ABSTRACT
OBJETIVO. Reportar el primer caso en Costa Rica de disección endoscópica de la submucosa (DES) de un tumor de colon. PACIENTE Y MÉTODO. Se describe el caso de un paciente de 70 años, a quien en una colonoscopia de rutina se le detecta una lesión elevada multilobulada de aproximadamente 25 milímetros localizada en ciego, cerca de la válvula ileocecal. La biopsia reveló un adenoma tubular con displasia de alto grado por lo que el paciente fue sometido a una disección en-bloc de la submucosa de la lesión por vía endoscópica. RESULTADOS. El procedimiento se realizó exitosamente sin complicaciones como sangrado o perforación. El tiempo operatorio fue de 117 minutos. El análisis histopatológico del espécimen en-bloc confirmó el diagnóstico de displasia de alto grado con márgenes verticales y horizontales libres. CONCLUSIÓN. La DES de colon es una atractiva y segura alternativa de tratamiento para resecar de lesiones premalignas y algunos tipos de cáncer temprano de colon.
OBJECTIVES. To report the first case in Costa Rica of a colon tumor removed by endoscopic submucosal dissection (ESD). PATIENT AND METHOD. We describe the case of a 70-year-old man with a multilobulated 25 millimeters tumor located in the cecum, near the ileocecal valve, detected during a routine colonoscopic check-up. The biopsy revealed a tubular adenoma with high grade dysplasia and the patient underwent an endoscopic submucosal en-bloc dissection of the lesion. RESULTS. The procedure was successfully performed without complications such as bleeding or perforation. The operative time was 117 minutes. The histopathological analysis of the en-bloc specimen confirmed the diagnosis of high grade dysplasia with negative vertical and horizontal margins. CONCLUSION. Colon ESD is an attractive and safe treatment option for the removal of premalignant lesions and some types of early colon cancer.

OBJETIVO. Reportar el primer caso de disección submucosa endoscópica (DSE) en Costa Rica y analizar el futuro impacto de esta técnica en el abordaje del cáncer gástrico precoz en este país. Pacientes y métodos. Presentamos el caso de una paciente de 67 años, quien tras una endoscopia digestiva alta por leve epigastralgia, se le encuentra una lesión elevada sésil no ulcerada (0-IIa) de aproximadamente 12 milímetros localizada en el antro hacia la curvatura mayor. Posterior al resultado histopatológico de adenocarcinoma bien diferenciado limitado a mucosa, la paciente fue sometida a una disección submucosa en una pieza (en-bloc) de la lesión por vía endoscópica. RESULTADOS. La DSE fue realizada sin ninguna complicación, como sangrado o perforación, intra o postoperatoria. El tiempo operatorio fue de 65 minutos. Con el análisis histopatológico del especimen en-bloc se confirmó el diagnóstico de adenocarcinoma intramucoso con márgenes negativos. CONCLUSIÓN. La DSE promete ser una excelente alternativa para el tratamiento curativo del cáncer gástrico precoz, siendo un método más costo-efectivo, y menos invasivo, ofreciendo una mejor calidad de vida al paciente con iguales resultados a largo plazo que la cirugía convencional a cielo abierto.
OBJECTIVES. To report the first case of endoscopic submucosal dissection (ESD) in Costa Rica and to analyze the future impact of this technique for the treatment of early gastric cancer in this country. PATIENTS AND METHODS. We present the case of a 67-year-old woman who underwent an upper endoscopy for mild epigastralgia, resulting in a 12 mm non-ulcerated sessile lesion (0-IIa) located in the antrum at the greater curvature. After biopsy confirmation of a well-differentiated adenocarcinoma limited to the mucosa, the patient underwent anendoscopic submucosal dissection for the en-bloc resection of the lesion. RESULTS. The ESD was successfully performed without intra- or postoperative complications such as bleeding and perforation. Operation time was 65 minutes. Histopathological analysis of the en-bloc specimen confirmed the diagnosis of intramucosal well differentiated adenocarcinoma with negative margins. CONCLUSION. ESD is novel alternative for the curative treatment of early gastric cancer, due to its cost-effectiveness, less invasiveness, which provides a better quality of life for the patient than that of conventional open surgery with same long-term results.

Through a period of 16 years, 108 cases of early gastric cancer (EGC) were diagnosed at Hospital Mexico, a leading teaching hospital of Costa Rica's social security system and the University of Costa Rica. It was found that in four cases, the gastric neoplasia was a second primary tumor, and in the two remaining cases, the EGC developed synchronously to another neoplasm. Two of the four metachronic EGC were preceded by a uterine cervix neoplasm on stage lla; the third one was preceded by a breast adenocarcinoma, and the fourth one by a larynx cancer in a heavy male smoker. The treatment received for the first cancer was radiation therapy only, except for the breast cancer patient in whom surgery was employed as well. One of the patients with uterine cervix cancer developed an epidermoid bronchogenic cancer 17 years after the first tumor and 8 years after her EGC. In the two male patients with synchro tumors, the EGC developed together with a squasmous cell carcinoma of esophagus, and in the remaining one the EGC appeared simultaneously with a peritoneal mesothelioma. It is important to emphasize the presence of radiation therapy in the metachronous tumors, as well as the antecedent of smoking in the patient with three primary cancers, the esophagus one, and the larynx cancer patient.
