Repeated abdominal pain after conservative treatment of intestinal obstruction may be caused by recurrence of intestinal obstruction, intestinal tumors that have not been eradicated and other reasons. 1. Recurrence of intestinal obstruction: if the patient has undergone abdominal surgery, it may cause intestinal adhesion, and obstruction will occur when the adhesion is serious, which can be treated with metronidazole and ceftriaxone under the guidance of doctor’s instruction, but if the cause of adhesion is not eliminated, abdominal pain and abdominal distension may occur repeatedly. 2. Intestinal tumor has not been eradicated: if the intestinal obstruction is caused by intestinal tumor, it can be relieved through conservative treatment in the short term, but the intestinal tumor has not been resected, and the tumor is still in the original position, which will inevitably recur, thus causing obstruction, abdominal pain and other symptoms. Repeated abdominal pain after conservative treatment of intestinal obstruction requires colonoscopy to determine the cause of the disease before treatment. Patients with recurrent abdominal pain after conservative treatment of intestinal obstruction are advised to go to the hospital in time, to clarify the cause and standardize the treatment under the guidance of the doctor.
