Experimental surgery

The group intends to develop interdisciplinary projects with special interest in those technologies and methodologies related to abdominal wall surgery and with applicability to other surgeries such as bariatric, hepatic, etc. In particular, the group studies the biomechanical response of the closure of the abdominal wall versus physical and anthropometric factors with the use of measuring instruments designed for this purpose that measure the traction forces of the abdominal wall after the intervention. The objective is to achieve optimum closure of the abdominal wall after an intervention, avoiding tensions and future hernias in the patient.

The Experimental Surgery Group is subdivided into 4 nodes:

  •  Digestive Surgery
  •  Abdominal wall
  •  Endocrine surgery
  •  Thoracic surgery

The Experimental Surgery research group is integrated by surgeons, anesthetists, veterinarians and research and management technicians who work to develop interdisciplinary projects with special interest in those technologies and methodologies related to experimental surgery and the training of health professionals, as well as the development of instruments with applicability to different surgical specialties, such as the abdominal and hepatic walls, among others.

Defined lines of research can currently be identified in the Experimental Surgery group, such as the abdominal wall, led by Dr. Villalobos, who began with the study of the biomechanics of the abdominal wall to find out the physical and anthropometric factors that intervene during the closure and obtain the patent of an instrument that allows measurements to be made to determine the closing forces. Likewise, the group has carried out experimental studies using non-biological glues to fix the meshes to the abdominal wall to surgically repair the eventrations in a porcine experimental model of abdominal wall defect.

Postgraduate training represents a new line of research for the group by conducting studies on the impact of physical or biological clinical simulation on improving the training of professionals in the health sciences. Research in the pig model as an experimental model to study different surgical, diagnostic and therapeutic techniques marks many of the projects that are currently being carried out: anatomy, pain control, lung transplantation, safety in intestinal sutures, etc., with the aim of to be able to obtain experimental models that allow, in the long run, to extrapolate the findings in the human clinic and make a quality translational medicine. The research activities of this group are carried out at the CREBA Center of the IRBLleida.
