Objectives: In the surgical treatment of acute aortic dissection, tissue glues are widely used to reinforce the adhesion between the dissected aortic layers. A new inflatable balloon device was developed to compress the dissected aortic wall during gluing to increase adhesion between the dissected layers. The present study used an ex vivo experimental animal model to test the hypothesis that this device is effective when gluing the true and false channels of dissected aortas.
Methods: In the ex vivo experimental model, aortic dissection was simulated surgically on 12 fresh bovine aorta samples. In six samples (group I), the inflatable balloon device was inserted into the aorta to reinforce and fuse the dissected layers during gluing. The other six fresh bovine aortic samples (group II) were compressed between the surgeon's fingers during gluing. Aortic samples were evaluated and compared macroscopically and histologically.
Results: In group I, adhesion between the dissected layers was easily achieved during gluing. All false cavities were perfectly closed, with no deleterious effects related to the device. In group II, the adhesion between the dissected layers was not complete and some false cavities remained patent.
Conclusions: The inflatable balloon device can increase the adhesive effect of tissue glues via homogenous compression of the dissected aortic layers. In addition, the balloon can prevent distal embolization of the glue.

Background: This study aimed to investigate the clinical characteristics and esophageal motility of patients with gastric cardia submucosal tumors (SMTs) and the associated changes after endoscopic resection based on high-resolution impedance manometry (HRIM).
Methods: From our electronic database, we identified patients who underwent pre-operative evaluation of gastric cardia SMTs between 2015 and 2023. All patients completed standardized symptom questionnaires and underwent endoscopic ultrasonography and HRIM.

Bone damages in laying hens are of great concern in poultry farming. Besides various risk factors like housing systems or nutrient supply during egg production, it has often been hypothesized that genetically high-performing laying hens may be more prone to bone damages. The relevance of dietary support during the rearing period of pullets for optimal bone development has been little addressed so far.

Background: Interventricular septal dissection is a critical disease characterized by the separation of the intraventricular septum into two layers, forming an intermediate layer with a cystic cavity that communicates with the root of the aorta or ventricle. It has low morbidity and high mortality rates.

To report the cosmetic, clinical, and visual outcomes of a combined surgical approach for treating a corneal/limbal dermoid using excision and a three-layered amniotic membrane graft with fibrin glue. An 18-year-old female presented with impaired vision and ocular discomfort caused by a prominent dome-shaped limbal congenital dermoid on the inferotemporal cornea, resulting in a significant aesthetic concern. A full assessment, including refraction, best-corrected visual acuity (BCVA), corneal topography, aberrometry and anterior segment OCT (AS-OCT) was conducted to plan the surgical approach.
