Total pancreatectomy and islet autotransplantation in chronic pancreatitis: recommendations from PancreasFest

DESCRIPTION

Total pancreatectomy with islet autotransplantation (TPIAT) is a surgical procedure used to treat severe complications of chronic pancreatitis or very high risk of pancreatic cancer while reducing the risk of severe diabetes mellitus. However, clear guidance on indications, contraindications, evaluation, timing, and follow-up are lacking.

METHODS

A working group reviewed the medical, psychological, and surgical options and supporting literature related to TPIAT for a consensus meeting during PancreasFest.

RESULTS

Five major areas requiring clinical evaluation and management were addressed: These included: 1) indications for TPIAT; 2) contraindications for TPIAT; 3) optimal timing of the procedure; 4) need for a multi-disciplinary team and the roles of the members; 5) life-long management issues following TPIAP including diabetes monitoring and nutrition evaluation.

CONCLUSIONS

TPIAT is an effective method of managing the disabling complications of chronic pancreatitis and risk of pancreatic cancer in very high risk patients. Careful evaluation and long-term management of candidate patients by qualified multidisciplinary teams is required. Multiple recommendations for further research were also identified.

Clinical characterization of patients developing histologically-proven fibrosing cholestatic hepatitis C post-liver transplantation

AIM

  Fibrosing cholestatic hepatitis C (FCH) post-liver transplantation (LT) is an uncommon disorder with extremely poor outcome. Using stringent histological criteria, we sought to identify cases of FCH to better characterize its incidence, clinical features and outcomes.

METHODS

  From January 1991 to December 2007, 973 LT for hepatitis C virus (HCV) were performed at our center. Using the pathology database, 51 cases with a provisional diagnosis of FCH were identified. FCH was diagnosed histologically by cholestasis accompanied by thin periportal fibrous septa, ductular reaction and mild inflammation.

RESULTS

  FCH was reconfirmed in 24 recipients; seven had concurrent biliary problems. Twenty-seven cases were excluded; biopsy was unavailable in nine cases, 15 did not meet the histological criteria of FCH and three had missing clinical information. All received deceased donors at a mean age of 64.4 years (15/17 aged >50 years). Mean time from LT to FCH was 7.6 months with 16 of 17 diagnosed within 1 year of LT. At diagnosis, mean viral load was 14.4 million IU/mL, bilirubin 16.2 mg/dL, aspartate aminotransferase 262 IU/mL, alanine aminotransferase 192 IU/mL and alkaline phosphatase 299 IU/mL. All 17 patients died or required re-LT a mean of 7.8 months after the FCH diagnosis.

CONCLUSION

  FCH occurs infrequently and is typified by hyperbilirubinemia, donor age of more than 50 years, extremely high HCV RNA and specific histological changes occurring within the first several months post-LT with extremely poor patient and graft survival. Histology alone is not reliable for the diagnosis of FCH, especially in the setting of recurrent HCV with concurrent biliary problems.
