AbstractCardiothoracic surgery usually causes tissue adhesion on the operation site which increases the risk of complications in the subsequent thoracic surgery including Nuss procedure. Disorders that require cardiothoracic surgery include chest wall deformities such as pectus excavatum, congenital heart diseases, lung diseases such as congenital cystic adenomatiod malformation and bronchopulmonary dysplasia, and congenital diaphragmatic hernia. Recently, we encountered a rare case of combined pectus excavatum and carinatum in a patient with a history of congenital esophageal atresia repair surgery. Commendably, despite tissue adhesion from the previous surgery, a modified Nuss procedure was performed successfully with no complications. We agree that the Nuss procedure is feasible for thoracic deformities in patients with a surgical history of cardiothoracic surgery.

Successful control of massive hemorrhage in deep wounds with irregular shape and low elasticity still remains great challenges in the clinic. As the wound sites are usually at risk of bacterial infection, it is necessary to design an ideal hemostatic agent with rapid hemostasis and excellent antibacterial activity. In this study, we developed a light responsive hemostatic film for effective handling of liver bleeding with promising photodynamic therapy against S. aureus onnear infrared (NIR) irradiation. Based on silk fibroin, the film exhibited desirable biocompatibility and mechanical property as a hemostat tape. Significantly, the film tape achieved excellent tissue adhesion and hemostasis in vivo within 2 min of UV exposure, which would have a great potential as a multifunctional biomedical material in the field of tissue repair such as wound healing, bone repair, and nerve regeneration.

In order to replace traditional wound treatments such as sutures, tissue adhesives with strong wet tissue adhesion and biocompatibility have attracted more attention to the applications of non-invasive wound closure. Herein, inspired by tunicate adhesive protein, a series of 2,3,4-trihydroxybenzaldehyde (TBA)-modified chitosan hydrogels (CS-TBA-Fe) were prepared by easily mixing the solutions of chitosan-FeCl3 and TBA via the Schiff-base reaction and the coordination between Fe3+ and pyrogallol groups. The gelation time was greatly shortened to only several seconds after induced even trace Fe3+. The hydrogel (CS-TBA-Fe) exhibited ~12-fold enhanced wet tissue adhesion strength (60.3 kPa) over the commercial fibrin glue. Meanwhile, the hydrogel also showed robust adhesion to various substrates such as wood, PMMA, and aluminum. The swelling ratio and rheological property can be simply controlled by changing the concentrations of chitosan, TBA, and Fe3+. Moreover, the hydrogel displayed a rapid and highly efficient self-healing ability and an excellent antibacterial activity against E. coli. The overall results show that the CS-TBA-Fe hydrogel with enhanced wet adhesiveness will be a promising tissue adhesive material.

The causes of intestinal obstruction are diverse with tissue adhesion, incarcerated hernia, and large bowel neoplasm being the most common causes. Cancer is not easy to diagnose in patients with a history of intestinal obstruction after the intraperitoneal operation following blunt trauma. Herein, we report the case of a patient who was diagnosed with colon cancer after undergoing adhesiolysis due to intestinal obstruction.
