We report a 55-year-old diabetic woman with abdominal pain, pyrexia, and leukocytosis 3 months after aspiration tube placement. Abdominal computed tomography revealed a hypodense mass (10.8 × 7.2 cm) extending into the right anterior abdominal wall. Aspiration of the abscess revealed purulent fluid that grew Streptococcus intermedius. The aspiration tube was removed and 4 endoclips were deployed to close the intragastric stoma. The patient recovered well with 21 days of antibiotics, with resolution of the abscess and full wound healing.
