Amongst complications arising from spinal cord injury (SCI), chronic gastrointestinal (G-I) problems and bowel dysfunction have not received as much research attention as many other medical and rehabilitation problems, even although their incidence is not negligible. We therefore investigated chronic G-I problems and bowel dysfunction in SCI patients where the degree of these was such that activities of daily living (ADL) were significantly affected and/or long-term medical management was required. Detailed semi-structured individual interviews were conducted with 72 traumatic SCI patients. The history of SCI was longer than 6 months, bowel habits had settled, and neurological recovery was completed. The incidence of chronic G-I problems was very high (62.5%), most were associated with defecation difficulties such as severe constipation, difficult with evacuation, pain associated with defecation, or urgency with incontinence. These problems had an extensive impact on ADL, and in particular, restricted diet (80%), restricted outdoor ambulation (64%) and caused unhappiness with bowel care (62%). Bowel care was performed once per 2.85 +/- 1.96 days and occupied an average of 42.1 +/- 28.7 min. To improve bowel habits, 43% of the patients took oral medication, and 36.1% controlled their diet. The usual methods of bowel care were anal massage (34.7%), unaided self-defecation with or without oral medication and abdominal massage (29.2%), finger enema (18.1%), rectal suppository (15.2%) and in two patients a colostomy tube had been inserted because of rectal cancer and traumatic colorectal injury. These chronic G-I symptoms were vague and very subjective, but significant enough to affect the quality of life. Bowel dysfunction was not related to age, d

OBJECTIVE: The aim of this study was to characterize the clinical and motility findings in 62 patients with systemic sclerosis or related disorders referred for evaluation of upper gastrointestinal (GI) symptoms. METHODS: Methods included retrospective clinical record review and quantitation of esophageal, LES antral, and duodenal motility (3 h fasting, 2 h fed) were compared with results of 10 symptomatic patients with normal gastric emptying. RESULTS: A total of 46 patients had systemic sclerosis, eight mixed connective tissue disease, and eight polymyositis-systemic sclerosis overlap; systemic manifestations were almost invariably present. GI symptoms were: heartburn (77%), nausea/vomiting (58%), dysphagia (61%), diarrhea (53%), constipation (31%), and fecal incontinence (13%). Anatomical studies showed esophageal erosions or GERD (53%), aperistalsis (34%), stricture (29%), and Barrett's metaplasia (16%); megaduodenum, small bowel dilation, or diverticulae (42%); and pneumatosis intestinalis (8%). A total of 36 patients underwent esophageal and 26 esophagogastrointestinal manometry. Postprandial antral motility index was abnormal in 22 of 26; amplitudes and frequency in the antrum (34 +/- 3 mm Hg and 0.6 +/- 0.1/min, respectively) and duodenum (7.3 +/- 0.9 mm Hg and 1.8 +/- 0.5/min) were significantly lower than controls (p < 0.05). CONCLUSION: In patients with GI symptoms associated with systemic sclerosis and related disorders, the amplitude and frequency of intestinal contractions are typically <10 mm Hg and <2/min. Antral amplitude is low (<40 mm Hg) when antral hypomotility is observed.

1. Small bowel dysmotility may be one of the clinical manifestations in Occidental patients with irritable bowel syndrome. Here we studied the characteristics of small bowel motility in Oriental patients with irritable bowel syndrome and identified the factors responsible for disturbed small bowel motility. 2. We enrolled 90 patients with irritable bowel syndrome and 45 healthy controls to the study. The patients with irritable bowel syndrome were further divided according to their predominant bowel habits. Of those, 45 were constipation-predominant and 45 were diarrhoea-predominant. Small bowel transit was measured by the non-invasive hydrogen breath test in the fasting state. 3. The transit times obtained in constipation-predominant and diarrhoea-predominant patients with irritable bowel syndrome and in controls were 108.4+/-34.3, 67. 4+/-19.6 and 85.3+/-37.3 min respectively (P<0.05). Delayed transit characterized constipation-predominant patients with irritable bowel syndrome, whereas accelerated transit was observed in diarrhoea-predominant patients with irritable bowel syndrome. The ages of constipation-predominant and diarrhoea-predominant patients with irritable bowel syndrome and of controls displayed a significant positive correlation with their small bowel transit times (r=0.34, 0.31 and 0.39 respectively; P<0.05) and body mass indexes also demonstrated a positive correlation (r=0.31, 0.41 and 0. 30 respectively; P<0.05). Other demographic characteristics did not influence the small bowel transit times. 4. Accelerated or delayed small intestinal transit is exhibited in Oriental patients with irritable bowel syndrome showing
