Laparoscopic re-exploration in mechanical bowel obstruction after laparoscopic gastric bypass for morbid obesità

Aim:
This study reports a series of 7 patients who experienced small-bowel obstruction (SBO) after laparoscopic gastric bypass (LGBP).
Methods:
Between July 2001 and June 2004, 211 patients underwent surgery for morbid obesity in 2 different institutions and 7 of them required reoperative laparoscopic surgery or laparotomy for mechanical SBO.
Results:
Seven patients in the series (3%) developed a postoperative bowel obstruction requiring operative management. Their mean body mass index was 49 (range: 38-65) and the average age was 48 years (range 29-60). Six (86%) had undergone an initial LGBP. One (14%) had been converted to open surgery because of the presence of thick adhesions. One percent of the patients (14%) had undergone abdominal surgery prior to gastric bypass. The most common cause of SBO was internal hernia through a mesenteric defect (57%), followed by adhesions (14%), obstruction at the entero-enterostomy (14%) and Petersen hernia (14%). The obstruction was managed laparoscopically. Small-bowel resection was required in 14% with no death encountered after the second revision of the entero-enterostomy. Recovery time was less than 72 h after laparoscopic approach and more than 92 h following the open procedure.
Conclusions:
Laparoscopic surgical correction of SBO following LGBP in morbidly obese patients is feasible. Reoperation of morbidly obese patients after LGBP can be achieved successfully through laparoscopic techniques.
