Microendoscopic laser diverticulotomy for hypopharyngeal diverticulum.

Progressive dysphagia due to a pharyngeal pouch eventually requires surgical treatment. Thirty-four patients treated by laser diverticulotomy in a 6-year period were reviewed for age, length of hospitalization, associated medical problems, postoperative course, and results. The operative technique is described in detail, and a new, slimmer diverticuloscope is introduced. Microendoscopic laser diverticulotomy offers excellent visualization by means of the operating microscope together with a double-lipped diverticuloscope and is a minimally invasive, relatively simple, controlled procedure with proven, predictable results and few complications. It can be recommended as the treatment of choice for patients of all ages, whether the pouch is large or small.
