Alternative approaches to endoscopic ablation for benign enlargement of the prostate: systematic review of randomised controlled trials

Objective To compare the effectiveness and risk profile of newer methods for endoscopic ablation of the prostate against the current standard of transurethral resection.Design Systematic review and meta-analysis.Data sources Electronic and paper records in subject area up to March 2006.Review methods We searched for randomised controlled trials of endoscopic ablative interventions that included transurethral resection of prostate as one of the treatment arms. Two reviewers independently extracted data and assessed quality. Meta-analyses of prespecified outcomes were done using fixed and random effects models and reported using relative risk or weighted mean difference.Results We identified 45 randomised controlled trials meeting the inclusion criteria and reporting on 3970 participants. The reports were of moderate to poor quality, with small sample sizes. None of the newer technologies resulted in significantly greater improvement in symptoms than transurethral resection at 12 months, although a trend suggested a better outcome with holmium laser enucleation (random effects weighted mean difference −0.82, 95% confidence interval 1.76 to 0.12) and worse outcome with laser vaporisation (1.49, −0.40 to 3.39). Improvements in secondary measures, such as peak urine flow rate, were consistent with change in symptoms. Blood transfusion rates were higher for transurethral resection than for the newer methods (4.8% v 0.7%) and men undergoing laser vaporisation or diathermy vaporisation were more likely to experience urinary retention (6.7% v 2.3% and 3.6% v 1.1%). Hospital stay was up to one day shorter for the newer technologies.Conclusions Although men undergoing more modern methods of removing benign prostatic enlargement have similar outcomes to standard transurethral resection of prostate along with fewer requirements for blood transfusion and shorter hospital stay, the quality of current evidence is poor. The lack of any clearly more effective procedure suggests that transurethral resection should remain the standard approach.     

Endoscopic Management of Bladder Diverticula

A 50-year-old man with benign prostatic hyperplasia and urinary retention had a very large diverticulum on the posterior wall of the bladder. The patient was managed with transurethral resection of the prostate and endoscopic fulguration of the bladder diverticulum mucosa using the Orandi technique. There was near-complete resolution of the bladder diverticulum following endoscopic management, obviating the need for bladder diverticulectomy. The patient now empties his bladder, with a postvoid residual < 50 mL and the absence of urinary tract infection after 6-month follow-up. We report the successful treatment of a large bladder diverticulum with endoscopic fulguration to near-complete resolution. This minimally invasive technique is a useful alternative in patients unfit for a more extensive surgical approach.

目的:探讨钬激光和经尿道电切术治疗老年高血压伴前列腺增生的疗效和安全性。方法:回顾性分析2011年1月-2013年1月我科收治的48例患者的临床资料,随机分为两组,每组24例,分别采用经尿道前列腺电切术和激光切除术治疗。观察两组手术时间、术中出血量、住院时间、IPSS和QOL评分及血压变化情况。分别于手术前后应用经直肠超声测量患者前列腺厚度,根据球形体积公式估算前列腺重量。结果:钬激光组手术时间、术中出血量、住院时间明显低于电切组,差异具有统计学意义(P0.05);钬激光组术后前列腺重量、IPSS评分、QOL评分及血压均低于电切组,差异具有统计学意义(P0.05)。结论:经尿道钬激光切除术治疗伴高血压的老年前列腺增生患者安全有效,可在临床推广。     

Comparison of Endoscopic and Open Resection for Small Gastric Gastrointestinal Stromal Tumor

The National Comprehensive Cancer Network recommends conservative follow-up for gastric gastrointestinal stromal tumors (GISTs) less than 2 cm. We have previously reported that the mitotic index of 22.22% of small gastric GISTs exceeded 5 per 50 high-power fields and recommended that all small gastric GISTs should be resected once diagnosed. The aim of the present study is to compare the safety and outcomes of endoscopic and open resection of small gastric GISTs. From May 2010 to March 2014, a total of 90 small gastric GIST patients were enrolled in the present study, including 40 patients who underwent surgical resection and 50 patients who underwent endoscopic resection. The clinicopathological characteristics, resection-related factors, and clinical outcomes were recorded and analyzed. The clinicopathological characteristics were comparable between the two groups except for tumor location and DOG-1 expression. Compared with the surgical resection group, the operation time was shorter (P = .000), blood loss was less (P = .000), pain intensity was lower (P < .05), duration of first flatus and defecation was shorter (P < .05), and medical cost of hospitalization was lower (P = .027) in the endoscopic resection group. The complications and postoperative hospital stay were comparable between the two groups. No in situ recurrence or liver metastasis was observed during follow-up. Endoscopic resection of small gastric GISTs is safe and feasible compared with surgical resection, although perforation could not be totally avoided during and after resection. The clinical outcome of endoscopic resection is also favorable.     

Transurethral resection of large prostates.

A total of 102 men (mean age 70) underwent transurethral resection of the prostate. The weight of the resected prostate ranged from 40 to 152 g. Two deaths occurred in patients aged 85 and 92 years, both of whom were generally unfit. The average postoperative stay in hospital was 8.3 days. The proportions of patients with incontinence, infection, and stricture were similar to those in other series of resections and open prostatectomies, suggesting that resection of the larger prostate is safe and an acceptable alternative to an open operation.

Endoscopic Resection Compared with Gastrectomy to Treat Early Gastric Cancer: A Systematic Review and Meta-Analysis

Background

Endoscopic resection and gastrectomy are treatment modalities for early gastric cancer, but their relative benefits and risks are unclear. We conducted a systematic review and meta-analysis to compare endoscopic resection and gastrectomy for treating early gastric cancer.

Methods

We searched PubMed, Embase, and the Cochrane Library until April 2015 for studies comparing endoscopic resection with gastrectomy for treatment of early gastric cancer. Outcome measures were five-year overall survival (OS), length of hospital stay and postoperative morbidity. We calculated pooled hazard ratio (HR), weighted mean difference (WMD) and odds ratio (OR) using random effects models.

Results

Six studies comprising 1,466 patients (618 endoscopic resection and 848 gastrectomy) met inclusion criteria. Five-year OS was similar between endoscopic resection and gastrectomy (HR, 1.06; 95%CI: 0.61 to 1.83). Endoscopic resection was associated with shorter hospital stays (WMD, -6.94; 95%CI: -7.59 to -6.29) and reduced overall postoperative morbidity (OR, 0.36; 95%CI: 0.17 to 0.74).

Conclusions

While five-year OS is similar between endoscopic resection and gastrectomy, endoscopic resection offers a shorter hospital stay and fewer complications than gastrectomy for treating early gastric cancer. Endoscopic resection is a reasonable treatment for early gastric cancer with a negligible risk of lymph node metastasis.

腹腔镜切除与内镜联合治疗胃肠道肿瘤的效果观察

目的：分析腹腔镜联合内镜治疗胃肠道肿瘤的可行性和临床效果。方法：对我院收治的行腹腔镜切除与内镜联合治疗的75例胃肠道肿瘤患者的临床资料进行回顾性分析,其中腹腔镜与胃镜联合治疗34例,腹腔镜与肠镜联合治疗41例。总结分析治疗效果。结果：75例患者中有72例手术成功,3例患者因肿瘤位置不佳中转开腹,腹腔镜与胃镜联合平均手术时间（72.8±12.7）min,出血量5~30mL,术后无吻合口瘘、吻合口出血、腹腔感染等并发症,住院时间（7.5±0.5）d。结论：腹腔镜联合内镜治疗胃肠道肿瘤具有创伤小、手术安全的特点,是一种有效、安全的治疗手段,值得临床推广应用。     

中鼻甲手术治疗鼻窦炎的临床疗效

为了研究中鼻甲手术处理对治疗患者鼻窦炎的临床疗效,本研究选取2013年3月至2018年3月在我院进行鼻内镜手术的患者400例,根据术中对中鼻甲处理情况分为观察组和对照组,每组200例,观察组行中鼻甲成形术,对照组行中鼻甲切除术;观察2组患者治疗一年后的疗效、Lund-Kennedy评分、主观症状VAS评分、嗅觉变化及并发症。研究显示,观察组的治疗有效率(90.50%)与对照组(88.50%)无显著差异(p=0.514)。两组患者治疗1年后的Lund-Kennedy总评分均显著降低,并且观察组的Lund-Kennedy总评分显著低于对照组(2.24 vs.2.75,p<0.05)。对于Lund-Kennedy评分的各个单项评分,治疗后观察组的息肉、瘢痕和结痂显著低于对照组(p<0.05)。治疗1年后观察组的鼻塞评分显著低于对照组(2.22 vs.3.43,p<0.05),而两组的脓涕评分差异无统计学意义(2.25 vs.2.76,p>0.05)。治疗1年后,两组嗅觉功能评分均显著降低,但两组评分之间差异无统计学意义(1.78 vs.1.81,p>0.05)。两组患者的并发症发生率无统计学差异(p>0.05)。本研究表明,中鼻甲是否切除不影响患者的治疗效果和嗅觉功能,然而,与中鼻甲切除术相比,中鼻甲成形术后患者具有较少的息肉、瘢痕、结痂、鼻腔干燥现象,并且可显著改善鼻塞主观症状。     

Holmium Laser Enucleation versus Transurethral Resection in Patients with Benign Prostate Hyperplasia: An Updated Systematic Review with Meta-Analysis and Trial Sequential Analysis

Background

Holmium laser enucleation (HoLEP) in surgical treatment of benign prostate hyperplasia (BPH) potentially offers advantages over transurethral resection of the prostate (TURP).

Methods

Published randomized controlled trials (RCTs) were identified from PubMed, EMBASE, Science Citation Index, and the Cochrane Library up to October 10, 2013 (updated on February 5, 2014). After methodological quality assessment and data extraction, meta-analysis was performed using STATA 12.0 and Trial Sequential Analysis (TSA) 0.9 software.

Results

Fifteen studies including 8 RCTs involving 855 patients met the criteria. The results of meta-analysis showed that: a) efficacy indicators: there was no significant difference in quality of life between the two groups (P>0.05), but compared with the TURP group, Qmax was better at 3 months and 12 months, PVR was less at 6, 12 months, and IPSS was lower at 12 months in the HoLEP, b) safety indicators: compared with the TURP, HoLEP had less blood transfusion (RR 0.17, 95% CI 0.06 to 0.47), but there was no significant difference in early and late postoperative complications (P>0.05), and c) perioperative indicators: HoLEP was associated with longer operation time (WMD 14.19 min, 95% CI 6.30 to 22.08 min), shorter catheterization time (WMD −19.97 h, 95% CI −24.24 to −15.70 h) and hospital stay (WMD −25.25 h, 95% CI −29.81 to −20.68 h).

Conclusions

In conventional meta-analyses, there is no clinically relevant difference in early and late postoperative complications between the two techniques, but HoLEP is preferable due to advantage in the curative effect, less blood transfusion rate, shorter catheterization duration time and hospital stay. However, trial sequential analysis does not allow us to draw any solid conclusion in overall clinical benefit comparison between the two approaches. Further large, well-designed, multicentre/international RCTs with long-term data and the comparison between the two approaches remain open.     

The treatment of infectious diseases: advances in the use of antimicrobial drugs

Twenty-eight patients with pulmonary tuberculosis in a small, tax-supported sanatorium were treated by primary pulmonary resection. In a comparison of results with those obtained in the same sanatorium by thoracoplasty and extrapleural pneumothorax, it was noted that in general the patients who had resection had earlier conversion of sputum to "negative" and had a shorter stay in hospital. Complications were not of sufficient frequency to contraindicate use of resection in cases in which there was doubt that thoracoplasty would be effective. The cost of hospitalization for surgical treatment and postoperative care was considerably less when resection was done than it was for either three-stage or two-stage thoracoplasty.     

TURP联合经尿道膀胱颈切开术治疗小体积前列腺增生所致膀胱出口梗阻的疗效分析

目的:探讨经尿道前列腺电切术(TURP)联合经尿道膀胱颈切开术(TUIBN)治疗小体积前列腺增生(BPH)所致膀胱出口梗阻的疗效。方法:选择2009年1月~2013年12月我院收治的小体积BPH患者,其中单纯经尿道前列腺电切术(TURP组)48例,经尿道前列腺电切术联合经尿道膀胱颈切开术(TURP+TUIBN组)48例。比较两组的术前、术后国际前列腺症状评分(IPSS)、残余尿量(PVR)、最大尿流率(Qmax)等,以及术后并发症的发生情况。结果:TURP+TUIBN组术中出血量较TURP组明显增多(P0.05),两组手术时间、组织切除质量比较,差异均无统计学意义(P0.05);与TURP组比较,TURP+TUIBN组术后6个月IPSS评分、PVR明显下降,Qmax、膀胱压力明显上升(P0.05);TURP+TUIBN组并发症发生率为4.2%,显著低于TURP组16.7%(P0.05)。结论:TURP+TUIBN治疗小体积前BPH所致膀胱出口梗阻,可彻底切除增生腺体,消除小体积BPH的各种梗阻因素,减少术后膀胱颈挛缩的发生。     

经尿道等离子前列腺剜除术与经尿道前列腺电切术治疗良性前列腺增生症的临床疗效对比研究

摘要 目的：对比经尿道等离子前列腺剜除术（TUKEP）与经尿道前列腺电切术（TURP）治疗良性前列腺增生症（BPH）的临床疗效。方法：回顾性分析我院2018年1月1日至2021年3月17日期间收治的200例BPH患者的临床资料。根据手术方式的不同将患者分为A组（n=83）和B组（n=117）,A组手术方式为TURP,B组手术方式为TUKEP,比较两组围术期指标,随访6个月,对比两组性功能、尿流动力学变化及并发症发生情况。结果：B组手术时间、术中出血量、尿管留置时间、住院时间、术后冲洗时间短于A组（P<0.05）。术后6个月,两组患者的最大尿流速（Qmax）、膀胱顺应性（BC）升高,剩余尿量（PVR）降低（P<0.05）,且B组患者的Qmax、BC高于A组,PVR低于A组（P<0.05）。术后6个月,两组患者的勃起功能评分表（IIEF-5）、射精功能评分表（CIPE-5）评分降低（P<0.05）,但B组、A组IIEF-5、CIPE-5评分组间对比无明显统计学差异（P>0.05）。B组的并发症发生率小于A组（P<0.05）。结论：TUKEP、TURP治疗BPH,疗效相当,TUKEP在缩短手术时间、尿管留置时间、术后冲洗时间、住院时间,降低术中出血量,减少并发症发生率,改善尿流动力学方面更有优势。
