Steroid associated diverticular perforation is a rare, potentially lifethreatening complication of glucocorticosteroid therapy, associated with a high mortality and morbidity rate. Glucocorticosteroid (GCS) use induces both an increased risk for perforation, and a delay in diagnosis, secondary to the mitigated clinical presentation of peritonitis.
Case reportA 55-year-old man, who recently received high dose intravenous GCS therapy (3 x 500 mg of methylprednisolone) for an acute relapse of Multiple Sclerosis, presented himself at the emergency ward, suffering from dyspnea and abdominal discomfort. A chest X-ray demonstrated clear signs of a pneumoperitoneum with air under both diaphragms (Fig. 1A, B). The patient had no history of recent abdominal surgery nor blunt or penetrating trauma. C-reactive protein levels were elevated (67 mg/L, normal values < 5 mg/L) and there was a neutrophilic leukocytosis (16 x 10 3 white blood cells / mm 3 , 76% neutrophils). An abdominal CT scan, performed after intravenous administration of iodinated contrast, confirmed the presence of free intraperitoneal air and demonstrated diverticulosis of the recto-sigmoid with overt signs of diverticulitis and a pericolic abscess collection due to a ruptured diverticulum ( Fig. 2A, B) The patient was treated by emergency Hartmann surgery, confirming the perforated colon and abscess collection. Postoperative recovery and wound healing was without complications, despite the GCS therapy and the
DiscussionAlthough this case demonstrates evident radiological signs of a peridiverticular abscess with perforation, there was a vast radio-clinical discrepancy. Both the etiology of the intestinal perforation and this paucity of symptoms can be explained by the patient's history.GCSs are known to be positively associated with an increased risk of patient returned home 6 days after surgery with planned closure of the colostomy. JBR-BTR, 2011, 94: 348-349. Patients on glucocorticosteroid therapy are at increased risk of gastrointestinal perforation. The associated morbidity and mortality of perforations in this group is increased, compared with normal groups. This difference is due to the delay between onset of clinical symptoms and treatment. In the presence of steroids, gastrointestinal perforation is more difficult to diagnose clinically because signs and symptoms of perforation are masked by the anti-inflammatory effect of the steroids.
