Summary
Diagnosing retained surgical sponges, often missed on X-rays, is possible with CT and sonography. These imaging techniques reveal characteristic signs of gauze granuloma, enabling correct preoperative diagnosis.
Area of Science:
- Radiology
- Medical Imaging
- Surgical Complications
Background:
- Retained surgical sponges (RSS) are a rare but significant complication following surgical procedures.
- Accurate and timely diagnosis of RSS is crucial to prevent patient morbidity.
Observation:
- Plain abdominal radiographs were normal in all four reported cases of retained surgical sponges.
- Computed tomography (CT) and sonography were utilized for diagnosis in four patients with retained surgical sponges.
Findings:
- CT revealed well-defined, round masses with thick walls, heterogeneous internal densities, calcifications, and gas bubbles in gauze granulomas.
- Sonography demonstrated well-defined hypoechoic masses with echogenic foci and posterior shadowing, indicative of retained foreign bodies.
Implications:
- CT and sonography are valuable tools for diagnosing retained surgical sponges when plain radiographs are inconclusive.
- Combined imaging findings and surgical history allow for accurate preoperative identification of retained foreign bodies.
- Improved diagnostic accuracy for retained surgical sponges can lead to earlier intervention and better patient outcomes.
