Endoscopic sleeve gastroplasty safety profile - retrospective, single-center analysis of 222 consecutive patients including the learning curve period.

Abstract

The global obesity epidemic affects over 1.9 billion adults, with an additional 650 million classified as obese. Endoscopic sleeve gastroplasty (ESG) is a type of minimally invasive endobariatric procedure. It is a less invasive alternative to laparoscopic sleeve gastrectomy (LSG). Although the effectiveness of ESG is lower, it might have a better safety profile. To assess the safety profile of ESG and describe complications classified as grade II or higher, using the Clavien-Dindo classification, with an overview of the learning curve. We included 222 patients who underwent ESG at the Endoscopic and Bariatric Surgery Center of the hospital in Brzeziny from January 2021 to October 2023. The severity of complications was evaluated based on the Clavien-Dindo classification, considering complications of grade II or higher. Among the studied group of patients, a total of 4 (1.8%) cases of perioperative bleeding into the gastrointestinal tract were recorded. One (0.5%) patient had the most severe grade IVb complication that required treatment in the Intensive Care Unit. All patients with serious adverse events (SAE) fully recovered. We did not observe an association between the learning curve, procedure duration, and the frequency or severity of postoperative complications. The presented results confirm the high safety of ESG in the treatment of obesity.
