Prevalence and mechanisms of small intestinal obstruction following laparoscopic abdominal surgery - A retrospective multicenter study

Hypothesis;: The prevalence and mechanisms of intestinal obstruction follow ing laparoscopic abdominal surgery have not been studied extensively. Design: Retrospective review of cases of intestinal obstruction after lapar oscopic surgery. Setting: Sixteen surgical units performing laparoscopy in France. Patients: Twenty-four patients with intestinal obstruction. Main Outcome Measures: Prevalence values and descriptive data. Results: The 3 most frequent primary procedures responsible for intestinal obstruction were cholecystectomy (10 cases), transperitoneal hernia repair (5 cases), and appendectomy (4 cases). Prevalences of early postoperative i ntestinal obstruction after these procedures were 0.11%, 2.5%, and 0.16%, r espectively. intestinal obstruction was due to adhesions or fibrotic bands in 12 cases and to intestinal incarceration in 11 cases. Obstruction was lo cated at the trocar site in 13 cases (9 incarcerations and 4 adhesions), ma inly at the umbilicus, and in the operative field in 10 cases(2 incarcerati ons in a wail defect after transperitoneal inguinal hernia repair, 4 adhesi ons, and 4 fibrotic bands). The small intestine was involved in 23 of 24 ca ses; the other was due to fecal volvulus following unrecognized intestinal malrotation. Intestinal obstruction was treated by laparoscopic adhesiolysi s in 6 patients and by laparotomy in 18 patients, 6 of whom required small intestine resection. Three postoperative complications but no deaths occurr ed. Conclusion: Intestinal obstruction following laparoscopic abdominal surgery can occur irrespective of the type of operation: the prevalence is as high as (cholecystectomy and appendectomy) or even higher than (transperitoneal hernia repair) that seen in open procedures.
