Development of a novel multichannel port (x-Gate®) for reduced port surgery and its initial clinical results

Background: In order to reduce clashing between the instruments during single-incision endoscopic surgery or reduced port surgery we have developed a new multichannel port with wider distance between the channels. Material and methods: We used the newly developed multichannel port (x-Gate (R)) in 34 patients undergoing a variety of reduced port surgery procedures. The operation records of these patients were reviewed. Results: Overall performance of x-Gate (R) was sufficient in the clinical experience. There have been no complications attributed to x-Gate (R). We found that with the x-Gate (R) the conflicts among the forceps have been drastically improved compared with other multi-channel ports we had used before, which had a shorter distance between the channels.
