Pneumatosis Intestinalis (PI) is a rare complication following hematopoietic stem cell transplant (HSCT). We sought to assess the incidence, risk factors, and outcome associated with PI.
We retrospectively reviewed the incidence of PI among 178 patients who underwent allogeneic HSCT between September 1999 and February 2010.
Eighteen of 178 children (10.1%) who received allogeneic HSCT developed PI at a median of 94 days (range, 11-1169) after transplant. All patients presented with either abdominal pain or distention, and half of the patients had free air on radiographs. Patients who developed PI had a significantly higher proportion of acute (83% vs. 44%, P = 0.002) and chronic graft versus host disease (GVHD; 56% vs. 18%, P
We conclude that PI is a common complication associated with treatment of GVHD after HSCT, and patients who develop PI experience higher TRM. Patients who develop PI should be managed medically.
