Altering the Traditional Approach to Restorative Proctocolectomy After Subtotal Colectomy in Pediatric Patients.

ABSTRACT

Purpose: Restoration of intestinal continuity by ileal pouch-anal anastomosis (IPAA) following subtotal colectomy may not require a temporary, protective ileostomy. Diversion contributes to patient discomfort, cost, and additional operative risk at the time of subsequent reversal. We compared the outcomes of pediatric patients undergoing modified two-stage to three-stage IPAA after recovering from subtotal colectomy. Methods: We reviewed children (age <18) who underwent IPAA creation for ulcerative or indeterminate colitis from January 1, 2007 to December 31, 2017. Patient characteristics, operative details, 30-day complications, and postoperative length of stay (LOS) were abstracted. Total LOS for the three-stage group included both the IPAA and the ileostomy reversal operations. Univariate comparisons between patients undergoing modified two-stage and three-stage operations were performed. Results: A total of 43 patients underwent IPAA after subtotal colectomy; 32 (74%) underwent a three-stage approach, and 11 (26%) had a modified two-stage approach. Operative approach was laparoscopic in 33 (77%), planned open in 9 (21%), and converted to open in 1 (2%). Single-incision technique was used in 12 of 33 (36%) laparoscopic cases. Modified two-stage procedures had shorter total median LOS (7 days versus 9 days, P = .005). Incidence of postoperative leak, readmission, return to the operating room, and maximum 30-day Clavien-Dindo scores at the time of IPAA creation did not differ between modified two- and three-stage approaches (all P > .05). Conclusion: The modified two-stage approach to IPAA creation resulted in fewer hospital days compared to the three-stage approach. Considering the risks and patient burdens of diversion, further research is needed to assist in decisions regarding protective ileostomy after completion proctectomy with IPAA.
