Observation of surgical procedures performed by experts is extremely important for acquisition and improvement of surgical skills. Smart glasses are small computers, which comprise a head-mounted monitor and video camera, and can be connected to the internet. They can be used for remote observation of surgeries by video streaming. Although Google Glass is the most commonly used smart glasses for medical purposes, it is still unavailable commercially and has some limitations. This article reports the use of a different type of smart glasses, InfoLinker, for surgical video streaming...

Three-dimensional (3D) printing is a rapidly advancing technology in the field of surgery. This article reviews its contemporary applications in 3 aspects of surgery, namely, surgical planning, implants and prostheses, and education and training. Three-dimensional printing technology can contribute to surgical planning by depicting precise personalized anatomy and thus a potential improvement in surgical outcome. For implants and prosthesis, the technology might overcome the limitations of conventional methods such as visual discrepancy from the recipient's body and unmatching anatomy...

BACKGROUND: Reoperative neck surgery is technically more demanding because of the presence of scar tissue and distorted anatomy. We aimed to investigate the magnetic probe-guided excision of nonpalpable neck lesions in patients with previously operated neck compartments. METHODS: This study included 9 patients with recurrent/persistent thyroid carcinoma, recurrent/persistent hyperparathyroidism with previously operated neck compartments. The pathologic lesions were localized by ultrasonography, and magnetic tracer (0...

George Critchett (1817-1882) and his son George Anderson Critchett (1845-1925) have influenced the development of ophthalmology and ocular surgery for about a century. They presented new ocular operations such as Critchett's advancement operation, Critchett's corneal staphyloma operation, and Critchett's keratoconus operation, and they invented new surgical instruments such as Critchett's cataract knife, Critchett's scissors, and Critchett's fixation forceps. Both were delicate ocular surgeons managing complex and difficult surgeries...

Indocyanine green (ICG) is increasingly being used in digestive oncology. In colorectal cancer, ICG can be used to detect lymph node metastasis and hepatic metastasis on the surface of the liver. In peritoneal carcinomatosis, it was previously suspected that the diffusion of ICG in the tumor mass was due to the enhanced permeability and retention effect; however, this phenomenon has not been clearly demonstrated. Using bevacizumab, an antibody directed against vascular endothelial growth factor that consequently inhibits neoangiogenesis, we sought to confirm the mode of ICG diffusion...

INTRODUCTION: Anastomotic leak after pancreaticoduodenectomy is the most important cause of postoperative morbidity and mortality. Histological studies of bowel anastomoses have provided valuable insights regarding causes of anastomotic failure. However, this crucial information is lacking for pancreatico-enteric anastomoses. METHODS: Pancreaticoduodenectomy was performed in a porcine model. Animals were survived up to 10 days and then the pancreatico-enteral anastomosis specimen was resected en bloc...

Hippocrates was the first physician to describe in accuracy pleural effusion and pneumonia. To treat empyema thoracis he had introduced a combined method of tracheal intubation with a simultaneously thoracotomy. The surgical incision was used for the pus to be progressively drainaged. If the patient was too weak to eat, he had suggested for nutritional mixtures to be administered through an oral-gastric tube. Thus Hippocrates composed in his operating theatre, an icon similar to modern surgical operations.

Background Complex procedures often have numerous acceptable approaches; it is unclear how surgical fellows choose between techniques. We used pancreaticoduodenectomy as a model to catalogue variability between surgeons and investigate factors that affect fellows' acquisition of techniques. Materials and methods Semistructured interviews and operative note analysis were conducted to determine techniques of 5 attending surgeons, and these data were mapped to identify variations. Identical interviews and questioning were completed with 4 fellowship graduates whose practice includes pancreaticoduodenectomy...

Background Preoperative localization of the parathyroid gland prior to a minimally invasive parathyroidectomy (MIP) is important because of varying locations of the parathyroid gland. Several methods have been described to localize the affected gland. One novel technique is the use of an iodine 125 (I-125) seed as a marker. The aim of this study is to evaluate the feasibility of using an I-125 seed in localizing the diseased parathyroid gland prior to MIP. Materials and methods This is a pilot study of 10 patients performed in the Amphia Hospital, the Netherlands...

OBJECTIVE: Aim of this study was to develop a prototype for an innovative, burr-hole mounted device, for stabilizing endoscopes during intracranial surgery. The objective was an easily maneuverable device, freeing one hand without compromising flexibility and safety. This could avoid the need for a second surgeon or a bulky holder, thus improving coordination. METHODS: The initial concept arose from the observation that intraventricular endoscopy is often performed by 2 surgeons, 1 navigating the endoscope and 1 inserting/handling instruments through the working channel...
