Tissue Approximation

One of the challenging aspects of minimal invasive surgery (MIS) is intracorporal suturing, which can be significantly time-consuming. Therefore, there is a rising need for devices that can facilitate the suturing procedure in MIS. Su2ura Approximation Device (Su2ura Approximation) is a novel device developed to utilize the insertion of anchors threaded with stitches to allow a single action placement of a suture. The objective of this study was to evaluate the long-term safety and tissue approximation of Su2ura Approximation in comparison to Endo Stitch + Surgidac sutures in female domestic pigs. All incision sites were successfully closed by both methods. Firm consolidation within and around the incision site was noted in several animals in both treatment groups, which corresponded histopathologically to islands of ectopic cartilage or bone spicules within the fibrotic scar. These changes reflect heterotopic ossification that is commonly seen in the healing of abdominal operation sites in pigs. No other abnormal findings were observed throughout the study period. In conclusion, the use of Su2ura Approximation under the present experimental conditions revealed no safety concerns.

Abstract Purpose Meshes clearly have improved outcomes for tissue approximation over suture repairs for incisional hernias. A knowledge gap exists as to the surgical complication rate and post-operative outcomes of a mesh rectus diastasis repair with a narrow well-fixed mesh that simultaneously narrows the rectus muscles and closes the widened linea alba. Methods Inclusion criteria for mesh abdominoplasty were patients who (1) underwent a retrorectus planar mesh for repair of rectus diastasis (2) did not have a concurrent incisional hernia and (3) underwent skin tailoring as part of a cosmetic aspect of their care. The primary endpoint was surgical site occurrence (SSO) at any time after surgery as determined with review of their office and hospital medical records. Secondary endpoints included the length and complexity of the return to the operating room for any reason, non-surgical complications, readmission, post-operative recovery, surgical site infection, recurrence/persistence of abdominal wall laxity, and soft tissue revision rates. Results SSO rate was 0% for the 56 patients who underwent this procedure. There were 40 women and 16 men. Superficial infections requiring oral antibiotics were required in three patients. One was a drain site erythema, one was for a superficial stitch abscess, and the third was for a mesh strip knot infection 6 months after the procedure. One patient underwent further tightening of the abdominal wall. Rates of soft tissue revision in the office for improved cosmesis were 23% in women and 6% in men. Conclusion Repair of rectus diastasis with a narrow well-fixed mesh and concurrent skin abdominoplasty is a well-tolerated and reliable procedure with low recurrence and low SSO in the manner described. It is a procedure that works for both female and male pattern rectus diastasis, and has become our procedure of choice for moderate and severe rectus diastasis.

The development of bio-glues is still a challenging task, regarding adhesion on wet surfaces; often, high performance and adaption to complex geometries need to be combined in one material. Here, we report biocompatible adhesives obtained by blending regenerated silk (RS) with a soluble plant-derived polyphenol (i.e., chestnut tannin) that was also used to exfoliate graphite to obtain graphene-based RS/tannin (G-RS/T) composites. The resultant G-RS/T hybrid material exhibited outstanding stretchability (i.e., 400%) and high shear strength (i.e., 180 kPa), superior to that of commercial bio-glues, and showed sealant properties for tissue approximation. Moreover, we showed how such nanocomposites exhibit electromechanical properties that could potentially be used for the realization of green and eco-friendly piezoelectric devices. Finally, we demonstrate the in vitro glue’s biocompatibility and anti-oxidant properties that enable their utilization in clinical applications.
