RESUMO
Objective Nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH) treatment guidelines recommend sodium glucose cotransporter 2 inhibitor (SGLT2I) and glucagon-like peptide-1 agonist (GLP-1A) therapy in patients with type 2 diabetes mellitus (T2DM). SGLT2I improves the pathological condition of NAFLD/NASH in T2DM patients. However, cases of rebound during long-term SGLT2I treatment have been reported. This study investigated the efficacy of SGLT2I and GLP-1A combination therapy in diabetic patients with NAFLD by examining changes in computed tomography (CT)-based body composition and clinical outcomes. Methods Fifteen patients (5 men/10 women) with T2DM-associated NAFLD who had not responded to SGLT2I treatment and were being treated with GLP-1A combination therapy were included. Changes in the liver function, visceral adipose tissue index (VATI), and subcutaneous adipose tissue index (SATI) were compared using CT to evaluate the body composition. Results SGLT2I significantly improved alanine aminotransferase (28.0 to 13.0 IU/L), alkaline phosphatase (250.0 to 77.0 IU/L), and gamma glutamyl transpeptidase (23.0 to 12.0 IU/L) levels. The body mass index (BMI) decreased from 25.7 to 25.2 kg/m2. A CT-based analysis showed a significant improvement in SATI (80.9 to 66.1, p=0.002), with no significant change in VATI (53.2 to 51.5). GLP-1A addition improved the BMI (25.2 to 23.5 kg/m2) and hemoglobin A1c (6.5% to 6.2%, p=0.001). A further analysis revealed additional improvement in SATI (66.1 to 56.6, p=0.007) and a significant decrease in VATI (51.5 to 48.3, p=0.001). Conclusion SGLT2I and GLP-1A combination therapy improved the liver function, body composition, and glycemic control in diabetic patients with NAFLD/NASH, as well as SATI and VATI. The optimal timing of combination therapy remains to be determined.
RESUMO
BACKGROUND/AIM: Atezolizumab plus bevacizumab (Atez/Bev) therapy is extremely effective and has a high response rate in hepatocellular carcinoma (HCC) treatment. This study investigated the efficacy of adding locoregional therapy with Atez/Bev for non-complete response (CR) HCC cases. PATIENTS AND METHODS: Twenty-eight HCC patients without CR during Atez/Bev therapy received locoregional therapy, and treatment efficacy was evaluated based on the modified RECIST criteria. RESULTS: The study included 23 male and five female participants with a mean age of 73.5 years. In the Atez/Bev and locoregional combination therapy effective group, both transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) were combined in all patients. A significant reduction in neutrophil-to-lymphocyte ratio (NLR) was observed after adding locoregional therapy (p=0.039). Moreover, a combination of TACE and RFA was performed in all patients of the CR group. When assessing the add-on effect of the combination of TACE and RFA in the progressive disease (PD) group, seven patients were found to achieve non-PD. For patients who did not achieve PD, a significant NLR reduction was noted after the addition of locoregional therapy. CONCLUSION: Adding locoregional therapy such as TACE/RFA was found to exert an effect even in non-CR patients who had received Atez/Bev therapy. A reduction in NLR after locoregional therapy was noted. Even when a response is not obtained during Atez/Bev therapy, it is important to avail the option to add locoregional therapy, as it may contribute to improved prognosis via immune modulation with tolerable adverse reactions.

This study aimed to investigate the risk factors for difficult endoscopic hemostasis in patients with colonic diverticular bleeding and to evaluate the efficacy and safety of transcatheter arterial embolization (TAE) for colonic diverticular bleeding. This study included 208 patients with colorectal diverticular hemorrhage. The non-interventional radiotherapy group consisted of patients who underwent successful spontaneous hemostasis (n = 131) or endoscopic hemostasis (n = 56), whereas the interventional radiotherapy group consisted of patients who underwent TAE (n = 21). Patient clinical characteristics were compared to identify independent risk factors for the interventional radiotherapy group. Furthermore, the hemostasis success rate, rebleeding rate, complications, and recurrence-free survival were compared between patients who underwent endoscopic hemostasis and those who underwent TAE. Bleeding from the right colon (odds ratio [OR]: 7.86; 95% confidence interval [CI]: 1.6-38.8; P = .0113) and systolic blood pressure <80 mm Hg (OR: 0.108; 95% CI: 0.0189-0.62; P = .0126) were identified as independent risk factors for the interventional radiology group. The hemostasis success rate (P = 1.00), early rebleeding rate (within 30 days) (P = .736), late rebleeding rate (P = 1.00), and recurrence-free survival rate (P = .717) were not significantly different between the patients who underwent TAE and those who underwent endoscopic hemostasis. Patients in the TAE group experienced more complications than those in the endoscopic hemostasis group (P < .001). Complications included mild intestinal ischemia (19.0%) and perforation requiring surgery (4.8%). Patients who required interventional radiotherapy were more likely to bleed from the right colon and presented with a systolic blood pressure of <80 mm Hg. TAE is an effective treatment for patients with colonic diverticular hemorrhage that is refractory to endoscopic hemostasis. However, complications must be monitored carefully.

Aim of the study: Owing to the association between non-alcoholic fatty liver disease (NAFLD) and dyslipidemia, there is a need for new treatment strategies to manage both conditions concomitantly. Our aim in this study was to evaluate the effectiveness of pemafibrate in alleviating dyslipidemia-associated NAFLD, including the evaluation of its effects on liver function and body composition. Material and methods: The study sample included 67 patients with dyslipidemia-associated NAFLD (29 males, mean age 65.7 years [range, 58.4-73.7]) who were administered pemafibrate continuously for a period of at least 12 months, between June 2019 and January 2022. Outcomes were the change in body composition indices (visceral adipose tissue index - VATI, subcutaneous adipose tissue index - SATI, and skeletal muscle index - SMI), lipid biochemistry, and liver function, reserve, and fibrosis score, from baseline to the 12-month time point of pemafibrate treatment. Results: Pemafibrate treatment improved liver function (alanine aminotransferase, aspartate aminotransferase, g-glutamyl transpeptidase, and alkaline phosphatase), and lipid biochemistry (triglycerides and total cholesterol). Improvements in ferritin and hepatic reserve (Mac-2 binding protein, albumin-to-bilirubin score, and NAFLD fibrosis score) were also observed, as well as a decrease in SATI. Conclusions: Pemafibrate improved dyslipidemia, liver function, and hepatic reserve. The positive effects of pemafibrate on body composition likely contributed to the improvements in liver function. Longer-term treatment may be necessary to influence VATI and thus to further evaluate the relationship between improved body composition and NAFLD with pemafibrate treatment.
RESUMO
BACKGROUND/AIM: The standard of care for patients with colorectal cancer and liver metastases, who fail to respond to systemic chemotherapy has not yet been established. Therefore, we investigated the prognostic value of transarterial chemoembolization (TACE) using irinotecan-loaded drug-eluting beads (DEBIRI) in treating liver metastases due to colorectal cancer. PATIENTS AND METHODS: Forty-six patients with colorectal cancer and unresectable liver metastases, who received systemic chemotherapy beyond the third line at our hospital between July 2014 and April 2020 were analyzed. They were divided into two groups: 1) Seventeen patients who received TACE with DEBIRI, and 2) twenty-nine patients who did not receive TACE. RESULTS: The median age was 68 years (range=37-85 years), and the male-to-female ratio was 29:17. The primary sites were the cecum in six cases, ascending colon in seven cases, transverse colon in two cases, descending colon in three cases, sigmoid colon in 14 cases, and rectum in 14 cases. All patients had received at least two prior systemic chemotherapy regimens including oxaliplatin-based and irinotecan-based regimens, and trifluridine tipiracil hydrochloride (38 patients) or regorafenib (12 patients) as the third line or beyond (overlap). Median survival was 272 days overall, 416 days in the TACE group, and 229 days in the non-TACE group, with significantly better survival in the TACE group (p=0.0126). CONCLUSION: TACE with DEBIRI may improve the prognosis of patients with liver metastases from unresectable colorectal cancer. We suggest that TACE with DEBIRI should be highly considered, especially in patients in whom liver metastasis may be a prognostic factor.

Background: Microwave ablation (MWA) is a standard percutaneous local therapy for hepatocellular carcinoma (HCC). Next-generation MWA is reported to create a more spherical ablation zone than radiofrequency ablation (RFA). We compared the ablation zone and aspect ratio of two 2.45 GHz MWA ablation probes; Emprint® (13G) and Mimapro® (17G). We compared the ablation zone to the applied energy after MWA in patients with hepatocellular carcinoma (HCC). Furthermore, we investigated local recurrence. Materials and Methods: We included 20 patients with HCC, with an average tumour diameter of 33.2 ± 12.2 mm, who underwent MWA using Emprint®, and 9 patients who underwent MWA using Mimapro® with an average tumour diameter of 31.1 ± 10.5 mm. Both groups underwent the same ablation protocol using the same power settings. The images obtained after MWA showed the treatment ablation zone and aspect ratio, which were measured and compared using three-dimensional image analysis software. Results: The aspect ratios in the Emprint® and Mimapro® groups were 0.786 ± 0.105 and 0.808 ± 0.122, respectively, with no significant difference (p = 0.604). The ablation time was significantly shorter in the Mimapro® group than in the Emprint® group, and there was no significant difference in the frequency of popping or the ablation volume. There were no significant differences in local recurrence between the two groups. Conclusion: There was no significant difference in the aspect ratios of the ablation diameter, and the ablation zone was almost spherical in both cases. Mimapro® at 17G was less invasive than Emprint® at 13G.
RESUMO
BACKGROUND/AIM: Ablating a spherical area during hepatocellular carcinoma ablation therapy is a very important issue. We aimed to determine the ablation area of bovine liver using various radiofrequency ablation (RFA) protocols. MATERIALS AND METHODS: Bovine liver (1-2 kg) was placed in an aluminum tray, which was punctured with STARmed VIVA 2.0 17-gauge (G) and 15-G electrodes using a current-carrying tip. Under the step-up or linear method, with an ablation time up to one break and RFA output stop, the size of the color change area (representing the thermally coagulated area) of the bovine liver was measured along the vertical and horizontal axes, and the ablated volume and total heat generated were calculated. RESULTS: 5-W per minute increases protocol resulted in greater horizontal and vertical diameters of the ablated area than 10-W per minute increases protocol under the step-up method. For 5-W and 10-W per minute increases under the step-up method, the aspect ratio was 0.81 and 0.67 with a 17-G electrode, and 0.73 and 0.69 with a 15-G electrode, respectively. For 5-W and 10-W increases under the linear method, the aspect ratio was 0.89 and 0.82, respectively. Sufficient ablation was obtained, with vertical and horizontal diameters of 50 mm and 43.50 mm, respectively. Although the ablation time was long, the watt output value at the break and average watt value were low. CONCLUSION: Gradual increase in output (5 W) using the step-up method yielded a more spherical ablation area, and longer ablation time in the linear method with a 15-G electrode could result in a more spherical ablation area in real clinical practice in humans. Future studies should examine concerns regarding long ablation times.

BACKGROUND/AIM: Lenvatinib is available as a molecular target agent for hepatocellular carcinoma (HCC). In this study, we investigated the popping phenomena in patients with HCC who underwent radiofrequency ablation (RFA) after taking lenvatinib. PATIENTS AND METHODS: Fifty-nine patients with HCC between 21-30 mm in diameter and no history of systemic treatment were enrolled in the study. The patients underwent RFA using a VIVA RFA SYSTEM with an ablation tip of 30 mm in length. For the initial lenvatinib administration, 16 patients had an adequate course of treatment and were treated with RFA as add-on therapy (combination group). The other 43 patients were treated by RFA monotherapy (monotherapy group). The popping frequency during RFA was recorded and compared. RESULTS: Popping frequency in the combination group (RFA combined with lenvatinib) was significantly higher than that in the monotherapy group. There was no significant difference between the combination group and the monotherapy group in ablation time, maximum output level, tumour temperature after ablation, or initial resistance value. CONCLUSION: Popping frequency was significantly higher in the combination group. It is possible that the intra-tumour temperature increased rapidly during RFA in the combination group due to the inhibitory effect of lenvatinib on tumour angiogenesis, leading to the occurrence of popping. Further studies are needed to investigate popping after RFA, and precise protocols need to be developed.

BACKGROUND: Transarterial chemoembolization (TACE) is the standard treatment for Barcelona Clinic Liver Cancer (BCLC)-B hepatocellular carcinoma (HCC). A novel glass membrane emulsification device (GMD) produces a high percentage of water/oil emulsions with homogeneous and stable droplets. There are few reports on the efficacy of GMD-conventional-TACE (GMD-c-TACE); therefore, we aimed to evaluate the effectiveness of GMD-c-TACE. METHODS: Seventy-one patients with HCC with tumor diameter <5 cm who underwent c-TACE with and without GMD were included in this study to investigate local recurrence and hepatic functional reserve. RESULTS: The local recurrence rates of TACE without GMD were 3.0% at 6 months, 16.7% at 12 months, and 35.0% at 18 months, around where it plateaued. In contrast, the local recurrence rates in the GMD-c-TACE group were 0.0% at 12 months and 15.4% at 18 months, respectively. Thus, GMD-c-TAE had a significantly lower local recurrence. ALBI score of c-TACE with GMD significantly preserved hepatic reserve. Multivariate analysis showed that GMD-c-TACE could suppress local recurrence and maintain hepatic reserve. CONCLUSIONS: GMD-c-TACE allows dense lipiodol accumulation in the tumor and the attainment of good local control. Additionally, in vitro evaluation of the sustained release properties of GMD, the inhibition of the release of anticancer drugs may lead to maintain hepatic reserve. GMD-c-TACE is useful in preventing local recurrence and is expected to become the standard treatment form of c-TACE in the future.

Blood transfusion, splenectomy, and partial splenic embolization (PSE) are generally performed for thrombocytopenia in patients with cirrhosis. Recently, thrombopoietin (TPO) agonists have become available, and investigations of patients who would benefit from them are necessary. Therefore, it is important to understand the fluctuations in cytokine levels associated with PSE. Therefore, fluctuations in platelet-associated immunoglobulin G (PAIgG), interleukin 6 (IL-6), and TPO levels with PSE were analyzed in this study. The study included 110 patients with liver cirrhosis and thrombocytopenia, with the aim of improving platelet counts. Fluctuations in PAIgG, IL-6, and TPO levels were investigated. The average splenic embolization ratio was 58.0% in patients with PSE. The platelet count rose significantly from 6.95 [5.40, 8.60]â ×â 104/mL to 14.05 [10.43, 18.05]â ×â 104/mL (Pâ <â .01), IL-6 rose significantly from 3.56 [2.53, 7.33] pg/mL to 18.90 [9.17, 32.95] pg/mL (Pâ <â .01), TPO rose significantly from 0.82 [0.52, 1.21] fmol/mL to 1.58 [0.97, 2.26] fmol/mL (Pâ <â .01), and PAIgG decreased significantly from 64.20 [38.33, 118.75] ng/107 cells to 37.50 [22.25, 70.00] ng/107 cells (Pâ <â .01). On multivariate analysis of factors related to the rate of platelet increase with PSE, primary biliary cholangitis (Bâ =â 0.475, Pâ <â .01), splenic embolization ratio (Bâ =â 0.75, Pâ <â .01), IL-6 change ratio (Bâ =â 0.019, Pâ <â .01), and PAIgG change ratio (Bâ =â -0.325, Pâ <â .01) were significant. When attempting to improve thrombocytopenia with PSE, adequate splenic embolization needs to be obtained together with improvements in IL-6, PAIgG, and TPO levels. With unsatisfactory improvement in thrombocytopenia, TPO agonist administration was considered.

BACKGROUND: Mac-2-binding protein glycosylation isomer (M2BPGi), a novel noninvasive biomarker for fibrosis, is a prognostic factor for liver disease; however, its relationship with hepatic function reserve and nutritional status remains unclear. Furthermore, the cut-off value of this marker varies with the underlying liver disease. This study aims to clarify that M2BPGi can be clinically used as a hepatic function reserve marker and nutritional index without pushing the search for alternative markers to the forefront in clinical practice as an important biomarker. METHODS: Seven hundred and forty-three outpatients with chronic liver disease (CLD) were enrolled. We evaluated the relationship among M2BPGi, albumin-bilirubin (ALBI) grade, and Controlling Nutritional Status (CONUT) score as nutritional status markers. Diagnostic performance of M2BPGi values in distinguishing different modified ALBI (mALBI) grade and CONUT score were compared using receiver operating characteristic (ROC) curve analysis. RESULTS: The M2BPGi level increased with ALBI and mALBI grades. The correlation coefficient (r2) between M2BPGi and ALBI grade was 0.40 (r=0.63), indicating a positive correlation between M2BPGi and ALBI grade. The cut-off for M2BPGi to predict mALBI G1 vs. G2-G3 was 1.07, G1-2a vs. G2b-3 was 1.73, and mALBI G1-2 vs. G3 was 5.83 under the ROC curves. The cut-off for M2BPGi to predict CONUT score normal vs. light-severe was 1.60, normal-light vs. moderate-severe was 1.74, and normal-moderate vs. severe was 5.83 under the ROC curves. M2BPGi correlates with ALBI grade and is useful for diagnosing ROC analysis results, especially G2 and above. M2BPGi also correlates with the CONUT score and is useful for diagnosing ROC analysis results, especially moderate or higher. These results showed similar diagnostic performance regardless of the etiology of the background liver disease. CONCLUSIONS: Although the predictive cut-off value varied with the type of liver disease, M2BPGi was found to be a single predict biomarker of ALBI and CONUT, and thus, is an effective indicator of CLD status. Further investigation is warranted to determine the clinical utility of this marker.

BACKGROUND: Interventional radiology (IVR), including balloon-occluded retrograde transvenous obliteration (BRTO) and percutaneous transhepatic obliteration (PTO), is performed for patients with intractable hepatic encephalopathy (HE). However, information on the appropriate coil for endovascular coiling for preventing recanalization is lacking. This study aimed to compare the different types of coils for endovascular coiling used in BRTO and PTO for cases of intractable HE. METHODS: This retrospective study included patients who underwent endovascular coiling with BRTO or PTO for HE caused by portosystemic shunts. The number of coils required for complete occlusion was compared among bare, fiber, and hydrogel-coated coils, and the expansion types that close the gap between and inside the hydrogel-coated coils were also compared. RESULTS: Of 38 patients (age range, 30-86 years), 16 and 22 underwent BRTO and PTO, respectively, using bare (19 patients), fiber (8 patients), and hydrogel-coated coils (10 patients; external expansion type, 4; internal expansion type, 6). No significant differences in the size of portosystemic shunts were observed according to the type of coil. The mean number of coils required for complete occlusion varied (bare coils, 19.32; fiber coils, 18.11; hydrogel-coated coils, 10.70). Significantly fewer coils were required for endovascular coiling with hydrogel-coated coils. In the internal expansion type, a mean of 8.5 coils was required for occlusion. CONCLUSIONS: In some patients who underwent portal vein embolization, complete occlusion was not achieved with the scheduled type of coil because of slight expansion of blood vessels due to coil pressure. The findings suggested that hydrogel-coated coils were effective in endovascular coiling for HE caused by a portosystemic shunt, and internal expansion-type hydrogel-coated coils may be effective for the first-line procedure.

Background and Aims: The prognosis of acute liver failure (ALF) treated with conservative therapy is extremely poor. Histologic diagnosis at the time ALF occurs provides important clues for determining the prognosis, including indications for liver transplant. Transjugular liver biopsy (TJLB), which helps clarify the pathology of ALF, may be an effective clinical parameter that contributes to prognosis prediction, including indications for liver transplant. Methods: In this prospective study, 79 patients who underwent TJLB with ALF were enrolled between May 2002 and March 2021. The relationships between prognosis and the extent of tissue necrosis on TJLB specimens, serum parameters related to the cause, and clinical parameters were investigated. Results: Model for end-stage liver disease-sodium, hepatic encephalopathy predicting, total bilirubin, hepatocyte growth factor, ammonia, coma rate, and histologic diagnosis were identified as prognostic factors on univariate analysis. Histologically, 13 of 16 patients with massive hepatic necrosis died or had a liver transplant. On multivariate analysis, the only prognostic factor was massive hepatic necrosis. There were no treatment-related complications, and TJLB was technically successful in all patients. Conclusion: In diagnosing the cause of ALF and understanding its pathology, TJLB contributes to predicting the prognosis of ALF based on histologic findings together with liver function tests and imaging findings, and it is an important diagnostic technique for determining diagnostic and treatment eligibility, including indications for liver transplant. When determining the best timing for patient selection and liver transplant, the finding of massive hepatic necrosis on TJLB specimens at the time ALF occurred was the most important prognostic factor.
RESUMO
Introduction Transjugular liver biopsy (TJLB) is indicated for patients in whom percutaneous liver biopsy is contraindicated, such as those with hematological diseases complicated by liver dysfunction. However, the clinical utility of TJLB in this group of patients has not been thoroughly investigated. The objective of this study is to evaluate the clinical efficacy of TJLB in patients with hematological diseases complicated by liver dysfunction. Methods We analyzed the data of patients who developed liver disorders during treatment for hematological diseases at our hospital and required tissue diagnosis via TJLB. The clinical features of patients were analyzed. Results Twenty-seven patients (mean age, 60.07 years; 12 men, 15 women) requiring tissue diagnoses via TJLB after developing liver disorders while undergoing treatment for hematological diseases were enrolled. One patient with autoimmune hemolytic anemia was diagnosed with drug-induced liver injury; two patients with amyloidosis had nonalcoholic steatohepatitis; one patient with acute promyelocytic leukemia had a drug-induced liver injury; one patient with chronic myelomonocytic leukemia had liver infiltration caused by an underlying disease; three patients with idiopathic thrombocytopenic purpura had autoimmune hepatitis; four patients with malignant lymphoma had liver infiltration by the underlying disease, and one patient with multiple myeloma had liver disorder caused by disseminated intravascular coagulation. Moreover, one patient had hepatitis B reactivation, another had hepatitis E, and six patients had a drug-induced liver injury. The treatment regimen was altered in cases of liver infiltration caused by the underlying disease, and the drug was changed for patients with drug-induced liver injury. Conclusion The etiology of liver disorders in patients with hematological diseases varies widely. Therefore, histological diagnosis using TJLB is useful to determine an appropriate therapeutic strategy for underlying hematological diseases.
RESUMO
The current study aimed to compare the safety and effectiveness of self-expandable metallic stent placement among patients with extracolonic malignancy and those with colorectal cancer. Patient information, technical and clinical success rates and complication rates were compared between patients with colorectal cancer and extracolonic malignancy. The Kaplan-Meier method was used to compare the time elapsed before the onset of complications. Risk factors for re-obstruction in patients with self-expandable metallic stents were evaluated by multivariate analysis. A total of 68 patients who underwent self-expandable metallic stent placement at Saiseikai Niigata Hospital between January 2012 and September 2019 were included. The clinical success rate was significantly different between the colorectal cancer (96.6%) and extracolonic malignancy (66.7%) groups (P=0.01). The incidence of complications was significantly higher in the extracolonic malignancy group (66.7%) than in the colorectal cancer group (25.4%; P=0.02). Additionally, the time elapsed before the onset of complications was shorter in the extracolonic malignancy group than in the colorectal cancer group (P=0.0008). Risk factors for re-obstruction were higher in the extracolonic malignancy group [odds ratio, 7.76 (1.02-57.2)] than in the palliative stent placement group [odds ratio, 5.45 (1.01-29.5); P=0.04]. In extracolonic malignancy, self-expandable metallic stent placement was associated with lower clinical success rates and increased risk of complications. The time elapsed before the onset of complications was short, and extracolonic malignancy was a risk factor for re-obstruction, suggesting that the placement of self-expandable metallic stents for malignant colorectal obstruction in extracolonic malignancy is not optimal.
RESUMO
Background/Aim: Tumor biopsy are needed frequency for accurate diagnosis. However, percutaneous liver tumor biopsy presents a risk of complications such as bleeding and tumor seeding. We investigated the feasibility of liver tumor biopsy, followed by cauterization with expandable radiofrequency ablation. Patients and Methods: Tumor biopsies using a co-access needle were performed in 102 patients. Expandable radiofrequency ablation was used to ensure cauterization and hemostasis of the puncture route. We evaluated the clinical background and complications. Results: The average (±standard deviation) tumor diameter was 56.87±39.45 mm. Pathological diagnosis was possible in all cases. In 20 patients, the postoperative pathological diagnosis differed from the preoperative diagnosis. No significant anemia progression was observed in any patients after biopsy, and no peritoneal seeding was observed during a mean follow-up observation period of 18.5 months. Conclusion: Liver tumor biopsy, followed by cauterization with expandable radiofrequency ablation via a co-access needle, is safe and useful for obtaining reliable diagnoses.
RESUMO
OBJECTIVE: Tolvaptan (TVP) is an effective treatment for patients with cirrhotic ascites; however, studies have indicated that a sufficient effect is difficult to obtain in patients with hepatocellular carcinoma (HCC). This study evaluates the efficacy of TVP in patients with HCC with refractory ascites. METHODS: We retrospectively enrolled 32 patients with liver cirrhosis and refractory ascites [mean age: 74 years (range, 47-86 years), men: 78.1% (25/32)]. All patients had HCC and were treated with TVP at our hospital. A TVP responder was defined as a patient who experienced decrease in body weight by ≥1.5 kg within 1 week of treatment. Univariate and multivariate analyses were performed to evaluate clinical and laboratory predictive factors of TVP response. RESULTS: The TVP response rate was 46.9% (15/32 patients) after 1 week of treatment. HCC treatment (transcatheter arterial chemoembolization and/or radiofrequency ablation) was administered to 11/15 (73.3%) responders. In the multivariate analysis, the reduction of urine osmolality was higher in responders than nonresponders (202 mOsm/l vs. 65 mOsm/l, P = 0.040), and the tumor stage (P = 0.043) was worse in nonresponders. Multivariate Cox proportional hazards regression analysis indicated a significantly better prognosis among responders than among nonresponders (P < 0.01). CONCLUSION: The HCC tumor stage and the reduction in urine osmolality can predict the efficacy of TVP in patients with refractory ascites complicated with HCC. TVP may allow therapeutic intervention for HCC and improve prognosis, even in patients with Child-Pugh class C.

Objective Rifaximin has become available for treating hyperammonemia in patients with hepatic encephalopathy. This study analyzed the changes in the body composition and nutritional status after long-term rifaximin therapy. Methods Twenty-one patients who underwent rifaximin therapy at 1,200 mg/day for more than 24 weeks were evaluated for the changes in the controlling nutritional status (CONUT) scores for the nutritional assessment, albumin-bilirubin (ALBI) scores for the liver function assessment, and skeletal muscle index (SMI) for the body composition assessment. Results There were 17 men and 4 women, with a mean age of 67.14±8.32 years. Eleven cases had a portosystemic shunt (52.3%), and 10 had hepatocellular carcinoma (47.6%). The Child-Pugh class was A in 9 cases (42.9%), B in 9 cases (42.9%), and C in 3 cases (14.2%). The blood ammonia levels in the rifaximin group improved significantly upon rifaximin therapy, from 124.76±28.68 µg/dL at baseline to 47.00±14.43 µg/dL after 2 weeks (p<0.001) and 49.81±15.02 µg/dL after 24 weeks (p<0.001). The CONUT scores improved significantly during rifaximin therapy, from 6.47±3.25 at baseline to 3.33±2.65 after 24 weeks (p=0.0007). The ALBI scores also improved significantly from -0.39±1.89 at baseline to -2.20±0.55 after 24 weeks (p=0.0002). The SMI scores showed that the body composition had been maintained in response to rifaximin therapy (50.20±7.67 at baseline and 51.29±7.62 after 24 weeks). Conclusion Rifaximin administration for hepatic encephalopathy improved the CONUT and ALBI scores. It may have a secondary effect on the improvement in the nutritional status and hepatic reserve.

A 62-year-old man initially underwent transcatheter arterial chemoembolization for the treatment of hepatocellular carcinoma (HCC). One year after the initial treatment, he developed anemia. Upper gastrointestinal endoscopy revealed irregularly elevated tumors in the lower anterior gastric body, which were diagnosed to be metastasis from HCC. Left gastric artery coil embolization was performed to prevent sustained bleeding, and his anemia partially improved. In addition to direct invasion, hematogenous metastasis to the stomach from HCC is possible and therefore should be considered during treatment. Transcatheter arterial embolization for gastric metastasis is an effective treatment method which achieves a good degree of hemostasis in patients without any surgical indications.

When performing partial splenic arterial embolization (PSE), it can be difficult to determine the embolization ratio based on 2-dimensional digital subtraction angiography (DSA) image diagnosis alone. Therefore, at our department, we conduct computed tomography (CT) imaging intraoperatively and postoperatively to determine whether the planned embolization has been achieved. In recent years, developments in interventional radiology devices have enabled diagnostic imaging using cone beam CT. Here, we investigated whether the embolization ratio could be predicted from volume measurement with cone beam CT in PSE.We investigated correlations between volume measurement with conventional CT angiography (CTA) and volume measurement with cone beam CTA in 11 cases that underwent PSE with cone beam CT guidance (Allura Clarity FD20; Phillips, Amsterdam, The Netherlands) between December 2013 and May 2018.The mean subject age was 65.0 ± 5.8 years (6 men, 5 women). The subjects had underlying liver disorders of hepatitis C virus infection (4 cases), nonalcoholic steatohepatitis (4 cases), and alcohol-related disease (3 cases). A positive correlation was noted between conventional CTA and cone beam CTA, with infarction rates of 61.28â±â9.31% and 64.04â±â9.24%, respectively. The correlation coefficient between the 2 variables was .772.Because blood washout occurs rapidly in the spleen, contrast medium had to be continuously injected during imaging to enable dual-phase imaging with cone beam CT. However, we successfully performed imaging up to the second phase and volume measurement for the embolization ratio by inserting a catheter into the splenic artery and confirming the cone beam CT arrival time from the DSA images. The results were almost identical to those obtained from volume measurement with conventional CT based on CTA imaging. Thus, our results suggest that the splenic embolization ratio measurement obtained via cone beam CTA can be used to assess PSE treatment endpoints.
