Endoscopic stent placement is a well-accepted and effective alternative treatment modality for complex and refractory esophageal strictures. Among the currently available types of stents, the partially covered self-expanding metal stent (SEMS) has a firm anchoring effect, preventing stent migration and ensuring effective covering of a narrowed segment. However, hyperplastic tissue reaction driv...
We report a case of aorto-bronchial ®stula 7 years after implantation of a self-expanding metal stent into the left main bronchus. The clinical presentation was characterised by left-sided chest pain, dyspnea and a single bout of haemoptysis. The ®stula was surgically managed by aortic resection and primary repair of the aorta, and patch repair of the left main bronchus over a Poly ̄ex covered b...
BACKGROUND Acute colonic obstruction because of advanced colonic malignancy is a surgical emergency. AIM To compare the clinical outcomes and cost-effectiveness of endoscopic self-expanding metal stent (SEMS) vs. surgery for emergent management of acute malignant colonic obstruction in patients with metastatic colorectal cancer over a 6-month period. METHODS Decision analysis was used to ca...
Figure 1 The endoscope is inserted through the distal end of Several techniques for managing migrated and misplaced self-expanding esophageal metal stents have been described.1--5 However, most of these techniques apply only when there is distal stent dislodgment. When there is proximal stent migration or misplacement, and unless there is a lasso at the distal flange, trying to reposition the s...

Background and study aims We report our experience in endoscopic ultrasound-guided gallbladder drainage performed emergently in 4 prohibitive surgical risk patients with concurrent coagulopathy or on anticoagulant therapy using an electrocautery enhanced lumen apposing self expanding metal stent (LA-SEMS).
Walled-off pancreatic necrosis and a pancreatic abscess are the most severe complications of acute pancreatitis. Surgery in such critically ill patients is often associated with significant morbidity and mortality within the first few weeks after the onset of symptoms. Minimal invasive approaches with high success and low mortality rates are therefore of considerable interest. Endoscopic therap...
Background: Self-expanding Y metal stent insertion is a safe and effective palliative method for malignant lesions involving the lower trachea, tracheal carina, main-stem bronchi. However, length degree of airway stenosis in different patients tend to vary, which leads call customized that could achieve better treatment effect.
