ABSTRACT
Endoscopic transmural drainage is usually performed for symptomatic well-encapsulated walled-off necrosis (WON) that usually develops in the delayed phase (> 4 weeks after disease onset) of acute necrotising pancreatitis (ANP). Endoscopic drainage is usually not advocated in the early (< 4 weeks after disease onset) stage of illness because of the risk of complications due to an incompletely formed encapsulating wall and poor demarcation of viable from necrotic tissue. However, emerging data from expert tertiary care centres over the last few years shows that the early endoscopic transluminal drainage approach is effective and safe. The development of lumen-apposing metal stents and better accessories for endoscopic necrosectomy has fuelled the expansion of indications of endoscopic drainage of pancreatic necrosis. However, early endoscopic drainage is associated with higher rates of adverse events; therefore, careful patient selection is paramount. This article will review the current indications, techniques and outcomes of early endoscopic transluminal drainage in pancreatic necrotic collections.

INTRODUCTION: Risk of adverse effects and flare of inflammatory bowel disease (IBD) are frequently cited reasons for COVID-19 vaccine hesitancy. METHODS: Electronic databases were searched to identify studies reporting the use of COVID-19 vaccine in IBD. We selected studies reporting the incidence of various adverse effects (local or systemic) and flares of IBD after COVID-19 vaccination. The pooled incidence rates for various adverse effects, stratified for the dose and the type of vaccine (adenoviral or mRNA) were estimated. RESULTS: Nine studies (16 vaccination cohorts) were included. The pooled incidence rate of overall adverse events was 0.55 (95%CI, 0.45-0.64, I2= 95%). The pooled incidence rate of local adverse events was 0.64 (0.47-0.78, I2= 100%). The pooled incidence rates of fatigue, headache, myalgia, fever and chills were 0.30 (0.21-0.40, I2= 99%), 0.23 (0.17-0.30, I2= 99%), 0.18 (0.13-0.24, I2= 99%), 0.10 (0.06-0.17, I2= 98%) and 0.15 (0.06-0.3, I2= 86%), respectively. The pooled incidence rates of severe adverse events, adverse events requiring hospitalization and flares of IBD following COVID-19 vaccination were 0.02 (0.00-0.12, I2= 97%), 0.00 (0.00-0.01, I2= 27%) and 0.01 (0.01-0.03, I2= 45%), respectively. CONCLUSION: COVID-19 vaccination in patients with IBD appears to be safe with only mild adverse events. Flares of IBD and severe adverse events requiring hospitalization were infrequent.
