Main outcome measures:Temporary or permanent palsy of the recurrent laryngeal nerve, temporary or permanent hypoparathyroidism, recurrence of the goitre, and the incidence of iatrogenic injuries after completion thyroidectomy. Results: Patients were followed up for a median of 14.5 years (range 10-21). After total thyroidectomy 2 patients (3%) developed temporary palsy of the recurrent laryngeal nerve but there were no permanent lesions; and 24 (35%) developed temporary and 2 (3%) permanent hypoparathyroidism. After subtotal thyroidectomy 2 (3%) developed temporary and 1 (1%) permanent palsy of the recurrent laryngeal nerve; and 13 (18%) developed temporary and 1 (1%) permanent hypoparathyroidism. In addition, there were 10 recurrent goitres (14%). After completion thyroidectomy (n = 9) there were 2 cases of temporary and 1 of permanent palsy of the recurrent laryngeal nerve, and 2 cases of temporary and 2 of permanent hypoparathyroidism. Conclusion: Total thyroidectomy is the procedure of choice for the treatment of benign nodular goitre.

An accurate locoregional staging of rectal cancer is essential for the planning of optimal therapy for rectal cancer. Endorectal coil magnetic resonance imaging and transrectal ultrasound showed similar results; the former is more expensive, whereas the latter is operator dependent. At present the use of endorectal coil magnetic resonance imaging seems to be justified only in selected low rectal cancers where transrectal ultrasound yielded doubtful results. However, a more extensive study is necessary to compare the advantages of these diagnostic techniques.

Considering the advantages of MDCT over endoscopy, we propose a new diagnostic algorithm for AGIB.
