To evaluate outcomes following endoscopic management of Zenker's diverticula using a carbon dioxide laser (CO 2 ) or stapler‐assisted technique, a systematic review and meta‐analysis were conducted. Seven retrospective, uncontrolled case series including 391 procedures met selection criteria. No higher quality studies were identified. Outcomes favoring the stapler technique included a shorter duration of nil per os (NPO) status (2 studies), length of hospitalization (LOH, 2 studies), and fewer postoperative fevers and abnormal chest x‐rays (1 study). Outcomes favoring the CO 2 technique included greater improvement in postoperative dysphagia and regurgitation scores (2 studies) and a lower revision rate (1 study). Meta‐analysis demonstrated increased nondental complications in the CO 2 group (odds ratio 3.81; 95% confidence interval, 1.37‐10.59; P =. 01) but no difference in duration of NPO ( P =. 06), LOH ( P =. 07), overall complications ( P =. 08), dental complications ( P =. 57), major complications ( P =. 38), or revision surgery ( P =. 82). Implications are limited by the quality of studies identified.
