The cause of these acquired diverticula is controversial, although most likely it is related to cricopharyngeus muscle dysfunction. Treatment is directed toward correcting the underlying sphincter dysfunction and managing the diverticulum. Endoscopic diverticulotomy requires division of the cricopharyngeus and the common wall between the esophagus and diverticulum, a technique popularized by Dohlman. We reviewed the results of 40 endoscopic diverticulotomy patients, ranging in age from 46 to 88 years, many of whom had significant existing comorbidities. The mean size of the diverticula was 4.1 cm, mean surgery time was 41 minutes, and mean hospital stay was 4.5 days. Thirty\u2010seven of 40 patients, including 3 whose previous external procedure was not successful, returned to a regular diet, reported no regurgitation and were satisfied with the procedure. Complications in order of occurrence were pneumomediastinum (4 patients), urinary tract infection (2), upper respiratory tract infection (2), and lip laceration (1). Our results compare favorably with those of external approaches. The technique should be considered safe, expedient, and effective, particularly in patients with existing comorbidities.<\/jats:p>","DOI":"10.1016\/s0194-59989770327-9","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T13:27:21Z","timestamp":1664371641000},"page":"209-212","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Endoscopic Zenker's Diverticulotomy (Dohlman Procedure): Forty Cases Reviewed"],"prefix":"10.1002","volume":"116","author":[{"given":"Peter G.","family":"Von Doersten","sequence":"first","affiliation":[{"name":"Department of Head and Neck Surgery Kaiser Permanente Medical Center Oakland California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frederick M.","family":"Byl","sequence":"additional","affiliation":[{"name":"Department of Head and Neck Surgery Kaiser Permanente Medical Center Oakland California"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,12,20]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"85","article-title":"A case of obstructed deglutition, from a preternatural dilatation of, and bag formed in, the pharynx; in a letter from Mr. Ludlow, surgeon, at Bristol, to Dr. William Hunter.
