Brief summary

This study aims to compare the functional and surgical outcomes of Ulcerative Colitis (UC) patients undergoing Transanal Transection and Singl-Stapled (TTSS) versus Double-stapled Ileal Pouch-Anal Anastomosis (IPAA)

Detailed description

Ileal Pouch-Anal Anastomosis (IPAAI in Ulcerative Colitis (UC) patients is usually performed by double-stapling technique after rectal transection with a linear stapler. Double-stapling is increasingly criticized for the uneven longer cuffs and potential weak points. The Transanal Transection and Single-Stapled (TTSS) approach may potentially overcome the limitations of double-stapling. A single-stapled anastomosis may be accomplished through a transanal rectal transection followed by bottom-up dissection (transanal-ileal pouch-anal anastomosis) or through an abdominal, rectal dissection and subsequent transanal transection and single-stapled anastomosis. TTSS-IPAA approach was shown to provide reduced rectal cuff length and reduced rate of urgency at six months after stoma closure. However, the retrospective and single-center features of these findings may prevent a robust conclusion about the superiority of TTSS-IPAA. The purpose of this study is to compare short-term and functional outcomes of double-stapling versus TTSS techniques for IPAA in UC patients in a prospective multicentric cohort study.

Design outcomes

Primary

MeasureTime frameDescription
Pouch Function Score (PFS)6 months after surgery or stoma closureMedian difference of the Pouch Function Score (PFS) \[score ranging from 0 (no pouch symptoms) to 30 (severe pouch symptoms)\] between the study cohorts

Secondary

MeasureTime frameDescription
Postoperative complications90 days after surgeryRate difference of postoperative complications, classified according to the Clavien-Dindo scale \[ranging from 0 (no complications) to 5 (complications leading to death)\] between the study cohorts
Anastomotic leak90 days after surgeryRate difference of anastotic leaks between the study cohorts
Patients fit for stoma closure12 months after surgeryProportion difference of patients fit for stoma closure in the study cohorts. Patients fit for stoma closure have already closed the stoma or have an intact anastomosis as demonstrated by a water contrast enema, Computed Tomography (CT) scan, endoscopic, or surgical revision
Pouch Function Score (PFS)12 months after surgery or stoma closureMedian difference of the Pouch Function Score (PFS) \[score ranging from 0 (no pouch symptoms) to 30 (severe pouch symptoms)\] between the study cohorts
Rectal cuff lenghtAt surgeryMedian difference of rectal cuff lenght (in cm) between the study cohorts
Pouch complications24 months after surgery or stoma closureIncidence rate difference of pouch complications or defunction- defined as any condition affecting the pouch function or requiring the pouch breakdown, including acute or chronic pouchitis, cuffitis, Crohn's disease of the pouch, or any other inflammatory condition - between the study cohorts.
Healthcare costs12 months after surgeryMedian difference of healthcare costs (direct and indirect) between the study cohorts
