[Sacral nerve stimulation for the treatment of severe fecal incontinence: long-term quality of life and functional outcomes].

BACKGROUND: The aim is to determine whether good functional and quality of life results of sacral nerve stimulation (SNS) in patients with severe fecal incontinence are maintained in the long-term. MATERIAL AND METHODS: Consecutive cohort of patients with severe fecal incontinence not responding to conservative (drugs and/or biofeedback) or surgical (sphincteroplasty) treatment, undergoing SNS between 2002 and 2013. Patients with a definitive implant were individually assessed in consultation throughout the follow-up, until January 2016. Defeca-tory function was assessed by Wexner score and stool diary, and perceived quality of life by FIQL and EQ-5D question-naires. RESULTS: Acute percutaneous nerve evaluation (PNE) was performed on 93 patients; a temporary electrode was implanted in 91 (79.1% women, mean age 62.5 years), obtaining a good functional response in 64. A permanent implant was per-formed in 61 patients, with a mean follow-up of 78.1 months (SD: 35.4; range 1-161); at the end of the study 42 patients remained in follow-up. A significant decrease was observed in the number of days per week with an incontinent episode, from 4.98 (SD 2.1) to 1.25 (SD 1.7), and in Wexner score from 16.88 (SD 2.74) to 6.95 (SD 3.54). Specific FIQL and generic EQ-5D questionnaires showed a significant improvement in quality of life. CONCLUSION: Long-term functional and quality of life outcomes of SNS for the treatment of severe faecal incontinence is maintained, with individual follow-ups that reach 10 years.

[Cutaneous metastases of rectal cancer]. / Metástasis cutáneas de cáncer de recto.

Colorectal carcinoma is a tumour that very infrequently gives rise to cutaneous metastases and when it does so, it is rarely via the haematogenous route. We present the case of a 55-year old male diagnosed with an adenocarcinoma of the rectum (lower third), clinical stage T3N2M0. Initially treated with neoadjuvant radiochemotherapy, he was operated on eight weeks later, with an extended abdominoperineal amputation. The anatomopathological result was mucinous adenocarcinoma of the rectum, clinical stage ypT3bN1. Following a postoperative period without complications, the patient received chemotherapeutic treatment with capecitabine. Eighteen months later the patient reported the progressive appearance of subcutaneous nodules in different localizations. In the computerized tomography test multiple images were objectivized suggesting metastasis at the hepatic and pulmonary levels, as well as subcutaneous lesions. The biopsy-excision of one of the subcutaneous nodules corroborated the suspicion of metastasis of the adenocarcinoma of the rectum. Chemotherapy treatment was considered for the patient, which was not administered due to the rapid deterioration of the patient leading to his death.
