Uso de Sistema de terapia al vacío en cierre de gastrosquisis complicada: reporte de caso / Vacuum-assisted device in gastroschisis

La gastrosquisis constituye una patología grave neonatal que plantea un reto para el cirujano y es una emergencia quirúrgica. En la mayoría de casos, el cierre de la fascia en los casos de gastrosquisis puede realizarse primariamente o después de colocar una bolsa de Silo. Presentamos el caso de unpaciente masculino de 34 semanas por Ballard con gastrosquisis; a quien se le coloco bolsa estéril (Silo) al nacer y presentó dehiscencia parcial de lamisma y evisceración, en seis ocasiones durante un período de tres semanas. Por lo que se colocó sistema de terapia al vació sobre bolsa de plástico estéril fenestrada, realizando tres cambios y logrando el cierre completo del defecto a los 17 días. El sistema de terapia al vacío puede utilizarse comouna alternativa cuando la bolsa de Silo no puede cerrar el defecto abdominal en pacientes con gastrosquisis.

Gastroschisis is a serious neonatal pathology and a surgical emergency. A general procedure for closure of the abdominal wall defect is by primary closureor by placing a protectve ¨silo¨. We report the case of male neonate born at 34 gestatonal weeks with gastroschisis. A Silo bag was placed at birth butpresented dehiscence and partal abdominal evisceraton six tmes during a three week period. A vacuum-assisted device was used over a fenestratedsilo. Three vacuum changes were performed achieving complete closure of the abdominal wall defect in 17 days. The use of vacuum-assisted device isan alternatve when closure of the abdominal wall defect of gastroschisis cannot be achieved with the use of a silo.

Does Ultrasound-Guided Directional Vacuum-Assisted Removal Help Eliminate Abnormal Nipple Discharge in Patients with Benign Intraductal Single Mass?

OBJECTIVE: To evaluate whether the removal of an intraductal mass using an ultrasound (US)-guided directional vacuum-assisted device can eliminate symptoms in patients presenting with abnormal nipple discharge. MATERIALS AND METHODS: Between March 2004 and October 2006, 36 patients who presented with abnormal nipple discharge, underwent US-guided, 11-gauge vacuum-assisted biopsy for a benign intraductal single mass on US. The ability of the procedure to eliminate nipple discharge was evaluated by physical examination during follow-up US. Lesion characteristics, biopsy variables, and histologic features were analyzed to identify factors affecting symptom resolution. RESULTS: Of the 36 lesions, 25 (69%) were intraductal papillomas, 10 (28%) were fibrocystic changes, and one (3%) was a fibroadenoma. The nipple discharge disappeared in 69% (25 of 36) of the women at a mean follow-up time of 25 months (range 12-42 month). There was no difference in the lesion characteristics, biopsy variables, and the histologic features between groups that eliminated the symptom compared those with persistent nipple discharge. CONCLUSION: US-guided directional vacuum-assisted removal of an intraductal mass appears to eliminate nipple discharge in only 69% of patients and thus, it should not be considered as an alternative to surgical excision.
