Abstract

Objective: The aim of the study was to evaluate time to closure, bursting pressures and luminal diameters of a single and double-layer end-to-end anastomoses in normal equine descending colon.

Study design: Experimental study.

Sample population: Eight adult horses.

Methods: Four segments of descending colon from each horse were randomly assigned to a control (n = 8, CON), one-layer (n = 12, group 1; continuous Lembert pattern), or two-layer group (n = 12, group 2; simple continuous oversewn with Cushing pattern). Anastomoses were performed, and time to closure and luminal diameter were measured. Bursting pressures were determined, and location of failure was recorded. Mixed analysis of variance (ANOVA) was employed.

Results: Mean time to completion was decreased (p = .003) in group 1 (18.6 min ± 22.8 s) compared with group 2 (21.35 min ± 22.8 s). Luminal diameter was reduced (p < .0001) in group 2 (47 ± 2.46 mm) compared to group 1 (65 ± 2.77 mm). Location of failure was remote to the anastomosis in all but one segment; therefore, differences in anastomotic bursting pressures could not be determined.

Conclusion: Two-layer closures resulted in significant luminal reduction and took longer to complete than one-layer anastomoses.

Clinical significance: Use of one-layer closures may be advantageous primarily with respect to luminal diameter.

正常马降结肠端端吻合单层与双层闭合的体内外比较

研究目的研究旨在评估正常马降结肠中单层和双层端端吻合器的闭合时间、爆破压力和管腔直径：研究设计：实验研究：八匹成年马：每匹马的四段降结肠被随机分配到对照组（n = 8，CON）、单层组（n = 12，第 1 组；连续 Lembert 模式）或双层组（n = 12，第 2 组；带有 Cushing 模式的简单连续套结）。进行吻合，测量闭合时间和管腔直径。确定爆破压力并记录破裂位置。采用混合方差分析（ANOVA）：结果：与第 2 组（21.35 分钟 ± 22.8 秒）相比，第 1 组（18.6 分钟 ± 22.8 秒）的平均闭合时间缩短（p = .003）。管腔直径减小（p = 0.003）：与单层吻合相比，两层闭合会导致管腔明显缩小，完成时间更长：临床意义：使用单层吻合器可能主要在管腔直径方面具有优势。

期刊介绍： Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations. It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
