Increased incidence of biliary sludge and normal gall bladder contractility in patients with high spinal cord injury.

ABSTRACT: BACKGROUND: Patients with spinal cord injury (SCI) have an increased prevalence of gallstones. AIMS: To study prospectively the incidence of gallstones and gall bladder contractility in patients with SCI. PATIENTS AND METHODS: Thirty six consecutive patients with SCI were studied: 18 patients with SCI above thoracic 10 neuronal segment (> T10) and 18 patients with SCI below T10 (< T10). An equal number each of disease controls (multiple fractures) and healthy controls were also studied. All patients and controls underwent serial ultrasonography to detect development of gallstones and ultrasonographic measurement of gall bladder contractility. RESULTS: A significantly higher number (9/18) of patients with SCI > T10 developed biliary sludge compared with patients with SCI < T10 (2/18), disease controls (2/18), and healthy controls (1/18) (p < 0.05). No patient developed gallstones. The gall bladder fasting volume was significantly decreased in patients with SCI > T10 (20.56 ml; 95% confidence intervals (CI) 19.74 to 21.38) compared with that in patients with SCI < T10 (27.33 ml, 95% CI 26.17 to 28.49; p < 0.05), disease controls (27.92 ml, 95% CI 26.69 to 29.15; p < 0.05), and healthy controls (28.35 ml, 95% CI 27.25 to 29.45; p < 0.05). Gall bladder contractility was normal in patients with SCI as shown by normal gall bladder residual volume and emptying time. CONCLUSIONS: Patients with SCI above T10 have an increased incidence of biliary sludge and a decreased gall bladder fasting volume. Gall bladder contractility is, however, normal.

Project description:BackgroundTraumatic spinal cord injury (SCI) is also a combat-related injury that is increasing in modern warfare. The aim of this work is to inform medical experts regarding the different course of bladder cancer in able-bodied patients compared with SCI patients based on the latest medical scientific knowledge, and to present decision-making aids for the assessment of bladder cancer as a late sequela of traumatic SCI.MethodsA study conducted between January 1998 and December 2019 in the BG Trauma Hospital Hamburg formed the basis for the decision-making aids. Urinary bladder cancer was diagnosed in 40 out of 7396 treated outpatient and inpatient SCI patients. General patient information, latency period, age at initial diagnosis, type of bladder management and survival of SCI patients with bladder cancer were collected and analysed. T category, grading and tumour entity in these patients were compared with those in the general population. Relevant bladder cancer risk factors in SCI patients were analysed. Furthermore, relevant published literature was taken into consideration.ResultsInitial diagnosis of urinary bladder cancer in SCI patients occurs at a mean age of 56.4 years (SD ± 10.7 years), i.e., approximately 20 years earlier as compared with the general population. These bladder cancers are significantly more frequently muscle invasive (i.e., T category ≥ T2) and present a higher grade at initial diagnosis. Furthermore, SCI patients show a significantly higher proportion of the more aggressive squamous cell carcinoma than that of the general population in areas not endemic for the tropical disease schistosomiasis. Consequently, the survival time is extremely unfavourable. A very important finding, for practical reasons is that, in the Hamburg study as well as in the literature, urinary bladder cancer is more frequently observed after 10 years or more of SCI. Based on these findings, a matrix was compiled where the various influencing factors, either for or against the recognition of an association between SCI and urinary bladder cancer, were weighted according to their relevance.ConclusionsThe results showed that urinary bladder cancer in SCI patients differs considerably from that in able-bodied patients. The presented algorithm is an important aid in everyday clinical practice for assessing the correlation between SCI and bladder cancer.
