Rectalepidural fistula complicating Crohn's enterocolitis

Spinal epidural abscess: a rare complication of ulcerative colitis after ileal pouch anal anastomosis

Background

Spinal epidural abscess is a rare condition with high morbidity and mortality, for which a delay in diagnosis and treatment can lead to irreversible neurologic deficit or even death. Although patients with spinal epidural abscess have systemic predisposing immunocompromised conditions, spinal intervention, or trauma, this condition has been reported as a result of perforation or fistulization arising from inflammatory bowel disease. We describe herein a rare case of spinal epidural abscess as a complication of ileal pouch anal anastomosis.

Case presentation

A 37-year-old man who had previously undergone restorative proctocolectomy and ileal pouch anal anastomosis for ulcerative colitis presented with complaints of persistent low-grade fever and lumbago with unusual sensation in the lower legs. After evaluation by Gastrografin contrast radiography, computed tomography, and magnetic resonance imaging, he was diagnosed with a spinal epidural abscess extending from L5 to S1. In addition, the abscess communicated with the ileal pouch. He underwent surgical drainage of the abscess, excision of the fistula, and defunctioning ileostomy. Although a second operation for drainage was required for residual presacral abscess, there was no sign of recurrence of the spinal epidural abscess. He eventually was able to close his stoma.

Conclusions

Although spinal epidural abscess is a rare complication, one should take this condition into account when patients complain of back pain or neurologic symptoms of the lower extremities, given the possibility of fistulous communication between the ileal pouch and spine.

[Pneumorachis: report of three rare causes]

The presence of gas in the spinal canal or pneumorachis is a rare imaging finding, typically incidental. Pneumorachis may be due to several degenerative, traumatic, infectious, tumoral or iatrogenic etiologies. We report three cases of pneumorachis in patients with lumbar back pain. A case occurred in a patient with advanced degenerative disk disease. Another was in a patient with posterior facet synovial cyst. The last was in a patient with locally advanced rectal carcinoma complicated by perforation. Pneumorachis was detected on MRI in two cases and on CT in all three cases.

Spinal epidural abscess -- a rare complication of inflammatory bowel disease

Spinal epidural abscess is an uncommon but highly morbid illness. While it usually afflicts older, immunocompromised patients, this condition has been reported as a result of intestinal perforation in the setting of inflammatory bowel disease. Two cases of spinal epidural abscess in patients with inflammatory bowel disease are reported: one in a patient with Crohn's disease and one in a patient with ulcerative colitis after restorative proctocolectomy.

Diagnosis and results of different treatment regimens in patients with spinal abscesses

Bacterial abscesses involving the spinal canal are associated with a high morbidity and mortality. Most frequently, these lesions are found in the epidural, rarely in the subdural space. In this report, our clinical material consists of a series of 16 patients treated during the last seven years. The clinical presentation included local neurological signs (back pain, para-/tetraparesis, bladder dysfunction), disturbances of consciousness (ranging from drowsiness to deep coma) and general inflammatory signs (meningism, fever). All patients presented with risk factors (septic foci, chronic diseases, and iatrogenic causes). Laboratory investigations revealed typically pathological blood sedimentation rate, leucocytosis and CSF-pleocytosis. Radiologically, the diagnosis was confirmed by myelography, CT and preferably MRI. The abscesses were located epidurally in 14 and subdurally in 2 cases. The surgical treatment included laminectomy, or multiple flavectomies in extensive lesions. Drainage systems (either simple silicon outflow drains or suction-/irrigation systems) were installed in all cases, as well as antibiotic treatment. Results of treatment: Following an observation period of 0.5-6 years, we found complete recovery in six (38%) cases, six (38%) others were mildly disabled and four (25%) patients died. Focussing on the results of the two different drainage systems, we found a statistically significant superiority of the inflow-/outflow system. Complications included mandatory re-exploration, post-inflammatory hydrocephalus, syringomyelia, spinal instability, surgical treatment of peripheral septic foci and therapy resistant septicaemia. In conclusion, we propose that spinal epi- or subdural abscesses require surgical evacuation, using a suction-/irrigation drainage system, as well as antibiotic and intensive care treatment.
