BACKGROUND 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. METHODS 113 patients were assigned to receive either R-LAR (n = 56) or L-LAR (n = 57) between April 2006 and(More)
BACKGROUND The aim of this study was to analyze clinical and anatomical factors affecting the pathologic quality of the resected specimen after total mesorectal excision (TME) for rectal cancer. METHODS A total of 100 patients who underwent TME for mid or low rectal cancer were evaluated prospectively. MRI pelvimetry data (transverse diameter, obstetric(More)
BACKGROUND AND OBJECTIVES Isolated paraaortic lymph-node recurrence (IPLR) after curative surgery for colorectal carcinoma is rare and no previous report has specifically addressed this type of recurrence. We investigated the clinical features of IPLR and analyzed prognostic factors. METHODS Of 2,916 patients who underwent curative surgery for colorectal(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)
BACKGROUND The purpose of this study is to review the clinical outcomes of patients who received extended lymph node dissection for radiologically diagnosed extramesenteric lymph node metastasis. PATIENTS AND METHODS The authors reviewed clinical characteristics, short-term operative outcomes, and long-term oncologic outcomes of 151 patients who had(More)
OBJECTIVE The purpose of this study was to determine the oncologic outcomes and clinical factors affecting survival in patients who underwent neoadjuvant chemoradiotherapy following tumor specific mesorectal excision for locally advanced, fixed rectal cancer. SUMMARY BACKGROUND DATA Neoadjuvant chemoradiation therapy has resulted in significant tumor(More)
BACKGROUND The da Vinci system is a newly developed device for colorectal surgery, therefore experience of its use for rectal cancer surgery is limited and there are no reports describing the use of four robotic arms with this system. The aim of this study is to evaluate the safety and feasibility of the four-arm da Vinci system for total mesorectal(More)
BACKGROUND Robotic surgery for rectal cancer may be a way to overcome the limitations of laparoscopic surgery. However, totally robotic surgery for rectal cancer is still technically challenging. This report describes the technical details and outcomes of totally robotic rectal surgery. METHODS The authors developed a totally robotic surgery technique for(More)
PURPOSE Total mesorectal excision with pelvic autonomic nerve preservation has been reported to be an optimal surgery for rectal cancer. It minimizes local recurrence and sexual and urinary dysfunction. The aim of this study was to assess the safety of total mesorectal excision with pelvic autonomic nerve preservation in terms of voiding and sexual function(More)
BACKGROUND The prognosis of patients even with the same stage of rectal cancer varies widely. We analyzed the capability of perioperative change of serum carcinoembryonic antigen (CEA) level for predicting recurrence and survival in rectal cancer patients. METHODS We reviewed 631 patients who underwent potentially curative resection for stage II or III(More)
