Supermicrosurgical Suture-Stent Technique for A Lymphaticovenular Bypass.

ABSTRACT:

Background

Lymphaticovenular anastomosis (LVA) is a challenging procedure and requires a sophisticated supermicrosurgical technique. The aim of this study was to evaluate and establish a discrete supermicrosurgical anastomosis method using the "suture-stent technique".

Methods

Forty-eight LVA sites of twenty patients with lower extremity lymphedema who had undergone LVA between July 2020 and January 2021 were included in this study. LVA was performed with the conventional technique or with the suture-stent technique. The patency of the anastomoses was evaluated using an infrared camera system intraoperatively. The success rate on the first try and the final success rate for each group were compared.

Results

After full application of the exclusion criteria, 35 LVAs of 16 patients including 20 limbs were included in the analysis. The ratio of good patency findings after anastomosis in the suture-stent technique group was 100%. The incidences of leakage or occlusion on the first try were statistically greater in the conventional technique group (29.4%) than in the suture-stent technique group (0%) (p = 0.0191). All anastomoses achieved good patency in the final results.

Conclusion

With its minimal risk of catching the back wall during the anastomosis, the suture-stent technique can be considered an optimal anastomosis option for LVA.

Continuous Suture Technique for Aortic Valve Replacement Shortens Cross-Clamp and Bypass Times.

Project description:The interrupted noneverting mattress suture technique is typically used in conventional surgical aortic valve replacement. The continuous suture technique, although faster, has been associated with a higher incidence of paravalvular leak. Using a slightly modified technique to minimize this risk, we investigated whether continuous suturing would shorten aortic cross-clamp time in aortic valve replacement in comparison with interrupted suturing. We reviewed the cases and compared the perioperative data of 60 consecutive patients in Japan and Australia (35 men and 25 women; median age, 70 yr) who had undergone aortic valve replacement with or without septal myectomy. The continuous suture technique had been used in 41 patients (Group CS) and the standard interrupted suture technique in 19 (Group IS). The groups were similar in age, sex, pathologic valvular conditions, and operative urgency. In Group CS, aortic cross-clamp time (47 vs 63 min; P=0.0001) and cardiopulmonary bypass time (76 vs 89 min; P=0.04) were significantly shorter. Neither group had early paravalvular leak. Using our continuous suture technique safely shortened aortic cross-clamp time during surgical aortic valve replacement.

Arthroscopic suture anchor tenodesis: loop-suture technique.

Project description:With advancements in arthroscopic surgery, arthroscopic biceps tenodesis with suture anchor recently has been reported to be a reasonable option for the treatment of biceps pathologies, especially for those that are symptomatic or accompanied by a rotator cuff tear. We introduce our technique of arthroscopic biceps tenodesis with suture anchor that we call the loop-suture technique, which is constructed with 1 loop strand and another sutured strand. This technique can help to improve biceps grip and simultaneously minimize longitudinal splitting of the tendon. In addition, it is relatively simple and can be performed with the use of conventional devices and arthroscopic portals used for rotator cuff repair, without the formation of additional portals or a separate incision for the tenodesis.

Vertical Continuous Meniscal Suture Technique.

Project description:Meniscal injuries are common in the population, representing the major cause of functional impairment in the knee. Vertical longitudinal injuries of the meniscus can be stable or unstable. When extensive, they are commonly unstable and can lead to clinical signs of significant functional disability. Vertical longitudinal injuries have the best prognosis for repair, especially when occurring in the meniscal periphery, called the red-red zone. A recently developed type of meniscal suture device called Meniscus 4 A-II enables the surgeon to perform a meniscal suture from the inside-out continuously, reducing surgical time. Because it allows the surgeon to use a single and inexpensive device to repair the entire injury, costs are significantly reduced. Here, an approach to carry out continuous meniscal repair with vertical sutures is described. This technique warrants excellent stability to the meniscal repair, increasing the chances of a successful outcome. We believe that the popularization of the repair technique from the inside out using the Meniscus 4-All device will help many surgeons around the world save menisci that otherwise would have a great chance of being excised, since it is a cheap, reproducible, and easy-to-handle device.

Hybrid suture technique vs simple suture technique for antero-inferior labral tears: Two years' clinical outcomes.

Project description:BackgroundWe previously reported a hybrid suture technique, wherein mattress and simple suturing are used to create Mason-Allen configuration, with low recurrence rates. This comparative study looking at the two years' clinical outcomes of arthroscopic anterior labral repair using the hybrid suture technique versus simple suture technique.MethodsWe identified 103 patients who underwent arthroscopic anterior labral repair from 2010 to 2015 with 2-year follow-up. The patients were categorized into two groups: hybrid suture technique (65 patients) and simple suture technique (38 patients). Clinical outcomes measures included UCLA shoulder score, Constant Shoulder Score, Numerical Pain Rating Scale, and Oxford Instability score.ResultsMean age of the patients was 27.02 ± 9.76 years (17-63), with 91 males and 12 females. At 24 months, both groups showed significant improvement in post-operative clinical scores compared to pre-operation. The patients in hybrid sutures technique demonstrated significant improvement in Constant Shoulder Score, UCLA shoulder score and Oxford Instability score compared to simple suture group at 3 months follow up. (121.98 ± 21.05 vs 109.32 ± 21.15, p < 0.05; 65.5 ± 19 vs 57.4 ± 17.6, p < 0.05; 27.3 ± 5.7 vs 23.7 ± 5.0, p < 0.05; 29.3 ± 8.9 vs 33.4 ± 8.2, p < 0.05). The postoperative recurrence rate was comparable between both groups (hybrid suture group 7.81% vs simple suture group 7.84%).ConclusionsArthroscopic anterior labral repair with hybrid suture technique offers significant early improvements in clinical scores and low recurrence rate compared to simple suture technique at 2-year follow-up.Level of evidenceLevel III; Retrospective Cohort Design; Treatment study.

Tension band wiring versus suture anchor technique in patellar inferior pole fracture: Novel double row suture anchor technique.

Project description:IntroductionPatellar inferior pole fractures are challenging to obtain sufficient fixation. The purpose of this retrospective, case-controlled study was to compare the clinical and radiological outcomes between tension band wiring (TBW) and our novel double-row suture anchor (SA) technique in patellar inferior pole fractures.Materials and methodsThis retrospective study included patients who underwent TBW or SA fixation for patellar inferior pole fractures from 2015 to 2019. A total of 63 patients were divided into two groups according to the surgical procedure: the TBW group (n = 35) and the SA fixation group (n = 28). The visual analog scale score, range of motion of the knee, Lysholm score, Kujala patellofemoral score, and patient satisfaction score were evaluated for clinical and functional outcomes. Radiological outcomes included the time to radiological union, loss of reduction, and the Insall-Salvati (IS) ratio.ResultsSignificant improvements in clinical outcomes were observed in both groups with no significant differences. Bone union was achieved in all patients, and there was no significant difference in the time to radiological union and the IS ratio between the two groups. All patients in the TBW group underwent additional surgeries for implant removal. However, none of the patients in the SA group underwent implant removal or experienced skin irritation.ConclusionOur novel double-row SA technique could provide comparable fixation strength and good clinical outcomes, with fewer complications in patellar inferior pole fractures. This novel SA technique is a satisfactory alternative treatment for patellar inferior pole fractures.

Continuous Meniscal Suture Technique of the Knee.

Project description:The menisci are fibroelastic structures interposed between the articular surfaces of the femur and tibia. They absorb impact and transmit load. Meniscal injury may compromise function and cause rapid joint degeneration, leading to the development of secondary osteoarthritis. Surgical treatment of meniscal injury is usually performed by arthroscopy, and meniscectomy or meniscal suture may be associated with such treatment. Meniscal suture should be considered when the injury compromises the proper functioning of the meniscus to recover its anatomy and function. Different meniscal suture techniques exist; the most widely used are the inside-out, outside-in, and all-inside techniques. The gold-standard repair technique is the inside-out technique. A drawback of this technique is the need to alternate between intra- and extra-articular structures for every stitch, which makes it even more laborious. We describe the continuous meniscal suture technique, also called "meniscal stitching," for a medial meniscal bucket-handle injury. This technique is performed from the inside out and allows the surgeon to perform multiple stitches with the same thread quickly and effectively. This surgical technique is performed using a single meniscal suture device that was developed by our group, called the "Meniscus 4 A-II" device.

Needle Adjustment Free (NAF) running suture technique (PAN suture) in laparoscopic partial nephrectomy.

Project description:BackgroundIt is proposed a new running suture technique called Needle Adjustment Free (NAF) technique, or PAN suture. The efficiency and the safety were evaluated in laparoscopic partial nephrectomy.MethodsThis new running suture technique avoids the Needle Adjustment method used in traditional techniques. The new continuous suture technique (11 patients) was compared with the traditional continuous suture method (33 patients) used in both transperitoneal and retroperitoneal laparoscopic partial nephrectomy (LPN) in terms of suture time (ST), warm ischemia time (WIT), blood loss (BL), open conversion rate and post-op discharge time, post-op bleeding, post-op DVT, ΔGFR (affected side, 3 months post-op). Differences were considered significant when P < 0.05.ResultsST in the PAN suture group was 30.37 ± 16.39 min, which was significant shorter (P = 0.0011) than in the traditional technique group which was 13.68 ± 3.33 min. WIT in the traditional technique group was 28.73 ± 7.89 min, while in the PAN suture group was 20.64 ± 5.04 min, P = 0.0028. The BL in entirety in the traditional technique group was 141.56 ± 155.23 mL, and in the PAN suture group was 43.18 ± 31.17 mL (P = 0.0017). BL in patients without massive bleeding in the traditional technique group was significantly greater than in the PAN suture group at 101.03 ± 68.73 mL versus 43.18 ± 31.17 mL (P = 0.0008). The open conversion rate was 0 % in both groups. There was no significant difference between the two groups in postoperative discharge time, post-op bleeding, post-op DVT, ΔGFR (affected side, 3 months post-op).ConclusionsThe NAF running suture technique, or PAN suture, leading to less ST, WIT and BL, which was shown to be more effective and safer than the traditional technique used for LPN. A further expanded research with larger sample size is needed.

Arthroscopic Suture Fixation of Os Acetabuli With Absorbable Suture Anchors-A Double-Pulley Technique.

Project description:Os acetabuli is a bone fragment with unknown origin and isolated at the acetabular rim that may be associated with cam-type femoroacetabular impingement. If this bone fragment is too large and threatens the stability of the hip joint after resection, fixation would be recommended. However, conventional rigid fixation with metal screws has some disadvantages. We describe an arthroscopic suture fixation of the Os acetabulum with absorbable anchors penetrating the bone fragment and secured by tying knots in a double-pulley fashion simultaneously. This technique provides a new feasible solution for the fixation of Os acetabuli, avoiding any metal implants and potential damage to the joint.

Subscapularis repair with the suture shuttle loop technique.

Project description:Successful techniques for arthroscopic repair of subscapularis tendon tears have been previously described in the literature. Recommendations regarding portal placement, tissue mobilization, and suture passage have been published. We present a novel technique that uses a shuttle suture passed with the Viper suture passer (Arthrex, Naples, FL) through a standard anterior arthroscopy portal. The described technique easily passes a suture through the subscapularis tendon while the surgeon visualizes suture placement from the posterior portal.
