Factors influencing the prevalence of gallstones in liver cirrhosis

Risk Factors for Early Recurrence of Gallstones in Patients Undergoing Laparoscopy Combined With Choledochoscopic Lithotomy: A Single-Center Prospective Study

Objective: For patients with gallstones, laparoscopy combined with choledochoscopic lithotomy is a therapeutic surgical option for preservation rather than the removal of the gallbladder. However, postoperative recurrence of gallstones is a key concern for both patients and surgeons. This prospective study was performed to investigate the risk factors for early postoperative recurrence of gallstones.

Methods: The clinical data of 466 patients were collected. Each patient was followed up for up to 2 years. The first follow-up visit occurred 4 months after the operation, and a follow-up visit was carried out every 6 months thereafter. The main goal of each visit was to confirm the presence or absence of gallbladder stones. The factors associated with gallstone recurrence were analyzed by univariate analysis and Cox regression.

Results: In total, 466 eligible patients were included in the study, and 438 patients (180 men and 258 women) completed the 2-year postoperative follow-up. The follow-up rate was 94.0%. Recurrence of gallstones was detected in 5.71% (25/438) of the patients. Univariate analysis revealed five risk factors for the recurrence of gallstones. Multivariate Cox regression analysis showed that multiple gallstones, a gallbladder wall thickness of ≥4 mm, and a family history of gallbladder stones were the three predictive factors for postoperative recurrence of gallstones (P < 0.05).

Conclusion: The overall 2-year recurrence rate of gallstones after the operation was 5.71%. Multiple gallstones, a gallbladder wall thickness of ≥4 mm, and a family history of gallstones were the three risk factors associated with early postoperative recurrence of gallstones.

Frequency of gallstones and mean BMI in decompensated cirrhosis

Introduction

The aim of the study was to determine the frequency of gallstones in patients with decompensated cirrhosis and to know about mean Body mass index (BMI) in patients of decompensated cirrhosis i.e End stage liver disease (ESLD) with and without gallstones.

Methods

it is a cross sectional descriptive study, conducted at the department of Hepato-gastroenterology, Sindh Institute of Urology and Transplantation (SIUT), Karachi from 1^st August 2014 to 28 February 2015. Two hundred patients were enrolled from outpatient clinics of Hepato-gastroenterology that fulfilled the defined selection criteria. Questionnaire was filled for data collection. SPSS version 20.0 was used to analyze data. Mean value of age and BMI was calculated by mean ± S.D. values. Mean ± SD was also calculated for BMI in patients with and without gallstones. Stratification of the age, gender, and liver disease severity were done and chi-Square test was applied. p-values less than 0.05 considered statistically significant.

Results

Two hundred consecutive patients were enrolled among them 112(56%) were male. Mean age was 46.89 ± 11.9, BMI 23.59 ± 4.7 and CTP score was 9.7 ± 1.9. Most of the patient had Child class 'B' cirrhosis 102(51%), most common etiology was found to be Hepatitis C 133 (66.5%), cholelithiasis was found in 59(29.5%), sludge in 36 (18%) and both stone and sludge in 24(12%) of the cases. Advanced liver disease that is, more CTP score and child class 'C' was associated with increased frequency of gall stone formation (p-value = 0.012), and advancing age on age stratification (p-value = 0.024) however no relation was observed with increase BMI, gender, ethnicity, cause or duration of disease in this population.

Conclusion

Gallstone formation is associated with advanced stage of cirrhosis and hepatitis C Virus related CLD, contrary to the established risk factors, no relation of gender or BMI was found in decompensated liver disease.

Cholecystectomy in cirrhotic patients – how safe is it?

Liver cirrhosis is a major health problem worldwide with a prevalence that varies greatly from one geographical area to another. Besides the risk factors common to the general population to develop gallstone disease such as advanced age, female sex or positive family history of gallstones, in patients with liver cirrhosis there are additional risk factors that contribute to the occurrence of gallstones. They are more frequent in patients with a longer duration of the disease and in Child B and C stages. Gallstones disease occurs three times more frequently in patients with liver cirrhosis than in non-cirrhotic patients. Surgery is required if symptoms or complications related to the presence of gallstones occur and a thorough preoperative evaluation and optimization of patient’s condition is necessary prior to surgery. The procedure of choice in these situations is laparoscopic cholecystectomy. The technique has some particularities resulting from local anatomical changes and conversion to open technique remains low and morbidity and mortality rates are within acceptable limits.

Does Gallbladder Wall Thickening of Cirrhotic Patients Increase the Risk of Formation of Gallstones?

The objective of this study was to investigate whether gallbladder wall thickening in cirrhotic patients adds risk to the formation of gallstones. In this retrospective study, 259 patients with cirrhosis resulting from hepatitis B or hepatitis C were included (152 men, 107 women; mean ± SD, age 48.8 ± 11.4 years [range, 29–77 years]) and compared with 300 healthy participants comprising the control group. All participants had a standard abdominal sonographic assessment. The prevalence of gallstones in cirrhotic patients with and without gallbladder wall thickening was studied, and the distribution of gallstones and gallbladder wall thickening in different Child-Pugh classes was compared. The prevalence of gallstones in cirrhotic patients, cirrhotic patients with and without gallbladder wall thickening, and healthy participants was 27.4%, 28.8%, 13.0%, and 5.3%, respectively. The prevalence of gallstones in cirrhotic patients with gallbladder wall thickening was not significantly higher than in those without gallbladder wall thickening ( P > .05). Gallbladder wall thickening occurred with a higher frequency in Child-Pugh B and C patients, and normal thickness of the gallbladder wall was seen more frequently in Child-Pugh A patients ( P < .05). Gallstones were found more frequently in Child-Pugh A and C patients ( P < .05). In conclusion, gallbladder wall thickening in cirrhotic patients does not significantly add any risk for the formation of gallstones.

Concept of the pathogenesis and treatment of cholelithiasis

Gallstone disease (GD) is a chronic recurrent hepatobiliary disease, the basis for which is the impaired metabolism of cholesterol, bilirubin and bile acids, which is characterized by the formation of gallstones in the hepatic bile duct, common bile duct, or gallbladder. GD is one of the most prevalent gastrointestinal diseases with a substantial burden to health care systems. GD can result in serious outcomes, such as acute gallstone pancreatitis and gallbladder cancer. The epidemiology, pathogenesis and treatment of GD are discussed in this review. The prevalence of GD varies widely by region. The prevalence of gallstone disease has increased in recent years. This is connected with a change in lifestyle: reduction of motor activity, reduction of the physical load and changes to diets. One of the important benefits of early screening for gallstone disease is that ultrasonography can detect asymptomatic cases, which results in early treatment and the prevention of serious outcomes. The pathogenesis of GD is suggested to be multifactorial and probably develops from complex interactions between many genetic and environmental factors. It suggests that corticosteroids and oral contraceptives, which contain hormones related to steroid hormones, may be regarded as a model system of cholelithiasis development in man. The achievement in the study of the physiology of bile formation and the pathogenesis of GD has allowed expanding indications for therapeutic treatment of GD.

Ultrasonographic study of gallbladder wall thickness and emptying in cirrhotic patients without gallstones

Background and Aim. Gallbladder wall thickening and impaired contractility are currently reported in cirrhotic patients and often related to portal hypertension and hepatic failure. The purpose of this work was to evaluate, by ultrasonographic method, gallbladder wall thickness and gallbladder emptying after a standard meal in normal subjects and in patients with compensated liver cirrhosis without gallstones. Methods. Twenty-three patients with Child-Pugh class A liver cirrhosis and twenty healthy controls were studied. Gallbladder wall thickness (GWT), gallbladder fasting volume (FV), residual volume (RV), and maximum percentage of emptying (%E) were calculated. Measurements of mean portal velocity, portal vein flow, and serum albumin were performed too. Statistical analysis was assessed by Student's “t test” for unpaired data. Results. GWT was 0.60 ± 0.22 cm in cirrhotic patients and 0.21 ± 0.06 cm in controls (P < .0001). FV and RV were, respectively, 37.8 ± 3.7 cm³ and 21.8 ± 3 cm³ in cirrhotic patients, 21.9 ± 4.2 cm³ and 4.6 ± 2.2 cm³ in healthy volunteers (P < .0001). %E was smaller in cirrhotics (42.6 ± 7.8) as compared to controls (80.3 ± 7.2; P < .0001). Conclusions. In patients with compensated liver cirrhosis without gallstones gallbladder wall thickness is increased whereas its contractility is reduced. These early structural and functional alterations could play a role in gallstone formation in more advanced stages of the disease.
