ABSTRACT
Constructing successful anastomosis is an important concept in gastrointestinal tract surgeries, which can be affected by various factors such as preoperative bowel condition, intra- and postoperative complications, bleeding and the device characteristics. Suturing, stapling and compression anastomosis are different techniques. Despite the invention of compression anastomosis, which goes back almost two centuries, this method has not obtained the popularity of the suturing and stapling anastomosis and further studies are required. Designing methods and devices with no drawbacks might reduce the complications associated with anastomosis as the alternative to suturing and stapling anastomoses. Several materials can be used as reinforcement materials, which can improve the consequences of the stapled anastomosis. In addition to reinforcement materials, other forms of supports have been proposed, which might be capable of reducing the postoperative complications of anastomosis. In this study, we briefly review various types of anastomotic techniques and associated complications in different types of gastrointestinal surgeries
