RESUMO
Bariatric surgery is now recognized as the most effective treatment of morbid obesity, leading to durable weight loss and resolution of associated co-morbidities. Roux-en-Y gastric bypass and sleeve gastrectomy are the two most widely used operations today. However, potentially serious medical, surgical, and/or psychiatric complications can occur that raise questions regarding the benefits of this type of surgery. These complications can lead to surgical re-operations, iterative hospitalizations, severe nutritional deficiencies and psychological disorders. Indeed, death from suicide is said to be three times higher than in non-operated obese patients. These results are of concern, all the more because of the high prevalence of patients lost to follow-up (for various and multifactorial reasons) after bariatric surgery. However, better knowledge of post-surgical sequelae could improve the information provided to patients, the preoperative evaluation of the benefit/risk ratio, and, for patients undergoing surgery, the completeness and quality of follow-up as well as the detection and management of complications. The development of new strategies for postoperative follow-up such as telemedicine but also the mobilization of all the actors along the healthcare pathway can make inroads and warrant further study.

Bariatric revisional surgery represents an important new issue for obese patients because of the considerable rate of failure and complications following bariatric surgery. As the frequency of bariatric procedures increases, so too does the incidence of revisional surgery, which has become becoming increasingly important. The surgeon must know the indications and the results of the various revisional procedures in order to best guide the therapeutic decision. The current challenge is to correctly select the patients for revisional surgery and to choose the appropriate procedure in each case. Multidisciplinary management is essential to patient re-assessment and to prepare the patient for a re- intervention. The objective of this update, based on data from all the most recent studies concerning revisional surgery, is to guide the surgeon in the choice of the revisional procedure, depending on patient characteristics, co-morbidities, the previously performed procedure, the type of failure or complication observed, but also on the surgeon's own habits and the center's expertise. The collected results show that revisional surgery is difficult, with higher complication rates and weight-loss results that are often lower than those of first-intent surgery. For these reasons, patient selection must be rigorous and multidisciplinary and the management in expert centers of these difficult situations must be encouraged.
