Laparoscopic vs. open surgery for rectal cancer in patients with obesity: short-term outcomes and relapse-free survival across age groups.
Article in Surgery today, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeTo investigate the efficacy of laparoscopic surgery for rectal cancer in obese and older patients, who are often characterized by a higher prevalence of comorbidities and physical decline.
methodsThis large-scale multicenter retrospective cohort study included 524 patients with a body mass index of 25 or higher who underwent either open or laparoscopic surgery for stage II or III rectal cancer between 2009 and 2013. We assessed the short-term outcomes and relapse-free survival by comparing these surgical modalities. The patients were stratified into 404 non-elderly (< 70 years) and 120 elderly (≥ 70 years) patients.
resultsIn both patient groups, laparoscopic surgery was associated with a significantly reduced blood loss (non-elderly: 41 vs. 545 ml; elderly: 50 vs. 445 ml) and shorter hospital stays (non-elderly: 10 vs. 19 days; elderly: 15 vs. 20 days) than open surgery. The overall complications and relapse-free survival showed no significant differences between the two surgical techniques in either age group. Additionally, the impact of the laparoscopic procedure on the relapse-free survival remained consistent between the age groups.
conclusionLaparoscopic surgery offers short-term benefits for patients with obesity and rectal cancer compared to open surgery, regardless of age, without influencing the long-term prognosis.
