Postoperative chyle leak after pancreatic surgery: scoping review.
Article in BJS open, 2025. 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
backgroundChyle leak is a significant complication after pancreatic resection, associated with increased morbidity and mortality. Data on its incidence, risk factors, and treatment are inconsistent. Robotic pancreatic resections are increasingly performed and assumed to be associated with fewer complications than open surgery. This study evaluated the incidence, risk factors, and therapeutic strategies for chyle leak after both open and robotic pancreatic surgery.
methodsA scoping literature review was conducted across multiple databases to identify studies that included patients who underwent open or robotic pancreatic resection and experienced chyle leak as defined by the International Study Group on Pancreatic Surgery. The search period extended from database inception until 27 August 2025.
resultsIn all, 58 studies published between 2007 and 2025 (30 039 patients) were included in the analysis. The pooled incidence of chyle leak after pancreatic resection was 8.0%. Procedure-specific pooled incidences of chyle leak were 9.5% after partial pancreatoduodenectomy, 8.4% after pylorus-preserving pancreatoduodenectomy, 6.9% after distal pancreatectomy, 1.7% after enucleation, and 6.2% after total pancreatectomy. In seven comparative studies (6339 patients), the pooled incidence of chyle leak was 10% after robotic pancreatoduodenectomy and 12% after open pancreatoduodenectomy.
conclusionChyle leak is an important complication following pancreatic resection. Despite advances in surgical techniques, the risk remains substantial, with no clinically significant difference in the rate of chyle leak between robotic and open pancreatoduodenectomy resections.
