Therapeutic strategies including B-RTO with a microballoon catheter were useful to achieve a favorable outcome in patients with gastric fundal varices especially in those manifesting Child-Pugh class-A liver damage and/or those without hepatocellular carcinoma complication.

NS5A-Y93H mutation was associated with sex, serum AFP levels, and IL28B-related gene polymorphisms in patients infected with genotype 1b HCV. The indications for NS5A inhibitor use should be determined based on these factors, since mutant strains seem to be sensitive to interferon.

This study sought to clarify the usefulness of lenvatinib for patients with unresectable hepatocellular carcinoma (HCC). Methods The subjects were 69 patients with HCC receiving lenvatinib; the median age was 73 years, and 14 and 67 patients had been previously treated with regorafenib and/or sorafenib and therapies without molecular-targeted agents, respectively. Therapeutic efficacy was evaluated using contrast-enhanced CT images obtained 4-8 weeks after the start of lenvatinib and the middle-term outcome using Kaplan-Meier method. Results The baseline Child-Pugh scores were 5, 6 and 7 in 31, 32 and 6 patients, respectively, and the modified albumin-bilirubin (mALBI) grades were 1, 2a and 2b in 20, 20 and 29 patients, respectively. The Barcelona Clinic Liver Cancer (BCLC) stages following downsizing after prior treatment were A, B and C in 17, 22 and 30 patients, respectively. The therapeutic efficacy was evaluated in 54 patients, and the percentages of patients achieving CR, PR, SD and PD were 3.7%, 44.4%, 37.0%, and 14.8%, respectively. The ALBI scores deteriorated significantly between 4 and 12 weeks after the start of therapy, compared with the baseline. The cumulative survival rates at 48 weeks were significantly higher among patients achieving CR/PR (95.5%) than among those showing no response (54.3%). Multivariate analyses revealed that the BCLC stages and the serum AFP levels were significantly associated with therapeutic efficacy, while the mALBI grade was associated with the middle-term outcome.

Bleeding from rectal varices was controlled satisfactorily by the therapeutic strategy of selecting EVL, EIS or B-RTO as an additional therapy according to the size and hemodynamics of the varices.

Miriplatin is a useful and safe agent for TACE in patients with HCC stage I or II and/or JIS score 0 or 1 only when radiofrequency ablation and liver resection cannot be performed.

For HCC patients, although miriplatin-TACE was superior to epirubicin-TACE in the short term, it proved inferior to the latter in the long term. The merits of TACE using miriplatin should be further investigated, because adverse effects appear to be minimal after miriplatin administration.

A 73-year-old man with liver cirrhosis due to hepatitis C virus infection was admitted to our hospital because of massive bleeding from external varices. Colonoscopic examination revealed that giant anorectal varices had developed between the anus and rectal ampulla, and had ruptured at the perianal site. On three-dimensional computed tomography imaging, the feeding and drainage vessels of the varices were identified as the inferior mesenteric vein and right inferior hemorrhoidal vein, respectively. Endoscopic therapies were not employed for the bleeding varices, because the blood flow volume of the feeding vessel was extremely large. Balloon-occluded retrograde transvenous obliteration (B-RTO) was therefore carried out through the drainage vessels. The variceal blood flow disappeared after B-RTO therapy, and the varices decreased in size with thrombus formation verified by colonoscopy. Bleeding from the external varices also ceased. B-RTO therapy may be an effective approach for giant anorectal varices presenting as a complication in liver cirrhosis patients in whom the main drainage vessels can be determined.

AimPortosystemic shunts aggravate liver function by decreasing portal blood flow. The usefulness of balloon‐occluded retrograde transvenous obliteration (B‐RTO), a standardized therapeutic procedure for gastric fundal varices (GFV), for the improvement of liver function was evaluated in cirrhotic patients with or without varices.MethodsThe subjects were 161 patients with portosystemic shunts. A balloon catheter was inserted into the shunts, followed by the injection of 5% ethanolamine oleate through the catheter under balloon inflation. The balloon was kept inflated for 6 to 48 h.ResultsB‐RTO was performed as a therapy for GFV in 112 patients and for the improvement of liver function in 49 patients. The targets were splenorenal shunts in 104 patients (93.6%) in the former group and 33 patients (67.3%) in the latter group, and the procedures were successfully completed in 109 (97.3%) and 39 (79.6%) patients, respectively. In both groups, the serum albumin levels were increased and the serum ammonia levels were decreased at more than 1 month after the procedures, compared with the baseline levels, whereas significant improvements in the Child–Pugh scores and prothrombin times were only seen in the latter group. In these patients, the portal blood flows evaluated using Doppler ultrasound were increased at 1 week after the procedures, compared with the baseline levels.ConclusionsB‐RTO is a useful therapeutic procedure for improving liver function even in patients without GFV by increasing the portal venous flow with successfully targeted, uncommon portosystemic shunts.
