3 mm), 1.8 m long, compatible with 19-gauge needles in endoscopic ultrasound-guided fine needle (19 G EchoTip). The catheter has 2 ring electrodes 8 mm apart with the distal electrode 5 mm from the leading edge, providing local coagulative necrosis over a 2.5-cm length Energy was delivered by an RFA generator (1500 RF generator; RITA Medical Systems Inc, Fremont, Calif) delivering electrical energy at 400 kHz at 7 to 10 W for 2 minutes, with a rest period of 1 minute Epigenetics inhibitor before moving the

catheter. (C) Results: The pain had complete relief and the patient gave up their morphine-based medication 2 weeks after the procedure. Conclusion: Endoscopic Ultrasound-guided celiac plexus block by radiofrequency ablation seems to be a safe and effective method for short-term pain management in patients with inoperable pancreatic cancer.

Methods: Data of 23 patients with ectopic pancreas diagnosed by EUS and confirmed by pathological examination were reviewed. The feature of EUS image and diagnostic accuracy were retrospectively analyzed. Results: Out of 23 patients, 22 (95.6%)were pathologieally diagnosed as having ectopie pancreas. All ectopie pancreases presented as MCE公司 protruding lesions, in which 16 were located at gastric antrum, 1 in gastric body and 6 in duodenum. Under EUS, The Sirolimus price lesion involved muscularis mucosae in 4 cases. Submucosa in 17. no other complications occurred. There Was one relapse during the 6 months of followed – up. Conclusion: EUS

is valuable and safe for the diagnosis of ectopic panere. as in upper gastro inte- stinal tract. Key Word(s): 1. EUS; 2.

EC has made it possible to diagnose living tumor cells in vivo and to obtain ultra-magnification pathological images simply by applying the scope to the target mucosa during an endoscopic examination.
