Mattress Sutures (mattress + suture)
Selected AbstractsFrequency of Use of Suturing and Repair Techniques Preferred by Dermatologic SurgeonsDERMATOLOGIC SURGERY, Issue 5 2006BETH ADAMS MD BACKGROUND There are many closure techniques and suture types available to cutaneous surgeons. Evidence-based data are not available regarding the frequency of use of these techniques by experienced practitioners. OBJECTIVE To quantify, by anatomic site, the frequency of use of common closure techniques and suture types by cutaneous surgeons. METHOD A prospective survey of the members of the Association of Academic Dermatologic Surgeons that used length-calibrated visual-analog scales to elicit the frequency of use of specific suture techniques. RESULTS A response rate of 60% (61/101) indicated reliability of the received data. Epidermal layers were closed most often, in descending order, by simple interrupted sutures (38,50%), simple running sutures (37,42%), and vertical mattress sutures (3,8%), with subcuticular sutures used more often on the trunk and extremities (28%). The most commonly used superficial sutures were nylon (51%) and polypropylene (44%), and the most common absorbable suture was polyglactin 910 (73%). Bilayered closures, undermining, and electrocoagulation were used, on average, in 90% or more sutured repairs. The median diameters (defined as longest extent along any axis) of most final wound defects were 1.1 to 2.0 cm (56%) or 2.1 to 3.0 cm (37%). Fifty-four percent of wounds were repaired by primary closure, 20% with local flaps, and 10% with skin grafting, with the remaining 15% left to heal by second intent (10%) or referred for repair (5%). Experience-related differences were detected in defect size and closure technique: defects less than 2 cm in diameter were seen by less experienced surgeons, and defects greater than 2 cm by more experienced surgeons (Wilcoxon's rank-sum test: p=.02). But more experienced surgeons were less likely to use bilayered closures (r=,0.28, p=.036) and undermining (r=,0.28, p=.035). CONCLUSIONS There is widespread consensus among cutaneous surgeons regarding optimal suture selection and closure technique by anatomic location. More experienced surgeons tend to repair larger defects but, possibly because of their increased confidence and skill, rely on less complicated repairs. [source] A Method of Augmenting the Cheek Area Through SMAS, subSMAS, and Subcutaneous Tissue Recruitment During Facelift SurgeryDERMATOLOGIC SURGERY, Issue 3 2003Dominic A. Brandy MD BACKGROUND As the human face ages, there is a depletion of fat that occurs in the submalar region. Various techniques such as fat transfers, fillers, alloplastic implants, and composite rhytidectomies have been used to augment this area in the past. OBJECTIVE To describe a technique that augments the submalar areas during facelift surgery without the use of fat transfer, fillers, alloplastic implants, or a risky composite technique. METHOD An oval is scribed over the depressed submalar areas preoperatively. During facelift surgery, a fusiform area is scribed over the SMAS. This fusiform is scribed so that the medial end is directed at the center of the submalar depression, and the lateral end is toward the posterior earlobe. A defect is created within the lateral aspect of the fusiform, but not the medial portion. The fusiform is subsequently closed with a 2-0 Ethibond suture using three horizontal mattress sutures and two interrupted sutures. Upon closure of this defect, SMAS, subSMAS, and subcutaneous tissue overlying the SMAS are recruited into the submalar defect by the simple phenomenon of dog-ear formation. Additionally, there is a component of frank elevation of the tissues inferior to the medial aspect of the fusiform and submalar space. RESULTS The aforementioned technique has been performed on 123 patients over 7 years and has resulted in consistently good improvement in the submalar space. The procedure is not difficult to learn, and good results can be achieved with initial cases. The learning curve was not found to be steep, with good results being achieved quickly. CONCLUSION Depression of the submalar space plays a significant role in creating an aged face. In the past, various fillers and/or alloplastic implants have been used to augment this region. A low-risk method is described that mobilizes SMAS, subSMAS, and subcutaneous tissues into the submalar space through the phenomenon of dog-ear formation after fusiform closure. [source] Facilitating the technique of laparoscopic running urethrovesical anastomosis using Lapra-ty absorbable suture clipsINTERNATIONAL JOURNAL OF UROLOGY, Issue 2 2006YASUMASA SHICHIRI Abstract, We herein describe a simplified technique for performing laparoscopic running urethrovesical anastomosis using Lapra-ty absorbable suture clips (Ethicon, Somerville, NJ, USA) during a laparoscopic radical prostatectomy (LRP). Using two 20 cm absorbable sutures tied together and locked with Lapra-ty at their tail ends, the initiating mattress sutures are placed in the 5:30,6:30-o'clock area between the urethra and the bladder neck. The left and right running sutures are then made clockwise from the 6:30,12-o'clock position and counterclockwise from the 5:30,12-o'clock position, respectively. Both sutures are locked with proper tension by Lapra-ty at the 3, 9 and 12-o'clock positions, and then they are intracorporeally tied together just at the 12-o'clock position. In the initial 20 cases, this anastomosis took 22.5 min on average to perform. We experienced no major urine extravasation and no anastomotic stricture to date. [source] A Technique of Snaring Method for Fitting a Prosthetic Valve into the AnnulusJOURNAL OF CARDIAC SURGERY, Issue 1 2005Shigeo Nagasaka M.D. We modified the previously reported method and designed a simpler tying technique. Patients: We performed 11 aortic (AVR: including four cases for calcified aortic stenosis (AS) with a small annulus and one cases for infective endocarditis with intramuscular abscess cavity), eight mitral valve replacements (MVR), and one tricuspid valve replacement (TVR: for corrected transposition of the great arteries). Techniques and Results: A PV was implanted using 2-0 polyester mattress sutures with a pledget. Each of the two tourniquets held a suture at the bottom of the annulus and at the opposite position to fit a PV. The sutures between each snare were tied down from the bottom to the top. In MVR, after seating of a PV with two tourniquets, we could make sure that no native tissue of any preserved mitral apparatus disturbed PV leaflet motion. In calcific AS, a PV had a good fitting into the annulus because of tourniquets applied to unseated part during tying sutures. In AVR for infective endocarditis, mattress sutures supported by a Teflon pledget were placed to close the abscess cavity. After snaring on one of these sutures, we tied down the sutures, ensuring that they did not cut through the friable tissues. In TVR, we found that native leaflets interfered with PV motion after seating down the prosthesis and those leaflets were resected before tying down the sutures. Postoperative transesophageal echocardiography showed no paravalvular leakage in any patients and excellent PV functions. [source] Laparoscopic-assisted onlay meshplasty to treat umbilical hernias in patients with severe cirrhosisASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 2 2010M Tomikawa Abstract We used laparoscopic-assisted onlay meshplasty to treat umbilical hernias in four patients with severe cirrhosis. A skin incision was made just above the hernia and the circumferential abdominal wall was exposed. Under laparoscopic vision, transabdominal-wall mattress sutures were placed circumferentially around the hernia without leaving a gap between the sutures, and the mesh was placed over the hernia sac and fixed by ligation. Neither postoperative peritonitis nor rupture with ascites was found. None of the patients experienced hernia recurrence or mesh infection after a mean follow-up of 563 d. There was no relevant mortality. Laparoscopic-assisted onlay meshplasty to treat umbilical hernias in patients with severe cirrhosis seems to be technically feasible and offers good results without complications and early recurrence. [source] Dog model for study of supracrestal bone apposition around partially inserted implantsCLINICAL ORAL IMPLANTS RESEARCH, Issue 5 2002Ann-Marie Roos-Jansåker Abstract: A dog model for study of supracrestal bone growth around partially inserted implants is described. The mandibular premolar teeth (P1, P2, P3 and P4) were extracted on both sides of the mandible in four dogs. At a surgical exposure 12 weeks later, two 10 mm titanium implants were partially inserted on each side, 15 mm apart, in the areas of the P1 and the P3 so that five threads protruded from the bone crest. A titanium mesh was fastened to the coronal aspect of the two fixtures and covered with an ePTFE membrane. Thus, a space for potential bone formation was created between the two implants. The surgical flaps were coronally positioned and secured with vertical mattress sutures. After 12 weeks of healing, biopsy specimens were retrieved and examined histologically. In three of the four dogs under study, the partially inserted implants had integrated and the intended large wound spaces had been created around the noninserted parts of the implants. However, bone was not formed around the protruding implants. Accordingly, this experimental model may prove useful for future studies on the use of various procedures that hypothetically may enhance bone formation. [source] | ||||||||||
