Clinical evaluation of a novel commercial single port in laparoendoscopic single-site surgery

IntroductionEndoscopic total extraperitoneal herniorrhaphy (TEP) has emerged as a recognized surgical method for adult inguinal hernia. To reduce port-site-related morbidity and improve postoperative convalescence, a novel surgical approach known as laparoendoscopic single-site surgery (LESS) TEP repair has been developed.AimTo compare the clinical efficiency of a novel commercial single port with a homemade single port in TEP groin hernia repair.MethodsSixty consecutive patients undergoing LESS TEP repair were enrolled in this trial with 31 in the homemade port group and 29 in the commercial single-port group. Preoperative, intraoperative, and postoperative factors were recorded. The patients were interviewed postoperatively at outpatient clinics.ResultsThe demographic data were comparable between the two groups. The median operative time was longer in the homemade port group than in the commercial port group (59.4 vs. 51.4 minutes, respectively, p = 0.04). The homemade port group was significantly associated with more port-related malfunctions than the commercial port group (19% vs. 0, respectively, p = 0.02). The postoperative results were comparable between the groups in pain scores, analgesic requirements, complications, and postoperative convalescence.ConclusionThe novel commercial single port studied is associated with less intraoperative malfunctions and improved the procedural efficiency of LESS TEP for groin hernia repair. Thus, a well-designed commercial port will be of significant benefit in overcoming the existing procedural inefficiencies of single-port surgery performed using a homemade port, which requires relatively time-consuming procedures and significant experience of the surgeon.     

肠造口的规范化实施及造口旁疝的预防策略

肠造口在肠道良恶性疾病治疗和创伤救治中发挥重要作用,其规范化实施是减少造口并发症、提高造口病人生活质量的关键。外科医师首先要建立肠造口是肠道与皮肤吻合口的概念,术前应由外科医师、造口治疗师、病人及家属共同选择造口部位。应采取个体化危险因素评估以决定是否行预防性造口。规范化操作包括：合理选择造口部位、腹部切口大小、腹壁通道宽度以及造口外置高度,良好缝合造口肠管与腹壁各层组织等。造口旁疝是最常见的造口远期并发症。女性、肥胖、糖尿病等是造口旁疝常见的危险因素,多项研究结果表明,腹膜外造口和预防性补片置入能降低造口旁疝发生率。     

腹膜外途径腹腔镜下根治性前列腺切除术切缘阳性的影响因素

目的探讨经腹膜外途径腹腔镜下根治性前列腺切除术后切缘阳性的影响因素。方法回顾性分析我院2010年1月至2018年12月99例行腹膜外途径腹腔镜下根治性前列腺切除术患者的临床资料。年龄51~79岁,平均(65.37±6.07)岁;前列腺特异抗原(PSA)2.80~79.50ng/mL,平均(16.84±12.28)ng/mL。分析术后病理切缘阳性的特征。按年龄、体质指数、术前PSA水平、穿刺针数阳性百分率、穿刺至手术时间、穿刺病理Gleason评分、临床T分期、前列腺癌危险分度、术后病理Gleason评分、术后T分期、腹盆腔手术史等进行分组,分析各组切缘阳性率的差异。采用χ^2检验进行单因素分析,有统计学差异的变量进入多因素Logistic回归分析,评价临床及病理相关资料与切缘阳性的关系。结果本组99例患者均在腹腔镜下顺利完成,无1例中转开放,手术时间平均(199.66±66.01)min,术中出血量平均(152.02±140.28)mL。术后病理证实均为前列腺癌,术后病理切缘阳性26例(26.3%)。将各危险因素分组后进行单因素分析,结果显示不同穿刺针数阳性百分率(P=0.047)、穿刺病理Gleason评分(P=0.023)、术后病理Gleason评分(P=0.007)、术后T分期(P=0.004)与切缘阳性存在相关性(P<0.05),而年龄(P=0.134)、体质指数(P=0.838)、术前PSA水平(P=0.299)、穿刺至手术时间(P=1.000)、临床T分期(P=0.821)、前列腺癌危险分度(P=0.903)、腹盆腔手术史(P=0.607)与切缘阳性均无相关性(P>0.05)。将单因素分析差异有统计学意义的指标及术前PSA、临床分期进行多因素分析,结果显示仅术后T分期(P=0.011)是切缘阳性的独立危险因素。结论穿刺针数阳性百分率、穿刺病理Gleason评分、术后病理Gleason评分、术后T分期与切缘阳性存在相关性,其中穿刺针数阳性百分率、穿刺病理Gleason评分及术后T分期越高,切缘阳性率越高。术后T分期是经腹膜外途径腹腔镜下根治性前列腺切除术后切缘阳性的独立危险因素。     

头侧入路的内镜下全腹膜外疝修补术治疗原发性腹壁疝的临床研究

目的探讨治疗原发性腹壁疝的微创新方法——头侧入路的内镜下全腹膜外疝修补术（TEA）的临床效果。 方法回顾性分析2019年11月至2020年1月,南方医科大学附属何贤纪念医院患者2例,河南中医药大学第一附属医院患者1例,河南省商丘市睢县中医院患者2例,郑州市第七人民医院患者1例,共6例接受头侧入路的TEA手术的原发性脐疝患者的临床资料。阐述手术操作流程及技术细节,分析其可行性和有效性。 结果6例患者术中均成功分离中上腹腹膜外空间并置入大张网片加强修复脐疝缺损,手术均获得成功,无中转开放手术。平均手术时间164 min（120～240 min）。术后伤口疼痛较轻,且术后第1天平均疼痛视觉模拟评分2.2分（2～3分）。术后平均住院时间2.2 d（2～3 d）。术后1例出现脐部少量血清肿,观察后自愈,未影响手术效果。术后随访时间6～15周,未发现复发患者。 结论头侧入路的TEA术式是安全可行的,可作为治疗中线原发性腹壁疝的一个选择,同时也是对TEA术式的一个补充。此术式扩大了TEA技术的适应证,避免了腹腔内置片修补术的弊端,值得向经验丰富的腔镜疝外科医师有限度推广。     

Conversion to Stoppa Procedure in Laparoscopic Totally Extraperitoneal Inguinal Hernia Repair

Background and Objectives:

Conversion to open surgery is an important problem, especially during the learning curve of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair.

Methods:

Here, we discuss conversion to the Stoppa procedure during laparoscopic TEP inguinal hernia repair. Outcomes of patients who underwent conversion to an open approach during laparoscopic TEP inguinal hernia repair between September 2004 and May 2010 were evaluated.

Results:

In total, 259 consecutive patients with 281 inguinal hernias underwent laparoscopic TEP inguinal hernia repair. Thirty-one hernia repairs (11%) were converted to open conventional surgical procedures. Twenty-eight of 31 laparoscopic TEP hernia repairs were converted to modified Stoppa procedures, because of technical difficulties. Three of these patients underwent Lichtenstein hernia repairs, because they had undergone previous surgeries.

Conclusion:

Stoppa is an easy and successful procedure used to solve problems during TEP hernia repair. The Lichtenstein procedure may be a suitable option in patients who have undergone previous operations, such as a radical prostatectomy.     

TAPP与TEP治疗腹股沟疝的临床对比研究

目的探讨TAPP与TEP治疗腹股沟疝的临床治疗效果。方法选取2015年1月-2017年12月至本院行腹腔镜疝修补手术的单侧腹股沟疝患者134例为观察对象,按手术方式的不同随机分为TEP组及TAPP组两组。对比分析两组的手术时间、手术出血量、住院时间、住院费用、术后24 h急性疼痛评分(VSA)、并发症发生率。结果 TEP组手术时间、住院费用明显短于或少于TAPP组,差异具有统计学意义。术后24 h急性疼痛评分(VSA)两组相比差异无统计学意义。TEP与TAPP在手术出血量、住院时间、并发症发生率方面差异无统计学意义。结论 TAPP并不增加术后早期急性疼痛的发生率,TAPP与TEP均是治疗腹股沟疝的有效方式。     

腹腔镜手术治疗造口旁疝的共识与争议

造口旁疝治疗较为复杂，总体疗效不如腹壁切口疝。腹腔镜手术治疗造口旁疝有较多的获益，但目前难以形成适用于所有病人和所有医师的临床解决方案。早期Keyhole手术开展较多，近年来Sugarbaker手术开展比例增高。现有“弱证据”指向的初步共识是Sugarbaker优于Keyhole，但在修补材料有待改进的情况下，Sugarbaker替代Keyhole尚为时过早，二者均有各自的临床适应证。腹腔镜修补结合造口原位重建技术在恢复造口功能等方面取得了非常好的效果。对于无明显重建指征的造口旁疝，也可在全腹腔镜下游离肠管、关闭缺损、缩小疝囊，既可将感染、造口相关并发症等风险降至最低，又可获得满意的疗效。近年来，各类腔镜腹膜外修补技术（EER）逐渐兴起，在造口旁疝领域，EER目前处于探索阶段，适应证有限。由于高质量、多中心、大样本RCT的匮乏，临床决策推荐尚缺乏高级别的证据支持，腹腔镜造口旁疝修补手术的术式选择争议还将持续。随着更多高质量文献的发表，相信外科医师一定能够在共识中解决争议，在争议后达成共识，为造口旁疝病人提供最佳的微创治疗策略。     

Midline extraperitoneal approach for bilateral widespread retroperitoneal abscess originating from anorectal infection

IntroductionAnorectal abscess is one of the most common anorectal conditions encountered in practice. However, such abscesses may rarely extend upward and cause life-threatening medical conditions.Presentation of caseA 53-year-old woman presented with symptoms of anorectal abscess and evidence of severe inflammatory response and acute kidney injury. Computed tomography revealed a widespread abscess extending to the bilateral retroperitoneal spaces. Surgical drainage was performed via a totally extraperitoneal approach through a lower midline abdominal incision, and the patient had a rapid and uncomplicated recovery.DiscussionAlthough retroperitoneal abscesses originating from the anorectal region are rare, they are life-threating events that require immediate treatment. Percutaneous abscess drainage has been recently evolved; however, surgical drainage is required sometimes that may be challenging, particularly in the case of widespread abscesses, as in our case.ConclusionThe midline extraperitoneal approach reported here might be an effective surgical option for patients with bilateral widespread retroperitoneal abscesses.
