Objective To assess the effect of structured perioperative nutritional optimisation on complication rates, recovery metrics, and body composition in patients undergoing radical cystectomy (RC) with urinary diversion. Patients and Methods In this prospective, randomised controlled trial, 74 patients scheduled for RC were allocated to either a nutritional optimisation group (NOG, n = 37) receiving individualised pre‐ and postoperative dietary interventions, or a standard care group (SCG, n = 37). Protocol included immunonutrition, caloric/protein adjustment, and close clinical and laboratory monitoring. The primary endpoint was overall complication rates within 30 days. Secondary endpoints included time to gastrointestinal recovery, length of hospital stay, wound healing time, nutritional markers, and body composition measurements. Results Baseline characteristics were comparable between the groups. Although the overall complication rate was lower in the NOG (54%) than SCG (68%), the difference was not statistically significant ( P = 0.236). Nutritional optimisation significantly accelerated gastrointestinal recovery; time to flatus (mean [SD] 39.6 [10.2] vs 64.8 [12.4] h, P < 0.001) and stool passage (mean [SD] 63.4 [12.1] vs 84.2 [13.8] h, P = 0.002) were shorter in the NOG. Length of stay (mean [SD] 7.78 [1.13] vs 10.59 [3.67] days, P = 0.002) and wound healing time (mean [SD] 14.22 [0.92] vs 15.5 [0.88] days, P < 0.001) were also significantly improved. The NOG maintained higher skeletal muscle mass and phase angle measurements at 30 days postoperatively ( P ≤ 0.007). Conclusions Structured perioperative nutritional optimisation significantly improved gastrointestinal recovery, reduced hospital stay, accelerated wound healing, and preserved skeletal muscle mass in patients undergoing RC.
目的探讨结构性围手术期营养优化对根治性膀胱切除术(RC)伴尿分流患者并发症发生率、恢复指标和体成分的影响。在这项前瞻性、随机对照试验中,74名计划进行RC的患者被分配到营养优化组(NOG, n = 37)和标准护理组(SCG, n = 37),分别接受个性化的术前和术后饮食干预。方案包括免疫营养,热量/蛋白质调整,密切的临床和实验室监测。主要终点是30天内的总并发症发生率。次要终点包括胃肠道恢复时间、住院时间、伤口愈合时间、营养指标和身体成分测量。结果两组间基线特征具有可比性。虽然NOG组的总并发症发生率(54%)低于SCG组(68%),但差异无统计学意义(P = 0.236)。营养优化显著加速胃肠恢复;NOG组的排气时间(平均[SD] 39.6[10.2]比64.8 [12.4]h, P < 0.001)和排便时间(平均[SD] 63.4[12.1]比84.2 [13.8]h, P = 0.002)更短。住院时间(平均[SD] 7.78 [1.13] vs 10.59[3.67]天,P = 0.002)和伤口愈合时间(平均[SD] 14.22 [0.92] vs 15.5[0.88]天,P < 0.001)也显著改善。术后30天NOG骨骼肌质量和相位角测量值保持较高(P≤0.007)。结论:有组织的围手术期营养优化显著改善了RC患者的胃肠道恢复,缩短了住院时间,加速了伤口愈合,并保留了骨骼肌质量。

Objective To present a novel technique for cystoscopic application of RADA16, a self‐assembling peptide that promotes both haemostasis and healing within the irradiated bladder, and describe its efficacy for intractable haematuria from radiation cystitis. Patients and Methods A total of 15 patients who had failed standard treatment for haematuria from radiation cystitis were offered this novel treatment at Guy's Hospital, London and Cleveland Clinic London, UK between February and October 2024. A standard saline cystoscopy was performed under general anaesthetic and the bladder emptied. CO 2 insufflation of the bladder was performed and the RADA16 deployed over the area of radiation telangiectasia. This was left for 5 min and then the gas evacuated from the bladder. Patients were followed up for a minimum of 3 months for complications and re‐bleeding. Results In all, 14 of the 15 patients had significant reduction in their bleeding at 6 weeks. One patient with ongoing bleeding proceeded to salvage cystectomy. Two patients required further cystodiathermy and RADA16 application within 3 months. No other modified Clavien–Dindo ≥III complications occurred within 3 months. Patients who had a follow‐up cystoscopy within 3 months of application showed significant regression of the radiation‐induced telangiectasia with no evidence of bladder scarring or ureteric orifice obstruction. Conclusions Cystoscopic application of RADA16 shows promise for treating intractable haematuria from radiation cystitis. It is the first treatment option that potentially provides both haemostasis as well as promoting bladder healing and regression of radiation‐induced telangiectasia.

Objectives To assess the feasibility of conducting a multicentre trial comparing NeuroSAFE with a novel technique based on confocal laser microscopy (LaserSAFE) and evaluate the diagnostic performance of LaserSAFE for real‐time surgical margin assessment. Patients and Methods This was a non‐randomised, prospective feasibility study conducted at a high‐volume academic UK centre ( ClinicalTrials.gov identifier: NCT06398470). Patients with localised prostate cancer (clinical T2–T3a N0 M0) scheduled for robot‐assisted radical prostatectomy and deemed unsuitable for bilateral intrafascial nerve sparing (NS) based on a multidisciplinary plan were included. LaserSAFE imaging was performed in the operating room after which the NeuroSAFE technique results guided NS decisions. Pathologists, blinded to NeuroSAFE and final histology, retrospectively evaluated LaserSAFE images. Diagnostic accuracy metrics and concordance between modalities were calculated. Feasibility was assessed based on recruitment rate and the ability to activate additional sites. Results A total of 20 patients were recruited at a single site within 12 months of recruitment start. However, expansion to additional centres was not feasible due to limitations in implementing the NeuroSAFE protocol. LaserSAFE achieved a sensitivity of 0.91 (95% confidence interval [CI] 0.59–1.00) and specificity of 1.00 (95% CI 0.88–1.00) for detecting positive surgical margins ≥0.5 mm. Cohen's kappa demonstrated strong agreement with NeuroSAFE and final pathology. LaserSAFE was completed within a median of 7 min, significantly shorter than the 63 min required for NeuroSAFE. Limitations include the small sample size, single‐centre setting, and lack of intraoperative decision‐making based on LaserSAFE findings. Conclusion While a multicentre study based on NeuroSAFE as a comparison was not achievable, LaserSAFE proved to be a rapid and accurate alternative for intraoperative margin assessment. These findings support the design of a larger trial in which NS decisions are informed by LaserSAFE, with a view to broadening access to real‐time margin assessment.
目的评估开展多中心试验比较NeuroSAFE与基于共聚焦激光显微镜(LaserSAFE)的新技术的可行性,并评估LaserSAFE在实时手术边缘评估中的诊断性能。患者和方法:这是一项在英国一个高容量学术中心进行的非随机、前瞻性可行性研究(ClinicalTrials.gov识别码:NCT06398470)。本研究纳入了计划接受机器人辅助根治性前列腺切除术的局限性前列腺癌患者(临床T2-T3a N0 M0),并基于多学科计划认为不适合双侧筋膜内神经保留(NS)。在手术室进行LaserSAFE成像,之后NeuroSAFE技术结果指导NS决策。病理学家对NeuroSAFE和最终组织学不知情,回顾性评估LaserSAFE图像。计算诊断准确性指标和模式之间的一致性。可行性是根据征聘率和激活其他地点的能力来评估的。结果在招募开始的12个月内,在单个地点共招募了20例患者。然而,由于实施NeuroSAFE方案的限制,扩展到其他中心是不可行的。LaserSAFE检测≥0.5 mm阳性手术切缘的灵敏度为0.91(95%可信区间[CI] 0.59-1.00),特异性为1.00 (95% CI 0.88-1.00)。Cohen的kappa与NeuroSAFE和最终病理结果一致。LaserSAFE的平均完成时间为7分钟,明显短于NeuroSAFE所需的63分钟。局限性包括样本量小,单中心设置,以及缺乏基于LaserSAFE结果的术中决策。结论:虽然基于NeuroSAFE作为比较的多中心研究无法实现,但LaserSAFE被证明是术中边缘评估的快速和准确的替代方法。这些发现支持更大规模试验的设计,在该试验中,NS决策由LaserSAFE提供信息,以扩大实时边际评估的范围。
