Vagotogenic cholecystitis.

Truncal vagotomy provokes acute cholecystitis in the stone-containing gallbladder of dogs. An apparently similar sequence has been fortuitously observed in three patients. These circumstances suggest that where cholelithiasis is encountered in a clinical situation in which truncal vagotomy is performed, cholecystectomy or stone removal and cholecystostomy be done as a synchronous adjunctive procedure.
