Abstract

:To explore the advantages and limitations of holmium laser resection of the bladder tumor (HOLRBT) versus standard transurethral resection of the bladder tumor (TURBT) in the treatment of non-muscle-invasive bladder cancer (NMIBC), the eligible studies were selected from the following databases: PubMed, Cochrane Library, and Embase. Studies comparing HOLRBT and TURBT for patients with NMIBC were included. The outcomes of interest were time of operation, catheterization and hospitalization, rates of recurrence, and perioperative complications, including obturator nerve reflex, bladder perforation, bladder irritation, and urethral stricture. Results of all data were compared and analyzed by Review Manager 5.3. A total of 9 comparative studies were finally included for this analysis. Pooled data demonstrated that HOLRBT significantly reduced the time to catheterization and hospitalization, the rate of recurrence in 2 years of follow-up, obturator nerve reflex, bladder perforation, and bladder irritation, compared with those in TURBT, respectively. However, no significant difference found between HOLRBT and TURBT in the time of operation, rate of recurrence in 1-year follow-up, and urethral stricture. The results of this research reached that HOLRBT would be a better choice than TURBT for patients with NMIBC.

摘要

: 为了探讨钬激光膀胱肿瘤切除术 (HOLRBT) 与标准经尿道膀胱肿瘤切除术 (TURBT) 治疗非肌层浸润性膀胱癌 (NMIBC) 的优势和局限性,从以下数据库中选择符合条件的研究: PubMed,Cochrane Library,和Embase。纳入了比较HOLRBT和TURBT治疗NMIBC患者的研究。感兴趣的结果是手术时间,导尿和住院,复发率和围手术期并发症,包括闭孔神经反射,膀胱穿孔,膀胱刺激和尿道狭窄。所有数据的结果由Review Manager 5.3进行比较和分析。最终纳入总共9项比较研究用于该分析。汇总数据表明,与TURBT相比,HOLRBT分别显著减少了导尿时间和住院时间、2年随访复发率、闭孔神经反射、膀胱穿孔和膀胱刺激。然而,HOLRBT和TURBT在手术时间、1年随访复发率和尿道狭窄方面无显著差异。本研究结果表明,对于NMIBC患者,HOLRBT将是比TURBT更好的选择。

METHODS::Veterinary educators use models to allow repetitive practice of surgical skills leading to clinical competence. Canine castration is a commonly performed procedure that is considered a Day One competency for a veterinarian. In this study, we sought to create and evaluate a canine pre-scrotal closed castration model and grading rubric using a validation framework of content evidence, internal structure evidence, and relationship with other variables. Veterinarians (n = 8) and students (n = 32) were recorded while they performed a castration on the model and provided survey feedback. A subset of the students (n = 7) then performed a live canine castration, and their scores were compared with their model scores. One hundred percent of the veterinarians and 91% of the students reported that the model was helpful in training for canine castration. They highlighted several areas for continued improvement. Veterinarians' model performance scores were significantly higher than students', indicating that the model had adequate features to differentiate expert from novice performance. Students' performance on the model strongly correlated with their performance of live castration (r = .82). Surgical time was also strongly correlated (r = .70). The internal consistency of model and live rubric scores were good at .85 and .94, respectively. The framework supported validation of the model and rubric. The canine castration model facilitated cost-efficient practice in a safe environment in which students received instructor feedback and learned through experience without the risk of negatively affecting a patient's well-being. The strong correlation between model and live animal performance scores suggests that the model could be useful for mastery learning.

METHODS:PURPOSE:To investigate whether hexaminolevulinate-based (HAL) bladder tumor resection (TURBT) impacts on outcomes of patients with primary non-muscle-invasive bladder cancer (NMIBC) who were eventually treated with radical cystectomy (RC). METHODS:A total of 131 consecutive patients exhibiting NMIBC at primary diagnosis were retrospectively investigated whether they had undergone any HAL-guided TURBT prior to RC. Uni- and multivariable analyses were used to evaluate the impact of HAL-TURBT on cancer-specific (CSS) and overall survival (OS). The median follow-up was 38 months (IQR 13-56). RESULTS:Of the 131 patients, 69 (52.7%) were managed with HAL- and 62 (47.3%) with white light (WL)-TURBT only prior to RC. HAL-TURBT was associated with a higher number of TURBTs prior to RC (p = 0.002) and administration of intravesical chemotherapy (p = 0.043). A trend towards a higher rate of tumor-associated immune cell infiltrates in RC specimens (p = 0.07) and a lower utilization rate of post-operative systemic chemotherapy (p = 0.10) was noted for patients who were treated with HAL-TURBT. The 5-year CSS/OS was 90.9%/74.5% for the HAL-group and 73.8%/55.8% for the WL-group (p = 0.042/0.038). In multivariable analysis, lymph node tumor involvement (p = 0.007), positive surgical margins (p = 0.001) and performance of WL-TURBT only (p = 0.040) were independent predictors for cancer-specific death. CONCLUSIONS:The present data suggest that the resection of NMIBC under HAL exerts a beneficial impact on outcomes of patients who will need to undergo RC during their course of disease. This finding may be due to improved risk stratification as the resection under HAL may allow more patients to be treated timely and adequately.

METHODS:PURPOSE:To investigate the incidence of inguinal hernia following radical prostatectomy we compared the incidence after open retropubic radical prostatectomy with the incidence after the laparoscopic and robot-assisted radical prostatectomies, and using control groups. MATERIALS AND METHODS:We included all original articles on studies providing data on inguinal hernia incidence in patients treated with radical prostatectomy for localized prostate cancer. PubMed® and EMBASE® were searched on February 28, 2018. A meta-analysis was done as a weighted and pooled estimate of the incidence of inguinal hernia. The bias risk was assessed using the Newcastle-Ottawa Scale for cohort studies and the Cochrane Collaboration tool for randomized clinical trials. RESULTS:We included 54 studies with a total of 101,687 patients. The estimated incidence of inguinal hernia was 13.7% (95% CI 12.0-15.4) after open retropubic radical prostatectomy, 7.5% (95% CI 5.2-9.8) after laparoscopic radical prostatectomy and 7.9% (95% CI 5.0-10.9) after robot-assisted laparoscopic radical prostatectomy. In studies comparing the incidence of inguinal hernia after open prostatectomy vs no treatment the incidence was significantly higher in the radical prostatectomy group (11.7%, 95% CI 9.2-14.2 vs 3.3%, 95% CI 2.0-4.6). Two of 3 studies showed a significantly higher incidence after laparoscopic and robot-assisted radical prostatectomies compared with a control group. Most studies of intraoperative inguinal hernia prevention techniques demonstrated a significantly lower inguinal hernia incidence in the experimental group. Inguinal hernias that developed after radical prostatectomy were primarily indirect (81.9%, 95% CI 75.3-88.4). CONCLUSIONS:We found a high incidence of inguinal hernia following radical prostatectomy and hernias were primarily of the indirect type. The highest incidence of inguinal hernia was noted after open radical prostatectomy, followed by laparoscopic and robot-assisted radical prostatectomies. There was no significant difference between the laparoscopic and robot-assisted groups. The incidence of inguinal hernia was significantly higher after open radical prostatectomy than in control groups with some evidence to support the same finding for the laparoscopic and robot-assisted approaches. Promising results have been reported in studies of intraoperative prophylactic surgical techniques to reduce the postoperative incidence of inguinal hernia.
