A right colon pouch with a novel efferent channel concept: long-term results of the Turin pouch

Purpose: To report stoma stenosis rates and efferent channel (EC) complications at long term follow-up for Turin pouch (TP). Methods: This is a retrospective analysis of the prospectively maintained database of patients who underwent TP between March 2006 and May 2018. The TP is a U-shaped right colon pouch. The EC was conceived by the tubularization of 5 cm of the colon wall with the use of a stapler and sutured to the skin (EC-cutaneostomy). The ureters are sutured separately to the last 10 cm of ileum before the ileocecal valve. In literature, catheterization problems have been described on average in 20.3% of patients and stoma stenosis in 19.5% of the patients with flap valve systems. Results: Thirty-eight consecutive patients underwent a TP procedure. The median age was 55 years (IQR: 52–60). Median operative time was 201 min (IQR: 170–210), median reconstructive time was 61 min (IQR: 55–65) and the blood loss was 244 ml (IQR: 150–300) and 4 patients (10.5%) needed blood transfusions. The median follow-up was 52 months (IQR: 37–92). Complete 24h continence was achieved in 34 (89%) patients. Seven (18.4%) patients reported difficulties in EC catheterization and 4 (10.5%) patients had stoma stenosis. This study is limited by the relatively small number of patients. Conclusion: In relation to similar systems, the TP seems to offer comparatively good functional results but EC and stoma complications were lower than other pouch variants in literature.
