RESUMEN
Fat malabsorption is common after SBT. To identify whether anatomic variant transplants differ in occurrence of exocrine pancreatic insufficiency that could contribute to fat malabsorption, we measured FPE repeatedly in 54 recipients of a SBT, ages 6.2 to 320 months. FPE determination most distant from SBT was 6.1 years. Of the 54, 39% received an isolated intestinal graft (native pancreas only), 48% received an en bloc liver-intestinal-pancreas graft (native and graft pancreas), and 13% received a multivisceral graft (graft pancreas only). Initial FPE was normal (>200 µg/g) in 15 of the 54 at a median of 22 (11-61) days after SBT. Recipients of a liver-intestine-pancreas transplant were more likely to have normal FPE within 30 days after SBT than were isolated intestinal or multivisceral transplant recipients (47%, 19%, and 0%, respectively, P = .049). Of the remaining 39 patients, 34 eventually demonstrated a normal FPE at a median of 168 (31-943) days after SBT. Type of SBT did not influence the likelihood of achieving a normal FPE level or time when it occurred. Five (9%) patients failed to achieve normal FPE, including 3 who died within 2 years after SBT. In conclusion, possessing both graft and native pancreas as in transplantation of an en bloc liver-intestinal-pancreas graft facilitates early normalization of FPE that eventually occurs in most patients irrespective of transplant type. Failure to recover normal pancreatic function may be associated with severe post-transplant complications.
