Impact of in-hospital delay on clinical and economic outcomes after laparoscopic appendectomy for acute appendicitis: a single-center 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
Purpose: Optimal timing of appendectomy after hospital arrival remains controversial. Although early surgery has traditionally been recommended, recent evidence suggests short in-hospital delays may not adversely affect outcomes. This study evaluated the impact of hospital arrival-to-operation time on postoperative outcomes and hospital costs in patients undergoing laparoscopic appendectomy. Methods: We conducted a retrospective study of 661 patients who underwent laparoscopic appendectomy. Patients were categorized into 3 groups according to the interval between hospital arrival and operation start: ≤6 hours (group 1), >6 to ≤12 hours (group 2), and >12 hours (group 3). Baseline characteristics, operative outcomes, postoperative complications, recovery parameters, and hospital costs were compared. Multivariable logistic regression was performed to assess the independent association between in-hospital delay and postoperative complications. Results: Baseline demographic and clinical characteristics were comparable among groups, although American Society of Anesthesiologists classification and serum albumin levels differed slightly. The overall 30-day postoperative complication rates were similar (8.5%, 9.5%, and 10.0% in groups 1, 2, and 3, respectively; P = 0.848). Multivariable analysis showed that in-hospital delay was not independently associated with postoperative complications. No significant differences were observed in severe complications, readmission, mortality, time to oral water intake, soft diet initiation, length of hospital stay, or hospital costs (P = 0.529). Conclusion: An in-hospital delay of >12 hours before appendectomy was not associated with increased postoperative complications, prolonged hospitalization, or higher hospital costs. These findings support flexible scheduling of laparoscopic appendectomy while maintaining safe clinical outcomes.
