BACKGROUND: During repair of tetralogy of Fallot (TOF), when a transannular patch is needed in case of a small annulus and dysplastic pulmonary valve, we chose to reconstruct the right ventricular outflow tract by augmenting the divided anterior leaflet with an extracellular matrix (ECM) patch to produce a competent valve. In this study, we present our preliminary experience and early outcomes. METHODS: From March 2013 to December 2015, of the 206 patients who underwent primary repair of TOF, 52 required a transannular incision...

BACKGROUND: Square knots are the gold standard in hand-tie wound closure, but are difficult to reproduce in deep cavities, inadvertently resulting in slipknots. The reversing half-hitch alternating post (RHAP) knot has been suggested as an alternative owing to its nonslip nature and reproducibility in limited spaces. We explored whether the RHAP knot is noninferior to the square knot by assessing tensile strength. METHODS: We conducted 10 trials for each baseline and knot configuration, using 3-0 silk and 3-0 polyglactin 910 sutures...

INTRODUCTION AND HYPOTHESIS: Posthysterectomy vaginal vault prolapse repair is a surgical challenge. Successful surgical management using native tissue can be achieved via the vaginal approach by iliococcygeus fascia fixation. However, although iliococcygeus fascia fixation is technically simple and has a low morbidity, it is not commonly performed. The aim of the video is to provide anatomic views and the surgical steps necessary to achieve successful transvaginal iliococcygeus fascia fixation for vaginal vault prolapse repair...

CONTEXT: Facial cosmetic result is one of the most concerning issues for the parents who get their children operated for cleft lip. Moreover, the discomfort associated with the suture removal encourages one to use any new technology that may replace the need for suture placement. The type of suture material used in surgery has been a long-standing debate among surgeons. In this study, we compared rapidly absorbable suture material (Vicryl Rapide™) with nonabsorbable suture material (nylon)...

BACKGROUND: Many factors contribute to uneventful and healthy postoperative healing. Hence, closure of periodontal flap postsurgery for the attainment of primary union between flap margins is of utmost importance. Isoamyl 2-cyanoacrylate is a tissue adhesive, which can be used for the closure of elevated flaps to overcome the problems associated with conventional suture material like silk. AIM: This study aims to compare healing after periodontal flap surgery using isoamyl 2-cyanoacrylate (bioadhesive material) and silk sutures...

The aim of this article is to compare diameter and stiffness, displacement, and strain in a five-strand versus four-strand hamstring graft for anterior cruciate ligament reconstruction. Eight matched pairs of lower extremities underwent four-strand or five-strand hamstring graft reconstruction. Diameter was significantly higher in the five-strand versus the four-strand construct (p = 0.002). No significant difference was found between the groups in construct displacement or stiffness. Significantly higher strain was observed in the inner limb versus the outer limb in the four-strand construct (p = 0...

OBJECTIVE: In elective surgery, it is well documented that a midline laparotomy should be closed with a slowly absorbable monofilament suture material in a continuous technique, in a ratio of at least 4 : 1. The evidence concerning the suture material or suturing technique in the emergency setting is lacking. We aimed to investigate whether this technique would reduce the rate of dehiscence. METHODS: A standardized procedure of closing the midline laparotomy by using a "small steps" technique of continuous suturing with a slowly absorbable (polydioxanone) suture material in a wound-suture ratio of minimum 1 : 4 was introduced in June 2014...

PURPOSE: Following tooth extraction, alveolar ridge preservation (ARP) can maintain the dimensions of ridge height and width. Although previous studies have demonstrated the effects of ARP, few if any studies have investigated the compressive force applied during grafting. The aim of this study was to determine the effects of different compressive forces on the graft materials during ARP. METHODS: After tooth extraction, sockets were filled with deproteinized bovine bone mineral with 10% porcine collagen and covered by a resorbable collagen membrane in a double-layered fashion...

We report in this paper the effects of Ethyl Ester L-Lysine Triisocyanate (LTI) on the physical-mechanical properties of Poly(lactide)/Poly(ε-caprolactone) (PLA/PCL) polyesters blends. The PLA/PCL ratios considered were 20/80, 50/50 and 80/20 (wt/wt %) and LTI was added in amounts of 0.0-0.5-1.0 phr. PLA and PCL reacted with LTI during processing in a Brabender twin screw internal mixer to produce block copolymers in-situ. The resulting blends have been characterized by torque measurements, uniaxial tensile tests, Differential Scanning Calorimeter, contact angle measurements with a Phosphate Buffered Saline (PBS) solution, ATR analysis and morphological SEM observations...

INTRODUCTION: Despite the availability of various anastomosis techniques, postoperative anastomotic complications such as anastomosis failure and bleeding develop in some patients. Automatic suturing devices have been widely used for gastrointestinal anastomosis. However, overly thick or thin tissue, displacement of tissue, and the creation of a staple-on-staple site may lead to incomplete staple formation. These factors are considered to be related to postoperative complications such as anastomosis failure...

Adhesions and scar formation between flexor tendons and the surrounding tissue are only contemporarily avoidable by movement of flexor tendons. Concepts with active follow-up protocols are more favorable than passive mobilization. The main risks of flexor tendon repair are rupture of the tendon suture, insidious gap formation and resistance to tendon gliding within the tendon sheath. Currently, there is no consensus with respect to the optimal suture technique or suture material. Nevertheless, there are some principles worth paying attention to, such as using stronger suture material, blocking stitches, suture techniques with four or more strands as well as circular running sutures...
