A circular stapler introducer was developed to protect the head of the circular stapler and enable atraumatic introduction and advancement of the circular stapler without interfering with the application and safety of an anastomosis.
In a Phase I prospective study, we tested the feasibility and safety of the novel circular stapler introducer device in 60 consecutive patients undergoing left-sided colorectal resections.
The median distance of the anastomoses from the anal verge was 12 cm (7-20, n = 60). Total morbidity was 15 percent. No mortality was observed. Handling of the circular stapler introducer was considered nonproblematic by all surgeons who participated in the study. No interference of the circular stapler introducer with the circular stapling devices used was encountered. The advancement of the stapler into the end of the colorectal stump was always possible with the aid of the circular stapler introducer.
Use of the circular stapler introducer facilitates the double-stapling technique of colorectal anastomosis. The circular stapler introducer has great potential and should be tested in larger studies.
研发一种圆形吻合器导入器，以保护圆形吻合器头部，并能在不干扰吻合操作及安全性的情况下，实现圆形吻合器的无创伤导入和推进。
在一项I期前瞻性研究中，我们对60例连续接受左侧结直肠切除术的患者测试了新型圆形吻合器导入器装置的可行性和安全性。
吻合口距肛缘的中位距离为12 cm（7 - 20，n = 60）。总发病率为15%。未观察到死亡病例。参与研究的所有外科医生均认为圆形吻合器导入器的操作不存在问题。未遇到圆形吻合器导入器对所使用的圆形吻合器械产生干扰的情况。借助圆形吻合器导入器，吻合器总能顺利推进至结直肠残端末端。
圆形吻合器导入器的使用有助于结直肠吻合的双吻合技术。圆形吻合器导入器具有很大潜力，应在更大规模的研究中进行测试。
