ABSTRACT

Introducción: Los feocromocitomas son tumores que se desarrollan a partir de las células cromafines localizadas en la médula suprarrenal, ganglios simpáticos y parasimpáticos. La distinción entre tumores benignos y malignos es compleja, pues no existen marcadores que puedan discriminar esta diferencia con alta sensibilidad y especificidad. Objetivo: Presentar tres casos clínicos de feocromocitoma maligno, diagnosticados y/o tratados en la sala de hospitalización de adultos del INEN. Método: Se revisaron las historias clínicas y se resumieron los datos. Presentación de los casos: Los 3 pacientes eran del sexo masculino, con edades entre 41 y 51 años al diagnóstico del tumor primario. De ellos, dos tenían una hipertensión arterial controlada y el tercero se comenzó a estudiar por crisis paroxísticas de hipertensión; dos tenían antecedentes de diabetes mellitus y no se demostraron evidencias en ningún caso de lesiones en órganos diana por la hipertensión. En los tres pacientes el tumor se localizó en la suprarrenal derecha. Solo en uno de los casos, la etiología maligna fue informada en el estudio anatomopatológico. En los otros dos pacientes, la malignidad se diagnosticó a punto de partida de lesiones metastásicas, años después de la adrenalectomía, en un caso de cadera y en el otro, de pulmón. Conclusiones: El feocromocitoma maligno es una enfermedad infrecuente de la edad mediana y el diagnóstico de su naturaleza es complejo. Se debe sospechar la aparición de enfermedad metastásica ante la reaparición de los síntomas que motivaron el estudio inicial en el paciente, incluso, años después de la adrenalectomía(AU)


Introduction: Pheochromocytomas are tumors developed from chromaffin cells located in the suprarenal medulla, as well as in sympathetic and parasympathetic ganglia. The distinction between benign and malignant tumors is complex, since there are no markers to discriminate this difference with high sensitivity and specificity. Objective: To present three clinical cases of malignant pheochromocytoma, diagnosed and/or treated in the adult hospitalization ward at the National Institute of Endocrinology. Method: The medical records were reviewed and the data was summarized. Case presentation: The three patients were male and aged between 41 and 51 years at the diagnosis of the primary tumor. Of them, two had controlled arterial hypertension and the third began to be studied for paroxysmal hypertension crises; two had a history of diabetes mellitus and no evidence of target-organ lesions due to hypertension was shown in any case. In the three patients, the tumor was located in the right suprarenal gland. Only in one of the cases, malignant etiology was reported in the pathological study. In the other two patients, the malignancy was diagnosed at the starting point of metastatic lesions, years after adrenalectomy: two respective hip and lung cases. Conclusions: Malignant pheochromocytoma is a rare disease that appears at middle age and whose diagnosis is complex, due to its etiological nature. The appearance of metastatic disease should be suspected, given the reappearance of the symptoms that motivated the initial study in the patient, even years after adrenalectomy(AU)

ABSTRACT

Abstract Introduction Laparoscopic adrenalectomy is the treatment of choice of pheochromocytoma. During the first surgical phase (pneumoperitoneum insufflation, tumor and veins handling), there is a risk of hypertensive crisis due to catecholamine release. After tumor excision, patients can suffer relative vasodilation and the residual effect of antihypertensive drugs, which results in arterial hypotension. For that reason, antihypertensive drugs used in the first phase should have a rapid onset of action, short half-life and no residual effect. Methods We report a series of three cases of patients with pheochromocytoma who were treated with laparoscopic adrenalectomy. They all received clevidipine infusion from the beginning of the surgery, before they had presented hypertension, to treat and try to minimize hypertensive peaks. Results In all patients, hypertensive peaks were controlled in a few minutes. After tumor resection, clevidipine infusion was stopped in all cases, and any patient required infusion of vasopressors. Discussion Clevidipine could be a first choice antihypertensive drug in pheochromocytoma surgery. Starting the infusion of clevidipine before the hypertensive peaks could help to make them less pronounced.


Resumen Introducción La adrenalectomía laparoscópica es el tratamiento de elección del feocromocitoma. Durante la primera fase quirúrgica (insuflación de neumoperitoneo, manipulación del tumor y de las venas implicadas), existe el riesgo de que se desencadenen crisis hipertensivas debido a la liberación de catecolaminas. Después de la extirpación del tumor, los pacientes pueden sufrir una vasodilatación relativa y el efecto residual de los fármacos antihipertensivos usados previamente, lo que resulta en hipotensión arterial. Por esa razón, los fármacos antihipertensivos utilizados en la primera fase quirúrgica deben tener rápido inicio de acción, vida media corta y mínimo efecto residual. Métodos Se describe una serie de casos de tres pacientes con feocromocitoma que fueron tratados con adrenalectomía laparoscópica. Todos recibieron infusión de clevidipino desde el comienzo de la cirugía, antes de presentar hipertensión arterial, para así intentar minimizar y tratar rápidamente los posibles picos hipertensivos. Resultados En todos los pacientes los picos hipertensivos se controlaron en pocos minutos. Después de la resección del tumor, la infusión de clevidipino se detuvo en todos los casos y ningún paciente requirió perfusión de vasopresores. Discusión El clevidipino podría ser un fármaco antihipertensivo de primera elección en la cirugía de feocromocitoma. Iniciarlo antes de que ocurran los picos hipertensivos podría ayudar a que sean más leves.

ABSTRACT

Resumen Objetivo Describir el caso clínico de una paciente con neoplasia oncocitica adrenocortical, tratado quirúrgicamente en una clínica de Lima, Perú. Caso clínico Paciente mujer de 26 años ingresa a emergencia por dolor abdominal inespecífico. Se evidencia tumoración de 15x14x12 cm dependiente de glándula suprarrenal izquierda por lo que se decide tratamiento quirúrgico. Al análisis patológico se evidencia neoplasia oncocítica de potencial maligno incierto. Discusión Las neoplasias oncocíticas adrenocorticales son entidades poco frecuentes, con escasos reportes de casos de esta enfermedad. Para clasificarlas, se usa la escala de Weiss modificada. Obtenemos una neoplasia oncocítica de potencial maligno incierto, cuyo tratamiento incluye la cirugía de resección de tumor y observación. Conclusión Considerar a las neoplasias oncocíticas dentro del diagnóstico diferencial de incidentalomas adrenales.


Objective To describe a case report of a oncocytic adrenocortical neoplasm, treated surgically in a clinic in Lima, Peru. Case report A 26-year-old woman is admitted to the emergency due to nonspecific abdominal pain. A tumor measuring 15x14x12 cm dependent on left adrenal gland is evidenced, so surgical treatment is decided. Pathological analysis evidences oncocytic neoplasia of uncertain malignant potential. Discussion Oncocytic adrenocortical neoplasms are rare entities, with few case reports of this disease. To classify them, the modified Weiss scale is used. We obtain an oncocytic neoplasm of uncertain malignant potential, whose treatment includes surgery for tumor resection and observation. Conclusion Consider oncocytic neoplasms within the differential diagnosis of adrenal incidentalomas.

ABSTRACT

Resumen: Introducción: el ganglioneuroma suprarrenal es un tumor benigno excepcional originado en las células nerviosas derivadas de la cresta neural. El objetivo de este trabajo es comunicar un caso clínico de un ganglioneuroma suprarrenal derecho sintomático. Caso clínico: paciente de 37 años, sexo femenino, que consultó por dolor abdominal inespecífico que luego de la valoración imagenológica y estudio funcional hormonal, se diagnosticó una tumoración suprarrenal derecha no funcionante. Con dicho diagnóstico se realizó la adrenalectomía por abordaje convencional retroperitoneal y el estudio anatomopatológico de la pieza diagnosticó un ganglioneuroma. Discusión: los ganglioneuromas habitualmente son asintomáticos y no funcionantes, por lo que su diagnóstico es incidental en un alto porcentaje de casos. Otros se presentan con una sintomatología inespecífica. Su diagnóstico etiológico preoperatorio raramente es realizado y su confirmación es anatomopatológica. Tienen indicación quirúrgica los sintomáticos, los que superan los 6 cm, o persisten dudas diagnósticas de malignidad. El pronóstico es bueno, siendo excepcional la recidiva.


Summary: Introduction: adrenal ganglioneuroma is an exceptional benign tumour which originates from neural crest cells. The study aims to inform about a clinical case of asymptomatic right adrenal ganglioneuroma. Clinical case: 37-year old patient, female, who consulted for non-specific abdominal pain which, after imaging assessment and functional and hormone test was diagnosed with non-functioning tumour of the right adrenal gland. Upon this diagnosis, adrenalectomy using the conventional retroperitoneal approach was performed, and the pathology study of the piece confirmed the diagnosis of ganglioneuroma. Discussion: ganglioneuromas are usually asymptomatic and non-functioning, so diagnosis is incidental in a large percentage of cases. Others present non-specific symptoms. Preoperative etiological diagnosis is rare, and confirmation is usually after pathology study. Symptomatic tumours over 6cm long have an indication of surgery, as well as those suspicious of malignancy. Prognosis is good, relapses being exceptional.

Discussão: os ganglioneuromas geralmente são assintomáticos e não funcionantes por isso seu diagnóstico é acidental em uma alta proporção dos casos. Outros se apresentam com sintomatologia inespecífica. O diagnóstico etiológico pré-operatório raramente é realizado e sua confirmação é feita pela anatomia patológica. Quando são sintomáticos, têm mais de 6 cm ou se persistem dúvidas sobre sua malignidade têm indicação cirúrgica. O prognóstico é bom, e a recidiva é excepcional.

ABSTRACT

ABSTRACT Objective We analyzed the clinical, biochemical, and imaging findings of adrenalectomized patients with Cushing's disease (CD) in order to compare the characteristics of those who developed Nelson's syndrome (NS) versus those who did not develop this complication (NNS), aiming to identify possible predictive factors for its occurrence. Subjects and methods We performed a retrospective review of the clinical records of a group of patients with CD who underwent TBA between 1974 and 2011. Results Out of 179 patients with CD, 13 (7.3%) underwent TBA. NS occurred in 6 of them (46%) after a mean of 24 months from the total bilateral adrenalectomy (TBA). Age at diagnosis, duration of Cushing's syndrome (CS) until TBA, and steroid replacement doses were similar in both groups. Initial urinary cortisol levels (24-hour urinary free cortisol [UFC]) were significantly higher in the NS group than in the NNS group (p = 0.009). Four patients in the NS group and three of those in the NNS group received radiotherapy before TBA (p = 0.26). Three patients in the NS group presented residual tumors before TBA, compared with none in the NNS group (p = 0.04). At 1 year after TBA, the median ACTH level was 476 ng/L (240-1500 ng/L) in the NS group and 81 ng/L (48-330 ng/L) in the NNS group (p = 0.0007). Conclusion In conclusion, a residual tumor before TBA, higher 24-hour UFC at diagnosis, and increasing ACTH levels within 1 year after TBA emerged as predictive factors of development of NS.

ABSTRACT

ABSTRACT Purpose This study aimed to compare perioperative and postoperative results of right and left laparoscopic adrenalectomy (LA), and to evaluate the impact of challenging factors on these outcomes. Materials and Methods A total of 272 patient's medical records that underwent single side LA between October 2006 and September 2017 were retrospectively reviewed. The patients were divided into 2 groups according to operation side. Moreover, pheochromocytoma, metastatic masses and adrenal lesions >5cm in size were considered to be difficult adrenalectomy cases and the outcomes of these cases were compared between two groups. Results 135 patients (49.6%) underwent right LA and 137 patients (50.4%) underwent left LA. Operation time, estimated blood loss (EBL) and hospitalization time were similar between the groups (p=0.415, p=0.242, p=0.741, respectively). Although EBL was higher on the right side than the left (p=0.038) in the first 20 cases, after this learning period has been completed, there was no significant difference between the groups. In patients with pheochromocytoma, metastatic mass and a mass >5cm in size, despite bleeding complications were clinically higher on the right side, this difference was not statistically significant. Conclusions During the learning period of LA, EBL is higher on the right side. Due to the greater risk of bleeding complications on the right side even on the hands of experienced surgeons, extra care and preoperative planning are required in patients with pheochromocytoma, metastatic masses and masses >5cm in size.

ABSTRACT

ABSTRACT Purpose: The purposes of the present study were to evaluate growth rate of nonfunctioning adrenal incidentalomas (AIs) and their development to hormonal hypersecretion on follow-up. Materials and methods: A retrospective study was conducted from the electronic medical records. A total of 314 patients were diagnosed with adrenal tumors between 2000 and 2016. After excluding patients who had overt adrenal endocrine disorders or whose adrenal tumors were clinically diagnosed as metastatic malignancies, we investigated 108 patients with nonfunctioning AIs including characteristics, the treatment, the way of follow-up and pathology. Results: Fifteen patients received immediate adrenalectomy because of the initial tumor size or patient's preference. Pathological examination revealed malignancy in 2 patients. In the remaining 93 patients, radiological examinations were performed periodically. Tumor enlargement of ≥ 1.0cm was observed in 8.6% of the patients who were followed up as nonfunctioning AIs with a median follow-up period of 61.5 months (range: 4-192). Eleven patients underwent adrenalectomy. On the pathological examinations, all of the tumors, which showed a size increase, were diagnosed as benign tumors. Regarding the followed up patients without adrenalectomy, only 2.4% of the patients had tumor enlargement during the prolonged follow-up. Furthermore, none of the patients developed hormonal hypersecretion or clinical signs such as obesity, glucose intolerance or poorly controlled hypertension. Conclusions: Tumor enlargement of AIs did not correlate with malignancy. The value of repeat radiological and hormonal examinations may be limited in the long-term follow-up of patients whose AIs are not enlarged.

ABSTRACT

ABSTRACT Purpose: To investigate risk factors for complications in patients undergoing adrenalectomy. Materials and Methods: A retrospective search of our institutional database was performed of patients who underwent adrenalectomy, between 2014 and 2018. Clinical parameters and adrenal disorder characteristics were assessed and correlated to intra and post-operative course. Complications were analyzed within 30-days after surgery. A logistic regression was performed in order to identify independent predictors of morbidity in patients after adrenalectomy. Results: The files of 154 patients were reviewed. Median age and Body Mass Index (BMI) were 52-years and 27.8kg/m2, respectively. Mean tumor size was 4.9±4cm. Median surgery duration and estimated blood loss were 140min and 50mL, respectively. There were six conversions to open surgery. Minor and major post-operative complications occurred in 17.5% and 8.4% of the patients. Intra-operative complications occurred in 26.6% of the patients. Four patients died. Mean hospitalization duration was 4-days (Interquartile Range: 3-8). Patients age (p=0.004), comorbidities (p=0.003) and pathological diagnosis (p=0.003) were independent predictors of post-operative complications. Tumor size (p<0.001) and BMI (p=0.009) were independent predictors of intra-operative complications. Pathological diagnosis (p<0.001) and Charlson score (p=0.013) were independent predictors of death. Conclusion: Diligent care is needed with older patients, with multiple comorbidities and harboring unfavorable adrenal disorders (adrenocortical carcinoma and pheocromocytoma), who have greater risk of post-operative complications. Patients with elevated BMI and larger tumors have higher risk of intra, but not of post-operative complications.

ABSTRACT

OBJETIVO: Presentar un caso de quiste adrenal (QA) gigante resecado por vía mínimamente invasiva y realizar una revisión narrativa de la literatura disponible al respecto. MATERIALES Y MÉTODOS: Se presenta el caso de un paciente de sexo masculino de 54 años, con una masa retroperitoneal izquierda de crecimiento lento, asintomático, con imágenes y biopsia sugiriendo un QA complejo con sospecha de infiltración renal. Se indica una resección laparoscópica transabdominal. RESULTADOS: Se encuentra como hallazgo intraoperatorio un QA complejo hemorrágico de 9 cm de diámetro, con adherencia a la fascia de Gerota izquierda, logrando exéresis completa del QA por mínima invasión. El paciente evolucionó satisfactoriamente y fue dado de alta al segundo día posoperatorio. Es asintomático en 19 meses de seguimiento. Si bien los QA son benignos, los QA gigantes con crecimiento rápido, sintomáticos o de conversión hemorrágica, pueden ser resecados por adrenalectomía laparoscópica sin aumento de morbimortalidad. DISCUSIÓN: El abordaje laparoscópico de los QA no funcionales gigantes debe ser considerado como el manejo de elección. Es necesaria más evidencia sobre resultados en diferentes abordajes para generar recomendaciones claras. CONCLUSIÓN: Este reporte se suma a la evidencia actual en cuanto al abordaje mínimamente invasivo para QA gigantes hemorrágicos.


OBJECTIVE: Present a giant adrenal cyst (AC) case treated with minimally invasive resection and to perform a narrative literature review available. MATERIAL AND METHODS: A 54 year-old male presents with a left retroperitoneal slow growing mass, no symptoms, with a complex AC evidenced by previous images and mass biopsy, with suspected renal infiltration. A transabdominal laparoscopic resection is indicated. RESULTS: A complex hemorrhagic 9 cm diameter AC was found, with adhesions to left Gerota's fascia. Complete resection of the AC was achieved through minimally invasive approach. The patient had an uneventful clinical recovery and was discharged on the second postoperative day. On 19th month of follow-up is completely asymptomatic. Even though the AC are benign lesions, the symptomatic giant AC, with fast growing ratio, and/or hemorrhagic conversion could be resected though laparoscopic adrenalectomy, with no increased morbidity or mortality. DISCUSSION: The laparoscopic approach for giant non-functional AC should be considered as the standard of care. More evidence is required in terms of surgical approach outcomes to define clear recommendations. CONCLUSION: This report adds to the actual evidence in terms of minimally invasive approach for hemorrhagic giant AC.

ABSTRACT

ABSTRACT CONTEXT: Pancreatic metastases from primary malignant tumors at other sites are rare, constituting about 2% of the neoplasms that affect the pancreas. Pancreatic metastasis from breast cancer is extremely rare and difficult to diagnose, because its clinical and radiological presentation is similar to that of a primary pancreatic tumor. CASE REPORT: A 64-year-old female developed a lesion in the pancreatic tail 24 months after neoadjuvant therapy, surgery and adjuvant radiation therapy for right-side breast cancer (ductal carcinoma). She underwent distal pancreatectomy with splenectomy and left adrenalectomy, and presented an uneventful outcome. The immunohistochemical analysis on the surgical specimen suggested that the lesion originated from the breast. CONCLUSION: In cases of pancreatic lesions detected in patients with a previous history of breast neoplasm, the possibility of pancreatic metastasis should be carefully considered.

ABSTRACT

RESUMO Objetivo: Analisar as características clínicas, laboratoriais e histopatológicas e o percurso até o estabelecimento do diagnóstico e do tratamento de pacientes com carcinoma de suprarrenal (CSR). Métodos: Estudo retrospectivo com 13 pacientes tratados no serviço de oncologia pediátrica do Hospital das Clínicas da Universidade Federal de Minas Gerais (HC-UFMG) entre 2004 e 2015. Resultados: A idade ao diagnóstico variou de 1,0 a 14,8 anos (mediana: 2,0 anos). As manifestações de hipercortisolismo foram identificadas em todos os casos, e as de virilização, em todas as meninas. Todos os pacientes preencheram os critérios de Weiss para diagnóstico histopatológico de CSR. A imuno-histoquímica foi realizada em 61,5% dos casos. A maioria dos pacientes apresentou doença em estádio I (76,9%). Todos foram submetidos à ressecção tumoral total. Dois pacientes (estádios III e IV) receberam quimioterapia associada ao mitotano. O único óbito observado foi do paciente com doença em estádio IV. A probabilidade de sobrevida global para todo o grupo aos 5,0 anos foi de 92,3±7,4%. A mediana de tempo entre o início dos sintomas e o diagnóstico foi de 9,5 meses, e de 6,0 meses entre a primeira consulta e o início do tratamento. Conclusões: A baixa idade ao diagnóstico, o predomínio de casos com doença localizada e a ressecção tumoral completa - com apenas um caso de ruptura de cápsula tumoral - são possivelmente a explicação para a evolução favorável da população estudada. O longo percurso entre o início dos sintomas e o diagnóstico sugere a importância da capacitação dos pediatras para o reconhecimento precoce dos sinais e dos sintomas do CSR.


ABSTRACT Objective: To analyze clinical, laboratory and histopathological features and the path to diagnosis establishment and treatment of patients with adrenal carcinoma (AC). Methods: Retrospective study with 13 patients assisted at the pediatric oncology service of Hospital das Clínicas, Universidade Federal de Minas Gerais, Brazil, between 2004 and 2015. Results: Age at diagnosis ranged from 1.0 to 14.8 years (median: 2.0 years). Manifestations of hypercortisolism were identified in all cases and virilization in all girls. All patients met the Weiss criteria to AC histopathological diagnosis. Immunohistochemistry was performed in 61.5% of the cases. Most patients had stage I disease (76.9%). All subjects were submitted to total tumor resection. Two patients (stages III and IV disease) received chemotherapy associated to mitotane. The only death case was that of a patient with stage IV disease. The probability of overall survival for the entire group up to 5.0 years was 92.3±7.4%. The median time between the onset of symptoms and diagnosis was 9.5 months, and 6.0 months between first visit and start of treatment. Conclusions: Low age at diagnosis, predominance of cases with localized disease and complete tumor resection - with only one case of tumor capsule rupture - can possibly explain the favorable evolution of the studied population. The long period between onset of symptoms and diagnosis highlights the importance of training pediatricians for early recognition of AC signs and symptoms.

ABSTRACT

Adrenocortical carcinoma is a rare type of endocrine malignancy with an annual incidence of approximately 1–2 cases per million. The majority of these tumors secrete cortisol, and a few secrete aldosterone or androgen. Estrogen-secreting adrenocortical carcinomas are extremely rare, irrespective of the secretion status of other adrenocortical hormones. Here, we report the case of a 53-year-old man with a cortisol and estrogen-secreting adrenocortical carcinoma. The patient presented with gynecomastia and abdominal discomfort. Radiological assessment revealed a tumor measuring 21×15.3×12 cm localized to the retroperitoneum. A hormonal evaluation revealed increased levels of estradiol, dehydroepiandrosterone sulfate, and cortisol. The patient underwent a right adrenalectomy, and the pathological examination revealed an adrenocortical carcinoma with a Weiss' score of 6. After surgery, he was treated with adjuvant radiotherapy. Twenty-one months after treatment, the patient remains alive with no evidence of recurrence.

ABSTRACT

PURPOSE: To examine the perioperative surgical and long-term outcomes of laparoscopic partial adrenalectomy (LPA) by comparing the results of laparoscopic total adrenalectomy (LTA). MATERIALS AND METHODS: A total of 132 transperitoneal laparoscopic adrenalectomies were performed for adrenal gland tumor between May 2006 and April 2019. All surgeries were performed by a single surgeon. Seventy patients underwent LTAs and 54 underwent LPAs. The data were collected retrospectively through review of the medical charts. We compared the perioperative and long-term outcomes between the 2 surgical methods. RESULTS: A total of 70 patients, including 4 patients with bilateral tumors, underwent LTA. In contrast, 54 patients, including 4 patients with bilateral masses, underwent LPA. There were no differences between the 2 groups with regard to mean age at presentation, mean tumor size, or postoperative stay. However, the mean operating time was significantly shorter in the LPA group than that of the LTA group. The mean estimated blood loss in the LPA group was significantly higher than that in the LTA group. However, none of the LPA patients required blood transfusion. The biochemical markers and laboratory values normalized postoperatively in all patients with functional adrenal tumors. There was no local recurrence during the follow-up period. CONCLUSIONS: Our data demonstrate that the surgical outcomes and perioperative complications in LPA group are similar to those of LTA. When LPA is performed for small adrenal lesions, most patients remain steroid independent, as well as recurrence-free at long-term follow-up.

ABSTRACT

PURPOSE: Recently, posterior retroperitoneoscopic adrenalectomy (PRA) has been reported to have some advantages over laparoscopic transperitoneal adrenalectomy (LTA). The objectives of this study were to report our experience over 12 years with laparoscopic adrenalectomy for primary hyperaldosteronism (PHA) and to examine surgical outcomes of PRA compared with LTA in patients with PHA. METHODS: The medical records of 527 patients who underwent minimally invasive adrenalectomy, including LTA or PRA, from January 2006 until May 2017 were reviewed at Severance Hospital (Seoul, Korea). Clinicopathologic characteristics and surgical outcomes of 146 patients with PHA who underwent LTA (19 patients) or PRA (127 patients) were analyzed retrospectively by complete chart review. RESULTS: The overall rates of biochemical and clinical cure were 91.1% and 93.1%, respectively. The mean operation time of the PRA group was significantly shorter than that of the LTA group (72.3 ± 24.1 minutes vs. 115.7 ± 69.7 minutes, P = 0.015). The length of hospital stay in the PRA group was significantly shorter than in the LTA group (3.5 ± 1.3 days vs. 4.2 ± 1.6 days, P = 0.029), and the first meal after surgery came earlier in the PRA group (0.3 ± 0.5 days vs. 0.6 ± 0.5 days, P = 0.049). The number of pain-killers used was also significantly smaller in the PRA group (2.3 ± 2.1 vs. 4.3 ± 2.3, P < 0.001). CONCLUSION: PRA offers an alternative or likely superior method for treatment of small adrenal diseases such as PHA, with improved surgical outcomes.

ABSTRACT

Introducción: Los mielolipomas suprarrenales son tumores benignos e infrecuentes, formados por tejido adiposo y hematopoyético. Se consideran incidentalomas porque se diagnostican fortuitamente en estudios de imagen investigando síntomas abdominales o lumbares o en chequeos rutinarios. Son hormonalmente inactivos casi siempre. Se operan si presentan gran tamaño y usualmente se mantienen estables durante su evolución natural. Objetivos: Identificar las características de los mielolipomas suprarrenales y describir su evolución natural. Métodos: Se realizó un estudio descriptivo retrospectivo en 17 pacientes con mielolipomas suprarrenales diagnosticados por tomografía axial computarizada entre enero de 2006 y abril de 2018. Se estudiaron variables clínicas, hormonales y tomográficas al inicio en 17 pacientes y evolutivamente en 5 pacientes no operados. Se utilizaron medidas de resumen para las variables cualitativas (número y porcentajes) y para las cuantitativas (media y desviación estándar). Resultados: La edad promedio fue 52,9 años y la distribución por sexo: 13 mujeres y 4 hombres (razón 3,2:1). Se indicó tomografía axial computarizada en 11 pacientes por síntomas dolorosos. El tamaño promedio fue 5,6 cm. En 8 tumores el diámetro fue de 6 cm y más. En 9 pacientes se realizó adrenalectomía laparoscópica. Durante la evolución natural, que promedió 5 años y 1 mes, una paciente presentó crecimiento de sus dos masas bilaterales; la derecha se extirpó por sobrepasar los 6 cm. Conclusiones: Los mielolipomas suprarrenales fueron benignos, alcanzaron gran tamaño y provocaron síntomas dolorosos. Fueron hormonalmente inactivos en su mayoría. Evolutivamente, el crecimiento fue muy infrecuente y no hubo transformación maligna ni desarrollo de hiperfunción endocrina(AU)


Introduction: Suprarenal myelolipomas are infrequent benign tumors formed by adipose and hematopoietic tissue. They are considered to be incidentalomas because they are found and diagnosed accidentally in imaging studies intended for abdominal or lumbar problems, or in routine checkups. Suprarenal myelolipomas are almost always hormonally inactive. They are operated on when they are large, and they usually remain stable during their natural evolution. Objectives: Identify the characteristics of suprarenal myelolipomas and describe their natural evolution. Methods: A retrospective descriptive study was conducted of 17 patients with suprarenal myelolipomas diagnosed by computerized axial tomography from January 2006 to April 2018. Clinical, hormonal and tomographic variables were analyzed initially in 17 patients and evolutionarily in 5 non-operated patients. Summary measurements were used for qualitative variables (number and percentages) and for quantitative variables (mean and standard deviation). Results: Mean age was 52.9 years and sex distribution was 13 women and 4 men (ratio of 3.2:1). Computerized axial tomography was indicated for 11 patients with pain symptoms. Average size was 5.6 cm. In 8 tumors the diameter was 6 cm or more. Laparoscopic adrenalectomy was performed on 9 patients. During natural evolution, which averaged 5 years and 1 month, one female patient experienced growth of her two bilateral masses, and the one on the right side was removed for it exceeded 6 cm. Conclusions: The study suprarenal myelolipomas were large, benign and caused pain symptoms. Most were hormonally inactive. In evolutionary terms, growth was very infrequent and there was no malignant transformation or development of endocrine hyperfunction(AU)
