Study start date: January 1, 2021

Actual date on which the first participant was enrolled.

This study focuses on individuals in Poland who have previously undergone metabolic and bariatric surgeries. It aims to gather comprehensive preoperative history, including details about the patients' maximum weight, Body Mass Index (BMI), and the status of any related health conditions. The study also collects information about the initial surgery, such as the type of procedure, its duration, and technical aspects. The importance of this study lies in understanding the outcomes of these initial surgeries, including weight loss, improvement or remission of related health conditions, and reduction in medication use. It also considers any long-term complications that may have arisen from the initial surgery, such as new instances of reflux or issues with the gastric pouch. The study further investigates the reasons for revision surgeries, analyzing the time, type, and length of these secondary procedures. It delves into the technical details of these revision surgeries and gathers information about any complications and outcomes from hospital records and clinical follow-ups. The primary outcomes of this observational study include understanding the course of treatment for patients undergoing revision and secondary revision surgeries, identifying the most common reasons for these revision surgeries, and determining the types of surgeries most frequently chosen for revision procedures.
