[Two Cases of Elderly Patients with Giant Intrahepatic Cholangiocarcinoma Treated with Multidisciplinary Therapy including Ablation Therapy].

Case 1 consisted of an 86-year-old male diagnosed with intrahepatic cholangiocarcinoma(ICC), approximately 11 cm in diameter, at segment S7/8 of the liver. A total of 4 percutaneous radiofrequency ablations(PRFA)and 3 hepatic arterial infusion chemotherapies(HAIC)of 5-FU were performed. He died after developing lung metastases 27 months after the initial treatment. Case 2 was an 85-year-old female diagnosed with ICC, 8 cm in diameter, at the posterior segment of the liver, with lymph node metastasis. She underwent HAIC of 5-FU and S-1 as well as gemcitabine-based systemic chemotherapy. The main tumor developed 10 months after the initial treatment, and PRFAs were subsequently performed twice for the main lesion. Although the tumor markers gradually decreased, she died of jaundice 33 months after the initial treatment. As one of the multidisciplinary therapies for the giant ICC, ablation therapy may be safe and effective in elderly patients.

[Clinical Study of Peritoneovenous Shunt for Patients with Refractory Ascites Accompanied with Hepatocellular Carcinoma].

BACKGROUND: Hepatic ascites may cause a variety of symptoms and may progress deterioration of quality of life. Peritoneovenous shunt(PV shunt)is technically feasible and useful for the treating of refractory ascites, but sometimes it can be associated with fatal complications. This retrospective study aimed to investigate the effect of PV shunt for patients with refractory ascites, including hepatocellular carcinoma(HCC)patients. SUBJECTS: Between January 2010 and December 2021, we retrospectively analyzed 54 consecutive patients(including 35 HCC patients)with refractory ascites who underwent PV shunt at our institute. RESULTS: Body weight loss after surgery was observed in 39 of the 54 cases, and eGFR improved in 34 cases. There were 17(31.5%)in-hospital deaths. Cases with present of portal vein tumor thrombus, Child-Pugh classification C, ALBI score≥-1.12, or serum total bilirubin≥1.7 mg/dL were significantly higher in hospital-death group than in the discharged from the hospital group. CONCLUSIONS: PV shunt for HCC patients with refractory ascites may be effective for improvement of renal function and symptoms. However, indications for PV shunt should be carefully considered for high-risk patients with adequate preoperative evaluation.

[A Rapid Clinical Course of Pulmonary Embolism Associated with Gallbladder Mucinous Carcinoma].

A 51-year-old woman with edema of the lower extremities and exertional dyspnea was admitted to our hospital. Enhanced CT revealed thrombi of the pulmonary artery and a gallbladder tumor. After anticoagulation therapy was started on her, anemia and jaundice progressed; thus, endoscopic retrograde cholangiopancreatography(ERCP)was performed on suspicion of bleeding from a gallbladder tumor. We performed cholecystectomy in emergency to control the anemia due to hemorrhage. Oxygenation suddenly worsened intraoperatively, maintaining her blood pressure became difficult, and the patient decompensated. The histopathological diagnosis was gallbladder mucinous carcinoma with severe lymphatic invasion. Although an autopsy was not performed, pulmonary artery embolism derived from a tumor embolus was the suspected cause of the sudden change of the clinical course.
