title: [The role of pneumoperitoneum and the "chimney effect" on the development of port site metastasis. A new experimental animal model using Furka's spleen tissue suspension].
abstract: Following the introduction of laparoscopic cholecystectomy, laparoscopic technology has been applied in many other fields of surgery, including surgery for malignancies, even before prospective, randomised trials were available. Many authors observed development of port site metastases following laparoscopic surgery in malignancies (1-2%). The studies report about the pathomechanism of the development of port site metastasis, some describe the role of pneumoperitoneum. We developed a new model to show the role of pneumoperitoneum and the "chimney effect" on the development of port site metastasis, using a large experimental animal with a suspension of its own spleen tissue. On follow up histology viable spleen tissue was found between the layers of the trocar incisions.
