Open versus robotic retromuscular ventral hernia repair: outcomes of the ORREO prospective randomized controlled trial.
Trial report in Surgical endoscopy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 papers, 1 of them a synthesis that pooled it.
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
backgroundRobotic retromuscular ventral hernia repair (rRMVHR) potentially combines the best features of open and minimally invasive VHR: myofascial release with abdominal wall reconstruction (AWR) with the lower wound morbidity of laparoscopic VHR. Proliferation of this technique has outpaced the data supporting this claim. We report 2-year outcomes of the first randomized controlled trial of oRMVHR vs rRMVHR.
methodsSingle-center randomized control trial of open vs rRMVHR. 100 patients were randomized (50 open, 50 robotic). We included patients > 18 y/o with hernias 7-15 cm with at least one of the following: diabetes, chronic obstructive pulmonary disease (COPD), body mass index (BMI) ≥ 30, or current smokers. Primary outcome was occurrence of a composite outcome of surgical site infection (SSI), non-seroma surgical site occurrence (SSO), readmission, or hernia recurrence. Secondary outcomes were length of stay, any SSI or SSO, SSI/SSOPI, operative time, patient reported quality of life, and cost. Analysis was performed in an intention-to-treat fashion. Study was funded by a grant from Society of American Gastrointestinal and Endoscopic Surgeons.
results90 patients were available for 30-day and 62 for 2-year analysis (rRMVHR = 46 and 32, oRMVHR = 44 and 30). Hernias in the open group were slightly larger (10 vs 8 cm, p = 0.024) and more likely to have prior mesh (36.4 vs 15.2%; p = 0.030), but were similar in length, prior hernia repairs, mesh use, and myofascial release. There was no difference in primary composite outcome between oRMVHR and rRMVHR (20.5 vs 19.6%, p = 1.000). Median length of stay was shorter for rRMVHR (1 vs 2 days; p < 0.001). All patients had significant improvement in quality of life at 1 and 2 years. Other secondary outcomes were similar.
conclusionThere is no difference in a composite outcome including SSI, SSOPI, readmission, and hernia recurrence between open and robotic RMVHR.
