Pancreatitis crónica: más allá del alcohol

Chronic pancreatitis. Some important historical aspects

Since ancient times the increase of size and hardness sometimes presented by the abdominal structure known as the pancreas has attracted attention. Portal was the first to describe the clinical signs of chronic pancreatitis in 1803. In 1815, Fleischman speculated about the potential role of excessive alcohol consumption. Comfort coined the term "chronic relapsing pancreatitis" in 1946 and described hereditary pancreatitis 6 years later. Zuidema defined tropical pancreatitis in 1959 and 2 years later Sarles described another form of pancreatitis to which Yoshida gave the name autoimmune pancreatitis in 1995. Groove pancreatitis was described by Potet in 1970. Obstructive pancreatitis was defined in 1984 and Ammann identified idiopathic pancreatitis 3 years later. This article gives a historical account of the pioneers who developed the knowledge of how to assess the characteristics that allowed the different forms of chronic pancreatitis to be defined.

Exocrine pancreatic insufficiency and chronic pancreatitis in chronic alcoholic liver disease: coincidence or shared toxicity?

OBJECTIVES

The aims of this study were to determine the prevalence of exocrine pancreatic insufficiency (EPI) and chronic pancreatitis (CP) in patients with chronic alcoholic liver disease and to analyze the possible associated factors.

METHODS

This is an analytical observational study of cases and controls for a sample of patients with chronic alcoholic and nonalcoholic liver disease. Exocrine pancreatic insufficiency was diagnosed using the C mixed-triglyceride breath test. Patients with abdominal pain underwent endoscopic ultrasonography for CP evaluation using the Wiersema criteria.

RESULTS

A total of 154 patients were included, 129 with alcoholic liver disease (83 with cirrhosis) and 25 with nonalcoholic liver disease. Exocrine pancreatic insufficiency was found in 55.2% versus 16.7% (P < 0.001), 70% of patients without cirrhosis compared with 46.2% of patients with cirrhosis had pancreatic insufficiency (P = 0.017), and 82.7% of patients with alcoholic liver disease and abdominal pain had CP (P < 0.001). Exocrine pancreatic insufficiency was associated with the male sex, alcohol intake, abdominal pain, degree of liver failure, and the absence of portal hypertension. Chronic pancreatitis was correlated with age younger than 55 years and abdominal pain.

CONCLUSIONS

Patients with alcoholic liver disease had a high prevalence of EPI and CP; this prevalence was even higher in patients who have not yet developed cirrhosis with liver failure or portal hypertension.
