Laparoscopic nephro-ureterectomy with endoscopic laser excision of the distal ureter

Twelve patients with total cervical tracheal stenosis were treated by endoscopic laser excision (neodymium:yttrium aluminum garnet or carbon dioxide laser), bronchoscopic dilation, and prolonged stenting with a silicone T-tube. All patients had previous traumatic or prolonged endotracheal intubation requiring a tracheotomy and presented with aphonia as the major complaint. Multiple laser and dilation treatments were necessary in ten patients. Average duration of T-tube placement was 6 months. Excellent results (decannulation and good voice) were achieved in eight patients with a follow-up of 9 months to 6 years. Persistent granulation tissue and some degree of fibrosis were the most common complications (eight of 12 patients). Two patients died of medical complications. A high success rate with this endoscopic technique justifies this approach as our initial therapy, with open surgical techniques reserved for failure.

Synchronous Lesion

Renal cell carcinoma (RCC) uncommonly metastasizes to the ureter and rarely to the contralateral ureter. We describe the presentation of 2 successive contralateral ureteric metastases from RCC in our institution. The first represents the only reported metachronous ureteric deposit on adjuvant sorafenib after laparoscopic radical nephrectomy for RCC. The other presented with a synchronous lesion after radiological work-up. Both lesions were treated with endoscopic excision and laser ablation with preservation of the renal unit and no local recurrence. We report these cases and discuss the literature.

Laser Excision

Sixteen patients with T1 vocal cord squamous cell carcinoma were treated with endoscopic laser excision during a 4-year period. Laser excision was the initial treatment in 11 patients, and it was used to treat 5 patients who had recurrence after radiotherapy. Postoperatively, 13 (81%) of the 16 patients had normal voices. Two patients with persistent postoperative hoarseness had had anterior commissure lesions and previous radiotherapy; the other patient had a subtotal cordectomy. One patient developed a subsequent new lesion 27 months after the initial laser treatment; he was successfully managed with a second endoscopic laser excision. Involvement of the anterior commissure or involvement of the vocal process with minimally invasive disease proved not to be a contraindication to laser excision. The overall results in this small series suggest that laser excision of T1 vocal cord carcinoma is an excellent method of treatment.

One-lung and two-lung high frequency ventilation (HFV) through a 2-mm internal diameter catheter was evaluated in 22 patients during endoscopic laser excision of stenotic lesions of larynx, trachea, and bronchi. High frequency ventilation at 80 to 250 breaths per minute using air during two-lung HFV and using air-oxygen at an inspired oxygen concentration of 25 % during one-lung HFV maintained adequate alveolar ventilation and oxygenation in all patients. The use of HFV through a catheter allowed continuous control of ventilation and provided maximal surgical exposure for endoscopic laser surgery. The continuous outflow of HFV gases through the endoscope also prevented lung contamination with blood and debris. The potential of HFV polyvinylchloride catheter ignition by laser was also evaluated in the laboratory during continuous flow of air-oxygen and oxygen-nitrous oxide. The laser ignited polyvinylchloride tubes in all the mixtures of oxygen and nitrous oxide within 3 to 7 seconds. Oxygen at 30% mixed with nitrogen 70% was safe and all such tubes were not ignited by the laser. The ability of HFV to provide adequate oxygenation during endoscopic laser surgery using air-oxygen at an FiO2 below 30% also avoids the hazard of catheter and airway fire.
