The acute abdomen

Interventional procedures

Ongoing gastrointestinal bleeding may be treated by embolization using metallic coils, small pieces of spongostan, polyvinyl alcohol and other agents. Patients may also be treated intravenously by an infusion of vasopressin.

A patient with an abscess in the peritoneal cavity is often best treated with a drainage catheter inserted percutaneously under local anaesthesia using ultrasound or CT guidance.

Ileocolic intussusception and volvulus of the sigmoid colon can also be resolved using radiological techniques as described earlier.
