Condition or disease | Intervention/treatment | Phase |
---|---|---|
Intestinal Volvulus Colon, Sigmoid | Procedure: Resection and anastomosis Procedure: Resection and colostomy Procedure: Mesosigmoidopexy | Not Applicable |
Participants: Patients 18 years or older presenting to Kamuzu Central Hospital in Lilongwe Malawi with sigmoid volvulus will be eligible for inclusion.
Procedures (methods): This is a prospective randomized trial. Subjects will be randomized during surgery to receive resection and anastomosis or mesosigmoidopexy (for non-gangrenous sigmoid volvulus), and resection and anastomosis or Hartmann's procedure (for gangrenous sigmoid volvulus).

Arm | Intervention/treatment |
---|---|
Active Comparator: G-SV Resection and colostomy
Gangrenous sigmoid volvulus patients randomized to undergo resection with colostomy and delayed anastomosis
|
Procedure: Resection and colostomy
Resection of sigmoid colon with end colostomy and Hartmann's pouch, followed at a later date by Hartmann's reversal as a second surgical procedure
|
Experimental: G-SV Resection and anastomosis
Gangrenous sigmoid volvulus subjects randomized to undergo resection and anastomosis
|
Procedure: Resection and anastomosis
Resection of sigmoid colon with primary anastomosis
|
Active Comparator: NG-SV resection and anastomosis
Nongangrenous sigmoid volvulus subjects randomized to undergo resection and anastomosis
|
Procedure: Resection and anastomosis
Resection of sigmoid colon with primary anastomosis
|
Experimental: NG-SV mesosigmoidopexy
Nongangrenous sigmoid volvulus subjects randomized to undergo mesosigmoidopexy
|
Procedure: Mesosigmoidopexy
Mesosigmoidopexy--the fixation of the sigmoid colon to lateral abdominal wall with concomitant shortening of the mesosigmoid length.

- Mortality [ Time Frame: 30-Day ]Mortality within 30 days of surgery, as determined by hospital inpatient records, outpatient clinical records and telephone contact (with next-of-kin)per study protocol.
- Recurrence of Sigmoid Volvulus [ Time Frame: 3 Year ]Recurrence of sigmoid volvulus confirmed radiologically or operatively within 3 years of surgery. This will be determined by hospital inpatient records, outpatient clinical records and telephone contact (with next-of-kin, and if recurrence diagnosed outside of study site contact with the treating physician) per study protocol.
- Surgical Site Infection [ Time Frame: 30-Day ]Surgical site infections as defined by the Centers for Disease Control within 30 days of surgery.
- Anastomotic Leak [ Time Frame: 30-Day ]Communication of the intraluminal and extraluminal space ad defined by clinical presence of a fecal fistula or operative determination of breakdown of the anastomosis within 30 days of surgery. Of note the NG-SV mesosigmoidopexy arm will not be included in this outcome as there is no anastomosis.
- Stomal Complications [ Time Frame: 3 Year ]Stomal complications (necrosis, pain, skin irritation, retraction, prolapse, stenosis, parastomal herniation, ventral hernia at prior stoma incision) within 3 years of surgery. Of note the G-SV Resection and colostomy arm will be the only arm included in this outcome as none of the other arms include a colostomy.
