AIM: Enterocele is common among patients suffering from obstructive defecation syndrome (ODS), but it is often considered a contraindication for stapled transanal surgery. The functional results and complication rates were compared in patients with or without enterocele who were treated with stapled transanal rectal resection (STARR) for ODS.

METHOD: Patients presenting with ODS were evaluated using standardized clinical and radiological investigations. A total of 170 patients were treated with either PPH01-STARR or Contour Transtar® and were followed up for a median of 18 months.

RESULTS: On preoperative defecography, 55 (32%) of 170 patients were found to have an enterocele. The preoperative Cleveland Clinic Constipation Scores (CCCS) in patients with and without enterocele were (mean ± standard deviation) 15.9 ± 5.4 and 15.4 ± 5.2, respectively. At 18 months postoperatively the CCCS were 8.5 ± 2.7 and 8.1 ± 2.6 (P < 0.001), respectively, in patients with and without enterocele. Morbidity was 7.3% (n = 4) in patients with enterocele (anal pain, n = 1; minor bleeding, n = 2; and acute urinary retention, n = 1) and 7.0% (n = 8) in patients without enterocele (anal pain, n = 3; minor bleeding, n = 3; acute urinary retention, n = 1; and staple line dehiscence, n = 1). There were no cases of pelvic sepsis, small bowel injury or postoperative ileus. No patient needed surgical re-operation.

CONCLUSION: There was no difference in functional outcome and postoperative complications in patients with and without enterocele undergoing STARR for ODS.
