BACKGROUND: Percutaneous pancreas allograft biopsy is the technique of choice for evaluation of pancreatic allograft rejection or dysfunction. The safety and success rate of the procedure with current surgical techniques is unclear. We report the complications and success rate in 426 consecutive percutaneous pancreas allograft biopsies performed at a single center.
METHODS: One hundred eighty-three patients (50% simultaneous pancreas-kidney transplant, 42% pancreas after kidney transplant, 8% pancreas transplant alone) were biopsied. Biopsies were performed using an 18-gauge automated needle with ultrasound guidance.
RESULTS: Thirty-seven patients had four or more biopsies (maximum, 11). Two hundred fifteen (50%) biopsies were in patients with bladder exocrine drainage, 211 (50%) in patients with enteric exocrine drainage. Of the latter, 33 (16%) were in patients with portal venous drainage. Eighty-eight percent of biopsy specimens were adequate for histologic diagnosis. There were 12 biopsy-related complications (2.8%), including eight episodes of bleeding (1.9%), five of which (1.2%) required surgical intervention and one possible extra-graft exocrine leak. Other complications included inadvertent liver (1), kidney (1), and small bowel (1) biopsy.
CONCLUSIONS: Percutaneous pancreas allograft biopsy has a low rate of complication and a high success rate.
