[Stapled versus hand sewn anastomosis in elective and emergency colorectal surgery]

Abstract

We studied the incidence of anastomotic leakage in colorectal surgery with the alternative use of stapled anastomosis, hand sewn anastomosis and stapled/hand sewn anastomosis. 477 consecutive patients admitted for elective or emergency colon surgery were divided in: Group I? 337 elective patients submitted to mechanical bowel preparation; Group II - 140 emergency patients operated without mechanical bowel preparation. We analyzed surgical complications in the two group considering the different anastomosis made (stapled, hand sewn and stapled/hand sewn). Anastomotic leakages were 11 (3.3%) in Group I: 7 in stapled (3,4%), 2 in hand sewn (2,1%) and 2 in stapled/hand sewn anastomosis (5,3%); 10 patients (91%) with peritonitis or intra-abdominal abscess required re-intervention and there was a correlated death. In Group II there were 6 anastomotic leakages (4,2%): 1 in stapled (1,4%), 3 in hand sewn (8,3%) and 2 in stapled/hand sewn anastomosis (5,7%); four patients required re-intervention and there were no correlated deaths. Mean postoperative stays were similar among the different techniques of suture in the two groups. No statistically significant differences in surgical complications were noted among stapled, hand sewn and stapled/hand sewn anastomosis. The choice should be based on personal preference and surgeon experience, considering costs, using hand sewn suture whenever is possible.
