ABSTRACT Introduction: Robotic transanal surgery (RTS) is the analog of TAMIS and represents a new focus for the advancement of transanal platforms robotic transanal surgery is sometimes referred to as robotic TAMIS. Though limited to only a few centers world-wide, experience with robotic transanal surgery has been encouraging. Most research with robotic transanal surgery has concentrated on local excision of r...
ABSTRACT Introduction: Minimally invasive surgery has revolutionized surgical management in the treatment of colorectal neoplasms, reducing morbidity and mortality, hospitalization, inactivity time and minimizing cost, as well as providing adequate oncological results when compared to the conventional approach. Robotic surgery, with Da Vinci Platform, emerges as a step ahead for its potentials. The objective of...
Abstract The treatment of rectal cancer is complex and responsible for sequelae due to the various therapeutic modalities, especially the surgical resection. The advent of minimally invasive surgery provided a faster postoperative recovery and a lower complication rate when compared to conventional surgery. The implementation of laparoscopic approach in rectal cancer was responsible for these better results, bu...
ABSTRACT Introduction: In recent years, a standardized surgical approach for low rectal cancer was proposed and adopted in many centres. The extralevator abdominoperineal excision introduce an extensive resection of the pelvic floor and demonstrated superiority if the procedure is done in the prone jack-knife position, especially regarding intraoperative perforation and circumferential resections margins. The a...
OBJETIVO: Avaliar os resultados do tratamento de GIST no INCA. MÉTODOS: Análise retrospectiva de todos os casos de GIST tratados no INCA no período de 1997 a 2009. RESULTADOS: Analisamos 146 pacientes, com média de idade de 44,5 anos e predomínio do sexo feminino. O principal sintoma foi dor abdominal. Tivemos ocorrência de segundo primário em 22% dos casos e na imuno-histoquímica, 92% foram positivos para CD11...
Introdução: O cordoma é um tumor maligno da coluna vertebral que se origina nos remanescentes ectópicos de tecido notocordial, apresentando baixa prevalência na população em geral. Tem crescimento lento, mas comportamento local agressivo. Novas técnicas empregando cirurgias mais agressivas melhoraram significativamente a expectativa de vida dos pacientes portadores de cordoma. Pacientes e Métodos: Foram revisado...
Recent progress in gastrointestinal stromal tumor's (GIST) treatment were responsible for changing GIST's natural history. Knowlegde acquirement of molecular mechanism-based systemic therapy gave rise to the development of targeted antineoplastic drugs capable of reaching outcomes that had never been reached before. The introduction of imatinib in the clinical practice not only changed GIST's patients survival ...
OBJETIVO: Descrever os achados tomográficos do tumor estromal gastrintestinal de origem gástrica. MATERIAIS E MÉTODOS: No período de janeiro de 1999 a dezembro de 2006, foram selecionados 14 pacientes com diagnóstico histopatológico e imuno-histoquímico de tumor estromal gastrintestinal gástrico que apresentavam tomografia computadorizada realizada anteriormente ao tratamento. As variáveis tomográficas analisad...
Gastrointestinal stromal tumor (GIST) has been recently the subject of considerable clinical and experimental interest. This focus is based on insights gained during the past years concerning its identification as a distinct clinical entity and the advances in knowledge about the diagnosis and management. Historically, surgery has been considered the most effective treatment in spite of its limitations. Others ...
