A case of pelvic abscess treated using endoscopic ultrasound-guided transrectal drainage

Abstract

A 71-year-old woman receiving long-term oral steroids for treatment of Vogt-Koyanagi-Harada disease was admitted to our hospital with symptoms of fever, vomiting, diarrhea, and lower abdominal pain. A diagnosis of peritonitis caused by infectious gastroenteritis was made. Following treatment with fasting, antibiotics, and intravenous fluids, her symptoms, physical findings, and laboratory results improved. However, after cessation of antibiotic treatment, her fever returned and laboratory results indicated increased inflammation. A pelvic abscess was observed using computed tomography (CT) . It was located adjacent to the rectum as observed using endoscopic ultrasonography. Endoscopic ultrasound-guided fine-needle aspiration was performed through the rectum wall and two internal stents were inserted. Her symptoms subsequently improved and a follow-up CT scan showed the abscess had significantly decreased in size.
