In this open classroom, David Nocca et al. show a new procedure to handle morbid obesity. The sleeve gastrectomy (SG) is currently one of the most frequently performed bariatric procedures worldwide but there is a growing concern about its connection to gastroesophageal reflux. In general, it is estimated that 10% to 20% of patients suffer from symptomatic reflux after an SG, regardless of whether or not they used to have it before surgery (1) . In this study, 25 patients undergo a Nissen Sleeve gastrectomy. This surgical technique consists on creating a short and narrow Nissen valve around the sleeved stomach. Good results have been shown after a year of follow up. According to this group, the Nissen sleeve could be a great choice among bariatric techniques. even to prevent the new onset of GERD in sleeve patients.
