Objective To explore the efficiency and safety of endoscopic retrograde cholangiopancreatography (ERCP) in diagnosis and treatment of children with pancreaticobiliary diseases.Methods A retrospective study was conducted by data collection from 74 children with biliary and pancreatic diseases undergoing ERCP from January 2012 to December 2016 for observation of therapeutic efficacy and postoperative complications.Results A total of 96 ERCPs were performed on 74 patients.The success rate was 94.8％ (91/96) using 29 operating methods.The complication rate of pancreatitis was 10.8％ (8/74),as well as hyperamylasemia was 13.5％ (10/74) and stress hyperglycemia was 10.8％ (8/74).Conclusion The application of ERCP in children with biliary tract and pancreatic diseases is effective and safe.

Objective To explore the safety and efficacy of endoscopic retrograde cholangiopancreatography(ERCP)by using carbon dioxide for malignant biliary obstruction.Methods A total of 60 patients with malignant biliary obstruction, hospitalized from September 2008 to February 2010, were randomly divided into 3 groups to receive ERCP by using carbon dioxide, contrast agent or magnetic resonance cholangiopancreatography(MRCP)without any agent.The safety and efficacy of 3 contrast methods were compared.Results Successful stent or drainage tube insertion was achieved in all patients.Carbon dioxide was superior to contrast agent in terms of lowering postoperative infection rate(P ＜ 0.05), and it was also superior to MRCP for more effective drainage(P ＜ 0.05).There was no significant difference in occurrence of postoperative pancreatitis and hyperamylasemia between 3 groups.Conclusion Using carbon dioxide during ERCP, safe and effective, is superior to use of contrast agent in less leukocyte increase, and to MRCP in more adequate drainage in patients with malignant biliary obstruction.Furthermore, there is no more risk of pancreatitis and hyperamylasemia.

Objective To investigate the risk factors of cerebral hemorrhage in hypertensive intracerebral hemorrhage,and to provide a reference for clinical treatment.Methods The clinical data of 118 patients with hyper-tensive cerebral hemorrhage treated in our hospital were analyzed retrospectively.The clinical data of patients was col-lected and statistical analysis was carried out,and the risk factors of edema around the hematoma were analyzed by Logistic regression analysis.Results Multivariate non conditional logistic regression analysis showed that,the course of hypertensive cerebral hemorrhage of edema around the hematoma was the risk factor,the longer the duration,the more risk of hypertensive cerebral hemorrhage edema around the hematoma enlargement.There was no significant correlation between sex,age,bleeding site,broken into ventricles and the edema around the hematoma in hypertensive intracerebral hemorrhage.Diastolic blood pressure was a risk factor for the edema around the hematoma in hypertensive cerebral hemorrhage,the diastolic blood pressure control was not good,and the swelling of the edema around the hema-toma was increasing.While the systolic blood pressure,pulse pressure difference and hypertensive cerebral hemorrhage hematoma around the hematoma showed no obvious correlation.Use of amlodipine and vascular tension angiotensin converting enzyme inhibitor in hypertensive cerebral hemorrhage were the protective factors of edema around the hematoma, early application of amlodipine,vascular and nervous angiotensin converting enzyme inhibitor to control blood pressure helped to reduce hypertensive cerebral hemorrhage edema around the hematoma volume.Conclusion Amlodipine and vascular tension angiotensin converting enzyme inhibitors help to reduce hypertensive cerebral hemorrhage edema around the hematoma volume,while long course,poor control of diastolic blood pressure can promote hypertension cerebral hemorrhage edema around the hematoma volume increase.We should pay attention to the development of hypertensive cerebral hemorrhage and the control of diastolic blood pressure,as soon as possible to stabilize the patient's condition and avoid the expansion of the volume of edema around the hematoma.

Objectiye To evaluate the therapeutic efficacy and safety of (endoscopic sphincterotomy, EST) plus balloon dilation for difficult bile duct stones. Methods Patients with difficult common bile duct stones on endoscopic retrograde cholangiopancreatography (ERCP) from March 2008 to December 2009 were randomly divided into 2 groups to receive EST or EST plus balloon dilation ( EST + EPBD), respectively. The success rate of complete stone removal, number of endoscopic sessions, the rate of using mechanical lithotripsy and the complication rate related to the procedure were compared between the 2 groups. Results Compared with EST alone, EST plus balloon dilation resulted in similar outcomes in terms of overall successful stone removal rate (2/62 vs. 2/61 ) and early complication rate (4/62 vs. 6/61, P ＞0. 05). However,EST group needed more sessions ( EST 15/46 vs. EST + EPBD 5/57, P ＜0. 05) and use of mechanical lithotripsy to achieve complete removal of stones ( EST 12/61 vs. EST + EPBD 4/61, P ＜0. 05 ). Conclusion EST plus balloon dilation is as safe and effective as, but more convenient than EST, for endoscopic removal of common bile duct stones.

Objective To investigate the hemodynamic changes of protosystemic collaterals before and after endoscopic treatment in patients with gastroesophageal varices using 64-row multidetector computed tomograghy portal venography (MDCTPV) so as to evaluate the efficacy of endoscopic treatment in patients with or without para-esoghageal varices and with or without nonvarices portosystemic collaterals before treatment. Methods Twenty-six patients with gastroesophageal varices, who underwent endoscopic variceal ligation (EVL) for esophageal varices and endoscopic N-butyl-2-cyanoacrylate injection (EBC) for gastric varices between Jan.2007 and Dec. 2009, were enrolled. Sixty four-row MDCT was used to examine the changes of portosystemic collaterals 1 week before and 12 months after endoscopic treatment. The reconstructed images of portosystemic collaterals before and after endoscopic treatment were evaluated. Results Excellent quality of portosystemic collateral vessels on CTPV were obtained in all patients. The mean diameter of left gastric vein decreased from (6.7±1.9) mm to (5.0±1.9) mm after endoscopic treatment,with significant difference (P＜ 0.05). There was no significant difference in outcomes between patients with or without para-esoghageal varices (80% vs 72.7%, P＞0.05) and patients with or without non-varices portosystemic collaterals (82.4% vs 66.7% ,P＞0.05). Conclusions Sixty fourrow MDCTPV may provide important information for option of endoscopic treatment and prognosis.

ObjectiveTo explore the efficacy and safety of temporary placement of fully covered metal stent in the treatment of benign biliary strictures.MethodsFully covered metal stents were placed in 36 patients with benign biliary strictures.All patients were followed up every 1-2 months and the stents were removed when adequate biliary drainage was achieved.ResultsResolution of the benign biliary strictures was achieved in 28 of 36 patients (77.8％ ).All fully covered metal stents were removed successfully.Complications were observed in 3 patients (8.3％) after stent placement and in 1 (2.8％ ) after stent removal.ConclusionTemporary placement of fully covered metal stents for benign biliary strictures is safe and efficacious.Further investigation is required to longer follow-up.

Objective To evaluate the efficacy and safety of fluoroscopy guided frequency-doubled double-pulsed laser lithotripsy for removing difficult bile duct stones. Methods From March 2008 to December 2009, patients with difficult bile duct stones were divided into cholangioscopy guided group ( n = 21 )and fluoroscopy guided group ( n = 19) to receive corresponding treatments. The success rate of complete stone removal and the complication rate related to the procedure were compared between the two groups.Results There are no significant differences between 2 groups in regarding of either success rate of complete stone removal ( 19/21, 90. 5% in cholangioscopy guided group vs. 17/19, 89. 5% in fluoroscopy guided group, P ＞0. 05 ) or rate of procedure related complication (4/21, 19. 0% in cholangioscopy guided group vs. 3/19, 15. 8% in fluoroscopic guided group, P = 0. 559 ). Conclusion Frequency-doubled doublepulsed laser lithotripsy guided by cholangioscopy or fluoroscopy are both safe and effective.

Objective To evaluate a method named “one-step procedure”,i.e.,combined duode-noscopy,laparoscopy and choledochoscopy for choledocholithiasis accompanied with cholecystolithiasis.Meth-ods Fifty-three cases with gallbladder stones combined with common bile duct stones diagnosed from February 2012 to February 2014 were assigned to two groups,29 cases in “one-step procedure”group,who underwent duodenoscopy,laparoscopy and choledochoscopy in one operation,and 24 cases in the control group,who first-ly underwent endoscopic sphincterotomy to remove common bile duct stones,and then LC was performed after several days.The rate of complications related to the procedure,success rate of complete stone removal,length of hospital stay and hospitalization expenses were compared between the two groups.Results All 53 patients underwent the surgery and ERCP procedure successfully.There were no significant differences between the“one-step procedure”group and the control group in complication rates[3.4%(1 /29)VS 12.5%(3 /24),P =0.21],complete stone removal rates[96.6%(28 /29)VS 100.0%(24/24),P =0.37].Differences were sig-nificant in length of hospital stay (6.7 ±1.3d VS 10.9 ±1.6d,P <0.01 )and hospitalization expenses (15 724 ±1 613 yuan VS 19 829 ±2 433 yuan,P <0.05)between the “one-step procedure”group and the control group.Conclusion The “one-step procedure”,the combined duodenoscopy,laparoscopy and chole-dochoscopy,is safe,effective,and has smaller length of hospital stay and lower hospitalization expenses.
