Long-term results show triple stapling facilitates safe low colorectal and coloanal anastomosis and is associated with low rates of local recurrence after anterior resection for rectal cancer.

摘要

BACKGROUND: During low anterior resection (AR), placement of a staple line distal to an occlusion clamp is often difficult due to the confines of a narrow bony pelvis. This study reviewed the results of AR with a technique in which a linear staple line is fired below the tumour as an oncologically safe occlusion clamp. METHODS: Between 1995 and 2000, a total of 174 patients were operated for rectal cancer, and 153 of these patients had AR. Triple stapling (TS) was used to place a line of staples that occluded the fully mobilised rectum below a tumour. After rectal washout, a further linear stapler was applied below the first, and the rectum was divided prior to a standard circular stapled anastomosis. RESULTS: TS was performed in 127 (83%) of 153 patients undergoing AR, and 9 TS patients developed leaks (7%). In the whole series of 174 cases, 9 patients had local recurrence (5%), but the local recurrence rate for procedures classified as 'locally curative' was 2%. CONCLUSIONS: Triple stapling reliably occludes the rectum allowing for distal rectal washout. It eliminates clamp slippage and faecal spillage and improves access to the distal rectum for low anastomoses.
