A Study Comparing Skin Adhesive With Staple for Surgical Incision Closure After Laparoscopic / Robotic Bowel Resection

ABSTRACT: INTRODUCTION Liquid skin adhesive (LSA) has benefits over other closure methods. Especially it is less invasive, quicker to apply, and better in cosmesis. Also LSA applied wounds need no post-care and its water-proof nature allows patients to take a shower immediate postoperative periods. While traditional sutures and skin staples are invasive and have infection chance requiring regular wound dressings, LSA is resistant against both water and microbial infection without need for postoperative dressings. Thus LSA-applied wounds need no professional care saving wound management cost. This study investigated not only the safety and efficacy of LSA, but also the cost-effectiveness in the context of total wound management resources including man-power, time, and cost. STUDY OBJECTIVE Primary end point of this study is time requiring to manage surgical wound calculated as man hour. Secondary end points are wound related complication and cost for management of surgical wound. STATISTICAL ANALYSIS The target number of the enrollment were calculated under the hypothesis that the wound management time for stapler group would be 1560 sec and that for LSA group be 264 sec with 10% drop-out rate. The sample number calculation formula of the t-test for independent 2 groups were used. For two-sided validation with the significance level of 0.05, and the power of 0.8, 29 patients for each group were estimated.

Project description:Perfluorooctane sulfonate (PFOS) has been manufactured for over 50 years in increasing quantities and has been used for several industrial and commercial aims. Due to the persistence and the bioaccumulation of this pollutant, it can be found worldwide in wildlife and humans. Biochemical effects of PFOS exposure are mainly studied in mammalian model species and information about effects on fish species remain largely scarce. This lack of toxicity data points out that there is an urgent need for the mechanistic molecular understanding of the mode of action of this pollutant. In the present study, common carp (Cyprinus carpio) was exposed through water for 14 days at concentrations of 0.1; 0.5 and 1 mg/l PFOS. Liver was selected as target tissue. Custom microarrays were constructed from cDNA libraries obtained with Suppression Subtractive Hybridization-Polymerase chain reaction (SSH-PCR) experiments. Microarray data revealed that the expression of several genes in the liver was influenced by PFOS exposure and real-time PCR was used to confirm these gene expression changes. The affected genes were mainly involved in energy metabolism, reproduction and stress response. Furthermore, the relative condition factor and the hepatosomatic index of the exposed fish were significantly lower after 14 days of exposure as well as the available glycogen reserves. At all levels of biological organization, indications of a trade-off between the metabolic cost of toxicant exposure on one hand and processes vital to the survival of the organism on the other hand were seen. Our results support the prediction that increases in energy expenditure negatively affects processes vital to the survival of an organism, such as growth. Keywords: PFOS, common carp, microarray, condition factor, energy reserves, metabolic cost There were 3 biological replicates for each exposure concentration. For each biological replicate control versus exposed hybridizations were carried out. The mean of the biological replicates was calculated for the differentially expressed genes.
