Application of intracorporeal anastomosis is gradually becoming widespread; however, there are no detailed reports on its configuration. We aimed to create three-dimensional intracorporeal anastomosis models and compare their configurations in detail.
Three types of intracorporeal anastomosis models were used: overlap anastomosis, delta-shaped anastomosis, and functional end-to-end anastomosis. In experiment 1, three-dimensional images of each anastomosis model were created. Additionally, the length of each staple line comprising the anastomotic site was measured. In experiment 2, the lengths of intestinal mobilization required for different anastomoses were compared.
The circumference of the anastomosis in overlap anastomosis (141.5 ± 3.3 mm) was significantly greater than that in delta-shaped anastomosis (87.9 ± 0.9 mm; p < 0.001) and functional end-to-end anastomosis (89.6 ± 10 mm; p < 0.0001). The length of the intestinal tract after anastomosis in delta-shaped anastomosis (33 ± 6.9 mm) was significantly shorter than that in functional end-to-end anastomosis (76 ± 2 mm; p < 0.0001) and overlap anastomosis (60 ± 5 mm; p < 0.002).
We successfully constructed three-dimensional images of intracorporeal anastomosis models. These results suggest that overlap anastomosis led to the formation of the largest anastomotic site, while minimal bowel mobilization was required in the delta-shaped anastomosis.
体内吻合术的应用正逐渐广泛；然而，关于其结构尚无详细报道。我们旨在创建三维体内吻合模型并详细比较它们的结构。
使用三种类型的体内吻合模型：重叠吻合、三角形吻合和功能性端端吻合。在实验1中，创建了每个吻合模型的三维图像。此外，测量了构成吻合部位的每条钉合线的长度。在实验2中，比较了不同吻合所需的肠管游离长度。
重叠吻合的吻合口周长（141.5±3.3毫米）显著大于三角形吻合（87.9±0.9毫米；p<0.001）和功能性端端吻合（89.6±10毫米；p<0.0001）。三角形吻合术后肠管长度（33±6.9毫米）显著短于功能性端端吻合（76±2毫米；p<0.0001）和重叠吻合（60±5毫米；p<0.002）。
我们成功构建了体内吻合模型的三维图像。这些结果表明，重叠吻合导致形成最大的吻合部位，而三角形吻合所需的肠管游离最少。
