ABSTRACT
Objective To study the relationship among bile components and different gallstone types through comparing and analyzing gallbladder bile contents in patients with different types of gallstones.Methods A retrospective study of 542 consecutive patients with gallstones or gallbladder polyps was conducted.The stone composition type and 14 kinds of bile components from these patients were analyzed.The bile parameters consisted of potassium (K +),sodium (Na+),chlorine (Cl-),calcium (Ca2+),bicarbonate (HCO3-),magnesium (Mg2+),aspartate aminotransferase (AST),glutamyltranspeptidase (GGT),alkaline phosphatase (ALP),total bilirubin (TBIL),total bile acid (TBA),cholesterol (CHO),lactate dehydrogenase (LDH) and pH.Finally,the content of these bile components among the different types of stones and gallbladder polyps were compared.According to the composition determined by Fourier transform infrared spectroscopy (FTIR),the gallstone patients were divided into five groups.Results Compared with other groups,the content of K +,GGT,ALP,TBIL,TBA and CHO in the calcium carbonate stone group were lower (P ＜ 0.05),while the levels of C1-,HCO3-and value of PH were higher (P ＜0.05).Furthermore,CHO content in the cholesterol stone group was higher than other groups (P ＜ 0.05)except for the gallbladder polyp group (P ＞ 0.05).In addition,there was no difference in bile contents among the pigment gallstone group,mixed stone group and polyp group (P ＞ 0.05).Conclusions In gallstone patients,the bile components of patients with calcium carbonate stones is significantly different.The high cholesterol content in bile is the main feature of cholesterol stone patients,and there is no significant difference in bile composition between patients with pigment stones and mixed stones.
ABSTRACT
ObjectiveTo investigate the relationship between intramural gallstones and intraluminal gallstones. MethodsIn this present study, the control study was applied to analysis on the gallstones from 116 cholecystolithiasis patients with intramural gallstones as well as intraluminal gallstones. All the patients were from the general surgery department and accepted gallbladder-preserving cholecystolithotomy during 2009.02-2009.08. Meanwhile, 171 patients with intraluminal gallstones were investigated the clinical traits; and gallstones from them were analyzed with FT-IR and microsopic examination. ResultsThe results showed the coincidence rate of stone type was 97.4％, and it was mainly pigment gallstones and mixed gallstones in 116 cases; the coincident detection rate of clonorchis sinensis eggs was 98.3 ％, and it was much higher in the pigment gallstones and mixed gallstones than that in the cholesterol gallstones. The ratio of pigment gallstones from the 116 patients group was higher than the 171 patients group, and the detection rate of C. sinensis eggs of the two groups had no statistical difference (P＞0.05). ConclusionsThe stone type of intramural gallstones was mainly pigment gallstones and mixed gallstones. Intramural gallstones and intraluminal gallstones were homologous.
