BACKGROUND

The most important thing in a bariatric procedure is its duration, which reflects the invasiveness and directly affects the patient’s safety profile.

OBJECTIVE

Purpose of work: to analyze the duration of bariatric surgeries and to evaluate the factors influencing this parameter.

MATERIAL AND METHODS

752 patients underwent various types of bariatric interventions from 2013 to 2020. The factors influencing the duration of the procedure were assessed.

RESULTS

The average duration was 110.2±14.2 minutes (med. 100 minutes). Differences in duration took place between endoscopic, laparoscopic and laparotomic operations, as well as between operations with two anastomoses (gastric bypass, biliopancreatic diversion) and with one anastomosis (mini-gastric bypass) or without anastomoses (sleeve gastrectomy, gastric band), medians 155, 240, 100, 95 and 90 minutes, respectively (p<0.001). The duration of the operation is significantly higher in superobesity and in older patients. The long-lasting influence of the accumulation of surgical experience on the duration of operations has been proven. Almost all simultaneous interventions, except for cruroraphy, significantly increased the duration of the operation. The risk of complications significantly increases if a surgery lasted more than 2 hours and 10 minutes. The use of special techniques and devices can reduce the operation time by 16.2 minutes.

CONCLUSION

It is advisable to give preference to single-anastomotic interventions (MGB-OAGB) in the presence of indications for more complex types of bariatric procedures, which with the same effectiveness can reduce the operation time by 1.5 times which has a positive effect on the safety profile in general.
