Direct assessment of gastrointestinal inflammation and mucosal immunity in children with cystic fibrosis.

Fibrosing colonopathy is a recently described complication of cystic fibrosis, of unknown aetiology but possibly related to treatment with high-dose pancreatic enzyme supplements. We have used a whole gut perfusion technique to study subclinical gut inflammation in cystic fibrosis patients; concentrations of haemoglobin, IgG, albumin, alpha-1-antitrypsin, granulocyte elastase, IL1 beta, and IL8 were measured in whole gut lavage fluid: 23 tests were performed in 17 children with cystic fibrosis (20 elective tests, three lavages to treat distal intestinal obstruction syndrome (DIOS)). None has had fibrosing or haemorrhagic colitis. There were 12 tests in control children with constipation or precolonoscopy. Moderately abnormal results were obtained for many of the parameters studied, in specimens from all the cystic fibrosis children; however there were no significant differences between tests on high-dose and low-dose enzyme supplements of the same brand in the five children who had duplicate tests performed electively. The lavage fluid specimens from two cystic fibrosis children were strikingly abnormal in all tests apart from haemoglobin and alpha-1-antitrypsin. These were two of the three children with DIOS, and were also the only cases in the series taking Nutrizym 22. These data suggest that the majority of cystic fibrosis children, including those on high-dose enzyme supplements, do not have clinically significant colitis, but that there is subclinical mucosal inflammation in a minority (two of 17 in this series), for which DIOS and/or Nutrizym 22 treatment may be risk factors. Alternatively, inflammation and dysmotility in the proximal colon may be directly produced by a drug or other agent, producing a clinical syndrome indistinguishable from DIOS. Tests

PURPOSE: The aim of this study was to review our experience with patients with rectoceles using very selective criteria for operative repair and to critically review our surgical results. METHODS: This is a review of patients selected for rectocele repair between 1989 and 1994. RESULTS: Two hundred seventy-nine patients were evaluated for pelvic outlet symptoms in our clinic. Defecography was performed in 180 patients; rectocele was seen in 143 patients (79 percent; 135 females and 8 males). On physical examination, 132 patients had a palpable rectocele (73 percent). Rectocele repair was recommended for 35 patients (13 percent); 33 (32 females and 1 male) underwent this procedure. Mean age was 55 (range, 16-78) years. Although many patients complained of constipation, incontinence and pelvic pain, in these 33 patients criteria for repair included the sensation of a vaginal mass or bulge that required digital support and/or rectal digitizing for evacuation (58 percent), retention of barium in the rectocele on defecography (55 percent), or a very large rectocele with internal anterior rectal wall prolapse (6 percent). A hysterectomy had been performed previously in 47 percent of women repaired. Rectocele repair was performed by a standard transanal approach in 31 patients and transabdominally in 2 patients. Hospital stay averaged 3.7 (range, 1-8) days. Few postoperative complications occurred; urinary retention was the most common (18 percent). All patients were followed postoperatively, and 26 patients (79 percent) answered a standardized questionnaire. Mean follow-up was 31 (range, 5-64) months. Eighty percent of patients questioned who initially complained of a vaginal mass or bulge reported complete resolution (significant improvement by the sign test, P < 0.5). Sub

Chronic constipation is an extremely common problem in children. Many authors have advocated using anorectal manometric examination during evaluation of chronic childhood constipation and encopresis as a means of developing individualized modes of treatment. PURPOSE: This study was designed to prospectively examine frequency and severity of symptoms of childhood constipation and encopresis and associate these symptoms with anorectal manometric findings. METHODS: Forty-four children with chronic constipation participated in the study. Before performing anorectal manometry, bowel-related symptoms were collected for two consecutive weeks with a computerized voice mail system. Anorectal manometry was performed using a triple lumen catheter attached to a hydraulic manometry infusion system. RESULTS: Frequency of voluntary bowel movements did not correlate with any manometric parameters. Frequency of fecal soiling, age at onset of symptoms, and duration of symptoms were all highly correlated with degree of sphincter spasm during attempted defecation; however, none of these variables correlated with any other manometric parameter. Amount of pain associated with bowel movements correlated with frequency of soiling and was inversely correlated with maximum squeeze pressure but was not correlated with any other manometric parameter. CONCLUSIONS: In children with chronic constipation and encopresis, sphincter spasm demonstrated with anorectal manometry is highly correlated with frequency of fecal soiling, age at onset, and duration of symptoms; however, none of the other commonly measured manometric parameters appear to correlate with symptoms of chronic childhood constipation and encopresis.
