From January in 1984 to May in 1995, we performed laparoscopy for 1342 patients and were able to observe gallbladders in 1278 cases. Among them, 11 patients (0.86%) were found to have ectopic liver tissue on serosal surface of the gallbladder. These cases were composed of 3 male and 8 female with age of 18 to 62 years. There were no symptoms relevant to the ectopic liver tissues. They were less than 15 mm in diameter, and were stained greenish by intravenous ICG injections similarly as the liver. Ten of 11 cases had single ectopic tissue and 1 case with two tissues.
