Summary
Plain abdominal X-rays remain highly sensitive for diagnosing intra-abdominal abscesses post-surgery. While CT and US offer better imaging for interventions, X-rays are still valuable for initial detection.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Radiology
Background:
- Abdominal abscesses are a serious complication of laparotomy, particularly after surgery for abdominal neoplasias.
- These abscesses are associated with a high mortality rate, necessitating effective diagnostic and therapeutic strategies.
Purpose of the Study:
- To review diagnostic and therapeutic procedures for intra-abdominal abscesses in patients who underwent surgery for abdominal neoplasias.
- To evaluate the diagnostic accuracy of plain abdominal films compared to CT and US, and the efficacy of interventional radiology.
Main Methods:
- Retrospective review of 36 patients with intra-abdominal abscesses post-abdominal neoplasia surgery.
- Diagnostic imaging included plain films of the abdomen and chest, CT, and US.
- Interventional radiology procedures involved fine-needle aspiration and catheter drainage.
Main Results:
- Initial diagnostic procedures (plain film, CT, US) had a sensitivity of 78%.
- Fine-needle aspiration and catheter drainage were performed in 69.5% of patients.
- Fine-needle aspiration achieved complete abscess evacuation in 16%, while catheter drainage was successful in 84%.
Conclusions:
- Plain abdominal X-rays demonstrate high sensitivity and specificity for intra-abdominal abscesses.
- Despite CT and US being preferred for imaging guidance, plain films remain a valuable initial diagnostic tool.
- Interventional radiology, particularly catheter drainage, is effective in managing these post-surgical abscesses.
