INTRODUCTIONThere are limited data on the use of endosonography-guided fine-needle aspiration (EUS-FNA) to determine the nature of left adrenal lesions. We described our experience in performing EUS-FNA of left adrenal lesions.
CLINICAL PICTUREDuring a 20-week period, data on consecutive patients who underwent EUS with or without EUS-FNA were prospectively captured. Patients with a left adrenal mass and who underwent EUS-FNA formed our study population.
TREATMENTEUS-FNA.
OUTCOMEA total of 119 consecutive patients underwent diagnostic EUS +/- FNA, during which the left adrenal gland was routinely examined. Twelve of these patients underwent EUS as part of lung cancer staging and among these 12 lung cancer patients, 2 had left adrenal masses detected by computed tomography (CT). EUS detected left adrenal nodules in 2 other patients which were not visualised by CT. The overall prevalence of a left adrenal mass was 3.4%; in the subgroup with confirmed lung cancer, the prevalence was 33.3%. All 4 patients were male, with a mean age of 76.3 years (range, 67 to 87). The mean size of the left adrenal lesion was 30.4 mm (range, 9 to 84.8). EUS-FNA of the left adrenal lesions was performed under Doppler guidance. The mean number of needle passes was 2 (range, 1 to 4). A cellular aspirate was obtained in all patients. No procedural complications occurred. Metastatic non-small cell lung cancer was diagnosed in 2 patients, including a lesion missed on CT. For the other 2 cases, EUS-FNA revealed benign adrenal cells.
CONCLUSIONSEUS-FNA appears safe and useful for the evaluation of left adrenal masses.

The development of deep learning systems in artificial intelligence (AI) has enabled advances in endoscopy, and AI-aided colonoscopy has recently been ushered into clinical practice as a clinical decision-support tool. This has enabled real-time AI-aided detection of polyps with a higher sensitivity than the average endoscopist, and evidence to support its use has been promising thus far. This review article provides a summary of currently published data relating to AI-aided colonoscopy, discusses current clinical applications, and introduces ongoing research directions. We also explore endoscopists’ perceptions and attitudes toward the use of this technology, and discuss factors influencing its uptake in clinical practice.

INTRODUCTIONEndoscopic transenteric stenting is the standard treatment for pseudocysts, but it may be inadequate for treating infected collections with solid debris. Surgical necrosectomy results in significant morbidity. Direct endoscopic necrosectomy (DEN), a minimally invasive treatment, may be a viable option. This study examined the efficacy and safety of DEN for the treatment of infected walled-off pancreatic necrosis and infected pseudocysts with solid debris.
METHODSThis study was a retrospective analysis of data collected from a prospective database of patients who underwent DEN in the presence of infected walled-off pancreatic necrosis or infected pseudocysts with solid debris from April 2007 to October 2011. DEN was performed as a staged procedure. Endoscopic ultrasonography-guided transgastric stenting was performed during the first session for initial drainage and to establish endoscopic access to the infected collection. In the second session, the drainage tract was dilated endoscopically to allow transgastric passage of an endoscope for endoscopic necrosectomy. Outcome data included technical success, clinical success and complication rates.
RESULTSEight patients with infected walled-off pancreatic necrosis or infected pseudocysts with solid debris (mean size 12.5 cm; range 7.8-17.2 cm) underwent DEN. Underlying aetiologies included severe acute pancreatitis (n = 6) and post-pancreatic surgery (n = 2). DEN was technically successful in all patients. Clinical resolution was achieved in seven patients. One patient with recurrent collection opted for surgery instead of repeat endotherapy. No procedural complications were encountered.
CONCLUSIONDEN is a safe and effective minimally invasive treatment for infected walled-off pancreatic necrosis and infected pseudocysts.

Background/Aims:
Despite the disproportionally high prevalence rates of hepatitis C virus (HCV) amongst the incarcerated population, eradication remains challenging due to logistic and financial barriers. Although treatment prioritization based on disease severity is commonly practiced, the efficacy of such approach remained uncertain. We aimed to compare the impact of unrestricted access to direct-acting antiviral (DAA) among incarcerated HCV-infected patients in Singapore.
Methods:
In this retrospective study, we reviewed all incarcerated HCV-infected patients treated in our hospital during the restricted DAA era (2013–2018) and unrestricted DAA access era (2019). Study outcomes included the rate of sustained virological response (SVR), treatment completion and treatment default. Subgroup analysis was performed based on the presence of liver cirrhosis, HCV genotype and HCV treatment types.
Results:
A total of 1,001 HCV patients was followed-up for 1,489 person-year. They were predominantly male (93%) with genotype-3 HCV infection (71%), and 38% were cirrhotic. The overall SVR during the restricted DAA access era and unrestricted DAA access era were 92.1% and 99.1%, respectively. Unrestricted access to DAA exponentially improved the treatment access among HCV-infected patients by 460%, resulting in a higher SVR rate (99% vs. 92%, P=0.003), higher treatment completion rate (99% vs. 93%, P<0.001) and lower treatment default rate (1% vs. 9%, P<0.001).
Conclusion
In this large cohort of incarcerated HCV-infected patients, we demonstrated that unrestricted access to DAA is an impactful strategy to allow rapid treatment up-scale in HCV micro-elimination.

Liver fibrosis is a slow, insidious process involving accumulation of extracellular matrix protein in the liver. The stage of liver fibrosis in chronic liver disease (CLD) determines overall morbidity and mortality; the higher the stage, the worse the prognosis. Noninvasive composite scores can be used to determine whether patients with CLD have significant or advanced fibrosis. Patients with low composite scores can be safely followed up in primary care with periodic reassessment. Those with higher scores should be referred to a specialist. As the epidemic of diabetes mellitus, obesity and non-alcoholic fatty liver diseases is rising, CLD is becoming more prevalent. Easy-to-use fibrosis assessment composite scores can identify patients with minimal or advanced fibrosis, and should be an integral part of decision-making. Patients with cirrhosis, high composite scores, chronic hepatitis B with elevated alanine aminotransferase and aspartate aminotransferase, or deranged liver panel of uncertain aetiology should be referred to a specialist.
