EUS in the diagnosis and treatment of digestive diseases progress Safe and effective method of cancer caused by abdominal pain. 79% to 88% of patients with abdominal pain lasting remission painkiller dose of 82% to 91% of patients and even less - oEUS - of CPN combined with radioactive iodine seed implantation is more effective to alleviate pancreatic cancer caused by abdominal pain and can last longer. Changhai Hospital, Department of Gastroenterology, 33 cases of pancreatic cancer and peritoneal metastasis of cancer patients using ultrasound Endoscopic ultrasound - guided celiac ganglion injection of bupivacaine and ethanol injection therapy. Results: All patients underwent the operation is successful, the success rate of 100%. Did not occur after acute pancreatitis, pancreatic leakage, bleeding, perforation, and intra - abdominal infection and other serious complications. Postoperative 12h pain scores were significantly lower rate of 100% pain relief; 24h after pain relief rate of 98%, 90% pain relief in postoperative 72h, postoperative the 1w pain response rate 88%. With or without systemic chemotherapy were divided into two groups according to preoperative chemotherapy group after 12h, 24h, 72h and 1W of pain relief rates were 100%, 100%, 98% and 98%, without chemotherapy after surgery 12h, 24h, At 72h, the pain relief 1W and 1nl, were 100%, 98%, 95%, 90% and 7 (]% ; statistical analysis, the preoperative chemotherapy group 72h after operation and 1W of pain relief and without chemotherapy There were significant. 3.3.8EUS guide cyst stomach catheter drainage of pancreatic: The main advantage of the Act as: (1) accurately determine the distance of the cyst wall and the stomach, duodenum wall asked if there larger blood vessels, to select the optimal puncture site; (2) clearly shows that the whole process of puncture and catheter, to avoid puncture needle through the wall; (3) can be observed that the cysts shrink and disappear, which determine the treatment. 4EU $ the future of the 16th International EUS academic conference the (EUS2008) main [ReportandC. mmunicati.
