Early surgical outcomes of NiTi endoluminal compression anastomotic clip (NiTi CAC 30) use in patients with gastrointestinal malignancy.
BACKGROUND
The NiTi endoluminal Compression Anastomotic Clip (CAC™) 30 (NiTi CAC 30) (NiTi Alloys Technologies, Ltd., Netanya, Israel) is a new device with shape-memory characteristics. We aimed to investigate the safety and early surgical outcomes of NiTi CAC 30 for intestinal anastomosis in patients with gastrointestinal malignancy.


METHODS
Fifty patients operated on with NiTi CAC 30 were matched for sex, age, body mass index, operation type (open versus laparoscopy), operation name, and anastomosis type with patients in a control group operated on with a stapling device between November 2009 and May 2010. Early clinical outcomes were investigated.


RESULTS
One misfired case of NiTi CAC 30 was excluded. Between the two groups, no significant differences were observed in demographics except for previous abdominal operation history. The results of early clinical outcomes were investigated, including operation time, estimated blood loss, time to first flatus, first defecation, and discharge, and complications. No differences were noted. Postoperatively, migration started in 1 patient between 3 and 5 days, 11 patients between 6 to 7 days, and 37 patients after 8 days. The expulsion of 31 cases occurred between 2 and 3 weeks, postoperatively. The NiTi CAC 30 was expulsed within 1 week in 4 patients and between 1 to 2 weeks in 8 patients. An expulsion occurred in 1 case at over 4 weeks. No problems related to early migration and expulsion were observed, and no anastomotic leakage and bleeding occurred.


CONCLUSIONS
Intestinal anastomosis with the NiTi CAC 30 was safe and feasible without anastomotic leakage and reoperation compared with the stapling technique.
