Overview of Sleeve Gastrectomy and Roux-en-Y Bypass for Gastroparesis

Gastroparesis is a rare disorder characterized by delayed gastric emptying in the absence of mechanical obstruction. Initial management of gastroparesis consists of dietary modification, prokinetic agents, antiemetics, and optimizing underlying medical conditions (eg, glycemic control in diabetic patients). In a subset of patients, surgical intervention may be necessary such as with gastric pacemaker, pyloroplasty/pyloromotomy, or G-POEM. A further subset of patients may require sleeve gastrectomy or conversion to Roux-en-Y gastric bypass. Here, we focus on the indications and outcomes of sleeve gastrectomy and Roux-en-Y bypass for treatment of refractory gastroparesis.
