Gender-affirming robot-assisted sigmoid vaginoplasty: Outcomes and complications from a retrospective review of 12 cases.

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
Gender-affirming surgery significantly improves the quality of life in transfeminine individuals. Among the various techniques available, sigmoid colon vaginoplasty offers both anatomical and functional advantages. However, conventional approaches are associated with high morbidity. Thus, we aimed to evaluate the outcomes of robot-assisted sigmoid vaginoplasty, emphasizing the complications and clinical results. Between July 2021 and March 2023, 12 patients underwent robot-assisted sigmoid vaginoplasty. Preoperative assessments included colonoscopy and abdominal computed tomography. Flap preparation and canal dissection were performed using a da Vinci XI platform. Postoperative management included vacuum-assisted closure dressing, bed rest, and vaginal dilator use. Clinical outcomes, complications, and sexual activity (SA) were retrospectively analyzed. The mean patient age was 27.9 years (95% confidence interval [CI]: 21.8-34.0). The mean total operative time was 544.8 minutes (95% CI: 494.4-595.1). Intraoperative complications were not observed. The mean vaginal length achieved was 14.6 cm (95% CI: 12.9-16.3), with no cases of vaginal stenosis. Positive SA was reported in 75% of the cases. The overall postoperative complication rate was 41.7% (5/12). Complications included ileus (2 cases, Grade II), vaginal prolapse (1 case, Grade IIIa), anastomotic leakage (1 case, Grade IIIb), and colon flap necrosis (1 case, Grade IIIb), all of which were successfully managed. Robot-assisted sigmoid vaginoplasty demonstrated favorable functional and aesthetic outcomes with manageable complications. However, anastomotic leakage and flap necrosis highlight the importance of careful consideration of vascular supply. Further comparative studies are required to evaluate its advantages over peritoneal vaginoplasty.
