ABSTRACT
Gallbladder diseases are very common entities with diverse features of presentation at clinical, radiological and pathological settings with variable morbidities and mortalities. It implies an altered hepatobiliary function. A majority of gallbladder diseases involve gallstones, which form about 95% of all gallbladder diseases. The noncalculus disease forms only about 4–5% of the cases. Inflammations of gallbladder, either acute or chronic, are commonly seen in association with calculus gallbladder. Benign neoplasms are very rare compared to malignant neoplasms that are more common but uncommon compared to inflammatory conditions. Gallbladder diseases are very common and it is appropriate to emphasise that knowledge of these diseases is imperative. In the present study of 50 patients an attempt was made to correlate the clinical, radiological and pathological features of gallbladder diseases and to ascertain the sensitivity of ultrasound in the evaluation of gallbladder diseases. The radiological diagnosis in gallbladder diseases had favourable results against the clinical diagnosis and has also been shown to be impressive against the pathological diagnosis. In our study the radiological diagnosis of gallbladder diseases is shown with reference to most of the disease conditions.
ABSTRACT
Background: The objective was to find an association between obesity, plasma cholesterol levels, and chelesterolosis of the gallbladder in patients submitted to elective cholecystectomy for gallstone disease. Patients and methods: A sample of 406 patients studied with total plasma cholesterol levels was submitted to cholecystectomy. According to biopsy results they were divided into two groups, 326 patients without cholesterolosis and 80 patients with cholesterolosis. Results: Cholesterol levels were higher in patients without cholesterolosis (209.4+- 53 vs 181.5 +- 37, p<0.0001). Most patients with cholesterolosis had a body mass index > 25kg/m2 compared to patients without cholesterolosis (59 percent vs 48 percent, p=0.036). A positive correlation between body mass index and hypercholesterolemia in patients with and without cholesterolosis was found. ROC curves analysis showed a positive association between hypercholesterolemia and choletithiasis (OR: 3.831; 95 percent CI: 2.260-5.004: area under ROC curve: 0.670), and negative with cholesterolosis (OR: 0.074; 95 percent CI: 0.026-0.394; area under ROC curve: 0.330). Conclusions: Most obese patients with cholesterolosis had normal values of cholesterol compared to eutrophic patients. Eutrophic patients without cholesterolosis had hypercholesterolemia, more frequently than obese patients. Consequently, obesity and hypercholesterolemia are independent, not related factors associated to the development of gallbladder cholesterolosis and gallstones.
Introducción: El objetivo del presente estudio fue encontrar una asociación entre obesidad, niveles plamáticos de colesterol y colesterolosis vesicular en pacientes operados electivamente por colelitiasis. Pacientes y Métodos: Se estudió una muestra de conveniencia de 406 pacientes consecutivos operados por colelitiasis, en los que se midieron niveles plasmáticos de colesterol. De acuerdo al resultado de la biopsia se dividieron en dos grupos: 326 pacientes sin colesterolosis y 80 pacientes con colesterolosis. Resultados: Los niveles de colesterol fueron mayores en pacientes sin colesterolosis (209,4 +- 53 vs 181,5 +- 37, p < 0,0001). La mayoría de los pacientes con colesterolosis tenía un índice de masa corporal > 325 kg/m2 comparados con los pacientes sin colesterolosis (59 percent vs 48 percent, p = 0,036). Se encontró una correlación positiva entre índice de masa corporal e hipercolesterolemia en pacientes con y sin colesterolosis. El análisis con curvas ROC demostró una asociación positiva de la hipercolesterolemia con colelitiasis (OR: 3,831; 95 por ciento IC: 2,260- 5,004: área bajo la curva: 0,670) y negativa con colesterolosis (OR: 0,074; 95 por ciento IC: 0,026- 0,394; área bajo la curva: 0,330). Conclusiones: La mayoría de los pacientes obesos con colesterolosis tuvieron niveles de colesterol normales comparados con pacientes eutróficos. Los pacientes eutróficos sin colesterolosis tuvieron hipercolesterolemia con mayor frecuencia que los pacientes obesos. Consecuentemente, la obesidad y la hipercolesterolemia son factores independeientes asociados al desarrollo de colelitiasis y colesterolosis vesicular.
