COMPLICATIONS

Leakage from an ileocolonic or colocolonic anasto­mosis may manifest as peritonitis, colocutaneous fi stula, or localized intraperitoneal abscess. Localized or spreading peritonitis should be managed by prompt relaparotomy and exteriorization of both ends of the anastomosis.
Sepsis in the subhepatic, subphrenic, or pelvic areas is an occasional complication of anastomoses of the colon, even in the absence of leakage. CT of the abdomen generally provides the diagnosis, and percutaneous drainage is usually successful.
Wound infection requires prompt removal of all overlying skin sutures to permit wide drainage of the entire infected area.

INDICATIONS

Ileocolic Crohn’s disease
Endoscopically irretrievable adenomatous polyps
Arteriovenous malformations
Cecal volvulus
Ischemia
Carcinoma
Right-sided diverticulitis

PREOPERATIVE PREPARATION

Preoperatively, patients undergo an appropriate medical evaluation. Imaging studies including CT scan, barium studies, and colonoscopy are under­taken for preoperative planning to assess the loca­tion of disease, review any associated complications, and identify any synchronous lesions. Preoperative marking of polyps by endoscopic tattooing using India ink is necessary to ensure intraoperative identifi cation of the lesion and to avoid the need for intraoperative colonoscopy. In patients with recurrent Crohn’s disease or history of multiple laparotmoies, imaging studies are particularly important in providing “roadmaps” to defi ne extent of previous resections, length of remaining bowel, and degree of previous mobilization of fl exures. Preoperative mechanical and antibiotic bowel preparation consists of 45 cc sodium phosphate solution (Fleets phosphosoda; C.B. Fleet Co., Inc., Lynchburg, VA) PO at 4 pm and at 9 pm, each fol­lowed by 3–8 oz glasses of water, and 1 gm neomy­cin with 500 mg metronidazole at 7:00 and 11:00 pm. In addition, 2 gm of cefotetan are adminis­tered intravenously and 5000 units of heparin injected subcutaneously at the start of the operation.

PITFALLS AND DANGER POINTS

Injury to liver, duodenum, or contents of the hepa­toduodenal ligament
Hemorrhage from epigastric, mesenteric, iliac, or gonadal vessels
Inadvertent enterotomy or colotomy
Inadvertent retrorenal dissection
Anastomotic insuffi ciency or twist

OPERATIVE STRATEGY

Elective laparoscopic right hemicolectomy is per­formed in a laparoscopic-assisted fashion with intra­corporeal mobilization of the ileum, cecum, and hepatic fl exure medially to the level of the duode­num and middle colic vessels. The bowel is then exteriorized through a small midline port incision extended to approximately 4 cm. Extracorporeal division of the mesentery is followed by resection of bowel and creation of a side-to-side functional end­to-end ileocolic anastomosis. The bowel is returned to the abdomen and re-insuffl ation allows fi nal inspec­tion of the intraperitoneal contents.
For patients with primary or recurrent Crohn’s ileitis, signifi cant infl ammation and adhesions may be encountered. Dissection is initiated in areas free of infl ammation to identify appropriate planes. Thor­ough inspection of the small bowel from the ileoce­cal valve to the jejunoduodenal junction using a two-instrument technique is essential to assess syn­chronous locations of disease which are addressed after maximal mobilization is accomplished laparo­scopically. Resections, anastomoses, enterotomy repairs, and stricturoplasties are most easily per­formed extracorporeally through a limited incision, preferably midline to preserve future potential ostomy sites.

Room Setup and Trocar Placemen

lower extremities in padded stirrups placed low for unimpeded movement of the instruments. Both arms are tucked at the patient’s sides and extra care is
aken to secure the patient to the bed because of the
otation and tilt required during surgery. A minimum of two monitors is needed and are placed one on each side of the patient at the head of the bed 3 –1). Bilateral ureteral stents are placed by a urolo
ist, followed by insertion of a urinary catheter and

ed with povodine-iodine solution, and appro
priately draped.
For port placement, the assistant stands to the right of the patient while the surgeon stays to the left. Three to four 10 mm trocars are employed for most procedures (Fig. 3 –2a and 3 –2b) Initially, a
0 mm trocar is placed by the open Hasson tech­nique in the supraumbilical position through which the camera is inserted. In the reoperative abdomen, the initial trocar can be placed in the left upper quadrant in a site remote from scars. The abdomen is insuf

ory bowel disease mandates advanced laparoscopic skills and may necessitate conversion to laparotomy. Thorough inspection of the small bowel from the
leocecal valve to the jejunoduodenal junction using a two-instrument technique is essential to assess anatomy and identify pathology. Any synchronous

Mobilization of the Cecu

etracted medially using Babcock clamps placed
hrough the left upper port. With the 10-mm ultra sonic shears placed through the left lower port, the peritoneum along the base of the terminal ileum mesentery and around the cecum is opened expos-

mately 4 cm midline incision. A plastic, impervious wound drape is placed, the cecum is gently grasped, and the right colon is easily delivered through the wound (Fig. 3 – 6) Points of tran
leum and colon are chosen and marked. The mesen-
ery between these points is clamped, ligated, and divided prior to bowel resection to prevent twisting of the bowel and mesentery. Once the mesentery is divided, closure of the mesenteric defect with absorb-
le suture is begun but left untied. Linear cutting
a staplers are used to divide the ileum and transverse colon and, subsequently, to perform the side-to-side
