A smartphone app-based intervention combined with face-to-face sessions for alcohol dependence at internal medicine clinics: A randomized controlled trial.

BACKGROUND: Addressing the limited access to treatments for alcohol dependence, we developed ALM-002, a therapeutic application to be "prescribed" for non-abstinence-oriented treatment in internal medicine settings. Our objective was to preliminarily assess the efficacy and safety of ALM-002. METHODS: In a multicenter, open-label randomized controlled trial, participants aged ≥20 with alcohol dependence and daily alcohol consumption exceeding 60 g for men and 40 g for women, without severe complications, were randomly assigned to either the intervention group using ALM-002 or the treatment-as-usual control group. Participant in both groups received individual face-to-face sessions by physicians at weeks 0, 4, 8, and 12. The primary endpoint was the change in heavy drinking days (HDDs) from week 0 to week 12. A mixed model for repeated measures was employed. RESULTS: We enrolled 43 participants: 22 in the intervention group and 21 in the control group. A significant reduction in HDDs every 4 weeks from week 0 to week 12 was observed, with a between-group difference of -6.99 days (95% CI: -12.4 to -1.6 days, standardized mean difference: -0.80). CONCLUSIONS: These results indicate the potential of ALM-002 as a viable treatment for alcohol dependence. Further studies are needed to evaluate the clinical potential of ALM-002.

Treatment options for solitary hepatocellular carcinoma ≤5 cm: surgery vs. ablation: a multicenter retrospective study.

BACKGROUND/AIM: The aim of this study was to compare the therapeutic efficacy of ablation and surgery in solitary hepatocellular carcinoma (HCC) measuring ≤5 cm with a large HCC cohort database. METHODS: The study included consecutive 2,067 patients with solitary HCC who were treated with either ablation (n=1,248) or surgery (n=819). Th e patients were divided into three groups based on the tumor size and compared the outcomes of the two therapies using propensity score matching. RESULTS: No significant difference in recurrence-free survival (RFS) or overall survival (OS) was found between surgery and ablation groups for tumors measuring ≤2 cm or >2 cm but ≤3 cm. For tumors measuring >3 cm but ≤5 cm, RFS was significantly better with surgery than with ablation (3.6 and 2.0 years, respectively, P=0.0297). However, no significant difference in OS was found between surgery and ablation in this group (6.7 and 6.0 years, respectively, P=0.668). CONCLUSION: The study suggests that surgery and ablation can be equally used as a treatment for solitary HCC no more than 3 cm in diameter. For HCCs measuring 3-5 cm, the OS was not different between therapies; thus, ablation and less invasive therapy can be considered a treatment option; however, special caution should be taken to prevent recurrence.

Effect of butyrate-producing enterobacteria on advanced hepatocellular carcinoma treatment with atezolizumab and bevacizumab.

AIM: Multiple studies have revealed the correlation between gut microbiome and the response to checkpoint inhibitors (CPIs) in patients with cancer, and oral administration of butyrate-producing enterobacteria has been reported to enhance the efficacy of CPIs. However, the effects of enterobacteria on patients with hepatocellular carcinoma (HCC) are not well understood. METHODS: In this retrospective multicenter study, we enrolled 747 patients with advanced HCC, treated with atezolizumab and bevacizumab combination therapy. Tumor response, survival, and adverse effects were compared between 99 patients who ingested drugs containing butyric acid-producing enterobacteria (butyric acid group) and the remaining patients (control group). RESULTS: Objective response and disease control rates in butyric acid group (29.7% and 77.8%, respectively) were higher than those in the control group (26.4% and 72.7%, respectively). However, the differences were not statistically significant (p = 0.543 and p = 0.222, respectively). No difference in median survival time was observed between the two groups (20.0 months and 21.4 months, respectively; p = 0.789), even after matching the backgrounds of the patients with propensity scores (p = 0.714). No adverse effects occurred upon the administration of butyrate-producing bacteria. However, proteinuria (41.4% vs. 30.9%; p = 0.041), fever (17.2% vs. 10.2%, p = 0.036), and diarrhea (15.2% vs. 6.2%; p = 0.001) occurred more frequently in the butyric acid group. CONCLUSION: Butyrate-producing bacteria does not enhance the efficacy of atezolizumab-bevacizumab combination therapy in patients with HCC.

Predictive Factors for Recovery from Alcoholic Liver Failure.

Alcoholic liver disease is a risk factor for non-virus-related hepatocellular carcinoma (HCC), which is increasing in prevalence. This study aimed to identify the factors for recovery from alcoholic liver failure. Sixty-two consecutive patients hospitalized for alcoholic liver failure at Okayama City Hospital were enrolled. The characteristics of patients who survived to the 1-month follow-up and whose liver function improved to Child-Pugh A at 3 months (CPA3) and 12 months (CPA12) were compared with the rest of the patients. The survivors at 1 month (50 patients) were significantly younger than the deceased patients and had better liver and renal function with higher levels of γ-glutamyl transferase (GGT). The same factors, except renal function, were correlated with achieving CPA3. High AST, ALT, and GGT levels as well as short spleen length, total abstinence, and good Child-Pugh scores at admission were identified as factors for achieving CPA12. The extent of alcohol intake before admission was not identified as a risk factor in any analysis. In conclusion, baseline liver function is crucial for survival and achieving CPA3, whereas high transaminase and γ-GTP levels, the absence of splenomegaly, and total abstinence are significant factors for achieving CPA12.

Chronological change in serum albumin as a prognostic factor in patients with hepatocellular carcinoma treated with lenvatinib: proposal of albumin simplified grading based on the modified albumin-bilirubin score (ALBS grade).

BACKGROUND: The albumin-bilirubin (ALBI) score and the modified ALBI (mALBI) grade are known useful prognostic factors for patients with hepatocellular carcinoma (HCC) treated with lenvatinib (LEN-HCC). However, the ALBI score requires complicated logarithmic calculations. Therefore, we attempted to create a simplified score. METHODS: We developed the albumin simplified (ALBS) grade that corresponded to mALBI using the data of 5985 newly developed HCC and examined the usefulness of this grading system for the prediction of the prognosis of 678 patients with LEN-HCC. RESULTS: The analysis using Cox proportional hazard models revealed that the overall survival of patients with LEN-HCC was not correlated with the total bilirubin but albumin (Alb), which means that the prediction with Alb alone was logical. The ALBS grade cutoffs that corresponded to mALBI grade 1, 2a, 2b, and 3 were Alb ≧ 4.0 g/dL, 4.0 g/dL > Alb ≧3.5 g/dL, 3.5 g/dL > Alb≧2.8 g/dL, and Alb < 2.8 g/dL, respectively. The stratification ability of the ALBS grade for LEN-HCC was good. The Akaike information criterion (AIC) and c-index were comparable with those of mALBI (AIC 4096.3 vs. 4090.7, c-index 0.765 vs. 0.778). The prognosis of LEN-HCC was stratified by the ALBS grade at 1 month after starting LEN, and patients with ALBS grade 1/2a demonstrated better survival than patients with ALBS grade 2b/3 regardless of the ALBS grade before treatment. CONCLUSION: The ALBS grade is easy to calculate and is useful for the prediction of the prognosis of LEN-HCC.

Abnormal fucosylation of alpha-fetoprotein in patients with nonalcoholic steatohepatitis.

AIM: Nonalcoholic steatohepatitis (NASH) is a risk factor for nonvirus-related hepatocellular carcinoma, which is increasing in prevalence. The aim of this study was to clarify the clinical application of fucosylated alpha-fetoprotein (AFP-L3) in the process of nonalcoholic fatty liver (NAFL) disease development. METHODS: Serum samples from 115 diabetes mellitus (DM), 36 NAFL, and 119 NASH patients were analyzed for AFP-L3 expression using raw data of a micro total analysis system. These data were then compared with the clinical characteristics of the patients. A validation study was also undertaken with 55 samples (17 NAFL and 38 NASH). RESULTS: Trace amounts of AFP-L3 were detected in 3.5%, 16.7%, and 58.0% of patients with DM, NAFL, and NASH, respectively. The odds ratio of AFP-L3 positivity for the diagnosis of NASH in multivariate analysis was 9.81 (95% confidence interval, 3.77-25.5). The rates in patients without fibrosis or with stage 1, stage 2, stage 3, and stage 4 fibrosis were 14.7%, 31.3%, 63.0%, 86.2%, and 100%, respectively. The rates were significantly increased according to the advancement of liver fibrosis (p < 0.001); however, no difference in the positive rate of AFP-L3 was observed between patients with and without fatty livers and between patients with normal and abnormal transaminase. The same relationship was also observed in the validation cohort. CONCLUSION: Abnormal fucosylation of AFP occurred in patients with NASH, so it could be useful for the screening of NASH in patients with DM, as well as for the differential diagnosis of NASH and the evaluation of fibrosis.

Early detection of hepatocellular carcinoma in patients with diabetes mellitus.

OBJECTIVES: Diabetes mellitus is a risk factor for non-B, non-C hepatocellular carcinoma (NBNC-HCC); however, the number of diabetes mellitus patients is too large to examine tumor occurrence with periodic imaging modalities. Thus, the aim of this study was to develop a novel strategy for early detection of NBNC-HCC in diabetes mellitus patients. PATIENTS AND METHODS: Ninety-three diabetes mellitus patients who had a single NBNC-HCC tumor less than 2 cm in diameter were selected from 6789 HCC patients. As controls, 172 tumor-free diabetes mellitus patients were enrolled. Characteristics were compared between groups. Furthermore, the efficacy of FIB4A, a new integrated score with FIB4 and alpha-fetoprotein, was analyzed as a marker for the early diagnosis of NBNC-HCC. RESULTS: Age, percentage of males, alcohol consumption, total bilirubin, transaminases, γ-glutamyl transpeptidase, FIB4 index, alpha-fetoprotein, and des-gamma-carboxy-prothrombin were higher in NBNC-HCC patients, whereas albumin and platelet counts were higher in the diabetes mellitus control group. Among these factors, the FIB4 index showed the highest odds ratio [OR: 20.0, 95% confidence interval (CI): 9.60-41.7] followed by alpha-fetoprotein (OR: 12.8, 95% CI: 6.53-25.4). A newly developed score, FIB4A, showed the highest area under the receiver operating characteristic curve (0.959) among the factors examined. The sensitivity was 86.2% at a Youden index cutoff (3.5) and it increased to 95.4%, while keeping high specificity (70.9%) when a cutoff of 2.5 was used. CONCLUSION: FIB4A is a potential marker for early detection of NBNC-HCC in patients with diabetes mellitus. However, further studies are needed to confirm these findings.

Treatment of Intermediate-Stage Hepatocellular Carcinoma in Japan: Position of Curative Therapies.

BACKGROUND: Transcatheter arterial chemoembolization (TACE) is the standard therapy for intermediate-stage (IM) hepatocellular carcinoma (HCC). However, IM-HCC includes various clinical conditions, and various therapies were conducted in practice. In this study, we retrospectively analyzed the actually conducted treatments for IM-HCC and their efficacies to elucidate the treatment strategies suitable for IM-HCC. METHODS: This study included 627 IM-HCC of 5,260 HCC from 9 hospitals. We examined the treatment strategies of these patients and analyzed the efficacy of each therapy with the Cox proportional hazard model and propensity score-matched analysis. RESULTS: Liver resection, radiofrequency ablation (RFA), and TACE were performed in 165, 108, and 351 patients, respectively. Liver resection and RFA were preferably selected in cases of Barcelona Clinic Liver Cancer (BCLC)-B1/B2, and patient survival was significantly longer than in those treated with TACE (p< 0.0001). However, no beneficial effect of these active therapies was observed in cases of BCLC-B3/B4. Multivariate analysis revealed that surgical resection (hazard ratio = 0.384) and RFA (hazard ratio = 0.597) were negative risk factors for survival. Propensity score-matching analysis revealed that -survival of RFA-treated patients was longer than that of TACE-treated patients (p = 0.036). CONCLUSION: RFA and surgical resection were effective for IM-HCC, particularly in BCLC-B1/B2 cases.

EZ-ALBI Score for Predicting Hepatocellular Carcinoma Prognosis.

INTRODUCTION: The ALBI score is acknowledged as the gold standard for the assessment of liver function in patients with hepatocellular carcinoma (HCC). Unlike the Child-Pugh score, the ALBI score uses only objective parameters, albumin (Alb) and total bilirubin (T.Bil), enabling a better evaluation. However, the complex calculation of the ALBI score limits its applicability. Therefore, we developed a simplified ALBI score, based on data from a large-scale HCC database. We used the data of 5,249 naïve HCC cases registered in eight collaborating hospitals. METHODS: We developed a new score, the EZ (Easy)-ALBI score, based on regression coefficients of Alb and T.Bil for survival risk in a multivariate Cox proportional hazard model. We also developed the EZ-ALBI grade and EZ-ALBI-T grade as alternative options for the ALBI grade and ALBI-T grade and evaluated their stratifying ability. RESULTS: The equation used to calculate the EZ-ALBI score was simple {[T.Bil (mg/dL)] - [9 × Alb (g/dL)]}; this value highly correlated with the ALBI score (correlation coefficient, 0.981; p < 0.0001). The correlation was preserved across different Barcelona clinic liver cancer grade scores (regression coefficient, 0.93-0.98) and across different hospitals (regression coefficient, 0.98-0.99), indicating good generalizability. Although a good agreement was observed between ALBI and EZ-ALBI, discrepancies were observed in patients with poor liver function (T.Bil, ≥3 mg/dL; regression coefficient, 0.877). The stratifying ability of EZ-ALBI grade and EZ-ALBI-T grade were good and their Akaike's information criterion values (35,897 and 34,812, respectively) were comparable with those of ALBI grade and ALBI-T grade (35,914 and 34,816, respectively). CONCLUSIONS: The EZ-ALBI score, EZ-ALBI grade, and EZ-ALBI-T grade are useful, simple scores, which might replace the conventional ALBI score in the future.

Utility of FIB4-T as a Prognostic Factor for Hepatocellular Carcinoma.

BACKGROUND: Most integrated scores for predicting the prognosis of patients with hepatocellular carcinoma (HCC) comprise tumor progression factors and liver function variables. The FIB4 index is an indicator of hepatic fibrosis calculated on the basis of age, aspartate aminotransferase (AST) levels, alanine aminotransferase (ALT) levels, and platelet count, but it does not include variables directly related to liver function. We propose a new staging system, referred to as "FIB4-T," comprising the FIB4 index as well as tumor progression factors, and examine its usefulness. METHOD: Subjects included 3800 cases of HCC registered in multiple research centers. We defined grades 1, 2, and 3 as a Fibrosis-4 (FIB4) index of <3.25, 3.26⁻6.70, and >6.70 as FIB4, respectively, and calculated the FIB4-T in the same manner in which the JIS (Japan Integrated Staging Score) scores and albumin-bilirubin tumor node metastasis (ALBI-T) were calculated. We compared the prognostic prediction ability of FIB4-T with that of the JIS score and ALBI-T. RESULTS: Mean observation period was 37 months. The 5-year survival rates (%) of JIS score (0/1/2/3/4/5), ALBI-T (0/1/2/3/4/5) and FIB4-T (0/1/2/3/4/5) were 74/60/36/16/0, 82/66/45/22/5/0 and 88/75/65/58/32/10, respectively. Comparisons of the Akaike information criteria among JIS scores, ALBI-T, and FIB4-T indicated that stratification using the FIB4-T system was comparable to those using ALBI-T and JIS score. The risk of mortality significantly increased (1.3⁻2.8 times/step) with an increase in FIB4-T, and clear stratification was possible regardless of the treatment. CONCLUSION: FIB4-T is useful in predicting the prognosis of patients with HCC from a new perspective.

Application of radiofrequency ablation for the treatment of intermediate-stage hepatocellular carcinoma.

BACKGROUND AND AIM: Transcatheter arterial chemoembolization (TACE) is a standard therapy for the treatment of intermediate-stage hepatocellular carcinoma (HCC). In this study, we tried to elucidate the possibility of using radiofrequency ablation (RFA) as an alternative treatment of intermediate-stage HCC. METHODS: Among 246 patients who were initially diagnosed with intermediate-stage HCC, 76 who were treated with TACE (TACE group) and 91 who were treated with RFA (RFA group) were enrolled in this study. The risk for survival was analyzed with the Cox Proportional Hazard Model, and the survival rates were compared using propensity score matching. RESULTS: About half (50.6%) of the intermediate-stage HCC patients in the RFA group were diagnosed with Barcelona Clinic Liver Cancer substage-B1 (BCLC-B1) compared with only 19.7% of the patients in the TACE group. Survival of the RFA group was longer than that of TACE group in patients with BCLC-B1 and BCLC-B2. In contrast, no difference between groups was observed in patients with BCLC-B3/4. Multivariate analysis revealed that large tumor size (>30 mm, hazard ratio = 1.685, P = 0.043), high des-γ-carboxyprothrombin (>100 mAU/mL, hazard ratio = 1.920, P = 0.012), and TACE group (hazard ratio = 1.896, P = 0.016) were significant risk factors for survival. Overall 3-year survival of the patients in the RFA group (69.5%) was significantly longer than that of patients in the TACE group (51.5%) after propensity score matching (P = 0.032). No significant adverse events were observed in either group. CONCLUSIONS: RFA was useful for the treatment of less advanced intermediate-stage HCC and could be an alternative to TACE in selected cases.

Modified radiofrequency ablation for the treatment of hepatocellular carcinoma.

AIM: Radiofrequency ablation is commonly used for the treatment of early hepatocellular carcinoma. However, it requires time to ablate sufficient areas, resulting in increased burden for the patients and operators. We introduce a novel and simple method to overcome this problem. METHODS: We placed the grounding pad on the back (Back group) instead of the thigh of the patient (Thigh group). To assess the effect of this method, we randomly assigned the patients into two groups, based on the location of the grounding pad, and compared the outcomes. RESULTS: The ablation time until two roll-offs was shorter in the Back group than in the Thigh group (median, 2.5 min vs 3.4 min; P = 0.01). The ablated area was larger in the Back group than that in the Thigh group (P = 0.01) and pain was less in the Back group (P = 0.02). No severe side-effects were observed in either group. CONCLUSION: This new method is useful in that it achieved shorter ablation times, expansion of the ablated areas, and reduction of pain during the ablation.

Percutaneous Radiofrequency Ablation for Intermediate-Stage Hepatocellular Carcinoma.

OBJECTIVES: Radiofrequency ablation plays a key role in the treatment of early-stage hepatocellular carcinoma. However, it is not recommended for intermediate-stage hepatocellular carcinoma. The objective of this study was to clarify the efficacy and safety of radiofrequency ablation for treating intermediate-stage hepatocellular carcinoma. METHODS: We examined the outcome of 65 consecutive patients who were treated with radiofrequency ablation with or without transarterial chemoembolization for intermediate-stage hepatocellular carcinoma. RESULTS: With a median follow-up of 37 months, overall survival rates of 65 cases at 1, 3, 5, and 7 years were 90, 70, 51, and 36%, respectively. Multivariate analysis of clinical parameters revealed that the multicentric occurrence (MC)/intrahepatic metastasis (IM) was the only significant prognostic factor for overall survival (hazard ratio, 4.9; 95% confidence intervals, 2.1-11.4). Tumor size and tumor number were not significant factors for survival. The overall survival rates of patients with MC (n = 33) at 1, 3, 5, and 7 years were 97, 90, 80, and 59%, respectively; those for patients with IM (n = 32) were 86, 55, 14, and 8%, respectively (p < 0.0001). Two cases (4.9%) had complications of hemothorax and diaphragmatic burn; however, no major complications were observed. CONCLUSION: Radiofrequency ablation is safe and effective for the treatment of intermediate-stage hepatocellular carcinoma, especially for patients with MC.

Liver Sarcoidosis with Unique MRI Images Using Gadolinium Ethoxybenzyl Diethylenetriamine Pentaacetic Acid.

Sarcoidosis is a systemic disease characterized by the formation of non-caseating granulomas in multiple organs. In the diagnosis of sarcoidosis, imaging modalities such as ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) are useful;however, there are few reports of MRI imaging using gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB) MRI. A 46-year-old Japanese female with suspected pulmonary sarcoidosis was admitted to our hospital because low-density mottles in the liver were observed incidentally by chest CT. The low-density mottles were not enhanced at the arterial phase or portal phase by abdominal CT and MRI, and decreased uptake was observed in the hepatobiliary phase of Gd-EOB MRI. No hematological disorder was observed except for a slight increase of biliary enzymes. The lesion was diagnosed as liver sarcoidosis by the liver biopsy. Since the patient refused steroid therapy, we prescribed ursodeoxycholic acid (UDCA). 600mg/day. The serum levels of biliary enzymes were normalized and the abdominal CT findings gradually improved after the initiation of UDCA medication. Gd-EOB MRI showed unique hypointense areas in the liver at the hepatobiliary phase, which might be useful in the diagnosis of liver sarcoidosis.

Safety and efficacy of radiofrequency ablation with artificial ascites for hepatocellular carcinoma.

The artificial ascites technique is often used during radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) treatment because it prevents visceral damage and improves visualization by minimizing interference of the lungs and mesentery. This study determined the efficacy and safety of RFA using the artificial ascites technique in HCC patients. We examined 188 HCC patients who were treated by RFA and fulfilled the Milan criteria. Treatment outcomes (complete ablation rate, local recurrence rate, complication rate, liver function including total bilirubin level, alanine aminotransferase level, albumin level, and prothrombin time) were compared among patients divided into 3 groups based on the volume of artificial ascites injected:Group I (n = 86), no artificial ascites injected;Group II (n = 35), < 1,000 ml artificial ascites injected;and Group III (n = 67), > 1,000 ml artificial ascites injected. No significant difference was observed in complete ablation or local recurrence rates among the 3 groups, or in the extent of liver function damage after RFA. Artificial ascites disappeared within 7 days; additional diuretics were needed only in 5 (all from Group III) of 102 patients. No serious complications such as intestinal perforation or intraperitoneal bleeding were observed. Thus, we found that artificial ascites injection during RFA is effective and safe, and can be used to prevent major procedural complications.

Radiofrequency ablation for the treatment of hepatocellular carcinoma with decompensated cirrhosis.

BACKGROUND: Radiofrequency ablation (RFA) is used to treat early-stage hepatocellular carcinoma (HCC), but is sometimes avoided in patients with decompensated liver cirrhosis because of the possible side effect of deterioration of liver function. AIMS: In this study, we report the safety and effects of RFA for treating HCC patients with Child-Pugh B/C liver cirrhosis. METHODS: Sixty-six consecutive HCC patients with Child-Pugh B/C cirrhosis, who were treated by RFA, were enrolled in this study. We analyzed patient outcomes, the complications of RFA, and changes in liver function and tumor markers. RESULTS: Fifty-six patients were classified as Child-Pugh class B, and 10 were classified as class C. The overall survival rates in patients with Child-Pugh B and C cirrhosis were 82 and 83% at 1 year and 47 and 31% at 3 years, respectively. Serum total bilirubin (T.Bil), albumin, prothrombin time, ascites, and encephalopathy were unchanged at 1, 3, and 6 months after RFA in patients with Child-Pugh B cirrhosis; however, serum T.Bil levels increased significantly at 6 months after RFA in 6/10 (60%) patients with Child-Pugh C cirrhosis. Hemothorax and rupture of esophageal varices were observed in 2 patients; however, there were no complications related to poor liver function. CONCLUSION: RFA is a useful modality for treating HCC in patients with poor liver function such as Child-Pugh B and C, but careful monitoring after RFA must be needed.

Percutaneous radiofrequency ablation for treatment of hepatocellular carcinoma in the caudate lobe.

OBJECTIVE: This study aimed to evaluate the efficacy and safety of percutaneous radiofrequency ablation (RFA) for the treatment of hepatocellular carcinoma (HCC) in the caudate lobe, where RFA is considered to be difficult. MATERIALS AND METHODS: Of a total of 810 patients treated by ultrasound-guided radiotherapy between July 2002 and May 2010, medical records of 50 consecutive patients with HCC in the caudate lobe were reviewed in this retrospective study. Twenty-two tumors were found to be in the paracaval portion and 28 in the Spiegel lobe. We retrospectively reviewed the procedures, treatment effect, and complications. RESULTS: For all paracaval tumors and eight Spiegel lobe tumors, we used the intercostal approach, and for the remaining Spiegel tumors (n = 20) we used the pass-the-left approach. We found that all tumors were successfully treated, and the local recurrence rate after 2 years was 12%. Cases of mortality or major complications after RFA were absent. CONCLUSION: RFA appears to be an effective treatment modality for HCC in the caudate lobe.

[Case with hepatic artery aneurysm discovered after suffering from infectious endocarditis].

A 53-year-old man suffering from infectious endocarditis developed a rupture of the mitral valve tendinous cord. Consequently a mitral valvoplasty was performed. Forty days later, the patient presented with sudden and severe epigastralgia and hematemesis, and was rushed to our hospital. An arterial phase of an abdominal contrast-enhanced CT showed a mass 3 cm in diameter which was strongly enhanced along the side of the hepatic portal region and therefore it was thought to be an aneurysm. An abdominal angiography revealed an aneurysm of the right hepatic artery. As a result, an embolization with coils was performed. Nine months after treatment, CT examination of the abdomen revealed that the aneurysm had completely disappeared.

Gastrobiliary motility is not coordinated in patients with non-ulcer dyspepsia of normal gastric emptying time: simultaneous sonographic study.

BACKGROUND: Disorders of the motor function of the upper gastrointestinal tract have been implicated in the pathogenesis of non-ulcer dyspepsia. Approximately 50% of patients with abdominal symptoms (without ulcer) have normal gastric emptying. Apart from gastric emptying, other mechanisms are very important in the etiology of non-ulcer dyspepsia. METHODS: Gastric emptying and gallbladder motility were simultaneously investigated in 16 patients with non-ulcer dyspepsia and in 15 healthy controls. Fasting blood samples were taken, and pepsinogen levels were assayed. RESULTS: Gastric emptying time, fasting antral diameter, and post-prandial antral diameter were not significantly different between the patients with non-ulcer dyspepsia and the controls. Fasting gallbladder volume, the time required to reach minimal gallbladder residual volume, minimal gallbladder residual volume, and the serum levels of pepsinogen were not significantly different. Simple linear regression was used to summarize the relationship between gastric emptying time and time required to reach minimal gallbladder residual volume. In the controls, the gastric emptying time and time required to reach minimal gallbladder residual volume were linearly related. However, in the patients with non-ulcer dyspepsia, they were not related. CONCLUSIONS: These observations suggest that disturbance of coordination between gastric emptying and gallbladder emptying is a cause of the symptoms of non-ulcer dyspepsia.
