    Acute Pancreatitis (AP) poses a significant healthcare burden globally. While most cases present with a mild course, approximately one-fifth progress to severe forms characterized by severe pancreatitis and systemic complications, leading to a mortality rate of up to 40%. Effective management of severe acute pancreatitis necessitates a multidisciplinary approach involving gastroenterologists, interventional radiologists, intensive care teams, and surgeons. The advances in treatment modalities, including early hydration, nutrition, and pain control, have led to a decrease in the morbidity and long-term complications associated with severe acute pancreatitis down to 20%. In this review, we focus on the management challenges and outcomes associated with the difficult condition of severe acute pancreatitis.

    Guidelines recommend using percutaneous endoscopic gastrostomy (PEG) for dysphagia after 2 weeks of stroke onset. We aimed to study the impact of PEG timing on outcomes in patients with ischemic stroke.

    More info
    Early-onset colorectal cancer (CRC) is a growing global health concern, especially in the Asia-Pacific region. However, comprehensive research on this topic from the region is lacking. Our study aims to investigate trends in early-onset CRC in Asia over 10 years, filling this research gap.
