Objective: The true rate of new-onset diabetes (NODM) after distal pancreatectomy (DP) is not known. This systematic review was carried out to obtain exact percentages regarding the incidence of NODM after DP for different indications.

Background: Distal pancreatectomy is the standard procedure for removal of benign or (potentially) malignant lesions from the pancreatic body or tail and increasingly used for removal of often benign lesions. It is associated with low mortality rates, though postoperative diabetes remains a serious problem.

Methods: Embase, PubMed, Medline, Web of Science, the Cochrane Library, and Google Scholar were searched for articles reporting incidence of NODM after DP. Methodological quality of the included studies was assessed by means of the Newcastle-Ottawa scale for cohort studies and the Moga scale for case series. Mean weighted overall percentages of NODM after DP for different indications were calculated with 95% confidence intervals (CI) and corresponding P values.

Results: Twenty-six studies were included, comprising 1.731 patients undergoing DP. The average cumulative incidence of NODM after DP performed for chronic pancreatitis was 39% and for benign or (potentially) malignant lesions it was 14%. Comparing the proportions of these 2 groups showed a significant difference (95% CI: 0.351–0.434 and 0.110–0.172, respectively, P < 0.000). The average percentage of insulin-dependent diabetes among patients with NODM after DP was 77%.

Conclusions: This review is the largest of its kind to assess the cumulative incidence of NODM after DP and shows that NODM is a frequently occurring complication, with incidence depending on the preexisting disease and follow-up time. Because NODM can affect quality of life, patients undergoing DP should be preoperatively provided with this information as specific as possible.

New-onset diabetes (NODM) after distal pancreatectomy (DP) remains a serious problem. This systematic review was carried out to obtain exact percentages of NODM. Incidences of NODM after DP performed for chronic pancreatitis and for neoplasms were 39% and 14%, respectively. Patients undergoing DP should be preoperatively provided with this information.
