Vertebral discitis after laparoscopic resection rectopexy: a rare differential diagnosis

Vertebral discitis usually arises from haematogenous spread of pathogens to the discs and bones. Vertebral discitis can rarely occur as a complication after laparoscopic operations with fixating sutures on the promontory. We report the case of an 81-year-old woman who underwent a laparoscopic resection rectopexy because of rectal prolapse. Weeks after the operation, the patient developed lower back pain with radiation to both legs not responding to symptomatic therapy. Two months later, a magnetic resonance imaging of the lumbar spine showed vertebral osteomyelitis and discitis. A fixation on the promontory may be sufficiently traumatic to the spine to pave the way for subsequent infection. A high index of suspicion should be raised in patients with persistent, severe back pain. Anamnesis, imageing and an adequate specimen from the affected area for microbiological analysis are crucial for timely diagnosis and appropriate management involving targeted and prolonged antimicrobial therapy.
