Perforation of the Sigmoid Portion in an Adult Patient With Dengue Fever: A Rare Case

Dengue fever can cause gastrointestinal complications, such as intestinal perforation. Pathogenesis is related to mucosal damage leading to ischemia. Diagnosis is through imaging that detects signs of perforation. Treatment is surgical repair of the lesion. A 54-year-old man presented with dengue fever and abdominal pain; abdominal ultrasound showed distension of intestinal loops with wall edema and interloop fluid. Chest radiography produced a finding of pneumoperitoneum. Perforation was suspected, requiring exploratory laparotomy and repair of the lesion. Intestinal perforation due to dengue fever is rare in the literature. It requires high clinical suspicion. Management requires exploratory laparotomy and repair.
