissecting along the lesser cur­vature. The dissection begins distally and extends from below upwards. Use bipolar electrocautery (insert) to coagulate the individual neurovascular structures isolated previously by blunt dissection. Two clips are applied, one close to the wall of the stomach and the other peripherally, and the nerve and vascular branches are divided between the clips. Control minor bleeding with bipolar electrocautery. Caution: Thermal damage to the lesser curvature can produce necrosis.

through port T4 to lift and expose the vascular structures to be ligated.
Then you may clip them as described in Fig. 8.3.6 or ligate them with pre-
tied extracorporeal Roeder knots or intraabdominal surgical knots.
Fig. 8.3.9 Selective proximal vagotomy. Exposing the terminal esophagus. Dissecting the lateral and posterior cardia and the esophagus is difficult.
We recommend using a 30-degree angled laparoscope for better visuali­zation of the operative site. Flexible-tipped scissors and graspers are best in this situation (see Fig. 8.3.3 for key to instrument numbers).

Finally, close the serosa of the lesser curvature with interrupted
seromuscular sutures. Use absorbable suture material (3 × 0, metric 2) 15−20 cm long. We recommend a slip knot secured with an additional locking knot or surgeon’s knot.
The right gastroepiploic branch of the vagal trunk is contained in the
vascular bundle of the right gastroepiploic vessels. Divide this branch
where the antrum and the body join. Finally, verify hemostasis and place a
suction drain (see Fig. 8.3.3 for key to instrument numbers).

Fig. 8.3.14 Selective proximal vagotomy. Complication: tear in the

esophagus. If you suspect that a perforation has occurred, inject a dilute methylene blue solution into the esophagus (see Fig. 8.3.3 for key to in-
strument numbers).
Corrective action: Repair the defect with closely placed interrupted su-
tures, and cover it with a partial fundoplication. Manage the defect via laparotomy.

Complications
Intraoperative Complications
− Perforation of the esophagus.
− Perforation of the stomach. Corrective action: Close with interrupted sutures running through all organ layers. Clamp the distal stomach and verify the closure with a dilute methylene blue solution injected through a nasogastric tube (see also Fig. 8.3.15).
Postoperative Complications
Thermal damage to the stomach wall with delayed necrosis, perforation, and peritonitis. Pseudo-obstructions (Ogilvie’s syndrome) can occur in about 4% of all patients. Corrective action: Where symptoms persist for five days or longer, endoscopy is indicated with dilatation of the pyloric ring if necessary. Undetected thermal necrosis of the lesser curvature can lead to peritonitis.
Step-by-Step Procedure
I Technical preparations
1. Adjust the electrocautery unit to a medium setting.
2. Connect the aspirator/irrigator set
3. Prepare a gastroscope.
4. Start the recording unit.
II Establishing the pneumoperitoneum
1. Select pressure plateau according to patient’s size, age, and weight (6−8 mm Hg for children; 10−14 mm Hg for adults).
2. Connect all equipment required for operation.
3. Make a skin incision about two finger breadths superior to the umbilicus for the Veress needle and laparoscope/camera tro­car.
4. Insert the Veress needle.
5. Perform safety tests: injection, aspiration, “slurp,” manometer, and rotation tests.
6. Perform insufflation procedure.
Caution: Insufflate children at 11/min maximum.
III Laparoscopy
1. Place nasogastric tube or orogastric bougie.
2. Insert laparoscope/camera trocar with tapered blunt-tip stylet about two finger breadths superior to the umbilicus directly through the linea alba.
3. Insert the instrument trocars under laparoscopic visualization.
4. Explore the peritoneal cavity with the 30-degree laparoscope.
5. In female patients, explore the reproductive organs with a probe to lift and displace organs, for better visualization.
6. Lift and incise the gastrophrenic ligament at the cardia. Expose the posterior vagus nerve and excise a 1−1.5-cm segment.
7. Perform a seromyotomy with monopolar electrocautery along and 2−3 cm inside the lesser curvature.
8. Close the seromyotomy with a continuous suture.
9. Remove the instrument trocars under laparoscopic vision.
Caution: Residual bleeding from the trocar incisions may occur.

Operative Technique
Fig. 8.4.4 Posterior truncal vagotomy and anterior gastric seromyo-
tomy. Schematic overview of surgical objectives in seromyotomy with posterior truncal vagotomy (Taylor’s operation). A seromyotomy is performed along the lesser curvature from the cardia notch to the crow’s foot to
denervate this portion of the stomach. The operation leaves the antral branches, the pyloric branch, and the hepatic branches of the vagus nerve intact whereas the seromyotomy transects the proximal fundic nerves (see also Fig. 7.1.4).

The initial steps in the procedure are similar to any truncal vagotomy. Lift
the gastrophrenic ligament with a grasper and incise it at the level of the
esophagus. Elevate the left hepatic lobe with a retractor inserted through port T5 to obtain optimum exposure of the surgical site. After exposing
the right and left margins of the esophageal hiatus, rotate the esophagus
with a swab and dissect above the abdominal aorta to expose the poste­rior vagal trunk. After identifying the nerve, expose it completely, divide it
with bipolar electrocautery, and resect about 1 cm of the nerve (see Fig. 8.4.3 for key to instrument numbers).

Begin at the cardia, coursing distally to about 1 cm proxi­mal to the crow’s foot. Perform the seromyotomy using monopolar elec­trocautery. Caution: Do not injure the gastric mucosa (see Fig. 8.4.3 for key to instrument numbers).
Trocar Placement

wound when driving the needle. Use absorbable suture material (3 × 0,
metric 2) and a curved needle. The suture should be 15 cm long, secured
with a pre-tied initial knot (see Fig. 8.4.3 for key to instrument numbers).

8.5 Anterior and Posterior T runcal Vagotomy and Pyloroplasty

A. Pier , F . Götz
Goals and Methods
Anterior and posterior truncal vagotomy is the simplest method of achieving gastric denervation. It may be performed laparos­copically, or thoracoscopically for patients who have undergone a previous gastric operation. Since the antrum is denervated with truncal vagotomy, a pyloroplasty is indicated.
Abdominal Truncal Vagotomy
with the patient placed into a moderate left lateral decubitus position. The monitors with the video recorder and light source are located to the patient’s right side. The respirator and the an­esthesiologist are off to the left. Electrocautery unit is positioned on the right side of the patient.
The aspirator/irrigator set and a second monitor for the first as­sistant if available are on the left. The insufflator is placed in the first assistant’s visual field. For the techniques described below, a 30-degree laparoscope is essential for better visualization of the surgical site.

(Fig. 8.5.3).
Intraoperative Complications
Perforation of the Esophagus
The most serious complication is a perforation of the esophagus. If a perforation is suspected, clamping of the GE junction and injecting a dilute methylene blue solution into the esophagus through a nasogastric or oropharyngeal tube will allow identification of the leak. Corrective action: Repair the defect with closely placed inter­rupted sutures, cover it with a gastric fundoplication (Fig.
8.3.15), and test the repair for patency. Manage the defect via a laparotomy if necessary.
