The perioperative results of robotic and laparoscopic surgery for rectal cancer in obese patients: a systematic review and meta-analysis.
Synthesis in World journal of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses 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
backgroundThe incidence of rectal cancer (RC) among obese patients is gradually increasing. Obesity can elevate the risk of RC surgery in numerous aspects. This paper aims to compare the perioperative results of robotic and laparoscopic surgery for RC in obese patients
methodsWe conducted a standardized search of relevant articles using PubMed, Cochrane Library and Web of Science Core Collection in December 2024. All original research articles relevant to our topic were incorporated into the literature screening process, including randomized controlled trials, prospective cohort studies, and retrospective cohort studies. Study selection was subsequently performed according to predefined inclusion and exclusion criteria.
resultsThis study selected five studies, involving 499 patients. Among these patients, 191 underwent robotic surgery, while the remaining 308 underwent laparoscopic surgery. The results showed that for obese patients with RC, robotic rectal cancer surgery (RRCS) is more effective in reducing hospital stay (WMD, -1.67; p = 0.00001), the rate of overall postoperative complications (OR, 0.41, p = 0.02), and the readmission rate (OR, 0.37; p = 0.03) compared to laparoscopic rectal cancer surgery (LRCS), albeit with longer operative times (WMD, 41.38; p = 0.006). No statistically significant differences were observed between the two surgical methods in terms of estimated blood loss, conversion rates, lymph node yield, positive CRM rates, diverting stoma rates, anastomotic leakage rates, urinary retention rates, and reoperation rates.
conclusionsFor obese patients, RRCS may offer certain potential advantages over LRCS, including a shorter hospital stay, lower overall postoperative complication rates, and lower readmission rates. However, it also involves a longer operative time. These findings suggest that RRCS has the potential to be a safer and more beneficial alternative for obese patients with RC.
