Based on the available publications, the article presents an analysis of studies on the problem of simultaneous execution of cholecystectomy, ventral and paraesophageal hernia repair during bariatric intervention. If there is a clinical picture of chronic calculous cholecystitis, simultaneous cholecystectomy is justified and does not lead to a significant increase in the number of complications. In case of asymptomatic stone-bearing disease, the optimal tactic remains controversial, both surgical treatment and observation are possible. In the absence of gallstone disease, all patients after surgical correction of excess weight are shown to take ursodeoxycholic acid, while performing preventive cholecystectomy is not recommended. Simultaneous ventral hernia repair is justified only for small defects ( 10 cm) of the anterior abdominal wall. If a paraesophageal hernia is detected in patients with morbid obesity, bariatric surgery may be combined with cruroraphy.
