There are several general techniques for sling placement. Polyglycolic Acid Sutures | PGA-Sutures PGA-Suture for surgical application Coated, braided PGA is an excellent and well established synthetic absorbable suture, widely used for surgical applications. - Rapid Polyglycolic Acid (PGAR) is intended to be used in soft tissues where only short term wound support is required, and where rapid absorption of the suture is needed - Polyglactine 910 (PGLA) is suitable for cases in which a predictable absorption and good tensile strength is needed; the suture holds its tensile strength for approximately two or three weeks in the tissue Michael Mitchell MD, Richard Grady MD, in Ashcraft's Pediatric Surgery (Fifth Edition), 2010. The use of a 2–0 or 3–0 polyglycolic acid suture, as noted before, is recommended. It is extruded into thin filaments and braided into sutures in The specific gravities of PGA are 1.707 for a perfect crystal and 1.50 for a completely amorphous material (Chujo et al., 1967). Experimentation with absorbable polyesters led to the development of poly-l-lactic acid (PLA) and polyglycolic acid (PGA) as resorbable implantable devices. The tight molecular packing and the close approach of the ester groups are thought to stabilize the crystal lattice and contribute to the high melting point of PGA (224 227 °C). Immediate detumescence occurs, and a hematoma develops on the penile shaft. This procedure effectively narrows and lengthens the urethra. The tension necessary for urethral closure can be tested by manually compressing the bladder to observe for urethral leakage. Owing to its hydrolytic instability, however, its use has initially been limited. Polyglycolic Acid. Both d and l polymers are semicrystalline materials, whereas the optically inactive dL-PLA is always amorphous. A chondrocyte-seeded PLA/PGA polymer similar to Vicryl has been used in the “tissue engineering” of cartilage scaffolding. In these situations, a urodynamic catheter can be placed suprapubically at the time of the cystourethroscopic examination to be used later that day for the urodynamic evaluation. To overcome this problem, the use of copolymers of PGA and PLA has been studied. Penile fracture, although uncommon, demands immediate diagnosis and correction. Various types of sutures. Polyglycolic acid sutures absorb by simple hydrolytic mechanism and absorption is predictable. These tunica injuries should be surgically corrected and involve degloving the penis, controlling the bleeding, and reapproximation of the tunica albuginea with interrupted polyglycolic acid sutures. When used alone, poly(l-lactide) forms a strong crystalline lattice that takes months or years to undergo hydrolysis; mixtures of poly(l-lactide) with poly (d,l-lactide) resorb more quickly. In such cases, the sling tension may be increased slightly to maximize the likelihood of having a continent reconstructed sphincter. Bladder neck tapering is achieved by excising a wedge from each side of the bladder neck and proximal urethra (see Fig 58-4G). Jack S. Elder, Joao Luiz Pippi Salle, in Pediatric Urology, 2010. The anastomosis is then tested by filling the bladder with 300 cm3 of saline and observing for any possible leaks. With the bladder open, the bladder neck is mobilized using the Lottmann technique. The bladder neck may be funneled further with small vertical incisions along the cut edge of the lateral bladder walls. BNR requires adequate bladder capacity because some volume is lost during the procedure. This is often described as an “eggplant” deformity. For this reason, l-PLA is preferred for application where high mechanical strength and toughness are needed. Occasionally, a portion of the intersymphyseal band must be divided completely for good visualization. After transtrigonal/cephalotrigonal bilateral ureteral reimplantation, a strip of bladder mucosa 1.5 to 1.8 cm wide and 3.0 to 4.0 cm long is generated and the lateral bladder triangles are demucosalized.

Damato, ... Wallace S. Foulds, in, The muscles are resutured to their original insertions with 5–0 braided, Materials for absorbable and nonabsorbable surgical sutures, Frazza and Schmitt, 1971; Schmitt and Polistina, 1967; Katz and Turner, 1970, Anterior Approach to Robotic Radical Prostatectomy, Andrew C. Harbin MD, Daniel D. Eun MD, in, There are many descriptions of the vesicourethral anastomosis, including variations using braided, monofilament, and even barbed suture. PGA suture are available in dyed (violet colour suture) and also un-dyed versions from USP sizes 6-0 to USP size 2. The bladder neck may be funneled further with small vertical incisions along the cut edge of the lateral bladder walls. The nonviable parenchyma that extrudes freely into the scrotal space should be removed, and the tunica albuginea of the testicle should be approximated with a running polyglycolic suture. M.A. Occasionally, a portion of the intersymphyseal band must be divided completely for good visualization. More recent trends in management have involved wet-to-dry dressing changes to the exposed testicles, with grafting with split-thickness grafts once tissue bed is healthy. When traction is placed on each end of the sling, the graft has a tendency to curl or roll up. Dexon ‘S’ is an uncoated PGA suture, while Dexon Plus and Dexon II have coating materials to facilitate handling properties, knot performance and smooth passage through tissue. 58-4I). Consequently, fixation of the graft to the bladder neck in two to three places with 4-0 polyglycolic acid sutures is helpful (see Fig. (A mild inflammatory reaction may occur, which is typical of an endogenous reaction to foreign bodies) The present study details experience with the material in 120 patients in a variety of general surgical operations. PGA’s superior features over catgut are predictable absorption, outstanding tensile strength, in-vivo inertness and excellent handling properties. Andrew C. Harbin MD, Daniel D. Eun MD, in Prostate Cancer (Second Edition), 2016, There are many descriptions of the vesicourethral anastomosis, including variations using braided, monofilament, and even barbed suture. 【Warning】 ABSORBABLE POLYGLYCOLIC ACID FELT (1) Do not apply nor use in conditions where excessive tension and load act upon NEOVEIL ; nor should it be used in cases where it presses the region by its own weight when used for reinforcement. PGA has been known since 1954 as a tough fiber-forming polymer. Use of an epinephrine-soaked sponge during this dissection aids in hemostasis and visualization. PGA is the simplest linear polyester. A bladder capacity less than 60 mL under anesthesia or during urodynamic evaluation decreases the success of BNR. Postoperatively, urine is drained through a combination of ureteral stents, a suprapubic tube, and a 6-Fr urethral catheter. PGA suture have first launched in India by us under the Brand name Petcryl which provided the first Synthetic Absorbable Suture to the Indian market apart from Vicryl suture by Ethicon. synthetic absorbable suture an absorbable suture produced from strands of polymers; the most commonly used materials are polyglactin 910 (Vicryl) and polyglycolic acid (Dexon); the latter is more rapidly absorbed. Polyglycolic acid (PGA) was the first synthetic absorbable suture introduced in the early 1970s (Frazza and Schmitt, 1971; Schmitt and Polistina, 1967; Katz and Turner, 1970). ! However, others have described a cephalotrigonal technique that is particularly applicable to exstrophy patients because of the angle of ureteral entry into the bladder.88 The Marshall-Marchetti-Krantz (MMK) bladder neck suspension or a bladder neck wrap using rectus muscle or fascia or gracilis may be combined with BNR as well. PGA suture retain approximately 75% of PGA initial strength after two weeks. Numerous catalysts are available for this ring opening polymerization. A suprapubic catheter is left indwelling for 2 to 3 weeks before catheterization is initiated. 58-5C). When local skin is not available, split-thickness skin grafts can be used to cover the testicles and penis. Polyglycolic Acid Suture has been found to be non-antigenic, non-pyrogenic and elicit only mild tissue reactivity during the absorption process. Absorption of bio-absorbable suture occurs by hydrolysis ; beginning with loss of tensile strength followed by loss of mass. In incontinent children after CPRE or MSRE, a continence procedure is indicated when (1) the urethra is stricture free and capable of catheterization, if necessary; (2) under anesthesia, the bladder capacity has achieved a minimum volume of 60 to 85 mL; and (3) the child is mature enough to participate in the postoperative voiding program.87 This is typically around age 4 to 5 years. Distinctive Characteristics of PGA Suture: – Read more about pga sutures manufactured by Dolphin Sutures. Sculptra is a newly developed PLA product for midfacial soft tissue augmentation due to the wasting caused by protease inhibitors. Occasionally, trigonal tubularization must be combined with bladder augmentation because of small bladder capacity as most BNRs decrease bladder capacity because a portion of the bladder is used to create the continence mechanism.91 Stomach offers the best potential to preserve spontaneous volitional voiding in this group but places these children at risk of hematuria-dysuria syndrome, which can be especially troubling in the presence of persistent urinary incontinence and normal sensory innervation.92 Other intestinal segments may also be used depending on surgeon preference. These testicles heal after reconstruction and are useful for hormone production and cosmetic appearance. The neourethra is tubularized over an 8-Fr stent using interrupted or running polyglycolic acid sutures (4-0 or 5-0). A comparison of Dexon (polyglycolic acid) sutures with other commonly used sutures in an accident and emergency department G. L. Mouzas Accident and Emergency Centre, West Hill Hospital, Dartford, Kent, and Davis & Geck, Cyanamid of Great Britain Ltd, Gosport, Hants What are the different types of Sutures? Polyglycolic Acid Suture is indicated for use in general soft tissue approximation and/or … - Braided suture, monofilament.- Coated with polycaprolactone and calcium sterate - The absorption of this suture is complete within 70 days being absorbed by hydrolysis. Preoperative urodynamic evaluation should be considered because it allows detection of detrusor hyperactivity or atony as well as assessment of functional bladder capacity and leak-point pressures. Because they are manufactured by synthetic polymers, their resorption is slower and they will maintain the incision line with a tensile strength much longer than most suture materials. Two common uses include the renorrhaphy closure in partial nephrectomy and the vesicourethral anastomosis in radical prostatectomy. On occasion, the bulge of the repositioned uvula may appear prominent enough in the first few weeks that the surgeon is tempted to consider postoperative revision, but this seems to diminish with time. The resulting PGA polymer having Mw from 20 000 to 140 000 is suitable for fiber extrusion and suture manufacturing. Experimental studies have shown this substance to be a suitable suture material in animals. Jon B. Suzuki, Randolph R. Resnik, in Misch's Avoiding Complications in Oral Implantology, 2018. Testicular rupture is best diagnosed by ultrasonography, which will demonstrate areas of relative lucency of the echogenic patterns within the testicle parenchyma. Factors that increase the potential for the bladder to achieve adequate capacity before BNR include: Complete bladder emptying with institution of CIC if bladder emptying is incomplete. The Cohen technique is often employed. The urethral catheter is removed 7 to 10 days after the operation. With these methods, acceptable cosmetic and functional results can be expected. The conjunctiva is closed with 8–0 braided polyglactin sutures (Fig. To compensate for any muscle shortening, the distance from the suture knots to the limbus is measured before the muscle tendon is divided and also at the time of reinsertion so that a sling can be used if necessary. The introduction of the more hydrophobic PLA into the polymeric structure limits the water uptake and reduces the rate of backbone hydrolysis. A copolymer of PLA (82%) and PGA (18%) was developed that consistently demonstrated adequate initial strength and complete resorption after 9 to 15 months. The need for complete orchiectomy is not often necessary when injury results from blunt trauma, particularly if diagnosed within 48 hours of injury. Urethrography should be done to determine whether concomitant urethral injury is present. When the muscle insertion is located on the scleral flap, the reinsertion of the muscle is safer if a 1 mm stump of tendon is left in situ at the time of the disinsertion. For biomedical applications, stannous chloride dihydrate or trialkyl aluminum are preferred. Vicryl, being a Polyglactin material is made from made from copolymer of 90% Glycolide and 10% L-lactide but Petcryl suture are 100% glycolide. Ureteral stents are removed at 10 to 14 days after surgery. This has diminished the necessity of the thigh pouch technique, and delayed reconstruction. PGA's superior features over catgut are predictable absorption, outstanding tensile strength, invivo inertness and excellent handling properties. Charles D. Best, in Current Therapy of Trauma and Surgical Critical Care, 2008. RAPIDSuture is intended for use in soft tissue approximation where only short term wound support is required and where the rapid absorption of the suture would be beneficial. Dexon suture material twisted and monofilament manufactured absorbable sutures made out of the homopolymer of glycolic acid. 58-7). uses two polyglycolic acid sutures tied together at the tails, run in opposite directions in a running fashion.44 This is the most common technique, though there is significant variation in the type of suture used as well as the method of attaching the tails. After transtrigonal/cephalotrigonal bilateral ureteral reimplantation, a strip of bladder mucosa 1.5 to 1.8 cm wide and 3.0 to 4.0 cm long is generated and the lateral bladder triangles are demucosalized. PGA and PLA are the most widely used synthetic, biodegradable polymers. This combination was introduced as the LactoSorb craniofacial plate fixation system in 1996. 147.1X). This technique provided 270-degree urethral compression and has generally been effective in female patients; however, it has not been as reliable in male patients. Use of Vicryl (polyglactin 910) sutures in general surgical and cardiothoracic procedures The satisfactory substitute for catgut suture, Vicryl (polyglactin 910) suture, was used in fifty-three patients who underwent general and thoracic surgical procedures. As with any BNR procedure (without augmentation), several months of adjustment will be required before the patient develops adequate bladder awareness, capacity, and control to achieve prolonged intervals of urinary continence. Bertil E. Damato, ... Wallace S. Foulds, in Retina (Fifth Edition), 2013. Polyglycolic acid sutures are composed of polymers made from 100% homopolymer of glycolide. Major skin loss to the penis and scrotum occurs from avulsion injuries, burns, gunshot wounds, and stab wounds. The muscles are resutured to their original insertions with 5–0 braided polyglycolic acid sutures (Fig. A bladder readjustment period may span several months before day and, subsequently night, continence is achieved. Petcryl PGA suture meet all the requirements established by the United States Pharmacopoeia (USP) and the European Pharmacopoeia (EP) for Synthetic Absorbable Surgical Sutures. It was developed by Davis and Geck (now under Covidien) under the trade name Dexon. Cystoscopy and gravity cystography provide information regarding bladder capacity and the status of any previous repairs. The modified Young-Dees-Leadbetter (YDL) BNR technique89 and the transtrigonal/cephalotrigonal bilateral ureteral reimplantation88 are the surgical techniques employed in MSRE stage 3. ( Polyglycolic Acid Suture ) When Predictable Absorption Means Assured Recovery - Ensures minimum tissue reaction due to predictable absorption through hydrolysis Ensures smooth passage through the tissues and enhances firm and safe knotting due to the coating of Polycaprolactone and Calcium Sterate Polyglycolic acid suture with Excellent rigidity over the basic injury for fast twisted mending process uniform distance. It has been processed as a material for sutures (Dexon®). Polyglycolic acid (PGA). The entire procedure usually takes between 2 and 3 hours. The fibers are stretched to several hundred percent of their original length at a temperature above its glass transition temperature (about 36 °C), heat-set to improve dimensional stability and inhibit shrinkage, and subsequently braided into final multifilament braid suture forms of various sizes. Pure PGA was first marketed as Dexon suture; Vicryl suture is a mix of 8% PLA and 92% PGA. Because PGA sutures are absorbed by hydrolysis breakdown, they are not affected by a low pH. 58-5A and B). described the use of a suprapubic tube for postoperative drainage and early removal of the urethral catheter. The urethra is calibrated with a soft 8-Fr catheter, and voiding trials are begun with the suprapubic tube in place after the urine has been sterilized. 3. Polyglycolic Acid, better known as PGA, is composed of polymers of glycolide acids PGA surgical suture is coated to allow for easier passage through tissues with only minimal drag. Krane et al. This reinforces the neobladder neck, decreases the risk of fistula, and augments the outlet resistance.90 The sutures in the third layer are not cut because they are used in the MMK bladder neck suspension.87. Dexon®^-**"^" (polyglycolic acid) represents another of the modern absorbable sutures. Copyright © 2020 Elsevier B.V. or its licensors or contributors. (There are cases where NEOVEIL is torn or damaged) (2) Do not apply to infected regions. Polyglycolic acid is a high molecular, linear copolymer of glycolic acid. It also moves fibrotic tissue at the level of the original bladder neck away from the new bladder neck. Polyglycolic Acid Suture is a synthetic, absorbable, sterile, surgical suture composed of 100% glycolide, coated with polycaprolactone and calcium stearate. Urinary drainage is achieved by the use of bilateral ureteral catheters and suprapubic tube drainage. Postoperatively, whether to leave an indwelling urethral catheter is optional; if so, an 8F pediatric feeding tube seems optimal. C.C. The absorption time for Polyglycolic Acid (PGA) is 60 to 90 days. Voiding trials are performed with measurement of postvoid residual urine volumes to assess for urinary retention before removing the suprapubic tube. Again, if VPI is encountered postoperatively, the suture line may be taken down and the palate may be either re-sutured in a less aggressive position, or may be dealt with again later, once it has remucosalized. If the wound seems severely contaminated, testicles can be placed in subcutaneous pouches on the medial aspect of the thigh. The neourethra is tubularized over an 8-Fr stent using interrupted or running. The original description by Van Velthoven et al. ADVANTAGES AND BENEFITS - Packaging ensures product sterility. Next, the distance around the bladder neck is measured with umbilical tape (see Fig 58-4H). It is well known that postoperative adhesions Polyglycolic Acid Suture is not indicated for cardiovascular and neurological tissue approximation. Polyglycolic acid; CAS Number: 26009-03-0; Synonym: PGA, Poly(2-hydroxyacetic acid); find Sigma-Aldrich-46746 MSDS, related peer-reviewed papers, technical documents, similar products & … "Because of the wide distribution of your journal, I think it is important to set the record straight. a molecule that is not superimposable on its mirror image), it exists in two stereoisomeric forms that give rise to four morphologically different polymers: d-PLA, l-PLA, Dl-PLA and meso-PLA. It is a synthetic adsorbable suture material. The suprapubic tube remains for 3 weeks. PGA can be polymerized either directly or indirectly from glycolic acid. In addition to wound dehiscence, minor bleeding can be encountered, particularly when combined with a tonsillectomy. Many patients with a neuropathic bladder undergoing sling placement ambulate in a wheelchair. uses two, Plastic Surgery Secrets Plus (Second Edition), BLADDER OUTLET SURGERY FOR CONGENITAL INCONTINENCE, G). Dexon suture absorption time The advantage of using suture mainly, it causes less tissue damage. In general, polyglycolic acid sutures are preferable to PCG or CCG for urologic surgery, except in cases of infected urine and for the skin. Before packaging, all Dexon sutures are subjected to heat under vacuum to remove residual unreacted monomers or very low molecular weight volatile oligomers (Casey and Lewis, 1986; Glick and McPherson, 1967). This catheter should be latex-free, and either a Silastic balloon catheter or a Jackson-Pratt drain may be left in the bladder for continuous urinary drainage. Nevertheless, the use of this technique in a patient with an excessively thick palate or uvula might be inadvisable if the resultant thickness might be considered problematic. The fascial or SIS graft is obtained. 3. material used in closing a wound with stitches. The mechanism of polymerization is believed to be cationic melt polymerization if stannous chloride dihydrate (in the presence of alcohol) is used, or nucleophilic attack of a carbanion on one of the glycolide carbonyls if the trialkyl aluminum is used. Polyglycolic acid suture material is a high molecular weight, linear homo-polymerof glycolicacid (hydroxyacet-ic acid) which is extruded into thin filaments and braided into sutures of various diameters in much the same manner as other syntheticfibers, such as Dacron. To the Editor.— In The Journal's medical news (213:381, 1970) an article is entitled "PGA used to make absorbable suture. The most important principle is the creation of a tension-free, watertight anastomosis through mucosa-to-mucosa apposition. It is a synthetic adsorbable suture material. Frequently, an alcohol like lauryl alcohol is added into the polymerization to control the molecular weight. The following section describes the most commonly employed BNR techniques, including the modified Young-Dees-Leadbetter and the Mitchell repairs. The original description by Van Velthoven et al. It can be prepared starting from glycolic acid by means of polycondensation or ring-opening polymerization. 2. A highly concise review is presented of the experimental and clinical literature concerning polyglycolic acid suture material, marketed for clinical use for the first time in 1970. PGA for sutures is polymerized from the cyclic dimer of α-hydroxyacetic acid, more commonly called glycolic acid. Blunt trauma to the scrotum may result in large hematoceles and testicular rupture. Surgical correction of the ruptured testicle should be done by a trans-scrotal approach with evacuation of the hematoma and repair of the injury. PGA’s remarkable characteristics are out-standing tensile strength, predictable absorption time, This suture material will maintain sufficient tension over the first 2 weeks (75%), 50% after 3 weeks, and 25% after 2 weeks.40 PGA sutures have varying resorption rates, which consist of regular breakdown (≈21–28 days) and fast absorbing (≈7–14 days). It has excellent mechanical properties and is rapidly degraded into lactic acid. - Peel open. The suture material is inert and has a relatively low tissue reaction. 44 This is the most common technique, though there is significant variation in the type of suture used as well as the method of attaching the tails. PGA surgical suture is coated to allow for easier passage through tissues with only minimal drag. - Absorbable suture (poliglicolic acid). The urethral edges are reapproximated with interrupted 2-0, Current Therapy of Trauma and Surgical Critical Care, Michael Mitchell MD, Richard Grady MD, in, Ashcraft's Pediatric Surgery (Fifth Edition), the bladder neck is extensively dissected and a vertical cystotomy is made. At 2 to 3 weeks postoperatively, urethral catheterization with a coudé catheter is recommended if the patient is to perform urethral CIC (Fig. The limitation of these sutures is that they tend to lose their mechanical properties over a period of 2–4 weeks after implantation.
