A case of acute liver failure caused by Budd-Chiari syndrome salvaged by brain-dead donor liver transplantation.

A 24-year-old man was admitted to our hospital with abdominal distension. He was found to have acute liver failure and diagnosed with Budd-Chiari syndrome based on angiography and liver biopsy. Liver transplantation was deemed necessary when angiography showed extensive thrombotic occlusion of the hepatic veins and liver biopsy revealed submassive hepatic necrosis. The patient was found to have the JAK2V617F mutation, indicating a myeloproliferative neoplasm as the background disease. He developed hepatic encephalopathy but remained conscious on on-line hemodiafiltration. Brain-dead donor liver transplantation was performed on hospital day 30. Since then, the patient has remained well.

Two cases of portal-systemic encephalopathy caused by multiple portosystemic shunts successfully treated with percutaneous transhepatic obliteration.

BACKGROUND: Portal-systemic encephalopathy is a hepatic encephalopathy caused by portosystemic shunts and is a poor prognostic factor for cirrhotic patients. Percutaneous transhepatic obliteration is an option for controlling portal-systemic encephalopathy. We report two cases of portal-systemic encephalopathy that were successfully controlled with percutaneous transhepatic obliteration. CASE PRESENTATION: (Case 1) A 70-year-old woman experienced repeated portal-systemic encephalopathy due to a mesocaval shunt and a paraumbilical vein. She underwent percutaneous transhepatic obliteration with coils and 5% ethanolamine oleate-iopamidol. After treatment, portal-systemic encephalopathy became controllable. (Case 2) A 60-year-old man experienced repeated portal-systemic encephalopathy due to a left gastric vein shunt, a shunt from the posterior branch of the intrahepatic portal vein to the inferior phrenic vein, and a paraumbilical vein. He underwent percutaneous transhepatic obliteration of three portosystemic shunts with coils, 5% ethanolamine oleate-iopamidol, and N-butyl-2-cyanoacrylate. After treatment, the portal-systemic encephalopathy became controllable. CONCLUSIONS: Percutaneous transhepatic obliteration is particularly effective in cases involving multiple and complex portosystemic shunt pathways; however, percutaneous transhepatic obliteration is an invasive treatment, and its indications should be carefully considered. These cases will serve as a reference for successful treatment in the future cases.

Unresectable primary hepatic adenosquamous carcinoma successfully treated with systemic and transcatheter hepatic arterial injection chemotherapies followed by conversion surgery: a case report and literature review.

BACKGROUND: Primary hepatic adenosquamous carcinoma (ASC) is a type of tumor that has the features of both adenocarcinoma and squamous cell carcinoma (SCC). The prognosis for patients with ASC is poor, as the chemotherapy has been ineffective so far. CASE PRESENTATION: Here, we report a case of a 62-year-old male patient who presented with high fever. The tumor marker levels were high, and abdominal dynamic computed tomography showed a liver tumor and distant lymph node metastases. Upon further investigation, needle biopsy of the liver tumor showed a primary hepatic SCC. Because the SCC was unresectable, the patient was treated with tegafur/gimeracil/oteracil (S-1) and transcatheter hepatic arterial injection (TAI) of cisplatin. After chemotherapy, a surgical resection performed on the remaining liver tumor, made the patient cancer-free. After the operation, the liver tumor was confirmed as primary hepatic ASC. Subsequently, the patient was administered postoperative adjuvant chemotherapy, which prevented its recurrence. CONCLUSIONS: Due to the lack of an effective treatment for primary hepatic ASC, its prognosis is poor. Here, we suggest that a chemotherapy combination of 5-fluorouracil (S-1) and cisplatin along with conversion surgery might be an effective way for treating primary hepatic ASC. Our experience from this case shall be valuable to clinicians around the world involved in the treatment of primary hepatic ASC.

Balloon-occluded retrograde transvenous obliteration for gastric varices improves hepatic functional reserve in long-term follow-up.

BACKGROUND AND AIM: Balloon-occluded retrograde transvenous obliteration (BRTO) has been widely adopted for the management of gastric fundal varices (GVs). There are a few reports that BRTO leads to the improvement of mid-term and long-term hepatic functional reserve (HFR). We retrospectively investigated the long-term effect on HFR and prognosis among patients who had undergone BRTO for GVs. METHODS: This single-center, retrospective study included 57successful patients out of 60 patients who underwent BRTO for GVs from December 2005 to September 2018. We examined the indicators of HFR (e.g., encephalopathy and ascites statuses, serum total bilirubin and albumin levels, % prothrombin time, and Child-Pugh and albumin-bilirubin [ALBI] scores) during 3 years of follow-up after BRTO. We analyzed survival using the Kaplan-Meier method and identified the independent prognostic factors via multivariate analyses. RESULTS: GVs disappeared in all patients who were successfully treated by BRTO. At 3 years after BRTO, serum albumin levels were significantly elevated (from 3.3 to 4.0 g/dL, P = 0.008), while Child-Pugh and ALBI scores were significantly decreased (from 7.0 to 5.7, P = 0.043, and from -1.94 to -2.60, P = 0.006, respectively). The median survival time among all patients was 2207 days; the survival rates after BRTO were 87.0% at 1 year, 81.8% at 3 years, 67.3% at 5 years, and 44.1% at 10 years. Multivariate analyses revealed that ascites, hepatic encephalopathy, and malignant neoplasms were independently associated with poor prognosis. CONCLUSION: BRTO for GVs has a favorable effect on long-term HFR.

[A case of liver abscess caused by hypermucoviscous Klebsiella pneumoniae with septic pulmonary embolism].

A 69-year-old man consulted a local doctor because of a chief complaint of fever and anorexia. CT showed a giant liver mass of the right hepatic lobe and multiple pulmonary nodules. The patient was admitted to our hospital. We punctured the liver mass, obtaining pus, and as gram-negative bacilli were detected from both blood and pus cultures, a liver abscess with septic pulmonary embolism was diagnosed. Following a positive string test, we identified the pathogenic bacteria as hypermucoviscous Klebsiella pneumoniae, which is highly invasive to the tissues. The patient showed improvement following the administration of an antimicrobial agent (Meropenem) and multiple abscess drainage procedures.
