- Extended right hepatectomy with caudate lobe resection using the hilar ""en bloc"" resection technique with a modified hanging maneuver(2016) PERINI, Marcos V.; COELHO, Fabricio F.; KRUGER, Jaime A.; ROCHA, Flavio G.; HERMAN, PauloThe hanging liver maneuver is a useful technique to guide the transection of liver parenchyma by lifting a tape passed between the anterior surface of the inferior vena cava and the liver. Modified hanging liver maneuvers have been described in different types of liver resection. Surgical resection of hilar cholangiocarcinoma can involve the portal vein and the caudate lobe for margin clearance. However, hilar dissection and resection of the caudate lobe can be a challenging during the hanging maneuver once the tape is positioned. Herein, we describe a modified hanging liver maneuver for a hilar en bloc extended right hepatectomy with portal vein resection for the treatment of hilar cholangiocarcinoma including the caudate lobe.

- Long-term oncological outcomes for HALS/Hybrid vs pure laparoscopic approach in colorectal liver metastases: a propensity score matched analysis(2023) LOPEZ-LOPEZ, Victor; KRURGER, Jaime Arthur Pirola; KUEMMERLI, Christopher; TOHME, Samer; GOMEZ-GAVARA, Concepcion; INIESTA, Maria; LOPEZ-CONESA, Asuncion; DOGEAS, Epameinondas; DALMAU, Mar; BRUSADIN, Roberto; SANCHEZ-ESQUER, Ignacio; GELLER, David A.; HERMAN, Paulo; ROBLES-CAMPOS, RicardoBackgroundStudies comparing hand-assisted laparoscopic (HALS)/Hybrid and pure laparoscopic (PLS) resection for colorectal cancer liver metastasis have focused on short-term results, while long-term oncological outcomes remain understudied.MethodsWe established a multi-institutional retrospective cohort study from four centers with experience in minimally invasive surgery between 2004 and 2020. Primary endpoints were overall survival (OS) and disease-free survival (DFS). Other endpoints analyzed were intraoperative and postoperative outcomes. Propensity score matching (PSM) was used to minimize baseline differences.ResultsA total of 219 HALS/Hybrid (57.8%) and 160 PLS (42.2%) patients were included. After PSM, 155 patients remained in each group. Operative time (182 vs. 248 min, p = 0.012), use of intraoperative ablation (12.3 vs. 4.5%, p = 0.024), positive resection margin (4.5 vs 13.2%, p = 0.012), and pringle time (21 vs. 37 min, p = 0.001) were higher in PLS group. DFS at 1, 3, 5, and 7 years in HALS/Hybrid and PLS groups were 65.4%, 39.3%, 37.5%, and 36.3% vs. 64.9%, 38.0%, 33.1%, and 33.1%, respectively (p = 0.84). OS at 1, 3, 5, and 7 years in HALS/Hybrid and PLS groups were 94.5%, 71.4%, 54.3%, and 46.0% vs. 96.0%, 68.5%, 51.2%, and 41.2%, respectively (p = 0.73).ConclusionOur study suggests no differences in long-term oncologic outcomes between the two techniques. We discovered that longer total operative, pringle time, higher rates of intraoperative ablation, and positive resection margins were associated with PLS. These differences in favor of HALS/Hybrid could be due to a shorter learning curve and a greater ability to control hemorrhage.
- Combined liver and multivisceral resections: A comparative analysis of short and long-term outcomes(2020) JUNIOR, Sergio S.; COELHO, Fabricio F.; TUSTUMI, Francisco; CASSENOTE, Alex J. F.; JEISMANN, Vagner B.; FONSECA, Gilton M.; KRUGER, Jaime A. P.; ERNANI, Lucas; CECCONELLO, Ivan; HERMAN, PauloBackground En bloc liver and adjacent organs resections are technically demanding procedures. Few case series and nonmatched comparative studies reported the outcomes of multivisceral liver resections (MLRs). Objectives To compare the short and long-term outcomes of patients submitted MLRs with those submitted to isolated hepatectomies. Methods From a prospective database, a case-matched 1:2 study was performed comparing MLRs and isolated hepatectomy. Additionally, a risk analysis was performed to evaluate the association between MLRs and perioperative morbidity, mortality, and long-term survival. Results Fifty-three MLRs were compared with 106 matched controls. Patients undergoing MLRs had longer operative time (430 [320-525] vs 360 [270-440] minutes,P = .005); higher estimated blood loss (600 [400-800] vs 400 [100-600] mL;P = .011); longer hospital stay (8 [6-14] vs 7 [5-9] days;P = .003); and higher postoperative mortality (9.4% vs 1.9%,P = .042). Number of resected organs was not an independent prognostic factor for perioperative major complications (odds ratio [OR], 1 organ = 1.8 [0.54-6.05]; OR >= 2, organs = 4.0 [0.35-13.84]) or perioperative mortality (OR, 1, organ = 5.2 [0.91-29.51]; OR >= 2, organs = 6.5 [0.52-79.60]). No differences in overall (P = .771) and disease-free survival (P = .28) were observed. Conclusion MLRs are feasible with acceptable morbidity but relatively high perioperative mortality. MLRs did not negatively affect long-term outcomes.
- Prognostic significance of poorly differentiated clusters and tumor budding in colorectal liver metastases(2018) FONSECA, Gilton M.; MELLO, Evandro S. de; FARAJ, Sheila F.; KRUGER, Jaime A. P.; COELHO, Fabricio F.; JEISMANN, Vagner B.; LUPINACCI, Renato M.; CECCONELLO, Ivan; ALVES, Venancio A. F.; PAWLIK, Timothy M.; HERMAN, PauloBackgroundHistomorphological features have been described as prognostic factors after resection of colorectal liver metastases (CLM). The objectives of this study were to assess the prognostic significance of tumor budding (TB) and poorly differentiated clusters (PDC) among CLM, and their association with other prognostic factors. MethodsWe evaluated 229 patients who underwent a first resection of CLM. Slides stained by HE were assessed for TB, PDC, tumor border pattern, peritumoral pseudocapsule, peritumoral, and intratumoral inflammatory infiltrate. Lymphatic and portal invasion were evaluated through D2-40 and CD34 antibody. ResultsFactors independently associated with poor overall survival were nodules>4 (P=0.002), presence of PDC G3 (P=0.007), portal invasion (P=0.005), and absence of tumor pseudocapsule (P=0.006). Factors independently associated with disease-free survival included number of nodules>4 (P<0.001), presence of PDC G3 (P=0.005), infiltrative border (P=0.031), portal invasion (P=0.006), and absent/mild peritumoral inflammatory infiltrate (P=0.002). PDC and TB were also associated with histological factors, as portal invasion (TB), peritumoral inflammatory infiltration (PDC), infiltrative border, and absence of tumor pseudocapsule (TB and PDC). ConclusionsThis is the first study demonstrating PDC as a prognostic factor in CLM. TB was also a prognostic factor, but it was not an independent predictor of survival.
- Liver resection for hepatolithiasis: A multicenter experience in Latin America(2023) GARCIA, Daniel; MARINO, Carlo; COELHO, Fabricio Ferreira; REBOLLEDO, Patricia; ACHURRA, Pablo; FONSECA, Gilton Marques; KRUGER, Jaime A. P.; VINUELA, Eduardo; BRICENO, Eduardo; D'ALBUQUERQUE, Luiz Carneiro; JARUFE, Nicolas; MARTINEZ, Jorge A.; HERMAN, Paulo; DIB, Martin J.Background: Hepatolithiasis is a prevalent disease in Asia but rare in Western countries. An increasing number of cases have been reported in Latin America. Liver resection has been proposed as a definitive treatment for complete stone clearance. The aim of this study was to evaluate the postoperative out-comes of liver resection for the treatment of hepatolithiasis in 2 large hepatobiliary reference centers from South America.Methods: We conducted a retrospective descriptive analysis from patients with hepatolithiasis who underwent liver resection between November 1986 and December 2018, in 2 Latin-American centers in Chile and Brazil.Results: One hundred forty-nine patients underwent liver resection for hepatolithiasis (72 in Chile, 77 in Brazil). The mean age was 49 years and most patients were female (62.4%). Hepatolithiasis was localized in the left lobe (61.7%), right lobe (24.2%), and bilateral lobe (14.1%). Bilateral lithiasis was associated with higher incidence of preoperative and postoperative cholangitis (81% vs 46.9% and 28.6% vs 6.1%) and need for hepaticojejunostomy (52.4%). In total, 38.9% of patients underwent major hepatectomy and 14.1% were laparoscopic. The postoperative stone clearance was 100%. The 30-day morbidity and mortality rates were 30.9% and 0.7%, respectively. Cholangiocarcinoma was seen in 2 specimens, and no post-operative malignancy were seen after a median follow-up of 38 months. Fourteen patients (9.4%) had intrahepatic stones recurrence.Conclusions: Liver resection is an effective and definitive treatment for patients with hepatolithiasis. Bilateral hepatolithiasis was associated with perioperative cholangitis, the need for hepaticojejunostomy, and recurrent disease. Resection presents a high rate of biliary tree stone clearance and excellent long-term results, with low recurrence rates and low risk of malignancy.(c) 2022 Elsevier Inc. All rights reserved.
- Evolution in the surgical management of colorectal liver metastases: Propensity score matching analysis (PSM) on the impact of specialized multidisciplinary care across two institutional eras(2018) KRUGER, Jaime A. P.; FONSECA, Gilton M.; MAKDISSI, Fabio F.; JEISMANN, Vagner B.; COELHO, Fabricio F.; HERMAN, PauloBackground and Objectives: Liver metastases are indicators of advanced disease in patients with colorectal cancer. Liver resection offers the best possibility of long-term survival. Surgical strategies have evolved in complexity in order to offer resection to a greater number of patients, requiring specialized multidisciplinary care. The current paper focused on analyzing outcomes of patients treated after the development of a dedicated cancer center in our institution. Methods: Patients operated on for CLM from our databank were paired through propensity score matching (PSM), and the initial experience of surgery for CLM was compared with the treatment performed after specialized multidisciplinary management. The demographic, oncological, and surgical features were analyzed between groups. Results: Overall, 355 hepatectomies were performed in 336 patients. Patients operated on during the second era of had greater use of preoperative chemotherapy (P<0.001) as well as exposure to more effective oxaliplatin-based regimens (P<0.001). Surgical management also changed, with minor (P=0.002) and non-anatomic (P=0.006) resections preferred over major operations. We also noted an increased number of minimally invasive resections (P<0.001). Conclusion: Treatment in a multidisciplinary cancer center led to changes in oncological and surgical management. Perioperative chemotherapy was frequently employed, and surgeons adopted a conservative approach to liver parenchyma.
- Platelet-albumin (PAL) score as a predictor of perioperative outcomes and survival in patients with hepatocellular carcinoma undergoing liver resection in a Western center(2022) MEIRA JUNIOR, Jose Donizeti de; FONSECA, Gilton Marques; CARVALHO NETO, Francisco Nolasco de; JEISMANN, Vagner Birk; KRUGER, Jaime Arthur Pirola; SILVA, Joao Paulo Maciel; COELHO, Fabricio Ferreira; HERMAN, PauloBackground and objectives: Preoperative selection of patients with hepatocellular carcinoma (HCC) who will benefit from resection is highly advisable. The Platelet-Albumin (PAL) score was developed as a predictor of survival and morbidity following HCC resection. However, this has never been tested in western populations.& nbsp;Methods: The impact of PAL score on perioperative outcomes and survival was evaluated and compared to Child Pugh, Model for End-Stage Liver Disease (MELD), and albumin-bilirubin (ALBI) scores in patients who underwent HCC resection.& nbsp;Results: A total of 182 patients were included. Postoperative morbidity was higher in patients with PAL grade II III (P = 0.039), ALBI grade II-III (P = 0.028), and MELD > 10 (P = 0.042). Post-hepatectomy liver failure (PHLF) occurred in 36 patients (19.8%) and was significantly higher in the PAL II-III and ALBI score II-III subgroup (P = 0.001). The PAL II-III group was the only one associated with higher perioperative mortality (OR 3.3, P = 0.036). The PAL score was an independent prognostic factor for overall survival in multivariate analysis (P = 0.018) and was the only one with the areas under the curve in ROC analysis significantly different for morbidity, PHLF, and mortality.& nbsp;Conclusions: The PAL score predicts postoperative complications, mortality, PHLF, and survival following liver resection for HCC in western patients.
- Are Hybrid Liver Resections Truly Minimally Invasive? A Propensity Score Matching Analysis(2017) COELHO, Fabricio Ferreira; KRUGER, Jaime Arthur Pirola; JEISMANN, Vagner Birk; FONSECA, Gilton Marques; MAKDISSI, Fabio Ferrari; FERREIRA, Leandro Augusto; D'ALBUQUERQUE, Luiz Augusto Carneiro; CECCONELLO, Ivan; HERMAN, PauloBackground: Hybrid liver resection is considered a modality of minimally invasive surgery; however, there are doubts regarding loss of benefits of laparoscopy due to the use of an auxiliary incision. We compared perioperative results of patients undergoing hybridxopen and hybridxpure laparoscopic resections. Methods: Consecutive patients undergoing liver resection between June 2008 and January 2016 were studied. Study groups were compared after propensity score matching (PSM). Results: Six hundred forty-four resections were included in the comparative analysis: 470 open, 120 pure laparoscopic, and 54 hybrids. After PSM, 54 patients were included in each group. Hybridxopen: hybrid technique had shorter operative time (319.5108.6x376.2 +/- 155.8 minutes, P=.033), shorter hospital stay (6.0 +/- 2.7x8.1 +/- 5.6 days, P=.001), and lower morbidity (18.5%x40.7%, P=.003). Hybridxpure laparoscopic: hybrid group had lower conversion rate (0%x13%, P=.013). There was no difference regarding estimated blood loss, transfusion rate, hospital stay, complications, or mortality. Conclusions: Hybrid resection has better perioperative results than the open approach and is similar to pure laparoscopy. The hybrid technique should be considered a minimally invasive approach.
