Intestinal obstruction in patients with previous laparotomy for non-malignancy.

Abstract

BACKGROUND:

Intestinal obstruction is one of the most common surgical emergencies. The aim of this study was to identify important management information from the evaluation of patients with intestinal obstruction who had undergone previous laparotomy for non-malignancy.

METHODS:

Data from 176 patients with previous laparotomy for non-malignancy, and who were operated on for intestinal obstruction, were collected and analyzed retrospectively.

RESULTS:

Gastroduodenal operations, appendectomy, and obstetric/gynecologic procedures were the 3 most common previous abdominal surgeries. More than half of all bowel obstructions developed within 10 years after previous laparotomy, and particularly within the first 5 years. Most obstructions were related to adhesion, although their etiologies were diverse. The rate of bowel strangulation was much higher in patients with internal herniation, volvulus, intussusception, closed loop, and diaphragmatic hernia than in patients with simple adhesion, bezoar, tumor, and inflammation (48.3% vs 12.2%). The surgical mortality rate correlated significantly with bowel strangulation: the overall rate was 6.8%, that in patients with strangulation was 18.8%, and that in patients without strangulation was 4.2%.

CONCLUSION:

The etiologies of intestinal obstruction were not only significantly related to bowel strangulation, but were also an important determinant of therapeutic strategy.
