[Low colorectal anastomosis: a comparison of manual and mechanical sutures]

Sixty-three carcinomas of the lower third of the rectum operated of anterior resection with low colorectal or coloanal anastomosis are presented. Handsewn anastomoses were performed in 33 patients, while staplers were used in 30 cases. The average distance of the tumor from the anal verge is 10.8 cm. in hand sutured anastomoses and 7.8 cm. in stapled ones. Dehiscences, stenosis and temporary incontinence are observed more frequently after stapled anastomosis, while the incidence of neoplastic recurrences is higher in sutured anastomosis; hospital stay and mortality are similar in the two series. Our results and literature review show that both techniques are comparable though maintaining their own specific identity and precise indication.
