Studies in animals have suggested a neural reflex between the gall bladder and the sphincter of Oddi. The aim of this study was to investigate whether sphincter of Oddi motility is altered by distension of the gall bladder in humans. Sphincter of Oddi motility was recorded intraoperatively in 10 patients undergoing elective cholecystectomy for gall stones. The manometry was performed by a tripl...

Introduction Fetal incontinence due to agenesis or damage of the sphincter apparatus is a major cause of social dilemma in the pediatric, adolescent and adult population. The anal sphincter consists of an internal sphincter which is a smooth muscle complex and is responsible among other factors for the maintenance of resting pressures. The internal sphincter is surrounded by an external sphinct...

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...

incontinence (gas and liquid stools) shortly after proctologic surgery (fistulectomy). She did not report any obstetric trauma. We performed an anal inspection and a digital rectal examination. There were no anatomical defects, but a severe hypotonic anal sphincter was encountered. Since there is a radial-scanning ultrasound endoscope with frontal vision (Pentax EG3630UR) available in our Unit,...

a correlation stud on the subjective criteria versus lower esophageal sphincter pressure in idiopathic achalasia

Stress urinary incontinence (SUI) is a debilitating disorder caused by malfunctioning of the urethral sphincter. Anatomical and histological properties of the sphincter, its innervation and supporting structures are explained in relation to the closing mechanism of the bladder outlet. Urethral sphincter function is discussed from the passive concept of urethral pressure transmission to the 'ham...

HYPOTHESIS Endoanal ultrasonographic results have demonstrated that clinically occult anal sphincter damage during vaginal delivery is common. This may or may not be associated with postpartum fecal incontinence (FI). Bayesian meta-analysis of the literature revealed that at least two thirds of obstetric sphincter disruptions are asymptomatic in the postpartum period. Women with postpartum asym...

the term ultra short is not clearly defined in ultrashort-segment hirschsprung’s disease. the limited extent of the ultrashort-segment hirschsprung’s disease allows for treatment with extended sphincteromyectomy. in anal sphincter achalasia, anal sphincter dilatation under general anesthesia may be sufficient to treat the condition; in cases with persistent constipation, sphincteromyectomy is i...

The interaction of gastrin and secretin, in the regulation of human lower esophageal sphincter competence, was studied in 54 normal subjects. A dose-response curve, for the lower esophageal sphincter, was constructed from the rapid intravenous injections of synthetic gastrin I (amino acid sequence 2-17). This curve was sigmoid shaped and showed a peak response that was 460.0 +/-24.0% (mean +/-2...
