ELS could be summarized into three major categories, namely, ex-situ liver resection and autotransplantation(ELRA), ante-situm liver resection and autotransplantation(ALRA) and auxiliary partial liver autotransplantation(APLA). The successful development of ELS during the past 37 years is definitely inseparable from continuous effort s done by Chinese surgeons and researchers. Especially, the precision liver surgery paradigm has allowed to transform ELS into a modularized, more simplified, and standardized surgery, to upgrade surgical skills, to improve peri-operative outcome and long-term survival, to increase the capability of surgeons to select more complex diseases and to expand the level of medical service to the population. This review highlights the Chinese contributions to the field of ELS, focusing thereby on features of different surgical types, technical innovations, disease selection and surgical indication, patient prognosis and future perspectives.展开更多

The purpose of this study was to investigate the incidence and nature of postoperative jaundice in patients undergoing cardiac operation,to analyze the determinants,and to identify the clinical significance of this complication with regard to the associated morbidity and mortality. METHODS:A prospective observational study was made during the period of 2003-2004 in a Surgical Intensive Care Unit of a Cardiac Surgery Center,Athens. One hundred twenty-eight adult patients for open heart surgery were divided into three groups. Group A included 50 patients who underwent coronary artery bypass crafting(CABG),group B 31 patients who were subjected to aortic valve replacement(AVR)+CABG and group C 47 patients who underwent mitral valve replacement(MVR)+CABG. Aminotransferases,alkaline phosphatase,gamma-glutamyl-transpeptidase and both types of bilirubin were determined at admission,24 hours after the operation and thereafter according to clinical evolution. The presence of jaundice was associated with elevated serum bilirubin above 3 mg/dl. RESULTS:Hyperbilirubinemia developed in 34 patients(26.5%). The incidence of postoperative jaundice was higher in patients who were subjected to MVR+CABG than to CABG and AVR+CABG. Hyperbilirubinemia was correlated with prolonged cardiopulmonary by-passtime(P<0.001),aortic cross-clamping time(P<0.001),the use of intra aortic balloon pumping(P<0.001),the administration of inotrops and the number of blood and plasma transfusions. Postoperative jaundice resulted mainly from an increase in conjugated bilirubin. CONCLUSIONS:Although hyperbilirubinemia seems to be multifactorial,the type of operation,the preoperative hepatic dysfunction due to advanced heart failure(NYHA Ⅱ-Ⅲ) and the decreased hepatic flow during the operation seem to determine the incidence of jaundice.展开更多

文摘Background:The high recurrent rate after surgery hinders the survival of patients with hepatocellular carcinoma(HCC).This prospective cohort study aimed to evaluate the efficacy and safety of lenvatinib plus transarterial chemoembolization(TACE)as an adjuvant therapy in HCC patients with high risk of recurrence.Methods:Patients were enrolled from eight hepatobiliary centers in China.The primary endpoint was disease-free survival(DFS).The secondary endpoints were overall survival(OS)and safety.Additionally,propensity score matching(PSM)and other three propensity score analyses were performed to balance the potential baseline bias to validate the conclusion.The adverse events(AEs)were recorded throughout the study.The study was registered at Clinical Trials.gov(NCT03838796).Results:A total of 297 patients were enrolled,with 147 in the LEN+TACE group and 150 in the TACE group.Before PSM,the LEN+TACE group achieved significantly better DFS than the TACE group(19.0 vs.10.0 months,P=0.011).PSM analysis identified 111 matched pairs.After PSM,the LEN+TACE group also showed better DFS(19.0 vs.9.0 months,P=0.018).Other three propensity score analyses yielded similar DFS benefit tendency.Furthermore,favorable OS was also obtained in the LEN+TACE group before PSM.Lenvatinib related AEs of grade 3 or 4 occurred in 28.6%of the patients in the LEN+TACE group.Conclusions:Adjuvant lenvatinib plus TACE might be a promising adjuvant approach for HCC patients with high risk of recurrence,which could significantly prolong DFS and potentially OS with a manageable safety profile.
文摘BACKGROUND Managing left ventricular outflow tract obstruction(LVOTO)and systolic anterior motion(SAM)of the mitral valve can be challenging,especially in the context of circulatory shock and pulmonary edema post cardiac surgery.CASE SUMMARY We describe a case of an 80-year-old female patient with a history of severe aortic stenosis and hypertrophic obstructive cardiomyopathy that underwent aortic valve replacement and myectomy.The patient presented with acute pulmonary edema and low blood pressure due to LVOTO and SAM post cardiac surgery in the intensive care unit.She was paced with an epicardial dual-chamber pacing system due to complete atrioventricular block and treated initially with norepinephrine,furosemide,and esmolol infusion and continuous positive pressure ventilation.The patient remained hypoxemic and kept deteriorating hemodynamically despite titrating up norepinephrine.The addition of vasopressin infusion and tapering of norepinephrine finally stabilized the patient with significant reduction of LVOTO,confirmed by transthoracic echocardiography assessment,improved oxygenation and increased urine output.CONCLUSION Vasopressin seems to be the preferred vasopressor for managing LVOTO and SAM post-cardiac surgery,because of its absence of inotropic effects.Echocardiography is crucial for early diagnosis and therapeutic management.

文摘Background:Despite advances in surgical treatment,high recurrence after surgery remains a challenge for patients with hepatocellular carcinoma(HCC).This study aimed to investigate the association between compliance to regular follow-up and long-term oncological outcomes among patients undergoing curative resection for HCC.Methods:This multicenter study included patients who underwent curative resection for early-stage HCC between January 2012 and December 2021 at 12 liver surgery centers.Patients were stratified into a regular follow-up group(follow-up every 2–3 months for the first 2 years and every 3–6 months thereafter)and an irregular/no follow-up group.Overall survival(OS),time to recurrence(TTR),and post-recurrence survival(PRS)were compared between the two groups.Results:Among 1544 patients,786(50.9%)underwent regular follow-up during postoperative follow-up.The regular follow-up group had better OS(median:113.4 vs.94.5 months,P=0.010)and PRS(median:37.9 vs.16.3 months,P<0.001)than the irregular/no follow-up group,although TTR was comparable(median:61.4 vs.66.2 months,P=0.161).Furthermore,patients in the regular follow-up group had a lower incidence of tumor beyond the Milan criteria at recurrence(41.6%vs.50.4%,P=0.013)and were more likely to receive curative treatments for recurrence(56.1%vs.49.3%,P=0.061).On multivariate analysis,compliance to regular follow-up was an independent factor associated with better OS[hazard ratio(HR)=0.777,95%confidence interval(CI):0.663–0.910,P=0.002]and PRS(HR=0.523,95%CI:0.428–0.638,P<0.001).Conclusions:Compliance to regular follow-up improved OS and PRS after curative resection for HCC,highlighting the importance of postoperative regular follow-up for early detection of recurrence and timely intervention.
文摘BACKGROUND The survival rate of pancreatic cancer is low,and there is a lack of effective treatment.AIM To explore the epidemiological characteristics of patients with pancreatic cancer in China and compare multiple chemotherapy regimens at different stages.METHODS This was a retrospective study conducted from 2005 to 2014,involving six cancer hospitals and eight general hospitals across seven geographical regions of China(East,South,North,Central,Southwest,Northwest,and Northeast).Stratified sampling was used based on the population distribution of each region.Efficacy assessments were conducted by Cox proportional hazards regression models.When assessing the effectiveness of various chemotherapy regimens,traditional drugs such as gemcitabine used as monotherapy served as the reference.RESULTS A total of 3256 patients were included.The median follow-up time was 407 days,and the median overall survival was 183 days.At diagnosis,56%of patients were already in stage IV.Chemotherapy was administered to 39.73%of patients.In the adjuvant therapy phase,gemcitabine+fluorouracil was superior to gemcitabine monotherapy[hazard ratio(HR)=0.35,95%confidence interval(CI):0.14-0.89].In fluorouracil-based regimens,other combination regimens did not show effectiveness relative to monotherapy.For first-line treatment in patients with advanced disease,tegafur alone(HR=0.20,95%CI:0.06-0.66),gemcitabine plus cisplatin(HR=0.16,95%CI:0.04-0.70),and tegafur,gemcitabine plus platinum-based agents(HR=0.32,95%CI:0.11-0.91)were associated with a lower risk of death compared to gemcitabine alone.In second-line treatment,there were no significant differences in efficacy among various drugs,but FOLFIRINOX(irinotecan+oxaliplatin+leucovorin+5-fluorouracil)had an outstanding point estimate(HR=0.10,95%CI:0.01-1.27).CONCLUSION In China,pancreatic cancer is often diagnosed at advanced stages,emphasizing the need for early diagnosis and treatment.Combined therapies in adjuvant and first-line settings may reduce the risk of death compared with monotherapy,and FOLFIRINOX might offer more significant benefits in second-line treatment.

文摘Introduction With the continuous advancement of surgical technique,combined vascular resection has become increasingly common during complex surgical procedures.In such cases,ensuring the safe and effective reconstruction of blood vessels after resection is of paramount importance.When direct vascular reconstruction is not feasible,the application of vascular grafts becomes necessary to restore vascular continuity and function.Commonly employed vascular grafts in clinical practice include allogeneic graft vessels(AGVs),autologous vessels,and artificial vessels.Among these,AGVs offer distinct advantages particularly in its complex structures and satisfying histocompatibility,making it a valuable option for vascular reconstruction.
文摘Radiofrequency ablation(RFA),particularly endoscopic ultrasound-guided RFA(EUS-RFA),has emerged as a promising minimally invasive approach for the treatment of pancreatic cancer,especially in patients with locally advanced or unresectable disease.This review outlines recent technological developments in EUS-RFA,including innovations in energy delivery systems,probe design,and real-time thermal monitoring,which have improved the precision and safety of the procedure.Clinical studies combining EUS-RFA with chemotherapy have demonstrated encouraging outcomes,with improvements in overall survival,progression-free survival,tumor necrosis,and symptom control compared to chemotherapy alone.Additionally,RFA-induced tumor antigen release and modulation of the tumor microenvironment suggest a potential synergistic role with immunotherapy.Despite its promise,the widespread adoption of EUS-RFA is limited by a lack of large-scale randomized controlled trials and standardized treatment protocols.
文摘Liver transplantation(LT)remains the optimal life-saving intervention for patients with end-stage liver disease.Despite the recent advances in LT several barriers,including organ allocation,donor-recipient matching,and patient education,persist.With the growing progress of artificial intelligence,particularly large language models(LLMs)like ChatGPT,new applications have emerged in the field of LT.Current studies demonstrating usage of ChatGPT in LT include various areas of application,from clinical settings to research and education.ChatGPT usage can benefit both healthcare professionals,by decreasing the time spent on non-clinical work,but also LT recipients by providing accurate information.Future potential applications include the expanding usage of ChatGPT and other LLMs in the field of LT pathology and radiology as well as the automated creation of discharge summaries or other related paperwork.Additionally,the next models of ChatGPT might have the potential to provide more accurate patient education material with increased readability.Although ChatGPT usage presents promising applications,there are certain ethical and practical limitations.Key concerns include patient data privacy,information accuracy,misinformation possibility and lack of legal framework.Healthcare providers and policymakers should collaborate for the establishment of a controlled framework for the safe use of ChatGPT.The aim of this minireview is to summarize current literature on ChatGPT in LT,highlighting both opportunities and limitations,while also providing future possible applications.
文摘Microplastic contamination has emerged as a threat in transplantation,with evidence of its presence in human tissues and potential to compromise grafts.Transplant recipients,vulnerable due to immunosuppression and surgical exposure,face risk from microplastics via airborne particles,surgical materials,and organ preservation systems.These particles trigger inflammation,oxidative stress,and immune dysregulation—pathways critical in rejection.Microplastics support biofilm formation,potentially facilitating antimicrobial resistance in clinical settings.Despite this risk,transplant-specific research is lacking.We urge action through environmental controls,material substitutions,and procedural modifications,alongside research targeting exposure pathways,biological impact,and mitigation strategies.Transplantation has historically led medical innovation and must do so in confronting this environmental challenge.Leadership from global transplant societies is essential to protect recipients and ensure safe procedures.
文摘Green transplant refers to the realization of the importance of understanding and improving the environmental footprint of transplantation through sustainable practices.This involves assessing the entire transplantation process including preoperative evaluation,donation,organ and patient transportation,surgery,postoperative recovery,and follow-up.This is a topic that has not been fully addressed yet,but its importance is being increasingly appreciated in surgery.The aim of this study was to investigate the carbon footprint associated with transplantation and propose sustainable mitigating solutions.A comprehensive review of the existing literature on transplantation was conducted and supplemented with findings from the broader fields of surgical and perioperative care,given the scarcity of available data.The analysis identified the most involved environmental factors and attempted to offer practical solutions based on current sustainability practices.Notably,no study has yet examined the carbon footprint associated with the entire transplantation procedure.Only five studies have attempted to assess the environmental impact of kidney or liver transplants,but they focused,almost explicitly,on specific steps of the process.By employing an extrapolative methodology from the broader surgical field,we determined that the primary contributors to the environmental impact of transplantation are energy,consumables and materials,anesthesia and pharmaceuticals,transportation,and water.This review offers practical solutions utilizing the 5R framework,emphasizing sustainability to ensure transplantation remains clinically and environmentally relevant.
文摘BACKGROUND:The frequency and pattern of hyperbili-rubinemia after open-heart surgery and its severe perioperative complications are not well clarified. The purpose of this study was to investigate the incidence and nature of postoperative jaundice in patients undergoing cardiac operation,to analyze the determinants,and to identify the clinical significance of this complication with regard to the associated morbidity and mortality. METHODS:A prospective observational study was made during the period of 2003-2004 in a Surgical Intensive Care Unit of a Cardiac Surgery Center,Athens. One hundred twenty-eight adult patients for open heart surgery were divided into three groups. Group A included 50 patients who underwent coronary artery bypass crafting(CABG),group B 31 patients who were subjected to aortic valve replacement(AVR)+CABG and group C 47 patients who underwent mitral valve replacement(MVR)+CABG. Aminotransferases,alkaline phosphatase,gamma-glutamyl-transpeptidase and both types of bilirubin were determined at admission,24 hours after the operation and thereafter according to clinical evolution. The presence of jaundice was associated with elevated serum bilirubin above 3 mg/dl. RESULTS:Hyperbilirubinemia developed in 34 patients(26.5%). The incidence of postoperative jaundice was higher in patients who were subjected to MVR+CABG than to CABG and AVR+CABG. Hyperbilirubinemia was correlated with prolonged cardiopulmonary by-passtime(P<0.001),aortic cross-clamping time(P<0.001),the use of intra aortic balloon pumping(P<0.001),the administration of inotrops and the number of blood and plasma transfusions. Postoperative jaundice resulted mainly from an increase in conjugated bilirubin. CONCLUSIONS:Although hyperbilirubinemia seems to be multifactorial,the type of operation,the preoperative hepatic dysfunction due to advanced heart failure(NYHA Ⅱ-Ⅲ) and the decreased hepatic flow during the operation seem to determine the incidence of jaundice.

文摘In an effort to minimize the limitations of laparoscopy,a robotic surgery system was introduced,but its role for gastric cancer is still unclear.The objective of this article is to assess the current status of robotic surgery for gastric cancer and to predict future prospects.Although the current study was limited by its small number of patients and retrospective nature,robot-assisted gastrectomy with lymphadenectomy for the treatment of gastric cancer is a feasible and safe procedure for experienced laparoscopic surgeons.Most studies have reported satisfactory results for postoperative short-term coutcomes,such as:postoperative oral feeding,gas out,hospital stay and complications,compared with laparoscopic surgery;the difference is a longer operation time.However,robotic surgery showed a shallow learning curve compared with the familarity of conventional open surgery;after the accumulation of several cases,robotic surgery could be expected to result in a similar operation time.Robotic-assisted gastrectomy can expand the indications of minimally invasive surgery to include advanced gastric cancer by improving the ability to perform lymphadenectomy.Moreover," total" robotic gastrectomy can be facilitated using a robotsewing technique and gastric submucosal tumors near the gastroesophageal junction or pylorus can be resected safely by this novel technique.In conclusion,robotassisted gastrectomy may offer a good alternative to conventional open or laparoscopic surgery for gastric cancer,provided that long-term oncologic outcomes can be confirmed.
文摘BACKGROUND Patients undergoing cardiac surgery particularly those with comorbidities and frailty,experience frequently higher rates of post-operative morbidity,mortality and prolonged hospital length of stay.Muscle mass wasting seems to play important role in prolonged mechanical ventilation(MV)and consequently in intensive care unit(ICU)and hospital stay.AIM To investigate the clinical value of skeletal muscle mass assessed by ultrasound early after cardiac surgery in terms of duration of MV and ICU length of stay.METHODS In this observational study,we enrolled consecutively all patients,following their admission in the Cardiac Surgery ICU within 24 h of cardiac surgery.Bedside ultrasound scans,for the assessment of quadriceps muscle thickness,were performed at baseline and every 48 h for seven days or until ICU discharge.Muscle strength was also evaluated in parallel,using the Medical Research Council(MRC)scale.RESULTS Of the total 221 patients enrolled,ultrasound scans and muscle strength assessment were finally performed in 165 patients(patients excluded if ICU stay<24 h).The muscle thickness of rectus femoris(RF),was slightly decreased by 2.2%[(95%confidence interval(CI):-0.21 to 0.15),n=9;P=0.729]and the combined muscle thickness of the vastus intermedius(VI)and RF decreased by 3.5%[(95%CI:-0.4 to 0.22),n=9;P=0.530].Patients whose combined VI and RF muscle thickness was below the recorded median values(2.5 cm)on day 1(n=80),stayed longer in the ICU(47±74 h vs 28±45 h,P=0.02)and remained mechanically ventilated more(17±9 h vs 14±9 h,P=0.05).Moreover,patients with MRC score≤48 on day 3(n=7),required prolonged MV support compared to patients with MRC score≥49(n=33),(44±14 h vs 19±9 h,P=0.006)and had a longer duration of extracorporeal circulation was(159±91 min vs 112±71 min,P=0.025).CONCLUSION Skeletal quadriceps muscle thickness assessed by ultrasound shows a trend to a decrease in patients after cardiac surgery post-ICU admission and is associated with prolonged duration of MV and ICU length of stay.

文摘Trauma is a major health and social problem in the US and China, It constitutes the main cause of death in people aged 45 or under in both countries112]. There is clear evidence from clinical studies that a large percentage of these deaths are needless and preventable if better treatment and prevention programs are available12-3].
文摘Physical inactivity remains in high levels after cardiac surgery,reaching up to 50%.Patients present a significant loss of functional capacity,with prominent muscle weakness after cardiac surgery due to anesthesia,surgical incision,duration of cardiopulmonary bypass,and mechanical ventilation that affects their quality of life.These complications,along with pulmonary complications after surgery,lead to extended intensive care unit(ICU)and hospital length of stay and significant mortality rates.Despite the well-known beneficial effects of cardiac rehabilitation,this treatment strategy still remains broadly underutilized in patients after cardiac surgery.Prehabilitation and ICU early mobilization have been both showed to be valid methods to improve exercise tolerance and muscle strength.Early mobilization should be adjusted to each patient’s functional capacity with progressive exercise training,from passive mobilization to more active range of motion and resistance exercises.Cardiopulmonary exercise testing remains the gold standard for exercise capacity assessment and optimal prescription of aerobic exercise intensity.During the last decade,recent advances in healthcare technology have changed cardiac rehabilitation perspectives,leading to the future of cardiac rehabilitation.By incorporating artificial intelligence,simulation,telemedicine and virtual cardiac rehabilitation,cardiac surgery patients may improve adherence and compliance,targeting to reduced hospital readmissions and decreased healthcare costs.
文摘BACKGROUND Lack of mobilization and prolonged stay in the intensive care unit(ICU)are major factors resulting in the development of ICU-acquired muscle weakness(ICUAW).ICUAW is a type of skeletal muscle dysfunction and a common complication of patients after cardiac surgery,and may be a risk factor for prolonged duration of mechanical ventilation,associated with a higher risk of readmission and higher mortality.Early mobilization in the ICU after cardiac surgery has been found to be low with a significant trend to increase over ICU stay and is also associated with a reduced duration of mechanical ventilation and ICU length of stay.Neuromuscular electrical stimulation(NMES)is an alternative modality of exercise in patients with muscle weakness.A major advantage of NMES is that it can be applied even in sedated patients in the ICU,a fact that might enhance early mobilization in these patients.AIM To evaluate safety,feasibility and effectiveness of NMES on functional capacity and muscle strength in patients before and after cardiac surgery.METHODS We performed a search on Pubmed,Physiotherapy Evidence Database(PEDro),Embase and CINAHL databases,selecting papers published between December 2012 and April 2023 and identified published randomized controlled trials(RCTs)that included implementation of NMES in patients before after cardiac surgery.RCTs were assessed for methodological rigor and risk of bias via the PEDro.The primary outcomes were safety and functional capacity and the secondary outcomes were muscle strength and function.RESULTS Ten studies were included in our systematic review,resulting in 703 participants.Almost half of them performed NMES and the other half were included in the control group,treated with usual care.Nine studies investigated patients after cardiac surgery and 1 study before cardiac surgery.Functional capacity was assessed in 8 studies via 6MWT or other indices,and improved only in 1 study before and in 1 after cardiac surgery.Nine studies explored the effects of NMES on muscle strength and function and,most of them,found increase of muscle strength and improvement in muscle function after NMES.NMES was safe in all studies without any significant complication.CONCLUSION NMES is safe,feasible and has beneficial effects on muscle strength and function in patients after cardiac surgery,but has no significant effect on functional capacity.
