[Stapled anastomoses in colorectal surgery].
The purpose of this paper was to analyze the advantages, indications and results of stapled circular anastomoses in colorectal surgery. In the last four years (1995-1998), fifteen patients underwent stapled anastomoses after Dixon's anterior rectal resection for cancers of upper and midrectum (11 patients), total colectomy with ileorectal anastomosis for malignant familial polyposis (1 patient), segmental colectomy of transverse and descending colon (1 patient with synchronous colic and rectal cancers, having concomitant rectal resection for cancer), previous Hartmann's resection for perforated upper rectal cancer (1 patient) or distal sigmoid diverticulitis (1 patient). The anastomoses have been performed in end-to-end fashion (11 patients), according to the Knight's technique (2 cases) or in side-to-end fashion (2 patients). As most frequent associated technique with stapled anastomoses, anterior rectal resection for cancer was performed with 2 cm of clearance beyond the macroscopic margin of tumor. Distal margin of resection was histologically verified and it proved to be free of tumor cells. There was no operative mortality. Anastomotic leakage occurred in three patients because of imperfection of stapled anastomosis (2 cases) or after local irradiation (1 case). Spontaneous closure was seen in one patients. The other two patients needed reoperation for suture or colostomy. Late clinical, endoscopic and X-ray controls did not discover local recurrences. Functional results were good in terms of stool frequency and continence. In conclusion, stapled fashioned anastomoses have the main indication in sphincter saving Dixon's and Hartmann's procedures. In these cases, stapled anastomoses are easier than manual technique, reduce operative time and improve suture reliability.
