Typically, minimally invasive gallstone surgery requires the patient to remain fully nude because of the need for sterilized draping. Gallstone surgery is an upper abdominal procedure, and the area of disinfection goes up to the patient’s bilateral nipple line, down to the pubic symphysis, to the posterior axillary line on the right side, and to the mid-axillary line on the left side. Since the lower disinfection area reaches the perineum, it is necessary to remove the full body clothing. However, after sterilization is completed, the patient is given a triple-layered sterile towel sheet, which exposes only the surgical area during the procedure and covers the rest of the area with the sheet. Generally speaking, abdominal surgery is usually performed with the patient completely nude, while other surgeries such as head surgery or foot surgery only expose the upper or lower half of the patient’s body.
