Cholangiolocellular carcinoma(CoCC)was first reported by Steiner et al in 1959. CoCC resembles cholangiocellular carcinoma( CCC)grossly and presents a variety of imaging findings, which often makes preoperative diagnosis difficult. In Japan, CoCC is rare, accounting for only 0.56% of primary liver cancers. We report the results of laparoscopic liver resection (LLR)for CoCC at our institution. Among 845 liver resections(678 LLR and 167 open liver resections)performed at Kansai Rosai Hospital from 2010 to 2020, only 13 were CoCC. Eight patients underwent LLR except for 5 patients who required vascular reconstruction and lymph node dissection. Median age was 71 years (55-77), gender was male/female(7/1), stage was Ⅰ/Ⅱ/Ⅲ/ⅣA(3/3/1/1), liver function was Child-Pugh A/B/C(7/1/0), and liver damage A/B/C(6/2/0). The preoperative diagnosis was 1 CoCC, 3 CCC and 4 HCC. The operative procedure was 3 Hr 0, 3 Hr 1 and 2 Hr 2. The operative time was 342 minutes(168-488), the blood loss was 51.3 g(0-400), and the postoperative hospital stay was 14 days(5- 53). The 5-year disease-free survival rate was 83.3%, and the 5-year overall survival rate was 85.7%. Recurrence was seen in 1 patient. The 5-year survival rate after curative resection of CoCC has been reported to be 73-83%, compared with 28- 36% for CCC. LLR for CoCC at our institution showed good perioperative results. Long-term results were comparable to those reported for liver resection. LLR for CoCC was considered an appropriate technique with good perioperative and long- term results.
