Objective: To evaluate the efficacy and safety of self-retaining barbed suture in renorrhaphy during laparoscopic partial nephrectomy by comparing surgical outcomes in a prospective randomized manner.Material and methods: From July 2014 to July 2015, a total of 60 patients with T1 renal tumor were randomized into two equal groups: self-retaining barbed suture (SRBS) and conventional absorbable polyglactin suture (non-SRBS group). All patients were treated by retroperitoneal laparoscopic partial nephrectomy. One surgeon with high volume experience performed all procedures. The patient demographics and perioperative outcomes were compared.Results: The patient demographics and tumor characteristics were comparable. The mean tumor size and R.E.N.A.L. scores were comparable between the two groups. LPN was successfully accomplished in all patients without open conversion. The warm ischemia and renorrhaphy times were significantly shorter in the SRBS group (18.8?±?8.2 vs. 22.9?±?7.3?min, P?=?.04; 10.4?±?3.7 vs. 13.8?±?5.6?min, P?=?.01). The minor complication rate was 13.3% vs. 10.0%, which was comparable. No major complication occurred.Conclusions: The randomized controlled trial demonstrates that SRBS for renorrhaphy during retroperitoneal laparoscopic partial nephrectomy is safe and efficient. Application of barbed suture simplifies the parenchymal repair procedure and reduces warm ischemia time in comparison with conventional suture. 相似文献

Fishing is a worldwide pastime enjoyed by millions of people. Ocular fishing injuries though uncommon may cause potentially devastating ocular trauma. We report a rare case of penetrating injury of the cornea by a barbed fish hook and its successful surgical management by “cut-it out technique”. We are discussing the various techniques available for removal of fish hooks. The hook can be successfully removed with minimal trauma to ocular structures by understanding the structure of the fish hook and by employing the appropriate method of extraction. 相似文献

The purpose of this study was to compare barbed sutures to traditional sutures in three domains: time, cost, and wound related outcomes in total knee arthroplasty (TKA) and total hip arthroplasty (THA). A total of 34 patients were enrolled in a prospective randomized controlled trial to assess time to wound closure and cost. In addition, a retrospective chart review of an additional 100 patients was conducted to further assess wound-related outcomes. On average, barbed sutures decreased time to wound closure by 9.72 min (P < 0.05) after controlling for length of incision, patient's BMI and number of physicians closing. Further, using barbed sutures saved an average of $549.59 per case. However, increased frequency and severity of wound complications were associated with barbed sutures. 相似文献

Background
This study aimed to compare the biomechanical strength and permeability of barbed vs traditional suture for closure of the porcine knee joint.Methods
This study used Duroc pig knee joints. For each specimen, a 5-cm medial parapatellar arthrotomy was performed with the knee at 30° of flexion. We closed the arthrotomy wound using barbed suture (size 1/0 V-Loc 180) or traditional suture (size 1/0 PDS II). Specimens were divided into a PDS II (n = 9) and a V-Loc group (n = 9) for biomechanical testing, and a PDS II (n = 9) and a V-Loc group (n = 9) for permeability testing. In biomechanical testing, a continuous load was applied and the wound was pulled apart at 50 mm/min. We compared the maximum load under which each suture type could maintain wound closure. In permeability testing, the knee joints were flexed and extended for 200 cycles at 0.5 Hz from 0° to 120° of flexion. A tube was fixed in the articular cavity of the specimen and connected to a 1.5-m high water capsule. The time taken to wound effusion was compared.Results
There was no significant difference between the mean load at initial failure for PDS II (424 ± 192 N) vs V-Loc (471 ± 100 N, P = .529), or between the mean time until effusion for PDS II (6.8 ± 3.4 seconds) vs V-Loc (5.5 ± 2.5 seconds, P = .390).Conclusion
Standard and barbed suture had similar wound holding strength and permeability. The barbed suture was as stable as traditional suture. 相似文献6.

Rac small GTPases may play an important regulatory role in osteoclastogenesis. Our in vitro and in vivo results show that both Rac1 and Rac2 are required for optimal osteoclast differentiation, but Rac1 is more critical. Rac1 is the key Rac isoform responsible for regulating ROS generation and the actin cytoskeleton during the multiple stages of osteoclast differentiation. Introduction: Recent evidence suggests that the Rac small GTPases may play an important regulatory role in osteoclastogenesis. This finding is important because bisphosphonates may regulate their antiresorptive/antiosteoclast effects through the modification of Rho family of small GTPases. Materials and Methods: To elucidate the specific roles of the Rac1 and Rac2 isoforms during osteoclastogenesis, we used mice deficient in Rac1, Rac2, or both Rac1 and Rac2 in monocyte/osteoclast precursors. Macrophage‐colony stimulating factor (M‐CSF)– and RANKL‐mediated osteoclastogenesis in vitro was studied by using bone marrow‐derived mononucleated preosteoclast precursors (MOPs). The expression of osteoclast‐specific markers was examined using quantitative real‐time PCR and Western blot analysis. Free actin barbed ends in bone marrow MOPs after M‐CSF stimulation was determined. The ability of MOPs to migrate toward M‐CSF was assayed using Boyden chambers. Margin spreading on heparin sulfate‐coated glass and RANKL‐induced reactive oxygen species generation were also performed. Functional assays of in vitro‐generated osteoclasts were ascertained using dentine sections from narwal tusks. Osteoclast levels in vivo were counted in TRACP and immunohistochemically stained distal tibial sections. In vivo microarchitexture of lumbar vertebrate was examined using μCT 3D imaging and analysis. Results: We show here that, although both Rac isoforms are required for normal osteoclast differentiation, Rac1 deletion results in a more profound reduction in osteoclast formation in vitro because of its regulatory role in pre‐osteoclast M‐CSF‐mediated chemotaxis and actin assembly and RANKL‐mediated reactive oxygen species generation. This Rac1 cellular defect also manifests at the tissue level with increased trabecular bone volume and trabeculae number compared with wildtype and Rac2‐null mice. This unique mouse model has shown for the first time that Rac1 and Rac2 play different and nonoverlapping roles during osteoclastogenesis and will be useful for identifying the key roles played by these two proteins during the multiple stages of osteoclast differentiation. Conclusions: Rac1 and Rac2 play different and nonoverlapping roles during osteoclastogenesis. This model showed that Rac1 is the key Rac isoform responsible for regulating ROS generation and the actin cytoskeleton during the multiple stages of osteoclast differentiation. 相似文献

We compared knee arthrotomy closures using interrupted biodegradable sutures and running bidirectionally barbed sutures in cadaveric specimens subjected to cyclic loading. During the initial 2000 flexion cycles, both groups maintained closure and no suture ruptured. Suture throws were then sequentially cut to weaken the repairs, and the knees were cyclically flexed after each cut. Both types of suture repairs survived the cutting of the first throw or stitch and subsequent cyclical testing. However, there was a significant difference in the repairs after multiple cuts (log-rank test, P < .003). None of the knees in the interrupted suture group survived more than 3 cuts, whereas in the barbed repair group, it took the severing of as many as 7 throws for failure to occur. 相似文献

Background Partial nephrectomy is currently the standard treatment for clinical T1 renal neoplasms, as it can provide oncologic outcomes equivalent to radical nephrectomy. The aim was to evaluate the efficacy of self-retaining suture (SRS) in renorrhaphy technique in retroperitoneal laparoscopic partial nephrectomy (LPN) for a single renal mass of moderate or high complexity by assessing peri-operative outcomes. Methods A retrospective analysis was done of 64 patients between 2010 and 2012 for complex renal mass (RENAL score 〉7) in whom retroperitoneal LPN was performed with two layers using continuous knotless barbed suture (Quill PDO SRS group; n=34) and absorbable vicryl (non-SRS group; n=30), respectively. Cases were matched for RENAL score. All the surgical procedures were performed by the same surgeon with experience of more than 500 cases of LPN. Comparisons were made in patients and preoperative outcomes and peri-operative complications between SRS group and non-SRS group. Results Mean warm ischemia time (WIT) in SRS group was less than non-SRS group (18.0 vs. 24.8 minutes, P=-0.021). Renorrhaphy suture cost in SRS group was lower than non-SRS group ($269.6 vs. $335.8, P=0,001). There were no significant differences between the two groups for postoperative changes in creatinine and estimated glomerular filtration rate and the rate of peri-operative complications. Conclusion SRS was safe for complex renal tumor with two layers, continuous and unknot suture, during LPN and would reduce the WIT and renorrhaphy suture cost significantly. 相似文献
