ABSTRACT

Aim of the study: Hepatocellular carcinoma (HCC) is a lethal malignancy with heterogeneous behavior determined by liver function, clinical presentation and treatment response. Peritoneal metastasis (PM) from HCC is rare and management is challenging. We aim to report a cohort of patients with advanced HCC and describe demographic characteristics, treatment and outcomes of patients with PM. Material and methods: We analyzed data from a retrospective cohort of patients with HCC. Patients with PM were analyzed individually. Baseline characteristics, treatment strategy and median overall survival (OS) with 95% confidence interval (CI) were reported. Results: 238 patients with advanced HCC were evaluated. Eleven patients had PM: 7 patients were treated with systemic treatment and 4 were treated with upfront peritonectomy followed by systemic treatment at recurrence. These 4 patients had well-preserved liver function and low disease burden and were younger compared to the total cohort. The median time to recurrence after peritonectomy was 30.25 months (interquartile range [IQR]: 13.53-46.92): 3 of them presented peritoneal recurrence (2 with diffuse peritoneal spread and 1 with concomitant hepatic recurrence) and 1 presented pulmonary recurrence. Overall, patients with PM showed similar OS compared to patients with other metastatic sites (11.8 months; 95% CI: 1.5-19.8 vs. 8 months; 95% CI: 6.7-10, p = 0.901). Patients with PM treated with upfront surgery had a median OS of 60 months (95% CI: 16.7-not reached). Conclusions: Resection of PM from HCC may provide long-term survival in selected patients. A multidisciplinary approach is the optimal strategy for managing PM from HCC.

ABSTRACT

INTRODUÇÃO: O método laparoscópico é efetivo no diagnóstico e verificação do estádio das neoplasias malignas intra-abdominais e permite a exploração do comprometimento da serosa gástrica, folhetos peritoneais parietal e visceral, fígado, epíplons, cavidade pélvica e outros órgãos da cavidade abdominal, e coleta de líquido ascítico. OBJETIVO: Relatar a técnica do método videolaparoscópico e como realizá-lo com vistas à carcinomatose peritoneal. MÉTODO: Após a introdução sob visão direta do trocarte na região da cicatriz umbilical, esvazia-se a ascite ao máximo. Coleta-se fluido peritoneal para realização de exame citológico, evitando-se contaminação com sangue para não diminuir a sensibilidade do método. Se não houver ascite, pode-se realizar o lavado peritoneal. As liberações de bridas e aderências podem ser realizadas previamente à exploração da cavidade e também várias biópsias do peritônio parietal, diafragma, omento e cavidade pélvica para confirmação. Para se determinar se o paciente é candidato à peritoniectomia e/ou quimioterapia hipertérmica intra-abdominal, realiza-se o índice de carcinomatose peritoneal, tendo-se por base a distribuição e o tamanho dos nódulos. Para que isto ocorra é essencial a utilização de mesa operatória com capacidade de se mover para as posições de Trendelenburg, proclive e laterais. CONCLUSÃO: O método laparoscópico apresenta-se bom para se avaliar ascite, metástases hepática e peritoneal, podendo atingir eficiência, sensibilidade e especificidade de até 100 por cento para os referidos atributos. Ele deve ser realizado quando existir suspeita clínica de difusão intraperitoneal da neoplasia não confirmada pelos métodos diagnósticos por imagem.


INTRODUCTION: The laparoscopic procedure is effective in the diagnosis and verification of level of intra-abdominal malignancies and allows exploration of commitment of the serosa, parietal and visceral peritoneum, liver, epiíplon, pelvic cavity and other organs of the abdominal cavity, and permit to deal with ascites. AIM: To describe laparoscopic technique and method to accomplish the peritoneal carcinomatosis status and indications for peritoniectomies. METHODS: After the introduction of the trocar under direct vision in the region of the umbilicus it is possible to empty ascites to the fullest, and collect material for cytological examination, avoiding contamination with blood. If there is no ascites, peritoneal lavage can be performed. Releases adhesions and adhesions can be also done prior to the operation of the cavity and also several biopsies of parietal peritoneum, diaphragm, omentum and pelvic cavity for confirmation. To determine whether the patient is a candidate for peritoniectomy and / or intra-abdominal hyperthermic chemotherapy, it can permit the realization of index of peritoneal carcinomatosis. For this to occur is essential to use the operating table with the ability to move the positions of Trendelemburg, proclivity and sides. CONCLUSION: The laparoscopic method is good to evaluate ascites, hepatic and peritoneal metastases, and may achieve efficiency, sensitivity and specificity of 100 percent for these attributes. It should be performed when there is clinical suspicion of intraperitoneal dissemination, but no diagnostic imaging confirmation.

ABSTRACT

Racional - A perda de grande extensão do intestino delgado ocorre em diversas situações clínicas, geralmente relacionadas à necessidade de ressecção cirúrgica. A função primordial do intestino é absorção de nutrientes; sua integridade é fundamental para a sobrevivência de todo e qualquer animal...
