Objective: to investigate the clinical features and treatment of islet cell
tumor. Methods: the clinical manifestations, examination methods and treatment
results of 12 cases of islet cell tumor admitted to our hospital from 2014 to 2018 were
retrospectively analyzed. Results: 11 cases of insulinoma and 1 case of malignant non-
functional islet cell tumor were confirmed by surgery and pathology. Tumor location: 1
case of pancreatic head, 3 cases of pancreatic neck, 4 cases of pancreatic body, 4 cases of
pancreatic body and tail junction, 2 cases of pancreatic tail. All 12 patients underwent
surgical treatment, including 5 patients who underwent pancreaticotailectomy and 7
patients who underwent local tumor resection. Postoperatively, the blood glucose of
patients with functional islet cell tumor increased to 5.5-11 mmol/L, and the symptoms
of abdominal pain of patients with non-functional islet cell tumor disappeared. All 12
cases were cured and discharged from hospital without death. Conclusion: islet cell
tumor is mainly insulinoma and nonfunctional islet cell tumor.
