This paper reviews the role of the levator ani muscle (LAM) in evacuation, sexual performance and pelvic floor disorders. The LAM fixes the vesical neck, anorectal junction and vaginal fornices to the side wall of the pelvis by means of the suspensory sling and hiatal ligament. On contraction it shares in the mechanism of evacuation (urination, defecation).(More)

A simple, safe, and reversible method of contraception was used on 28 male volunteers. The testicles were suspended in the superficial inguinal pouch close to the scrotal neck using 2 procedures--stitch and ball suspension. In the former (15 men), the testicle was suspended by stitches and in the latter (13 men), the same thing was done using ball(More)

Twelve women with urinary stress incontinence (USI) due to pudendal canal syndrome (PCS) were treated by pudendal canal decompression. The investigations comprised determination of the EMG activity of the external urethral sphincter (EUS) as well as the straining urethral reflex latency and pudendal nerve terminal motor latency (PNTML). The EMG of the EUS(More)

The paper studies the action and clinical significance of a reflex termed the ‘cervicocavernosus’ reflex. Twenty-two healthy women (mean age 39.7±10.2 SD years) entered the study. The cervix uteri was stimulated both mechanically and electrically by a needle electrode. The response of the bulbo- and ischiocavernosus muscles was recorded by a needle(More)

Constipation is a collective term with different definitions and manifestations. In the present communication, I hope to shed light on the pathogenesis, investigation, and treatment of these manifestations. The levator ani is the principal muscle of defecation; together with anorectal reflex actions, it conducts the act of defecation. Strainodynia is the(More)

The effect of esophageal distension on the lower esophageal sphincter (LES) in 14 normal volunteers and 6 esophageal achalasia (EA) patients was studied. A balloon-tipped catheter was introduced into the LES and a second one into the esophagus. The pressure response of LES to balloon distension of the esophagus and pharyngoesophageal sphincter (PES) was(More)

"Strainodynia" is the name I give to the excessive and exhaustive straining that may accompany defecation. Eighty-six patients with strainodynia were studied; the investigations comprised study of the stool character, proctoscopy, colonoscopy, barium enema, intestinal transit rate, EMG, manometry, and rectal biopsy. These patients were classified into 3(More)

Why anorectal pain is relieved by sitting in a warm-water bath was investigated in 18 healthy volunteers and 28 patients with painful anorectal disease (18 patients with fissures and 10 with hemorrhoids). Investigations consisted of measuring rectal and interstitial sphincter temperature, rectal and rectal neck pressures, and electromyographic activity of(More)

The role of the anorectal band in the genesis of hemorrhoids is studied. The anorectal band is a fibroepithelial tube which is a remnant of the anorectal sinus. Seventy-six hemorrhoid patients and 32 controls were studied. Rectal neck pressure recording was done for all subjects. Two biopsies were taken from the lower rectal neck of each individual of the(More)
AIM To investigate the mechanism of action of thermal cutaneous stimulation on the gastric motor inhibition. METHODS The gastric tone of 33 healthy volunteers (20 men, mean age 36.7 +/- 8.4 years) was assessed by a barostat system consisting of a balloon-ended tube connected to a strain gauge and air-injection system. The tube was introduced into the(More)
