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 ...

Gastrointestinal Endoscopy, 1996
Endosonographic examination of anal sphincters is difficult with water-filled balloon systems because they distort the anatomy of the sphincters. A noncompliant system with parallel walls is preferred, such as the plastic hard cone 1.7 cm in outer diameter (Fig. 1) for the 1850 rectal endoprobe of the B&K Medical System, model 3535, with 10 MHz crystal

Surgical Clinics of North America, 1980
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 ...

Seminars in Colon and Rectal Surgery, 2004
Traumatic disruption of the anal sphincters may result from a wide variety of iatrogenic and accidental mechanisms. Because sphincter trauma is often associated with life-threatening concomitant injuries, the general principles of injury prioritization, perineal debridement, and diversion of the fecal stream in cases of associated rectal laceration are

Scandinavian journal of gastroenterology. Supplement, 1984
The anal sphincter has not generally stimulated great scientific interest although anatomical and physiological disorders of this region are common and may be the cause of considerable suffering to the individual affected. Over the last decade there has, however, been an accelerating interest in the function of this important sphincter.

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

The classical description of the external sphincter has been of a group of muscle fibres surrounding the anal canal and continuing with the pelvic floor at the edge, puborectalis portion, of the levator ani muscle. Studies have been made of this region by histological sections and by various methods of direct dissection.

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.

Audit of anal-sphincter repair
Colorectal Disease, 2001Structural damage of the anterior part of the anal sphincter is a major cause of faecal incontinence. Sphincter repair is the standard surgical treatment. This study was designed to analyse the results of anal sphincter repair, to identify possible predictors of outcome and to investigate the presence of bowel symptoms other than leakage at follow up ...

Diseases of the Colon & Rectum, 1998
INTRODUCTION: Artificial anal sphincter has been proposed in severe anal incontinence when local treatment is unsuitable or has failed. The outcome after implantation of this newly developed device has not yet been determined. METHODS: Twenty-four consecutive patients (7 men; median age, 44; standard deviation, 18; range, 14–80 years) implanted since ...
