diverting stoma necessary for different coloanal anastomoses?

To evaluate the importance of diverting stomas in decreasing complications after coloanal anastomosis. Thirty patients with low rectal adenocarcinomas underwent low anterior resection and 15 of them underwent stoma construction. Follow-up was 3 years. There was 18 male and 12 female. Non-stoma patients tended to have more early complications and more probability of being free of stricture at 3 years. Straight anastomosis has greater rates of complications than anastomosis after coloplasty or colonic pouch. Defunctioning stoma has a protective role after low anterior resection after different coloanal anastomosis
