About 20%-30% of newly diagnosed hepatocellular carcinoma (HCC) patients are surgically feasible due to a variety of reasons. Active conversion therapy may provide opportunities of surgery for these patients. Nevertheless, the choice of surgical procedure is controversial after successful conversion therapy. We report a patient with HCC who underwent successful laparoscopic right trisectionectomy after conversion therapy with portal vein embolization and transarterial chemoembolization.
A 67-year-old male patient presented to our hospital with epigastric distention/ discomfort and nausea/vomiting for more than 1 mo. Contrast-enhanced computed tomography scan of the abdomen demonstrated multiple tumors (the largest was ≥ 10 cm in diameter) located in the right liver and left medial lobe, and the left lateral lobe was normal. The future remnant liver (FRL) of the left lateral lobe accounted for only 18% of total liver volume after virtual resection on the three-dimensional liver model. Conversion therapy was adopted after orally administered entecavir for antiviral treatment. First, the right portal vein was embolized. Then tumor embolization was performed via the variant hepatic arteries. After 3 wk, the FRL of the left lateral lobe accounted for nearly 30% of the total liver volume. Totally laparoscopic right trisectionectomy was performed under combined epidural and general anesthesia. The in situ resection was performed via an anterior approach. The operating time was 240 min. No clamping was required during the surgery, and the intraoperative blood loss was 300 mL. There were no postoperative complications such as bile leakage, and the incision healed well. The patient was discharged on the 8th postoperative day. During the 3-mo follow-up, there was no recurrence and obvious hyperplasia of residual liver was observed. Alpha-fetoprotein decreased significantly and tended to be normal.
Due to the different biological characteristics of the liver cancer and the pathophysiological features of the liver from other organs, the conversion treatment should take into account both the feasibility of tumor downstaging and the volume and function of the remnant liver. Our case provides a reference for clinicians in terms of both conversion therapy and laparoscopic right trisectionectomy.
Core Tip: Only 20%-30% of newly-diagnosed hepatocellular carcinoma (HCC) patients are feasible for surgical resection. We report a HCC patient who underwent successful laparoscopic right trisectionectomy after conversion therapy with portal vein embolization and transarterial chemoembolization. There are few reports in the literature. Our case provided reference for clinicians in terms of both conversion therapy and laparoscopic right trisectionectomy.
