BACKGROUND Women with an obstetric anal sphincter injury are concerned about the risk of recurrent obstetric anal sphincter injury in their second pregnancy. Existing studies have failed to clarify whether the recurrence of obstetric anal sphincter injury affects the risk of anal and fecal incontinence at long-term follow-up. OBJECTIVE The objective of the study was to evaluate whether recurr...

An internal receiver coil was used to obtain high resolution transverse and oblique coronal magnetic resonance images of the anal sphincter in five normal volunteers and five patients. The internal sphincter had a high signal intensity on T1 weighted, T2 weighted, and STIR sequences whereas the conjoined longitudinal muscle and external sphincter had a low signal intensity. The internal sphinct...

We have used a classification of ano-rectal anomalies following the concepts of Keith (1908), Stephens (1953a, b), Browne (1955) and Bill and Johnson (1958), as described elsewhere (Nixon, 1961). The low anomalies in which the 'anus' or 'fistula' is below the puborectalis present few serious problems. The main groups are the covered and ectopic anus, and continence is achieved by adequately enl...

AIM To assess the role of three-dimensional endoanal ultrasound (3D-EAUS) for morphological assessment of the anal sphincter of female patients with chronic proctalgia (CP). METHODS In this unmatched case control study, 30 consecutive female patients with CP and 25 normal women (control group) were enrolled. 3D-EAUS was performed in all subjects. Thickness and length of internal anal sphincte...

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...

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...

Anal fissure is one of the most common anorectal problems. Anal fissure is largely associated with high anal sphincter pressures and most treatment options are based on reducing anal pressures. Conservative management, using increased fiber and warm baths, results in healing of approximately half of all anal fissures. In fissures that fail conservative care, various pharmacologic and surgical o...

BACKGROUND Recently interest in idiopathic (neurogenic) faecal incontinence has swung from denervation of the external anal sphincter to the internal sphincter. AIMS To evaluate the effects of vaginal delivery on the internal sphincter. SUBJECTS 1372 mothers were studied antenatally and 1202 were accepted into the study. METHODS Sphincter pressures were measured antenatally, in the early ...

Anorectal manometry was done in 10 men with chronic radiation proctitis and symptoms of urgency, frequency, and occasional incontinence of faeces. They were compared with 10 asymptomatic age and sex-matched controls. The maximum resting anal canal pressure and the physiological sphincter length were significantly lower (p less than 0.01) in the irradiated group. The rectosphincteric reflex was ...
