RESUMO

OBJECTIVE: Pharmacological prevention of postoperative pancreatic fistula (POPF) after pancreatectomy is open to debate. The present study compares clinically significant POPF rates in patients randomized between somatostatin versus octreotide as prophylactic treatment. PATIENTS AND METHODS: Multicentric randomized controlled open study in patient's candidate for pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) comparing somatostatin continuous intravenous infusion for 7 days versus octreotid 100 µg, every 8 hours subcutaneous injection for 7 days, stratified by procedure (PD vs. DP) and size of the main pancreatic duct (>4 mm) on grade B/C POPF rates at 90 days based on an intention-to-treat analysis. RESULTS: Of 763 eligible patients, 651 were randomized: 327 in the octreotide arm and 324 in the somatostatin arm, with comparable the stratification criteria - type of surgery and main pancreatic duct dilatation. Most patients had PD (n=480; 73.8%), on soft/normal pancreas (n=367; 63.2%) with a non-dilated main pancreatic duct (n=472; 72.5%), most often for pancreatic adenocarcinoma (n=311; 47.8%). Almost all patients had abdominal drainage (n=621; 96.1%) and 121 (19.5%) left the hospital with the drain in place (median length of stay=16 d). A total of 153 patients (23.5%) developed a grade B/C POPF with no difference between both groups: 24.1%: somatostatin arm and 22.9%: octreotide arm (Chi-2 test, P=0.73, ITT analysis). Absence of statistically significant difference persisted after adjustment for stratification variables and in per-protocol analysis. CONCLUSIONS: Continuous intravenous somatostatin is not statistically different from subcutaneous octreotide in the prevention of grade B/C POPF after pancreatectomy.

RESUMO

The aim of this study was to assess the publication fate of research projects performed during the research year by students enrolled in a Master's degree (MSc) of surgical science and to identify factors associated with subsequent publication. An anonymous online survey of 35 questions was sent to students enrolled in MSc of surgical science between 2013 and 2020. The questionnaire included student's characteristics, topic, and supervision of the research projects developed during the research year and dissemination of the research work. Data regarding publication was collected using PubMed database. Factors associated with publication were identified by univariate analysis. Among 361 students, 26% completed the survey. Among respondents, the publication rate of research projects was 53.7%. The median time interval between the end of the research year and the date of publication was 2 (1-3) years. The student was listed as a first author in 70.6% of publications. Factors associated with publication of the research work completed during the research year were student's previous publications (P = 0.041) and presentation of the research work in academic conferences (P = 0.005). The most mentioned cause for non-publication was the absence of completion of the research work. Among respondents, the publication rate of research works performed during the MSc was high, which emphasizes the quality of the work carried out by the students and their involvement. Significant efforts must be undertaken to encourage the enrollment of residents in scientific research. Supplementary Information: The online version contains supplementary material available at 10.1007/s40670-023-01973-y.

RESUMO

PURPOSE: The purpose of this study was to evaluate the capabilities of multiparametric magnetic resonance imaging (MRI) in differentiating between lipid-poor adrenal adenoma (LPAA) and adrenocortical carcinoma (ACC). MATERIALS AND METHODS: Patients of two centers who underwent surgical resection of LPAA or ACC after multiparametric MRI were retrospectively included. A training cohort was used to build a diagnostic algorithm obtained through recursive partitioning based on multiparametric MRI variables, including apparent diffusion coefficient and chemical shift signal ratio (i.e., tumor signal intensity index). The diagnostic performances of the multiparametric MRI-based algorithm were evaluated using a validation cohort, alone first and then in association with adrenal tumor size using a cut-off of 4 cm. Performances of the diagnostic algorithm for the diagnosis of ACC vs. LPAA were calculated using pathology as the reference standard. RESULTS: Fifty-four patients (27 with LPAA and 27 with ACC; 37 women; mean age, 48.5 ± 13.3 [standard deviation (SD)] years) were used as the training cohort and 61 patients (24 with LPAA and 37 with ACC; 47 women; mean age, 49 ± 11.7 [SD] years) were used as the validation cohort. In the validation cohort, the diagnostic algorithm yielded best accuracy for the diagnosis of ACC vs. LPAA (75%; 46/61; 95% CI: 55-88) when used without lesion size. Best sensitivity was obtained with the association of the diagnostic algorithm with tumor size (96%; 23/24; 95% CI: 80-99). Best specificity was obtained with the diagnostic algorithm used alone (76%; 28/37; 95% CI: 60-87). CONCLUSION: A multiparametric MRI-based diagnostic algorithm that includes apparent diffusion coefficient and tumor signal intensity index helps discriminate between ACC and LPAA with high degrees of specificity and accuracy. The association of the multiparametric MRI-based diagnostic algorithm with adrenal lesion size helps maximize the sensitivity of multiparametric MRI for the diagnosis of ACC.

RESUMO

BACKGROUND: Although the incidence of BTC is raising, national healthcare strategies to improve care lack. We aimed to explore patient clinical care pathways and strategies to improve biliary tract cancer (BTC) care. METHODS: We analysed the French National Healthcare database of all BTC inpatients between January 1, 2017 and December 31, 2021. Multinomial logistic regression adjusted odds ratios (aOR) were used to identify healthcare organisation factors that influenced access to curative care both overall and in a longitudinal sensibility analysis using optimal matching and hierarchical ascending classification to detect a subgroup of curative-care patients with a high survival over a two-year period. RESULTS: A total of 19,825 new BTC patients and three clinical care pathways (CCP) were identified: 'Palliative care' (PC-CCP), 'Non-curative Care' (NCC-CCP) and 'Curative Care' (CC-CCP) involving 7669 (38.7%), 7721 (38.9%) and 4435 (22.4%) patients respectively. Out of 1200 centers involved in BTC treatment, 84%, 11% and 5% were of low- (<15 patients/year), medium- (15-30 patients/year) and high-volume (>30 patients/year) respectively. Among patient, tumor and hospital factors, BTC management in academic (aOR: 2.32; 95%CI: 1.98-2.71), private (2.51; 2.22-2.83), semi-private (2.25; 1.91-2.65) and in high- (2.09; 1.81-2.42) or medium-volume (1.49; 1.33-1.68) centers increased probability to CC-CCP. These results were maintained in a longitudinal cluster of 2363 (53%) CC-CCP patients presenting a higher two-year survival compared with the rest [96.4% (95.1; 97.6) vs. 38.8% (36.3; 41.4), log-rank p < 0.001]. CONCLUSIONS: Among factors subject to healthcare policy improvement, the volume and type of centers managing BTC strongly influenced access to curative care.

RESUMO

BACKGROUND: The study explores the role of liver debulking surgery in cases of unresectable colorectal liver metastases (CRLM), challenging the traditional notion that surgery is not a valid option in such scenarios. MATERIALS AND METHODS: Patients with advanced but resectable disease who underwent surgery with a curative intent (Group I) and those with advanced incompletely resectable disease who underwent a "debulking" hepatectomy (Group II) were compared. RESULTS: There was no difference in the intra-operative and post-operative results between the two groups. The 3-year and 5-year OS rates were 69% and 47% for group 1 vs 64% and 35% for group 2 respectively (p = 0.14). The 3-year and 5-year PFS rates were 32% and 21% for group 1 vs 12% and 8% for group 2 respectively (p = 0.009). Independent predictors of PFS in the debulking group were bilobar metastases (HR = 2.70; p = 0.02); the presence of extrahepatic metastasis (HR = 2.65, p = 0.03) and the presence of more than 9 metastases (HR = 2.37; p = 0.04). Iterative liver surgery for CRLM was a significant protective factor (HR = 0.34, p = 0.04). CONCLUSION: An aggressive palliative surgical approach may offer a survival benefit for selected patients with unresectable CRLM, without increasing the morbidity. The decision for surgery should be made on a case-by-case basis.

RESUMO

BACKGROUND: Optimal management of colorectal liver metastasis (CRLM) is based on a combination of chemotherapy and surgical resection. The tumor regression grade (TRG) score is a histological scoring system to evaluate response to chemotherapy. The prognosis of a heterogeneous response in cases of multiple metastases has not been evaluated according to the TRG score. PATIENTS AND METHODS: All patients who underwent liver resection for multiple CRLM after neoadjuvant chemotherapy in two tertiary centers from January 2015 to April 2019 were retrospectively included. Oncological characteristics and outcome between TRG 1-2-3 (good response group), TRG 4-5 (poor response group) and heterogeneous TRG (good and poor TRG among different lesions within the same patient) groups were compared. RESULTS: Among the 327 patients included, 134 (41.0%) had good response (TRG 1-2-3), 120 (36.7%) had poor response (TRG 4-5), and 73 (22.3%) had heterogeneous response. The type and number of cycles of chemotherapy, k-Ras mutational status, and tumor number or size did not differ between the three groups. Use of irinotecan-based and anti-VEGF neoadjuvant therapy was associated with better TRG response [irinotecan-based: hazard ratio (OR) = 1.744; p = 0.045; anti-VEGF neoadjuvant therapy: 2.054; p = 0.005). Overall survival (OS) was higher in the 1-2-3 TRG group than in the heterogeneous TRG group (2-year OS = 81.3% vs. 60.3%, respectively; p = 0.003) and the 4-5 TRG group (2-year OS = 81.3% vs. 55.0%, respectively; p = 0.012) and similar between the heterogeneous and 4-5 TRG groups. CONCLUSIONS: The proportion of heterogeneous pathological response according to TRG is 22.3%, and the prognosis is comparable to that of poor pathological response.

RESUMO

BACKGROUND: There are no data to evaluate the difference in populations and impact of centers with liver transplant programs in performing laparoscopic liver resection (LLR). METHODS: This was a multicenter study including patients undergoing LLR for benign and malignant tumors at 27 French centers from 1996 to 2018. The main outcomes were postoperative severe morbidity and mortality. RESULTS: A total of 3154 patients were included, and 14 centers were classified as transplant centers (N = 2167 patients, 68.7 %). The transplant centers performed more difficult LLRs and more resections for hepatocellular carcinoma (HCC) in patients who more frequently had cirrhosis. A higher rate of performing the Pringle maneuver, a lower rate of blood loss and a higher rate of open conversion (all p < 0.05) were observed in the transplant centers. There was no association between the presence of a liver transplant program and either postoperative severe morbidity (<10 % in each group; p = 0.228) or mortality (1 % in each group; p = 0.915). CONCLUSIONS: Most HCCs, difficult LLRs, and cirrhotic patients are treated in transplant centers. We show that all centers can achieve comparable safety and quality of care in LLR independent of the presence of a liver transplant program.

RESUMO

BACKGROUND: C-reactive protein is a useful biological tool to predict infectious complications, but its predictive value in detecting organ-specific surgical site infection after liver resection has never been studied. We aimed to evaluate the predictive value of c-reactive protein and determine the cut-off values to detect postoperative liver resection-surgical site infection. METHODS: A multicentric analysis of consecutive patients with liver resection between 2018 and 2021 was performed. The predictive value of postoperative day 1, postoperative day 3, and postoperative day 5 C-reactive protein levels was evaluated using the area under the receiver operating characteristic curve. Cut-off values were determined using the Youden index in a 500-fold bootstrap resampling of 500 patients treated at 3 centers, who comprised the development cohort and were tested in an external independent validation cohort of 166 patients at a fourth center. RESULTS: Among the 500 patients who underwent liver resection of the development cohort, liver resection-surgical site infection occurred in 66 patients (13.2%), and the median time to diagnosis was 6.0 days (interquartile range, 4.0-9.0) days. Median C-reactive protein levels were significantly higher on postoperative day 1, postoperative day 3, and postoperative day 5 in the liver resection-surgical site infection group compared with the non-surgical site infection group (50.5 vs 34.5 ng/mL, 148.0 vs 72.5 ng/mL, and 128.4 vs 35.2 ng/mL, respectively; P < .001). Postoperative day 3 and postoperative day 5 C-reactive protein-level area under the curve values were 0.76 (95% confidence interval, 0.64-0.88, P < .001) and 0.82 (95% confidence interval, 0.72-0.92, P < .001), respectively. Postoperative day 3 and postoperative day 5 optimal cut-off values of 100 mg/L and 87.0 mg/L could be used to rule out liver resection-surgical site infection, with a negative predictive value of 87.0% (interquartile range, 70.2-93.8) and 76.0% (interquartile range, 65.0-88.0), respectively, in the validation cohort. CONCLUSION: Postoperative day 3 and postoperative day 5 C-reactive protein levels may be valuable predictive tools for liver resection-surgical site infection and aid in hospital discharge decision-making in the absence of other liver-related complications.

RESUMO

OBJECTIVE: To identify the factors associated with readmission after pancreatectomy for cancer and to assess their impact on the 1-year mortality in a French multicentric population. BACKGROUND: Pancreatectomy is a complex procedure with high morbidity that increases the length of hospital stay and jeopardizes survival. Hospital readmissions lead to increased health system costs, making this a topic of great interest. METHODS: Data collected from patients who underwent pancreatectomy for cancer between 2011 and 2019 were extracted from a French national medico-administrative database. A descriptive analysis was conducted to evaluate the association of baseline variables, including age, sex, liver-related comorbidities, Charlson Comorbidity Index, tumor localization, and use of neoadjuvant therapy, along with hospital type and volume, with readmission status. Centers were divided into low and high volumes according to the cutoff of 26 cases/year. Logistic regression models were developed to determine whether the identified bivariate associations persisted after adjusting for the patient characteristics. The mortality rates during readmission and at 1 year postoperatively were also determined. RESULTS: Of 22,935 patients who underwent pancreatectomy, 9129 (39.3%) were readmitted within 6 months. Readmission rates by year did not vary over the study period, and mean readmissions occurred within 20 days after discharge. Multivariate analysis showed that male sex [odds ratio (OR) = 1.12], age >70 years (OR = 1.16), comorbidities (OR = 1.21), distal pancreatectomy (OR = 1.11), and major postoperative complications (OR = 1.37) were predictors of readmission. Interestingly, readmission and surgery in low-volume centers increased the risk of death at 1 year by a factor of 2.15 [(2.01-2.31), P < 0.001] and 1.31 [(1.17-1.47), P < 0.001], respectively. CONCLUSIONS: Readmission after pancreatectomy for cancer is high with an increased rate of 1-year mortality.

RESUMO

BACKGROUND: Combined hepatocholangiocarcinoma is a rare cancer with a grim prognosis composed of both hepatocellular carcinoma and intrahepatic cholangiocarcinoma morphologic patterns in the same tumor. The aim of this multicenter, international cohort study was to compare the oncologic outcomes after surgery of combined hepatocholangiocarcinoma to hepatocellular carcinoma and intrahepatic cholangiocarcinoma. METHODS: Patients treated by surgery for combined hepatocholangiocarcinoma, hepatocellular carcinoma, and intrahepatic cholangiocarcinoma from 2000 to 2021 from multicenter international databases were analyzed retrospectively. Patients with combined hepatocholangiocarcinoma (cases) were compared with 2 control groups of hepatocellular carcinoma or intrahepatic cholangiocarcinoma, sequentially matched using a propensity score based on 8 preoperative characteristics. Overall and disease-free survival were compared, and predictors of mortality and recurrence were analyzed with Cox regression after propensity score matching. RESULTS: During the study period, 3,196 patients were included. Propensity score adjustment and 2 sequential matching processes produced a new cohort (n = 244) comprising 3 balanced groups was obtained (combined hepatocholangiocarcinoma = 56, intrahepatic cholangiocarcinoma = 66, and hepatocellular carcinoma = 122). Kaplan-Meier overall survival estimations at 1, 3, and 5 years were 67%, 45%, and 28% for combined hepatocholangiocarcinoma, 92%, 75%, and 55% for hepatocellular carcinoma, and 86%, 53%, and 42% for the intrahepatic cholangiocarcinoma group, respectively (P = .0014). Estimations of disease-free survival at 1, 3, and 5 years were 51%, 25%, and 17% for combined hepatocholangiocarcinoma, 63%, 35%, and 26% for the hepatocellular carcinoma group, and 51%, 31%, and 28% for the intrahepatic cholangiocarcinoma group, respectively (P = .19). Predictors of mortality were combined hepatocholangiocarcinoma subtype, metabolic syndrome, preoperative tumor markers alpha-fetoprotein and carbohydrate antigen 19-9, and satellite nodules, and recurrence was associated with satellite nodules rather than cancer subtype. CONCLUSION: Despite data limitations, overall survival among patients with combined hepatocholangiocarcinoma was worse than both groups and closer intrahepatic cholangiocarcinoma, whereas disease-free survival was similar among the 3 groups. Future research on immunophenotypic profiling may hold more promise than traditional nonmodifiable clinical characteristics (as found in this study) in predicting recurrence or response to salvage treatments.

RESUMO

BACKGROUND: Two-stage hepatectomy (TSH) has increased the chance of surgical resections for bilobar colorectal liver metastases (CRLM). Nevertheless, drop-out between stages and early recurrence rates raise the question of surgical futility in some situations. This study aimed to identify factors of TSH oncological failure. METHODS: Patients with bilobar CRLM eligible for TSH in three tertiary centers between 2010 and 2021 were included, and divided in Failure and Success groups. Oncological failure was defined as failure of the second stage hepatectomy for tumor progression or recurrence within 6 months after resection. RESULTS: Among 95 patients, 18 (18.9%) had hepatic progression between the two stages, and 7 (7.4%) failed to complete the second stage hepatectomy. After TSH, 31 (32.6%) patients experienced early recurrence. Overall, 38 (40.0%) patients experienced oncological failure (Failure group). The Failure group had lower median DFS (3 vs. 32 months, p < 0.001) and median OS (29 vs. 70 months, p = 0.045) than the Success group. On multivariable analysis, progression between the two stages in the future liver remnant (OR = 15.0 (3.22-113.0), p = 0.002), and maximal tumor size ≥40 mm in the future liver remnant (OR = 13.1 (2.12-117.0), p = 0.009) were independent factors of oncological failure. CONCLUSION: Recurrence between the two stages and maximal tumor size ≥40 mm in the future liver remnant were associated with TSH failure for patients with bilobar CRLM.

RESUMO

BACKGROUND: Solid benign liver lesions (BLL) are increasingly discovered, but clear indications for surgical treatment are often lacking. Concomitantly, laparoscopic liver surgery is increasingly performed. The aim of this study was to assess if the availability of laparoscopic surgery has had an impact on the characteristics and perioperative outcomes of patients with BLL. METHODS: This is a retrospective international multicenter cohort study, including patients undergoing a laparoscopic or open liver resection for BLL from 19 centers in eight countries. Patients were divided according to the time period in which they underwent surgery (2008-2013, 2014-2016, and 2017-2019). Unadjusted and risk-adjusted (using logistic regression) time-trend analyses were performed. The primary outcome was textbook outcome (TOLS), defined as the absence of intraoperative incidents ≥ grade 2, bile leak ≥ grade B, severe complications, readmission and 90-day or in-hospital mortality, with the absence of a prolonged length of stay added to define TOLS+. RESULTS: In the complete dataset comprised of patients that underwent liver surgery for all indications, the proportion of patients undergoing liver surgery for benign disease remained stable (12.6% in the first time period, 11.9% in the second time period and 12.1% in the last time period, p = 0.454). Overall, 845 patients undergoing a liver resection for BLL in the first (n = 374), second (n = 258) or third time period (n = 213) were included. The rates of ASA-scores≥3 (9.9%-16%,p < 0.001), laparoscopic surgery (57.8%-77%,p < 0.001), and Pringle maneuver use (33.2%-47.2%,p = 0.001) increased, whereas the length of stay decreased (5 to 4 days,p < 0.001). There were no significant changes in the TOLS rate (86.6%-81.3%,p = 0.151), while the TOLS + rate increased from 41.7% to 58.7% (p < 0.001). The latter result was confirmed in the risk-adjusted analyses (aOR 1.849,p = 0.004). CONCLUSION: The surgical treatment of BLL has evolved with an increased implementation of the laparoscopic approach and a decreased length of stay. This evolution was paralleled by stable TOLS rates above 80% and an increase in the TOLS + rate.

RESUMO

BACKGROUND AND STUDY AIMS: Laparoscopic approach of perihilar cholangiocarcinoma (PHC) is still challenging. We report the original use of a endoscopic hepaticogastrostomy (EHG) for definite biliary drainage in order to avoid biliary reconstruction. PATIENTS AND METHODS: A 70-year-old man presenting with jaundice was referred for resection of a Bismuth type IIIa PHC. Repeated endoscopic retrograde cholangiopancreatography failed to drain the future liver remnant, enabling only right anterior liver section drainage. EHG was performed three weeks before surgery. A hepatogastric anastomosis was created, placing a half-coated self-expanding endoprosthesis between biliary duct of segment 2 and the lesser gastric curvature. RESULTS: A laparoscopic right hepatectomy extended to segment 1, common bile duct, and hepatic pedicle lymphadenectomy was performed. The left hepatic duct was sectioned and ligated downstream to the biliary confluence of segment 2-3 and 4 allowing exclusive biliary flow through the EHG. The patient was disease free at 12 months, postoperative outcomes were uneventful except three readmissions for acute cholangitis due to prosthesis obstruction. CONCLUSIONS: EHG may be used as definite biliary drainage technique in laparoscopic PHC resection, at the expense of prosthesis obstruction and cholangitis.

RESUMO

IMPORTANCE: Imaging has demonstrated capabilities in the diagnosis of pancreatic neuroendocrine tumors (pNETs), but its utility for prognostic prediction has not been elucidated yet. OBJECTIVE: The aim of this study was to build a radiomics model using preoperative computed tomography (CT) data that may help predict recurrence-free survival (RFS) or OS in patients with pNET. DESIGN: We performed a retrospective observational study in a cohort of French patients with pNETs. PARTICIPANTS: Patients with surgically resected pNET and available CT examinations were included. INTERVENTIONS: Radiomics features of preoperative CT data were extracted using 3D-Slicer® software with manual segmentation. Discriminant features were selected with penalized regression using least absolute shrinkage and selection operator method with training on the tumor Ki67 rate (≤2 or >2). Selected features were used to build a radiomics index ranging from 0 to 1. OUTCOME AND MEASURE: A receiving operator curve was built to select an optimal cutoff value of the radiomics index to predict patient RFS and OS. Recurrence-free survival and OS were assessed using Kaplan-Meier analysis. RESULTS: Thirty-seven patients (median age, 61 years; 20 men) with 37 pNETs (grade 1, 21/37 [57%]; grade 2, 12/37 [32%]; grade 3, 4/37 [11%]) were included. Patients with a radiomics index >0.4 had a shorter median RFS (36 months; range: 1-133) than those with a radiomics index ≤0.4 (84 months; range: 9-148; P = .013). No associations were found between the radiomics index and OS (P = .86).

RESUMO

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver tumor after hepatocellular carcinoma (HCC). Management depends on their resectability at the time of diagnosis. Two types can be distinguished by imaging: resectable ICCs amenable to surgery and locally advanced and/or metastatic ICCs, that are treated by chemotherapy, radiotherapy or loco-regional treatment (radioembolization, chemoembolization, intra-arterial chemotherapy and thermoablation). Over the last decade, the management strategy for these tumors has been modified by the appearance of loco-regional treatments as well as the introduction of immunotherapy that have shown their efficacy in the control of ICC. The aim of this review is to describe the current status of treatments for ICCs, as well as the different therapeutic strategies being assessed.

RESUMO

The SARS-COV-2 pandemic disrupted healthcare systems. We assessed its impact on the presentation, care trajectories and outcomes of new pancreatic cancers (PCs) in the Paris area. We performed a retrospective multicenter cohort study on the data warehouse of Greater Paris University Hospitals (AP-HP). We identified all patients newly referred with a PC between January 1, 2019, and June 30, 2021, and excluded endocrine tumors. Using claims data and health records, we analyzed the timeline of care trajectories, the initial tumor stage, the treatment categories: pancreatectomy, exclusive systemic therapy or exclusive best supportive care (BSC). We calculated patients' 1-year overall survival (OS) and compared indicators in 2019 and 2020 to 2021. We included 2335 patients. Referral fell by 29% during the first lockdown. The median time from biopsy and from first MDM to treatment were 25 days (16-50) and 21 days (11-40), respectively. Between 2019 and 2020 to 2021, the rate of metastatic tumors (36% vs 33%, P = .39), the pTNM distribution of the 464 cases with upfront tumor resection (P = .80), and the proportion of treatment categories did not vary: tumor resection (32% vs 33%), exclusive systemic therapy (49% vs 49%), exclusive BSC (19% vs 19%). The 1-year OS rates in 2019 vs 2020 to 2021 were 92% vs 89% (aHR = 1.42; 95% CI, 0.82-2.48), 52% vs 56% (aHR = 0.88; 95% CI, 0.73-1.08), 13% vs 10% (aHR = 1.00; 95% CI, 0.78-1.25), in the treatment categories, respectively. Despite an initial decrease in the number of new PCs, we did not observe any stage shift. OS did not vary significantly.

RESUMO

BACKGROUND: Posthepatectomy liver failure (PHLF) contributes significantly to morbidity and mortality after liver surgery. Standardized assessment of preoperative liver function is crucial to identify patients at risk. These European consensus guidelines provide guidance for preoperative patient assessment. METHODS: A modified Delphi approach was used to achieve consensus. The expert panel consisted of hepatobiliary surgeons, radiologists, nuclear medicine specialists, and hepatologists. The guideline process was supervised by a methodologist and reviewed by a patient representative. A systematic literature search was performed in PubMed/MEDLINE, the Cochrane library, and the WHO International Clinical Trials Registry. Evidence assessment and statement development followed Scottish Intercollegiate Guidelines Network methodology. RESULTS: Based on 271 publications covering 4 key areas, 21 statements (at least 85 per cent agreement) were produced (median level of evidence 2- to 2+). Only a few systematic reviews (2++) and one RCT (1+) were identified. Preoperative liver function assessment should be considered before complex resections, and in patients with suspected or known underlying liver disease, or chemotherapy-associated or drug-induced liver injury. Clinical assessment and blood-based scores reflecting liver function or portal hypertension (for example albumin/bilirubin, platelet count) aid in identifying risk of PHLF. Volumetry of the future liver remnant represents the foundation for assessment, and can be combined with indocyanine green clearance or LiMAx® according to local expertise and availability. Functional MRI and liver scintigraphy are alternatives, combining FLR volume and function in one examination. CONCLUSION: These guidelines reflect established methods to assess preoperative liver function and PHLF risk, and have uncovered evidence gaps of interest for future research.


Liver surgery is an effective treatment for liver tumours. Liver failure is a major problem in patients with a poor liver quality or having large operations. The treatment options for liver failure are limited, with high death rates. To estimate patient risk, assessing liver function before surgery is important. Many methods exist for this purpose, including functional, blood, and imaging tests. This guideline summarizes the available literature and expert opinions, and aids clinicians in planning safe liver surgery.

RESUMO

Surgical resection of adrenocortical carcinoma (ACC) is the only curative treatment. Even in localized (I-II) stages, open adrenalectomy (OA) is the gold standard, though laparoscopic adrenalectomy (LA) can be proposed in selected patients. Despite the postoperative benefits of LA, its role in the surgical management of patients with ACC remains controversial regarding oncologic outcomes. The aim of this retrospective study was to compare the outcomes of patients with localized ACC submitted to LA or OA in a referral center from 1995 to 2020. Among 180 consecutive patients operated on for ACC, 49 presented with localized ACC (19 LA and 30 OA). Baseline characteristics were similar between groups, except for tumor size. Kaplan-Meier estimates of 5-year overall survival were similar in both groups (p = 0.166) but 3-year disease-free survival was in favor of OA (p = 0.020). Though LA could be proposed in highly selected patients, OA should still be considered the standard approach in patients with known or suspected localized ACC.
