Gallstones in spinal cord injury (SCI): a late medical complication?

STUDY DESIGN: Prospective controlled study. OBJECTIVES: To assess the prevalence of cholelithiasis among chronic spinal spinal cord injured (SCI) male patients of the ACHS (Asociación Chilena de Seguridad). To evaluate statistically the prevalence of cholelithiasis among SCI patients compared to a control group and to the general male Chilean population. To assess the correlation between cholelithiasis in chronic SCI patients and usual risk factors such as age, obesity and diabetes mellitus. To assess the association of cholelithiasis in chronic SCI patients and the duration of the spinal cord injury. SETTING: Rehabilitation Service at the Hospital del Trabajador, in Santiago, Chile. METHODS: One hundred SCI patients followed up at the Hospital del Trabajador on a regular basis were included in the study; one group consisted of 76 subjects rated ASIA A or B and the other group consisted of 24 subjects rated ASIA C and D. They were all male, older than 20 years old (average age: 41,9 and 42,6 respectively), and suffered from a spinal cord injury greater than one year of evolution. The control group (CG) consisted of 100 male volunteers, without both SCI and history of biliary disease, aged 40.3 years old in average. All three groups underwent ultrasonographic imaging evaluation of the gallbladder and the biliary tract between 1998 and 2000. RESULTS: The prevalence of cholelithiasis among the groups was the following: 25% in the SCI patients ASIA A and B (19/76), 25% in the SCI patients ASIA C and D (6/24) and 9% (1/100) in the CG. The statistical analysis showed a value of P=0.0037, thus establishing a significant association between cholelithiasis and SCI, both complete and incomplete. The difference was not statistically significant when correlating the presence of cholelithiasis with the neurological level of the injury--above and below T10 (24,1 and 25%, respectively)--with the duration of the SCI, with age, obesity and diabetes mellitus. CONCLUSIONS: SCI represents a major risk factor for the development of cholelithiasis, and it should be considered a late, secondary complication of a spinal cord injury.

Clinical evaluation and management of neurogenic bowel after spinal cord injury.

OBJECTIVES: To assess the state of the neurological bowel in spinal cord injured (SCI) patients, design and apply a program for the comprehensive management of neurogenic bowel and evaluate outcome. SETTING: Out-patient in a Rehabilitation Service. SUBJECTS: Thirty-eight SCI patients, 12 (32%) with complete lesions of more than 5 years duration. DESIGN: Observational, longitudinal and prospective. Pre and post intervention. METHOD: Pre and post SCI intestinal function was evaluated clinically prior to beginning program. The presence of GI symptoms were studied. Laboratory work-up included colonic transit time (CTT), anorectal manometry and recto-colonoscopy. An intestinal program was designed, in order to achieve an effective and efficient evacuation in a predictable and socially acceptable time, to avoid short and long term complications and eliminate inadequate intestinal evacuation habits. OUTCOME MEASURES: Pre and post SCI difficulty in intestinal evacuation (DIE) was increased (from 2.6% to 26.3%). The most frequent GI symptom was abdominal distention (53%). Colonic inertia was present in 49% of CTT, internal anal sphincter pressure was normal or increased in 77% and rectoanal inhibitory reflex was present in 88%. With the intestinal program, the incidence of DIE was reduced to 8.8%, manual extraction (ME) was reduced from 53% to 37%. Excellent and good results were obtained in 56% of the patients. CONCLUSION: The proposed intestinal program is effective in the rehabilitation of SCI patients with neurogenic bowel. It is essential to initiate these physiological and safe procedures as soon as possible after sustaining the injury; this will lead to better results and to the elimination of inadequate intestinal maneuvering in the future Spinal Cord (2000) 38, 301 - 308.
