Comparison of Sutured Intestinal Anastomosis and Stapler Intestinal Anastomosis in Dogs

This study was carried out to investigate the difference between sutured anastomosis and stapler anastomosis (open lumina technique) of jejunum in dogs. Fifteen mongrel-breed female dogs weighting 4 to 6 kgs were allocated to three groups; sutured end-to-end anastomosis (Group I), sutured side-to-side anastomosis (Group II) and stapler anastomosis (Group III), five dogs per each group. All dogs in different anastomosis pattern were compared with time for total operation and suture elapsed for intestines to anastomose, clinical signs, status of feces, complications for 14 days after operation. The total operation time and suture time needed for intestinal anastomosis were significantly(p<0.05) shorter in Group III than Group I and II. All dogs showed no significant difference in vitality, appetite, vomiting between groups for 14 days after operation. All dogs, except one dog in Group II, showed normal vitality and appetite since 7-8 days after operation. Initial return of fecal passage showed in all dogs 8 days after operation and thereafter normal feces were observed in most of the dogs. According to results, all dogs with normal vitality and appetite for 8 days showed good prognosis. In complications after operation, only one dog in Group II showed dehiscence of anastomotic site. There was significant(p<0.05) differences between groups in speed of operation. And all dogs, except one dog in Group II, showed good clinical condition and prognosis. In conclusion, the stapler anastomosis is considered to be more reliable, faster, and precision method compared to the sutured anastomosis for intestinal anastomosis in dogs.
