Method of Performing Transgastric Abdominal Surgery

摘要

A minimally invasive method of performing surgical procedures in the peritoneum is provided. The method includes providing a non-lumened flexible visualization scope, a flexible gastric pressurization tube, and at least one additional flexible manipulating instrument, wherein the scope, tube and the instruments are all discrete from each other and all smaller than 2 mm in diameter. The tools are extended into the esophagus and transgastrically through holes defined by incisions or instrument piercing in the stomach wall into the peritoneum, where they are used to visualize, insufflate and perform a peritoneal surgical procedure. Upon removal of the instruments, the holes are substantially self-sealing, and do not require surgical closure. Optionally, a biocompatible glue can be dispensed at the holes to facilitate closure.
