Total thyroidectomy. The indications and results of 630 cases 总被引:2,自引:0,他引:2
Over the past twenty years, 630 total thyroidectomies have been performed: 121 (101 females, 20 males) for Grave's disease; 113 (81 females, 32 males) for cold thyroid nodules and head, neck, and thorax irradiation during childhood; and 396 (317 females, 70 males) for a cold dominant nodule of the thyroid. One hundred eighty-three patients had papillary follicular carcinoma, four had medullary carcinoma, five had anaplastic or small cell carcinoma, and one had reticulum cell sarcoma. In this series, patients with Grave's disease had a 5 per cent malignancy rate. Those who had had radiation to the head and neck and thorax during childhood had a 42.5 per cent malignancy rate, and those with a cold dominant thyroid nodule had a 35 per cent malignancy rate. A comparison of the complications and sequelae of total thyroidectomy to those of subtotal thyroidectomy revealed that they were essentially the same. However, the multifold risk of complications in a second neck exploration, plus the anesthetic risk and the time delay when further surgery was then needed after a subtotal procedure, are completely avoided by performing total thyroidectomy primarily. Thus, when surgery is indicated for the management of Grave's disease, thyroid nodules and childhood irradiation, and cold dominant nodules of the thyroid suspected of carcinoma, it is our contention and recommendation that total thyroidectomy be performed. 相似文献

The management of an "isofunctioning" thyroid nodule--defined by radioiodine uptake equivalent to normal thyroid tissue--is often a dilemma. Our goal was to determine the percentage of thyroid nodules that were isofunctioning and the frequency with which carcinoma occurred in an isofunctioning nodule. Patients referred for evaluation of a thyroid nodule from 1990 to 2002 were reviewed and those with an iodine-123 thyroid scintiscan were identified. Nodule size, serum thyrotropin, fine-needle aspiration biopsy, pathology, and follow-up were determined for patients with an isofunctioning, hypofunctioning, or hyperfunctioning thyroid nodule. Of the 562 patients with a thyroid nodule 273 (49%) had a thyroid scan. Nodules were hypofunctioning in 232 (85%), isofunctioning in 29 (11%), and hyperfunctioning in 12 (4%) patients. Mean nodule size and serum thyrotropin level were respectively 2.49 +/- 0.23 cm and 1.73 +/- 0.26 microIU/mL for isofunctioning, 2.47 +/- 0.31 cm and 0.83 +/- 0.21 microIU/mL for hyperfunctioning, and 3.94 +/- 0.13 cm and 1.86 +/- 0.28 pIU/mL for hypofunctioning nodules. Seventeen patients with an isofunctioning nodule underwent thyroidectomy and 12 patients were followed for a mean 27 months without an increase in nodule size. No patient with a hyperfunctioning nodule, six patients (21%) with an isofunctioning nodule, and 44 patients (19%) with a hypofunctioning nodule had a carcinoma. We conclude that the risk of malignancy in an isofunctioning nodule is similar to that of a hypofunctioning nodule and therefore the management should be based on routine fine-needle aspiration biopsy. 相似文献

Background Certain ultrasound features can predict malignancy in patients with thyroid nodules. The purpose of this study was to determine
the value of surgeon-performed ultrasound (SUS) in predicting thyroid malignancy in patients with indeterminate fine-needle
aspiration (FNA) cytology.
Methods 477 consecutive patients with dominant thyroid nodules were referred to our institution from 2002 to 2007. Of these, 180/477(38%)
were judged to have indeterminate cytology: follicular neoplasm (FN, n = 108), Hürthle neoplasm (HN, n = 29), and suspicious for papillary thyroid cancer (SPTC, n = 43). SUS characteristics for thyroid nodules were recorded in a prospective database prior to thyroidectomy. Variables
analyzed included patients’ age and sex, nodule size, shape, echogenicity, consistency, borders, multiplicity/multicentricity,
and presence of microcalcifications. SUS features of thyroid nodules were correlated with final pathology. The accuracy of
individual SUS features as well as the presence of two or more adverse features in predicting malignancy was also examined.
Results There were 144 females and 36 males. Mean age was 52 years (range 17–87 years). Mean tumor size was 2.7 cm (range 0.65–6.6 cm).
Overall, final pathology revealed cancer in 92/180 (51%) patients. Malignancy was present in 40/108 (37%) FN, 12/29 (41%)
HN, and 40/43 (93%) SPTC. Nodule borders (irregular), shape (height > width), hypoechogenicity, and presence of microcalcifications
were significantly associated with malignancy. The presence of 2 or ≥3 adverse SUS thyroid nodule features was associated
with a ≥55% or ≥78% risk of malignancy, respectively.
Conclusion Adverse thyroid nodule features seen on SUS may predict malignancy and help determine the initial extent of thyroidectomy
in patients with indeterminate FNA cytology.

Background
Fine-needle aspiration cannot reliably determine malignancy in patients with Hürthle cell neoplasms (HCNs) of the thyroid. Thyroid nodule size and characteristics determined by surgeon-performed ultrasound (SUS) may be useful for predicting malignancy in HCN preoperatively. This study examined whether tumor size and features by SUS can reliably predict malignancy in patients with HCN.Materials and methods
We performed a retrospective review of 84 patients with HCN by fine-needle aspiration, who underwent SUS and thyroidectomy from 2002 to 2010. All patients underwent thyroid lobectomy with isthmusectomy unless there was a history of radiation exposure, familial thyroid cancer, obstructive symptoms, bilateral nodules, and/or patient preference, in which case total thyroidectomy was performed. Tumor size and malignant features by SUS were correlated with final histopathology using multivariate regression analysis.Results
On final histopathology, 29 patients had malignant thyroid nodules and 55 patients had benign ones. There were no statistically significant differences in terms of age, race, ethnicity, or gender between HCN patients who revealed malignant or benign nodules on final pathology. Tumor size ≥ 4 cm measured by SUS did not predict malignancy in HCN. Hypoechogenicity and hyperechogenicity were significantly associated with malignancy, whereas isoechogenicity was predictive of benignity (P = 0.044). No other ultrasonographic features were predictive for thyroid carcinoma by multivariate analysis.Conclusions
Tumor size and features determined by SUS do not reliably predict malignancy in patients with HCN. Such patients at risk for malignancy should initially undergo thyroid lobectomy for definitive diagnosis. 相似文献5.
BACKGROUND: The optimal management of cytologically indeterminate thyroid nodules is controversial given the variable malignancy rates reported in this patient population. We examined the prevalence of malignancy within cytologically indeterminate follicular thyroid lesions in an attempt to predict malignancy based on cytologic features. METHODS: Cytopathology reports obtained after fine-needle aspiration biopsy (FNAB) examination of indeterminate follicular thyroid lesions were examined over a 4-year period. The prevalence of malignancy on final histology was determined in 4 indeterminate cytologic categories. RESULTS: A total of 107 records were available (91 women, 16 men). The mean patient age was 45.4 +/- 16 years. Forty-eight patients (45%) underwent surgery and had histopathologic diagnosis, while 57 patients did not have surgery. The prevalence of malignancy in patients who underwent thyroidectomy was 42% (20 of 48). CONCLUSIONS: The high prevalence of malignancy within indeterminate follicular lesions may necessitate thyroidectomy for patients with indeterminate follicular lesions on FNAB examination. 相似文献

A comparison of total thyroidectomy and lobectomy in the treatment of dominant thyroid nodules 总被引:2,自引:0,他引:2
Patients with a clinically concerning dominant thyroid nodule have been managed by lobectomy or total thyroidectomy at our institution. We determined the complications associated with both approaches and the ability of thyroid lobectomy to avoid the need for thyroid hormone replacement therapy. Records of all patients with a dominant thyroid nodule managed with surgery from August 1993 through December 2000 were reviewed for demographics, history of head and neck radiation, indication for surgery, preoperative fine-needle aspirate results, final pathologic evaluation, perioperative complications, determinations of need for subsequent thyroid surgery after lobectomy, and need for thyroid hormone replacement therapy after surgery. Patients with a preoperative diagnosis of malignancy or bilateral or diffuse disease were excluded because these conditions would uniformly be managed by bilateral thyroidectomy. The complications for the lobectomy group (n = 131) compared with the total thyroidectomy group (n = 84) were: recurrent laryngeal nerve paresis (4.6% vs 2.4%), recurrent laryngeal nerve injury (0.8% vs 0), and transient hypoparathyroidism (1.5% vs 9.5%; P = 0.007). No permanent hypoparathyroidism was identified in either group. Postoperative thyroid hormone replacement was required in 64 of 131 lobectomy patients (48.8%). Complications associated with either surgery were low. Total thyroidectomy was not associated with clinically significant additive morbidity. Patients treated by lobectomy should be aware of a nearly 50 per cent chance of requiring thyroid hormone replacement. Total thyroidectomy avoids future thyroid surgery; lobectomy patients remain at risk. When complications can be minimized total thyroidectomy should be considered an option in the management for patients with dominant thyroid nodules that require surgery. 相似文献

Thyroid nodules in children are extremely uncommon. Most thyroid nodules, both benign and malignant, present as asymptomatic neck masses. A thyroid nodule in a child is significant because of the risk of malignancy. A review of medical records at our institution demonstrated 71 patients 20 years of age and younger with surgically managed thyroid nodules, of which 45 were benign and 26 were malignant. Our diagnostic workup, including serum thyroid studies, radiologic evaluation, and fine-needle aspiration, is discussed. Because of the possibility of malignancy, we recommend that all solitary thyroid nodules be excised in children unless fine-needle aspiration definitively determines a benign histology. The extent and type of surgical management is controversial and is still subject to much debate. Partial thyroidectomy appears adequate for benign disease, but even though there is no statistical difference in survival, we recommend total thyroidectomy for the management of malignant disease.

IntroductionWe report the case of an incidental solitary renal cancer cell (RCC) thyroid metastatic nodule treated by thyroidectomy.Presentation of caseA 53 year male presented with a solitary, asymptomatic thyroid nodule. He was treated with left nephrectomy 1 year before for a RCC. Radiological standard follow-up was negative for secondary lesions but ultrasound (US) 12 months after surgery revealed a 1.5 cm solid nodule in the right lobe of the gland. Fine needle aspiration biopsy (FNAB) was inadequate and the patient was submitted to total thyroidectomy. Histology showed the presence of solitary metastasis from RCC. At 2 years follow-up, no evidence of recurrence has been found.DiscussionSolitary RCC metastasis to the thyroid usually occurs late from nephrectomy and have no specific US pattern. When FNAB provides an uncertain cytological results, the patient received thyroidectomy for primary thyroid tumors and diagnosis of metastases from RCC was incidentally made.ConclusionThyroid nodules in a patient with history of malignancy can pose a diagnostic challenge. The presence of a solitary thyroid nodule in a patient with history of RCC should be carefully suspected for metastasis. We suggest to extend at neck the thorax and abdomen CT scan routinely recommended during the follow-up in high-risk cases. Thyroidectomy may result in prolonged survival in selected cases of isolated thyroid metastasis from RCC. 相似文献

BackgroundCurrent data regarding the risk of malignancy in a large thyroid nodule with benign fine-needle aspiration biopsy(FNAB) is conflicting. We investigated the impact of patient age on the risk of malignancy in nodules≥4 cm with benign cytology.MethodsWe performed a single-institution retrospective review of patients who underwent surgery from 07/2008–08/2019 for a cytologically benign thyroid nodule ≥4 cm. The relationship between malignant histopathology and patient and ultrasound features was assessed with multivariable logistic regression.ResultsOf 474 nodules identified, 25(5.3%) were malignant on final pathology. In patients <55 years old, 21/273(7.7%) nodules were malignant, compared to 4/201(2.0%) in patients ≥55. Patient age ≥55 was independently associated with significantly lower risk of malignancy(OR:0.2,95%CI:0.1–0.7,p = 0.011). Increasing nodule size >4 cm and high-risk ultrasound features were not associated with risk of malignancy(OR:1.0,95%CI:0.7–1.4,p = 0.980, and OR:9.6,95%CI:0.9–107.8,p = 0.066, respectively).ConclusionsPatients <55 years old are 3.7-fold more likely to have a falsely benign FNA biopsy in a nodule≥4 cm. 相似文献

OBJECTIVE: To evaluate the long-term outcome of patients treated by lobectomy for solitary thyroid nodule. DESIGN: Retrospective study. SETTING: University hospital. PATIENTS: 83 patients admitted with a clinical diagnosis of solitary thyroid nodule. INTERVENTIONS: Preoperative ultrasonography showed a solitary nodule in 32 patients and this finding was confirmed intraoperatively in 24 cases (77%). 59 patients with multinodular goitres were treated by total thyroidectomy and 24 with solitary nodule by lobectomy. MAIN OUTCOME MEASURES: Postoperative complications and freedom from nodule recurrence and/or parenchymal irregularity. RESULTS: One patient after lobectomy and 3 after total thyroidectomy developed temporary recurrent laryngeal nerve injury. Postoperative temporary hypoparathyroidism occurred in 13 patients (22%) after total thyroidectomy and in no patient after lobectomy (p = 0.02). Neither permanent recurrent laryngeal nerve injury nor permanent hypoparathyroidism occurred after either procedure. Among patients who underwent lobectomy, 6 had an adenoma and 18 had a nodular hyperplasia. At 4-year follow-up, the freedom rate from any thyroid nodule recurrence or parenchymal irregularity was 44.7%, and the freedom rate from nodular recurrence was 74%. Men tended to have a 4-year freedom rate from nodular relapse poorer than women (48% vs. 87%. p = 0.07). Nodular recurrence occurred in one patient operated on for an adenoma, and all the other recurrences occurred in patients with nodular hyperplasia. CONCLUSIONS: The mid-term freedom rate from thyroid nodule recurrence or parenchymal irregularity after lobectomy for solitary nodule of the thyroid is unsatisfactory. This observation calls for a better evaluation of long-term results after lobectomy for this condition and identification of risk factors predictive of recurrence. This would enable a more appropriate preoperative selection of patients undergoing lobectomy, indicating total thyroidectomy for those patients with solitary nodule at high risk of recurrence. 相似文献

OBJECTIVE: To identify the indications and outcomes of total thyroidectomy for Graves' disease in a North American cohort. STUDY DESIGN AND SETTING: Prospective database of 297 patients undergoing total thyroidectomy in a tertiary care center identified 49 patients with Graves'. RESULTS: There were 37 women and 12 men (mean age, 37.9 years). Common indications for surgery were: refusal of radioactive iodine (20%), thyroid storm (18%), a thyroid nodule (16%), failure of I131(14%), and ophthalmopathy (14%). Complications included: symptomatic hypocalcemia (14%), permanent hypoparathyroidism (0%), and symptoms of recurrent laryngeal nerve injury (0%). Graves' patients had more bleeding (117 mL versus 48 mL, P<0.05). Clinical nodules were malignant in 38%. Papillary thyroid carcinoma occurred in 10% of patients, with 60% multifocal, and 60% lymph node metastases. CONCLUSION: Total thyroidectomy for Graves' has minimal morbidity. Patients with Graves' and a thyroid nodule are at an increased risk for malignancy and should be treated with a total thyroidectomy. 相似文献

The relationship between Graves' disease or its therapy and carcinoma of the thyroid remains uncertain. We studied 20 patients found to have thyroid cancer in glands previously treated for Graves' disease between 1961 and 1986 at the University of Chicago Medical Center. Sixteen (80%) occurred in women and four (20%) occurred in men. The mean age at operation was 37 years (range, 19 to 69 years) and did not differ by sex. Fifteen of the 20 cancers (75%) were papillary while five (25%) were follicular. Six individuals (30%) had a history of external radiation to the head and neck as an infant, child, or young adult. Two others had received radioiodine (RAI) therapy for Graves' disease 1 and 19 years earlier. Patients were divided into three groups: group I: four patients (20%) had a neck mass 4, 14, 20, and 41 years after having had a subtotal thyroidectomy (STT) for Graves' disease; three of four had a history of external irradiation therapy. These tumors behaved aggressively, resulting in the death of two of the four patients. group II: 11 patients (55%) had diffusely enlarge toxic goiters without a nodule. A carcinoma was diagnosed intraoperatively on frozen section in only two of these patients. The others received STT. After recognition on permanent section, those carcinomas that were 4 mm or greater in diameter received postoperative RAI. One recurrence occurred and was treated successfully with further RAI. group III: Five patients (25%) had Graves' disease and a palpable thyroid nodule. None of them had had a prior thyroidectomy for Graves' disease, as in group 1. Thyroid carcinoma was diagnosed in all patients preoperatively or intraoperatively, and a total thyroidectomy was performed. Each patient is alive and well with a mean follow-up of 5 years. Between 1971 and 1981, 194 patients had surgery for Graves' disease, and 10 (5.2%) were found to have an associated carcinoma; six patients (3.1% of the total) did not have a nodule or any other suspicion of malignancy before surgery. During the same time, 303 patients received RAI therapy for Graves' disease and one (0.3%) has subsequently developed thyroid carcinoma. Thyroid cancer associated with Graves' disease is found more commonly in surgically treated patients than in patients after RAI therapy. The greatest risk factor in our patients was previous external radiation to the head and neck. Such individuals should be treated with total thyroid ablation rather than the usual STT, since they are at risk of developing aggressive thyroid cancers if thyroid remnants are left. 相似文献

Thyroid tuberculosis is a very rare condition even if the incidence of extrapulmonary forms of tuberculosis has increased. We report the case of a 56-year old female patient with tuberculosis of the thyroid gland and tubercular lymphadenitis of the neck mimicking thyroid malignancy. The diagnosis was established on histological examination after surgery in August 2002. Total thyroidectomy and central neck dissection were performed for very hard euthyroid multinodular goiter and paratracheal bilateral lymphadenopathy. There were no evidence of tubercular involvement of the other organs. The patient underwent combination treatment with antitubercular drugs for 6 months. During the three years follow-up period there was no evidence of disease recurrence. 相似文献

HYPOTHESIS: To investigate the impact of total thyroidectomy on the rate of completion thyroidectomy for incidentally found thyroid cancer in euthyroid multinodular goiter. DESIGN: A randomized, prospective clinical trial. SETTING: A tertiary referral center. PATIENTS: Patients with euthyroid multinodular goiter without any preoperative suspicion of malignancy, history of familial thyroid cancer, or previous exposure to radiation were randomized (according to a random table) to total or near-total thyroidectomy leaving no remnant tissue or less than 1 g (group 1; n = 109) or bilateral subtotal thyroidectomy leaving 5 g or more of remnant tissue (group 2; n = 109). Patients with preoperative or perioperative suspicion of malignancy were excluded. MAIN OUTCOME MEASURES: We compared the complication rates and the incidence of thyroid cancer requiring radioactive iodine ablation and completion thyroidectomy between groups. RESULTS: There were no permanent complications. The rates of temporary unilateral vocal cord dysfunction and hypoparathyroidism showed no significant difference between groups 1 and 2 (0.9% vs 0.9% and 1.8% vs 0.9%, respectively; P>.05). Papillary cancer was found in 10 group 1 patients (9.2%) and 8 group 2 patients (7.3%) (P =.80). Of the 9 patients requiring radioactive iodine ablation, reoperation was avoided in 5 group 1 patients; the remaining 4 group 2 patients underwent completion thyroidectomy (P =.007). CONCLUSION: We recommend total or near-total thyroidectomy in multinodular goiter to eliminate the necessity for early completion thyroidectomy in case of a final diagnosis of thyroid cancer. 相似文献

The 2015 American Thyroid Association (ATA) and 2017 American College of Radiology: Thyroid Imaging, Reporting and Data System (ACR TI-RADS) guidelines are two popular guidelines adopted to stratify sonographic risk of malignancy for thyroid nodules, and to select cases for fine-needle aspiration (FNA). To understand the test performance of the two systems in predicting thyroid malignancy, 164 thyroidectomy cases performed in a regional hospital in Hong Kong between January 2021 and June 2022 were reviewed. Sonographic images of the index nodule in each case were retrospectively classified into different risk categories using the ATA and ACR TI-RADS guidelines, respectively, followed by retrieval of cytological and pathological results, for comparison. The index nodule was proven malignant in 26.8% of cases in the final pathology. There was a strong and positive correlation between the ATA and ACR TI-RADS risk categories assignment (rs = .931, p < .001). Recommending FNA according to the ATA had a better sensitivity for malignancy than using the ACR TI-RADS (81.8% vs 72.7%), at the expense of a lower specificity (10.8% vs 40.8%). The sensitivity for malignancy of both systems could be further improved if all fluorodeoxyglucose (FDG)-avid nodules were investigated with FNA regardless of sonographic features and size. There was a statistically significant association between “nodules with FDG avidity and nodules recommended for FNA by the ACR TI-RADS guideline” and an eventual malignant thyroid nodule (p = .002). 相似文献

Background
Whether a threshold nodule size should prompt diagnostic thyroidectomy remains controversial. We examined a consecutive series of patients who all had thyroidectomy for a ≥4 cm nodule to determine (1) the incidence of thyroid cancer (TC) and (2) if malignant nodules could accurately be diagnosed preoperatively by ultrasound (US), fine needle aspiration biopsy (FNAB) cytology and molecular testing.Methods
As a prospective management strategy, 361 patients with 382 nodules ≥4 cm by preoperative US had thyroidectomy from 1/07 to 3/12.Results
The incidence of a clinically significant TC within the ≥4 cm nodule was 22 % (83/382 nodules). The presence of suspicious US features did not discriminate malignant from benign nodules. Moreover, in 86 nodules ≥4 cm with no suspicious US features, the risk of TC within the nodule was 20 %. US-guided FNAB was performed for 290 nodules, and the risk of malignancy increased stepwise from 10.4 % for cytologically benign nodules, 29.6 % for cytologically indeterminate nodules and 100 % for malignant FNAB results. Molecular testing was positive in 9.3 % (10/107) of tested FNAB specimens, and all ten were histologic TC.Conclusions
In a large consecutive series in which all ≥4 cm nodules had histology and were systematically evaluated by preoperative US and US-guided FNAB, the incidence of TC within the nodule was 22 %. The false negative rate of benign cytology was 10.4 %, and the absence of suspicious US features did not reliably exclude malignancy. At minimum, thyroid lobectomy should be strongly considered for all nodules ≥4 cm. 相似文献18.
BackgroundHemi-agenesis of thyroid is a rare congenital condition with the clinical significance lying only in cases where the remnant tissue is affected by a pathology mandating removal of the gland. Henceforth, the hemi-thyroidectomy technically becomes a total thyroidectomy with a need for long term thyroid replacement therapy.Case summaryWe present a series of three cases noted over a period of two years where preoperative imaging evaluation confirmed the developmental abnormality. Further presence of a thyroid nodule in each of these cases posed a specific clinical situation whereby characterization of nodule appeared mandatory for a rational management involving life-long thyroid replacement therapy due to an ‘apparent total thyroidectomy’, if the remnant gland is removed. Ultrasound TI-RADS is a new system for evidence based sub-classification of thyroid nodules enabling both the surgeon and patient to take a streamlined decision about the overall approach for management.ConclusionProspective nodule characterization based on the thyroid image reporting and data system (TI-RADS), enables the surgeon to decide the treatment strategy sparing the patient of the cost and morbidity associated with long term thyroid replacement therapy. 相似文献

The aim of the study was to analyze the frequency of incidental thyroid carcinoma (unknown tumor smaller than or equal to 10 mm) in a consecutive series of 462 total thyroidectomies for multinodular goiter and to investigate the clinical risk factors for this type of malignancy. A retrospective, single-center study of outcome data collected from patients with preoperative diagnosis of multinodular goiter who underwent total thyroidectomy at the General Surgery Unit of Pavia (Italy) between January 2000 and December 2008 was performed. Possible risk factors for malignancy were: gender, age, time of evolution of goiter, presence of a dominant nodule in multinodular goiter, hyperthyroidism, history of radiation to the neck, residence in an area of endemic goiter, prior thyroid surgery, calcifications in the goiter detected by neck ultrasound or chest X-rays, and a family history of thyroid diseases. In a 9-year period, 462 patients underwent total thyroidectomy. We found 41 cases of incidental thyroid carcinoma; the most common histopathological type was papillary. The multivariable analysis demonstrated that the clinical variables associated with occult carcinoma were a personal history of radiation therapy to the neck, the presence of calcifications detected by ultrasound or neck X-rays, and a family history of thyroid diseases; residence in an area of endemic goiter was a protective factor. A personal history of radiation to the neck, detection of calcifications by ultrasound or by neck X-rays, and a family history of thyroid diseases should be considered clinical risk factors for malignancy in multinodular goiter. 相似文献

Total Thyroidectomy for Benign Thyroid Disorders in an Endemic Region 总被引:23,自引:2,他引:21
Total thyroidectomy is increasingly being accepted as a treatment of choice for differentiated thyroid cancer. However, because
of presumed increased morbidity associated with this procedure, it is still not considered a viable option for management
of benign thyroid disorders. To assess the safety and efficacy of total thyroidectomy for management of benign thyroid disorders,
we analyzed our data from 127 total thyroidectomies performed for benign thyroid disorders. Demographic details, biochemical
findings, indications for operation, specimen weight, and complications were noted. Among these patients, 52 had a toxic goiter
and 75 had a nontoxic goiter. The mean duration of the goiters being present was 6.08 ± 6.06 years (0.9–26.0 years), and the
mean weight of the specimens was 136.88 ± 120.68 g. The incidence of occult malignancy was 6.3% (n= 8), and those of permanent hypothyroidism and permanent recurrent laryngeal nerve palsy were 1.6% and 0.8%, respectively.
Total thyroidectomy should be considered a treatment of choice for multinodular goiter and Graves' disease in a setting of
palpable nodule(s) or ophthalmopathy (or both). It is particularly relevant in endemic regions where patients present with
a long-standing, large nodular goiter with virtually no normal thyroid tissue. Reoperation for recurrent goiter in such a
setting would be fraught with distressing complications. 相似文献
