BACKGROUND/PURPOSE: Since the introduction of the robotic surgery (RS), rectal cancer has been regarded as one of the good indications. Several studies have demonstrated the feasibility and the advantage of the RS. From 2012, we started robotic surgery for rectal cancer. This study aimed to clarify the feasibility and the advantage of RS focusing on rectal cancer. MATERIALS/METHODS: A total of 95 colorectal cancer patients undergoing robotic surgery of curative sphincter saving operation in our institute were enrolled. We analyzed the clinical characteristics, types of operation, operation time, conversion rate, amount of bleeding and perioperative complications.RESULTS: We had performed robotic surgery of 66 low anterior resection (LAR) and 21 intersphincteric resection (ISR). All patients received total mesorectal excision or tumor specific mesorectal excision (TMSE). Preoperative neoadjuvant chemoradiotherapy had been added to 24 patients and extended lateral lymphnode dissection completely through robotic assisted were performed in 27 patients. The median amount of blood loss was 10 ml. There was no open conversion and no leakage after operation. Other complications were as follows; subcutaneous emphysema 2 cases, dysuria 3 cases and peripheral neuropathy 2 cases drain hernia 1 case, respectively. CONCLUSIONS: RS for rectal cancer can be performed safely and it may be one of the most suitable targets to achieve minimally invasive surgery by robot. We demonstrate the video of RS especially for the difficult procedures such as lateral node dissection and ISR.
