ABSTRACT

Antecedentes: La polipectomía endoscópica (PE) es una herramienta habitual en el campo de la coloproctología. La misma ofrece un desafío al residente más aún cuando son pólipos difíciles (mayores de 20 mm). La bibliografía es escasa y no concluyente en lo que respecta a la curva de aprendizaje de este procedimiento. Objetivos: analizar la eficacia y complicaciones de la (PE) en pólipos difíciles de colon realizadas por médicos residentes en coloproctología, comparando sus resultados con los de la bibliografía internacional. Pacientes y métodos: Durante el periodo 1 de junio de 2009 al 31 de mayo del 2010 se efectúa el análisis retrospec­tivo de las polipectomías endoscópicas difíciles realizadas por un médico residente de su último año de formación bajo supervisión de un tutor. Se evalúan las siguientes variables: el tamaño, patología y complicaciones. Resultados: Se realizaron 1303 colonoscopias. Se encontraron 34 pólipos mayores a 20 mm en 34 pacientes, realizando pe en 24 casos de los cuales el residente pudo realizar el 95,8%. La edad media fue de 63 años. 15 del sexo masculino y 9 femeninos. El tamaño promedio fue 28 mm. El tiempo medio fue de 47 minutos. Displasia leve fue reportada en el 66,4%, grave en 29.4 %, cáncer invasor en 4,2 %. Complicaciones: un paciente presento un sangrado que se resuelve endoscópicamente colocando clips. No se registraron perforaciones ni síndromes post polipectomias. Conclusiones: Con una técnica adecuada y una selección cuidadosa de los casos, las polipectomías endoscópicas de pólipos de gran tamaño pueden ser realizadas con seguridad y eficacia por residentes con una adecuada curva de entrenamiento.


Background: the endoscopic polypectomy (EP) is a widespread practice in the coloproctology field. It is usually seen as a challenge by the resident, and it is seen even more challenging when operating on difficult polyps (bigger than 20 mm). The available literature is Iittle and it is not conclusive regarding the learning curve of this procedure. Objectives: analyse the efficiency and complications of the EP practiced on difficult polyps performed by residents specialized in coloproctology, and compare the outcome with the international literature available. Patients and Techniques: the retrospective analysis ­from 1st of June 2009 to 31 st of May 2010- of the EP practiced on difficult polyps done by a senior resident supervised by his mentor; considering the following indicators: size, pathology and complications of the polyp. Results: 1303 colonoscopies performed. 34 polyps bigger than 20 mm were found in 34 patients: EP was practiced on 24 cases of which the resident was able to accomplish the 95.8%. The median age of patients was 63 years old. 15 of which were males and 9 females. The average size of the polyp resulted in 28 mm. The median time of the practice was 47 minutes. The 66.4% of the cases indicated moderate dysplasia, the 29.4% acute dysplasia and the rest 4.2% invader cancer. Complications: a patient bleeding. No perforations nor post polypectomies syndroms were observed. Conclusions: With an appropiate technique and a carefuI case selection, the endoscopic polypectomies of big size polyps can be efficiently performed by residents with an adequate training curve.

ABSTRACT

Introducción: la obstrucción aguda colónica es una situación que requiere un tratamiento urgente y tiene elevada morbi-mortalidad. Las prótesis metálicas autoexpandibles, lograron un lugar en el armamento terapéutico. Se pueden colocar en forma "definitiva" o como "puente a la cirugía electiva". Las ventajas son reducción de la morbi-mortalidad, evitan cirugías de urgencia no apropiadas. Objetivo: Evaluar la factibilidad del uso de las prótesis, en obstrucción colorrectal, revisión de aspectos técnicos, tasas de éxito y complicaciones. Material y Métodos: Se analizaron todos los pacientes con obstrucción colorrectal ingresados en el Servicio de Coloproctología del Hospital Británico entre Junio 2007 y Junio del 2009, los datos fueron vertidos en una base Excel 2007. Se realizó un análisis, retrospectivo, observacional descriptivo y longitudinal. Las variables analizadas fueron: diagnóstico primario, localización de la obstrucción, intención de colocación de la prótesis, evaluación del éxito terapéutico, y complicaciones del procedimiento. Resultados: Sobre 13 pacientes con obstrucción colorrectal, en 11 (84,6 por ciento) se colocaron 15 PMA, con resolución del cuadro agudo. La edad media fue de 66 años. El 61 por ciento (8 pacientes) fueron de sexo masculino. El éxito técnico fue de 84,6 por ciento (11 pacientes), en 3 como "puente" a cirugía electiva y en 8 en foma definitiva. El éxito terapéutico fue del 100 por ciento. Las complicaciones fueron suboclusión en 1 paciente y migración en 2 pacientes con patología benigna. Conclusión: la colocación de las PMA, son eficaces y seguras con resultados preliminares que refuerzan las ventajas de los procedimientos mini-invasivos.


Background: Acute colonic obstruction is a situation that requires urgent treatment and has high morbidity and mortality. The self-expandable metallic stents achieved a place in the therapeutic armamentarium. May be placed in a “palliative” or “bridge to elective surgery”. The advantages are reducing morbility and mortality, prevent inappropriate emergency surgeries. Objective: To evaluate the feasibility of using prosthetics in colorectal obstruction, review of technical aspects, success rates and complications. Method: we analyzed all patients with colorectal obstruction admitted to the Colorectal Service at the British Hospital between June 2007 and June 2009, data were analyzed in a database Excel 2007. An analysis, retrospective, observational, descriptive was performed and the variables analyzed were: primary diagnosis, location of obstruction, self-expandable metallic stent, assessment of therapeutic success and complications of the procedure. Results: About 13 patients with colorectal obstruction in 11 (84.6 per cent) were placed 15 self-expandable metallic stents, with resolution of acute disease. The mean age was 66 years. 61 per cent (8 patients) were male. Technical success was 84.6 per cent (11 patients) in 3 as a "bridge" to elective surgery and 8 eight in final forms or palliative. Treatment success was 100 per cent. Complications were partial occlusion in 1 patient and migration in two patients with benign disease. Conclusion: The placement of the self-expandable metallic stents, are effective and safe with preliminary results that reinforce the advantages of mini-invasive procedures.

ABSTRACT

A retrospective descriptive study on the relative frequency of surgical site infection (SSI) among 235 operated cancer patients at Chong Hua Hospital was done covering the period from January 1991 up to May 1993. SSI occurred in 9.4 percent (22/235). There was a significant increase in SSI as the population became older (p=0.01). Dirty operations had a significantly higher infection rate of 50 percent (2/4) compared to 8.7 percent (20/211) for the rest (p=0.45). Clean operations had a significantly lower infection rate of 2.5 percent (3/121) compared to 16.7 percent (19/114) for the rest. There was no difference in SSI between early and late stage cancer cases. Operations in the alimentary tract had a significantly higher infection rate of 19.3 percent (11/57) compared to 6.4 percent (11/172) for operations on the other sites (p=0.004). Operations on solf tissues, breast and thyroid had a signifanctly lower rate of 4.6 percent (4/87) compared to 12.7 percent (18/142) for operations on other sites (p=0.045).(Author)
