Although tacrolimus-based immunosuppression has made intestinal transplantation feasible, the risk of the requisite chronic high-dose treatment has inhibited the widespread use of these procedures. We have examined our 1990-1997 experience to determine whether immunomodulatory strategies to improve outlook could be added to drug treatment. ⋯ These results demonstrate that longterm rehabilitation similar to that with the other kinds of organ allografts is achievable with all three kinds of intestinal transplant procedures, that the morbidity and mortality is still too high for their widespread application, and that the liver is significantly but marginally protective of concomitantly engrafted intestine. Although none of the endpoints were markedly altered by donor leukocyte augmentation (and chimerism) with bone marrow, establishment of the safety of this adjunct procedure opens the way to further immune modulation strategies that can be added to the augmentation protocol.

Necrotizing pancreatitis is a poorly understood process that has been treated by a variety of surgical approaches. Despite advances in operative interventions and critical care, this disease often requires prolonged resource allocation and continues to cause substantial morbidity, with mortality rates ranging from 11% to 40%. We report on our recent series of patients with necrotizing pancreatitis and our experience with the use of an absorbable mesh in a subset of these patients to facilitate their surgical care. ⋯ Necrotizing pancreatitis remains an important challenge in surgical care. It requires prolonged hospitalization, costly resources, and causes substantial morbidity and mortality. Our patients with infected pancreatic necrosis or clinical deterioration underwent open staged necrosectomy and debridement. Those patients requiring repeat laparotomy often had placement of polyglycolic acid mesh. This provided open drainage of the abdominal cavity and simplified further care by allowing easy abdominal access for repeat drainage procedures, often performed in the intensive care unit. These patients had a high rate of fistula formation, which may be decreased by changes in wound care. Polyglycolic acid mesh is a useful adjunct in the surgical care of selected patients with necrotizing pancreatitis.
