Strategy for Removing an Impacted Enterolith using Double-Balloon Enteroscopy in Crohn's Disease.

: An enterolith in Crohn's disease is an uncommon but serious condition because it can cause intestinal obstruction. Endoscopic treatment to remove the enterolith is attempted first, but is sometimes difficult owing to poor accessibility of the endoscope. In such cases, surgical treatment is inevitable. We successfully overcame poor accessibility and removed an enterolith using double-balloon enteroscopy. We describe our method below and suggest several helpful techniques.

Conclusions: Patients with Crohn's disease sometimes have a history of intestinal stricture, which can cause intestinal obstruction by enterolith-related impaction.Endoscopic treatment is the first choice to remove an enterolith, but is sometimes difficult.We successfully removed an enterolith using double-balloon enteroscopy and employing several helpful techniques.
