End to End Anastomosis With Omega Suture Versus End to Anterior Rectal Wall In Colorectal Anastomosis in Sigmoid and Upper Rectal Cancer

After the rectum was divided with a linear stapler, the circular stapler was placed allowing the anvil rod to penetrate the rectal stump near the linear stapler line. An omega suture including both ends of the linear stapler line was placed. The linear stapler line was approximated around the anvil rod of the circular stapler in an omega shape fashion as the omega suture was tied. This technique resulted in a complete resection of linear stapler line by the circular stapler.

"A burse string suture was applied over the anvil of the circular stapler at the transection point of the descending colon using prolene 2/0.~The circular stapler introduced though the anus and its rod directed toward the anterior rectal wall and colorectal anastomosis was performed."
