Development of a Specialist Ileoanal Pouch Surgery Pathway: a Multidisciplinary Patient-centred Approach

Background: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the gold standard procedure for ulcerative colitis refractory to medical treatment, as an alternative to permanent end ileostomy. Gaining experience in pouch surgery is difficult as the procedure is performed infrequently. This study presents an institutional initiative to promote standardisation of multidisciplinary care in IPAA surgery.

Methods: A dedicated pathway for patients who had an IPAA or are considering IPAA surgery was developed among colorectal surgeons, gastroenterologists, paediatric colorectal surgeons, inflammatory bowel disease (IBD) nurses, dietitians, stoma nurses, trainees in colorectal surgery. Pathway items were discussed and finalised via emails and videoconferences.The pathway included triaging of patients referred for IPAA surgery, preoperative IBD multidisciplinary team discussion and management plan for surgery, surgical review prior to surgery, peer to peer counselling, surgical technique, postoperative short-term and long-term follow-up, audit, research and training in IPAA surgery.

Results: A multidisciplinary preoperative pathway was developed and a stepwise approach to minimally invasive ileoanal pouch surgery was formalised. A dedicated one-stop ileoanal pouch clinic was established integrating endoscopy and imaging on the same day of the consultation with the surgical and gastroenterology team. The clinic reviewed 72 patients over 24 months, and during the same time 36 patients underwent IPAA surgery at our institution.

Conclusions: We have described our initial experience in establishing a specialist IPAA surgery pathway and have proposed outcome measures that we hope will support a subspecialty IPAA service.
