Outcomes after Peripancreatic Fluid Drainage in Patients with Simultaneous Pancreas-Kidney Transplantation

To determine the clinical outcomes of patients who underwent image-guided drainage of peripancreatic fluid collections after simultaneous pancreas-kidney (SPK) transplantation.

A retrospective review of all patients who underwent peripancreatic fluid collection drainage after SPK, from January 2000 to August 2017, at a single institution was performed. Patient characteristics, surgical technique, medication regimen, microbial analysis, and clinical outcomes were reviewed. Thirty-one patients requiring a total of 41 drainages were included in this study. The median age was 44 years (range 30-58 years), and median time between SPK and drainage was 28 days (range 8 to 3,401 days). Fisher's exact test, unpaired Student t-tests, and Pearson correlations were used for statistical analysis.

Fever (51%) and abdominal pain (31%) were the most common presenting symptoms. The average amount of fluid drained at the time of drain placement was 97 mL (SD 240 mL). The average time spent with a drain in place was 33 days (SD 31 days). Microorganisms were isolated in the fluid of 22 of 41 drainages (54%), with mixed gastrointestinal flora being the most common. No further intervention was needed in 34 of 41 drainages (82%). However, drainage failed in 5 of 31 patients (16%), requiring surgical intervention with removal of the pancreas transplant.

Percutaneous drainage of peripancreatic fluid collections after SPK transplantation is a safe and effective treatment option.
