Use of Fluid Gelatin in Lumbar Spinal Stenosis Undergoing Unilateral Biportal Endoscopic: A Prospective, Randomized Controlled Trial.
Trial report in Orthopaedic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
objectivesIn patients with lumbar spinal stenosis (LSS) undergoing unilateral biportal endoscopic unilateral laminotomy for bilateral decompression (UBE-ULBD), damage to the epidural venous plexus often leads to bleeding, increasing the risk of surgical complications. Surgiflo Hemostatic Matrix (SHM) is a gelatin extracted from porcine skin, used for intraoperative hemostasis. This study aims to evaluate the effectiveness and safety of using SHM during UBE-ULBD surgery.
methodsFrom October 2023 to July 2024, a total of 96 patients with LSS underwent UBE-ULBD surgery. These 96 patients were randomly divided into two groups: the SHM group (48 patients, using flowable gelatin) and the non-SHM group (48 patients, not using flowable gelatin). The primary outcomes included intraoperative blood loss, postoperative drainage volume, and the 3-min hemostasis success rate. Secondary outcomes included symptomatic postoperative epidural hematoma (SPEH), surgical time, postoperative hospital stay, hospitalization costs, and complications. We used independent sample t-tests to compare continuous data, and chi-square tests or Fisher's exact tests to analyze categorical data.
resultsThe intraoperative blood loss and postoperative drainage volume in the SHM group were significantly less than those in the non-SHM group (p < 0.05), and the 3-min hemostasis success rate in the SHM group was significantly higher than that in the non-SHM group (p < 0.05). There were no statistically significant differences between the two groups regarding SPEH, postoperative hospital stay, hospitalization costs, and complications such as thrombosis formation and allergic reactions. However, the surgical time in the SHM group was significantly shorter than that in the non-SHM group (p < 0.05).
conclusionWhen patients with LSS undergo UBE-ULBD, the use of fluid gelatin can effectively reduce intraoperative and postoperative bleeding without introducing additional complications.
