Abstract: AIM: To review and to update the management protocols in thyroid surgery proposed two years ago by 1st Consensus Conference called on the topic by the Italian Association of Endocrine Surgery Units (UEC Club). METHOD: The 2nd Consensus Conference took place November 30, 2008 in Pisa within the framework of the 7th National Congress of the UEC Club. A selected board of endocrinologists and endocrine surgeons (chairmans: Paolo Miccoli and Aldo Pinchera; speaker: Lodovico Rosato) examined the individual chapters and submitted the consensus text for the approval of several experts. This plain and concise text provides the rationale of the thyroid patient management and wants to be the most complete possible tool for the physicians and other professionals in the field. CONCLUSIONS: The diagnostic, therapeutic and healthcare management protocols in thyroid surgery approved by the 2nd Consensus Conference are officially those proposed by the Italian Association of Endocrine Surgery Units (UEC Club) and are subject to review by two years.

Abstract: BACKGROUND: Thyroid surgery presents a low incidence of complications. Death is certainly a rare, or even exceptional event. Hypoparathyroidism, above all if definitive, is the main complication of total thyroidectomy with percentages that very between 0 and 10% in the literature (average 2%). METHODS: The incidence of recurrent lesions varies between an improbable 0% to 8%, whereas lesions to the superior laryngeal nerve are relatively frequent, but often undervalued. Dysphagia, although always transient, presents a high risk of pneumonia ab ingestis and severe dehydration. Hemorrhage has an incidence of 0.1-3.8% and infection is reported in approximately 1% of cases. The permanent and recurrence nature of thyroid pathology in literature is between 5 and 11%, resulting from inadequate or sometimes useless surgery. Hypothyroidism is the logical consequence of total thyroidectomy. In the light of these data we have re-examined 300 operations involving thyroid pathology performed by the same team using the same method over the past 4 years (82% females, 18% males). 33% of the cases presented benign euthyroid nodular pathology, 27% hyperfunctioning benign nodular pathology, 2.6% Flajani-Basedow-Graves disease, 9% were adenomas, 7% were differentiated carcinomas, 2% anaplastic carcinomas and 0.7% medullary carcinomas. 99 extracapsular total loboisthmectomies, 135 total extracapsular thyroidectomies and 66 subtotal thyroidectomies were performed. RESULTS: The following complications were observed: 31/300 symptomatic hypocalcemias of which 25 were transient and 6 (2%) were definitive but easily controlled with treatment; 9 recurrent monoplegias out of 501 isolated recurrent forms of which 4 (0.8%) was permanent; 5/300 (1.7%) postoperative dysphagias associated with recurrent monoplegia in 4 cases. Damage to the external branch of the superior laryngeal nerve was suspected in 11/300 cases (3.7%). Postoperative hemorrhage occurred with an incidence of 1.3%, whereas the incidence of wound infection and serous collection was 1.7%. Moreover, persistent hyperthyroidism after subtotal bilateral thyroidectomy was observed secondary to toxic plurinodular struma. A case of paralysis of the right ulnar nerve, when the arm was adducted, was observed on the operating table, but regressed after about 4 months. Mortality was zero. CONCLUSIONS: Thyroid surgery is still hampered by a relatively low percentage of complications, which are probably still the result of various technical limitations, and it appears difficult to reduce these, let alone eliminate them completely.

Abstract: BACKGROUND: Intrathyroid metastases (ITM) are rare and usually have a dismal prognosis. The aim of this study was to detect which neoplasms metastasize most often to the thyroid gland, their clinical features and treatment options. MATERIALS AND METHODS: Retrospective analysis of clinical files of 17,122 patients submitted to surgery for thyroid disease between 1995 and 2005. Twenty-five patients (median age 61 years) were affected by ITM. RESULTS: The site of the primary tumor was: kidney (15), lung (4), colon (3), breast (1), melanoma (1), and unknown in 1 patient. Ten patients (40%) complained of preoperative symptoms, in the others, thyroid involvement was incidentally discovered during the follow-up for the primary cancer. Twenty patients (80%) underwent total thyroidectomy, 3 received thyroid lobectomy and 2 palliative procedures. Morbidity was 16%, mortality was nil. The median follow-up was 24 months. CONCLUSION: ITM should always be suspected in any patient with a previous history of malignancy. Fine-needle agobiopsy (FNAB) with immunohistochemical stains may help in preoperative workup. A long delay between the primary tumor and the recurrence warrants surgery and total thyroidectomy seems to be the treatment of choice because of the multifocality of metastasis to the thyroid gland.

Abstract: Unilateral phrenic nerve paralysis is a rare complication of cervico-mediastinal goitre. It occurs when adhesions grow between the intrathoracic part of the thyroid and the nerve, specially where the goitre enters the mediastinum behind the first rib. The damage may be caused by strain of the nerve due to the descent of the goitre into the chest or may be caused by the surgical manoeuvres during thyroidectomy performed by cervical approach. Two patients operated on for large cervico-mediastinal goitre are reported: a 70-year-old male with a large intrathoracic growth of the left thyroid lobe and a 54-year-old male with a large intrathoracic growth to the right lobe. A few days after total thyroidectomy they showed signs of exertional dyspnoea. The exams performed showed hemi-diaphragm relaxatio due to phrenic nerve paralysis, with resulting reduction of respiratory space. Phrenic nerve paralysis may follow total thyroidectomy for large cervico-mediastinal goitres; is not due to the operative technique, but rather to the particular anatomic conditions which may be found.

Abstract: BACKGROUND: We compared the surgical outcomes in patients undergoing bilateral thyroid surgery with or without parathyroid gland autotransplantation (PTAT). METHODS: One thousand three hundred nine patients underwent surgery for treatment of various thyroid diseases at three Academic Departments of General Surgery and one Endocrine-Surgical Unit throughout Italy. A nonviable gland or difficulties in dissection of the parathyroid glands were encountered in 160 (13.7%) patients. The subjects were divided into two groups: (1) patients undergoing PTAT during thyroidectomy (n = 79) versus (2) control group (n = 81), patients not undergoing PTAT. RESULTS: Clinical manifestations occurred in 5.0% of PTAT patients and in 13.6% of control patients (P = NS). Total postoperative hypocalcemia was less among PTAT than control patients (17.7% and 48.1%, respectively; P = .0001). There was no significant difference between the two groups in terms of definitive hypocalcemia (0% vs 2.5% in PTAT and control, respectively). Transient postoperative hypocalcemia was less among PTAT than controls (17.7% vs 45.7%; P = .0002). PTAT was associated with decreased occurrence of hypocalcemia in the two subgroups of patients operated for benign euthyroid disease (P < .0001), as compared with the control group. CONCLUSIONS: PTAT is an effective procedure to reduce the incidence of permanent hypoparathyroidism. Transient hypoparathyroidism appears to not be influenced by PTAT. Moreover, we observed that damage to one parathyroid gland has more side effects (ie, transient hypocalcemia) among patients who were preoperatively at low rather than at high risk of postoperative hypocalcemia.

Abstract: The aim of the study was to draw up a management protocol in thyroid surgery promoted by the Italian Association of Endocrine Surgery Units (Club delle UEC), shared by the experts and applied by the operators in the sector. The management protocols already presented in February 2002 and drawn up by the first Author of the present publication on the occasion of the current review were examined by the I Consensus Conference called on the topic by the Italian Endocrine Surgery Units. The conference comprised two distinct sessions, the first on 18 June 2005 within the framework of the 4th National Congress of the Club delle UEC in Naples, and the second on 17 September 2005 within the framework of the 8th Multidisciplinary Scanno Prize Meeting. A selected board of endocrinologists and endocrine surgeons, chaired by Aldo Pinchera and comprising the first nine Authors of this paper, examined the individual chapters in close collaboration with the other Authors, comparing their findings with the opinions of the experts cited in the text and submitting the consensus text for the approval of all those present. The diagnostic, therapeutic and healtcare management protocols in thyroid surgery approved by the I Consensus Conference are officially those proposed by the Italian Association of Endocrine Surgery Units (Club delle UEC) and are subject to review by October 1, 2007.

Abstract: Complication rates associated with thyroid surgery can be evaluated only through analysis of case studies and follow-up data. This study covers postoperative data from 14,934 patients subjected to a follow-up of 5 years. Among them, 3130 (20.9%) underwent total lobectomy (TL), 9599 (64.3%) total thyroidectomy (TT), 1448 (9.7%) subtotal thyroidectomy with a monolateral remnant (MRST), and 757 (5.1%) subtotal thyroidectomy with bilateral remnants (BRST). A total of 6% of the patients had already been operated on. Persistent hypoparathyroidism occurred after 1.7% of all the operations, and temporary hypoparathyroidism was noted in 8.3%. Permanent palsy of the laryngeal recurrent nerve (LRN) occurred in 1.0% of patients, transient palsy in 2.0%, and diplegia in 0.4%. The superior laryngeal nerve was damaged in 3.7%; dysphagia occurred in 1.4% of cases, hemorrhage in 1.2%, and wound infection in 0.3%. No deaths were reported. A significant rate of LRN damage was noted, which has an important impact on the patient's social life. Hypoparathyroidism after total thyroidectomy is an important complication that can be successfully treated by therapy, although it is not always easily managed in special circumstances such as in young persons or pregnant women. The complications associated with thyroid surgery must be kept in mind so the surgeon can carefully evaluate the surgical and medical therapeutic options, have more precise surgical indications, and be able to give the patient adequate information.

Abstract: The range of indications for total thyroidectomy in the treatment of thyroid disease is steadily increasing, but any attempt to assess its real efficacy necessarily calls for a knowledge of the incidence of complications, amongst other things in order to provide the patient with complete information regarding the operation before obtaining his or her consent. Retrospective and observational analysis of 14,934 thyroidectomies performed in 42 Endocrine Surgery Units in Italy has made it possible to compare total thyroidectomy (TT) versus subtotal thyroidectomy with a bilateral remnant (ST-BR), subtotal thyroidectomy with a unilateral remnant (ST-UR) and total lobectomy-isthmectomy (TLI). The correlation between the number of total thyroidectomies and each of the other surgical procedures and the number of complications occurring with each of them was also assessed in order to quantify the effective risk of complications by determining the Odds Ratios on the basis of univariate analysis of the variables considered. The cases reviewed consisted of 9,599 TT (64%), 3,130 TLI (21%), 1,448 ST-UR (22%) and 757 ST-BR (5%); 13,023 (87%) cases were suffering from benign disease and 1,911 (13%) from malignancies. Recurrent laryngeal nerve injuries were present in 4.3% of the TT cases with 2.4% transient and 1.3% definitive (as against 3% in ST-BR and 2% in ST-UR with 1.4% and 1.1% transient, and 1% and 0.6% definitive, respectively; and 1.4% transient and 0.6% definitive in TLI). Hypocalcaemia after TT was transient in 14% and definitive in 2.2% (as against transient rates of 5% in ST-BR and ST-UR and 0.4 in TLI; and definitive hypocalcaemia in 0.6%, 0.8% and 0.07%, respectively). Haemorrhage occurred in 1.6% of TT cases (as against 2.1%, 0.5% and 0.4% in ST-BR, ST-UR and TLI, respectively). The Odds Ratios showed that TT presented a 16% higher complication rate than ST-UR which was assigned a value of 1, a 3% higher rate than ST-BR and a 5% lower rate than TLI. This greater incidence of complications with TT is attributable mainly to the greater incidence of transient hypoglycaemia and to a lesser extent to the slightly higher incidence of definitive hypoglycaemia, whereas the incidences of recurrent laryngeal nerve injuries were very similar in TT and ST-BR. Haemorrhagic complications were more frequent in ST-BR than in TT. Bearing in mind that TT is the absolute indication in the more demanding thyroid diseases (tumours, retrosternal goitre, Basedow's disease, recurrences) and in view of its fairly low complication rate, we believe that TT is a safe, reliable procedure, provided it is performed in a technically scrupulous manner. ST-BR is a technique which should be abandoned owing to the fact that its complication rate is comparable to that of TT and to the recurrences it may give rise to. ST-UR may be indicated if the surgeon is not sure of safeguarding the anatomical integrity of the recurrent nerve on one side.
