Laparoscopic and endoscopic cooperative surgery for duodenal tumor is the precise oncologic resection procedure and the closure of the defect (1). Non-exposed Endoscopic Wall-inversion Surgery (NEWS) is a novel minimally invasive technique for gastric submucosal mass (SMT) and early gastric cancer having advantageous precision to determine the resection line with no risk of peritoneal contamination (2-5). We describe the NEWS technique that we applied and performed for a small duodenal SMT. This article is protected by copyright...

BACKGROUND: The availability of minimal access instrumentation and endoscopic visualization has revolutionized the field of minimally invasive skull base surgery. The transorbital endoscopic approach using an eyelid incision has been proposed as a new minimally invasive technique for the treatment of skull base pathology, mostly extradural tumors. Our study aims to evaluate the anatomical aspects and potential role of the transorbital endoscopic approach for exposure of the sylvian fissure, middle cerebral artery and crural cistern...

Ventral body wall (VBW) defects are among the most common congenital malformations, yet their embryonic origin and underlying molecular mechanisms have remained poorly characterized. Although transforming growth factor beta (TGF-β) signalling is essential for VBW closure the responding cells are not known. Here we identify a population of migratory myofibroblasts at the leading edge of the closing VBW that express the actin-binding protein Transgelin (TAGLN) and TGF-β receptor (TGFβR). These cells respond to a temporally regulated TGF-β2 gradient originating from the epithelium of the primary body wall...

OBJECTIVE: Urethral diverticulum is uncommon, therefore appropriate evaluation, preoperative planning and counseling must be done in order to make correct diagnosis and prevent complications. MATERIALS AND METHODS: A case of anterior vaginal wall mass was treated elsewhere by a gynecologist as periurethral cyst abscess; incision and drainage were done but a symptom of pus discharge was observed after 2 weeks. Therefore, exploration, cyst wall excision and primary closure were done though histopathological examination surprisingly confirmed the presence of urethral tissue suggestive of diverticulum...

In this study, we have reproduced the cough clearance process with an Eulerian wall film model. The simulated domain is based on realistic geometry from the literature, which has been improved by adding the glottis and epiglottis. The vocal fold movement has been included due to the dynamic mesh method, considering different abduction and adduction angles and velocities. The proposed methodology captures the deformation of the flexible tissue, considers non-Newtonian properties for the mucus, and enables us to reproduce a single cough or a cough epoch...

INTRODUCTION: Treatment of a tooth with necrotic pulp and open apex is a special challenge to the clinicians. Apexification with calcium hydroxide and MTA barrier technique fails to induce continued root maturation which makes the tooth susceptible to root fracture. Hence, an ideal outcome for such a tooth should be regeneration of pulp like tissue into the root canal capable of continuing normal root maturation. AIM: This study aims to compare the effect of Platelet Rich Fibrin (PRF), induced bleeding technique and Platelet Rich Plasma (PRP) in the revascularization of tooth with necrotic pulp and open apex...

Patent ductus arteriosus (PDA) is a congenital cardiovascular defect in which a fetal connection between the aorta and pulmonary artery does not spontaneously close shortly after birth. If left uncorrected serious complications and even death can occur. Surgical ligation is the traditional treatment method; however, it is an invasive procedure, that motivates development of a minimally invasive option. Shape memory polymer (SMP) foams are unique materials that hold promise in the field of minimally invasive occlusion devices...

BACKGROUND: Spinal extradural arachnoid cysts (SEAC) are relatively rare and usually asymptomatic. They preferentially are situated in the thoracic extradural space, and almost always dorsal. SEACs may present with back pain and/or cord compression symptoms. Needle aspiration, needle fenestration or open surgical resection/fenestration have been reported as treatment modalities. CASE DESCRIPTION: We present a 35-year-old woman who complained of radiating pain from the right lower thoracic region of her back towards the right inguinal region which was aggravated upon defecation and straining...

BACKGROUND: Repair of large incisional hernias remains a surgical and costly challenge. Temporary paralysis of the lateral abdominal wall muscles with topical administration of botulinum toxin A (BTA) is a new therapeutic concept, which may obviate the need for component separation technique (CST) for repair of large incisional hernias. Current literature on the administration of BTA as adjunct to surgical repair of abdominal incisional hernias was investigated. METHODS: The electronic databases PubMed and Embase were searched for eligible studies...

INTRODUCTION: Operative management of complex ventral hernia still remains a significant challenge for surgeons. Closure of large defects in the unprepared abdomen has serious pathophysiological consequences due to chronic contraction and retraction of the lateral abdominal wall muscles. We report outcomes of 56 consecutive patients who had preoperative Botulinum toxin A (BTA) abdominal wall relaxation facilitating closure and repair. METHODS: This was a prospective observational study of 56 patients who underwent ultrasound-guided BTA into the lateral abdominal oblique muscles prior to elective ventral hernia repair between November 2012 and January 2017...

The connectivity of rocks' porous structure and the presence of fractures influence the transfer of fluids in the Earth's crust. Here, we employed laboratory experiments to measure the influence of macro-fractures and effective pressure on the permeability of volcanic rocks with a wide range of initial porosities (1-41 vol. %) comprised of both vesicles and micro-cracks. We used a hand-held permeameter and hydrostatic cell to measure the permeability of intact rock cores at effective pressures up to 30 MPa; we then induced a macro-fracture to each sample using Brazilian tensile tests and measured the permeability of these macro-fractured rocks again...

USP <1207.1> Section 3.5 states that "A deterministic leak test method having the ability to detect leaks at the product's maximum allowable leakage limit is preferred when establishing the inherent integrity of a container-closure system." Ideally, container closure integrity (CCI) of parenteral packaging would be evaluated by measuring a physical property that is sensitive to the presence of any package defect that breaches package integrity by increasing its leakage above its maximum allowable leakage limit (MALL)...

OBJECTIVE: To investigate the security and efficacy of a new endoscopic closure method of large defects after endoscopic full-thickness resection (EFTR) double purse-string suture using two endoloops and metallic clips via single-channel endoscopy. METHODS: Clinical data of 23 cases with submucosal tumors (SMT) who received endoscopic resection from June 2015 to July 2016 in our National Cancer Center were collected. For gastric and esophageal SMTs or the mucosa layer injured during submucosal tunneling endoscopic resection (STER), double purse-string suture was conducted after EFTR...

OBJECTIVES: To investigate the effect of experimental diabetes and metabolic control on intramembranous bone healing following guided bone regeneration (GBR). MATERIAL AND METHODS: Ninety-three Wistar rats were allocated to three experimental groups, healthy (H), uncontrolled diabetes (D) and controlled diabetes (CD). Twenty one days following diabetes induction, a standardised 5-mm defect was created at the mid-portion of each parietal bone. In 75 animals (25H, 25D, 25CD), one defect was treated with an intracranial and extracranial membrane according to the GBR principle, and one defect was left empty (control); five animals per group were then randomly sacrificed at 3, 7, 15, 30 and 60 days and processed for decalcified histology...

INTRODUCTION: The optimal management of the open abdomen (OA) after liver transplantation (LT) is unclear. The negative pressure wound therapy (NPWT) has been shown to be safe and can increase the chance for early fascial closure in trauma or septic patients. However, little data are available on the specific setting of LT. We aimed to report our experience of OA after LT, marked by the recent use of NPWT. METHODS: All patients with postponed wall closure after LT, from 2002 to 2014, in a single institution were included and retrospectively analyzed...

Velopharyngeal insufficiency (VPI) represents an incomplete closure between the soft palate and the posterior pharyngeal wall. Its etiology can be anatomical (cleft palate), neurologic, or iatrogenic (after adenoidectomy). The evaluation of a VPI begins with a through speech and language assessment and can be complemented by instrumental investigations. VPI treatment relies on its early identification, followed by a specific speech therapy management. Surgery is performed in case of no improvement with speech therapy or in case of an anatomical defect not allowing the child to improve...

BACKGROUND: In large incisional hernias and after laparostoma midline closure may be impossible. A novel abdominal wall expander system (AWEX) is proposed and evaluated. METHODS: In patients with large incisional hernias and laparostoma where primary midline closure was impossible, AWEX was used. Patients undergoing abdominal wall reconstruction using AWEX between May 2012 and December 2015 were included. Intraoperative the abdominal wall was stretched by attaching the midline fascia borders to a retraction system under tension for 30 minutes...
