关节镜下肩袖缝线过线器捆扎缝合半月板撕裂伤疗效观察

目的:探讨采用肩袖缝线过线器进行关节镜下半月板撕裂捆扎缝合的临床疗效。方法:自2015年7月至2019年5月采用关节镜下肩袖缝线器捆扎缝合半月板撕裂损伤患者40例,其中男27例,女13例;年龄20～55(36.0±1.4)岁。观察术后并发症情况,术前及术后12个月采用Lysholm膝关节评分标准评价临床疗效,采用疼痛视觉模拟评分(visual analogue scale,VAS),膝关节屈伸活动范围评估疼痛与功能恢复情况。结果:所有患者获得随访,时间12～15(12.6±0.7)个月。未出现关节积液、缝合失效等并发症。2例患者末次随访时膝关节存在轻度疼痛,但临床查体无异常;1例患者中度疼痛合并关节间隙局部按压痛,其余患者均无异常。Lysholm膝关节评分由术前的(49.55±1.21)分提高到术后12个月的(98.95±0.42)分,VAS评分由术前的(5.18±0.78)分降至术后12个月的(1.03±0.77)分,膝关节屈伸活动范围由术前的(50.63±9.20)°提高到术后12个月的(130.38±4.99)°,差异有统计学意义(P0.05)。结论:关节镜下使用肩袖缝线过线器捆扎缝合适用于大部分的半月板损伤,包括内侧半月板后角撕裂,及外侧半月板体部、后角撕裂。此项技术解决了缺乏专用半月板缝合器情况下的半月板全内缝合需求,且具有手术操作方便,并发症少,术后功能好等优点。

Pictorial Review of Craniosynostosis

Craniosynostosis refers to the premature closure of calvarial sutures. Premature closure is subclassified into primary and secondary causes. The clinical manifestations of premature closure depend upon the involved suture and the resultant cranial dysmorphism. Common clinical disabilities include mental retardation, visual deficits, and oropharyngeal airway obstruction. Treatment is based on patient age and clinical severity. This article reviews the imaging manifestation of the most common forms of craniosynostosis with an emphasis on plain film and CT appearance of the disease. We also briefly review the appearance of common mimickers of suture pathology.

Suture Versus Tack Fixation of Mesh in Laparoscopic Umbilical Hernia Repair

Background and Objectives:

Mesh fixation in laparoscopic umbilical hernia repair is poorly studied. We compared postoperative outcomes of laparoscopic umbilical hernia repair in suture versus tack mesh fixation.

Methods:

Patients who underwent laparoscopic umbilical hernia repair were separated by method of mesh fixation: sutures versus primarily tacks. Medical history and follow-up data were collected through medical records. The primary outcome of this study was the recurrence rates of hernias. Postoperative major and minor complications, such as surgical site infection, small-bowel obstruction, and seroma formation, were regarded as secondary outcomes. Additionally, a telephone interview was conducted to assess postoperative pain, recovery time, and overall patient satisfaction.

Results:

Eighty-six patients were identified: 33 in the suture group and 53 in the tacks group. The number of emergent cases was increased in the tacks group (6 vs 0; P = .022). Mean follow-up time was 2.7 years for both groups. Documented postoperative follow-up was obtained in 29 (90%) suture group and 31 (58%) tacks group patients. Hernia recurrence occurred in 3 and 2 patients in the sutures and tacks groups, respectively (P was not significant). No differences were found in secondary outcomes, including subjective outcomes from telephone interviews, between groups.

Conclusions:

There are no differences in postoperative complication rates in suture versus tack mesh fixation in laparoscopic umbilical hernia repair.     

两种可吸收缝合线在鼻内镜手术中的应用

目的　比较人工合成可吸收线与胶原蛋白可吸收线对鼻内镜手术切口愈合时间和拆线时疼痛情况。方法  100例鼻内镜手术随机分为A、B两组,每组50例。A组：采用胶原蛋白可吸收线;B组：采用人工合成可吸收线,比较两组切口愈合时间和拆线时疼痛情况。结果　A、B两组切口愈合无明显差异（P >0.05）,但二组在脱略时间、拆线时疼痛有明 显差异（P <0.05）。结论　胶原蛋白可吸收线降解脱略时间与鼻内镜手术伤口愈合时间较匹配,是较为理想的选择。     

可吸收缝线材料的可降解与临床应用

背景：由于可吸收缝合线具有良好的生物相容性及机械强度,在临床被广泛应用。 目的：探讨不同可吸收性缝线的体外降解性能,分析可吸收缝合线临床应用中的优势及其体外降解行为的影响因素。 方法：通过检索近年来文章内容与可吸收缝线材料降解性能和应用相关的文献,从可吸收缝线材料的性能及降解行为影响因素、可吸收与不可吸收缝合线临床应用比较等对可吸收缝线材料相关研究成果作回顾性分析,为临床提供理论依据。 结果与结论：可吸收缝合线体可被机体完全降解吸收,无不良反应,创口愈合后不留瘢痕,克服了不可吸收缝合线不能在体内分解的缺点,其降解产物的体内吸收主要有2个途径：一为体内巨细胞与吞噬细胞吞噬,另一途径为降解产物进入人的体液与血液,如乳酸通过体循环被吸收排泄。人体内有一个极其复杂的生理环境,存在着影响材料性能的各种因素。加之材料的种类不同,它们在体内的降解行为也不尽相同,因此需要在一定范围内设计合成和加工出具有特殊性能的可降解高分子材料满足临床需要。中国组织工程研究杂志出版内容重点：生物材料;骨生物材料; 口腔生物材料; 纳米材料; 缓释材料; 材料相容性;组织工程全文链接：     

Intraoperative technique as a factor in the prevention of surgical site infection

Approximately five percent of patients who undergo surgery develop surgical site infections (SSIs) which are associated with an extra seven days as an inpatient and with increased postoperative mortality. The competence and technique of the surgeon is considered important in preventing SSI. We have reviewed the evidence on different aspects of surgical technique and its role in preventing SSI. The most recent guidelines from the National Institute for Health and Clinical Excellence in the UK recommend avoiding diathermy for skin incision even though this reduces incision time and blood loss, both associated with lower infection rates. Studies comparing different closure techniques, i.e. continuous versus interrupted sutures, have not found a statistically significant difference in the SSI rate, but using continuous sutures is quicker. For contaminated wounds, the surgical site should be left open for four days to allow for treatment of local infection before subsequent healing by primary intention. Surgical drains should be placed through separate incisions, closed suction drains are preferable to open drains, and all drains should be removed as soon as possible. There are relatively few large studies on the impact of surgical techniques on SSI rates. Larger multicentre prospective studies are required to define what aspects of surgical technique impact on SSI, to better inform surgical practice and support education programmes for surgical trainees.
