[Comparison of colorectal mechanical suture techniques].

Unlabelled: Objective of this study is to establish which kind of stapled anastomosis is the most reliable in rectal surgery. 67 patients randomly assigned to three groups underwent low anterior resection of the rectum with end-to-end, side-to-end or double stapling anastomosis. Main outcome measures were incidence of leakage at the intraoperative check of the suture, postoperative leakage, stenosis, mortality, mean post-operative stay. Side-to-end anastomosis were followed by 4 intra-operative (19%) and one post-operative (4.7%) leakages with one case of mortality (4.7%). Four intra-operative (18.2%) and 5 post-operative (22.7%) leakages, 3 stenosis (13.6%) and one case of mortality (4.5%) were observed after double-stapling procedures. No intra- or post-operative anastomotic complications were seen after end-to-end anastomosis. Mean post-operative stay was 20, 31 and 13 days for the three methods respectively.

Conclusions: In this series of colo-rectal anastomoses, the end-to-end stapling technique appears to be safer and more reliable than others.
