腹腔镜下根治性前列腺切除术治疗TURP术后偶发前列腺癌的配对分析

目的探讨经尿道前列腺切除术(TURP)后偶发前列腺癌行腹腔镜根治性前列腺切除术(LRP)在外科手术、肿瘤学及尿控等方面的影响。方法回顾性分析自2012年1月至2017年12月北部战区总医院泌尿外科285例接受了LRP治疗的男性患者的临床资料。其中37例患者术前已接受过TURP治疗(TURP组),另外选取37例没有接受过TURP的患者与之配对(对照组)。运用相关统计学方法比较两组患者在围手术期并发症、外科手术、肿瘤及尿控等方面的差异。结果两组患者在年龄、体质指数、血清前列腺特异性抗原(PSA)水平以及术前和术后Gleason评分等方面无统计学差异。TURP组与对照组相比患者出血量较多[(555.4±238.4)vs.(237±111.3)mL,P<0.05]、手术时间较长[(256.7±65.3)vs.(215.2±62.3)min,P<0.05]、输血概率大(5.4%vs.0.0%,P<0.05)、并发症发生率较高(43.2%vs.13.5%,P<0.05)。TURP组的手术阳性切缘率与对照组相比(35.1%vs.24.3%)差异无统计学意义(P=0.353)。手术后12个月的尿控率两组相似,但在3个月时TURP组的尿控率较低(40.5%vs.70.2%)。在平均随访36.5个月后,TURP组和对照组分别有10.8%和8.1%的患者出现生化复发,差异无统计学意义。结论TURP后LRP需要更长的手术时间、失血更多、并发症发生率更高和更差的短期尿控,但两组患者远期肿瘤切除效果及远期尿控没有差异,所以TURP后行LRP的疗效是安全可靠的。     

中性粒细胞和淋巴细胞比值对根治性前列腺切除术患者生化复发的影响

目的探究接受根治性前列腺切除术治疗的患者,其中性粒细胞和淋巴细胞比值(NLR)与生化复发(BCR)的关系。方法回顾性收集2009年1月至2017年12月于四川大学华西医院接受根治性前列腺切除术(RP)的620例前列腺癌患者的临床资料。运用单因素与多因素Cox回归分析、限制性3次样条回归分析和趋势性检验分析NLR与BCR的关系,用分层分析进一步讨论手术入路、肿瘤大小和前列腺特异性抗原(PSA)水平对NLR与BCR关系的影响。结果术前升高的NLR不会导致BCR(P=0.31)。然而,亚组分析显示,在中等PSA水平组中,升高的NLR可导致BCR风险增加(HR=1.12,95%CI:1.04~1.20,P=0.04)。在经腹腔入路手术的患者中,较高的NLR更容易导致BCR(HR=1.05,95%CI:0.99~1.11,P=0.02)。对于那些肿瘤体积中等(HR=1.06,95%CI:0.93~1.20,P=0.03)或较大(HR=1.02,95%CI:0.94~1.10,P=0.03)的患者,BCR风险可随着NLR的升高而增加。结论对于经腹腔入路手术、肿瘤大小中等或较大、中等PSA水平的患者,生化复发风险与NLR呈正相关。     

Redox state of adipose tissue for patients with gastric cancer and its connection with the body mass index and distance from the tumor

Excess body weight has been causally linked to an increased risk of different cancer types, including gastric cancer but the mechanisms underlying this relationship are not well understood. Superoxide generation rate, activity of complex I in electron transport chain of mitochondria, activity of matrix metalloproteinase (MMP-2 and 9) of adipose tissues (AT) of patients with gastric cancer in AT located adjacent to tumor (ATAT) and at a distance of 3 cm (ATD) are measured to follow the connection of the redox state with some of the microenvironment indicators (HIF-1α, CD68, Plin5), body mass index (BMI) and cancer metastasis.Superoxide generation rate in ATAT positively correlates with BMI (r = 0.59, p < 0.05) being 4 times higher than in control (p < 0.05). MMP-2, 9 activities in ATAT positively correlate with BMI (r = 0.67, p < 0.05) being 3.3-4.0 higher than in control (p < 0.05). In ATD a statistically significant increase of MMP-2 activity is found. In ATAT for the group of patients with distant metastasis (M1) the superoxide generation rate, MMP-2, 9 activities are about 2 times higher (p < 0.05) than in the subgroup without distant metastases (M0). M1 is also characterized by the increased values of HIF-1α+ (factor 1.25), CD68+ (factor 1.4) and Plin5+ (factor 2.1) compared to M0 category in tumor tissues (p < 0.05). The results can be used for better understanding the mechanism(s) of symbiosis of tumor and adipose tissues as well as serve as a basis for new therapeutic approaches.

目的分析乳酸清除率(LCR)、脉搏变异指数(PVI)与下腔静脉内径呼吸变异指数(IVCrvi)液体治疗对单肺通气老年全腔镜食管癌根治术患者血流动力学的影响。方法将拟行单肺通气全腔镜食管癌根治术的106例老年食管癌患者随机均分为对照组和观察组。对照组术中给予常规液体治疗,观察组术中给予以LCR、PVI与IVCrvi为目标导向的液体治疗。比较两组术前(T0)、单肺通气前(T1)、单肺通气15 min(T2)、单肺通气1 h(T3)及单肺通气结束时(T4)的心率(HR)、平均动脉压(MAP)、中心静脉压(CVP)、每搏输出量变异度(SVV)和心脏指数(CI)。比较两组液体出入量及药物应用情况。同时记录术前和术后肺功能参数。结果两组各时间点HR比较差异均无统计学意义(P＞0.05),观察组T2~T4时间点MAP、CI和SVV、LCR高于对照组,CVP、PVI、IVCrvi低于对照组(P＜0.05)。观察组单肺通气时间、晶体液用量、总输液量、尿量、出血量及使用去氧肾上腺素占比低于对照组,胶体液用量高于对照组(P＜0.05)。观察组术后第1秒用力呼气量(FEV1)、用力肺活量(FVC)、FEV1/FVC均高于对照组(P＜0.05)。结论以LCR、PVI与IVCrvi为目标导向的液体治疗可稳定单肺通气老年患者全腔镜食管癌根治术患者的血流动力学。     

Definición de continencia y factores pronósticos para la recuperación temprana de la continencia urinaria en la prostatectomía radical robótica con reconstrucción posterior del rabdoesfínter. Análisis post hoc de un ensayo clínico aleatorizado

IntroductionUrinary incontinence after radical prostatectomy (RP) is an adverse event with high impact on patient's quality of life. Nowadays there is no standardized method for urinary continence measurement. Posterior rhabdosphincter reconstruction (PRR) is a surgical step that can improve early urinary continence after RP. Our objective was to analyse different continence definitions and predictors of urinary continence recovery after robot-assisted RP (RARP).Materials and methodsWe conducted a double-blind, randomised controlled trial (NCT03302169) including 152 consecutive patients with localized prostate cancer subjected to RARP. Patients were randomised to single urethrovesical anastomosis (control arm) or PRR before urethrovesical anastomosis (PRR arm). Urinary continence was measured with the EPIC-26 and ICIQ-SF validated questionnaires, and pad use (0-1 pads and no pads), at 7, 15, 30, 90, 180 and 365 days after catheter removal. Prognostic factors for early urinary continence recovery were analysed.Results72 patients were included in the control arm and 80 in the PRR arm. Baseline characteristics were similar between arms, except body mass index, which was higher in PRR arm. “No pad” was the only definition assessing the benefit of PRR at 30 days, 33.8% in PRR arm and 18.1% in control arm, p = 0.022; and at 90 days, 58.8 and 43.1% respectively, p = 0.038. Questionnaires did not detect differences in terms of continence recovery. PRR was the only predictor for early continence recovery, p = 0.03.ConclusionsPRR increased early urinary continence recovery after RARP. Continence definition was critical to assess benefit. The only predictive factor for early continence recovery was PRR.     

La prostatectomía radical retropúbica: control del plexo venoso de Santorini

ObjectiveHistorical review of the procedures and maneuvers described in the literature for the control of Santorini's venous plexus.Material and methodReview of original articles on the design of procedures and maneuvers for the control of the Santorini's venous plexus.ResultsThe control of Santorini's plexus is crucial to reduce blood loss and dissect the prostatic apex. The procedure was first performed by Chute in 1954 and has undergone subsequent modifications by several authors (Reiner and Walsh, Hayashi, Myers, etc.) who have published different maneuvers for its control.ConclusionThere is no ideal procedure or maneuver for the control of the Santorini's plexus.     

Percutaneous cystostomy drainage for early removing urethral catheter in robotic-assisted laparoscopic radical prostatectomy: Improving on patients' discomfort

ObjectiveUrethral catheterization is often a major source of discomfort and pain to a patient after a surgical procedure. To better understand the safety and feasibility of the early removal of urethral Foley catheter after robotic-assisted laparoscopic radical prostatectomy by using percutaneous cystostomy drainage, we collected the related data and present our experience.Patients and methodsThis study involved 20 patients. In the study group (10 patients), we used the percutaneous cystostomy device (PCD) and an 18 French urethral catheter together. The urethral catheter was removed at postoperative day (POD) 3 and the PCD was removed at POD 7. In the control group (10 patients), they had standard urethral catheterization with an 18 French catheter and the catheter was removed at POD 7. Demographic and outcome data were measured and analyzed. Urethral pain was recorded using the visual analog scale.ResultsThe two groups were comparable in terms of age, serum prostate specific antigen level, body mass index, clinical tumor stage, surgical duration, estimated blood loss, and surgical times. The study group had significantly less penile pain in POD 3 and POD 7 (mean visual analog scale: 0.9 vs. 2.2, p < 0.001 at POD 3; 0.1 vs. 1.4, p = 0.002 at POD 7). All patients had good urinary continence within 30 days and no urethra stricture was found during the follow up period.ConclusionThe use of a percutaneous cystostomy device is feasible and safe for the early removal of urethral Foley catheter in robotic-assisted laparoscopic radical prostatectomy to decrease penile pain and patient discomfort.     

Minimal incisions for laparoscopic radical cystectomy with extracorporeal-assisted urinary diversion

ObjectiveLaparoscopic radical cystectomy (LRC) had been used for >10 years. However, longer wound incisions for extracorporeal-assisted urinary diversion decrease the benefits of a laparoscopic approach. In this study, we describe our experience of modified LRC with extracorporeal-assisted urinary diversion using minimal wound incisions.Materials and methodsFrom January 2011 to January 2013, 22 consecutive patients underwent radical cystectomy by a single surgeon. Seven patients underwent open radical cystectomy (ORC), and 15 patients underwent LRC with four-port incisions.ResultsThe LRC group had a significantly lower estimated blood loss (p = 0.005), lower blood transfusion rate (p = 0.004), and lower ileus rate (p = 0.031) than the ORC group. No significant differences were noted in operative time, time to flatus, pain score, overall complication rate, pathological stage, positive surgical margin rate, or lymph node yield (27.6 for LRC and 29.1 for ORC). The 1-year disease free survival rate was 86.7% in the LRC group and 71.4% in the ORC group, and the 1-year overall survival rates were both 100%.ConclusionOur experience shows that LRC with extracorporeal-assisted urinary diversion using minimal incisions is a safe and feasible surgical technique with less blood loss. Further reports with a longer follow-up period and large number of cases are necessary to validate our findings.
