[Zenker's diverticulum treated by transoral diverticulostomy: technique and results].
OBJECTIVE
The surgical technique of transoral diverticulostomy by a modified Endo-GIAtrade mark Stapler (Multifire Endo GIA, Tyco Healthcare) is described. Experiences of this procedure in 31 patients are analysed and compared with different endoscopic and conventional surgical therapies of Zenker's diverticula, which are reported in the literature.


METHODS
From January 1996 to December 2005, 31 transoral diverticulostomies were performed. All patients were included porspectively into the study. The median follow-up time after diverticulostomy was 54 months. Manometry, pH-study of the esophagus, endoscopy and swallow radiography were performed before and after surgery. All patients completed the Gastrointestinal quality of live index (GQLI) and the Grosshadern dysphagia score (GHDS).


RESULTS
Subjective comfort of the patients as measured by the Smiley Index, the GQLI and the GHDS was increased significantly (p < 0.001) after therapy. Manometry showed that the upper esophageal sphincter functioned normally before and after intervention. A gastrografin swallow excluded leakage at the stapler suture-line in all cases. A conversion to a conventional cricomyotomy with resection of the diverticulum had to be performed once due to a dissection of the esophagus that occurred during insertion of the spreader. In one patient a bleeding out of the suture line was successfully treated with a metal clip. A prothesis broke due to the insertion of the spreader. Two patients developed relapses during the follow-up period of 54 months.


CONCLUSIONS
Compared to standard procedure the endoscopic minimal-invasive therapy proved to be safer. The operation time and the postoperative stay are shorter.
