A reconstructive operation on malfunctioning S-shaped pelvic reservoirs

Area of Science:

• Gastroenterology
• Surgical Innovation
• Pelvic Reservoir Management

Background:

• Triple-loop pelvic reservoirs can cause significant evacuation problems, including need for intubation, frequent stooling, leakage, and ileoanal disruptions.
• Previous studies identified reservoir malposition and a long, kinked efferent limb as primary causes of these complications.

Purpose of the Study:

• To design and evaluate a corrective surgical procedure aimed at improving pelvic reservoir topography and resolving associated evacuation issues.
• To assess the efficacy of this corrective surgery in patients with previously failed pelvic reservoir reconstructions.

Main Methods:

• A novel corrective operation was developed involving complete mobilization of the pouch and efferent conduit.
• The efferent limb was significantly shortened, and the reservoir was repositioned closer to the anus.
• The ileoanal anastomosis was reestablished in seven patients who had previously experienced "failure" with their reservoirs.

Main Results:

• The corrective surgery yielded gratifying results in the seven treated patients.
• Six patients achieved efficient bowel evacuation post-operatively.
• Four patients experienced complete resolution of leakage after the corrective procedure.

Conclusions:

• The corrective surgery effectively resolves evacuation problems associated with triple-loop pelvic reservoirs.
• Optimizing reservoir topography through surgical revision is strongly correlated with improved clinical outcomes.
• This approach offers a viable solution for patients with complex pelvic reservoir complications.
