Recurrence of goitre after operation in euthyroid patients

OBJECTIVE: To try and resolve some of the problems associated with the treatment of goitre in euthyroid patients. DESIGN: Retrospective open study SETTING: University hospital SUBJECTS: 106 out of a total of 161 euthyroid patients operated on for goitre from 1974-1988. Those who underwent total thyroidectomy (n = 14), in whom the histological diagnosis was thyroiditis (n = 10), or who were lost to follow up (n = 31) were excluded from the study. MAIN OUTCOME MEASURES: Recurrence of goitre, and correlation with type of operation, age, and histological type. RESULTS: 62 Patients underwent unilateral, and 44 bilateral resections. There were 24 recurrences (23%), 13 of which were subclinical; 19 occurred after unilateral, and 5 after bilateral, resections (p = 0.02). There were no significant associations between recurrence and age or histological type. CONCLUSION: Subtotal thyroidectomy is the treatment of choice for goitre in euthyroid patients.     

Papillary microcarcinoma of the thyroid. 179 cases reported since 1973

OBJECTIVES: Defined as a tumor measuring < or = 1 cm, the prognosis and treatment of occult papillary thyroid carcinoma has been the topic of some controversy. The aim of this study was to report experience with a series of 179 cases observed since 1973. PATIENTS AND METHODS: Occult papillary thyroid carcinoma was discovered in 179 patients aged 12 to 81 years (151 women and 28 men) at cervicotomy prescribed for Graves' disease (n = 9), toxic adenoma (n = 16), isolated nodule (n = 71), multinodular goiter (n = 74) or cervical node enlargement (n = 9). The surgical procedures were lobo-isthmectomy (n = 79), subtotal thyroidectomy (n = 74), or total thyroidectomy (n = 26) with node dissection in case of enlargement. Thyroxin was prescribed in all cases and annual follow-up was programmed. Five patients were lost to follow-up. RESULTS: Two cervical recurrences were observed warranting reoperation. None of the patients died from cancer-related causes. CONCLUSION: Minute papillary carcinomas of the thyroid are frequently discovered, but prognosis is generally excellent. Systematic total thyroidectomy and node dissection are not warranted. Only those lesions with an extrathyroid extension, associated node enlargement or inaugural metastasis require wide resection. These results are in agreement with a critical analysis of data reported in the literature demonstrating the exceptional nature, and in half of the cases, cure of metastatic occult papillary thyroid carcinoma.     

The risk of infective thyroiditis in nodular goitres

Infective thyroiditis which was more common in the pre-antibiotic era is now rare in developed countries but continues to occur in less developed areas. Over a 10-year period in Zaria, Nigeria which is situated in an endemic goitre region, nine such patients were treated. All were females, 30-50 years of age and had pre-existing, long-standing multinodular goitres. During the period, 84 patients (including the nine patients) with endemic multinodular goitres were treated, giving an infective rate of 10.7% in these goitres. Treatment was by adequate incision and drainage in all patients with suppuration. Staphylococcus aureus was the commonest organism cultured and Streptococcus Pyogenes and Pseudomonas were the infective agents in a minority. Only one patient required thyroidectomy later, the goitre having disappeared in the other patients. One patient developed hypothyroidism requiring replacement therapy with thyroxine. Thyroid abscess remains an ever present risk in endemic multinodular goitres in our environment. Early presentation after onset of pain, prompt administration of appropriate antibiotics and thyroidectomy soon after is likely to reduce the risk of abscess formation in these goitres.     

Technetium-99m tetrofosmin imaging in thyroid diseases: comparison with Tc-99m-pertechnetate, thallium-201 and Tc-99m-methoxyisobutylisonitrile scans

Technetium-99m tetrofosmin is a lipophilic phosphine used for myocardial perfusion imaging. Biodistribution studies have shown significant thyroid uptake of tetrofosmin and preliminary reports have suggested that tetrofosmin imaging may be of value in patients with thyroid cancer. In this study, tetrofosmin whole-body scintigraphy was performed in 35 patients with evidence of thyroid diseases. All patients underwent laboratory evaluation of thyroid function as well as 99mTc pertechnetate scan, thallium-201 (n=16) 99mTc-methoxyisobutylisonitrile (MIBI) (n=19) whole-body studies. Thyroid images were semi-quantitatively analysed by a 4-point score: 0=no significant uptake; 1=uptake increased as compared to background activity, but inferior to normal thyroid tissue; 2=uptake equal to normal thyroid tissue; 3=uptake superior to normal thyroid tissue. Pathology examinations were obtained. A total of 41 thyroid nodules were detected, of which 15 were goitre nodules, 13 adenomas and 13 malignant lesions. In goitre nodules, concordant results of tetrofosmin and pertechnetate uptake (score 1 or 0) were observed in the majority of lesions (87%). In function adenomas (n=10), both tetrofosmin uptake and pertechnetate uptake were score 3. In non-function adenomas (n=3), tetrofosmin uptake was score 3, while pertechnetate uptake was score 0. In six malignant lesions, tetrofosmin uptake was score 3, while pertechnetate uptake was score 0; in the other seven lesions, where a prevalence of goitre abnormalities was observed, results of tetrofosmin and pertechnetate uptake were similar (score 0 or 1). In seven (70%) of the ten patients with malignant nodules, whole-body tetrofosmin images showed increased abnormal uptake in a total of 28 extra-thyroid tumour sites, as subsequently confirmed by other techniques. When tetrofosmin images were compared to 201Tl and 99mTc-MIBI scans, concordant results were observed in all cases. In conclusion, tetrofosmin imaging may be particularly useful to characterize and stage patients with malignant thyroid nodules; it shows similar results to thallium but provides better image quality. Comparable findings were observed between tetrofosmin and MIBI studies. Thus, tetrofosmin may be an alternative to thallium and MIBI in the aforementioned patients.     

Clinically significant, isolated metastatic disease to the thyroid gland

Despite being second only to the adrenal glands in terms of relative vascular perfusion, the thyroid gland is a rare site of metastatic disease; but when thyroid metastases occur, long-term survival has been reported to be dismal. To determine the incidence and management of isolated, metastatic disease to the thyroid, we reviewed our clinical experience. Between June 1986 and August 1994 ten patients underwent thyroidectomy for isolated, metastatic disease of nonthyroidal origin (mean +/- SD age 58 +/- 6 years, 30% female). The primary tumors were renal cell carcinomas (RCCs) (n = 5), esophageal adenocarcinoma (n = 1), pulmonary squamous cell carcinoma (n = 1), gastric leiomyosarcoma (n = 1), lingual squamous cell carcinoma (n = 1), and parotid gland carcinoma (n = 1). Three patients underwent preoperative fine-needle aspiration (FNA), all of which were suggestive of metastatic disease. The mean time from resection of the primary tumor to thyroid metastases was 3.5 +/- 6.0 years (range 0-19.5 years). Total thyroidectomy (n = 5) or lobectomy (n = 5) was performed without morbidity or mortality. After a median follow-up of 5.2 years six patients are alive and two are free of disease. Moreover, no patients have had recurrent disease in the neck. Thus carcinomas metastatic to the thyroid represent a rare cause of clinically significant thyroid disease, with RCCs comprising 50%. Most thyroid metastases (80%) present within 3 years of primary tumor resection, but with RCC they can occur as late as 19 years. The diagnosis of metastatic disease should be suspected in patients with even a remote history of cancer, especially RCC, and an FNA revealing clear cell or spindle cell carcinoma. Contrary to previous reports, long-term survival can be achieved after resection of the metastatic tumor. Furthermore, thyroidectomy may also palliate/prevent the potential morbidity of tumor recurrence in the neck.     

Thyroidectomy without drainage

Recent randomized series did not support routine prophylactic drainage after thyroidectomy. We undertook a prospective study in order to evaluate the effectiveness and the morbidity of a non drainage strategy after thyroidectomy. Between april 1993 and may 1995, one hundred fifty consecutive patients underwent thyroidectomy without drainage. During this period, two thyroid cancers were treated by total thyroidectomy with a modified radical neck dissection and drainage; they are not included in the study. Age range was 16 to 72 years. Sex ratio was 126F/124M. Indication for surgery was: solitary nodule (16), multinodular goiter (56), Graves' disease (21), toxic nodular goiter (34), cancer (8), retrosternal goiter (13), thyroiditis (2). The surgery done was: total lobectomy + isthmusectomy (15), total lobectomy + subtotal controlateral thyroidectomy (42), bilateral subtotal thyroidectomy (84), total thyroidectomy (9). Surgical technique was identical to that used previously by the author when drainage was installed routinely. Patients left the hospital on the first or second postoperative day and were reexamined on day 7 and day 30. There was no mortality, no suffocating hematoma, no reoperation and no laryngeal nerve paralysis. One patient developed a transient hypocalcemia that regressed one month later. Two patients developed a minor hematoma of which one disappeared after two weeks and the other drained spontaneously through the surgical incision on the seventh postoperative day. We conclude that drainage after thyroidectomy has no adverse effects and can be avoided if meticulous surgery is done. Absence of drainage simplifies the early postoperative course, improves the comfort of the patient, decreases hospital stay and reduces hospital cost. However, drainage may be of value in case of hemostatic problems or associated cervical neck dissection.     

Thyroid gland surgery at the 1st Surgical Clinic of the 1st Medical School of Charles University and General Medical School Hospital in Prague--review of problems

The authors analyze a group of 100 patients indicated for goitrectomy during the period from 1995-1996. The most frequent indication for surgery was an eufunctional polynodular goitre. The group comprised 86 women and 14 men. Their mean age was 47 years, bilateral affections predominated. The most frequent type of operation was total thyroidectomy. Carcinoma was found in three of the operated patients. The mean period of hospitalisation was 6 days. Postoperative complications were more frequent after total goitrectomies, and with the extent of the operation the number of possible complications increased. The most serious complication in the authors opinion was a lesion of the parathyroid glands, observed in 5% of the patients. Permanent unilateral lesions of the recurrent nerve were recorded in 2% of the operated patients. There was no lethal postoperative complication. The largest operated goitre weighed 625 g (photograph 1). The authors conclude that it cannot be stated that the operation of larger goitres is associated with the highest incidence of postoperative complications. The opposite is rather the case.     

Surgical management of toxic goitre in Khartoum

Seventy patients with toxic goitre treated surgically in two surgical firms in Khartoum during a 10-years period were studied. Of these patients 62.9% had diffuse goitres, 34.3% nodular and 2.8% hot clinically solitary nodules. The age ranged between 15 and 54 years and the M:F ratio was 1.0:6.7. Ninety per cent of the patients had large size goitres (grade III). Preoperative carbimazole and inderal were found to be superior to other drug combinations. Subtotal thyroidectomy was the standard procedure and no serious postoperative complications were noted. Fifteen patients had postoperative hectic period i.e. fever, headache and tachycardia that responded to temporary inderal and steroids. Surgical treatment of toxic goitre in developing countries could be extended to include more patients since drug availability and patient compliance are minimal.     

Long-term effect of 131I therapy of multinodular non-toxic goiter

The aim of this study was to investigate the long term effect of 131I treatment on thyroid function and size in patients with non-toxic multinodular goitre. The subjects were 69 consecutive patients with multinodular non-toxic goitre selected for 131I treatment and followed for a minimum of 12 months. Outcome measures were standard thyroid function variables and ultrasonically determined thyroid volume before and after treatment. Fifty-nine patients were treated with a single dose of 131I, 12 with two doses, and one with four doses. In 45 patients treated with one dose who remained euthyroid the median thyroid volume was reduced from 73 (interquartile range 50-106) ml to 29 (interquartile range 23-48) ml at 24 months. The median reduction was 40 (22-48) ml, half of which occurred within three months. Patients treated with two doses as well as those developing hypo- or hyper-thyroidism also had a significant reduction in thyroid volume. Eleven patients developed hypothyroidism (cumulative five year risk 22%). Side effects were few. In conclusion we find that 131I treatment of multinodular non-toxic goitre is an attractive alternative to surgery.     

Long-term follow-up of immunosuppressive treatment for obstructive airways disease after allogeneic bone marrow transplantation

BACKGROUND: Locally advanced thyroid cancer invading the tracheal cartilage represents a difficult treatment dilemma during thyroidectomy. METHODS: A retrospective chart review was performed to determine the results of laryngotracheal resection or tracheal cartilage shave with adjuvant radiotherapy in patients with locally advanced thyroid cancer invading the upper airway. RESULTS: Of 597 patients undergoing thyroidectomy for thyroid cancer, 40 were found to have laryngotracheal invasion. Thirty-five patients with superficial invasion underwent cartilage shave procedures with adjuvant radiotherapy; five with full-thickness invasion underwent radical resection, including tracheal sleeve resection (n = 3) or total laryngectomy (n = 2). Histologic subtypes included papillary (n = 32), follicular (n = 2), Hurthle cell (n = 1), medullary (n = 3), and anaplastic (n = 2). Of the cartilage shave group, 25 are currently alive with no evidence of disease at a mean follow-up of 81 months (range 1-290). Six developed isolated local/regional recurrence and were managed with total laryngectomy (n = 1), tracheal resection (n = 1), cervical lymphadenectomy (n = 1), or repeat radiotherapy (n = 3). All six patients remain free of disease at a mean follow-up of 5 years. Of those who underwent initial laryngotracheal resection, four remain free of disease at a mean follow-up of 5 years. The rates of 10-year disease-free survival and overall survival for all patients were 47.9% (95% confidence interval [CI] 24.8, 71.0) and 83.9% (95% CI 70.3, 97.5), respectively. CONCLUSIONS: These data suggest that adequate management of thyroid cancer with laryngotracheal invasion can be achieved with a more conservative surgical approach and adjuvant radiotherapy, reserving more radical resections for extensive primary lesions or locally recurrent disease.     

Basal metabolism of weight-stable chronically undernourished men and women: lack of metabolic adaptation and ethnic differences

The purpose of this study was to investigate whether weight-stable chronically energy-deficient subjects exhibit evidence of metabolic adaptation and to establish whether international predictive equations overestimate the basal metabolic rate (BMR) of tropical populations. BMR, body weight, height, and fat-free mass (FFM) by underwater weighing were measured in healthy, physically active urban dwellers of low socioeconomic status (178 men and women aged 22-38 y) in Bangalore, Southern India. Subjects were selected on the basis of body mass index (BMI; in kg/m2) and classified in three groups: severely undernourished (BMI < 17.0; n = 30 men, n = 25 women), marginally undernourished (BMI = 17.0-18.5; n = 31 men, n = 30 women), and well nourished (BMI > 18.5; n = 27 men, n = 35 women). The BMR of the well-nourished group, expressed in absolute terms (6.20 and 5.18 MJ/d for men and women, respectively), was significantly higher (P < 0.000) than that of the severely undernourished group (5.72 and 4.64 MJ/d for men and women, respectively). Normalizing BMR for either body weight or FFM by analysis of covariance abolished all differences. The mean BMR of the low-BMI study group was substantially higher (11-14%) than reported previously for undernourished Indian adults. The BMR of both men and women, regardless of their nutritional status, was accurately estimated by age- and sex-specific FAO/WHO/UNU equations. These findings suggest the absence of an enhanced metabolic response in weight-stable chronically undernourished adults. This is in contrast with earlier reports, and supports more recent views. The study also provides evidence of the absence of ethnic-specific energy turnover in Indians.     

Expression of type II cGMP-dependent protein kinase in rat kidney is regulated by dehydration and correlated with renin gene expression

To define the current indications for surgical management of pleuropulmonary tuberculosis and analyze the results of operative procedures, the records of 59 patients operated on between January 1987 and December 1993 were reviewed. Three patient categories were defined. Group I patients (n = 25) underwent operation for diagnostic purposes: solitary mediastinal node or mediastinal adenopathy associated with pulmonary lesions (n = 10), pulmonary infiltrates (n = 4), pulmonary nodules or masses (n = 10), or chronic pleurisy (n = 1). Postoperative mortality and morbidity rates in this group were both 4%. Group II patients (n = 18) underwent operation for active lesions: intrapulmonary cavity (n = 6), destroyed lung parenchyma (n = 6), or chronic loculated pleural effusion (n = 6). Postoperative morbidity and mortality rates were 16.6% and 5.5%, respectively. Group III patients (n = 16) underwent operation for a complication of therapy or for sequelae of previously "cured" tuberculosis: calcified pyothorax (n = 8), empyema (n = 2), fistulized nodes (n = 2), bronchiectasis (n = 3), or aspergilloma (n = 1). Morbidity and mortality rates in this group were 31.25% and 12.5%, respectively. Surgery continues to have both diagnostic and therapeutic indications for management of pleuropulmonary tuberculosis, despite the morbidity and mortality rates associated with operative procedures.     

Long-term results of two schedules of treatment for toxic multinodular goitre with radioiodine therapy

Results of the long-term effects of two schedules of radioiodine therapy I131 in 130 toxic multinodular goitre patients were evaluated. Seventy five patients (group I) were treated with low doses and 55 patients (group II) with calculated high doses adjusted for thyroid weight (0.5-1 mci/g) and radioiodine uptake. Follow up (mean +/- SEM) was 4.5 +/- 0.4 years and 4.8 +/- 0.6 years respectively (P > 0.1). At the end of follow up, hyperthyroidism was successfully reversed in 78% (Group I) and 82% (Group II). In group I hypothyroidism was present in 5% of patients, while it was 12.5% in group II patients. The total dose per gram of thyroid tissue was not significantly different in both the groups (.058 mci +/- .0054 VS .073 +/- .0054 mci/g). However in group II the number of I131 administration was significantly lower (1.5 +/- 0.2) than in group I (3.2 +/- 0.4). The percentage of patients who were adequately treated in Group II with single dose was more as compared in group I (62% in group II versus 40% in group I). Euthyroidism was reached in a shorter time after treatment in group II (median time 0.8 year in group II Vs 1.1 yrs in group I) It is concluded that radioiodine is an effective treatment for toxic multinodular goitre with a significant low incidence of post therapy hypothyroidism in patients treated with low doses as compared to higher doses of radioiodine therapy.     

Determination of skeletal age using the Oxford Score in children with epiphyseolysis of the femur head

Differentiated thyroid carcinoma often has a favourable prognosis. However, there is no unanimity about the surgical procedure used. In this analysis we evaluated the surgical complications of 178 patients operated on for differentiated thyroid carcinoma during a 12-year period. 110 of the patients were operated in one session and 68 in two. Total thyroidectomy was performed in 106 patients and ipsilateral lobectomy together with contralateral subtotal resection in 72 patients. Tumour was bilateral or multicentric in 59 patients (33%). Hypoparathyroidism occurred in eight patients (4%), without differences between total thyroidectomies and lobectomy plus subtotal resections. Hypoparathyroidism tended to be more common after completion resection than after completion thyroidectomy (4/28 vs 1/40; P = 0.08). Accidental injury to the recurrent laryngeal nerve occurred in one patient (0.6%) during a contralateral resection. During a median follow-up of 4.5 years, tumour recurrence was detected in 22 patients (12%). In papillary carcinoma it was more common in patients who had underwent lobectomy plus contralateral resection than after total thyroidectomy (11/60 vs 3/88; P < 0.01). However, the median follow-up times were unequal. In conclusion, total thyroidectomy and even completion thyroidectomy is as safe as less radical lobectomy together with contralateral resection. Thus, total thyroidectomy should be offered to all patients with differentiated thyroid carcinoma until there is a reliable method to recommend for those patients who can be treated with less radical procedures.     

Cervical reconstruction of the supra-aortic trunks: a 16-year experience

PURPOSE: The purpose of this study was to review 182 consecutive cervical reconstructions of supra-aortic trunks, which were performed over a 16-year period. METHODS: A total of 182 innominate, common carotid, or subclavian arteries were reconstructed with a cervical approach in 173 patients aged 23 days to 83 years. Indications included hemispheric (n = 79), vertebrobasilar (n = 56), upper extremity (24), and internal mammary/cardiac ischemia (n = 5), asymptomatic severe common carotid disease (n = 33), or other (n = 3). Primary atherosclerotic innominate (n = 6), common carotid (n = 84), and subclavian (n = 66) lesions underwent reconstruction. Thirty-one operations were performed for multiple trunk involvement, recurrent disease, arteritis, infection, dissection, coarctation, or aneurysm. There were 122 bypass grafting procedures (98 ipsilateral, 24 contralateral) and 60 arterial transpositions. RESULTS: One death (0.5%) and 7 nonfatal strokes (3.8%) occurred, none in patients who were asymptomatic. Perioperative morbidity included four asymptomatic occlusions (2%), 6 myocardial infarctions (3%), 10 pulmonary complications (5%), and 2 graft infections (1%). Follow-up periods ranged from 1 to 190 months (mean, 53 +/- 5 months). Nineteen patients (10%) were lost to follow-up. Fifty-seven late deaths occurred, most from cardiac causes. Seven reconstructions necessitated late revision. The cumulative primary patency rate at 5 and 10 years was 91% +/- 2% and 82% +/- 5%, respectively. The survival rate at 5 years was 72% +/- 4% and at 10 years was 41% +/- 6%. The stroke-free survival rate was 92% +/- 2% at 5 years and 84% +/- 2% at 10 years. CONCLUSION: Cervical reconstruction of symptomatic and asymptomatic supra-aortic trunk lesions carries acceptable death and stroke rates and provides a long-term patient benefit. This should be the preferred approach for asymptomatic lesions and for patients with significant comorbidity because it carries less morbidity than direct transmediastinal aortic-based reconstruction.     

Renal cell carcinoma: preoperative assessment for enucleative surgery with angiography, CT, and MRI

PURPOSE: Our purpose was to assess various imaging methods in detecting a pseudocapsule of renal cell carcinoma (RCC), which is critical for successful tumor enucleation. METHOD: In 42 patients with histopathologically proven RCC, images obtained at angiography (n = 42), CT (n = 30), and MRI (n = 19) were investigated retrospectively. All patients underwent treatment (enucleation: n = 15; nephrectomy: n = 27). The imaging criteria for the presence of a pseudocapsule were as follows: a surrounding radiolucent rim on angiography, a low or high density rim on CT, and a low intensity rim on MRI. All images were retrospectively reviewed by three radiologists without knowledge of the clinical and histological findings. RESULTS: Thirty-three of 42 RCCs showed a pseudocapsule on the surgical specimen. A pseudocapsule was detected in 67% of tumors (22/33) on angiography, 26% (6/23) on CT, 27% (4/15) on T1-weighted MRI, 93% (14/15) on T2-weighted MRI, 67% (8/12) on dynamic enhanced T1-weighted MRI, and 15% (2/13) on delayed enhanced T1-weighted MRI. CONCLUSION: T2-weighted MR images are superior for visualizing a pseudocapsule of RCC and for providing reliable selection criteria for tumor enucleation.     

Acetic acid iontophoresis and ultrasound for the treatment of calcifying tendinitis of the shoulder: a randomized control trial

OBJECTIVE: To assess the effects of acetic acid iontophoresis (AAI) and ultrasound on calcifying tendinitis of the shoulder, and to determine the relation between changes in the radiological measures of calcium deposit (CD) and shoulder function. DESIGN: Randomized control trial. SETTING: General community, private practice. PATIENTS: Twenty-two adults (7 men, 15 women) with a calcifying tendinitis of the shoulder, without associated conditions, stratified according to the type of lesions (X-ray: type I, fleecy appearance: type II, homogeneous), were randomly allocated to an experimental (EXP, n = 11) or to a control (CTL, n = 10) group. INTERVENTIONS: CTL group, no treatment; EXP group, nine treatments including AAI (5% acetic acid solution via the negative electrode, 5mA galvanic current, 20 minutes) followed by continuous ultrasound (0.8w/cm2, 1MHz, 5 minutes). MAIN OUTCOME MEASURES: Area and density of the CD, passive shoulder abduction (range of motion [ROM]), pain intensity. RESULTS: Significant reduction in the area and density of CD (ANCOVA, p = .01 and .03) over time in the EXP and CTL groups, but no significant difference between groups for any of the variables measured. The decrease in the area of CD in type I lesions (n = 5) was larger (Mann-Whitney U test, p < .01) than in type II (n = 16) lesions. The relation was stronger (rs = .90) between changes in area and density of CD than between ROM and pain (rs = -.67). Correlations were weak (rs = .21 to .41) between radiological and functional changes. CONCLUSION: The reduction in CD area and density likely results from a natural process rather than treatment (AAI and ultrasound); type I lesions (resorptive phase) are more likely to display resorption of the CD than type II lesions (formative phase). Reduction of the CD area does not necessary result in a functional improvement.     

Improved results in the management of surgical candidates with lung cancer

BACKGROUND: Perioperative mortality and morbidity after lung resection for carcinoma are generally reported to be 3% to 6% and 15% to 30%, respectively, and higher in the elderly and those with limited cardiopulmonary reserve. METHODS: To minimize this risk and extend the surgical option to more high-risk patients, we adopted a protocol in 1991 that included preoperative digitalis, subcutaneous heparin and venoocclusive stockings, aggressive perioperative pulmonary toilet, and video-directed limited resections for many patients with limited pulmonary reserve. In October 1996, we reviewed our results with 173 consecutive patients (median age, 60 years; range, 17 to 89 years) undergoing operation for suspected lung carcinoma. Forty-one patients were 70 years old or older, and 70 patients were considered high risk on the basis of advanced age (> or = 70 years), poor cardiac or pulmonary reserve, or serious medical comorbidity. Procedures included pneumonectomy (n = 31), lobectomy (n = 83), bilobectomy (n = 12), and limited resection (n = 45). Two patients had unresectable disease. RESULTS: Hospital mortality was 1.6% (3/173) and morbidity was experienced by 15% (26/173). Among the high-risk subgroup mortality was 4.2% (3/70) and morbidity was 20% (14/70; p < 0.03). For the older patients these values were 4.8% (2/41) and 17.9% (7/41), respectively. CONCLUSIONS: Morbidity and mortality from lung resections may be minimized with the perioperative management strategy outlined above. This would allow more high-risk patients to benefit from surgical resection, and do so with an acceptably low risk.     

Cystic thyroid lesions in children

BACKGROUND/PURPOSE: Cystic lesions of the thyroid encompass a wide and heterogeneous group of disease states in children, ranging from benign purely cystic entities to malignant tumors. The purpose of this study was to study both the presentation and management of cystic thyroid lesions in the pediatric population. METHODS: A retrospective review of all thyroid masses presenting between 1978 and 1996 and found to be purely or partially cystic on ultrasound examination was conducted, looking at presentation, family history, laboratory values, ultrasound scan and radionuclide imaging, and pathological and cytological evaluation. RESULTS: Twenty-four patients (19 girls, 5 boys) aged 6 to 18 years received the diagnosis of cystic lesions of the thyroid. Of these, 23 presented with painless neck masses, 21 were clinically euthyroid, only one had a single abnormal thyroid function test, only two had mildly positive antithyroid antibody test results, and nearly 30% had a positive family history of thyroid disease. Ultrasonography showed pure cysts in five patients and mixed solid cystic lesions in 19 patients. On scintiscan, six lesions were hot, 13 were cold, three showed normal uptake, and two were mixed. Treatment included either observation, aspiration, cyst sclerosis, surgery, or combinations thereof. Pathological and cytological results included follicular adenoma (n = 9), cystic degeneration (n = 6), multinodular goiter (n = 4), carcinoma (n = 2), branchial cleft cyst (n = 1), and undetermined (n = 2). CONCLUSIONS: Thyroid cysts are often thought to represent benign degenerative disease. Our study, which is the first in the literature to specifically address thyroid cysts in children, shows that ultrasound scan is useful in evaluating thyroid masses, whereas laboratory and radionuclide are of less value, and that single lesions of mixed echogeneity are likely to represent neoplasms, a significant percentage of which are malignant.     

Safety, efficacy, and cost of pancreaticoduodenal resection in a specialized center based at a community hospital

OBJECTIVE: To determine whether pancreaticoduodenal resection (PDR) for benign and malignant disease can be performed safely, efficiently, and economically at a 50-bed community hospital. DESIGN: Retrospective review of 39 consecutive PDRs performed in an 18-month period. Indications for surgery, length of hospital stay, complications, and patient charges were analyzed. SETTING: A suburban 50-bed community hospital. PATIENTS: Thirty-nine patients (15 male and 24 female) referred for PDR for benign and malignant disease. MAIN OUTCOME MEASURES: Mortality and morbidity rates, length of hospital stay, care, and cost. RESULTS: Of 39 patients who underwent PDRs, 1 patient (2.6%) died of myocardial infarct. Intraoperative blood transfusions were required by 3 patients (8%). The mean postoperative hospital stay was 11 days. Twenty-four patients (62%) were discharged by day 11. Fifteen patients (38%) were hospitalized 11 to 24 days. Complications in 10 patients (28%) included pancreatic or biliary fistula (n = 6), upper gastrointestinal tract bleeding (n = 1), partial wound dehiscence (n = 1), bacteremia (n = 1), and pneumonia (n = 1). No patient required reoperation. Three patients were rehospitalized within 1 month. Mean patient charges were $21,864, and mean reimbursements were $19,669. CONCLUSIONS: Pancreaticoduodenal resection can be accomplished with low morbidity and mortality rates and a short stay at a community hospital.
