A two-center study of laparoscopic appendectomy for chronic abdominal pain.
Article in Pediatric surgery international, 2025. 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
backgroundChronic right lower quadrant (RLQ) abdominal pain in pediatric patients with a negative workup poses a diagnostic and therapeutic challenge. The role of laparoscopic appendectomy (LA) in this cohort remains controversial.
methodsPatients ≤ 18 years old who underwent LA for chronic RLQ pain between 2010 and 2021 were reviewed across two academic centers. Clinical data, operative findings, and histopathological results were compared between those with resolved and persistent pain following appendectomy.
results123 patients underwent LA for chronic RLQ pain. Patients were categorized based on resolution (n = 78) or persistence (n = 45) of their pain following LA. Neither median symptom duration (9.3 [IQR: 2.7-18.7] vs. 6.4 [2.9-18.6] months, p=0.75), presenting symptoms, nor incidence of prior abdominal surgery (14.1% vs. 17.8%, p = 0.58) differed between groups. There was a high incidence of psychiatric diagnoses in both groups (21.8% vs. 24.4%, p = 0.74). Histopathologic findings did not differ between responders and non-responders. Concomitant surgeries were performed in 14.1% of responders (6 planned cholecystectomies, 6 incidental pathologies) and 20.0% of non-responders (4 planned cholecystectomies, 7 incidental).
conclusionsLA provided sustained pain relief for a large subset of pediatric patients with chronic RLQ pain, even though no objective findings could distinguish responders from non-responders. These findings underscore the need for additional research to optimize diagnostic and treatment strategies for these difficult patients.
