The aim of this study is to compare the short-term results between robotic-assisted low anterior resection (R-LAR), using the da Vinci® Surgical System, and standard laparoscopic low anterior resection (L-LAR) in rectal cancer patients. 113 patients were assigned to receive either R-LAR (n = 56) or L-LAR (n = 57) between April 2006 and September 2007.(More)
OBJECTIVE The objective of this study was to clarify the impact of robotic surgery (RS) in the management of mid and low rectal cancer in comparison with open surgery (OS) and laparoscopic surgery (LS). BACKGROUND The benefits of RS in the treatment of rectal cancer have not yet been clearly described. METHODS Using propensity scores for adjustment of(More)
The true benefits of robotic surgery are controversial, and whether robotic total mesorectal excision (R-TME) can be justified as a standard treatment for rectal cancer patients needs to be clarified. This case-matched study aimed to compare the postoperative complications and short- and long-term outcomes of R-TME and laparoscopic TME (L-TME) for rectal(More)
OBJECTIVE The aim of this study is to evaluate long-term oncologic outcomes of robotic surgery for rectal cancer compared with laparoscopic surgery at a single institution. BACKGROUND Robotic surgery is regarded as a new modality to surpass the technical limitations of conventional surgery. Short-term outcomes of robotic surgery for rectal cancer were(More)
BACKGROUND We compared outcomes in patients with solitary colorectal liver metastases treated by either hepatic resection (HR) or radiofrequency ablation (RFA). METHODS A retrospective analysis from a prospective database was performed on 67 consecutive patients with solitary colorectal liver metastases treated by either HR or RFA. RESULTS Forty-two(More)
PURPOSE The aim of this study was to determine the correlation between tumor volume changes assessed by three-dimensional (3D) magnetic resonance (MR) volumetry and the histopathologic tumor response in rectal cancer patients undergoing preoperative chemoradiation therapy (CRT). METHODS AND MATERIALS A total of 84 patients who underwent preoperative CRT(More)
Laparoscopy offers some evidence of benefit compared to open rectal surgery. Robotic rectal surgery is evolving into an accepted approach. The objective was to analyze and compare laparoscopic and robotic rectal surgery learning curves with respect to operative times and perioperative outcomes for a novice minimally invasive colorectal surgeon. One hundred(More)
The aim of this study was to evaluate the impact of visceral fat obesity (VFO) on early surgical and oncologic outcomes of laparoscopic total mesorectal excision (LTME) for rectal cancer. Between June 2003 and June 2009, a total of 142 patients who had undergone LTME were included. Patients were divided into the obese group (OG) and the non-obese group(More)
Over the past several years, preoperative chemoradiotherapy (CRT) has contributed remarkably to make more sphincter-preserving procedure (SPP) possible for lower rectal cancer. The aim of this study was to compare the outcomes between abdominoperineal resection (APR) and SPP after preoperative CRT in patients with locally advanced lower rectal cancer. A(More)
Robotically assisted colon resection is a new type of surgery for colon cancer. However, the evidence is inadequate for the general adaptation of robotic colon surgery. This study aimed to show the oncologic and perioperative clinical results of robotically assisted anterior resection (R-AR) compared with those of laparoscopically assisted anterior(More)
