[Mechanical compression anastomosis (AKA-2) of the colon and rectum. Results of a prospective clinical study].

Based on the highly superior mechanical and functional properties of an experimental sutureless anastomosis performed without any foreign material compared to conventional anastomosis we have introduced a sutureless compression anastomosis (AKA-2) to colorectal surgery and controlled the outcome prospectively. This type of anastomosis was employed in 30 patients with sigmoid and rectal resections for carcinomatous and inflammatory bowel disease. The first 3 patients and further 3 high-risk patients got a protective colostomy. The clinical outcome was uneventful in all patients but 2 with anastomotic fistula. Radiological controls showed no further fistula. The study revealed no negative side effects of the compression anastomosis but the procedure seems to provide considerable advantages by complete mechanical relief of the anastomosis and early epithelial covering of the anastomotic line.
