RESUMO

BACKGROUND: Balloon-occluded retrograde transvenous obliteration (BRTO) is an effective treatment for gastric varices, but predictors associated with overall survival rate (OS) and occurrence of esophagogastric varices (EGV) have not yet been clarified. In this study, we clarified these predictors by performing ultrasound elastography and blood tests at various time points. METHODS: A total of 34 patients were enrolled. The primary endpoint was to identify predictors associated with OS and EGV occurrence by univariate and multivariate analyses. Secondary endpoints were to extract the cut-off values for OS and EGV occurrence, and to clarify chronological changes in liver stiffness (LS), spleen stiffness (SS), spleen index (SI), and portal vein flow volume (PVF). Time points were set as before BRTO (Bf), and 1 day (D1), 7 days (D7), 1 month (1M), 3 months (3M), and 6 months (6M) after BRTO. RESULTS: Albumin-bilirubin score Bf, fibrin-4 index change 6M, and branched chain amino acids tyrosine molar ratio (BTR) 1M were predictors of OS on univariate analysis (P = .021, .033, and .019, respectively) but were not extracted by multivariate analysis. The factors of LS 6M > 19.9 kPa and SS D7 > 21.7 kPa were predictors of the occurrence of EGV on multivariate analysis (P = .029 and .025, respectively). PVF significantly increased with time after BRTO. CONCLUSION: Albumin-bilirubin score and BTR had the possibility to associate with OS, and the predictors of reduced occurrence of EGV were LS < 19.9 and SS < 21.7.

RESUMO

BACKGROUND/PURPOSE: Although the lumen-apposing metal stent (LAMS) is useful for interventional endoscopic ultrasound (EUS) procedures, there has been some concern about the potential for stent-induced adverse events because of the high lumen-apposing force. A newly designed LAMS with less lumen-apposing force has been developed for use with a physician-controlled electrocautery-enhanced delivery system. The aim of this animal study was to evaluate the feasibility of performing interventional EUS using this newly designed LAMS system. METHODS: Endoscopic ultrasound-guided cystogastrostomy was performed using the novel LAMS three times in a wet simulation model. EUS-guided gastroenterostomy and EUS-guided gallbladder drainage were then performed using the system in four pigs. RESULTS: The LAMS was successfully placed in all three EUS-guided cystogastrostomy procedures using the wet simulation model and in all four EUS-guided gastroenterostomy and gallbladder drainage procedures in the animal model. In the 3 weeks following the procedure, eating behavior was normal in all animals and there were no adverse events. The stents remained patent during this time and were removed without difficulty. The fistula was mature in all cases and a standard upper gastrointestinal endoscope was easily advanced via the fistula to observe the afferent and efferent loops or the lumen of the gallbladder. Necropsy confirmed complete adhesion between the stomach and the wall of the jejunum or gallbladder. CONCLUSIONS: Our study findings demonstrate the feasibility of this new LAMS system and its potential clinical value for interventional EUS.

RESUMO

BACKGROUND: Red dichromatic imaging (RDI) is a novel image-enhanced endoscopy released in 2020, which increases the visibility of deeper vessels. In this study, we retrospectively investigated whether RDI can shorten treatment times of endoscopic injection sclerotherapy (EIS), and which operational procedure times are affected compared with white light imaging (WLI). METHODS: A total of 155 patients (RDI, 70; WLI, 85) with risky esophageal varices (EV), who were treated with EIS were analyzed. Treatment times were compared, and predictors associated with treatment time were analyzed by multivariate analysis. For 24 cases (RDI, 12; WLI, 12) in which treatment videos were recorded, the procedure times of each step (observation of EV, needle flush, positioning, puncture, observation of bleeding, hemostasis, observation after hemostasis) were measured. Regarding the seven patients with EV bleeding, color differences were calculated between the bleeding point and the blood pool using the CIE (L*a*b*) color measurement method, and results were compared between using RDI and WLI. RESULTS: Treatment times were shorter in the RDI group (RDI vs. WLI = 35.1 vs. 42.2 min; P < 0.01). 'RDI function' and 'amount of sclerosant' were extracted as independent predictors of treatment time. Times for 'observation of EV' and 'observation of bleeding' were shorter in the RDI group (P = 0.01 and <0.01, respectively). Regarding the color difference, RDI significantly increased bleeding point visibility (RDI vs. WLI = 31.4 ± 11.8 vs. 8.6 ± 6.2, P < 0.001). CONCLUSION: Red dichromatic imaging can shorten the treatment time of EIS by increasing bleeding point visibility.

RESUMO

BACKGROUND: Peri-esophageal collateral veins have been reported to be associated with the recurrence of esophageal varices (EVs). In this study, we retrospectively analyzed whether endoscopic ultrasonography (EUS) findings obtained just before endoscopic injection sclerotherapy (EIS) are associated with the success rate of intravariceal injection, recurrence rate of EVs, and overall survival rate (OS) of patients. Furthermore, we investigated the independent predictors associated with these factors by multivariate analysis. METHODS: A total of 91 patients with risky EVs treated by EIS were analyzed. The primary endpoint was to identify independent predictors associated with the success rate of intravariceal injection, recurrence rate, and OS by multivariate analysis, to confirm the usefulness of EUS examination. The secondary endpoint was to clarify differences in recurrence rate and OS between patients who underwent additional argon plasma coagulation (APC) and those who did not, by the propensity score matching method. RESULTS: Luminal diameter of EVs and F factor were predictors of the success rate of intravariceal injection. APC was predictor of OS and recurrence of EVs. EUS findings were not associated with these factors. Propensity score matching (APC, 23; without APC, 23) showed that recurrence rate was significantly improved in the APC group (P = 0.050) and that OS had the tendency to be higher in the APC group (P = 0.068). CONCLUSION: Endoscopic ultrasonography findings before EIS were associated with successful intravariceal injection but were not associated with recurrence rate or OS. Additional APC could improve OS and reduce the recurrence of EVs.

RESUMO

BACKGROUND: Lusutrombopag effectively increases platelet count in patients with severe thrombocytopenia. However, no multicenter studies analyzing the effects of Lusutrombopag on patients with mild thrombocytopenia (platelet count > 50 000/µL) have been performed. In this study, we aimed to clarify the efficacy of Lusutrombopag on these patients by unifying background factors by propensity score matching. METHODS: A total of 139 patients with thrombocytopenia were enrolled, and matched for age, sex, etiology, disease, treatment, liver function, renal function, peripheral blood count, and spleen index. The primary endpoint was to compare the increase in platelet count from baseline between the high-platelet group (>50 000/µL) and the low-platelet group (<50 000/µL) after Lusutrombopag treatment, using propensity score matching. The secondary endpoint was to clarify platelet transfusion avoidance rate and adverse events, moreover, to identify independent predictors associated with the increase in platelet count. RESULTS: The mean increase in platelet count was 67 000/µL vs 48 000/µL in all patients (high- vs low-platelet group, P = .024), and 64 000/µL vs 48 000/µL (P = .12) after propensity score matching. The increase in platelet count and the platelet transfusion avoidance rate tended to be higher in the high-platelet group. There was no significant difference between adverse events. Predictors associated with an increase in platelet count were sex, estimated glomerular filtration rate, and spleen index by multivariate analysis. CONCLUSION: Lusutrombopag has a little stronger effect in patients with mild thrombocytopenia than those with severe thrombocytopenia and showed a more substantial effect in patients with impaired renal function and small spleen.

RESUMO

We herein report two cases of hemorrhagic ampullary lesions in which endoscopic papillotomy was performed to control bleeding and resulted in successful treatment. Both patients were pathologically diagnosed with an underlying pathology characterized by inflammatory cell infiltration and capillary proliferation. They also had disposing factors for bleeding, such as antithrombotic therapy and idiopathic thrombocytopenic purpura. Endoscopic treatment was selected because the risk of surgical resection was high due to the patients' hemorrhagic condition. Both patients were successfully treated without any serious adverse events and had an uneventful postoperative course with no relapse of bleeding.

RESUMO

A 67-year-old man with a history of esophageal and gastric varices that were treated endoscopically was treated for Budd-Chiari syndrome and immunoglobulin G4-related sclerosing cholangitis in our facility. Varices in the second portion of the duodenum were revealed in follow-up upper endoscopy. The draining vein formed a venous plexus that was detected on computed tomography. Treatment with interventional radiology was difficult;therefore, endoscopic injection sclerotherapy (EIS) was performed instead. No recurrence has been observed to date. Thus, in this case, EIS for duodenal varices was effective.

RESUMO

BACKGROUND: Data regarding the influence of patatin-like phospholipase domain-containing 3 (PNPLA3) polymorphism for patients with liver cirrhosis (LC) are scarce. OBJECTIVE: This study assesses the role of the PNPLA3 polymorphism for the development of LC and its complications by the findings of genetic examinations. METHODS: Patients with LC caused by virus (n = 157), alcohol (n = 104), nonalcoholic fatty liver disease (NAFLD) (n = 106), or autoimmune disease (n = 33) and without LC (n = 128) were enrolled. LC were composed of the present and absent of complications, such as variceal bleeding, hepatic ascites, and/or hepatic encephalopathy. To assess the role of the PNPLA3 polymorphism, odds ratio (OR) for the rs738409 variant was calculated for the patients between (i) with LC and without LC in the entire cohort, and (ii) the present and absent of complications in the patients with LC. RESULTS: There was a significant difference among the patients without LC and those with alcohol, NAFLD related LC in the frequency of G alleles (p < 0.001, both). According to complications of LC, the OR for NAFLD related cirrhosis significantly increased in the presence of the two mutated alleles (OR = 3.165; p = 0.046) when the wild type was used as the reference. However, there were no significant risks for the complications in the virus and alcohol related cirrhosis unless there was a presence of G alleles. CONCLUSION: The PNPLA3 polymorphism was associated with the risk of NAFLD related LC and its complications.

RESUMO

BACKGROUND/PURPOSE: We developed EUS-guided double-balloon occluded gastrojejunostomy (EPASS) for gastric drainage tract obstruction. The success of EPASS depends on the proximity of the stomach and the gastrointestinal (GI) tract near the ligament of Treitz. The aim of this study is to clarify the GI anatomy near the ligament of Treitz. METHODS: One thousand and sixteen cases imaged upper GI radiography using barium were retrospectively evaluated. Morphologically, the GI tract running near the ligament of Treitz was divided in three types: Type I: The 4th portion of the duodenum (D4) approaches the stomach; Type II: D4 does not approach the stomach; Type III: D4 forms a loop to the jejunum. The minimum distance between the stomach and the GI tract near the ligament of Treitz was measured. RESULTS: Based on the morphological classification, 74.6% in the study group was classified in Type I, 22.0% in Type II, and 3.3% in Type III, respectively. The median minimum distance in Type II/III group were significantly longer, compared with the Type I (P < .01). CONCLUSIONS: The GI anatomy near the ligament of Treitz was clarified using upper GI radiography. It is divided into three patterns, and one-fourth of cases may have difficulty in EUS-guided gastrojejunostomy.

RESUMO

PURPOSE: Measurement of spleen stiffness (SS) using ultrasound (US) elastography is useful for predicting portal hypertension. However, the mechanism leading to increased SS remains unclear. We jointly developed a new US elastography system (Aplio i-series, Canon Medical Systems) that can easily measure organ viscosity (dispersion slope: DS). We analyzed the cause of increased SS by calculating the shear wave speed (SWs, which reflects fibrosis) and DS of the spleen in carbon tetrachloride (CCL4) rat liver cirrhosis models. METHODS: A total of 13 Sprague-Dawley rats were randomly divided into four groups (C group: 3 rats as control, 2D group: 3 rats injected with CCL4 twice in 1 week, 4D group: 4 rats injected 4 times in 1 week, 6W group: 3 rats injected twice a week for 6 weeks). The SWs and the DS of each group were calculated, and histopathological analysis was performed. RESULTS: The spleen SWs of the 6W group was significantly higher than that of the C group (p = 0.044). The spleen DS did not change after CCL4. The liver SWs of the 4D and 6W groups was significantly higher than that of the C group (p = 0.012 and 0.007, respectively) with fibrosis change on histopathology, and the DS of the 4D group was significantly higher than that of the C group (p = 0.033). Splenic fibrosis was confirmed in the 6W group, but inflammation and necrosis were not seen. CONCLUSION: SS increased due to fibrosis and can be predicted based on SWs and DS values.

RESUMO

BACKGROUND: Red dichromatic imaging (RDI) is next-generation image-enhanced endoscopy technique released in July 2020. We previously reported that RDI can predict esophageal varices (EV) depth and decrease their recurrence rate by accurate intravariceal injections during endoscopic injection sclerotherapy (EIS) using unreleased prototype RDI endoscope. In this study, we analyzed whether RDI improves the overall survival (OS) rate and whether it is more accurate independent predictor of EV recurrence than white light imaging (WLI), using propensity score matching. METHODS: A total of 179 patients were enrolled. Patients were matched for age, platelet count, liver function, EV size, luminal diameter, and EV depth using propensity score matching, and 78 patients (RDI, 39; WLI, 39) were finally matched. Primary endpoints were OS and recurrence rates. Secondary endpoints were success rate of intravariceal injection, operating time, incidence of adverse events (AEs), and predictors associated with OS and recurrence rates. RESULTS: There was no difference in OS (P = .193), but the cumulative recurrence rate in the RDI group was significantly lower than in the WLI group (P = .002). Success rates of intrainjection, operating time, and incidence of AEs were better in the RDI group (p = 0.035, .026, and .0019, respectively). Independent predictors associated with recurrence rate by Cox proportional regression were RDI function and luminal diameter (P < .001 and .017, respectively). CONCLUSION: RDI did not improve OS but decreased the recurrence rate. Independent predictors of recurrence rate were RDI and luminal diameter, resulting from secure intravariceal injections in EIS.

RESUMO

BACKGROUND: The thrombopoietin (TPO) receptor agonist lusutrombopag was developed to treat thrombocytopenia in chronic liver disease (CLD). However, its effectiveness remains unclear. The purpose of this study was to assess the efficacy of lusutrombopag and identify predictors associated with increase in platelet count. METHODS: Eighty CLD patients with thrombocytopenia were enrolled. The primary endpoint was a satisfactory increase in platelets (greater than 1.0 × 104/µL from baseline) in the absence of platelet transfusion. The secondary endpoints were response rate (an increase of greater than 1.0 × 104/µL from baseline), independent predictors of increase in platelets, and the superiority of lusutrombopag over platelet transfusion. RESULTS: The primary endpoint was achieved in 93.8% (75 of 80) patients. The response rate was 96.2% (77 of 80). Renal function parameters (blood urea nitrogen, creatinine, eGFR) were significantly negatively associated with platelet count (p = 0.033, 0.049, and 0.0014, respectively) and were identified as independent predictors by multiple regression analysis (p = 0.049, 0.0023, and 0.0016, respectively). The median increase in platelet count was significantly higher after lusutrombopag than after platelet transfusion (41,000 vs. 12,000/µL, p = 0.015). CONCLUSION: Lusutrombopag was more effective than platelet transfusion for CLD patients, and renal function independently predicted increase in platelet count. Renal function parameters were significantly associated with platelet count.

RESUMO

AIM: The thrombopoietin receptor agonist, lusutrombopag, was recently adapted for treatment of thrombocytopenia in chronic liver disease. However, no studies have compared the effects of lusutorombopag and platelet transfusion. Therefore, we aimed to clarify the efficacy and proportion of responders of lusutrombopag compared with platelet transfusion, by propensity score matching. METHODS: A total of 200 patients (90 lusutrombopag, 110 platelet transfusion) with thrombocytopenia were enrolled, and matched for age, liver function, renal function, platelet count, peripheral blood count, and spleen size, using the propensity score-matching method. Finally, 52 patients (26 lusutrombopag, 26 platelet transfusion) were included. The primary end-point was an increase in platelet count. Secondary end-points were the proportion of responders, duration of the sustained effect, incidence of adverse events, and predictors associated with an increase in platelet count. RESULTS: The median increase in platelets from baseline was 48 × 103 /µL versus 9.5 × 103 /µL (lusutrombopag vs. transfusion, P < 0.0001). The proportion of responders (increase of >10 × 103 /µL) was 100% versus 50.0% (P < 0.0001). Median duration of the sustained effect (increase of >50 × 103 /µL) was 10 versus 2 days (P < 0.0001). The incidence of adverse events was 7.7% versus 50.0% (P = 0.036). Predictors associated with an increase in platelets were hemoglobin and spleen size by multiple regression analysis. CONCLUSION: Lusutrombopag was more effective in chronic liver disease patients than platelet transfusion. The proportion of responders, effect duration, and non-incidence rate of adverse events were higher in the lusutrombopag group.

RESUMO

BACKGROUND: Autotaxin (ATX) has been reported as a direct biomarker for estimating the evaluation of liver fibrosis. But available data on ATX as a useful biomarker for the complications of liver cirrhosis (LC) are scant. AIM: To assess the clinical usefulness of ATX for assessing the complications of LC. METHODS: This multicenter, retrospective study was conducted at six locations in Japan. We include patients with LC, n = 400. The ATX level was evaluated separately in men and women because of its high level in female patients. To assess the clinical usefulness of ATX for the complications of LC, the area under the curve (AUC) of ATX assessing for the severe complications was analyzed in comparison with the model for end-stage liver disease score, albumin-bilirubin (ALBI) score, fibrosis-4 index, and aspartate aminotransferase-to-platelet ratio index. RESULTS: The mean age was 68.4 ± 11.4 years, 240 patients (60.0%) were male. A total of 213 (53.3%) and 187 (46.8%) patients were compensated and decompensated, respectively. The numbers of patients with varix rupture, hepatic ascites, and hepatic encephalopathy were 35 (8.8%), 131 (32.8%), and 103 (25.8%), respectively. The AUCs of ATX in men for hepatic encephalopathy, hepatic ascites, and varix ruptures were 0.853, 0.816, and 0.706, respectively. The AUCs of ATX in women for hepatic encephalopathy, hepatic ascites, and varix rupture were 0.759, 0.717, and 0.697, respectively. The AUCs of ATX in men were higher than those in women, as were all the other biomarkers used to detect encephalopathy and varix ruptures. However, for detecting ascites, the AUC of ALBI in men was more effective than using ATX. CONCLUSION: ATX in men was more effective than any other biomarkers for detecting hepatic encephalopathy and varix ruptures.
