Background/AimThe definition of muscle atrophy (pre-sarcopenia) and its diagnostic criteria have not been well reported. To elucidate the frequency of pre-sarcopenia in chronic liver disease (CLD), we examined clinical features of Japanese CLD patients using abdominal computed tomography (CT) findings.MethodsWe enrolled 988 CLD (736 with naïve hepatocellular carcinoma) and 372 normal control subjects (NCs). The psoas muscle area index [PI, psoas muscle area at the mid-L3 level in CT (cm2)/height (m)2] was calculated using personal computer software. The cut-off level for pre-sarcopenia was defined as less than two standard deviations (SDs) below the mean PI value in the NCs under 55 years old [males, 45.6 ± 5.7 years (n = 61), 4.24 cm2/m2; females, 47.0 ± 6.1 years (n = 49), 2.50 cm2/m2]. Elderly was defined as 65 years or older. Clinical features were retrospectively evaluated.ResultsIn the CLD group (HCV:HBV:HBV and HCV:alcohol:non-HBV and HCV = 652:88:7:82:159), pre-sarcopenia was observed in 15.3 % of patients with chronic hepatitis (CH), 24.4 % of those with liver cirrhosis (LC) Child-Pugh A, 37.7 % of those with LC Child-Pugh B, and 37.1 % of those with LC Child-Pugh C. A comparison between NC and CH by age (<55, 55–64, 65–74, ≥75 years) showed that the frequency of pre-sarcopenia was higher in CH regardless of age (1.8 vs. 3.6 %, 3.2 vs. 15.9 %, 4.9 vs. 13.4 %, 14.3 vs. 20.2 %, respectively). PI values showed correlations with BMI (r = 0.361), age (r = −0.167), albumin (r = 0.115), and branched-chain amino acids (r = 0.199) (P < 0.01).ConclusionRetrospective evaluate for pre-sarcopenia was easy to perform with CT findings. Nutrition and exercise instruction should be considered for early stage and even non-elderly CLD as well as LC.

Background and study aims Since per-oral endoscopic myotomy (POEM) was introduced in 2010, it has become accepted as one of the standard treatments for esophageal achalasia worldwide. This study aimed to present long-term clinical results of POEM over 10 years and evaluate the technique and outcomes at the institution where it was first used in clinical settings. Patients and methods Questionnaire-based surveys were sent to patients who received POEM in our institution from September 2008 to May 2010. Patient demographics and procedural outcomes and open-ended questions were posed about the postoperative courses, including symptom improvement and recurrence, additional treatments, and post-POEM gastroesophageal reflux disease (GERD) symptoms. Achalasia symptoms and post-POEM GERD symptoms were evaluated with Eckhardt scores and GerdQ systems, respectively. Results Thirty-six consecutive POEMs were performed in that period and 10-year follow-up data were obtained from 15 patients (41.7 %). Although four cases (26.7 %) required additional pneumatic balloon dilatation (PBD), reduction in post-Eckardt scores were observed in 14 cases (93.3 %). GerdQ score was positive in one patient (6.7 %). Proton pump inhibitors (PPI) were taken by four patients (26.7 %) and their symptoms were well-controlled. Conclusions Clinical results of POEM over 10 years were favorable regardless of various factors. Symptoms improved even in patients who required additional treatments, suggesting that POEM plays a significant role in treatment of achalasia.

Background/Aim: We examined tumor marker levels to assess in more detail transcatheter arterial chemoembolization (TACE)-refractory hepatocellular carcinoma (HCC). Materials and Methods: We enrolled patients treated from 2000 to 2011 for HCC beyond the Milan criteria who had good hepatic reserve function (Child-Pugh A) and no portal vein thrombosis or metastases (n = 154). The modified criteria for being TACE-refractory according to the Liver Cancer Study Group of Japan (m-LCSGJ), from which the tumor marker item was excluded, and the Assessment for Retreatment with TACE (ART) score were used for determining whether the HCC was TACE refractory. α-Fetoprotein ≥100 ng/ml, fucosylated α-fetoprotein ≥10%, and des-gamma-carboxy prothrombin ≥100 mAU/ml were used to define whether tumor markers were positive. We added up the number of positive tumor markers as a prognostic score to assess in more detail the evaluation of TACE-refractory HCC. Results: In order to divide the patients into a refractory and nonrefractory group, the m-LCSGJ criteria [mean survival time (MST) 27.1 vs. 49.9 months; p < 0.001] were superior to the ART score (MST 22.0 vs. 35.1 months; p = 0.051). In the refractory group according to the m-LCSGJ criteria, the patients with a low score of positive tumor markers (<2) after 2 sessions of TACE (n = 36) showed a better prognosis than the others (n = 72) (MST 37.7 vs. 23.2 months; p = 0.014). Conclusion: Patients being nonrefractory according to the m-LCSGJ criteria had a better response, and using the number of tumor markers (≥2) is an easy method for predicting the response to TACE and for a more detailed evaluation of TACE-refractory HCC.
