RESUMO
Multidisciplinary comprehensive treatment is the best medical model for liver cancer at present, and combined local and systemic treatment can prolong the survival period and improve the quality of life of patients. Local thermal ablation therapy represented by radiofrequency ablation has the advantages of precision and minimally invasive, easy operation, and precise efficacy, and has been increasingly widely used in the clinical application of hepatocellular carcinoma treatment. Radiofrequency ablation, as a precise and minimally invasive local thermal ablation therapy, can increase the efficacy, reduce the occurrence of complications of patients by combining with systemic therapies, such as surgery, interventional therapy, chemotherapy and targeted therapy. In this paper, the clinical application progress of radiofrequency ablation in hepatocellular carcinoma treatment is reviewed, and the combined therapeutic program of radiofrequency ablation in hepatocellular carcinoma in the era of multidisciplinary comprehensive treatment is discussed. For patients with advanced hepatocellular carcinoma, radiofrequency ablation combined with chemotherapy, targeted therapy and immunotherapy has shown good effects in the treatment, which is expected to bring more benefits to patients with advanced hepatocellular carcinoma in the future.
RESUMO
Objective:To explore the pathogenesis of gallbladder cholesteryl polyps (GCP) and gallbladder cholesterol calculus (GCC) by studying the different changes of mucin (MUC) expression and reverse cholesterol transporter (RCT) in gallbladder mucosa epithelium.Methods:The data of 10 GCP patients (GCP group), 10 GCC patients (GCC group) and 5 patients with normal gallbladder resection (control group) were retrospectively analyzed, who underwent cholecystectomy in the Department of General Surgery, Xuanwu Hospital, Capital Medical University from January to December 2021. Among the 10 patients in the GCP group, there were 5 males and 5 females, aged (43.40±9.59) years old. Among the 10 patients in the GCC group, 5 males and 5 female, aged (45.00±8.13) years old. Among the 5 patients in the control group, there were 3 males and 2 females, aged (43.80±6.01) years old. Immunohistochemical analysis was used to investigate the expression differences of various subtypes of MUC and RCT [ATP binding cassette transporter G1 (ABCG1) and B group type I scavenger receptor (SR-BI)] among each group.Results:Compared with the control group, the expression of MUC1 (3.40±0.70 vs. 0), MUC5AC (1.50±0.53 vs. 0), MUC6 (4.70±0.48 vs. 0), and ABCG1 (3.50±0.53 vs. 1.60±0.55) in the gallbladder mucosa of the GCP group increased, while the expression score of SR-BI decreased (1.70±0.48 vs. 3.40±0.55), with statistical significance (all P<0.001). Compared with the control group, the expression of MUC1 (4.80±0.42 vs. 0), MUC5AC (4.70±0.48 vs. 0), MUC6 (3.30±0.67 vs. 0), and ABCG1 (3.40±0.52 vs. 1.60±0.55) in the gallbladder mucosa of the GCC group increased, while the expression score of SR-BI decreased (0 vs. 3.40±0.55), with statistically significant differences (all P<0.001). Conclusion:The different expression levels of MUC1, MUC5AC, MUC6, and RCT proteins lead to the differential formation of GCP and GCC on the basis of the co-pathogenesis in high cholesterol in bile.
RESUMO
Cholecystolithiasis is a common clinical disease, which can be secondary to cholecystitis, cholangitis, pancreatitis and gallbladder cancer. Many patients with gallstone have no obvious clinical symptoms such as biliary colic. Some patients are indeed asymptomatic because there are not obstruction and inflammation. However, some patients have no symptoms due to ignorance, mistaken for stomach pain, enteritis, etc. Some patients have no symptoms because of insensitivity and insufficient perception. For other patients with abnormal gallbladder morphology and structure, non-functional gallbladder must be no pain. To clarify the concept, diagnosis and classification of asymptomatic gallstones according to pathophysiological stages is conducive to the development of personalized management strategies. According to guidelines formulated by different periods, different regions and different medical institutions, there are many controversies regarding the management of asymptomatic gallstones, including regular follow-up, drug treatment, surgical resection or gallblades-saving lithotomy. Reasonable personalized diagnosis and treatment requires more in-depth basic research evidence.
RESUMO
Gallstone is a common and frequent disease and frequent incidence, secondary infection and cancer seriously affect the health of patients. Academic organizations in different regions have issued multiple guidelines and consensus to promote the normative diagnosis and treatment of gallstones. However, in clinical practice, most symptomatic gallstones are treated, while the formation and prevention process of gallstones are ignored, making the concept of treating without a disease has not been strengthened.This article reviews the risk factors and mechanisms of gallstone formation, and points out the importance of effective prevention during stone formation. In the stage of gallstone formation, the high risk factors of stone formation can be analyzed through two aspects of injury factors and protective factors, and the high risk groups of stone formation can be screened out. According to the pathophysiological progression of gallstones, personalized prevention and follow-up strategies can be developed for the stone formation stage of gallstones.
RESUMO
Gallstones and acute calculous cholecystitis are common diseases in surgery. China has entered an aging society. Elderly patients are a high incidence group of gallstones and acute calculous cholecystitis. Their surgical diagnosis and treatment strategies need to be formulated individually, and reasonable diagnosis and treatment methods should be comprehensively selected according to the patient′s condition and the medical level of the medical institution. For those who are in good physical condition and can tolerate the operation, it is recommended to give priority to surgical treatment, and the minimally invasive surgery mainly suitable for laparoscopic cholecystectomy (LC) is preferred. Open surgery is more appropriate for complicated conditions or patients whose general conditions are not suitable for laparoscopic surgery. Other minimally invasive treatment measures can be applied at the same time. For patients who can not tolerate surgical treatment, puncture, endoscopy, intervention and other means can be selected, combined with drugs for conservative treatment, so as to obtain the opportunity of surgical treatment or improve the prognosis. In this paper, the latest research literature at home and abroad has been collected to review and summarize the latest research progress in the physiology and aging characteristics of the biliary tract in the elderly, the diagnosis and treatment of gallstones and acute calculous cholecystitis. It is hoped that this paper can provide reference for the clinical diagnosis and treatment of such diseases, and think and prospect the future research.
RESUMO
Objective:To compare the efficacy and safety of providing nasogastric (NG), nasojejunal (NJ), and parenteral nutrition (PN) support to pancreatitis patients who were intolerant to oral feeding.Methods:One hundred pancreatitis patients who were intolerant to oral feeding treated at the Xuanwu Hospital of the Capital Medical University from October 2018 to September 2020 were retrospectively studied. They were divided into three groups based on the nutritional support given to them: the NG group, NJ group, and PN group. The acute physiology and chronic health evaluation Ⅱ(APACHEⅡ), nutritional risk screening 2002 (NRS2002), hemoglobin, albumin, pre-albumin and other clinical data were recorded and compared among the three groups.Results:After nutrition support treatments, the hemoglobin, albumin and pre-albumin levels were significantly better than before giving nutrition support, and the APACHE Ⅱ scores were significantly improved in all the groups. The NRS2002 scores were significantly better in the NJ group ( Z=2.28, P=0.023) and the NG group ( Z=1.99, P=0.046). With compared to the PN group, the albumin and pre-albumin levels were significantly higher in the NG and NJ groups, and the NRS2002 score after giving nutrition support treatment was significantly lower ( P<0.05). Compared with the PN group, the APACHE Ⅱ score ( t=2.18) and the hemoglobin levels ( t=2.04) were significantly better in the NJ group ( P<0.05). The overall incidence of complications in the NJ group was 41.2% (14/34), which was significantly lower than the NG group [78.8%(26/33), χ 2=5.41, P=0.020] and the PN group [66.7% (22/33), χ 2=4.35, P=0.037]. Conclusion:Enteral nutrition support through NG and NJ are better than PN in acute pancreatitis patients who were intolerant to oral feeding.
RESUMO
Objective:To investigate the causes and prognosis of salvage cholecystectomy for relapsing cholecystolithiasis after gallbladder-preserving gall stones removal surgery.Methods:From Jul 2015 to Dec 2019, 24 referral patients with gallstone recurrence after gallbladder-preserving cholelithotomy surgery received salvage cholecystectomy. The clinical data was analyzed to explore the causes for re-operation and the prognosis.Results:Twenty-two cases had definite gallstone recurrence, among them 19 cases were symptomatic, 2 cases were operated on suspected gallbladder tumor and common bile duct stones induced acute cholangitis. Laparoscopic cholecystectomy was successfully performed in 23 cases and 1 case was converted to open surgery. No severe complication were observed in all the patients.Conclusions:Symptomatic gallstone recurrence is the most common causes of salvage cholecystectomy after gallbladder-preserving cholelithotomy. Laparoscopic surgery procedure is still highly successful.
RESUMO
Gallbladder cancer is a highly malignant tumor of the digestive tract with a poor prognosis. Currently, only radical surgical resection can achieve good results. As an important part of tumor adjuvant treatment and palliative treatment, radiotherapy has been widely used in the treatment of various malignant tumors and achieved certain effect. This article mainly reviews advances of radiotherapy in gallbladder cancer from four aspects: postoperative radiotherapy, preoperative neoadjuvant radiotherapy, intraoperative radiotherapy and palliative radiotherapy for gallbladder cancer.
RESUMO
The Tokyo guidelines (TG) for acute cholecystitis, published in 2007, have been updated to the third edition of TG18, and the European World Association of Emergency Surgeons (WSES) Guidelines, published in 2016, has also been updated to the 2020 edition. Different guidelines have certain consensus and differences in diagnosis and treatment ideas. Better understanding the updated content in the guidelines and master the consensus among different guidelines can make the clinical diagnosis and treatment more standardized, safer and scientific. In this paper, the changes in the updating process of each version of the two guidelines and the consensus differences between the guidelines are summarized in order to provide a clear idea for clinical workers in the diagnosis and treatment of acute cholecystitis.
RESUMO
To perform Meta-analysis to identify risk factors associated with gallbladder polyps (GBP) formation in east Asian population. Three English electronic bibliographic databases includes PubMed, Embase and Medline, with reviewed researches from 1986 to 2017. All possible risk factors of GBP formation were recorded. Meta-analyses were performed by Review Manager Software. Pooled odds ratios (OR) or the mean difference (MD) were used to determine risk factors. Sixteen studies and 227021 people were recruited, including 17261 people with GBP and 209760 without GBP. For categorical variables evaluated by OR test., risk factors of GBP formation were male gender (OR, 1.63; 95%CI, 1.42-1.87) and positive HBsAg. GBP formation were not correlated with age <50 years old, hypertension, DM, BMI ≥ 25kg/m2, smoking, drinking, HDL decrease, TC increase, TG increase, fatty liver and GBS. For continuous variables evaluated by MD test, risk factors of GBP formation were DBP (MD, 1.08; 95%CI, 0.15-2.02), mean BMI (MD,0.19; 95%CI,0.02-0.35), waist circumference (MD,1.780; 95%CI, 0.17,3.40), mean LDL (MD,0.89; 95%CI,0.03-1.75), mean HDL (MD,-1.87; 95%CI,-3.21 to -0.52). GBP formation were not correlated with mean age, SBP, mean TC, mean TG, ASL and ALT. In conclusion, risk factors of gallbladder polyp formation included male gender, higher BMI, higher waist circumference, higher DBP, higher LDL, lower HDL and positive HBsAg in east Asian population. GBP formation was not correlated with age, hypertension, DM, smoking, drinking, fatty liver, GBS, TC, TG, SBP, ASL and ALT. The mechanism of Dyslipidemias causing GBP needs deeper study in future.

OBJECTIVE: Aim to explore the association of dyslipidemias with GBP prevalence, number and size in a large Chinese population in Beijing. Dyslipidemias include hypercholesterolemia, hypertriglyceridemia, increased low density lipoprotein (LDL) and decreased high density lipoproteins (HDL). METHODS: Prevalence of GBP and its association with dyslipidemias were retrospectively investigated among subjects who underwent check-up at Health Screening Center of Xuanwu Hospital between January 2014 and December 2017. RESULTS: This study enrolled 97117 participants. Prevalence of GBP was 7.3%. There were significant differences in increased LDL (595/7107 vs 6004/90010, P = 0.000) and increased cholesterol (TC) (403/7107 vs 4846/90010,P = 0.000) between GBP group and control group, but not in decreased HDL and increased triglyceride (TG). Logistic regression analysis showed that gender, age, BMI, SBP, DBP and LDL were independently associated with GBP. People with increases LDL had 1.488 times higher risk for GBP formation. Trend of dyslipidemias prevalence change according to age was similar with that of GBP. Increased LDL group had higher GBP prevalence rate (9.0% vs 7.2%, p = 0.000), multiple GBP proportion (2.9% vs 2.2%, p = 0.000) and large polyps with diameter ≥ 5 mm proportion (3.7% vs 2.6%,p = 0.000). Comparing with control group, there was higher proportion of large polyps in Increased TC group (3.2% vs 2.7%, p = 0.019) and decreased HDL group (3.0% vs 2.6%,p = 0.028). Increased TG group had not difference with its control group in GBP prevalence, number or size. CONCLUSION: Dyslipidemias is associated with GBP formation. Dyslipidemias change according to age is consistent with GBP prevalence. Increased LDL was a more related risk factor rather than decreased HDL, increased TC or TG.

RESUMO
Acute appendicitis is one of the most common acute abdominal diseases in surgery. Due to its urgent onset and rapid progress, timely diagnosis and early treatment are beneficial to the prognosis of patients. The diagnosis of acute appendicitis should be based on the characteristics of different populations, based on clinical symptoms, physical examination, laboratory examination, and imaging methods. Anti-infection treatment should be started as soon as possible in the early stage, and antibiotics should choose effective drug treatment with both anaerobic bacteria and aerobic bacterial infection. Appendectomy is still the most effective treatment for acute appendicitis. In the case of uncomplicated abdominal infection such as simple and non-perforated appendicitis, antibiotic treatment may be chosen, but the development needs to be closely observed. Laparoscopic appendectomy is the first choice, but in pregnancy patients should be cautious. Emergency surgery is required for acute perforated appendicitis and attention should be paid to intraoperative abdominal flushing. Immediate surgical treatment of appendiceal abscess may involve the risk of partial ileectomy. Antibiotic treatment is recommended, with percutaneous abscess puncture and drainage if necessary.

RESUMO
Objective:To study the occurrence and disappearance of gallbladder polyps in patients who underwent multiple ultrasonographic examinations, and to determine the risk factors of formation of gallbladder polyps.Methods:From January 2014 to December 2017, relevant data on patients who underwent follow-up abdominal ultrasound examinations at the Health Screening Center of Xuanwu Hospital was retrospectively analyzed, and the dynamic changes of gallbladder polyps were assessed. A comparative analysis was then conducted between those who had gallbladder polyps (the gallbladder polyps group, n=1 149) and those who had no gallbladder polyps (the control group, n=18 243). The occurrence, changes and disappearance of gallbladder polyps shown on multiple untrasonographic examinations were compared. Results:The patterns of changes of gallbladder polyps showed that the proportions of patients with gallbladder polyps which were stable in size ( n=1 149, 52.1%) were greater than those who had new appearance of gallbladder polyps ( n=797, 36.2%), and these 2 groups of patients were having higher proportions than those who had disappearance of gallbladder polyps ( n=258, 11.7%). The largest proportion of gallbladder polyps were found in middle-aged people, and new polyps were mainly found in the age group of 30.0-59.0 years. The peak of gallbladder polyps incidence was after age 60. There were significant differences in age, male, blood glucose, total cholesterol, low density lipoprotein (LDL), and diastolic blood pressure between the study and the control groups (all P<0.05). Multivariate analysis showed that age ( OR=1.152), male ( OR=1.407) and LDL ( OR=1.656) were independent risk factors of gallbladder polyp formation. Conclusions:The annual incidence of gallbladder polyps was 9.7‰. Gallbladder polyps were more commonly found in middle age, and the incidence of gallbladder polyps was increasing. Gallbladder polyps could disappear. However, with increase in initial diameter of gallbladder polyps, the probability of disappearance decreased. Age, male gender and elevated LDL were independent risk factors of gallbladder polyps formation.
RESUMO
Type 2 diabetes mellitus (T2DM) is a health problem in the world,patients are often accompanied by obesity.The experimental animal design of bariatric surgery is helpful for the development of less invasive operation method,higher safety in the treatment of T2DM and newdrugs for blood glucose control.This article will review the literatures in recent years which about bariatric surgery,and provide reference for animal experiment design,to introduce the experimental animal design of bariatric surgery for the treatment of T2DM and the mechanism of blood glucose balance after the surgery.
RESUMO
Objective@#To explore the selection method and technology of laparoscopic surgery for gallbladder stones and common bile duct stones(GCBDS).@*Methods@#Data was collected from 318 in-patients of GCBDS at Department of General Surgery,Xuanwu Hospital of Capital Medical University from January 2013 to December 2017, and 298 in-patients acceptedlaparoscopic cholecystectomy(LC) and choledocholithotomy were recruited into final analysis.There were 138 males and 160 females,aged (60.4±18.6)years (range:25-89 years).Retrospective analysis was done on method distribution,effect and safety of laproscopic surgery.Comparisons of basic characters and therapeutic effects were performed betweenlaparoscopic common bile duct exploration (LCBDE) combined with primary closure and T tube drainage(TTD).@*Results@#Among therecruited in-patients,LC combined with common bile duct exploration was performed in 7 cases(2.3%, 7/298), LC combined with LCBDE was performed in 291 cases(97.7%,291/298).There were 133 cases (45.7%,133/291) who treated by LCBDE combined with TTD and 158 cases(54.3%,158/291) who treated by LCBDE combined with primary closure.In LCBDE combined with primary closure group,18 cases (11.4%,18/158)had intraoperative biliary manometry.All patients were followed up for 6 months at least and there no death.Postoperative complications rate was 10.0% (29/291).There were no significant differences in sex ratio,age,American Society of Anesthesiologists score,concomitant diseases and previous abdominal surgery history between LCBDE combined with primary closure and LCBDE combined with TTD group.Patients in LCBDE combined with primary closure group were accompanied with less acute cholangitis than TTD group (43.3% vs.76.7%; χ2=9.061, P=0.002).There were no significant differences in the diameter of common bile duct, the number of stones, hospitalization expenses and the incidence of complications between the two groups(all P>0.05).LCBDE combined with primary closure had shorter operation time ((134.2±28.3)minutes vs.(148.3±19.6)minutes; t=-1.830, P=0.011)and post-operative hospitalization time ((5.6±2.6)days vs. (7.2±2.4)days; t=-1.847,P=0.014).Bile duct leakage rate was higher in primary closure group(6.3% vs.0.8%, χ2=3.934, P=0.047) and TTD group had higher residual stones rate(6.8% vs.1.3%; χ2=6.008, P=0.014).@*Conclusion@#Strategy for treating GCBDS by laparoscopic surgery should be considered preoperative evaluation and intraoperative exploration to select appropriate minimally invasive surgical methods and techniques.
RESUMO
To design teaching course of problem-based learning (PBL) combined with case-based learning (CBL) for standardized training of clinicians based on clinical decision thinking mode (CDTM) of diagnosis and treatment process for primary liver cancer. The CDTM of treatment choice for primary liver cancer is multi-scheme selection model. The general decision rule includes decision condition, action plan and decision tree. For the theoretical study of clinical decision rules, it is suitable to design PBL teaching, but it is suitable to design CBL teaching course for clinical decision-making practice. The teaching course of PBL combined with CBL is conducive to improving the ability of clinicians' clinical decision thinking step by step.
RESUMO
Objective To compare the clinical efficacy of primary closure versus T-tube drainage after laparoscopic common bile duct exploration in acute cholangitis cases.Methods The clinical data of 100 patients with acute cholangitis undergoing laparoscopic common bile duct exploration from January 2012 to December 2014 were reviewed.54patients received primary closure of the common bile duct and 46 patients were subjected to T-tube drainage after choledochotomy.Results One hundred patients underwent the surgery successfully.Compared with the T-tube group,the operation time(96.72 min vs 123.00 min,P =0.001),intraoperative blood loss(27.13 ml vs 38.48 ml,P =0.009),postoperative gastrointestinal function recovery time(1.57 d vs 2.33 d,P=0.003) and postoperative hospital stay(6.19 d vs 9.20 d,P=0.000) were significantly less in the primary closure group.There were no statistical differences in the incidence of postoperative drainage (309.22 ml vs 212.46 ml,P =0.070),drainage time (3.96 d vs 4.02 d,P =0.875),incidence of bile leakage(9.3% vs 0,P =0.060) and postoperative bleeding rate(5.1% vs 2.2%,P =0.622) between these two groups.Conclusion Laparoscopic common bile duct exploration with primary closure of the common bile duct is an effective and safe procedure in acute cholangitis cases compared with T-tube drainage.
RESUMO
Hyperlipidemic pancreatitis (HLP) has an increasing incidence.Primary HLP is common in patients with familial difficiency of lipoprotion lipase or apo-C Ⅱ.While for secondary HLP,the common reasons are excessive drinking,diabetes,obesity,fat-rich diet and special medications.Lipidlowering drugs,plasma exchange (PE) or continuous veno-venous hemofiltration (CVVH),low molecular heparin as well as insulin,have been widely used for the treatment of HLP.Changing of diet and lifestyle,in addition to controlling risk factors are the keys to preventing HLP.This article summarizes the latest perspectives and research progress of HLP.
