Gastrointestinal anastomosis has been a 100-year history in which a number of different materials have been used for gastrointestinal anastomosis, including silk threads, catgut threads, stainless steel sutures, novel single fiber threads and absorbable threads. During the last 30 years, anastomotic devices have been touted by surgeons. How to choose the anastomosis and the appliance anastomosis is still a matter of a plurality of academic debates.
Surgical complications gradually decrease as anastomosis techniques develop, but anastomotic fistulae remain one of the most feared postoperative complications. The incidence of anastomotic fistulae (1% -24%) was very different, while the incidence of lower rectal anastomotic fistulae (12% -19%) was higher than that of colonic anastomotic fistulae (11%). Anastomotic fistulae have a correlation with higher local recurrence rates and lower long-term survival rates. In addition, long-term gastrointestinal function can also be adversely affected by complications such as anastomotic modes, methods, and anastomotic fistulae. Over a hundred years, intestinal anastomosis techniques have been explored constantly, and the aim is to establish anastomosis techniques which are safer, more reliable and more convenient than manual suturing and have less impact on intestinal function, and new methods and new instruments have been reported frequently, and various anastomosis techniques have been proved to be comparable to standard manual anastomosis and anastomat techniques.
