[Manual and mechanic anastomosis. Comparison in oncologic surgery of the colon and rectum].

Personal experience in the treatment of 60 cases of cancer of the large bowel with left hemicolon and rectal localisation is reported. 20 manual double layer anastomoses (group I), 20 single layer (group II) and with mechanical stapler (EEA stapler) (group III) were carried out in consecutive series. The results are reported in terms of early local and general complications: specifically 13 cases of anastomotic dehiscence of which 69.2% were observed in group I, 15.4% in group II and 15.4% in group III. Total postoperative mortality was 5%, average hospitalisation was as follows: 19 days group I, 14 days group II, 17 days group III. The value of single layer anastomoses, which is comparable to results with the stapler whose use is essential in cases of real manual technical difficulty, is stressed.
