Primary tumors of the ischiorectal fossa are rare, they can be congenital, acquired or neoplastic. Accurate diagnosis often cannot be done preoperatively and imaging studies such as computed tomography and especially magnetic resonance imaging can define the size and anatomical relationships of the lesions. Surgical treatment is challenging because of difficult access of the region which is preferably performed by posterior approach. We describe the etiology, diagnosis and operative technique of tumors of the ischiorectal fossa.
Several surgical options are described for the treatment of anorectal fistulas, particularly in complex cases where recurrence rates and the possibility of postoperative incontinence are still high. The aim of this study is to describe the use of FILAC technique (Fistula – Tract Laser Closure) minimally invasive and preservation sphincter technique. FILAC has been described in the literature as an option in the management of anorectal fistula.
Alves Filho EF, Costa PFO, Guerra JC. Transanal minimally invasive surgery with single-port (TAMIS) for the management of rectal neoplasms: a pilot study. J Coloproctol, 2012;32(4): 402-406. ABSTRACT:Transanal endoscopic microsurgery (TEM) has been used since the 1980's for the treatment of selected rectal cancers, with clear benefits regarding morbidity and mortality, and good oncological outcomes when compared to radical surgery and conventional local resections. The high cost of equipment and the need for long learning curve did not allow the spread of the technique. The aim of this study was to describe the technical characteristics and outcomes of 4 patients operated by this technique, 3 with histologically confirmed adenomas and 1 carcinoid rectal tumor, with no recurrence after an average follow-up of 12 months. The use of single port devices for transanal surgery is a safe method with good oncological results and allows a faster learning curve, by the similarity with conventional laparoscopic procedures and the availability of devices commonly used in laparoscopy. Keywords: colorectal surgery; rectal neoplasms; TAMIS; laparoscopy.ReSumo: A microcirurgia endoscópica transanal (TEM) é usada desde a década de 80 para o tratamento de neoplasias retais selecionadas, com claros benefícios relacionados à mortalidade e morbidade, e com bons resultados oncológicos, em comparação à cirurgia radical e a ressecções locais convencionais. O custo alto de equipamento de TEM e a necessidade de uma curva de aprendizagem longa ainda não permitiram a propagação da técnica. O objetivo deste estudo foi descrever a técnica cirúrgica e os desfechos oncológicos em 4 pacientes operados por esta técnica, 3 com diagnóstico final de adenomas e 1 de tumor carcinoide, sem recorrência após seguimento médio de 12 meses. A utilização de dispositivos de portal único para a cirurgia transanal é um método seguro e com bons resultados oncológicos, permitindo uma curva de aprendizado mais rápida pela semelhança com os procedimentos laparoscó-picos convencionais e pela disponibilidade de dispositivos comumente utilizados em laparoscopia.Palavras-chave: cirurgia colorretal; neoplasias retais; TAMIS; laparoscopia.
Carcinoid tumors are rare. They may appear in the entire gastrointestinal and respiratory tracts, with single or multiple occurrences. Prognosis is dependent on the size and location. Symptoms may appear in carcinoid syndrome, related to active substances, especially serotonin. One important aspect associated with these tumors and usually ignored is fibrogenesis. This is a case report of a patient with carcinoid tumor of the terminal ileum, treated by laparoscopy, associated with fat and fibrosis infiltration.
Tumores carcinoides são pouco frequentes, podem surgir em todo o trato gastrointestinal e respiratório, podem ser únicos ou múltiplos. O prognóstico depende do tamanho e da localização do tumor. Podem ocorrer sintomas relacionados à síndrome carcinoide, decorrente da produção de substâncias ativas, em especial serotonina. Um aspecto comumente ignorado associado a estes tumores é a estimulação da fibrogênese. Relatamos um caso de tumor carcinoide de íleo, tratado por videolaparoscopia, associado à infiltração fibroadiposa
TAMIS Rectal cancerVloc Partial excision of mesorectum a b s t r a c t Background: Transanal Minimally Invasive Surgery has proven to be a viable alternative in the treatment of rectal tumors; however, rectal wound closure can be challenging. We describe our experience with this procedure using the vloc suture device. Resume: Eight successful Transanal Minimally Invasive Surgery with primary wound closure using vloc were performed in 5 men, 62 years mean age; all cases had pre-operative diagnosis of adenoma with high-grade dysplasia. The surgical anatomic-pathologic results showed 6 adenomas with high-grade dysplasia and 2 well differentiated adenocarcinomas, limited to the upper third of the submucosa (pT1SM1) without lymphatic or vascular invasion. All lesions were resected with negative margins. No patient reported during follow-up rectal pain, fecal incontinence or bleeding. Conclusion: The use of vloc in rectal wound closure during Transanal Minimally Invasive Surgery is secure and facilitates the procedure. TAMIS com excisão parcial do mesorreto e fechamento primário da ferida retal usando vloc Palavras-chave: TES TAMIS Câncer retal Vloc Excisão parcial do mesorreto r e s u m o Tema: Cirurgia Minimamente Invasiva Transanal (TAMIS) tem provado ser uma alternativa viável para o tratamento de tumores do reto, porém o fechamento da ferida rectal pode ser desafiadante. Nós descrevemos nossa experiência com este procedimento utilizando o dispositivo de sutura vloc.Resumo: Oito TAMIS foram realizados com sucesso com o fechamento primário da ferida usando vloc, cinco homens, com idade média de 62 anos, todos os casos tiveram diagnóstico pré-operatório de adenoma com displasia de alto grau. Os resultados anátomo-patológicos j coloproctol (rio j). 2 0 1 5;3 5(2):100-105 101 pós-operatório demonstraram: 6 adenomas com displasia de alto grau e 2 adenocarcinomas bem diferenciados, limitado ao terço superior da submucosa (pT1SM1), sem invasão linfática ou vascular. Todas as lesões foram ressecados com margens negativas. Nenhum paciente relatou durante o seguimento dor rectal, incontinência fecal ou sangramento.Conclusão: O uso de vloc no fechamento da ferida retal durante TAMIS é seguro e facilita o procedimento.
