Background: Robot-assisted minimally invasive surgery has effectively addressed the challenges faced by traditional minimally invasive surgery. Well-designed preoperative planning is crucial for robot-assisted minimally invasive surgery.
Methods: This paper proposes a preoperative planning method based on a clinical evaluation system. The particle swarm optimisation algorithm and the evaluation indices including accessibility, visibility, operability, and hand-eye coordination are adopted.
Results: The simulation validation and the experimental verification were conducted to compare the pre-operative planning scheme and the clinical scheme, taking the oesophageal hiatal hernia repair as an example. The preoperative planning scheme demonstrated superior accessibility and hand-eye coordination, achieving shorter surgical time and reduced task load.
Conclusion: The proposed preoperative planning method is feasible and effective through simulation and experimentation. This method has potential applications in various surgical robot systems and procedures, which can provide surgical guidance for surgeons in different departments.

The heterogeneity in prognostic survival and treatment response of hepatocellular carcinoma (HCC) limits the accurate assessment of HCC-specific mortality. This study aimed to identify potential HCC subtypes through latent class analysis (LCA) to improve HCC-specific mortality prediction and optimize treatment recommendations. We analyzed data from 7746 HCC patients in the Surveillance, Epidemiology, and End Results (SEER) databases, incorporating demographic and clinicopathological information and applying LCA to identify HCC subtypes.

Cholesteatoma is a progressive and destructive middle ear disease that can lead to severe complications such as hearing loss, bone erosion, and even intracranial infections if left untreated. Accurate preoperative evaluation is crucial for the successful surgical management of this condition. High-Resolution Computed Tomography (HRCT) has become the gold standard in evaluation of extent of cholesteatoma due to its ability to reveal anatomical details of the middle ear.

Difficult airway management in oromaxillofacial tumor surgery poses significant challenges for anesthesiologists. We present two case reports of patients with mandibular malignant tumors and maxillary osteosarcoma who underwent surgery under general anesthesia. Preoperative assessment revealed a mass involving the right mandible, completely covering the inside of the mouth and invading the floor of the mouth in the first case, and a mass in the left maxilla extending to the zygomatic arch and orbital floor in the second case.

Useful techniques have been previously described for the planning of safe transsacral-transiliac screws, but to our knowledge, no straightforward technique has been described for anterior pelvic percutaneous fixation. As this method of anterior ring fixation has demonstrated biomechanical and clinical benefits, we propose a preoperative planning technique for determining the corridor characteristics of the patient's superior pubic ramus/anterior column for fracture fixation with percutaneous intramedullary screws. This technique helps the surgeon assess what diameter of solid or cannulated screw the corridor allows and predict the length of screw needed.

Purpose: To compare the refractive outcomes and visual quality among different types of astigmatism following SMILE and evaluate effective optical zone (EOZ) features, decentration and their potential effects on visual quality.
Methods: This study included 101 left eyes of 101 patients who underwent SMILE. Patients were grouped according to astigmatism types (with-the-rule [WTR], against-the-rule [ATR] and oblique astigmatism) and decentered displacement (major axis > minor axis and major axis < minor axis).
