Technique for instant stapling of the sigmoid mesentery and mesorectum in laparoscopic colorectal surgery.

BACKGROUND: Dissection of the mesentery of the distal sigmoid or rectum before transection with a linear stapler in laparoscopic colorectal surgery is time consuming, can cause irritating bleeding, and can harm the vascularization of the distal part of the bowel anastomosis. METHODS: A new linear stapling technique in laparoscopic colorectal surgery is presented. This technique is used to perform transection of the distal sigmoid or proximal rectum with a linear stapler by instant stapling of both the mesentery/mesorectal fat and the intestine instead of standard preliminary dissection. This technique was performed in a pilot study of 27 laparoscopic colorectal operations for benign or malignant disease. RESULTS: In none of the 27 patients was leakage of the anastomosis observed. CONCLUSIONS: This new technique is safe and effective. It saves time, avoids troublesome dissection of the mesentery/mesorectum, which can cause bleeding or damage to the bowel, and preserves vascularization of the distal part of the anastomosis.
