INTRODUCTION: The Spies™ system (Karl-Storz®) was introduced into digital ureteroscopy to improve endoscopic vision. To date, there is no data to either indicate which of the Spies modalities is better for improving diagnosis and treatment procedures, nor to compare the modalities in terms of image quality. The aim of this study was to evaluate and compare the image quality of five Spies™ modalities (SM) to the standard white light in an in-vitro model. MATERIALS AND METHODS: Two standardized grids and 3 stones of different composition were recorded in white light and the 5SM (Clara, Chroma, Clara+Chroma), Spectra A and B) using 4 standardized aqueous scenarios...

An endometrial biopsy allows for a comprehensive assessment of the uterine environment of a breeding female. Although routine in mares, devices used for endometrial biopsies are impracticable in heifers due to the size and structure of the cervix. This report describes the use of a human bronchoscopy biopsy device (Karl Storz(®) 10366L) for collection of endometrial biopsies in Bos indicus beef heifers. The Storz(®) device is smaller and thinner and enabled the collection of an endometrial biopsy in 86% of heifers (n = 44/51)...

Miniaturized percutaneous nephrolithotomy (mini-PCNL) has increased in popularity in recent years and is now widely used to overcome the therapeutic gap between conventional PCNL and less-invasive procedures such as shock wave lithotripsy (SWL) or flexible ureterorenoscopy (URS) for the treatment of renal stones. However, despite its minimally invasive nature, the superiority in terms of safety, as well as the similar efficacy of mini-PCNL compared to conventional procedures, is still under debate. The aim of this chapter is to present one of the most recent advancements in terms of mini-PCNL: the Karl Storz "minimally invasive PCNL" (MIP)...

Paediatric endoscopic surgery is greatly indebted to Karl Storz for developing paediatric endoscopic instruments. In more recent years, there is an increasing interest in endoscopic surgery in neonates. Now more complex procedures are being performed, although it will take another generation before these will be more generally applied. One of the key factors to success is training. More sophisticated training models are becoming available, allowing practicing in a safe environment before putting the procedure to practice...

BACKGROUND: To avoid bile leakage from the stump of a cystic duct that is closed at edematous and/or involved areas, the decision regarding the location of the resection line during a laparoscopic cholecystectomy for benign lesions extending into the cystic duct is important and requires technical ingenuity. For these situations, we used fluorescent cholangiography. METHODS: Our procedure for single-incision laparoscopic cholecystectomy utilized the SILS-Port, and an additional pair of 5-mm forceps was inserted via an umbilical incision...

As neonatal endotracheal intubation (ETI) is a low-frequency, high-consequence event, it is essential that providers have access to resources to aid in ETI. We sought to determine the impact of video laryngoscopy (VL) with just-in-time training on intubation outcomes over direct laryngoscopy (DL) when performed by neonatal nurses. We conducted a prospective, randomized, crossover study with neonatal nurses employed at a level 2 neonatal intensive care unit (NICU). Nurses performed both DL and VL on a neonatal mannequin using a CMAC (Karl Storz Corp, Tuttlingen, Germany) either with the assistance of the screen (VL) or without (DL)...

INTRODUCTION: The holmium laser has revolutionized the practice of minimally invasive endoscopy for kidney stones. Recently, a novel, rigid handpiece for use in percutaneous nephrolithotomy (PCNL) that couples the holmium laser with suction has been developed. To date, limited data exist regarding the usability and ergonomics of such treatment systems. We thus sought to compare surgeon-rated usability with three different suction laser handpieces in a porcine model. MATERIALS AND METHODS: We performed bilateral reverse PCNL on four female domestic farm pigs...
