| 1 | Extraperitoneal robot-assisted radical prostatectomy: Comparison with transperitoneal technique显示文摘AIM: To determine peri-operative, oncological, functional and safety profiles of extraperitoneal robot-assisted radical prostatectomy(e RARP) vs transperitoneal robot-assisted radical prostatectomy(t RARP) in a single centre.METHODS: A total of 120 consecutive patients underwent 50 e RARP and 70 e RARP operations respectively by the same surgical team. Peri-operative and post-operative outcomes including blood loss, hospitalization, complications(Clavien grade), positive surgical margin(PSM) rates, continence and erectile function were compared. The performance of e RARP required several technical modifications. These included developmentof Retzius' space by balloon insufflation, laparoscopic dissection of lateral extensions of this area; caudal port positioning; cranial digital stripping of peritoneum for sucker port and lodging the bagged prostate specimen adjacent to the lateral assistant port to permit space for urethro-vesical anastomosis.RESULTS: Robotic console times were shorter with e RARP vs t RARP(145.1 min vs 198.3 min, P < 0.0001). There were no significant differences in blood loss, PSM rates(e RARP 17.7% vs t RARP 22%) or complications(e RARP 8.5% vs t RARP 8%). A drain was used in all patients after t RARP and in 25/70 e RARP cases. Length of hospital stay was shorter after e RARP(mean 1.94 d vs 3.6 d, P < 0.0002). There were no differences between techniques in continence or potency at 6 mo. e RARP required several technical modifications: development of Retzius' space by balloon insufflation, laparoscopic dissection of lateral extensions of this area; caudal port positioning; and lodging the bagged prostate specimen adjacent to the lateral assistant port to permit space for urethro-vesical anastomosis.CONCLUSION: e RARP demonstrated advantages in surgical times, hospital stay and equivalence in PSM rates, complications and functional outcomes. e RARP is a useful alternative to t RARP especially in patients with adhesions, pre-existing inguinal hernias, or those unable to withstand steep Trendelenburg position. | Chris Anderson Ben Ayres Rami Issa Matthew Perry Evangelos Liatsikos Jens-Uwe Stolzenburg Khurshid R Ghani | 2013 | World Journal of Clinical Urology2013，2，2： | 1 |
| 2 | 单管球囊腔内治疗和组织间插植治疗早期乳腺癌的剂量和临床比较显示文摘目的比较单管球囊腔内治疗(MammoSite)和组织间插植两种高剂量率(HDR)后装技术行早期乳腺癌保乳术后局部乳腺加速照射的剂量学优缺点、早晚期毒副作用及美容评估。方法自2004年1月至12月,10例乳腺癌在肿瘤局部扩大切除后使用了高剂量率^192Ir加速照射(APBI),其中组织间插植6例、MammoSite4例。全部息者均在手术中植入施源器,组织间插植组瘤腔距皮肤〉0.5~0.7cm,MammoSite中1例瘤腔距皮肤0.65cm,其余3例均大于1cm。治疗靶区组织间插植组为瘤腔外2cm(皮肤和胸壁方向根据实际情况略小),MammoSite组为球囊外1cm。组织间插植组中位剂量均匀指数(DHI)为0.77,MammoSite组中位DHI为0.73。结果全部患者随诊12~24个月,中位随诊18个月,随诊率为100%。治疗期间两组无一例发生Ⅲ级以上急性反应,仅发生红斑、水肿、乳腺触痛和感染,均为1~2级。晚期毒性(皮肤纤维化、乳腺触痛、脂肪坏死)组织间插植组较MammoSite组略高。美容效果达到极好和良好的在治疗结束时为100%,随诊12个月时组织间插植组患者和医生评估分别是100%和83%,MammoSite组均为100%。无一例局部复发。结论组织间插植剂量分布较MammoSite均匀而且治疗体积大;MammoSite重复性好、操作简单,早晚期毒副作用及美容效果相同。 | 修霞 Ray Lin Colin Chu Chris Issa Prabhakar Tripuraneni | 2007 | 中华放射医学与防护杂志2007，27，2： | 1 |
