[Surgery without blood transfusion for pheocromocytoma in a Jehovah's Witness patient: a case report].

A 59-year-old woman who identified as a Jehovah's Witness was diagnosed with pheochromocytoma in the left adrenal gland, measuring 11 cm in diameter, during treatment for hypertension. Given her desire to undergo transfusion-less surgery for religious reasons, we obtained fully informed consent and had the patient sign both a transfusion refusal and exemption-from-responsibility certificate and received consent to instead use plasma derivatives, preoperative diluted autologous transfusion and intraoperative salvaged autologous transfusion. To manage anemia and maintain total blood volume, we preoperatively administered erythropoiesis-stimulating agents and alpha 1 blocker, respectively.

[A clinical study of laparoscopic adrenalectomy for pheochromocytoma--analysis of clinical parameters influencing operative time and intraoperative systolic blood pressure].

Purpose: We retrospectively analyzed the preoperative clinical parameters which influence operative time and intraoperative maximum systolic blood pressure in patients undergoing laparoscopic adrenalectomy for pheochromocytoma.

Materials And Methods: Between January 1992 and September 2010, we performed 28 laparoscopic adrenalectomies for pheochromocytoma at Hamamatsu University School of Medicine. These 28 cases were characterized based on the following parameters: body mass index (BMI), tumor size, history of hypertension, preoperative blood pressure, serum concentration of catecholamine, and 24-h urinary excretion of catecholamine metabolite.

Successful treatment for adrenocorticotropic hormone-independent macronodular adrenal hyperplasia with laparoscopic adrenalectomy: a case series.

Introduction: Adrenocorticotropic hormone-independent macronodular adrenal hyperplasia, characterized by bilateral macronodular adrenal hypertrophy and autonomous cortisol production, is a rare cause of Cushing's syndrome. Bilateral adrenalectomy is considered the standard treatment for adrenocorticotropic hormone-independent macronodular adrenal hyperplasia but obliges the patient to receive lifetime steroid replacement therapy subsequently, and may increase the patient's risk of adrenal insufficiency. These circumstances require surgeons to carefully consider operative strategies on an individual basis.

[A case where the tracheotomy tube was burned during Nd-YAG laser cautery treatment for tracheal neoplasm].

For the treatment of the residual tumor above the incision site, laser cautery was scheduled. Artificial ventilation was carried out using a tracheotomy tube, and a laser fiber was inserted orally for tumor ablation. During the procedure, white smoke appeared in the oral cavity.

[Difficult airway management in a man with large pharyngeal tumor].

A 58-year-old man (height 164 cm, weight 64 kg) complained of hoarseness one week prior to admission, and breathing difficulty from the previous day. From endoscopic observation, a pedunculated mass below the glottus was oscillating when breathing. Laryngomicrosurgery and tracheotomy were scheduled to remove the pharyngeal tumor.
