Robotic Surgery for Sigmoid Colon Cancer in a Patient With Severe Obesity and Protocol Proposal of Preoperative Weight Reduction Program.
Article in Cureus, 2025. 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
Surgical procedures in patients with severe obesity are associated with an increased risk of complications. Preoperative weight reduction is recommended. We report a case of robotic-assisted sigmoidectomy in a patient with severe obesity (obesity class III: WHO classification) and sigmoid colon cancer after preoperative management based on the previously reported protocol. A 47-year-old man was referred from a private clinic because of an occult fecal blood test during a routine annual check-up. The colonoscopy with pathological examination and contrast-enhanced computed tomography (CE-CT) revealed stage cT3N1bM0 sigmoid colon cancer. Since he was allowed to wait up to six weeks before colon cancer surgery to avoid intraoperative and postoperative complications, we organized the multidisciplinary team for a preoperative multidisciplinary weight reduction program (WRP) based on corrected body weight (cBW), adding physical therapy, smoking and alcohol cessation counseling, sleep apnea screening, and continuous positive airway pressure (CPAP) therapy. He successfully reduced the BW from 122 to 112 kg and underwent robotic surgery for sigmoid colon cancer with a minimal blood loss of 22 mL. Based on our current experience, we propose preoperative WRP using a concept of cBW for super-obese surgical patients whose BMI is above 40 kg/m
