背景关于胃肠道吻合术中最佳钉钉方向的研究很少。本研究的目的是评估吻合器发射方向对吻合口破裂压力的影响。方法所有实验均采用pig食管和小肠。小肠代表薄的肠道，食道代表厚的肠道。使用线性吻合器进行侧对侧吻合，并测量破裂压力。然后对吻合口进行泄漏试验，并测量破裂压力。结果使用GIA™100-3.8吻合术后的破裂压力为47.4±10.4 mm Hg，使用相同GIA吻合术时，将钉钉从小肠推入食管时的破裂压力明显更大（83.3±17.3 mm Hg）。使用GIA™100-4.8，我们发现吻合器进入小肠时的破裂压力明显大于进入食管时的破裂压力（51.6±7.1比68.6±16.1 mm Hg）。在同一方向上发射时，不同gia之间没有显著差异。结论吻合器从小肠推入食管时，破裂压力明显增大。钉线的方向影响吻合的强度。
BackgroundFew studies have been conducted regarding the optimal staple direction in gastrointestinal anastomosis. The purpose of this study was to evaluate the burst pressure of the anastomosis depending on the firing direction of the stapler.MethodsPig esophagus and small bowel were used for all experiments. The small intestine represented a thin intestinal tract and the esophagus represented a thick intestinal tract. A side-to-side anastomosis was performed using a linear stapler, and the burst pressure was measured. A leak test on the anastomosis was then performed and burst pressures measured.ResultsBurst pressures after anastomosis using a GIA™ 100-3.8 were 47.4±10.4 mm Hg. With the same GIA, the burst pressure was significantly greater when the staples were driven from the small intestine into the esophagus (83.3±17.3 mm Hg). Using the GIA™ 100-4.8, it was found that the burst pressure was significantly greater when the staplers were driven into the small intestine versus the esophagus (51.6±7.1 vs. 68.6±16.1 mm Hg). There was no significant difference between the different GIAs when fired in the same direction.ConclusionBurst pressures were significantly greater when the staplers were driven from the small intestine into the esophagus. The direction of the staple line influences the strength of the anastomosis.
