Asians are known to be more likely than Westerners to develop fatty liver and lifestyle-related diseases in spite of their weight. However, the relationship between fat accumulation and lifestyle-related diseases in non-obese Asians is unknown. Therefore, this study aimed to analyze visceral fat and hepatic fat in participants with a normal body mass index (BMI) and examine their characteristics during a medical checkup. This cross-sectional study was conducted on 663 of 1142 patients who underwent abdominal ultrasonography and who had an alcohol intake (converted to ethanol) of 2 during a health checkup. Participants were classified into four groups: group A, visceral fat accumulation (VFA) (−) and fatty liver (FL) (−) (n = 549); group B, VFA (+) and FL (−) (n = 32); group C, VFA (−) and FL (+) (n = 58); and group D, VFA (+) and FL (+) (n = 24). The frequencies of lifestyle-related disease complications, liver function tests, and liver fibrosis were evaluated among the four groups. Compared with group A (control), groups B, C, and D had a higher number of males, BMI, abdominal circumference, ALT, AST, γ-GTP, triglyceride, uric acid, fasting blood sugar levels, and incidence of hyperlipidemia. Groups C and D had higher ALT, HbA1c, cholinesterase, and triglyceride levels, FIB4 index, and the number of patients with diabetes mellitus (DM) than groups A and B; however, there was no difference between groups A and B. FL is a risk factor of DM and liver fibrosis in non-obese Japanese individuals; however, VFA only is not a risk factor of DM and liver fibrosis.

Background: Endoscopic sphincterotomy (EST) is currently recognized as the primary endoscopic treatment for common bile duct stones. However, it is difficult to remove multiple (≥3) or large (≥15 mm) common bile duct stones with EST alone. Recently, EST plus endoscopic papillary large-balloon dilation (EPLBD) was reported to be an effective treatment for such bile duct stones. We compared the results of EST and EST + EPLBD for multiple (≥3) or large (≥15 mm) stones that were difficult to treat using EST alone. We also compared the complication rates between the techniques. Methods: Seventy patients with large (largest diameter, ≥15 mm) or ≥ 3 common bile duct stones treated in our department between April 2010 and March 2013 underwent EST + EPLBD (n = 34) or EST alone (n = 36). We compared final successful stone removal rates, rates of successful stone removal in the first session, procedure times, status of concurrent mechanical lithotripsy (ML), and complications between the EST + EPLBD and EST groups. Results: The rates of final successful stone removal were similar between the two groups (EST + EPLBD: 100 % vs. EST: 89 %; p = 0.115). The rate of successful stone removal in the first session was significantly higher in the EST + EPLBD group (EST + EPLBD: 88 % vs. EST: 56 %; p =0.03).Moreover, theprocedure time was significantly shorter (EST + EPLBD: 42 min vs. EST: 67 min; p = 0.011) and the rate of ML use was significantly lower in the EST + EPLBD group (EST + EPLBD: 50 % vs. EST: 94 %; p < 0.001). Complications like pancreatitis and bleeding occurred in three patients in the EST + EPLBD group and in 10 patients in the EST group, but the differences were not statistically significant (EST + EPLBD: 9 % vs. EST: 25 %; p = 0.112). Conclusions: Our results suggest that EST + EPLBD is an effective therapy for patients with difficult-to-treat multiple or large common bile duct stones, because it requires fewer sessions and shorter operative times than EST alone.

Background: Gastric endoscopic submucosal dissection (ESD) has gradually come to be recommended as the optimal treatment for early gastric cancer; however, one of the primary issues is postoperative bleeding. Although second-look endoscopy is conventionally performed to reduce the risk of postoperative bleeding, its benefit has not yet been clearly elucidated. The objective of this study was to elucidate the benefit of second-look endoscopy. Methods: A total of 459 lesions in patients were underwent gastric ESD from May 2004 to April 2013 at our hospital were included in the analysis. The patients were divided into those who had bleeding within 24 hours after ESD (immediate bleeding) and those in whom bleeding occurred 24 hours or more after the procedure (delayed bleeding); the underlying disease, age, lesion site, diameter of the resected specimen, and lesion diameter were analyzed to identify the risk factors for postoperative bleeding after ESD. Results: Post-ESD immediate or delayed bleeding occurred in 23 of the 459 cases (5.0%). Second-look endoscopy was performed in 210 of 447 cases (47.0%) excluding 12 cases with immediate bleeding; in the remaining 237 of the 447 cases (53.0%), it was not performed. Post-ESD delayed bleeding occurred in 6 of the 210 cases (2.9%) and 5 of the 237 cases (2.1%), with no statistically significant difference between the two groups. Overall, the following factors were identified as the risk factors for postoperative bleeding: young age (P = 0.005), lesions in the L segment (P = 0.042), and large size of the resected specimen (P = 0.005). The risk factors identified in the immediate bleeding group were lesions in the L segment (P = 0.032), large size of the resected specimen (P < 0.001), and large tumor size (P = 0.011), and those in the delayed bleeding group were young age (P = 0.013) and concomitant renal disease (P = 0.011). Conclusions: The results of this study suggest that second-look endoscopy after gastric ESD may not be useful for preventing postoperative bleeding. [ABSTRACT FROM AUTHOR]
