title: Endoscopic laser-assisted diverticulotomy without versus with wound closure in the treatment of Zenker's diverticulum.
abstract: The aim of the present study was to compare the modifications of endoscopic laser-assisted diverticulotomy regarding closure of mucosal wound at the cricopharyngeal bridge. The results of 62 cases after endoscopic laser-assisted diverticulotomy without and with wound closure were retrospectively compared. After laser-assisted transection of the cricopharyngeal bridge, the mucosa wound was left open (OW) in 35 cases (56%), whereas a closure of the mucosa wound (CW) with sutures and fibrin glue was performed in 27 patients (44%). Duration of hospitalization, residual diverticular sac rate and occurrence of complications did not differ significantly between the two groups. Mean surgical time was significantly less in the OW cases. According to these results, it can be assumed that readapting and sealing the wound after transecting the cricopharyngeal bridge does not significantly reduce the complication rate. It does, however, extend the length of surgery and increases the cost of the procedure.
