High-definition imaging in endoscopic transsphenoidal pituitary surgery.
2011
Background The transsphenoidal approach to sellar lesions has evolved enormously since its first description in the early 20th century. Endoscopic surgical strategies have become an integral part of the surgical armamentarium. More recently, high-definition (HD) digital cameras with better image resolution were introduced, although their value for the surgical procedure remains equivocal. The purpose of this study was to compare the image quality of a standard-definition (SD) camera with a new HD camera. Methods A transsphenoidal pituitary adenomectomy was recorded simultaneously in HD and SD resolution. Eight experienced neurosurgeons were asked to identify predefined as well as not predef…
Minimally invasive video-assisted thyroidectomy: four-year experience of a single team in a General Surgery Unit.
2013
Minimally invasive video-assisted thyroidectomy (MIVAT) is a surgical technique that has showed increasingly good results, particularly in endocrine surgery centers. The aim of this prospective, non-randomized study was to evaluate feasibility, advantages and critical aspects of MIVAT in a general surgery unit.Two hundred twenty-four patients underwent total thyroidectomy for benign thyroid disease from May, 2008 to April, 2011. They were divided into two groups: one underwent conventional thyroidectomy (CT), and the other underwent MIVAT. The inclusion criteria were thyroid volume ≤35 mL and main nodule size ≤35 mm. For each patient, socio-demographic variables, hospitalization data and ou…
A multicentric randomized study comparing two techniques of magnification assisted loop excision of high-grade cervical intraepithelial neoplasia: vi…
2013
Purpose: To compare loop excisions of cervical intraepithelial neoplasia grade 2 or worse (CIN 2+) under video exoscopy, or colposcopic guidance, with respect to safety and effectiveness. Methods: Prospective multicentric randomized trial of 300 patients, undergoing loop excision for CIN 2+ either under video exoscopy (group A) or colposcope (group B) guidance. Intra- and post-operative complications, resection margins, and removed cervical volume in both groups were evaluated. Results: 19.3% of patients in video exoscopy group and 15.5% in colposcopy group (p = 0.67) had transformation zone (TZ) 3. 45/151 (29.8%) of group A patients and 48/149 (32.2%) of group B patients underwent top-hat …
High-Definition Imaging in Spinal Neuroendoscopy
2010
BACKGROUND Spinal endoscopy is still under controversial discussion. An often acclaimed critic is the poor endoscopic image quality in comparison with the microscope. Since high-definition digital cameras have recently been introduced into spinal neuroendoscopy, the aim of the current study is to examine whether superior image quality has a relevant impact on intraoperativen orientation. MATERIAL AND METHODS A lumbar endoscopic discectomy was recorded simultaneously in High-Definition resolution (HD) and Standard-Definition resolution (SD). 10 experienced spinal surgeons were asked to identify predefined as well as not predefined anatomic structures in HD and SD resolution. Additionally, th…
Work-related upper limb musculoskeletal disorders in paediatric laparoscopic surgery. A multicenter survey.
2013
Abstract Background Surgeons are at risk for developing work-related musculoskeletal symptoms (WMS). The present study aims to examine the physical factors and their association with WMS among pediatric laparoscopic surgeons. Methods A questionnaire consisting of 21 questions was created and mailed to 25 pediatric laparoscopic surgeons (LG). 23/25 surgeons (92%) completed the survey. The questionnaire was analyzed and then split into 2 groups. Group 1 (LG1) included surgeons with greater laparoscopic experience, and group 2 (LG2) included surgeons with less important laparoscopic experience. In addition, we constructed and sent to the same surgeons a similar questionnaire focused on WMS aft…
Long-term results of simplified frozen elephant trunk technique in complicated acute type A aortic dissection: A case-control study.
2016
Aim To describe the long-term experience of a simplified frozen elephant trunk technique (sFETT) used in complicated acute type A aortic dissection (AAAD) treatment. Methods and results Between January 2001 and December 2012, 34 patients (mean age 59.9 ± 11.0 years) with complicated AAAD (DeBakey I) underwent an emergency surgery including sFETT. sFETT consisted in gluing the dissected aortic arch wall layers with gelatine-resorcinol adhesive and video-assisted antegrade open arch aortic stent-graft deployment in the arch or proximal descending aorta. In addition to sFETT, the aortic root was addressed with standard techniques. A 30-day mortality was 14.7% (five patients) due to bleeding (1…
Comparison of minimally invasive parathyroidectomy under local anaesthesia and minimally invasive video-assisted parathyroidectomy for primary hyperp…
2016
Background: Primary hyperparathyroidism (PHPT) origins from a solitary adenoma in 70-95% of cases. Moreover, the advances in methods for localizing an abnormal parathyroid gland made minimally invasive techniques more prominent. This study presents a micro-cost analysis of two parathyroidectomy techniques. Patients and methods: 72 consecutive patients who underwent minimally invasive parathyroidectomy, video-assisted (MIVAP, group A, 52 patients) or "open" under local anaesthesia (OMIP, group B, 20 patients) for PHPT were reviewed. Operating room, consumable, anaesthesia, maintenance costs, equipment depreciation and surgeons/anaesthesiologists fees were evaluated. The patient's satisfactio…
Minimally Invasive Video-Assisted Thyroidectomy: Analysis of Complications From a Systematic Review
2019
Background. Nowadays, minimally invasive video-assisted thyroidectomy (MIVAT) is considered a safe and effective option. However, its complication rate has not been specifically discussed yet. The aim of this systematic review was enrolling a large number of studies to estimate early and late complications (transient and definitive, uni- and bilateral laryngeal nerve palsy; transient and definitive hypocalcemia; cervical hematoma; hypertrophic or keloid scar) of MIVAT compared with conventional technique. Methods. The review was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria in PubMed and Embase. Search terms were “minimally inva…
Comparison between Minimally Invasive Video-Assisted Thyroidectomy and Conventional Thyroidectomy: Is There Any Evidence-Based Information?
2008
The aim of this study was to test the hypothesis that minimally invasive video-assisted thyroidectomy (MIVAT) affords comparable safety and efficacy as to the open conventional surgery in dealing with patients with small thyroid nodules.Randomized controlled trials comparing the MIVAT with open thyroidectomy were ascertained by methodical search using Medline, Embase, Pubmed, and The Cochrane Library. Primary meta-analysis outcomes were adverse events (laryngeal nerve palsy and hypoparathyroidism), and cosmesis and secondary outcomes were operative time, blood loss, and early and late postoperative pain.Operative time was significantly less with open thyroidectomy than with MIVAT, while MIV…
Video-assisted two-stage basilic vein transposition for creation of brachio-basilic arteriovenous fistulae
2012
We report our experience in a mixed minimally-in- vasive technique for the two-stage transposition of basilic vein on a small series of eight patients. The operative tech- nique consisted of a modified endoscopic (1) approach for the two-stage transposition (2). The intervention was performed under Brachial Plexus Block (3).
