An intraluminal surgical approach to the management of gastric bezoars

Abstract

Trichobezoars are difficult to remove endoscopically, often cause nausea and vomiting, and can result in small-bowel obstruction. A patient with a trichobezoar presented to our clinic with symptoms of partial small-bowel obstruction. Multiple attempts at flexible endoscopic removal were unsuccessful. Two large-diameter percutaneous gastrostomies with an inflatable balloon and distal foam-rubber stent to assure intragastric positioning were introduced under general anesthesia. Visualization was provided by a 0 degree panavision laparoscope placed through one of the gastrostomies. The bezoar was removed through the second gastrostomy using standard laparoscopic instruments. The patient made an uneventful recovery. This is the first reported case of percutaneous removal of a trichobezoar. We conclude large-diameter gastrostomies may serve as a port of access for numerous other intraluminal procedures.
