Per oral endoscopic pyloromyotomy (POP) has emerged as an endoscopic intervention for refractory gastroparesis. Early experience in the United States showed exciting clinical response rate, reduced gastroparesis symptoms, improved quality of life, and decreased gastric-emptying time during midterm follow-up up to 18 months. One recent study also showed that the number of patient emergency room visits and hospitalizations decreased significantly after POP. The procedure is technically feasible and safe. As more data become available, it is important to identify patients who would benefit most from this novel procedure.
