[Endoscopic diverticulostomy for Zenker's diverticulum. Experience on 123 cases].
OBJECTIVE
To evaluate the short-term clinical outcome of the patients with Zenker 's diverticulum undergone to endoscopic esophago-diverticulostomy according to Collard.


METHODS
A retrospective analysis evaluated 123 patients. The most common symptom was dysphagia, severe in 50 patients (40.6%) and moderate in 73 (59.4%), with a mean dysphagia score of 2.3 (range 0-4). Regurgitation was present in 70 cases (56.9%), with a mean score of 0.8 (range 0-2). The mean diameter of diverticula was 4.1 cm (range 2.5-10). The procedure was undertaken in 87 male and 36 female with a mean follow-up of 69.1 months (range 1-168).


RESULTS
Good results were obtained in 82 patients (66.7%), and the improvement of symptoms in 24 (19.5%), data confirmed by pre versus postoperative dysphagia mean score (2.3 vs 0.4) and by regurgitation score (0.8 vs 0.2). The failures have been seen in 17 patients (13.8%). The mean time of the intervention was 18 minutes (range 15-40), while the mean length of postoperative hospital stay was 2.5 days (range 1-5), with a oral intake in first postoperative day (mean). Major complications were documented in 2 patients (1.6%), minor ones in 10 patients (6.1%), without mortality.


CONCLUSIONS
Nowadays esophago-diverticulostomy according to Collard, based on our results and on the literature data, represent the most effective and safe technique for the patients with Zenker's diverticulum, with low rate of morbidity and mortality compared to the others surgical on endoscopic procedures.
