External Application of Mirabilite to Promote Recovery in Patients After Gastrointestinal Surgery

Participants in this group will receive an external application of 500 grams of Mirabilite (sodium sulfate decahydrate) beginning on postoperative day 1. The Mirabilite will be wrapped in a double layer of gauze and placed on top of the sterile dressing over the patient's abdominal incision, with the gauze bag secured by an abdominal binder. The application will be regularly replaced when it becomes damp and hardened to maintain continuous efficacy.

Participants in this group will receive standard postoperative care without the application of Mirabilite or any alternative topical treatment. Their surgical sites will be kept dry and clean, with regular sterile dressing changes as part of standard care protocols.
