R-LAR was performed safely and effectively, using the da Vinci Surgical System. The use of the system resulted in acceptable perioperative outcomes compared to L-LAR.

Total mesorectal excision with pelvic autonomic nerve preservation showed relative safety in preserving sexual and voiding function. The International Prostate Symptom Score and International Index of Erectile Function questionnaires were useful in assessing urinary and sexual function.

IPLR after curative surgery for colorectal carcinoma is rare. Although it is generally associated with poor prognosis, better survival might be achieved through curative resection in selected cases.

Both transrectal ultrasonography and magnetic resonance imaging with endorectal coil exhibited similar accuracy and were superior to conventional computed tomography in preoperative assessment of depth of invasion and adjacent organ invasion. Because transrectal ultrasonography is a safer and more cost-effective modality than magnetic resonance imaging, transrectal ultrasonography is an appropriate method for preoperative staging of rectal cancer. Further efforts will be needed to provide a better staging of lymph node involvement.

Pathologic complete remission showed excellent oncologic outcomes, and the pathologic N stage was the most important factor for oncologic outcomes.

Totally robotic surgery for rectal cancer using the described technique was feasible and safe. This result could facilitate the spread of robotic surgery for rectal cancer and maximize the advantages of robotic surgery.

These data show that insertion of SEMS as a bridge to surgery in the management of left-sided colon cancer obstruction is possibly associated with adverse oncologic outcomes compared with nonobstructing elective surgery, but it is unclear what magnitude of this effect is related to the underlying obstruction rather than to the SEMS.
