Association between non-alcoholic fatty liver disease and coronary artery disease outcomes: A systematic review and meta-analysis.

OBJECTIVES: To evaluate the association between non-alcoholic fatty liver disease (NAFLD) and cardiovascular outcomes, including angina, coronary artery disease (CAD), coronary artery calcification (CAC), myocardial infarction (MI), and calcified coronary plaques. METHODS: A comprehensive search of databases, including PubMed, EMBASE, and Cochrane Library, was conducted up to January 2023. Studies were included investigating the relationship between NAFLD and cardiovascular outcomes in adult populations. Exclusion criteria were studies on animals, pediatric populations, and those not published in English. Two reviewers assessed the risk of bias in the included studies using the Newcastle-Ottawa Scale. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects models. RESULTS: The meta-analysis included 32 studies with a total of 5,610,990 participants. NAFLD demonstrated significant associations with increased risks of angina (Relative Risk (RR): 1.45, 95% CI: 1.17, 1.79), CAD (RR: 1.21, 95% CI: 1.07, 1.38), CAC >0 (RR: 1.39, 95% CI: 1.15, 1.69), and calcified coronary plaques (RR: 1.55, 95% CI: 1.05, 2.27). However, no significant association was found between NAFLD and CAC >100 (RR: 1.16, 95% CI: 0.97, 1.38) or MI (RR: 1.70, 95% CI: 0.16, 18.32). CONCLUSION: The meta-analysis demonstrated a significant association between NAFLD and cardiovascular outcomes independent of conventional cardiovascular disease (CVD) risk factors. These findings emphasize the importance of prevention, early detection, and proper management of NAFLD.

Endoscopic ultrasound-guided hepaticogastrostomy by puncturing both B2 and B3: a single center experience.

Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) through ducts B2 or B3 is effective in most patients with biliary obstruction, because B2 and B3 commonly join together. However, in some patients, B2 and B3 do not join each other due to invasive hilar tumors; therefore, single-route drainage is insufficient. Here, we investigated the feasibility and efficacy of EUS-HGS through both B2 and B3 simultaneously in seven patients. We decided to perform EUS-HGS through both B2 and B3 to achieve adequate biliary drainage because these two ducts were separate from each other. Here, we report a 100% technical and overall clinical success rate. Early adverse effects were closely monitored. Minimal bleeding was reported in one patient (1/7) and mild peritonitis in one patient (1/7). None of the patients experienced stent dysfunction, fever, or bile leakage after the procedure. EUS-HGS through both B2 and B3 simultaneously is safe, feasible, and effective for biliary drainage in patients with separated ducts.

Utility of forward-view endoscopic ultrasound in fine-needle aspiration in patients with a surgically altered upper gastrointestinal anatomy.

BACKGROUND/AIMS: Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) using oblique-view EUS in patients with a surgically altered anatomy (SAA) of the upper gastrointestinal tract is limited because of difficult scope insertion due to the disturbed anatomy. This study aimed to investigate the efficiency of forward-view (FV)-EUS in performing FNA in patients with a SAA. METHODS: We retrospectively investigated 32 patients with a SAA of the upper gastrointestinal tract who visited Aichi Cancer Center Hospital in Nagoya, Japan, between January 2014 and December 2020. We performed-upper gastrointestinal EUS-FNA using FV-EUS combined with fluoroscopic imaging to confirm tumor recurrence or to make a decision before chemotherapy or after a failure of diagnosis by radiology. RESULTS: We successfully performed EUS-FNA in all studied patients (100% technical success), with the specificity, sensitivity, and accuracy of 100%, 87.5%, and 87.8%, respectively, with no complications. CONCLUSION: EUS-FNA using FV-EUS combined with fluoroscopic imaging is an effective and safe technique for tissue acquisition in patients with a SAA.

Impact of socioeconomic status and sibling number on the prevalence of Helicobacter pylori infection: a cross-sectional study in a Japanese population.

Helicobacter pylori infection is a significant risk factor for gastric cancer. The infection is acquired mainly in early childhood and is influenced by environmental factors, including socioeconomic status and sibling number. However, the impact of socioeconomic status and sibling number on Helicobacter pylori infection has not been well studied in Japan. We conducted a cross-sectional study to evaluate the impact of socioeconomic status, represented by education level, and sibling number on the prevalence of Helicobacter pylori infection among 3,423 non-cancer subjects who visited Aichi Cancer Center between 2005 and 2013. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using a logistic regression model adjusted for potential confounding variables. Of the 3,423 subjects, 1,459 (42.6%) were Helicobacter pylori-positive. The prevalence of Helicobacter pylori infection linearly decreased with increasing socioeconomic status [ORs (95% CIs) of moderate and high socioeconomic status relative to low socioeconomic status of 0.67 (0.53-0.84) and 0.43 (0.34-0.54), respectively; P trend=9.7×10-17]. In contrast, the prevalence of Helicobacter pylori infection linearly increased with increasing sibling number [ORs (95% CIs) of SN 3-4 and ≥5 relative to sibling number ≤2 of 1.74 (1.47-2.06) and 2.54 (2.12-3.04), respectively; P trend=1.2×10-24]. This study showed that socioeconomic status and sibling number were significantly associated with the prevalence of Helicobacter pylori infection.

B2 puncture with forward-viewing EUS simplifies EUS-guided hepaticogastrostomy (with video).

Background and Objectives: EUS-guided hepaticogastrostomy (EUS-HGS) is in widespread use; however, there are few dedicated devices. The B2 route is technically easier than the B3 route for guidewire insertion, dilation, and stenting but if performed with conventional oblique-viewing (OV) EUS, B2 puncture can cause transesophageal puncture and severe adverse events. The aim of this study was to assess the efficacy of forward-viewing (FV) EUS, which we have developed to improve safety for B2 puncture in EUS-HGS (B2-EUS-HGS). Patients and Methods: This single-center retrospective study included 61 consecutive patients who underwent B2-EUS-HGS with FV between February 2020 and March 2021 at Aichi Cancer Center, Japan. The patients were prospectively enrolled, and clinical data were retrospectively collected for these 61 cases. Results: The overall technical success rate of EUS-HGS was 98.3% (60/61). The rate of EUS-HGS with FV was 95.0% (58/61) after three cases converted to OV, and that of B2-EUS-HGS with FV was 88.5% (54/61). The early adverse event rate was 6.5% (4/61). There were no instances of transesophageal puncture. Median procedure time was 24 min (range, 8-70), and no patient required cautery dilation. Conclusions: B2-EUS-HGS can be performed safely using FV, without transesophageal puncture, and supportability of the device is improved as FV is coaxial with the guidewire. FV was efficacious in B2-EUS-HGS, which shows promise for clinical application in the future.

Endoscopic ultrasound-guided portal vein coiling: troubleshooting interventional endoscopic ultrasonography.

Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HGS) is widely performed not only as an alternative to transpapillary biliary drainage, but also as primary drainage for malignant biliary obstruction. For anatomical reasons, this technique carries an unavoidable risk of mispuncturing intrahepatic vessels. We report a technique for troubleshooting EUS-guided portal vein coiling to prevent bleeding from the intrahepatic portal vein after mispuncture during interventional EUS. EUS-HGS was planned for a 59-year-old male patient with unresectable pancreatic cancer. The dilated bile duct (lumen diameter, 2.8 mm) was punctured with a 19-gauge needle, and a guidewire was inserted. After bougie dilation, the guidewire was found to be inside the intrahepatic portal vein. Embolizing coils were placed to prevent bleeding. Embolization coils were successfully inserted under stabilization of the catheter using a double-lumen cannula with a guidewire. Following these procedures, the patient was asymptomatic. Computed tomography performed the next day revealed no complications.

Utility of stent-in-stent technique in management of post-pancreatitis splenic abscess using forward-viewing echoendoscope.

Highlight Elshair and colleagues describe a novel technique which could be applied for drainage of any paragastric fluid collection, including pseudocyst and abscess. In comparison to the oblique-view echoendoscope, the forward-viewing echoendoscope allows concurrent stent-in-stent placement over the same axis. Double-pit stent deployment inside the metal stent prevents bleeding and metallic-stent kinking.

Outcomes of Endoscopic Ultrasound-Guided Biliary Drainage in Patients Undergoing Antithrombotic Therapy.

BACKGROUND/AIMS: The Japan Gastroenterological Endoscopy Society (JGES) has published guidelines for gastroenterological endoscopy in patients undergoing antithrombotic treatment. These guidelines classify endoscopic ultrasound-guided biliary drainage (EUS-BD) as a high-risk procedure. Nevertheless, the bleeding risk of EUS-BD in patients undergoing antithrombotic therapy is uncertain. Therefore, this study aimed to assess the bleeding risk in patients undergoing antithrombotic therapy. METHODS: This single-center retrospective study included 220 consecutive patients who underwent EUS-BD between January 2013 and December 2018. We managed the withdrawal and continuation of antithrombotic agents according to the JGES guidelines. We compared the bleeding event rates among patients who received and those who did not receive antithrombotic agents. RESULTS: A total of 18 patients (8.1%) received antithrombotic agents and 202 patients (91.8%) did not. Three patients experienced bleeding events, with an overall bleeding event rate of 1.3% (3/220): one patient was in the antithrombotic group (5.5%) and two patients were in the non-antithrombotic group (0.9%) (p=0.10). All cases were moderate. The sole thromboembolic event (0.4%) was a cerebral infarction in a patient in the non-antithrombotic group. CONCLUSION: The rate of EUS-BD-related bleeding events was low. Even in patients receiving antithrombotic therapy, the bleeding event rates were not significantly different from those in patients not receiving antithrombotic therapy.

Use of double biopsy forceps: A novel technique for safe removal of migrating stent after EUS-guided pancreatic drainage.

Highlight For migrating stent removal, Elshair and colleagues recommend using a double-channel scope and two biopsy forceps. The stent is fixed with one of the forceps and its proximal end is caught with the other while applying countertraction. The proximal end is cut, and the stent is safely removed through the duodenum.
