Zenker-divertikel: Endoskopisch-mikroskopische staplerassistierte Schwellenspaltung

Background. The endoscopic-microscopic staple-assisted esophagodivertikulostomy of Zenker's diverticulum is a new modification of endoscopic operation techniques which minimizes complications and is able to speed up the patient's convalescence. Patients and methods. A total of 22 out of 32 patients with Zenker's diverticulum underwent surgery. The operation involves cutting the wall between the diverticular sac and the oesophagus and, at the same time, closing the mucosal wound edges using the closed surgery method. Results. All operations were effective and uncomplicated. A total of 28 operations were performed on 22 patients. The operations due to relapse were predominantly necessary among younger patients, of whom three were operated endoscopically and three through the cricopharyngeal myotomy. Conclusions. The closed endoscopic-microscopic staple-assisted esophagodivertikulostomy of Zenker's diverticulum avoids opening the retropharyngeal and retrooesophageal areas and allows a quick convalescence in the mostly elderly patients. This technique is effective, safe and has no major complications.
