摘要
Bariatric surgeries are often complicated by de-novo gastroesophageal reflux disease(GERD)or worsening of pre-existing GERD.The growing rates of obesity and bariatric surgeries worldwide are paralleled by an increase in the number of patients requiring post-surgical GERD evaluation.However,there is currently no standardized approach for the assessment of GERD in these patients.In this review,we delineate the relationship between GERD and the most common bariatric surgeries:sleeve gastrectomy(SG)and Roux-en-Y gastric bypass(RYGB),with a focus on pathophysiology,objective assessment,and underlying anatomical and motility disturbances.We suggest a stepwise algorithm to help diagnose GERD after SG and RYGB,determine the underlying cause,and guide the management and treatment.
