Exploring the Effect of Colonic J-pouch in Anorectal Preservation Surgery for Ultra-low Rectal Cancer.

The occurrence of colorectal cancer has increased from the third most common cancer in 2018 to the second most common cancer in 2023. The practice of anal preservation surgery for ultra-low rectal cancer is being adopted gradually. Ultra-low rectal cancer patients who have undergone anal preservation are at an increased risk of developing significant bowel complications. The objective of this study was to examine the relationship between the type of bowel reconstruction following anal preservation surgery, and the subsequent outcomes of bowel function, quality of life and complication rates in patients with ultra-low rectal cancer.
