polyglycolic acid suture uses

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 - … Because PGA sutures are absorbed by hydrolysis breakdown, they are not affected by a low pH. 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. Polyglycolic acid sutures are composed of polymers made from 100% homopolymer of glycolide. Use of an epinephrine-soaked sponge during this dissection aids in hemostasis and visualization. The entire procedure usually takes between 2 and 3 hours. Pure PGA was first marketed as Dexon suture; Vicryl suture is a mix of 8% PLA and 92% PGA. For biomedical applications, stannous chloride dihydrate or trialkyl aluminum are preferred. - Siliconized needles allowing a minimum tissue trauma. CARESYN® Polyglycolic Acid Surgical Sutures (PGA sutures) are 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. When traction is placed on each end of the sling, the graft has a tendency to curl or roll up. 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. Tension may be adjusted to provide optimal urethral compression. The original description by Van Velthoven et al. The need for complete orchiectomy is not often necessary when injury results from blunt trauma, particularly if diagnosed within 48 hours of injury. They reported less pain compared to traditional urethral catheterization.46, Stephen Daane MD, in Plastic Surgery Secrets Plus (Second Edition), 2010. Polyglycolic acid sutures absorb by simple hydrolytic mechanism and absorption is predictable. If no urine is passed, cystoscopy and urethral stenting may be required for a short period of time. We use cookies to help provide and enhance our service and tailor content and ads. The bladder neck may be funneled further with small vertical incisions along the cut edge of the lateral bladder walls. PGA is the simplest linear polyester. In such cases, the sling tension may be increased slightly to maximize the likelihood of having a continent reconstructed sphincter. It is a synthetic adsorbable suture material. Jon B. Suzuki, Randolph R. Resnik, in Misch's Avoiding Complications in Oral Implantology, 2018. PGA suture are available in dyed (violet colour suture) and also un-dyed versions from USP sizes 6-0 to USP size 2. 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. The absorption time for Polyglycolic Acid (PGA) is 60 to 90 days. The original description by Van Velthoven et al. 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. A suprapubic catheter is left indwelling for 2 to 3 weeks before catheterization is initiated. PGA and PLA are the most widely used synthetic, biodegradable polymers. M.A. 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. 2. a stitch or series of stitches made to secure apposition of the edges of a surgical or traumatic wound; used also as a verb to indicate application of such 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. 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. We use two 6-in. Advocates of staged reconstruction emphasize the importance of achieving adequate bladder capacity before performing BNR. Polyglycolic Acid Suture is indicated for use in general soft tissue approximation and/or … The width of the graft should be approximately 2 cm, and the graft length should be 3 to 5 mm less than the urethral circumference. 3. The following section describes the most commonly employed BNR techniques, including the modified Young-Dees-Leadbetter and the Mitchell repairs. PGA for sutures is polymerized from the cyclic dimer of α-hydroxyacetic acid, more commonly called glycolic acid. It is highly crystalline and consequently it presents a high melting point and low solubility in organic solvents. ORYL (Polyglycolic Acid) is an ideal and time tested synthetic absorbable suture, widely used by surgeons. 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. The anastomosis is then tested by filling the bladder with 300 cm3 of saline and observing for any possible leaks. Two common uses include the renorrhaphy closure in partial nephrectomy and the vesicourethral anastomosis in radical prostatectomy. 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. Experimentation with absorbable polyesters led to the development of poly-l-lactic acid (PLA) and polyglycolic acid (PGA) as resorbable implantable devices. ADVANTAGES AND BENEFITS - Packaging ensures product sterility. At 2 to 3 weeks postoperatively, urethral catheterization with a coudé catheter is recommended if the patient is to perform urethral CIC (Fig. (A mild inflammatory reaction may occur, which is typical of an endogenous reaction to foreign bodies) 58-5A and B). 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. sutures maintain strength for the four to six-week period of collagen formation in the healing process. PGA's superior features over catgut are predictable absorption, outstanding tensile strength, invivo inertness and excellent handling properties. Absorption of bio-absorbable suture occurs by hydrolysis ; beginning with loss of tensile strength followed by loss of mass. - Absorbable suture (poliglicolic acid). 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. Return of spermatogenesis after such an injury is unpredictable. 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. The suture material is inert and has a relatively low tissue reaction. Polyglycolic Acid Suture is not indicated for cardiovascular and neurological tissue approximation. As the sling tension is increased, the surgeon should ascertain that urethral catheterization can be accomplished. A chondrocyte-seeded PLA/PGA polymer similar to Vicryl has been used in the “tissue engineering” of cartilage scaffolding. Cystoscopy and gravity cystography provide information regarding bladder capacity and the status of any previous repairs. PGA has orthorhombic unit cell with dimensions a = 5.22 Å, b = 6.19 Å, and c (fiber axis) = 7.02 Å. Blunt trauma to the scrotum may result in large hematoceles and testicular rupture. 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). These testicles heal after reconstruction and are useful for hormone production and cosmetic appearance. Proper mucosa-to-mucosa apposition will lead to improved continence, low leak rates, and reliable prevention of bladder neck contracture.45, We typically leave a new 20-French two-way Foley catheter with 20 cm3 in the balloon as our final catheter. It has been processed as a material for sutures (Dexon®). 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. The bladder may be closed in continuity with the urethral closure. 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 Sculptra is a newly developed PLA product for midfacial soft tissue augmentation due to the wasting caused by protease inhibitors. 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. 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 (PGA). Both d and l polymers are semicrystalline materials, whereas the optically inactive dL-PLA is always amorphous. Frequently, an alcohol like lauryl alcohol is added into the polymerization to control the molecular weight. 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. Owing to its hydrolytic instability, however, its use has initially been limited. 58-6B and C). PGA’s superior features over catgut are predictable absorption, outstanding tensile strength, in-vivo inertness and excellent handling properties. 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. Third-degree burns of the penile shaft and scrotum should be corrected with total skin excision and immediate replacement with split-thickness skin grafts. Postoperatively, urine is drained through a combination of ureteral stents, a suprapubic tube, and a 6-Fr urethral catheter. 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. A vertical cystotomy is made through the anterior bladder neck. 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. 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. If augmentation is required, appendicovesicostomy or another form of the Mitrofanoff operation can be simultaneously performed if the urethra is difficult to negotiate because of the likelihood that the patient will require intermittent catheterization to empty the bladder after BNR. Ureteroneocystostomy may be required at the time of BNR to correct VUR and to move the ureters from the lower bladder where BNR will occur. Ureteral stents are removed at 2 to 3 weeks, and voiding trials are begun in the third week. Charles D. Best, in Current Therapy of Trauma and Surgical Critical Care, 2008. The suprapubic tube remains for 3 weeks. 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. Placement of the periurethral sling generally is done at the end of the reconstructive procedure because the tension on the sling can be adjusted, and one can test the strength of the sling after the bladder is closed. After the closure, dissection around the new bladder neck may be performed if a combined bladder neck wrap or sling will also be created. Approximately 45% of the PGA suture’s original tensile strength remains. The introduction of the more hydrophobic PLA into the polymeric structure limits the water uptake and reduces the rate of backbone hydrolysis. 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. The neourethra is tubularized over an 8-Fr stent using interrupted or running polyglycolic acid sutures (4-0 or 5-0). The bladder neck may be funneled further with small vertical incisions along the cut edge of the lateral bladder walls. The most important principle is the creation of a tension-free, watertight anastomosis through mucosa-to-mucosa apposition. Voiding trials are performed with measurement of postvoid residual urine volumes to assess for urinary retention before removing the suprapubic tube. The muscles are resutured to their original insertions with 5–0 braided polyglycolic acid sutures (Fig. Patients treated promptly in this manner almost always have a return of normal sexual function. There are several general techniques for sling placement. Due to its absorption profile Coated Polyglycolic acid (PGA). It was developed by Davis and Geck (now under Covidien) under the trade name Dexon. Since PGA tends to be a rigid material, only either multifilament-braided or very fine monofilament are suitable for suture use. MATEOS-TIMONEDA, in Bone Repair Biomaterials, 2009. Dexon suture absorption time The advantage of using suture mainly, it causes less tissue damage. 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 & … 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. Krane et al. PGA has been known since 1954 as a tough fiber-forming polymer. Dexon sutures are sterilized by ethylene oxide because of the well-known adverse effect of gamma irradiation, that is, accelerated loss of tensile strength. Metallic fixation interferes with postoperative radiographic imaging, oncologic follow-up, and evaluation of fracture healing. 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 is a high molecular, linear copolymer of glycolic acid. 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. This is often described as an “eggplant” deformity. 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 this reason, l-PLA is preferred for application where high mechanical strength and toughness are needed. There are a variety of Dexon sutures. A transverse tear in the tunica albuginea that surrounds the erectile bodies occurs as a result of the force applied to the area. BNR requires adequate bladder capacity because some volume is lost during the procedure. - Braided suture, monofilament.- Coated with polycaprolactone and calcium sterate - The absorption of this suture is complete within 70 days being absorbed by hydrolysis. Chu, in Biotextiles as Medical Implants, 2013. All over the world. With the bladder open, the bladder neck is mobilized using the Lottmann technique. The limitation of these sutures is that they tend to lose their mechanical properties over a period of 2–4 weeks after implantation. This procedure effectively narrows and lengthens the urethra. The crisscrossing can cause variable circumferential compression, however, and the urethra can sometimes be difficult to catheterize. It is well known that postoperative adhesions This combination was introduced as the LactoSorb craniofacial plate fixation system in 1996. As originally described, the sling was placed around the urethra and suspended up against the pubic symphysis in a “U” shape (Fig. 58-5C). A copolymer of PLA (82%) and PGA (18%) was developed that consistently demonstrated adequate initial strength and complete resorption after 9 to 15 months. Monofilament synthetic absorbable suture, prepared from the polyester, poly (p-dioxanone). 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. 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. 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). 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. Petcryl PGA suture meet all the requirements established by the United States Pharmacopoeia (USP) and the European Pharmacopoeia (EP) for Synthetic Absorbable Surgical Sutures. 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 urethral catheter is removed 7 to 10 days after the operation. With these methods, acceptable cosmetic and functional results can be expected. Bladder neck tapering is achieved by excising a wedge from each side of the bladder neck and proximal urethra (see Fig 58-4G). Polyglycolide or poly, also spelled as polyglycolic acid, is a biodegradable, thermoplastic polymer and the simplest linear, aliphatic polyester. Use of an epinephrine-soaked sponge during this dissection aids in hemostasis and visualization. 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. Vicryl, being a Polyglactin material is made from made from copolymer of 90% Glycolide and 10% L-lactide but Petcryl suture are 100% glycolide. 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. described the use of a suprapubic tube for postoperative drainage and early removal of the urethral catheter. 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. PGA suture are indicated for use in general soft tissue approximation including ophthalmic surgery. 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). The neourethra is tubularized over an 8-Fr stent using interrupted or running. Occasionally, a portion of the intersymphyseal band must be divided completely for good visualization. More recently, some workers have advocated crisscrossing the sling to provide 360-degree urethral compression (see Fig. Dexon suture fibers are made by the melt spinning of PGA chips. Polyglycolic acid sutures are coated with equal parts of Polycaprolactone and Calcium stearate less than 5% w/w. The original description by Van Velthoven et al. What are the different types of Sutures? PGA’s remarkable characteristics are out-standing tensile strength, predictable absorption time, ( 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 Major skin loss to the penis and scrotum occurs from avulsion injuries, burns, gunshot wounds, and stab wounds. The suture ends are crisscrossed anterior to the urethra, providing 360-degree urethral compression by the graft (Fig. For PGA of suture fiber grade (i.e., molecular weight > 20 000), ring-opening polymerization of the cyclic dimers of glycolic acid is used. 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. The use of a 2–0 or 3–0 polyglycolic acid suture, as noted before, is recommended. 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 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. Postoperatively, whether to leave an indwelling urethral catheter is optional; if so, an 8F pediatric feeding tube seems optimal. The resulting PGA polymer having Mw from 20 000 to 140 000 is suitable for fiber extrusion and suture manufacturing. 2. polyglycolic acid: [ soo´chur ] 1. sutura . PGA implants lose their tensile strength quickly and are resorbed within weeks to months. The heat of fusion of 100% crystallized PGA is reported to be 12 KJ/mol (45.7 cal/g). In addition, regular urine cultures and, if enterocystoplasty has been performed, serum electrolyte determinations should be performed. Numerous catalysts are available for this ring opening polymerization. Penile fracture, although uncommon, demands immediate diagnosis and correction. Polyglycolic Acid. PGA can be polymerized either directly or indirectly from glycolic acid. 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. Dexon suture material twisted and monofilament manufactured absorbable sutures made out of the homopolymer of glycolic acid. However, the urethra of these patients may be difficult to catheterize. Tod C. Huntley, in Sleep Apnea and Snoring, 2009. 3. material used in closing a wound with stitches. PGA surgical suture is coated to allow for easier passage through tissues with only minimal drag. Occasionally, a portion of the intersymphyseal band must be divided completely for good visualization. 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. They include organometallic compounds and Lewis acids. Polyglycolic Acid Suture is a synthetic, absorbable, sterile, surgical suture composed of 100% glycolide, coated with polycaprolactone and calcium stearate. "Because of the wide distribution of your journal, I think it is important to set the record straight. Table 2.1 summarizes the characteristics of several sutures. Polyglycolic Acid, better known as PGA, is composed of polymers of glycolide acids. It has excellent mechanical properties and is rapidly degraded into lactic acid. Bertil E. Damato, ... Wallace S. Foulds, in Retina (Fifth Edition), 2013. The two suture ends from each side are tied together anterior to the rectus fascia with a surgeon’s knot. Currently polyglycolide and its copolymers are widely used as a material for the synthesis of absorb 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. It is necessary to place much more tension around the male urethra than the female urethra to achieve continence (see Fig. 2. Dexon®^-**"^" (polyglycolic acid) represents another of the modern absorbable sutures. Management should be aimed at reconstruction, using all attached salvageable skin. 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). In addition to wound dehiscence, minor bleeding can be encountered, particularly when combined with a tonsillectomy. 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. 58-4I). It is extruded into thin filaments and braided into sutures in 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. These individuals often prefer a Mitrofanoff catheterizable abdominal stoma to urethral catheterization. A bladder capacity less than 60 mL under anesthesia or during urodynamic evaluation decreases the success of BNR. Some surgeons recommend avoidance of a urethral catheter in the postoperative period because of concerns that it may adversely affect later urinary continence. Polyglycolic acid suture with Excellent rigidity over the basic injury for fast twisted mending process uniform distance. The two triangular regions of demucosalized detrusor muscle are then closed over the mucosal tube in a two-layer “vest over pants” double-breasted technique using 3-0 polyglycolic acid sutures. By continuing you agree to the use of cookies. 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. In general, polyglycolic acid sutures are preferable to PCG or CCG for urologic surgery, except in cases of infected urine and for the skin. 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. 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. Consequently, fixation of the graft to the bladder neck in two to three places with 4-0 polyglycolic acid sutures is helpful (see Fig. ! 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. When local skin is not available, split-thickness skin grafts can be used to cover the testicles and penis.
