AIMS AND BACKGROUND After sphincter-preserving surgery for rectal cancer and postoperative radiochemotherapy, many patients have unsatisfactory anorectal functional results which are not considered by the most common toxicity scales. The aim of the present study was to retrospectively assess the long-term incidence of impaired anorectal function in rectal cancer patients who underwent anterior ...

PURPOSE Fecal incontinence is a major concern, and its incidence increases with age. Quality of life may decrease due to fecal incontinence after both sphincter-saving surgery and a rectal resection with a permanent stoma. This study investigated quality of life, with regard to fecal incontinency, in elderly patients after rectal-cancer surgery. METHODS All patients who underwent elective rec...

OBJECTIVE To identify risk factors associated with anal sphincter tear during vaginal delivery and to identify opportunities for preventing this cause of fecal incontinence in young women. METHODS We used baseline data from two groups of women who participated in the Childbirth and Pelvic Symptoms (CAPS) study: those women who delivered vaginally, either those with or those without a recogniz...

The purpose of this study was to determine the relation between posturally increased intra-abdominal pressure and lower/upper esophageal sphincter pressure changes in patients with gastroesophageal reflux disease. We used high resolution manometry to measure pressure changes in lower and upper esophageal sphincter during bilateral leg rise. We also examined whether the rate of lower and upper e...

We report a 20-year-old female with generalized, severe, recessive dystrophic epidermolysis bullosa who developed secondary chronic anal fissures. This resulted in anal sphincter spasm and severe, disabling pain. She was treated with five botulinum toxin A injections into the internal anal sphincter over a period of 2 years and gained marked improvement in her symptoms. This case demonstrates t...

OBJECTIVE cavernous hemangioma of the rectosigmoid colon is a rare disease, with no more than 200 cases reported in the literature. The rectosigmoid is the most common site of this disease in the gastrointestinal tract. CASE REPORT we report the case of a 31-year-old male with recurrent episodes of rectal bleeding, who was finally diagnosed of diffuse cavernous hemangioma of the rectum. The t...

Coordination of the bladder detrusor and the external urethral sphincter is a supraspinally controlled reflex that is essential for efficient micturition. This coordination is permanently lost after spinal cord transection but can recover chronically after incomplete spinal cord injury (SCI). As glutamatergic transmission plays a key role in all levels of detrusor-external urethral sphincter co...

OBJECTIVE To evaluate the effect of neuronal nitric oxide synthase on the striated urethral sphincter and the urinary bladder. MATERIALS AND METHODS A coaxial catheter was implanted in the proximal urethra and another one in the bladder of female rats, which were anesthetized with subcutaneous injection of urethane. The urethral pressure with saline continuous infusion and bladder isovolumetr...
