ABSTRACT
Objective To discuss how to preven wrong absorption of pancreatic pseudocyst using guided transmural drainage under endoscopic ultrasonography.Methods Retrospectively analyzed the clinical data of patients with pancreatic pseudocysts underwent operations of Endoscopic ultrasonography guided transmural drainage.Results 16 cases of pancreatic pseudocysts were finished with guided transmural drainage under endoscopic ultrasonography using needling to place bypass grafting with successful rate 100.0% of guided transmural drainage by needling. After needling, 2 cased happened regurgitation which led to wrongly absorbed, rate of occurrence is 12.5%. Generally, pancreatic pseudocysts of 16 cases disappeared completely with cure rate 100.0%. From above, stents were pulled out by endoscope in 3 cases while stents were removed voluntarily in another 13 cases.Conclusion Dorsal elevated position, detailed operation and esophageal annular tubes can effectively prevent wrong absorption of guided transmural drainage under endoscopic ultrasonography of pancreatic pseudocysts.
ABSTRACT
Objective To investigate the therapeutic value of duodenoscopy in the treatment of acute obstructive suppurative cholangitis without X-ray guided. Methods Clinical data of acute obstructive suppurative cholangitis were collected continuously in our hospital which can be used to analyze the safety and efficacy of duodenoscopy in treatment without X-ray guided. Results 146 patients were successfully treated with ERCP in bile duct cannulation, the successful rate was 93.6 % (146/156), all the patients' bilirubin decreased, the successful rate of endoscopic treatment was 93.6% (146/156), while minor pancreatitis, hyperamylasemia, cholangitis, duodenal perforation and other complications occurred in 18 patients, the incidence rate was 11.5% (18/156). 13 patients infected with obstructive suppurative cholangtis were successfully treated with duodenoscopy without X-ray guided, and the successful rate in bile duct cannulation was 86.7%(13/15), bilirubin decreased in 12 cases, the successful rate in endoscopic treatment was 80.0%(12/15), 3 patients suffered from complications, the incidence rate was 20.0% (3/15). Conclusions The bile duct cannulation technique without X-ray guided has progressed, it can be applied to cure several patients with biliary obstruction, especially in AOSC patients, and pregnant patients, and patients who are not suitable for the X-ray radiation.
