PURPOSE: To investigate the effect of the learning curve for small-incision lenticule extraction during the first 2 years of experience. METHODS: Small-incision lenticule extraction was performed using the 500-kHz VisuMax femtosecond laser (Carl Zeiss Meditec) by the same surgeon. The initial 100 patients since the surgeon started operating independently were considered as group 1; the recent 100 patients were considered as group 2. The same laser settings and technique were used...

PURPOSE: Inguinal herniorrhaphy is the most common general surgical procedure. It is associated with frequent complications such as recurrence (1.9% with mesh), post-operative hematoma (4.5%), reduced sensation (0 - 42.8%), chronic post-operative pain (5.1%), vasal injury (0.1 - 0.53%) and infection (3 - 6%)(1-5). Drawing on our experience utilizing the operating microscope for varicocelectomy, vasectomy reversal and repair of iatrogenic vasal obstruction from hernia repair, we employed it for inguinal hernia repair...

BACKGROUND: Loop ileostomy is a common adjunct to surgical procedures for low rectal cancers and inflammatory bowel disease. Ileostomy closure through a limited incision can be technically challenging. We hypothesized that placing a sodium hyaluronate/carboxymethylcellulose (SH/CMC) bioresorbable membrane at loop ileostomy creation would decrease stoma closure time without increasing morbidity. METHODS: In a retrospective review at a single institution with 6 board-certified colorectal surgeons, patients with loop ileostomy creation and closure between September 1999 and December 2011 were grouped based on SH/CMC placement at ileostomy creation...

The present study compares a knotless, barbed, absorbable suture material against a conventional monofilament absorbable suture material in oral mucosal wound closure. The parameters measured include time of closure and differences in healing at 2 and 4 weeks postoperatively. A prospective study comparing a knotless, barbed suture system with conventional absorbable sutures was undertaken in 19 cats. Nineteen cats had full mouth extractions performed. Following the extraction procedures, the incisions in the arcades (maxillary and mandibular) were apposed with the barbed, knotless suture system in a continuous pattern on one side and with a conventional smooth suture in an interrupted pattern on the other...

Controlateral C7 nerve root transfer in brachial plexus palsy requires a nerve graft and large incisions. This study investigated the feasibility of transferring the right C7 to the left C7 nerve root, without a graft, via a minimally invasive retropharyngeal approach. After installation of 6 trocars of 1cm diameter in the supraclavicular space, a Da Vinci SI(®) robot was placed. After locating the right brachial plexus, the C7 root was sectioned flush with the clavicle, transferred behind the pharynx and sutured to the left C7 root severed at the foramen level...

Properties of Fe minerals are poorly understood in natural soils and sediments with variable redox conditions. In this study, we combined 57Fe Mössbauer and Fe K-edge X-ray absorption spectroscopic (XAS) techniques to assess solid-phase Fe speciation along the vertical redox gradients of floodplains, which exhibited a succession of oxic, anoxic and suboxic-oxic zones with increasing depth along the vertical profiles. The incised stream channel is bounded on the east by a narrow floodplain and a steep hillslope, and on the west by a broad floodplain...

Total thyroidectomy for substernal goiter occasionally requires a sternotomy associated with a cervical incision. We sought to analyze the postoperative complications of thyroidectomy for substernal goiters in our center and more precisely the complications related to the sternotomy. All patients who underwent total thyroidectomy for substernal goiter in our center between 2007 and 2016 were reviewed retrospectively. Patients with combined cervical incision and sternotomy (ST group, n=16) were compared to those with cervical incision alone (CT group, n=54), with regard to postoperative complications...

To demonstrate surgical techniques utilized during uterine-sparing laparoscopic resections of accessory cavitated uterine masses (ACUM) BACKGROUND: ACUM represent a rare uterine entity observed in premenopausal women suffering from dysmenorrhea and recurrent pelvic pain. The diagnosis is made when an isolated extra-cavitated uterine mass is resected from an otherwise normal appearing uterus with unremarkable endometrial lumen and adnexal structures. Pathologic confirmation requires an accessory cavity lined with endometrial epithelium (and corresponding glands and stroma) filled with chocolate-brown fluid...

Wound treatment and healing is complex and is comprised of an elaborate set of processes including cellular, spectroscopic and biochemical ones as well as the "reaction" of local tissue to thermal injury. Vitamin C as l-ascorbic acid (LA) prevents injurious effects of oxidants because it reduces reactive oxygen species to stable molecules, it becomes oxidized to the short-lived ascorbyl radical. As a result, antioxidant treatment may contribute to minimizing injury in burn patients. The aim of this study is to assess changes in molecular structure of collagen extracted from human epidermis burn wound scab during incubation of the epidermis in l-ascorbic acid solution...
