Anastomosis is a dangerous, acute complication and is common in some digestive surgery, possibly bowel surgery. The gastrointestinal junction should be found out the cause and treated as soon as possible to avoid causing serious conditions, including the risk of death.

Anastomosis fistula is one of the possible complications after a surgery to join two hollow organs in the gastrointestinal tract. This is also one of the scary complications in gastrointestinal surgery, a consequence of anastomosis leading to leakage of fluid from the gastrointestinal tract, prolonging the postoperative care period.
