��еконструкция прямой кишки после тотальной мезоректумэктомии: функциональные результаты и качество жизни

Background . The study aims to compare the functional outcomes and quality of life in patients having variant rectal reconstruction procedures after low anterior resection for cancer. Materials and methods . A prospective randomised controlled trial enrolled 90 patients who underwent total mesorectumectomy with formation of J-pouch (J-P), side-to-end (STE) or end-to-end (ETE) anastomoses. Results and discussion . We analysed 22 J-P, 30 STE and 38 ETE patients. For technical reasons, 26.6 % J-Ps were remodelled to other anastomoses. The neorectal sensory threshold, first and permanent defecation urges and maximal tolerated volume were higher in J-P at months 3–6–12 postoperatively. Severe low anterior resection syndrome events at post-surgery month 6 were significantly more frequent in the ETE vs. J-P and STE cohorts (21, 0 and 3.3 %, respectively, p 0.05). Evacuatory dysfunction was present at month 6 in 59.1 J-P, 33.3 STE and 21.1 % ETE. Quality of life (FIQL) in J-P and STE was significantly higher vs. ETE anastomoses in the Lifestyle (3.21, 3.22 and 3.03, respectively, p < 0.05) and Coping (3.29, 3.21 and 2.95, respectively, p < 0.05) scales to month 12 postoperatively. Conclusion . The J-pouch formation after low anterior resection ameliorates anal continence at months 3–6 post-surgery, reduces low anterior resection syndrome and improves quality of life (FIQL). The ease of implementation and irrelevance of evacuatory dysfunction in side-to-end anastomosis make it a superior choice over end-to-end surgery.
