title: Histological evaluation of pure NOTES - related complications in a survival animal study.
abstract: Considered as an extension of both laparoscopic surgery and interventional endoscopy, natural orifice transluminal endoscopic surgery (NOTES) is emerging as a new alternative of minimal invasive surgery. Literature on the gastrointestinal complications of this novel technique is sparse. The goal of this study was the histopathologic evaluation of postoperative complications in a NOTES experimental animal group. Ten female pigs (Sus scrofus domesticus) underwent transgastric endoscopic oophorectomy and tubectomy followed by gastric closure using OTSC clips. Fourteen days after surgery, the animals were sacrificed. Based on the gross examination during necropsy focused excisional biopsies were performed. Gross and microscopic evidence of gastric ulcer distal to the puncture site and perigastric lymph node abscess were found on one animal. Histological evaluation plays a determinant role in the correct evaluation of postoperative complications of pure NOTES procedures.
