Analysis of clinical characteristics of 985 patients with Cushing's syndrome treated with adrenal surgery in a single center / 中华泌尿外科杂志

Objective:To investigate the etiological spectrum, clinical features, and surgical treatment of patients with Cushing's syndrome (CS) who underwent adrenal surgery.Methods:From August 2002 to August 2022, the clinical data of 985 patients with Cushing's syndrome who underwent surgical treatment in the department of urology, Peking Union Medical College Hospital were retrospectively analyzed. There were 210 males and 775 females. The average age was 43.33±13.49 years old. The age of males was older than that of females (45.53±14.39 vs. 42.68±13.16 years, P=0.016). The principle of preoperative surgical method selection for patients in this group was described as follow. For adrenocorticotropin (ACTH) independent CS, adrenal tumor resection was considered for unilateral solitary lesions and unilateral adrenalectomy was considered for unilateral multiple lesions. For bilateral lesions, the larger tumor was removed first, and the contralateral operation was decided according to the follow-up results. Patients with suspicion of cortical cancer are subjected to R0 resection, and open surgery was performed if the tumor diameter is≥6 cm. The clinical characteristics of CS patients were summarized. The clinical symptom characters, etiology spectrum and the corresponding selection principles of surgical methods were analyzed. Results:Among the 985 cases, ACTH-independent CS accounted for 92.8% (914/985), and ACTH-dependent CS accounted for 7.2% (71/985). According to the postoperative pathological results, ACTH-independent CS was the most common, among which adrenal adenoma was the most common 75.94% (748/985), PBMAH 11.37% (112/985), Cushing's disease 4.26% (42/985), PPNAD 3.25% (32/985), EAS 2.94 (29/985), cortical carcinoma 2.23% (22/985). In terms of clinical manifestations, full moon face, bloody face, buffalo back, central obesity and weight gain were more common. The incidence of the above single symptoms was >30%. In terms of hormone secretion, the cortisol level of ACTH-dependent CS patients was significantly higher than that of ACTH-independent CS ( P<0.001). Cortisol [(16.61±6.78) μg/dl] and 24h-UFC [103.65 (59.83, 175.70) μg/24h] in patients with subclinical cortical adenoma were lower than those in other types of patients ( P<0.001). Among the patients with bilateral adenomas, 4 patients underwent simultaneous resection of bilateral adrenal tumors due to severe CS symptoms, and the remaining 74 patients underwent two-stage simple tumor resection, total adrenalectomy or subtotal adrenalectomy according to the size and number of tumors. Of the 22 patients with cortical carcinoma, 2 patients underwent R0 resection after neoadjuvant therapy with mitotane after being diagnosed by needle biopsy due to local infiltration of the tumor. In patients with EAS and Cushing's disease, 62.07% (18/29) and 23.81% (10/42) were treated with simultaneous bilateral target gland resection due to severe CS symptoms, respectively. In 112 cases of PBMAH and 32 cases of PPNAD, the initial treatment was unilateral adrenalectomy or subtotal adrenalectomy, and the follow-up was continued to decide whether to perform contralateral adrenalectomy or subtotal adrenalectomy. Conclusions:The etiological spectrum of CS patients admitted to the urology department is different from that of the overall CS, and is dominated by adrenal disease, and Cushing's disease is rare. Due to the different etiological spectrum, the patient's symptom spectrum is different, and difficulty in squatting and fracture are rare. The main treatment for unilateral adrenal disease is tumor resection or unilateral adrenalectomy. For ACTH-dependent CS in bilateral lesions, bilateral adrenalectomy is recommended, and hormone supplementation is recommended after surgery. For ACTH-independent CS, unilateral adrenalectomy is recommended first, and individualized treatment plans are formulated based on the results of follow-up.

Paraganglioma del cuerpo carotideo: Revisión bibliográfica / Carotid body paraganglioma: Review of the literature

Introducción: Los paragangliomas son tumores neuroectodérmicos que suelen encontrarse adyacentes a estructuras ganglionares autonómicas. El paraganglioma carotídeo es un tumor parasimpático, habitualmente no secretor de hormonas y de bajo potencial maligno. Objetivo: Realizar una revisión de la literatura con conceptos actuales respecto al abordaje clínico y quirúrgico de esta patología. Diseño: Revisión narrativa de la literatura. Materiales y métodos: Se realizó una búsqueda en bases virtuales como Pubmed y Scielo utilizando los términos "paraganglioma" y "tumor del cuerpo carotídeo" con el fin de encontrar documentos actualizados sobre este tema. Resultados: De las fuentes bibliográficas halladas, se depuraron según impacto, población objeto y tiempo de publicación hasta obtener 48 documentos incluyendo artículos de revisión, reportes de caso y libros, de los cuales se sintetizó información sobre el abordaje del paraganglioma del cuerpo carotídeo. Conclusiones: Ante la presencia de una masa cervical lateral debe considerarse la posibilidad de un paraganglioma; la tomografía computada y la resonancia magnética permiten la aproximación diagnóstica y su clasificación inicial, mientras que la angiografía permite el uso de técnicas de embolización selectiva, cuyo uso en estos tumores es controvertido. La cirugía es el único tratamiento curativo y se considera el manejo de elección en la mayoría de los casos, mientras que la radioterapia se indica en aquellos casos de resecciones incompletas o cuando la cirugía está contraindicada.

Introduction: Paragangliomas are neuroectodermal tumors often found adjacent to autonomic ganglion structures. The carotid paraganglioma is a parasympathetic tumor, usually without hormone secretion function and low malignant potential. Objective: To review current concepts regarding the clinical and surgical management of this condition. Design: Narrative review of the literature. Materials and methods: A search was conducted throughout virtual bases such as Pubmed and Scielo using the terms "paraganglioma" and "carotid body tumor" in order to find updated documents on this topic. Results: From the bibliographical sources found, they were depurated by their impact, target population and publication time until 48 papers including review articles, case reports and books; from these literature, information on carotid body paraganglioma was synthesized. Conclusions: In the presence of a lateral neck mass, paraganglioma should be considered; computed tomography and magnetic resonance allows to do a diagnostic approaching and its initial classification, while angiography allows the use of selective embolization techniques, whose use on these tumors is controversial. Surgery is the only curative treatment and is considered the treatment of choice in most cases, while radiation therapy is indicated in cases of incomplete resection or when surgery is contraindicated.

Cirugía laparoscópica de quistes adrenales: resultados de una serie de 18 pacientes / Laparoscopic surgery of adrenal cysts: results of a series of 18 patients

Introduction: Adrenal cysts have an incidence of 0.064 percent to 0.18 percent at autopsy. Aim: To show our experience in 18 patients with an adrenal cyst operated by laparoscopy. Material and Methods: The series consisted of 18 patients operated, in a series of 344 laparoscopic adrenalectomy performed between 1993 and 2011. The age range was 20 to 61 years with an average of 38 years, 11 women and 7 men. Results: Thirteen cysts were left and 5 were right sided. The lesion size varied between 4.5 and 12.5 cm, with an average of 9.2 cm. Eight patients complained of abdominal discomfort and in the remaining 12 patients there were no signs or symptoms of clinical suspicion. The surgery performed was a laparoscopic decortication-marsupialization in 11 patients, laparoscopic adrenalectomy in 8 cases and partial adrenalectomy in 1 case. Mean operative time was 83.1 minutes (30-180 minutes), and mean hospital stay was 36 hours. Intraoperative complications occurred in 2 patients: 1 diaphragm injury and one renal vein injury, repaired in the same surgery. Postoperative complications occurred in 2 patients, both Clavien 3a, treated by conservative management. Conclusion: Small and non-functional lesions require observation. Partial or total laparoscopic adrenalectomy is indicated in large lesions or in functional and suspected malignant lesions.

Introducción: Los quistes suprarrenales tienen una incidencia de 0,064 por ciento a 0,18 por ciento en autopsias. El objetivo de este trabajo es mostrar nuestra experiencia en 18 pacientes portadores de un quiste adrenal operados por vía laparoscópica. Material y Métodos: La serie está constituida por 18 pacientes, de una serie de 344 adrenalectomías laparoscópicas realizadas entre los años 1993 y 2011. El rango de edad fue de 20 a 61 años, con un promedio de 38 años, 11 mujeres y 7 hombres. Resultados: Trece quistes eran del lado izquierdo y 5 del derecho. El tamaño de la lesión varió entre 4,5 y 12,5 cm, con un promedio de 9,2 cm. En 8 pacientes hubo molestias abdominales vagas y en los restantes 12 pacientes no hubo signos ni síntomas de sospecha clínica. La cirugía realizada fue una decorticación-marsupialización laparoscópica en 11 pacientes, adrenalectomía laparoscópica en bloque en 8 casos y adrenalectomía parcial en 1 caso. El tiempo operatorio promedio fue de 83,1 min (30-180 min), y el tiempo medio de hospitalización fue de 36 h. Complicaciones intraoperatorias ocurrieron en 2 pacientes: 1 lesión de diafragma y 1 lesión de vena renal, reparadas en el mismo acto quirúrgico. Complicaciones postoperatorias ocurrieron en 2 pacientes, ambas Clavien 3a y de manejo conservador. Conclusión: Las lesiones pequeñas y no funcionantes requieren observación. La adrenalectomía laparoscópica parcial o total está indicada en lesiones de gran tamaño, con importante compromiso de la glándula o ante la sospecha de lesión funcionante o malignidad.
