Abstract

Background/Purpose: A recent study has demonstrated that the timing of endoscopic ultrasound‐guided fine needle aspiration (EUS‐FNA) significantly influences the peritoneal lavage cytology (CY) outcomes in pancreatic body‐tail cancer. The aim of this study was to clarify the impact of EUS‐FNA on CY positivity in patients with resectable pancreatic body‐tail cancer. Methods: Patients with anatomically resectable pancreatic body‐tail cancer surgically resected at Hiroshima University Hospital were enrolled, and elated clinicopathological factors, including EUS‐FNA variables and CY positivity rate, were analyzed. Results: Of the 129 eligible patients, 16 (12%) had positive CY. The EUS‐FNA rates of the CY‐positive and CY‐negative groups were not significantly different (63% vs. 52%, p =.440). Multivariate analysis revealed that lymph node metastasis was the only independent risk factor for CY positivity (odds ratio: 5.734, p =.031). A total of 10 (14%) of the 69 patients who underwent EUS‐FNA had positive CY; however, needle specifications and the interval between EUS‐FNA and CY examination did not differ between the CY‐positive and CY‐negative groups. CY positivity rates were comparable for intervals ≤14 days and ≥15 days (17% vs. 14%, p = 1.000). Conclusions: EUS‐FNA may not affect CY positivity in patients with resectable pancreatic body‐tail cancer, regardless of the timing. [ABSTRACT FROM AUTHOR]

Abstract

Background/Purpose: Differential diagnosis of isolated immunoglobin (Ig)G4-related sclerosing cholangitis (IgG4-SC) and cholangiocarcinoma is challenging. We aimed to clarify the role of endoscopic retrograde cholangiography (ERCP)-related procedures in the differential diagnosis of isolated IgG4-SC and perihilar cholangiocarcinoma (PHCC). Methods: Seven patients with hilar-type isolated IgG4-SC diagnosed at Hiroshima University Hospital and sixty-five patients with surgically resected invasive PHCC were enrolled, and the diagnostic yields of intraductal ultrasonography (IDUS), peroral cholangioscopy (POCS), and pathological examinations were determined. Results: In six of seven (86%) patients with isolated IgG4-SC, the stricture was in the perihilar bile duct. IDUS showed that symmetrical wall thickening (40% vs. 5%, p = 0.04), homogeneous internal echo (80% vs. 5%, p < 0.001), and smooth outer margins (80% vs. 6%, p < 0.001) were more frequent in isolated IgG4-SC than in PHCC. POCS showed a smooth mucosal surface more frequent in isolated IgG4-SC (75% vs. 7%, p = 0.006). Only one patient had two pathological findings characteristic of IgG4-SC. The sensitivity for diagnosing PHCC was 81% using two or more combined sampling methods. Conclusions: Pathological examinations have limitations in the differential diagnosis of isolated-IgG4-SC and PHCC, and a diagnostic strategy that combines multiple ERCP-related procedures, including IDUS and POCS, is recommended.

Abstract

Background: The treatment of hepatolithiasis in patients who underwent hepaticojejunostomy (HJS) is challenging. In this study, we aimed to clarify the therapeutic outcomes of double balloon enteroscopy (DBE) and percutaneous transhepatic biliary drainage (PTBD) for hepatolithiasis after HJS. Methods: Patients who underwent DBE or PTBD for hepatolithiasis after HJS at Hiroshima University Hospital were enrolled, and treatment outcomes and recurrence were compared. Results: Forty-eight of the 84 eligible patients underwent DBE, with the HJS site reached in 42 patients (87.5%; DBE group). Forty-one patients underwent PTBD (PTBD group). There were no differences in the clinical characteristics and stone-related factors, including localization, maximum diameter, and quantity, between both groups. The complete stone removal rates in the DBE and PTBD groups were 85.7% and 90.2%, respectively. The DBE group had a significantly shorter median length of hospital stay than the PTBD group (6 vs. 21 days, P&lt; 0.001). During a median follow-up of 45 months, stone recurrence was observed in 22 (32.8%) patients. The cumulative recurrence rates at 1, 3, 5, and 10 years were 13.1%, 31.8%, 34.9%, and 52.7%, respectively. The stone recurrence rates of the DBE and PTBD groups were not significantly different (28.6% vs. 37.5%). Multivariate analysis revealed a stone diameter > 8 mm (hazard ratio, 2.602; P= 0.026) and age ≥ 70 years (hazard ratio, 3.077; P= 0.017) as independent risk factors for stone recurrence. Conclusions: DBE showed outcomes comparable to those of PTBD in the treatment of hepatolithiasis in patients who underwent HJS. Although reaching the HJS site is difficult in some cases, treatment can be completed within a short period with DBE; therefore, it could be the first choice of treatment for hepatolithiasis after HJS.

Abstract

Background and Purpose: The concept of early chronic pancreatitis was proposed in Japan with the aim to improve the prognosis of patients with chronic pancreatitis. Endoscopic ultrasonography plays an important role in early diagnoses, but is limited by its invasiveness and poor objectivity. Hence, this study aimed to determine the usefulness of transabdominal ultrasound real-time tissue elastography as a screening method for early chronic pancreatitis. Methods: We retrospectively examined 73 patients who underwent simultaneous ultrasound real-time tissue elastography and endoscopic ultrasonography from 2011 to 2014. The correlation between feature values (MEAN, %AREA, COMP) calculated by real-time tissue elastography and the Rosemont classification of endoscopic ultrasonography diagnostic criteria for chronic pancreatitis, and the diagnostic ability of ultrasound real-time tissue elastography to recognize “indeterminate for chronic pancreatitis” findings, which correspond to early chronic pancreatitis, were evaluated. Main Results: Based on the Rosemont classification, 26 patients were “normal”, 16 were “indeterminate for chronic pancreatitis”, 13 were “suggestive of chronic pancreatitis”, and 18 were “consistent with chronic ancreatitis”. There were significant correlations between the feature values (MEAN, %AREA, COMP) and the Rosemont classification (p < 0.001; ρ = –0.788, 0.779, and 0.489, respectively). The area under the curve for the ability of MEAN to diagnose “indeterminate for chronic pancreatitis” was 0.889 (sensitivity, 93.8%; specificity, 76.9%). Conclusions: The feature values calculated by ultrasound real-time tissue elastography were correlated with the Rosemont classification. Ultrasound real-time tissue elastography may be a useful screening method for early chronic pancreatitis.

Abstract

Background Although pegylated interferon (PEG-IFN) and nucleotide/nucleoside analogue (NA) combination therapy is considered to be optimal for accelerating serum hepatitis B surface antigen (HBsAg) reduction, the effect is limited, and the best approach to PEG-IFN treatment for chronic hepatitis B patients during long-term NA therapy has yet to be determined.Methods A total of 21 hepatitis B e antigen-negative chronic hepatitis B patients whose HBV DNA levels were suppressed to undetectable levels by NA therapy were administrated PEG-IFN-a2a for 48 weeks (sequential therapy: 10, add-on therapy: 11). Factors associated with HBsAg reduction by PEG-IFN therapy were analysed.Results During PEG-IFN treatment, HBsAg levels were reduced by 0.48 log IU/ml. More than 1 log IU/ml of HBsAg reduction was observed in eight patients (sequential therapy: six, add-on therapy: two), and one patient with sequential therapy achieved HBsAg loss. By univariate analysis, sequential therapy was marginally associated with more than 1 log IU/ml HBsAg reduction during PEG-IFN treatment (P=0.060). After PEG-IFN treatment, only five patients, including the patient with HBsAg loss, achieved more than 0.5 log IU/ml of HBsAg reduction by 1 year after PEG-IFN treatment. By univariate analysis, sequential therapy was significantly associated with HBsAg reduction after PEG-IFN treatment (P=0.012). In addition, alanine aminotransferase elevation during PEG-IFN therapy and lower serum interleukin-8 level at the end of PEG-IFN treatment were also significantly associated with HBsAg reduction by 1 year after PEG-IFN treatment (P=0.038, P=0.044, respectively).Conclusions Sequential therapy may be superior to addon therapy in reducing HBsAg levels during long-term NA therapy in chronic hepatitis B patients.
