The aim of this study is to compare handsewn and stapled jejunocecal anastomosis with different stomal lengths in terms of anatomical differences. Group 1 underwent a two-layer handsewn jejunocecal side-to-side anastomosis (HS); Group 2 received a stapled jejunocecal side-to-side anastomosis (GIA). Each group was divided into two subgroups (HS80 and HS100, GIA80 and GIA100). Specimens were inflated and CT scanned. The stomal/jejunal area ratio and blind end pouch volume/area were measured and compared. Effective length of the stoma was measured and compared with the initial length. Stomal/jejunal area ratio was 1.1 for both 80 techniques, 1.6 for the GIA100, and 1.9 for the HS100 technique. Both HS and GIA techniques produced a blind end pouch and exhibited a mean increase of the final stomal length ranging from 6 to 11% greater than the original stomal length. All techniques will exhibit a length increase of the final stomal length compared to the intended stomal length, with a consequent increase in stomal area. Stapled techniques consistently produced a large distal blind end pouch. Length of a jejunocecal anastomosis should be selected in accordance with the diameter of afferent jejunum, and the 80 mm stomal length could be deemed sufficient in horses.
本研究旨在比较不同吻合口长度的手工缝合和吻合器缝合空肠回肠吻合术在解剖学差异方面的情况。第1组接受两层手工缝合的空肠回肠侧侧吻合术（HS）；第2组接受吻合器缝合的空肠回肠侧侧吻合术（GIA）。每组再分为两个亚组（HS80和HS100，GIA80和GIA100）。对标本进行充气并进行CT扫描。测量并比较吻合口/空肠面积比以及盲端袋体积/面积。测量吻合口的有效长度并与初始长度进行比较。80技术的两种吻合口/空肠面积比均为1.1，GIA100为1.6，HS100技术为1.9。HS和GIA技术均产生了盲端袋，且最终吻合口长度平均增加幅度比原始吻合口长度大6%至11%。与预期吻合口长度相比，所有技术的最终吻合口长度均会增加，从而导致吻合口面积增加。吻合器技术始终会产生较大的远端盲端袋。空肠回肠吻合术的长度应根据输入袢空肠的直径来选择，80毫米的吻合口长度在马匹中可认为是足够的。
