Objective To inquire into the curative effects of combination of laproscopic cholecystomy and laparoscopic transcystic duct common bile duct exploration on cholelithiasis, cholecystolithiasis and cho-ledocholith. Methods The clinical data of 19 cases were retrospectively analyzed from Sep. 2006 to Jan.2009. Results All the operations were performed successfully. The operative time was 60～120 min, the drainage time was 3～5 d, and the postoperative hospitalization time 4～7 days. All of the patients were fol-lowed up from 3 to 6 months. No complications occurred. Conclusion Laparnscopic transcystic biliary duct exploration is safe, feasible and worth generalizing.

Hepatocellular carcinoma (HCC) is a common malignant tumor with poor prognosis, and surgical resection is the preferred method for the treatment of HCC, but it has a limited therapeutic effect on advanced HCC, while systemic treatment plays an important role in the treatment of advanced unresectable HCC. This article summarizes the advances in systemic therapy for unresectable liver cancer in China and globally in recent years, including a variety of tyrosine kinase inhibitors (sorafenib, lenvatinib, regorafenib, and cabozantinib) and immune checkpoint inhibitors (atezolizumab, pembrolizumab, and nivolumab). The analysis shows that for patients with unresectable HCC, systemic therapy can prolong the survival time of patients to a certain extent, and combined treatment regimen has become a new research hotspot. Individualized systemic treatment strategies will be further explored in the future.
