All gastrointestinal endoscopic procedures have a high risk of aerosol contamination of the coronavirus disease 2019 (COVID-19) to endoscopists, nurses, and healthcare assistants. Given the current pandemic situation of COVID-19, the Japan Gastroenterological Endoscopy Society issued the recommendation for gastrointestinal (GI) endoscopy based on the status of COVID-19 as of April 9, 2020, in Japan: (i) indications for GI endoscopy in the pandemic of COVID-19; (ii) practical protective equipment for medical personnel depending on the risk for COVID-19; (iii) preprocedural management, such as pharyngeal local anesthesia using lidocaine spray which has a potential to generate the aerosols; (iv) ideal settings of the endoscopy room including the numbers of the staff and the patients; (v) postprocedural management, such as undressing and follow-up of the patients, as well as the involved staff, were documented to fit the practical scenarios in GI endoscopy, with the available data in Japan and the world. We believe that certain measures will prevent further spread of COVID-19.

Some situations may require endoscopy during the COVID-19 (Coronavirus Disease 2019) pandemic. Here, we describe the necessary precautions in the form of clinical questions and answers (Q&A) regarding the safe deployment of gastrointestinal endoscopy in such situations while protecting endoscopy staff and patients from infection. Non-urgent endoscopy should be postponed. ⋯ When a patient who undergoes endoscopy is later found to have COVID-19, the members of staff involved are considered exposed to the virus and must not work for at least 14 days if their PPE is considered insufficient. When PPE resources are limited, some equipment may be used continuously throughout a shift as long as it is not contaminated. Details of the aforementioned protective measures are described.

Review Meta Analysis Comparative Study
Comparison of propofol monotherapy and propofol combination therapy for sedation during gastrointestinal endoscopy: A systematic review and meta-analysis.
Previous randomized controlled trials have reported conflicting findings comparing propofol combination therapy (PCT) with propofol monotherapy (PMT) for sedation of patients undergoing gastrointestinal endoscopy. Therefore, a systematic review was carried out to compare the efficacy and safety of PCT and PMT in such patients. ⋯ PCT showed comparable efficacy and safety to PMT with respect to respiratory complications, hypotension and arrhythmia, recovery time, procedure duration, patient satisfaction, and doctor satisfaction. However, the average dose of propofol used was higher in PMT.

Endoscopic ultrasound (EUS)-guided drainage is now firmly established as the best option for drainage of walled-off pancreatic fluid collections (PFC). It has high clinical efficacy, similar to surgical and percutaneous approaches, but with lower morbidity and costs. ⋯ Traditionally, double pigtail plastic stents (PS) were used for transmural drainage, but, recently, fully covered self-expandable metallic stents (FCSEMS) customized for PFC drainage have become available and are increasingly used, especially in the management of WON, because the larger-diameter stent facilitates drainage and insertion of an endoscope into the WON cavity for DEN. The present review will discuss the evidence for EUS-guided drainage and DEN, the technical problems involved, and the roles of PS and FCSEMS in PFC drainage.

Several gastrointestinal societies strongly recommend colonoscopy surveillance after endoscopic and surgical resection of colorectal neoplasms. Common denominators to these recommendations include: high-quality baseline colonoscopy before inclusion in a surveillance program; risk stratification based on clinicopathological profiles to guide surveillance intervals; and endoscopist responsibility for providing surveillance advice. ⋯ In this review, we examine key factors for quality of post-polypectomy surveillance practice, in particular bowel preparation, endoscopic findings at baseline examination and adherence to surveillance recommendations. Frequently asked questions by the practising endoscopist are addressed.
