Robotic-assisted surgery for benign urological conditions.
(33/125)
Robotic technology for use in surgery has advanced considerably in the past 10 years. This has become particularly apparent in urology where robotic-assisted radical prostatectomy using the da Vinci surgical system (Intuitive Surgical, CA) has become very popular. The use of robotic assistance for benign urological procedures is less well documented. This article considers the current robotic technology and reviews the situation with regard to robotic surgery for benign urological conditions. (+info)
Pediatric robotic-assisted laparoscopy: a description of the principle procedures.
(34/125)
The advent of clinically useful robotic devices to facilitate reconstructive laparoscopic surgery in pediatric urology opens new doors to minimally invasive procedures. Previously limited by the challenge of delicate suturing and reconstruction using conventional laparoscopic instruments, robotic assistance offers a more rapid climb up the learning curve. Initial procedures that have been safely and efficaciously performed with robotic assistance include nephrectomy, partial nephrectomy, pyeloplasty, and antireflux surgeries. These techniques and their outcomes will be reviewed, as well as some of the challenges still posed by this methodology. (+info)
Robotic-assisted laparoscopic radical prostatectomy: an objective assessment and review of the literature.
(35/125)
Robotic-assisted laparoscopic radical prostatectomy (RLRP) has become an accepted treatment option for men with prostate cancer. A search of the available literature through January 2006 was performed to analyze the surgical technique, outcomes data, and other unique issues regarding RLRP. While prospective, randomized trials and long-term data are lacking, short-term data from single institution series have demonstrated outcomes for RLRP that appear to be equivalent to those for open radical prostatectomy (ORP). Although not yet proven, some encouraging data suggest that RLRP may be able to achieve improved cancer control, postoperative urinary control, and erectile function compared to open surgery for prostate cancer. Definite advantages of RLRP over ORP are not yet established. Future studies will determine the role of RLRP in the surgical treatment of men with prostate cancer. (+info)
BACKGROUND AND OBJECTIVES: New technology has allowed us to perform major abdominal and pelvic surgeries with increasingly smaller instruments. The ultimate goal is surgery with no visible scars. Until current technical limitations are overcome, minilaparoscopy-assisted natural orifice surgery (MANOS) provides a solution. The aim of this study was to examine our clinical and experimental experience with MANOS. METHOD: Minilaparoscopic abdominal instruments were used together with a large vaginal port, which was used for insufflation, visual purposes, introduction of operative instruments, and specimen extraction. Minilaparoscopy-assisted intraperitoneal transgastric appendectomy was done in simulators (Lap trainer with SimuVision, Simulab Corp., Seattle, WA). RESULTS: Since 1998, we have used this technique in 100 cases including ovarian cystectomies, oophorectomies, salpingo-oophorectomies, myomectomies, appendectomies, and cholecystectomies. Some oophorectomies were performed after vaginal hysterectomy in cases where vaginal extraction was not possible. In this case series, we had only one complication, a case of postoperative fever after an ovarian cystectomy, which was diagnosed as drug-related fever. Our limited simulator experience showed that MANOS is a feasible technique for performing transgastric appendectomies. CONCLUSION: It may take several years for natural orifice surgery to become standard care. Meanwhile, MANOS could encourage and expedite this process. (+info)
BACKGROUND AND OBJECTIVE: The rare but serious complications of blind Veress needle insertion during laparoscopy include bowel and vascular injury. To reduce these risks, a novel method of open laparoscopy was introduced into our clinical practice, and its efficacy was evaluated. METHODS: This is a retrospective evaluation of a novel 5-mm-open laparoscopic technique in a university hospital-based endoscopy practice in 65 consecutive patients undergoing laparoscopy with a single surgeon. RESULT: A 71% success rate was achieved using the 5-mm open-entry laparoscopic technique. No complications occurred during any of the laparoscopic procedures, but 29% reverted to a standard 5-mm Veress needle technique. The success of the open-entry technique was independent of prior abdominal surgery, subject age, or body mass index (BMI). CONCLUSION: The 5-mm open-entry technique is safe, fast, and cosmetic. It is easily mastered and may be converted to a standard Veress needle technique if peritoneal entry is not achieved. (+info)
Prospective randomized comparison of cutting and dilating disposable trocars for access during laparoscopic renal surgery.
(38/125)
BACKGROUND AND OBJECTIVES: Traditional trocar tip design for laparoscopic access incorporates cutting blades to penetrate the body wall. More recently, trocars applying tissue dilation have been used that create a smaller defect, seldom requiring fascial wound closure. Four 12-mm commercially available single-use trocar designs were evaluated for postoperative pain. METHODS: The 4-trocar types included 2 cutting (single or pyramidal bladed) and 2 dilating trocars (radially or axially dilating) type. Fifty-six patients undergoing transperitoneal laparoscopic renal surgery were randomized and blinded to one of the 4 trocar types. In each case, trocars were placed in a standard "diamond" configuration: three 12-mm study trocars and a lateral 5-mm trocar that served as a reference point for normalizing patients' pain scores. Postoperative pain based on a visual analog scale and complications were assessed. RESULTS: No statistically significant difference existed in pain scores between different trocar types or trocar sites at 3-hour, 24-hour, and 1-week postoperative assessment time points. Eight (4.8%) minor complications occurred: bleeding in 7 (4.2%) and 1 (0.6%) wound infection. The radially dilating trocar had more device malfunction (P<0.05) than did the others. CONCLUSION: All 4 disposable trocars, muscle cutting or dilating type, were safe and yielded similar postoperative pain scores with or without the fascial wound closure after renal laparoscopy.

"Chinese fan spread" distraction technique of laparoscopic reduction of intussusception.
(39/125)
OBJECTIVE: The "Chinese Fan Spread" (CFS) distraction technique for laparoscopic reduction of intussusception is herein described and its outcome and benefits are evaluated. METHODS: A retrospective review was performed of all patients who underwent attempts at laparoscopic reduction of intussusception at our center. The CFS distraction technique was consistently applied in all cases. RESULTS: Fourteen patients were identified. Median age was 2.4 years (range, 4 months to 10.3 years). Indications for surgery included (1) failed pneumatic reduction (n=11), (2) need to evaluate for lead point in a patient with 4 recurrences (n=1), (3) need to biopsy the lead point in a patient with suspected lymphoma (n=1), and (4) diagnostic laparoscopy for evaluation of hematochezia (n=1). Two patients who failed laparoscopic reduction by the CFS distraction technique also failed open manual reduction, requiring right hemicolectomy. Of the 12 (86%) who were successfully reduced laparoscopically, pathologic lead points were identified in 5 (2 acute appendicitis, 1 Meckel's diverticulum, 1 harmatomatous polyp, and 1 Burkitt's lymphoma). Lead points were excised laparoscopically or via a vertical transumbilical incision. There were no complications. CONCLUSION: Laparoscopic reduction of intussusception by the CFS distraction technique is effective and safe. Lead points may be dealt with together either laparoscopically or via a transumbilical incision. (+info)
Rupture of the spleen with the harmonic scalpel: case report of an unexplained complication.
(40/125)
A 69-year-old female patient underwent a standard laparoscopic Nissen fundoplication for repair of a hiatal hernia and correction of reflux. A Harmonic scalpel was used as the only energy source intraoperatively. The operation was uneventful until the middle of the procedure when a significant amount of blood was noted in the left upper quadrant. After aspiration and careful inspection, a 5-cm irregular vertical laceration was found on the posterior and lateral aspect of the spleen, far away from the operative field and any previous instrumentation. Control of bleeding from the spleen was unsuccessful, so a laparoscopic splenectomy was performed, and the procedure was finished without further incident. Histologic examination revealed a normal spleen with no pathologic alterations accounting for the laceration. After comprehensive evaluation of this case to assess a potential cause of the complication, the question arose as to whether the energy produced by the Harmonic scalpel could have caused this splenic laceration.
