Colectomy and endorectal ileal pull-through with lateral ileal reservoir for ulcerative colitis and polyposis in
Insights
Pediatric patients with severe ulcerative colitis or polyposis achieved good functional outcomes after ileal pull-through surgery with ileal reservoir construction. This surgical approach offers effective continence and improved quality of life for young patients.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Colorectal Surgery
Background:
- Chronic ulcerative colitis and multiple polyposis can significantly impact quality of life in children.
- Medical therapy is often refractory in severe pediatric cases, necessitating surgical intervention.
Purpose of the Study:
- To evaluate the efficacy and outcomes of total colectomy with endorectal ileal pull-through and ileal reservoir construction in pediatric patients.
- To assess functional results, including continence and stool frequency, after this complex reconstructive surgery.
Main Methods:
- Nineteen children with chronic ulcerative colitis and one with multiple polyposis underwent total colectomy, mucosal proctectomy, and endorectal ileal pull-through with ileoanal anastomosis.
- Seventeen patients subsequently had a second-stage closure of ileostomy with side-to-side isoperistaltic ileal reservoir construction.
- Anastomosis and reservoir placement details were recorded, along with complication rates and functional outcomes.
Main Results:
- Fourteen of 17 children with lateral reservoir construction achieved good-to-excellent results with complete continence and an average of five stools per 24 hours at 6 months.
- Transient reservoir inflammation occurred in over half of patients but improved with Metronidazole.
- Complications included one cuff abscess and two cases of ileal obstruction below the reservoir.
Conclusions:
- Total colectomy with endorectal ileal pull-through and ileal reservoir construction is a viable surgical option for pediatric patients with refractory ulcerative colitis or polyposis.
- The procedure can lead to good functional outcomes, including continence, and allows for participation in activities like competitive athletics.
- Careful consideration of reservoir-to-anal anastomosis distance is important to minimize obstruction complications.
Abstract:
Nineteen children with chronic ulcerative colitis refractory to medical therapy and one with multiple polyposis, all under 20 years of age, underwent total colectomy, mucosal proctectomy, and endorectal ileal pull-through with ileoanal anastomosis at the UCLA Medical Center during a 4 1/2-year period (mean age, 14.4 years). Seventeen patients underwent second-stage closure of the ileostomy with construction of a side-to-side isoperistaltic ileal reservoir (mean, 6 months) after the ileal pull-through operation. The anastomosis extended over a 20- to 30-cm distance and the lower end was placed within 6 to 8 cm of the ileoanal anastomosis. Transient reservoir inflammation, which occurred in more than half of the patients, was reduced by the use of oral Metranidazole and was rare 6 months postoperation. Cuff abscess in one patient did not respond to long-term antibiotics and required ileostomy as well as eventual takedown of the reservoir. Two patients developed obstruction of the ileum below the reservoir due to an extended distance between the reservoir and anal anastomosis, requiring transient ileostomy. Fourteen of the 17 children who have undergone lateral reservoir construction have achieved a good-to-excellent result, with complete continence and an average of five stools per 24 hours after 6 months. Seven of the 14 now participate in competitive athletics. Three children await construction of the reservoir.
