ABSTRACT
Objective To explore the clinical effect of Habib 4X bipolar radiofrequency ablation assisted laparoscopic partial nephrectomy without blockage of renal artery for treatment of renal cell carcinoma (RCC).MethodsBetween October 2010 and June 2011, 14 patients with exophytic RCC (T1N0M0) were treated with Laparoscopic Partial Nephrectomy with (LRA) or without (LPN) Habib 4X Bipolar Radiofrequency ablation assisted.The LRA group included 6 patients,and the maximum tumor diameter was 2.1 - 3.5 cm (mean,3.1 cm).The LPN group included 8 patients,and the maximum tumor diameter was 2.0 -3.7 cm (mean,3.0 cm).The operative time,average intra-operative blood loss,postoperative hospital stay and incidence of postoperative complications were recorded.Changes of hemoglobin (Hb),serum creatinine (SCr) and ipsilateral glomerular filtration rate (GFR) before and after operation were analyzed and compared. Results The 14 surgical procedures were successful without conversion to open operation.In LRA group,renal artery blocking was unnecessary,the Hb,SCr and GFR before and after operation were (127 ± 19) g/L vs.(124 ± 19) g/L、(96 ±39) μmol/L vs.(92 ±29) μmol/L and (42 ± 12) ml/min vs.(40 ± 13) ml/min,respectively,and the difference was not significant (P ＞0.05).In LPN group,the renal artery blocking time was 20-52 min (mean,32 min),the Hb,SCr and GFR before and after operations were (130±17) g/L vs.(112±15) g/L,(92 ±31) μ mol/L vs.(110±28)μmol/L and (43 ± 14) ml/min vs.(30 ± 11 ) ml/min respectively,and the difference was significant (P ＜0.05 ).The operative time was ( 86 ± 20) min and ( 112 ± 43 ) min,the estimated blood loss was (94 ± 18)ml and (256 ± 58) ml,and the postoperative hospital stay was (5.0 ± 0.8) d and (7.8 ± 1.2 ) d,respectively.The difference between the two groups was significant (P ＜ O.05).Complications such as bleeding,gross hematuria,and leakage of urine were noted in LRA group. Conclusions Habib 4X Bipolar Radiofrequency ablation assisted LPN without blockage of renal artery is a safe and effective intervention with a relatively low incidence of complications.And it is superior to LPN in operative time,intraoperative blood loss and postoperative recovery.
ABSTRACT
Objective To evaluate the treatment of middle-aged and gerontial serious haemorrhagia nasalis with hypodesis of external carotid artery or anterior ethmoidal arter.Methods A retrospective study was performed to investigate treatment of 16 cases of middle-aged and gerontial serious haemorrhagia nasalis,hypodesis of external carotid artery or anterior ethmoidal arter was underwent according to the location and general condition of all cases.Results Satisfactory results were achieved without obviously complication in 34 cases(94.4%).Conclusion Satisfactory results could be achieved by hypodesis of external carotid artery or anterior ethmoidal arter,to treat middle-aged and gerontial serious haemorrhagia nasalis.
