INTRODUCTION: New biological materials are needed for specific applications in reconstructive bowel surgery and for the prevention of adhesion formation. Amniotic membranes (AMs) are assumed to have a number of unique characteristics that enhance the ingrowth of the surrounding tissue. The aim of the present study was to provide proof of these qualities in a xenograft model. MATERIALS AND METHODS: A multilayer human AM (HAM) was applied to repair defined colon wall defects in Sprague-Dawley rats (n = 18)...

A clear visualization of the operative field is of critical importance in endoscopic surgery. During surgery the endoscope lens can get fouled by body fluids (eg, blood), ground substance, rinsing fluid, bone dust, or smoke plumes, resulting in visual impairment. As a result, surgeons spend part of the procedure on intermittent cleaning of the endoscope lens. Current cleaning methods that rely on manual wiping or a lens irrigation system are still far from ideal, leading to longer procedure times, dirtying of the surgical site, and reduced visual acuity, potentially reducing patient safety...

Peritoneal dialysis (PD) is an effective renal replacement therapy for the treatment of end-stage renal disease. Patients on PD undergoing abdominal open surgery often fail to resume PD. Laparoscopic surgery has recently become a serious alternative to open surgery in patients on PD to treat different abdominal pathologies. However, only a few studies have reported successful procedures without Tenckhoff catheter removal. The aim of this review is to describe how a laparoscopic technique can allow PD patients to deal with abdominal surgery without shifting to hemodialysis...

Pavlos Ioannou performed an innovative surgical operation for breast cancer in Vienna University Hospital in 1861. A few years later, after his return to Greece, an operation performed on his closest friend's child, which led to fatal complications, led him to retire from surgical practice. William Halsted travelled to Europe in order to master European surgery, including at Vienna University, and about 20 years later he published his famous method for radical mastectomy, which appears to be identical to Ioannou's operation...

Professor Sergei Semjonovic Golovin (1866-1931) is considered as one of the founders of ophthalmology in Russia. He received a worldwide reputation thanks to his achievements in ocular surgery and pathology. He introduced new surgical techniques such as Golovin's operation (Exenteratio orbitosinualis), Golovin's osteoplastic frontal sinus operation, ligation of orbital veins, and opticociliary neurectomy. He also introduced his "cytotoxic theory" to interpret sympathetic ophthalmia. He was a reputable professor of ophthalmology...

BACKGROUND: Fluorescence cholangiography using indocyanine green (ICG) can enhance orientation of bile duct anatomy during laparoscopic cholecystectomy. To ensure clear discrimination between bile ducts and liver, the fluorescence ratio between both should be sufficient. This ratio is influenced by the ICG dose and timing of fluorescence imaging. We first systematically identified all strategies for fluorescence cholangiography. Second, we aimed to optimize the dose of ICG and dosing time in a prospective clinical trial...

The benefits of electrosurgery have been acknowledged since the early 1920s, and nowadays more than 80% of surgical procedures involve devices that apply energy to tissues. Despite its widespread use, it is currently unknown how the operator's choices with regard to instrument selection and application technique are related to complications. As such, the manner in which electrosurgery is applied can have a serious influence on the outcome of the procedure and the well-being of patients. The aim of this study is to investigate the variety of differences in usage of electrosurgical devices...

PURPOSE: The use of active medical devices in clinical routine should be as safe and efficient as possible. Usability tests (UTs) help improve these aspects of medical devices during their development, but UTs can be of use for hospitals even after a product has been launched. The present pilot study examines the costs and possible benefits of UT for hospitals before buying new medical devices for theatre. METHODS: Two active medical devices with different complexity were tested in a standardized UT and a cost-benefit analysis was carried out assuming a different device bought at the same price with a higher usability could increase the efficiency of task solving and due to that save valuable theatre time...

Prosthetic reinforcement reduces the recurrence rate of large paraesophageal hernias (PEH), but the use of synthetic or biosynthetic mesh in the repair remains controversial. PEH repair has reported recurrence rates of 12% to 42%, and primary repair of PEH by suture closure under tension is at high risk of disruption. Synthetic mesh use in large PEH repair has shown to reduce recurrence but can lead to problems including mesh erosion, ulceration, stricture, and dysphagia. The objective of this study was to examine the long-term safety and efficacy of Strattice biologic mesh, a porcine acellular dermal matrix, in crural reinforcement of laparoscopic large PEH repair...

Irreversible electroporation (IRE) is a nonthermal ablation modality employed to induce in situ tissue-cell death. This study sought to evaluate the efficacy of a novel high-frequency IRE (H-FIRE) system to perform hepatic ablations across, or adjacent to, critical vascular and biliary structures. Using ultrasound guidance H-FIRE electrodes were placed across, or adjacent to, portal pedicels, hepatic veins, or the gall bladder in a porcine model. H-FIRE pulses were delivered (2250 V, 2-5-2 pulse configuration) in the absence of cardiac synchronization or intraoperative paralytics...

BACKGROUND: Compression anastomosis has been recently abandoned because of a nonsuperiority compared to stapling anastomosis. Nonremoval of the rings has frequently been reported and this technique does not support a routine use. The aim of this experimental study was to assess the feasibility of anastomosis using compression with a device consisting of fragmented rings. METHODS: A new compression device, the "Anastocom," was compared to standard double-stapled colocolonic anastomosis in 2 groups of 8 pigs...
