Gastroenterostomy According to Petersen

Gastroenterotomy (Gastroenterostomy, Gastrostomelliotomy, Peritoneogastrostomy) involves creating a straight or conical opening in the anterior wall of the stomach, bringing it to the abdominal wall and suturing it to the skin. There are many different methods for creating a gastroenterostomy, usually having one common pattern. The main differences are in the methods of fixing the anastomosis to the abdominal wall. It is rational to create a large gastrostomy with a complex configuration, which subsequently minimizes the risk of relapse.

This method of inserting a probe into the stomach in some cases is the only possible way, because the initially existing defects of the abdominal wall do not allow the installation of a nasogastric tube and the creation of a full-fledged gastrostop. The operation is indicated only if the patient has no and unrepairable tracheoesophageal fistula. In case of obesity, correction of body weight after surgery is necessary, since obesity reduces the drainage function of the stomach and accelerates relapse. Normal functioning of the gastroenterostomy should be restored 6-8 weeks after the intervention.

It also has its advantages and disadvantages. The main disadvantage of this procedure is the high risk of complications such as infection, bleeding, gastric perforation or scarring. However, by reducing nausea and vomiting after gastric removal, this method may improve the quality of life of patients with gastric cancer. In addition, this method is suitable for people who cannot tolerate pain with other feeding methods.
