Single-port laparoscopy remains a novel technique in the field of colorectal surgery. Several small series have examined its safety for colon resection. ⋯ This represents the largest experience with single-port laparoscopic right hemicolectomy to date. This technique was used with acceptable morbidity and mortality and without compromise of conventional oncologic parameters by colorectal surgeons experienced in minimally invasive technique. These findings support the use of a single-port approach for patients requiring right hemicolectomy.

Permanent colostomy, pelvic dissection, and radiotherapy after abdominoperineal resection can put quality of life and sexual and urinary function at risk; however, there are limited data using validated instruments on patients undergoing abdominoperineal resection regarding these outcome measures. ⋯ Quality of life and sexual function can be impaired after abdominoperineal resection, although the impact of pelvic radiotherapy appears to be limited. Indication and timing of radiotherapy should be based on oncological indications, but quality of life and functional outcomes should be considered when counseling patients.

Multicenter Study Comparative Study
Improved short-term outcomes of laparoscopic versus open resection for colon and rectal cancer in an area health service: a multicenter study.
Evidence demonstrates short-term benefits of laparoscopic surgery for colon cancer. The situation for rectal cancer is less clear. ⋯ Within an area health service, elective laparoscopic resection for colon and rectal cancer had improved short-term outcomes in comparison with open surgery.

Previous reports suggest that patients with rectal cancer undergoing abdominoperineal resection have worse oncologic outcomes in comparison with those undergoing restorative rectal resection. ⋯ Technical factors alone are unlikely to be responsible for the worse outcomes after abdominoperineal resection in comparison with restorative resection. A combination of patient- and tumor-related factors that may have indicated the choice of the procedure also probably contribute to the worse outcomes. Because patients undergoing abdominoperineal resection represent a high risk for poor outcomes, management strategies need to consider all these factors during treatment.

Sacral nerve modulation has been reported as a minimally invasive and effective treatment for constipation refractory to conservative treatment. ⋯ : Despite improvement in Wexner scores, at the latest follow-up sacral nerve modulation was only being used by slightly more than 50% of the patients who started the first phase of treatment. Further studies are needed to reassess the efficacy and sustainability of sacral nerve modulation.
