ABSTRACT
Objective@#To study the prognostic factors of delayed gastric emptying(DGE) after pancreaticoduodenectomy(PD) and construct a prognostic predictive model for clinical application.@*Methods@#Clinic data of 401 consecutive patients who underwent PD between January 2012 and July 2016 in the First Affiliated Hospital of Harbin Medical University were retrospectively collected and analyzed. The patients were randomly selected to modeling group(n=299) and validation group(n=102) at a ratio of 3∶1. The data of modeling group were subjected to univariate and multivariate analysis for prognostic factors and to construct a prognostic predictive model of DGE after PD. The data of validation group were applied to test the prognostic predictive model.@*Results@#DGE after PD occurred in 35 of 299 patients(11.7%) in the modeling group. The multivariate analysis of the modeling group showed that upper abdominal operation history(χ2=6.533, P=0.011), diabetes mellitus(χ2=17.872, P=0.000), preoperative hemoglobin <90 g/L(χ2=14.608, P=0.000) and pylorus-preserving pancreaticoduodenectomy(PPPD)(χ2=8.811, P=0.003) were associated with DGE after PD independently. A prognostic predictive model of DGE after PD was constructed based on these factors and successfully tested. The area under the receiver operating characteristic(ROC) curve was 0.761(95%CI: 0.666-0.856) of the modeling group and 0.750(95% CI: 0.577-0.923) of the validation group.@*Conclusions@#Upper abdominal operation history, diabetes mellitus, preoperative hemoglobin<90 g/L and PPPD are associated with DGE after PD independently. The preoperative assessment of a patient′s prognostic for DGE after PD is feasible. The model is a valid tool to take precautions against DGE after PD.
ABSTRACT
Objective To study the delayed gastric emptying for patients underwent pylorus-preserving pancreaticoduodenectomy and standard Whipple procedure.Methods Clinical data of 401 consecutive patients who underwent standard Whipple procedure/pylorus-preserving pancreaticoduodenectomy between January 2012 and July 2016 in the First Affiliated Hospital of Harbin Medical University were retrospectively collected and analyzed.Using the independent-samples t test,x2 test or Fisher's exact test,Mann-Whitney test and other statistical methods to compare the postoperative complications between pylorus-preserving pancreaticoduodenectomy and standard Whipple procedure group.Results Compare with standard Whipple procedure group,delayed gastric emptying after pylorus-preserving pancreaticoduodenectomy occurred in 8 of 35 patients (22.9％),obviously higher than it after standard Whipple procedure occurred in 40 of 366 patients (10.9％) (P =0.038).Other postoperative complications were not significantly different (P ≥ 0.05).Each level of delayed gastric emptying after pyloruspreserving pancreaticoduodenectomy and standard Whipple procedure were not significantly different (P ≥ 0.05),but the average recovery time of delayed gastric emptying after pylorus-preserving pancreaticoduodenectomy (12.13 ± 3.09) d was obviously shorter than it after standard Whipple procedure (17.28 ± 9.63) d (P =0.009).Conclusions Pylorus-preserving pancreaticoduodenectomy increases the risk of delayed gastric emptying,but it does not increase severity delayed gastric emnptying by each level.The recovery time of delayed gastric after pyloruspreserving pancreaticoduodenectomy is shorter.
ABSTRACT
Objective To investigate enteral or parenteral nutrition therapy effects in the aspects of patients' postoperative nutrition status,incidence of complications and health economics indicators of pancreatic head carcinoma or periampullary carcinoma patients after pancreaticoduodenectomy.Methods The clinical data of patients underwent PD in the First Affiliated Hospital of Harbin Medical University from January 2010 to August 2015 were collected.According to different postoperative nutrition therapy,patients were divided into parenteral followed enteral nutrition group (treatment group) and parenteral nutrition group (control group).Observed indicators such as postoperative nutrition status,liver and kidney function,incidence of complications,length and total cost of hospitalization were assessed.Results This study enrolled 207 cases in treatment group and 92 cases in control group.There was no significant difference in preoperative NRS scores,surgical procedures,pathology and other preoperative clinical indicators (P ＞ 0.05).Postoperative bilirubin reduction(△TB1.10) in treatment group versus control group had significant difference (P ＜ 0.05).Compared with postoperative Day 1,the prealbumin level of Day 7 and Day 10 in treatment group recovered rapidly than control group(△PA7.1,△PA10-1),however the differernce was not significant (P ＞ 0.05).Postoperative complications (pancreatic fistula,post-pancreatectomy hemorrhage,inna-abdominal infection,delayed gastric emptying) in treatment group and control group had no significant difference (P ＞ 0.05).The average and median hospitalization in treatment group [(28 ± 11) d,26 d] versus control group [(32 ± 18) d,29 d] had significant difference (P ＜ 0.05).The total cost of hospitalization in treatment group and control group were not significantly different(P ＞ 0.05).Conclusions This study indicated that postoperative parenteral followed enteral nutrition therapy could significantly enhance the recovery of liver function,shorten the length of hospitalization in patients after PD.Moreover,parenteral followed enteral nutrition therapy did not significantly increase the postoperative complications.
ABSTRACT
Objective To evaluate the efficacy of epidural anesthesia combined with different doses ropivacaine and sufentanil for stepwise labor analgesia in latent phase.Methods Two hundred and ten ASA Ⅰ or Ⅱ primiparas with a singleton and vertex presentation at full term in our hospital from February 201 5 to April 201 5 were randomized into seven groups (n =30 each):0.125% ropiva-caine with 0.5 μg/ml sufentanil (group 1);0.075% ropivacaine with 0.5 μg/ml sufentanil (cervical dilatation dural block between groups at each time.The latent period of group 2 and 3 were shorter than that in group 1 (P <0.05)and that of group 5 and 6 were shorter than that in group 4 (P <0.05);the ac-tive phase of group 4 were longer than that in group 1 (P <0.05 ).The postpartum hemorrhage of group 2 and 3 were less than that in group 1 (P <0.05),the postpartum hemorrhage of group 5,6 and 7 were more than that in group 2 (P <0.05)and group 3 (P <0.05).The motor nerve block of group 2 and 3 were slightly less than that in group 1 (P <0.05)and the motor nerve block of group 5,6 and 7 were slightly less than that in group 4 (P <0.05).There was no difference of the postpar-tum adverse reactions of maternal and Apgar score in the neonates.Conclusion The dosage of 0.075% or 0.1% ropivacaine with 0.5 μg/ml sufentanil (cervical dilatation < 3 cm),0.125% ropiv-acaine with 0.5 μg/ml sufentanil (cervical dilatation ≥ 3 cm),while producing the exact analgesic effect,hardly interferes with the 1abor process,the amount of postpartum hemorrhage and the lower limb activity,thus they have no significant effect on the safety of the maternal and the infant.
ABSTRACT
Objective To investigate the effects and value of enhance recovery after surgery (ERAS) application in patients with hepatocellular carcinoma underwent liver resection.Methods One hundred and seventy-two patients with hepatocellular carcinoma underwent liver resection in the first affiliated hospital of Harbin medical university from June 2013 to June 2015,ERAS group (92 cases) and control group (80 cases) were retrospectively studied.Laboratory indicators (ALT,AST,TBIL,ALB,PA,lymphocyte count),postoperative complications,postoperative hospitalization days and total hospitalization expenses were compared between two groups.Results For postoperative liver functional indicators (ALT,AST,TBIL),ERAS group Day 1 and Day 7 were respectively (216.3±141.7) U/Land (70.1 ±29.4) U/L,(184.0±155.8) U/Land (39.1 ±17.5) U/L,(22.4± 8.7) μmol/L and (20.0 ± 7.5) μmol/L,control group were respectively (304.5 ± 226.2) U/L and (83.9 ± 48.5) U/L,(294.1 273.0) U/L and (49.2 ±33.8) U/L,(26.9 ±15.6) μmol/L and (24.6 ± 10.8) μmol/L,the difference between two groups was statistically significant (F =9.33,9.84,9.26,P ＜ 0.05).For postoperative nutritional indicators (ALB,PA),ERAS group Day 7 were respectively (35.3 ± 4.4) g/Land (136.3 ±34.1) mg/L,control group were respectively (33.6 ±4.2) g/L and (108.0 ± 32.5) mg/L,the difference was statistically significant (F =4.97,4.54,P ＜ 0.05).For postoperative immune indicators (lymphocyte count),ERAS group Day 1 and Day 7 were respectively (0.9 ±0.3) × 109/L and (1.5 ± O.5) × 109/L,control group were respectively (0.7 ± 0.3) × 109/L and (1.3 ± 0.5) × 109/L,the difference was statistically significant (F =7.37,P ＜ 0.05).For postoperative complications (hemorrhage,bile fistula,hepatic dysfunction,infection) were no statistically significant differences (P ＞ 0.05),however,ascites had statistically significant difference (x2 =7.609,P ＜ 0.05).Off bed time,postoperative exhaust time,postoperative hospitalization time and total hospitalization expense of ERAS group were respectively (1.7 ± 0.5) days,(2.3 ± 0.6) days,(9.8 ± 2.3) days,(4.6 ± O.9) × 104 RMB,control group were respectively (3.0 ± 0.7) days,(3.4 ± 0.8) days,(17.6 ± 5.8) days,(6.3 ± 2.1) × 104 RMB,the difference was statistically significant (t =13.032,10.937,11.371,7.118,P ＜ 0.05).Conclusions Application of ERAS in patients with HCC underwent liver resection is safe and effective.ERAS effectively reduce stress reaction of patients,promote the recovery of liver function,improve the postoperative immune and nutrition status,shorter postoperative hospitalization time,and reduce the total cost of hospitalization.
