166. ROBOTIC-ASSISTED BILATERAL EPIPHRENIC DIVERTICULECTOMY WITH HELLER MYOTOMY AND DOR FUNDOPLICATION: A SURGICAL TECHNIQUE

Abstract Background Epiphrenic diverticula are rare esophageal diseases often associated with motility disorders such as achalasia. We present a case of bilateral epiphrenic diverticula in a patient with achalasia type III who presented with dysphagia. This video demonstrates the surgical technique of robotic-assisted bilateral epiphrenic diverticulectomy with Heller myotomy and Dor fundoplication, highlighting the six essential surgical steps. Methods A 72-year-old female presented with dysphagia for 3 years. An esophagogastroduodenoscopy revealed two epiphrenic diverticula without food content retention. A barium swallow revealed two epiphrenic diverticula, measuring 3.3 cm and 1.2 cm in diameter, on right and left side walls of distal esophagus, respectively. Esophageal manometry showed the lower esophageal sphincter (LES) pressure was 25.6 mmHg (normal
