Comparison of laparoscopic percutaneous extraperitoneal closure (LPEC) and open herniotomy (OH) in pediatric inguinal hernia: a retrospective cohort study on operative time and complications.
Article in Pediatric surgery international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLaparoscopic surgery is widely used for pediatric inguinal hernia repair, but evidence from resource-limited settings remains scarce. This study compared outcomes of open herniotomy (OH) and laparoscopic percutaneous extraperitoneal closure (LPEC) in a regional Thai hospital.
methodsWe conducted a retrospective review of children who underwent OH or LPEC between January 2018 and January 2024. A one-to-one propensity score-matched cohort was created based on age and sex. Outcomes included operative time, anesthetic time, and complications. Univariable and multivariable linear regression identified factors influencing operative and anesthetic time.
resultsAmong 358 operations, 118 matched pairs (236 patients) were analyzed. Median operative time was longer for unilateral LPEC (30 vs. 25 min, p < 0.001) but shorter for bilateral cases (35 vs. 45 min, p = 0.027). Anesthetic time was longer in unilateral LPEC (70 vs. 55 min, p < 0.001) with no difference for bilateral repairs. Multivariable analysis showed LPEC added 4.3 min (95% CI: 0.8-7.9) to operative time after adjusting for confounders. Complication (OH 15.0% vs. LPEC 13.5%) and recurrence rates (1.2% vs. 1.1%) were similar. Metachronous contralateral inguinal hernia (MCIH) occurred only in OH (13.4%), whereas CPPV was detected in 38.6% of unilateral LPEC cases (NNT = 9).
conclusionLPEC is safe, prevents MCIH, and should be considered a first-line option when available.
