The nickel-titanium compression anastomosis ring device (ColonRing, NiTi Surgical Solutions, Netanya, Israel) has been cleared by the Food and Drug Administration in 2006 to construct gastrointestinal anastomoses. We evaluated the anastomotic leak rate after end-to-end anastomosis using the ColonRing device.
Using a multinational (16 countries), multicenter (178 centers) data registry provided by NiTi Surgical Solutions, Netanya, Israel, we retrospectively examined clinical data of patients who underwent elective laparoscopic or open left-sided colectomy and anterior resection from January 2008 to June 2010.
A total of 1,180 patients underwent end-to-end anastomosis using the ColonRing device during the study period. The overall anastomotic leak rate was 3.22% (38 patients). The median length of hospital stay was 6 days (range 2 to 21 days). The median ring expulsion time was 8 days. The earliest ring expulsion time was 6 days; however, in 1 patient, the ring did not expel. In 4 patients, the anastomosis had to be immediately recreated because of 1 misfiring and 3 incomplete anastomoses.
The use of the ColonRing device is feasible and safe and could be considered an alternative technology for end-to-end colorectal anastomosis.
镍钛合金压缩吻合环装置（ColonRing，NiTi Surgical Solutions，内坦亚，以色列）于 2006 年获得美国食品和药物管理局批准，用于构建胃肠道吻合。我们评估了使用 ColonRing 装置进行端端吻合后的吻合口漏率。
利用以色列 NiTi Surgical Solutions 提供的一项多中心（16 个国家，178 个中心）数据注册，我们回顾性检查了 2008 年 1 月至 2010 年 6 月期间接受择期腹腔镜或开腹左半结肠切除术和前切除术的患者的临床数据。
在研究期间，共有 1180 例患者接受了 ColonRing 装置的端端吻合。总的吻合口漏率为 3.22%（38 例）。中位住院时间为 6 天（范围 2 至 21 天）。中位吻合环排出时间为 8 天。最早的吻合环排出时间为 6 天；然而，在 1 例患者中，吻合环未排出。在 4 例患者中，由于 1 次故障和 3 次不完全吻合，需要立即重新进行吻合。
使用 ColonRing 装置是可行和安全的，可以被认为是端端结直肠吻合的替代技术。
