After hiatal hernia repair, in order to reduce the tension of the incision in the groin area, relieve pain and promote healing, lying flat with a soft pillow under the knees is the most appropriate position. This position reduces the pressure in the abdominal cavity and avoids compression of the surgical site, thus reducing the risk of postoperative complications.

Flat lying is also good for wound drainage and preventing infection. Maintaining flat lying in the early postoperative period and gradually transitioning to a semi-recumbent position will help the patient's recovery.
