Laparoscopically assisted subtotal colectomy for slow-transit constipation

Abstract

Background: When medical therapy fails, slow-transit constipation (STC), a condition seen almost exclusively in women, can be treated surgically. The aim of this study was to describe our results with laparoscopically assisted subtotal colectomy (LASC) for STC. Methods: Over a 22-month period, four female patients underwent LASC with ileorectal anastomosis for STC at our hospital. The preoperative workup included clinical assessment, evacuation proctography, rectoanal manometry, and colonic transit measurement. Mobilization of the whole colon and ligation and division of colonic mesenteric vessels with preservation of the omentum were achieved laparoscopically. Through a small Pfannenstiel incision, the colon was removed from the abdomen, leaving a 15-cm rectal stump in situ. The rectal stump was fully mobilized posteriorly, a side-to-end ileorectal anastomosis was fashioned, and the rectal stump was fixed onto the presacral fascia with sutures. Results: The operating time ranged from 150 to 260 min and blood loss was minimal. There were no conversions to open surgery. The postoperative course was uneventful in all patients but one, a 47-year old woman who had transient severe abdominal distension, pain, and frequent small-volume bowel movements. All patients were discharged by the 4th to 10th postoperative day. At 9-month follow-up, all of our patients had normal anorectal function with two to four solid bowel movements per day. Conclusion: Although it is a technically demanding procedure, laparoscopically assisted colectomy for slow-transit constipation, can be achieved safely.
