Prophylactic Subcutaneous Drainage After Gynecologic Oncology Midline Laparotomy

The goal of this clinical trial is to learn whether placing a small drain under the skin can help prevent wound problems after gynecologic oncology surgery in adult women with a thick layer of tissue under the skin. The main question it aims to answer is: Does a small drain placed under the skin lower the number of wound complications within 30 days after surgery? Researchers will compare two groups: Participants in one group will have a small closed-suction drain placed under the skin before the skin is closed. Participants in the other group will not have a drain placed under the skin. All participants will have midline abdominal surgery. During surgery, the surgeon will measure the thickness of the tissue under the skin. Participants with a thickness of 2.5 cm or more will be randomly assigned to one of the two groups. In both groups, the tissue under the skin will be closed in
