Carbohydrate metabolism in patients after pancreatoduodenal resection

Introduction . Pancreatic resection is a common surgical treatment option for chronic pancreatic diseases. Diabetes mellitus, which develops as a result of surgical interventions on the pancreas, belongs to a specific type – pancreatogenic. To assess the state of carbohydrate metabolism in patients after surgery in the volume of pancreatoduodenal resection (PDR), a retrospective single-stage single-center study was performed. Aim . Assessment of the state of carbohydrate metabolism in patients after surgery in the volume of PDR. Materials and methods . In Botkin City Clinical Hospital 70 case histories of patients who underwent PDR were selected. The reason for the PDR was pancreatic head cancer (55 people), chronic pancreatitis (7 people), chronic calculous pancreatitis (8 people). Data on age, gender, date of surgery, glycemia levels before and after surgery, as well as C-peptide, insulin, and HbA1c were analyzed. Results . Out of 70 people in the initial group, diabetes mellitus was diagnosed before surgery in 8 people or in 11.5% of the entire sample. Indicators of carbohydrate metabolism did not differ significantly from each other. However, the level of C-peptide decreased in all patients, while in the group of patients with malignant tumors of the pancreas, despite the decrease in C-peptide, the level of fasting glycemia also decreased. Conclusion . If before the operation diabetes mellitus was diagnosed in 11.5% of patients, then after the operation the diagnosis of diabetes mellitus was established in 23.6%. Late detection of diabetes mellitus worsens not only the quality of life of patients, but also the overall prognosis, morbidity, and tolerability of chemotherapy. Obviously, the postoperative monitoring algorithm should include regular monitoring of glycemia, glycated hemoglobin at least once a year with normoglycemia in order to early diagnose carbohydrate metabolism disorders and prescribe therapy.
