Evaluating Continuous Glucose Monitoring after Total Pancreatectomy with or without islet autotransplatation: A Scoping Systematic Review

Objectives This scoping review aims to provide evidence synthesis of continuous glucose monitoring (CGM) and insulin pump use after undergone total pancreatectomy (TP) with or without islet autotransplantation (TPIAT). Methods The review was conducted adhering to PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) checklist. Results Fifteen studies including 147 patients (adult n = 71/pediatric n = 76) reported on CGM use post-TP (n = 42) and TPIAT (n = 105). Four were randomized controlled trials and 10 observational studies. Six studies evaluated CGM use in the perioperative and 6 in the immediate postoperative period (n = 8) with variable follow-up (14 hours to 20 months). CGM was used as a stand-alone device (8 studies), which allowed assessment of glycemic variability (n=5) and detection of hypoglycemia (n = 1), resulting in lower glucose levels (n = 1). Six studies evaluated insulin pump with CGM with reduction in postoperative mean glucose (n = 4) and hypoglycemic episodes (n = 2). No patient-reported outcome measures (PROMs) or quality of life (QoL) measures were reported. Conclusions CGM can be used following TP for glucose monitoring and/or linked with insulin pump device in the perioperative period with improved glycemic control. However, the data are limited by short follow-up and lack of PROMs and QoL measures.
