Appendiceal location in Japanese children with acute appendicitis: pelvic predominance and diagnostic and operative implications.
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
purposeAppendiceal location may affect the diagnosis and surgical management of acute appendicitis. However, pediatric-specific data remain limited. This study evaluated appendiceal location in Japanese children with acute appendicitis and examined its clinical implications.
methodsIn total, 105 pediatric patients who underwent laparoscopic or laparoscopic-assisted appendectomy between January 2015 and March 2024 were retrospectively reviewed. Appendiceal location was classified using a modified Wakeley classification based on intraoperative laparoscopic findings. Clinical presentation, ultrasonographic identification rate, and surgical outcomes were compared among groups.
resultsThe pelvic position was the most common appendiceal location (51.4%), followed by the retrocecal position (20.0%). Approximately 87.6% of patients underwent ultrasonography. The retrocecal group had a significantly lower identification rate than the other location groups (61.1% vs. 85.1%, p = 0.041). The retrocecal group had a significantly longer surgical duration than the pelvic group (median: 90 vs. 58 min, p = 0.010). The clinical presentation and postoperative complications did not differ significantly among the groups.
conclusionIn this cohort of Japanese children with acute appendicitis, the pelvic position was the most common appendiceal location. The retrocecal position was associated with lower ultrasonographic identification rates and a longer surgical duration, indicating greater diagnostic and technical challenges.
