ObjectiveTo investigate the effect of combined or non-combined liver resection for T2a gallbladder cancer. MethodsAccording to the established inclusion and exclusion criteria, the patients with T2a gallbladder cancer admitted to Peking Union Medical College Hospital from January 2016 to December 2021 were retrospectively collected, then were assigned into combined with liver resection group and non-combined with liver resection group. The general characteristics, perioperative information, and prognosis of the two groups were compared. ResultsA total of 58 patients were enrolled in this study, including 23 males and 35 females; aged (64.8±11.1) years. There were 43 cases in the combined with liver resection group and 15 cases in the non-combined with liver resection group. There were no statistic differences in the demographic data, lifestyle, onset symptoms, preoperative combined diseases, and preoperative tumor markers between the two groups (P>0.05). Compared with the combined with liver resection group, the proportion of patients received bile duct resection was higher (P=0.013) and the operation time was shorter (P=0.045) in the non-combined with liver resection group. There were no statistic differences in the other perioperative informations between the two groups (P>0.05). A total of 12 patients had postoperative complications, including 3 cases of grade Ⅰ, 8 cases of grade Ⅱ, and 1 case of grade Ⅲa by Clavien-Dindo classification. All patients improved after treatment and were discharged smoothly. No patient was readmitted within 30 d after discharge. All 58 patients were followed up with a median follow up time of 29 months. During the follow-up period, there were 47 cases (81.0%) of tumor-free survival, 2 cases (3.4%) of survival with tumor, and 9 cases (15.5%) of death. There were no statistic differences in the overall survival and disease-free survival between the two groups by log-rank test (χ2=3.418, P=0.064; χ2=1.543, P=0.214). ConclusionFromthe results of this study, for T2a gallbladder cancer, liver resection would not result in increased complications or longer hospital stay, but don’t obviously improve prognosis.
Objective To study the association and the effect of the expression of p16 and p53 protein on the occurence and development of gallbladder carcinoma. Methods The expression of p16 and p53 protein were detected in 40 cases of gallbladder carcinoma with immunohistochemical method. Results The expressions of p16 and p53 protein were closely correlated to the tumor pathological grade, lymph mode metastasis and prognosis. p16 protein was correlated to the Nevin classifications. Conclusion The results indicate that the low expression rate of p16 protein occurred in the advanced stage of gallbladder carcinoma. The expression of p16 and p53 protein are helpful in judging the malignant degree and prognosis of primary gallbladder cancer.
ObjectivesTo systematically review the incidence of various outcomes in non-visualization of the fetal gallbladder (NVFGB) fetuses by prenatal ultrasonography.MethodsPubMed, The Cochrane Library, Elsevier, ClinicalKey, CBM, CNKI and WanFang Data databases were electronically searched to collect studies on NVFGB fetuses by prenatal ultrasonography from January 1990 to March 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Then, meta-analysis was performed by using R 3.5.2 software.ResultsA total of 9 studies were included. The results of meta-analysis showed that: the incidence of fetal biliary atresia was 1.0%, with 2.0% in the isolated and 3.0% in the non-isolated. The incidence of cystic fibrosis was 6.0%, with 2.0% in the isolated and 9.0% in the non-isolated. The incidence of chromosomal abnormality was 5.0%, and 31.0% in non-isolated. The incidence of other malformations other than those described above was 13.0%, with 44.0% in the non-isolated. The incidence of gallbladder agenesis or absent gallbladder was 22.0%, with 28.0% in the isolated. The incidence of later visualization of gallbladder and normal fetal outcomes was 53.0%, with 63.0% in the isolated.ConclusionsCurrent evidence shows that most non-visualization of the fetal gallbladder can identify the presence of gallbladder during late gestation or neonatal ultrasonography. The exactly isolated non-visualization of the fetal gallbladder is highly related to the fetal gallbladder agenesis or the absence of the gallbladder. The non-isolated non-visualization of the fetal gallbladder is highly related to biliary atresia, cystic fibrosis (particularly in the presence of fetal bowel echogenicity), and chromosomal abnormalities (especially chromosome aneuploidy).
ObjectiveTo discuss the relationship between angiogenesis and the clinical pathological characteristics,
prognosis in primary gallbladder carcinoma (PGC ). MethodsThe specimens of 42 patients with PGC who underwent operation
during 1993 and 1996 were collected. The immunohistochemical staining was performed in these specimens through SABC manner.
Angiogenesis was represented by intratumor microvessel count (MVC ) and expression of vascular endothelial growth factor
(VEGF ).ResultsIn all the patients, the average MVC was 70.4±20.7, and the VEGF positive expression rate was 69.0%. The
mean MVC was 57.9±15.4 in the tumor of histograde Ⅰ and Ⅱ, and was 88.8±11.5 in another group of grade Ⅲ and Ⅳ
respectively. The mean MVC was 45.0±17.0 in the cases of Nevin stage Ⅰ, Ⅱ and Ⅲ, and was 77.2±16.0 in the other cases
of Nevin stage Ⅳ and Ⅴ. There were significant differences between two groups. VEGF expression positive rate was correlated
with grade and stage, in the patients with poordifferentiated grade and late stage the MVC was significant higher. The
expression of VEGF was markedly correlated with MVC. The 3year survival rate was significant lower in the group of high MVC
or VEGF positive expression. Conclusion Manifold VEGF secretion in PGC may increase the MVC value, and accelerate the tumor
advance and metastasis. Angiogenesis may be considered as an effective predictor to the prognosis of the primary gallbladder
carcinoma.
ObjectiveTo evaluate and analyze the clinical effect of ambulatory surgery applied to laparoscopic cholecystectomy (LC).MethodsThe patients who underwent LC in the First Affiliated Hospital of Xinjiang Medical University from June 2017 to February 2019 were collected, then were assigned to ambulatory surgery applied to LC group (ALC group) and conventional LC group (CLC group) according to the admission process mode. The patients in the ALC group received LC in the ambulatory ward and the patients in the CLC group received LC in the conventional ward. The preoperative waiting time, postoperative gastrointestinal recovery time, postoperative 6 h pain score, total hospitalization time, total hospitalization cost, patient satisfaction, and postoperative complications were compared between the two groups.ResultsA total of 433 patients underwent LC were included in this study, including 176 patients in the ALC group and 257 patients in the CLC group. There were no significant differences in the age, gender, type of gallbladder diseases, etc. between the two groups (P>0.05) except body mass index (P<0.05). There was no perioperative death in the two groups. One patient converted to laparotomy in the CLC group. Compared with the CLC group, the preoperative waiting time, postoperative gastrointestinal recovery time, and the total hospitalization time were shorter, the postoperative pain score was lower, the total hospitalization cost was less, and the satisfaction rate of patients was higher in the ALC group (P<0.05). There was 1 case of incision infection and 1 case of ascites in the operation area in the ALC group and CLC group, 1 case of fever in the ALC group and 3 cases of fever in the CLC group, respectively. There was no difference in the overall incidence of complications between the two groups (P>0.05). During the follow-up of 6 to 26 months, there was no readmission in both groups.ConclusionPatients who undergone LC based on ambulatory surgery mode recover quickly, and hospitalization cost is less, satisfaction rate is higher.
【Abstract】Objective To explore the relationship between the expression of MDR1 gene in liver cell and the formation of cholesterol calculus in gallbladder.Methods The mRNA expression level of MDR1 gene in liver cell of the cholesterol calculus group and the normal control group were measured through reverse transcriptionpolymerase chain reaction (RT-PCR)， and microglobulin β2 was used as internal contrast.Results The MDR1 mRNA expression level of the cholesterol calculus group was lower than that of the normal control group(1.30±0.19 vs 2.25±0.28, P＜0.01). Conclusion The formation of cholesterol calculus in gallbladder is related to the reducd expression level of MDR1 gene in liver cell.
We reviewed the clinical studies on drug therapy for gallbladder cancer and expounded on the current situation of conversion therapy for gallbladder cancer. Gallbladder cancer was usually diagnosed late, with high malignancy, low surgical resection rate, and poor prognosis. With the development of conversion therapy, systemic therapy combined with radical resection had effectively improved the surgical resection rate and prognosis of gallbladder cancer patients. At present, most of the published conversion therapies for gallbladder cancer were mainly retrospective researches, lacking large multicenter prospective research, and the treatment plan was still based on chemotherapy, lacking the research of targeted therapy in combination with immunotherapy. It is expected that more high-quality clinical trials can be made first-line recommendations for the conversion therapy of gallbladder cancer.
ObjectiveTo study the relationship among cholecystectomy/gallbladder disease and bile reflux gastritis.MethodsA retrospective collection of 123 patients with bile reflux gastritis who were diagnosed as outpatients and hospitalized from January 2014 to February 2019 in Shengjing Hospital Affiliated to China Medical University, and 221 patients with non-biliary reflux gastritis at the same period were collected. According to the gallbladder status, the patients were divided into three groups: gallbladder disease, cholecystectomy, and gallbladder disease-free group. The relationship between gallbladder status and bile reflux gastritis was analyzed.ResultsAmong 123 patients with bile reflux gastritis, there were 22 cases (17.89%) with cholecystectomy and 26 cases (21.14%) with gallbladder disease; 221 cases of non-biliary reflux gastritis with cholecystectomy in 7 cases (3.17%) and gallbladder disease in 30 cases (13.57%). Univariate analysis showed that the gallbladder status was different between the bile reflux gastritis group and the non-biliary reflux gastritis group (χ2=21.089, P<0.001). The study showed that the gallbladder status was related to the occurrence of bile reflux gastritis. In contrast, patients with cholecystectomy and gallbladder disease had a higher risk of occurrence than those with no gallbladder disease (OR>1, P<0.012 5). Independent risk factors were considered by logistic multivariate regression analysis, including cholecystectomy, gallbladder disease, and age (P<0.05).ConclusionsThere is a correlation between cholecystectomy/gallbladder disease and bile reflux gastritis. Cholecystectomy and gallbladder disease may be the independent risk factors for bile reflux gastritis.
ObjectiveTo introduce the current study of the metastatic mode and operation methods in advanced gallbladder carcinoma. MethodsThe literatures about metastatic mode and operation methods of advanced gallbladder carcinoma in recent 5 years were reviewed.ResultsLymph node and hepatic invasion were the main mode of advanced gallbladder carcinoma. The Japanese Society of Biliary Surgery （JSBS） classification to gallbladder carcinoma was more reasonable than the UICC classification. The survival rate after radical resection was higher than that after cholecytectomy in patients with T2n1-2M0. In the patients that tumor extended adjacent organs but the lymph node metastatic localized within n2, extended radical resection provided a survival advantage. If the patients’ tumor was not resectable or who had lymph node metastasis beyond n3, the benefit of extended radical resection seemed limited.ConclusionIn the carefully selected patients, extended radical resection will improve the prognosis of advanced gallbladder carcinoma.
