Transanal Total Mesorectal Excision vs Robotic Total Mesorectal Excision

TME remains standard treatment for rectal cancer. Both Robotic TME and taTME are innovative surgical techniques with potential advantages in low rectal cancer. To date, no clinical studies have directly compared the conversion and complication rates between taTME and RTME in this population. Therefore, the investigators propose to conduct a prospective, randomized, parallel-controlled clinical trial comparing taTME with RTME for low rectal cancer, aiming to provide high-level evidence for surgical decision-making and benefit more patients.

The Percutaneous Interventional Surgery Control System for Pulmonary Nodule Biopsy

This prospective, single-center, non-inferiority, randomized controlled clinical trial aims to evaluate the efficacy and safety of a percutaneous interventional surgical control system in performing percutaneous needle biopsy of pulmonary nodules, compared with conventional manual biopsy. The study will be conducted at Shanghai Chest Hospital and plans to enroll 158 patients who meet the indications for percutaneous transthoracic needle biopsy (PTNB) and have no contraindications. Participants will be randomly assigned to one of two groups: the experimental group will undergo PTNB assisted by the percutaneous interventional surgical control system, while the control group will receive traditional manual PTNB. The primary endpoint is diagnostic yield; secondary endpoints include technical success rate, number of needle adjustments, puncture time, total procedure time, radiation dose, and complication rates.
