Abstract

Background: An intracorporeal anastomosis for colorectal resections has several advantages over a traditional extracorporeal anastomosis. A double stapled intracorporeal anastomosis compared to a single-stapled technique could reduce operative time and increase uptake of this beneficial technique. However, the patency and calibre of this anastomosis require laboratory assessment.

Objective: The aim of the study was to assess and compare the luminal diameter and patency of the double-stapled (intracorporeal type) anastomosis (DICA) with a single-stapled (intracorporeal type) anastomosis (SICA) and a double-stapled (extra-corporeal type) anastomosis (ECA).

Methods: Experimental laboratory-based study using fresh bovine intestine. Construction and assessment of two of each of the following anastomotic types: DICA, SICA, and ECA. The primary outcome measure was the luminal diameter of the anastomosis, comparing the ratios of the narrowest point of the anastomosis to the narrowest luminal diameter. Secondary outcome tests were leak and patency testing for each anastomosis.

Results: All six anastomoses were found to be patent and without any anastomotic leakage. The ratio of narrowest anastomotic diameter to narrowest luminal diameter for all three anastomoses was comparable (extracorporeal anastomosis 1.16, single-stapled intracorporeal anastomosis 1.0 and double-stapled intracorporeal anastomosis 0.97).

Conclusion: This study confirms the in vitro patency and the adequacy of luminal diameter of the double stapled (intracorporeal type) anastomosis.

腹腔镜右半结肠切除术中吻合口形态的实验室评价。
背景:与传统的体外吻合术相比,体外吻合术在结肠直肠切除术中的应用具有许多优点。与单吻合术相比,双吻合术可以减少手术时间,增加对这种有益技术的吸收。然而,这种吻合的通畅度和口径需要实验室评估。目的:评价和比较双吻合器(体内型)吻合(DICA)与单吻合器(体内型)吻合(SICA)和双吻合器(体外型)吻合(ECA)的腔径和通畅性。方法:以新鲜牛肠为实验材料进行实验室研究。DICA、SICA和ECA三种吻合类型各两种的构建和评估。主要观察指标为吻合口的管腔直径,比较吻合口最窄点与最窄管腔直径的比值。次要结局试验为每个吻合口的泄漏和通畅试验。结果:6例吻合口均通畅,无吻合口瘘。三种吻合口最窄直径与腔内最窄直径之比具有可比性(体外吻合1.16,单吻合器内吻合1.0,双吻合器内吻合0.97)。结论:本研究证实了体外双吻合器(体内型)吻合的通畅性和腔径的充分性。
