title: Double versus single stapling technique in rectal anastomosis.
abstract: A retrospective analysis to compare the single vs double stapled technique for rectal anastomosis was carried out on patients that underwent radical surgical resection between January 1986 and January 1989 at the Istituto Nazionale Tumori of Milan. In 143 patients anastomotic integrity had been checked both intraoperatively with air insufflation and postoperatively by water soluble contrast enema. A single stapled anastomosis (SST) was performed using the EEA instrument in 94 patients, and in 49 patients a double stapled (DST) using the EEA and TA instruments was performed. The level of the anastomosis was less than or equal to 10 cm from the anal margin in 94 patients (54 SST, 40 DST). In 52 patients it was greater than 10 cm (40 SST, 12 DST) (SST vs DST ns). The presence of anastomotic dehiscence occurred in 29 (20%) patients (17 SST, 12 DST). This was not related either to the anastomotic site or to the suture technique used. The dehiscence was located on the posterior wall in 79% of cases and in 58% the size was less than 1 cm. In 78% clinical symptoms were evident. There was no difference between SST and DST patients. Further surgery (colostomy) was necessary in six patients (2 SST, 4 DST). Two patients died through complications (1 SST, 1 DST); making an overall mortality rate of 1.0% and 2.0% in each group. There was no difference in infection rate and length of postoperative stay in the two groups. Our data demonstrate that both methods give similar results.(ABSTRACT TRUNCATED AT 250 WORDS)
