Comparative research on efficacy of needle grasper and mobile retractor-assisted laparoscopic high ligation of hernia sac in treatment of pediatric indirect inguinal hernia.

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
Objective: To compare the clinical efficacy of needle grasper and mobile retractor-assisted laparoscopic high ligation of the hernia sac in the treatment of pediatric indirect inguinal hernia. Methodology: A retrospective analysis was conducted on 531 children with unilateral primary indirect inguinal hernia at Hebei Children's Hospital who were admitted from January 2021 to December 2025. These children were divided into the grasper group(n=198) and the retractor group (n=333) according to the main instruments used for dissecting and ligating the neck of hernia sac during the surgery. Specifically, perioperative indicators, levels of inflammatory factors, complications, recurrence rate and other indicators were compared between the two groups. Results: The needle grasper group showed a significantly shorter operation time than the retractor group (27.74±9.60 min vs. 29.94±7.49 min, P=0.004) and the pain score at 24 h postoperatively was lower (3.26±0.67 vs. 3.99±0.80, P<0.001), along with a smaller increase in inflammatory factors such as IL-6 and CRP postoperatively (P<0.05). Additionally, no statistically significant differences were observed in intraoperative blood loss, incidence of early complications, detection rate of contralateral occult hernia and long-term recurrence rate between the two groups (P>0.05). Conclusion: Both needle grasper and mobile retractor-assisted laparoscopic high ligation of the hernia sac are safe and effective in the treatment of pediatric indirect inguinal hernia. However, needle graspers are superior in shortening the operation time and mitigating postoperative pain and inflammatory response, demonstrating better minimally invasive performance.
