Abstract:

In recent years, many efforts have been made to reduce the trauma of surgical access further by the use of single-incision laparoscopic surgery (SILS). The Ergo-Lap (ergonomic laparoscopic) simulator was taken to the 20th International Congress of the European Association for Endoscopic Surgery (EAES) in 2012 in Brussels, Belgium. During the congress, the simulator was assessed by 13 general surgeons with different SILS experience using a standardized questionnaire to determine the usability of the Ergo-Lap simulator training for basic SILS skills. Eleven of the 13 participants rated the simulator as an attractive simulator (attractive here means arousing interest of the trainees). For the aspects of training in an ergonomic way, 12 of 13 participants rated it as good to excellent because the work space and task panel location can be adjusted according to the length of instruments. Also, 92% (12 of 13) thought the Ergo-Lap simulator was useful for practicing basic SPLS skills. And 85% (11 of 13) thought it was very easy to use. For SILS skills training, this inexpensive and portable Ergo-Lap simulator offers a feasible training opportunity to help trainees practice their SILS skills under ergonomic conditions.

Abstract:

Formation of a post-operative trocar site hernia (TSH) is a serious complication of laparoscopic surgery with an incidence of 1.5%–1.8%, and may necessitate emergent surgical correction in the case of bowel strangulation. Many contributing factors increase the risk of this complication, and various surgical devices have been developed to help prevent post-operative TSH formation. Bladeless trocars with radially expanding technology have been shown to decrease the incidence of post-operative TSH. Various port site closure devices are also available on the market, which assist in closing the fascia, thus decreasing the risk of this complication. In this article, we will review the use of these devices and their potential to reduce post-operative TSH formation.

Abstract:

Surgical candidates are often immunosuppressed patients. Immunodeficiency associated with malnutrition are risk factors for developing postoperative SSI. The term “immunonutrition” refers to the addition of omega-3 fatty acids, glutamine and arginine to liquid nutritional supplements. Diverse studies have shown a reduction in septic complications after perioperative use of immunonutrition, but these results could not be confirmed by other authors. In this issue, we will review the actual evidence about the effect of immunonutrition on the prevention of SSI.

Abstract:

The aim of the current prospective study was to evaluate the biomechanical stability of barbed suture vs. conventional suture. Biomechanical stability of a 14x14-cm PDO/polydioxanone, with a half circle and 36-mm needle, bidirectional barbed 0-Quill suture (Angiotech, Vancouver, British Columbia, Canada) vs. 1-Poliglecaprone 25 (Monocryl, Ethicon, Inc, Somerville, NJ) suture was evaluated on biological specimens. The 1-Monocryl suture was chosen because it is widely used by gynecological surgeons in the repair either of the vaginal cuff or the uterine wall defects. Forty specimens of aponeurotic muscle, obtained from abdominal wall of a lamb, were prepared, and randomly assigned to 1 of 2 repair groups: Group A (n = 20) classic repair with 1-Monocryl suture; Group B (n = 20) 0-Quill barbed suture. Each specimen was transected at the midpoint and then repaired. Biomechanical stability of the repaired specimen was verified on a CMT6000 electromechanical universal testing machine (SANS, MTS SYSTEMS, China Co., Ltd., Shenzhen, China), with a 1kN cell. Biomechanical tests showed that maximum force was similar for 1-Monocryl and 0-Quill respectively (p = non-significant). This randomized laboratory study shows that biomechanical stability of the sutures is comparable.
