Aim: To review the current status of the novel technique of endoscopic necrosectomy in the management of pancreatic necrosis after acute pancreatitis.
Methods: Studies were identified by searching Medline, PubMed and Embase databases for articles from January 1990 to December 2009 using the keywords "acute pancreatitis", "pancreatic necrosis" and "endoscopy". Additional papers were identified by a manual search of the references from the key articles. Case series of fewer than five patients and case reports were excluded.
Results: Indications, techniques and outcomes of endoscopic necrosectomy were analysed. There were no randomised controlled trials identified. Ten case series were included in this analysis. There were a total of more than 1,100 endoscopic necrosectomy procedures in 260 patients with pancreatic necrosis. One hundred fifty-five were proven to be infected necrosis on culture. The overall mortality rate was 5%. The mean procedure-related morbidity rate was 27%. The rate of complete resolution of pancreatic necrosis with the endoscopic method alone was 76%.
Conclusions: Endoscopic necrosectomy is a safe and effective treatment option in selected patients with pancreatic necrosis after acute pancreatitis. Future studies will be required to further define the selection criteria and the techniques for the endoscopic procedure.

Background: Open surgical debridement was the main treatment option for infected pancreatic necrosis (IPN). However, it was associated with significant trauma, leading to a higher mortality rate. With the development of minimally invasive surgery, the step-up treatment principle centered around minimally invasive intervention, significantly reducing the incidence of complications and mortality rates among IPN patients.

Background And Aims: Endoscopic ultrasound (EUS)-guided transmural drainage with on-demand endoscopic necrosectomy (EN) is increasingly utilized to manage walled-off necrosis (WON). It has not been fully elucidated how EN and its timing are correlated with treatment outcomes compared to the drainage-based approach.
Methods: Within a multi-institutional cohort of 423 patients with pancreatic fluid collections including 227 patients with WON, we identified 153 patients who received the step-up treatment following the initial EUS-guided drainage of symptomatic WON, including 102 EN patients and 51 non-EN (drainage) patients.

Introduction: Endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs) has variable outcomes according to the type of lumen-apposing metal stent (LAMS) used. We aimed to perform a systematic review and meta-analysis of the available data.
Methods: Online databases, including EMBASE, PubMed, and SCOPUS, were searched from inception to 30 January 2024.

Background: The acute and chronic pancreatitis (CP) can lead to severe complications like walled-off necrosis, large symptomatic pseudocyst or multiorgan failure. The treatment of these complications is multivariate and can differ from conservative, symptomatic treatment or minimal-invasive, endoscopic transgastral stenting to transgastral necrosectomy.
Objectives: This study aims to analyse the clinical course for patients that develop local complications of severe pancreatitis.

Article Synopsis
- The study compares two methods of endoscopic necrosectomy—percutaneous endoscopic necrosectomy (PEN) and endoscopic transmural necrosectomy (ETN)—for treating necrotizing pancreatitis (NP), focusing on their safety and efficacy.
- A total of 280 adult NP patients were analyzed, revealing that while those who underwent PEN experienced higher rates of complications like sepsis and respiratory failure, there were no significant differences in overall outcomes, such as clinical success or postoperative complications, between the two methods.
- The findings suggest that PEN may be a suitable option for managing sicker patients with NP, as it shows similar efficacy and safety compared to ETN in a real-world setting.
