One of the most important problems of obesity surgery, which is performed very commonly in the world, is the long-term weight gain of the patients or the development of complications that disrupt the living standards due to the first surgical intervention. (vomiting, leakage, malnutrition, vitamin deficiency, hair loss, diarrhea) In this case, secondary intervention (revision surgery) is decided after the investigations. Detailed preparation is essential for the type of secondary intervention.
In the most frequently applied sleeve gastrectomy intervention, the rate of weight gain reaches around 20%. In this intervention; sleeve gastrectomy operation, gastric bypass, duodenal switch, sadı-s can be performed as secondary intervention. If patient gains weight again after gastric bypass operation, gastric bypass revision, sleeve gastrectomy, duodenal switch or sadı-s can be performed. In the rarely applied biliopancreatic diversion operations; bpd operation can be converted into gastric bypass operation due to malnutrition and chronic diarrhea. In the revision surgery, the first step is to find the real patient group who has indication, the second step is to choose the correct secondary intervention by making the preparation, the third step is to start the operation with experienced surgical team who can perform these operations successfully which have much more higher complication rate compared to the first intervention.
