The surgical outcomes and educational value of three laparoscopic approaches for pediatric appendectomy performed by surgical residents rotating through pediatric surgery and pediatric surgery fellow training programs: a two-institution retrospective 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
purposeLaparoscopic appendectomy (LA) is the ideal initial laparoscopic procedure for surgical residents, but the comparative educational value of conventional three-port LA (CTPLA), transumbilical laparoscopy-assisted appendectomy (TULAA), and two-site LA (TSLA) remains unclear.
methodsWe retrospectively analyzed 372 pediatric patients who underwent LA at two institutions between 2016 and 2024. The cases were stratified by technique and appendicitis severity (simple, n = 217; complicated, n = 155). The physicians were classified into the junior residents/surgical residents' group (JR/SR group; n = 55) or the pediatric surgery fellow group (PSF group; n = 317).
resultsIn simple appendicitis, TULAA demonstrated a shorter operative time (62.0 min) than TSLA (85.0 min; p < 0.001) and a shorter pneumoperitoneum time than both other approaches (p < 0.001). Similar advantages were observed in patients with complicated appendicitis. The postoperative hospital stay was shorter with TULAA and CTPLA than with TSLA in simple appendicitis (4.0 vs. 5.0days; p < 0.001). The perioperative complication rates were comparable. TULAA operative time was significantly influenced by surgeon experience (JR/SR group: 94.0 vs. PSF group: 59.5 min; p = 0.005), whereas TSLA was experience-independent (p = 0.983).
conclusionTULAA offers optimal operative efficiency for early resident training. The sequential progression from TULAA to CTPLA to TSLA provides a data-driven framework for structured laparoscopic training in pediatric surgery.
