Abstract
Background and Objective:
Endocrine insufficiency must be considered following distal pancreatectomy (DP), because diabetes mellitus can impose a long-term burden on patients. This systematic review and meta-analysis aimed to identify the incidence and severity of new-onset diabetes mellitus (NODM) after DP for benign and malignant tumors, and other indications.
Methods:
Articles reporting NODM after DP from PubMed, Embase, Cochrane Library, and Google Scholar were analyzed. The quality of the studies was assessed using the Newcastle–Ottawa Scale or MOGA scale. Inverse variance analysis calculated the overall NODM incidence, and 95% confidence intervals (CIs) and P values were determined. Subgroup analyses considered pre-existing pancreatic diseases.
Results:
The quantitative analysis involved 18 articles that described 2356 patients with pancreatic neoplasms or inflammatory lesions. The overall incidence of NODM after DP was 29% (95% CI 25–33). The NODM rates were 23% (95% CI 17–30) and 38% (95% CI 30–45) for patients with pancreatic neoplasms and chronic pancreatitis, respectively. Pre-existing chronic pancreatitis and being male were risks associated with NODM.
Conclusion:
NODM is fairly common after DP. Surgeons and patients should be aware of postoperative treatment-dependent endocrine dysfunction. Larger cohort studies are required to clarify the risk factors for NODM after DP.
