Extract

  • Acute mechanical intestinal obstruction should be identified and treated immediately. The treatment of imminent strangulation is particularly urgent (see also Acute abdomen in the adult Acute abdomen in the adult1).
  • In paralytic ileus, conservative treatment should be started early enough.
  • Treat pseudo-obstruction of the colon by removing air or with neostigmine + glycopyrronium medication.
  • Adhesive small bowel obstruction is common especially in patients with a history of abdominal surgery.
  • Paralysis of the small intestine and colonic pseudo-obstruction are often associated with surgical treatment or other severe disease.
  • It is essential to identify those at risk of intestinal perforation and requiring immediate treatment.
