Dengue Infections and the Surgical Patient.

Dengue infections are increasing globally and account for significant morbidity and mortality. Severe dengue results in microvascular changes and coagulopathy that may make surgical intervention risky and the overall surgical management challenging. We outline the potential surgical manifestations and complications following dengue infections and describe the clinical, pathogenetic, diagnostic, and treatment aspects of dengue and surgical patients. The main surgical presentations were acute cholecystitis, acute pancreatitis, acute appendicitis, splenic rupture, bowel perforation, gastrointestinal bleeding, and hematomas. Dengue may also mimic an acute abdomen without any true surgical complications. A majority were treated nonoperatively. Misdiagnosis and unnecessary surgical intervention resulted in poor outcomes. Better knowledge of the potential surgical complications would help in early diagnosis, treatment, and referral to specialized centers and thus improve outcomes. A high degree of suspicion of dengue fever is necessary when patients in a dengue-epidemic area present with acute abdomen or bleeding manifestations. In endemic areas, early dengue antigen testing and abdominal imaging before surgical intervention may help in the diagnoses. Multidisciplinary team involvement with case-by-case decision-making is needed for optimal care.
