Association between night/after-hours surgery and mortality: a systematic review and meta-analysis

2020

Abstract Background The association between night/after-hours surgery and patients' mortality is unclear. Methods The protocol of this systematic review was registered in PROSPERO (CRD42019128534). We searched Medline, PubMed, and EMBASE from inception until August 29, 2019 for studies examining an association between timing of surgical procedures (time of anaesthesia induction or surgery start) and mortality (within 30 days or in-hospital) in adult patients. Studies reporting patients' mortality after surgery performed during the weekend only were excluded. All analyses were done using the random-effects model. Results We included 40 observational studies (36 retrospective and four prospec…

Suture needles in Oral Surgery: Alterations depending on the type and number of sutures

2011

This study examined whether the number and type of sutures used in oral surgery influence two ad hoc variables (incision plane and displaced area), which are two variables related to whether the suture needle is suitable for the task. Seventy-five TB-15 needles were studied, which were used to suture between zero and three mucosa and/subperiosteal sutures, producing 15 groups with 5 needles in each one. The incision plane and displaced area were measured for each group, which are two variables related to how the needle has worn and altered. Statistical treatment was conducted using the Kruskal-Wallis H test to compare multiple values and the Mann-Whitney U test to compare pairs. A multi-sta…

Robot-assisted cervical esophagectomy: first clinical experiences and review of the literature

2020

Summary Pulmonary complications, and especially pneumonia, remain one of the most common complications after esophagectomy for esophageal cancer. These complications are reduced by minimally invasive techniques or by avoiding thoracic access through a transhiatal approach. However, a transhiatal approach does not allow for a full mediastinal lymphadenectomy. A transcervical mediastinal esophagectomy avoids thoracic access, which may contribute to a decrease in pulmonary complications after esophagectomy. In addition, this technique allows for a full mediastinal lymphadenectomy. A number of pioneering studies have been published on this topic. Here, the initial experience is presented as wel…

Endovascular Treatment of Superficial Femoral and Proximal Popliteal Arteries Lesions

2019

Abstract Mechanical stress due to flexion-extension in the femoropopliteal space may cause stent failure via stent fracture and thrombosis. Wire-Interwoven self-expanding Nitinol Stents design partially mimics the reticular structure of native vessels, emphasizing radial strength, flexibility and kink resistance; these stent features can offer more chances for short and long term patency. We have evaluated 5 patients with peripheral artery disease with significant superficial femoral artery or proximal popliteal artery lesions. All patients underwent endovascular therapy with Wire-Interwoven self-expanding Nitinol Stents, with primary focus on stent patency at follow-up visits (1, 6, 12 mon…

U-stitches in microvascular anastomosis in an animal model.

Experimental reimplantation utilizing microvascular anastomosis in animals.

1977

Summary The use of the operating microscope and special microsurgical instruments make it possible to achieve successful anastomosis of blood vessels of less than 1 mm in diameter. Microvascular surgery offers newer possibilities in the transplantation of dermisfat grafts, and has led to an unusually high degree of success in the reimplantation of tissues. This paper describes a technique for microvascular anastomosis in animal experiment, using as a model the reimplantation of a completely amputated rabbit ear. In 10 amputated rabbit ears, the central auricular artery with a diameter of 0.5 mm and the two marginal auricular veins with diameter of 0.5–1.0 mm were microsurgically anastomosed…

Transanal Hemorrhoidal Dearterialization With Doppler Arterial Identification Versus Classic Hemorrhoidectomy: A Retrospective Analysis of 270 Patien…

2019

Purpose: Despite the minimally invasive nature of transanal hemorrhoidal dearterialization (THD) with Doppler arterial identification procedures, hemorrhoidectomy is still considered the gold standard procedure for hemorrhoidal disease. However, the classical techniques of hemorrhoidectomy have a high rate of postoperative complications. The main purpose of this study is to demonstrate the efficacy and complications of these techniques used for grades II and III hemorrhoids.Methods: A retrospective (case-control) study was carried out from January 2009 to May 2014, and all patients undergoing surgical procedures for hemorrhoidal disease in two French clinics were considered. Application of …

Computer-aided navigation in neurosurgery

2003

The article comprises three main parts: a historical review on navigation, the mathematical basics for calculation and the clinical applications of navigation devices. Main historical steps are described from the first idea till the realisation of the frame-based and frameless navigation devices including robots. In particular the idea of robots can be traced back to the Iliad of Homer, the first testimony of European literature over 2500 years ago. In the second part the mathematical calculation of the mapping between the navigation and the image space is demonstrated, including different registration modalities and error estimations. The error of the navigation has to be divided into the …
