Filter by:In the past two decades, the femtosecond laser (FSL) technology has been introduced in the corneal refractive surgery filed, and brought a remarkable innovation. It can make tissue dissection through photodisruption and plasma cavitation. Initially, the FSL was used predominantly to make a corneal flap when performing laser in situ keratomileusis (LASIK), which is followed by stromal ablation using excimer laser. A new surgical technique called femtosecond lenticule extraction (FLEx) has been developed that uses only FSL to dissect two interfaces to create refractive lenticule and then remove it, which is very similar with LASIK. Small incision lenticule extraction (SMILE) which is the advanced form of all-in-one FSL refractive technique does not make a corneal flap rather make small incision where the separated refractive lenticule is removed through, and the upper part of the corneal tissue is called cap. Since the clinical outcomes of SMILE were firstly published in 2011, SMILE has been widely used for correction of myopia or myopic astigmatism worldwide. SMILE provides excellent visual outcomes and has advantages including a lesser decrease in corneal sensitivity and absence of flap related complications compared to LASIK. Because corneal ectasia after refractive surgery is the one of most terrifying complication, corneal biomechanics has been drawn interests to many researchers and clinicians. Theoretically, SMILE may preserve corneal biomechanics better than LASIK, because the anterior stroma which is stiffer than the posterior stroma remains intact in SMILE. However, there are some controversies, because previous studies investigating corneal biomechanics have been reported inconsistent outcomes, although SMILE has been reported equal to or better than LASIK. Weakening of corneal biomechanics and iatrogenic corneal ectasia have also been reported after SMILE. In addition, because the tensile strength of cornea gradually decreases as it goes backwards, creating deeper refractive lenticule may result in stronger cornea by preserving more of anterior lamellae of the cornea. But on the contrary, leaving sufficient residual stromal bed has been known to be important in preventing iatrogenic corneal ectasia, hence creating thin cap may be effective and desirable. Although many researches have been investigated the difference in biomechanical response between SMILE and LASIK, there are few studies evaluating the dependence of cap thickness on postoperative biomechanical strength after SMILE. El-Massry et al. reported that the thicker cap thickness showed higher postoperative corneal hysteresis (CH) and corneal resistance factor (CRF) with Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Depew, NY) which may not be optimal for a clear description of the viscosity and elasticity of the cornea,3 ; however, other studies have been presented that there is no significant difference of corneal biomechanics with cap thickness. There is no comparative human study using Corvis ST (Oculus, Wetzlar, Germany) despite presence of the study using Corvis ST in rabbit eyes. Furthermore, no prospective study with large number of subjects has been performed to date.
The use of topical beta-blockers, such as 0.25% timolol, in promoting wound healing is currently emerging in the academic literature. The investigators will enroll 82 patients who have their skin cancer surgically removed resulting in the need of a full-thickness skin graft. The objective of this randomized safety study is to determine the safety and efficacy of 0.25% timolol in promoting wound healing in full-thickness skin grafts compared to standard of care.
To determine the efficacy on decreasing the rate of surgical wound complications in patients undergoing repair of large incisional hernias, after the prophylactic application of a single-use negative pressure therapy dressing (PICO), versus a conventional dressing.
The main objective is to study the efficacy of topical antibiotic therapy with Amoxicillin / Clavulanic acid in the prevention of surgical wound infection in patients undergoing to colorectal surgery
The objective of the trial is to demonstrate the safety and effectiveness of the Cardiva Mid-Bore Venous Vascular Closure System (VVCS) in sealing femoral venous access sites at the completion of catheter-based procedures performed through 6-12 Fr introducer sheath, while allowing for one or more of the following: elimination of the Foley catheter, elimination of protamine, or allowing same (calendar) day discharge for the appropriate patient population.
The aim of the present study is to assess effect of local wound infiltration in comparison with caudal block by bupivacaine 0.25% after inguinal herniotomy in pediatrics on: Wound infection and healing (primary outcome) and postoperative analgesia (secondary outcome).
RESEARCH PROJECT OBJECTIVES The aim of this planned study is to evaluate factors, with particular reference to surgical technique of abdominal closure, accumulation of advanced glycation end products, and collagen content in the transversalis fascia, that are associated with the development of incisional hernias after transverse epigastric incisions in patients operated due to malignant tumors. RESEARCH PROJECT METHODOLOGY: The study is designed as prospective and is planned to include 392 patients undergoing abdominal surgery due to malignant tumors of the alimentary system performed through transverse incisions in the epigastrium. Primary end-point of the study is defined as the occurrence of burst abdomen during immediate postoperative period or incisional hernia over 2 year postoperative follow-up. Assessment of the association between the type of surgical technique and development of hernia will be based on comparison of mass (1 layer) continuous suture and layered (2 layers) continuous suture using slowly absorbable material and applying suture to wound length ratio of more than 4. Type of the utilized surgical technique will be based on randomization. The method of abdominal closure will remain unknown for patients and investigators assessing the presence of incisional hernias. Assessment of overall collagen content and type I to type III ratio will be performed by obtaining a fragment of tissue during operation, preparation of formalin-fixed and paraffin embedded blocks, cutting of 4-micrometer thick sections, staining with picrosirius red and immunohistochemical procedures. Images will be analyzed with dedicated computer software. Accumulation of advanced glycation end products will be evaluated indirectly by measuring skin autofluorescence utilizing a method based on the use of photodiodes. Postoperative follow-up will include the period of postoperative hospitalization and two additional control visits at 1 and 2 years after the operation. Assessment of the presence of incisional hernia will comprise clinical examination, ultrasonographical study, and analysis of images from other available radiological studies. Irrespective of the primary end-point, additional analyses will be performed concerning associations between evaluated factors and occurrence of burst abdomen and the impact of incisional hernia on patients quality of life using the EORTC QLQ C-30 questionnaires. Statistical analyses will, among other, include Kaplan-Meier method, log-rank test, Cox proportional hazards regression and logistic regression
Patients undergoing routine surgery in the Department of Dermatology for any indication on non-scalp skin and closed in linear fashion with scar greater than or equal to 4.5cm in length will be invited to participate in this split scar, head to head study comparing zinc oxide and petrolatum. Patients will apply respective ointments to each half of scar daily for one month and maintain a log of these activities. They will be seen at 1 week, 4 weeks, 8 weeks, and 6 months post-operatively for photographic scar assessment and to complete the patient portion of the Patient and Observer Scar Assessment Scale (POSAS), a quantitative objective assessment of scar appearance. Trained observers (board-certified dermatologists) will score the observer portion of the scale. POSAS outcomes, post-operative infections, linear density of epidermal seal will be assessed at the 1 week, 4 weeks, 8 weeks, and 6 months post-operative periods and compared between the two groups. Participants will have parking validated for all visits and upon completion of all portions of the study will receive a standardized skin care gift bag containing samples for hypoallergenic skin care products (washes, moisturizers, etc.).
Aim of study was clinical comparative evaluation of using modified vertical internal mattress suturing technique and simple loop interrupted suturing technique in the outcome of modified Widman flap surgery for the management of chronic periodontitis.
Postoperative pain is an important clinical issue which negatively affects patient's satisfaction, delays discharge and repeated admission after discharge in orthopedic surgery. Peripheral nerve blocks are commonly used for postoperative analgesia as an adjunct to analgesic drugs. The aim of this study is to evaluate the effect of ankle blocks performed at the end of the surgery on postoperative discharge times, postoperativeanalgesia, patient's satisfaction, additional analgesic requirements, and complications in patients undergoing orthopedic foot surgery.
