Initial experience of video endoscopic inguinal Lymphadenectomy in a center located at northeast brazilian region

ABSTRACT Introduction: Video endoscopic inguinal lymphadenectomy - VEIL - has emerged as an alternative to reduce post-surgical complications (PSC) in patients with penile cancer submitted to inguinal lymphadenectomy (IL). In some series, these PSC are observed in more than 50% of patients. The objectives of the present study are to describe the initial experience of VEIL in a Hospital in Teresina, PI, Brazil, and to analyze PSC incidence. Material and Methods: Retrospective descriptive study of patients submitted to VEIL from March 2014 to November 2015. Data were collected regarding surgical time, bleeding, complications, lymph node number, conversion, global complications, drainage time, cellulitis, lymphocele, cutaneous necrosis, miocutaneous necrosis and hospitalization time. Results: 20 lower limbs of 11 patients were operated. Mean age was 51.4 (24-72) years. Mean surgical time was 85 (60-120) minutes. No patient showed intrasurgical complications, bleeding > 50 mL or conversion. Three surgeries evolved with lower limb edema, 2 with lymphoceles and one patient had cutaneous necrosis and another bulging of surgical wound. Mean time of hospitalization was 4 (2-11) days. A mean of 5.8 (1-12) lymph nodes were dissected in each surgery. Conclusion: VEIL is a safe and easy technique with lower incidence of PSC that can be reproduced in small centers.

Three-dimensional virtual reconstruction as a tool for preoperative planning in the management of complex anorectal fistulas / Reconstrução virtual tridimensional como ferramenta de planejamento pré-operatório de fístulas anais complexas

ABSTRACT The making of three-dimensional virtual models is a promising technology in preoperative planning, but that is not used in the treatment of anorectal fistulas. The objective of this work is to describe the development and initial experience of the construction of a virtual three-dimensional model of the pelvic anatomy of a patient, allowing the exact identification of the relationships between the fistulous tracts of complex anorectal fistulas and the other pelvic structures. An MRI was performed on this patient, and the images were exported to the Vitrea fX Workstation® software. A radiologist did the analysis and segmentation of the images that were then sent to a three-dimensional image processor (Meshlab v. 1.3.3 - ISTI - CNR Research Center, Pisa University, Italy®). The final 3D color image was analyzed by the surgeon and used to guide the catheterization of the fistulous pathways, the internal orifice and to assist in the identification of adjacent structures. The final three-dimensional model presented a high correlation with the intraoperative findings and facilitated the surgical planning.

RESUMO A criação de modelos virtuais tridimensionais é uma tecnologia promissora no planejamento pré-operatorio, entretanto não é utilizada no tratamento de fistulas anais. O objetivo desse trabalho é descrever o desenvolvimento e a experiência inicial da construção de um modelo virtual tridimensional da anatomia pélvica de um paciente, que permite a identificação exata das relações entre os tratos fistulosos de fistulas anais complexas e as demais estruturas pélvicas. O paciente realizou uma ressonância magnética e as imagens foram exportadas para o programa Vitrea fX software Workstation®. Um radiologista realizou a analise e segmentação das imagens que, em seguida, foram enviadas para um processador de imagens tridimensionais (Meshlab v. 1.3.3 - ISTI - CNR research center, Pisa University, Italy®). A imagem 3D colorida final foi analisada pelo cirurgião e utilizada para guiar a cateterização dos trajetos fistulosos e orifício interno e para auxiliar na identificação das estruturas adjacentes. O modelo tridimensional final apresentou alta correlação com os achados intraoperatorios e facilitou o planejamento cirúrgico.

Exenteração pélvica para câncer do colo uterino recidivado pós-radioterapia: experiência de um centro terciário do Nordeste brasileiro / Post-radiotherapy pelvic exenteration in relapsed cervical cancer: experience of a tertiary health service in the northeast of Brazil

OBJETIVO: analisar complicações, morbidade, mortalidade e sobrevida num grupo de pacientes com câncer de colo uterino com recidiva pélvica central submetidas à exenteração pélvica pós-tratamento primário com radioterapia. MÉTODOS: estudo retrospectivo de uma série de 16 casos de exenteração pélvica pós-tratamento primário com radioterapia. Foi realizada estatística descritiva, curva de sobrevida pelo método de Kaplan-Meier e análise de regressão linear múltipla para avaliar fatores prognósticos. RESULTADOS: dezesseis pacientes foram submetidas à exenteração pélvica. O carcinoma epidermoide, o estádio IIb e o grau indiferenciado foram as condições mais frequentes. A recidiva tumoral pós-operatória ocorreu na metade dos casos. Onze pacientes apresentaram complicações perioperatórias ou pós-operatórias e as mais frequentes foram infecções pélvica e da ferida operatória e fístulas urinárias. A sobrevida global foi de 64,3 por cento, com um seguimento mediano de 11 meses. A análise de regressão linear múltipla não revelou fatores prognósticos significativos na sobrevida das pacientes. CONCLUSÕES: a taxa de sobrevida foi de 64,3 por cento. Nenhum fator associado a pior prognóstico foi encontrado nesta série.

PURPOSE: to analyze complications, morbidity, mortality and survival rate in a group of patients with cervical cancer with central pelvic relapse after primary radiotherapy treatment. METHODS: retrospective study of a series of 16 cases of pelvic exenteration after primary radiotherapy treatment. Descriptive statistics, survival curve through Kaplan-Meier's method, and regression analysis to evaluate prognosis were performed. RESULTS: sixteen patients have undergone pelvic exenteration. Epidermoid carcinoma, IIb stage and undifferentiated grade were the most frequent conditions. Post-operatory tumor relapse occurred in half the cases. Eleven patients presented peri or post-surgical complications, the most frequent being pelvic infection, that of the surgical wound, and urinary fistulae. Global survival rate was 64.3 percent, with average follow-up of 11 months. Regression analysis did not detect any significant prognosis factor for the patient survival. CONCLUSIONS: the survival rate was 64.3 percent. No particular factor associated to poor prognosis has been found in the present series of cases.
