Giant mid-esophageal diverticulum treated with diverticular peroral endoscopic myotomy: a case report

Abstract Background Esophageal diverticulum is rare and usually requires surgical treatment. Diverticular peroral endoscopic myotomy(D-POEM) is considered to be a novel technique that can be effectively used for septotomy in patients with esophageal diverticulum. Case presentation: A 73-year-old male patient was admitted to our hospital, complaining of recurrent dysphagia for more than 8 years and aggravated dysphagia for 2 months. Esophagogram revealed a sac in the anterior esophageal region and gastroscopy showed a giant diverticulum in the mid-esophagus. He was treated with D-POEM and had good clinical outcome. The patient was discharged 6 days after operation and has been doing well, and no recurrence was observed. Conclusion D-POEM is an effective and minimally invasive method for esophageal diverticulum, but long-term efficacy remains to be proved by more studies.
