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
backgroundThe root of mesentery dissection is one of the critical maneuvers, especially in borderline resectable pancreatic head cancer. Intra-abdominal chyle leak (CL) including chylous ascites may ensue in up to 10% of patients after pancreatic resections. Globally recognized superior mesenteric artery (SMA) first approaches are invariably performed. The mesenteric dissection through the inferior infracolic approach has been discussed in this study emphasizing its post-operative impact on CL which is the cornerstone of this study.
aimTo assess incidence, risk factors, clinical impact of CL following root of mesentery dissection, and the different treatment modalities.
methodsThis is a retrospective study incorporating the patients who underwent dissection of the root of mesentery with inferior infracolic SMA first approach pancreatoduodenectomy for the ventral body and uncinate mass of pancreas in the Department of Gastrointestinal and General Surgery of Kathmandu Medical College and Teaching Hospital from January 1, 2021 to February 28, 2024. Intraoperative findings and postoperative outcomes were analyzed.
resultsIn three years, ten patients underwent root of mesentery dissection with inferior infracolic SMA first approach pancreatoduodenectomy. The mean age was 67.6 years with a male-to-female ratio of 4:5. CL was seen in four patients. With virtue of CL, Clavien-Dindo grade II or higher morbidity was observed in four patients. Two patients had a hospital stay of more than 20 days with the former having a delayed gastric emptying and the latter with long-term total parenteral nutrition requirement. The mean operative time was 330 minutes. Curative resection was achieved in 100% of the patients. The mean duration of the intensive care unit and hospital stay were 2.55 ± 1.45 days and 15.7 ± 5.32 days, respectively.
conclusionRoot of mesentery dissection with lymphadenectomy and vascular resection correlated with occurrence of CL. After complete curative resection, these were managed with total parenteral nutrition without adversely impacting outcome.
