Objectives: Covering open wounds with a polyglycolic acid (PGA) sheet using fibrin glue after resection of oral mucosal lesions is reportedly useful. We focused on clinical complications of this procedure: development of marked granuloma-like neoplasm (GLN) and abnormal postoperative bleeding (APB) on the resected region.
Study Design: The characteristics of 100 cases with PGA sheet application after the resection of oral mucosal lesion were examined retrospectively by the medical records and/or oral photographs at our department between 2010 and 2016.
Results: Our retrospective analysis identified included 8 cases of GLN development and 7 cases of APB. There was a significantly higher risk of GLN development when the PGA sheet was applied to the raw surface of the tongue. There were no immediate APBs, but 4 APBs occurred several hours after surgery. All APB cases involved the tongue.
Conclusions: Both GLNs and APBs are minor complications. Although all cases of GLNs did not involve the recurrence of a tumor, follow-up with incisional or excisional biopsy should be performed. APB in the oral cavity induced by the PGA sheet peeling due to fluctuating adhesive force of the PGA sheets and fibrin glue can sometimes induce life-threatening events.

Background: Impairment of the visceral pleura following thoracic surgery often leads to air leaks and intrathoracic adhesions. For preventing such complications, mesothelial cell proliferation at the pleural defects can be effective. To develop new materials for pleural defects restoration, we constructed a hybrid artificial pleural tissue (H-APLT) combining polyglycolic acid (PGA) nanofiber sheets with a three-dimensional culture of mesothelial cells and fibroblasts and evaluated its therapeutic efficacy in a rat pleural defect model.

Absorbable biomaterials as adjuvant therapy after thoracoscopy are sometimes used in clinical scenarios. With the prevalence of enhanced rapid recovery in thoracic surgery, drainless video-assisted thoracoscopy surgery (VATS) is often adopted by thoracic surgeons. Here, we discuss utilizing an absorbable biomaterial, Neoveil (Polyglycolic Acid sheet), for drainless VATS to treat early lung cancer.

Purpose: A hamster adhesion model was used to investigate the mechanism by which polyglycolic acid (PGA) sheets reinforce the surgical site through the acceleration of postoperative adhesion formation.
Methods: After receiving electrocautery burns on the inside of the abdominal wall, the hamsters were divided into the PGA group (a PGA sheet was placed on the burned area) and a non-treated group (a PGA sheet was not placed). The degree of adhesion was evaluated at 3, 14, 28, and 56 days after burn injury, and the mRNA levels of myeloperoxidase (MPO), tumor necrosis factor (TNF)-α, and transforming growth factor (TGF)-β1 at the surgical sites were measured.

Anastomotic-leakage incidence has been reported to be reduced on using polyglycolic acid (PGA) sheets as reinforcing materials; however, there is insufficient evidence regarding the reinforcement mechanism. Therefore, we investigated effects of PGA sheets on gastrointestinal anastomoses in rats. In the first approach, five rats underwent laparotomy; the PGA sheet was pasted onto the normal cecal wall.

Article Synopsis
- After surgery for intradural lesions, it's crucial to reconstruct the dura effectively to prevent serious complications like cerebrospinal fluid (CSF) leakage.
- This study compares the effectiveness of two materials—fibrin-coated porous collagen matrix and fibrin-coated polyglycolic acid (PGA) sheets—in preventing CSF leakage during spinal surgery.
- Results showed that the porous collagen matrix significantly reduced the occurrence of CSF leakage (0%) compared to the PGA sheet group (5%), highlighting its potential superiority in surgical applications.
