Research

Three connected axes of Robotic Colorectal Surgical Intelligence (RCSI).

A unified framework linking what we plan before surgery, what we do during surgery, and what happens to the patient afterward. Built around robotic total mesorectal excision (TME) and left-sided colorectal resection.

1. Planning

Anatomical risk stratification from preoperative imaging. Automated CT-based pelvimetry quantifies the mid-pelvic surgical workspace before the patient enters the operating room.

2. Proficiency

Quantitative assessment of robotic technical skill. Video-based risk-adjusted CUSUM and machine learning models replace conventional case-count thresholds for learning curve evaluation.

3. Technique & Outcomes

Novel intracorporeal anastomotic techniques and their oncologic, functional, and short-term outcomes. The Robotic intracorporeal Single-Stapled Anastomosis (RiSSA) technique reduces stapler firings and bowel manipulation.
