Retroperitoneal abscess after urgent resection of the stomach in a geriatric patient treated with a surgical extraperitoneal approach - case report.

Retroperitoneal abscess after abdominal and retroperitoneal surgery is a relatively rare but serious complication that most often occurs as a result of a healing disorder in the postoperative period. The incidence is not high, in the literature the cases are mostly reported as case reports with a serious clinical course, high morbidity and mortality. The most important factor of effective treatment, after successful diagnosis by CT examination is rapid evacuation of the abscess and retroperitoneal drainage, in which mini-invasive surgical or radiological drainage dominate as methods of choice. Surgical drainage, burdened by higher morbidity and mortality is considered the last resort after failure of mini-invasive methods. In our case report, we present a case of retroperitoneal abscess, arising as a complication after gastric resection, which was evacuated and drained primarily surgically due to unsuitability for radiological intervention.
