Digestive and Liver Disease Statistics in Iran

Abstract

Background

Gastrointestinal and liver diseases (GILD) are among the most common causes of morbidity in Iran and constitute a substantial proportion of mortality which imposes enormous economic consequences. Our purpose is to collect information and report current statistics on physician visits, hospitalizations, and deaths due to common GILD in Iran.

Methods

Data on the leading causes of death were obtained from the Iranian Ministry of Health, Office of Health Statistics. A total of 213,322 deaths were reported from March 2003 to February 2004 (excluding mortality from the Bam earthquake) which equaled 4.4 deaths per 1000 population. Of these, 36,575 were due to accidents. Causes of death were reported on the basis of the 10th revision of the International Classification of Diseases (ICD-10; 1992). The leading causes of hospitalization were obtained from the database of the GILD ward in Shariati Hospital, one of the largest and best known gastroenterology referral hospitals in Iran. Similarly, leading causes of out-patient referrals were identified from a large multi-physician outpatient clinic in Tehran.

Results

The five leading gastrointestinal causes of death in order of frequency were: gastric cancer, hepatobiliary cancer, liver cirrhosis, esophageal cancer, and colorectal cancer. The five leading causes of hospitalization in the GILD ward of Shariati Hospital were: liver cirrhosis, hepatitis,

peptic ulcer disease, cholycystitis and cholangitis, and colorectal cancer. The most common outpatient diagnosis was gastroesophageal reflux disease followed by irritable bowel syndrome (IBS), duodenal ulcer (DU), non-ulcer dyspepsia, and chronic hepatitis B (HBV).

Conclusion

Gastrointestinal and liver malignancy along with chronic liver disease constitute the main GILD reasons for hospitalization and deaths in Iran. Gastroesophageal reflux disease, IBS, and chronic HBV are the most common GILD outpatient diagnoses.
