ABSTRACT
Peribiliary glands (PBG) is a kind of microscopic structure around the intra-hepatic bile ducts and extrahepatic bile ducts. PBG not only participates in maintaining the normal physiological function of biliary epithelial tissue, but also plays an important role in its damage and repair process. Biliary tree stem/progenitor cells in PBG are important cell sources of biliary epithelial regeneration and repair. PBG and the surrounding peribiliary vascular plexus are key influencing factors for the occurrence of ischemic-type biliary lesions (ITBL) after liver transplantation. Based on relevant literatures and clinical practice, the authors summarize the function of PBG as well as its relationship with ITBL.
ABSTRACT
Objective:To evaluate the short-term efficacy of split liver transplantation (SLT) in patients with acute-on-chronic liver failure (ACLF).Methods:The clinical data of 9 ACLF patients receiving SLT in our center from Mar 2021 to May 2022 were retrospectively analyzed to evaluate its safety and efficacy.Results:The preoperative APASL ACLF Research consortium (AARC) score of the 9 ACLF patients was 8 points in 1 case, 9 points in 3 cases, 10 points in 3 cases, 11 points in 1 case and 12 points in 1 case, 7 cases were in AARC-ACLF grade 2, and 2 cases in grade 3.In-situ liver splitting was performed in 9 deceased donors, including 4 classical split cases, 5 full size split cases. Among these 9 ACLF patients, 2 received left half liver transplantation, 3 received right half liver transplantation, and 4 received extended right lobe liver transplantation. After transplantation, all 9 recipients were discharged fully recovered, 1 case developed Clavien grade Ⅳa complication and 2 cases developed Clavien grade Ⅲb complication.After SLT treatment the median postoperative hospital stay was 27 days, the 1-year survival rate was 100%, and the organ survival rate was 88.9%.Conclusion:Split liver transplantation is a safe and feasible treatment method for ACLF patients.
ABSTRACT
Objective:To investigate the risk factors for postoperative early recurrence of patients with single large hepatocellular carcinoma (HCC) (tumor diameter≥5cm).Methods:Clinical data of 135 single large HCC patients who underwent radical resection from Jan 2015 to Sep 2020 in Ningbo Medical Centre Lihuili Hospital were analyzed.Results:Seventy-five HCC patients suffered recurrence,among those 42 patients had early recurrence(within 12 months). Multivariate analysis showed that alpha-fetoprotein (AFP)≥400 ng/ml ( OR=3.510,95% CI: 1.528-8.064; P=0.003) and tumor microvascular invasion (MVI) ( OR=2.769,95% CI: 1.143-6.706; P=0.024) were independent risk factors for early recurrence of single large hepatocellular carcinoma. Survival analysis showed that early recurrence risk factors significantly reduced recurrence free survival (RFS)(AFP≥400 ng/ml, χ 2=23.038, P<0.001; MVI positive , χ 2=10.554, P=0.001) and overall survival (OS) (AFP≥400 ng/ml, χ 2=14.336, P<0.001; MVI positive, χ 2=10.481, P=0.001) in single large hepatocellular carcinoma patients. Conclusion:AFP≥400 ng/ml and MVI positive are independent risk factors for postoperative early recurrence in single large hepatocellular carcinoma patients.
ABSTRACT
Objective:To investigate the impact of initial recurrence site on the prognosis of patients with pancreatic cancer after radical operation.Methods:Clinical data of 172 patients who underwent radical resection of pancreatic cancer and were pathologically confirmed as pancreatic ductal adenocarcinoma in Ningbo University Affiliated Lihuili Hospital from January 2015 to June 2021 were analyzed retrospectively. According to the classification of the initial recurrence or metastasis after operation: no recurrence, local recurrence (residual pancreas, mesenteric vein, pancreaticoenterostomy surrounding tissue), liver metastasis, abdominal or retroperitoneum metastasis, multiple site recurrence and other pattern recurrence. The effect on prognosis was analyzed by COX risk ratio model, the overall survival and recurrence-free survival were calculated by Kaplan-Meier, and the survival curve was drawn. Log-rank test was used to compare the survival rate of different recurrence sites and different treatments after recurrence.Results:12 patients had local recurrence, 69 had liver metastasis, 25 had abdominal or retroperitoneal metastasis, 17 had multiple site recurrence, and 5 had other site recurrence and 44 had no recurrence. The median follow-up time was 15.5 months (3-69 months). The median overall survival was 19 months (95% CI 16.273-21.727). The 1- , 3- and 5-year postoperative cumulative survival rate was 71.0%, 27.8% and 20.2%, respectively. Univariate analysis showed that CA125, tumor size, lymph node metastasis, microvascular invasion, tumor differentiation degree, adjuvant chemotherapy, initial recurrence site were significantly correlated with overall survival (All P value <0.05). Multivariate analysis showed that CA125 ≥30 IU/ml ( OR=2.669, P=0.001), microvascular invasion ( OR=1.736, P=0.028), poor tumor differentiation ( OR=1.604, P=0.027), adjuvant chemotherapy ( OR=0.439, P<0.001), initial recurrence site (All P value <0.05) were the independent risk factors for overall survival. The median recurrence-free survival of 172 patients was 9 months (95% CI 7.075-10.925). Univariate analysis showed that CA125, tumor size, lymph node metastasis and microvascular invasion were significantly correlated with recurrence-free survival (All P value <0.05). Multivariate analysis showed that CA125 ( OR=1.640, P=0.026), tumor size ( OR=1.774, P=0.011) and microvascular invasion ( OR=1.563, P=0.034) were the independent risk factors for recurrence-free survival. After surgery, the median survival time of patients with local recurrence, other pattern recurrence, abdominal or retroperitoneal metastasis, multi-site recurrence and liver metastasis was 28, 22, 21, 15 and 14 months, respectively. Among them, the overall survival of patients with postoperative local recurrence was longest, which was significantly longer than that of patients with multi-site recurrence ( P=0.035) and liver metastasis ( P=0.007); the survival of patients with abdominal or retroperitoneal metastasis was also longer than that with liver metastasis ( P=0.005); and all the differences were statistically significant. In 128 patients with recurrence, the median overall survival of 26 patients without adjuvant therapy was 10 months (95% CI 6.877-13.123); the median overall survival of 68 patients with adjuvant chemotherapy was 15 months (95% CI 13.013-16.987); the median overall survival of 34 patients with comprehensive treatment of surgery and radiotherapy was 19 months (95% CI 15.100-22.900), which was significantly higher than the other two groups, and there were significant statistical differences among the three groups ( P<0.001). Conclusions:The initial recurrence site of pancreatic cancer after radical operation is an independent risk factor for overall survival. Compared with local recurrence and abdominal or retroperitoneal metastasis, patients with multi-site recurrence and liver metastasis have a poor prognosis. Comprehensive treatment after recurrence can significantly prolong the overall survival.
ABSTRACT
Objective:To study the safety and efficacy of combining portal vein resection and reconstruction (PVR) with resection of perihilar cholangiocarcinoma (PHC).Methods:A total of 104 patients with PHC who underwent hepatectomies for either biliary resection alone or biliary resection combined with PVR from October 2006 to December 2019 at the Department of Hepatopancreatobiliary, Ningbo Medical Center of Lihuili Hospital entered into this study. There were 63 males and 41 females, with the age of (64.4±10.4) years. The control group consisted of 75 patients who underwent biliary resection alone, while the PVR group consisted 29 patients with biliary resection combined with PVR. The patient characteristics and the follow-up outcomes of the two groups were analyzed and compared. Survival analyses were performed using the Kaplan Meier method with the log-rank test.Results:Wedge resection of portal vein, side to side anastomosis in 2 cases, segmental resection and end to end anastomosis in 27 cases. The time taken for PVR and portal vein resection were (12.7±2.9)(range 8 to 18)min and (20.7±7.3)(range 8 to 38) mm, respectively. The estimated blood loss for the PVR group was significantly more than the control group [ M( Q1, Q3)] 800.0 (600.0, 1 500.0) ml vs. 600.0(500.0, 1 000.0) ml ( P<0.05). Based on postoperative pathological studies, the proportion of lymph node metastasis was significantly higher in the PVR group than the control group (58.6% vs. 32.0%, P<0.05). Clavien-Dindo grade Ⅲ and above complications were 30.7%(23/75) and 34.5%(10/29) in the control and PVR groups, respectively ( P>0.05). The re-operation and postoperative 90 days mortality rates were 9.3%(7/75) and 2.7%(2/75) in the control group, compared with 3.4%(1/29) and 0 in the PVR group, respectively (both P>0.05). The 1-, 3- and 5-year survival rates were 81.1%, 44.8% and 36.4% respectively for the control group and 78.1%, 35.9% and 31.4% for the PVR group (χ 2=0.33, P=0.570). Conclusion:When compared to biliary resection alone, biliary resection combined with PVR did not significantly increase postoperative complication and mortality rates, but with comparable long-term survival outcomes. Combined biliary resection with PVR was safe and improved the resection rate in selected patients with locally advanced PHC.
ABSTRACT
Objective:To analyse the risk factors of biliary leakage after surgical resection in patients with perihilar cholangiocarcinoma (PHCC).Methods:The medical data on 179 patients who underwent surgical resection for PHCC at the Department of Hepatopancreatobiliary Surgery, Ningbo Medical Centre Lihuili Hospital, Ningbo University from April 2000 to April 2020 were collected, and 160 patients were finally enrolled into this study. There were 86 males and 74 females, aged (63.4±10.8) years. The 44 patients with class B biliary leakage and the 5 patients with class C biliary leakage were classified into the biliary leakage group, while the remaining 111 patients were classified into the control group. Risk factors of biliary leakage were analysed by univariate and multivariate logistic regression analyses.Results:Operation time ≥360 min, resection and reconstruction of hepatic hilar vessels on the preserved side of liver and number of bile duct openings of >3 in remnant liver were significantly higher in the biliary leakage than the control group (all P<0.05). Multivariate analysis showed that resection and reconstruction of hepatic hilar vessels on the preserved side ( OR=2.322, 95% CI: 1.078-5.002, P=0.028) and 3 or more bile duct openings in the remnant liver ( OR=2.656, 95% CI: 1.198-5.892, P=0.016) were significantly associated with biliary leakage. Conclusion:Resection and reconstruction of hepatic hilar vessels on the preserved side of liver and 3 or more bile duct openings in remnant liver were independent risk factors for biliary leakage after PHCC resection.
ABSTRACT
Objective:To explore the feasibility of technological modification and innovation of full-left/full-right liver splitting in situ for donors and examine the safety of clinical application for liver transplantation (LT).Methods:From March 2021 to June 2022, clinical and surgical data are retrospectively reviewed for 27 donors undergoing full-left/full-right liver splitting in situ and the corresponding 49 recipients undergoing full-left/full-right LT.According to the split liver technique used in donor liver surgery, they are divided into conventional split group(group A, 13 cases)and innovative split group(group B, 14 cases). The corresponding recipients are divided into two groups of recipient C(25 cases)and recipient D(24 cases). General profiles, intraoperative findings, type of vascular allocation and short-term outcomes in two groups are compared.After full-size split liver transplantation(fSLT), follow-ups continued until the end of September 2022.Results:There are 23 males and 4 females in donors.The causes of mortality for donors are traumatic head injury(12 cases)cerebrovascular accident(13 cases)and anoxia encephalopathy(2 cases). Baseline characteristics of two groups indicate that body weight and body mass index(BMI)are higher in group B and blood sodium level is lower than that in group A( P<0.05). No statistical differences exist for the others.Liver splitting time is significantly shorter in group B than that in group A(175 vs.230 min, P=0.022). No significant inter-group difference exists in type of vascular allocation.Retrohepatic inferior vena cava(IVC)is split in one case in group A and 10 cases in group B( P=0.001). Among 20 cases of right hemiliver requiring a reconstruction of segment Ⅴ/Ⅷ venous outflow, 12 cases in group A and 3 cases in group B are reconstructed with conventional independent bridging method(independent type)while another 5 cases in group B reconstruct with innovated technique by bridging Ⅴ/Ⅷ vein for splitting IVC with iliac vessel and molding all outflows as one for anastomosis(combined typ e). There is significant inter-group difference( P=0.004). No significant differences exist in operative duration, anhepatic phase or blood loss between groups C and B, except for T tube retaining in 7 cases of group A and 14 cases of group D( P=0.032). Twelve cases developed a total of 26 instances of≥Clavien-Dindo grade Ⅲ complications.Of which, 7 cases in group C and 5 cases in group D show no significant difference in postoperative morbidity.However, for serious biliary complications(≥Clavien Dindo grade Ⅲ), there are 6 cases in group C versus none in group D( P=0.016). Two cases died from postoperative complication with a postoperative mortality rate of 4.1%.Postoperative hospital stay is similar in two groups.And accumulates 6/12-month survivals were 95.9% and 87.7% for grafts and 95.9% and 92.4% for recipients respectively. Conclusions:Operative duration of full-left/full-right liver splitting in situ tends to shorten with an accumulation of a certain amount of cases.Technological modification and innovation in IVC splitting and segment Ⅴ/Ⅷ vein reconstruction should be further validated as both feasible and safe by short-term outcomes of the corresponding recipients.
ABSTRACT
Objective:To investigate the correlation between modified Glasgow prognostic score (mGPS) and prognosis of intrahepatic cholangiocarcinoma (ICC) patients after radical surgical resection.Methods:The clinical data of 126 patients with intrahepatic cholangiocarcinoma undergoing radical surgical resection at Ningbo Medical Centre Lihuili Hospital from Jan 2011 to Dec 2020 were retrospectively analyzed. The patients were scored according to the mGPS-related scoring standards, and the differences in tumor clinicopathological characteristics and prognosis were compared between patients with different score levels.Results:Firty-eight cases were included in group 0, 41 cases in group 1, and 27 cases in group 2. The 1- and 3-year survival rates in group 0 were 85.8% and 52.3%, the 1- and 3-year survival rates in group 1 were 73.2% and 23%, and the 1- and 3-year survival rates in group 2 were 73.3% and 0. The difference was statistically significant ( P<0.05). Univariate analysis showed that age, mGPS, CA19-9, tumor diameter, and tumor differentiation were related at the prognosis of ICC. Multivariate analysis showed that age, tumor differentiation, tumor diameter and mGPS were independent risk factors for the prognosis of ICC. Conclusion:mGPS is an independent risk factor affecting the prognosis of ICC patients.
ABSTRACT
Objective:To evaluate clinical and pathological factors related to the actual 5-year survival of patients with hilar cholangiocarcinoma (HCC).Methods:A total of 94 HCC patients who underwent radical surgery at the Department of Hepatobiliary and Pancreatic Surgery, Li Huili Hospital of Ningbo Medical Center from Jan 2000 to Jun 2015 were enrolled in this study.Patients were divided into two groups: postoperative survival group beyond 5 years and death group within 5 years. The clinical and pathological features of the two groups were analyzed.Results:Of the 94 patients, 19 (20.2%) had a postoperative survival time of more than 5 years. The actual 5-year overall survival rate of HCC patients (20.2%) was lower than that estimated by Kaplan-Meier survival analysis (22.2%). Gender, age, CEA value, CA199 value, total bilirubin, Child-Pugh classification, Bismuth classification and preoperative jaundice reduction were not significantly different between the two groups nor there were significant difference between two groups in operation time, blood loss, surgical procedure, combined caudate lobectomy, combined pancreaticoduodenectomy, combined resection of surrounding organs, vascular reconstruction and number of bile duct orifices in remnant liver surface. There were significant differences between two groups in the variables of pathological phenotype ( P=0.012), lymph node metastasis ( P=0.001) and resection level ( P=0.048). Conclusion:Non-papillary type, lymph node metastasis and R 1 resection are the independent risk factors of the actual 5-year survival.
ABSTRACT
Objective:To analyze prognostic factors of hepatocellular carcinoma (HCC) combined with portal vein tumor thrombus (PVTT) after surgical resection.Methods:The data of 98 patients with HCC combined with PVTT who underwent surgical resection in Ningbo University Affiliated Li Huili Hospital from January 2008 to June 2019 were analyzed retrospectively, including 83 males and 15 females with an average age of 53 years. The survival rate was calculated by Kaplan-Meier method and compared using log-rank test. Cox regression model was used for the multivariate analysis of the prognosis of patients.Results:The 1, 2, and 3-year overall survival rates were 75.9%, 51.5%, and 35.4%, respectively, with a median survival time of 25 months; the 1, 2, and 3-year disease-free survival rates were 35.0%, 16.1%, and 8.6%, respectively, with a median disease-free survival time of 8 months. Multivariate analysis showed that the overall survival of patients with preoperative alpha-fetoprotein (AFP) ≥400 μg/L ( HR=1.760, 95% CI: 1.079-2.873) and hepatic vein tumor thrombus (HVTT, HR=3.809, 95% CI: 1.655-8.765) was poorer after surgical resection (all P<0.05), while the survival of patients with postoperative adjuvant trans-arterial chemoembolization (TACE) ( HR=0.397, 95% CI: 0.220-0.716, P=0.002) was better. Preoperative AFP≥400 μg/L ( HR=2.339, 95% CI: 1.488-3.676) , undergoing HCC resection combined with PVTT dissection ( HR=2.038, 95% CI: 1.090-3.811), and with HVTT ( HR=2.374, 95% CI: 1.160-4.857) (all P<0.05) are independent risk factors for recurrence in patients with HCC combined with PVTT, postoperative adjuvant TACE ( HR=0.535, 95% CI: 0.307-0.933, P=0.027) is a protective factor. Conclusion:Preoperative AFP≥400 μg/L and HVTT are independent risk factors for the prognosis of patients with HCC combined with PVTT. Reasonable selection of surgical methods and postoperative adjuvant TACE may improve the prognosis of patients.
ABSTRACT
Intrahepatic cholangiocarcinoma (ICC) has a high degree malignancy, and its incidence has gradually increased in recent years. Surgery is still the only curative treatment for ICC to achieve long-term survival, but its onset is hidden, and most patients have lost the opportunity of operation when they are diagnosed. ICC shows significant heterogeneity. With the development of the second generation sequencing technology, the tumor patterns of ICC, such as DNA, RNA, epigenetic, protein, microenvironment and so on, have been gradually discovered. The purpose of this article is to review the research progress of molecular typing and clinical application of ICC in recent years.
ABSTRACT
Objective:The aims of this study were to compare the efficacy between salvage liver transplantation (sLT) and rehepatectomy (RR) basing on the propensity score matching (PSM), and to explore the prognositc factors of patients with recurrent hepatocellular carcinoma (HCC).Methods:124 patients with intrahepatic recurrence after hepatectomy in our center from January 2012 to August 2018 were divided into sLT group( n=46) and RR group( n=78). 34 patients were selected for data analysis base on 1∶1 propensity score matching (PSM). The advantages and disadvantages of the two surgical methods and the prognostic factors of the patients were discussed by comparing the basic clinical data, OS and DFS of the two groups before and after matching. Results:Before matching, the pre-operative serum total bilirubin, the occurrence of multiple tumors, the proportion of preoperative TACE and the proportion of patients within Milan criteria of the sLT group were higher than those of the RR group, and the maximum tumor diameter of the sLT group was shorter than that of the RR group ( P<0.05); the time of operation, the amount of intra-operative blood loss, the positive of MVI and the proportion of postoperative Clavien grade Ⅲ and above of RR group were higher than those of RR group ( P<0.05). After matching, the operation time, intra-operative blood loss and the proportion of postoperative complications of sLT group were higher than those of RR group; there was nosignificant difference between 1-, 3- and 5- years OS of sLT group and RR group( P>0.05), the 1-, 3- and 5-years DFS of sLT group were better than those of RR group( P<0.05); AFP≥100 μg/L was the independent risk factor of OS, and the type of operation and AFP≥100 μg/L were independent risk factors of DFS. Conclusions:The pre-operative condition of sLT group was more severe, and the operation time, intra-operative blood loss and post-operative severe complication rate of sLT group were higher than those of RR group, and the DFS time of sLT group was longer than that of RR group, but there was no significant difference in OS between the two groups.
ABSTRACT
Hepatocellular carcinoma is a common malignancy of digestive system. Tumor markers are important for the early diagnosis and prognosis of hepatocellular carcinoma. Protein induced by vitamin K absence or antagonist-Ⅱ (PIVKA-Ⅱ) is of high specificity and sensitivity in hepatocellular carcinoma diagnosis. In addition, previous studies suggested that PIVKA-Ⅱ played a role in proliferation, invasion and metastasis of hepatocellular carcinoma and could be used for prognosis of hepatocellular carcinoma. This article reviewed the recent advances in the underlying biological mechanism of PIVKA-Ⅱ in hepatocellular carcinoma and concluded the value of PIVKA-Ⅱ in hepatocellular carcinoma diagnosis and prognosis.
ABSTRACT
Objective:To study the influencing factors in predicting conversion of laparoscopic liver tumor resection to open surgery to provide references for selection of patients for laparoscopic hepatectomy.Methods:The clinical data of 222 patients who were planned to undergo laparoscopic liver tumor resection at Ningbo Medical Center Lihuili Hospital from December 2015 to November 2018 were analyzed retrospectively. There were 146 males and 76 females, with an average age of 58.1 years. These patients were divided into the conversion group ( n=24) and the laparscopic group ( n=198) according to whether intraoperative conversion to open surgery was carried out. Chi-square test was used to evaluate relevant factors of conversion. Logistic regression analysis was used for multivariate analysis and to find out independent risk factors of conversion. Results:The conversion rate was 10.8% (24/222). Univariate analysis showed that hypertension, history of abdominal surgery, liver cirrhosis, tumors located at posterosuperior segments and major liver resection were significantly associated with conversion (all P<0.05). Multivariate analysis showed that the risk factors which were independently associated with conversion were liver cirrhosis ( OR=2.611, 95% CI: 1.018-6.701), tumors located at posterosuperior segments ( OR=6.115, 95% CI: 2.207-16.941), and major liver resection ( OR=3.361, 95% CI: 1.150-9.825)(all P<0.05). Conclusion:Patients who were planned for laparoscopic liver tumor resection with liver cirrhosis, tumors at posterosuperior segments or major liver resection were at higher risks of conversion to open surgery.
ABSTRACT
Objective:To study the relationship between morphologic classification and prognosis of patients with intrahepatic cholangiocarcinoma (ICC).Methods:The clinicopathologic data of 125 ICC patients who underwent R 0 resection at the Ningbo Medical Center Li Huili Hospital from January 2011 to May 2019 were retrospectively analyzed. This cohort consisted of 67 males and 58 females, aged 26.0 to 82.0 (63.5±9.5) years old. Based on the resected specimens, the patients were divided into the mass forming type, periductal infiltrating type and mixed type. The survival rates and recurrence-free survival outcomes of the patients among the three types were compared, and the risk factors that influenced prognosis were analyzed. Results:Using the predetermined inclusion and exclusion criteria, 16 patients with missing data and other causes of death were excluded from the initial 125 patients. Also, as the number of the mixed type was small, these patients were excluded. Finally 62 patients in the mass forming type and 42 patients in the periductal infiltrating type were analyzed. In the mass forming group, there were 32 males and 30 females, aged (63.1±9.1) years. In the perivascular infiltration group, there were 22 males and 20 females, aged (64.1±10.2) years. The 1-, 3-, 5-year survival rates of the mass forming group were 78.1%, 33.2%, 18.9% (median survival 25 months). The 1-, 3-, 5-year survival rates of the periductal infiltrating type were 63.3%, 8.3%, 6.1% (median survival 15 months). There were statistically significant differences between the two groups ( P<0.05). The median recurrence-free survival for the mass forming and the periductal infiltrating groups were 18 and 11 months, respectively, with a statistically significant differences between them ( P<0.05). Univariate and multivariate analysis showed that TNM staging Ⅲ~Ⅳ ( HR=2.966, 95% CI: 1.549-5.679) and periductal infiltrating type ( HR=2.403, 95% CI: 1.236-4.670) were independent risk factors for survival of these patients after operations. TNM staging Ⅲ~Ⅳ ( HR=2.466, 95% CI: 1.325-4.589), low grade differentiation ( HR=0.528, 95% CI: 0.299-0.934) and periductal infiltrating type ( HR=2.432, 95% CI: 1.295-4.565) were independent risk factors for relapse-free survival of these patients ( P<0.05). Conclusions:Morphological classification was found to be an independent risk factor for prognosis of ICC patients in this study, with significantly worse long-term prognosis when compared with the mass forming type.
ABSTRACT
Objective:To study the impact of perioperative intestinal microecological intervention on abdominal infection after liver transplantation.Method:Fifty patients who underwent liver transplantation at the Department of Hepatobiliary Surgery, Ningbo Medical Center Lihuili Hospital from June 2017 to June 2019 were retrospectively studied. There were 34 males and 16 females. The average age was 47 years. These patients were divided into two groups using the method of non-randomized concurrent control. One group formed the perioperative intestinal microbiological intervention group, while the other group served as the conventional treatment control group. There were 25 patients in each group. The preoperative and postoperative intestinal flora and the occurrence of postoperative abdominal infection of the two groups were compared.Results:After operation in both groups, enterococci increased, enterobacteriaceae decreased, while non-fermenting bacteria and candida showed no significant changes. In the intervention group, the counts of enterobacter, enterococcus and candida were significantly lower than the control group on day 15 after operation ( P<0.05). The contents of bifidobacteria and lactobacillus in the intervention group were significantly higher than that in the control group on days 7 and 15 after operation. On the other hand, the contents of enterobacter on day 7 and enterococcus on day 15 after operation in the intervention group were significantly lower than the control group ( P<0.05). The intestinal flora of the two groups were imbalanced before liver transplantation. The ratio of bifidobacterium / enterobacteriaceae in the intervention group was significantly higher than the control group on day 7 and 15 after operation ( P<0.05). The incidence of intestinal bacterial translocation in the control group was 32.0% (8/25), with 6 patients diagnosed to have abdominal infection caused by intestinal bacterial translocation. The incidence of intestinal bacterial translocation was 8% (2/25) in the intervention group, with 1 patient diagnosed to have abdominal infection caused by intestinal bacterial translocation. The incidence of bacterial translocation in the intervention group was significantly lower than the control group ( P<0.05). There were no significant differences in the incidences in the intestinal bacterial translocation and abdominal infection between the two groups ( P>0.05). Conclusions:Probiotics intervention in the perioperative period of liver transplantation improved the imbalance of intestinal flora, reduced the incidence of intestinal bacterial translocation, and played a positive role in reducing abdominal infection after liver transplantation.
ABSTRACT
Objective@#To study the impact of intraoperative pancreatic resection margin status on prognosis in patients with pancreatic head cancer.@*Methods@#The clinical and follow-up data of 109 patients who underwent pancreaticoduodenectomy at Ningbo Lihuili Hospital from March 2012 to October 2018 were analyzed retrospectively. The association of intraoperative resection margin status and other clinicopathological factors on prognosis was analyzed by the Kaplan-Meier method and the Cox proportional hazard model. Logistic multivariate analysis was used to study factors influencing the margin status.@*Results@#Of 109 patients, 20 had a positive intraoperative resection margin, and 89 had a negative margin. Postoperative pathological examination showed that all the patients had a negative surgical margin. Univariate analysis suggested that CA19-9 before operation, preoperative adjuvant chemotherapy, intraoperative pancreatic resection margin status, maximum diameter of tumor, perineural invasion, lymphovascular invasion, tumor differentiation, and N staging were significantly related to survival in the entire cohort (all P<0.05). Multivariate analysis showed CA19-9 ≥37 IU/ml, perineural invasion, lymph node metastasis, tumor diameter ≥4 cm and poor tumor differentiation were independent risk factors of bad prognosis (P<0.05). Univariate analysis of prognosis showed significant differences in lifetime prognosis between the positive margin group and the negative group (median survival time: 11 months vs. 21 months, P<0.05), but a positive resection margin was not an independent risk factor on prognosis (P>0.05). Analysis of the clinicopathological factors between the two groups showed that in the positive pancreatic neck margin group, the distribution of adverse pathologic factors like low tumor differentiation, tumor diameter ≥4 cm, perineural invasion and lymphovascular invasion were significantly different compared with the negative group (P<0.05). Tumor diameter ≥4 cm (OR=5.72, 95%CI: 1.60~20.49) and low tumor differentiation (OR=3.79, 95%CI: 1.20~11.95) were independent influencing factors of positive margin on logistic multivariate analysis.@*Conclusions@#Intraoperative pancreatic positive margin was not an independent risk factor of prognosis, but it was meaningful in predicting survival. Presence of positive margins was often combined with existence of some adverse pathological features, such as large tumor diameter and low tumor differentiation. Prognosis of patients with a positive margin was often poor. A positive pancreatic margin was an intraoperative marker of poor tumor biology in patients with pancreatic ductal adenocarcinoma.
ABSTRACT
Objective@#To explore the predictive significance of logarithm of lymph node positive number to lymph node negative number (LODDS) in patients with gallbladder cancer, and to establish a predictive model of gallbladder cancer based on LODDS.@*Methods@#The clinical data of 1321 gallbladder cancer patients who underwent lymphadenectomy in SEER database from 2010 to 2014 were collected. They were randomly divided into test group (n=793) and verification group (n=528). COX multivariate analysis was used to determine independent prognostic factor, and a Nomogram prediction model was established. C index was used to evaluate the accuracy of patient Nomogram and TNM. ROC curve was used to evaluate the accuracy of the contour map and TNM staging in predicting survival rates.@*Results@#Independent risk factors for COX analysis were selected including age, tumor size, grade, TNM stage and LODDS analysis, and the contour map was drawn. In the experimental group, the C index was 0.744 (95% CI, 0.707-0.781), and the AUC values of ROC curves predicting 3-year and 5-year survival were 0.815 and 0.823, respectively. The predictive value of C index for TNM staging in the test group was 0.699 (95% CI, 0.662-0.736), and the AUC value of ROC curve for TNM staging predicting 3-year and 5-year survival was 0.779 and 0.790, respectively.@*Conclusion@#LODDS is an independent prognostic factor for gallbladder cancer. The prediction model based on LODDS is more accurate than TNM staging.
ABSTRACT
The incidence of intrahepatic cholangiocarcinoma (ICC) has been increasing year by year. For most patients, surgical resection is not suitable when they are diagnosed as ICC. Conventional chemotherapy and radiotherapy are not effective for the long-term survival rate of ICC patients and lead to the poor overall prognosis. In recent years, with the deepening understanding about the molecular mechanism of biliary malignant tumors, some key genes and signaling pathways related to the pathogenesis of ICC have been identified, providing new ideas for the targeted therapy. In this paper, major molecular mechanisms and targeted therapies of ICC are reviewed.
