RESUMO
Objective To investigate the effect of X-ray assisted nasal catheter extractor on nose biliary oronasal conversion. Methods A total of 892 patients,receiving endoscopic nasal biliary drainage in Affiliated Zhongshan Hospital of Dalian University from January 2014 to December 2015, were randomly divided into experiment group and control group. X-ray assisted nasal catheter extractor was used in the experiment group,and guide wire was used in the control group. The mean extracting number and operation time, the total success rate, one-time success rate, response to stimulation and the incidence of complications were compared between the two groups. Results There were 457 cases in the experiment group. The mean extracting number was 1.08±0.32,the mean operation time was 1.07±0.29 min,the total success rate was 100.00%(457/457)and one-time success rate was 93.65%(428/457). The stimulation degree score was 1.27±0.50 with 348 cases of mild response,96 cases of moderate response and 13 cases of severe response. The rate of adverse reaction was 15.54%(71/457)with 50 cases of nausea, 18 cases of vomiting and 3 cases of mucosal bleeding. There were 435 cases in control group. The mean extracting number was 1.68±0.61,the mean operation time was 1.75±0.53 min, the total success rate was 75.63%(329/435)and one-time success rate was 38.16%(166/435). The stimulation degree score was 1.59 ±0.62 with 210 cases of mild response,194 cases of moderate response and 31 cases of severe response. The rate of adverse reaction was 35.86%(156/435)with 87 cases of nausea,36 cases of vomiting,27 cases of mucosal bleeding,and 6 cases of nasal duct prolapsed for vomiting. There were significant differences in the mean extracting number, mean operation time, stimulation degree score and the adverse reaction rate between the two groups(all P<0.001). The total success rate and one-time success rate in the experiment group were higher than those in the control group(all P<0.001).Conclusion X-ray assisted nasal catheter extractor can improve the success rate of operation,shorten the operation time,reduce the stimulation degree and the rate of adverse reactions in nose biliary oronasal conversion.
RESUMO
Objective To investigate the role of endoscopic sphincterotomy(EST)and endoscopic nasobiliary drainage(ENBD)in the treatment of non-biliary severe acute pancreatitis(SAP).Methods 73 patients were randomly divided into the endoscopic treatment group(35 cases)and control group(38 cases).The patients in control group received non-surgical treatment.EST plus ENBD were performed in patients in the endoscopic treatment group 72h within hospitalization.Serum levels of amylase before EST and 1d,3 d,7 d after EST were measured;the ease of pain and recovery of bowel function were documented;the mortality rate,complication rate,surgery rote and hospital stay were also observed.Results The successful cannulation rate in the EST group was 94.3%(33/35),and there was no procedure related complication.Serum levels of amylase before EST and 1d,3 d,7 d after EST were(1376±131)U/L,(675±49)U/L,(238±49)U/L,(75±13)U/L,the serum levels of amylase before EST and 1d after EST in the EST group were not significantly different from those in the control group,but the corresponding values at 3 d,7 d were significantly lower than those in the control group(P＜0.01).The apparent effective rate and total effective rate of pain relief was 37.1%and 48.6%.which was significantly higher than those in the control group (26.3%and 28.9%,P＜0.05).There was no mortality in both groups.The complication rate in the EST group within 30 d was 14.3%,which was signiilcanfly higher than that in the control group(44.7%,P＜0.01).The gurgery rate in EST group was 2.86%,which was significantly lower than that in the control group (21.1%,P＜0.05).The hospital stay in EST group was(27.6±4.0)d,which was significantly shorter than that in the control group[(41.7±5.9)d,P＜0.05].Conclusions EST and ENBD treatment for non-biliary SAP was superior to non-surgical treatment within 72 h of symptom onset with excellent safety and feasibility profile.
RESUMO
Objective:To discuss the clinical use of endoscopic Sphincterotomy(EST)and endoscopic nosalbiliary drainage(ENBD) in the treatment of severe acute pancreatitis.Methods:77 patients were divided into the endoscopic treatment group and contol group.EST plus ENBD were performed in patients of the endoscopic treatment group 24h after hospitalization.The control group were treated with the combination of treatment.Blood was drawn in each group the day and 48h following hospitalization for amylase measurement.The time of bellyache relief.the morbidity rate and hospital stay were also observed.Results:48h after hospitalization amylase measurement was significiantly lower in endoscopic treatment group 982?mol/L?24?mol/L than that in control group(1576?mol/L?31?mol/L,P
