RESUMEN
BACKGROUND: Minimally invasive surgery has gained momentum for left pancreatic resections. However, debate remains about whether it has any advantage over open surgery for distal pancreatectomy for pancreatic neuroendocrine tumors. METHODS: This retrospective review examined pancreatectomies performed for resectable pancreatic neuroendocrine tumors at 21 centers in France between January 2014 and December 2018. Short and long-term outcomes were compared before and after propensity score matching based on tumor size, sex, age, body mass index, center, and method of pancreatic transection. RESULTS: During the period study, 274 patients underwent left pancreatic resection for pancreatic neuroendocrine tumors [109 underwent distal splenopancreatectomy, and 165 underwent spleen-preserving distal pancreatectomy [(splenic vessel preservation (n = 97; 58.7%)/splenic vessel resection (n = 68; 41.3%)]. Before propensity score matching, minimally invasive surgery was associated with a lower rate of major morbidity (P = .004), lower rate of postoperative delayed gastric emptying (P = .04), and higher rate of "textbook" outcomes (P = .04). After propensity score matching, there were 2 groups of 54 patients (n = 30 distal splenopancreatectomy; n = 78 spleen-preserving distal pancreatectomy). Minimally invasive surgery was associated with less blood loss (P = .05), decreased rate of major morbidity (6% vs. 24%; P = .02), less delayed gastric emptying (P = .05) despite similar rates of postoperative fistula, hemorrhage, and reoperation (P > .05). The 5-year overall survival (79% vs. 75%; P = .74) and recurrence-free survival (10% vs 17%; P = .39) were similar. CONCLUSION: Minimally invasive surgery for left pancreatic resection can be safely proposed for patients with resectable left pancreatic neuroendocrine tumors. Minimally invasive surgery decreases the rate of major complications while providing comparable long-term oncologic outcomes.

BACKGROUND: The impact of cirrhosis on the postoperative outcomes of distal pancreatectomy is yet to be reported. We aimed to evaluate the outcomes of distal pancreatectomy in patients with cirrhosis. METHODS: We conducted a retrospective, multicentric study patients with cirrhosis who underwent planned distal pancreatectomy between 2008 and 2020 in French high volume centers. Patients with cirrhosis were matched 1:4 for demographic, surgical, and histologic criteria with patients without cirrhosis. The primary endpoint was severe morbidity (Clavien-Dindo grade ≥III). The secondary endpoints were postoperative complications, specifically related to cirrhosis and pancreatic surgery, and survival for patients with pancreatic adenocarcinoma. RESULTS: Overall, 32 patients with cirrhosis were matched with 128 patients without cirrhosis. Most patients (93.5%) had Child-Pugh A cirrhosis. The severe morbidity rate after distal pancreatectomy was higher in patients with cirrhosis than in those without cirrhosis (28.13% vs 25.75%, P = .11. The operative time was significantly longer in the cirrhotic group compared with controls (P = .01). However, patients with and without cirrhosis had comparable blood loss and conversion rates. Postoperatively, the two groups had similar rates of pancreatic fistula, hemorrhage, reoperation, postoperative mortality, and survival rates at 1, 3, and 5 years. CONCLUSION: The current study suggests that distal pancreatectomy in high-volume centers is feasible for patients with compensated cirrhosis.

BACKGROUND: Adjuvant chemotherapy (AC) improves the prognosis after pancreatic ductal adenocarcinoma (PDAC) resection. However, previous studies have shown that a large proportion of patients do not receive or complete AC. This national study examined the risk factors for the omission or interruption of AC. METHODS: Data of all patients who underwent pancreatic surgery for PDAC in France between January 2012 and December 2017 were extracted from the French National Administrative Database. We considered "omission of adjuvant chemotherapy" (OAC) all patients who failed to receive any course of gemcitabine within 12 postoperative weeks and "interruption of AC" (IAC) was defined as less than 18 courses of AC. RESULTS: A total of 11 599 patients were included in this study. Pancreaticoduodenectomy was the most common procedure (76.3%), and 31% of the patients experienced major postoperative complications. OACs and IACs affected 42% and 68% of the patients, respectively. Ultimately, only 18.6% of the cohort completed AC. Patients who underwent surgery in a high-volume centers were less affected by postoperative complications, with no impact on the likelihood of receiving AC. Multivariate analysis showed that age ≥ 80 years, Charlson comorbidity index (CCI) ≥ 4, and major complications were associated with OAC (OR = 2.19; CI95%[1.79-2.68]; OR = 1.75; CI95%[1.41-2.18] and OR = 2.37; CI95%[2.15-2.62] respectively). Moreover, age ≥ 80 years and CCI 2-3 or ≥ 4 were also independent risk factors for IAC (OR = 1.54, CI95%[1.1-2.15]; OR = 1.43, CI95%[1.21-1.68]; OR = 1.47, CI95%[1.02-2.12], respectively). CONCLUSION: Sequence surgery followed by chemotherapy is associated with a high dropout rate, especially in octogenarian and comorbid patients.

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. 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 nondilated 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 days). 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 (χ 2 test, P =0.73, ITT analysis). Absence of statistically significant difference persisted after adjustment for stratification variables and in per-protocol analysis. CONCLUSION: Continuous intravenous somatostatin is not statistically different from subcutaneous octreotide in the prevention of grade B/C POPF after pancreatectomy. FINDINGS: In the PREFIPS Randomized Clinical Trial including 651 patients, a total of 153 patients (23.5%) developed a grade B/C POPF with no significant difference between both groups: 24.1%: somatostatin arm and 22.9%: octreotide arm (χ 2 test, P =0.73, ITT analysis). Absence of statistically significant difference persisted after adjustment for stratification variables and in per-protocol analysis.

BACKGROUND & OBJECTIVES: Sarcopenia is a morbi-mortality risk factor in digestive surgery, though its impact after major hepatectomy (MH) remains unknown. This prospective pilot study investigated whether volume and function of a regenerating liver is influenced by body composition. METHODS: From 2011 to 2016, 125 consecutive patients had computed tomography and 99mTc-labelled-mebrofenin SPECT-scintigraphy before and after MH at day 7 and 1 month for measurements of liver volumes and functions. L3 vertebra muscle mass identified sarcopenia. Primary endpoint was the impact of sarcopenia on regeneration capacities (i.e. volume/function changes and post-hepatectomy liver failure (PHLF) rate). Secondary endpoint was 3-month morbi-mortality. RESULTS: Sarcopenic patients (SP; N = 69) were significantly older than non-sarcopenic (NSP), with lower BMI and more malignancies, but with comparable liver function/volume at baseline. Postoperatively, SP showed higher rates of ISGLS_PHLF (24.6 % vs 10.9 %; p = 0.05) but with comparable rates of severe morbidity (23.2 % vs 16.4 %; p = 0.35), overall (8.7 % vs 3.6 %; p = 0.3) and PHLF-related mortality (8,7 % vs 1.8 %; p = 0.075). After matching on the extent of resection or using propensity score, regeneration and PHLF rates were similar. CONCLUSION: This prospective study using first sequential SPECT-scintigraphy showed that sarcopenia by itself does not affect liver regeneration capacities and short-term postoperative course after MH.

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.

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.

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.

BACKGROUND & AIMS: Progresses in management make a higher proportion of cirrhotic patients with gastrointestinal (GI) cancer candidates to chemotherapy. Data are needed on the safety and liver-related events associated with the use of chemotherapy in these patients. METHODS: Forty-nine patients with cirrhosis receiving chemotherapy against GI cancer from 2013 to 2018 were identified in the French Health Insurance Database using ICD-10 codes K70-K74, and matched 1:2 to non-cirrhotic controls (n = 98) on age, tumour type and type of treatment. Adverse events (AE), dose tapering, discontinuation rate, liver-related events and survival rate were compared. RESULTS: Patients with cirrhosis (Child-Pugh A 91%) more often received lower doses (38.8% vs 7.1%, p < .001), without significant differences in terms of grade 3/4 AE or dose tapering rates (29.6% vs. 36.7%; 22.3% vs 24.4%, respectively). Treatment discontinuation rate was higher in patients with cirrhosis (23.3% vs. 11.3%, p = .005). Child-Pugh (p = .007) and MELD (p = .025) scores increased under chemotherapy. Five patients with cirrhosis (10.2%) had liver decompensation within 12 months, and 17.2% of deaths in the cirrhosis group were liver-related versus 0% in matched controls. WHO-PS stage > 1 (HR 3.74, CI95%: 2.13-6.57, p < .001), TNM-stage M1 (HR 3.61, CI 95%: 1.82-7.16, p < .001), non-colorectal cancer (HR 1.73, CI 95%: 1.05-2.86, p = .032) and bilirubin higher than 5 mg/dL (HR 2.26, CI 95%: 1.39-3.70, p < .001) were independent prognostic factors of 2-year mortality, whereas cirrhosis was not. CONCLUSIONS: Chemotherapy should be proposed only in patients with compensated cirrhosis with close monitoring of liver function. Dose management remains challenging. Multidisciplinary management is warranted to improve these patients' outcomes.

BACKGROUND AND AIMS: Alterations in liver histology influence the liver's capacity to regenerate, but the relevance of each of the different changes in rapid liver growth induction is unknown. This study aimed to analyze the influence of the degree of histological alterations during the first and second stages on the ability of the liver to regenerate. METHODS: This cohort study included data obtained from the International ALPPS Registry between November 2011 and October 2020. Only patients with colorectal liver metastases were included in the study. We developed a histological risk score based on histological changes (stages 1 and 2) and a tumor pathology score based on the histological factors associated with poor tumor prognosis. RESULTS: In total, 395 patients were included. The time to reach stage 2 was shorter in patients with a low histological risk stage 1 (13 vs 17 days, P Ë0.01), low histological risk stage 2 (13 vs 15 days, P <0.01), and low pathological tumor risk (13 vs 15 days, P <0.01). Regarding interval stage, there was a higher inverse correlation in high histological risk stage 1 group compared to low histological risk 1 group in relation with future liver remnant body weight ( r =-0.1 and r =-0.08, respectively), and future liver remnant ( r =-0.15 and r =-0.06, respectively). CONCLUSIONS: ALPPS is associated with increased histological alterations in the liver parenchyma. It seems that the more histological alterations present and the higher the number of poor prognostic factors in the tumor histology, the longer the time to reach the second stage.

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.

BACKGROUND/OBJECTIVES: Genetic counselling (GC) is a key step in the identification of inherited germline mutations. However, the oncogenetic practices are poorly described for pancreatic adenocarcinoma (PA) in Europe. The CAPANCOGEN study aimed to describe the GC referral practices in France and assess the implementation of international guidelines in patients with PA. METHODS: Information about GC referrals with PA was collected in 13 French centres from September 2019 to October 2021. In the 5 largest centres, personal and familial histories of cancers and diseases associated with a higher risk of germline mutations were collected in 460 patients, according to international, American, European and French GC referral guidelines. Univariate and multivariate logistic regression analysis were performed to identify the factors influencing GC referral. RESULTS: Among 833 patients, a total of 100 patients (12%) had an indication of GC according to local multidisciplinary tumour board meetings (MTBM). Among these patients, 41% did not undergo GC. The median time between MTBM and GC was 55 days (IQR: 14.5-112). Among 460 patients with collected personal and familial history, 31.5% were not referred to a GC despite an existing indication. In multivariate logistic regression analysis, suspected CDKN2A (p = 0.032) or BRCA mutation (p < 0.001), familial pancreatic cancer history (p < 0.001) and controlled disease with first-line platinum-based chemotherapy (p < 0.001) increased the referral rate. Conversely, older age (p = 0.002) and a locally advanced PA (p = 0.045) decreased the risk of GC referral. CONCLUSIONS: GC referral is inadequate despite valuable information in patients' medical files.

INTRODUCTION: Ampullary neuroendocrine neoplasia (NEN) is rare and evidence regarding their management is scarce. This study aimed to describe clinicopathological features, management, and prognosis of ampullary NEN according to their endoscopic or surgical management. METHODS: From a multi-institutional international database, patients treated with either endoscopic papillectomy (EP), transduodenal surgical ampullectomy (TSA), or pancreaticoduodenectomy (PD) for ampullary NEN were included. Clinical features, post-procedure complications, and recurrences were assessed. RESULTS: 65 patients were included, 20 (30.8%) treated with EP, 19 (29.2%) with TSA, and 26 (40%) with PD. Patients were mostly asymptomatic (n = 46; 70.8%). Median tumor size was 17 mm (12-22), tumors were mostly grade 1 (70.8%) and pT2 (55.4%). Two (10%) EP resulted in severe American Society for Gastrointestinal Enterology (ASGE) adverse post-procedure complications and 10 (50%) were R0. Clavien 3-5 complications did not occur after TSA and in 4, including 1 postoperative death (15.4%) of patients after PD, with 17 (89.5%) and 26 R0 resection (100%), respectively. The pN1/2 rate was 51.9% (n = 14) after PD. Tumor size larger than 1 cm (i.e., pT stage >1) was a predictor for R1 resection (p < 0.001). Three-year overall survival and disease-free survival after EP, TSA, and PD were 92%, 68%, 92% and 92%, 85%, 73%, respectively. CONCLUSION: Management of ampullary NEN is challenging. EP should not be performed in lesions larger than 1 cm or with a endoscopic ultrasonography T stage beyond T1. Local resection by TSA seems safe and feasible for lesions without nodal involvement. PD should be preferred for larger ampullary NEN at risk of nodal metastasis.

Background: Liver resection and local ablation are the only curative treatment for non-cirrhotic hepatocellular carcinoma (HCC). Few data exist concerning the prognosis of patients resected for non-cirrhotic HCC. The objectives of this study were to determine the prognostic factors of recurrence-free survival (RFS) and overall survival (OS) and to develop a prognostication algorithm for non-cirrhotic HCC. Methods: French multicenter retrospective study including HCC patients with non-cirrhotic liver without underlying viral hepatitis: F0, F1 or F2 fibrosis. Results: A total of 467 patients were included in 11 centers from 2010 to 2018. Non-cirrhotic liver had a fibrosis score of F0 (n=237, 50.7%), F1 (n=127, 27.2%) or F2 (n=103, 22.1%). OS and RFS at 5 years were 59.2% and 34.5%, respectively. In multivariate analysis, microvascular invasion and HCC differentiation were prognostic factors of OS and RFS and the number and size were prognostic factors of RFS (P<0.005). Stratification based on RFS provided an algorithm based on size (P=0.013) and number (P<0.001): 2 HCC with the largest nodule ≤10 cm (n=271, Group 1); 2 HCC with a nodule >10 cm (n=176, Group 2); >2 HCC regardless of size (n=20, Group 3). The 5-year RFS rates were 52.7% (Group 1), 30.1% (Group 2) and 5% (Group 3). Conclusions: We developed a prognostication algorithm based on the number (≤ or >2) and size (≤ or >10 cm), which could be used as a treatment decision support concerning the need for perioperative therapy. In case of bifocal HCC, surgery should not be a contraindication.
RESUMEN
BACKGROUND: It is unclear whether preoperative biliary drainage (PBD) by endoscopic retrograde cholangiopancreatography (ERCP) is equivalent to electrocautery-enhanced lumen-apposing metal stent (ECE-LAMS) before pancreatoduodenectomy (PD). METHODS: Patients who underwent PBD for distal malignant biliary obstruction (DMBO) followed by PD were retrospectively included in nine expert centers between 2015 and 2022. ERCP or endoscopic ultrasound-guided choledochoduodenostomy with ECE-LAMS were performed. In intent-to-treat analysis, patients drained with ECE-LAMS were considered the study group (first-LAMS group) and those drained with conventional transpapillary stent the control group (first-cannulation group). The rates of technical success, clinical success, drainage-related complications, surgical complications, and oncological outcomes were analyzed. RESULTS: Among 156 patients, 128 underwent ERCP and 28 ECE-LAMS in first intent. The technical and clinical success rates were 83.5% and 70.2% in the first-cannulation group versus 100% and 89.3% in the first-LAMS group (p = 0.02 and p = 0.05, respectively). The overall complication rate over the entire patient journey was 93.7% in first-cannulation group versus 92.0% in first-LAMS group (p = 0.04). The overall endoscopic complication rate was 30.5% in first-cannulation group versus 17.9% in first-LAMS group (p = 0.25). The overall complication rate after PD was higher in the first-cannulation group than in the first-LAMS group (92.2% versus 75.0%, p = 0.016). Overall survival and progression-free survival did not differ between the groups. CONCLUSIONS: PBD with ECE-LAMS is easier to deploy and more efficient than ERCP in patients with DMBO. It is associated with less surgical complications after pancreatoduodenectomy without compromising the oncological outcome.

BACKGROUND: This study aimed to analyze the predictive value of Hepatobiliary scintigraphy (HBS) for posthepatectomy liver failure (PHLF) after major liver resection with a comparison to assessment of liver volume in a multicenter cohort. METHODS: Patients who underwent liver resection after HBS were included from six centers. Remnant liver volume was calculated from CT images. PHLF was scored and graded according to the grade B/C ISGLS criteria. RESULTS: In 547 patients PHLF incidence was 10% (56/547) and 90-day mortality rate 8% (42/547). Overall predictive value of remnant liver function was 0.66 (0.58-0.74) and similar to that of remnant volume (0.63 (0.72). For biliary tumors, a function cut-off of 2.7%/min/m2 and 30% volume cut-off resulted in a PHLF rate 12% and 13%, respectively. While an 8.5%/min (4.5%/min/m2) function cut-off resulted in 7% PHLF for those with a function above the cutoff while a 40% volume cutoff still resulted in 14% PHLF rate. In the multivariable analyses for PHLF, liver function was predictive but liver volume was not. CONCLUSION: The current study shows that preoperative liver function assessment using HBS is at least as predictive for PHLF as liver volume assessment, and likely has several advantages, particularly in the high-risk sub-group of biliary tumors.

BACKGROUND: The field of robotic liver resection (RLR) has developed in the past decades. This technique seems to improve the access to the posterosuperior (PS) segments. Evidence of a possible advantage over transthoracic laparoscopy (TTL) is not yet available. We aimed to compare RLR to TTL for tumors located in the PS segments of the liver in terms of feasibility, difficulty scoring, and outcome. METHODS: This retrospective study compared patients undergoing robotic liver resections and transthoracic laparoscopic resections of the PS segments between January 2016 and December 2022 in a high-volume HPB center. Patients' characteristics, perioperative outcomes, and postoperative complications were evaluated. RESULTS: In total, 30 RLR and 16 TTL were included. Only wedge resections were performed in the TTL group, while 43% of the patients in the RLR group had an anatomical resection (p < 0.001). The difficulty score according to the IWATE difficulty scoring system was significantly higher in the RLR group (p < 0.001). Total operative time was similar between the two groups. Complication rates, either overall or major, were comparable between the two techniques and hospital stay was significantly shorter in the RLR group. Patients in the TTL group were found to have more pulmonary complications (p = 0.01). CONCLUSION: RLR may provide some advantages over TTL for the resection of tumors located in the PS segments.

OBJECTIVE: This survey sought to appraise the degree of consistency in the management of disappeared colorectal liver metastases (dCRLM) among liver surgeons in different countries. BACKGROUND: Colorectal liver metastases (CRLM) account for half of the deaths secondary to colorectal cancer. Due to the high utilization of chemotherapy before surgery, some or all CRLM can disappear (dCRLM) but management of dCRLMs remains unclear. METHODS: Seven simulated scenarios of dCRLM were presented to experienced liver surgeons using an online platform. Treatment decisions were submitted and analysed using the multi-rater kappa method. The effect of the experience, complexity of scenarios, and location and number of dCRLM on treatment decision were analysed. RESULTS: Sixty-seven liver surgeons from 25 countries completed the survey. There was no agreement about the therapeutic strategies of dCRLM in all scenarios (kappa 0.12, IQR 0.20-0.32). In scenarios with lower difficulty scores, surgeons tended to offer surgical resection for dCRLM alongside the visible CRLM (vCRLM), however, with poor agreement (kappa 0.32, IQR 0.19-0.51). No agreement was seen for clinical scenario in which all CRLM lesions disappeared (kappa 0.20). CONCLUSION: There are clear inconsistencies in the management decisions of dCRLM. Better evidence is required to define optimal management strategies.
