Proctalgia fugaxa variant of levator ani syndromeis a severe, episodic pain in the regions of the rectum and anus. It most often occurs in the middle of the night  and lasts from seconds to minutes;  pain and aching lasting twenty minutes or longer would likely be diagnosed instead as levator ani syndrome. In a study published in involving patients, the attacks occurred in the daytime 33 per cent as well as at night 33 per cent and the average number of attacks was
High-resolution colonic manometry promises much deeper insight into human colon motor function and their control mechanisms than hitherto possible. One motor pattern in need of full understanding is the simultaneous pressure wave SPWan apparent instantaneous transient pressure development in the entire colon. Our aim was to provide a characterization of this motor pattern, its relationship to other motor patterns and its appearance in response to a meal, balloon distension and bisacodyl in healthy subjects.
Please take this quick survey to tell us about what happens after you publish a paper. PURPOSE: Many data suggest in irritable bowel syndrome a generalized smooth-muscle disorder, but data are scant concerning anal waves in patients with irritable bowel syndrome. The aim of the present study was first to propose a new method of anal pressure-wave analysis and second to apply this method to patients with irritable bowel syndrome.
This paper is intended to complement that of Lim et al. The dependence of the pattern, and therefore the required dimensional parameters of the stage, on the operating pressure is demonstrated and some conclusions are drawn on points requiring operator care.

Author: Walter A. Strauss Journal: Bull. Abstract: We present a survey of certain aspects of the theory of steady water waves with emphasis on the role played by vorticity.
Advances in Applied Electromyography. The electromyogram EMG is a diagnostic tool that measures and records the electrical activity produced by skeletal muscles. The anal sphincter and urethral external sphincter are skeletal muscle in nature.
A fistula is an abnormal connection between two organs. The opening allows stool and gas to leak from the bowel into the vagina. About 0. Rectovaginal fistula can be difficult to talk about.
Most anal fistulas form in reaction to an anal gland that has developed a pus-filled infection abscess. Even if your abscess drains on its own, you have about the same risk for a fistula. Certain conditions that affect your lower digestive tract or anal area may also increase your risk.
PURPOSE: Many data suggest in irritable bowel syndrome a generalized smooth-muscle disorder, but data are scant concerning anal waves in patients with irritable bowel syndrome. The aim of the present study was first to propose a new method of anal pressure-wave analysis and second to apply this method to patients with irritable bowel syndrome. METHODS: Spectral analysis was used in 20 healthy controls and 60 patients with irritable bowel syndrome to investigate anal pressure waves at rest during a standard anorectal test and during a maintained ml anal distention. Using a cluster analysis, three groups of anal waves were defined in cycles per minute : ultra slow waves 0.
