A prospective study of pancreatic disease in patients with alcoholic cirrhosis: comparative diagnostic value of ERCP and EUS and long-term significance of isolated parenchymal abnormalities.

BACKGROUND: The prevalence of pancreatic disease in patients with alcohol-related liver cirrhosis is uncertain. We assessed the prevalence of pancreatic abnormalities in patients with alcoholic cirrhosis, and we compared endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) for the detection of chronic pancreatitis and other pancreatic lesions. In addition, we assessed the long-term significance of isolated pancreatic parenchymal abnormalities detected at EUS. METHODS: EUS and ERCP were performed in each patient. Subjects with minimal parenchymal changes at initial EUS underwent clinical follow-up and subsequent EUS and/or ERCP to document the occurrence, absence, or progression of these changes. RESULTS: Seventy-two patients with alcoholic cirrhosis were recruited. Chronic pancreatitis was diagnosed in 14 patients (19%) by both methods independently. Isolated parenchymal lesions were observed in 18 patients by EUS alone. After a mean follow-up of 22 months the EUS appearance was unchanged. Ten of the 18 patients underwent follow-up ERCP and this was normal in all cases. CONCLUSIONS: This study demonstrated that (1) 19% of patients with alcoholic cirrhosis have chronic pancreatitis, (2) an additional 25% have isolated pancreatic parenchymal changes at EUS, and (3) these parenchymal abnormalities do not progress during follow-up.

Prevalence of cholelithiasis: results of an epidemiologic investigation in Vidauban, southeast France. General Practitioner's Group of Vidauban.

Cholelithiasis leads to 80,000 cholecystectomies being performed every year in France, but its prevalence is still unknown. The aim of this study was to assess the prevalence and risk factors of cholelithiasis in a random population of 1027 women and 727 men over the age of 30 in a small town in the southeast of France. Detailed clinical history, dietary investigation, and gallbladder ultrasound were collected for each subject and assessed by univariate analysis. A regression model was used in the multivariate analysis to detect the relative risk of cholelithiasis. Cholelithiasis was found in 130 individuals (global prevalence 13.9%). The relative risk for lithiasis was higher in women compared to men (1.89). Age (P<0.0001) and body mass index (BMI) >25 (P = 0.013) were also significant risk factors. Neither pregnancy nor oral contraceptive use proved to be risk factors. Typical biliary colic pain was the only symptom significantly associated with cholelithiasis (P<0.0001). These results show that the prevalence of gallstones in France is similar to that in Denmark and Italy.

The role of endoscopic retrograde cholangiopancreatography in the management of hepatic hydatid disease.

BACKGROUND AND STUDY AIMS: Hydatid disease of the liver, and its complications, causes serious morbidity and mortality. We evaluated the role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of hepatic hydatid disease. PATIENTS AND METHODS: This retrospective analysis includes 28 patients with hepatic hydatid disease who underwent ERCP. ERCP was performed preoperatively in 11 patients, for acute cholangitis (n =7), acute pancreatitis (n = 1) and right upper quadrant pain (n = 3), and in eight asymptomatic cases to search for fistulae between the cyst and the biliary tree. In a further nine patients ERCP was performed for early (< 30 days; n = 7) and late (n = 2) postoperative biliopancreatic problems. RESULTS: In all seven patients with cholangitis preoperative ERCP with EST and ductal clearance of daughter cysts and debris led to substantial clinical improvement, including four acutely ill elderly patients who stabilized and were later able to undergo surgery. EST in two of the three patients with pain who had papillary stenosis led to resolution of the abdominal pain. Six of the seven postoperative fistulae could be successfully treated endoscopically using EST. CONCLUSIONS: This study demonstrates the usefulness of ERCP in symptomatic patients with hepatic hydatid cysts; EST enables clearance of the common bile duct and allows healing of postoperative fistulae in the majority of patients. We do not, however, recommend performing routine preoperative ERCP in asymptomatic patients with the disease.

Long term treatment of biliary stricture due to chronic pancreatitis with a metallic stent.

The exact role of endoprostheses in the management of chronic pancreatitis-associated biliary strictures has not yet been clearly established. We report an unusual case of a patient with this condition who was treated for an unexpectedly long term with a self-expanding metallic endoprosthesis. There has only been one previous report of the use of metallic stents in this situation. It appears that metallic endoprostheses may have a role to play in the management of selected patients who have chronic pancreatitis-associated bile duct stricture.

Chronic pancreatitis and inflammatory bowel disease: true or coincidental association?

OBJECTIVE: Several cases of pancreatitis have been described during the course of Crohn's disease (CD) or ulcerative colitis (UC), but many of them were related to either biliary lithiasis or drug intake. We tried to evaluate the clinical and morphological features of so-called idiopathic pancreatitis associated with inflammatory bowel disease and to define their pathological characteristics. METHODS: Chronic idiopathic pancreatitis was diagnosed on the basis of abnormal pancreatograms suggestive of chronic pancreatitis associated with or without impaired exocrine pancreatic function, or pathological examination in patients undergoing pancreatic resection. We found 6 patients presenting with features of chronic idiopathic pancreatitis and UC and 2 patients with CD seen between 1981 and 1996 in three hospital centers of the south of France. A review of the literature has identified 6 cases of pancreatitis associated with UC and 14 cases of pancreatitis associated with CD based on the above criteria. RESULTS: Hyperamylasemia was not a sensitive test since it was present in 44% and 64% of patients with UC or CD. In UC, pancreatitis was a prior manifestation in 58% of patients. In contrast, the pancreatitis appeared after the onset of CD in 56% of the cases. In patients with UC, pancreatitis were associated with severe disease revealed by pancolitis (42%) and subsequent surgery. Bile duct involvement was more frequent in patients with UC than with CD (58% vs 12%) mostly in the absence of sclerosing cholangitis (16% vs 6%). Weight loss and pancreatic duct stenosis were also more frequent in UC than in CD (41% vs 12% and 50% vs 23%, respectively). Pathological specimens were analyzed in 5 patients and demonstrated the presence of inter- and intralobular fibrosis with marked acinar regression in 3 and the presence of granulomas in 2 patients, both with CD. CONCLUSIONS: Pancreatitis is a rare extraintestinal manifestation of inflammatory bowel disease. Chronic pancreatitis associated with UC differs from that observed in CD by the presence of more frequent bile duct involvement, weight loss, and pancreatic duct stenosis, possibly giving a pseudotumor pattern.

[Ultrasonographic and MRI aspects of cystic duodenal dystrophy with aberrant pancreatic tissue].

US and MR features (including MR cholangiopancreatography) of a cystic formation in a duodenal heterotopic pancreas are reported. To our knowledge, MR cholangiopancreatography of this uncommon condition has not been previously described. Imaging showed multiple cysts within a thickened duodenal wall. This thickness of the duodenal wall was related to a heterotopic pancreas with chronic pancreatitis.

[Inflammatory pseudotumor of the intrahepatic biliary tract].

Hepatic inflammatory pseudotumors are rare, presenting with a severe clinical pattern mimicking neoplasm. The diagnosis is almost always based on pathological examination showing inflammatory lesions with a polymorphous infiltrate and variable amounts of fibrous tissue. Development in the biliary tract is rare. We report the case of a 53-year-old patient who was referred for poor general condition and jaundice; the initial diagnosis was cholangiocarcinoma. Pathological examination of the surgical specimen showed a right intrahepatic biliary duct inflammatory pseudotumor. The patient developed recurrent jaundice three months after surgery due to a lesion of the left biliary ducts. Treatment with cortisone resulted in rapid improvement of jaundice.

Extensive aetiological investigations in acute pancreatitis: results of a 1-year prospective study.

BACKGROUND: Epidemiological data on acute pancreatitis are poorly defined. AIMS: To prospectively evaluate the aetiology of acute pancreatitis and to assess the benefits of intensive investigations. METHODS: In a prospective, 1-year study all cases of acute pancreatitis in the Nice catchment area were enrolled. Subjects underwent routine (serum calcium, phosphate and triglycerides; abdominal ultrasonography and CT scan) and additional, delayed intensive investigations (ERCP with bile sampling and/or endoscopy ultrasonography). RESULTS: One hundred and twenty-one cases were included. After routine investigations, a biliary, alcoholic, miscellaneous or unknown origin was diagnosed in 43%, 31.4%, 9.9% and 15.7%, respectively. In subjects with biliary pancreatitis, 43% had no previous history of biliary disease. In the alcohol-related subgroup, pancreatitis recurred in 18.5% during 114.5 days mean follow-up. In subjects with a first episode of alcoholic pancreatitis, delayed supplemental investigations revealed underlying chronic pancreatitis in 92.8%. After routine investigations, a diagnosis of pancreatitis of unknown origin was made in 15.7% (n = 19) of subjects. Additional investigations revealed an underlying cause in 57.8% of these patients (n = 11), including malignancy (n = 3) and biliary disease (n = 4), reducing the overall rate of pancreatitis with no apparent cause to 6.6%. CONCLUSIONS: Investigative techniques, particularly ERCP, will reveal the underlying aetiology of pancreatitis in the majority of patients presenting with 'idiopathic' pancreatitis and should be considered when routine tests are negative.

A study of the effect of age on pancreatic duct morphology.

BACKGROUND: Interpretation of endoscopic pancreatograms is difficult in elderly patients. Age-related parenchymal changes and associated ductographic changes are ill-defined, and it is sometimes difficult to distinguish these from pathologic processes. METHODS: To define age-related pancreatogram changes, all endoscopic retrograde pancreatograms performed in patients older than 70 years of age over a 6-year period were analyzed and compared with those of a control group (younger than 50 years of age). RESULTS: Of the 136 elderly subjects included in the study, 31 (22.8%) were found to have definite pathology. Comparing the remaining 105 subjects with the control group, the mean main pancreatic duct diameter (in millimeters) was larger in the head (5.3 vs. 3.3), body (3.7 vs. 2.3), and tail (2.6 vs. 1.6) (p < 0.05). The duct diameter also increased significantly in each of the age cohorts (70 to 79, 80 to 89, and 90 to 99 years). Only 33 of 105 (31.4%) of the elderly patients had duct diameters within defined normal limits. In the majority (63.3%), dilatation was global but in a minority it was confined to the head and/or body. In 21 subjects the ductal diameter was greater than 2 standard deviations above normal, and in 5 subjects it was greater than 3 standard deviations above normal. Dilatation of secondary ducts was also observed. CONCLUSION: The majority of elderly patients who do not have pancreatic pathology have a dilated pancreatic duct by comparison with younger patients. Patient age must be considered when interpreting endoscopic pancreatograms.

Cholelithiasis and dietary risk factors: an epidemiologic investigation in Vidauban, Southeast France. General Practitioner's Group of Vidauban.

Dietary risk factors have been implicated in the development of cholelithiasis. The aim of this study was to determine in a homogeneous French population whether a particular type of diet may be lithogenic. Seventy-six subjects over 30 years of age (26 men, 50 women) with cholelithiasis detected by ultrasound were selected from a population sample of 830 subjects by drawing lots using the polling list. These were matched by 76 control subjects without cholelithiasis randomly selected from the same population. Univariate analysis was significant for a high calorie diet >2500 kcal/day (OR = 3.62, P = 0.0065), a diet rich in carbohydrates with a consumption > or = 55 g/day (OR = 2.98, P = 0.0067), and a diet rich in total lipids (OR = 4.97, P = 0.023) or saturated fatty acids (OR = 3.06, P = 0.0146). An alcohol consumption equivalent to 20-40 g/day was protective (P = 0.018). Multivariate analysis confirmed these results. Our study suggests that a change in dietary habits by limiting excess calories, saturated fats and carbohydrates could reduce the incidence of cholelithiasis.

First report of association of chronic pancreatitis, primary biliary cirrhosis, and systemic sclerosis.

We report an original observation of chronic pancreatitis associated with primary biliary cirrhosis and systemic sclerosis. The diagnosis of each of these conditions was unequivocally confirmed. Pancreatic involvement in this case was asymptomatic. The association of chronic pancreatitis with primary biliary cirrhosis has been previously reported and pancreatitis has been associated with other autoimmune disorders. We hypothesize about the underlying pathogenic mechanisms of chronic pancreatitis in our case.

Lack of influence of hepatitis G virus infection on alcohol-related hepatic lesions.

BACKGROUND: The purposes of this study were to analyse the prevalence and histologic impact of hepatitis G virus (HGV), a newly discovered virus, in alcoholic patients, a population known to be at risk for viral hepatitis. METHODS: One hundred and thirty-nine consecutive alcoholics admitted to our liver unit (106 men and 33 women; mean age, 47.1 +/- 10.9 years) were included in the study. All patients had consumed more than 60 g of ethanol per day for at least 1 year. One hundred healthy blood donors constituted a control group. Antibodies to HGV E2 protein and HGV-RNA testing by reverse transcription-polymerase chain reaction (RT-PCR) with primers derived from the NS5 coding region were performed in all serum samples. RESULTS: A significantly higher seroprevalence of anti-E2 antibodies was observed in alcoholic patients than in healthy blood donors (41 (29.5%) versus 8 (8%); P < 0.0001). Moreover, the prevalence of HGV-RNA was significantly higher in alcoholic patients (13 (9.3%) versus 1 (1%); P = 0.01). HGV-RNA and anti-HGV antibodies were never detected simultaneously. HGV viraemia was not associated with an increased risk of cirrhosis or hepatocarcinoma in alcoholic subjects. CONCLUSIONS: Our study reports a high prevalence of HGV in alcoholic patients. HGV infection does not modify or aggravate the course of alcoholic liver disease.
