ABSTRACT

Objective:To investigate the risk factors for delayed gastric emptying (DGE) following pancreaticoduodenectomy (PD).Methods:Clinical data of 385 patients who underwent PD in Changhai Hospital of Navy Medical University from January 2017 to November 2017 were retrospectively analyzed, including 235 men and 150 women. According to the definition of DGE by the International Study Group of Pancreatic Surgery (ISGPS), patients were divided into-clinically irrelevant DGE (non CR-DGE) group and clinically relevant DGE(CR-DGE) group. Univariate analysis and multivariate logistic analysis were used to identify the risk factors of CR-DGE after PD.Results:Of the 385 patients, 78 cases (20.3%) developed DGE. There were 35 cases of CR-DGE (9.1%). In the multivariate analysis, BMI( OR=1.117, 95% CI1.006-1.240, P=0.038), preoperative serum albumin( OR=0.902, 95% CI 0.832-0.977, P=0.012), the main pancreatic duct diameter (MPD)≤3 mm( OR=2.397, 95% CI 1.016-5.653, P=0.046), soft texture of pancreas( OR=2.834, 95% CI 1.093-7.350, P=0.032), clinically relevant postoperative pancreatic fistula (CR-POPF)( OR=4.498, 95% CI 1.768-11.441, P=0.002) were independent risk factors for CR-DGE after PD. Conclusions:High BMI, low preoperative serum albumin, MPD ≤3 mm, soft texture of pancreas and CR-POPF after surgery were independent risk factors for CR-DGE, and early clinical interventions should be performed.

ABSTRACT

Objective@#To examine the prognostic value of four important driver gene mutations in patients with radical resection of pancreatic cancer.@*Methods@#The clinical data and follow-up data of pancreatic cancer patients undergoing radical pancreatectomy and targeted sequencing from January 2016 to March 2018 at Department of Hepato-Biliary-Pancreatic Surgery, Changhai Hospital were retrospectively analyzed.There were 159 males and 88 females,aged of (60.8±8.7)years(range:33-83 years) and preoperative CA19-9 of (492.4±496.6)kU/L(range: 2-1 200 kU/L). One hundred and fifty nine cases of tumors were located in the head and 88 cases in the body and tail of the pancreas. After univariate analysis of clinical pathological factors (including gender, age, preoperative CA19-9, tumor location, tumor differentiation, pathological T and N stage, Micr. perineural invasion, Micr. lympho-vascular invasion, resection margin), the variable whose P<0.1 was included in COX regression model with four important driver gene mutations to find which mutation was related to prognosis independently. The number of gene mutations and KRAS subgroups were analyzed by Kaplan-Meier curve.@*Results@#Among 247 patients,the number of KRAS,TP53, SMAD4 and CDKN2A mutations was 212 cases(85.8%), 160 cases(64.8%), 66 cases(26.7%) and 44 cases(17.8%),respectively.KRAS mutation was correlated with the tumor differentiation and pathological T stage (χ2=24.570/6.690, P=0.000/0.035), TP53 mutation was correlated with the tumor differentiation and the resected margin(χ2=5.500/4.620, P=0.019/0.032), and CDKN2A mutation was correlated with gender(χ2=16.574, P=0.000).COX regression model analysis showed that only KRAS mutation was an independent risk factor for disease free survival and overall survival(HR=1.776, 95%CI: 1.079-2.923, P=0.024; HR=1.923, 95%CI: 1.016-3.639, P=0.045); KRASG12D mutation was associated with shorter OS(P=0.007).@*Conclusion@#KRAS and its subgroup KRASG12D mutation can be used as a prognostic index for patients with radical resection of pancreatic cancer.

ABSTRACT

Objective@#To compare the clinical therapeutic effects of arterial first approach pancreaticoduodenectomy(AFA-PD) with standard approach pancreaticoduodenectomy(SPD) in the treatment of borderline resectable pancreatic cancer (BRPC).@*Methods@#A retrospective analysis of the clinical data of 113 cases of pancreatic cancer patients from January 2014 to August 2015 at Department of Hepato-Biliary-Pancreatic Surgery, Changhai Hospital, the Second Military Medical University, including 43 cases in AFA-PD group and 70 cases in SPD group.Every patient had gone high-resolusion computed tomography before the surgery, when BRPC was definitely diagnosed by both experienced radiologist and pancreatic surgeon.There were 24 males and 19 females in the AFA-PD group, with average age of (61.6±10.2)years.And in the SPD group, there were 47 males and 23 females, with average age of (62.7±9.4)years.@*Results@#The operation time was (210.7±31.5)minutes in AFA-PD group, (187.9±27.4)minutes in SPD group, and peroperative bleeding volume was (1 007.1±566.3)ml in AFA-PD group, (700.0±390.0)ml in the other group.Those two indicators of AFA-PD group, compared with SPD group, were relatively higher, the difference was statistically significant(all P<0.01). And with regard to postoperative diarrhea(9.3% vs.5.7%), postoperative 1, 3 days of white blood cells(postoperative 1 day: (13.3±1.1)×109/L vs.(12.4±2.4)×109/L; postoperative 3 days: (12.7±1.6)×109/L vs.(11.7±2.5)×109/L), postoperative 1, 3, 5 days of peritoneal drainage fluid volume(postoperative 1 day: (184±42)ml vs.(156±54)ml; postoperative 3 days: (155±48)ml vs.(133±35)ml; postoperative 5 days: (66±20)ml vs.(47±31)ml), the differences between the two groups were statistically significant (all P<0.05). One patient in the SPD group was treated with unplanned secondary surgery for postoperative intraperitoneal hemorrhage, and the patient was cured and discharged.There was no death in the two groups within 30 days after surgical operation and no patient with positive gastric margin, duodenal margin, or anterior margin.The resection rate of superiormesenteric artery(SMA) margin R0 in AFA-PD group was higher than that in SPD group (P=0.019). The two groups were followed up for 14 to 30 months.As for AFA-PD group, the average survival time, progression free survival time and median survival time was respectively (20.4±1.2)months, (21.5±1.4)months and 20 months.There were 3 cases(7.0%) with local recurrence and 8 cases(18.6%) with liver metastasis or distant metastasis.In the SPD group, the average survival time, progression free survival time and median survival time was (17.1±1.1)months, (16.4±1.3)months and 16 months, respectively.There were 13 cases(18.6%) with local recurrence and 25 cases(35.7%) with liver metastasis or distant metastasis.As a result, the AFA-PD group had longer survival time(P=0.001)and progression free survival time(P=0.002). However, the lower local recurrence and distant metastasis rate in AFA-PD group did not reach statistical standard (P>0.05).@*Conclusion@#The arterial first approach pancreaticoduodenectomy is safe and effective in the treatment of borderline resectable pancreatic cancer, which can improve the resection rate of SMA margin R0, and prolong patient survival time.

ABSTRACT

Objective To investigate the utility of plasma procalcitonin (PCT) as an early predictor for postoperative complications in patients who underwent elective pancreaticoduodenectomy (PD).Methods Clinical data of 87 patients who underwent elective PD in Changhai Hospital from March.1, 2016 to Dec.31, 2016 were collected.The general data, postoperative recovery, serum PCT level and white blood cell (WBC) count before, 1 d, 3 d and 5 d after PD were recorded.ROC curve was drawn and AUC was calculated to determine the cutoff value, sensitivity and specificity.Patients were divided into complication group (n=42) and noncomplication group (n=45) based on the occurrence of post-operative complications, and the comparisons between the two groups were performed.Results There were no significant differences on the age, gender, diabetes, obstructive jaundice, laboratory tests including PCT, operative time, blood loss volume during surgery and tumor type between the two groups, which were comparable.Complication group had longer hospitalization than noncomplication group (24 d vs 15 d,P0.05), but the plasma PCT level in patients with pancreatic fistula and peritoneal infection on 3 d and 5 d after PD was significantly higher than those in noncomplication group, and the difference was statistically significant (all P<0.05).The combination of plasma PCT and WBC on 3 d and 5 d after PD was superior to PCT or WBC alone in predicting pancreatic fistula (sensitivity 88.9%, 72.7%;specificity 68.5%, 78.2%) and abdominal infection (sensitivity 100%, 100%;specificity 45.9%, 44.4%).Conclusions Plasma PCT could predict the occurrence of abdominal infection and pancreatic fistula after PD.The combination of PCT and WBC might be more valuable in predicting abdominal infection and pancreatic fistula.

ABSTRACT

To study and analyze the causes of chylous leakage after pancreaticoduodenectomy. We retrospectively analyzed 381 patients who underwent pancreaticoduodenectomy [including pylorus-preserving pancreaticoduodenectomy] in Shanghai Chang Hai Hospital Affiliated to the Second Military Medical University, Shanghai, China between January 2010 and December 2012. We also studied the relationship between postoperative chylous leakage and age, gender, surgical approach, and the tumor nature. The chylous leak was placed in 23 patients and the incidence of chylous leakage in patients was 0.6%. There was no significant difference in gender, age and tumor pathological pattern between the chylous leakage group and non-chylous leakage group. The incidence of chylous leakage in patients with N1 grade cancer was significantly higher than that in patients with N0 grade cancer [p=0.001]. The incidence of chylous leakage in patients suffering R0 resection was significantly higher than that in patients suffering non-R0 resection [p=0.008]. All patients were successfully treated conservatively. The incidence of chylous leakage was 0.6% and the chylous leakage was closely linked with the tumor's grade malignancy and the range of radical resection

ABSTRACT

Objective: To compare post-orthotopic liver transplantation(OLT) survival rates between patients with recurrent HCC after partial hepatectomy and those with de novo OLT for HCC, and to screen for the risk factors associated with post-OLT mortality. Methods: From July 2003 to August 2005, 77 consecutive HCC patients underwent OLT, including 15 patients with recurrent HCC after partial hepatectomy for tumor resection (the rescue OLT group) and 62 patients with de novo OLT for HCC (the de novo OLT group); the post-operation survival rates were compared between the 2 groups. Thirty-three demographic, clinical, histological, laboratory and intra- and post-operative variables were analyzed. Cox proportional hazards regression model were used to screen for the factors associated with the survival rate. Results: The median age of the patients was 48.6 years and the median follow-up period was 20 months. Three patients(20.0%) in the rescue OLT group and 15 patients (24.2%) in the de novo OLT group died during follow-up(P=0.73). The 30 day-mortality of OLT was 6.7% for the rescue OLT group vs. 1.6% for the de novo OLT group(P=0.27). Cox proportional hazards model showed that the presence of pre-OLT hyperbilirubinemia, requirement of post-OLT transfusion, size of the largest tumor, tumor macroembolism and family history of HCC were significantly associated with a higher hazard for mortality. Conclusion: No significant difference is found in the survival rates between OLT as de novo therapy and OLT as a rescue therapy for patients with HCC. Pre-OLT hyperbilirubinemia, post-OLT requirement of transfusion, size of the largest tumor, tumor macroembolism, and family history of HCC are associated with a poor survival outcome.
