Anatomic landmarks and time management during retroperitoneoscopic radical nephrectomy 总被引:3,自引:0,他引:3
BACKGROUND AND PURPOSE: Retroperitoneoscopy has not been widely considered the preferred approach to laparoscopic radical nephrectomy for cancer, in part because the retroperitoneal anatomic landmarks have not been well defined. The aim of this study is to provide prospective, objective data on retroperitoneoscopic radical nephrectomy with regard to anatomic landmarks and time management of the sequential operative steps. MATERIALS AND METHODS: A uniform database was devised to record predetermined intraoperative parameters prospectively in 18 consecutive retroperitoneoscopic radical nephrectomies. RESULTS: A three- or four-port technique was employed to perform 10 left and 8 right retroperitoneoscopic radical nephrectomies. Initial balloon dilation was routinely performed outside of and posterior to Gerota's fascia. The anatomic landmarks visible immediately on initial insertion of the laparoscope were: psoas muscle in 18 cases (100%), Gerota's fascia in 18 (100%), peritoneal reflection in 15 (83%), ureter and/or gonadal vein in 11 (61%), and renal artery pulsations in 10 (56%). Aortic pulsations were seen in 9 of 10 left (90%) and the inferior vena cava in 2 of 8 right (25%) radical nephrectomies. The mean surgical time was 203 +/- 52.9 minutes (range 105-290 minutes). The sequential operative steps and their individual time breakdowns were: port placement 12 +/- 3.9 minutes, hilar dissection 63 +/- 29.1 minutes, adrenal mobilization 49 +/- 12.1 minutes, specimen mobilization 19 +/- 20.8 minutes, and specimen entrapment and exit 23 +/- 18.2 minutes. When the initial balloon dilation resulted in visibility of four or more anatomic landmarks, the hilar dissection time was significantly shorter (P < 0.001). CONCLUSIONS: Proper development of the retroperitoneal space and identification of adequate anatomic landmarks is important during retroperitoneoscopy. This timed analysis of the sequential operative steps of retroperitoneoscopic radical nephrectomy has served as an important self-assessment tool for us in improving our surgical technique. As a result, our surgical time for retroperitoneoscopic radical nephrectomy has decreased from the earlier 4- to 5-hour range to the current 2- to 3-hour range. 相似文献

PURPOSE: Retroperitoneoscopic radical nephrectomy (RRN) has been performed at Yokohama City University Medical Center since May 2002. Three surgeons have become skilled in performing RRN without major complications. We investigated the outcomes of the surgery and attempt to clarify whether the technique we adopted is suitable to perform this procedure safely. PATIENTS AND METHODS: Between May 2002 and June 2003, 14 patients suspected of renal cell carcinoma underwent retroperitoneoscopic radical nephrectomy at Yokohama City University Medical Center. The surgical procedure is shown below. In a lateral position, a lumbar oblique incision 6 cm long is made to approach the retroperitoneal space. Under direct vision, the ureter is dissected and Gerota's fascia is dissected from the peritoneum and the psoas muscle to signalize the subsequent dissection line. After the dissection, hand port device was attached to the skin and three 12 mm trocars were placed. The subsequent procedures are performed by retroperitoneoscopic surgery with carbon dioxide insufflation. The isolated kidney was removed through the incision that was made initially. We investigated the outcomes of this procedure. RESULTS: The mean surgical duration was 244.4 minutes and mean blood loss was 217.9 ml. Conversion to open surgery was required in one case due to bleeding and in one case due to incomplete management of a small artery. Blood transfusion was not required in any case. There were no major complications during the perioperative period. CONCLUSIONS: The three operators have become skilled in performing RRN safely with this technique. 相似文献

Laparoscopic radical nephrectomy for renal cell carcinoma--transperitoneal anterior approach 总被引:1,自引:0,他引:1
Mizoguchi H Ohno H Emoto A Imagawa M 《Nihon Hinyōkika Gakkai zasshi. The japanese journal of urology》1999,90(12):906-910
PURPOSE: To evaluate the usefulness of transperitoneal anterior approach in laparoscopic radical nephrectomy for patients with renal cell carcinoma. MATERIAL: Ten patients (Eight males and two females) with small renal cell carcinoma less than 7 cm in diameter were treated with laparoscopic radical nephrectomy between June 1997 and May 1999. Clinical stage was T1aN0M0 in 6 cases and T1bN0M0 in 4 cases. METHOD: Of the 10 patients, the initial four received preoperative embolization of the renal artery. Under general anesthesia laparoscopic radical nephrectomy via transperitoneal anterior approach was performed in all patients. This procedure facilitates initiated early access to the renal vessels as does open radical nephrectomy. The kidney was dissected en bloc with Gerota's fascia and delivered from the small skin incision without morcellation. RESULT: Two patients needed conversion to open surgery. The mean operating time of eight patients except for conversion cases was 247 minutes and the mean blood loss was 258 ml. There was no major complication associated with laparoscopic procedure. CONCLUSION: Transperitoneal anterior approach in laparoscopic radical nephrectomy is a suitable and useful procedure for the treatment of small renal cell carcinoma because it enables us to avoid possible tumor manipulation by early access to the renal vessels as open radical nephrectomy. 相似文献

The interrelationship between the lateral and posterior portions of the peritoneum and Gerota's fascia allows them to be separated from each other, permitting ready visualization of the major renal vessels. The posterior relationship between Gerota's fascia and the transversalis fascia overlying the more posterior psoas muscle can be used to advantage in exposing the renal vessels posteriorly. That the fascial layers defining the retroperitoneal spaces might therefore be used in dissecting the renal hilum and vessels in the performance of radical nephrectomy prompted the present investigation. Twenty patients underwent this approach for radical nephrectomy for varying stages of renal cell carcinoma involving either upper, mid, or lower portion of right or left kidney. Postoperative recovery appeared to be shortened because of the lesser interval of ileus than had previously been encountered using a transperitoneal approach. Despite the minimal manipulation of the kidney prior to ligation of the renal vessels, there was no apparent increased tumor dissemination as detected clinically, and experimentally there appeared to be no increase in tumor cells in the venous effluent. Operative time, blood loss, and postoperative complications were comparable to those reported for the transperitoneal approach. This means of performing radical nephrectomy, based on the relationship of fascial layers in the retroperitoneum thus appeared to lend itself to easier dissection as well as lesser postoperative ileus and corresponding shorter hospital stays. 相似文献
