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)
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)
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. A total of 100 patients who underwent TME for mid or low rectal cancer were evaluated prospectively. MRI pelvimetry data (transverse diameter, obstetric conjugate,(More)
Laparoscopic colorectal resection has become popular. The recently developed da Vinci Surgical System promises to facilitate endoscopic surgery and overcome its disadvantages. This study therefore aimed to compare the short-term results between robotic tumor-specific mesorectal excision (R-TSME) using the da Vinci Surgical System and conventional(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)
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. We reviewed 631 patients who underwent potentially curative resection for stage II or III rectal cancer. Patients(More)
Anastomotic leakage is a major cause of postoperative morbidity and mortality in the treatment of colorectal cancer. The aim of this study was to investigate the modified double-stapling technique (MDST), as an alternative for conventional double-stapling technique (DST), and whether it could reduce the anastomotic leakage rate in laparoscopic anterior(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)
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/AIMS As the treatment of acute malignant obstruction of the left colon, self-expandable metallic stent insertion has been clinically used with good results. The aim of this study is to analyze the outcome of planned operation after stent insertion for obstructive colorectal cancer. METHODOLOGY From 2000 to 2003, among 37 patients treated for(More)
