Exocrine and endocrine functions and pancreatic volume in patients with pancreatic trauma

Abstract

Injury to the pancreas may lead to significant morbidity and mortality. We aim to assess pancreatic endocrine and exocrine functions and evaluated morphological regenerations of pancreas following partial pancreatectomy in patients with pancreatic trauma. The study was performed between June 2016 and December 2017. Endocrine functions were assessed at the time of admission and at 6 months follow-up with 75 g oral glucose tolerance test (OGTT), serum insulin and C-peptide levels and HbA1c estimation and exocrine functions were assessed with fecal elastase test. Pancreatic volumetry was done with imaging scan at 1 month and 6 months post discharge. Twenty patients were studied with a median age of 30 years (range18–48) at the time of injury. All the patients were normoglycemic on admission; only one patient who underwent pancreatic resection developed diabetes mellitus at follow-up. Eight patients (40%) were found to be prediabetic by American Diabetes Association (ADA) criteria. Eleven patients (55%) had pancreatic exocrine insufficiency. Pancreatic volume increment, from the mean pancreatic volume of 48.65 to 54.29 cm3, was noted in patients who underwent partial pancreatectomy. Patients with pancreatic trauma may develop biochemical endocrine and exocrine insufficiencies following pancreatic resection. Pancreatic volume increment requires further research in a larger study.
