Volumetric gain of the human pancreas after left partial pancreatic resection: A CT-scan based retrospective study. Academic Article uri icon


  • BACKGROUND/OBJECTIVES: Regeneration of the pancreas has been well characterized in animal models. However, there are conflicting data on the regenerative capacity of the human pancreas. The aim of the present study was to assess the regenerative capacity of the human pancreas. METHODS: In a retrospective study, data from patients undergoing left partial pancreatic resection at a single center were eligible for inclusion (n=185). Volumetry was performed based on 5mm CT-scans acquired through a 256-slice CT-scanner using a semi-automated software. RESULTS: Data from 24 patients (15 males/9 females) were included. MeanSD age was 6811 years (range, 40-85 years). Median time between surgery and the 1st postoperative CT was 9 days (range, 0-27 days; IQR, 7-13), 55 days (range, 21-141 days; IQR, 34-105) until the 2nd CT, and 191 days (range, 62-1902; IQR, 156-347) until the 3rd CT. The pancreatic volumes differed significantly between the first and the second postoperative CT scans (median volume 25.6mL and 30.6mL, respectively; p=0.008) and had significantly increased further by the 3rd CT scan (median volume 37.9mL; p=0.001 for comparison with 1st CT scan and p=0.003 for comparison with 2nd CT scan). CONCLUSIONS: The human pancreas shows a measurable and considerable potential of volumetric gain after partial resection. Multidetector-CT based semi-automated volume analysis is a feasible method for follow-up of the volume of the remaining pancreatic parenchyma after partial pancreatectomy. Effects on exocrine and endocrine pancreatic function have to be evaluated in a prospective manner.
