Complete robotic-assistance during laparoscopic living donor nephrectomies: An evaluation of 38 procedures at a single site

INTERNATIONAL JOURNAL OF UROLOGY, Issue 11 2007
Jacques Hubert
Objective: To evaluate our initial experience with entirely robot-assisted laparoscopic live donor (RALD) nephrectomies. Methods: From January 2002 to April 2006, we carried out 38 RALD nephrectomies at our institution, using four ports (three for the robotic arms and one for the assistant). The collateral veins were ligated, and the renal arteries and veins clipped, after completion of ureteral and renal dissection. The kidney was removed via a suprapubic Pfannenstiel incision. A complementary running suture was carried out on the arterial stump to secure the hemostasis. Results: Mean donor age was 43 years. All nephrectomies were carried out entirely laparoscopically, without complications and with minimal blood loss. Mean surgery time was 181 min. Average warm ischemia and cold ischemia times were 5.84 min and 180 min, respectively. Average donor hospital stay was 5.5 days. None of the transplant recipients had delayed graft function. Conclusions: Robot-assisted laparoscopic live donor nephrectomy can be safely carried out. Robotics enhances the laparoscopist's skills, enables the surgeon to dissect meticulously and to prevent problematic bleeding more easily. Donor morbidity and hospitalization are reduced by the laparoscopic approach and the use of robotics allows the surgeon to work under better ergonomic conditions. [source]

Modified radiofrequency-assisted liver resection: A new device

JOURNAL OF SURGICAL ONCOLOGY, Issue 3 2007
Dimitris Zacharoulis MD
Abstract Background Radiofrequency ablation (RF) is emerging as new therapeutic method for the management of hepatic tumors. So far the RF-assisted hepatectomy has been described using an electrode initially designed for ablation of unresectable tumors. Herein, we describe a new technique for liver resection using a bipolar radiofrequency device. Method Ten patients undergo liver resection using a bipolar radiofrequency device. A minimal zone of desiccation around the tumor is created between pairs of opposing electrodes as a result of a minimum amount of energy released. This coagulated plane can be divided with a scalpel. Results The liver parenchyma was divided with minimal blood loss. No intensive care unit admission was needed. There was no postoperative biliary leak or any other septic complication. Conclusion The technique is safe and feasible, simplifies liver resection and appears to be associated with minimal morbidity and maximum liver parenchyma preservation. J. Surg.

Single-port laparoscopic right colonic resection

ANZ JOURNAL OF SURGERY, Issue 1-2 2010
Anil Keshava
Abstract Background:, The laparoscopic approach is a recognized treatment option for colonic resection. We present the first single-port operation for colonic resection using standard laparoscopic equipment and techniques. Methods:, A single-port laparoscopic right colonic resection was successfully performed using GelPort (Applied Medical, Orange County, CA, USA) and a standard laparoscopic approach. Results:, The procedure was completed in 105 min through a single periumbilical incision. There was minimal blood loss and no post-operative problems. Conclusion:, Single-port laparoscopic techniques can be applied to colonic surgery. It negates morbidity associated with trochar insertion and port sites. It should be performed by surgeons familiar with laparoscopic colorectal techniques. [source]

Uterine perfusion following laparoscopic clipping of uterine arteries at myomectomy

Laparoscopic clipping of uterine arteries facilitates laparoscopic myomectomy with minimal blood loss. This paper shows the return to normal myometrial perfusion following this procedure with literary evidence of the safety and efficacy of this technique. [source]

Rotoresect for bloodless transurethral resection of the prostate: a 4-year follow-up

BJU INTERNATIONAL, Issue 1 2003
M.S. Michel
OBJECTIVE To report the results and long-term follow-up of transurethral resection of the prostate (TURP) with a new resection device, the Rotoresect (Karl Storz, Tuttlingen, Germany). PATIENTS AND METHODS Most endoscopic resection techniques for benign prostatic tissue aim for high ablation rates and minimal bleeding. Available resection electrodes are effective, but cause high blood loss (loop electrode), or less bleeding but poorer ablation rates (electrovaporization). To resolve these conflicts the Rotoresect was developed in 1995; it consists of a specially designed rotating resection electrode, driven by a micromotor, and a high-frequency current to enable simultaneous coagulation, vaporization and mechanical tissue removal during resection. To date, 84 patients with benign prostatic hyperplasia have had their prostate resected with this device (mean prostate size 46.0, sd 18.4 mL) and have been assessed for up to 4 years. RESULTS During resection there was very little bleeding, with no significant changes in haemoglobin or sodium levels. The mean (sd) duration of catheterization was 1.4 (1.1) days; the urinary peak flow rate was improved from 9.7 (3.2) to 24.2 (8.23) mL/s and the residual urine volume reduced from 187.3 (109.6) to 22.7 (19.5) mL. The International Prostate Symptom Score and quality-of-life index were both improved, from 24.0 (7.5) to 4.1 (2.7), and 4.2 (3.2) to 0.8 (0.9), respectively. Overall the results were stable during the 4 years of follow-up. CONCLUSION The Rotoresect combines the advantages of standard resection (high ablation rate) by actively rotating the resection electrode, and the haemostatic effect of electrovaporization (minimal blood loss) by simultaneous tissue coagulation and vaporization.

Temporal Approach for Resection of Juvenile Nasopharyngeal Angiofibromas,

THE LARYNGOSCOPE, Issue 8 2000
J. Dale Browne MD
Abstract Objective To describe a lateral preauricular temporal approach for resection of juvenile nasopharyngeal angiofibroma (JNA). Study Design A retrospective review of five patients with JNA tumors that were resected by a lateral preauricular temporal approach. Methods The medical records of five patients who underwent resection of JNA tumors via a lateral preauricular temporal approach were reviewed, and the following data collected: tumor extent, blood loss, hospital stay, and surgical complications. Results Five patients with JNA tumors had resection by a lateral preauricular temporal approach. These tumors ranged from relatively limited disease to more e-tensive intracranial, e-tradural tumors. Using the staging system advocated by Andrews et al., 1 these tumors included stages II, IIIa, and IIIb. Four patients (stages II, IIIa, IIIa, and IIIb) who underwent primary surgical excision had minimal blood losses and were discharged on the first or third postoperative day with minimal transient complications (mild trismus, frontal branch paresis, serous effusion, and cheek hypesthesia). The remaining patient (stage IIIb) did well after surgery, despite having undergone preoperative radiation therapy and sustaining a significant intraoperative blood loss. There have been no permanent complications or tumor recurrences. Conclusions A lateral preauricular temporal approach to the nasopharynx and infratemporal fossa provides effective exposure for resection of extradural JNA tumors. The advantages of this approach include a straightforward route to the site of origin, the absence of facial and palatal incisions, and avoidance of a permanent ipsilateral conductive hearing loss.
