Abstract
Background: Typhoid fever is a systemic infectious disease specific to human beings which is caused by a gram-negative bacillus (Salmonella typhi). Its incidence demonstrates significant variations in different regions of the world. It is generally seen in children of the school age. In developing countries, its most widely seen, and serious complication is intestinal perforation (IP). IP is generally seen within the third week of the disease. In children, it can onset with necrotic ileal Peyer’s patches which progress to diffuse peritonitis if not treated with appropriate medical therapy or in cases of delayed diagnosis. In these conditions, it requires surgical treatment . Despite novel antibiotics, and improvements in surgical techniques, mortality rates still range between 9, and 22 percent.
Conclusion: This case report aims to distract attention to the importance of appropriate, and timely surgical intervention in a 15-year-old boy who presented with terminal ileum perforation developed secondary to inappropriately treated typhoid fever.
