A novel U-tied semi-manual anastomosis in totally laparoscopic colectomy

Abstract

TechniqueWe describe improvements to the previously proposed “U-tied anastomosis” with the aim of broadening its indications, especially in left hemicolectomy. After bowel mobilization and vascular ligation, the proximal and distal colon were aligned in a U-shape using a ligature. An anastomosis was constructed using a linear stapler through the common enterotomies. Following resection of the bowel using laparoscopic coagulation shears, the common opening was closed using 3-0 barbed sutures. ResultsEight consecutive patients underwent colectomy using the U-tied semi-manual technique between May and July 2023. In all cases, the U-tied procedures were completed using one cartridge and two sutures. No complications or mortality were observed after one month of follow-up. ConclusionsThe U-tied semi-manual anastomosis is a straightforward and effective method for intracorporeal anastomosis. The simplified reconstruction technique of U-tied series, together with the minimization of technique variability, results in consistent outcomes when performed by surgeons with different levels of experience. The streamlined process enhances the homogeneity of the intracorporeal anastomosis while reducing cartridge use.
