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
backgroundEnucleation has the advantages of preserving function and avoiding pancreaticoduodenectomy for benign and low-grade malignant neoplasms in the pancreatic head. However, laparoscopic enucleation (LEn) of pancreatic head tumors remains challenging in terms of bleeding control and duct integrity preservation because of the complicated blood supply to the pancreatic head and the adjacent relationships of lesions with the main pancreatic duct (MPD), especially for deep-seated or broad-based lesions. Here, we developed a novel dual-arterial occlusion technique to facilitate LEn of pancreatic head tumors and evaluated its feasibility and safety.
methodsBetween May 2023 and August 2024, we prospectively included patients with deep-seated or broad-based pancreatic head tumors who received LEn via the dual-arterial occlusion technique. The technique was applied by temporary clamping of both the celiac trunk (CT) and superior mesenteric artery (SMA) to achieve inflow control of the pancreaticoduodenal arcade, minimizing intraoperative hemorrhage and optimizing the surgical field during enucleation. The demographic, intraoperative and postoperative data were analyzed.
resultsIn this study, 14 patients underwent laparoscopic pancreatic enucleation via the dual-arterial occlusion technique. The median occlusion time and operative time were 25.0 (interquartile range, IQR 22.8-27.3) min and 200.0 (IQR 172.5-222.5) min, respectively. The median blood loss was 50.0 (IQR 27.5-50.0) mL. No major bleeding, MPD injury or conversion to open surgery occurred. Three patients developed Grade B postoperative pancreatic fistula (POPF) (3/14, 21.4%), and one experienced Grade III complications (1/14, 7.1%). No Grade C POPF or Grade IV/V complications were observed. The 90-day mortality and reoperation rates were zero. No patient experienced endocrine or exocrine insufficiency.
conclusionThis dual-arterial occlusion appears to be a safe and feasible inflow control technique for LEn of deep-seated or broad-based pancreatic head tumors, with minimal intraoperative blood loss and acceptable overall complication rates.
