RESUMO

INTRODUCTION AND OBJECTIVES: De novo malignancies represent an important cause of death for liver transplant recipients. Our aim was to analyze predictors of extra-hepatic non-skin cancer (ESNSC) and the impact of ESNSC on the long-term outcome. PATIENTS: We examined data from patients transplanted between 2000 and 2005 and followed-up in five Italian transplant clinics with a retrospective observational cohort study. Cox Regression was performed to identify predictors of ESNSC. A 1:2 cohort sub-study was developed to analyze the impact of ESNSC on 10-year survival. RESULTS: We analyzed data from 367 subjects (median follow-up: 15 years). Patients with ESNSC (n = 47) more often developed post-LT diabetes mellitus (DM) (57.4% versus 35,9%, p = 0.004). At multivariate analysis, post-LT DM independently predicted ESNSC (HR 1.929, CI 1.029-3.616, p = 0.040). Recipients with ESNSC showed a lower 10-year survival than matched controls (46,8% versus 68,1%, p = 0.023). CONCLUSIONS: Post-LT DM seems to be a relevant risk factor for post-LT ESNSC. ESNSC could have a noteworthy impact on the long-term survival of LT recipients.

RESUMO

BACKGROUND: Laparoscopic liver resection (LLR) has gained increasing acceptance for surgical treatment of malignant and benign liver tumors. LLR for intrahepatic cholangiocarcinoma (ICC) is not commonly performed because of the concern for the frequent need for major hepatectomy, vascular-biliary reconstructions, and lymph node dissection (LND). The aim of this present meta-analysis is to compare surgical and oncological outcomes of laparoscopic (LLR) versus open liver resection (OLR) for ICC. MATERIALS AND METHODS: A systematic review was conducted using the PubMed, MEDLINE, and Cochrane library database of published studies comparing LLR and OLR up to October 2019. Two reviewers independently assessed the eligibility and quality of the studies. Dichotomous data were calculated by odds ratio (OR), and continuous data were calculated by mean difference (MD) with 95% confidence intervals (95% CI). RESULTS: Four retrospective observational studies describing 204 patients met the inclusion criteria. With respect to surgical outcomes, laparoscopic compared with open liver resection was associated with lower blood loss [MD - 173.86, (95% CI - 254.82, -92.91) p < 0.0001], less requirement of blood transfusion [OR 0.34, (95% CI 0.14, 0.82) p = 0.02], less need for Pringle maneuver [OR 0.17, (95% CI 0.07, 0.43) p = 0.0002], shorter hospital stay [MD - 3.77, (95% CI - 5.09, - 2.44; p < 0.0001], and less morbidity [OR 0.44, (95% CI 0.21, 0.94) p = 0.03]. With respect to oncological outcomes, the LLR group was prone to lower rates of lymphadenectomy [OR 0.12, (95% CI 0.06, 0.25) p < 0.0001], but surgical margins R0 and recurrence rate were not significantly different. CONCLUSION: Laparoscopic liver resection for ICC seems to achieve better surgical outcomes, providing short-term benefits without negatively affecting oncologic adequacy in terms of R0 resections and disease recurrence. However, a higher LND rate was observed in the open group. Due to the risk of bias and the statistical heterogeneity between the studies included in this review, further RCTs are needed to reach stronger scientific conclusions.

RESUMO

INTRODUCTION: Human echinococcosis is among the 17 neglected tropical diseases recognized by the World Health Organization. It is responsible for over $3 billion of health costs every year being endemic in large areas worldwide, and liver is affected in 70% of the cases. Surgery associated to medical treatment is the gold standard and robotic approach may be a valuable tool to achieve safe, parenchyma sparing resections. METHODS: We retrospectively analyzed the outcomes of patients that underwent robotic radical surgical treatment for hydatid liver disease, from prospectively maintained databases of three Italian centers. RESULTS: 15 patients were included in this study, median age 51 years (24-76). 1 right hepatectomy, 2 left lateral sectionectomies, 5 segmentectomies (including 1 caudatectomy), 3 wedge resections and 5 cyst-pericystectomies were performed. Median estimated blood loss was of 100 ml (50-550 ml), and median operative time including docking was 210 min (95-590 min), with no need for conversion to open. Median hospital stay was 4 days, with only one readmission for fever. Only one patient experienced recurrence in a different liver segment. CONCLUSIONS: In our experience, robotic approach for cystic echinococcosis of the liver proved to be a safe and effective strategy also in the so-called "difficult segments", with short post-operative stay and quick return to daily activities, along with the absence of surgical site recurrences. To the best of our knowledge, this is the largest report of robotic approach to hydatid liver disease.

RESUMO

BACKGROUND: Pancreatic neuroendocrine tumors (PanNETs) are relatively rare neoplasms with a low to mild malignant potential. They can be further divided into functioning and nonfunctioning, according to their secretive activity. Surgery is an optimal approach, but the classic open approach is challenging, with some patients having long hospitalization and potentially life-threatening complications. The robotic approach for PanNETs may represent an option to optimize their management. METHODS: We retrospectively reviewed our prospectively maintained databases from 2 high-volume Italian centers for pancreatic surgery. Demographics, pathological characteristics, perioperative outcome, and medium-term follow-up of patients who underwent robotic pancreatic enucleations were collected. RESULTS: Twelve patients with final diagnosis of PanNET were included. The mean age of the patients was 53.8 years (25-77). The median body mass index was 26 (24-29). Three lesions were functioning insulinomas, while the others were nonfunctioning tumors. No deaths occurred. Mild postoperative complications occurred, except for 1 grade B pancreatic fistula. The mean postoperative stay was 3.9 days (2-5). CONCLUSIONS: Our results confirm that robotic enucleation is a feasible and safe approach for the treatment of PanNETs, with short hospital stay and low incidence of morbidity.

RESUMO

BACKGROUND: Hepatocellular carcinoma has a growing incidence worldwide, and represents a leading cause of death in patients with cirrhosis. Nowadays, minimally invasive approaches are spreading in every field of surgery and in liver surgery as well. MATERIALS AND METHODS: We retrospectively reviewed demographics, clinical, and pathologic characteristics and short-term outcomes of patients who had undergone minimally invasive resections for hepatocellular carcinoma at our institution between June 2012 and May 2016. RESULTS: No significant differences in demographics and comorbidities were found between patients in the laparoscopic (n = 24) and robotic (n = 22) groups, except for the rates of cirrhotic patients (91.7% and 68.2%, respectively, P = 0.046). Perioperative data analysis showed that the operative time (mean, 211 and 318 min, respectively, P < 0.001) was the only parameter in favor of laparoscopy. Conversely, robotic-assisted resections were related to less Clavien I-II postoperative complications (22 cases versus 13 cases; P = 0.03). As regards resection margins, the two groups were similar with no statistically significant differences in rates of disease-free resection margins. CONCLUSIONS: A modern hepatobiliary center should offer both open and minimally invasive approaches to liver disease to provide the best care for each patient, according to the individual comorbidities, risk factors, and personal quality of life expectations. Our results show that the robotic approach is a reliable tool for accurate oncologic surgery, comparable to the laparoscopic approach. Robotic surgery also allows the surgeon to safely approach liver segments that are difficult to resect in laparoscopy, namely segments I-VII-VIII.

RESUMO

BACKGROUND: Pancreatic texture is one of the key predictors of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). Currently, the "gold standard" for assessment of pancreatic texture is surgeon's subjective evaluation through manual palpation. AIM: To evaluate a new "durometer" that is able to assess quantitatively the pancreatic stiffness by measuring its elastic module (i.e., the resistance offered by the pancreatic stump when elastically deformed expressed in mPa). METHODS: Measurements were obtained from the pancreatic remnant during 138 consecutive PDs performed at the Department of General and Pancreatic Surgery-The Pancreas Institute, University of Verona Hospital Trust. Values were correlated to clinical features and, in particular, with the senior surgeon's evaluation of pancreatic texture (hard/soft). Sixteen beating-heart donors were used as a control group to assess the stiffness of a non-pathologic pancreas. Univariate analysis was performed for the assessment of POPF predictors. RESULTS: Durometry allowed segregating between non-pathologic, soft and hard pancreas according to surgeon's evaluation (mean values 111 vs. 196 vs. 366 mPa, p < 0.01). There were no significant differences in stiffness with regard to histology, BMI, and neoadjuvant therapy. Larger tumors (>20 mm) and male sex were associated with greater stiffness on univariate analysis. Pancreatic texture, pancreatic duct size, BMI, prior neoadjuvant therapy, and histology were predictors of POPF. Patients who developed POPF showed a lesser stiffness (178 vs. 261 mPa, p = 0.05). CONCLUSION: Assessment of pancreatic stiffness using a durometer correlated with the surgeon's evaluation of pancreatic texture. Measurement of pancreatic parenchymal stiffness is reliable and correlates with the development of POPF.

RESUMO

BACKGROUND: We hypothesized that frailty acts as a measure of health outcomes in the context of LT. The aim of this study was to explore frailty index across LT, as a measure of morbidity and mortality. This was a retrospective observational study including all consecutive 47 HIV+patients who received LT in Modena, Italy from 2003 to June 2015. METHODS: frailty index (FI) was constructed from 30 health variables. It was used both as a continuous score and as a categorical variable, defining 'most frail' a FI > 0.45. FI change across transplant (deltaFI, ΔFI) was calculated as the difference between year 1 FI (FI-Y1) and pre-transplant FI (FI-t0). The outcomes measures were mortality and "otpimal LT" (defined as being alive without multi-morbidity). RESULTS: Median value of FI-t0 was 0.48 (IQR 0.42-0.52), FI-Y1 was 0.31 (IQR 0.26-0.41). At year five mortality rate was 45%, "optimal transplant" rate at year 1 was 38%. All the patients who died in the post-LT were most frail in the pre-LT. ΔFI was a predictor of mortality after correction for age and MELD (HR = 1.10, p = 0.006) and was inversely associated with optimal transplant after correction for age (HR = 1.04, p = 0.01). CONCLUSIONS: We validated FI as a valuable health measure in HIV transplant. In particular, we found a relevant correlation between FI strata at baseline and mortality and a statistically significant correlation between, ΔFI and survival rate.

RESUMO

BACKGROUND: According to the current literature, biliary lithiasis is a worldwide-diffused condition that affects almost 20% of the general population. The rate of common bile duct stones (CBDS) in patients with symptomatic cholelithiasis is estimated to be 10% to 33%, depending on patient's age. Compared to stones in the gallbladder, the natural history of secondary CBDS is still not completely understood. It is not clear whether an asymptomatic choledocholithiasis requires treatment or not. For many years, open cholecystectomy with choledochotomy and/or surgical sphincterotomy and cleaning of the bile duct were the gold standard to treat both pathologies. Development of both endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic surgery, together with improvements in diagnostic procedures, influenced new approaches to the management of CBDS in association with gallstones. DATA SOURCES: We decided to systematically review the literature in order to identify all the current therapeutic options for CBDS. A systematic literature search was performed independently by two authors using PubMed, EMBASE, Scopus and the Cochrane Library Central. RESULTS: The therapeutic approach nowadays varies greatly according to the availability of experience and expertise in each center, and includes open or laparoscopic common bile duct exploration, various combinations of laparoscopic cholecystectomy and ERCP and combined laparoendoscopic rendezvous. CONCLUSIONS: Although ERCP followed by laparoscopic cholecystectomy is currently preferred in the majority of hospitals worldwide, the optimal treatment for concomitant gallstones and CBDS is still under debate, and greatly varies among different centers.

RESUMO

Neurological complications (NCs) can frequently and significantly affect morbidity and mortality of liver transplant (LT) recipients. We analysed incidence, risk factors, outcome and impact of the immunosuppressive therapy on NC development after LT. We analysed 478 LT in 440 patients, and 93 (19.5%) were followed by NCs. The average LOS was longer in patients experiencing NCs. The 1-, 3- and 5-year graft survival and patient survival were similar in patients with or without a NC. Multivariate analysis showed the following as independent risk factors for NC: a MELD score ≥20 (OR = 1.934, CI = 1.186-3.153) and an immunosuppressive regimen based on calcineurin inhibitors (CNIs) (OR = 1.669, CI = 1.009-2.760). Among patients receiving an everolimus-based immunosuppression, the 7.1% developed NCs, vs. the 16.9% in those receiving a CNI (P = 0.039). There was a 1-, 3- and 5-year NC-free survival of 81.7%, 81.1% and 77.7% in patients receiving a CNI-based regimen and 95.1%, 93.6% and 92.7% in those not receiving a CNI-based regimen (P < 0.001). In patients undergoing a LT and presenting with nonmodifiable risk factors for developing NCs, an immunosuppressive regimen based on CNIs is likely to result in a higher rate of NCs compared to mTOR inhibitors.

RESUMO

BACKGROUND & AIMS: Salvage liver transplantation (SLT) is an attractive sequential strategy which combines liver resection (LR) for hepatocellular carcinoma (HCC), followed by liver transplant (LT) in the event of HCC recurrence or progressive liver deterioration. To compare the long-term results of SLT with primary liver transplant (PLT). METHODS: Between 2000 and 2011, 125 patients (72 transplantable) underwent LR and 226 underwent LT in our unit. The outcome of SLT was analysed in a two-step fashion: firstly, SLT (n = 28) was compared with PLT (n = 198), secondly an intention-to-treat analysis was performed on all transplantable HCC patients who underwent LR (LRT group = 72) compared to PLT (n = 198). RESULTS: The five-year overall survival (OS) was 65.4% vs. 49.2% (P = 0.63), and disease-free survival (DFS) was 89.7% vs. 80.6% (P = 0.31) for PLT and SLT respectively. Predictive factors for DFS after LT included HCC total diameter [hazard ratio (HR) 1.29 P = 0.003], alpha-foetoprotein (HR 1.002 P < 0.001) and number of HCC nodules (HR 1.317 P = 0.035), whereas viral hepatitis C positivity (HR 1.911 P = 0.03) and outside Up-to-seven criteria (HR 2.652 P < 0.001) were negative independent prediction factors of OS. Intention-to-treat analysis showed that OS at 5 years was improved in PLT vs. LRT (LRT n = 72 including SLT plus LR group) and was 69.4% vs. 42.2% (P < 0.004), with an additional increase in DFS (89.2% vs. 54.5% respectively P < 0.001). CONCLUSION: Salvage liver transplantation is a safe treatment strategy, as it does not impair long-term survival. At intention-to-treat analysis, PLT showed improved survival compared with LRT.

RESUMO

(1) Background: With ageing, the number of pancreaticoduodenectomies (PD) for benign or malignant disease is expected to increase in elderly patients. However, whether minimally invasive pancreaticoduodenectomy (MIPD) should be performed in the elderly is not clear yet and it is still debated. (2) Materials and Methods: A systematic review and meta-analysis was conducted including seven published articles comparing the technical and post-operative outcomes of MIPD in elderly versus younger patients up to December 2022. (3) Results: In total, 1378 patients were included in the meta-analysis. In term of overall and Clavien-Dindo I/II complication rates, post-operative pancreatic fistula (POPF) grade > A rates and biliary leakage, abdominal collection, post-operative bleeding and delayed gastric emptying rates, no differences emerged between the two groups. However, this study showed slightly higher intraoperative blood loss [MD 43.41, (95%CI 14.45, 72.38) p = 0.003], Clavien-Dindo ≥ III complication rates [OR 1.87, (95%CI 1.13, 3.11) p = 0.02] and mortality rates [OR 2.61, (95%CI 1.20, 5.68) p = 0.02] in the elderly compared with the younger group. Interestingly, as a minor endpoint, no differences in terms of the mean number of harvested lymphnode and of R0 resection rates were found. (4) Conclusion: MIPD seems to be relatively safe; however, there are slightly higher major morbidity, lung complication and mortality rates in elderly patients, who potentially represent the individuals that may benefit the most from the minimally invasive approach.

RESUMO

Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease, characterized by an intense desmoplastic reaction that compresses blood vessels and limits nutrient supplies. PDAC aggressiveness largely relies on its extraordinary capability to thrive and progress in a challenging tumor microenvironment. Dysregulation of the onco-suppressor miR-15a has been extensively documented in PDAC. Here, we identified the transcription factor Fos-related antigen-2 (Fra-2) as a miR-15a target mediating the adaptive mechanism of PDAC to nutrient deprivation. We report that the IGF1 signaling pathway was enhanced in nutrient deprived PDAC cells and that Fra-2 and IGF1R were significantly overexpressed in miR-15a downmodulated PDAC patients. Mechanistically, we discovered that miR-15a repressed IGF1R expression via Fra-2 targeting. In miR-15a-low context, IGF1R hyperactivated mTOR, modulated the autophagic flux and sustained PDAC growth in nutrient deprivation. In a genetic mouse model, Mir15aKO PDAC showed Fra-2 and Igf1r upregulation and mTOR activation in response to diet restriction. Consistently, nutrient restriction improved the efficacy of IGF1R inhibition in a Fra-2 dependent manner. Overall, our results point to a crucial role of Fra-2 in the cellular stress response due to nutrient restriction typical of pancreatic cancer and support IGF1R as a promising and vulnerable target in miR-15a downmodulated PDAC.

RESUMO

BACKGROUND: Pancreatic surgery has been associated with important postoperative morbidity, mortality and prolonged length of hospital stay. In pancreatic surgery, the effect of poor preoperative nutritional status and muscle wasting on postsurgery clinical outcomes still remains unclear and controversial. MATERIALS AND METHODS: A total of 103 consecutive patients with histologically proven carcinoma undergoing elective pancreatic surgery from June 2015 through to July 2020 were included and retrospectively studied. A multidimensional nutritional assessment was performed before elective surgery as required by the local clinical pathway. Clinical and nutritional data were collected in a medical database at diagnosis and after surgery. RESULTS: In the multivariable analysis, body mass index (OR 1.25, 95% CI 1.04-1.59, p = 0.039) and weight loss (OR 1.16, 95% CI 1.06-1.29, p = 0.004) were associated with Clavien score I-II; weight loss (OR 1.13, 95% CI 1.02-1.27, p = 0.027) affected postsurgery morbidity/mortality, and reduced muscle mass was identified as an independent, prognostic factor for postsurgery digestive hemorrhages (OR 0.10, 95% CI 0.01 0.72, p = 0.03) and Clavien score I-II (OR 7.43, 95% CI 1.53-44.88, p = 0.018). No association was identified between nutritional status parameters before surgery and length of hospital stay, 30 days reintervention, 30 days readmission, pancreatic fistula, biliary fistula, Clavien score III-IV, Clavien score V and delayed gastric emptying. CONCLUSIONS: An impaired nutritional status before pancreatic surgery affects many postoperative outcomes. Assessment of nutritional status should be part of routine preoperative procedures in order to achieve early and appropriate nutritional support in pancreatic cancer patients. Further studies are needed to better understand the effect of preoperative nutritional therapy on short-term clinical outcomes in patients undergoing pancreatic elective surgery.

RESUMO

HIV (human-immunodeficiency-virus) and HCV (hepatitis-C-virus) infections cause millions of deaths across the world every year. Since the introduction of effective therapies for HIV, in the middle of 1990s, and HCV, after 2013, those two untreatable infections became completely controlled. Donor safety is the main goal in living donor liver transplantation (LDLT). An accurate predonation screening is mandatory for excluding risk factors related with any increase of donors' short-term and long-term morbidity. We present the first LDLT from a donor with both HIV and HCV previous infections. Donor and recipient did not experience any complication. Individuals with well controlled HIV/HCV infections and without any risk factors may be suitable for donation of a part of their healthy liver. Abstract video, http://links.lww.com/QAD/C833.

RESUMO

Background: Pancreatic trauma is an uncommon injury that occurs usually in a young population and is frequently overlooked and not readily appreciated on initial examination. Nowadays, the diagnosis and management of pancreatic trauma are still controversial, and there is no gold standard for the treatment. The aim of this study is to describe our experience in the management of blunt pancreatic trauma with a laparoscopic approach and review the literature on laparoscopic management of pancreatic trauma. Methods: A systematic literature review was performed, and 40 cases were reported and analysed; 10 cases were excluded because the complete data were not retrievable. We also reported our experience with the case of an 18-year-old male diagnosed with a deep laceration of the pancreas between body and tail, involving the main pancreatic duct, and with a concomitant hematoma. The patient underwent exploratory laparoscopy with abdominal toilet, necrosectomy, and suture of main pancreatic duct; the total blood loss was less than 200 ml, and the total operative time was 180 minutes. The patient recovered uneventfully and was discharged on the 6th postoperative day. Results: 30 patients with pancreatic trauma, 10 adults and 20 pediatrics (mean age 28.2 years and 10.5 years), underwent a total laparoscopic approach: 2 distal pancreatic-splenectomy, 22 spleen-preserving distal pancreatectomy, and 6 laparoscopic drainage. The mean operative time for the adult and pediatric populations was 160.6 and 214.5 minutes, the mean estimated blood loss was 400 ml and 75 ml, and the mean hospital stay was 14.9 and 9 days, respectively. Conclusion: Laparoscopic management for pancreatic trauma can be considered feasible and safe when performed by an experienced laparoscopic pancreatic team, and in such a setting, it can be considered a viable alternative to open surgery, offering the well-known benefits of minimally invasive surgery.

RESUMO

Incisional hernias (IHs) are common complications after liver transplantation (LT) with a reported incidence of 1.7% to 34.3%. The purpose of this retrospective study was to evaluate the risk factors for IH development after LT with a focus on the role of immunosuppressive therapy during the first month after LT. We analyzed 373 patients who underwent LT and divided them into 2 groups according to their postoperative course: an IH group (121 patients or 32.4%) and a no-IH group (252 patients or 67.6%). A univariate analysis demonstrated that the following were risk factors related to IH development: male sex (P = 0.03), a body mass index ≥ 29 kg/m(2) (P = 0.005), LT after 2004 (P = 0.02), a Model for End-Stage Liver Disease (MELD) score ≥ 22 (P = 0.01), and hepatitis B virus infection (P = 0.01). The highest incidence of IHs was found in patients treated with mammalian target of rapamycin (mTOR) inhibitors (54.5%, P = 0.004). A multivariate analysis revealed male sex (P = 0.03), a pretransplant MELD score ≥ 22 (P = 0.04), and the use of mTOR inhibitors (P = 0.001) to be independent risk factors for IHs after LT. In conclusion, immunosuppressive therapy with mTOR inhibitors is an important independent risk factor for IH development after LT. To reduce the incidence of IHs, mTOR inhibitors should be avoided until the fourth month after LT unless their use is deemed to be strictly necessary.

RESUMO

This study reports one case of primary inferior vena cava (IVC) leiomyosarcoma. A 67-year-old woman was referred to the authors' clinic for evaluation. She presented complaining of epigastric and right upper abdominal quadrant pain. Contrast-enhanced abdominal computed tomography scan revealed a 5.2 × 6.4 cm heterogeneously enhancing mass involving the anteromedial aspect of the IVC, below the renal vein (segment I), deforming the duodenum. There was a partial intraluminal extension in the IVC. Laparotomic resection was performed, with total en bloc excision of the lower IVC tumor. The caval continuity was restored with concomitant interposition of a banked depopulated vena cava homograft. Histological findings showed leiomyosarcoma originating from IVC. The postoperative course was uneventful: Neither recurrence nor metastasis was evident at 4 years postsurgery.

RESUMO

(1) Background: Primary liver transplantation (PLT) for HCC represents the ideal treatment. However, since organ shortage increases the risk of drop-out from the waiting list for tumor progression, a new surgical strategy has been developed: Salvage Liver Transplantation (SLT) can be offered as an additional curative strategy for HCC recurrence after liver resection. The aim of this updated meta-analysis is to compare surgical and long-term outcomes of SLT versus PLT for HCC. (2) Materials and Methods: A systematic review and meta-analysis was conducted using the published papers comparing SLT and PLT up to January 2022. (3) Results: 25 studies describing 11,275 patients met the inclusion criteria. The meta-analysis revealed no statistical difference in intraoperative blood loss, overall vascular complications, retransplantation rate, and hospital stay in the SLT group compared with the PLT group. However, the SLT group showed a slightly significant lower 5-year OS rate and 5-year disease-free survival rate. (4) Conclusion: meta-analysis advocates the relative safety and feasibility of both Salvage LT and Primary LT strategies. Specifically, SLT seems to have comparable surgical outcomes but slightly poorer long-term survival than PLT.
