11.4 Laparoscopically Assisted Left Hemicolectomy
Step-by-Step Procedure
(Figs. 11.4.8 to 11.4.11)
1. The patient is placed on the operating table in the supine position. The surgeon and the camera operator stand at the right side of the table and the first assistant stands at the left.
The TV monitor is caudad to the patient’s left hip.
2. A 2-cm vertical skin incision is made at the infraumbilical area.
A vertical incision is then made at the linea alba and the peri­toneal cavitiy is entered. A 10-mm blunt trocar is placed and secured.
3. A pneumoperitoneum using CO peritoneal cavity is then explored and other trocars are placed under the direct vision as in Figure 11.4.1.
4. The operating table is placed in Trendelenburg position and
tilted to the right to shift the small bowel medially and out of the pelvis.
5. Using an Endo Babcock, the left colon is retracted medially
and is mobilized using scissors and electrocoagulation along the white line in the left paracolic gutter (Fig. 11.4.2a, b).

6. The patient is placed in reverse Trendelenburg position and the splenic flexure is pulled inferomedially to take down the splenic flexure (Fig. 11.4.2a, b).
7. The mesocolic vessels and mesocolon are clipped or divided with the Endo GIA stapler (Fig. 11.4.2b).
8. The segment of colon to be resected is exteriorized through an oblique muscle-splitting incision in the left lower abdomen
(Fig. 11.4.3).
9. The specimen is held with a bowel clamp peripheral to the
projected anastomotic site and an extraabdominal side-to-
side anastomosis is made with the GIA stapler at the appro-
priate level of cranial and caudad bowel transection (Fig. 11.4.4).
10. The bowel limbs are closed with a single application of the TA 90 stapler in healthy tissue, including the GIA introduction site with the specimen. The specimen is then transected using the TA stapler as a guide (Fig. 11.4.5).
11. After inspecition of the anastomosis (Fig. 11.4.6), the left
lower quadrant incision is closed and the pneumoperitoneum is re-established and the final inspection of the abdominal
cavity is performed (Fig. 11.4.7).
12. The pneumoperitoneum and the trocars are removed and the trocar sites closed in a standard fashion.
Operative Technique
Fig. 11.4.1 The patient is placed in a supine position and prepped. The pneumoperitonium is created using CO
cal port. Normally four trocars are used for a left hemicolectomy. A 10-
mm trocar is placed at the umbilicus. The peritoneal cavity is then visually
explored. The other trocars are placed under the direct vision. A 10- to 12­mm trocar is placed lateral to the left rectus muscle and slightly above the umbilicus (this can be a 5-mm trocar for grasping forceps and scissors),
followed by a 10- to 12-mm trocar lateral to the right rectus muscle and
just below the umbilicus, and another 10- to 12-mm trocar in the right lower quadrant for Endo GIA, Endo Babcock and other instruments.

Fig. 11.4.2a, b The operating table is rotated toward the right side, in
the Trendelenburg position to shift the small bowel medially and out of the pelvis. Using an Endo Babcock the left colon is retracted medially and
is mobilized along the line of Toldt in the left paracolic gutter, with scis-
sors and electrocoagulation. To take the splenic flexure down, the patient
a b
is placed in a reverse Trendelenburg position and special care is taken during the dissection to avoid splenic injury. The mesocolic vessels and mesocolon are clipped or divided with the Endo GIA stapler. Every at­tempt is made to identify the ureter and minimum coagulation is used around the ureter.
Fig. 11.4.3 After satisfactory mobilization of the colon, a small oblique incision is made into the left abdomen and the segment of colon to be re-
sected is exteriorized. Release of pneumoperitonium helps the colon to
be more easily delivered through the incision.
Fig. 11.4.4 The specimen is held with a bowel clamp distal to the pro­jected anastomotic site and an extraabdominal side-to-side anastomosis is made with the GIA stapler at the appropriate level of cranial and caudad bowel transection.

Fig. 11.4.5 Following this anastomosis, both bowel limbs are closed with
a single application of the TA 90 stapler in healthy tissue, including the
GIA introduction site with the specimen. The specimen is transected using
TA stapler as a guide. By using this stapling technique, the stapler is fired
only twice (once for the anastomosis and another one for closure and
transection of the specimen), rather than four times (twice for dividing proximal and distal bowel, once for anastomosis, and once for closure of
anastomosis).

11.5 Combined Endoluminal and Open Colon Procedure

11.5 Combined Endoluminal and Open Colon Procedure
S. D. Potter , H. Rajdeo, K. Bhuta, L. R. M. Del Guercio
Objectives and Methods
Endoluminal endoscopy is widely used for the preoperative assessment of gastrointestinal disease, to identify location and nature of the disease process. This useful technique of intralum­inal evaluation has not been widely utilized as an intraoperative tool. There are many occasions when the fiberoptic gastroin­testinal endoscope or colonoscope could guide the open or la­paroscopic dissection of severely scarred or matted intestine, facilitate the localization of fistulae, and help in the definition of anastomotic variations used after previous resections of the
stomach, small and large bowel, especially in the absence of re-
liable records. This chapter discusses a situation in which a complicated abdominal procedure was enhanced by the use of intraopera­tive fiberoptic endoscopy (ILE).
Indications
Complicated fistulae not clearly identified radioscopically or
clinically.
History of multiple operations with or without intestinal re-
sections; no clear description is available.
Primary gastric or esophageal resections, to aid in the inter-
nal definition of landmarks and margins.
Pedunculated colon lesions.
Position of Surgeon and Equipment
The surgeon is positioned in the usual place required for the procedure to be performed. The endoscopist is either at the head for upper endoscopy or between abducted legs (lithotomy position) for colonoscopy. The monitors can be placed either on the right and the left side of the patient, near the shoulders. For the combined endoluminal and intracavitary videoendoscopic procedures, one monitor is dedicated to each one of the pro­cedures.
Complications
Operative Complications
The same risks present during endoluminal endoscopy are pre­sent during intraoperative endoscopy. These risks include per­foration and bleeding. Given the complicated nature of the operation that requires intraoperative endoluminal endoscopy, the occurrence of these complications tends to be higher unless extreme care is taken. The patient should be made aware of the risks, however, he or she should also be aware that the compli­cations can usually be managed satisfactorily if noted in­traoperatively. While the risk of injury can be higher, the overall operative risk and successful outcome may be improved with the use of intraoperative endoluminal endoscopy.
Contraindications
Active intraluminal bleeding can interfere with visualization
and slow the operative procedure when expeditious action is most needed.
Severe, acute inflammation which can lead to perforation.
Instruments
Fiberoptic gastroscope and colonoscope.Various videoendoscopic or traditional instruments.
Position
The patient is generally in the supine position for abdominal procedures, but this may vary depending on the operation.
Postoperative Complications
The most serious postoperative complication is a missed in­traoperative bowel injury. Although bowel injury is sometimes difficult to avoid, immediate identification and repair will usu­ally prevent postoperative difficulties and limit operative mor­bidity. If an injury is not noted during the operation however, poor recovery, fistulae, severe sepsis, and even death may ensue. To prevent this disastrous outcome, meticulous dissec­tion and examination of the bowel intraoperatively are man­datory.
Operative Procedure
Figures 11.5.1 to 11.5.3 illustrate reoperation in a man with a history of a right hemicolectomy with ileotransverse colostomy for Crohn’s disease. He had developed a retroperitoneal abscess and enterocutaneous fistula postoperatively. At reexploration, the patient was placed in the lithotomy position to facilitate colonoscopy. The colonoscopy demonstrated a fistula at the site of the ileotransverse colon anastomosis. A retroperitoneal ab­scess communicated with the bowel at the same site. Drains were placed in the retroperitoneum, and the fistula was closed with staples. An omental patch was fashioned to cover the fistula repair. The entire colon and distal small bowel were clearly visualized with the colonoscope. This simplified ther­apeutic measures that could have been treacherous without this combined approach.
Step-by-Step Procedure
1. The patient is placed on the operating table in the supine posi­tion if gastroscopy is planned, whereas the lithotomy position is best for colonoscopy.
2. The endoscope is advanced into the esophagus and stomach or
rectum and colon under visualization either via the eyepiece or
on the video monitor. The pathology or anatomy in question is identified, and the endoscopist communicates this information to the surgeon. Both share in decision making.

Fig. 11.5.1 A previous right hemicolectomy for Crohn’s disease had been complicated by retroperitoneal abscess and enterocutaneous fistula. Colonoscopy at the time of reoperation showed the fistula to originate from the ileotransverse colon anastomosis and to communicate with the skin and the retroperitoneal abscess. The abscess was drained.

Fig. 11.5.2 The fistula was closed in healthy bowel with the linear stapler, under intraluminal, endoscopic surveillance.
Fig. 11.5.3 The linear staple closure was covered with an omental flap. The lumina of large and small bowel were examined again by endoscopy, to insure complete repair of the fistula and rule out any other endoluminal pathology.

12. Laparoscopically-Guided/Assisted Colo-Rectal Procedures

12.1 Repair of Perforations of the Colon and Rectum

F. Köc kerling
Goals and Methods
“Rare events are rare, but they do occur.” This maxim also ap­plies to instrumental, i. e., iatrogenic, unintentional perforation of the wall of the large bowel and the rectum. Thirty-seven percent of endoscopic perforations of the large bowel occur in the sigmoid colon, 26% in the rectum, 9% in the descending colon, 14% in the transverse colon, and 6% in the as­cending colon. Mortality from endoscopic perforations of the large bowel rises with the time elapsed until operation—from
17% at up to eight hours to over 50% at 24−48 hours. If abdomi-
nal symptoms occur following diagnostic or therapeutic colo­noscopy with evidence of air in the abdominal cavity or the con­trast enema reveals a defect, immediate surgical repair is indi­cated. If this condition is accompanied by other pathological findings, such as sigmoid diverticulitis or sigmoid carcinoma, the objective of surgical intervention will be to repair the iatro­genic perforation and resect the pathological process. When di­agnostic colonoscopy has produced no pathological findings or when a polyp has already been removed endoscopically, surgi­cal intervention is indicated to suture the defect or resect the af­fected segment. Conditions are best when the diagnosis is made early and colonoscopy has been preceded by intestinal lavage. Escape of fecal material can usually be avoided if the diagnosis is reached promptly. The conditions for laparoscopic repair of an endoscopic colorectal perforation may be favorable in such cases.
Surgical Risks and Patient Information
The patient should be informed about the opportunities that la­paroscopic colorectal surgery offers, specifically as regards re­pair of an isolated iatrogenic colorectal perforation. The surgeon should mention that this was not previously an established sur­gical procedure. Since this complication is rare, the surgeon will not generally have much experience in correcting it. Accord­ingly, the surgeon should refer to other laparoscopic colorectal procedures in assessing the risks when informing the patient, and he or she should mention possible complications in laparo­scopic colorectal surgery. This includes the risk of repair failure or infection.
Special Preparations
Preoperative bowel preparation should precede colonoscopy, and not too much time should have elapsed between the bowel preparation and the diagnosis. Presence of intraabdominal air on the plain upright chest X-ray and a contrast enema can con­firm the diagnosis of endoscopic perforation. Further prepara­tions include placement of a nasogastric tube and urinary catheter.
Anesthesia
Indications
Iatrogenic or accidental colorectal perforations following diag­nostic or therapeutic colonoscopy, in the absence of pathologi­cal colon findings and established peritonitis, may lend them-
selves well to laparoscopic repair if the bowel has been pre-
pared for endoluminal endoscopy prior to the injury.
Contraindications
If a colorectal lesion requiring separate operative treatment is present in addition to the endoscopic perforation, conventional operation is indicated to treat both conditions simultaneously. If the interval between perforation and operation is excessive and there is clinical evidence of peritonitis, the lesions should be approached by laparotomy. Conventional operation is also indicated to repair extensive tears in the wall of the colon in the absence of any preexisting lesions.

For laparoscopic repair of iatrogenic perforations of the sigmoid colon, rectum, ascending colon, and distal segment of the descending colon, place the patient on an operating table for rectal surgery in an extreme
Trendelenburg position (inclined 30−40°). Shoulder and pelvis supports should be used to restrain the patient and permit inclining the operating
table in any plane during the procedure. To reduce the risk of compart­ment syndrome and compressive neuropathies, enclose the patient’s knees and calves in thick foam rubber cushions and venodyne boots.

for anesthesia. A second
assistant stands next to
the patient’s right leg, and
the operating room nurse
stands next to the patient’s left leg with the instrument table. The monitor, insufflator, and light source are located between the patient’s ab-
ducted legs. The electro-
cautery unit and the
aspirator/irrigator set can be positioned more or less
as desired.

Complications
Intraoperative Complications
− Bleeding from the trocar incisions.
− Damage to major intraabdominal or retroperitoneal vascular structures when establishing the pneumoperitoneum or placing the trocars.
− Perforation of hollow organs caused by insertion of the Veress needle and placement of the trocars.
Monitor Insufflator
− Subcutaneous emphysema.
− Lesions to the colon from grasping instruments.
− Bleeding when the colon is mobilized.
− Thermal injury to intraabdominal organs.
− Enlargement of the defect caused by a technically deficient attempt at closure.
Corrective action: Most of the intraoperative complications listed here should be managed by conversion to laparotomy.

Fig. 12.1.4 Repair of iatrogenic perforations of the colon and rectum. In­traluminal diagnosis. If laparoscopic examination cannot localize the lesion because the per­foration site is covered by the mesenteric attachments or is in the fixed part of the colon, intraoperative colonoscopy performed under laparo­scopic control may be helpful. Visually, the endoscopic perforation may appear as a localized puncture, a long tear in the wall of the colon, or any­thing in between. If there is an extended tear in the wall of the colon, it can only be managed by resecting the affected segment of the colon. Whether such damage can be treated laparoscopically depends on loca­tion of the lesion and the surgeon’s skill and experience. Laparoscopic re­pair of a torn colon by segmental resection is possible in principle (see la­paroscopic sigmoid colon resection and laparoscopic hemicolectomy, right). Note: This represents another example of combined endoluminal and in­tracavitary endoscopy (or open operation if needed).

Closing the lesion with staples. Often the damage consists of a puncture or localized laceration of the in­testinal wall. Repairing the lesion laparoscopically will also require mobil-
izing the affected segment of the colon along Gerota’s fascia to permit
closing the defect without creating tension. The sigmoid, descending,
and ascending colon are mobilized and exposed in the same manner as in laparoscopic sigmoid resection or laparoscopic hemicolectomy. After mo­bilizing the bowel, grasp the defect with two 5-mm graspers (T2 and T5). Place transverse tension on the colon, everting and opposing the edges of
the defect. Now close the defect with a linear stapler (30 mm or 60 mm;
T3) and excise the excess tissue beyond the stapler with the instrument used as guide for this excision.

Fig. 12.1.6 Repair of iatrogenic perforations of the colon and rectum. Closing the lesion with sutures. If the lesion is a localized puncture or an extended seromuscular defect that does not compromise the mucosa, the perforation may be closed
with interrupted sutures. Laparoscopic sutures with intracorporeal or ex­tracorporeal knot-tying may be used. If the entire thickness of the colon is perforated, the defect may also be closed with a transverse suture. If the seromuscular coat has been peeled off the colon over a large area without compromising the mucosa, anatomic reconstruction of the seromuscular coat is possible (see Fig. 12.1.3 for key to instrument numbers).

12.2 Repair of Rectal Prolapse

F. Köckerling, I. Gastinger
Goals and Methods
In a prolapse of the rectum, the proximal wall of the rectum is invaginated into the rectal lumen and b eyond into or through
the anal canal. The prolapse generally begins with the anterior
rectal wall, rarely with the posterior wall, and often involves the
entire circumference. We refer to an inner prolapse or an intus-
susception when the invaginated rectal wall stops short of the
closed anal canal or enters it without projecting beyond it. In a
complete rectal wall prolapse, the entire invaginated rectal wall protrudes through the anus. Patients with a prolapse of the rectum may present with normal
continence or varying degrees of incontinence. In the absence of neurological disorders or traumatic sphincter damage, the in-
continence will most probably be due to impaired stool sensa-
tion, possibly as a result of irritation of the stretch receptors, re-
duced sensitivity of the anal canal, and/or overstretching the
continence organ with increased secretion of fluid, mucus, and
blood from the prolapsed mucous membrane. Fifty percent of
the patients relate a history of constipation. Occasionally, this is regarded as the cause of the prolapse of the rectum.
There are well over one hundred surgical procedures for treat-
ing prolapse of the rectum. We differentiate between:
1. extraabdominal, anal, perineal, or perianal surgical pro­cedures and
2. intraabdominal surgical procedures with bowel resection or bowel conservation and suspending-anchoring the recto­sigmoid and mesorectum-sigmoid to the presacral fascia and left lower abdominal gutter.
Criteria for assessing the quality of various procedures are the incidence of recurrence and improvement in continence and colon function.
The extraabdominal, anal, and perineal corrective procedures may be performed under spinal or epidural anesthesia. However, these methods have a high rate of recurrence and thus should only be used in elderly patients with serious systemic complications. In the absence of increased surgical or anesthetic risk factors, the surgeon should use the abdominal procedures for correcting prolapse of the rectum.
A low rate of morbidity and recurrence indicate Well’s rec­topexy as the procedure of choice. Statistical surveys have re­vealed a mortality rate of 1.2% and a rate of recurrence of 3% for
