PURPOSE: To determine the prevalence of constipation-related symptoms in individuals with chronic spinal cord injury (SCI), to describe the bowel program as reported by patients and including use of bowel medications and evacuation techniques, and to examine the clinical, functional and pharmacological risks of difficulty with evacuation. PATIENTS AND METHODS: This is a cross-sectional study of all in-patients at least 3 months beyond acute injury, on the West Roxbury/Brockton VAMC SCI Service, during a 10 month period (n = 197). Clinical, functional, and medication data were abstracted from medical and nursing records. Individual interviews were conducted with all available participants (n = 161, 82%) regarding bowel-related symptoms and treatment over the previous 1 month period. The study definition of difficulty with evacuation was spending more than 1 h per episode of bowel evacuation. RESULTS: Forty-one percent of the 161 interview responders spent more than 1 h on bowel evacuation, 50% reported abdominal distension and 38% reported abdominal pain, 27% reported headaches or sweats relieved by having a bowel movement, and 33% reported fecal incontinence at least once a month. The bisacodyl suppository was the most commonly used laxative agent, while docusate was the most popular oral agent. Subjects with difficulty with evacuation (n = 66) were compared with those who spent less than 1 h on evacuation (n = 95). Factors associated with difficulty with evacuation were tetraplegia, Frankel grade A/B, laxative use, polypharmacy, previous urinary outlet surgery, and symptoms of abdominal pain and distension. CONCLUSION: Constipation-related symptoms are highly prevalent in individuals with spinal cord injury, despite considerable

BACKGROUND: Although recognition of chronic mesenteric ischemia has increased in recent years, this disorder has continued to present diagnostic and therapeutic challenges. OBJECTIVE: To examine the modern results of surgical revascularization for chronic mesenteric ischemia. DESIGN: Retrospective review. SETTING: University medical center. PATIENTS: The management of 24 consecutive patients (mean +/- SEM age, 58 +/- 3 years; 5 men, 19 women) who were undergoing surgical treatment of chronic mesenteric ischemia between 1986 and 1996 was reviewed. INTERVENTION: Surgical mesenteric revascularization. MAIN OUTCOME MEASURES: Postoperative course, long-term graft patency rate, and long-term symptom-free survival rate. RESULTS: The most frequent presenting symptoms were postprandial abdominal pain (18 patients [75%]) and weight loss (14 patients [58%]). Less specific complaints included nausea and vomiting (8 patients [33%]), diarrhea (7 patients [29%]), and constipation (4 patients [17%]). Atherosclerotic risk factors were common, including tobacco use (20 patients [83%]), coronary artery disease (10 patients [42%]), and hypertension (10 patients [42%]). The cause was identified as atherosclerosis in 21 patients, median arcuate ligament compression in 2 patients who were monozygotic twins, and Takayasu arteritis in 1 patient. Lesions were localized to all 3 major visceral vessels (celiac artery, superior mesenteric artery [SMA], and inferior mesenteric artery) in 8 patients, celiac artery and SMA in 13, SMA alone in 2, and SMA and inferior mesenteric artery in 1. Seventeen patients underwent antegrade reconstructions from the supraceliac aorta to the SMA and/or celiac artery; 7 patients underwent revascularization by use of a retrograde bypass that originated fro

To evaluate colonic motility in patients with myelomeningocele, the transit time of radiopaque markers was studied in 22 patients with myelomeningocele and 22 age and sex matched controls. Mean colonic transit time was significantly longer in patients than in controls (103.2 +/- 49 h versus 23.3 +/- 13 h; P < 10(-7). Thirteen of 22 patients with myelomeningocele were severely constipated. Six patients had constipation secondary to delayed colonic transit, particularly in the left colon, and seven had increased rectosigmoid transit. The clinical questionnaire and particularly the frequency of bowel movements did not predict colonic transit. Among 13 patients with increased colonic transit, eight had more than five bowel movements per week and, thus, six of them did not use laxatives or enemas, despite the presence of faecal incontinence. There was no relationship between colonic transit time and the level of the spinal lesion or patient mobility in patients with myelomeningocele. Rectoanal dyssynergia was found in 14 of the 22 patients, but equally often in patients with delayed rectosigmoid transit (4/7) as in the other patients (10/15) (P = ns). Uninhibited detrusor contractions were observed more often in patients with increased colonic transit time than in others (8/12 versus 1/8, P = 0.05). In the absence of a correlation between colonic transit time, clinical symptoms, anorectal motility, level of spinal lesion, patient mobility, evaluation of colonic transit of radiopaque markers should be assessed routinely in all patients with myelomeningocele to plan the most appropriate treatment, mainly in case of unhibited detrusor contractions.
