Feasibility and Short-Term Outcomes in Liver-First Approach: A Spanish Snapshot Study (the RENACI Project). Cancers (Basel) 2024; 16:1676. [PMID: 38730631 PMCID: PMC11082946 DOI: 10.3390/cancers16091676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 04/21/2024] [Accepted: 04/25/2024] [Indexed: 05/13/2024] Open
Abstract
(1) Background: The liver-first approach may be indicated for colorectal cancer patients with synchronous liver metastases to whom preoperative chemotherapy opens a potential window in which liver resection may be undertaken. This study aims to present the data of feasibility and short-term outcomes in the liver-first approach. (2) Methods: A prospective observational study was performed in Spanish hospitals that had a medium/high-volume of HPB surgeries from 1 June 2019 to 31 August 2020. (3) Results: In total, 40 hospitals participated, including a total of 2288 hepatectomies, 1350 for colorectal liver metastases, 150 of them (11.1%) using the liver-first approach, 63 (42.0%) in hospitals performing <50 hepatectomies/year. The proportion of patients as ASA III was significantly higher in centers performing ≥50 hepatectomies/year (difference: 18.9%; p = 0.0213). In 81.1% of the cases, the primary tumor was in the rectum or sigmoid colon. In total, 40% of the patients underwent major hepatectomies. The surgical approach was open surgery in 87 (58.0%) patients. Resection margins were R0 in 78.5% of the patients. In total, 40 (26.7%) patients had complications after the liver resection and 36 (27.3%) had complications after the primary resection. One-hundred and thirty-two (89.3%) patients completed the therapeutic regime. (4) Conclusions: There were no differences in the surgical outcomes between the centers performing <50 and ≥50 hepatectomies/year. Further analysis evaluating factors associated with clinical outcomes and determining the best candidates for this approach will be subsequently conducted.

Short- and long-term outcomes after distal pancreatectomy with radiologic infiltration of splenic vessels for pancreatic ductal adenocarcinoma. J Gastrointest Surg 2024; 28:467-473. [PMID: 38583897 DOI: 10.1016/j.gassur.2024.01.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 12/22/2023] [Accepted: 01/13/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND The effect of radiologic splenic vessels involvement (RSVI) on the survival of patients with pancreatic adenocarcinoma (PAC) located in the body and tail of the pancreas is controversial, and its influence on postoperative morbidity after distal pancreatectomy (DP) is unknown. This study aimed to determine the influence of RSVI on postoperative complications, overall survival (OS), and disease-free survival (DFS) in patients undergoing DP for PAC. METHODS A multicenter retrospective study of DP was conducted at 7 hepatopancreatobiliary units between January 2008 and December 2018. Patients were classified according to the presence of RSVI. A Clavien-Dindo grade of >II was considered to represent a major complication. RESULTS A total of 95 patients were included in the analysis. Moreover, 47 patients had vascular infiltration: 4 had arterial involvement, 10 had venous involvement, and 33 had both arterial and venous involvements. The rates of major complications were 20.8% in patients without RSVI, 40.0% in those with venous RSVI, 25.0% in those with arterial RSVI, and 30.3% in those with both arterial and venous RSVIs (P = .024). The DFS rates at 3 years were 56% in the group without RSVI, 50% in the group with arterial RSVI, and 16% in the group with both arterial and venous RSVIs (P = .003). The OS rates at 3 years were 66% in the group without RSVI, 50% in the group with arterial RSVI, and 29% in the group with both arterial and venous RSVIs (P < .0001). CONCLUSION RSVI increased the major complication rates after DP and reduced the OS and DFS. Therefore, it may be a useful prognostic marker in patients with PAC scheduled to undergo DP and may help to select patients likely to benefit from neoadjuvant treatment.

Abstract
BACKGROUND Textbook outcome is an interesting quality metrics tool. Information on textbook outcomes in distal pancreatectomy is very scarce. In this study we determined textbook outcome in a distal pancreatectomy multicenter database and propose a specific definition of textbook outcome-distal pancreatectomy that includes pancreatic fistula. METHODS Retrospective multicenter observational study of distal pancreatectomy performed at 8 hepatopancreatobiliary surgery units from January 1, 2008, to December 31, 2018. The inclusion criteria were any scheduled distal pancreatectomy performed for any diagnosis and age > 18 years. Specific textbook outcome-distal pancreatectomy was defined as hospital stay P < 75, no Clavien-Dindo complications (≥ III), no hospital mortality, and no readmission recorded at 90 days, and the absence of pancreatic fistula (B/C). RESULTS Of the 450 patients included, 262 (58.2%) obtained textbook outcomes. Prolonged stay was the parameter most frequently associated with failure to achieve textbook outcomes. The textbook outcome group presented the following results. Preoperative: lower American Society of Anesthesiologists score < III, a lower percentage of smokers, and less frequent tumor invasion of neighboring organs or vascular invasion; operative: major laparoscopic approach, and less resection of neighboring organs and less operative transfusion; postoperative: lower percentage of delayed gastric emptying and pancreatic fistula B/C, and diagnosis other an adenocarcinoma. In the multivariate study, the American Society of Anesthesiologists score > II, resection of neighboring organs, B/C pancreatic fistula, and delayed gastric emptying were associated with failure to achieve textbook outcomes. CONCLUSION The textbook outcome rate in our 450 pancreaticoduodenectomies was 58.2%. In the multivariate analysis, the causes of failure to achieve textbook outcomes were American Society of Anesthesiologists score > II, resection of neighboring organs, pancreatic fistula B/C, and delayed gastric emptying. We believe that pancreatic fistula should be added to the specific definition of textbook outcome-distal pancreatectomy because it is the most frequent complication of this procedure.

Repeated pancreatic resection for pancreatic metastases from renal cell Carcinoma: A Spanish multicenter study (PANMEKID). Surg Oncol 2024; 52:102039. [PMID: 38301449 DOI: 10.1016/j.suronc.2024.102039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 01/20/2024] [Indexed: 02/03/2024]
Abstract
BACKGROUND AND OBJECTIVES Recurrent isolated pancreatic metastasis from Renal Cell Carcinoma (RCC) after pancreatic resection is rare. The purpose of our study is to describe a series of cases of relapse of pancreatic metastasis from renal cancer in the pancreatic remnant and its surgical treatment with a repeated pancreatic resection, and to analyse the results of both overall and disease-free survival. METHODS Multicenter retrospective study of patients undergoing pancreatic resection for RCC pancreatic metastases, from January 2010 to May 2020. Patients were grouped into two groups depending on whether they received a single pancreatic resection (SPS) or iterative pancreatic resection. Data on short and long-term outcome after pancreatic resection were collected. RESULTS The study included 131 pancreatic resections performed in 116 patients. Thus, iterative pancreatic surgery (IPS) was performed in 15 patients. The mean length of time between the first pancreatic surgery and the second was 48.9 months (95 % CI: 22.2-56.9). There were no differences in the rate of postoperative complications. The DFS rates at 1, 3 and 5 years were 86 %, 78 % and 78 % vs 75 %, 50 % and 37 % in the IPS and SPS group respectively (p = 0.179). OS rates at 1, 3, 5 and 7 years were 100 %, 100 %, 100 % and 75 % in the IPS group vs 95 %, 85 %, 80 % and 68 % in the SPS group (p = 0.895). CONCLUSION Repeated pancreatic resection in case of relapse of pancreatic metastasis of RCC in the pancreatic remnant is justified, since it achieves OS results similar to those obtained after the first resection.

Evaluation of the validated intraoperative bleeding scale in liver surgery: study protocol for a multicenter prospective study. Front Surg 2023; 10:1223225. [PMID: 37850041 PMCID: PMC10577188 DOI: 10.3389/fsurg.2023.1223225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 09/18/2023] [Indexed: 10/19/2023] Open
Abstract
Background Surgical hemostasis has become one of the key principles in the advancement of surgery. Hemostatic agents are commonly administered in many surgical specialties, although the lack of consensus on the definition of intraoperative bleeding or of a standardized system for its classification means that often the most suitable agent is not selected. The recommendations of international organizations highlight the need for a bleeding severity scale, validated in clinical studies, that would allow the selection of the best hemostatic agent in each case. The primary objective of this study is to evaluate the VIBe scale (Validated Intraoperative Bleeding Scale) in humans. Secondary objectives are to evaluate the scale's usefulness in liver surgery; to determine the relationship between the extent of bleeding and the hemostatic agent used; and to assess the relationship between the grade of bleeding and postoperative complications. Methods Prospective multicenter observational study including 259 liver resections that meet the inclusion criteria: patients scheduled for liver surgery at one of 10 medium-high volume Spanish HPB centers using an open or minimally invasive approach (robotic/laparoscopic/hybrid), regardless of diagnosis, ASA score <4, age ≥18, and who provide signed informed consent during the study period (September 2023 until the required sample size has been recruited). The participating researchers will be responsible for collecting the data and for reporting them to the study coordinators. Discussion This study will allow us to evaluate the VIBe scale for intraoperative bleeding in humans, with a view to its subsequent incorporation in daily clinical practice.

Abstract
BACKGROUND Textbook outcome is a composite measure used in surgery to define the ideal postoperative period and to assess the quality of care. The aim of this study was to analyze the incidence of textbook outcome and the factors independently associated with its achievement following surgical treatment of liver hydatid cysts. METHODS Retrospective cohort study of patients operated on for liver hydatid cysts between January 2006 and December 2021. Textbook outcome was achieved when all the following criteria were fulfilled: no mortality within 90 days, no major complications within 90 days, no hospital readmission within 90 days, and no prolonged hospital stay. Univariable and multivariable analyses were performed to identify factors associated with textbook outcome. RESULTS During the study period, 296 patients underwent surgery. Textbook outcome was recorded in 65.9% (195/296). Female gender (odds ratio 2.02; P = .010), noncomplicated cyst (odds ratio 3.97, P < .001), and radical surgery (odds ratio 2.26, P = .003) were the variables associated with a higher probability of achieving textbook outcome. CONCLUSION Textbook outcome may be a useful measure to assess the variations in surgical management between different centers, and to improve quality of care after liver hydatid cysts resection.

Abstract
BACKGROUND Cystic echinococcosis is a clinically complex chronic parasitic disease and a major socioeconomic problem in endemic areas. The safety of liver resection in elderly patients is often debated among medical professionals. We analyzed the postoperative morbidity and mortality rates of elderly patients who underwent surgery at our unit. METHODS We retrospectively evaluated patients with liver hydatid cysts which were surgically removed at our unit. Patients were divided into two groups: Group 1 (patients < 70 years), and Group 2 (patients ≥ 70 years). Propensity score matching (PSM) and comparative analyses between groups were performed. RESULTS The unmatched cohort consisted of 279 patients (Group 1: 244; Group 2: 35). After PSM, we compared the outcomes for 56 patients from Group 1 to 31 patients from Group 2. A higher rate of severe complications was observed in Group 2 (25.8% vs 5.36%, p = 0.014). No difference was found in the rates of infectious, cardiorespiratory, or hemorrhagic complications between both groups, and in the mortality rate either (0.00% vs 6.45%, p = 0.124). CONCLUSIONS Liver surgery in selected elderly patients is safe and practicable. The low postoperative morbidity rate in these patients is acceptable, albeit higher, due to their comorbidities.

Abstract
BACKGROUND Bleeding is an intraoperative and postoperative complication of liver surgery of concern, and yet evidence to support utility and reproducibility of bleeding scales for liver surgery is limited. We determined the reproducibility of the clinician-reported validated intraoperative bleeding severity scale and its clinical value of implementation in liver surgery. METHODS In this descriptive and observational multicenter study, we assessed the performance of liver surgeons instructed on the clinician-reported intraoperative bleeding severity scale using training videos that covered all 5 grades of bleeding severity. Surgeons were stratified according to years of surgical experience and number of surgeries performed per year based on a median split in low and high values. Intraobserver and interobserver agreement was assessed using Kendall's coefficient of concordance (Kendall's W). RESULTS Forty-seven surgeons from 10 hospitals in Spain participated in the study. The overall intraobserver concordance was 0.985, and the overall interobserver concordance was 0.929. For "high experience" surgeons, the intraobserver and interobserver agreement values were 0.990 and 0.941, respectively. For "low experience" surgeons, the intraobserver and interobserver agreement was 0.981 and 0.922, respectively. Regarding the annual number of surgeries, intraobserver and interobserver agreement values were 0.995 and 0.940, respectively, for surgeons performing >35 surgeries per year, with 0.979 and 0.923, respectively, for surgeons who perform ≤35 surgeries year. CONCLUSION The clinician-reported intraoperative bleeding severity scale shows high interobserver and intraobserver concordance, suggesting it is a useful tool for assessing severity of bleeding during liver surgery; years of surgical experience and number of annual procedures performed did not affect the applicability of the clinician-reported intraoperative bleeding severity scale.

Decreased Long-Term Severe Acute Respiratory Syndrome Coronavirus 2-Specific Humoral Immunity in Liver Transplantation Recipients 12 Months After Coronavirus Disease 2019. Liver Transpl 2022; 28:1039-1050.

Abstract
Long-term humoral immunity and its protective role in liver transplantation (LT) patients have not been elucidated. We performed a prospective multicenter study to assess the persistence of immunoglobulin G (IgG) antibodies in LT recipients 12 months after coronavirus disease 2019 (COVID-19). A total of 65 LT recipients were matched with 65 nontransplanted patients by a propensity score including variables with recognized impact on COVID-19. LT recipients showed a lower prevalence of anti-nucleocapsid (27.7% versus 49.2%; P = 0.02) and anti-spike IgG antibodies (88.2% versus 100.0%; P = 0.02) at 12 months. Lower index values of anti-nucleocapsid IgG antibodies were also observed in transplantation patients 1 year after COVID-19 (median, 0.49 [interquartile range, 0.15-1.40] versus 1.36 [interquartile range, 0.53-2.91]; P < 0.001). Vaccinated LT recipients showed higher antibody levels compared with unvaccinated patients (P < 0.001); antibody levels reached after vaccination were comparable to those observed in nontransplanted individuals (P = 0.70). In LT patients, a longer interval since transplantation (odds ratio, 1.10; 95% confidence interval, 1.01-1.20) was independently associated with persistence of anti-nucleocapsid IgG antibodies 1 year after infection. In conclusion, compared with nontransplanted patients, LT recipients show a lower long-term persistence of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies. However, SARS-CoV-2 vaccination after COVID-19 in LT patients achieves a significant increase in antibody levels, comparable to that of nontransplanted patients.

Abstract
INTRODUCTION It remains unclear whether liver resection is justified in patients with non-colorectal non-neuroendocrine liver metastases (NCNNLM). A single-center study was conducted to analyse overall survival (OS), disease-free survival (DFS), and potential prognostic factors in patients with different types of NCNNLM. METHOD A retrospective analysis of all patients who underwent liver resection of NCNNLM from January 2006 to July 2019 was performed. RESULTS A total of 62 patients were analyzed. 82.3% presented metachronous metastases and 74.2% were unilobar. The most frequent primary tumor site (PTS) were breast (24.2%), urinary tract (19.4%), melanoma (12.9%), and pancreas (9.7%). The most frequent primary tumor pathologies were breast carcinoma (24.2%), non-breast adenocarcinoma (21%), melanoma (12.9%) and sarcoma (12.9%). The most frequent surgical procedure performed was minor hepatectomy (72.6%). R0 resection was achieved in 79.5% of cases. The major complications' rate was 9.7% with a 90-day mortality rate of 1.6%. The 1, 3 and 5-year OS/DFS rate were 65%/28%, 45%/36% and 46%/28%, respectively. We identified the response to neoadjuvant therapy and PTS as possible prognostic factors for OS (P =0.06) and DFS (P =0.06) respectively. CONCLUSION Based on the results of our series, NCNNLM resection produces beneficial outcomes in terms of OS and DFS. PTS and the response to neoadjuvant therapy could be the main prognostic factors after resection.

Abstract
BACKGROUND Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients. METHODS Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020. Variables related to the primary tumor, demographics, clinical characteristics of metastasis, location in the pancreas, type of pancreatic resection performed and data on short and long-term evolution after pancreatic resection were collected. RESULTS The study included 116 patients. The mean time between nephrectomy and pancreatic metastases' resection was 87.35 months (ICR: 1.51-332.55). Distal pancreatectomy was the most performed technique employed (50 %). Postoperative morbidity was observed in 60.9 % of cases (Clavien-Dindo greater than IIIa in 14 %). The median follow-up time was 43 months (13-78). Overall survival (OS) rates at 1, 3, and 5 years were 96 %, 88 %, and 83 %, respectively. The disease-free survival (DFS) rate at 1, 3, and 5 years was 73 %, 49 %, and 35 %, respectively. Significant prognostic factors of relapse were a disease free interval of less than 10 years (2.05 [1.13-3.72], p 0.02) and a history of previous extrapancreatic metastasis (2.44 [1.22-4.86], p 0.01). CONCLUSIONS Pancreatic resection if metastatic RCC is found in the pancreas is warranted to achieve higher overall survival and disease-free survival, even if extrapancreatic metastases were previously removed. The existence of intrapancreatic multifocal compromise does not always warrant the performance of a total pancreatectomy in order to improve survival.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is the most common complication of pancreaticoduodenectomy (PD). Sometimes POPF is associated with biliary fistula (BF) or "mixed" fistula. The purpose of this study is to assess whether the severity of the fistulae, when present, is decreased with an external biliary stent in place. METHODS In this single-center study, we assessed patients who underwent elective PD from January 2014 to December 2017. Patients were divided into two groups: standard PD (ST-PD) vs. PD with external biliary stent (PD-BS). Demographic, preoperative, intraoperative, and postoperative variables were analyzed, including complications according to the Clavien-Dindo classification, and those specific to pancreatic surgeries, and mortality rates within 90 days of operation. RESULTS A total of 128 patients were included (65 in ST-PD group and 63 in PD-BS group). Postoperative complications occurred in 61.7% of patients (32.8%, Clavien-Dindo ≥ III) and were more common among patients in the PD-BS group (44.4% vs. 23.1%; p = 0.03). POPF was also more common among patients in the PD-BS group (39.7% vs. 18.5%; p = 0.008). No statistically significant differences were found for any other complications. CONCLUSION Based on the results of our study, placement of a transanastomotic external biliary stent does not reduce the rate of pancreatic or biliary fistulae, or their severity; in fact, POPF is more likely when biliary exteriorization is present.

Abstract
PURPOSE Echinococcosis, also known as hydatidosis, is a zoonosis that is endemic in many countries worldwide. Liver hydatid cysts have a wide variety of clinical manifestations, among which obstructive jaundice is one of the rarer forms. The aims of the study were to analyze the preoperative management of these patients and to record the kind of surgical treatment performed and the short- and long-term postoperative results. METHODS A retrospective two-center observational study of patients operated upon for liver hydatidosis with initial symptoms of obstructive jaundice. Preoperative characteristics, surgical data, and postoperative complications, including biliary fistula, were recorded. RESULTS Of 353 patients operated upon for liver hydatidosis, 44 were included in the study. Thirty-five patients (79.6%) were defined as CE2 or CE3 in the World Health Organization (WHO) classification. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) was performed in 25 patients (56.8%) and identified intrabiliary communication in 29. Radical surgery was carried out in 29 of the total sample (65.9%). Severe postoperative complications (Clavien-Dindo grade IIIA or higher) were recorded in 25% of patients. The factors associated with greater postoperative morbidity were age above 65 (HR 8.76 [95% CI 0.78-97.85]), cyst location (HR 4.77 [95% CI 0.93-24.42]), multiple cysts (HR 14.58 [95% CI 1.42-149.96]), and cyst size greater than 5 cm (HR 6.88 [95% CI 0.95-50]). CONCLUSION The presentation as obstructive jaundice causes greater postoperative morbidity. The main postoperative complication in these cases, despite radical surgery, is biliary fistula. In our series, routine preoperative ERCP did not show any benefit.

Melatonin Modulates the Antioxidant Defenses and the Expression of Proinflammatory Mediators in Pancreatic Stellate Cells Subjected to Hypoxia. Antioxidants (Basel) 2021; 10:antiox10040577. [PMID: 33918063 PMCID: PMC8070371 DOI: 10.3390/antiox10040577] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 04/01/2021] [Accepted: 04/05/2021] [Indexed: 12/11/2022] Open
Abstract
Pancreatic stellate cells (PSC) play a major role in the formation of fibrotic tissue in pancreatic tumors. On its side, melatonin is a putative therapeutic agent for pancreatic cancer and inflammation. In this work, the actions of melatonin on PSC subjected to hypoxia were evaluated. Reactive oxygen species (ROS) generation reduced (GSH) and oxidized (GSSG) levels of glutathione, and protein and lipid oxidation were analyzed. The phosphorylation of nuclear factor erythroid 2-related factor (Nrf2), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB), and the regulatory protein nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-alpha (IκBα) was studied. The expression of Nrf2-regulated antioxidant enzymes, superoxide dismutase (SOD) enzymes, cyclooxygenase 2 (COX-2), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were also studied. Total antioxidant capacity (TAC) was assayed. Finally, cell viability was studied. Under hypoxia and in the presence of melatonin generation of ROS was observed. No increases in the oxidation of proteins or lipids were detected. The phosphorylation of Nrf2 and the expression of the antioxidant enzymes catalytic subunit of glutamate-cysteine ligase, catalase, NAD(P)H-quinone oxidoreductase 1, heme oxygenase-1, SOD1, and of SOD2 were augmented. The TAC was increased. Protein kinase C was involved in the effects of melatonin. Melatonin decreased the GSH/GSSG ratio at the highest concentration tested. Cell viability dropped in the presence of melatonin. Finally, melatonin diminished the phosphorylation of NF-kB and the expression of COX-2, IL-6, and TNF-α. Our results indicate that melatonin, at pharmacological concentrations, modulates the red-ox state, viability, and the expression of proinflammatory mediators in PSC subjected to hypoxia.

Epidemiological pattern, incidence, and outcomes of COVID-19 in liver transplant patients. J Hepatol 2021; 74:148-155. [PMID: 32750442 PMCID: PMC7395653 DOI: 10.1016/j.jhep.2020.07.040] [Citation(s) in RCA: 234] [Impact Index Per Article: 78.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 07/23/2020] [Accepted: 07/27/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS The incidence and outcomes of coronavirus disease 2019 (COVID-19) in immunocompromised patients are a matter of debate. METHODS We performed a prospective nationwide study including a consecutive cohort of liver transplant patients with COVID-19 recruited during the Spanish outbreak from 28 February to 7 April, 2020. The primary outcome was severe COVID-19, defined as the need for mechanical ventilation, intensive care, and/or death. Age- and gender-standardised incidence and mortality ratios (SIR and SMR) were calculated using data from the Ministry of Health and the Spanish liver transplant registry. Independent predictors of severe COVID-19 among hospitalised patients were analysed using multivariate Cox regression. RESULTS A total of 111 liver transplant patients were diagnosed with COVID-19 (SIR = 191.2 [95% CI 190.3-192.2]). The epidemiological curve and geographic distribution overlapped widely between the liver transplant and general populations. After a median follow-up of 23 days, 96 patients (86.5%) were admitted to hospital and 22 patients (19.8%) required respiratory support. A total of 12 patients were admitted to the ICU (10.8%). The mortality rate was 18%, which was lower than in the matched general population (SMR = 95.5 [95% CI 94.2-96.8]). Overall, 35 patients (31.5%) met criteria of severe COVID-19. Baseline immunosuppression containing mycophenolate was an independent predictor of severe COVID-19 (relative risk = 3.94; 95% CI 1.59-9.74; p = 0.003), particularly at doses higher than 1,000 mg/day (p = 0.003). This deleterious effect was not observed with calcineurin inhibitors or everolimus and complete immunosuppression withdrawal showed no benefit. CONCLUSIONS Being chronically immunosuppressed, liver transplant patients have an increased risk of acquiring COVID-19 but their mortality rates are lower than the matched general population. Upon hospital admission, mycophenolate dose reduction or withdrawal could help in preventing severe COVID-19. However, complete immunosuppression withdrawal should be discouraged. LAY SUMMARY In liver transplant patients, chronic immunosuppression increases the risk of acquiring COVID-19 but it could reduce disease severity. Complete immunosuppression withdrawal may not be justified. However, mycophenolate withdrawal or temporary conversion to calcineurin inhibitors or everolimus until disease resolution could be beneficial in hospitalised patients.

Distal pancreatectomy with multivisceral resection: A retrospective multicenter study - Case series. Int J Surg 2020; 82:123-129. [PMID: 32860956 DOI: 10.1016/j.ijsu.2020.08.024] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 07/29/2020] [Accepted: 08/10/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Multivisceral resection (MVR) is sometimes necessary to achieve disease-free margins in cancer surgery. In certain patients with pancreatic tumors that invade neighboring organs these must be removed to perform an appropriate oncological surgery. In addition, there is an increasing need to perform resections of other organs like liver not directly invaded by the tumor but which require synchronous removal. The results of MVR in pancreatic surgery are controversial. MATERIAL AND METHODS A distal pancreatectomy retrospective multicenter observational study using prospectively compiled data carried out at seven HPB Units. The period study was January 2008 to December 2018. We excluded DP with celiac trunk resection. RESULTS 435 DP were performed. In 62 (14.25%) an extra organ was resected (82 organs). Comparison of the preoperative data of MVR and non-MVR patients showed that patients with MVR had lower BMI, higher ASA and larger tumor size. In the MVR group, the approach was mostly laparotomic and spleen preservation was performed only in 8% of the cases, Blood loss and the percentage of intraoperative transfusion were higher in MVR group. Major morbidity rates (Clavien > IIIa) and mortality (0.8vs.4.8%) were higher in the MVR group. Pancreatic fistula rates were practically the same in both groups. Mean hospital stay was twice as long in the MVR group and the readmission rate was higher in the MVR group. Histology study confirmed a much higher rate of malignant tumors in MVR group. CONCLUSIONS In order to obtain free margins or treat pathologies in several organs we think that DP + MVR is a feasible technique in selected patients; the results obtained are not as good as those of DP without MVR but are acceptable nonetheless.

Melatonin modulates red-ox state and decreases viability of rat pancreatic stellate cells. Sci Rep 2020; 10:6352. [PMID: 32286500 PMCID: PMC7156707 DOI: 10.1038/s41598-020-63433-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Accepted: 03/30/2020] [Indexed: 12/13/2022] Open
Abstract
In this work we have studied the effects of pharmacological concentrations of melatonin (1 µM-1 mM) on pancreatic stellate cells (PSC). Cell viability was analyzed by AlamarBlue test. Production of reactive oxygen species (ROS) was monitored following CM-H2DCFDA and MitoSOX Red-derived fluorescence. Total protein carbonyls and lipid peroxidation were analyzed by HPLC and spectrophotometric methods respectively. Mitochondrial membrane potential (ψm) was monitored by TMRM-derived fluorescence. Reduced (GSH) and oxidized (GSSG) levels of glutathione were determined by fluorescence techniques. Quantitative reverse transcription-polymerase chain reaction was employed to detect the expression of Nrf2-regulated antioxidant enzymes. Determination of SOD activity and total antioxidant capacity (TAC) were carried out by colorimetric methods, whereas expression of SOD was analyzed by Western blotting and RT-qPCR. The results show that melatonin decreased PSC viability in a concentration-dependent manner. Melatonin evoked a concentration-dependent increase in ROS production in the mitochondria and in the cytosol. Oxidation of proteins was detected in the presence of melatonin, whereas lipids oxidation was not observed. Depolarization of ψm was noted with 1 mM melatonin. A decrease in the GSH/GSSG ratio was observed, that depended on the concentration of melatonin used. A concentration-dependent increase in the expression of the antioxidant enzymes catalytic subunit of glutamate-cysteine ligase, catalase, NAD(P)H-quinone oxidoreductase 1 and heme oxygenase-1 was detected in cells incubated with melatonin. Finally, decreases in the expression and in the activity of superoxide dismutase were observed. We conclude that pharmacological concentrations melatonin modify the redox state of PSC, which might decrease cellular viability.

Abstract
BACKGROUND Renal cell carcinoma (RCC) can lead to secondary pancreatic tumors even years after nephrectomy was performed. Surgical resection in selected patients shows appropriate survival rates. METHODS A systematic review was performed following PRISMA guidelines. This review finished in May 2019 and included patients with resected pancreatic metastasis(es). The main purpose was to evaluate the results of surgical resection of pancreatic tumors secondary to kidney cancer. RESULTS After the screening process of articles, 21 were selected for the systematic review, which included 354 patients, whose disease-free interval (DFI) was 105.11 (0-361.56) months. Of these patients, 34.6% had additional metastases elsewhere at the time of the surgery, and 48.6% were symptomatic. Postoperative morbidity was 40.2%, The 5-year overall survival (OS) rate was 53.9% (26-75). CONCLUSION Pancreatic surgery for the resection of RCC metastasis(es) is considered safe and shows low morbidity and mortality rates among selected patients in medical institutions where this type of procedure is commonly performed.

Abstract
Different topical products have been tested in liver resection to get a control of bleeding. This study compares the effectiveness and complications between two haemostatic agents Tachosil versus Hemopatch. A cohort study including patients who underwent liver resection since November 2014 to April 2016 was conducted. The study was performed in a single institution. Demographic variables, intraoperative characteristics and postoperative complications were analysed. A total of 92 patients (50 in Tachosil group and 42 in Hemopatch group) were included. No differences were found in patients who required intraoperative (Tachosil 6 (12%) vs Hemopatch 2 (4.8%); p = 0.28) and postoperative (Tachosil 4 (8%) vs Hemopatch 3 (7.1%); p = 0.87) blood transfusion. There were no differences in length of hospital stay (Tachosil 7.02 ± 4.1 days vs Hemopatch 7.63 ± 9.1; p = 0.67). Overall postoperative complications were similar between both patches (Tachosil 21 (42%) vs Hemopatch 14 (33%); p = 0.48). No differences were found in specific complications, however Hemopatch showed a higher incidence of intraabdominal abscess 5 (11.9%) and vs 0 (0%) p = 0.01.In this study no differences have been found between Hemopatch and Tachosil in the effectiveness and overall postoperative complication after liver resection, although Hemopatch shows a higher incidence of intraabdominal abscess. Further studies are necessary to confirm these findings.

The Impact of Culturing the Organ Preservation Fluid on Solid Organ Transplantation: A Prospective Multicenter Cohort Study. Open Forum Infect Dis 2019; 6:ofz180.

Abstract
Background We analyzed the prevalence, etiology, and risk factors of culture-positive preservation fluid and their impact on the management of solid organ transplant recipients. Methods From July 2015 to March 2017, 622 episodes of adult solid organ transplants at 7 university hospitals in Spain were prospectively included in the study. Results The prevalence of culture-positive preservation fluid was 62.5% (389/622). Nevertheless, in only 25.2% (98/389) of the cases were the isolates considered "high risk" for pathogenicity. After applying a multivariate regression analysis, advanced donor age was the main associated factor for having culture-positive preservation fluid for high-risk microorganisms. Preemptive antibiotic therapy was given to 19.8% (77/389) of the cases. The incidence rate of preservation fluid-related infection was 1.3% (5 recipients); none of these patients had received preemptive therapy. Solid organ transplant (SOT) recipients with high-risk culture-positive preservation fluid receiving preemptive antibiotic therapy presented both a lower cumulative incidence of infection and a lower rate of acute rejection and graft loss compared with those who did not have high-risk culture-positive preservation fluid. After adjusting for age, sex, type of transplant, and prior graft rejection, preemptive antibiotic therapy remained a significant protective factor for 90-day infection. Conclusions The routine culture of preservation fluid may be considered a tool that provides information about the contamination of the transplanted organ. Preemptive therapy for SOT recipients with high-risk culture-positive preservation fluid may be useful to avoid preservation fluid-related infections and improve the outcomes of infection, graft loss, and graft rejection in transplant patients.

Abstract
Tumoral conditions in the round ligament of the liver are very uncommon and exhibit nonspecific manifestations, hence a high level of suspicion is necessary for their diagnosis. We report the case of a 47-year-old female patient who presented with abdominal pain for several months; imaging studies showed a lesion of indeterminate nature likely connected with the falciform ligament, and only intraoperative findings acknowledged the presence of an apparently benign tumor in the round ligament of the liver, which biopsy confirmed. Following the excision of the round ligament the patient had a favorable course. As this is a pathologically benign lesion we deem its surgical management both advisable and sufficient. However, because of its small prevalence and the scarcity of literature involving this condition, further studies would be needed to provide information on natural history, treatment, and long-term prognosis.

Regulation of cell death receptor S-nitrosylation and apoptotic signaling by Sorafenib in hepatoblastoma cells. Redox Biol 2015; 6:174-182.

Abstract
Nitric oxide (NO) plays a relevant role during cell death regulation in tumor cells. The overexpression of nitric oxide synthase type III (NOS-3) induces oxidative and nitrosative stress, p53 and cell death receptor expression and apoptosis in hepatoblastoma cells. S-nitrosylation of cell death receptor modulates apoptosis. Sorafenib is the unique recommended molecular-targeted drug for the treatment of patients with advanced hepatocellular carcinoma. The present study was addressed to elucidate the potential role of NO during Sorafenib-induced cell death in HepG2 cells. We determined the intra- and extracellular NO concentration, cell death receptor expression and their S-nitrosylation modifications, and apoptotic signaling in Sorafenib-treated HepG2 cells. The effect of NO donors on above parameters has also been determined. Sorafenib induced apoptosis in HepG2 cells. However, low concentration of the drug (10nM) increased cell death receptor expression, as well as caspase-8 and -9 activation, but without activation of downstream apoptotic markers. In contrast, Sorafenib (10 µM) reduced upstream apoptotic parameters but increased caspase-3 activation and DNA fragmentation in HepG2 cells. The shift of cell death signaling pathway was associated with a reduction of S-nitrosylation of cell death receptors in Sorafenib-treated cells. The administration of NO donors increased S-nitrosylation of cell death receptors and overall induction of cell death markers in control and Sorafenib-treated cells. In conclusion, Sorafenib induced alteration of cell death receptor S-nitrosylation status which may have a relevant repercussion on cell death signaling in hepatoblastoma cells.

Abstract
BACKGROUND Inflammatory pseudotumour is a rare entity, considered benign, and characterised by inflammatory cell mesenchymal proliferation. CLINICAL CASE The case is presented 70 year-old man with fever of unknown origin syndrome. He was diagnosed with liver abscesses (one segment IV, adjacent to gallbladder fundus and segment VI), who progressed slowly after antibiotic treatment. In the absence of a diagnosis, although fine needle puncture-aspiration and different imaging tests were performed, elective surgery was decided. The intra-operative histopathology reported the existence of an inflammatory pseudotumour. CONCLUSIONS Inflammatory pseudotumours are clinically classified into different types according to their aetiology, varying therapeutic management based on the same. It is very difficult to diagnose because of the absence of symptoms, blood disorders, or specific radiological findings. Definitive diagnosis often requires histopathological confirmation, in most cases by percutaneous liver puncture, but sometimes exploratory laparotomy or even performing a hepatectomy for confirmation is necessary. The natural history of inflammatory pseudotumour is its regression; thus conservative management may be used through regular checks until resolution, or can be treated with antibiotics, anti-inflammatories and even corticosteroids. Surgical resection is indicated for persistent unresolved systemic symptoms despite medical treatment, in those situations where growth is evident, with or without symptoms, when involving the hepatic hilum, and finally, in case where the possibility of malignancy cannot be ruled out.
