Saline solution vs. stabilized isotonic sodium hypochlorite lavage in complicated appendicitis: a comparative study.
Article in European journal of trauma and emergency surgery : official publication of the European Trauma Society, 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
purposeThere is no clear consensus on whether peritoneal lavage should be used in complicated appendicitis, nor which solution is ideal. This study evaluated the outcomes of two different intraperitoneal lavage solutions in adult patients with complicated appendicitis.
methodsWe conducted a prospective analytical comparative study including adult patients with complicated appendicitis treated by open appendectomy between January 2023 and July 2024. Patients were allocated according to intraoperative availability of lavage solution to either saline solution (SS) lavage or stabilized isotonic sodium hypochlorite solution (SISHS) lavage. Primary outcomes were length of hospital stay, postoperative complications within 30 days, and total direct treatment costs.
resultsA total of 120 patients were included (60 per group). Baseline demographic and clinical characteristics were comparable. Mean hospital stay was significantly shorter in the SISHS group compared with the SS group (1.86 ± 0.60 vs 6.15 ± 5.59 days; p = 0.004). Postoperative complications, including wound infection, seroma, abdominal wall abscess, intra-abdominal abscess, postoperative ileus, pain, and abdominal distension, were less frequent in the SISHS group (all p < 0.05). Reoperations were required in 21 patients in the SS group and in none of the SISHS group. Total direct treatment costs were 42.8% lower in the SISHS group.
conclusionThese findings suggest that SISHS lavage may offer favorable postoperative outcomes, including shorter hospital stays, lower complication rates, and reduced direct treatment costs in adult patients undergoing open appendectomy for complicated appendicitis. Further controlled studies are needed to confirm these findings.
