Comparative Study
Combination propofol/ketamine is a safe and efficient anesthetic approach to anorectal surgery.
Concerns persist regarding respiratory complications from combination deep intravenous sedation and local anesthesia for prone position anorectal surgery. We examined the safety and efficacy of this approach by using a propofol-based and ketamine-based technique. ⋯ Combination deep intravenous sedation with local anesthesia based on propofol and ketamine is a safe and effective technique for prone-position anorectal surgery. It results in decreased use of the postanesthesia care unit and earlier hospital discharge, reflecting a more efficient use of hospital resources.

Rectal volume tolerability and anal pressures in patients with fecal incontinence treated with sacral nerve stimulation.
Sacral nerve stimulation has proven to be a promising treatment for fecal incontinence when conventional treatment modalities have failed. There have been several hypotheses concerning the mode of action of sacral nerve stimulation, but the mechanism is still unclear. This study was designed to evaluate the results of rectal volume tolerability, rectal pressure-volume curves, and anal pressures before and six months after permanent sacral nerve stimulation and to investigate the mode of action of sacral nerve stimulation. ⋯ For patients with fecal incontinence successfully treated with sacral nerve stimulation, there was a significant increase in rectal volume tolerability and rectal capacity. A significant increase in anal resting pressure, but not in maximum squeeze pressure, was found. We suggest that sacral nerve stimulation causes neuromodulation at spinal level.

Total mesorectal excision is the gold standard in the performance of an abdominoperineal resection but little has changed in the way the perineal operation is performed. A frequent problem is anterior dissection. The aim of this study was to present the results of abdominoperineal resection using selected partial anterior en bloc resection to reduce recurrence. ⋯ A multimodal management regimen in patients with low rectal cancer, including preoperative radiotherapy and abdominoperineal resection with a high frequency of partial en bloc resection of the vagina or prostate, resulted in excellent local control and survival. In some male patients, excenteration with urinary stoma can be avoided.

Bowel cancer is a major cause of morbidity and death and is a high cost to health care systems. Screening currently offers the best chance of improving outcomes from bowel cancer. When introducing screening, the problems encountered in other cancers need to be avoided to maximize benefits and minimize harms.

Quality of life is an important outcome measure that has to be considered when deciding treatment strategy for rectal cancer. The aim of this study was to find out the impact of surgery-related adverse effects on quality of life. ⋯ Quality of life after rectal cancer surgery is not worse than that of the general population. The major adverse impact of bowel and urogenital dysfunction is on social functioning. These adverse effects need to be discussed with the patient and preoperative function needs to be taken into account when choosing between treatment options. Permanent colostomy is not always the factor that disrupts a person's quality of life most.
