[First case of sacral neuromodulation for treatment of urinary and fecal incontinence in Mexico. Case report.]. / Primer caso de neuromodulación sacrapara el tratamiento de la incontinenciaurinaria y fecal en México. Informe de caso.

Sacral neuromodulation is a new treatment for urinary and fecal incontinence that has demonstrated good therapeutic results. This treatment modality has shown not only to reduce urinary dysfunction symptoms and urinary and fecal incontinence but improve quality of life scores as well. We present a 73 years old female patient with severe fecal and urinary incontinence with major quality of life impact. She was referred after failure of different surgical and conservative therapeutic approaches. Her evaluation met inclusion criteria for sacral neuromodulation treatment. Acute sacral nerve evaluation (PNE) proved to be therapeutic in the patient as measured by at least a 50 percent improvement in her symptoms so a permanent implant (Medtronic InterStim System) was placed. After the implant there was a significant improvement in urinary and fecal functional scores. Fecal Incontinence Severity Index improved from 34 to 8 and Urinary Sandvik's Severity Index from very severe urinary incontinence to minor urinary incontinence after the placement of the implant. Using standard quality of life questionnaires, she improved in the areas of lifestyle,coping and behavior and her experience with depression and self-perception.

[Fistulotomy vs fistulectomy. Ultrasonographic evaluation of lesion of the anal sphincter function]. / Fistulotomía vs fistulectomía. Valoración ultrasonográfica de lesión al mecanismo de esfínter anal.

OBJECTIVE: To determine the extension of the lesion implicated on the mechanism of the anal sphincter with endoanal ultrasound in patients with simple fistulae, managed with fistulotomy versus fistulectomy. SITE: Central Military Hospital. Colon and Rectum Service. DESIGN OF STUDY: A prospective, comparative, descriptive and longitudinal study was performed. METHODS: A total of 40 patients with anal simple fistula were studied from march 1997 to march 1998. They were divided in two randomized groups: group A (n = 20) patients treated with fistulectomy, and group B (n = 20) patients managed with fistulotomy. Endoanal ultrasound was practice at the time of the diagnosis and six weeks later to identify integrity of both internal and external anal sphincter, and to register them in separate form. RESULTS: There were no significant differences in sex and age distribution, nor in type of fistula. The average of internal anal sphincter lesion in inter-sphincteric fistulae treated with fistulotomy was 8.5 mm versus 9.08 with fistulectomy (p > 0.05). The average of internal and external anal sphincter lesion in trans-sphincteric fistulae managed with fistulotomy was 9.25 mm versus 11.38 with fistulectomy (p < 0.05). The global analysis showed that the average of the lesion in the sphincter, mechanism was larger in the fistulectomy versus fistulotomy (p < 0.05). CONCLUSION: The major muscular injury made to the sphincter mechanism is caused mainly by the fistulectomy in comparison with the conventional fistulotomy.
