“…Previous studies have reported the successful treatment of rectal tumors resected by TEM using a similar design to our gasless VTEM. Their reports also revealed good results with lower complication and recurrence rates as well as shorter hospital stays [1,13,16,35,37]. These patients benefited from an effective, minimally invasive alternative to conventional surgery [35].…”

“…In sequence, Japanese surgeons have modified the VETM performing it without gas inflation. These two main modifications of the original technique reduced the equipment price in approximately US$ 50000.00 [24][25][26]39]. Despite that the literature on the local excision of rectal tumors indicates high survival rates and good results about the local control of the disease, selection criteria for patient are restrict.…”

“…In these circumstances, there is an indication for a transanal endoscopic surgery. In the absence of economic viability for the material acquisition, and surgical experience with complex methods like the TEM used by Buess [21,22] as also for the videoendoscopic transanal microsurgery (VE T M ) u s e d b y S w a n s t r o n [ 2 3 ] o r t h e videoendoscopic transanal microsurgery without inflations [17,[24][25][26] we have idealized, researched and executed a more simple technique, so called Transanal Endoscopic Operation (TEO). In the present study, the main objective is to present the TEO as a method for local transanal excision of selected rectal lesions, and to present our clinical and surgical experience with this new method, comparing the results with those obtained with the well established endoscopic techniques available in the literature.…”

Purpose: The transanal procedure for rectal cancer surgery is one of the many techniques currently available. Different techniques for local excision of rectal tumors include: conventional transanal technique, posterior access surgery, therapeutic colonoscopy, transanal endoscopic surgery. Methods: The aim of the present study is to describe a new method of transanal endoscopic resection, transanal endoscopic operation (TEO), and performed with the aid of a surgical proctoscope especially designed for this purpose and report the results obtained in 32 patients submitted to the TEO and to compare these results with those obtained with other techniques currently available. The average proportions of recurrence, postoperation complications and posterior resections were analyzed by means of a metanalysis. Data on the distance and size of rectal lesions, the operative timing and hospitalization time were distributed in graphs according to authors and techniques. Results: The results were favorable and equivalent to those described in the literature. Conclusions: The surgical proctoscope specially designed for this study is efficient and has a low cost; the TEO is easily performed with the aid of this equipment; the final results were favorable and similar to those obtained with other available techniques for endoscopic transanal intestinal resection, which are of high cost and less availability.Key words: Rectal Surgery.

Há várias técnicas de excisão local para os tumores retais: O método cirúrgico transanal convencional, acessos posteriores, colonoscopia terapêutica e operações transanais endoscópicas. O objetivo é apresentar um novo método de ressecção transanal endoscópica (Operação Transanal Endoscópica -OTE), realizada com um proctoscópio cirúrgico idealizado para o procedimento e divulgar os resultados obtidos em 32 pacientes submetidos a OTE e compará-los com as técnicas atualmente empregadas. Métodos: Foram analisadas as proporções médias da recorrência, das complicações pós-operatórias e das ressecções posteriores por meio da técnica de metanálise. Para a distância e o tamanho das lesões retais, os tempos de operação e de hospitalização, foram feitos gráficos de acordo com o autor e a técnica. Resultados: Os resultados foram favoráveis e equiparáveis aos trabalhos analisados. Conclusão: Concluiu-se que: O proctoscópio utilizado na OTE demonstrou ser eficaz e de baixo custo; 2 -A OTE mostrou-se factível; 3 -A análise dos resultados com a OTE foram satisfatórios e similares às outras técnicas de ressecções transanais endoscópicas que são de alto custo e pouco disponíveis em nosso meio.Descritores: Cirurgia Retal.
