Background: As the use of a surgical robot allows for improved dexterity and visual field, we successfully conducted transabdominal intersphincteric resection (ISR) and perineal coloanal anastomosis for a very low lying rectal cancer. The aim of this study was to evaluate the technical feasibility of this procedure.

Materials And Methods: Eight patients underwent robotic-assisted transabdominal ISR with coloanal anastomosis for low rectal cancers.

Background: A surgical robot (the da Vinci system) was developed to overcome the disadvantages of laparoscopic surgery, and applications of this system have been widely used. In this study, we present our standardized technique of robotic right colectomy with lymphadenectomy and intracorporeal anastomosis, with an assessment of feasibility in a series of 15 patients.

Methods: All robotic right colectomies with lymphadenectomy were performed by a single surgeon between April 2009 and March 2010.

Purpose: The aim of this study was to evaluate the relationship between the detection of circulating tumor cell molecular markers from localized colorectal cancer and the time-course of a surgical manipulation or surgical modality.

Methods: From January 2010 to June 2010, samples from the peripheral blood and the inferior mesenteric vein were collected from 42 patients with cancer of the sigmoid colon or rectum. Pre-operative, intra-operative (both pre-mobilization and post-mobilization), and post-operative samples were collected.
