Conservative treatment mainly includes fasting, intravenous nutrition, intravenous antibiotics, growth inhibitors, and cardiac monitoring. Surgical treatment may include endoscopic clamping, one-stage suture, wedge resection, colostomy, etc., depending on the size of the perforation, time of the perforation and general condition of the patient.
