Parammary glands are common in women, and are usually smaller in young, unmarried women. They manifest as a bilateral bulge of tissue in the armpits, with swelling and pain during menstruation. In women who have breastfed, they tend to be larger. In the past, treatment was mostly local excision, which left large scars and was often difficult for young women to accept. I was the first in China to apply the minimally invasive removal of the parametrial glands by McMurdo puncture, which basically leaves no scar due to the small incision. Patients are satisfied with the results. This technique requires a high level of skill for the surgical operator, and the condition is also selective. For particularly large parametrial glands after breastfeeding, this minimally invasive surgery is not very suitable, and it is recommended that the timing of the surgery be chosen before pregnancy.
