Botulinum toxin: an endoscopic approach for treating fecal incontinence.

BACKGROUND AND STUDY AIMS: Fecal incontinence is a common, distressing condition with limited therapeutic options. Botulinum toxin A (BTX-A) injections have been proposed as a treatment for patients with fecal incontinence. This study aimed to determine the short-term clinical outcomes of BTX-A injections in patients with fecal incontinence of varying etiology. PATIENTS AND METHODS: Twenty-six patients with fecal incontinence were enrolled, 17 with their native rectum and 9 with a neo-reservoir following a proctectomy for rectal cancer. BTX-A was endoscopically injected into the rectum/reservoir. Scores for severity (CCS) and quality of life (FIQL) were recorded at baseline and at the 3-month follow-up visit. RESULTS: The CCS was significantly lower after 3 months (median 15, range 4 - 20 vs. 8, range 1 - 19; P = 0.001). The quality of life improved in three of the four FIQL domains. The improvement was maintained in 11 of 12 patients who received more than one injection because of recurrent symptoms. There was no significant predictive factor for the success of BTX-A injections. CONCLUSION: This preliminary study demonstrated that rectal/reservoir injections are an effective short-term treatment for fecal incontinence.

Inflammatory pseudotumor of the cerebellum in a patient with Crohn's disease.

BACKGROUND: Inflammatory pseudotumors are ubiquitous lesions characterized by a polymorphous inflammatory infiltrate containing plasma cells and lymphocytes. In the central nervous system, this pathological condition is rare and the association with Crohn's disease has never been described. CASE DESCRIPTION: A 31-year-old woman with a history of Crohn's disease was referred to our department for progressive headaches and nausea. Neurological examination was normal. Magnetic resonance imaging showed an irregular heterogeneous enhanced mass infiltrating the left cerebellar hemisphere. Total resection was performed and pathological examination led to the conclusion of an inflammatory pseudotumor. CONCLUSION: To our knowledge, this case is the first describing an intra-cerebral inflammatory pseudotumor associated with an inflammatory bowel disease. The diagnosis of an extradigestive location of Crohn's disease was excluded by pathological examination. Although the precise cause of this association remains unknown, it could be hypothesized that the intra-cranial lesion could be the result of the immunosuppressive therapy given for Crohn's disease, or, more likely, could be a part of a systemic dysimmune process.
