[Symptoms of cholelithiasis following cholecystectomy; possibly a second gallbladder].

Three patients with cholelithiasis were found to possess a duplicate gallbladder. A 48-year-old woman continued to have symptoms one year after cholecystectomy, a 69-year-old woman had symptoms even though her gallbladder had been removed 40 years before, and in a 29-year-old woman a second gallbladder was found during cholecystectomy. In all three patients, the second gallbladder was removed as well, after which they recovered. The differential diagnosis of persistent symptoms following cholecystectomy should also consider the possible presence of an accessory gallbladder.
