Large bowel repair
Defects in the serosa and small lacerations can be managed with a primary closure, similar to the small intestine. For more extensive injuries that may require resection, diversion, or complicated repair, consultation with a gynecologic oncologist or general or colorectal surgeon may be indicated as colotomy repairs are associated with higher rates of breakdown and fistula. If fecal contamination is present, copious irrigation should be performed and placement of a peritoneal drain to reduce the likelihood of abscess formation should be considered. If appropriate antibiotic prophylaxis for colonic surgery has not been given prior to skin incision, it should be administered once the colotomy is identified.
Standard prophylaxis for hysterectomy (such as a first-generation cephalosporin like cefazolin) is not adequate for large bowel surgery, and either metronidazole should be added or a second-generation cephalosporin such as cefoxitin should be given. For patients with penicillin allergy, clindamycin or vancomycin with either gentamicin or a fluoroquinolone should be administered.6
Postoperative management
The potential for postoperative morbidity must be understood for appropriate management following bowel surgery. Ileus is common and the clinician should understand how to diagnose and manage it. Additionally, intra-abdominal abscess, anastomotic leak, fistula formation, and mechanical obstruction are complications that may require surgical intervention and must be vigilantly managed.
The routine use of postoperative nasogastric tube (NGT) does not hasten return of bowel function or prevent leak from sites of gastrointestinal repair. In fact, early feeding has been associated with reduced perioperative complications and earlier return of bowel function has been observed without the use of NGT.7 In general, for small and large intestinal injuries, early feeding is considered acceptable.8
Prolonged antibiotic prophylaxis, beyond 24 hours, is not recommended.6
Avoiding injury
Gynecologic surgeons should adhere to surgical principles with sharp dissection for adhesions, gentle tissue handling, adequate exposure, and light retraction to prevent bowel injury or minimize their extent. Laparoscopic entry sites should be chosen based on the likelihood of abdominal adhesions. When the patient’s history predicts a high likelihood of intraperitoneal adhesions, the left upper quadrant site should be strongly considered as the entry site. The likelihood of gastrointestinal injury is not influenced by open versus closed laparoscopic entry and surgeons should use the technique with which they have the greatest experience and skill.9 However, in patients who have had prior laparotomies, there is an increased risk of periumbilical adhesions, and consideration should be made for a nonumbilical entry site.10 Methodical sharp dissection and sparing use of thermal energy should be used with adhesiolysis. When injury occurs, prompt recognition, preparation, and methodical management can mitigate the impact.
