OBJECTIVE: Proficient open surgical treatment of cerebral aneurysms requires extensive training and practice. The goal of this study was to test the validity of a human placenta aneurysm model for surgical simulation training of aneurysm clipping. METHODS: Thirty participants were divided into 3 groups (n=10 per group) according to their neurosurgical experience: low experience, intermediate experience, and attending. Subjective measures were collected using the Aneurysm Clipping Participant Survey (n=27)...

BACKGROUND: Although a rerupture after surgical clipping of ruptured intracranial aneurysms is rare, it is associated with high morbidity and mortality. The causes for retreatment and rupture after surgical clipping are not clearly defined. METHODS: From a prospectively maintained database of 244 patients who had undergone surgical clipping of ruptured intracranial aneurysms, we selected patients who experienced retreatment or rerupture within 30 days after surgical clipping...

OBJECTIVE Smoking is a known risk factor for aneurysm development and aneurysmal subarachnoid hemorrhage, as well as subsequent vasospasm in both untreated individuals and patients who have undergone surgical clipping of cerebrovascular aneurysms. However, there is a lack of data in the current scientific literature about the long-term effects that smoking has on the integrity of endovascular repairs of cerebral aneurysms. This study was designed to determine if any smoking history increased the risk of poorer outcomes and/or aneurysm recurrence in patients who have had endovascular repair of cerebral aneurysms...

INTRODUCTION: Aneurysms of the carotid-ophthalmic segment are relatively rare, comprising only five percent of all intracranial aneurysms. There is no consensus regarding the optimal management for ruptured carotid-ophthalmic aneurysms, whether endovascular coiling or surgical clipping provide the most favourable patient outcome. The aim of this meta-analysis is to analyse these two treatment modalities for ruptured carotid-ophthalmic aneurysms with respect to independent clinical outcome...

BACKGROUND: Unruptured intracranial aneurysms (UIAs) are increasingly diagnosed and are commonly treated using endovascular treatment or microsurgical clipping. The safety and efficacy of treatments have not been compared in a randomised trial. How to treat patients with UIAs suitable for both options remains unknown. METHODS: We randomly allocated clipping or coiling to patients with one or more 3-25 mm UIAs judged treatable both ways. The primary outcome was treatment failure, defined as: initial failure of aneurysm treatment, intracranial haemorrhage or residual aneurysm on 1-year imaging...

Background A growing number of operations are performed using minimally invasive techniques. Therefore, a lot of new requirements must be met by the staplers currently available. At the present time, the most widely used methods of minimally invasive vascular occlusion involve high-frequency energy, clips, and staplers. The most important quality parameter is burst pressure, which is measured with a variety of experimental set-ups, all of which are subject to criticism. With this study, we want to introduce a fully automated vascular burst pressure measuring system that largely mimics physiological conditions...

The objective of this research was to clinically compare peri-implant tissue health of bar-clips versus silicone-resilient liners used with bilateral posterior bars for retaining four implant supported mandibular overdentures. Thirty completely edentulous male patients (mean age 65) were randomly assigned into two equal groups. Each patient received four implants in canine and first molar regions of the mandible using flapless surgical technique. Mandibular overdentures were immediately connected to the implants with bilateral prefabricated instant adjusting bars...

BACKGROUND: The ability of characteristics to predict first time performance in laparoscopic tasks is not well described. Videogame experience predicts positive performance in laparoscopic experiences but its mechanism and confounding-association with aptitude remains to be elucidated. This study sought to evaluate for innate predictors of laparoscopic performance in surgically naive individuals with minimal videogame exposure. METHODS: Participants with no prior laparoscopic exposure and minimal videogaming experience were recruited consecutively from preclinical years at a medical university...

OBJECTIVE: To assess the relationship between robotic surgical simulation performance and the real-life surgical skill of attending surgeons. We hypothesized that simulation performance would not correlate with real-life robotic surgical skill in attending surgeons. DESIGN: In 2013, Birkmeyer et al. demonstrated an association between laparoscopic surgical performance as determined by expert review of video clips and surgical outcomes. Using that model of expert review, we studied the relationship between robotic simulator performance and real-life surgical skill...

Recently, endoscopic submucosal dissection (ESD) for the duodenal tumors has come to be treated in many institutions, but has also showed many problems of feasibility and safety compared with endoscopic mucosal resection (EMR). Although duodenal ESD is expected to be more effective for the prevention of postoperative local recurrence, high incidence rate of duodenal perforation and emergency surgical rescue are big problem. Prophylactic mucosal closure by clipping device, polyglycolic acid sheets shielding, and the laparoscopic and endoscopic cooperative surgery are reported to be effective measures to overwhelm the various problems associated with duodenal ESD...

Among the various diagnostic modalities for small bowel hemangioma, video capsule endoscopy (VCE) and double-balloon enteroscopy (DBE) can be recommended as part of the work-up in patients with obscure gastrointestinal bleeding (OGIB). DBE is superior to VCE in the accuracy of diagnosis and therapeutic potential, while in most cases total enteroscopy cannot be achieved through only the antegrade or retrograde DBE procedures. As treatment for small bowel bleeding, especially spout bleeding, localization of the lesion for the decision of DBE insertion facilitates early treatment, such as endoscopic hemostatic clipping, allowing patients to avoid useless transfusion and the worsening of their disease into life-threatening status...

Purpose  Simulation training offers a useful opportunity to appreciate vascular anatomy and develop the technical expertise required to clip intracranial aneurysms of the posterior circulation. Materials and Methods  In cadavers, a comparison was made between the endoscopic transclival approach (ETA) alone and a combined multiportal approach using the ETA and a transorbital precaruncular approach (TOPA) to evaluate degrees of freedom, angles of visualization, and ergonomics of aneurysm clip application to the posterior circulation depending on basilar apex position relative to the posterior clinoids...

Laparoscopic donor nephrectomy (LDN) is the gold standard for kidney donation. Recent literature has led to considerable debate regarding the safest route to provide vascular control during this procedure. The most common devices used for vascular control during LDN are staplers and surgical clips. Opinions regarding the safety of these devices vary, as both are prone to dysfunction. Certain clips have already been contraindicated for use on the donor artery owing to reports of catastrophic complications of falling off...

In incidental aneurysms, endovascular treatment can lead to post-procedural headaches. We studied the difference of surgical clipping vs. endovascular coiling in concern to post-procedural headaches in patients with ruptured aneurysms. Sixty-seven patients with aneurysmal subarachnoidal haemorrhage were treated in our department from September 1(st) 2015 - September 1(st) 2016. 43 Patients were included in the study and the rest was excluded because of late recovery or high-grade subarachnoid bleedings. Twenty-two were surgical treated and twenty-one were interventionally treated...

Blister aneurysms are rare cerebrovascular lesions for which the treatment methods are reviewed here, with a focus on endovascular options. The reported pathogenesis of blister aneurysms varies, and hemodynamic stress, arterial dissection, and arteriosclerotic ulceration have all been described. There is consensus on the excessive fragility of blister aneurysms and their parent vessels, which makes clipping technically difficult. Open surgical treatment is associated with high rates of complications, morbidity, and mortality; endovascular treatment is a promising alternative...
