Ventricular paired pacing to control intractable junctional tachycardia following open heart surgery in a child.
1989
A 5-month-old girl presented postoperatively with an atrioventricular (A-V) junctional tachycardia at a rate of 245/min following surgical repair of tetralogy of Fallot. The systolic blood pressure dropped to 60 mmHg with this rapid heart rate, and the infant became shocked. Drugs and overdrive pacing were ineffective in suppressing the A-V junctional tachycardia and in improving cardiac output. Ventricular paired pacing was used successfully to halve the mechanically effective ventricular rate and to restore cardiac output. When ventricular paired pacing was stopped after 12 h, the spontaneous rhythm was an atrial rhythm with 1-1 A-V conduction. The patient was discharged in sinus rhythm o…
Innovative fully robotic 4-arm Ivor Lewis esophagectomy for esophageal cancer (RAMIE4).
2019
Nowadays robotic surgery is established for abdominal and thoracic surgery. It has been shown that complex procedures are feasible using robotic systems, e.g., da Vinci Xi, with a huge benefit in precision. Different techniques for esophageal cancer surgery are reported; however, only a few robotic and partial robotic procedures are described. Therefore, a fully robotic (abdominal and thoracic) Ivor Lewis esophageal resection using four robotic arms-RAMIE4-the standard technique used for lower esophageal cancer, is presented in this paper. The technique shown in the video was performed successfully in 100 cases in 24 months. The reconstruction is performed with a gastric conduit pull-up and…
Corticotomies as a surgical procedure to accelerate tooth movement during orthodontic treatment : a systematic review
2015
Background One of the main aims of orthodontists is to reduce the treatment time as much as possible, particularly in view of the rise in demand for orthodontic treatment among adult patients. The objective of this systematic review was to examine the effectiveness of corticotomy as a surgical procedure that accelerates orthodontic tooth movement, together with its possible adverse effects. Material and Methods A systematic review of articles in 4 databases, Pubmed, Cochrane, Scopus and Embase, complemented by a manual search, identified 772 articles. The duplicates were eliminated and a critical reading of titles and abstracts led to the rejection of articles that did not meet the objectiv…
Robotic-assisted minimally invasive esophagectomy (RAMIE) for esophageal cancer training curriculum—a worldwide Delphi consensus study
2021
Summary Background Structured training protocols can safely improve skills prior initiating complex surgical procedures such as robotic-assisted minimally invasive esophagectomy (RAMIE). As no consensus on a training curriculum for RAMIE has been established so far it is our aim to define a protocol for RAMIE with the Delphi consensus methodology. Methods Fourteen worldwide RAMIE experts were defined and were enrolled in this Delphi consensus project. An expert panel was created and three Delphi rounds were performed starting December 2019. Items required for RAMIE included, but were not limited to, virtual reality simulation, wet-lab training, proctoring, and continued monitoring and educa…
Endoureterotomy with the Lovaco technique for treatment of ureterointestinal strictures: outcomes in an experienced center and factors associated wit…
2021
INTRODUCTION The study aimed to present the outcomes of an endoureterotomy series using the Lovaco technique for the treatment of ureterointestinal strictures. Factors influencing the success or failure of this technique were also determined. MATERIALS AND METHODS Data were collected from all endoureterotomies for ureterointestinal strictures performed in a single-center between 2017 and 2020. Clinical variables and characteristics of the stricture were recorded in each case, and success was defined as the complete resolution of ureterohydronephrosis. Univariate analysis was used to correlate the variables recorded with procedural success or failure. RESULTS A total of 25 patients were recr…
Tranexamic acid in cardiac surgery: Are low doses enough?
2020
OBJECTIVES Tranexamic acid is used to prevent hyperfibrinolysis and reduce postoperative bleeding and blood transfusions in on-pump cardiac surgery. We evaluate the efficacy of low or high dose tranexamic acid in a prospective cohort study conducted in Valencia. MATERIALS AND METHODS A total of 427 patients were recruited between January 2019 and January 2020, 207 in the Hospital General Universitario (low dose [LD]) and 220 in the Hospital Universitario y Politecnico La Fe (high dose [HD] and intermediate dose [ID]). We recorded the presence of hyperfibrinolysis on rotational thromboelastometry, intra- and postoperative administration of blood products, chest tube output within the first 1…

Renal transplantation by automatic anastomotic device in a porcine model
2015
Automatic vascular staplers for vascular anastomoses in kidney transplantation may dramatically reduce the operative time and, in particular, warm ischemia time, thus increasing the outcome of transplantation. Ten pigs underwent kidney auto-transplantation by automatic anastomotic device. Kidneys were collected by laparotomy with selective ligations at the renal hilum and perfused with cold storage solution. To overcome the shortage in length of renal hilum, a tract of the internal jugular vein was harvested to increase the length of the vessels. The anastomoses were totally performed by the use of the anastomotic device. On 10 kidney transplants, nine were successful and no complications o…
German neuroendoscopy above the skull base
2009
Endoscopy plays an important part in current minimally invasive neurosurgery. The concepts, indications, and standards of current neuroendoscopy were developed in the beginning of the 1990s by several groups of neurosurgeons. Several factors contributed to its success and acceptance, including technical development, influence of other disciplines, and adaptation to neurosurgical requirements. This historical survey focuses on the period when this technique initially emerged, including the scientific discussions of each group as well as the arguments and reasons that led to present intraventricular neuroendoscopy. Interestingly, despite the almost independent development of neuroendoscopic s…
Surgical Treatment for Traumatic Brain Injury: Is It Time for Reappraisal?
2015
Traumatic brain injury (TBI) is a major cause of morbidity and mortality in the United States. It is estimated that each year, on average, TBIs associated with 1.1 million visits to the emergency department, 235,000 hospitalizations, and 50,000 deaths.
