Low anterior resection of the rectum using a double stapling technique.
Using a double stapling technique in 30 patients, anterior resection of the rectum was attempted for low rectal carcinoma (n = 28), giant rectal adenoma (n = 1) and radiation-induced rectal stricture (n = 1). There were three emergency operations. The rectum was stapled transversely more than 3 cm below the tumour using the adjustable-angle linear stapler (Roticulator). Colorectal or coloanal anastomoses were constructed using the EEA circular stapler introduced per anum through the anorectal stump staple line. Ten coloanal and 19 low rectal anastomoses were achieved. A protecting transverse loop colostomy was fashioned in one patient with coloanal anastomosis who developed a vaginal tear during the procedure. In one patient technical failure necessitated conversion to abdominoperineal excision of the rectum. All staple rings and resection margins were intact and free from tumour. There were two clinical anastomotic leaks, both treated successfully with a defunctioning transverse loop colostomy. One patient developed a small infective pelvic haematoma 2 weeks after surgery which required drainage. Hospital stay ranged from 6 to 15 days (mean 8 days). Continence was normal in all patients at 8 weeks. One soft coloanal anastomotic stricture required dilatation. No recurrences have been detected during a follow-up of between 10 and 22 months.
