Role of body position, gender, and age on pelvic floor location and mobility.

The location and mobility of pelvic floor in different body positions and their relation to age and gender was assessed in 117 patients (19 men, 98 women, age range 10-77 years) with chronic nonorganic constipation (defined as less than three bowel movements per week for at least three years) by means of defocography. Eleven females (age range 16-69 years), without gastrointestinal symptoms, affected by noninvasive carcinoma of the cervix represented a control group. Pelvic floor location was measured as the distance in centimeters of the anorectal junction from the pubococcygeal line; pelvic floor mobility was measured during squeezing, straining, and defecation assuming the pelvic location at rest as zero reference. Pelvic floor location and mobility did not differ between controls and constipated patients. In both groups pelvic floor location at rest was significantly higher (P = 0.001) with patients lying down than sitting up, whereas pelvic floor mobility during squeezing was greater with the patients sitting up than lying down (P = 0.003). In both positions, pelvic floor location at rest was significantly lower (P = 0.01) in females than in males. Pelvic floor mobility during squeezing was significantly different between gender. Parity and hysterectomy did not appear to affect pelvic floor location. Data emerging from this study indicate that body position is one of the major determinants of the pelvic floor location.

Rectal sensitivity in chronic constipation.

Rectal sensitivity is often reduced in patients affected by chronic constipation, but it is not known whether this alteration differs according to the severity and the site(s) of the slowing of gastrointestinal transit. Moreover, it is not known whether alteration precedes or follows bowel complaints. In this study, perception of intrarectal distension was evaluated in 28 healthy controls, in 20 patients complaining of constipation and with a normal gastrointestinal transit time (less than 96 hr), and in 44 patients complaining of constipation and with a prolonged gastrointestinal transit time (greater than 96 hr). Within the latter group, perception to intrarectal distension was analyzed in patients with slowing of transit in the rectum only, in the colon only, and in both the rectum and the colon. In a subgroup of 22 patients, rectal sensitivity was evaluated before and after treatment. Rectal sensitivity was found to be reduced significantly in constipated patients; it was more severely reduced in patients with objective evidence of prolonged gastrointestinal transit time and with slow transit in the rectum. Rectal sensitivity improved in patients who responded to treatment and did not vary significantly in nonresponders.

Laxative consumption in chronic nonorganic constipation.

We looked at laxative consumption and its relationship to bowel habits, total gastrointestinal transit time (TGITT), and symptoms in patients with chronic nonorganic constipation. Of the patients, 87.9% used laxative, 30% habitually. Laxative intake increased with age, so that habitual consumption was more frequent in patients with long-standing (greater than 10 years) constipation. Although habitual laxative users had a consistent trend toward lower bowel frequency and prolonged TGITT, no relationship was found among intake and observed bowel frequency, TGITT, or large bowel segmental transit time. Although laxatives induced more satisfactory or less difficult evacuations, they also caused diarrhea and mucus in the stool. Laxative consumption did not bring about any detectable improvement in the abdominal or extraabdominal symptoms usually associated with constipation.

Melanosis of the rectum in patients with chronic constipation.

In patients with constipation the prevalence of melanosis in rectal biopsies was evaluated in an attempt to correlate its occurrence with laxative consumption and intestinal stasis. Melanosis was present in 58 percent of the patients and in none of a control group. Melanosis was present in 73.4 percent of patients consuming anthracene laxatives and in 26.6 percent of those not consuming anthracene laxatives (P less than 0.01). No correlation was found between the occurrence (and grading) of melanosis and pattern of transit through the large bowel, bowel movements, and duration of symptoms. Results of this study seem to indicate that intestinal stasis is not a cause of melanosis of the colon and rectum and confirm that melanosis may well be due only to the consumption of anthracene laxatives; melanosis coli does not appear to be a sensitive marker of impairment of motor function in the "cathartic colon."

[Diagnosis and treatment of chronic constipation].

Constipation is a symptom caused by several different pathogenetic mechanisms; it may be secondary to other diseases or be in itself a disease. All patients should perform investigations deemed to exclude or identify known causes of constipation and, in the presence of megarectum, anorectal manometry to detect ultrashort Hirschsprung's disease. In idiopathic constipation, diagnostic work up should attempt to identify alterations of defecation, with defecography, and of colonic propulsion, with gastrointestinal transit time measurement. Evaluation of large bowel segmental transit time, using radiopaque corpuscolate markers, may discriminate patients according to different modalities of transit. Based on a correct diagnostic evaluation the therapeutical approach can be finalized to well defined subgroups of patients. The treatment comprises several types of therapy which may be used alone or in association in the individual patient: bowel training, high residue diets, physiotherapy, bio-feedback, pharmacological therapy, psychiatric therapy, surgery.
