Abstract:
Recurrent abdominal pain is defined as at least three episodes of abdominal pain, lasting for three months or more and affecting the daily activities of an individual. Giardiasis is one of the causes of recurrent abdominal pain but is often overlooked. We report the case of an 11-year-old girl who presented with complaints of severe abdominal pain and two episodes of fresh blood in stool in one day. She had recurrent episodes of abdominal pain, occasional bloating, and diarrhea over the past two years. Workup for differentials like appendicitis and ovarian torsion was done. She was initially treated for an ovarian cyst with oral contraceptives, but her symptoms showed no improvement. Therefore, a laparoscopic ovarian cystectomy and appendectomy were attempted. Despite surgical intervention, the abdominal pain failed to resolve. A duodenal biopsy was performed, which showed vegetative growths of Giardia lamblia (G. lamblia). This report highlights the unusual presentation of giardiasis as an acute abdomen, making it a diagnostic challenge.
