Abstract

BACKGROUND:

Bolus impaction in the esophagus is a common indication for emergency endoscopy. The aim of this study was to determine the most common causes of esophageal bolus impaction.

METHODS:

In this retrospective study, data of 54 patients (41 male, 13 female) with bolus impaction in the esophagus were analyzed. Type and localization of the bolus and the endoscopic extraction tool used were evaluated. In 48 of 54 patients (89%), biopsy samples were taken of the esophagus for histological examination.

RESULTS:

Mean age of the patients was 53 ┬▒ 20 years. Fourteen of 54 patients (26%) had experienced bolus impaction previously. Meat bolus (n = 35, 65%) was the most common cause of esophageal obstruction. In most cases, boluses were found in either the distal (n = 31) or the proximal (n = 18) esophagus. In 22 patients (41%), the bolus was pushed into the stomach by the endoscope. In most other cases the bolus, including foreign bodies, could be removed with the 5-arm polyp grasper or alligator forceps. Main causes of bolus impaction were eosinophilic esophagitis (n = 10) or reflux disease with or without peptic stenosis (n = 10), respectively.

CONCLUSION:

Bolus impaction is frequently correlated with eosinophilic esophagitis and reflux esophagitis; therefore, diagnostic workup should include esophageal biopsy sampling.
