Postoperative Complications

Abstract

Patients undergoing extensive adhesiolysis are at highest risk for enterotomies. An enterotomy in and of itself is not a complication, rather it is the failure to recognize and adequately repair an enterotomy that leads to trouble. In cases in which any significant degree of adhesiolysis is performed, the entire bowel should be carefully inspected at the end of the procedure. Although the natural history of serosal tears is unknown, they should be repaired when recognized with imbricating seromuscular sutures. Full-thickness enterotomies can be repaired using a number of different and equally effective techniques. In cases in which multiple enterotomies have occurred within a short segment of bowel, resection of the involved segment with primary anastomosis is performed. If the mesentery has also been injured during the course of adhesiolysis, the viability of the bowel ends should be confirmed before anastomosis. Failure to recognize an enterotomy at the time of surgery will lead to one of several postoperative complications: The patient may develop peritonitis within the first 24–48 h after surgery. This may be difficult to detect in the background of narcotic analgesia and the surgeon and patient’s expectation of postoperative incisional pain. The diagnosis is purely based on patient appearance and examination. The usual markers of bowel perforation (leukocytosis, fever, and pneumoperitoneum) are not reliable, because they are normal findings in the early postoperative patient. A high index of suspicion should be maintained with a low threshold for reexploration. Reoperation within the first several days is usually not difficult because significant adhesions have not yet formed. Most enterotomies found in this situation can be repaired primarily, provided that the bowel edges are viable. Should the repair fail, if the repair can be placed directly under the midline fascial closure, this may result in the development of a direct enterocutaneous fistula rather than recurrent peritonitis. If conditions are not favorable for primary repair, a stoma should be created.
