A combination of HPA and serum PG assays, plus scheduling endoscopy accordingly, is a cost-effective method of screening for gastric cancer risk in Japan.
Background Delayed bleeding is an important complication after gastric endoscopic submucosal dissection (ESD). The search, coagulation, and clipping (SCC) method can be used to prevent delayed bleeding after ESD. However, its safety and efficacy are unclear. We compared the SCC method with post-ESD coagulation (PEC) to clarify the safety and efficacy of the SCC method for preventing delayed bleeding after gastric ESD. Methods This retrospective study included 438 patients (478 lesions) who underwent gastric ESD. Multivariate logistic regression analysis was performed to identify the significant independent factors associated with delayed bleeding and we performed propensity-score matching (PSM) to reduce the effect of procedure-selection bias of SCC method. Results Of the 438 patients, 216 underwent PEC and 222 underwent SCC. Delayed bleeding was significantly less common in the SCC than in the PEC (2.6% vs. 7.2%; P = 0.013). Among patients treated with antithrombotic therapy, the delayed bleeding rate was lower in the SCC group than in the PEC group; however, the difference was not significant ( P = 0.15). The SCC method was found to be a significant independent factor for the prevention of delayed bleeding. PSM was performed in 156 patients in the PEC group and SCC group. There was a significant difference in the incidence of bleeding in the PEC and SCC groups ( P = 0.013). No patient had perforation/bleeding associated with the SCC method. Conclusions Our findings suggest that the SCC method is a simple, safe, and effective approach for preventing delayed bleeding after gastric ESD.
Objective Rifaximin has become available for treating hyperammonemia in patients with hepatic encephalopathy. This study analyzed the changes in the body composition and nutritional status after long-term rifaximin therapy. Methods Twenty-one patients who underwent rifaximin therapy at 1,200 mg/day for more than 24 weeks were evaluated for the changes in the controlling nutritional status (CONUT) scores for the nutritional assessment, albumin-bilirubin (ALBI) scores for the liver function assessment, and skeletal muscle index (SMI) for the body composition assessment. Results There were 17 men and 4 women, with a mean age of 67.14±8.32 years. Eleven cases had a portosystemic shunt (52.3%), and 10 had hepatocellular carcinoma (47.6%). The Child-Pugh class was A in 9 cases (42.9%), B in 9 cases (42.9%), and C in 3 cases (14.2%). The blood ammonia levels in the rifaximin group improved significantly upon rifaximin therapy, from 124.76±28.68 μg/dL at baseline to 47.00±14.43 μg/dL after 2 weeks (p<0.001) and 49.81±15.02 μg/dL after 24 weeks (p<0.001). The CONUT scores improved significantly during rifaximin therapy, from 6.47±3.25 at baseline to 3.33±2.65 after 24 weeks (p=0.0007). The ALBI scores also improved significantly from -0.39±1.89 at baseline to -2.20±0.55 after 24 weeks (p=0.0002). The SMI scores showed that the body composition had been maintained in response to rifaximin therapy (50.20±7.67 at baseline and 51.29±7.62 after 24 weeks). Conclusion Rifaximin administration for hepatic encephalopathy improved the CONUT and ALBI scores. It may have a secondary effect on the improvement in the nutritional status and hepatic reserve.
Objective Tolvaptan (TVP) is an effective treatment for patients with cirrhotic ascites; however, studies have indicated that a sufficient effect is difficult to obtain in patients with hepatocellular carcinoma (HCC). This study evaluates the efficacy of TVP in patients with HCC with refractory ascites. Methods We retrospectively enrolled 32 patients with liver cirrhosis and refractory ascites [mean age: 74 years (range, 47–86 years), men: 78.1% (25/32)]. All patients had HCC and were treated with TVP at our hospital. A TVP responder was defined as a patient who experienced decrease in body weight by ≥1.5 kg within 1 week of treatment. Univariate and multivariate analyses were performed to evaluate clinical and laboratory predictive factors of TVP response. Results The TVP response rate was 46.9% (15/32 patients) after 1 week of treatment. HCC treatment (transcatheter arterial chemoembolization and/or radiofrequency ablation) was administered to 11/15 (73.3%) responders. In the multivariate analysis, the reduction of urine osmolality was higher in responders than nonresponders (202 mOsm/l vs. 65 mOsm/l, P = 0.040), and the tumor stage (P = 0.043) was worse in nonresponders. Multivariate Cox proportional hazards regression analysis indicated a significantly better prognosis among responders than among nonresponders (P < 0.01). Conclusion The HCC tumor stage and the reduction in urine osmolality can predict the efficacy of TVP in patients with refractory ascites complicated with HCC. TVP may allow therapeutic intervention for HCC and improve prognosis, even in patients with Child–Pugh class C.
