Postoperative Blood Glucose Spikes Predict Morbidity After Pancreatoduodenectomy.
Observational study in Journal of diabetes research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPancreatoduodenectomy and distal pancreatectomy are standard surgical treatments for pancreatic tumors but are associated with significant postoperative morbidity. A blood glucose spike (BGS), defined as a rapid, transient rise in glucose levels, may impair vascular function and affect recovery. We aimed to characterize postoperative BGS using continuous glucose monitoring and evaluate associated complications.
methodsThis prospective observational study included 46 patients who underwent pancreatoduodenectomy (n = 34) or distal pancreatectomy (n = 12) between December 2017 and January 2023 at two centers. Glucose levels were continuously monitored for up to 14 days postoperatively using continuous glucose monitoring. BGS was defined as a glucose rise of > 7.8 mmol/L (140 mg/dL), followed by a drop to < 7.8 mmol/L within 2 h. Complications were graded using the Clavien-Dindo classification, with Grade ≥ II considered clinically significant. Multivariate logistic regression identified predictors of morbidity.
resultsPatients who underwent pancreatoduodenectomy had lower preoperative albumin levels, prognostic nutritional index values, and more frequent nocturnal BGS (p = 0.009) than did those who underwent distal pancreatectomy. Mean, maximum, and minimum glucose levels did not differ between groups. Postprandial BGS occurred in all patients after distal pancreatectomy. BGS was associated with complications (p < 0.001) and was the strongest predictor of postoperative morbidity (p = 0.023) in those who underwent pancreatoduodenectomy.
conclusionPostoperative BGS is common after pancreatectomy and strongly predicts morbidity after pancreatoduodenectomy. Continuous glucose monitoring-based detection and management of BGS may reduce postoperative complications.
