[Risk factors for cholecystolithiasis in obesity and at normal weight].

Obesity is a known risk factor of cholecystolithiasis. The potential causes of increased incidence of cholecystolithiasis in people with obesity (overweight) and in those with normal body mass are considered. The study involved 100 patients with diagnosed cholecystolithiasis hospitalized in one of the randomly selected hospitals in Bialystok and its vicinity. The questionnaire technique was used to evaluate risk factors of cholecystolithiasis. It was found that women, irrespective of body mass, were 2.7 times more often hospitalized due to this ailment than men. Of the patients examined, 71% had overweight or obesity. Women with normal body mass suffered from cholecystolithiasis at the younger age than the obese or overweight ones. The comparison of risk factors of cholecystolithiasis between the obese (overweight) patients and those with normal body mass revealed a significantly more frequent familial incidence of type 2 diabetes and cholecystolithiasis. Patients with cholecystolithiasis, irrespective of body mass, were characterized by low intake of dark bread and wholemeal products, raw fruit and vegetables, and pulses. Obese women with cholecystolithiasis significantly more frequently consumed milk and yoghurt, meat and its products, lard, bacon and sweets than women with normal body mass. Obese men (with overweight) significantly more frequently consumed high-fat foods than the slim ones.

Prospective evaluation of endoscopic ultrasonography and microscopic examination of duodenal bile in the diagnosis of cholecystolithiasis in 45 patients with normal conventional ultrasonography.

The aim of this study was to prospectively evaluate endoscopic ultrasonography and microscopic examination of duodenal bile in the diagnosis of cholecystolithiasis not detected by conventional ultrasonography. Forty five consecutive patients (26 females, 19 males, mean age: 50 years) with suspected cholecystolithiasis and at least two normal transcutaneous ultrasonography examinations were included. Endoscopic ultrasonographic criteria for the diagnosis of cholecystolithiasis were the presence of stones with or without acoustic shadowing or sludge. Criteria of microscopic examination of bile were cholesterol or bilirubinate crystals or spheroliths. Thirty three patients underwent cholecystectomy and lithiasis was found in gall bladder bile in 24. Twelve patients who were not operated on and were followed up (median: 17 months), had no evidence of cholecystolithiasis. Endoscopic ultrasonography and duodenal bile examination were 96% and 67% sensitive, respectively (p < 0.03). The specificity was not different (86 and 91%, respectively). None of the 16 patients with negative results in both procedures had evidence of cholecystolithiasis. It was found that for the diagnosis of cholecystolithiasis in patients with normal conventional ultrasonography, the sensitivity of endoscopic ultrasonography is higher than that of microscopic examination of duodenal bile. If endoscopic ultrasonography and microscopic examination of duodenal bile are negative, the risk of underdiagnosing cholecystolithiasis is negligible.

[Nanobacteria in serum, bile and gallbladder mucosa of cholecystolithiasis patients].

OBJECTIVE: To find the distribution of nanobacteria in the serum, bile and gallbladder mucosa of cholecystolithiasis patients. METHODS: The infection rate of nanobacteria was identified by ELISA in the serum samples from 338 healthy people and 76 patients with cholecystolithiasis (chi(2) = 0.89, P > 0.05). Nanobacteria were cultured from the bile samples in 57 patients with cholecystolithiasis and 18 non-cholelithiasis patients and identified by immunohistochemical staining and TEM (chi(2) = 29.80, P < 0.05). Forty samples of gallbladder mucosa randomly selected from the 57 cholecystolithiasis patients were identified by immunohistochemical staining and compared with the corresponding bile samples. RESULTS: The infection rate of nanobacteria was 8.0% and 31.6% for the serum samples of the healthy people and cholecystolithiasis patients, respectively. The positive rate of nanobacteria in the bile samples was 61.3% and there was no significant difference in the bile of the cholecystolithiasis patients and the control group (61.4% vs. 61.1%). Fourteen positive patients had infection of nanobacteria in the gallbladder mucosa, submucosa, and calcific field. CONCLUSIONS: The infection rate of nanobacteria was 8% in the serum samples from the healthy people. There are nanobacteria in the serum, bile, and gallbladder mucosa. The infection of the nanobacteria may result in calcification and fibrosis of the gallbladder.

The prevalence and incidence of cholecystolithiasis in patients with chronic liver diseases: a prospective study.

To investigate the prevalence and incidence of cholecystolithiasis in hepatitis B surface antigen-positive chronic liver diseases, a prospective study using hepatobiliary ultrasonography was conducted in 933 "healthy" persons and four groups of HBsAg-positive patients: 226 asymptomatic carriers, 73 patients with chronic active hepatitis, 77 patients with early liver cirrhosis and 124 patients with advanced liver cirrhosis. Patients with hepatocellular carcinoma or alcoholism were excluded. The prevalences of cholecystolithiasis increased along with the increasing duration and severity of chronic liver diseases, with a significant linear trend (p less than 0.001). The prevalences of cholecystolithiasis in patients with liver cirrhosis (18.5% in males, 31.2% in females) were 4 to 5.5 times higher than that of the healthy population (p less than 0.005). In addition, the linear trend of increasing prevalence with increasing age in the healthy population was not observed in patients with chronic liver diseases. On the other hand, five of the 69 patients with early liver cirrhosis were found to develop cholecystolithiasis during a mean follow-up period of 32 months. The calculated annual incidence of cholecystolithiasis was 2.6%. The results suggest that chronic liver disease, particularly liver cirrhosis, is a risk factor for cholecystolithiasis.

[Cholecystolithiasis in the urban population of Poland].

Multicentre study was carried out in three regions of Poland aimed to assess cholecystolithiasis incidence in urban population and some potential risk factors of the disease. 10133 persons in five age groups, from 16 to 70 (6071 women and 4062 men) were examined. The examination consisted of questionnaire considered sex, age, weight, dietary habits, complaints, chronic drugs use, family history and in women number of pregnancies and deliveries as well as hormone therapy. The results obtained were analysed statistically with Chi 2 test. Cholecystolithiasis was found in 1411 persons (10.7%), among them 18% women (1083 women) and 8.2% men (328 men). Incidence rate was 180.5/1000 women and 82.0/1000 men. The obtained increase in percentage of cholecystolithiasis cases with age was statistically significant. No relation were found between the number of stones and sex of the examined persons. In 1480 persons (43.5%0 the disease was asymptotic. The studies did not prove the correlation between cholecystolithiasis in women and sex of the first child or oral contraception. Positive correlation was found between cholecystolithiasis in women, obesity, number of pregnancies and family history. In men age was most significant risk factor. Incidence of cholecystolithiasis in Poland, Western Europe and USA is similar.

Transforming growth factor-beta pathway is activated in cholecystolithiasis.

BACKGROUND: The etiopathogenesis of cholecystolithiasis is not well defined. Primary dysmotility of the organ, due to fibrosis of the gallbladder wall or muscular dysfunction, is suggested as a crucial factor. Transforming growth factor-beta (TGF-beta) and connective tissue growth factor (CTGF) are involved in several fibrotic disorders and play a critical role in fibrogenesis, thereby changing the physiological function of the organs. In the present study we analyzed the role of TGF-beta and its downstream target CTGF in patients with cholecystolithiasis. METHODS: Gallbladders were obtained from 16 individuals undergoing surgery for symptomatic cholecystolithiasis. Normal human gallbladder tissue samples from five individuals without any history of gallbladder disease were obtained through an organ donor transplantation program. Northern blot analysis, in situ hybridization, and immunohistochemistry were used to analyze the expression of TGF-beta1 and CTGF in the gallbladder tissue samples. RESULTS: By northern blot analysis there was an enhanced TGF-beta1 mRNA expression (eightfold increase; P < 0.04) in the cholecystolithiasis tissue samples in comparison with normal controls. There was also a concomitant increase in CTGF (41-fold increase; P < 0.01). By in situ hybridization and immunohistochemistry, CTGF mRNA was localized mainly in the mucosa layer, while intensive staining of the smooth muscle cells with TGF-beta1 and CTGF was observed. In addition, TGF-beta1 immunoreactivity was also localized in the fibroblasts and inflammatory cells. TGF-beta1 m-RNA levels showed a significant relationship with the degree of fibrosis in the tissue samples (P < 0.04, r = 0.5). CONCLUSION: Our data indicate that TGF-beta and CTGF are involved in ultrastructural tissue changes in patients with cholecystolithiasis. Activation of the "TGF-beta pathway," predominantly in the remaining mucosa and submucosal layer, indicates that extracellular matrix (ECM) synthesis with subsequent gallbladder wall fibrosis is an important step in gallbladder dysfunction in this disorder.

Is drip infusion cholecystocholangiography (DIC) an acceptable modality at cholecystectomy for cholecystolithiasis, considering the frequency of bile duct maljunction and intraoperative bile duct injury?

BACKGROUND/PURPOSE: Knowledge of the configuration of the extrahepatic bile duct is indispensable to avoid bile duct injury during cholecystectomy. Various methods of examining the biliary tract have been developed; however, the most appropriate preoperative diagnostic modality at cholecystectomy for cholecystolithiasis has not yet been reported. Considering the frequency of bile duct maljunction (BDM) and operative bile duct injury, in addition to the cost and invasiveness of the various examination methods, we evaluated the usefulness of drip infusion cholecystocholangiography (DIC) as the optimal method of examination at cholecystectomy for cholecystolithiasis. METHODS: Preoperative diagnostic accuracy of BDM was analyzed in relation to operative bile duct injury using 469 patients with benign biliary diseases who was diagnosed with DIC and endoscopic retrograde cholecystography and underwent cholecystectomy. BDM was classified according to Hisatsugu criteria. RESULTS: Out of 469 consecutive patients who underwent a cholecystectomy for biliary stones between January 1, 1995, and September 30, 1998, at Ohta Nishinouchi General Hospital, 21 (4.48%) had a cystic duct maljunction (CDM) and 12 (2.56%) had an aberrant bile duct (ABD). The most common variants were types C and D for CDM, and types II and III for ABD, according to Hisatsugu's classification. Fourteen patients (42.4%) were diagnosed before the surgery; 13 of them received preoperative endoscopic retrograde cholangiography (ERC), and the remaining patient underwent preoperative drip infusion cholecystocholangiography (DIC). Nineteen patients could not be correctly diagnosed based on their preoperative examinations, but were diagnosed during surgery. Operative bile duct injury occurred in 1 patient (0.2%) whose maljunction could not be diagnosed before the operation. CONCLUSIONS: Taking into account the medical cost and invasiveness, and the frequency of BDM and related bile duct injuries, we conclude that DIC is an acceptable preoperative diagnostic modality to employ at cholecystectomy for cholecystolithiasis. Knowledge of the configuration of the extrahepatic bile duct is indispensable to avoid bile duct injury during cholecystectomy. Various methods of examining the biliary tract have been developed; however, the most appropriate preoperative diagnostic modality at cholecystectomy for cholecystolithiasis has not yet been reported.

Segmental adenomyomatosis of the gallbladder predisposes to cholecystolithiasis.

BACKGROUND/PURPOSE: The aim of the present study was to clarify the association between adenomyomatosis of the gallbladder and cholecystolithiasis. METHODS: A cholecystectomy was performed for cholelithiasis or various other conditions in 1099 patients, of whom 608 had cholecystolithiasis. Adenomyomatosis of the gallbladder was classified as one of three variants: segmental, fundal, and diffuse. Segmental adenomyomatosis has an annular stricture dividing the gallbladder lumen into the "neck compartment" and the "fundal compartment". Bile lipid analysis was performed in 8 patients with segmental adenomyomatosis. RESULTS: Adenomyomatosis of the gallbladder was observed in 156 patients (14.2%), of whom 99 had segmental adenomyomatosis, 54 had fundal adenomyomatosis, and 3 had diffuse adenomyomatosis. The prevalence of cholecystolithiasis was higher in patients with segmental adenomyomatosis (88.9%) than in those without adenomyomatosis (52.3%; P < 0.001). Gallstones were detected earlier in patients with segmental adenomyomatosis than in those without ( P < 0.001) and were located predominantly in the fundal compartment. Bile in the fundal compartment had lower concentrations of total bile acids ( P = 0.012), with an increased cholesterol saturation index ( P = 0.012), compared to bile in the neck compartment. CONCLUSIONS: Segmental adenomyomatosis is a condition predisposing to cholecystolithiasis, probably due to the lithogenic environment in the fundal compartment. Fundal or diffuse adenomyomatosis appears to be unrelated to cholecystolithiasis.

Prevalence and incidence of cholecystolithiasis in cirrhosis and relation to the etiology of liver disease.

To assess prevalence and incidence of cholecystolithiasis in cirrhosis, 356 consecutive cirrhotics and 247 consecutive cases of chronic hepatitis without cirrhosis were studied by ultrasonography. Cholecystolithiasis was significantly more frequent in cirrhotics than in patients with chronic hepatitis (p < 0.001) after stratification for age and for alcohol abuse, and its prevalence in the former was affected by Child's class (p < 0.001) and duration (p < 0.001) of cirrhosis and was higher in HBsAg-negative as compared with HBsAg-positive cases (36.2 vs. 11.9%) and in patients with previous alcohol abuse (41.5 vs. 28.3%), while no difference was noted in relation to sex. By multivariate analysis, duration and Child's class of cirrhosis and HBsAg-negative status were statistically associated with cholecystolithiasis. One hundred and eighty-two of the 356 cirrhotic patients without gallstones at inclusion were followed prospectively, and 21 (11.5%) of them developed cholecystolithiasis, and duration of cirrhosis and past alcohol abuse were found to be independent risk factors for gallstone development by multivariate analysis. Cirrhosis is a significant risk factor for cholecystolithiasis, except for HBsAg-positive patients who have prevalence and incidence similar to noncirrhotics. Severity and duration of cirrhosis and previous alcohol abuse are associated with an increased risk of gallstone formation.

Elevated cholecystokinin-like activity in the duodenal mucosa in patients with cholecystolithiasis.

Cholecystokinin (CCK)-like activities in the duodenal mucosa of the patients with cholecystolithiasis were determined with the bioassay method we established. The results obtained are as follows: The gall bladder of the patients with cholecystolithiasis following oral administration of egg yolk has contraction rates comparable to those of the normal subjects in the control group, whereas the contraction rate of the gall bladder of the patients with cholecystolithiasis following administration of caerulein was markedly lower than that of the normal subjects in the control group. The variations in the contraction of the gall bladder in time lapse following administration of caerulein to the patients with cholecystolithiasis strongly denied the possibility of either insufficient release of CCK or accelerated dissimilation of CCK in those patients. Based on the above findings, it was concluded that the sensitivity of the gall bladder to CCK decreases in the patients with cholecystolithiasis and that, in order to replenish it, the feed-back mechanism reacts to sufficiently promote the production of CCK in the duodenal mucosa. The similar mechanism was noted in the variations of the findings of normal subjects as age advanced.

[The assessment of the risk of large bowel cancer in patients operated on cholecystolithiasis].

In the recent years reports have become available suggesting more frequent incidence of colorectal cancer in patients who earlier had cholecystectomy performed as well as in those with unoperated cholecystolithiasis. The divergent views of many authors became the cause of studying of the incidence of past cholecystectomy and cholecystolithiasis in patients operated on for colorectal cancer and comparing of this incidence with that in the control group selected on the basis of own material. The incidence of cholecystectomy and unoperated cholecystolithiasis was assessed in 90 patients treated for colorectal cancer of various location and was compared with the control group of 90 patients treated for other reasons than neoplastic disease. Both groups were selected with respect to gender, age and hospitalisation duration. In the analysis performed no significantly greater frequency of cholecystectomy and cholecystolithiasis was found in patients with colorectal cancer as compared to the control group. Such difference was neither observed considering cancer location and gender of the studied subjects (p < 0.05). Taking into account age over 60 years, more frequent cholecystectomy was found in the case of cancer of the right half of the colon in both genders in the group of patients with colorectal cancer as compared to the control group (p = 0.031). The relative risk for cancer development was in this case 4.5. In these patients cholecystectomy was performed 14.9 years on the average before cancer diagnosis. The patients in older age with cholecystolithiasis should be evaluated for the presence of coexistent colorectal cancer prior to laparoscopic cholecystectomy.

[Asymptomatic cholecystolithiasis in an ultrasonography study from Trencín].

The author examined 1952 girls and women aged 15 to 92 years by ultrasonography. The incidence of cholecystolithiasis in the group without complaints was 8.19% in the group with atypical complaints it was 17.67% and in the group with typical complaints it was 75.0%. The ratio of asymptomatic cholecystolithiasis of the first two groups combined was 67.0% of the total. The ratio of cholecystectomies in the total number of cases with cholecystolithiasis was 30.9%. The clinical manifestation of cholecystolithiasis is influenced greatly by genetic factors, i.e. symptomatic lithiasis in the mother. Prophylactic cholecystectomy in case of asymptomatic cholecystolithiasis should not be recommended.

Relationship between cholecystolithiasis and polypoid gallbladder.

OBJECTIVE: To study the relationship between cholecystolithiasis and polypoid gallbladder (PLG), 260 patients with polypoid gallbladder were investigated. The patients were divided into 2 groups: group A (PLG combined with cholecystolithiasis) and group B (without cholecystolithiasis). The clinical pathological characteristics were analyzed. The intestinal epithelium metaplasia and atypical hyperplasia of the gallbladder mucosa were observed under light microscope. RESULTS: Intestinal epithelium metaplasia and atypical hyperplasia of gallbladder mucosa were found in 47 of the 260 cases. The pathological lesions included 16 gallbladder carcinoma, 11 adenomatosis polyp, 5 myoadenoma, 7 cholesterol polyp, 4 inflammatory polyp and 4 adenomatosis hyperplasia, which occurred in 26 and 21 patients in group A and group B, i.e. 44.0% and 10.3% respectively. The difference between group A and group B was statistically significant (P<0.01). CONCLUSION: Cholecystolithiasis and the succeeding inflammatory reaction is a risk-factor for the polypoid gallbladder to develop tumour.

Long-term outcome of endoscopic papillotomy for choledocholithiasis with cholecystolithiasis.

BACKGROUND: Although endoscopic papillotomy is now considered established treatment for choledocholithiasis, therapeutic results of endoscopic papillotomy alone without subsequent cholecystectomy in patients with cholecystolithiasis have not been well evaluated. The aim of this study was to assess the long-term outcome of endoscopic papillotomy for these patients. METHODS: Patients admitted with choledocholithiasis and cholecystolithiasis from 1976 to 1993 were studied retrospectively. Of 385 patients in whom the bile duct was cleared by endoscopic papillotomy and endoscopic stone extraction, 371 patients (195 men and 176 women; mean age 65.4 years) were followed. Predisposing risk factors for late complications were analyzed. RESULTS: The mean duration of follow-up was 7.7 years. Cholecystitis and recurrence of choledocholithiasis as late complications occurred in 22 cases (5.9%) and 36 cases (9.7%), respectively. Cholecystitis, including 1 severe case, resolved with conservative treatment. Recurrent choledocholithiasis was successfully treated endoscopically except in 1 case. No significant risk factors were identified for cholecystitis. The presence of pneumobilia (p = 0.0016) and the need for lithotripsy (p = 0.0342) were found to be significant risk factors for the recurrence of choledocholithiasis. CONCLUSIONS: Long-term outcome of endoscopic papillotomy in patients with choledocholithiasis and cholecystolithiasis was found to be relatively favorable. Cholecystectomy after endoscopic papillotomy is not always necessary in the management of cholecystolithiasis.

Cholecystolithiasis in patients with end-stage renal disease treated with haemodialysis: a study of prevalence.

Gallstones are quite prevalent in western countries (10-20% of adult population), but there are very few data about the prevalence of cholecystolithiasis in haemodialysis (HD) patients. In our study, we found--with real-time ultrasound--a prevalence of gallstones of 16% in patients with end-stage renal disease (ESRD) treated with HD which is similar to the prevalence in a non-uraemic control group matched for age and sex. In most of our HD patients, cholecystolithiasis was asymptomatic. HD patients with cholecystolithiasis were statistically significantly older than patients without gallstones. We found no differences in sex or duration of HD treatment in patients with and without cholecystolithiasis. The prevalence of cholecytolithiasis in patients with ESRD on HD is similar to that of a normal population though some data suggested a higher prevalence in HD patients.

[Carcinogenicity of bile from cholecystolithiasis patients].

OBJECTIVE: To study the carcinogenicity of bile from cholecystolithiasis patients and the relationship between cholecystolithiasis and gallbladder carcinoma (GBC). METHODS: The bile from 18 cholecystolithiosis patients was examined by Ames test and two-stage cell transformation assay. RESULTS: The bile from cholecystolithiosis patients could significantly promote the formation of BALB/c3T3 cell transformation (P = 0.0233). The bile from symptomatic patients was much more active in tumor promotion than that from asymptomatic patients (P < 0.05). CONCLUSION: The bile in cholecystolithiasis patients exhibits a tumor-promoter activity, which may account for the high incidence of GBC among cholecystolithiasis patients.

[Cholecystolithiasis in type II diabetics].

In a group of 166 type II diabetics hospitalized in a medical department the authors made clinical and ultrasonographic examinations focused on the presence of cholecystolithiasis. The control group was formed by 67 subjects with normal glucose tolerance. None of the patients were hospitalized on account of biliary disease. The purpose of the work was to 1. evaluate the difference in the incidence of cholecystolithiasis in diabetic patients and controls with regard to age and sex, 2. to assess differences in the incidence of obesity, impaired lipid metabolism and a positive biliary family--history in diabetics and controls with lithiasis, 3. to evaluate diabetes and the presence of microalbuminuria. In the authors' group cholecystolithiasis is significantly more frequent in diabetics as compared with controls, in men, women and people above 65 years (p less than 0.01). The group of diabetics and controls with lithiasis does not differ as to the incidence of obesity, hyperlipoproteinaemia and positive family-history of biliary disease. No significant differences in parameters of compensation of diabetes nor differences in the incidence of microalbuminuria were found between diabetics with and without lithiasis. The results suggest that it is useful to screen cholecystolithiasis in diabetic subjects.

Somatosensory changes in the referred pain area in patients with cholecystolithiasis.

BACKGROUND AND AIMS: Patients with abdominal pain provoked by acute cholecystitis increase the somatic sensitivity in the referred somatic pain area. Our aim in the present paper was to examine somatosensory changes in the referred pain area (previously evoked by painful attacks) in patients with uncomplicated gallstone disease and to evaluate the possible relation between referred pain patterns and clinical findings. Somatosensory changes in these areas may be important in the persistent pain after treatment and may help to develop treatment strategies for abdominal pain in the post-cholecystectomy syndrome. SUBJECTS: Forty-two patients with symptomatic cholecystolithiasis, confirmed ultrasonographically, were studied in the pain-free period. METHODS: Sensitivity and pain thresholds for standardized experimental sensory testing including different modalities: pinprick, pinching, heat, cold, pressure, and single and repeated electrical stimulation were studied in the area where the pain was referred to during the acute attacks, and in a control area on the contralateral side of the abdomen. RESULTS: Patients with verified cholecystolithiasis showed hyperalgesia to pinprick (26% of subjects, P < 0.05) and cold stimuli (21% of subjects, P < 0.05) in the referred pain area. There was also a significant reduction in sensation/pain thresholds (indicating hyperalgesia) in the referred pain area to single (P = 0.007/P = 0.002) and repeated electrical (P = 0.017/P = 0.043) stimuli, as well as in pain threshold to pinching and mechanical stimuli (P = 0.049/P < 0.001). There were no significant relations between the hyperalgesia and the clinical findings. CONCLUSION: Cholecystolithiasis leads to significant hyperalgesia in the somatic area, where pain was referred to during the acute attacks. This is explained by viscero-somatic convergence mechanisms in the central nervous system. Therefore, central neuroplastic changes may be significant in diseases related to the gallbladder such as the post-cholecystectomy syndrome.
