Esophageal diverticular disease is an uncommon entity for which appropriate treatment remains somewhat controversial. The acquired diverticulum is typically classified by its location (upper, middle, epiphrenic) and pathogenesis (traction, pulsion). Traction diverticula have been ascribed to inflammation and adhesions from periesophageal lymph nodes arising from, for example, pulmonary tuberculosis or histoplasmosis. Pulsion diverticula arise from a number of factors, most notably esophageal dysmotility, functional or mechanical distal esophageal obstruction, and focal weakness of the esophageal wall.
