Abstract:

BACKGROUND: The nickel-titanium memory alloy has been extensively used in blood vessel prosthesis, internal fixation, and orthopedic stents, and its biological characters have obtained better understanding. In the meanwhile, the compression anastomosis technology has been mature.
OBJECTIVE: To evaluate the safety and efficacy of nickel-titanium memory alloy compression anastomosis clip (CAC) in gastrointestinal anastomosis.
METHODS: Totally 64 patients undergoing distal subtotal gastrectomy from June 2013 to February 2016 in Sichuan Provincial People’s Hospital were divided into two groups. Patients in CAC and control groups underwent gastrointestinal anastomosis using the CAC and disposable tantalum nail stapler, respectively.
RESULTS AND CONCLUSION: There were no significant differences in the operation time, stomach jejunum anastomosis time, postoperative exhaust time, eating time and hospitalization time between groups (P > 0.05). No complications such as anastomotic bleeding, anastomotic leakage and delayed gastric emptying occurred in the two groups. There was no anastomotic stenosis in the CAC group, but one case in the control group with the incidence of 3%. The abdominal X-ray examination of CAC group at postoperative 3 days showed that the CAC did not move, and was excreted at postoperative 9-28 days. Six months after operation, the gastrointestinal anastomosis was smooth without congestion and edema under endoscopy. In conclusion, the CAC for gastrointestinal anastomosis is safe and reliable, achieving the same or even better results with a disposable tantalum nail stapler, and will not cause anastomotic complications due to good histocompatibility.
