Severe chronic constipation of young women: 'idiopathic slow transit constipation'.

Preston DM, Lennard-Jones JE.

A series of 64 women complaining of severe constipation is described, in each of whom delayed elimination of markers from the colon was demonstrated but a barium enema was normal. All completed a detailed questionnaire and the responses are compared with those obtained in an age-matched series of healthy women with no bowel complaint. In each group 40 women also recorded in a manner suitable for analysis all food eaten over a period of seven days. The patients passed about one stool weekly with the aid of laxatives, and were greatly troubled by abdominal pain, bloating, malaise and nausea, to the extent that the symptoms were a major social disability and many lost time from work. Decreased bowel frequency and other symptoms were often first noticed around the age of puberty and slowly became worse until they were severe by the third decade. In a few, the symptoms began suddenly after an abdominal operation c-accident. Comparison with the control group showed no evidence that the patients had been underweight at any time or that they took less fibre; treatment with a bran supplement did not usually help them. The patients experienced rectal sensation before defaecation less often than the control subjects and they used digital pressure to assist defaecation more frequently. The women with constipation tended to have more painful and irregular menstrual periods, and there was an increased incidence of ovarian cystectomy and hysterectomy. Hesitancy in starting to pass urine was more common, as were some somatic symptoms such as cold hands or blackouts. Attention is drawn to this distinctive combination in young women of slow total gut transit time and a colon of normal width on barium enema, associated with abdominal, anorectal, gynaecological and somatic symptoms, as a disorder which can be disabling and particularly difficult to treat.

[Epidemiology of intestinal functional disorders in an apparently healthy population]

[Article in French]

Bommelaer G, Rouch M, Dapoigny M, Pais D, Loisy P, Gualino M, Tournut R.

The characteristics and the prevalence of functional bowel disorders in the general French population are unknown. Based on an epidemiological inquiry in a random population of 1,200 persons who were not seeking care, residents in our country we established: the prevalence of symptoms suggestive of functional bowel disorders; the epidemiological differences between symptomatic subgroups which included abdominal pain with or without bowel dysfunction, diarrhea and constipation. The amount of cases and the prevalence in each subgroup were: abdominal pain, 165, 13.8 p. 100, painless constipation, 75, 6.3 p. 100, diarrhea, 10, 0.8 p. 100. As a whole, functional bowel disorders occurred in 20 p. 100 of our population. The "irritable bowel syndrome" group defined as abdominal pain and/or diarrhea differ from normal subjects by the following higher frequency of age under 50, subjects in active duty, antecedents of diverticulosis, influence of stress on symptoms, nausea, vomiting, migraines, pyrosis and number of visits to a doctor. However neither the sex-ratio nor professional occupation were relevant. The constipation group differed from normal because of the higher frequency of female sex, antecedents of hiatus hernia, use of laxatives but not because of age nor by the number of associated symptoms. In conclusion, functional bowel disorders occurred in 20 p. 100 of our population; two subgroups were clearly different from an epidemiological point of view, the irritable bowel syndrome (13 p. 100) and constipation (7 p. 100); therefore these two groups deserve a specific physiopathological, psychological and therapeutic approach.

Severe idiopathic constipation is associated with a distinctive abnormality of the colonic myenteric plexus.

Krishnamurthy S, Schuffler MD, Rohrmann CA, Pope CE 2nd.

We analyzed the clinical, radiographic, esophageal manometric, and pathologic features of 26 women with severe, idiopathic constipation. Twenty-four patients were between 19 and 39 yr of age. Stool frequency was once every 5-28 days. On barium enema examination, 9 of 24 patients had colons of increased length and 4 of these 9 patients had colons of increased width (greater than 10 cm). Radionuclide solid-meal gastric-emptying studies were normal in 23 patients tested. Esophageal manometry demonstrated high-amplitude waves in 10 of 22 patients and long-duration waves in 3 of these 10 patients. Rectal biopsy specimens showed normal submucosal neurons in all patients and melanosis coli in 6. Twelve patients underwent subtotal colectomies for constipation. Conventional light microscopy using hematoxylin and eosin serial sections showed (a) melanosis coli in 4 patients; (b) normal smooth muscle in 11; (c) thinning of the circular muscle in 1; and (d) no apparent abnormalities of the myenteric plexus in any. In contrast, silver stains of the myenteric plexus showed (a) quantitatively reduced numbers of argyrophilic neurons in 10 patients; (b) morphologically abnormal argyrophilic neurons in 11; (c) decreased numbers of axons in 11; and (d) increased numbers of variably sized nuclei within ganglia in all 12. A coded analysis of the silver stains of colons from 8 patients with constipation and 19 control cases demonstrated that the pathologic abnormalities of severe idiopathic constipation could be differentiated from controls. Thus, severe idiopathic constipation is associated with a pathologically identifiable abnormality of the myenteric plexus. This abnormality appears different from anything previously described in intestinal pseudoobstruction.
