Objectives Ingestion of foreign bodies ( FB s) in the upper esophagus is common in S outh C hina. It is difficult to manage because of limited working space and inadequate visual field in this area. This randomized, controlled study aimed to evaluate the usefulness of a transparent cap in the endoscopic management of FB s in the upper esophagus. Methods Adult patients suspected of FB s in the upper esophagus based on the history of FB s ingestion, symptoms, and barium contrast examination were screened for the study between M arch 1, 2009 and D ecember 31, 2010. Seventy patients with endoscopic‐confirmed FB s in the upper esophagus were recruited and were randomly assigned to two groups: transparent cap‐assisted esophagogastroduodenoscopy group ( n = 35) or conventional esophagogastroduodenoscopy group ( n = 35). The type, size, and location of FB s, the operation time for removing the FB s, and the clearness of visual field were compared between these two groups. Results The type, size, and location of FB s were similar between the two groups ( P > 0.05). The average operation time for removing the FB s was significantly shorter in the transparent cap‐assisted group than in the conventional group (2.6 min vs 4.1 min, P = 0.008). Visual field was rated as “clear” in more cases in the transparent cap‐assisted group than in the conventional group (97.1% vs 25.7%, P < 0.0001). Conclusions Transparent cap‐assisted endoscopy was a safe and effective method in the management of FB s in the upper esophagus, with a shorter operation time and clearer visual field.
