Defaecation and the Anal Sphincters
Clinics in Gastroenterology, 1982SUMMARY The normal functioning of the act of defaecation requires a coordinated response from the anal sphincteric mechanism to permit easy passage of the faecal bolus. An augmentation of the resting activity in the anal sphincters can lead to constipation whereas a decrease in this activity can be associated with defects in anal control.

Fatigability of the External Anal Sphincter in Anal Incontinence
Diseases of the Colon & Rectum, 2004Anal incontinence commonly results from external anal sphincter dysfunction. The muscle is routinely assessed by anorectal physiology studies. Fatigability is not routinely measured but should be an important factor in the maintenance of continence. The fatigue rate index has been developed to address this.

Injury of the sphincter mechanism that is caused by trauma may be repaired if the operation is carried out without prolonged delay and if sufficient residual sphincter remains. Successful surgical reconstruction requires thorough preoperative evaluation, fastidious preoperative preparation, meticulous surgical technique, and vigorous postoperative ...

Obstetric anal sphincter injury
BMJ, 2010#### Summary points Anal sphincter injury during childbirth is a leading cause of anal incontinence. In a study of more than 20 000 consecutive vaginal deliveries, clinically diagnosed obstetric anal sphincter injury occurred in 2.9% of primiparous women and 0.8% of multiparous ones.1 Of women who have sustained such an injury, 60-80% are asymptomatic

Decreased anal sphincter lacerations associated with restrictive episiotomy use
American Journal of Obstetrics and Gynecology, 2005 Objective To determine whether restrictive episiotomy use was associated with decreases in anal sphincter lacerations and the risk of anal sphincter laceration attributable to episiotomy. Study design This was a retrospective database study.

Standards for anal sphincter replacement
Diseases of the Colon & Rectum, 2000Anal sphincter replacement offers a new treatment option for patients with severe refractory fecal incontinence or for those who require abdominoperineal resection for localized malignancy. The purpose of this study was to review the current status of anal sphincter replacement, formulate a consensus statement regarding its current use, and outline ...

Colorectal Neurovasculature and Anal Sphincter
Surgical Clinics of North America, 1988The varied blood supply of the colon and rectum has been described. It may be stated that the efficiency of any surgeon's hand is primarily dependent on the knowledge that guides it. Significant anatomic facts are described herein. An important blood supply to the terminal ileum comes from the generally unknown ileal artery, which, when absent, creates

Neurophysiologic assessment of the anal sphincters
Diseases of the Colon & Rectum, 1991One hundred twenty consecutive patients with either fecal incontinence (60 patients), chronic constipation (41 patients), or idiopathic intractable pelvic pain (19 patients) were prospectively assessed. Patients underwent concentric needle electromyography (EMG), bilateral pudendal nerve terminal motor latency evaluation, anorectal manometry, and ...

Diseases of the Colon & Rectum, 1998
The internal anal sphincter, the smooth muscle component of the anal sphincter complex, has an ambiguous role in maintaining anal continence. Despite its significant contribution to resting anal canal pressures, even total division of the internal anal sphincter in surgery for anal fistulas may fail to compromise continence in otherwise healthy ...

We review the treatment of fecal incontinence, starting with biofeedback to teach awareness and recruitment of residual function. Should that fail, sacral nerve stimulation (SNS) is suggested. After a percutaneous test stimulation, a neurostimulatory device is implanted.
