Obstructive complications of laparoscopically created defunctioning ileostomy

The use of defunctioning ileostomy is a common practice to reduce the septic complications after anastomotic leakage in colorectal surgery. In open surgery, the fashioning of ileostomy is a straightforward procedure. However, in the laparoscopic approach, this can be a difficult task and obstructive complications can occur postoperatively.

A retrospective review was undertaken for all patients who underwent laparoscopic colorectal resection and defunctioning loop ileostomy over a 15-year period.

In this period, 161 patients underwent laparoscopic colorectal surgery with defunctioning ileostomy. Eight patients developed obstructive complications in the early postoperative period requiring surgical intervention (5 percent). All patients presented with intestinal obstruction from the fourth to the sixth postoperative day. The median time to reoperation was 9.5 days (range, 5 to 19). The causes of obstructive complications were twisting of the ileostomy (n = 3), adhesive kinking proximal to the ileostomy (n = 3), tight fascia (n = 1), and both tight fascia and twisting of ileostomy (n = 1). Six patients underwent laparotomy for diagnosis and refashioning of ileostomy. The seventh patient had endoscopic decompression of small bowel and refashioning of ileostomy. The last patient was successfully managed with combined endoscopic and laparoscopic approach.

Various pitfalls can occur in laparoscopically created defunctioning ileostomy. Measures can be taken to minimize these technical errors. Various surgical reinterventions can be attempted to determine the cause. With combined uses of enteroscope and laparoscope, a laparotomy can be avoided.
