Summary
Improving breast cancer research, ductal lavage is now more feasible. Intranipple lidocaine and imaging techniques like ductoscopy and ultrasound enhance duct cannulation success and patient comfort, making it a viable research tool.
Area of Science:
- Oncology
- Surgical Innovation
- Biomedical Research
Background:
- Ductal lavage is a breast cancer research technique.
- Previous challenges included difficult duct cannulation, subject discomfort, and perforation confirmation.
- These issues limited the method's widespread adoption.
Purpose of the Study:
- To improve the feasibility and comfort of ductal lavage.
- To evaluate the efficacy of intranipple lidocaine and imaging in ductal lavage.
- To establish ductal lavage as a reliable research tool.
Main Methods:
- Healthy women underwent ductal lavage with intranipple lidocaine.
- Ductoscopy and high-definition ultrasound were used for imaging and confirmation.
- Pain scores and retention rates were monitored post-procedure.
Main Results:
- Ductoscopy and ultrasound confirmed duct cannulation in 90.9% of attempts.
- Perforations were identified in 6.8% of cases.
- 91% of subjects reported minimal discomfort (0/10 pain) at 2 weeks, with 90% retention at 6 months.
Conclusions:
- Intranipple lidocaine significantly improves duct cannulation and subject comfort.
- Ductoscopy and ultrasound confirm procedure success and safety.
- These enhancements make ductal lavage a more practical and effective research tool for breast cancer biology.

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
