Abstract
BACKGROUND Hepatic adenomas (HAs) are benign, solid liver lesions, which carry a risk of hemorrhage and malignant transformation. This review article highlights the advances in the diagnosis and management of HAs. METHODS A comprehensive review was performed using MEDLINE/PubMed and Web of Science databases with a search period ending on September 30, 2023. Using PubMed, the terms "hepatocellular," "hepatic," and "adenoma" were searched. RESULTS HA has been classified into at least 8 subtypes based on molecular pathology, each exhibiting unique histopathologic features, clinical considerations, and risk of malignant transformation. The most common subtype is inflammatory HA, followed by hepatocyte nuclear factor 1α-inactivated HA, β-catenin exon 3-mutated HA (βex3-HA), β-catenin exon 7- or 8-mutated HA, sonic hedgehog HA, and unclassified HA. Magnetic resonance imaging is the best imaging method for diagnosis and can distinguish among HA subtypes based on fat and telangiectasia pathologic characteristics. The risk of malignant transformation varies among molecular subtypes, ranging from <1% to approximately 50%. Up to 42% of HAs present with spontaneous intratumoral hemorrhage and peritoneal hemorrhage. In general, only 15% to 20% of patients require surgery. HA larger than 5 cm are more likely to be complicated by bleeding and malignant transformation, regardless of subtype, and should generally be resected. In particular, βex3-HA carries a high risk of malignant transformation and can be considered a true precancerous lesion. CONCLUSION The management of HAs is based on a multidisciplinary approach. Clinical decision-making should integrate information on gender, tumor size, and HA subtyping. In the future, patients with HA will benefit from novel medical therapies tailored to the individual molecular subtypes.

Abstract
Hepatic hemangioma, focal nodular hyperplasia, and hepatic adenoma are the most common benign solid liver tumors. However, their surgical indications have been the subject of debate. Minimally invasive liver resection reduces the cost of surgery and may lead to overtreatment of benign liver tumors. Recently, there has been a growing understanding of the etiology, pathogenesis, and natural history of these tumors. Great progress has also been made in imaging. The use of MRI and contrast agents has improved the accuracy of non-invasive diagnosis of these tumors, and especially in the identification of specific molecular subtypes of liver adenoma. These factors have resulted in alterations of surgical indications for these tumors. This article examines recent literature and it discusses the surgical indications for hepatic hemangioma, focal nodular hyperplasia, and hepatic adenoma while summarizing modifications in clinical management.

Abstract
Liver is an organ having extremely diversified functions, ranging from metabolic and synthetic to detoxification of harmful chemicals. The multifunctionality of the liver in principle requires the multidisciplinary and pluralistic interventions for its management. Several studies have investigated liver function, dysfunction and clinic. This editorial work discusses new ideas, challenges and perspectives of current research regarding multidisciplinary and pluralistic management of liver diseases. In one hand the discussions have carried out on the involvement of extracellular vesicles, Na+/H+ exchangers, severe acute respiratory syndrome coronavirus 2 and Epstein–Barr virus infections, Drug-induced liver injury, sepsis, pregnancy, and food supplements in hepatic disorders. In the other hand this study has discussed hepatocellular carcinoma algorithms and new biochemical and imaging experiments pertaining to liver diseases. Relevant articles with an impact index value "> 0" from reference citation analysis, which is an open multidisciplinary citation analysis database based on artificial intelligence technology, have served for the study’s argumentation. This work may be a useful tool for the clinical practice and research in managing and investigating liver disorders.

Abstract
BACKGROUND/AIM Recently, an increase in the number of asymptomatic rare benign liver tumors (BLTs) has been reported during health check-ups. It is difficult to determine the nature of partial rare BLTs and not easy to distinguish from malignant liver tumors. This study aimed to analysis clinical features, diagnosis and treatment of rare BLTs to reduce misdiagnosis and provide reference for clinical practice. METHODS From January 2012 to January 2021, we treated 112 rare BLTs by hepatectomy, including 54 focal nodular hyperplasias, 14 hepatocellular adenomas, 28 hepatic angiomyolipomas, 3 hepatic granulomas, 2 inflammatory pseudotumors of the liver, 2 nodular regenerative hyperplasia, 2 hepatic lipomas, 1 solitary fibrous tumor of the liver, 1 hepatic schwannoma and 1 hepatic myelolipoma. RESULTS The majority of patients were middle-aged female and asymptomatic. Single tumors were dominant. The diagnostic accuracies of computed tomography (CT) and magnetic resonance imaging (MRI) were 32.5% and 44.2%, respectively. The majority of tumors were likely to be misdiagnosed as hepatocellular carcinoma (HCC) or difficult to distinguish from HCC. All patients underwent surgical treatment. Postoperative pathological and immunohistochemical examination can confirm the diagnosis. No patients without tumor recurrence or metastasis during follow-up period. CONCLUSION Altogether, the clinical symptoms of rare BLTs lack specificity, and their preoperative diagnosis largely depends on imaging examination, with a low diagnostic accuracy rate and high chances of misdiagnosis as HCC. Diagnosis is confirmed by pathological and immunohistochemical examination. Surgical resection for rare BLT is safe and effective, regular postoperative follow-up is necessary.

Abstract
BACKGROUND Data on surgical outcomes of laparoscopic liver resection (LLR) versus open liver resection (OLR) of benign liver tumour (BLT) are scarce. This study aimed to provide a nationwide overview of postoperative outcomes after LLR and OLR of BLT. METHODS This was a nationwide retrospective study including all patients who underwent liver resection for hepatocellular adenoma, haemangioma and focal nodular hyperplasia in the Netherlands from 2014 to 2019. Propensity score matching (PSM) was applied to compare 30-day overall and major morbidity and 30-day mortality after OLR and LLR. RESULTS In total, 415 patients underwent BLT resection of whom 230 (55.4%) underwent LLR. PSM for OLR and LLR resulted in 250 matched patients. Median (IQR) length of stay was shorter after LLR than OLR (4 versus 6 days, 5.0-8.0, p < 0.001). Postoperative 30-day overall morbidity was lower after LLR than OLR (12.0% vs. 22.4%, p = 0.043). LLR was associated with reduced 30-day overall morbidity in multivariable analysis (aOR:0.46, CI:0.22-0.95, p = 0.043). Both 30-day major morbidity and 30-day mortality were not different. CONCLUSIONS LLR for BLT is associated with shorter hospital stay and reduced overall morbidity and is preferred if technically feasible.

Abstract
BACKGROUND AND AIM Favorable outcomes of laparoscopic hepatectomy (LH) over open hepatectomy (OH) have been demonstrated. LH offers less postoperative morbidity, less blood loss, and shorter hospital stay, while maintaining oncological safety. Only limited evidence about outcomes of LH in elderly is currently available. Therefore, this study aimed to compare short term outcomes of LH to OH for patients >65 years. METHODS A systematic review and meta-analysis were performed according to Cochrane guidelines. Embase, PubMed, Cochrane Library, and Google Scholar were searched to identify eligible studies. Studies were included if they compared LH to OH, and focused on an elderly population, or had a majority of patients >65 years. Perioperative and postoperative outcomes were analyzed. RESULTS Thirteen studies with 1174 patients (LH:532, OH:642) were included for analysis. When compared to OH, elderly undergoing LH had significantly less postoperative complications (risk ratio [RR]0.52; 95% confidence interval (CI):0.43-0.63), less blood loss (mean difference [MD]-198.58; 95% CI:-299.88 to -97.28), and shorter length of stay (MD-4.83; 95%CI:-7.91 to -1.84), while oncological safety was non-inferior (RR1.04; 95%CI:1.00-1.08). CONCLUSIONS Within the elderly population LH seems to be superior to OH, concerning short-term outcomes. However, for broader applicability more trials are needed including more difficult and major resections.

Abstract
As abdominal imaging volumes have increased, the incidence of incidentally identified benign hepatic lesions has substantially increased. Familiarity with imaging appearances of benign hepatic tumors, both common and less commonly encountered, allows the radiologist to give an informed differential diagnosis. In addition to clinical history, awareness of imaging findings of benign hepatic lesions on ultrasound, computed tomography and magnetic resonance imaging is useful in evaluating these lesions and avoiding unnecessary diagnostic interventions or imaging surveillance.

Abstract
Case: Second-generation combined oral contraceptives (COCs) are widely used and are believed to be safe for birth control and in the treatment of gynaecological diseases. No randomised controlled study has shown elevations in alanine transaminase (ALT) levels in relation to the use of a second-generation COC. We report a case of drug-induced liver injury (DILI) in a young, moderately obese woman, due to the use of a second-generation COC containing 30 µg ethinylestradiol and 150 µg levonorgestrel. COC use had been initiated 2 years prior to admission to our department. The diagnosis was based on elevated levels of ALT during COC use and was confirmed by re-challenge and a liver biopsy showing signs of former tissue damage after a 3 week break of COC treatment. Conclusions: To our knowledge, this is the first case of biopsy-proven DILI due to COC use in which a re-challenge was performed.

Abstract
INTRODUCTION Solitary fibrous tumors of the liver (SFTL) are uncommon tumors; to the present day, less than 50 cases has been reported in the English scientific literature, most of which behaved as benign tumors. The present article reports a new case of SFTL and has the main purpose of updating the current knowledge of SFTL because due to its rarity, its clinical presentation, study, treatment, and prognosis are not well known. The clinical presentation, radiologic study, surgical treatment, immunohistochemical study, and prognosis are updated and comprehensively discussed. METHODS Using the common search engines, a search of the English literature was conducted for "Solitary Fibrous Tumor of The Liver," and the relevant articles were retrieved, reviewed, and analyzed. RESULTS All published articles reported anecdotal SFTLs, or SFTLs were included in large series analyzing solitary fibrous tumors on different sites. CONCLUSION The SFTL is an uncommon neoplasm. The clinical presentation is habitually indolent and its behavior is uncertain. In some cases, the SFTL acts as an aggressive sarcoma with poor prognosis. Currently, only surgery offers a therapeutic opportunity for these patients. Due to the lack of current knowledge of long-term behavior of supposedly benign SFTLs and to the lack of specific therapies, methodical long-term follow-up is essential to ensure the survival of patients treated for SFTL.

Abstract
BACKGROUND While minimally invasive surgery (MIS) to treat liver tumors has increased, data on perioperative outcomes of MIS relative to open liver resection (O-LR) are lacking. We sought to compare short-term outcomes among patients undergoing MIS vs. O-LR in a nationally representative database. METHODS The National Surgical Quality Improvement Program database was used to identify patients undergoing hepatectomy between January 1 and December 31, 2014. Propensity score matching algorithm was used to balance differences in baseline characteristics among MIS and O-LR groups. RESULTS A total of 3064 patients were included in the study. After propensity matching, the baseline characteristics for O-LR and MIS groups were comparable (minimum p value = 0.12). Incidence of superficial surgical site infections, intraoperative or postoperative blood transfusions, and pulmonary embolism was lower among patients in MIS group compared to O-LR (p < 0.02). Liver failure and biliary leakage were also less frequent among patients undergoing MIS (p < 0.01). Similarly, MIS was associated with a shorter length of hospital stay (LOS) compared to O-LR (p < 0.001). Of note, 30-day postoperative mortality and readmission were comparable between the two groups. CONCLUSIONS Patients undergoing MIS had a lower postoperative morbidity and shorter LOS compared with patients undergoing O-LR. MIS is safe and may be associated with improved short-term outcomes following hepatic surgery.

Abstract
BACKGROUND Benign liver tumours represent a challenge in clinical management. There is considerable controversy with respect to the indications for surgery as the evidence for surgical treatment is variable. The aim of this retrospective study was to analyse the indication and outcome after resection of benign, solid liver lesions. METHODS Data of 79 patients, who underwent liver resection between 2001 and 2012, were analysed for demographic and outcome parameters. RESULTS Thirty-eight patients with focal nodular hyperplasia (48%), 23 patients with haemangioma (29%) and 18 patients with hepatocellular adenoma (23%) underwent a hepatic resection. A major hepatic resection was performed in 23 patients (29%) and a minor resection in 56 patients (71%). The post-operative mortality rate was zero and the 30-day morbidity rate 13.9%. After a median follow-up of 64 months, 75 patients (95%) were alive, and no patient had developed recurrent disease. Fifty-four patients (68%) were pre-operatively symptomatic, of which, 87% had complete or partial relief of symptoms after a liver resection. The incidence of symptoms increased with the lesions' size. DISCUSSION The management of benign liver lesions necessitates an individualized therapy within a multidisciplinary, evidence-based, treatment algorithm. Resection of benign liver lesions can be performed safely in well-selected patients without mortality and low post-operative morbidity.
