RESUMO

INTRODUCTION: Transanal endoscopic microsurgery (TEM) was developed as a less aggressive alternative treatment for rectal lesions (mainly adenomas and adenocarcinomas). However, its use for other rectal lesions has become more frequent, trying to reduce the morbidity associated with more invasive techniques. The aim of this study is to describe our experience in the use of TEM in other rectal lesions. METHODS: Retrospective and descriptive study including patients operated with TEM (from June 2008 to December 2016) for the treatment of rectal lesions different from adenomas or adenocarcinomas. RESULTS: Among the 138 patients treated by TEM in our department, 10 patients were operated on for rectal lesions other than adenomas or adenocarcinomas. Rectal lesions were 3neuroendocrine tumours, a neuroendocrine tumour metastasis, a rectal stenosis, a cloacogenic polyp, an endometrioma, a retrorrectal tumour, a presacral abscess and a lesion in the rectovaginal septum. Mean operative time was 72min and postoperative stay was 4.2 days. Only one patient needed a reoperation, due to rectal bleeding. CONCLUSIONS: TEM could be a useful tool for the treatment of rectal lesions different from adenomas or adenocarcinomas, potentially decreasing the morbidity associated with more aggressive surgical techniques.

RESUMO

Introducción: El tratamiento quirúrgico de las afecciones del recto bajo se encuentra en permanente revisión intentando mantener una adecuada función de continencia y urogenital. Una opción reciente es el abordaje microquirúrgico transanal. El objetivo del trabajo es evaluar una serie de pacientes tratados mediante dicho abordaje, analizando indicaciones, resultados inmediatos y alejados. Material y método: Se seleccionaron 41 pacientes operados en el período comprendido entre febrero de 2009 y febrero de 2015. Resultados: En 41 pacientes, las afecciones tratadas fueron: pólipos, 22; cáncer de recto, 14; estenosis de anastomosis, 2; absceso retrorrectal, 1; endometriosis, 1; poliposis adenomatosa familiar, 1. Los pacientes con pólipos llegaron a consulta: por primera vez, 15; recidivados, 4; segunda recidiva, 2; tercera recidiva, 1. Los procedimientos realizados fueron: resección local, 29; microcirugía transanal transabdominal (TATA), 6; dilatación de estenosis, 4; biopsia transrectal, 3; drenaje de absceso retrorrectal, 1; control de hemorragia, 1; colocación de stent, 1. En cáncer de recto: resección local, 7; biopsia transrectal, 2; TATA, 4; colocación de stent, 1. El tiempo operatorio promedio fue 48,6 minutos, y la estadía hospitalaria promedio 2,21 días. De los 29 pacientes en quienes se realizó resección local, fueron controlados 25 durante un período de 6 a 72 meses. Se complicaron 11 pacientes, sin mortalidad ni recidivas locales. Conclusiones: Este abordaje permite tratar lesiones del recto y último segmento del colon sigmoides. Otorga mejor visión permitiendo una disección más exacta, mejorando resultados postoperatorios inmediatos y alejados en patología benigna y maligna, minimizando la posibilidad de recidivas. (AU)


Introduction: The surgical treatment of conditions located at the low rectum is in constant review, triying to maintain proper urogenital and continence function. One of the most recent options is the transanal microsurgical. The aim of this paper is to analyze a series of patients treated with this approach, its indications, immediate and long term results. Material and Methods: 41 patients were analyzed retrospectively in the period between February 2009 and February 2015. Results: In these patients, treated conditions were polyps: 22; rectal cancer: 14; anastomotic stricture: 2; retrorectal abscess: 1; endometriosis: 1; familial adenomatous polyposis: 1. Patients affected with polyps reached the first consultation in 15 opportunities; 4 on first recurrence; 2 with second recurrence; 1 with third recurrence. The procedures were 29 local resections; 6 transanal transabdominal resections (TATA); 4 dilations of stenosis; 3 transrectal biopsies; 1 retrorectal abscess drainage; 1 hemorrhage control; 1 stent placement. In rectal cancer were: 7 local resection; 2 transrectal biopsies; 4 TATA; 1 stent placement. Mean operative time was 48.6 minutes and mean hospital stay was 2.21 days. Of the 29 patients in whom local resection was performed, 25 were controlled for a period of 6 to 72 months. 11 patients were complicated; no deaths or local recurrences were registered. Conclusions: This approach allows to treat lesions located throughout the rectum and the last segment of sigmoid colon. A better insight is obtained allowing a more accurate dissection, thus improving the immediate and remote postoperative results and minimizes the possibility of recurrence, particularly when it comes to benign conditions.

RESUMO

La microcirugía endoscópica transanal (TEM, por sus siglas en inglés) es una técnica que se ha desarrollado desde los años 80 y tiene múltiples indicaciones. La cirugía transanal mínimamente invasiva (TAMIS, por sus siglas en inglés) se ha introducido como un enfoque alternativo al TEM, con las mismas indicaciones y algunas ventajas. Se reporta aquí el primer caso en Costa Rica de TAMIS, practicada exitosamente en un paciente de 85 años con una tumoración rectal de 4 cm de diámetro.


Transanal Endoscopic Microsurgery (TEM, for its acronym in English) is a technique developed in the 80s, which has many uses. Transanal Minimally Invasive Surgery (TAMIS, for its acronym in English) has been introduced as an alternative approach to TEM, with the same indications and some advantages. The case of an 85-yearold male with a 4 cm in diameter rectal tumor successfully resected by TAMIS is herein reported, which is the first case treated in this manner in Costa Rica.

RESUMO

INTRODUCCIÓN. El objetivo del presente estudio fue evaluar la indicación y los resultados de la microcirugía endoscópica transanal (TEM) para el tratamiento de los tumores benignos y malignos del recto, en el Centro Nacional de Cirugía de Mínimo Acceso (La Habana). MÉTODOS. Se realizó una amplia revisión bibliográfica acerca del manejo actual de los tumores benignos y malignos de recto mediante TEM y se evaluaron los resultados de dicha técnica en un período de 4 años en el Centro Nacional de Cirugía de Mínimo Acceso. RESULTADOS. En el período estudiado se operaron 33 pacientes mediante esta técnica. Las principales indicaciones de la TEM fueron los adenomas (72,8 por ciento). El tiempo quirúrgico promedio fue de 189,1 min; se usó transfusión intraoperatoria en 4 pacientes (12,1 por ciento) y la estancia hospitalaria fue de 2,5 días. Las principales complicaciones transoperatorias fueron el sangramiento y la perforación en la cavidad peritoneal. Las complicaciones posoperatorias fueron la fístula rectovaginal, el sangramiento y la dehiscencia. El seguimiento de los pacientes osciló entre 1 y 54 meses (media 28,3), y se encontraron 2 recidivas locales en el grupo de los adenomas. CONCLUSIONES. La TEM es un método seguro y eficaz para el tratamiento de los tumores benignos y malignos del recto (en estadios iniciales). Es la técnica de elección en grandes adenomas rectales y cánceres de recto con estadios pT1 localizados en toda la ampolla rectal. Tiene todas las ventajas de la cirugía de mínimo acceso; los resultados de recidiva son similares a los de la cirugía abdominal y no tiene complicaciones de disfunción urinaria o sexual y las de incontinencia fecal son mínimas(AU)


INTRODUCTION: The aim of present study was to assess the indication and the results of transanal endoscopic microsurgery (TEM) for treatment of rectal benign and malign tumors in National Center of Minimal Access Surgery in Havana city. METHODS: A comprehensive review of literature was made on present managing of rectal benign and malign tumors by TEM and results of such technique were assessed during 4 years in National Center of Minimal Access Surgery. RESULTS: During study period 33 patients were operated on by this technique. Main indications of TEM were the presence of adenomas (72,8 percent). Mean surgical time was of 189,1 minutes; in 4 patients ( 12,1 percent) transoperative transfusion was used, and hospital stay was of 2,5 days. Main transoperative complications were the rectovaginal fistula, bleeding and dehiscence. Follow-up of patients fluctuates between 1 and 54 months (mean 28,3) with 4 local relapses in adenoma group. CONCLUSIONS: TEM is a safe and effective method for treatment of rectal benign and malign tumors (in early stages). It is the choice technique for the big rectal adenomas and rectum cancer with pT1 stages located in all the ampulla of rectum. It has all advantages of the minimal access surgery; relapse results are similar to that of abdominal surgery without complications of urinary or sexual dysfunction and that of fecal incontinence are minimal(AU)
