MARCHESINI, Simone Dallegrave; BARETTA, Giorgio Alfredo Pedroso; CAMBI, Maria Paula Carlini  and  MARCHESINI, João Batista. Endoscopic plasma argon coagulation in treatment of weight regain after bariatric surgery: what does the patient think about this?. ABCD, arq. bras. cir. dig. [online]. 2014, vol.27, suppl.1, pp.47-50. ISSN 0102-6720.


Bariatric surgery, especially Roux-en-Y gastric bypass is an effective treatment for refractory morbid obesity, causing the loss of 75% of initial excess weight. After the surgery, however, weight regain can occur in 10-20% of cases. To help, endoscopic argon plasma coagulation (APC) is used to reduce the anastomotic diameter. Many patients who undergo this treatment, are not always familiar with this procedure and its respective precautions.


The aim of this study was to determine how well the candidate for APC understands the procedure and absorbs the information provided by the multidisciplinary team.


We prepared a questionnaire with 12 true/false questions to evaluate the knowledge of the patients about the procedure they were to undergo. The questionnaire was administered by the surgeon during consultation in the preoperative period. The patients were invited to fill out the questionnaire.


We found out that the majority learned about the procedure through the internet. They knew it was an outpatient treatment, where the anesthesia was similar to that for endoscopy, and that they would have to follow a liquid diet. But none of them knew that the purpose of this diet was to improve local wound healing.


Bariatric patients who have a second chance to resume weight loss, need continuous guidance. The internet should be used by the multidisciplinary team to promote awareness that APC will not be sufficient for weight loss and weight-loss maintenance in the long term. Furthermore, there is a need to clarify again the harm of drinking alcohol in the process of weight loss, making its curse widely known.
