[Experimental microendoscopy of the milk duct system (ductoscopy)].
According to recent reports, the microendoscopic lactiferous duct investigation (ductoscopy) could improve diagnosis in case of pathological nipple discharge. However, the description of a reproducible and reliable methodology, suitable for thorough evaluation of the lactiferous duct is missing so far. Therefore, the pressure study developed a procedure, that may serve now as an experimental basis for further clinical evaluation. Access to the mamillary duct is primarily gained using atraumatic flexible teflon catheters. Corresponding to the diameter of the duct, either a semirigid 0.87 mm fiberendoscope can be successfully introduced via a 1.2 mm catheter, or a flexible 0.50 mm fiberendoscope via a 1.0 mm catheter. A controlled distension using few milliliters of ringer's lactate is the prerequisite for clear visualization of the intraductal space and protection against iatrogenic wall lesions. Metal microtocars are available as prototypes. They carry a somewhat higher risk to perforate, but are advantageous when pointing at an intraductal structure and using the microtrocar as a mark for microdochectomy.
