Is ‘Omega Sign’ anatomical endoscopic enucleation of the prostate technique reproducible?

We aimed to evaluate the learning curve of the surgically standardised ‘Omega Sign’ anatomical endoscopic enucleation (AEEP) of the prostate surgery technique for junior surgeons. This study is a retrospective comparison of cases that underwent AEEP by a mentor surgeon and three junior surgeons who have completed their learning curve. A video-based laser enucleation of the prostate assessment tool (LEAT) composed of 8 steps of the technique was used to assess a senior surgeon and junior surgeons’ surgical compatibility and consistency. The surgeon who defined Omega Sign technique was determined as group 1, and cases by three junior surgeons were identified as group 2. The end points were to assess the reproducibility and repeatability and operative post-operative outcomes of the technique. 55 patients’ videos were rated by five experienced endourologists. There was no significant difference in LEAT scores between the groups among all steps. The most symmetry was found in the 1st and 3rd steps. Inter-rater consistency was also high for each step, with no statistically significant difference between the evaluators. The standardised anatomical ‘Omega Sign’ technique is reproducible for the junior surgeons. The operative steps can be performed with high consistency, and the functional and perioperative outcomes are comparable with the senior surgeon.     

经椎间孔入路全内镜下腰椎椎体间融合技术研究进展

经椎间孔入路全内镜下腰椎椎体间融合术（full endoscopic transforaminal lumbar interbody fusion）近年来在微创脊柱外科领域获得广泛应用,本文简要介绍该术式的发展历史、技术要点、适应证、疗效以及并发症。笔者认为经椎间孔入路全内镜下腰椎椎体间融合术具有与传统手术同样的临床效果,并且能够有效减少组织损伤和术中出血、降低术后腰背痛的发生率、缩短术后下床活动时间及平均住院日,但仍需完善远期随访,以进一步评估该术式的有效性和安全性。     

年轻女性乳腺癌外科治疗焦点问题及对策

年轻乳腺癌病人预后较差,与侵袭性生物学特征密切相关,是临床治疗的一大难点。年轻女性乳腺癌病人的外科手术抉择需要综合权衡肿瘤生物学特征、病人的自身需求、社会家庭支持因素等各个方面。对于早期肿瘤应当积极开展保乳手术,对于临床分期较晚的肿瘤,建议参照分子分型积极开展新辅助治疗,或者实施合适的乳房重建技术。临床医师应当为病人提供更加充分的信息与高级别的循证医学证据,鼓励病人积极参与外科手术决策的制定。     

LCBDE+LC与ERCP+LC治疗胆囊结石合并胆总管结石的网状Meta分析

目的 近年来,腹腔镜胆囊切除术（LC）、腹腔镜胆总管探查术（LCBDE）、内镜逆行胰胆管造影术（ERCP）普遍应用于胆系结石的治疗,本Meta分析比较了三种治疗胆囊结石合并胆管结石的手术方式的疗效及安全性,即LCBDE+LC、术前ERCP（PreERCP）+LC、术中ERCP（IntraERCP）+LC。方法 计算机检索Medline、PubMed、Cochrane Library、Embase数据库,查找1990—2019年关于LCBDE+LC、PreERCP+LC、IntraERCP+LC治疗胆囊结石合并胆总管结石的随机对照试验（RCT）研究。按照纳入与排除标准,选择文献、评价质量、提取数据,采用Stata软件进行网状Meta分析。计算累积排序概率曲线下面积（SUCRA）,用于预测各手术方式的有效性及安全性,主要结局指标为结石清除率,病死率,胰腺炎、胆漏、出血,以及中转开腹率。结果 共有19篇RCT研究纳入分析,共计2 627例患者。网状Meta分析结果显示：（1）结石清除率：IntraERCP+LC优于LCBDE+LC、PreERCP+LC,差异具有统计学意义（P＜0.05）;（2）病死率：LCBDE+LC、PreERCP+LC、IntraERCP+LC三者之间的差异均无统计学意义（P＞0.05）;（3）胰腺炎：PreERCP+LC的发生率高于LCBDE+LC、IntraERCP+LC,差异具有统计学意义（P＜0.05）;（4）出血：LCBDE+LC、PreERCP+LC、IntraERCP+LC三者之间的差异均无统计学意义（P＞0.05）;（5）胆漏：LCBDE+LC的发生率高于PreERCP+LC、IntraERCP+LC,差异具有统计学意义（P＜0.05）;（6）中转开腹率：PreERCP+LC与IntraERCP+LC、LCBDE+LC与IntraERCP+LC之间的差异均无统计学意义（P＞0.05）,而LCBDE+LC发生率高于PreERCP+LC,差异具有统计学意义（P＜0.05）。结论 LCBDE+LC、PreERCP+LC、IntraERCP+LC三种手术方式均可用于治疗胆囊结石合并胆总管结石,其中IntraERCP+LC的结石清除率最高,LCBDE+LC的胆漏风险较大,而PreERCP+LC的胰腺炎风险最高。     

基于一体化手术平台的LC联合术中ERCP治疗胆囊结石合并胆总管结石的效果研究

目的 探讨一体化手术平台中行腹腔镜胆囊切除术（LC）联合术中内镜逆行性胆胰管造影（ERCP）治疗胆囊结石合并胆总管结石的效果,并与序贯二步法ERCP+LC进行比较。方法 回顾性分析2019年12月至2020年12月由台州医院和恩泽医院肝胆胰外科完成治疗的82例胆囊结石合并胆总管结石患者临床资料,其中在一体化手术平台完成LC联合术中ERCP治疗的37例患者分为A组,完成序贯二步法ERCP+LC治疗的45例患者分为B组,比较两组手术时间、术中出血量、结石清除率、疼痛评分、排气时间、下床活动时间、术后并发症发生率、住院时间、住院费用等指标的差异。结果 两组术前基本资料比较无统计学差异,具有可比性（P>0.05）。两组在手术时间、术中出血量、结石清除率、术后疼痛评分、住院费用等方面无明显统计学差异（P>0.05）。A组术后排气时间[（16.0±4.5）h vs （19.9±6.0）h]、下床活动时间[（8.4±2.0）h vs （13.4±3.8）h]以及住院时间[（4.7±0.7）d vs （7.4±1.0）d]均明显短于B组（P<0.05）。两组患者在术后疼痛评分、住院费用方面无明显差异（P>0.05）。A组患者手术并发症总发生率[2.7%（1/37） vs 20.0%（9/45）]明显少于B组,差异有统计学意义（P<0.05）。结论 在一体化手术平台行LC联合术中ERCP治疗胆囊结石合并胆总管结石较序贯二步法ERCP+LC效果更好,能缩短住院时间,减少手术并发症,且不增加住院费用,是一种较好的治疗手段。     

Simultaneous bilateral hallux valgus surgery: Percutaneous or conventional? Early results of a matched study from a tertiary institution

BackgroundHallux valgus is bilateral in up to 84 % of cases. In the setting of simultaneous bilateral correction, we aim to evaluate if minimally invasive percutaneous surgery (MIS) provides any advantage compared to conventional open surgery.Methods52 feet (26 patients) undergoing simultaneous bilateral MIS surgery were matched by severity of deformity to 52 feet (26 patients) undergoing simultaneous conventional open surgery. Patients were followed for a minimum of six months. Pre- and post-operative radiographs and clinical records were reviewed.ResultsThere were no significant differences in pre-operative function or pain between both groups. Post-operatively, the mean hallux valgus angle (HVA) was significantly lower in the MIS group. (HVA MIS – 8.6; Open – 11.8, P = 0.013). There were no significant differences in post-operative outcome and patient satisfaction between both groups.ConclusionThis study demonstrates that simultaneous bilateral MIS hallux valgus surgery can be considered for patients with bilateral symptomatic hallux valgus.
