Antibiotic stewardship in non-perforated gangrenous appendicitis: outcomes of single-dose versus postoperative therapy in a retrospective cohort study.
Review in Langenbeck's archives of surgery, 2026. 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
purposeNonperforated gangrenous appendicitis (NGA) is a severe inflammatory condition without perforation, and the optimal duration of postoperative antibiotic therapy remains debated. This study aimed to compare outcomes between single-dose antibiotic therapy (SDAT) and postoperative antibiotic therapy (POAT).
methodsThis retrospective study compared outcomes among 242 adult patients diagnosed histopathologically with NGA after laparoscopic appendectomy who received SDAT versus POAT antibiotics. Demographic characteristics, clinical scores, inflammatory biomarkers, antibiotic regimens, and postoperative surgical infectious complications (PSCs) within 30 days were evaluated. To address group non-homogeneity, regression analyses were performed, and propensity score matching (PSM) was applied as a sensitivity analysis.
resultsAmong the cohort, 68.2% received SDAT and 31.8% received POAT. In the unadjusted analysis, SDAT was associated with significantly shorter hospital stays (14 vs. 79 h; p < 0.001), and PSC rates were lower in the SDAT group (3.6% vs. 11.7%; p = 0.022). However, POAT patients had higher baseline severity markers, older age, elevated CRP, and higher ASA and q-SOFA scores. After propensity score matching on these variables, PSC rates were comparable between groups (11.3% vs. 9.7%; OR 0.84, 95% CI 0.27-2.66; p = 0.769), with no significant differences in intra-abdominal abscess or surgical site infection rates.
conclusionsThese findings suggest that SDAT is a sufficient antibiotic strategy for non-perforated gangrenous appendicitis and supports its use as routine practice in line with antibiotic stewardship principles. However, given the retrospective design, causal inference is limited, and prospective multicentre studies are warranted to confirm these findings.
