Ten Versus Fifteen Centimeter Pouch in IPAA Surgery (TESTIMONY)

July 4, 2025 updated by: Odense University Hospital

Ileal Reservoir Length and Functional Outcome in Ileal Pouch-anal Anastomosis

The aim of this randomized controlled trial is to compare outcome after construction of an ileal (J-shaped) reservoir of 10 versus 15 centimeters in primary ileal pouch-anal anastomosis surgery.

Study Overview

Detailed Description

The primary aim of this randomized controlled trial is to compare functional outcome in terms of bowel function correlated with quality of life for patients who undergo primary ileal pouch-anal anastomosis surgery with an ileal (J-shaped) reservoir length of either 10 cm or 15 cm.

Secondary aims include health-related quality of life measures and postoperative complications.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pouch dysfunction score
Time Frame: 1, 3, 5 and 10 years after surgery
Ranges from 0 to 7.5, where a low score indicates good bowel function will little to no impact on quality of life
1, 3, 5 and 10 years after surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Short Inflammatory Bowel Disease Questionnaire
Time Frame: 1, 3, 5 and 10 years after surgery
Consists of 10 questions with a total score range from 10 (poor health-related quality of life) to 70 (good health-related quality of life)
1, 3, 5 and 10 years after surgery
Short-form (SF)-36
Time Frame: 1, 3, 5 and 10 years after surgery
Consists of questions relating to 8 domains of life with a total score ranging from 0-100, with lower numbers indicating worse health status
1, 3, 5 and 10 years after surgery
Postoperative complications using the Comprehensive Complication Index (CCI)
Time Frame: 90 days after surgery
The CCI is a continuous scale, where each postoperative complication as defined by Clavien-Dindo is assigned a weigth based on its severity. A total summarized score taking all complications into account is thus generated.
90 days after surgery
Pouch failure
Time Frame: 1, 3, 5 and 10 years after surgery
Hazard ratio of pouch failure defined as an intended permanent ileostomy with or without pouch excision
1, 3, 5 and 10 years after surgery
