The outcome after restorative proctocolectomy with or without defunctioning ileostomy

Area of Science:

• Gastroenterology
• Surgical Oncology
• Colorectal Surgery

Background:

• Restorative proctocolectomy is a common procedure for ulcerative colitis and familial adenomatous polyposis.
• Diverting ileostomy is often used to reduce complications, but its routine omission is debated.

Purpose of the Study:

• To compare postoperative complications, functional outcomes, and quality of life in patients with and without a diverting ileostomy during restorative proctocolectomy.
• To assess the safety and efficacy of omitting diverting ileostomy in select patient cohorts.

Main Methods:

• Retrospective review of 1,725 patients with diverting ileostomy and 277 patients without (one-stage procedure).
• Criteria for ileostomy omission included stapled anastomosis, tension-free anastomosis, good hemostasis, and absence of malnutrition or steroid use.
• Functional outcomes and quality of life were prospectively assessed.

Main Results:

• No significant differences in septic complications or mortality between the ileostomy and one-stage groups.
• The one-stage group experienced more early postoperative ileus.
• Patients in the ileostomy group were older, had a larger body surface area, and required more blood transfusions.

Conclusions:

• Omission of diverting ileostomy is safe in carefully selected patients undergoing restorative proctocolectomy.
• Ileostomy omission does not increase septic complications or mortality.
• Quality of life and functional results are comparable between groups when appropriate selection criteria are met.
