Abstract
Background
Minimally invasive surgery is used increasingly for colonic resection. With this procedure, the involved colon is dissected laparoscopically and exteriorized through a small incision, and the segment containing the tumor is resected. The anastomosis is performed extraperitoneally either by hand suture or with a stapler. This study was designed to evaluate the feasibility of using a memory-shape compression anastomosis clip (CAC) to perform laparoscopically assisted colonic anastomosis. The study was prompted by the authors’ successful experience with the CAC in an animal model and in 10 patients with diverse colonic cancers.
Methods
The sample consisted of 10 patients who underwent laparoscopic colonic surgery at the authors’ center. The anastomosis was performed with the CAC for five patients and with a stapler for five patients. To perform anastomosis with the CAC, the two edges of the resected colon are aligned. Two 5-mm incisions are made near the edges, through which the CAC, after cooling in ice water, is introduced in an open position using a special applier. In response to body temperature, the clip resumes its original (closed) position, thereby clamping the two bowel loops together. At the same time, the small scalpel incorporated in the applier makes a small incision through the clamped walls for the passage of gas and feces, and the clip is released into the intestine. The two 5-mm incisions are sutured. The clip is expelled with the stool within 5 to 7 days, creating a perfect uniform anastomosis.
Results
Neither group had complications, except one patient from the control group who experienced a small bowel obstruction attributable to a wound suture problem, which required laparotomy. His recovery was uneventful.
Conclusions
The use of the CAC for colonic laparoscopic surgery is simple and very efficient, shortening operation time. It creates a uniform anastomosis, approximating the no-touch concept in surgery, and may prevent infection. It also is lower in cost than the stapler.
