Helicobacter pylori (H. pylori) is an important pathogen in the stomach which can cause chronic inflammation, predisposing patients to peptic ulcer disease. It is also a class 1 human carcinogen, increasing the risk of gastric carcinoma. Eradication of H. pylori has been shown to be effective in the prevention of peptic ulcer disease as well as gastric carcinoma. Singapore is an intermediate-risk area for gastric cancer, and the seroprevalence of H. pylori infection is 31 percent. Testing for H. pylori consists of non-invasive tests such as H. pylori serology, stool antigen assay, and the urea breath test, as well as invasive tests requiring oesophago-gastro-duodenoscopy (OGD) and biopsies for the rapid urease test, histology, and cultures. Stool antigen assay represents a more accurate non-invasive outpatient test for H. pylori at slightly increased cost in the primary care setting, as positive H. pylori serology does not necessarily imply active infection. Triple therapy remains an effective first-line eradication treatment in Singapore from studies of H. pylori resistance locally. Treatment failures should be retreated with quadruple therapy or other strategies such as concomitant therapy, hybrid therapy and sequential therapy.

Endoscopic retrograde cholangiopancreatography (ERCP) plays a crucial role in the management of pancreaticobiliary disorders. Although the ERCP technique has been refined over the past five decades, it remains one of the endoscopic procedures with the highest rate of complications. Risk factors for ERCP-related complications are broadly classified into patient-, procedure-, and operator-related risk factors. Although non-modifiable, patient-related risk factors allow for the closer monitoring and instatement of preventive measures. Post-ERCP pancreatitis is the most common complication of ERCP. Risk reduction strategies include intravenous hydration, rectal nonsteroidal anti-inflammatory drugs, and pancreatic stent placement in selected patients. Perforation is associated with significant morbidity and mortality, and prompt recognition and treatment of ERCP-related perforations are key to ensuring good clinical outcomes. Endoscopy plays an expanding role in the treatment of perforations. Specific management strategies depend on the location of the perforation and the patient’s clinical status. The risk of post-ERCP bleeding can be attenuated by preprocedural optimization and adoption of intra-procedural techniques. Endoscopic measures are the mainstay of management for post-ERCP bleeding. Escalation to angioembolization or surgery may be required for refractory bleeding. Post-ERCP cholangitis can be reduced with antibiotic prophylaxis in high risk patients. Bile culture-directed therapy plays an important role in antimicrobial treatment.

Background/Aims:
The coronavirus disease of 2019 (COVID-19) pandemic has impacted the training of medical trainees internationally. The aim of this study was to assess the global impact of COVID-19 on endoscopy training from the perspective of endoscopy trainers and to identify strategies implemented to mitigate the impact on trainee education.
Methods:
Teaching faculty of gastroenterology (GI) training programs globally were invited to complete a 36-question web-based survey to report the characteristics of their training programs and the impact of COVID-19 on various aspects of endoscopy training, including what factors decisions were based on.
Results:
The survey response rate was 52.6% (305 out of 580 individuals); 92.8% reported a negative impact on endoscopy training, with suspension of elective procedures (77.1%) being the most detrimental factor. Geographic variations were noted, with European programs reporting the lowest percentage of trainee participation in procedures. A higher proportion of trainees in the Americas were allowed to continue performing procedures, and trainers from the Americas reported receiving the greatest support for endoscopy teaching.
Conclusions
This study demonstrated that the COVID-19 pandemic has had a significant negative impact on GI endoscopy training internationally, as reported by endoscopy trainers. Focus-optimizing endoscopy training and assessment of competencies are necessary to ensure adequate endoscopy training.

Gastric cancer (GC) has a good prognosis, if detected at an early stage. The intestinal subtype of GC follows a stepwise progression to carcinoma, which is treatable with early detection and intervention using high-quality endoscopy. Premalignant lesions and gastric epithelial polyps are commonly encountered in clinical practice. Surveillance of patients with premalignant gastric lesions may aid in early diagnosis of GC, and thus improve chances of survival. An expert professional workgroup was formed to summarise the current evidence and provide recommendations on the management of patients with gastric premalignant lesions in Singapore. Twenty-five recommendations were made to address screening and surveillance, strategies for detection and management of gastric premalignant lesions, management of gastric epithelial polyps, and pathological reporting of gastric premalignant lesions.

Antithrombotic agents, including antiplatelet agents and anticoagulants, are widely used in Korea because of the increasing incidence of cardiocerebrovascular disease and the aging population. The management of patients using antithrombotic agents during endoscopic procedures is an important clinical challenge. The clinical practice guidelines for this issue, developed by the Korean Society of Gastrointestinal Endoscopy, were published in 2020. However, new evidence on the use of dual antiplatelet therapy and direct anticoagulant management has emerged, and revised guidelines have been issued in the United States and Europe. Accordingly, the previous guidelines were revised. Cardiologists were part of the group that developed the guideline, and the recommendations went through a consensus-reaching process among international experts. This guideline presents 14 recommendations made based on the Grading of Recommendations, Assessment, Development, and Evaluation methodology and was reviewed by multidisciplinary experts. These guidelines provide useful information that can assist endoscopists in the management of patients receiving antithrombotic agents who require diagnostic and elective therapeutic endoscopy. It will be revised as necessary to cover changes in technology, evidence, or other aspects of clinical practice.
