Effectiveness of 1-year pemafibrate treatment on steatotic liver disease: the influence of alcohol consumption.

BACKGROUND/AIMS: Pemafibrate is a selective peroxisome proliferator-activated receptor α modulator that improves serum alanine aminotransferase (ALT) in dyslipidemia patients. We previously reported that pemafibrate significantly improves liver function, serum triglyceride (TG) levels and liver stiffness in non-alcoholic fatty liver disease patients, however the influence of alcohol consumption was not considered. Therefore, we explored pemafibrate efficacy in patients with steatotic liver disease (SLD) and alcohol-associated liver disease (ALD). METHODS: We retrospectively evaluated pemafibrate efficacy on liver enzymes and lipids in metabolic dysfunction-associated SLD (MASLD) (n = 93), MASLD plus increased alcohol intake (MetALD; n = 23) and ALD (n = 22) patients who had taken pemafibrate for at least 48 weeks. Liver shear wave velocity (SWV, n = 75) was also evaluated. RESULTS: In MASLD group, ALT, aspartate aminotransferase (AST), γ-glutamyl transpeptidase (γ-GTP) and TG values were significantly decreased from baseline to week 24 and week 48 ( P  < 0.0001). ALT and TG values in MetALD group and ALT and AST values in ALD group were also significantly decreased from baseline to week 24 and week 48. Study participant SWV values decreased from baseline to week 48. We observed no significant difference in changes to ALT, AST, γ-GTP and TG (value at week 24 or week 48 minus value at baseline) among the three groups. CONCLUSION: Pemafibrate improves liver function and liver stiffness thus making it a promising therapeutic agent for SLD, even in patients with excess alcohol consumption (MetALD and ALD groups).

Serum Zinc-α2-glycoprotein Levels Are Associated with the Hepatorenal Function and Predict the Survival in Cases of Chronic Liver Disease.

Objective Zinc-α2-glycoprotein (ZAG) is secreted by various organs, such as liver, kidney and adipose tissue, is involved in lipolysis, and may contribute to the pathogenesis of chronic liver disease (CLD). We therefore assessed whether or not ZAG is a surrogate marker for the hepatorenal function, body composition and all causes of mortality, as well as complications, including ascites, hepatic encephalopathy (HE) and portosystemic shunts (PSS) in CLD. Methods Serum ZAG levels were measured in 180 CLD patients upon hospital admission. The associations of ZAG levels with the liver functional reserve and clinical parameters were investigated using a multiple regression analysis. Kaplan-Meier analyses were performed to evaluate the associations of the ZAG/creatinine ratio (ZAG/Cr) and prognostic factors with mortality. Results High serum ZAG levels were associated with preserving the liver function and renal insufficiency. A multiple regression analysis showed that the estimated glomerular filtration rate (p<0.0001), albumin-bilirubin (ALBI) score (p=0.0018) and subcutaneous fat area (p=0.0023) had a significant independent correlation with serum ZAG levels. Serum ZAG levels were elevated in the absence of HE (p=0.0023) and PSS (p=0.0003). In all patients and those without hepatocellular carcinoma (HCC), the cumulative mortality rate was significantly decreased in patients with a high ZAG/Cr compared with those with a low ZAG/Cr (p=0.0018 and p=0.0002, respectively). The ZAG/Cr, presence of HCC, ALBI score and psoas muscle index were independent predictors of the prognosis in CLD patients. Conclusion Serum ZAG levels are associated with the hepatorenal function and can be used to predict the survival in CLD patients.

Hepatocellular Carcinoma Pseudoprogression Involving the Main Portal Vein, Right Ventricular Invasion, and Exacerbation of Lung Metastases in a Patient on Atezolizumab Plus Bevacizumab.

A 70-year-old man was diagnosed with hepatocellular carcinoma (HCC) with portal vein invasion and lung metastases, for which atezolizumab plus bevacizumab (ATZ/BEV) was initiated. After two months, computed tomography revealed tumor growth accompanied by ascites, right ventricular invasion, exacerbation of the lung metastases, and main portal vein invasion. However, continuation of ATZ/BEV caused remarkable size reductions in all lesions, finally resulting in the disappearance of the vascular invasion and lung metastases after nine cycles of treatment. The tumor growth was considered to reflect pseudoprogression, which is difficult to distinguish from hyperprogression. We herein report a remarkable HCC case of pseudoprogression on ATZ/BEV.

The prognostic role of controlling nutritional status and skeletal muscle mass in patients with hepatocellular carcinoma after curative treatment.

BACKGROUND: Nutritional status and skeletal muscle mass affect the prognosis of hepatocellular carcinoma (HCC). Nutritional status is closely associated with skeletal muscle mass. Here, we investigate the effect of controlling preoperative nutritional status and skeletal muscle mass on the prognosis of HCC after curative treatment. METHODS: This retrospective analysis contained 181 patients who received curative treatment of HCC including liver resection or radiofrequency ablation (RFA) therapy. Nutritional status and skeletal muscle mass were evaluated prior to therapy using the controlling nutritional status (CONUT) score and psoas muscle mass index (PMI), respectively. Associations of predictor variables with overall survival (OS) and progression-free survival (PFS) were determined using Cox proportional hazards regression and CHAID decision tree algorithm analysis. RESULTS: A total of 111 patients (61.3%) were determined to be of poor nutritional status and 100 patients (55.2%) had muscle mass depletion. Patients with PS 0, Barcelona clinic liver cancer (BCLC) stage 0, low CONUT score, and high PMI showed significantly better OS than those with PS 1, BCLC stage A, high CONUT score, and low PMI. Multivariate analysis indicated that a high CONUT score [hazard ratio (HR) 4.130; 95% confidence interval (CI), 1.713-9.958; P < 0.01) and low PMI (HR 4.625; 95% CI, 1.704-12.549; P < 0.01) found to be useful for predicting OS in patients after curative treatment of HCC. Regarding PFS, a significant predictor was only tumor numbers in univariate analysis (HR 2.147; 95% CI, 1.350-3.414; P = 0.001). In decision tree analysis, the mortality rate was 28.8%, 12.5%, and 1.9% in patients with a high CONUT score, with a low CONUT score-low PMI, or with a low CONUT score-high PMI, respectively. CONCLUSION: The combined CONUT score and PMI were found to be independent predictors of OS in HCC patients after liver resection or RFA.

Association of lithocholic acid with skeletal muscle hypertrophy through TGR5-IGF-1 and skeletal muscle mass in cultured mouse myotubes, chronic liver disease rats and humans.

Background: Hepatic sarcopenia is one of many complications associated with chronic liver disease (CLD) and has a high mortality rate; however, the liver-muscle axis is not fully understood. Therefore, few effective treatments exist for hepatic sarcopenia, the best of which being branched-chain amino acid (BCAA) supplementation to help increase muscle mass. Our aim was to investigate the molecular mechanism(s) of hepatic sarcopenia focused on bile acid (BA) composition. Methods: The correlation between serum BA levels and psoas muscle mass index (PMI) was examined in 73 CLD patients. Gastrocnemius muscle phenotype and serum BA levels were assessed in CLD rats treated with BCAA. Mouse skeletal muscle cells (C2C12) were incubated with lithocholic acid (LCA), G-protein-coupled receptor 5 (TGR5) agonist or TGR5 antagonist to assess skeletal muscle hypertrophy. Results: In human CLD, serum LCA levels were the sole factor positively correlated with PMI and were significantly decreased in both the low muscle mass group and the deceased group. Serum LCA levels were also shown to predict patient survival. Gastrocnemius muscle weight significantly increased in CLD rats treated with BCAA via suppression of protein degradation pathways, coupled with a significant increase in serum LCA levels. LCA treated C2C12 hypertrophy occurred in a concentration-dependent manner linked with TGR5-Akt pathways based upon inhibition results via a TGR5 antagonist. Conclusions: Our results indicate LCA-mediated skeletal muscle hypertrophy via activation of TGR5-IGF1-Akt signaling pathways. In addition, serum LCA levels were associated with skeletal muscle mass in cirrhotic rats, as well as CLD patients, and predicted overall patient survival.

The prognostic potential of fragmented CK18 serum levels in HCC patients reflecting disease progression and overall hepatocyte damage.

Background: Fragmented cytokeratin 18 (fCK18) is released from damaged hepatocytes undergoing apoptosis and is recognized as a liver condition biomarker. We have developed a highly sensitive serum fCK18 CLEIA and reported that serum levels of this caspase-derived protein were significantly associated with hepatocyte ballooning, thus assisting in the accurate diagnosis of nonalcoholic steatohepatitis (NASH). We aim to investigate serum fCK18 levels in a variety of chronic liver diseases and to explore its potential as a prognostic marker of survival in hepatocellular carcinoma (HCC) patients. Methods: Serum fCK18 levels were measured using a highly sensitive CLEIA in 497 chronic liver disease patients (297 outpatients and 200 hospitalized with HCC). Results: In 497 chronic liver disease patients, serum fCK18 levels were significantly correlated with overall liver condition, including ALT, FIB-4 index and albumin-bilirubin (ALBI) score and were significantly increased in patients with HCC. In 200 HCC patients, serum fCK18 levels were significantly correlated with alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP), and were significantly associated with HCC stage, whereas FIB-4 index and ALBI score were not changed based on HCC stage. The Survival group had significantly lower levels of serum fCK18, AFP, DCP, FIB-4 index and ALBI score. A ROC analysis yield area under the curve (AUC) value of 0.728 for serum fCK18 is a significantly high value when compared to AUC measurements for other factors. Notably, AUROC values for serum fCK18 levels were constant in the short- and long-term by time-dependent ROC analysis for the prediction of HCC patient survival. HCC patients with serum fCK18 measured at < 1.15 ng/mL, AFP < 7.7 ng/mL, DCP < 133 mAU/mL, ALBI score < -2.97 or FIB-4 index < 6.4 had significantly longer rates of survival when compared to patients with values exceeding these thresholds. Serum fCK18 (HR, 3.5; P < 0.0001), DCP (HR, 3.2; P < 0.0001) and Barcelona Clinic Liver Cancer (BCLC) (HR, 2.4; P = 0.001) values were independent predictors of patient survival. [Conclusion] Serum fCK18 levels reflect overall liver function, the level of liver fibrosis and the progression of HCC, and are a potential predictor of survival in HCC patients.

Recurrent hepatocellular carcinoma with osteoclast-like giant cells: a case report.

BACKGROUND: Hepatocellular carcinoma with osteoclast-like giant cells is very rare and has an extremely poor prognosis. Here, we report a case of hepatocellular carcinoma with osteoclast-like giant cells that had a relatively better prognosis. CASE PRESENTATION: A 70-year-old Japanese man with hepatitis B virus-related liver cirrhosis was admitted to our hospital for the treatment of recurrent hepatocellular carcinoma. At the age of 60 years, he was first diagnosed as having hepatocellular carcinoma in the right lobe (9 cm in diameter), and liver resection of segment 7/8 was performed. Histological findings showed well-differentiated hepatocellular carcinoma. Since then, imaging studies have been performed every 3 or 4 months. One year later, hepatocellular carcinoma recurred in the lateral segment, and radiofrequency ablation was performed. Nine years after the first presentation, hepatocellular carcinoma recurrences were detected in the caudate lobe and segment 5 by imaging studies. Surgical resection of the caudate lobe was performed, and ultrasonography-guided radiofrequency ablation was subsequently performed for the segment 5 tumor. The resected tumor was simple nodular, well-differentiated HCC; it measured 21 × 21 mm and contained many osteoclast-like giant cells. As neither vascular nor bile duct invasion was found, we believe that radical resection was achieved. Since then, the hepatocellular carcinoma has not recurred for over a year and a half. CONCLUSION: Hepatocellular carcinoma with osteoclast-like giant cells is very rare and the prognosis is extremely poor, but early detection can lead to a better clinical course.

Prediction of esophagogastric varices associated with oxaliplatin administration.

BACKGROUND: Oxaliplatin is a key drug for the chemotherapy of colorectal cancer; however, it is also known to cause non-cirrhotic portal hypertension. We aimed to identify the characteristics of patients who developed esophagogastric varices (EGVs) after treatment with oxaliplatin. METHODS: This study retrospectively analyzed patients with colorectal cancer who were treated with chemotherapy including oxaliplatin between 2010 and 2016. All patients were evaluated by contrast-enhanced computed tomography (CE-CT) every 3 months both during and after treatment; and endoscopy was performed when appearance of portal hypertension was suspected. RESULTS: A total of 106 patients were divided into two groups: EGV formation (n = 6) and EGV non-formation (n = 100). In the EGV group, platelet counts decreased and the size of the spleen calculated by CT (CT spleen index; CT-SI) increased markedly. The highest area under the receiver operating characteristic curve (AUC) for the change in platelet counts was 0.81 (80% sensitivity and 83% specificity) at 3 months post treatment, and the maximum AUC for CT-SI was 0.89 (79% sensitivity and 83% specificity) at 6 months post treatment. CONCLUSIONS: EGV formation could be predicted by the assessment of platelet counts and spleen size. If progressive splenomegaly and thrombocytopenia are observed not only during but also after completion of the oxaliplatin-containing chemotherapy, EGVs should be confirmed by endoscopy for avoiding subsequent rupture.

Serum Copeptin and Zinc-α2-glycoprotein Levels Are Novel Biomarkers of Tolvaptan Treatment in Decompensated Cirrhotic Patients with Ascites.

Objective The efficacy of tolvaptan, an orally active vasopressin V2-receptor antagonist, has recently been reported in patients with massive ascites unresponsive to conventional diuretics. However, the effect of tolvaptan varies among patients. Recently, the prognostic role of the tolvaptan response in cases of decompensated liver cirrhosis (LC) has been attracting increasing attention. Using serum copeptin (vasopressin precursor), zinc-α2-glycoprotein (ZAG), cystatin C (renal biomarker), neutrophil gelatinase-associated lipocalin (NGAL) and liver-type fatty acid-binding protein (L-FABP), we explored which factors portend a good response to tolvaptan in LC patients with ascites. Methods We enrolled 113 LC patients and divided them into the tolvaptan treatment group and non-treatment group. Tolvaptan (3.75 or 7.5 mg/day) was administrated to 38 LC patients with ascites, and a follow-up assessment was performed after a 7-day tolvaptan treatment regimen. Results We determined the predictive ability for kidney and/or liver damage of serum copeptin, ZAG, cystatin C, NGAL and L-FABP levels in all patients. After 7-day tolvaptan treatment, 19 patients had lost more than 1.5 kg of body weight (Responders), while 19 showed no marked change in their body weight (Non-responders). Basal blood urea nitrogen (BUN) (p=0.0014), serum copeptin (p=0.0265) and serum ZAG levels (p=0.0142) were significantly higher in the Non-responders than in the Responders. BUN (odds ratio 7.43, p=0.0306), copeptin (odds ratio 9.12, p=0.0136) and ZAG (odds ratio 7.43, p=0.0306) were determined to be predictive factors of drug responsiveness using a multivariate logistic regression analysis. Conclusion Serum BUN, copeptin and ZAG levels predict the patient response to tolvaptan, even when measured prior to treatment.

Serum copeptin level is a biomarker associated with ascites retention and the formation of a portosystemic shunt in chronic liver disease.

BACKGROUND AND AIM: Copeptin is a stable cleavage product of the arginine vasopressin precursor and is equimolarly secreted with arginine vasopressin. We aimed to assess whether copeptin is the surrogate marker for complications related chronic liver disease (CLD) such as ascites, hepatic encephalopathy (HE), portosystemic shunts (PSSs), and all causes of mortality in CLD. METHODS: Serum copeptin was measured in 170 CLD patients upon hospital admission. The association of copeptin levels with liver enzymes, liver functional reserve, and clinical parameters was investigated. Cox proportional hazard regression, logistic regression, and Kaplan-Meier analyses were performed to evaluate the associations of copeptin and ascites, HE and PSS formation, and prognostic factors with short-term (1 year) and long-term (4 years) mortality. RESULTS: Serum copeptin levels were significantly correlated with liver and renal function, elevated in parallel with liver disease progression, and also associated with HE. Serum copeptin, albumin-bilirubin score and hepatocellular carcinoma were independent predictors of PSS formation and decreased rate of survival. Serum copeptin and albumin-bilirubin scores were independent predictors of ascites retention. The short-term and long-term cumulative mortality rate was significantly decreased in patients with serum copeptin >5.5 or >4.8 pmol/mL compared with patients in whom serum copeptin levels were <5.5 or <4.8 pmol/mL (P < 0.0001; P < 0.0001). CONCLUSIONS: Serum copeptin level is a predictor for ascites retention and HE and PSS formation associated with portal hypertension. Moreover, serum copeptin level may be useful in predicting the rate of survival in patients with CLD.

Serum copper, zinc and metallothionein serve as potential biomarkers for hepatocellular carcinoma.

BACKGROUND: Copper (Cu) and zinc (Zn) are essential nutrients and cofactors of enzymatic reactions with their binding partner. Metallothionein (MT) plays an important role in protecting against heavy metals and oxidative injury, however it may also portend drug resistance and a worse prognosis for hepatocellular carcinoma (HCC) patients. The aim of this study was to determine the amount of Cu, Zn, Cu/Zn and MT in evaluating a group of patients with HCC, including those treated with lenvatinib. METHODS: We enrolled 175 patients with HCC (139 men, 36 women; mean age 71.1 years; hepatitis C virus n = 85, hepatitis B virus n = 19, hepatitis C virus and hepatitis B virus n = 2, non-alcoholic steatohepatitis n = 39, alcohol n = 25, others n = 5; Child-Pugh A n = 141, Child-Pugh B n = 30, Child-Pugh C n = 4; Barcelona clinic liver cancer (BCLC) stage 0 n = 38, stage A n = 56, stage B n = 39, stage C n = 38, stage D n = 4). We evaluated the associations between Cu, Zn and MT. The study outcome was liver cancer-specific survival. Moreover, we treated 12 HCC patients with lenvatinib and investigated the changes in MT during lenvatinib therapy. RESULTS: The serum level of Cu was positively correlated with alanine aminotransferase and the BCLC stage. The serum level of Zn decreased concordant with liver disease progression. Patients with a Cu/Zn ratio≥0.999 had significantly improved rates of survival when compared to patients with a Cu/Zn ratio<0.999 (45.3 vs. 30.1 months, p<0.001). MT was significantly correlated with the Cu/Zn ratio and increased after the administration of lenvatinib. Using multivariate Cox regression analyses, it was determined that the Cu/Zn ratio (hazard ratio [HR]: 1.442, p = 0.008), alpha-fetoprotein (HR: 1.000, p<0.001) and BCLC stage (HR: 2.087, p<0.001) were independent predictors of survival. CONCLUSIONS: The Cu/Zn ratio could serve as a useful predictive marker for survival in cases of HCC. MT levels increased in HCC patients receiving lenvatinib therapy, and maybe a predictor of reduced survival.

Hypozincemia is associated with human hepatocarcinogenesis in hepatitis C virus-related liver cirrhosis.

AIM: Hypozincemia is associated with the progression of chronic liver diseases, but it is unknown whether hypozincemia promotes human hepatocarcinogenesis. Our aim is to evaluate the serum zinc levels in liver cirrhosis (LC) patients and clarify the relationship between the serum zinc levels and the development of hepatocellular carcinoma (HCC). METHODS: Cirrhotic patients without HCC (n = 299) were enrolled from 14 medical institutes in Japan as a multicenter prospective study (No. 2028). Of the 299 patients, 157 were included in the present study based on reliable and consistent serum zinc levels and no history of oral zinc supplementation. Clinical parameters associated with the development of HCC were determined. Furthermore, the cumulative incidence of HCC was analyzed using Kaplan-Meier methods and was calculated using the log-rank test. A Cox regression analysis was utilized for the multivariate analysis to evaluate the predictors of hepatocarcinogenesis. RESULTS: Thirty of 157 patients (19.1%) developed HCC during an observation period of 3 years. Serum zinc levels were significantly decreased in hepatitis C virus-related LC (C-LC) patients with HCC (0.0180). The risk factors for incidence of HCC were hypozincemia (0.0014), high α-fetoprotein (0.0080), low branched chain amino acids-to-tyrosine ratio (0.0128), or female sex (0.0228). Hypozincemia (hazard ratio 1.61, 0.0324) was the only significant predictor of hepatocarcinogenesis by multivariate Cox regression analysis. CONCLUSIONS: Hypozincemia is associated with hepatocarcinogenesis in C-LC patients.

Esophagogastric varices were diagnosed in a non-cirrhotic liver case during long-term follow-up after oxaliplatin-based chemotherapy.

Oxaliplatin, a chemotherapeutic agent for colorectal cancer, has been associated with pathological evidence of sinusoidal endothelial injury in the liver. However, esophagogastric varices are a poorly recognized outcome of oxaliplatin-based chemotherapy. We report a 78-year-old man, whose past history of colon cancer was resection and treatment with mFOLFOX6 for 20 weeks, as adjuvant chemotherapy. After 3.5-year follow-up of the oxaliplatin-based chemotherapy, he was diagnosed with esophageal varices without liver dysfunction, indicating that the hepatotoxicity caused by oxaliplatin could be prolonged after its administration. Patients who have received oxaliplatin-based chemotherapy should be followed up carefully over the long term.

Fusobacterium nucleatum detected simultaneously in a pyogenic liver abscess and advanced sigmoid colon cancer.

Fusobacterium nucleatum is an invasive, adherent, and pro-inflammatory anaerobic bacterium involved in various infections and colorectal cancer. We report a case with pyogenic liver abscess, diagnosed with advanced sigmoid colon cancer, in whom F. nucleatum was simultaneously detected. In this patient, F. nucleatum was systematically analyzed using the molecular biological techniques of metagenome analysis, conventional PCR, and microbial fluorescence in situ hybridization.

Curative Effects for B-Cell Lymphoma Accomplished by Direct-Acting Antiviral Agents of Hepatitis C.

Hepatitis C virus (HCV) is a hepatotropic and lymphotropic virus with the capabilities of tumorigenesis. We present an HCV-infected patient affected with B-cell lymphomas after suffering from hepatocellular carcinoma. The patient exhibited curative effects for lymphomas after treatment with sofosbuvir and ledipasvir, which is shown clearly with a positron emission tomography scanner.

Hemoglobin Decrease with Iron Deficiency Induced by Daclatasvir plus Asunaprevir Combination Therapy for Chronic Hepatitis C Virus Genotype 1b.

BACKGROUND: Decreased hemoglobin (Hb) level has been supposed to be a relatively rare side effect of a combination therapy against hepatitis C virus that consists of the NS5A inhibitor daclatasvir (DCV) and the NS3/4A protease inhibitor asunaprevir (ASV). METHODS: The study was conducted in 75 patients with genotype 1b chronic hepatitis C virus infection who had started combination therapy with DCV and ASV at St. Marianna University School of Medicine Hospital between September 2014 and December 2014. RESULTS: Among the patients examined, decreased Hb level by ≥1.5 g/dL from the values at treatment initiation was observed in 11 individuals. This was accompanied by decreased mean corpuscular volume, and iron and ferritin levels. CONCLUSIONS: These findings suggest that the mechanism of the phenomenon is caused by iron deficiency. The underlying mechanism and clinical impacts will need to be further examined.

[Detection of early gastric cancer facilitated by surveillance for a pyogenic liver abscess caused by Streptococcus intermedius].

We report a case of early gastric cancer that was detected during surveillance of a pyogenic liver abscess caused by Streptococcus intermedius, an oral microbiota. Treatment with proton pump inhibitors can result in the alteration of gastric bacterial flora by altering intragastric acidity. This can place immunocompromised patients, such as those with diabetes mellitus and the elderly, at an increased risk for disease of the upper gastrointestinal tract to be a route of bacterial transmission. In this case, the patient developed a pyogenic liver abscess.

Two cases of rupture of esophagogastric varices during the course of oxaliplatin-based chemotherapy for colorectal cancer.

Some cases of portal hypertension developing during the course of oxaliplatin-based chemotherapy have been reported. However, there have been no reports of rupture of esophagogastric varices (EGV) in Japan. We present two cases of rupture of EGV during the course of oxaliplatin-based chemotherapy. One case was treated via balloon-occluded retrograde transvenous obliteration, and the other case was treated by using endoscopic variceal ligation and endoscopic injection sclerotherapy. On the basis of our results, we recommend careful monitoring for the occurrence of EGV during the course of oxaliplatin-based chemotherapy.

Cirrhosis improvement to alcoholic liver fibrosis after passive abstinence.

We present a rare case of long-term alcoholic liver disease that progressed from alcoholic liver fibrosis to alcoholic liver cirrhosis, and following passive abstinence, the patient's condition then improved to alcoholic liver fibrosis. A 70-year-old Japanese man who had consumed large amounts of alcohol since he was 20 years old received a liver biopsy for evaluation of liver dysfunction at the age of 48 in 1991. The biopsy indicated alcoholic liver fibrosis, stage 2. Eight years later, a second biopsy indicated alcoholic liver cirrhosis. The patient continued to drink until a cerebral haemorrhage in 2000 led to left hemiparesis. Thereafter, he had to accept passive abstinence. He then received follow-up liver biopsies in 2001 and 2002, both of which indicated improvement of the fibrosis.

A novel endoscopic papillectomy after a pancreatic stent placement above the pancreatic duct orifice: inside pancreatic stenting papillectomy.

BACKGROUND: Although pancreatic stenting is recommended for the prevention of postprocedure pancreatitis during endoscopic papillectomy (EP), in some patients it is technically difficult to perform postprocedure insertion of a pancreatic stent after endoscopic resection. GOALS: This study assessed the feasibility of a novel EP for the purpose of reliable post-EP pancreatic stenting. STUDY: We conducted a prospective pilot study involving 10 consecutive patients with tumor of the major duodenal papilla. We developed a novel pancreatic stent, which is attached to a suture, and devised a method by which the stent is first placed at an upstream migration into the major pancreatic duct above the orifice before resection and then placed at an appropriate location after endoscopic resection by pulling the suture attached to the stent [inside pancreatic stenting papillectomy (IPSP)]. RESULTS: The pancreatic stent was successfully placed at an upstream migration into the pancreatic duct above the orifice in 9 of the 10 patients. For the 9 patients with successful pancreatic stent placement, IPSP was performed. Although the suture was cut in 1 patient, pancreatic stents could be placed appropriately across the orifice by pulling the suture in all patients. Although bleeding occurred in 3 patients, there was no pos-procedure pancreatitis. CONCLUSIONS: IPSP is a practicable method allowing reliable post-EP pancreatic stenting and can contribute to pancreatitis prevention. However, larger studies need to be performed before its use can be recommended.
