Chinese Surgical Robot Clinical Study on Rectectomy for Rectal Cancer

Comparision of the Outcomes and Learning Curve of Rectectomy for Rectal Cancer Using Diverse Minimally Technologies: Surgical Robot "Micro Hand S", Laparoscope

Central South University in collaboration with Tianjin University developed the first domestically produced Chinese minimally invasive surgical (MIS) robot system which named "Micro Hand S" in 2013. This new MIS robot had been authorized to enter the clinical trial stage by the Ethics Committee of the Third Xiangya Hospital at Central South University. The Micro Hand S robot is safe and feasible in the preliminary study. However, compared with minimally invasive approaches (da Vici, laparoscope), the merits and demrits of rectectomy for rectal cancer are unclear. Therefore, the investigators conduct this retrospective study to focus on this concern.

This group is consisted of 40 cases performed using the Micro Hand S robot by one single surgeon for rectal cancer

This group is consisted of 65 cases performed using the laparoscope by one single surgeon for rectal cancer

It was defined as what type of procedure was pferformed, for example, low anterior, abdominal perineal resection

It was defined as whether the distal and circumferential resection margins was involved the tumor cell under microscope

It was defined as the adverse events after operation and the complications were classfied according to the Clavien-Dindo (C-D) classification

Inclusion Criteria: histologically confirmed rectal cancer; ASA score < 3 Exclusion Criteria: palliative resections, combined resections, distant metastasis, a previous history of abdominal/or pelvic surgery
