Self-expanding metal stents are a useful therapy to palliate malignant and benign luminal gastrointestinal obstruction. Self-expanding metal stents has been widely reported for colonic, esophageal, and gastric obstruction. However, endoscopic delivery and placement to the small bowel is more challenging and difficult. This case illustrates the usefulness and technical advantages of the balloon-overtube and enteroscopy technique for the palliative treatment of neoplastic stenosis affecting the small intestine.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has evolved to become an indispensable tool for tissue acquisition. While the overall diagnostic accuracy of EUS-FNA is greater than 90% for lung cancer staging, it is lower for pancreatic mass lesions. Several factors such as location of the tumor, disease characteristics and procedural techniques determine the outcomes of EUS-FNA. In this review we evaluate the various technical factors that are keys to attaining optimal procedural outcomes.
