The endoscopic step-up drainage approach involving initial drainage followed by, if required, direct endoscopic necrosectomy (DEN) is the preferred management approach for symptomatic pancreatic necrotic collections. However, limited data suggests that immediate DEN during initial stent placement may hasten clinical recovery by quicker resolution of systemic inflammatory response. However, because of concerns about adverse effects, especially gastric perforation and bleeding, most endoscopists prefer delayed DEN. In this news and views, we discuss a recently published randomized controlled trial that compared upfront necrosectomy at the index intervention versus as a step-up for patients with infected necrotizing pancreatitis.

Aim and Objective Endoscopic ultrasound-guided liver biopsy (EUS-LB) is now increasingly being used across the globe as a method of liver tissue acquisition. This method is widely accepted by many professionals as it can overcome many shortcomings of percutaneous liver biopsy and transjugular liver biopsy. The aim of the study is to obtain the adequate and optimal biopsy rate associated with EUS-LB. Materials and Methods This is a retrospective observational study. Consecutive patients undergoing EUS-LB during the study period who were willing to consent were taken up for the study. Results Total 91 patients were taken up for the study. Median age of study population was 44 years out of which 39 patients were males and 52 were females (42.9 and 57.1%). Adequate biopsy rate (according to European Association for the Study of Liver Disease criteria) and optimal biopsy rate (according to American Association for the Study of Liver Diseases criteria) were 89 (81/91) and 60.4% (55/91), respectively. Rate of conclusive diagnosis was 95.6% (86/91). The commonest diagnosis encountered was nonalcoholic steatohepatitis) (23, 25.3%), followed by autoimmune hepatitis (17, 18.7%). Additional diagnostic information was obtained by endosonography during EUS-LB in 21 patients (23.1%). Gallstone disease was found in four (4.8%) patients, chronic calcific pancreatitis in two (1.9%) patients, significant abdominal lymphadenopathy defined as lymph node more than 1.5 cm in five (5.8%) patients, and esophageal or gastric varices in ten (10.6%) patients. One case of self-limiting biopsy site ooze was seen in EUS-LB and the patient was having cirrhosis. Conclusion This study showed a high diagnostic outcome and safety profile with EUS-LB technique. EUS-LB can achieve excellent histological yield when performed with optimal technique. Moreover, it is possible to obtain additional information during the procedure from diagnostic endosonography that is done as a part of EUS-LB.

Objectives The condition of air bubbles in the large intestine is an influential factor for good quality of colonoscopy. However, the correlative factors of severity of air bubbles during colonoscopy in the large intestine are not established. Therefore, this study aimed to elucidate the correlative factors influencing the severity of air bubbles in the large intestine. Materials and Methods A total of 314 examinees who underwent colonoscopy between August and September 2022 were enrolled (median age [range], 65 [18–88] years). Air bubbles were scored using the Colon Endoscopic Bubble Scale (CEBuS) and the clinical factors associated with the CEBuS scores, especially in the ileocecum, were analyzed. Results In this study, 39.8% (125/314) of examinees harbored severe air bubbles in the ileocecum. Multiple linear regression analysis revealed that the CEBuS scores in the ileocecum were positively associated with the interval time from completion of bowel preparation to intubation of the cecum (p = 0.0016) and a history of cholecystectomy (p = 0.0198). Logistic regression analysis between no, mild, and moderate air bubbles group (n = 189) and severe air bubbles group (n = 125) also showed that severity was positively associated with the interval time from completion of bowel preparation to intubation of the cecum (p = 0.0332) and a history of cholecystectomy (p = 0.0095). Conclusion Interval time and history of cholecystectomy were associated with severity of air bubbles in the large intestine after bowel preparation.

A 59-year-old man was hospitalized due to a complaint of intermittent upper abdominal distension that persisted over the duration of 2 years. Endoscopy revealed a fl at depressed (type 0-IIa þ IIc) and whitish lesion approximately 2.0 (cid:2) 2.5cm in size in the anterior wall of the antrum ( ► Fig. 1 ). Reddish spots were sparsely distributed in the mucosa of the lesion. No gastric mucosa atrophy was observed. Magnifying endoscopy with narrow-band imaging (NBI) showed a nice demarcation line between the lesion and the surrounding mucosa. The morphology of the lesion surface was irregular, with minimal residual glandular fossa, as well as damage and loss of the gastric pit structure, suggesting destruction of glands. The microvessels were bifurcated, sparse, and tortuous; “ tree like appearance ” of the abnormal vessels can be seen in the NBI ( ► Fig. 2 ). The 20-MHz mini-probe endoscopic ultrasound showed that all layers of the gastric wall were intact without abnormal echo ( ► Fig. 3 ).

Introduction Endoscopic submucosal dissection (ESD) is the first choice for superficial tumor resection. There is no report on whether the training effect is affected by limiting the operation time of each ESD operation. This study aimed to prospectively evaluate the efficiency of time-limited ESD training by using an ex vivo porcine stomach model. Methods ESD was performed in accordance with the standard procedure on ex vivo porcine stomach model. The time-limited group required each operation time to be controlled within 30 minutes, and the nonlimited group did not limit the operation time. The en bloc resection rate, surface area of the resected specimen, procedure speed, and perforation rate were compared in the two groups. Results Compared with the en bloc resection rate in the time-limited group, that in the nonlimited group was significantly higher in ESD-1 and ESD-2. In each ESD procedure, the median resection area in the nonlimited group was significantly larger than that in the time-limited group. The difference in median procedure speed between the two groups in ESD-1 to ESD-4 did not reach significance in the statistical analysis. The speed of ESD-5 in the time-limited group was significantly higher than that of the nonlimited group. The perforation rate of the time-limited group was similar to that of the nonlimited group. Conclusion Limiting the training time does not help the trainees to complete large resection of lesions and reduce the perforation rate, but it may help to improve the operation speed.

Abstract Colorectal cancer (CRC) is the third most common cancer in the world. Colonoscopy has contributed significantly to reduction of incidence and mortality of CRC. Integration of artificial intelligence (AI) into colonoscopy practice has addressed the various shortcomings of screening colonoscopies. AI-assisted colonoscopy will help in real-time recognition of type of polyp with probable histology. This will not only save time but will also help to mitigate human errors. Computer-aided detection and computer-aided characterization are two applications of AI, which are being studied extensively with a goal of improvement of polyp and adenoma detection rates. Several studies are being conducted across the globe, which either involve simple decision-making algorithms or complex patterns through neural networks, which imitate the human brain. Most data are collected retrospectively and the research is limited to single-center studies, which might have bias. Therefore, the future research on AI in colonoscopy should aim to develop more sophisticated convolutional neural network and deep learning models that will help to standardize the practice and ensure the same degree of accuracy with all the colonoscopies, irrespective of experience of performing endoscopists. In this review, we will take a closer look at the current state of AI and its integration into the field of colonoscopy.
