Pharmacobezoar in an obese patient with intragastric balloon: a case revealed at endoscopy.

Pharmacobezoar formation is a very rare complication that occurs in cases of altered gastrointestinal motility or to a background of disturbed anatomy of the gastrointestinal tract. The case of an obese and depressed patient treated by an intragastric balloon for weight loss, who was revealed to have a pharmacobezoar during endoscopy for early balloon removal, is presented. The possible causes of pharmacobezoar formation in such a patient treated with an intragastric balloon are discussed. [ABSTRACT FROM AUTHOR]
