Pancreaticobiliary maljunction (PBM) is a congenital malformation in which the pancreatic and bile ducts join anatomically outside the duodenal wall, usually forming an abnormally long common channel. In PBM, since the long common channel defeats the effect of the sphincter of Oddi, pancreatobiliary reflux frequently occurs, resulting in high rates of biliary tract cancers. We present the case of a 68-year-old female with advanced gallbladder cancer concomitant with bile duct cancer associated with PBM without biliary dilatation that had an extremely rare configuration showing a connecting duct without a long common channel...

Retinal vein cannulation is a demanding procedure where therapeutic agents are injected into occluded retina veins. The feasibility of this treatment is limited due to challenges in identifying the moment of venous puncture, achieving cannulation and maintaining it throughout the drug delivery period. In this study, we integrate a force-sensing microneedle with two distinct robotic systems: the handheld micromanipulator Micron, and the cooperatively controlled Steady-Hand Eye Robot (SHER). The sensed tool-to-tissue interaction forces are used to detect venous puncture and extend the robots' standard control schemes with a new position holding mode (PHM) that assists the operator hold the needle position fixed and maintain cannulation for a longer time with less trauma on the vasculature...

BACKGROUND: Vascularized composite allografts, particularly hand and forearm, have limited ischemic tolerance after procurement. In bilateral hand transplantations, this demands a 2 team approach and expedited transfer of the allograft, limiting the recovery to a small geographic area. Ex situ perfusion may be an alternative allograft preservation method to extend allograft survival time. This is a short report of 5 human limbs maintained for 24 hours with ex situ perfusion. METHODS: Upper limbs were procured from brain-dead organ donors...

In recent years, advances in plant breeding were achieved, which potentially led to modified nutritional values of cereal grains. The present study was conducted in order to obtain a broad overview of ruminal digestion kinetics of rye, triticale and barley grains, and to highlight differences between the grain species. In total, 20 genotypes of each grain species were investigated using in situ and in vitro methods. Samples were ground (2 mm), weighed into polyester bags, and incubated in situ 1 to 48 h in three ruminally cannulated lactating dairy cows...

OBJECTIVE: The fenestrated Anaconda endograft (Vascutek/Terumo, Inchinnan, UK) is intended for the treatment of abdominal aortic aneurysms with an insufficient infrarenal landing zone. The endografts are custom-made with use of high-resolution, 1-mm-slice computed tomography angiography images. For every case, a nonsterile prototype and a three-dimensional (3D) model of the patient's aorta are constructed to allow the engineers as well as the physician to test-implant the device and to review the fit of the graft...

Changes in rumen microbiota and in situ degradation kinetics were studied in 12 rumen-cannulated Holstein Friesian dairy cows during the dry period and early lactation. The effect of a rapid (RAP) or gradual (GRAD) postpartum (pp) rate of increase of concentrate allowance was also investigated. Cows were fed for ad libitum intake and had free access to a mixed ration consisting of chopped wheat straw (dry period only), grass silage, corn silage, and soybean meal. Treatment consisted of either a rapid (1.0 kg of dry matter/d; n = 6) or gradual (0...

We developed a new internal fixation method for extra-articular fractures at the base of the proximal phalanx using a headless compression screw to achieve rigid fracture fixation through a relatively easy technique. With the metacarpophalangeal joint of the involved finger flexed, a smooth guide-pin is inserted into the intramedullary canal of the proximal phalanx through the metacarpal head and metacarpophalangeal joint. Insertion tunnels are made over the guide-pin using a cannulated drill. Then, a headless cannulated screw is placed into the proximal phalanx...

The robotic approach to cardiac surgery offers patients numerous potential advantages compared with a traditional sternotomy approach including shorter hospital length of stay, reduced pain, fewer blood transfusions, and a quicker return to normal daily activities. At the same time, robotic cardiac surgery requires that the anesthesiologist employs several subspecialty skillsets in order to provide optimal care for these patients. Multiple different regional anesthesia techniques may be used to improve analgesia, reduce opioid dosages, and facilitate rapid extubation at the conclusion of the case...

Vein location and assessment are essential to improve the success rates for vascular access. However, problems remain with first attempt success rates for peripheral cannulation and locating difficult veins. Practitioners may not be aware of developments in technology and aids to assist in the location and assessment of veins to achieve vascular access. This article provides an overview of two vein location aids that can be used to locate difficult veins: the IV-eye vein imager and the Vacuderm tourniquet. It discusses the patient factors that can increase the difficulty of vein assessment and location, and emphasises the importance of vessel health and preservation, and vein palpation...
