Methods The search strategy was performed to identify relevant papers from the Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, Google Scholar, China Hospital Knowledge Database, Wangfang Chinese Periodical Database, and VIP Chinese Periodical Database. All papers comparing RLPN with TLPN were included from 2000 to 2015. Two to three reviewers independently screened, evaluated, and extracted the included papers. A Meta-analysis was executed by using Review Manager 5.3 software. The interesting outcomes were tumor size, operating time, estimated blood loss, warm ischaemia time, length of hospital stay, positive margin rate, open conversion rate, overall complication rate, and recurrence rate. Results The literature search obtained 378 papers, then 10 of them were ultimately met the inclusion criteria and included in the systematic review. Finally, 6 of the 10 papers were included in the Meta-analysis. RLPN had significantly less operating time [P = 0.01, mean difference(MD)=-33.68, 95% confidence interval(CI) within(-60.35,-7.01)] and shorter length of hospital stay [P < 0.0001, MD=-1.47, 95% CI within(-2.18,-0.76)] than TLPN. Significant differences were not found between RLPN and TLPN in other outcomes. Conclusions RLPN may be equally safe and be faster than TLPN. Each center can choose a modality according to your own operating habits and experience.展开更多

Due to this, we report a new surgical strategy for the construction of aorto-caval (mesenteric-caval) fistula in a patient with homozygous Antithrombin III (ATIII)-Deficiency. The patient survived postoperatively and only surgical complications grade I and II (Clavien-Dindo classification) were reported after short-term and one year follow-up. After one year, the CT-angiography did not show any caval thrombosis or stenosis and no restriction or occlusion of the fistula. Thus, the mesenteric-caval fistula could be safely performed and resulted in a satisfactory patency.展开更多

Patient demographic characteristics, operative factors, pathology, oncologic outcomes, renal function, and tumor complexity were obtained. Radius of the tumor, exophytic/endophytic properties of the tumor, nearness of tumor to the collecting system, anterior/posterior position, location relative to the polar line(RENAL) nephrometry scores were calculated. nephrometry scores were calculated. The operative approach was determined by the primary surgeon. RESULTS: A total of 91 patients were identified who underwent RALPN for a posterior renal tumor. Fifty-four procedures were performed via the retroperitoneal(RP) approach, and 37 via the transperitoneal(TP) approach. There were no significant differences in patient factors(race, sex, age and body mass index), RENAL nephrometry scores, tumor size, conversion rates, or margin status. Among procedures performed on-clamp, therewas no significant difference in warm ischemia times. Total operative time(180.7 min for RP vs 227.8 min for TP, P < 0.001), robotic console time(126.9 min for RP vs 164.3 min for TP, P < 0.001), and median estimated blood loss(32.5 m L for RP vs 150 mL for TP, P < 0.001) were significantly lower via the RP approach. Off-clamp RALPN was performed for 31(57.4%) of RP procedures vs 9(24.3%) of TP procedures. Oncologic and renal functional outcomes were equivalent.CONCLUSION: The RP approach to RALPN for posterior renal tumors is superior with regard to operative time and blood loss and the ability to be performed off-clamp.展开更多

文摘AIM: To evaluate outcomes of robotic-assisted laparoscopic partial nephrectomy performed for posterior renal tumors via a transperitoneal or retroperitoneal approach.METHODS: Retrospective review was performed for patients who underwent robotic-assisted laparoscopic partial nephrectomy(RALPN) for a posterior renal tumor between 2009-2015. Patient demographic characteristics, operative factors, pathology, oncologic outcomes, renal function, and tumor complexity were obtained. Radius of the tumor, exophytic/endophytic properties of the tumor, nearness of tumor to the collecting system, anterior/posterior position, location relative to the polar line(RENAL) nephrometry scores were calculated. nephrometry scores were calculated. The operative approach was determined by the primary surgeon. RESULTS: A total of 91 patients were identified who underwent RALPN for a posterior renal tumor. Fifty-four procedures were performed via the retroperitoneal(RP) approach, and 37 via the transperitoneal(TP) approach. There were no significant differences in patient factors(race, sex, age and body mass index), RENAL nephrometry scores, tumor size, conversion rates, or margin status. Among procedures performed on-clamp, therewas no significant difference in warm ischemia times. Total operative time(180.7 min for RP vs 227.8 min for TP, P < 0.001), robotic console time(126.9 min for RP vs 164.3 min for TP, P < 0.001), and median estimated blood loss(32.5 m L for RP vs 150 mL for TP, P < 0.001) were significantly lower via the RP approach. Off-clamp RALPN was performed for 31(57.4%) of RP procedures vs 9(24.3%) of TP procedures. Oncologic and renal functional outcomes were equivalent.CONCLUSION: The RP approach to RALPN for posterior renal tumors is superior with regard to operative time and blood loss and the ability to be performed off-clamp.
