    The impact of multivisceral liver resection on short- and long-term outcomes of patients with colorectal liver metastasis: A systematic review and meta-analysis
    (2022) SILVEIRA JUNIOR, Sergio; TUSTUMI, Francisco; MAGALHAES, Daniel de Paiva; JEISMANN, Vagner Birk; FONSECA, Gilton Marques; KRUGER, Jaime Arthur Pirola; COELHO, Fabricio Ferreira; HERMAN, Paulo
    The impact of Multivisceral Liver Resection (MLR) on the outcome of patients with Colorectal Liver Metastasis (CRLM) is unclear. The present systematic review aimed to compare patients with CRLM who underwent MLR versus standard hepatectomy regarding short-and long-term outcomes. MLR is a feasible procedure but has a higher risk of major complications. MLR did not negatively affect long-term survival, suggesting that an extended resection is an option for potentially curative treatment for selected patients with CRLM.

    Preoperative inflammatory markers as prognostic predictors after hepatocellular carcinoma resection: data from a western referral center
    (2022) SILVA, Joao Paulo Maciel; COELHO, Fabricio Ferreira; CASSENOTE, Alex Jones Flores; JEISMANN, Vagner Birk; FONSECA, Gilton Marques; KRUGER, Jaime Arthur Pirola; MEIRA JUNIOR, Jose Donizeti de; NAHAS, Sergio Carlos; HERMAN, Paulo
    Background Recent studies from eastern centers have demonstrate an association between inflammatory response and long-term outcomes after hepatocellular carcinoma (HCC) resection. However, the prognostic impact of inflammatory markers in western patients, with distinct tumor and epidemiologic features, is still unknown. Aim To evaluate the prognostic impact of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), as well as their impact according to tumor size (< 5 cm, 5-10 cm, > 10 cm) in patients undergoing HCC resection with curative intent. Methods Optimal cut-off values for NLR, PLR, and MLR were determined by plotting the receiver operator curves. Overall survival (OS) and disease-free survival (DFS) curves were calculated using the Kaplan-Meier method and compared using the log-rank test. The Cox method was used to identify independent predictors of OS and DFS. Results In total, 161 consecutive adult patients were included. A high NLR (> 1.715) was associated with worse OS (P = 0.018). High NLR (> 2.475; P = 0.047) and PLR (> 100.25; P = 0.028) were predictors of short DFS. In HCC < 5 cm, MLR (> 1.715) was associated with worse OS (P = 0.047). In the multivariate analysis, high PLR was an independent predictor of worse DFS [hazard ratio (HR) 3.029; 95%CI 1.499-6.121; P = 0.002]. Conclusion Inflammatory markers are useful tools to predict long-term outcomes after liver resection in western patients, high NLR was able to stratify subgroups of patients with short OS and DFS, an increased PLR was an independent predictor of short DFS, while high MLR was associated with short OS in patients with early HCC.

    Two decades of liver resection with a multidisciplinary approach in a single institution: What has changed? Analysis of 1409 cases
    (2022) HERMAN, Paulo; FONSECA, Gilton Marques; COELHO, Fabricio Ferreira; KRUGER, Jaime Arthur Pirola; MAKDISSI, Fabio Ferrari; JEISMANN, Vagner Birk; CARRILHO, Flair Jose; D'ALBUQUERQUE, Luiz Augusto Carneiro; NAHAS, Sergio Carlos
    Objectives: To evaluate results of patients undergoing liver resection in a single center over the past two decades with a particular look at Colorectal Liver Metastasis (CRLM) and Hepatocellular Carcinoma (HCC). Method: Patients were divided into two eras, from 2000 to 2010 (Era 1) and 2011 to 2020 (Era 2). The most frequent diagnosis was CRLM and HCC, with 738 (52.4%) and 227 (16.1%) cases respectively. An evaluation of all liver resection cases and a subgroup analysis of both CRLM and HCC were performed. Preoperative and per operative variables and long-term outcomes were evaluated. Results: 1409 liver resections were performed. In Era 2 the authors observed higher BMI, more: minimally invasive surgeries, Pringle maneuvers, and minor liver resections; and less transfusion, less ICU necessity, and shorter length of hospital stay. Severe complications were observed in 14.7% of patients, and 90-day mortality was 4.2%. Morbidity and mortality between eras were not different. From 738 CRLM resections, in Era 2 there were significantly more patients submitted to neoadjuvant chemotherapy, bilateral metastases, and smaller sizes with significantly less transfusion, the necessity of ICU, and shorter length of hospital stay. More pedicle clamping, minimally invasive surgeries, and minor resections were also observed. From 227 HCC resections, in Era 2 significantly more minimally invasive surgeries, fewer transfusions, less necessity of ICU, and shorter length of hospital stay were observed. OS was not different between eras for CRLM and HCC. Conclusions: Surgical resection in a multidisciplinary environment remains the cornerstone for the curative treatment of primary and metastatic liver tumors.

    A Combined ""Hanging Liver Maneuver"" and ""Intrahepatic Extra-Glissonian Approach"" for Anatomical Right Hepatectomy: Technique Standardization, Results, and Correlation With Portal Pedicle Anatomy
    (2021) MAKDISSI, Fabio Ferrari; MATTOS, Bruno Vinicius Hortences de; KRUGER, Jaime Arthur Pirola; JEISMANN, Vagner Birk; COELHO, Fabricio Ferreira; HERMAN, Paulo
    Background: The hanging liver maneuver and intrahepatic extra-Glissonian approach are distinct modalities to facilitate safe anatomical liver resections. This study reports a standardized combination of these techniques focusing on safety, results and correlation with portal pedicle anatomy in oncological patients. Method: Combined hanging liver maneuver and intrahepatic extra-Glissonian approach for anatomic right hepatectomy was described stepwise. Portal pedicle anatomy was correlated with the Glissonian approach failure and complications. Clinical characteristics of patients, perioperative outcomes, short and long-term survival rates were analyzed. Results: Thirty colorectal liver metastases patients submitted to the combined approach were evaluated. Anatomical variations of the right portal pedicle were present in 26.6%. Hanging liver maneuver was feasible in 100%, and Glissonian approach in 96.7% despite portal pedicle variations. Mean operative time was 326 min. Mean blood loss was 507 ml. Mean hospital stay was 8 days. There was no 90-day operative mortality and no significant morbidity. Oncological surgical margins were free. Overall and disease-free 5-year survival were 59 and 37%. Conclusion: Regardless of frequent anatomical variations of the right portal pedicle, the hanging liver maneuver, and intrahepatic extra-Glissonian approach can be combined, being useful for anatomical right hepatectomies in a safe and reproducible way in most patients.

    Feasibility of Right Upper Transversal Hepatectomy in the Absence of an Inferior Right Hepatic Vein: New Insights regarding This Complex Procedure
    (2021) MAKDISSI, Fabio Ferrari; KRUGER, Jaime Arthur Pirola; JEISMANN, Vagner Birk; HERMAN, Paulo
    Background. Right upper transversal hepatectomy (RUTH) is defined as the removal of liver segments 7, 8, and 4A with ligature of the right and middle hepatic veins and is considered one of the most complex techniques of parenchymal-sparing hepatectomies. This procedure can be performed, without venous reconstruction, if collateral veins are present communicating within remnant liver segments to a large inferior right hepatic vein and/or to the left hepatic vein. This venous network could maintain outflow from the inferior right segments (S5, S6) to the left liver when a RUTH is performed, even in the absence of an inferior right hepatic vein. The aim of this study is to present our experience with RUTH without venous reconstruction in patients with and without the presence of an inferior right hepatic vein (IRHV). Methods. Patients submitted to RUTH for treatment of liver metastases were selected from our database. The presence of an IRHV, clinical and surgical characteristics of the patients, immediate outcomes, viability of liver segments 5 and 6, and long-term survival were analyzed. Results. RUTH was successfully performed in four patients. In two patients, IRHV was not present, but intrahepatic communicating veins between proximal right and middle hepatic veins and left hepatic vein were present. No venous reconstructions were performed. Mild congestion of the inferior right segments occurred in the patients where there was no IRHV but no immediate, early, or late complications were observed. Conclusions. RUTH is feasible and can be performed even in the absence of an IRHV, without venous reconstruction. Some degree of congestion of the right inferior liver segments might occur when an IRHV is absent, yet this is not clinically significant when communicating veins are present. Maximum parenchyma preservation might prevent postoperative liver failure and allow repeated resections in case of hepatic recurrence.

    LAPAROSCOPIC LIVER RESECTION FOR BENIGN TUMORS: THE CURRENT POSITION
    (2021) HERMAN, Paulo; FONSECA, Gilton Marques; KRUGER, Jaime Arthur Pirola; JEISMANN, Vagner Birk; COELHO, Fabricio Ferreira
    BACKGROUND: The main indications of the use of laparoscopic liver surgery (LLS), in the early days, were benign liver lesions. As LLS became more popular, indications for malignant diseases outnumbered those for benign ones. This study aims to rule out the indications and results of LLS for the treatment of benign liver tumors. METHODS: Out of 445 LLS performed in a single center, 100 (22.4%) were for benign tumors. The authors discuss the indications for resection and present their perioperative results. RESULTS: In total, 100 patients with benign tumors were evaluated. Specifically, these were as follows: 66 cases of hepatocellular adenomas; 14 cases of biliary mucinous neoplasm; 13 cases of focal nodular hyperplasia; 4 cases of angiomyolipomas; and 3 cases of hemangiomas with a mean size of 7.6 cm (ranging from 3.1 to 19.6 cm). The total morbidity rate was 19%, with 9% classified as Clavien-Dindo grades 3 or 4. No mortality was observed. CONCLUSION: LLS for benign liver tumors is safe and presents excellent results. However, indications for resection are increasingly restricted and should not be performed just because it is a minimally invasive procedure.

    Mucinous cystic neoplasm of the liver with biliary communication: case report and surgical therapeutic option
    (2020) FERREIRA, Raphaella; ABREU, Phillipe; JEISMANN, Vagner Birk; SEGATELLI, Vanderlei; COELHO, Fabricio Ferreira; DAVID, Andre Ibrahim
    Background Mucinous cyst neoplasm of the liver (MCN-L) comprise less than 5% of all cystic liver lesions and is characterized by the presence of ovarian stroma and absence of bile duct communication. Case presentation Here, we discuss a 45-year-old woman who presented with symptomatic liver mass. Diagnostic workup detected a 4.2 x 3.6 cm septate cyst located in segments I, V, and VIII of the liver in communication with the right hepatic duct. An open right liver resection with total bile duct excision and hilar lymphadenectomy was performed. Pathology revealed a multiloculated cyst with lined mucinous epithelium and ovarian-like stroma, consistent with low-grade MCN-L. Conclusions This case shows that unusual location and bile duct communication can be present in MCN-L.
