Reoperative bariatric surgery procedures are becoming a significant part of MBS practice. They are performed to deal with complications and weight gain after the primary procedure. One of the most common complications in patients with a history of gastric bypass is marginal ulcer (MU) and stricture. The incidence of marginal ulcer (MU) is 1-16%, although true incidence is unknown. Bleeding and perforation are the presenting factors in some patients. Chronic MU is often accompanied by abdominal pain and stricture as in the case presented.

Sleeve Gastrectomy has become the most common bariatric procedure worldwide due to its good results, simplicity, and low complication rate. However, a number of patients can experience weight regain after several years. Although most of the time bariatric surgeons would prefer revision to a duodenal switch or a bypass, new evidence has shown that a re-sleeve gastrectomy is a feasible option, specially when the patient had a good initial outcome in the absence of reflux and hiatal hernia and when there is a dilation of the gastric tube. We present the case of a 34-year-old female patient who underwent a Sleeve gastrectomy 6 years ago, losing 43 kilos, from 113 to 70 kilos over 18 months (BMI 41 to 25). She maintained her weight for 3 years, but after having her second daughter she progressively regained weight. She came to the hospital with a BMI of 35, a relapse of joint disease, and sleep apnea. Weight 97, Height 1.66m. Preoperative studies showed a dilated gastric tube but no evidence of hiatal hernia or reflux. After the assessment of the multidisciplinary team, the re-sleeve surgery has been selected as the reasonable option.
