胆道手术缝合技术与缝合材料选择中国专家共识（2018版）

正胆道缝合重建是肝胆胰外科手术的最基本操作之一,建立胆汁引流通畅、无张力、血供充足的黏膜对黏膜吻合是胆道重建的基本要求。目前,胆道重建方式繁多,但根据所须重建胆道的病理生理状况选择合适的胆道缝合方法及缝合材料是保障胆道重建成功的关键因素。随着手术技术的进步及各种缝合材料的发展,胆道缝合技术越来越精细,高质量的胆道缝合重建是病人顺利康复及减少多次手术的关键。基于此,中华医学会外科学分会组织国内部分专家结合最新文献及胆道外科的最新进

Current practice and barriers of mesh-assisted implant-based breast reconstruction in China: A nationwide cross-sectional survey of 110 hospitals

BackgroundThe current National Practice Questionnaire of implant-based breast reconstruction (IBBR) (NPQi) was to assess the clinical practice of mesh-assisted IBBR in China.MethodsA questionnaire was mailed to 110 hospitals in China, which have more than 200 breast cancer operations performed in 2017. The survey mainly included questions on the type and timing of IBBR, questions about the use of TiLOOP® Bra and acellular dermal matrix (ADM) and the complications of IBBR.ResultsIBBR was routinely carried out in 86.36% (95/110) hospitals. IBBR was the most frequently-used (65.7%, 4,296/6,534) BR after mastectomy with a median of 24 cases (IQR 7.5–65) in each hospital. TiLOOP® Bra and ADM were available in 49.5% and 33.7% hospitals, respectively. Hospitals with ADM offered were more likely to located in economically developed regions (65.6%), when compared with hospitals without any mesh offered (14/35, 40.0%, P = 0.036) and with only TiLOOP® Bra offered (16/28, 57.1%, P = 0.032). The surgery volume was largely variated from hospitals without any mesh offered (median 380 cases, IQR 304–550), with only TiLOOP® Bra offered (median 790 cases, IQR 439–1096, P = 0.001) and with ADM offered (median 797 cases, IQR 497–1528, P < 0.001). Higher proportion of one-stage mesh-augmented direct-to-implant BR and lower proportion of autologous BR were observed in hospitals with mesh offered. The reported major complications were similar between hospitals with or without mesh offered.ConclusionsThe NPQi has provided a valuable insight into the current practice of IBBR and mesh used in China. The introduction of mesh-assisted techniques has revolutionized the clinical practice.     

“对位对线”补片固定法在腹腔镜切口疝修补术中的应用

背景与目的 切口疝的微创修补理念在疝外科界已经形成共识，腹腔镜下切口疝修补在临床上的应用越来越普及，但腔镜下的补片固定技术仍然是一个难点。本研究旨在介绍一种新式的切口疝补片固定方法并探讨其临床应用效果。方法 回顾性分析2018年1月—2019年12月中山大学附属第六医院胃肠、疝和腹壁外科120例行腹腔镜切口疝修补手术（IPOM）患者的临床资料，其中60例的补片固定方式采用“对位对线”补片固定法（观察组），另60例采用传统疝钉双圈固定方法（对照组），比较两组患者相关临床指标以及经济学指标。结果 两组患者性别、年龄、BMI、病程以及疝环最大缺损指标差异均无统计学意义（均P>0.05）。观察组的平均补片固定时间短于对照组（35.5 min vs. 47.7 min，P<0.05），平均疝钉固定数量少于对照组（36.6枚 vs. 44.2枚，P<0.05），平均术后疼痛VAS评分低于对照组（3.2分 vs. 4.6分，P<0.05），住院费用低于对照组（3.9万元 vs. 4.8万元，P<0.05）。两组患者在血清肿、补片感染发生率，术后住院时间的差异均无统计学意义（均P>0.05）。观察组和对照组平均随访26.3个月与25.8个月，观察组和对照组的切口疝复发率（1.7% vs. 5.0%，P=0.61）及术后慢性疼痛的发生率差异均无统计学意义（6.7% vs. 8.3%，P=1.00）。结论 “对位对线”补片固定法可缩短补片固定时间，减少疝钉使用数量，节约住院费用，并且可降低切口疝术后早期疼痛的发生，该方法在腹腔镜切口疝修补术中的应用是安全有效的，可在临床进行推广使用。     

Use of ventilation bag for the respiratory support during magnetic resonance imaging in Arnold-Chiari ventilated patients,a case report

Context: Magnetic Resonance Imaging (MRI) is an essential diagnostic tool for neuroimaging tissues such as the spinal cord. Unfortunately, the use of MRI may be limited in ventilated patients, who cannot maintain the supine position in spontaneous breathing for the whole duration of the exam (i.e. neuro-muscular patients with diaphragm involvement). The use of MRI-compatible ventilator during MRI could be a solution but they are not universally available. Furthermore, their performances are not up to those of the conventional ones and they are not always compatible with Non Invasive Ventilation (NIV).

Findings: This case report describes an easy and low-cost solution to ventilate a patient non-invasively during the MRI procedure. The patient in this case was a 45-yr-old man, wheelchair-dependent and chronically ventilated in NIV with a forced vital capacity in supine position of 370?ml (10% of predicted normal), affected by Arnold-Chiari Syndrome, and in need of a MRI diagnostic control.

Conclusion: The technique proposed, that does not affect the MRI images quality, consists in ventilating the patient using a simple nonmetallic Ventilation Bag, operated by a Respiratory Therapist. This has been proven a useful and economical solution for ventilatory support during MRI for a respiratory-dependent patient with Arnold-Chiari Syndrome.     

镍钛记忆合金皮内缝合对甲状腺手术切口愈合的影响

目的:探究甲状腺手术缝合时采用镍钛记忆合金皮内缝合对切口愈合的影响。方法:回顾性分析2018年1月-2019年1月125例在笔者医院行甲状腺手术患者相关资料,依据患者术后缝合方式分为合金皮内缝合组(n=60)与丝线间断缝合组(n=65),分别应用镍钛记忆合金皮内缝合与丝线间断缝合。比较两组患者术后恢复情况,切口愈合情况,切口瘢痕情况,切口美观优良率。结果:合金皮内缝合组患者术后疼痛持续时间、切口愈合时间以及住院时间均明显短于丝线间断缝合组患者,差异具有统计学意义(P<0.05);两组患者切口缝合时间比较差异没有统计学意义(P>0.05)。合金皮内缝合组患者切口愈合情况明显优于丝线间断缝合组,且切口瘢痕优良率明显高于丝线间断缝合组,差异具有统计学意义(P<0.05)。合金皮内缝合组与丝线间断缝合组切口美观优良率分别为95.00%与78.46%,差异有统计学意义(P<0.05)。结论:甲状腺手术切口缝合时应用镍钛记忆合金皮内缝合可以促进切口快速愈合,在保证切口美观优良率情况下促进患者快速康复,临床应用价值高。     

A comparison of double single suture-button fixation,suture-button fixation,and screw fixation for ankle syndesmosis injury: A retrospective cohort study

Different methods have been used throughout the years for syndesmotic injury but there is no consensus on the ideal treatment. Some methods are expensive and some have more complications. The aim of this study is to compare single suture endobutton with double suture endobutton and screw fixation for syndesmotic injury.Sixty nine patients with syndesmotic injury with fibular fractures whom were treated with a single interosseous suture endobutton system (ZipTight^TM, Zimmer Biomet), a double interosseous suture endobutton system (ZipTight^TM, Zimmer Biomet) and 1 syndesmotic screw (TST, Istanbul, Turkey) were included in this study. Functional and radiological results from patient records between 2015 and 2018 were retrospectively evaluated.Twenty patients were treated with the double interosseous suture endobutton, 23 were treated with the single interosseous suture endobutton, and 26 were treated with traditional AO screw fixation. Three patients from the screw fixation group (11.5%) required revision surgery (P < .05). All the radiologic and clinical outcomes were statistical similar in all 3 groups.Our findings showed that the interosseous suture endobutton system is at least as safe as the screw fixation technique for treatment of syndesmosis joint injuries and can be used as an alternative to the screw method. The interosseous suture endobutton system eliminates the need for a second surgery to remove the hardware, which minimizes the probability of re-diastasis. Since our results showed no statistical difference between single and double interosseous suture endobutton systems, the less costly single endobutton system may be the better alternative.
