A retrospective risk-adjusted analysis was completed using data from the National Surgical Quality Improvement Program (NSQIP) to (1) compare the risks of post-operative hematoma for thyroid surgery using conventional cautery compared alternative energy devices (defined as LigaSure and Harmonic Scalpel), and (2) compare operative times for the same. The primary outcome variable was post-operative hematoma occurrence. The secondary outcome variable was operative time. The exposure variable was use of conventional or alternative sources of cautery. All adult patients who underwent a total thyroidectomy, subtotal thyroidectomy or completion thyroidectomy between 2016 and 2018 were included. Multivariable linear and logistic regression analyses were performed to control for potentially confounding variables. A total of 13,330 cases were analyzed; 4342 used conventional cautery, and 8988 used alternative sources. There was a statistically significant decrease in post-operative hematoma risk using alternative sources of cautery compared to conventional cautery (OR 0.75; 95% CI 0.58–0.98) (p = 0.04). Use of alternative sources of cautery added 4.95 min onto operative time (95% CI 2.45–7.45) which was statistically significant (p < 0.0001). After controlling for confounding variables, there was a statistically significant lower rate of post-operative hematoma in thyroidectomies performed using alternative sources of cautery compared to those performed with traditional hemostatic methods. Alternative sources of cautery increased operative time by 4.95 min.

ObjectiveThe aim of this review is to determine an efficient and safe primary strategy care for paediatric epistaxis.Data sourcesWe searched PubMed and Cochrane databases for studies referenced with key words ‘epistaxis AND childhood’. This search yielded 32 research articles about primary care in childhood epistaxis (from 1989 to 2015). Bibliographic references found in these articles were also examined to identify pertinent literature. We compared our results to the specific management of adult epistaxis classically described in the literature.ResultsEpistaxis is one of the most common reasons for referral of children to a hospital ENT outpatient department. The bleeding usually originates from the anterior septum, as opposed to adults. Crusting, digital trauma, foreign bodies and nasal colonisation with Staphylococcus aureus have been suggested as specific nosebleed factors in children. Rare aetiologies as juvenile nasopharyngeal angiofibroma appear later during adolescence. There are different modes of management of mild epistaxis, which begin with clearing out blood clots and bidigital compression. An intranasal topical local anaesthetic and decongestant can be used over 6 years of age. In case of active bleeding, chemical cauterisation is preferred to anterior packing and electric cauterisation but is only feasible if the bleeding site is clearly visible. In case of non-active bleeding in children, and in those with recurrent idiopathic epistaxis, antiseptic cream is easy to apply and can avoid ‘acrobatic’ cauterisation liable to cause further nasal cavity trauma.ConclusionsAetiologies and treatment vary with patient age and the existence or not of active bleeding at the time of the examination. Local treatments are usually easy to perform, but physicians have to ponder their indications depending on the possible complications in order to inform parents and to know paediatric epistaxis specificities.

We present a method to cauterize an actively bleeding source in anterior epistaxis. In our experience, this method is efficient, provides full control of the bleeding, and ensures precise cautery of the bleeding source with minimal usage of chemical cautery sticks.

This study assessed the ability of a novel microwave coagulation surgical instrument (MWCX) to seal lymphatic vessels when compared with LigaSure (Valleylab, Boulder, CO), the Harmonic Scalpel (HS; Ethicon Endo-Surgery, Cincinnati, OH), and electric cautery. The burst pressure of pig inguinal lymphatic vessels was assessed after the sealing of vessels with each surgical instrument. The rate of lymphorrhea from pig mesenteric lymphatic vessels was also investigated using indocyanine green and visualized with the Photodynamic Eye system (Hamamatsu Hotoniks, Hamamatsu, Japan). Burst pressures were higher with MWCX (average, 300 mm Hg), LigaSure (average, 290 mm Hg), and HS (average, 253 mm Hg) when compared with electric cautery (average, 152.3 mm Hg; vs MWCX: P = .002, vs LigaSure: P = .002, vs HS: P = .004). The rate of lymphorrhea was significantly lower with LigaSure (13.3%), HS (18.8%), and MWCX (13.3%) when compared with electric cautery (77.3%; vs LigaSure: P < .001, vs HS: P < .001, vs MWCX: P < .001). MWCX was equivalent to LigaSure and HS in terms of the ability to seal lymphatic vessels.

Background Natural orifice translumenal endoscopic surgery (NOTES) is an emerging field in minimally invasive surgery that is driving the development of new technology and techniques. There are several proposed benefits to the NOTES approach, including potentially decreased abdominal pain, wound infections, and hernia formation Ko and Kalloo (Chin J Dig Dis 7:67–70, 2006 ); Wagh et al. (Clin Gastroenterol Hepatol 3(9):892–896, 2005 ); ASGE/SAGES Working Group on Natural Orifice Transluminal Endoscopic Surgery (Gastrointest Endosc 63(2):199–203, 2006 ); and Pearl and Ponsky (J GI Surg 12:1293–1300, 2008 ). Cholecystectomy has been one of the most commonly performed NOTES procedures to date, with the majority being performed through the transvaginal approach Marescaux et al. (Arch Surg 142:823–826, 2007 ); Zorron et al. (Surg Endosc 22:542–547, 2008 ); and Ramos et al. (Endoscopy 40:572–575, 2008 ). Transgastric approaches for cholecystectomy have been shown to be technically feasible in animal models and in several unpublished human patients Sumiyama et al. (Gastrointest Endosc 65(7):1028–1034, 2007 ). This video demonstrates the technique by which we perform transgastric NOTES hybrid cholecystectomy in human patients. Method Patients with symptomatic gallstone disease are enrolled under an IRB approved protocol. A diagnostic EGD is performed to confirm normal anatomy. Peritoneal access is gained using a needle-knife cautery and balloon dilation under laparoscopic visualization. Dissection of the critical view of safety is performed endoscopically. The cystic duct and artery are clipped laparoscopically and the gallbladder is dissected off of the liver. The gastrotomy is closed intralumenally and over-sewed laparoscopically. The gallbladder is extracted out the mouth. Results This technique was used to successfully perform four NOTES hybrid transgastric cholecystectomies without operative complications. Conclusions NOTES hybrid transgastric cholecystectomy can be performed safely in human patients. This procedure is still technically challenging given the current instrumentation that is available. In order to perform a pure NOTES transgastric cholecystectomy, a safe blind access method, improved retraction, endoscopic hemostatic clips, and reliable closure methods need to be developed.

Purpose To report the bench-top evaluation and initial clinical use of an instrument for onsite fenestration of aortic stent-grafts. Methods A stainless steel thermal cautery instrument was designed to create circular stent-graft fenestrations from 3 to 10 mm in diameter. Three operators independently bench-tested the instrument on thoracic stent-graft samples to evaluate size, shape, location, and quality of fenestrations created. For clinical use, on-site fenestration was performed 2 days before the endovascular procedure in a sterile room without access to supplemental oxygen. A fenestrator 1 or 2 mm smaller in diameter than the target vessel was used; the edges of the fenestrations were strengthened using flexible radiopaque nitinol wire. The aortic stent-graft was then re-sheathed and sterilized for added safety. Eighteen patients (17 men; mean age 51 years, range 18–80) with a variety of thoracic and juxtarenal pathologies were treated using Zenith TX2, Valiant Captivia, Zenith AAA, and Endurant stent-grafts modified in this manner. Results After successful bench testing, the instrument was used to create 34 fenestrations in aortic stent-grafts deployed in the 18 patients. Size and location of fenestrations obtained were as desired. Subsequent catheterization of the fenestration/target vessel and covered stent deployment were successfully achieved in 31 (91%) fenestrations; 2 fenestrations had type III endoleaks and 1 fenestration was unused. There was no perioperative mortality, stroke, embolization, vessel dissection, renal failure, or graft infection. Follow-up to 1 year in the majority of patients has revealed no new fenestration-related problems. Conclusion This simple-to-use instrument makes on-site creation of aortic stent-graft fenestrations easy, accurate, and precise. The instrument is inexpensive, robust, and easily sterilized.

Abstract BACKGROUND Large vascular brain tumors pose an exceptional challenge in young children. Choroid plexus papilloma (CPP) is an example of a rare, often large and especially vascular neuroepithelial tumor that most commonly arises in children under 5 yr old. Although patients may be cured by total resection, this tumor poses significant surgical risks and challenges related to intraoperative hemostasis. OBJECTIVE To describe our experience using a transcollation system during brain tumor surgery in a child to achieve hemostasis and minimize blood loss while preserving normal brain tissue. METHODS A 3-yr-old girl presented following a fall and was found to have a giant CPP growing from the right lateral ventricle. Given the vascularity of the tumor and the low intravascular reserve in a small child, a transcollation device was used to reduce blood loss intraoperatively. RESULTS Gross total resection was achieved with approximately 300 mL of blood loss without complications. The patient did well postoperatively. Imaging performed at 3 mo after resection revealed return of normal brain architecture. CONCLUSION Transcollation devices appear to be an effective and safe addition to the armamentarium of neurosurgical hemostatic options in intracranial tumor resection in which there is a high risk of intraoperative hemorrhage.

Reading research and incorporating valid research results into practice is a vital part of ensuring that perioperative nursing practice is evidence based. The AORN Research Evidence Appraisal Tool, which was adapted with permission from the Johns Hopkins Evidence-Based Practice Model and Guidelines, can help perioperative nurses evaluate research. This tool is used to evaluate the evidence upon which AORNs recommended practices are based. The tool can be used to appraise the level of evidence and quality of evidence for a single research study or a summary of multiple research studies. An abbreviated tool using only the sections of the tool relevant to the study appraised is included in this article. Each section of the tool is discussed to help readers understand why the study received a particular appraisal score and what that rating means to perioperative nursing practice. Clinical judgment should be used to determine whether the ndings of an individual study are of value and relevance in a particular setting or patient care situation. Individuals intending to put this studys ndings into practice are encouraged to review the original article to determine its applicability to their setting.

Choroid plexus cysts are common in the developing fetus, and although often persisting into adulthood, they rarely represent the underlying cause of symptomatic unilateral ventriculomegaly. The case presented here highlights both the diagnostic obscurity and endoscopic management of a choroid plexus cyst in a symptomatic patient. The patient is a 47-year-old white woman who presented with acute exacerbation of debilitating, diffuse, and postural headache, nausea, vomiting, early papilledema, and short-term memory loss. Cranial magnetic resonance imaging revealed an intraventricular mass obstructing the foramen of Monro on the left with ventriculomegaly. Cranial computed tomographic imaging demonstrated unilateral ventricular enlargement. During stereotactic endoscopic exploration, a choroid plexus cyst was evident at the foramen of Monro. Endoscopic cauterization of the cyst resulted in a decrease in the size of the left lateral ventricle, with complete relief of the patient's headaches and resolution of her memory loss. She remained headache free at the time of a 3-year follow-up evaluation after surgery. Choroid plexus cysts remain a diagnostic challenge; their presence should be sought out in the face of ventricular asymmetry and symptomatic hydrocephalus. Endoscopic ablation offers a minimally invasive treatment for the management of these lesions.
