Abstract:
A 30 year old man presented with an initial clinical picture limited to low back pain. Increasing severity of the pain after one month led to his admission to a surgical department and the diagnosis of a large right retroperitoneal abscess. Several hours before the proposed operation for extraperitoneal surgical drainage of the abscess through a lumbar approach, his condition was complicated by the intraperitoneal rupture of the abscess. The resulting peritonitis and the retroperitoneal abscess were treated through a laparotomy and the postoperative course was uncomplicated. A literature review showed this to be only the second case of this rare generalized peritonitis complication to be reported, for which a parallel can be drawn with the intraperitoneal rupture of a pyonephrosis. A general overview of retroperitoneal abscesses is presented.
Insights
A retroperitoneal abscess in a 30-year-old man unexpectedly ruptured, causing generalized peritonitis. This rare complication required immediate surgical intervention via laparotomy, with an uncomplicated recovery.
Area of Science:
- Surgical Case Report
- Abdominal Surgery
- Infectious Disease
Background:
- Retroperitoneal abscesses are collections of pus in the space behind the abdominal lining.
- They can present with non-specific symptoms such as low back pain.
- Early diagnosis and management are crucial to prevent complications.
Observation:
- A 30-year-old male presented with worsening low back pain.
- Imaging revealed a large right retroperitoneal abscess.
- The abscess spontaneously ruptured into the peritoneal cavity prior to planned surgical drainage.
Findings:
- The patient developed generalized peritonitis secondary to the abscess rupture.
- Emergency laparotomy was performed for source control and peritoneal lavage.
- The postoperative course was uneventful, with complete recovery.
Implications:
- Intraperitoneal rupture of a retroperitoneal abscess is a rare but life-threatening complication.
- This case highlights the importance of considering abscess rupture in patients with peritonitis.
- Prompt surgical management is essential for favorable outcomes in such critical conditions.
