title: Supraperitoneal colorectal anastomosis: hand-sewn versus circular staples--a controlled clinical trial. French Associations for Surgical Research.
abstract: BACKGROUND
  Although used widely for supraperitoneal anastomoses, circular stapled anastomoses have never been proved better than hand-sewn anastomoses. In the one prospective controlled trial that studied these anastomoses specifically, the only significant difference found was that there were more clinically obvious leakages with the circular stapled variety, but not in the overall clinical and roentgenologic leakage rates.
  
  
  METHODS
  One hundred fifty-nine consecutive patients (88 men and 71 women, mean age 65.8 +/- 12.1 years) were randomized to undergo hand-sewn (n = 74) or circular stapled (n = 85) supraperitoneal colorectal anastomosis after left colectomy.
  
  
  RESULTS
  Patient demographics were similar in both groups. Overall mortality was 1.3% (2 of 159; one in each group). No statistically significant difference (NS) was found in the rate of early complications, including anastomotic leakage (4 of 74 versus 6 of 85) in the hand-sewn and stapled anastomoses, respectively). Mishaps (n = 10) and hemorrhage (n = 5) occurred in the stapled group only. Stapled anastomoses took an average of 8 minutes less to perform (p < 0.001), but this time gain did not significantly influence the overall duration of operation (identical median times). The median duration of hospitalization was 13 and 14 days, respectively (NS). At 8 months there were 2 of 74 strictures in the hand-sewn group and 4 of 85 strictures in the stapled group (NS).
  
  
  CONCLUSIONS
  According to these results, there seems to be no advantage of routine or regular use of stapling instruments for supraperitoneal colorectal anastomosis.
