Benign pneumatosis intestinalis after bilateral lung transplantation.

This series details two cases of benign pneumatosis intestinalis (PI) in patients post-lung transplant, which were discovered incidentally on routine surveillance chest radiographs during ambulatory clinic visits. Both patients had uneventful post-transplant recovery and were asymptomatic at presentation. The patients were admitted for observation.

Appendicitis: selective use of abdominal CT reduces negative appendectomy rate.

Background: Recent literature supports the use of CT for all patients with right lower quadrant pain to improve diagnostic accuracy and reduce hospital cost. Our current practice at a large teaching hospital is to use CT only for patients whose diagnosis remains in question after a thorough history, physical examination, and focused laboratory assessment. In consideration of a more liberal use of CT for right lower quadrant pain, we reviewed our experience with selective CT and the effect this has had on our practice, paying particular attention to perforation rate and negative appendectomy rate.
