Chronic pancreatitis (CP), a progressive inflammatory disease that results in irreversible pancreatic damage, is often complicated by ductal strictures and debilitating pain. Fully covered self-expandable metal stents (FCSEMS) have emerged as significant innovations in the endoscopic management of refractory pancreatic duct strictures. This review synthesizes recent evidence highlighting the benefits and limitations of FCSEMS, such as superior patency, reduced need for reinterventions, and effective symptom relief compared to traditional plastic stents, alongside risks, such as stent migration and de novo strictures. A comparison with plastic stents and an algorithm for pancreatic duct stricture management are provided. Regional variations in clinical guidelines from the United States, Europe, Japan, and Korea reflect diverse approaches to integrating FCSEMS into practice. Emerging innovations in stent technology are promising for improving CP management outcomes.
Background /Aims: Endoscopic resection is the first-line treatment for rectal neuroendocrine tumors (NETs) measuring <1 cm and those between 1 and 2 cm in size. However, conventional endoscopic resection cannot achieve complete resection in all cases. We aimed to analyze clinical outcomes of precut endoscopic mucosal resection (EMR-P) used for the management of rectal NET.
Methods EMR-P was used to treat rectal NET in 72 patients at a single tertiary center between 2011 and 2015. Both, circumferential precutting and EMR were performed with the same snare device in all patients. Demographics, procedural details, and histopathological features were reviewed for all cases.
Results Mean size of the tumor measured endoscopically was 6.8±2.8 mm. En bloc and complete resection was achieved in 71 (98.6%) and 67 patients (93.1%), respectively. The mean time required for resection was 9.0±5.6 min. Immediate and delayed bleeding developed in six (8.3%) and 4 patients (5.6%), respectively. Immediate bleeding observed during EMR-P was associated with the risk of delayed bleeding.
Conclusions Both, the en bloc and complete resection rates of EMR-P in the treatment of rectal NETs using the same snare for precutting and EMR were noted to be high. The procedure was short and safe. EMR-P may be a good treatment choice for the management of rectal NETs.
