Bronchobiliary fistula (BBF) is one of the most exceptional complications following hepatic surgery. By integrating evidence-based case studies from existing literature, this review offers critical insights into the efficacy of diverse imaging modalities and therapeutic approaches across a broad spectrum of clinical scenarios. Computed tomography, and magnetic resonance cholangiography or even scintigraphy shows an abnormal tractus between biliary ducts and pulmonary bronchi and minimally invasive techniques using endoscopy are considered the techniques of choice. Surgery should only be considered in complicated cases due to significant morbidity and mortality rate. We report the case of a 46-year-old man with metastatic adenocarcinoma of the rectum involving the liver, treated with metastasectomy, which was complicated by a BBF. The patient underwent radiological external drainage followed by endoscopic placement of biliary endoprosthesis with favorable outcome. [ABSTRACT FROM AUTHOR]

Background After major liver resections, anatomical shifts due to liver parenchymal hypertrophy and organ displacement can happen. The aim of this study was to evaluate the impact of these anatomical changes on the main abdominal arteries (coeliac trunk and superior mesenteric artery) and on patient outcomes. Methods All patients who underwent major liver resections (between January 2010 and July 2021) and who underwent preoperative and postoperative arterial-phase contrast-enhanced abdominal CT imaging were studied. Observed arterial position changes were classified into three groups: no position changes; class I position changes (vessel displacement with or without kinking with a vessel angle greater than 105°); and class II position changes (kinking less than or equal to 105°). The Mann–Whitney test and the Kruskal–Wallis test were used to compare continuous variables and the chi-squared test and Fisher's exact test were used to compare categorical variables. Univariable and multivariable logistic regression analyses were used to identify the risk factors for morbidity and mortality. Results A total of 265 patients (149 men and median age of 59 years) were enrolled. Arterial position changes were detected in a total of 145 patients (54.7%) (99 patients (37%) with class I position changes and 46 patients (18%) with class II position changes) and were observed more often after extended resection and right-sided resection (P < 0.001). Major complications were seen in 94 patients (35%) and the rate of mortality was 15% (40 patients died). Post-hepatectomy liver failure (P = 0.030), major complications (P < 0.001), and mortality (P = 0.004) occurred more frequently in patients with class II position changes. In multivariable analysis, arterial position change was an independent risk factor for post-hepatectomy liver failure (OR 2.86 (95% c.i. 1.06 to 7.72); P = 0.038), major complications (OR 2.10 (95% c.i. 1.12 to 3.93); P = 0.020), and mortality (OR 2.39 (95% c.i. 1.03 to 5.56); P = 0.042). Conclusion Arterial position changes post-hepatectomy are observed in the majority of patients and are significantly related to postoperative morbidities and mortality. [ABSTRACT FROM AUTHOR]

They received surgery following successful conversion therapy involving lenvatinib. The patients were matched in a 1:1 ratio to with a control group who underwent direct surgery, based on pre-treatment clinical data.Results: The median recurrence-free survival (RFS) duration for the conversion therapy cohort was notably longer than that of the direct surgery cohort (25 months vs 11 months). Furthermore, the 1- and 2-year RFS rates were significantly higher in the conversion therapy group compared to the direct surgery group (1 year: 70.5% vs 40.1%; 2 years: 49.0% vs 19.1%). The survival curves indicated a statistically significantly longer RFS in the conversion therapy cohort compared to the direct surgery cohort (P = 0.007). While patients achieving good remission based on both RECIST 1.1 and mRECIST criteria showed superior median RFS, no significant disparity was observed in the survival curves. The subgroup analysis revealed significantly improved prognosis among patients in the conversion therapy group who were male, older, had a history of alcohol consumption, were non-smokers, had liver cirrhosis, possessed Child-Pugh A liver function, had a tumor diameter exceeding 5 cm, and had an AFP ≥ 400 ng/mL. Among the cohort of 40 patients, only 8 individuals encountered severe adverse reactions, which were managed through dose reduction. None of the patients experienced multiple severe adverse reactions concurrently.Conclusion: For patients with unresectable hepatocellular carcinoma, conversion therapy offers a significantly better prognosis than direct surgery for uHCC patients.Keywords: hepatocellular carcinoma, conversion therapy, recurrence-free survival, hepatic resection

This study analyzed the long-term effects of carrier-bound fibrin sealant (CBFS) following abdominal surgery by tracking patients for years post-application. From 2006 to 2022, patients who underwent this procedure were contacted via telephone. Those who died due to underlying diseases, natural causes, or refused the check-up were excluded from the study. After 11 years of follow-up, CBFS was observed in different forms on computed tomography scans in four patients. Our findings indicate that CBFS can persist for years after the procedure. While we cannot confirm any secondary effects, it appears that CBFS sponges are not resorbed within 12 weeks and can remain for many years post-implantation. [ABSTRACT FROM AUTHOR]

Purpose of Review: Hepatocellular carcinoma (HCC) is the most common primary liver tumor and 6th most common cancer overall. This article reviews the role of laparoscopy in the multi-disciplinary management of HCC. Recent Findings: Laparoscopic surgery involves multiple approaches for diagnosis and treatment of HCC, including intraoperative ultrasound and biopsy, as well as ablative strategies for tumors in difficult locations. In comparison to catheter-based therapies, hepatic resection offers similar survival with the benefit of direct visualization to identify additional tumors. Laparoscopic liver resections further show similar oncologic outcomes with reduced hospital length of stay and reduced morbidity compared to open approaches and may even be used to treat large tumors. Summary: Laparoscopic surgery may be involved in the diagnosis, treatment, and resection of HCC. Laparoscopic hepatic resections are safe with equivalent oncologic outcomes and may offer advantages over catheter-based therapies in selected patients. Advances in robotic surgery have served to expand the potential for minimally invasive approaches in the surgical treatment of HCC. [ABSTRACT FROM AUTHOR]

Simple Summary: Hepatocellular carcinoma (HCC) is an aggressive form of liver cancer that arises in a background of chronic hepatic injury. Metabolic syndrome-associated fatty liver disease (MAFLD) and its severe form, nonalcoholic steatohepatitis (NASH), are increasingly common mechanisms for new HCC cases. NASH-HCC patients are frequently obese and medically complex, creating challenges when considering interventional therapies. In this review, we discuss NASH-specific challenges and the associated implications for locoregional therapies, surgical resection, and liver transplantation. Hepatocellular carcinoma (HCC) is an aggressive form of liver cancer that arises in a background of chronic hepatic injury. Metabolic syndrome-associated fatty liver disease (MAFLD) and its severe form, nonalcoholic steatohepatitis (NASH), are increasingly common mechanisms for new HCC cases. NASH-HCC patients are frequently obese and medically complex, posing challenges for clinical management. In this review, we discuss NASH-specific challenges and the associated implications, including benefits of minimally invasive operative approaches in obese patients; the value of y90 as a locoregional therapy; and the roles of weight loss and immunotherapy in disease management. The relevant literature was identified through queries of PubMed, Google Scholar, and clinicaltrials.gov. Provider understanding of clinical nuances specific to NASH-HCC can improve treatment strategy and patient outcomes. [ABSTRACT FROM AUTHOR]

We sought to develop Artificial Intelligence (AI) based models to predict non-transplantable recurrence (NTR) of hepatocellular carcinoma (HCC) following hepatic resection (HR). HCC patients who underwent HR between 2000-2020 were identified from a multi-institutional database. NTR was defined as recurrence beyond Milan Criteria. Different machine learning (ML) and deep learning (DL) techniques were used to develop and validate two prediction models for NTR, one using only preoperative factors and a second using both preoperative and postoperative factors. Overall, 1763 HCC patients were included. Among 877 patients with recurrence, 364 (41.5%) patients developed NTR. An ensemble AI model demonstrated the highest area under ROC curves (AUC) of 0.751 (95% CI: 0.719–0.782) and 0.717 (95% CI:0.653–0.782) in the training and testing cohorts, respectively which improved to 0.858 (95% CI: 0.835–0.884) and 0.764 (95% CI: 0.704–0.826), respectively after incorporation of postoperative pathologic factors. Radiologic tumor burden score and pathological microvascular invasion were the most important preoperative and postoperative factors, respectively to predict NTR. Patients predicted to develop NTR had overall 1- and 5-year survival of 75.6% and 28.2%, versus 93.4% and 55.9%, respectively, among patients predicted to not develop NTR (p < 0.0001). The AI preoperative model may help inform decision of HR versus LT for HCC, while the combined AI model can frame individualized postoperative care (https://altaf-pawlik-hcc-ntr-calculator.streamlit.app/).

This article explores the relationship between surgeon volume and the use of laparoscopic liver resection (LLR) in Ontario, Canada. LLR is the preferred method for minor liver resections, but its utilization varies. The study found that surgeons with a higher volume of liver resections were more likely to perform LLR. This information can be used to develop strategies to support LLR programs. Another study examined the association between surgeon resection volume and the use of LLR in patients with gastrointestinal cancer. The results showed that patients treated by high-volume liver surgeons were more likely to have their hepatectomy performed laparoscopically. The study suggests that directing complex liver surgery to high-volume surgeons and implementing policy changes could increase the use of LLR. [Extracted from the article]

Background Validating the expanded criteria for living donor liver transplantation for hepatocellular carcinoma using national data is highly significant. The aim of this study was to evaluate the validity of the new Japanese criteria for living donor liver transplantation for hepatocellular carcinoma patients and identify factors associated with a poor prognosis using the Japanese national data set. Methods The study population comprised patients who underwent living donor liver transplantation for hepatocellular carcinoma at 37 centres in Japan between 2010 and 2018. In a nationwide survey, the overall survival and recurrence-free survival rates were evaluated based on the new Japanese criteria for applying the 5-5-500 rule when extending the indication beyond the Milan criteria. Prognostic factors within the Japanese criteria were determined using the Cox proportional hazards model. Results Patients within (485 patients) and beyond (31 patients) the Japanese criteria exhibited 5-year overall survival rates of 81% and 58% and 5-year recurrence-free survival rates of 77% and 48% respectively. Patients who met the Milan criteria, but not the 5-5-500 rule, had poorer outcomes. Multivariate analysis for 474 patients identified a neutrophil-to-lymphocyte ratio greater than or equal to 5 and a history of hepatectomy as independent risk factors. Conclusion This nationwide survey confirms the validity of the Japanese criteria. The poor prognostic factors within the Japanese criteria include a neutrophil-to-lymphocyte ratio greater than or equal to 5 and previous hepatectomy. [ABSTRACT FROM AUTHOR]

Background: Liver resection is a critical surgical procedure for treating various hepatic pathologies. Minimally invasive approaches have gradually gained importance, and, in recent years, the introduction of robotic surgery has transformed the surgical landscape, providing potential advantages such as enhanced precision and stable ergonomic vision. Among robotic techniques, the single-site approach has garnered increasing attention due to its potential to minimize surgical trauma and improve cosmetic outcomes. However, the full extent of its utility and efficacy in liver resection has yet to be thoroughly explored. Methods: We conducted a comprehensive systematic review to evaluate the current role of the single-site robotic approach in liver resection. A detailed search of PubMed was performed to identify relevant studies published up to January 2024. Eligible studies were critically appraised, and data concerning surgical outcomes, perioperative parameters, and post-operative complications were extracted and analyzed. Results: Our review synthesizes evidence from six studies, encompassing a total of seven cases undergoing robotic single-site hepatic resection (SSHR) using various versions of the da Vinci© system. Specifically, the procedures included five left lateral segmentectomy, one right hepatectomy, and one caudate lobe resection. We provide a summary of the surgical techniques, indications, selection criteria, and outcomes associated with this approach. Conclusion: The single-site robotic approach represents an option among the minimally invasive approaches in liver surgery. However, although the feasibility has been demonstrated, further studies are needed to elucidate its optimal utilization, long-term outcomes, and comparative effectiveness against the other techniques. This systematic review provides valuable insights into the current state of single-site robotic liver resection and underscores the need for continued research in this rapidly evolving field.

Aim: The present study aimed to compare the long-term survival outcomes of hepatic resection (HR) and radiofrequency ablation (RFA) in patients with single small (≤2 cm) hepatocellular carcinoma (HCC).Materials & methods: This retrospective study enrolled patients with a single small HCC measuring 2 cm or smaller underwent HR or RFA as their initial treatment.Results: Overall survival (OS) was significantly higher in the HR group than in the RFA group, while no significant difference was observed in recurrence free survival (RFS) between the two groups. However, after propensity score matching, both OS and RFS in the HR group were significantly higher than in the RFA group. Multivariate analysis showed that patients with hepatitis B virus infection, elevated prothrombin-induced by vitamin K absence or antagonist-II, and albumin–bilirubin (ALBI) grade 2/3 before treatment had poorer OS. Patients with ALBI grade 1 in the HR group demonstrated the highest OS.Conclusion: HR showed significantly better long-term OS and RFS compared with RFA in patients with as a single HCC (≤2 cm). Moreover, the ALBI grade may help identify patients who would benefit from HR or RFA.

Hepatocellular carcinoma (HCC) is the second most common cause of cancer mortality worldwide. Liver resection is considered the pillar of curative treatment, although it is usually reserved for early-stage localized disease since the presence of metastases carries a poor prognosis. Despite advances in imaging, surgical techniques, and systemic therapy, the recurrence rate after oncologic resection remains high, even with localized disease. In the setting of extrahepatic HCC recurrence, there is no consensus regarding the best treatment strategy. Nevertheless, while the development of metastasis can be considered an expression of systemic disease, surgical resection may prolong survival. We report the case of a patient with a history of an oncologic hepatic resection for HCC, successfully treated with resection of an isolated peritoneal cavity metastasis. This case demonstrates that an aggressive approach involving the resection of extrahepatic HCC metastasis should be considered in select patients with the intention of achieving prolonged survival.

Abstract Background Postoperative delirium (POD) is a common complication after major surgery and can cause a variety of adverse effects. However, no large-scale national database was used to assess the occurrence and factors associated with postoperative delirium (POD) following hepatic resection. Methods Patients who underwent hepatic resection from 2015 to 2019 were screened using the International Classification of Diseases (ICD) 10th edition clinical modification code from the National Inpatient Sample (NIS) Database. Peri-operative factors associated with delirium were screened and underwent statistical analysis to identify independent predictors for delirium following hepatic resection. Results A total of 80,070 patients underwent hepatic resection over a five-year period from 2015 to 2019. The overall occurrence of POD after hepatic resection was 1.46% (1039 cases), with a slight upward trend every year. The incidence of elective admission was 6.66% lower (88.60% vs. 81.94%) than that of patients without POD after hepatic resection and 2.34% (45.53% vs. 43.19%) higher than that of patients without POD in teaching hospitals (P

Abstract Development of subclassification of intermediate-stage hepatocellular carcinoma (HCC) by treatment suitability is in demand. We aimed to identify predictors that define treatment refractoriness against locoregional(transarterial chemoembolization(TACE) or thermal ablation) and surgical therapy. This multicenter retrospective study enrolled 1167 HCC patients between 2015 and 2021. Of those, 209 patients were initially diagnosed with intermediate-stage HCC. Treatment refractoriness was defined as clinical settings that meets the following untreatable progressive conditions by TACE (1) 25% increase of intrahepatic tumor, (2) transient deterioration to Child–Pugh class C, (3) macrovascular invasion or extrahepatic spread, within one year. We then analyzed factors contributing to treatment refractoriness. The Child–Pugh score/class, number of tumors, infiltrative radiological type, and recurrence were significant factors. Focusing on recurrence as a predictor, median time to untreatable progression (TTUP) was 17.2 months in the recurrence subgroup whereas 35.5 months in the initial occurrence subgroup (HR, 2.06; 95% CI, 1.44–2.96; P = 0.001). Median TTUP decreased in cases with more later times of recurrence (3–5 recurrences, 17.3 months; ≥ 6 recurrences, 7.7 months). Recurrence, even more at later times, leads to increased treatment refractoriness. Early introduction of multidisciplinary treatment should be considered against HCC patients after multiple recurrent episodes.

Abstract Background Few studies have assessed enhanced recovery after surgery (ERAS) in liver surgery for cirrhotic patients. The present meta-analysis assessed the impact of ERAS pathways on outcomes after liver surgery in cirrhotic patients compared to standard care. Methods A literature search was performed on PubMed/MEDLINE, Embase, and the Cochrane Library. Studies comparing ERAS protocols versus standard care in cirrhotic patients undergoing liver surgery were included. The primary outcome was post-operative complications, while secondary outcomes were mortality rates, length of stay (LoS), readmissions, reoperations, and liver failure rates. Results After evaluating 41 full-text manuscripts, 5 articles totaling 646 patients were included (327 patients in the ERAS group and 319 in the non-ERAS group). Compared to non-ERAS care, ERAS patients had less risk of developing overall complications (OR 0.43, 95% CI 0.31–0.61, p

Background: We aimed to study the prognostic impact of sarcopenia on overall survival (OS), disease-free survival (DFS), and postoperative outcomes among patients with Hepatocellular carcinoma (HCC) who underwent curative hepatic resection. Methods: Data were collected retrospectively from patients with HCC underwent curative hepatic resection and preoperative abdominal computed tomography (CT) at our institution between January 2010 and December 2020. Sarcopenia was evaluated by the skeletal muscle mass at the inferior direction of the third-lumbar-vertebra (L3) cross-sectional area based on preoperative CT imaging using software analysis. Cutoff values for skeletal muscle index (SMI) were 43.75 and 41.10 cm2/m2 for males and females. The patients were classified into sarcopenia and nonsarcopenia groups. The association between preoperative sarcopenia and clinicopathological factors, impact of sarcopenia on survival, and postoperative outcomes were analyzed. Results: Sarcopenia was present in 39 of 83 (47.0%) patients who underwent curative hepatic resection for HCC and was significantly correlated with lower SMI, lower serum albumin levels, higher intraoperative blood loss, higher postoperative complications, and longer hospital stay. The 5-year OS was significantly lower in sarcopenic patients than in nonsarcopenic patients (58.2% vs 83.6%; P =.006), but the 5-year DFS was not significantly different between the 2 groups. Multivariate analysis revealed that sarcopenia was a significant risk factor for poor OS (HR 4.728; 95% CI, 1.458-15.329; P =.010). Conclusion: Sarcopenia was identified as a prognostic factor for poor OS after hepatic resection, and major postoperative complications were more frequent in sarcopenia. Early sarcopenia detection and management may improve OS and clinical outcomes in postoperative HCC. [ABSTRACT FROM AUTHOR]

Background: Postoperative delirium (POD) is a common complication after major surgery and can cause a variety of adverse effects. However, no large-scale national database was used to assess the occurrence and factors associated with postoperative delirium (POD) following hepatic resection.

The incidence of elective admission was 6.66% lower (88.60% vs. 81.94%) than that of patients without POD after hepatic resection and 2.34% (45.53% vs. 43.19%) higher than that of patients without POD in teaching hospitals (P < 0.001). In addition, POD patients were 6 years older (67 vs. 61 years) and comprised 9.27% (56.69% vs. 47.42%) more male patients (P < 0.001) compared to the unaffected population. In addition, the occurrence of POD was associated with longer hospitalization duration (13 vs. 5 days; P < 0.001), higher total cost ($1,481,89 vs. $683,90; P < 0.001), and higher in-hospital mortality (12.61% vs. 4.11%; P < 0.001). Multivariate logistic regression identified hepatic resection-independent risk factors for POD, including non-elective hospital admission, teaching hospital, older age, male sex, depression, fluid and electrolyte disorders, coagulopathy, other neurological disorders, psychoses, and weight loss. In addition, the POD after hepatic resection has been associated with sepsis, dementia, urinary retention, gastrointestinal complications, acute renal failure, pneumonia, continuous invasive mechanical ventilation, blood transfusion, respiratory failure, and wound dehiscence / non-healing. Conclusion: Although the occurrence of POD after hepatic resection is relatively low, it is beneficial to investigate factors predisposing to POD to allow optimal care management and improve the outcomes of this patient population.

There are few reports on duct-to-duct biliary reconstruction for complex liver resection with limited bile duct resection. We performed duct-to-duct biliary reconstruction in two patients undergoing limited bile duct resection where Roux-en-Y hepaticojejunostomy (HJ) was difficult. An external biliary drainage tube was placed routinely at the anastomotic site to prevent stenosis. In case 1, the tumor-infiltrated part of the left hepatic duct (LHD) was resected and the LHD was repaired using duct-to-duct reconstruction with interrupted sutures. In case 2, after the tumor-infiltrated part of the LHD and posterior hepatic duct (PHD) were resected, T-tube reconstruction was performed on the PHD, and the LHD was anastomosed using interrupted sutures for the posterior wall and a round ligament patch for the anterior wall. Our literature review suggests that an external biliary drainage tube with stenting over the anastomosis may reduce the risk of biliary complications. [ABSTRACT FROM AUTHOR]

The present meta-analysis assessed the impact of ERAS pathways on outcomes after liver surgery in cirrhotic patients compared to standard care. Methods: A literature search was performed on PubMed/MEDLINE, Embase, and the Cochrane Library. Studies comparing ERAS protocols versus standard care in cirrhotic patients undergoing liver surgery were included. The primary outcome was post-operative complications, while secondary outcomes were mortality rates, length of stay (LoS), readmissions, reoperations, and liver failure rates. Results: After evaluating 41 full-text manuscripts, 5 articles totaling 646 patients were included (327 patients in the ERAS group and 319 in the non-ERAS group). Compared to non-ERAS care, ERAS patients had less risk of developing overall complications (OR 0.43, 95% CI 0.31–0.61, p < 0.001). Hospitalization was on average 2 days shorter for the ERAS group (mean difference − 2.04, 95% CI − 3.19 to − 0.89, p < 0.001). Finally, no difference was found between both groups concerning 90-day post-operative mortality and rates of reoperations, readmissions, and liver failure. Conclusion: In cirrhotic patients, ERAS protocol for liver surgery is safe and decreases post-operative complications and LoS. More randomized controlled trials are needed to confirm the results of the present analysis. [ABSTRACT FROM AUTHOR]

Background: The impact of hepatic resection type on long-term oncological prognosis of patients with early-stage hepatocellular carcinoma (HCC) has not been systematically investigated. We sought to determine risk factors, recurrence patterns, and survival outcomes after anatomical resection (AR) versus non-anatomical resection (NAR) for early-stage HCC. Methods: From a prospectively collected multicenter database, consecutive patients undergoing curative hepatectomy for early-stage HCC were identified. Recurrence patterns, overall survival (OS), recurrence-free survival (RFS), and risk factors were investigated in patients undergoing AR versus NAR using propensity score matching (PSM), subgroup analysis, and COX regression analysis. Results: A total of 3585 patients with early-stage HCC were enrolled, including 1287 and 2298 in the AR and NAR groups, respectively. After PSM, the OS and RFS of patients in the AR group were 58.8% and 42.7%, which were higher than those in the NAR group (52.2% and 30.6%, both p < 0.01). The benefits of AR were consistent across most subgroup analyses of OS and RFS. Multivariable COX regression analysis showed that AR was independently associated with better OS and RFS. Notably, although recurrence patterns were comparable, the risk factors for recurrence were not identical for AR versus NAR. Microvascular invasion and narrow resection margin were only associated with a higher recurrence rate after NAR. Conclusions: This study demonstrated that AR decreases the risk of tumor recurrence and improves OS and RFS in patients with early-stage HCC. AR should be adopted as long as such a surgical maneuver is feasible for initial treatment of early-stage HCC. [ABSTRACT FROM AUTHOR]

A grading system of MVI is needed to assist in the management of HCC patient.Methods: Multicenter data of HCC patients who underwent liver resection with curative intent was analyzed. This grading system was established by detected number and distance from tumor boundary of MVI. Survival outcomes were compared among patients in each group. This system was verified by time-receiver operating characteristic curve, time-area under the curve, calibration curve, and decision curve analyses. Cox regression analysis was performed to study the associated factors of prognosis. Logistic analysis was used to study the predictive factors of MVI.Results: All patients were classified into 4 groups: M0: no MVI; M1: 1~5 proximal MVIs (≤ 1 cm from tumor boundary); M2a: > 5 proximal MVIs (≤ 1 cm from tumor boundary); M2b: ≥ 1 distal MVIs (> 1 cm from tumor boundary). The recurrence-free survival (RFS), overall survival (OS), and early RFS rates among all the individual groups were significantly different. Based on the number of proximal MVI (0~5 vs > 5), patients in the M2b group were further divided into two subgroups which also showed different prognosis. Multiple methods showed this grading system to be significantly better than the MVI two-tiered system in prognostic evaluation. Four multivariate models for RFS, OS, early RFS, late RFS, and a predictive model of MVI were then established and were shown to satisfactorily evaluate prognosis and have a great discriminatory power, respectively.Conclusion: This MVI grading system could precisely evaluate prognosis of HCC patients after liver resection with curative intent and it could be employed in routine pathological reports. The severity of MVI from both adjacent and distant from tumor boundary should be stated. A hypothesis about two occurrence modes of distal MVI was proposed.

Abstract Background Systemic inflammatory response represented by C‐reactive protein and albumin ratio (CAR) and modified albumin‐bilirubin (mALBI) grade both have been associated with long‐term outcome in patients with hepatocellular carcinoma (HCC). In this study, we investigated the prognostic utility of combined score of CAR and mALBI score to predict the prognosis of HCC patients after hepatic resection. Methods This study included 214 patients who had undergone primary hepatic resection for HCC between 2008 and 2018. Systemic inflammatory response and mALBI were evaluated preoperatively and patients were classified into three groups based on the combination of CAR and mALBI score: low CAR and low mALBI grade (score 0), either high CAR or high mALBI grade (score 1), and both high CAR and high mALBI grade ≥2b (score 2). Multivariate Cox proportional hazard models were conducted to assess disease‐free and overall survival. Results In multivariate analysis, sex (p

Multivariate COX regression analysis was performed to identify the independent prognostic factors related to recurrence-free survival (RFS). The performance of the developed nomogram was evaluated using various statistical measures, including the concordance index (C-index), receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA).Results: Multivariate analysis revealed that tumor diameter, number of tumors, number of involved liver segments, alpha-fetoprotein (AFP), carbohydrate antigen 19– 9 (CA19-9), lactate dehydrogenase (LDH), and systemic immune inflammation index (SII) were independent prognostic factors influencing patients’ RFS, and these factors were incorporated into the nomogram. The C-index of the nomogram in the training cohort was 0.721, and the AUC at 2 and 3 years was 0.772 and 0.790, respectively. These values were appreciably higher than commonly used clinic staging systems and other predictive models. The calibration curve and DCA demonstrated good calibration and net benefit. Survival analysis comparing stage B patients who received radical treatment with stage A patients with multiple lesions did not reveal a significant difference in Kaplan-Meier survival curves (P=0.91).Conclusion: The nomogram provided a precise prediction of the recurrence for stage B hepatocellular carcinoma patients undergoing radical treatment. Furthermore, certain stage B patients may benefit from radical treatment.Keywords: nomogram, Barcelona clinic Liver cancer system, recurrence-free survival, hepatic resection, radiofrequency ablation

Background The prognostic significance of the aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio in hepatocellular carcinoma remains uncertain. The aim of the current study was to evaluate the association between the AST/ALT ratio and prognosis in patients with hepatocellular carcinoma after hepatectomy, and to explore the role of underlying liver diseases as mediators. Methods This retrospective study included patients with hepatocellular carcinoma who underwent hepatectomy between January 2014 and January 2018 at two Chinese hospitals. The maximally selected rank statistic and g-computation approach were used to quantify and visualize the association between the AST/ALT ratio and overall survival or recurrence-free survival. The role of mediators (chronic hepatitis B, hepatic steatosis and liver cirrhosis) was analysed. Results Among the 1519 patients (mean(s.d.) age at baseline, 50.5(11.3) years), 1309 (86.2%) were male. During a median follow-up of 46.0 months, 514 (33.8%) patients died and 358 (23.6%) patients experienced recurrence. The optimal cut-off value for the AST/ALT ratio was 1.4, and the AST/ALT ratio greater than or equal to 1.4 was independently associated with a 39.0% increased risk of death and a 30.0% increased risk of recurrence (overall survival: hazard ratio (HR), 1.39; 95% c.i. 1.15 to 1.68; recurrence-free survival: HR, 1.30; 95% c.i. 1.12 to 1.52) after adjusting for confounders. Chronic hepatitis B significantly mediated the association of the ratio of AST/ALT with both overall survival and recurrence-free survival (20.3% for overall survival; 20.1% for recurrence-free survival). Conclusion The AST/ALT ratio greater than or equal to 1.4 was associated with shorter overall survival and recurrence-free survival in patients with hepatocellular carcinoma after hepatectomy, and chronic hepatitis B may play a role in their association.

Background The 2022 Barcelona Clinic Liver Cancer (BCLC) algorithm does not recommend liver resection (LR) in BCLC A patients with oligo-nodular (two or three nodules ≤3   cm) hepatocellular carcinoma (HCC). This sharply contrasts with the therapeutic hierarchy concept, implying a precise treatment order exists within each BCLC stage. This study aimed to compare the outcomes of LR versus radiofrequency ablation (RFA) or trans-arterial chemoembolization (TACE) in BCLC A patients. Methods A meta-analysis adhering to PRISMA guidelines and the Cochrane Handbook was performed. All RCT, cohort and case–control studies that compared LR versus RFA or TACE in oligo-nodular BCLC A HCC published between January 2000 and October 2023 were comprehensively searched on PubMed, Embase, the Cochrane Library and China Biology Medicine databases. Primary outcomes were overall survival (OS) and disease-free survival (DFS) at 3 and 5 years. Risk ratio (RR) was computed as a measure of treatment effect (OS and DFS benefit) to calculate common and random effects estimates for meta-analyses with binary outcome data. Results 2601 patients from 14 included studies were analysed (LR = 1227, RFA = 686, TACE = 688). There was a significant 3- and 5-year OS benefit of LR over TACE (RR = 0.55, 95% c.i. 0.44 to 0.69, P < 0.001 and RR 0.57, 95% c.i. 0.36 to 0.90, P = 0.030, respectively), while there was no significant 3- and 5-year OS benefit of LR over RFA (RR = 0.78, 95% c.i. 0.37 to 1.62, P = 0.452 and RR 0.74, 95% c.i. 0.50 to 1.09, P = 0.103, respectively). However, a significant 3- and 5-year DFS benefit of LR over RFA was found (RR = 0.70, 95% c.i. 0.54 to 0.93, P = 0.020 and RR 0.82, 95% c.i. 0.72 to 0.95, P = 0.015, respectively). A single study comparing LR and TACE regarding DFS showed a significant superiority of LR. The Newcastle–Ottawa Scale quality of studies was high in eight (57%) and moderate in six (43%). Conclusions In BCLC A oligo-nodular HCC patients, LR should be preferred to RFA or TACE (therapeutic hierarchy concept). Additional comparative cohort studies are urgently needed to increase the certainty of this evidence. [ABSTRACT FROM AUTHOR]

Background: Systemic inflammatory response represented by C‐reactive protein and albumin ratio (CAR) and modified albumin‐bilirubin (mALBI) grade both have been associated with long‐term outcome in patients with hepatocellular carcinoma (HCC). In this study, we investigated the prognostic utility of combined score of CAR and mALBI score to predict the prognosis of HCC patients after hepatic resection. Methods: This study included 214 patients who had undergone primary hepatic resection for HCC between 2008 and 2018. Systemic inflammatory response and mALBI were evaluated preoperatively and patients were classified into three groups based on the combination of CAR and mALBI score: low CAR and low mALBI grade (score 0), either high CAR or high mALBI grade (score 1), and both high CAR and high mALBI grade ≥2b (score 2). Multivariate Cox proportional hazard models were conducted to assess disease‐free and overall survival. Results: In multivariate analysis, sex (p < 0.01), HBsAg positivity (p < 0.01), serum AFP level ≥20 ng/mL (p < 0.01), microvascular invasion (p = 0.02), multiple tumors (p < 0.01), type of resection (p < 0.01), and CAR‐mALBI score ≥2 (HR 2.19, 95% CI 1.39–3.44, p < 0.01) were independent prognostic factors of disease‐free survival, while sex (p = 0.01), HBsAg positivity (p < 0.01), poor tumor differentiation (p = 0.03), multiple tumors (p < 0.01), CAR‐mALBI score ≥2 (HR 2.70, 95% CI 1.51–4.83, p < 0.01) were independent prognostic factors of overall survival. Conclusions: CAR‐mALBI score is associated with disease‐free and overall survival in patients with HCC after hepatic resection, suggesting the importance of evaluating both hepatic functional reserve and host‐inflammatory state in the risk assessment of HCC patients.

Bile leakage is a common complication following liver surgeries, particularly in the cases of liver hydatid cyst operations. Currently, there is no adequate method which could be utilized to prevent this complication effectively. Our study aimed to assess the efficacy of the biliary lipid test (BLT) in reducing biliary complications after hydatid cyst surgery. We retrospectively included patients who underwent open liver hydatid cyst surgery between January 2011 and January 2024. The study encompassed 122 patients, with 41 males and 81 females, ranging in age from 18 to 79 years. In the BLT group, a lipid solution was injected transcystically after cholecystectomy. The BLT was performed on 65 patients, while 57 patients did not undergo the test. Following the transcystic injection of the lipid solution, orifices at the site of lipid droplets that became visible were ligated with 5.0 prolene sutures. A total of 200 leak sites were sutured. Notably, none of the patients in the BLT group experienced postoperative bile leakage. Consequently, a shorter hospital stay was observed in this group. Transcystic injection of the lipid solution with distal clamping effectively demonstrated leak sites, and suturing these sites prevented postoperative bile leakage. Our study demonstrates the effectiveness of the LIpid test in LIver Hydatid Cyst Surgery (Lili-Hics) in reducing biliary complications following hydatid cyst surgery.

Chylous ascites is an uncommon pathology with low incidence following hepato-pancreato-biliary surgery, there are no cases reported in the international literature following the associating liver partition and portal vein ligation for stage hepatectomy (ALPPS) procedure. It is caused by abnormal intraperitoneal accumulation of lymph fluid in the abdominal cavity secondary to obstruction or injury to the chyle cistern or its tributaries. We describe the case of a 49-year-old woman diagnosed with colon cancer and liver metastasis. ALPPS was performed, on a first and second stage, presenting a high drainage output as well as change in the characteristics of the drainage fluid. The diagnosis of chylous ascites was confirmed by finding triglyceride levels in the drainage fluid at 300 mg/dL. Medical treatment was started based on a hyper-protein diet and fat restriction, supplemented with medium-chain triglycerides and somatostatin analog, with fistula resolution. It can be managed with medical treatment. [ABSTRACT FROM AUTHOR]

Mesenchymal hamartoma of the liver (MHL) is rare. Less than 50 adult cases have been described. Due to their potential degeneration or recurrence, a complete surgical resection must be performed. We describe a case of a 26-year-old with a palpable solid lesion, which displaced abdominal organs. Percutaneous needle biopsies suggested the diagnosis of MHL. A right hemi-hepatectomy without segment 1 was performed; the post-operative course was uneventful. The mesenchymal component of the tumour was reactive to desmin and smooth muscle actin. Low proliferation index was confirmed (MIB1). Genetic counselling: the sequencing analysis of DICER1 and CDKN1C gene was negative, DNA methylation analysis on the chromosome 11p15 region was normal. After 42 months, there was no recurrence. In conclusion, clinicians should consider MHL in the differential diagnosis. The dimension and the need of radicality impose major liver resections or liver transplantations, which should be performed in referral centres. [ABSTRACT FROM AUTHOR]

Background: Liver resection is a critical surgical procedure for treating various hepatic pathologies. Minimally invasive approaches have gradually gained importance, and, in recent years, the introduction of robotic surgery has transformed the surgical landscape, providing potential advantages such as enhanced precision and stable ergonomic vision. Among robotic techniques, the single-site approach has garnered increasing attention due to its potential to minimize surgical trauma and improve cosmetic outcomes. However, the full extent of its utility and efficacy in liver resection has yet to be thoroughly explored. Methods: We conducted a comprehensive systematic review to evaluate the current role of the single-site robotic approach in liver resection. A detailed search of PubMed was performed to identify relevant studies published up to January 2024. Eligible studies were critically appraised, and data concerning surgical outcomes, perioperative parameters, and post-operative complications were extracted and analyzed. Results: Our review synthesizes evidence from six studies, encompassing a total of seven cases undergoing robotic single-site hepatic resection (SSHR) using various versions of the da Vinci© system. Specifically, the procedures included five left lateral segmentectomy, one right hepatectomy, and one caudate lobe resection. We provide a summary of the surgical techniques, indications, selection criteria, and outcomes associated with this approach. Conclusion: The single-site robotic approach represents an option among the minimally invasive approaches in liver surgery. However, although the feasibility has been demonstrated, further studies are needed to elucidate its optimal utilization, long-term outcomes, and comparative effectiveness against the other techniques. This systematic review provides valuable insights into the current state of single-site robotic liver resection and underscores the need for continued research in this rapidly evolving field.

Metastatic melanoma is a significant public health issue in Australia and New Zealand. Although melanoma commonly metastasises to the liver, isolated hepatic metastases are rare, with isolated metastasis to portohepatic lymph nodes being scarce. As such, the optimal management strategy for this subset of patients remains unclear. Here, we present a case of a patient with isolated portohepatic metastases management with a combination neoadjuvant immunotherapy and surgical resection. [ABSTRACT FROM AUTHOR]

Objective: Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related mortality globally. In our region, there is a scarcity of studies addressing its epidemiology and treatment. The aim was to characterize a cohort of HCC patients in a high-complexity public center in Argentina over a span of 10 years., Method: This study employed a retrospective observational and analytical cohort design. All patients aged 18 and above, diagnosed with HCC between January 2013 and December 2022 at Hospital El Cruce, were included., Results: The cohort comprised 380 patients, 75% being male, average age of 57 ± 10.14 years. Cirrhotic liver was evident in 94% of cases. Surgery was employed in 182 (138 hepatic transplants, 44 surgical resections), locoregional therapies in 121 (104 sole transarterial chemoembolization, and 17 in combination), and one radiofrequency ablation. Systemic treatment was administered to 34 patients, 17 of whom received it as monotherapy. Mortality within the series according to the Barcelona Clinic Liver Cancer (BCLC) staging: 0, 1/2 (50%); A, 92/220 (41.8%); B, 60/98 (61.2%); C, 21/23 (91.3%); D, 37/37 (100%)., Conclusions: HCC emerges as a complex tumor with an unfavorable prognosis, underscoring the pivotal role of prevention and early detection in improving outcomes.

Background: The impact of frailty on postoperative outcomes in patients undergoing hepatectomy is still unclear., Aim: To study the influence of frailty on postoperative outcomes, such as mortality, rate of complications, and length of hospitalization, following hepatectomy., Methods: PubMed, EMBASE, and Scopus databases were searched for observational studies with adult (≥ 18 years) patients after planned/elective hepatectomy. A random-effects model was used for all analyses, and the results are expressed as weighted mean difference (WMD), relative risk (RR), or hazards ratio (HR) with 95% confidence interval (CI)., Results: Analysis of the 13 included studies showed a significant association of frailty with elevated risk of in-hospital mortality (RR = 2.76, 95%CI: 2.10-3.64), mortality at 30 d (RR = 4.60, 95%CI: 1.85-11.40), and mortality at 90 d (RR = 2.52, 95%CI: 1.70-3.75) in the postoperative period. Frail patients had a poorer long-term survival (HR = 2.89, 95%CI: 1.84-4.53) and higher incidence of "any" complications (RR = 1.69, 95%CI: 1.40-2.03) and major (grade III or higher on the Clavien-Dindo scale) complications (RR = 2.69, 95%CI: 1.85-3.92). Frailty was correlated with markedly lengthier hospital stay (WMD = 3.65, 95%CI: 1.45-5.85)., Conclusion: Frailty correlates with elevated risks of mortality, complications, and prolonged hospitalization, which need to be considered in surgical management. Further research is essential to formulate strategies for improved outcomes in this vulnerable cohort., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.
