The purpose of this study was to correlate the in vivo endoanal MRI findings of the anal sphincter with the cross-sectional anatomy and histology. Fourteen patients with rectal tumours were examined with a rigid endoanal MR coil before undergoing abdominoperineal resection. In addition, 12 cadavers were used to obtain cross-sectional anatomical sections. The images were correlated with the hist...

More than 85% of women in the United Kingdom (UK) sustain some form of perineal trauma during childbirth1. In the majority of instances, only the perineal skin, vaginal epithelium and superficial muscles are involved, and such tears are only rarely associated with serious sequelae. Tears involving the anal sphincter, however, can have long-term impact on a woman’s quality of life. Sultan2 origi...

Ann Laparosc Endosc Surg 2016;1:24 ales.amegroups.com When a rectal cancer is located at less than 5 cm from the anal verge (very low rectal cancer), abdominoperineal resection (APR) was generally performed (1). However, the patient’s quality of life can be compromised by the social and psychological limitations of a permanen...

BACKGROUND The occurrence of obstetric anal sphincter injuries (OASIS) has increased in most high-income countries during the past twenty years. The consequences of these injuries can be devastating for women and have an impact on their daily life and quality of health. The aim of this study was to obtain a deeper understanding of midwives' lived experiences of attending a birth in which the wo...

Distention of the proximal colon may have inhibitory or excitatory effects on the rectum and vice versa. The reflexes between the proximal colon and the rectum have not been well studied due to difficulties in accessing the proximal colon. The aim of this study was to investigate the reflex responses and their mechanisms between the proximal colon and the rectum in consideration of distention-r...

BACKGROUND Fecal incontinence is a common and severely disabling disorder. For patients with severe fecal incontinence, surgery may prove to be the only adequate treatment option. METHODS This study reports on 43 patients that were treated with a prosthetic sphincter system between 2005 and 2009 in three coloproctological centres. MAIN OUTCOME MEASURES complications, anal pressures before a...

AIM The aim of treatment of anal fistula is to remove the track avoiding while ensuring faecal continence. We report the results of a technique that preserves the external anal sphincter in patients with complex anal fistulas. METHOD Between 2006 and 2009, 18 patients underwent surgery for a complex anal fistula using this technique. It involved initial identification and partial laying open ...

OBJECTIVE To assess the role of anal sphincter damage following delivery in the development of anorectal complaints and urinary incontinence, and to identify obstetric factors associated with subsequent fecal incontinence. METHODS The retrospective cohort study with matched controls used a postal questionnaire and analysis of delivery and operation records from all women who underwent primary...

To investigate the reason why, during a mass contraction, the stool moving from the colon to the sigmoid colon stops short of the rectosigmoid junction (RSJ) instead of passing directly to the rectum, and whether the sigmoid colon and RSJ share in the anorectal continent mechanism, 12 mongrel dogs were studied. Under anesthesia, the anorectum was excised, sigmoid colon and RSJ were mobilized an...
