BACKGROUND: Recently, several new imaging technologies, such as three-dimensional (3D)/high-definition (HD) stereovision and high-resolution two-dimensional (2D)/4K monitors, have been introduced in laparoscopic surgery. However, it is still unclear whether these technologies actually improve surgical performance. METHODS: Participants were 11 expert laparoscopic surgeons. We designed three laparoscopic suturing tasks (task 1: simple suturing, task 2: knotting thread in a small box, and task 3: suturing in a narrow space) in training boxes...

INTRODUCTION: Recent advances in single-incision laparoscopic surgery (SILS) have caused increased difficulties when tying knots because of the limited working space. Although extracorporeal knot-tying techniques may be a practical alternative choice in SILS, it is not always appropriate. For example, sliding resistance may be encountered when tying knots for a Z-shaped suture, and it could damage the sutured tissue. MATERIALS AND SURGICAL TECHNIQUE: The clinch knot is a kind of slipknot that has been historically used by fishermen...

There has been a growing number of patients asking for a lighter face lift than the classical biplane procedure with wide undermining; This explains the popularity of medical threads lifts. A surgical approach is nevertheless possible by performing a new technique, derived from minilfts, but with a dissection elevating skin and SMAS layers together, preserving as much retaining ligaments as possible, and allowing a predesigned skin excision. Thirty-two patients have been operated this way since 2014; 3 asked and sustained for a redo because of skin relapse at one year postoperatively...

INTRODUCTION: Although nonsurgical methods and many surgical techniques have been developed for repairing a ruptured Achilles tendon, there is no consensus on its best treatment. In this article, a novel minimally invasive technique called the Panda Rope Bridge Technique (PRBT) is described. METHODS: Patient with acute Achilles tendon rupture was operated on in the prone position. The PRBT begin with making the proximal bridge anchor (Krackow sutures in the myotendinous junction), the distal bridge anchor (two suture anchors in the calcaneus bone) and the ropes (threads of the suture anchors) stretched between the anchor sites...

Although dural tears are a frequent complication of lumbar spine surgery, no standardized method exists for their treatment. Given the growing number of spinal procedures performed worldwide, it is important to codify an effective strategy for managing repair of the dura mater. This paper is a review of the comparative effectiveness of the current treatments available for dural tears. Our findings suggest that, where possible, repair should be made via direct suturing using material that minimizes the difference between the size of needle and thread...

BACKGROUND: In the meniscal repair procedures, a high ultimate load capacity and low cyclic creep at the repair site are favorable and lead to good biological incorporation of the tear site after surgery. Previous biomechanical tensile tests of the meniscal sutures have identified the suture knot as the weakest point. We hypothesized that the strength of a suture knot depends on the suture shape, and therefore, we compared three differently shaped suture materials composed of the same material and quantity per length...
