    Adrenalectomía laparoscópica bilateral sincrónica en feocromocitoma bilateral
    (Sociedad de Cirujanos de Chile, 2011) Castillo C., Octavio A.; Campos P., Rodrigo; Henríquez D., Rene; Bravo P., Juan
    Aim: To evaluate 8 cases of bilateral pheochromocytoma and laparoscopic synchronous treatment. Patients and Methods: From May 1999 to May 2010, 8 patients with bilateral pheochromocytoma were found. A complete preoperative workup was done. Results: We perform 8 transperitoneal laparoscopic bilateral synchronous adrenalectomy. There was no open converted procedure. Mean operative time was 184.37 min. (range 95 to 300 min). Mean hospital stay was 3.8 days (range 3 to 5 days). Mean blood loss was 191.25 ml (range 0 to 500 min). In 7 cases the histopathological result was of pheochromocytoma and 1 as a malignant pheochomocytoma based on its histology. Conclusions: With very well establish diagnostic disease, an appropriate anesthetic strategy and as surgical skills, laparoscopic bilateral synchronic adrenalectomy is a feasible and safe surgical technique for bilateral pheochromocytomas.

    Cirugía percutánea de la litiasis renal en la era de la litotripsia extracorpórea: Experiencia en 301 pacientes
    (Sociedad de Cirujanos de Chile, 2010) Castillo C., Octavio A.; Vidal M., Ivar; Campos P., Rodrigo; Sepúlveda T., Francisco; Fonerón V., Alejandro; Feria F., Miguel
    Introduction: Percutaneous renal surgery was introduced more than 20 years ago in urological practice. Extracorporeal Shock Wave Lithotripsy (ESWL) enter the urological scene shortly after. Our objective is to show our experience in percutaneous renal surgery after the introduction of the ESWL in our institution. Material and Methods: Surgical outcomes of 301 patients who underwent percutaneous renal surgery as treatment of renal stones were analyzed. This series begins just before the introduction of ESWL in our unit. Results: Renal pelvis was the most frequent localization with 142 cases (47.2%). There were 51 patients with straghorn calculi. 255 (84.7%) were stone free after one single procedure. Residual fragments were managed with many methods, until only 16 patients (5.4%) had residual fragments. Complications occurred in 26 patients (8.9%). There was no mortality. Conclusions: Percutaneous surgery is an important tool in the management of renal stones. In general, renal stones managed with this procedure, are more complex, however the achievement of good results is possible.

    Nefrectomía simple laparoscópica NOTES y LESS con el uso de instrumentos laparoscópicos estándar: Experiencia inicial en 3 casos
    (Sociedad de Cirujanos de Chile, 2010) Castillo C., Octavio A.; Vidal M., Ivar; Campos P., Rodrigo; Fonerón V., Alejandro; Feria F., Miguel; Sepúlveda T., Francisco
    Introduction: Natural orifice transluminal endoscopic surgery (NOTES) and Laparoendoscopic Single Site Surgery (LESS) are emerging technologies, which allows to performed surgical procedures avoiding any surgical scars. However there are some problems due to the lack of equipment available for these procedures. The aim of these study is to present our initial experience with the transvaginal nephrectomy NOTES and LESS using standard laparoscopic instruments. Material and Methods: Two female patients (23 and 26 years old) with diagnosis of recurrent urinary tract infection and renal atrophy. A laparoscopic simple nephrectomy with transvaginal NOTES assistance was performed, using one access port for the camera and two abdominal work ports of 10 and 3mm. In a third patient (15 years old) a transumbilical LESS nephrectomy was preformed with the use of standard laparoscopic instruments. Results: Average operative time was 110 min (40-200), with an estimated blood loss of 200 cc. There were no perioperative complications and all patients were discharged 36 hours after surgery. Conclusion: Laparoscopic simple nephrectomy with transvaginal NOTES assistance and LESS are technically feasible with the use of standard laparoscopic instruments. Special access trocars and instruments development for this procedure will allow to performed a pure technique without the use of abdominal incisions.

    Ureteroscopia flexible: Experiencia inicial
    (Sociedad de Cirujanos de Chile, 2011) Campos P., Rodrigo; Sepúlveda T., Francisco; Fonerón V., Alejandro
    Background: Flexible ureteroscopy is an increasingly used diagnostic and therapeutic tool for the upper urinary tract. Aim: To report our experience with flexible ureteroscopy. Material and Methods: Analysis of 13 procedures performed to seven males and 6 women aged 30 to 72 years. Results: The indications for flexible ureteroscopy were urinary lithiasis in six patients, a filling defect found in a CAT scan in five, proximal displacement of a double J catheter in one patient and unilateral hematuria in one patient. Lithiasis was managed with extracorporeal lithotripsy using a Holmium laser. Biopsies were obtained from the sites with filling defects; the catheter was extracted using a Dormia basket. In the patient with hematuria, a hemangioma was found and managed with laser excision. No complications were registered. Conclusions: Flexible ureteroscopy is safe and effective.
