Preoperative proton pump inhibitor therapy and anastomotic leak after esophagectomy-a new perspective.

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
purposeProton pump inhibitors (PPIs) are indispensable in the treatment of gastro-esophageal reflux disease and peptic ulcers or for the prevention of stress ulcers after major abdominal surgery. However, long-term PPI therapy leads to several side effects such as delayed gastric emptying and distinct changes in mucosal histology. Therefore, this retrospective study aims to evaluate the impact of preoperative PPI therapy on the anastomotic leak rate after esophagectomy.
methodsA retrospective, single-center analysis was conducted for all patients treated with esophagectomy and gastric conduit reconstruction between January 2016 and November 2024. Preoperative treatment with PPIs, as well as patient comorbidities, histopathological findings and surgical techniques were noted. Subsequently, a group-wise comparison was carried out for the differences in anastomotic leak rate and postoperative complications in patients with and without preoperative PPI therapy. Finally, a multivariate logistic regression analysis was conducted for the occurrence of anastomotic leak.
resultsA total of 229 patients were included in the study. The group-wise comparison revealed a significantly higher rate of anastomotic leaks and postoperative complications in patients with preoperative PPI therapy compared to those without. The multivariate logistic regression analysis indicated a 2.5-fold increased risk of anastomotic leaks in patients with preoperative PPI therapy compared to patients without.
conclusionPreoperative PPI therapy may represent a modifiable risk factor for the development of anastomotic leaks after esophagectomy. Further prospective, interventional studies are necessary to verify the results.
trial registrationThe study was retrospectively registered in the German clinical trial database (Application number DRKS00035536, Registration date 03.12.2024).
