OneShot-M: A New Device for Close Laparoscopy Pneumoperitoneum

Abstract

INTRODUCTION: The induction of pneumoperitoneum is the first and most critical phase of laparoscopy, due to the significant risk of serious vascular and visceral complications. The closed technique for the creation of pneumoperitoneum could lead to several surgical complications. The present study aimed to overcome the complications associated with the insertion of Veress needle, improving its use, and facilitating the rapid creation of pneumoperitoneum. METHODS: Thirty large white female pigs were enrolled in our study. A common plunger was modified in order to allow the passage of a 15-cm long Veress needle. This method was applied to 26 laparoscopic procedures (26 pigs) of several specialist branches. RESULTS: OneShot-M close laparoscopy pneumoperitoneum creation device allowed us to obtain pneumoperitoneum quickly in all attempts, without any intraoperative and postoperative complications related to the use of the Veress needle. CONCLUSION: The use of the proposed device showed an induction time as quick as the standard laparoscopic closed abdominal entry. The patented device is cheap and allows a safe abdominal entry. In addition, abdominal entry is much faster than the classic open technique.
