Background: Mammary duct fistula is an abnormal tract formed between the wall of a breast duct and the adjacent tissue or skin, typically resulting from a rupture of the duct wall. This condition is characterized by inflammation due to the leakage of fluid from the surrounding breast tissue. Infection of the sinus tract can lead to the infection of adjacent lactiferous ducts or recurrence in the same sinus tract, ultimately resulting in abscess formation and a prolonged healing process. In severe cases, this condition may be accompanied by breast deformity and other complications.
Case Presentation: A patient with a mammary duct fistula from the General Surgery Department of Dongzhimen Hospital, affiliated with the Beijing University of Chinese Medicine, underwent a modified surgical procedure. Post-surgery, the patient’s nipple inversion was fully corrected with no recurrence observed.
Conclusion: The novel modified surgical procedure demonstrates effectiveness in preventing local recurrence, shortening the clinical course, and addressing pathogenic factors such as nipple inversion. This approach has the potential to improve the cure rate of mammary duct fistulas and is worthy of clinical promotion.
