Obesity has been proven to be a significant independent risk factor for hiatal hernia. In morbidly obese patients, the usual techniques to improve gastroesophageal reflux after hiatal hernia repair could have poorer outcomes than in the general population. Laparoscopic Roux-en-Y gastric bypass (LRYGBP) has been demonstrated to be an effective procedure in controlling symptoms and complications of gastroesophageal reflux in these patients. Therefore, LRYGBP is one of the most frequent procedures performed in bariatric surgery. The authors report a case of a 41-year-old man with a body mass index (BMI) of 44.6 kg/m2 who was diagnosed with giant type III hiatal hernia. A laparoscopic approach for both hiatal hernia repair and LRYGBP was performed. At 6 months follow-up, the patient has lost 30% of excess body weight (BMI 34.4), and there is no evidence of recurrence of the esophageal hernia.
