ABSTRACT

Objective:To study the effect of first drainage failure on the prognosis of perihilar cholangiocarcinoma (PHCC).Methods:The clinical data of 68 patients with PHCC undergoing surgery in the Department of Pancreatic and Metabolic Surgery of Nanjing Drum Tower Hospital, Affiliated to the Medical School of Nanjing University, from April 2014 to December 2022 were retrospectively analyzed, including 46 males and 22 females, aged (63±9) (range, 39-80) years old. The patients were divided into two groups based on whether the first drainage was successful: successful group ( n=34) and failed group ( n=34). The patient's age, gender, first drainage, complications and other clinical data were collected. Patients were followed up by outpatient or telephone review. Kaplan-Meier method was used for survival analysis, and log-rank test was used for survival comparison. Results:Compared to the successful group, the drainage time [41(28, 52) d vs. 20(14, 28) d], the drainage tube adjustment rate [32.4%(11/34) vs. 0(0/34)], and the incidence of complications after drainage [88.2% (30/34) vs. 0(0/34)] were all increased in the failed group, with the adjustment rate of drainage position decreased [82.4%(28/34) vs. 100%(34/34)] (all P<0.05). Compared to the successful group, the incidence of abdominal infection was higher [70.6%(24/34) vs. 44.1%(15/34)] in the failed group ( P=0.027). The 5-year cumulative survival rates of the failed group and the successful group were 61.4% and 44.1%, respectively ( P>0.05). Conclusion:Compared to the patients of PHCC with first successful drainage, the risk of abdominal infection is increased when first drainage failed, while the incidence of postoperative complications, in-hospital mortality and long-term survival rate are comparable.

ABSTRACT

OBJECTIVE To explore the role of clinical pharmacists participating in the standardized perioperative nutritional management process for pancreaticoduodenectomy (PD) on improving postoperative recovery in patients. METHODS The clinical data of 100 patients undergoing PD in the Department of Biliary and Pancreatic Surgery, Drum Tower Hospital Affiliated to Nanjing University School of Medicine from November 2019 to February 2021 were analyzed retrospectively. According to the different perioperative nutrition management plans, they were divided into clinical pharmacist intervention group (n=51, clinical pharmacists intervened according to the standardized nutrition management process) and control group (n=49, clinical pharmacists only performed preoperative nutrition evaluation, and clinical physicians took nutrition support according to the patient’s condition). The differences in postoperative recovery index, economic evaluation index, hospitalization length, postoperative complications, and postoperative enteral nutrition support route were compared between 2 groups. RESULTS The time of postoperative diet, the first postoperative ventilation, the first postoperative defecation, and postoperative drainage time of abdominal drain were significantly earlier in the clinical pharmacist intervention group than in the control group (P<0.05); the hospitalization cost, medication cost, nutritional support cost, parenteral nutrition cost, albumin preparation cost, and the length of postoperative hospitalization were significantly lower/shorter in the clinical pharmacist intervention group than in the control group (P<0.05); there was no statistically significant difference in the incidence of postoperative complications between the two groups (P>0.05); there was statistically significant difference in the perioperative enteral nutrition support pathways between two groups (P<0.05). CONCLUSIONS Clinical pharmacists’ participation in perioperative nutritional management for PD can significantly reduce hospitalization costs and nutritional support costs, improve patients’ perioperative nutritional status, and shorten hospital stays. wanglina668@163.com

ABSTRACT

BACKGROUND@#After major liver resection, the volume status of patients is still undetermined. However, few concerns have been raised about postoperative fluid management. We aimed to compare gut function recovery and short-term prognosis of the patients after laparoscopic liver resection (LLR) with or without inferior vena cava (IVC) respiratory variability-directed fluid therapy in the anesthesia intensive care unit (AICU).@*METHODS@#This randomized controlled clinical trial enrolled 70 patients undergoing LLR. The IVC respiratory variability was used to optimize fluid management of the intervention group in AICU, while the standard practice of fluid management was used for the control group. The primary outcome was the time to flatus after surgery. The secondary outcomes included other indicators of gut function recovery after surgery, postoperative length of hospital stay (LOS), liver and kidney function, the severity of oxidative stress, and the incidence of severe complications associated with hepatectomy.@*RESULTS@#Compared with patients receiving standard fluid management, patients in the intervention group had a shorter time to anal exhaust after surgery (1.5 ± 0.6 days vs. 2.0 ± 0.8 days) and lower C-reactive protein activity (21.4 [95% confidence interval (CI): 11.9-36.7] mg/L vs. 44.8 [95%CI: 26.9-63.1] mg/L) 24 h after surgery. There were no significant differences in the time to defecation, serum concentrations of D -lactic acid, malondialdehyde, renal function, and frequency of severe postoperative complications as well as the LOS between the groups.@*CONCLUSION@#Postoperative IVC respiratory variability-directed fluid therapy in AICU was facilitated in bowel movement but elicited a negligible beneficial effect on the short-term prognosis of patients undergoing LLR.@*TRIAL REGISTRATION@#ChiCTR-INR-17013093.

ABSTRACT

Biliary tract cancers (BTC) is a type of digestive tract malignant tumors that originate from biliary epithelial cells, is characterized by strong occult and highly invasive, and has a high mortality rate. Early detection and diagnosis are considered to be the key to obtaining radical surgical treatment. R0 resection is an effective measure to benefit patients with BTC. However, most of the patients present with local progression or associated distant metastasis, making it impossible to undergo radical surgical treatment. With existing diagnosis and treatment methods, the 5-year survival rate of patients is still very low. Therefore, how to improve the level of diagnosis and treatment of BTC, prolong survival, and improve the quality of life has become an urgent problem to be solved. In view of the characteristics of BTC and the continuous deepening of clinical pathological molecular research, adjuvant therapy, precisely targeted therapy, immunotherapy, and comprehensive treatment are currently considered to be standardized diagnosis and treatment models and research directions beyond surgery. Therefore, this article systematically analyzes the current research progress of BTC both domestically and internationally, aiming to provide strategies for the diagnosis and treatment of patients with BTC.

ABSTRACT

Objective:To investigate the surgical efficacy and prognosis influencing factors of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment.Methods:The retrospective cohort study was conducted. The clinicopathological data of 91 patients with hilar cholangiocarcinoma who underwent surgery in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from April 2004 to April 2021 were collected. There were 59 males and 32 females, aged (61±10)years. Patients who were admitted from April 2004 to March 2014 underwent traditional surgical diagnosis and treatment, and patients who were admitted from April 2014 to April 2021 underwent multidisciplinary diagnosis and treatment. Observation indica-tors: (1) surgical situations; (2) postoperative situations; (3) postoperative pathological examina-tions; (4) postoperative prognosis analysis; (5) influencing factors of postoperative prognosis. Follow-up was conducted using telephone interview and outpatient examination. Patients were followed up once every 6 months after surgery to detect survival. The follow-up was up to April 2023. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of ordinal data was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to draw survival curve and calculate survival rate. The Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard model. Results:(1) Surgical situations. Of the 91 patients, there were 65 cases receiving hemi- or expanded hemi-hepatectomy, 13 cases receiving tri-hepatectomy, 9 cases receiving partial hepatectomy, 4 cases receiving extrahepatic bile duct resection. There were 24 cases receiving combined vein resection and reconstruction, 8 cases receiving combined pancreaticoduodenectomy, 6 cases receiving com-bined hepatic artery resection and reconstruction, including 24 cases receiving extended radical surgery (tri-hepatectomy, hepatic artery resection and reconstruction, hepatopancreaticoduodenec-tomy). The operation time, volume of intraoperative blood loss and intraoperative blood transfusion rate of 91 patients was (590±124)minutes, 800(range, 500?1 200)mL and 75.8%(69/91), respectively. Of the 91 patients, cases receiving extended radical surgery, the volume of intraoperative blood loss were 4, 650(range, 300?1 000)mL in the 31 patients who were admitted from April 2004 to March 2014, versus 20, 875 (range, 500?1 375)mL in the 60 patients who were admitted from April 2014 to April 2021, showing significant differences between them ( χ2=4.39, Z=0.31, P<0.05). (2) Post-operative situations. The postoperative duration of hospital stay and cases with postoperative infectious complications were (27±17)days and 50 in the 91 patients. Cases with abdominal infection, cases with infection of incision, cases with bacteremia and cases with pulmonary infection were 43, 7, 5, 8 in the 91 patients. One patient might have multiple infectious complications. Cases with bile leakage, cases with delayed gastric emptying, cases with chylous leakage, cases with liver failure, cases with pancreatic fistula, cases with intraperitoneal hemorrhage, cases with reoperation, cases dead during the postoperative 90 days were 30, 9, 9, 6, 5, 3, 6, 3 in the 91 patients. Cases with abdominal infection was 10 in the 31 patients who were admitted from April 2004 to March 2014, versus 33 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=4.24, P<0.05). Cases dead during the postoperative 90 days was 3 in the 31 patients who were admitted from April 2004 to March 2014, versus 0 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( P<0.05). (3) Post-operative pathological examinations. Of the 91 patients, cases with Bismuth type as type Ⅰ?Ⅱ, type Ⅲ, type Ⅳ, cases with T staging as Tis stage, T1 stage, T2a?2b stage, T3 stage, T4 stage, cases with N staging as N0 stage, N1 stage, N2 stage, cases with M staging as M0 stage, M1 stage, cases with TNM staging as 0 stage, Ⅰ stage, Ⅱ stage, Ⅲ stage, ⅣA stage, ⅣB stage, cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 46, 30, 1, 9, 25, 30, 26, 49, 36, 6, 85, 6, 1, 7, 13, 58, 6, 6, 63, 28. Cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 16 in the 31 patients who were admitted from April 2004 to March 2014, versus 48, 12 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=9.59, P<0.05). (4) Postoperative prognosis analysis. Of the 91 patients, 3 cases who died within 90 days after surgery were excluded, and the 5-year overall survival rate and median overall survival time of the rest of 88 cases were 44.7% and 55 months. The 5-year overall survival rate was 33.5% in the 28 patients who were admitted from April 2004 to March 2014, versus 50.4% in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=5.31, P<0.05). Results of further analysis showed that the corresponding 5-year overall survival rate of cases without lymph node metastasis was 43.8% in the 16 patients who were admitted from April 2004 to March 2014, versus 61.6% in the 31 patients who were admitted from April 2014 to April 2021. There was a significant difference in the 5-year overall survival rate between these patients without lymph node metastasis ( χ2=3.98, P<0.05). The corresponding 5-year overall survival rate of cases with lymph node metastasis was 18.5% in the 12 patients who were admitted from April 2004 to March 2014, versus 37.7% in the 29 patients who were admitted from April 2014 to April 2021. There was no significant difference in the 5-year overall survival rate between these patients with lymph node metastasis ( χ2=2.25, P>0.05). (5) Influencing factors of postoperative prognosis. Results of multivariate analysis showed that poorly differentiated tumor and R 1 or R 2 resection were inde-pendent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma ( hazard ratio=2.62, 2.71, 95% confidence interval as 1.30?5.29, 1.30?5.69, P<0.05). Conclusions:Compared with traditional surgical diagnosis and treatment, treatment of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment can expand surgical indications, reduce proportion of dead patients within 90 days after surgery, improve proportation of radical resection and long-term survival rate. Poorly differentiated tumor and R 1 or R 2 resection are independent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma.

ABSTRACT

Objective:To investigate the clinical efficacy of radical resection of pancreatic cancer after neoadjuvant conversion therapy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 23 patients who underwent radical resection of pancreatic cancer after neoadjuvant conversion therapy in Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2019 to May 2022 were collected. There were 17 males and 6 females, aged 58(range, 33-73)years. After neoadjuvant conversion therapy, the three-dimensional (3D) visualization was used to evaluate and classify tumor vascular invasion, and surgical plan was planned and implemented. Observation indicators: (1) situations of neoadjuvant conversion therapy; (2) surgical situations; (3) postoperative histopathological examination; (4) postoperative recovery; (5) follow-up. Measurement data with normal distribution were represen-ted as Mean± SD, and measurement data with skewed distribution were represented as M(range) or M( Q1, Q3). Count data were described as absolute numbers. Results:(1) Situations of neoadjuvant conversion therapy. All 23 patients received the AG combination chemotherapy (albumin-paclitaxel+gemcitabine), including 14 patients combined with stereotactic body radiation therapy. Of the 23 patients, 22 cases achieved partial response, and 1 case showed stable disease. The CA19-9 of the 23 patients was 85.06(29.74,634.5)U/mL and 13.96(9.74,25.02)U/mL before and after neoadjuvant conversion therapy, respectively. (2) Surgical situations. According to the results of preoperative 3D visualization of tumor vascular invasion, 7 of the 23 patients were evaluated as arterial invasion, 8 cases were evaluated as venous invasion, 5 cases were evaluated as arterial and venous invasion, and there were 3 cases showing negative of vascular invasion. Of the 23 patients, 12 cases underwent pancreaticoduodenectomy, 4 cases underwent radical antegrade modular pancreatosplenectomy, 7 cases underwent total pancreaticoduodenectomy. For vascular reconstruction, there were 10 patients without vascular reconstruction, and there were 13 patients undergoing artificial vascular vein reconstruction. The operation time and volume of intraoperative blood loss of the 23 patients was (524±171)minutes and 1 000(400,1 600)mL, respectively. (3) Postoperative histopathological exami-nation. Results of postoperative histopathological examination in 23 patients showed that there were 2 cases with moderate-well differentiated tumor, 10 cases with moderate differentiated tumor, 7 cases with moderate-poorly differentiated tumor, 2 cases with poorly differentiated tumor, and 2 cases negative of tumor. The number of lymph node dissected in 23 patients was 16±7. There were 5 cases with lymph node metastasis and 18 cases without lymph node metastasis. There were 17 cases with nerve invasion and 6 cases without nerve invasion. All 23 patients were negative of vascular invasion. Of the 23 patients, there were 21 cases with R 0 resection and 2 cases with R 1 resection. For pathological TNM staging, there were 2 cases with 0 stage, 13 cases with Ⅰ stage, 7 cases with Ⅱ stage, and 1 case with Ⅳ stage. For postoperative pathological scoring, there were 2 cases achieved 0 point (complete pathological remission), 16 cases achieved 2 points (partial remission), and 5 cases achieved 3 points (no significant effect). (4) Postoperative recovery. The postoperative duration of hospital stay of 23 patients was 19(14,31)days. There were 17 of 23 patients underwent postoperative complications, including 11 cases with Clavien-Dindo Ⅱ stage complications, 3 cases with Clavien-Dindo Ⅲa stage complications, 1 case with Clavien-Dindo Ⅲb stage complication, 1 case with Clavien-Dindo Ⅳ stage complication, and 1 case with Clavien-Dindo Ⅴ stage complica-tion. (5) Follow-up. There were 22 patients underwent follow-up, with follow-up time as 12(9,23)months. There were 9 patients underwent postoperative recurrence and metastasis, with recurrence and metastasis time as 7.8(range, 6.0-12.0)months. During the follow-up, 15 of the 22 patients survived. Conclusion:Radical resection of pancreatic cancer after neoadjuvant conversion therapy is feasible.

ABSTRACT

Objective:To construct a biospecimen bank of patient derived organoids (PDOs) from pancreatic cancer tissues and to explore the feasibility of PDOs drug sensitivity assay technology to guide chemotherapy drug selection for pancreatic cancer.Methods:Pancreatic cancer tissue specimens obtained after surgical resection and puncture biopsy from Mar 2020 to Dec 2022 at Drum Tower Hospital, Nanjing University School of Medicine were collected. Pancreatic cancer PDOs were cultured in vitro and histologically identified; PDOs were treated with gemcitabine, Nab-paclitaxel, fluorouracil, Oxaliplatin, and Irinotecan and cell viability was measured to analyze the correlation between PDOs drug sensitivity and the actual clinical treatment response.Results:The PDOs can reproduce the pathological features of corresponding tumor tissues; the sensitivity of different PDOs to the same chemotherapeutic drug is significantly different; The sensitivity of PDOs was highly consistent with the actual treatment effect of the corresponding patients 75.76% (25/33); organoid organ-based susceptibility testing had predictive value for the treatment response of patients (AUC=0.733, 95% CI: 0.546-0.919, P<0.05). Conclusion:A biobank of pancreatic cancer PDOs was successfully constructed, and the drug susceptibility test results were significantly correlated with the actual medication response of patients, suggesting that the drug susceptibility test technology based on PDOs has the potential to guide individualized chemotherapy for pancreatic cancer.

ABSTRACT

Objective:To investigate the application of accurate endoscopic retrograde cholangiopancreatography (ERCP)drainage guided by IQQA ?-Liver CT(an image interpretation and analysis system)to preoperative jaundice reduction for hilar cholangiocarcinoma. Methods:Data of 12 patients with hilar cholangiocarcinoma who planned to receive surgical treatment in the hepatobiliary surgery department of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from May 2017 to December 2018 were reviewed. All patients were treated with ERCP drainage before surgery. The procedure success rate, postoperative drainage volume and postoperative complications of the patients were analyzed.Results:ERCP was successful in all patients, and the median daily volume of endoscopic nasobiliary drainage was 675 mL(400-1 500 mL). Only 1 patient developed postoperative cholangitis, and another patient developed postoperative mild pancreatitis. The mean serum total bilirubin was 173.3±62.8 μmol/L in the patients before ERCP, which decreased to 35.6±13.9 μmol/L before surgery.Conclusion:Accurate ERCP drainage can effectively reduce the serum bilirubin level in patients with hilar cholangiocarcinoma and reduce the incidence of cholangitis after the procedure, creating favorable conditions for subsequent surgical operations.

ABSTRACT

Objective:To investigate the application value of pancreatoduodenectomy (PD) with preservation of the gastric tube.Methods:The retrospective and descriptive study was conducted. The clinicopathological date of 3 male patients who underwent PD with preservation of the gastric tube for the treatment of periampullary tumor in Nanjing Drum Tower Hospital affiliated to Nanjing University Medical School from May 2018 to November 2019 were collected. The 3 patients were aged from 66 to 77 years, with a median age of 76 years. All 3 patients with surgical history of radical resection of esophageal tumors and tubular gastric surgery underwent PD with preservation of the gastric tube. Observation indications: (1) preoperative three-dimensional (3D) reconstruction; (2) surgical and postoperative situations; (3) follow-up. Follow-up using outpatient exa-mination or telephone interview was conducted to detect survival of patients and tumor metastasis and recurrence up to April 2021. Measurement date with skewed distribution were expressed as M(range).Count date were expressed as absolute numbers. Results:(1) Preoperative 3D recons-truction: results of preoperative 3D reconstruction for the 3 patients showed none of patients with vascular variation. (2) Surgical and postoperative situations: 3 patients underwent PD with preserva-tion of the gastric tube successfully. The operation time and the volume of intraoperative blood loss were 402 minutes(range, 345?480 minutes) and 330 mL(range, 300?400 mL) for the 3 patients. Of 3 patients, 1 case had postoperative grade B pancreatic fistula and 1 case had chylous leakage, respectively, who were improved after conservative treatment. There was no perioperative death. The duration of postoperative hospital stay was 18 days(range, 15?20 days) for the 3 patients. Results of postoperative histopathological examination for the 3 patients showed that 1 case with pancreatic cancer as T2N0M0 stage, 1 case with ampulla carcinoma as T2N0M0 stage and 1 case with intraductal papillary mucinous neoplasms of the pancreas. (3) Follow-up: 3 patients were followed up for 12 to 18 months, with a median follow-up time of 16 months. Results of abdominal enhanced computed tomography examination at postoperative 14 month for the 3 patients showed that the right gastroepiploic artery and vein around the pancreas were unobstructed. Of 3 patients, 1 case with pancreatic cancer who did not receive chemotherapy died at postoperative 14 months due to tumor recurrence and metastasis. There was no recurrence and metastasis in the other two cases.Conclusion:PD with preservation of the gastric tube is safe and feasible, which can be used for patients with periampullary lesions who underwent radical resection of esophageal tumors and tubular gastric surgery in the past.

ABSTRACT

Objective:To identify the risk factors of clinically relevant pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD) for Vater′s ampullary carcinoma.Methods:The clinical data of 93 Vater's ampullary carcinoma patients who had undergone PD in Nanjing Drum Tower Hospital from January 2018 to December 2020 was retrospectively analyzed. According to the occurrence of CR-POPF, all patients were divided into the CR-POPF group and no CR-POPF group. Univariate analysis and multivariate analysis by logistic regression model were performed for perioperative risk factors of CR-POPF to identify the independent risk factors for CR-POPF after PD for Vater's ampullary carcinoma.Results:44 patients developed CR-POPF and the rate of CR-POPF was 47.3%(44/93). The most frequently detected microorganisms from abdominal drain fluid after operation were Klebsiella pneumoniae (25.8%), Enterococcus faecalis (19.4%), Enterobacter cloacae (11.8%) and Enterococcus faecium (10.7%). The results of univariate analysis showed that operation time, C-reactive protein (CRP) on postoperative day (POD)1, Klebsiella pneumoniae, Enterococcus faecalis and Enterococcus faecium in the abdominal drainage were statistically different between the two groups (all P value <0.05). Multivariate analysis revealed that CRP on POD1 ( OR 1.029, 95% CI 1.003-1.055, P=0.026), Klebsiella pneumoniae( OR 8.671, 95% CI 2.366-31.772, P=0.001), Enterococcus faecalis( OR 10.497, 95% CI 2.306-41.776, P=0.002) and Enterococcus faecium ( OR 22.580, 95% CI 2.303-221.403, P=0.007) in the abdominal drainage were independent risk factors for the development of CR-POPF after PD for Vater′s ampullary carcinoma. Conclusions:CRP on POD1, Klebsiella pneumoniae, Enterococcus faecalis and Enterococcus faecium in the drain samples were independent risk factors for the development of CR-POPF after PD for Vater′s ampullary carcinoma.

ABSTRACT

Objective:To compare the clinical efficacy of the Simultaneous three scopes combined surgery [laparoscopic cholecystectomy(LC)+ choledochoscopy exploration + choledochectomy and removal of the common bile duct + primary suture of the common bile duct + endoscopic guided nasobiliary duct placement] and staged two scopes surgery[endoscopic retrograde cholangiopancreatography (ERCP) combined with LC] in the treatment of choledocholithiasis and cholecystolithiasis.Methods:From January 2018 to June 2020, we retrospectively analyzed the clinical data of 83 patients with choledocholithiasis and choledocholithiasis, who underwent minimally invasive treatment in our center. According to the different surgical procedures, the patients were divided into three-mirror group ( n=42) and two-mirror group ( n=41). All patients in the three-mirror group underwent three-scopy combined surgery. The patients in two-mirror group received endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy (LC). In this study we compared the relevant clinical indicators of the two groups, in terms of the operation time, intraoperative blood loss, one-time stone clearance rate, postoperative exhaust time, postoperative defecation time, total hospitalization cost, incidence of postoperative acute pancreatitis, postoperative stone recurrence rate, incidence of postoperative cholangitis, and incidence of postoperative biliary fistula, total hospitalization time, postoperative bile duct stricture rate. Use SPSS 26.0 software to statistically analyze various indexes such as intraoperative, postoperative, follow-up, etc. Normally distributed measurement data were described by the mean±standard deviation ( Mean± SD), the comparison between groups was by t test, and measurement data with skewed distribution were destribed as M( P25, P75), Pairwise comparisons were analyzed using nonparametric test. The comparison of count data between groups was by the chi-square test. Results:No death was observed in both two groups. The operation time, intraoperative blood loss, one-time stone clearance rate, postoperative exhaust time, and postoperative defecation time of the three-mirror groupwere (167.98±47.37) min, 50(50, 100) mL, 100%(42/42), (2.10±0.76) days, 3(3, 4) days, the two-mirror group were (143.80±34.47) min, 50(50, 50) mL, 85.4%(35/41), (1.53±0.99) days and 2(1, 3) days. Compared with the two groups, the three-mirror group was higher than the two-mirror group, and the difference was statistically significant ( P<0.05). The total hospitalization expenses, postoperative acute pancreatitis incidence, and postoperative calculus recurrence rate in the three-mirror group were (3.46±0.77) ten thousand yuan, 0(0/42), 2.38%(1/42), the two-mirror group were (4.22±1.50) ten thousand yuan, 9.8%(4/41), 19.5%(8/41). Compared with the two groups, the three-mirror group was lower than the two-mirror group, and the difference was statistically significant ( P<0.05). No postoperative cholangitis or biliary fistula occurred in the two groups. There was no statistically significant difference in the total hospital stay and incidence of postoperative bile duct stenosis between the two groups ( P>0.05). Conclusions:For choledocholithiasis combined with cholecystolithiasis patients, simultaneous three-scopes combined surgery and elective LC after ERCP are safe and effective, and each has its own advantages. It should be selected reasonably according to the patient′s condition and combined with the technical advantages of the treatment team.

ABSTRACT

Objective:To review our clinical experience on total pancreatectomy in treatment of pancreatic diseases.Methods:The clinical data of 25 patients with pancreatic diseases who underwent total pancreatectomy at Nanjing Drum Tower Hospital from February 2016 to October 2019 were retrospectively analyzed. The data on general information, surgical methods, postoperative complications, changes in postoperative pancreatic endocrine and exocrine functions and quality of life were analyzed.Results:There were 16 males and 9 females, aged (60.9±9.4) years. Planned selective surgery was carried out in 16 patients while unplanned operations in 9 patients. There were 15 patients with pancreatic neoplasms with 4 patients who received neoadjuvant or conversion therapy, 6 patients with intraductal papillary mucinous neoplasms, 3 patients with chronic pancreatitis and 1 patient with pancreatic neuroendocrine carcinoma. The total postoperative complication rate was 36% (9/25). One patient died in the perioperative period, and one patient underwent a second operation. After 6 months of operation, 2 of 24 patients had died. The remaining patients had a fasting blood sugar of (8.9±1.6) mmol/L, with an insulin dosage of (30.7±10.6) U/d. The average dosage of trypsin was (1.1±0.3) g/d. The quality of life score reached or exceeded the preoperative levels.Conclusions:Total pancreatectomy was safe and feasible for some pancreatic diseases. For patients with pancreatic cancer, its long-term oncological outcomes need further studies.

ABSTRACT

Objective:To investigate the effect of logistic regression model based on virtual touch tissues quantification (VTQ) and fibrosis index based on four factors (FIB-4) in assessing impaired liver reserve function (LFR) in hepatic surgery patients before surgical resection.Methods:From January 2016 to October 2018, 173 patients including 135 males and 38 females with the mean age of 58.6 years old, scheduled for potential hepatectomy in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, were enrolled in our retrospective study. According to indocyanine green retention test at 15 minutes (ICG R15), the patients were divided into two groups, LFR-impaired group ( n=11, ICG R15≥20%) and control group ( n=162, ICG R15 < 20%). VTQ, FIB-4, platelet count and other parameters were compared between two groups. The multivariate logistic regression model was used to establish a risk model to access the impaired LFR. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of each parameter in LFR-impaired. Results:The platelet count in LFR-impaired group was lower than that in control group, VTQ and FIB-4 were higher than that in control group (all P<0.05). Logistic regression showed that VTQ ( OR=4.382, 95% CI: 1.380-13.918)) and FIB-4 ( OR=2.112, 95% CI: 1.342-3.325) were risk factors for LFR-impaired. The final prediction model of LFR-impaired group was Logit (P)=-6.185+ 0.748×FIB-4+ 1.477×VTQ. The cut-off point (sensitivity, specificity, accuracy) of logistic model, FIB-4 and VTQ were 0.098 (72.8%, 90.1%, 89.0%), 0.990 (90.9%, 79.0%, 79.8%) and 1.8 m/s (81.8%, 77.8%, 78.0%), respectively. The specificity, accuracy of logistic model was higher than FIB-4 or VTQ. Conclusions:Logistic regression model based on VTQ and FIB-4 may improve the specificity and accuracy in the diagnosis of significant LFR impairment. VTQ can further assist clinicians in preoperative evaluation of LFR.

ABSTRACT

Preoperative biliary drainage (PBD) has become an essential part of perioperative management for perihilar cholangiocarcinoma. However, it is controversial about the indication of PBD. There are three main PBD methods, including percutaneous transhepatic biliary drainage, endoscopic nasobiliary drainage and endoscopic biliary stenting. At present, different centers have different preferences on PBD, and the controversies mainly focus on the followings: the relationship between percutaneous transhepatic biliary drainage and seeding metastasis; the success rate, tolerance and pancreatitis risk of endoscopic nasobiliary drainage; as an internal drainage, the merits and demerits of endoscopic biliary stenting. Additionally, whether PBD could increase the incidence of postoperative infections is still ambiguous. This review summarizes the recent scenario about the above-mentioned controversies to provide references for clinical decision-making.

ABSTRACT

Objective:To investigate the influencing factors for pancreatic endocrine and exocrine insufficiency after pancreaticoduodenectomy.Methods:The retrospective case-control study was conducted. The clinicopathological data of 168 patients who underwent pancreaticoduodenectomy in the Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2016 to December 2017 were collected. There were 96 males and 72 females, aged (64±13)years, with a range from 38 to 75 years. Of the 168 patients, 36 had pancreatic endocrine insufficiency while 8 had pancreatic exocrine insufficiency preoperatively. All patients underwent pancreaticoduodenectomy. Observation indications: (1) surgical situations and follow-up; (2) analysis of influencing factors for pancreatic endocrine insufficiency after pancreaticoduodenectomy; (3) analysis of influencing factors for pancreatic exocrine insufficiency after pancreaticoduodenectomy. Follow-up using out-patient examination and telephone interview was performed to detect postoperative condition of blood glucose control, diet and nutrition, tumor recurrence and metastasis up to June 2018. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement data with skewed distribution were described as M (range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the chi-square test. Multivariate analysis was conducted using the Logistic regression model. Results:(1) Surgical situations and follow-up: all the 168 patients underwent pancreaticoduodenectomy successfully and recovered well after operation. All patients were followed up for 6 months. The level of fasting and postprandial blood glucose of the 168 patients after surgery were 7 mmol/L(range, 5-9 mmol/L) and 10 mmol/L(range, 7-14 mmol/L), respectively. The defecation frequency was (2.4±1.2)times per day. No tumor recurrence or metastasis occurred in either patient. One hundred and thirty-two of the 168 patients were included in the study excepting patients with pancreatic endocrine insufficiency before operation. At postoperative 6 months, 47 patients developed pancreatic endocrine insufficiency, with an incidence of 35.61%(47/132). One hundred and sixty of the 168 patients were included in the study excepting patients with pancreatic exocrine insufficiency before operation. At postoperative 6 months, 68 patients had pancreatic exocrine insufficiency, with an incidence rate of 42.50%(68/160). (2) Analysis of influencing factors for pancreatic endocrine insufficiency after pancreaticoduodenectomy. Results of univariate analysis showed that gender, metabolic syndrome, chronic pancreatitis, excision point, and postoperative chemotherapy were the related factors for pancreatic endocrine insufficiency after pancreaticoduodenectomy ( χ2=5.300, 6.270, 4.473, 4.392, 5.397, P<0.05). Results of multivariate analysis revealed that male and metabolic syndrome were independent risk factors for pancreatic endocrine insufficiency after pancreaticoduodenectomy [ hazard ratio ( HR)=5.252, 5.364, 95% confidence interval ( CI): 1.362-6.382, 1.891-12.592, P<0.05)]. (3) Analysis of risk factors for pancreatic exocrine insufficiency after pancreaticoduodenectomy. Results of univariate analysis showed that body mass index (BMI), chronic pancreatitis, total bilirubin, excision point, postoperative pancreatic fistula as grade B or C, and pancreatic fibrosis were related factors for pancreatic exocrine insufficiency after pancreaticoduodenectomy ( χ2=1.691, 4.910, 7.763, 5.605, 4.663, 7.700, P<0.05). Results of multivariate analysis showed that BMI<18.5 kg/m 2, chronic pancreatitis, total bilirubin ≥171 μmol/L were independent risk factors for pancreatic exocrine insufficiency after pancreaticoduodenectomy ( HR=3.695, 5.231, 7.623, 95% CI: 1.232-7.324, 2.161-6.893, 1.562-5.235, P<0.05). Conclusions:Male and metabolic syndrome are risk factors for pancreatic endocrine insufficiency after pancreaticoduodenectomy. BMI<18.5 kg/m 2, chronic pancreatitis, and total bilirubin ≥171 μmol/L are risk factors for pancreatic exocrine insufficiency after pancreaticoduodenectomy.

ABSTRACT

Objective:To study the risk factors and microbial spectrum for infectious complications for patients with biliary tract cancer after major hepatectomy with cholangiojejunostomy.Methods:Enrolled into this study were 78 consecutive patients (57 patients with perihilar cholangiocarcinoma, 17 with intrahepatic cholangiocarcinoma and 4 with gallbladder cancer), who underwent major hepatectomy with cholangiojejunostomy at Nanjing Drum Tower Hospital between September 2010 and March 2019. The clinical data were reviewed using multivariate analysis to find independent risk factors for postoperative infectious complications. Microorganisms isolated from bile and infected sites were determined to study the microbial spectrum.Results:A total of 45(57.7%) patients suffered from postoperative infectious complications. Male sex ( OR=7.765, 95% CI=1.895-31.815, P<0.05) was the independent risk factor, whereas increased preope-rative red blood cell (RBC) ( OR=0.151, 95% CI=0.038-0.592, optimal cut-off value=3.7×10 12/L) and increased total cholesterol (TC) on postoperative day (POD) 1 ( OR=0.227, 95% CI=0.083-0.626, optimal cut-off value=3.5 mmol/L) were protective factors (both P<0.05). The area under the receiver operating characteristic (ROC) curve was 0.805 (95% CI=0.707-0.902, P<0.05). 205 and 230 microorganisms were cultured respectively from 286 and 681 specimens which were collected from pre-/intraoperative bile and potentially infected sites. Staphylococcus, enterococcus, acinetobacter, klebsiella and pseudomonas were the most common pathogens on bile culture. The first 5 most frequently isolated microorganisms from the infected sites were enterococcus, staphylococcus, klebsiella, candida and xanthomonas. Sixteen (61.5%) of 26 patients had at least one pathogen being isolated from the infected sites with the pathogen being previously isolated in bile culture. Conclusions:Male sex were independent risk factors of infectious complications. Increased preoperative RBC and inreased TC on POD were proteetive factors. For patients without a positive bile culture, a third-generation cephalosporin can be considered as a prophylactic antibiotic. It is important to identify high-risk patients and monitor perioperative pathogens actively to prevent and to cure postoperative infectious complications.

ABSTRACT

Objective To evaluate the prognostic value of pathological characteristics of microvascular invasion (MVI) in patients with hepatocellular carcinoma (HCC).Methods 289 consecutive HCC patients who underwent curative hepatectomy at Nanjing Drum Tower Hospital from January 2007 to December 2015 were retrospectively studied.These patients were divided into three groups:the no-MVI group (n =176),the low-MVI group (the number of invaded microvessels ≤ 5 and the distance of invasion ≤ 1 cm,n =53) and the high-MVI group (the number of invaded microvessels > 5 or the distance of invasion > 1 cm,n =60).The clinical and pathological data and the survival outcomes of these HCC patients were analyzed.We further compared the prognosis among the three groups.Results Kaplan-Meier survival indicated that the number of invaded microvessels > 5 and the distance of invasion > 1 cm were associated with cumulative and recurrence-free survival rates of HCC patients.The cumulative and recurrence-free survival rates of the high-MVI group were significantly poorer than those of the low-MVI and the no-MVI groups.Multivariate analysis showed ICG-R15 (HR =1.049,95% CI:1.002 ~ 1.097),tumor size (HR =1.138,95% CI:1.043 ~ 1.241),and high-MVI (HR =3.245,95% CI:1.946 ~ 5.413) were independent risk factors for cumulative survival.Tumor size (HR =1.117,95% CI:1.050 ~ 1.188),and high-MVI (HR =2.222,95% CI:1.540 ~ 3.205) were independent risk factors for recurrence-free survival.The prognosis of the no-MVI and low-MVI groups were significantly better than the high-MVI group (P < 0.05).The recurrence rates of the low-MVI and no-MVI groups (49.4% and 67.9%) were significantly lower than the high-MVI group (80.0%,P < 0.05).Conclusions The risk classification of MVI based on histopathological features was valuable in predicting prognosis of HCC patients.We could use the risk classification of MVI to establish a follow-up and individualized treatment plan for HCC patients.

ABSTRACT

Objective@#To evaluate the safety and efficacy of helical tomotherapy using simultaneously integrated boost and simultaneous integrated protection technique in the treatment of unresectable biliary tract cancers.@*Methods@#The data of 23 patients with unresectable biliary tract cancer who received tomotherapy-based hypofractionated radiotherapy at Comprehensive Cancer Centre of Drum Tower Hospital,the Affiliated Drum Tower Clinical College of Nanjing Medical University between February 2015 and October 2017 were analyzed. There were 10 males and 13 females, aged from 40 to 85 years(median:58 years). Pathological type included intrahepatic cholangiocarcinomas(n=11), gallbladder cancers(n=6),extrahepatic cholangiocarcinomas(n=6). The irradiated sites covered primary tumors and areas of local invasion,including metastatic lymph nodes which were confined to the abdominal or retroperitoneal space. Dose escalation was achieved using simultaneously integrated boost(SIB) technique, and simultaneous integrated protection(SIP)technique was used to protect gastrointestinal tracts and other adjacent organs. Cox regression modal and Kaplan-Meier analysis were used to analyze the associations between patients′ characteristics and overall survival(OS).@*Results@#The median total radiation dose was 54 Gy(range: 28-72 Gy)and median biologically effective dose(BED)was 74.4 Gy(range: 37.8-115.2 Gy).The median planning target volume(PTV)was 445.79 cm3(range:126.02-950.12 cm3). Based on the various PTV,patients received 2.4-6.0 Gy/fraction with 8-28 fractions. The local control rate was 65.2% and the median OS was 11.3 months(range:2.1-31.9 months).The most common cause of death was out-field failure and only 3 patients died of in-field failures. The longest survival was 31.9 months. BED≥70 Gy significantly improved OS,compared to BED<70 Gy(16.8 months vs.5.1 months)(HR=0.146, 95%CI:0.028-0.762, P=0.022). No patients developed grade ≥4 toxicities.@*Conclusions@#Helical tomotherapy-based hypofractionated radiotherapy is effective and well tolerated for patients with unresectable biliary tract cancer. The dose escalation with higher BED could improve the survival for such patients.
