Transparent cap-assisted endoscopic management of foreign bodies in the upper esophagus: A randomized, controlled trial

Objectives Ingestion of foreign bodies (FBs) in the upper esophagus is common in South China. 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...

Description
Summary:Objectives Ingestion of foreign bodies (FBs) in the upper esophagus is common in South China. 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 FBs in the upper esophagus. Methods Adult patients suspected of FBs in the upper esophagus based on the history of FBs ingestion, symptoms, and barium contrast examination were screened for the study between March 1, 2009 and December 31, 2010. Seventy patients with endoscopic‐confirmed FBs 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 FBs, the operation time for removing the FBs, and the clearness of visual field were compared between these two groups. Results The type, size, and location of FBs were similar between the two groups (P > 0.05). The average operation time for removing the FBs 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
