Delayed Port-Site Hematoma Following Robot-Assisted Hysterectomy Using the Hinotori Surgical Robot System in an Anticoagulated Patient With Cardiovascular Comorbidities: A Case Report.

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
Perioperative management of patients on anticoagulation therapy requires careful balancing of the thromboembolic and bleeding risks. Heparin bridging is considered for high-risk patients; however, it may increase the incidence of postoperative bleeding complications. We report the case of a 74-year-old woman with stage IA endometrial cancer and cardiovascular comorbidities, including atrial fibrillation and mitral stenosis, who was receiving warfarin therapy. She underwent robot-assisted laparoscopic hysterectomy using the Hinotori surgical robot system with heparin bridging. On postoperative day 5, after restarting both heparin and warfarin, the patient developed a 9-cm subcutaneous hematoma at the right lower abdominal port site. Contrast-enhanced computed tomography suggested bleeding from a perforating branch of the inferior epigastric artery. Anticoagulation was interrupted, and local compression achieved hemostasis. After cautious reinitiation of anticoagulation therapy, the patient was discharged on postoperative day 14 without recurrent bleeding. This case highlights the importance of careful interpretation of activated partial thromboplastin time during heparin bridging in patients receiving warfarin, as additive anticoagulant effects may lead to excessive anticoagulation. In addition, preoperative imaging assessment of abdominal wall vasculature and careful port placement are essential to prevent delayed port-site hemorrhage during robot-assisted surgery.
