腹腔镜手术具有手术创伤小、术后恢复快、能直视下放大和清晰观察组织结构等优点,正在全世界范围内广泛开展,已成为目前手术发展的主要趋势。1997年Schuessler 等[1]首次报道9例腹腔镜下前列腺癌根治术( LRP)。随着手术器械的完善并经Guil-lonneau等[2,3]标准化手术过程以后,手术效果与开放手术相比已无明显差异。2000年Abbou等[4]首次报道了机器人辅助下的前列腺癌根治术( RALP ),揭开了前列腺癌治疗的新篇章,而后美国Vattikuti研究所将其进一步完善。目前上万例的RALP手术结果表明,其较常规腔镜手术表现出明显优势,已成为欧美国家前列腺癌手术治疗的主要方法。国内于2006年开始逐渐引进da Vinci 机器人系统。2008年Kaouk等[5]首次报道了单孔LRP ( LESS ),目前我国也有少数学者报道该种术式,整个操作过程空间更小、操作难度增加,但目前并未见其较常规腔镜手术有特殊优势,仍在进一步发展中。短短十几年,LRP治疗技术取得了飞速地提升。现就LRP的应用进展情况综述如下。 相似文献

目的 探讨前列腺癌根治术后切缘阳性与相关临床参数的关系.方法 回顾性分析118例行前列腺癌根治术的前列腺癌患者的临床资料,分析术前血清PSA、临床分期、体重指数(BMI)、前列腺体积及术后Gleason评分与术后切缘阳性的相关性.结果 不同BMI、前列腺体积及血清PSA水平,切缘阳性与切缘阴性差异无统计学意义(P>0.05),而切缘阳性与切缘阴性在不同临床分期及Gleason评分中差异显著(P<0.05).临床分期和Gleason评分与术后切缘阳性均呈现正相关(r=0.94和0.83,均P<0.05).结论 Gleason评分和病理分期与术后切缘阳性呈正相关,Gleason评分越高,临床分期越晚,术后切缘阳性的发生率也就越大. 相似文献

目的探讨老年前列腺癌经腹膜外腹腔镜根治术围手术期的护理要点与方法。方法对5例老年前列腺癌患者经腹膜外腹腔镜根治术围手术期护理过程进行总结分析。结果由于术前重视心理护理,指导适应术后的功能锻炼,加强饮食调节和切实做好肠道的充分准备,故手术过程顺利,出血少;术后注意加强生命体征的监测,保持各引流管的通畅,恢复快,减少了并发症的发生。5例均获手术成功,随访2~24个月,未见局部复发或生化复发。结论加强围手术期的整体护理是老年前列腺癌经腹膜外腹腔镜根治术手术成功和完全康复的重要保证。 相似文献

前列腺癌根治术已有一百多年的历史,由于严重的手术并发症限制其临床应用。20世纪的80年代初,Walsh等提出解剖性前列腺癌根治术的概念,使人们了解盆腔的解剖结构,手术并发症因而大幅度下降。前列腺根治性切除已经是公认的早期前列腺癌最佳治疗方法。解剖性耻骨后前列腺癌根治术可以完整切除肿瘤,保留血管神经索,减少术后勃起功能障碍(ED)的发生率以及有效保护尿道外括约肌,90%以上的患者能保留控尿功能。 相似文献

Esophageal diverticula are rare conditions that cause esophageal symptoms, such as dysphagia, regurgitation, and chest pain. They are classified according to their location and characteristic pathophysiology into three types: epiphrenic diverticulum, Zenker's diverticulum, and Rokitansky diverticulum. The former two disorders take the form of protrusions, and symptomatic cases require interventional treatment. However, the esophageal anatomy presents distinct challenges to surgical resection of the diverticulum, particularly when it is located closer to the oral orifice. Since the condition itself is not malignant,minimally invasive endoscopic approaches have been developed with a focus on alleviation of symptoms. Several types of endoscopic devices and techniques are currently employed, including peroral endoscopic myotomy(POEM). However,the use of minimally invasive endoscopic approaches, like POEM, has allowed the development of new disorder called iatrogenic esophageal diverticula. In this paper, we review the pathophysiology of each type of diverticulum and the current state-of-the-art treatment based on our experience. 相似文献

As one of the earliest surgeries applying knotless barbed suture, the minimally invasive radical prostatectomy (MIRP) was reported to have various effects on the patients and the surgeons. This study reviewed the available evidence about the efficacy and safety of barbed sutures in MIRP. We searched ClinicalTrials.gov, Cochrane Register of Clinical Studies, PubMed, and Embase to identify randomized controlled trials (RCTs) and cohort studies addressing the application of barbed sutures and conventional sutures in MIRP (until August 2016). Quality assessment was performed according to Cochrane recommendations. The data were analyzed using Review Manager (Version 5.3), and sensitivity analysis was performed by sequentially omitting each study. A total of 12 studies, including three RCTs (low to moderate risk of bias, 211 patients) and nine cohort studies (low to moderate risk of bias, 698 patients), fulfilled the study criteria. The pooling of trials did not show statistical difference. Pooling data of cohort studies showed that suture time [mean difference (MD) = ?8.52, 95% confidence interval (CI) = ?12.60 to ?4.43, p < 0.0001] and length of hospital stay (MD = ?0.96, 95% CI = ?1.80 to ?0.11, p = 0.03) were significantly shorter in the barbed group. Results of continence rate varied according to different studies. Subgroup analysis by type of MIRP suggested that patients who underwent barbed suture during robot-assisted surgeries had a shorter hospital stay (MD = ?1.13, 95% CI = ?1.82 to ?0.45, p = 0.001). During the laparoscopic surgery, patients in the barbed suture group had fewer postoperative complications [odds ratio = 0.29, 95% CI = 0.08–0.98, p = 0.05). However, more evidence is needed to validate this state-of-the-art technology. 相似文献

Surgery represents today the standard treatment of oesophageal and gastric cancer. Associated morbidity remain however significant in term of incisional access and functional sequels after organ resection and extended lymphadenectomy. Retrospective reviews of surgical series have defined indications for which more conservative treatment appears to provide similar survival without the need for lymph node resection. Endoscopic resection is now accepted for the treatment of well-differentiated tumors restricted to the mucosa. The expansion of this technique to deeper lesions or to lesions developed on a background of metaplasia is associated with an increased morbidity and significant risk of recurrence as well as a lifelong, close endoscopic surveillance. The role of surgery as primary treatment or rescue therapy to extend the resection will rely on an accurate preoperative and pathological staging of the lesion. Laparoscopy can play a central role in the management of early oesophageal and gastric cancer as it can permit from localized to extensive resection associated to lymph node dissection with the advantage of minimal invasive surgery. Its association to function-preserving operations awaits the demonstrated efficacy of targeted lymph node dissection. Those new techniques should be restricted to centres with extensive expertise and need to be validated in long-term controlled studies. 相似文献

In recent years prostate cancer has become the predominant malignancy in men. With the introduction of prostate specific antigen (PSA) the disease can be diagnosed at an early stage, at which surgical therapy can be curative. In the past century, the retropubic and the perineal routes were established as alternatives of surgical access to the gland for clinically localized prostate cancer. The selection of the operative route is mostly decided individually on the basis of surgical training and experience. The revived interest in perineal radical prostatectomy is explained by the fact that this technique has been associated with low morbidity. The differences of both surgical approaches of radical prostatectomy are elucidated and compared regarding tumor control and short and long term complication rates. Taking these results into consideration, specific advantages and disadvantages of radical perineal prostatectomy are emphasized. 相似文献

New approaches to the minimally invasive treatment of lung cancer 总被引:15,自引:0,他引:15
PURPOSE OF REVIEW: The momentum for minimally invasive thoracic surgery has been growing. Thousands of video-assisted thoracoscopic surgery lobectomies have been performed since the first video-assisted thoracoscopic surgery lobectomy was performed in 1992, but currently most lobectomies are still performed via a thoracotomy. Although most lobectomies could be performed with video-assisted thoracoscopic surgery, less than 5% are currently performed that way. Compared with a thoracotomy, video-assisted thoracoscopic surgery offers patients a shorter length of stay, less pain, and a quicker recovery, without compromising the adequacy of the operation. The purpose of this review is to identify the current uses for minimally invasive procedures in thoracic surgery and to present the current data regarding these procedures. RECENT FINDINGS: Complete anatomic resections and node dissections are routinely being performed at several centers internationally. The median length of stay after video-assisted thoracoscopic surgery lobectomy is 3 days, and 84.7% of patients had no complications. Studies comparing video-assisted thoracoscopic surgery and thoracotomy suggest that minimally invasive surgery causes less pain, has a smaller impact on postoperative pulmonary function, and provides a quicker return to regular activity, with at least comparable survival for cancer patients. SUMMARY: Current data suggest that, compared with a thoracotomy, video-assisted thoracoscopic surgery has advantages for anatomic pulmonary resections. 相似文献
