Ultrasound imaging versus conventional histopathology in diagnosis of periapical lesions of endodontic origin: A comparative evaluation.

Context: Accurate assessment of periapical status is critical in diagnosis, treatment planning, and evaluation of healing. Novel imaging modalities like sonography offer promising results with reduced radiation risks. Aims: To evaluate the potential of ultrasound imaging technique together with the application of color Doppler to differentiate between periapical lesions of endodontic origin. Materials and Methods: Twenty patients with periapical lesions of endodontic origin who were already scheduled for undergoing endodontic surgery were examined further using sonography. Color Doppler was performed to assess blood flow. Information on the size of the lesion, its content, and vascular supply was gained and recorded by means of ultrasound images. The sonographic images were analyzed and discussed with an expert sonologist, and a tentative diagnosis between a periapical cyst and periapical granuloma was made. Endodontic surgery and histopathological examination was done for each case and the results were compared. Results: The sonograms revealed the lesions within the bone in three dimensions and their contents, that is, fluids or tissues or blood vessels. Measurements of the periapical lesions in three dimensions were also obtained. Of the twenty cases studied, ultrasound could detect periapical granulomas in all 9 cases and radicular cysts in all 11 cases. Conclusion: Ultrasound imaging had the potential to be used for the evaluation of periapical lesions of endodontic origin. However, further studies are required to establish a definite correlation.

Electrocoagulación monopolar del meso apendicular en apendicectomía laparoscópica: experiencia en el Hospital Central de Maracay / Monopolar electrocoagulation of the meso appendix in laparoscopic appendectomy: experience in the Hospital Central of Maracay

Evaluar la electrocoagulación monopolar del meso apendicular como una herramienta útil en apendicectomía laparoscópica en pacientes con apendicitis aguda, ingresados al servicio de Cirugía General del Hospitla Central de maracay. Diseño no experimental de corte transversal, donde la población estuvo conformada por los pacientes que acudieron a la emergencia del Hospital Central de Maracay durante el período enero-julio de 2010. Para la recolección de datos se utilizó: libro de registro, historia clínica y encuesta postoperatoria. Se analizaron por estadística descriptiva, donde se obtuvo que el tiempo quirúrgico promedio fue de 60 minutos, no se presentaron complicaciones tardias, el tiempo de hospitalización fue 2 días y los pacientes se incorporaron a sus actividades físicas en 10 días. La electrocoagulación monopolar del meso apendicular es una herramienta útil en pacientes con apendicitis aguda, ya que abarata costos, y es segura.

Assess the monopolar electrocoagulatión of the meso appendix as a useful tool in laparoscopic appendectomy in patients with acute appendicitis, admitted at service of General Surgery of the Hospital Central de Maracay. This is a non-experimental design of cross section, where the population was formed by patients attending the Hospital Central de Maracay emergency during the period between January and July 2010. Usted for data collection: clinic record and postoperative surgery. They were analyted by descriptive statistics, founding that average surgical time was 60 minutes, there were not late complications, hospitalization time was 2 days, and patients were incorporated into their physical activities in 10 days. Monopolar electrocoagulation of the meso appendicular is a useful tool in patients with acute appendicitis, as it cheaper cost, and is safe.
