Long-term Results of Endoscopic Percutaneous Suture Lateralization for Newborns with Bilateral Vocal Cord Paralysis.

Bilateral vocal fold paralysis (BVFP) is a critical condition in newborns, which may present with significant airway distress necessitating tracheostomy. The purpose of this study is to report the safety and effectiveness of endoscopic percutaneous suture lateralization (EPSL) for newborns with BVFP, and evaluated the long-term results and the stability of the lateralization. A review of patients undergoing EPSL for BVFP at our institutions was performed between October 2018 and June 2023. Preoperative and postoperative clinical information was collected. The functional outcomes of the surgery in terms of breathing, voice, and swallowing were evaluated and recorded. Twenty seven patients were included, with a median age at diagnosis of 12 days (range, 1-33 days). The maximum follow-up is for 5 years. EPSL was successful in 77.8% of cases, effectively avoiding the need for tracheostomy. Dyspnea was relieved within a month after surgery, enabling patients to tolerate oral feeds within 2 months after surgery. Notably, some patients experienced a return of vocal fold function, particularly in successful EPSL cases, underlining the procedure's efficacy. Minor complications, including granulation tissue and wound infection, were observed but were manageable. Major complications were notably absent. The results are durable and stable at long-term follow-up. EPSL for BVFP is a relatively simple, minimally invasive, non-destructive, safe, and effective procedure in newborns, which may avoid the need for a tracheostomy, preserves the laryngeal framework, and does not affect the natural recovery of vocal cords.

Advancing Preservation Rhinoplasty: The J-Suture Technique for Refining the Middle Third of the Nose.

This article introduces a novel technique for refining the middle third of the nose in preservation rhinoplasty, adhering to the principles established by Teoman Dogan. The technique, applicable through both open and closed approaches, maintains the integrity of the nasal dorsum. The J-suture technique is particularly significant for addressing the widening of the middle third of the nose, a common issue in preservation rhinoplasty. This technique utilizes an absorbable percutaneous suture, allowing for the approximation of the upper lateral cartilages and thus thinning of the middle third of the nose. We discuss the technical aspects and advantages of the J-suture, emphasizing its simplicity, predictability, reproducibility, and ease of execution. The technique, requiring minimal training, can be adopted by any surgeon practicing preservation rhinoplasty. The J-suture represents a significant advancement in preservation rhinoplasty, providing a practical solution for enhancing nasal aesthetics while minimizing surgical trauma and promoting patient well-being.

Innovative Percutaneous 3-Stitch Suture Technique for Site Closure in Venoarterial Extracorporeal Membrane Oxygenation Decannulation Without Direct Artery Repair: A Case Series.

No previous studies have reported the use of a percutaneous suture technique performed by bedside intensivists for site closure during decannulation without direct artery repair in venoarterial extracorporeal membrane oxygenation (VA-ECMO) cases. Thus, the objective of this study was to evaluate the safety and effectiveness of this alternative approach. This retrospective study included 26 consecutive patients who underwent percutaneous VA-ECMO decannulation at Maoming People's Hospital. Bedside percutaneous suture technique performed by intensivists facilitated cannula site closure. Primary outcome was successful closure without additional interventions. Secondary outcomes included procedural time, surgical conversion rate, complications (bleeding, vascular/wound complications, neuropathy, lymphocele), procedure-related death. Follow-up ultrasound were conducted within 6 months after discharge. All patients achieved successful site hemostasis with a median procedural time of 28 minutes. Procedure-related complications included minor bleeding (7.7%), acute lower limb ischemia (15.4%), venous thrombus (11.5%), minor arterial stenosis (7.7%), wound infection (4.2%), delayed healing (15.4%), and wound secondary suturing (6.3%). No procedure-related deaths occurred. Follow-up vascular ultrasound revealed two cases (7.7%) of minor arterial stenosis. The perivascular suture technique may offer intensivists a safe and effective alternative method for access site closure without direct artery suture during ECMO decannulation.

Ultrasound-guided Percutaneous Achilles Tendon Repair

There is no consensus as to the standard treatment of ruptured Achilles tendon. In this paper, we present an innovative method of treating Achilles tendon rupture. Ultrasound-guided percutaneous Achilles tendon repair is a minimally invasive method in the treatment of Achilles tendon rupture. This study aims to assess the feasibility and effectiveness of the procedure in treating ruptured Achilles tendons and in minimizing the complications of surgical percutaneous suturing. Thirty-four patients were treated for Achilles tendon rupture using a percutaneous suturing method under the control of ultrasound. The average follow-up was ~22 months with good and excellent results. As the sural nerve can be easily displayed by high-frequency real-time ultrasonography, the percutaneous repair of the Achilles tendon rupture can be aided by intraoperative ultrasound. The presented method is a quick and efficient surgery, which allows the treatment of torn Achilles tendons in a low-invasive way. The outcomes of this method are promising and enable the reduction of complications of the classic suturing methods. Level of Evidence: Diagnostic Level IV.

A comparative biomechanical study of the krackow suture technique with three common percutaneous suture techniques in the treatment of Achilles tendon ruptures

BackgroundThe aim of this study was to compare the biomechanical resistance under tensile forces of the Krackow suture technique with the frequently used Dresden, Carmont & Maffulli, and Ma & Griffiths percutaneous repair techniques in bovine models of Achilles tendon rupture. MethodsTransverse Achilles tendon rupture models were created from 4 cm proximal of the calcaneal insertion point in a total of 20 bovine Achilles tendon specimens. These were randomly allocated to 4 groups and repaired with configurations appropriate to the Dresden, Carmont & Maffulli, Ma & Griffiths and Krackow techniques. Failure mechanisms were recorded with force values (as Newton units) creating a 5 mm gap and load to failure under tensile loading at a rate of 10 mm/sec in a static testing device. ResultsIn the Dresden technique group, the force required for a 5 mm gap was mean 41.21 ± 13.19 N and for load to failure, mean 193.83 ± 30.16 N, which were evaluated as statistically significantly higher than in the other techniques (p < 0.05). The lowest values were determined in the Ma & Griffiths technique group (5 mm gap: 11.06 ± 8.12 N, load to failure: 97.73 ± 29.60 N) but these were not significantly lower than the values in the Krackow and Carmont & Maffulli technique groups (p > 0.05). ConclusionThe results of this study showed that the Dresden technique was biomechanically superior against tensile forces compared to the Krackow technique, and the other frequently used percutaneous techniques of Carmont & Maffulli and Ma & Griffiths.

Laparoscopy-assisted percutaneous correction of abdominal wall defects in the umbilical region in a cadaveric model of bovine fetus.

Abdominal wall defects in calves are commonly diagnosed and treated via laparotomy. This technique has witnessed several advancements in the management of these disorders. This study aimed to create a study model and evaluate the feasibility of video-assisted percutaneous correction of abdominal wall defects in bovine fetuses (corpses) compared with the conventional technique. Sixteen bovine fetuses from pregnant cows slaughtered in slaughterhouses were included in this study. The fetuses were categorized into the control group (CG, n = 8), which was subjected to umbilical abdominorrhaphy via laparotomy, and the video-surgical group (VG, n = 8), which received video-assisted percutaneous sutures with two lateral accesses on the right flank. An abdominal wall defect was created in the VG group to generate a study model, which was corrected using the laparoscopic technique. The procedures were performed in two steps. The first step consisted of creating an abdominal wall defect in the umbilical region by laparoscopic approach in an iatrogenic manner (Step 1: E1). The second stage consisted of conventional abdominorrhaphy of the umbilical region wall defect in the CG group and video-assisted percutaneous suturing of the edges of the iatrogenic abdominal wall defect in the VG group, until reversal of the laparoscopic accesses (Step 2: E2). Step 1 showed no statistically significant difference between the two groups. However, a significant statistical difference (p < 0.0001) was observed between the two groups in step 2. The surgical time of step 2 was longer in the CG group (33.10 ± 0.43 minutes) than that in the VG group (10.13 ± 0.68 minutes, p < 0.0001), and the total surgical time was also longer in the CG group (38.48 ± 0.35 minutes) than that in the VG group (15.86 ± 0.67 minutes). The proposed laparoscopic technique allowed the creation of a study model for video-assisted percutaneous suturing with two portals and reduced the surgical time compared with the conventional technique. However, this method needs to be studied further in live animals.

P292 “CAN MIXED REALITY IMPROVE THE RESULTS OF TAVI?”

Abstract Background and Aim: Although the rate of TAVI–related complications has consistently reduced during the last decade, vascular complications still occur, and can be serious. Mixed reality (MR) can be defined as a three–dimensional real world simulation allowing the user to directly interact with it. The present study was designed to explore the potential of MR in facilitating the vascular access and navigation with large–bore devices. Methods 3D holograms were generated from the CT’s of 20 TAVI patients (age 81.2±6.8 years, STS score 5.1±2.1) and made available to 2 surgeons in training. Different layers were generated: Skin, Arterial tree, and Calcium. A needle simulator was also available. The vascular puncture was echo guided. 2 percutaneous suture system were used to secure the hemostasys. Results All the procedures were carried out through the planned access. In 2 patients intravascular lythoplasty was used. There were no vascular complications, and procedural success was 100%. A single puncture was necessary to obtain vascular access in 19/20 patients and in 2 cases the echo was not used, and the operator decided to switch to angio–guided puncture due to the bad quality of the echo images that were in contrast with MR. Conclusion MR can be used to predict the optimal puncture site for TAVI. The interactive 3D holograms can be used to identify relevant repere on the skin and to reduce the rate of vascular complications and could become a powerful tool for procedural planning, training and remote proctoring.

Internal Fixation of Redistributed Orbital Fat in Transconjunctival Lower Eyelid Blepharoplasty.

Fat redistribution combined with release of the tear trough ligament in transconjunctival lower blepharoplasty is widely performed to correct lower eyelid bags and tear trough deformities, but suturing the released fat in such a narrow, dissected space remains a challenge. The purpose of this study was to introduce a new surgical technique of internal fixation that advances and sutures the pedicled orbital fat firmly to the midcheek through premaxillary and prezygomatic spaces. Twenty-two patients (age range, 22 to 39 years) with predominant orbital fat prolapse and tear trough deformity without noticeable lower eyelid skin laxity were treated with this method, all of whom had impressive correction of the eyelid bags and tear trough deformities and were pleased with the aesthetic results during an average follow-up of 11.8 months (range, 10 to 14 months). No patient had postoperative hematoma, ectropion, or midface numbness. The maneuver of internal fixation of redistributed orbital fat provides a novel and safe approach to correct eyelid bags and tear trough deformities without additional percutaneous sutures in transconjunctival lower eyelid blepharoplasty.

Percutaneous suture lateralization for bilateral vocal fold paralysis - How we do

Bilateral abductor cord paralysis is rare. But it requires urgent surgical intervention due to upper airway obstruction at glottis level. Percutaneous suture lateralization seems to be a safe and effective treatment, which enable patients to be devoid of tracheostomy without significant influence on phonation or swallowing function. Here we explain the technique of suture lateralization of vocal cord with the available resources.

Outcomes of endoscopic percutaneous suture lateralization for neonatal and infantal bilateral vocal ford paralysis.

Bilateral Vocal Fold Paralysis (BVFP) is a rare but significant resource of respiratory distress in neonates and infants. The objective of this study was to evaluate the efficacy and functional outcomes of Endoscopic Percutaneous Suture Lateralization (EPSL) for the treatment of BVFP in neonates and infants. A case series study of nine patients undergoing EPSL for BVFP between January 2019 and June 2021 was conducted. All patients were candidates for tracheostomy prior to EPSL. Demographic features including gender, age at diagnosis and surgery, main symptoms, airway comorbidities, airway support, and etiology were collected preoperatively. Patients were evaluated for breathing, swallowing and phonation postoperatively. Surgical success was defined as the ability to avoid tracheostomy. Functional Endoscopic Evaluation of Swallowing (FEES) was conducted to identify aspiration. Voice evaluation was based on clinical observation. Nine patients underwent ten EPSL procedures (one in the left vocal fold, and nine in the right vocal fold). Eight patients (8/9) were able to successfully avoid tracheostomy and feed orally without aspiration after the procedure. One patient experienced clinical improvement in respiratory support requirements and underwent laparoscopic nissen and gastrostomy tube placement. At the last follow-up, two patients regained normal voice, two patients had mild dysphonia, and five patients had moderate dysphonia. Five patients showed partial return of the contralateral vocal fold function. EPSL is an effective and safe treatment for neonatal and infantal BVFP, which enables patients free from tracheostomy without significant impact on swallowing function or phonation. Level 4.

Computed tomography guided tailored approach to transfemoral access in patients undergoing transcatheter aortic valve implantation.

Transfemoral approach (TFA) is the most common access route for transcatheter aortic valve implantation (TAVI). Percutaneous femoral access (PA) is preferred over the surgical approach (SA), however, may be associated with a higher risk of access site complications. Thus, we aimed to assess outcomes of computed tomography-guided tailored approach to percutaneous and surgical TFA in patients undergoing TAVI. We evaluated data of 158 patients, who underwent TAVI via femoral route between January 2017 and December 2018. In the PA group, vascular closure was performed with the use of two percutaneous suture devices and an additional mechanical seal device. We compared complications rate and outcomes. Of the 158 patients (92%; mean age 79.6 years, 60.8% female), in 92 (61%) patients PA was performed and in 66 (39%) patients SA was used. Median (interquartile range) radiation exposure as well as contrast volume dose was higher in the PA group compared to the SA group 614.0 (410.0; 1104.0) mGy vs. 405 (240.5; 658.0) mGy (p < 0.001) and 150.0 (120.0; 180.7) mL vs. 130.0 (100.0; 160.0) mL (p = 0.04), respectively. Bleeding complications were similar in the PA group 11 (12.2%) compared to 5 (8.62%) in the SA group (p = 0.48). Median length of hospital stay was also similar in the PA and the SA group 6.00 (5.00; 8.00) days vs. 6.00 (4.00; 8.00) days, respectively (p = 0.31). Computed tomography-guided PA in TAVI may provide comparable procedural outcomes compared to the SA, despite a higher radiation dose and the use of contrast dye, while being less invasive.

Percutaneous Suture - Closure Device Used for Iatrogenic Carotid Artery Injury Management: Case Report and Review of Literature.

Accidental carotid artery injury is an uncommon but serious central venous catheter insertion complication. Hemostasis might not be readily achieved by manual compression; therefore, surgery or endovascular treatment remains the mainstay for accidental carotid artery injury. However, not all patients are suitable candidates for surgery.Vascular closure devices are widely used in femoral arteries to achieve hemostasis and early ambulation. The use of vascular closure devices is occasionally reported in other vascular beds. Here we present a case of an iatrogenic left common carotid artery injury treated by vascular closure device, which is of help in the future management of this complication.

A New Technique of Achilles Tendon Rupture Repaired by Double Transverse Mini‐incision to Avoid Sural Nerve Injury: A Consecutive Retrospective Study

Percutaneous suture is a classic technique used in Achilles tendon repair. However, the complication rates surrounding the sural nerve remain relatively high. Modified percutaneous repair technology can effectively avoid these complications; however, the surgical procedure is complicated. Hence, the present study was conducted to describe a redesigned repair technique for the Achilles tendon able to avoid sural nerve injury and reduce the complexity of the procedure. Data of patients with acute primary Achilles tendon rupture at our hospital from January 2019 to May 2020 were included. Subjects with expectations for surgical scarring underwent a minimally invasive-combined percutaneous puncture technique. The surgical time, requirement for conversion to other technologies, and length of postoperative hospitalization were investigated to assess efficacy. The American Orthopedic Foot & Ankle Society (AOFAS) score and the Arner-Lindholm scale (A-L scale) were used to assess postoperative clinical outcomes (> 24 months). During the 2-year follow-up, MRI was performed to observe the healing of the Achilles tendon. In addition, subjective satisfaction with surgical scar healing was recorded. Twenty consecutive subjects with an average follow-up of 28.3 ± 4.5 months (range, 24-41) met the inclusion criteria. None of the 20 enrolled patients required a converted surgical approach. The mean surgical time was 26.9 ± 6.47 min (range, 20-44). None of the patients experienced dysesthesia or anesthesia around the sural nerve. No signs of postoperative infections were observed. MRI data showed that the wounds of the Achilles tendon healed completely in all the subjects. The AOFAS score increased from 55.6 ± 11.07 (range, 28-71) preoperatively to 97.8 ± 3.34 (range, 87-100) at the last follow-up. The A-L scale showed that 90% of the subjects (n=18) presented as excellent and 10% of the subjects (n=2) presented as good, with an excellent/good rate of 100%. Moreover, subjects' satisfaction for surgical scars was 9.1 ± 0.78 (upper limit, 10). The results indicate that this technique can achieve good postoperative function, a small surgical incision, and high scar satisfaction. In addition, this technique should be widely used in suturing Achilles tendon ruptures.

Management of high-output cardiac failure caused by head and neck AVMs: Percutaneous suture-assisted ethanol and coil embolotherapy.

The aim of this study was to describe the treatment technique, outcomes, and complications of Schobinger stage IV head and neck arteriovenous malformations (HNAVMs) with associated high-output cardiac failure (HOCF) using ethanol and coils with the percutaneous suture technique. From January 2015 to December 2019, 19 patients who had HNAVMs with associated HOCF were treated first with a percutaneous suture of the remarkably dilated dominant drainage vein (RDDOV) and subsequent embolization with coils and ethanol. The percutaneous suture of RDDOV was preferred to be performed, followed by the deployment of coils and the injection of absolute ethanol via transarterial approach, direct puncture approach, or both of them. Treatment outcomes and complication rates were evaluated at follow-up. A total of 19 patients who experienced HNAVMs with HOCF received 19 percutaneous suture procedures and 84 embolization procedures with ethanol and coils. Complete or >90% shunt reduction of the AVM was achieved in 16 patients. Notably, 19 patients with New York Heart Association (NYHA) stage II improved to stage I, and the symptom of dyspnea disappeared after embolization. The symptoms of five patients with bleeding disappeared. All patients presented with cosmetic concerns; Four were cured, and eight had a clearly recognizable improvement. Of note, 19 (100%) patients presented with impairment of daily life, which was resolved. The minor complications were encountered and recovered by the self. No major complications occurred. This study provides evidence that ethanol and coil embolotherapy is effective and safe in treating HOCF caused by HNAVMs with acceptable complications in these cases. The percutaneous suture technique for RDDOV management can act as an adjunct for embolotherapy.

S2481 Closure of Refractory Gastrocutaneous Fistula With Endoscopically Guided Percutaneous Suturing With the Use of SpyBite Biopsy Forceps

Introduction: Persistent gastrocutaneous fistula (GCF) is a rare but well-known complication of long-term Percutaneous Endoscopic Gastrostomy (PEG) tube use. To avoid invasive surgery, endoscopic closure has been used as an initial step for treatment but is not always successful. We report a case of successful GCF closure with a novel endoscopically guided percutaneous suturing technique using the SpyBite biopsy forceps. Case Description/Methods: Our case is a 28-year-old male with a history of cystic fibrosis (CF) complicated by malnutrition, requiring PEG tube placement since childhood. After starting CF therapy with elexacaftor/tezacaftor/ivacaftor and achieving optimal nutritional status, his PEG tube was removed. Unfortunately, he developed a persistent GCF. Initial attempts at closure with over-the-scope-clip and endoscopic suturing failed. The decision was made to proceed with GCF closure by endoscopically guided percutaneous suturing using the SpyBite forceps. Under endoscopic guidance, 2 16G long angiocaths were advanced into the gastric lumen, one caudal and one cranial to the fistula tract in a sterile fashion. A 2-0 silk suture was advanced through one angiocath and externalized using SpyBite biopsy forceps through the other angiocath. The angiocaths were then removed over the suture and the loop was tied down using a surgical knot. This process was repeated 2 more times along the fistula tract, 5mm from each other. Internal closure of the GCF was then performed using endoscopic suturing. One interrupted and 2 running sutures were placed along the border and cinched to reinforce the site. There were no immediate adverse events or delayed skin inflammation. The patient had no further leakage from the GCF site at follow-up 2 weeks later (Figure). Discussion: With the emergence of novel CF therapies, the dependence on feeding tubes has decreased. Unfortunately, these patients are at high risk of GCF formation after PEG tube removal. Given the difficulty in closing GCF, we advocate a multimodality approach, as described here, using transcutaneous and endoscopic suturing. In previously described endoscopically guided percutaneous suturing, the suture loop is externalized through the GCF tract or the mouth. Our technique differs in using SpyBite forceps to externalize the suture through a second catheter. This method is simple and provides a safe and effective alternative for the closure of refractory GCFs.Figure 1.: A-B: Gastrocutaneous fistula before (A) and after closure (B). C-D: 2-0 silk suture inserted through the angiocath and SpyBite forceps inserted through the second angiocath. The suture was grasped with SpyBite forceps and pulled through the second angiocath to form a loop (C: external view, D: endoscopic view) E-F: The suture was pulled externally, and a surgical knot was performed (E: external view, F: endoscopic view).

Percutaneous Internal Ring Suturing (Pirs): A Minimally Invasive Procedure in Pediatric Inguinal Hernia Repair

Objective Percutaneous internal ring suturing (PIRS) is a single port laparoscopic technique used to repair pediatric indirect inguinal hernia. Unlike the open method, which is the gold standard of the hernia repair, this technique is still new in the fraternity and not many centers practiced it. We applied this technique on our patients and we found that the duration of surgery was shortened, smaller surgical incision, lesser complications and early discharges. Methods Patient selection was done based on several criteria, term baby with no anomalies, indirect inguinal hernia, and male baby with a thin abdominal wall. The baby was put under general anesthesia via endotracheal intubation. One-centimeter infraumbilical incision was made and a 3mm 70◦ scope is inserted after a pneumoperitoneum achieved. With the guidance of the scope, a spinal needle with a Prolene 2-0 was punctured and threaded in on the medial edge of the internal inguinal ring (Figure 1-3). Once the sutures in, the needle is withdrawn. Similarly, another Prolene 2-0 is punctured and threaded in on the lateral edge of the internal inguinal ring (Figure 4). This time, the needle is looped into the first suture (Figure 5). After the withdrawal of the needle, the sutures were tightened and ligated (Figure 6). Laparoscopy is used to inspect that the internal ring is snugly closed without the entrapment of the vas or the cord structures. Once ligated, the scope is removed and the port site is sutured using a purse-string suture. The patient is extubated, observed in the general ward till afternoon and was discharged home after passing flatus, stool, and urine.

The Twizzler: a modified primary closure for distal lower extremity wound reconstruction utilizing a dynamic winch stitch.

Management of lower extremity wounds following successful tumor excision presents multiple challenges. Distal lower extremity integument is highly prone to edema often lacks adequate skin laxity for standard primary closures. The closure must be resilient enough to withstand mobility. As a result, optimal reconstruction may include skin grafting, rotational flaps, free tissue transfers, healing by second intention, or some combination. These methods may involve multiple steps in reconstruction, a prolonged recovery period, increased cost, and higher infection risk. We propose a modified primary closure that takes advantage of the visco-elastic properties of the skin without introducing additional components or steps. This technique is initiated with percutaneous suture in order to intermittently stretch the skin with constant tension. This load cycling allows for lower extremity skin to stretch over time and ultimately reduce wound edge tension, allowing for ease of absorbable suture placement. The Twizzler technique is cost-effective, uses readily available supplies, and effectively closes relatively large defects on the lower extremities.
