- DOES THE DROP IN PORTAL PRESSURE AFTER ESOPHAGOGASTRIC DEVASCULARIZATION AND SPLENECTOMY INFLUENCE THE VARIATION OF VARICEAL CALIBERS AND THE REBLEEDING RATES IN SCHISTOSOMIASIS IN LATE FOLLOW-UP?(2021) SILVA-NETO, Walter de Biase; QUIRESE, Claudemiro; MOURA, Eduardo Guimaraes Horneaux de; COELHO, Fabricio Ferreira; HERMAN, PauloBackground: The treatment of choice for patients with schistosomiasis with previous episode of varices is bleeding esophagogastric devascularization and splenectomy (EGDS) in association with postoperative endoscopic therapy. However, studies have shown varices recurrence especially after long-term follow-up. Aim: To assess the impact on behavior of esophageal varices and bleeding recurrence after post-operative endoscopic treatment of patients submitted to EGDS. Methods: Thirty-six patients submitted to EGDS were followed for more than five years. They were divided into two groups, according to the portal pressure drop, more or less than 30%, and compared with the behavior of esophageal varices and the rate of bleeding recurrence. Results: A significant reduction on the early and late post-operative varices caliber when compared the pre-operative data was observed despite an increase in diameter during follow-up that was controlled by endoscopic therapy. Conclusion: The drop in portal pressure did not significantly influence the variation of variceal calibers when comparing pre-operative and early or late post-operative diameters. The comparison between the portal pressure drop and the rebleeding rates was also not significant.
- HEPATOSPLENIC SCHISTOSOMIASIS-ASSOCIATED CHRONIC PORTAL VEIN THROMBOSIS: RISK FACTOR FOR HEPATOCELLULAR CARCINOMA?(2023) DARCE, George Felipe Bezerra; MAKDISSI, Fabio Ferrari; ANDO, Sabrina de Mello; FONSECA, Gilton Marques; KRUGER, Jaime Arthur Pirola; COELHO, Fabricio Ferreira; ROCHA, Manoel de Souza; HERMAN, PauloBACKGROUND: Hepatosplenic schistosomiasis is an endemic disease prevalent in tropical countries and is associated with a high incidence of portal vein thrombosis. Inflammatory changes caused by both parasitic infection and portal thrombosis can lead to the development of chronic liver disease with potential carcinogenesis. AIMS: To assess the incidence of portal vein thrombosis and hepatocellular carcinoma in patients with schistosomiasis during long-term follow-up. METHODS: A retrospective study was conducted involving patients with schistosomiasis followed up at our institution between 1990 and 2021. RESULTS: A total of 126 patients with schistosomiasis were evaluated in the study. The mean follow-up time was 16 years (range 5-31). Of the total, 73 (57.9%) patients presented portal vein thrombosis during follow-up. Six (8.1%) of them were diagnosed with hepatocellular carcinoma, all with portal vein thrombosis diagnosed more than ten years before. CONCLUSIONS: The incidence of hepatocellular carcinoma in patients with schistosomiasis and chronic portal vein thrombosis highlights the importance of a systematic long-term follow-up in this group of patients.
- PROTOCOL FOR LIVER TRANSPLANTATION IN HILAR CHOLANGIOCARCINOMA(2021) ERNANI, Lucas; MARTINO, Rodrigo Bronze de; ANDRAUS, Wellington; FERNANDES, Eduardo de Souza Martins; MELLO, Felipe Pedreira Tavares de; ANDRADE, Ronaldo; PIMENTEL, Leandro Savattone; HADDAD, Luciana Bertocco de Paiva; COELHO, Fabricio Ferreira; HERMAN, Paulo; D'ALBUQUERQUE, Luiz Augusto CarneiroBackground: Hilar cholangiocarcinoma represents more than half of all cholangiocarcinoma cases, having poor prognosis and presenting a median overall survival after diagnosis of 12-24 months. In patients who have unresectable tumors with a better prognosis, the proposal to perform liver transplantation emerged for expanding the possibility of free margins by performing total hepatectomy. Aim: To provide a Brazilian protocol for liver transplantation in patients with hilar cholangiocarcinoma. Method: The protocol was carried out by two Brazilian institutions which perform a large volume of resections and liver transplantations, based on the study carried out at the Mayo Clinic. The elaboration of the protocol was conducted in four stages. Result: A protocol proposal for this disease is presented, which needs to be validated for clinical use. Conclusion: The development of a liver transplantation protocol for cholangiocarcinoma aims not only to standardize the treatment, but also enable a better assessment of the surgical results in the future.

- LAPAROSCOPIC LIVER RESECTION FOR BENIGN TUMORS: THE CURRENT POSITION(2021) HERMAN, Paulo; FONSECA, Gilton Marques; KRUGER, Jaime Arthur Pirola; JEISMANN, Vagner Birk; COELHO, Fabricio FerreiraBACKGROUND: 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.
- PROTOCOL FOR LIVER TRANSPLANTATION IN UNRESECTABLE COLORECTAL METASTASIS(2021) ERNANI, Lucas; FERNANDES, Eduardo de Souza Martins; MARTINO, Rodrigo Bronze de; COELHO, Fabricio Ferreira; MELLO, Felipe Pedreira Tavares de; ANDRADE, Ronaldo; PIMENTEL, Leandro Savattohe; HADDAD, Luciana Bertocco de Paiva; HERMAN, Paulo; ANDRAUS, Wellington; D'ALBUQUERQUE, Luiz Augusto CarneiroBACKGROUND: Colorectal cancer (CRC) is the third most common neoplasm, and half of the patients with CRC develop liver metastasis. The best prognostic factor for colorectal liver metastasis (CRLM) is the possibility of performing a resection with free margins; however, most of them remain unresectable. The justification for performing liver transplantation (LT) in patients with CRLM regards an increase in the number of resectable patients by performing total hepatectomy. AIM: The aim of this study was to rovide a Brazilian protocol for LT in patients with unresectable CRLM. METHOD: The protocol was conducted in four stages. RESULT: A protocol proposal for this disease is presented, which needs to be validated for clinical use. CONCLUSION: The development of an LT protocol for unresectable CRLM aims to standardize the treatment and to enable a better evaluation dos of surgical results.
- LIVER RESECTION IN BRAZIL: A NATIONAL SURVEY(2018) FONSECA, Gilton Marques; JEISMANN, Vagner Birk; KRUGER, Jaime Arthur Pirola; COELHO, Fabricio Ferreira; MONTAGNINI, Andre Luis; HERMAN, PauloBackground: Liver surgery has developed significantly in the past decades. In Brazil, the interest on it has grown significantly, but there is no study regarding its clinical practice. Despite intrinsic limitations, surveys are well suited to descriptive studies and allow understanding the current scenario. Aim: To provide an overview on the current spread of liver surgery in Brazil, focusing on groups' profile, operative techniques and availability of resources. Method: From May to November 2016, was conducted a national survey about liver surgery profile in Brazil composed by 28 questions concerning surgical team characteristics, technical preferences, surgical volume, results and available institutional resources. The survey was sent by e-mail to 84 liver surgery team leaders from different centers including all regions of the country. Results: Forty-three study participants (51.2%), from all Brazilian regions, responded the survey. Most centers have residency/fellowship programs (86%), perform and do laparoscopic procedures (91%); however, laparoscopy is still responsible for a little amount of surgeries (1-9% of laparoscopic procedures over all liver resections in 39.5% of groups). Only seven centers (16.3%) perform more than 50 liver resections/year. Postoperative mortality rate is between 1-3% in 55% of the centers. Conclusion: This is the first depiction of liver surgery in Brazil. It showed a surgical practice aligned with worldwide excellence centers, concentrated on hospitals dedicated to academic practice.
