N/A Seventeen cases of microscopically proven peripheral cholangiocellular carcinoma(CCC) during 4 year period from June 1989 to June 1993 were reviewed. They comprised 9 men and 8 women with an average age of 50 years (range '. 37 to 62 years). The overall incidence of peripheral CCC in association with hepatolithiasis was 3.5% (9 in 258) and 9 out of 17 cases of peripheral CCC were combined with intrahepatic stones. The incidence of accurate preoperaive diagnosis was 41% due to low index of suspicion. Peripheral CCC developed in 2 patients with hepatolithiasis who underwent CBD exploration and left lateral segmentectomy 2 and 3 years later respectively. Their residual stones were completely removed by choledochoscopy after the operations. The resectability of 17 peripheral CCC was 47%(8 out of 17). The growth pattern of peripheral CCC was mass forming type in 6 cases and infiltra- tive type in 2 cases. Four patients with mass forming type died within 1 year because of tumor recurrence. One patient with infiltrative type survives 41 months after resection with- out any evidence of recurrence. (Korean J Gastroenterol 1994; 26: 987 994)
