RESUMEN
Objective To investigate the effects of simple topical anesthesia and intravenous general anesthesia on the occurrence of pancreatitis after ERCP.Methods 400 Patients who underwent ERCP due to pancreaticobiliary duct disease in our hospital from January 2021 to March 2023 were selected and divided into two groups:Simple topical anesthesia group and intravenous general anesthesia group,200 cases in each group.The levels of venous pancreatic amylase and abdominal symptoms and signs were recorded in the two groups before operation and 3 h and 24 h after operation.The observation results were hyperamylaseemia and postoperative pancreatitis at 3 h and 24 h after operation.Results The incidence of postoperative pancreatitis after ERCP was higher in the superficial anesthesia group than in the intravenous general anesthesia group(7.5％and 2.0％,respectively;P＜0.05),there was statistical significance;The level of serum pancreatic amylase(198±216)U/L in intravenous general anesthesia group was significantly lower than that in superficial anesthesia group(379±327)U/L at 3h after surgery(P＜0.05).The level of serum pancreatic amylase(129±98)U/L in intravenous general anesthesia group was lower than that in superficial anesthesia group(187±156)at 24h after surgery(P＜0.05).The incidence of hyperamylasemia was 15.5％(31/200 cases)in the 3h postoperative intravenous general anesthesia group,lower than that in the simple surface anesthesia group(34.5％)(69/200 cases),and 5.5％(11/200 cases)in the 24h postoperative intravenous general anesthesia group,lower than that in the simple surface anesthesia group(19.0％)(38/200 cases)(P＜0.05).Conclusion Compared with simple surface anesthesia,intravenous general anesthesia can reduce the level of serum amylase after ERCP,and can reduce the occurrence of pancreatitis after ERCP.
RESUMEN
Objective:To investigate the risk factors for common bile duct calculi recurrence and application value of its prediction model after endoscopic retrograde cholangiopancreato-graphy (ERCP) .Methods:The retrospective cohort study was conducted. The clinicopatholo-gical data of 506 patients with common bile duct calculi who were admitted to the First Hospital of Lanzhou University from January 2015 to December 2017 for ERCP routine treatment were collected. There were 251 males and 255 females, aged (59±15)years. Patients received ERCP for common bile duct calculi. Observation indicators: (1) clinicopathological data of patients with common bile duct calculi; (2) risk factors for common bile duct calculi recurrence after ERCP; (3) establishment of prediction model for common bile duct calculi recurrence after ERCP. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate and multivariate analysis were conducted using the COX proportional hazard model. The prediction model for the recurrence of common bile duct stones after ERCP was established according to the coefficient of regression equation. The receiver operating characteristic curve(ROC) was drawed for efficiency evaluation with area under curve (AUC). Results:(1) Clinicopathological data of patients with common bile duct calculi: 104 of 506 patients with common bile duct calculi had recurrence and 402 had no recurrence. There were significant differences in the age, hyperlipidemia, common bile duct diameter, distal bile duct stricture, the number of calculi, gallbladder status, history of biliary tract surgery, endoscopic spinecterotomy, postoperative drainage mode between patients with and without recurrence ( Z=?2.844, χ2=6.243, Z=?2.897, χ2=11.631, 4.617, 16.589, 18.679, 2.070, 50.274, P<0.05). (2) Risk factors for common bile duct calculi recurrence after ERCP: Results of univariate analysis showed that age, time of first attack, hyperlipidemia, common bile duct diameter, distal bile duct stricture, the number of calculi, the maximum calculi diameter, gallbladder status, history of biliary tract surgery and postoperative biliary drainage mode were related factors for common bile duct calculi recurrence after ERCP ( hazard ratio=1.656, 2.179, 1.712, 1.657, 2.497, 1.509, 1.971, 2.635, 3.649,95% confidence interval as 1.113?2.463, 1.135?4.184, 1.122?2.644, 1.030?2.663, 1.501?4.154, 1.025?2.220, 1.122?3.464, 1.645?4.221, 1.575?8.456, P<0.05). Results of multivariate analysis showed that time of first attack <30 days, hyperlipidemia, distal bile duct stricture, history of biliary tract surgery and postoperative biliary drainage mode as cholangiopancreatic stent were independent risk factors for common bile duct calculi recurrence after ERCP ( hazard ratio=2.332, 1.676, 2.088, 2.566, 3.712, 95% confidence interval as 1.089?4.998, 1.060?2.649, 1.189?3.668, 1.456?4.521, 1.296?10.635, P<0.05). (3) Establishment of prediction model for common bile duct calculi recurrence after ERCP: based on multivariate analysis, indicators including time of first attack <30 days, hyperlipidemia, distal bile duct stricture, history of biliary tract surgery and postoperative biliary drainage mode as cholangiopancreatic stent were included into the coefficient of regression equation, and the prediction model for common bile duct calculi recurrence after ERCP was established: ln[(λ(t))/(λ 0(t))]=0.847×time of first attack+0.516×hyperlipidemia+0.736×distal bile duct stricture+0.942×history of biliary tract surgery+1.312×cholangiopancreatic stent. The perfor-mance evaluation showed that the AUC of ROC of prediction model was 0.757 (95% confidence interval as 0.713?0.811, P<0.05), and the optimal cut-off value was 1.41, the sensitivity and specificity were 69.2% and 72.9% respectively. Conclusions:The time of first attack <30 days, hyperlipidemia, distal bile duct stricture, history of biliary tract surgery and postoperative biliary drainage mode as cholangiopancreatic stent are independent risk factors for common bile duct calculi recurrence after ERCP. Patients with evaluation score >1.41 in prediction model were at high risk for common bile duct calculi recurrence after ERCP.
RESUMEN
Objective:To investigate the clinical efficacy of early pancreatic duct stenting in the treatment of acute pancreatitis.Methods:The retrospective and descriptive study was conducted. The clinical data of 201 patients with acute pancreatitis who were admitted to General Hospital of Ningxia Medical University from October 2011 to December 2017 were collected. There were 106 males and 95 females, aged from 18 to 90 years, with a median age of 62 years. Of 201 patients, there were 178 cases with moderate severe acute pancreatitis and 23 cases with serious severe acute pancreatitis. Patients were treated with pancreatic duct stenting within 48 hours after admission. Observation indicators: (1) treatment; (2) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect recurrence of acute pancreatitis after surgery up to June 2019. Measurement data with normal distribution were represented by Mean± SD, and the independent sample t test was used for comparison between groups, and the matched samples t test was used for comparison between before and after. Measurement data with skewed distribution were represented by M( P25 ,P75) or M(range), and the Mann-Whitney U test was used for comparison between groups, and the Wilcoxon signed rank sum test was used for comparison between before and after. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test . Results:(1) Treatment: 201 patients received pancreatic duct stenting successfully, 63 of which were detected pancreatic obstruction with white-floc. The interval time from admission to surgery , operation time, time for initial oral intake, duration of hospital stay and hospital expenses of 201 patients were 10 hours(4 hours,22 hours), (35±15)minutes, 3 days(2 days,5 days), 6 days(5 days,10 days) and 3.8×10 4 yuan (3.0×10 4 yuan,4.9×10 4 yuan). Of 201 patients, 22 patients were transferred to intensive care unit, including 1 case with serious severe underwent inhospital death and 1 case with moderate severe and 7 cases with serious severe underwent auto-discharge from hospital. There were 25 cases with local complications, including 17 cases with pancreatic infectious necrosis, 7 cases with pancreatic walled-off necrosis and 1 case with spleen infarction. All 25 patients were cured after surgical inter-vention or conservative treatment. Further analysis showed that cases being transferred to intensive care unit, cases undergoing surgical treatment, the time for initial oral intake, duration of hospital stay and cases undergoing auto-discharge from hospital were 6, 11, 3 days(2 days,5 days), 6 days(5 days,10 days) and 1 for the 178 moderate severe cases, versus 16, 5, 7 days(4 days,9 days), 9 days (7 days,17 days) and 7 for the 23 serious severe cases, showing significant differences ( χ2=91.561, 6.730, Z=6.485, 5.463, χ2=47.561, P<0.05). The white blood cell count, serum amylase indexes and chronic health evaluation Ⅱ score of 201 patients were (14±6)×10 9/L, 928 U/L(411 U/L,1 588 U/L), 9±5 before admission, versus (10±4)×10 9/L, 132 U/L(72 U/L,275 U/L), 6±4 at 48 hours after admission, respectively, showing significant differences ( t=12.219, Z=11.639, t=16.016, P<0.05). (2) Follow-up: of 201 patients, 153 cases were followed up for 40 months (27 months,55 months). During the follow-up, 32 of the 153 cases had recurrence of acute pancreatitis. Conclusion:Early pancreatic duct stenting is safe and feasible in the treatment of acute pancreatitis.
