Background: Surgical correction of tracheal defects is a complex procedure when the gold standard treatment with primary end-to-end anastomosis is not possible. An alternative treatment may be the use of porcine small intestinal submucosa (SIS). It has been used as graft material for bioengineering applications and to promote tissue regeneration. The aim of this study was to evaluate whether SIS grafts improved tracheal tissue regeneration in a rabbit model of experimental tracheostomy...

OBJECTIVE: The world's smallest calibre "microbiotube" vascular graft was recently developed, with an inner diameter of 0.6 mm. It was formed using in-body tissue architecture (iBTA) and has a high degree of patency and capacity for regeneration in the acute phase, 1 month after implantation. This consecutive study investigated the compatibility and stability of microbiotubes in the chronic phase of implantation for 12 months for potential application in microsurgery. METHODS: This was an in vivo experimental study...

BACKGROUND: Previous work has demonstrated that anastomotic leak can be caused by collagenolytic bacteria such as Enterococcus faecalis via an effect on wound collagen. In humans, E. faecalis is the organism cultured most commonly from a leaking anastomosis, and is not routinely eliminated by standard oral or intravenous antibiotics. Novel strategies are needed to contain the virulence of this pathogen when present on anastomotic tissues. METHODS: Polyphosphorylated polymer ABA-PEG20k-Pi20 was tested in mice for its ability to prevent anastomotic leak caused by collagenolytic E...

Despite advances in drug therapy, pulmonary hypertension-particularly arterial hypertension (PAH)-remains a fatal disease. Untreatable right heart failure (RHF) from PAH eventually ensues and remains a significant cause of death in these patients. Lowering pulmonary input impedance with different PAH-specific drugs is the obvious therapeutic target in RHF due to chronically increased afterload. However, potential clinical gain can also be expected from attempts to unload the right heart and increase systemic output...

The corneal micropocket angiogenesis assay is an experimental protocol for studying vessel network formation, or neovascularization, in vivo. The assay is attractive due to the ease with which the developing vessel network can be observed in the same animal over time. Measurements from the assay have been used in combination with mathematical modeling to gain insights into the mechanisms of angiogenesis. While previous modeling studies have adopted planar domains to represent the assay, the hemispherical shape of the cornea and asymmetric positioning of the angiogenic source can be seen to affect vascular patterning in experimental images...

OBJECTIVES: Nerve transfer has been developed to restore partial function after serious nerve injuries, for example, restoring bladder control after spinal cord injury (SCI). Our aim here was to establish a preclinical proof-of-concept model using nerve transfer for restoring anorectal function after SCI. SETTING: We used laminectomy to model SCI, and bilateral spinal ventral and dorsal nerve root anastomosis to re-establish connectivity to the anorectal musculature...

Lymphaticovenous anastomosis is one of the main surgical treatments nowadays for alleviating lymphedema. A successful lymphaticovenous anastomosis relies on being able to identify "functional" lymphatic collecting vessels that are still capable of transporting lymph, and a nearby vein that is, ideally, reflux-free. This is a retrospective study. A total of 28 lymphedema patients were enrolled from October of 2016 to March of 2017 in Kaohsiung Chang Gung Hospital, Kaohsiung, Taiwan. A noninvasive vein visualizer was used to preselect reflux-free veins for lymphaticovenous anastomosis from five female patients...

BACKGROUND:  Modified multivisceral transplantation (MMVTx) refers to the use of a graft that includes all abdominal organs except the liver. The use of this type of transplant in children and adults expanded over the last years with good results. However, long-term survival in experimental models has not been reported. Our aim is to describe in detail some technical modifications of MMVTx to obtain long-term survival. MATERIALS AND METHODS:  Syngeneic (Lewis-Lewis) heterotopic MMVTx was performed in 16 male rats (180-250 g)...

BACKGROUND: Colorectal cancer is the fourth most diffuse cause of death in the world and local recurrence is associated with a reduced long-term life expectancy, with a reduced quality of life. Rectal washout at the anastomosis site leads to a statistically significant reduction of local recurrences. METHODS: We developed the idea of a new laparoscopic stapler with an integrated washout system that could decontaminate the rectal stump before resection, without the need to enlarge the standard surgical incision or even to distort the incision site, closing the rectal stump just below the inferior part of the cancer, and then proceeding with the resection and stapling of the distal part of the tumor...

End-stage renal disease is becoming a contemporary global concern with increasing prevalence. The available treatment strategies are limited to dialysis and renal transplantation. However, limited organ supply and autoimmune rejection are the shortcomings that limit widespread application of transplantation. Favorably, regenerative medicine is able to provide acellular natural scaffolds for renal transplantation. Experimental surgeries in animal models are a fundamental step in transplantation research. This video presents a practical method for transplantation of bilateral acellular kidneys in a rat model, which could serve as a key step for further research...

OBJECTIVE Traumatic neuromas may develop after nerve injury at the proximal nerve stump, which can lead to neuropathic pain. These neuromas are often resistant to therapy, and excision of the neuroma frequently leads to recurrence. In this study, the authors present a novel surgical strategy to prevent neuroma formation based on the principle of centro-central anastomosis (CCA), but rather than directly connecting the nerve ends to an autograft, they created a loop using a 3D-printed polyethylene Y-shaped conduit with an autograft in the distal outlets...

BACKGROUND: Classic hypoglossal-facial nerve anastomosis inevitably causes hemitongue atrophy and dysfunction. Thus, many variants have been developed to reduce tongue-related morbidities. A comparative study concerning these techniques was conducted in rats to systematically evaluate long-term functional and histological outcomes of the recipient and donor systems. METHODS: Rats (8 per group) were treated by end-to-end neurorrhaphy (EEN), EEN using the hemi-sectioned and longitudinally splitted donor nerve (EEN-Hemi), and end-to-side neurorrhaphy through a perineurial window (ESN-PW) or 30-40% partial neurotomy (ESN-PN)...
