Is fecal diversion necessary during ileal pouch creation after initial subtotal colectomy in pediatric ulcerative...

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Colorectal Surgery

Background:

• Medically refractory ulcerative colitis (UC) in children often requires subtotal colectomy with end ileostomy (STC-I).
• The necessity of fecal diversion during subsequent completion proctectomy/ileal-pouch anal anastomosis (CP-IPAA) is debated.
• This study investigates the impact of fecal diversion in pediatric UC patients undergoing CP-IPAA.

Purpose of the Study:

• To compare the outcomes of diverted versus undiverted CP-IPAA in pediatric UC patients.
• To evaluate short-term complications and long-term functional results.
• To inform patient selection and counseling for CP-IPAA procedures.

Main Methods:

• A multi-institutional retrospective review of pediatric UC patients who underwent STC-I followed by CP-IPAA between 2008 and 2016.
• Patients were categorized into diverted (n=20) and undiverted (n=17) groups.
• Outcomes analyzed included length of stay, 30-day complication rates, anastomotic leaks, readmissions, reoperations, and long-term functional pouch outcomes.

Main Results:

• The undiverted CP-IPAA group experienced a significantly longer length of stay (9 days vs. 6 days, p=0.002).
• The 30-day complication rate was significantly higher in the undiverted group (p=0.003).
• No significant differences were observed in anastomotic leak, readmission, CT use, reoperation rates, or long-term functional pouch outcomes. Three undiverted patients required perioperative fecal diversion.

Conclusions:

• Undiverted CP-IPAA in pediatric UC patients is associated with increased immediate postoperative complications compared to diverted CP-IPAA.
• These short-term complications did not lead to significant long-term differences in functional pouch outcomes.
• Careful patient selection and counseling are crucial for undiverted pouch procedures in this population.
