    Consecutive, Bilateral Obturator Hernia in a Single Case
    (2023) Aydin, H. O.; Soy, E. H. A.; Avci, T.; Tezcaner, T.; Yildirim, S.
    Obturator hernia (OH) is a rare pelvic hernia. It is difficult to make an early diagnosis due to the absence of a palpable mass, so it has a high morbidity and mortality rate, and there is delay in surgery. Here, in this report, we present a case of bilateral OH diagnosed at different times. Our report is meaningful as it reveals consecutive OH in a single case. An 87-year old, female patient admitted to emergency with intestinal obstruction findings. Right obturator herniation was seen in a computed tomography (CT) scan, then she underwent urgent surgery. After 2 months, she admitted with left thigh pain. With these findings, CT scans confirmed left OH. In an elderly, skinny, female patient with non-specific bowel obstruction symptoms and medial thigh pain, OH should be considered. Early and rapid radiologic evaluation, followed by surgery, is essential for successful management of OH.

    Multilayer fibroin/chitosan oligosaccharide lactate and pullulan immunomodulatory patch for treatment of hernia and prevention of intraperitoneal adhesion
    (2021) Akbaba, S.; Atila, D.; Keskin, D.; Tezcaner, T.; 0000-0002-3641-8674; 33966830; AAD-9865-2021
    This study aims to develop a novel intraperitoneal two- or three-layered patch with immunomodulatory property for treatment of hernia, regeneration of abdominal wall and prevention of intraperitoneal adhesions. Polypropylene (PP) mesh, middle layer, was intended to provide mechanical support whereas pullulan (PUL) hydrogel coating layer was designed to prevent intraperitoneal adhesions. Fibroin/chitosan oligosaccharide lactate (F/COS) layer electrospun on one side of pullulan was chosen for immunomodulation and abdominal wall regeneration. Physical and mechanical properties and regenerative capacity of intraperitoneal patches were determined. Immunomodulatory property of electrospun layer and whole patch was studied by determining nitric oxide amount produced by RAW 264.7 macrophages. 25 % (w/v) PUL hydrogel and F/COS with 90:10 (w/ w) ratio yielded optimal results. Here, we report that fabricated intraperitoneal patches successfully prevented cell adhesion on one side and increased cell viability and proliferation on other side, along with immunomodulation, in vitro.
