Association between mucosectomy and endoscopic outcomes in patients with ileal pouch-anal anastomosis.

Background

In patients with inflammatory bowel disease (IBD) for whom medical therapy is unsuccessful or who develop colitis-associated neoplasia, restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is often indicated. One consideration for surgeons performing this procedure is whether to create this anastomosis using a stapled technique without mucosectomy or using a hand-sewn technique with mucosectomy. This study tested the association between IPAA anastomosis technique and cuffitis and/or pouchitis, assessed endoscopically.

Methods

This was a retrospective cohort study. We included consecutive adult patients with IBD who had undergone IPAA and had received index pouchoscopies at Columbia University Irving Medical Center between 2020 and 2022. Patients were then followed up from this index pouchoscopy for ≤12 months to a subsequent pouchoscopy. The primary exposure was mucosectomy vs non-mucosectomy and the primary outcome was cuffitis and/or pouchitis, defined as a Pouch Disease Activity Index endoscopy subscore of ≥1.

Results

There were 76 patients who met study criteria including 49 (64%) who had undergone mucosectomy and 27 (36%) who had not. Rates of cuffitis and/or pouchitis were 49% among those with mucosectomy vs 41% among those without mucosectomy (

Conclusions

There was no association between anastomosis technique and cuffitis and/or pouchitis among patients with IBD. These results may support the selection of stapled anastomosis over hand-sewn anastomosis with mucosectomy.
