Abstract

Background and aims: Previous large studies on the epidemiology and clinical profile of chronic pancreatitis have suggested significant differences in presentation and management in the eastern and western hemispheres. The aim of this systematic review was to compare large multicenter studies across different geographic regions of the world to detect meaningful differences in the presentation and management of this poorly understood disease.

Methods: We identified 237 manuscripts through a comprehensive literature review aiming to identify multicenter studies enrolling more than 200 patients to limit reporting biases. After rigorous screening, 12 studies were included for the final analysis. The Asian studies were included in the eastern cohort, and the European and American studies were included in the western cohort. Reported demographics, risk factors, etiologies, clinical presentation, complications, and management strategies were then compared.

Results: We found similar demographics across both cohorts including age, prevalence among gender, and predominant etiology. Clinical manifestations including pain, pancreatic calcifications, and diabetes were similar between both cohorts although pseudocysts, pancreatic cancer, and strictures were more common in the west. Notably opioids and surgical/endotherapy management were more common in the west as well.

Conclusion: Chronic pancreatitis is a protracted disease affecting predominantly middle-aged people, leading to a decreased quality of life. Chronic pancreatitis now appears to have a fairly similar clinical profile and natural history in the east and west. There is notable variability in management. We hope that international collaboration may identify common targets for research which could lead to significant advances in the understanding and management of chronic pancreatitis.
