Randomized Controlled Trial Clinical Trial
Effect of transcutaneous electrical nerve stimulation for pain relief on patients undergoing hemorrhoidectomy: prospective, randomized, controlled trial.
Posthemorrhoidectomy pain control remains a challenging problem. Transcutaneous electrical nerve stimulation is known to be effective in the treatment of many diseases. Our aim was to investigate the effect of transcutaneous electrical nerve stimulation on pain relief in patients undergoing hemorrhoidectomy. ⋯ Transcutaneous electrical nerve stimulation is effective for pain relief in patients receiving hemorrhoidectomy. Its efficacy and safety could assist outpatient pain management after hemorrhoidectomy.

Randomized Controlled Trial Clinical Trial
Is bowel confinement necessary after anorectal reconstructive surgery? A prospective, randomized, surgeon-blinded trial.
The aim of this study was to assess any differences between the inclusion or omission of medical bowel confinement relative to postoperative morbidity and patient tolerance after anorectal reconstructive surgery. ⋯ The outcome of reconstructive anorectal surgery was not adversely affected by the omission of medical bowel confinement. Moreover, cost savings can be achieved by the omission of routine bowel confinement.

Are postoperative drains necessary with the Limberg flap for treatment of pilonidal sinus?
Different methods for managing pilonidal sinus have been described in the literature. Our purpose was to evaluate the influence of postoperative drainage in Limberg flaps. ⋯ We conclude that Limberg flaps with no drains in place will result in shorter hospital stays without deleteriously affecting the surgical results of wide excision and primary closure with well-vascularized tissue.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized controlled trial of primary fistulotomy with drainage alone for perianal abscesses.
Primary fistulotomy may be advantageous for perianal abscesses because unlike ischiorectal abscesses, fistulas are more commonly found and can be laid open with full preservation of the external anal sphincters. Therefore, a randomized, controlled trial was conducted to compare primary fistulotomy with incision and drainage alone, specifically for perianal abscesses. ⋯ Primary fistulotomy at the time of drainage for perianal abscesses results in fewer persistent fistulas and no added risk of fecal incontinence.

Guided imagery: a significant advance in the care of patients undergoing elective colorectal surgery.
Guided imagery uses the power of thought to influence psychologic and physiologic states. Some studies have shown that guided imagery can decrease anxiety, analgesic requirements, and length of stay for surgical patients. This study was designed to determine whether guided imagery in the perioperative period could improve the outcome of colorectal surgery patients. ⋯ Guided imagery significantly reduces postoperative anxiety, pain, and narcotic requirements of colorectal surgery and increases patient satisfaction. Guided imagery is a simple and low-cost adjunct in the care of patients undergoing elective colorectal surgery.
