  • Barrett's esophagus is associated with an increased risk of adenocarcinoma. Thorough screening during endoscopic surveillance is crucial to improve patient prognosis. Detecting and characterizing dysplastic or neoplastic Barrett's esophagus during routine endoscopy are challenging, even for expert endoscopists. Artificial intelligence-based clinical decision support systems have been developed to provide additional assistance to physicians performing diagnostic and therapeutic gastrointestinal endoscopy. In this article, we review the current role of artificial intelligence in the management of Barrett's esophagus and elaborate on potential artificial intelligence in the future.

  • Endoscopic resection (ER) is widely utilized as a minimally invasive treatment for upper gastrointestinal tumors; however, complications could occur during and after the procedure. Post-ER mucosal defect leads to delayed perforation and bleeding; therefore, endoscopic closure methods (endoscopic hand-suturing, the endoloop and endoclip closure method, and over-the-scope clip method) and tissue shielding methods (polyglycolic acid sheets and fibrin glue) are developed to prevent these complications. During duodenal ER, complete closure of the mucosal defect significantly reduces delayed bleeding and should be performed. An extensive mucosal defect that comprises three-quarters of the circumference in the esophagus, gastric antrum, or cardia is a significant risk factor for post-ER stricture. Steroid therapy is considered the first-line option for the prevention of esophageal stricture, but its efficacy for gastric stricture remains unclear. Methods for the prevention and management of ER-related complications in the esophagus, stomach, and duodenum differ according to the organ; therefore, endoscopists should be familiar with ways of preventing and managing organ-specific complications.

  • With incessant advances in information technology and its implications in all domains of our lives, artificial intelligence (AI) has emerged as a requirement for improved machine performance. This brings forth the query of how this can benefit endoscopists and improve both diagnostic and therapeutic endoscopy in each part of the gastrointestinal tract. Additionally, it also raises the question of the recent benefits and clinical usefulness of this new technology in daily endoscopic practice. There are two main categories of AI systems: computer-assisted detection (CADe) for lesion detection and computer-assisted diagnosis (CADx) for optical biopsy and lesion characterization. Quality assurance is the next step in the complete monitoring of high-quality colonoscopies. In all cases, computer-aided endoscopy is used, as the overall results rely on the physician. Video capsule endoscopy is a unique example in which a computer operates a device, stores multiple images, and performs an accurate diagnosis. While there are many expectations, we need to standardize and assess various software packages. It is important for healthcare providers to support this new development and make its use an obligation in daily clinical practice. In summary, AI represents a breakthrough in digestive endoscopy. Screening for gastric and colonic cancer detection should be improved, particularly outside expert centers. Prospective and multicenter trials are mandatory before introducing new software into clinical practice.

  • Purpose: The purpose of this study was to investigate job stress and job satisfaction among nurses in gastrointestinal endoscopy units, and factors related to their job stress and job satisfaction. Methods: The study participants were 153 nurses working in gastrointestinal endoscopy units at eleven general hospitals. Job stress and job satisfaction were measured using nurses's job stress scale and the index of work satisfaction respectively. Results: The average job stress was 3.67 (range 1~5) and job satisfaction was 2.90 (range 1~5). Gastrointestinal endoscopy unit nurses, who were full time worker, having more than 7 years of clinical experiences, having higher incomes, having high subjective work-intensity, and having an intention to change their working units, showed greater job stresses than those of the others. There were significant differences in job satisfaction according to subjective health status, the types of employment, subjective work-intensity, subjective aptitude, intention to change working units, major nursing tasks, and the numbers of major nursing tasks. Also, the subjects's job stress showed a negative correlation with job satisfaction. Conclusion: Findings suggest that management strategies should be developed to increase job satisfaction focusing on general and job characteristics associated with job stress.

  • Purpose: This study aimed to identify the effects of musculoskeletal symptoms and burden on presenteeism among nurses in a gastrointestinal endoscopy unit. Methods: This was an observational cross-sectional study. Data were collected through self-reported questionnaires administered to 140 nurses working in the gastrointestinal endoscopy unit of a hospital located in Busan metropolitan city. Results: The body part with the most musculoskeletal symptoms was the back (73.2%), and the most common musculoskeletal burden work was "when you have to stand or maintain the same posture for a long time in a lead apron protection clothes." The factors most related to work impairment were working hours, musculoskeletal symptoms, and musculoskeletal burden, with an explanatory power of 63.3%. Factors affecting perceived productivity were working hours and musculoskeletal symptoms, with an explanatory power of 29.2 %. Conclusion: To reduce work impairment and increase the perceived productivity of nurses in gastrointestinal endoscopy units, various programs and improved working environments are needed that can improve musculoskeletal symptoms and reduce musculoskeletal burden.

  • Small bowel tumors have been difficult to diagnose because of low incidence and absence of specific symptoms. There are no efficient and accurate tests available for diagnosis. Capsule endoscopy is an efficient diagnostic tool for small bowel disease and obscure gastrointestinal bleeding. We diagnosed two cases of small bowel gastrointestinal stromal tumor (GIST) diagnosed by capsule endoscopy that were treated by surgery. A 68 year old male presented with abdominal pain. The capsule endoscopy showed fungating ulcer mass at the jejunum. A 55 year female presented with melena. The capsule endoscopy showed an intraluminal protruding mass with a superficial ulcer at the jejunum. Two cases were diagnosed with GIST after surgery. We report these two case diagnosed by capsule endoscopy and review the medical literature.

  • Upper gastrointestinal postsurgical leaks are life-threatening conditions with high mortality rates and are one of the most feared complications of surgery. Leaks are challenging to manage and often require radiological, endoscopic, or surgical intervention. Steady advancements in interventional endoscopy in recent decades have allowed the development of new endoscopic devices and techniques that provide a more effective and minimally invasive therapeutic option compared to surgery. Since there is no consensus regarding the most appropriate therapeutic approach for managing postsurgical leaks, this review aimed to summarize the best available current data. Our discussion specifically focuses on leak diagnosis, treatment aims, comparative endoscopic technique outcomes, and combined multimodality approach efficacy.

  • In general, gastroesophageal reflux disease (GERD) is diagnosed clinically based on typical symptoms and/or response to proton pump inhibitor treatment. Upper gastrointestinal endoscopy is reserved for patients presenting with alarm symptoms, such as dysphagia, odynophagia, significant weight loss, gastrointestinal bleeding, or anorexia; those who meet the criteria for Barrett's esophagus screening; those who report a lack or partial response to proton pump inhibitor treatment; and those with prior endoscopic or surgical anti-reflux interventions. Newer endoscopic techniques are primarily used to increase diagnostic yield and provide an alternative to medical or surgical treatment for GERD. The available endoscopic modalities for the diagnosis of GERD include conventional endoscopy with white-light imaging, high-resolution and high-magnification endoscopy, chromoendoscopy, image-enhanced endoscopy (narrow-band imaging, I- SCAN, flexible spectral imaging color enhancement, blue laser imaging, and linked color imaging), and confocal laser endomicroscopy. Endoscopic techniques for treating GERD include esophageal radiofrequency energy delivery/Stretta procedure, transoral incisionless fundoplication, and endoscopic full-thickness plication. Other novel techniques include anti-reflux mucosectomy, peroral endoscopic cardiac constriction, endoscopic submucosal dissection, and endoscopic band ligation. Currently, many of the new endoscopic techniques are not widely available, and their use is limited to centers of excellence.
