Endoscopic treatment of Zenker diverticulum: Results of a 7-year experience

Zenker's diverticulitis secondary to alendronate ingestion: a rare cause of recurrent dysphagia

“…The division of the common septum between the diverticulum and esophagus allows food and liquids to flow out of the diverticulum distally into the esophagus rather than lodge within the divertic- ulum. 2,9 In the study by Case and Baron, 9 all 22 patients had initial symptom improvement, and 18 (82%) maintained improvement at a mean follow-up of 12.7 months. Esophageal perforation was the most common procedural complication.…”

“…2,9 Endoscopic transoral stapling using a rigid endoscope has been recently attempted. 10,11 Recent studies have evaluated flexible endoscopic cricopharyngeal myotomy using the needle-knife papillotome.…”

“…Common symptoms include dysphagia, weight loss, regurgitation, halitosis, and chronic cough with recurrent pneumonia. 2 Bleeding from ZD has also been reported. [3][4][5][6][7] …”

“…Other studies have suggested an association with lower esophageal sphincter dysfunction and gastroesophageal reflux with subsequent hypertonic upper esophageal sphincter muscles leading to a pulsion diverticulum. 1,2 The prevalence of ZD in the general population is between 0.01% and 0.11%, and it usually manifests between the seventh and eighth decades of life. Common symptoms include dysphagia, weight loss, regurgitation, halitosis, and chronic cough with recurrent pneumonia.…”
