[The physiopathology and therapy of esophageal diverticula].

The authors report their experience in the management of 14 patients affected by esophageal diverticula and surgically treated (9 had cervical diverticula, 2 had epibronchial diverticula and 3 had epiphrenic diverticula). All these patients underwent a diverticulectomy: in 3 cases the diverticulectomy was associated with a subdiverticular myotomy. In the last three cases the resection of the diverticulum was performed using an automatic stapler. The follow-up of these patients was prolonged for a period of 5 years with clinical, radiographic and endoscopic evaluations performed at 6 monthly intervals. The most recently operated patient has a minimum follow-up of 22 months. There were no operative deaths and none of the patients complained of recurrence of the diverticulum or of the preoperative symptomatology. No significant complications were observed in the postoperative period in the patients who underwent a simple diverticulectomy or in the cases in which a subdiverticular myotomy was associated. The scant number of observed patients does not allow us to draw any conclusion about the necessity maintained by most authors of an associated myotomy. It is however evident that this adjunctive procedure doesn't cause any further difficulty and is not loaded with an increased risk of complications. Finally the authors believe in the usefulness of performing the diverticulectomy with an automatic stapler, these devices allow in fact a considerable reduction of the surgical time and prevent dangerous contaminations of the operative field.
