Epidemiological Characteristics, Spectrum of Upper Gastrointestinal Tract Injuries and Burden of Corrosive Intake Patients in A Tertiary Care Hospital in Islamabad

Objective: To investigate the epidemiology and spectrum of upper gastrointestinal (UGI) tract injuries, as well as to assess the burden of Corrosive intake patients who presented to an Islamabad tertiary care hospital.Study Design: Descriptive cross-sectional.Place and Duration of Study: The study was carried out at the Department of Gastroenterology of Pakistan Institute of Medical Sciences, Islamabad, Pakistan from January 2021 to December 2021.Materials and Methods: A retrospective descriptive study was carried out at the department of Gastroenterology using patient records. After taking a thorough history, patients were admitted in the hospital, which was followed by a physical examination, necessary investigations, and an initial emergency management. The study did not include any follow-up cases. Corrosive ingestion induced tissue damage was assessed via endoscopy using Zargar’s classification. The data was analyzed using SPSS version 26.Results: The total number of patients who were brought to emergency department with corrosive ingestion during one year were 74. There were 45 females (60.81%) and 29 male patients (39.19%). Age ranged from 13 to 60 years (mean 27.01 ± 18.91) with highest incidence in the age group of 21-30 years which was 44.59 % followed by 11-20 age Group (28.28 %). 41 patients were unmarried (55.41%), whereas 33 were married (44.59 %). Corrosive ingestion was most common in illiterate patients (44.59 %). 46 patients (62.16%) confessed that they ingested corrosive substance intentionally while 28 (37.84 %) claimed it happened due to accidental ingestion. Washroom cleaner was found to be the most commonly used corrosive Agent (90.54%). The most common sites that sustained corrosive injuries were the oropharynx and oesophagus, while the duodenum was found to be the least affected with normal endoscopic examination in the majority of the patients (51.35 %).Conclusion: In developing countries, corrosive ingestion is a major public health concern, with a high proportion of suicidal ingestions. It is particularly common in suicidal young people with easy access to washroom cleaners. The seriousness of this problem emphasises the importance of pursuing multidisciplinary solutions. In addition, strict action and stringent legislation by governing bodies are required in developing countries to limit adults' unrestricted access to hazardous corrosive elements.
