RESUMEN
A 79-year-old male patient presented to our hospital with chief complaints of fever, abdominal pain, and jaundice. Laboratory data revealed marked hepatobiliary enzyme and inflammatory marker elevations, and computed tomography revealed ascending colon diverticulitis, thrombophlebitis, portal vein thrombus, and intrahepatic cholangitis. Blood culture revealed the presence of Prevotella sp. The patient was treated with anticoagulant therapy in addition to antimicrobial therapy;however, activated partial thromboplastin time prolongation remained insufficient. Antithrombin therapy was combined with the current therapy because antithrombin levels were low, which resulted in iliopsoas muscle hematoma. The hematoma resolved conservatively after discontinuing anticoagulation, and the patient was discharged after 19 days of hospitalization with improved cholangitis and diverticulitis. The portal vein thrombus remained after discharge;however, anticoagulation therapy was not restarted due to adverse events. This case was presented because of its difficult treatment.

During a medical health check, a 29-year-old man was presented to our hospital with iron deficiency anemia. He had no significant medical history in his family. Despite being diagnosed with ocular sarcoidosis 5 years ago, he had no vision problems. Physical examination revealed normal vital signs and a nontender abdomen;however, his eyelid conjuvitis was pale, and he became aware of fatigue when moving vigorously. He had upper gastrointestinal endoscopy and colonoscopy, but there was no evidence of bleeding detected. A contrasted mass 30mm in size was discovered on abdominal contrast-enhanced computed tomography at the dorsal wall of the proximal jejunum. Positron emission tomography showed an accumulation image in the bilateral hilar lymph and upper jejunum. A 30-mm submucosal tumor with a central depression in the upper jejunum was discovered using a double-balloon enteroscopy. We performed biopsies from the depression margin and tattoo marking on the oral side of the tumor. Even though the biopsies specimen revealed granulation tissue, the patient was referred to surgery and underwent a partial jejunum resection because the tumor was diagnosed as the cause of anemia. The operation went smoothly, and the patient was discharged on the seventh postoperative day. Histological examination showed a proliferation of densely packed spindle cells with prominent nuclear palisading. The immunohistochemical examination revealed that c-kit and CD34 were highly expressed, whereas desmin and S-100 proteins were not. Ki-67 expression demonstrated a very low proliferative index (2%). We discovered gastrointestinal stromal tumors (GIST), as well as an ectopic pancreas. GIST is extremely rare in young people, and the coexistence of ectopic pancreas and sarcoidosis has never been reported.

BACKGROUND AND AIM: Endoscopic nasobiliary drainage (ENBD) is often recommended in preoperative biliary drainage (PBD) for hilar malignant biliary obstruction (MBO), but endoscopic biliary stent (EBS) is also used in the clinical practice. We conducted this large-scale multicenter study to compare ENBD and EBS in this setting. METHODS: A total of 374 cases undergoing PBD including 281 ENBD and 76 EBS for hilar MBO in 29 centers were retrospectively studied. RESULTS: Extrahepatic cholangiocarcinoma (ECC) accounted for 69.8% and Bismuth-Corlette classification was III or more in 58.8% of the study population. Endoscopic PBD was technically successful in 94.6%, and adverse event rate was 21.9%. The rate of post-endoscopic retrograde cholangiopancreatography pancreatitis was 16.0%, and non-endoscopic sphincterotomy was the only risk factor (odds ratio [OR] 2.51). Preoperative re-intervention was performed in 61.5%: planned re-interventions in 48.4% and unplanned re-interventions in 31.0%. Percutaneous transhepatic biliary drainage was placed in 6.4% at the time of surgery. The risk factors for unplanned procedures were ECC (OR 2.64) and total bilirubin ≥ 10 mg/dL (OR 2.18). In surgically resected cases, prognostic factors were ECC (hazard ratio [HR] 0.57), predraiange magnetic resonance cholangiopancreatography (HR 1.62) and unplanned re-interventions (HR 1.81). EBS was not associated with increased adverse events, unplanned re-interventions, or a poor prognosis. CONCLUSIONS: Our retrospective analysis did not demonstrate the advantage of ENBD over EBS as the initial PBD for resectable hilar MBO. Although the technical success rate of endoscopic PBD was high, its re-intervention rate was not negligible, and unplanned re-intervention was associated with a poor prognosis in resected hilar MBO.

AIM: To optimize the therapeutic efficacy of NS3/4A protease inhibitors, a multicenter prospective study was performed according to an algorithm based on the Adherence, IL-28B Gene Allele and Viral Response Trial (AG & RGT). METHODS: A total of 340 patients with genotype 1b hepatitis C virus (HCV) showing serum RNA levels of >5 log were enrolled. The duration of ribavirin/pegylated interferon (PEG IFN)-α-2b therapy was prolonged to 48 weeks in patients with unfavorable IL28B alleles showing adherence rates of less than 80% for either drug during the first 12 weeks even if RVR had been achieved, and in those in whom cEVR, but not RVR, was achieved; furthermore, to 72 weeks in those showing partial early viral response. RESULTS: The therapeutic outcomes were assessed in 282 patients, and the therapy was set to complete at 24 weeks in 181 patients (64%) and to prolong to 48 weeks or 72 weeks in 71 patients (25%). The former group showed a SVR rate of 84%, while the latter group showed an SVR rate of 69% with a relapse rate of 7%. The SVR rate was 33% in the 30 patients (11%) in whom the therapy had to be discontinued in less than 12 weeks. Thus, the results of intention-to-treat analysis revealed an overall SVR rate of 75%. Multivariate analysis identified prolongation of the duration of therapy as a significant factor associated with SVR. CONCLUSION: Triple therapy yielded a high SVR rate in the AG & RGT trial via attenuation of viral relapse by prolonged ribavirin/PEG IFN-α-2b administration. © 2015 The Japan Society of Hepatology.
RESUMEN
AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction. METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent (PS) or nasobiliary catheter (NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedure-related adverse events, stent/catheter dysfunction (occlusion or migration of PS/NBC, development of cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution (bilirubin level < 3.0 mg/dL) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis. RESULTS: In total, 419 patients were included in the study (PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients (46%), bile duct cancer in 172 (41%), gallbladder cancer in three (1%), and ampullary cancer in 50 (12%). The median serum total bilirubin was 7.8 mg/dL and 324 patients (77%) had ≥ 3.0 mg/dL. During the median time to surgery of 29 d [interquartile range (IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio (SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method (PS or NBC). CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored.

OBJECTIVE: A multicenter open trial was performed to clarify the optimal duration of combined pegylated interferon (Peg-IFN) plus ribavirin therapy in patients with chronic hepatitis caused by HCV genotype 2. METHODS: A total of 100 patients seen between 2005 and 2007 received the combination therapy for 4 to 52 weeks. The cutoff value of the HCV-RNA-negative (titers under 1.7 Log IU/mL) period during the therapy to predict sustained virological response (SVR) was determined by ROC curve and multivariate logistic regression analyses. The result was validated in 48 patients between 2008 and 2009. RESULTS: SVR was achieved in 78 patients. Serum HCV-RNA titers decreased to less than 1.7 Log IU/mL at 4 weeks of the therapy in 60 patients. The SVR rate in these patients was 85%, which was significantly higher than that of remaining 40 patients with a SVR rate of 68%. An HCV-RNA-negative period of ≥17 weeks was selected as the cutoff value, which showed a significant odds ratio of 4.77 for SVR. Among the 35 patients who showed a decrease of the serum HCV-RNA of less than 1.7 Log IU/mL between 8 and 16 weeks of therapy, the SVR rate was significantly higher in 16 patients with a serum HCV-RNA-negative period of ≥17 weeks (94%) than in 19 patients in whom the period was less than 17 weeks (63%). Similar results were obtained in the subsequent validation study. CONCLUSION: Prolonged combined Peg-IFN plus ribavirin therapy, with an HCV-RNA-negative period of ≥17 weeks, yielded good therapeutic outcomes in patients with chronic HCV genotype 2 hepatitis.
