But, current available myocardial prostheses like a Dacron or a pericardium patch neither have a regenerative capacity nor do they actively contribute to the heart’s pump function. This study aimed to show the feasibility of utilizing a vascularized stomach patch for transmural left ventricular wall reconstruction. Methods: A left ventricular transmural myocardial defect was reconstructed by performing transdiaphragmatic autologous transplantation of a vascularized stomach segment in six Lewe minipigs. Three further animals received a conventional Dacron patch as a control treatment. The first 3 animals were followed up for 3 months until planned euthanasia, whereas the observation period for the remaining 3 animals was scheduled 6 months following surgery. Functional assessment of the grafts was carried out via cardiac magnetic resonance tomography and angiography. Physiological remodeling was evaluated histologically and immunohistochemically after heart explantation. Results: Five out of six test animals and all control animals survived the complex surgery and completed the follow-up without clinical complications. One animal died intraoperatively due to excessive bleeding. No animal experienced rupture of the stomach graft. Functional integration of the heterotopically transplanted stomach into the surrounding myocardium was observed. Angiography showed development of connections between the gastric graft vasculature and the coronary system of the host cardiac tissue. Conclusions: The clinical results and the observed physiological integration of gastric grafts into the cardiac structure demonstrate the feasibility of vascularized stomach tissue as myocardial prosthesis. The physiological remodeling indicates a regenerative potential of the graft. Above all, the connection of the gastric vessels with the coronary system constitutes a rationale for the use of vascularized and, therefore, viable stomach tissue for versatile tissue engineering applications.","PeriodicalId":12222,"journal":{"name":"European Surgical Research","volume":"64 2","pages":"177-184"},"PeriodicalIF":1.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9808675/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9672267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Twenty-three consecutive patients (12 men, 11 women, median age 43 yrs) with severe intermittent dysphagia and with hiatal hernia verified by endoscopy were included in the study. They were investigated with esophageal high-resolution manometry (HRM)-, and 24-hr pH- monitoring prior to hiatal hernia repair and at follow-up 6 months after surgery. On both test occasions, the patients were asked to fill in a questionnaire comprising 17 questions on esophageal and chest symptoms (severity grades 0-3). Results: A hiatal hernia was recorded via HRM in all 23 patients prior to surgery and in no one at follow-up. Prior to surgery, all patients had either severe no stenotic dysphagia or frequent retention symptoms in the chest while eating. These two mechanical problems were relieved by surgery (p< 0.0001).
