Patients with distal esophageal pathology such as perforation, trachea-esophageal fistulae, and/ or obstructing gastroesophageal junction tumor present a challenging situation in terms of feeding access where an esophageal stent is placed across the gastroesophageal junction. In order to allow simultaneous gastric decompression and post-pyloric feeds without significant reflux up through the stent, a gastrojejunostomy (GJ) tube is a viable option. We hereby describe a hybrid approach to placing these GJ tubes in this cohort of patients using simultaneous laparoscopy, endoscopy, and fluoroscopy with minimal manipulation of the stent itself...

BACKGROUND: Perforation of pulmonary valve using radiofrequency ablation in pulmonary atresia with intact ventricular septum (PA IVS) is a treatment of choice. However, significant cost of the equipment limits its utility, especially in the developing economies. OBJECTIVE: To assess the feasibility, safety, and efficacy of perforation of pulmonary valve using chronic total occlusion (CTO) wires in patients with PA IVS as an alternative to radiofrequency ablation...

Implants for controlled drug delivery can be very helpful to improve the therapeutic efficacy of a medical treatment, and at the same time reduce the risk of toxic side effects. In this article, four different strategies are exemplarily presented: hybrid bone substitutes combining hydroxyapatite and chitosan hydrogels; vascular stents coated with a bio-inspired polymer; cochlear implants for local dexamethasone delivery; and in-situ forming implants for periodontitis treatment. But this is only a restricted selection, and numerous other approaches and applications based on implants releasing a drug (or a combination of drugs) exist...

A surface directly connects the bulk of a material to its surroundings. The ability to dynamically regulate the surface without affecting the bulk of a material holds great potential for new applications. The purpose of this work was to demonstrate that the surface can be dynamically changed using nanoparticles and oligonucleotides (ODNs) in a reversible and reiterative manner. A dual-functional nanogel was synthesized as the model of nanoparticles using miniemulsion polymerization and click chemistry. The nanogel can not only adsorb drugs for sustained drug release but also bind a surface functionalized with complementary ODNs...

Thoracoabdominal aortic aneurysm (TAAA) is a complicated aortic disease. Most treatments for other aortic aneurysms have already shifted from conventional open surgery to endovascular operation; but for TAAA, open surgery remains the gold standard treatment. Several alternative treatments such as hybrid operation as well as endovascular techniques are utilized for the treatment of TAAA. Some of the procedures combine off-the-shelf devices such as the chimney procedure. Some other procedures required custom-made specialized stent grafts...

Combined intravascular ultrasound and photoacoustic imaging (IVUS/IVPA) is an emerging hybrid modality being explored as a means of improving the characterization of atherosclerotic plaque anatomical and compositional features. While initial demonstrations of the technique have been encouraging, they have been limited by catheter rotation and data acquisition, displaying and processing rates on the order of several seconds per frame as well as the use of off-line image processing. Herein, we present a complete IVUS/IVPA imaging system and method capable of real-time IVUS/IVPA imaging, with online data acquisition, image processing and display of both IVUS and IVPA images...

A 42-year-old man experienced a complex aortic arch aneurysm rupture. He had previously undergone an operation for type A dissection and had extremely poor cardiac performance as well as deep sternal infection after the first procedure. The conventional open repair was considered to be a high risk for this patient. We therefore performed an alternative hybrid aortic procedure. The supraarch vessels were perfused through an extraanatomic bypass from an unusual and remote route, namely, the abdominal aorta. Then, stent grafts were implanted in the previously replaced aortic prostheses to exclude the aortic aneurysm...

Circulation arrest is widely used during total aortic arch replacement. However, the conventional procedures have high morbidity and mortality. We modified the hybrid procedure by optimizing the sequence of anastomosis between the graft and aorta. As a result, the time of extracorporeal circulation was obviously shortened, and cardiac arrest was needed only during the two anastomoses of the aorta with aorta graft main body. In addition, both circulation arrest and deep hypothermia were avoided. Leakage was also prevented by creating a lengthened sealing zone for stent graft deployment...

During the past decade, a hybrid procedure has emerged and dramatically evolved as an alternative stage I palliation to the conventional Norwood procedure in neonates with hypoplastic left heart syndrome (HLHS). The hybrid approach avoids the need for cardiopulmonary bypass (CPB) utilizing stenting of the arterial duct and bilateral pulmonary artery banding. Cerebral and coronary perfusion pressure is maintained, and the pulmonary vasculature is protected from higher systemic pressure. Elimination of risks associated with CPB gains vital time to stabilize the patient and correct coexisting noncardiac anomalies and allows growth in preparation for the later stages of the Fontan pathway...

Najjia N Mahmoud, Elijah W Riddle
Recent guidelines recommend an individualized approach to recurrent uncomplicated diverticulitis, reflecting research showing that non-operative treatment is safe. Thus, the majority of operations for diverticulitis in the future may be for complicated indications. A laparoscopic approach may be used for both acute and chronic complicated diverticulitis in appropriate patients, as described in the American and European guidelines. However, a safe approach to minimally invasive surgery requires recognition when conditions deteriorate or are not suited to laparoscopy as well as knowledge of a variety of technical maneuvers that elucidate difficult anatomy and facilitate resection...

Interventional cardiac catheterization has a major place in the management of congenital heart disease. Since the Rashkind atrioseptostomy in mid-1960s, many techniques have been developed. For some, it is necessary to close a cardiac or extracardiac shunt using occluder (double disc system, plug, coil…): closure of atrial septal defect, ventricular septal defect or patent arterial duct. For others, it is necessary to treat a valvular or vascular stenosis using a balloon catheter: dilatation of the pulmonary or the aortic valve, dilatation of aortic coarctation...
