Endoscopic retrograde appendiceal irrigation for children with recurrent abdominal pain and appendiceal fecaliths: a retrospective cohort study.

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
Background: Recurrent abdominal pain (RAP) in children with appendiceal fecaliths and mesenteric lymphadenitis poses a diagnostic and therapeutic challenge, often mimicking appendicitis. The role of interventional endoscopy in this setting is undefined. Methods: We retrospectively analyzed children with RAP, sonographically confirmed appendiceal fecaliths, and ileocecal lymphadenitis who underwent ultrasound-guided endoscopic retrograde appendiceal irrigation (ERAI) from 2021 to 2023. Technical success, complications, immediate symptom resolution, and follow-up outcomes were assessed. Results: Totally, 73 patients (mean age 8.3 years) who underwent successful ERAI (100% technical success) were included in this study for safety analysis. Three were lost to follow-up, leaving 70 for efficacy analysis. Immediate pain resolution was reported in 98.6% (69/70) of patients with follow-up. Minor complications such as self-limiting bleeding and procedure-related discomfort occurred in 8.2% (6/73) and 9.6% (7/73) of patients, respectively. There were no perforations or major adverse events. During a median follow-up of 15.5 months, the abdominal pain recurrence rate was 18.6%. The sonographic prevalence of mesenteric lymphadenitis decreased significantly from 100% preoperatively to 21.9% postoperatively ( Conclusions: ERAI appears to be a feasible and safe super-minimally invasive procedure for selected children with RAP associated with appendiceal fecaliths and lymphadenitis, and was associated with rapid symptomatic relief and a significant reduction in lymphadenitis.
