- Dimensão da margem cirúrgica nas ressecções de metástase hepática de câncer colorretal: impacto na recidiva e sobrevida(2013) HERMAN, Paulo; PINHEIRO, Rafael S.; MELLO, Evandro S.; LAI, Quirino; LUPINACCI, Renato M.; PERINI, Marcos V.; PUGLIESE, Vincenzo; ANDRAUS, Wellington; COELHO, Fabricio F.; CECCONELLO, Ivan; D'ALBUQUERQUE, Luiz C.BACKGROUND: Approximately 50% of the patients with a colorectal tumor develop liver metastasis, for which hepatectomy is the standard care. Several prognostic factors have been discussed, among which is the surgical margin. This is a recurring issue, since no consensus exists as to the minimum required distance between the metastatic nodule and the liver transection line. AIM: To evaluate the surgical margins in liver resections for colorectal metastases and their correlation with local recurrence and survival. METHODS: A retrospective study based on the review of the medical records of 91 patients who underwent resection of liver metastases of colorectal cancer. A histopathological review was performed of all the cases; the smallest surgical margin was verified, and the late outcome of recurrence and survival was evaluated. RESULTS: No statistical difference was found in recurrence rates and overall survival between the patients with negative or positive margins (R0 versus R1); likewise, there was no statistical difference between subcentimeter margins and those greater than 1 cm. The disease-free survival of the patients with microscopically positive margins was significantly worse than that of the patients with negative margins. The uni- and multivariate analyses did not establish the surgical margin (R1, narrow or less than 1 cm) as a risk factor for recurrence. CONCLUSION: The resections of liver metastases with negative margins, independently of the margin width, had no impact on tumor recurrence (intra- or extrahepatic) or patient survival

- INFLUÊNCIA DA CAUSA DO CARCINOMA HEPATOCELULAR NA SOBREVIDA DE PACIENTES APÓS RESSECÇÃO(2016) LOPES, Felipe de Lucena Moreira; COELHO, Fabricio Ferreira; KRUGER, Jaime Arthur Pirolla; FONSECA, Gilton Marques; ARAUJO, Raphael Leonardo Cunha de; JEISMANN, Vagner Birk; HERMAN, PauloABSTRACT Background: Hepatocellular carcinoma (HCC) is the most frequent type of primary liver cancer and its incidence is increasing around the world in the last decades, making it the third cause of death by cancer in the world. Hepatic resection is one of the most effective treatments for HCC with five-year survival rates from 50-70%, especially for patients with a single nodule and preserved liver function. Some studies have shown a worse prognosis for HCC patients whose etiology is viral. That brings us to the question about the existence of a difference between the various causes of HCC and its prognosis. Aim: To compare the prognosis (overall and disease-free survival at five years) of patients undergoing hepatectomy for the treatment of HCC with respect to various causes of liver disease. Method: Was performed a review of medical records of patients undergoing hepatectomy between 2000 and 2014 for the treatment of HCC. They were divided into groups according to the cause of liver disease, followed by overall and disease-free survival analysis for comparison. Results: There was no statistically significant difference in the outcomes of the groups of patients divided according to the etiology of HCC. Overall and disease-free survival at five years of the patients in this sample were 49.9% and 40.7%, respectively. Conclusion: From the data of this sample, was verified that there was no prognostic differences among the groups of HCC patients of the various etiologies.
- Laparoscopic transthoracic liver resection(2014) KRÜGER, Jaime Arthur Pirola; COELHO, Fabrício Ferreira; PERINI, Marcos Vinícius; HERMAN, PauloINTRODUCTION: Minimally invasive laparoscopic liver surgery is being performed with increased frequency. Lesions located on the anterior and lateral liver segments are easier to approach through laparoscopy. On the other hand, laparoscopic access to posterior and superior segments is less frequent and technically demanding. AIM: Technical description for laparoscopic transthoracic access employed on hepatic wedge resection. TECHNIQUE: Laparoscopic transthoracic hepatic wedge resection on segment 8. CONCLUSION: Transthoracic approach allows access to the posterior and superior segments of the liver, and should be considered for oddly located tumors and in patients with numerous previous abdominal interventions.
- Management of variceal hemorrhage: current concepts(2014) COELHO, Fabricio Ferreira; PERINI, Marcos Vinícius; KRUGER, Jaime Arthur Pirola; FONSECA, Gilton Marques; ARAÚJO, Raphael Leonardo Cunha de; MAKDISSI, Fábio Ferrari; LUPINACCI, Renato Micelli; HERMAN, PauloINTRODUCTION: The treatment of portal hypertension is complex and the the best strategy depends on the underlying disease (cirrhosis vs. schistosomiasis), patient's clinical condition and time on it is performed (during an acute episode of variceal bleeding or electively, as pre-primary, primary or secondary prophylaxis). With the advent of new pharmacological options and technical development of endoscopy and interventional radiology treatment of portal hypertension has changed in recent decades. AIM: To review the strategies employed in elective and emergency treatment of variceal bleeding in cirrhotic and schistosomotic patients. METHODS: Survey of publications in PubMed, Embase, Lilacs, SciELO and Cochrane databases through June 2013, using the headings: portal hypertension, esophageal and gastric varices, variceal bleeding, liver cirrhosis, schistosomiasis mansoni, surgical treatment, pharmacological treatment, secondary prophylaxis, primary prophylaxis, pre-primary prophylaxis. CONCLUSION: Pre-primary prophylaxis doesn't have specific treatment strategies; the best recommendation is treatment of the underlying disease. Primary prophylaxis should be performed in cirrhotic patients with beta-blockers or endoscopic variceal ligation. There is controversy regarding the effectiveness of primary prophylaxis in patients with schistosomiasis; when indicated, it is done with beta-blockers or endoscopic therapy in high-risk varices. Treatment of acute variceal bleeding is systematized in the literature, combination of vasoconstrictor drugs and endoscopic therapy, provided significant decline in mortality over the last decades. TIPS and surgical treatment are options as rescue therapy. Secondary prophylaxis plays a fundamental role in the reduction of recurrent bleeding, the best option in cirrhotic patients is the combination of pharmacological therapy with beta-blockers and endoscopic band ligation. TIPS or surgical treatment, are options for controlling rebleeding on failure of secondary prophylaxis. Despite the increasing evidence of the effectiveness of pharmacological and endoscopic treatment in schistosomotic patients, surgical therapy still plays an important role in secondary prophylaxis.
