👉 Antrectomy is a surgical procedure that involves removing a small part of the rectum, or at least its outermost lining, to treat conditions such as cancer or inflammation. It's often used in cases where there are signs of cancer, but it can also be used for other reasons if necessary. Antrectomy may involve using an instrument called a钳子或者钳子，将肿瘤或炎症部位夹住。
