Although staplers bring convenience to doctors and simplify the difficulty of colorectal surgery. However, there are still unresolved issues during surgery - serious complications - anastomotic leakage, leakage of fecal contents in the abdominal cavity, which may lead to sepsis or even death. Leakage is usually managed by placing a shunt stoma to protect the surgical anastomosis during the healing process, and is closed surgically 3 to 6 months after the initial surgery. Although diversion stoma can reduce anastomotic leakage, it can lead to a very poor quality of life for patients in the months after surgery.
