RESUMO
OBJECTIVE: Since the first paper published by Matzel et al., in 1995, on the efficacy of sacral nerve stimulation (SNS) in patients with faecal incontinence, the indications, the contraindications, the stimulation technique and follow up of implanted patients have changed. The aim of this article was to provide a consensus opinion on the management of patients with faecal incontinence treated with SNS. METHOD: Recommendations were based on a critical review of the literature when available and on expert opinions in areas with insufficient evidence. RESULTS: We have reviewed the indications and contraindications, proposed an algorithm for patient management showing the place of SNS. The temporary test technique, the implantation technique, the patient follow up and the approach in case of treatment failure were discussed. CONCLUSION: We hope not only to provide a guide on patient management to clinical practitioners interested in SNS but also to harmonize our practices.

To evaluate the features of primary hyperparathyroidism (HPT) with normal serum intact parathyroid hormone (iPTH) levels, we studied 271 consecutive patients undergoing surgery for primary HPT. In 20 patients, serum iPTH levels were within the normal range (10-65 ng/l). In their records, the most common clinical features were fatigue (n=13), polyuria (n=6), renal stone (n=5), and hypertension (n=5). Mean serum calcium and phosphorus were 2.78 and 0.85 mmol/l, respectively: 14 had serum phosphorus within the normal range. Mean serum iPTH was 48.5 ng/l, and was <45 ng/l in nine patients. Cervical ultrasound demonstrated a parathyroid adenoma in nine, and was normal in four. Tc sestamibi parathyroid scintigraphy always demonstrated an adenoma (9/9). In eight patients, normal iPTH values delayed diagnosis. Physicians should be aware of the possibility of HPT in patients with hypercalcaemia, even when serum phosphorus and iPTH levels are within the normal limits. Particularly, HPT cannot be excluded when serum iPTH levels are below the upper part of the normal range. In such cases, cervical imaging, which has the same sensitivity as in other HPT, should be undertaken. These explorations are useful, because many patients are symptomatic and can take advantage of surgery.
