[Surgical treatment of diverticula of the thoracic esophagus].

Pathogeny of thoracic esophageal diverticuli, divided into parabronchial and epiphrenic, appears to have been modified by development of functional esophageal motility measurement. We present 23 patients with epiphrenic diverticuli and 3 with parabronchial diverticuli (15 male and 11 female with a mean age of 61 years). Twenty-four underwent surgery: 4 isolated diverticulectomy, 7 diverticulectomy and associated myotomy, 5 myotomy alone, 3 antireflux procedure alone. Three patients required esophagectomy for carcinoma in a diverticulum, for a huge diverticulum adherent to the inferior pulmonary vein. One patient presenting with perforation of a carcinomatous diverticulum in the pleura was treated with pleurotomy and has died. No fistula has been notified. Long term results had been analysed with a mean follow up of 4 years. Special attention has been reported on development of gastro-esophageal-reflux. The finding of a thoracic diverticulum requires evaluation by barium swallow, fibroscopy and functional test which should indicate the operation required. Long term analysis should include functional manometric evaluation and a pHanalysis as long term results are reduced by the appearance of gastro-esophageal-reflux.
