          Abstract

          OBJECTIVE: To evaluate the results of the laparoscopic technique in the treatment of adrenal pheochromocytoma. METHOD: Ten patients, 7 men and 3 women, between 10 and 67 years of age (mean 48) with pheochromocytoma underwent transperitoneal laparoscopic adrenalectomy and were evaluated retrospectively, based on clinical, laboratory, and pathological diagnosis. In all cases there was a solid unilateral adrenal tumor, 5 on the left side and 5 on the right side, whose greater diameter varied from 7 to 80 mm (mean 32). Nine of the 10 patients were chronically hypertensive or had already had hypertensive crises. One patient was normotensive, but presented metabolic alterations suggestive of adrenergic hyperfunction. RESULTS: No deaths occurred in this series. There were two (20%) conversions to open surgery, one due to venous bleeding and one due to the difficulty of dissection behind the vena cava in a patient presenting a partially retro-caval tumor. Surgical time in the 8 non-converted cases ranged from 70 to 215 minutes (mean 136). One patient (10%) received blood transfusion, and another (10%) presented two complications - acute renal failure and a subcutaneous infection. Both had been converted to open surgery. None of the non-converted cases was transfused or presented complications. Hospital discharge occurred between the 2nd and 11th post-operative day (mean 3). The pathological exam of the surgical specimens confirmed the diagnoses of pheochromocytoma in all 10 cases, one of them associated with an aldosterone-producing cortical tumor. CONCLUSIONS: Laparoscopic adrenalectomy for selected patients presenting pheochromocytoma is feasible and provides good results.

          OBJETIVO: Avaliar os resultados da utilização da técnica laparoscópica no tratamento do feocromocitoma de supra-renal. MÉTODO: Dez pacientes, sete homens e três mulheres, entre 10 e 67 anos de idade (média 48), com feocromocitoma, foram operados por via laparoscópica transperitoneal e avaliados retrospectivamente, com base nos diagnósticos clínico-laboratorial e anátomo-patológico. Em todos os casos havia um tumor sólido unilateral de supra-renal, cinco à direita e cinco à esquerda, cujo maior eixo variou de 7 a 80 mm (média 32). Nove dos dez pacientes eram hipertensos crônicos ou tinham história de picos hipertensivos. Um paciente era normotenso, mas apresentava alterações metabólicas sugestivas de hiperfunção adrenérgica. RESULTADOS: Nenhum óbito ocorreu na série. Houve duas (20%) conversões para cirurgia aberta, uma por sangramento venoso e uma por dificuldade de dissecção junto à veia cava, cujo paciente apresentava um tumor parcialmente retrocaval. O tempo operatório nos oito casos não-convertidos foi de 70 a 215 minutos (média 136). Um paciente (10%) recebeu transfusão de sangue e outro (10%) apresentou duas complicações - insuficiência renal aguda e infecção de tecido celular subcutâneo. Ambos foram convertidos para cirurgia aberta. Nenhum dos casos não-convertidos recebeu transfusão ou apresentou complicação. A alta hospitalar foi concedida entre o 2º e o 11º PO (mediana 3). O exame anátomo-patológico das peças cirúrgicas confirmou o feocromocitoma em todos esses dez casos, num deles associado a um tumor cortical produtor de aldosterona. CONCLUSÕES: A supra-renalectomia laparoscópica para casos selecionados de feocromocitoma é factível e apresenta bons resultados.

            Laparoscopic adrenalectomy: new gold standard.

            Nearly 600 cases of laparoscopic adrenalectomy have been described in the world literature, documenting the safety and effectiveness of the procedure. Comparative studies have demonstrated the advantages of the laparoscopic approach when compared to traditional open approaches to adrenalectomy, documenting a more rapid and comfortable recovery, shorter hospitalization, and fewer complications. Several techniques of laparoscopic adrenalectomy have been described. We prefer the transabdominal approach in the lateral decubitus position. Herein we report our experience with 28 adrenalectomies using this approach. Indications for adrenalectomy have been hyperaldosteronism (9), hypercortisolism (4), pheochromocytoma (3), incidentaloma (6), metastasis (3), lymphoma (1), angiomyolipoma (1), other (1). Average tumor size was 3.3 cm (1. 4-8.3 cm). Average operative time was 152 minutes (110-210 minutes), with left adrenalectomy taking slightly longer to perform than on the right (156 vs. 145 minutes). There were no intraoperative complications and one conversion to open adrenalectomy for a large metastatic lung cancer found to be invading the liver. One patient experienced left rib pain from a cannula site immediately at the costal margin. There were no other complications. Average length of hospitalization was 2.3 days (1-6 days). With this and others' experience, laparoscopic adrenalectomy has become the gold standard for adrenalectomy. This manuscript reviews the literature on laparoscopic adrenalectomy and describes the transabdominal lateral approach.

              Laparoscopic adrenalectomy: lessons learned from 100 consecutive procedures.

              One hundred consecutive laparoscopic adrenal procedures for a variety of endocrine disorders were reviewed. There was no mortality, morbidity was 12%, and conversions was 3%. During follow-up, none had recurrence of hormonal excess. Laparoscopic adrenalectomy is the procedure of choice for adrenal removal except in carcinoma or masses > 15 cm. The authors evaluate the effectiveness of laparoscopic adrenalectomy for a variety of endocrine disorders. Since the first laparoscopic adrenalectomy was performed in 1992, this approach quickly has been adopted, and increasing numbers are being reported. However, the follow-up period has been too short to evaluate the completeness of these operations. One hundred consecutive laparoscopic adrenal procedures from January 1992 until November 1996 were reviewed and followed for adequacy of resection. Eighty-eight patients underwent 97 adrenalectomies and biopsies. The mean age was 46 years (range, 17-84 years). Indications were pheochromocytomas (n = 25), aldosterone-producing adenomas (n = 21), nonfunctional adenomas (n = 20), cortisol-producing adenomas (n = 13), Cushing's disease (n = 8), and others (n = 13). Fifty-five patients had previous abdominal surgery. Mean operative time was 123 minutes (range, 80-360 minutes), and estimated blood loss was 70 mL (range, 20-1300 mL). There was no mortality, and morbidity was encountered in 12% of patients, including three patients in whom venous thrombosis developed with two sustaining pulmonary emboli. During pheochromocytoma removal, hypertension occurred in 56% of patients and hypotension in 52%. There were three conversions to open surgery. The average length of stay has decreased from 3 days (range, 2-19 days) in the first 3 years to 2.4 days (range, 1-6 days) over the past 16 months. During follow-up (range, 1-44 months), two patients had renovascular hypertension and none had recurrence of hormonal excess. Laparoscopic adrenalectomy is safe, effective, and decreases hospital stay and wound complications. Prior abdominal surgery is not a contraindication. Pheochromocytomas can be resected safely laparoscopically despite blood pressure variations. Venous thrombosis prophylaxis is mandatory. The laparoscopic approach is the procedure of choice for adrenalectomy except in the case of invasive carcinoma or masses > 15 cm.
