Gastric bezoar after hepatic transplantation.

A gastric bezoar complicated the postoperative course of three children following successful hepatic transplantation. Two patients had evidence of extremely erratic absorption of the cyclosporine (CSA) used for immunosuppression. Gastric bezoars usually occur in patients with gastric dysmotility and/or patients ingesting poorly digestible material. Although several factors may contribute to bezoar formation after hepatic transplantation, a major predisposing factor may be the administration of the large quantities of olive oil required for solubilization of CSA.
