Histomorphological Changes in Pancreas and Liver among Chronic AlcoholicsAn Autopsy Study

Abstract

Introduction: The clinical and pathological association between pancreatitis and alcohol abuse is well recognised, however the concurrence of prevalence of alcoholic related pancreatitis and liver disease is less well studied. Aim: To evaluate frequency of histomorphological changes in pancreas and liver among patients with history of alcohol abuse and observe the prevalence of coexistence between chronic pancreatitis and liver cirrhosis. Materials and Methods: This was observational cross-sectional study conducted in Department of Pathology at Lokmanya Tilak Municipal Medical College, Mumbai, Maharashtra, India, from July 2013 to July 2018. The study included 1917 autopsies and 107 cases with a documented history of chronic alcohol abuse. Haematoxylin and Eosin (H&E) staining was done on all sections and special stain like Masson’s trichrome was performed as per indication. Gross and microscopy were studied under variable defined parameters. Data was entered in Microsoft Excel sheets. Results: Histomorphologically, 12 cases (11.21%) were diagnosed as pancreatitis; 10 cases (9.34%) were of acute pancreatitis and two cases (1.86%) were of chronic pancreatitis. Total 21 cases were diagnosed as liver cirrhosis. The most dominant pattern of fibrosis seen in pancreatitis was perilobular and interlobular periductal fibrosis. The frequency of pancreatitis (14.28%) and pancreatic fibrosis (38.09%) was found to be more in cirrhotics. Chronic pancreatitis was commonly seen in cirrhotics than in non cirrhotics. Similarly, liver cirrhosis was more commonly observed in cases of chronic pancreatitis. Conclusion: The frequency of histomorphological changes seen in pancreas and liver was observed considerably among patients giving history of alcohol abuse. The prevalence of co-existence of chronic pancreatitis and liver cirrhosis was 50%.
