The neourethra is tubularized over an 8-Fr stent using interrupted or running polyglycolic acid sutures (4-0 or 5-0). Polyglycolic Acid, better known as PGA, is composed of polymers of glycolide acids. In general, polyglycolic acid sutures are preferable to PCG or CCG for urologic surgery, except in cases of infected urine and for the skin. Rare complications can include wound separation, which can be minimized by avoiding chromic sutures that may resorb prematurely and by closing the incisions in two layers.

To the Editor.— In The Journal's medical news (213:381, 1970) an article is entitled "PGA used to make absorbable suture. 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. 58-7). 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. Immediate detumescence occurs, and a hematoma develops on the penile shaft. 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. 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 Jack S. Elder, Joao Luiz Pippi Salle, in Pediatric Urology, 2010. Patients treated promptly in this manner almost always have a return of normal sexual function. PGA suture are available in dyed (violet colour suture) and also un-dyed versions from USP sizes 6-0 to USP size 2. The crisscrossing can cause variable circumferential compression, however, and the urethra can sometimes be difficult to catheterize. Polyglycolic Acid. 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). Urinary drainage is achieved by the use of bilateral ureteral catheters and suprapubic tube drainage. Urethrography should be done to determine whether concomitant urethral injury is present. PGA’s remarkable characteristics are out-standing tensile strength, predictable absorption time, 3-0 poliglecaprone (Monocryl®, Ethicon, Somerville, NJ) sutures with an RB needle to create a double-armed suture, and perform the anastomosis very similar to Van Velhoven’s technique. 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. Voiding trials are performed with measurement of postvoid residual urine volumes to assess for urinary retention before removing the suprapubic tube. ! Use of an epinephrine-soaked sponge during this dissection aids in hemostasis and visualization. ORYL (Polyglycolic Acid) is an ideal and time tested synthetic absorbable suture, widely used by surgeons. There are a variety of Dexon sutures. The tension necessary for urethral closure can be tested by manually compressing the bladder to observe for urethral leakage. Dexon suture fibers are made by the melt spinning of PGA chips. PGA surgical suture is coated to allow for easier passage through tissues with only minimal drag. PGA implants lose their tensile strength quickly and are resorbed within weeks to months. 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. Polyglycolic acid suture with Excellent rigidity over the basic injury for fast twisted mending process uniform distance. The anastomosis is then tested by filling the bladder with 300 cm3 of saline and observing for any possible leaks. Dexon suture absorption time The advantage of using suture mainly, it causes less tissue damage. Polyglycolic acid sutures are composed of polymers made from 100% homopolymer of glycolide. uses two, Plastic Surgery Secrets Plus (Second Edition), BLADDER OUTLET SURGERY FOR CONGENITAL INCONTINENCE, G). 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. It is a synthetic adsorbable suture material. Ureteral stents are removed at 2 to 3 weeks, and voiding trials are begun in the third week. There are several general techniques for sling placement. It can be prepared starting from glycolic acid by means of polycondensation or ring-opening polymerization. Vicryl, being a Polyglactin material is made from made from copolymer of 90% Glycolide and 10% L-lactide but Petcryl suture are 100% glycolide. Polyglycolic Acid Suture is indicated for use in general soft tissue approximation and/or … The original description by Van Velthoven et al. PGA is the simplest linear polyester. Jon B. Suzuki, Randolph R. Resnik, in Misch's Avoiding Complications in Oral Implantology, 2018. 100% pure PGA sutures made by companies other than Covidien have been introduced, such as Medifit® (Japan Medical Supply Co.) Safil and Safil Quick (B. Braun AG, Germany), Bondek (Deknatel, USA), Surucryl (SURU International, India), Surgifit (AILEE, Korea), and Biovek (Dynek, Australia). 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). CARESYN® RAPID – Polyglycolic Acid (fast absorbing) Surgical Sutures are indicated for use in superficial soft tissue approximation of the skin and mucosa, where only short-term wound support (7-10 days) is required, but not for use in ligation, ophthalmic, cardiovascular, or neurological procedures. Two common uses include the renorrhaphy closure in partial nephrectomy and the vesicourethral anastomosis in radical prostatectomy. Return of spermatogenesis after such an injury is unpredictable. 2. Bladder neck tapering is achieved by excising a wedge from each side of the bladder neck and proximal urethra (see Fig 58-4G). Bertil E. Damato, ... Wallace S. Foulds, in Retina (Fifth Edition), 2013. The limitation of these sutures is that they tend to lose their mechanical properties over a period of 2–4 weeks after implantation. PGA can be polymerized either directly or indirectly from glycolic acid. The bladder may be closed in continuity with the urethral closure. 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. 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. A bladder capacity less than 60 mL under anesthesia or during urodynamic evaluation decreases the success of BNR. Distinctive Characteristics of PGA Suture: – Read more about pga sutures manufactured by Dolphin Sutures. A chondrocyte-seeded PLA/PGA polymer similar to Vicryl has been used in the “tissue engineering” of cartilage scaffolding. Dexon Plus is coated with a copolymer of poly(oxyethylene-oxypropylene), while Dexon II has a polycaprolate coating. In addition, regular urine cultures and, if enterocystoplasty has been performed, serum electrolyte determinations should be performed. In our opinion, the most effective method for sling placement takes advantage of the bladder neck–tapering techniques described by Herschorn and Radomski73 and by Walker and colleagues74 in conjunction with circumferential sling placement (see Fig. ScienceDirect ® is a registered trademark of Elsevier B.V.

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. They include organometallic compounds and Lewis acids. It has excellent mechanical properties and is rapidly degraded into lactic acid. 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). Sculptra is a newly developed PLA product for midfacial soft tissue augmentation due to the wasting caused by protease inhibitors. By continuing you agree to the use of cookies. PGA suture retain approximately 75% of PGA initial strength after two weeks. Petcryl PGA suture meet all the requirements established by the United States Pharmacopoeia (USP) and the European Pharmacopoeia (EP) for Synthetic Absorbable Surgical Sutures. Polyglycolide or poly, also spelled as polyglycolic acid, is a biodegradable, thermoplastic polymer and the simplest linear, aliphatic polyester. Some surgeons recommend avoidance of a urethral catheter in the postoperative period because of concerns that it may adversely affect later urinary continence. This procedure effectively narrows and lengthens the urethra. The urethral catheter is removed 7 to 10 days after the operation. A vertical cystotomy is made through the anterior bladder neck. of the suture material used, and (4) polyglactic acid suture material may be preferable to polyglycolic acid suture material for infertility surgery, in which a minimum of tissue reaction is imperative. Polyglycolic acid (PGA). The use of a 2–0 or 3–0 polyglycolic acid suture, as noted before, is recommended. 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. The combined thoughts of several surgeons spanning an 82-year period have led to the modern YDL BNR.87 To perform a modified YDL procedure,89 the bladder neck is extensively dissected and a vertical cystotomy is made. Lactic acid is a chiral molecule (i.e. 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. 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. If no urine is passed, cystoscopy and urethral stenting may be required for a short period of time. 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. Penile fracture, although uncommon, demands immediate diagnosis and correction. Next, the distance around the bladder neck is measured with umbilical tape (see Fig 58-4H). These individuals often prefer a Mitrofanoff catheterizable abdominal stoma to urethral catheterization. Polyglycolic Acid Suture is not indicated for cardiovascular and neurological tissue approximation. 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. Polyglycolic Acid Suture is a synthetic, absorbable, sterile, surgical suture composed of 100% glycolide, coated with polycaprolactone and calcium stearate. However, the urethra of these patients may be difficult to catheterize. Michael Mitchell MD, Richard Grady MD, in Ashcraft's Pediatric Surgery (Fifth Edition), 2010. The crystalline properties differ from polymer to polymer. The muscles are resutured to their original insertions with 5–0 braided polyglycolic acid sutures (Fig. 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. 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 & … The success rate of the sling has varied among many different centers and techniques, but is comparable or superior to all of the other techniques that have been described for the surgical management of insufficient outlet resistance (Table 58-1).75 Postoperatively, patients should undergo regular upper tract imaging with a renal ultrasound scan or noncontrast CT scan. The introduction of the more hydrophobic PLA into the polymeric structure limits the water uptake and reduces the rate of backbone hydrolysis. 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. MATEOS-TIMONEDA, in Bone Repair Biomaterials, 2009. This repair employs a modification of the Leadbetter procedure technique described previously.89 In this modification, a full-thickness transverse incision is made in the anterior urethra and is extended cephalad. The Polyglycolic Acid surgical suture is indicated for use in in general surgery, plastic surgery, ophthalmic surgery, gynecology and obstetrics, episiotomy, urology, orthopedics, gastroenterology, general closure, ligatures, pediatrics and cuticular. PGA is a commonly used suture material and was the first material used to construct nerve conduits when the limitations of silicone tubes were observed. Surgical correction of the ruptured testicle should be done by a trans-scrotal approach with evacuation of the hematoma and repair of the injury. Polyglycolic acid sutures are coated with equal parts of Polycaprolactone and Calcium stearate less than 5% w/w. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Many patients with a neuropathic bladder undergoing sling placement ambulate in a wheelchair. 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. China Polyglycolic Acid (PGA) Surgical Suture with CE, Find details about China Polyglycolic Acid Suture, Absorbable Sutures from Polyglycolic Acid (PGA) Surgical Suture with CE - … Osteotomies may also be necessary to stabilize the intersymphyseal bar and improve continence at the time of BNR. The following section describes the most commonly employed BNR techniques, including the modified Young-Dees-Leadbetter and the Mitchell repairs. The most important principle is the creation of a tension-free, watertight anastomosis through mucosa-to-mucosa apposition. Occasionally, a portion of the intersymphyseal band must be divided completely for good visualization. This has diminished the necessity of the thigh pouch technique, and delayed reconstruction. 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. The entire procedure usually takes between 2 and 3 hours. Management should be aimed at reconstruction, using all attached salvageable skin. A transverse tear in the tunica albuginea that surrounds the erectile bodies occurs as a result of the force applied to the area. Krane et al. 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. Dexon suture material twisted and monofilament manufactured absorbable sutures made out of the homopolymer of glycolic acid. It also moves fibrotic tissue at the level of the original bladder neck away from the new bladder neck. Postoperatively, whether to leave an indwelling urethral catheter is optional; if so, an 8F pediatric feeding tube seems optimal. M.A. Ureteral stents are removed at 10 to 14 days after surgery. Numerous catalysts are available for this ring opening polymerization. 58-5D). A suprapubic catheter is left indwelling for 2 to 3 weeks before catheterization is initiated. 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. After cross-trigonal ureteral reimplantation, the urethral strip is tubularized in two layers using polyglycolate or monocryl suture (4-0 or 5-0) over an 8- or 10-Fr urethral catheter depending on the size of the patient. When local skin is not available, split-thickness skin grafts can be used to cover the testicles and penis. (There are cases where NEOVEIL is torn or damaged) (2) Do not apply to infected regions. 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. 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. 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. Approximately 45% of the PGA suture’s original tensile strength remains. 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. 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. It is a synthetic, completely absorbable, non-toxic product, which not only offers a number of advantages over catgut, but may also be used where non-absorbable materials were formerly applied exclusively. The conjunctiva is closed with 8–0 braided polyglactin sutures (Fig. - Siliconized needles allowing a minimum tissue trauma. 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. It is highly crystalline and consequently it presents a high melting point and low solubility in organic solvents. The suture ends are crisscrossed anterior to the urethra, providing 360-degree urethral compression by the graft (Fig. - Peel open. UNIGLYDE Polyglycolic Acid Suture meets all the requirements as per United States Pharmacopeia for Absorbable Surgical suture (Synthetic) Indications Polyglycolic Acid (PGA Suture) suture is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures, but not for use in cardiovascular or neurological tissues. Consequently, fixation of the graft to the bladder neck in two to three places with 4-0 polyglycolic acid sutures is helpful (see Fig. They reported less pain compared to traditional urethral catheterization.46, Stephen Daane MD, in Plastic Surgery Secrets Plus (Second Edition), 2010. A free needle is placed on each of the four suture ends, and they are advanced through the abdominal fascia lateral to the rectus muscle. Polyglycolic acid sutures absorb by simple hydrolytic mechanism and absorption is predictable. Monofilament synthetic absorbable suture, prepared from the polyester, poly (p-dioxanone). The need for complete orchiectomy is not often necessary when injury results from blunt trauma, particularly if diagnosed within 48 hours of injury. 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). 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. Third-degree burns of the penile shaft and scrotum should be corrected with total skin excision and immediate replacement with split-thickness skin grafts. These testicles heal after reconstruction and are useful for hormone production and cosmetic appearance. The absorption time for Polyglycolic Acid (PGA) is 60 to 90 days. "Because of the wide distribution of your journal, I think it is important to set the record straight. Various types of sutures. Braided synthetic adsorbable multifilament made of polyglycolic acid and coated with N-laurin and L-lysine, which render the thread extremely smooth, soft and knot safe. described the use of a suprapubic tube for postoperative drainage and early removal of the urethral catheter. Major skin loss to the penis and scrotum occurs from avulsion injuries, burns, gunshot wounds, and stab wounds. 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. 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 has been known since 1954 as a tough fiber-forming polymer. The resulting PGA polymer having Mw from 20 000 to 140 000 is suitable for fiber extrusion and suture manufacturing. 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. 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. As originally described, the sling was placed around the urethra and suspended up against the pubic symphysis in a “U” shape (Fig. Metallic fixation interferes with postoperative radiographic imaging, oncologic follow-up, and evaluation of fracture healing. The original description by Van Velthoven et al. - 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 PGA is an ideal and time tested synthetic absorbable suture, widely used by surgeons all over the world. Due to its absorption profile Coated Polyglycolic acid (PGA). As the sling tension is increased, the surgeon should ascertain that urethral catheterization can be accomplished. 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.
