Impact of peritoneal lavage on intra-abdominal abscess after laparoscopic appendectomy for perforated appendicitis: a propensity score matching analysis.
Article in BMC gastroenterology, 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
objectiveTo investigate the impact of peritoneal lavage on the incidence of intra-abdominal abscess (IAA) after laparoscopic appendectomy (LA) in adults with perforated appendicitis.
methodsClinical data from adult patients intraoperatively diagnosed with perforated appendicitis and undergoing LA at the Affiliated Hospital of Qingdao University between January 2020 and January 2025 were retrospectively analyzed. Patients were divided into a no-peritoneal lavage group and a peritoneal lavage group based on whether peritoneal lavage was performed. A total of 128 patients were included, comprising 91 in the no-peritoneal lavage group and 37 in the peritoneal lavage group. Patient demographics were collected, and propensity score matching (PSM) was employed to compare clinical data between groups.
resultsAfter PSM, patient demographics showed no significant differences, indicating good balance (P > 0.05). There were no statistically significant differences between the two groups regarding operative time, postoperative antibiotic duration, postoperative length of stay(LOS), or postoperative IAA incidence (P > 0.05).
conclusionOur findings indicate that compared to suction alone, peritoneal lavage did not reduce the incidence of postoperative IAA in adults undergoing LA for acute perforated appendicitis. There is no evidence that patients benefit from lavage. Prospective multicenter randomized controlled trials are warranted.
