Abstract：
One-anastomosis gastric bypass (OAGB) complications include inadequate weight loss, recurrent weight gain (RWG), and gastroesophageal reflux disease (GERD). Conversion to distal Roux-en-Y gastric bypass (D-RYGB) may be an effective conversional approach. A 38-year-old female underwent OAGB with a body mass index (BMI) of 53 kg/m2 and 43% initial total weight loss but had RWG to BMI of 44 kg/m2 over 5 years with refractory GERD symptoms. She underwent D-RYGB conversion, creating a 330 cm biliopancreatic limb, 75 cm Roux limb, and 400 cm total alimentary limb length to decrease the chance of malnutrition. At 2 weeks, GERD symptoms were resolved completely. By 12 months, 42% total weight loss was achieved with normal nutritional parameters. For RWG and refractory GERD after OAGB, conversion to D-RYGB can promote weight loss and GERD symptom control while preventing nutritional deficiencies.
摘要：
一次吻合胃旁路术（OAGB）并发症包括体重减轻不足，经常性体重增加(RWG)，胃食管反流病（GERD）。转换为远端Roux-en-Y胃旁路术（D-RYGB）可能是一种有效的转换方法。一名38岁的女性接受了OAGB，体重指数（BMI）为53kg/m2，初始总体重减轻了43％，但在5年内RWG至BMI为44kg/m2，伴有难治性GERD症状。她接受了D-RYGB转换,创建一个330厘米的胆胰肢，75厘米Roux肢体，和400厘米的总消化道长度，以减少营养不良的机会。两周后，GERD症状完全缓解。到12个月,在正常营养参数下实现42%的总体重减轻。对于RWG和OAGB后的耐火GERD，转换为D-RYGB可以促进体重减轻和GERD症状控制，同时防止营养缺乏。
