ABSTRACT

ABSTRACT Objective: Our aim was to assess the ability of serum magnesium (Mg), measured on the first postoperative day (Mg1PO), to predict the need for calcium (Ca) replacement in patients undergoing total thyroidectomy (TT). Subjects and methods: Eighty patients undergoing TT, with Mg1PO and PTH dosage in the first (PTH1h) and eighth (PTH8h) hours after TT, were evaluated for the need for Ca replacement. Data were evaluated by uni/multivariate logistic regression and Receiver Operating Characteristic (ROC) curve. Results: 32 patients (40%) required Ca replacement. Median PTH1h, PTH8h and Mg1PO were higher in the no replacement group: 17 versus (vs) 3 pg/mL (p < 0.001), 18.2 vs 3.0 pg/mL (p < 0.001) and 2 vs 1.6 mg/dL (p < 0.001), respectively. Mg1PO was the isolated predictor for this replacement (odds ratio = 0.0004, 95% confidence interval: 0.000003-0.04; p = 0.001), with the cut-off value of 1.8 mg/dL showing sensitivity and specificity of 78.1% and 87.5%, respectively. Conclusions: In this group of patients, serum Mg1PO was the isolated predictor for the need for Ca replacement.

ABSTRACT

ABSTRACT Objective: Cytological analysis and Bethesda classification of thyroid nodules is the standard method of diagnosing differentiated thyroid carcinoma (DTC). However, even for nodules with a non-malignant cytological diagnosis, there is a not insignificant risk of cancer. There are doubts whether this lack of certainty would influence patient prognosis. Our aim was to compare patients with DTC, classified according to the preoperative cytological diagnosis, regarding their evolution. Subjects and methods: A retrospective study was carried out with 108 DTC patients submitted to total thyroidectomy (TT) between 2009 and 2015, divided into three groups according to preoperative cytological diagnosis (Bethesda classification): classes I/II, III/IV, and V/VI. Groups were compared for evolution considering response to treatment at last evaluation as well as time disease free. Statistical analysis used ANOVA, chi squared, and Kaplan-Meier curves with p<0.05 considered significant. Results: Groups differed for time between nodule puncture and TT [in months; V/VI (2.35 ± 2.48) < III/IV (7.32 ± 6.34) < I/II (13.36 ± 8.9); p < 0.0001]. There was no significant difference between groups for evolution at final evaluation (disease free status; classes I/II: 71.4%; classes III/IV: 60%; classes V/VI: 66.6%; p = 0.7433), as well as time disease free (in months; classes I/II: 34.57 ± 25.82; classes III/IV: 38.04 ± 26.66; classes V/VI: 30.84 ± 26.34; p = 0.3841). Conclusions: DTC patients classified according to preoperative cytological diagnosis did not differ for evolution. Although patients with non-malignant cytological diagnoses were submitted to TT later, this did not affect the evolution of the cases.

ABSTRACT

ABSTRACT Objective: Thyrotropin-stimulated thyroglobulin (STg) after total thyroidectomy is a prognosis marker for differentiated thyroid carcinoma (DTC). As Tg level is influenced by thyrotropin (TSH), perhaps the STg/TSH ratio is also a prognosis marker for these tumours. We aimed to compare STg/TSH ratio and first STg level in differentiated thyroid carcinoma patients for their ability to predict the long-term response to initial treatment. Subjects and methods: This retrospective study evaluated data from 181 DTC patients for first (1st) STg and STg/TSH ratio, at 1-3 months post-total thyroidectomy and before iodine-131 therapy, according to response to initial therapy [Excellent/Indeterminate or Incomplete (Biochemical/Structural)] observed at final evaluation, and with the survival time with excellent/indeterminate response. Results: Cases with incomplete response presented higher STg level [225.13 ± 585.26 ng/mL versus (vs) 20.4 ± 192.9 ng/mL; p < 0.001] and STg/TSH ratio (3.01 ± 7.8 vs 0.27 ± 2.58; p < 0.001). Cutoffs of 5 ng/mL for STg and 0.085 for STg/TSH displayed sensitivities of 76.7% and 76.9%, and specificities of 79.2% and 82.6%, respectively, in predicting response to therapy. Values below these cutoffs were associated with longer survival time in excellent/indeterminate response (140.4 vs 15.9 and 144.6 vs 15.9 months, respectively). Conclusion: STg/TSH ratio has a similar performance to the 1st STg in predicting long-term response to initial therapy.

ABSTRACT

Abstract Introduction: Dysphonia is a common symptom after thyroidectomy. Objective: To analyze the vocal symptoms, auditory-perceptual and acoustic vocal, videolaryngoscopy, the surgical procedures and histopathological findings in patients undergoing thyroidectomy. Methods: Prospective study. Patients submitted to thyroidectomy were evaluated as follows: anamnesis, laryngoscopy, and acoustic vocal assessments. Moments: pre-operative, 1st post (15 days), 2nd post (1 month), 3rd post (3 months), and 4th post (6 months). Results: Among the 151 patients (130 women; 21 men). Type of surgery: lobectomy + isthmectomy n = 40, total thyroidectomy n = 88, thyroidectomy + lymph node dissection n = 23. Vocal symptoms were reported by 42 patients in the 1st post (27.8%) decreasing to 7.2% after 6 months. In the acoustic analysis, f0 and APQ were decreased in women. Videolaryngoscopies showed that 144 patients (95.3%) had normal exams in the preoperative moment. Vocal fold palsies were diagnosed in 34 paralyzes at the 1st post, 32 recurrent laryngeal nerve (lobectomy + isthmectomy n = 6; total thyroidectomy n = 17; thyroidectomy + lymph node dissection n = 9) and 2 superior laryngeal nerve (lobectomy + isthmectomy n = 1; Total thyroidectomy + lymph node dissection n = 1). After 6 months, 10 patients persisted with paralysis of the recurrent laryngeal nerve (6.6%). Histopathology and correlation with vocal fold palsy: colloid nodular goiter (n = 76; palsy n = 13), thyroiditis (n = 8; palsy n = 0), and carcinoma (n = 67; palsy n = 21). Conclusion: Vocal symptoms, reported by 27.8% of the patients on the 1st post decreased to 7% in 6 months. In the acoustic analysis, f0 and APQ were decreased. Transient paralysis of the vocal folds secondary to recurrent and superior laryngeal nerve injury occurred in, respectively, 21% and 1.3% of the patients, decreasing to 6.6% and 0% after 6 months.

ABSTRACT

Abstract Introduction: In hypoparathyroidism, calcium supplementation using calcium carbonate is necessary for the hypocalcemia control. The best calcium carbonate intake form is unknown, be it associated with feeding, juice or in fasting. Objective: The objective was to evaluate the calcium, phosphorus and calcium × phosphorus product serum levels of hypoparathyroidism women after total thyroidectomy, following calcium carbonate intake in three different forms. Methods: A crossover study was carried out with patients presenting definitive hypoparathyroidism, assessed in different situations (fasting, with water, orange juice, breakfast with a one-week washout). Through the review of clinical data records of tertiary hospital patients from 1994 to 2010, 12 adult women (18-50 years old) were identified and diagnosed with definitive post-thyroidectomy hypoparathyroidism. The laboratory results of calcium and phosphorus serum levels dosed before and every 30 min were assessed, for 5 h, after calcium carbonate intake (elementary calcium 500 mg). Results: The maximum peak average values for calcium, phosphorus and calcium × phosphorus product were 8.63 mg/dL (water), 8.77 mg/dL (orange juice) and 8.95 mg/dL (breakfast); 4.04 mg/dL (water), 4.03 mg/dL (orange juice) and 4.12 mg/dL (breakfast); 34.3 mg2/dL2 (water), 35.8 mg2/dL2 (orange juice) and 34.5 mg2/dL2 (breakfast), respectively, and the area under the curve 2433 mg/dL min (water), 2577 mg/dL min (orange juice) and 2506 mg/dL min (breakfast), 1203 mg/dL min (water), 1052 mg/dL min (orange juice) and 1128 mg/dL min (breakfast), respectively. There was no significant difference among the three different tests (p > 0.05). Conclusion: The calcium, phosphorus and calcium × phosphorus product serum levels evolved in a similar fashion in the three calcium carbonate intake forms.


Resumo Introdução: No hipoparatireoidismo, a suplementação de cálcio com carbonato de cálcio é necessária para o controle da hipocalcemia. A melhor forma de ingestão de carbonato de cálcio ainda é desconhecida, seja concomitante com alimentação, no suco ou em jejum. Objetivo: Avaliar os níveis séricos de cálcio, fósforo e produto cálcio-fósforo em mulheres pós-tireoidectomia por hipoparatireoidismo, após a ingestão de carbonato de cálcio em três formas diferentes. Método: Foi realizado um estudo cruzado em pacientes com hipoparatireoidismo definitivo, avaliados em diferentes situações (em jejum, com água, suco de laranja, café da manhã, após washout de uma semana). A revisão dos prontuários dos pacientes de um hospital terciário de 1994 a 2010 identificou 12 mulheres adultas (18-50 anos), diagnosticadas com hipoparatireoidismo definitivo pós-tireoidectomia. Os resultados laboratoriais dos níveis séricos de cálcio e fósforo foram mensurados antes e a cada 30 minutos durante 5 horas, após a ingestão de carbonato de cálcio (cálcio elementar 500 mg). Resultados: Os valores de pico máximo médio de cálcio, fósforo e produto cálcio-fósforo foram 8,63 mg/dL (água), 8,77 mg/dL (suco de laranja) e 8,95 mg/dL (café da manhã); 4,04 mg/dL (água), 4,03 mg/dL (suco de laranja) e 4,12 mg/dL (café da manhã); 34,3 mg2/dL2 (água), 35,8 mg2/dL2 (suco de laranja) e 34,5 mg2/dL2 (café da manhã), respectivamente, e a área sob a curva foi 2.433 mg/dL.min. (água), 2.577 mg/dL.min. (suco de laranja) e 2.506 mg/dL.min. (café da manhã), 1.203 mg/dL.min. (água), 1.052 mg/dL.min. (suco de laranja) e 1.128 mg/dL.min. (café da manhã), respectivamente. Não houve diferença significante entre os três diferentes testes (p > 0,05). Conclusão: Os níveis séricos de cálcio, fósforo e produto cálcio-fósforo evoluíram de forma semelhante nas três formas de ingestão de carbonato de cálcio.

ABSTRACT

Abstract Introduction: Endogenous thyroid-stimulating hormone-stimulated thyroglobulin collected after total thyroidectomy is a useful predictor of better prognosis in patients with differentiated thyroid carcinomas in general, but studies with microcarcinomas are scarce. Objective: To assess whether the first postoperative stimulated thyroglobulin measurement is a prognostic factor in patients with microcarcinoma. Methods: The medical data of 150 differentiated thyroid carcinoma patients were studied retrospectively, and 54 (36%) cases with microcarcinoma were selected. The first postoperative stimulated thyroglobulin (1st stimulated thyroglobulin), measured after thyroidectomy, initial presentation data, and microcarcinomas treatment were assessed regarding outcome. Worse prognosis was defined as neoplasm persistence/recurrence. Results: Persistence/recurrence occurred in 27.8% of the cases. These patients were identified according to the following parameters: receiving more than one 131iodine dose (100% vs. 0%; p < 0.0001); accumulated 131iodine dose (232.14 ± 99.09 vs. 144 ± 33.61 mCi; p < 0.0001); presented active disease in the last assessment (53.3% vs. 0%; p < 0.0001); follow-up time (103.07 ± 61.27 vs. 66.85 ± 70.14 months; p = 0.019); and 1st stimulated thyroglobulin (19.01 ± 44.18 vs. 2.19 ± 2.54 ng/dL; p < 0.0001). After multivariate logistic regression, only the 1stSTg [odds ratio = 1.242; 95% confidence interval: 1.022-1.509; p = 0.029] and follow-up time (odds ratio = 1.027; 95% confidence interval: 1.007-1.048; p = 0.007) were independent predictors of risk of persistence/recurrence. The cutoff point of 1.6 ng/dL for the 1st stimulated thyroglobulin was significantly associated with disease persistence/recurrence [area under the curve = 0.713 (p = 0.019)]. Conclusion: The first stimulated thyroglobulin predicted disease persistence/recurrence in patients with microcarcinoma.


Resumo Introdução: A tireoglobulina estimulada pelo hormônio tireoestimulante endógeno coletada após tireoidectomia total é um preditor útil de melhor prognóstico em pacientes com carcinomas diferenciados de tireoide em geral, mas os estudos com microcarcinomas são escassos. Objetivo: Avaliar se a primeira medida pós-operatória de tireoglobulina estimulada é um fator prognóstico em pacientes com microcarcinoma. Método: Os dados clínicos de 150 pacientes com carcinoma diferenciado de tireoide foram estudados retrospectivamente e 54 (36%) casos com microcarcinoma foram selecionados. A primeira dosagem de tireoglobulina estimulada (1a TgE) pós-operatória, medida após a tireoidectomia, os dados da apresentação inicial e tratamento do microcarcinoma foram avaliados quanto ao resultado. O pior prognóstico foi definido como a persistência/recorrência da neoplasia. Resultados: A persistência/recorrência ocorreu em 27,8% dos casos. Esses pacientes foram identificados de acordo com os seguintes parâmetros: receberam mais de uma dose de iodo131 (100% vs. 0%; p < 0,0001); dose acumulada de iodo131 (232,14 ± 99,09 vs. 144 ± 33,61 mCi; p < 0,0001); apresentou doença ativa na última avaliação (53,3% vs. 0%; p < 0,0001); tempo de seguimento (103,07 ± 61,27 vs. 66,85 ± 70,14 meses; p = 0,019); e 1ªTgE (19,01 ± 44,18 vs. 2,19 ± 2,54 ng/dL; p < 0,0001). Após a regressão logística multivariada, apenas a 1ª TgE [odds ratio = 1.242; intervalo de confiança de 95%: 1,022-1,509; p = 0,029] e tempo de seguimento (odds ratio = 1,027; intervalo de confiança de 95%: 1,007-1,048; p = 0,007) foram preditores independentes de risco de persistência/recorrência. O ponto de corte de 1,6 ng/dL para a 1a TgE foi significativamente associado à persistência/recidiva da doença [área abaixo da curva = 0,713 (p = 0,019)]. Conclusão: A 1ª dosagem sérica de tireoglobulina estimulada previu a persistência/recorrência da doença em pacientes com microcarcinoma.

ABSTRACT

RESUMO Objetivo: Descrever os casos de exenteração orbitária de um hospital terciário brasileiro. Métodos: Estudo retrospectivo, envolvendo pacientes submetidos à exenteração orbitária no Hospital das Clínicas da Faculdade de Medicina de Botucatu, entre os anos de 1993 a 2016. As cirurgias foram realizadas sob anestesia geral, por equipe multidisciplinar composta por oftalmologistas, otorrinolaringologistas e cirurgiões de cabeça e pescoço. Resultados: Foram estudados 14 casos de exenteração orbitária, com média de idade de 63,36 ± 13,18 anos e nove homens (64,3%). Todas cirurgias foram realizadas para tratamento de tumores malignos, sendo mais frequente o carcinoma espinocelular (7 casos - 50,0%). Os sítios primários mais frequentes foram as pálpebras (50,0%), seguida pela conjuntiva (28,6%). A maioria das cirurgias foram do tipo exenteração estendida (57,1%), com cicatrização por granulação espontânea (64,3%). A sobrevida em 1 ano foi de 78,6% e em 5 anos de 71,4%. Conclusão: O carcinoma espinocelular foi a principal causa de indicação de exenteração orbitaria, sendo as pálpebras o sítio primário mais frequente. O procedimento mais realizado foi a exenteração estendida, com a grande maioria alcançando margens livres.


ABSTRACT Objective: To describe causes of orbital exenteration in a Brazilian tertiary hospital. Methods: A retrospective study was done, involving patients submitted to orbital exenteration at the Clinical Hospital of Botucatu Medical School, between the years of 1993 to 2016. The surgeries have been performed under general anesthesia, by a multidisciplinary team, composed by ophthalmologists, otolaryngologists and head and neck surgeons. Results: Fourteen cases of orbital exenteration occurred in the period of the study, with a mean age of 63.36 ± 13.18 years and nine were men (64.3%). All exenteration were due to malignant tumors, being more frequent the squamous cell carcinoma (7 cases - 50.0%). The most common primary sites were the eyelids (50.0%) followed by the conjunctiva (28.6%). The majority of the surgeries was extended exenteration type (57.1%) and most of the reconstructions was made by spontaneous granulation (64.3%). The survivor rate in 1 year was 78,6% and in 5 years was 71.4%. Conclusion: The main cause of orbital exenteration was squamous cell carcinoma and the most frequent primary site was the eyelids. Extended exenteration was necessary for the majority of cases, most of them with free margins.

ABSTRACT

ABSTRACT We conducted a systematic review and meta-analysis of randomized and non-randomized controlled trials that compared pure endoscopic with microscopic transsphenoidal surgery (TSS) in the resection of pituitary tumors. Embase, PubMed, Lilacs, and Central Cochrane were used as our data sources. The outcomes were total tumor resection, achievement of biochemical control of functioning adenomas, hospital stay and surgery complications. The randomized trials were analyzed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Two randomized and three prospective controlled non-randomized studies were included. Two studies, including 68 patients, evaluated total tumor resection and the meta-analysis did not show differences between the groups [RR: 1.45 (95% CI: 0.87, 2.44)]. Three studies involving 65 patients analyzed the achievement of biochemical control and no statistical difference was found [RR: 0.94 (95% CI: 0.7, 1.26)]. All five studies compared the frequency of postoperative complications between intervention and control group and meta-analysis favored for a low rate of postoperative complications in the endoscopic TSS group [(RR: 0.37 (95% CI: 0.16, 0.83)]. Due to the low evidence level and low number of observations, the results of our meta-analysis should not be viewed as a final proof of inferiority or superiority of one approach in relation to the other. More data including higher numbers of observations are needed.

ABSTRACT

Pituitary tumors are responsible for 7 to 17% of all intracranial lesions. Over the past decade, advances in endoscopic microsurgical techniques have resulted in an increasingly aggressive endonasal approach to tumors of the midline skull base. We present our series emphasizing technical nuances of endoscopic endonasal transsphenoidal approach to treat pituitary adenomas.


Tumores hipofisários são responsáveis por 7 a 17% de todas as lesões intracranianas. Durante a última década, avanços nas técnicas microcirúrgicas endoscópicas resultaram no aumento de acessos endonasais agressivos para tumores de base de crânio de linha média. Apresentamos nossa série de casos, com ênfase nos detalhes técnicos do acesso endoscópico endonasal transesfenoidal para o tratamento de tumores da hipófise.

ABSTRACT

OBJETIVO: Avaliar a evolução pós-operatória de pacientes com divertículo faringoesofagiano submetidos aos tratamentos cirúrgico e endoscópico. MÉTODOS: Foram analisados de maneira retrospectiva 36 pacientes com divertículo faringo-esofagiano atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP. Os pacientes foram distribuídos em dois grupos, na dependência do tratamento: grupo 1 (n=24) - diverticulectomia associada á miotomia do cricofaríngeo, através de cervicotomia esquerda; grupo 2 (n=12) - diverticulostomia endoscópica usando grampeador linear. RESULTADOS: A mortalidade operatória foi nula em ambos os grupos. Complicações precoces: grupo 1 - dois pacientes desenvolveram fistula cervical e outros dois, rouquidão; grupo 2 - sem complicações. Complicações tardias: grupo 1 - sem complicações: grupo 2: recidiva da disfagia em quatro pacientes (p=0,01). O seguimento médio foi 33 meses para o grupo 1 e 28 meses para o grupo 2. CONCLUSÃO: Os dois procedimentos foram eficazes na remissão da disfagia. O tratamento cirúrgico apresentou superioridade em relação ao endoscópico, com resolução da disfagia com um único procedimento. O tratamento endoscópico deve ser reservado para os mais idosos e portadores de comorbidades.


OBJECTIVE: To evaluate the postoperative outcome of patients with pharyngoesophageal diverticulum submitted to surgical and endoscopic treatments. METHODS: We retrospectively analyzed 36 patients with pharyngo-esophageal diverticulum treated at the Hospital of the Medical School of Botucatu - UNESP. Patients were divided into two groups, depending on the treatment: group 1 (n = 24): diverticulectomy associated myotomy through a left cervicotomy; group 2 (n = 12): endoscopic diverticulostomy with linear stapler. RESULTS: Operative mortality was zero in both groups. Early complications: group 1- two patients developed cervical fistula and two, hoarseness; group 2 - none. Late complications: group 1 - none; group 2: recurrence of dysphagia in four patients (p = .01). Mean follow-up was 33 months for group 1 and 28 months for group 2. CONCLUSION: Both procedures were effective in remission of dysphagia. Surgical treatment showed superiority to endoscopy, with resolution of dysphagia with a single procedure. Endoscopic treatment should be reserved for the elderly and those with comorbidities.

ABSTRACT

O resultado pós-operatório das tireoidectomias é imputado a fatores relativos ao paciente, à tireopatia e ao cirurgião. OBJETIVO: Analisar a experiência de um serviço quanto a complicações com a tireoidectomia. Desenho do estudo: coorte histórica com corte transversal. MATERIAL E MÉTODO: Foram avaliados os prontuários de 228 pacientes submetidos à tireoidectomia, entre 1991 e 2004. Foram estudadas as complicações transitórias, definitivas e totais, persistência e recidiva da tireopatia de base, em relação a fatores clínico-laboratoriais. RESULTADOS: Ocorreram 34,65% de complicações totais, 18,86% de complicações transitórias (9,21% hipocalcemia, 0,44% paralisia de cordas vocais, 4,82% outras), associadas aos primeiros anos de cirurgia no serviço e queixas compressivas, e 17,98% de complicações definitivas (8,77% hipoparatireoidismo, 1,75% paralisia de cordas vocais, 0,44% rouquidão), associadas à malignidade e cirurgias mais radicais. Houve persistência da doença de base em 17,98% dos casos, associada à idade, e recidiva em 10,96%, associada aos primeiros anos de cirurgia, benignidade e cirurgias menos radicais. CONCLUSÃO: Complicações pós-operatórias se associaram a queixas compressivas, história curta, malignidade e cirurgias mais radicais. A recidiva se associou aos primeiros anos de cirurgia no serviço, tireopatias benignas e cirurgias menos radicais. A persistência da doença se associou à maior idade.


The postoperative outcome of thyroidectomies is related to factors concerning the patient, the thyroid disease, and the surgeon. OBJECTIVES: To analyze a clinic's experience with thyroidectomy complications. Study design: historical cross-sectional cohort study. MATERIALS AND METHODS: We reviewed the charts from 228 patients submitted to thyroidectomy, between 1991 and 2004. Transient, permanent and total complications as well as persistence and recurrence of the basal disease were studied in relation to clinical and laboratory factors. RESULTS: Total complications occurred in 34.65%, transient complications in 18.86% (9.21% had hypocalcemia, 0.44% had vocal cord paralysis), associated with the first postoperative years and pressure complaints, and permanent complications in 17.98% (8.77%: hypoparathyroidism; 1.75%: vocal cord paralysis), associated with malignancy and more radical surgeries. The thyroid disease persisted in 17.98% of the cases, associated with age and recurrence in 10.96%, associated with the first operative years, benign diseases and less radical surgeries. CONCLUSION: The complications were associated with pressure complaints, shorter complaining period, malignancy and more radical surgeries. The recurrence was associated with the first operative years, non-neoplastic thyroid diseases and less radical surgeries. The persistence of disease was associated with older age.

ABSTRACT

São apresentados três raros casos de osteoma do etmóide, com extensão para o quadrante medial da órbita e que apresentavam algumas particularidades que os tornavam ainda mais inusitados, como terem acontecido em mulheres, em faixa etária não usual e com queixa de epífora. Os achados radiográficos foram típicos da afecção e os casos foram operados, com resolução do problema.


We report three rare cases of ethmoid osteoma extending to the medial quadrant of the orbit that had singular particularities, such as occurring in women, at an unusual age group, and complaint of epiphora. The radiographic images were typical of this condition. Patients were submitted to surgery with complete resolution of the disease.

ABSTRACT

O aumento do volume da glândula tireóide pode levar à extensão da glândula para o mediastino (bócio mergulhante). O componente intratorácico pode ocasionar a compressão da traquéia e do esôfago e causar disfagia. Sendo esta um sintoma freqüente no bócio mergulhante e que desaparece após a remoção cirúrgica do mesmo, não encontramos relato de estudo dos efeitos da compressão extrínseca sobre a motilidade esofágica. Esta pesquisa foi realizada com o objetivo de avaliar as alterações da motilidade esofágica dos pacientes com bócio mergulhante utilizando como métodos a eletromanometria esofágica e a videofluoroscopia. Foram avaliados 40 pacientes com bócio mergulhante e divididos em dois grupos: Grupo 1: n = 24 pacientes com bócio mergulhante e queixas disfágicas. Grupo 2: n = 16 pacientes com bócio mergulhante e sem queixas disfágicas. No momento inicial (M1), os pacientes foram submetidos à eletromanometria esofágica e à videofluoroscopia. A eletromanometria permitiu a análise da amplitude da pressão nos esfíncteres superior e inferior do esôfago, amplitude das contrações nos terços proximal e distal do esôfago e porcentagem das contrações esofágicas peristálticas, peristálticas normotensivas e hipotensivas após a deglutição de água. A videofluoroscopia permitiu analisar os efeitos da compressão do bócio sobre o esôfago. A seguir, os pacientes foram submetidos à cirurgia para remoção do tecido tireoideano que comprimia o esôfago. Em um período de 3 a 6 meses após a cirurgia, os exames foram repetidos (M2). A análise estatística dos parâmetros eletromanométrico não demonstrou diferenças entre momentos no grupo, nem entre os grupos nos 2 momentos. Foi observada no pós-operatório da tireoidectomia a normalização da videofluoroscopia em 81,3 por cento dos pacientes do grupo 1 e em 90 por cento daqueles do grupo 2. Não foram encontradas evidências eletromanométricas de alteração da atividade motora do esôfago nos pacientes com bócio mergulhante. As alterações encont...

ABSTRACT

BACKGROUND: The responses of the upper esophageal sphincter to gastroesophageal reflux is controversial. OBJECTIVE: Study the effect of upper esophageal sphincter to the esophageal acid perfusion. METHODS: Thirty adult dogs of both sexes were studied, being submitted to esophageal electromanometry. The pull through technique and continuous infusion of the catheters with distilled water were employed. These exams allowed us to measure the pressure width (mm Hg) and the length (cm) of the upper esophageal sphincter in basal conditions (moment 1). After this first phase the animals were submitted to esophagic infusion, being then divided in three groups, according to the solution used in the infusion and the moment of the study, as follows: Group 1: esophagic infusion with distilled water and electromanometric studies accomplished 15 minutes (moment 2) and 30 minutes (moment 3) of the end of the infusion. Group 2: esophagic infusion with HCl 0.1 N and electromanometric studies accomplished 15 minutes after the end of the infusion (moment 2). Group 3: esophagic infusion with HCl 0.1 N and electromanometric studies accomplished 30 minutes after the end of the infusion (moment 3). RESULTS/CONCLUSIONS: This research was performed to evaluate the esophagic acidification influence on the upper esophageal sphincter. The observed results allowed us to conclude that the acidification of the esophagus did not cause any alteration on the pressure width and on the length of the upper esophageal sphincter
