TITLE: Development of a New Device for Displacement of the Small Intestine in Laparoscopic Rectosigmoid Surgery

Objective: One problem in laparoscopic rectosigmoid surgery is that the surgical field is interrupted by the small intestine. Therefore, a sponge that could be inserted through a port was prepared with a dry compatible material, expanded while in the abdominal cavity, and it was then determined whether the expanded sponge could secure the surgical field by displacing the small intestine.

Methods: The special sponge was shaped into a slender bar (250mm x 8mm x 8mm) by compression. A living pig was placed in a head-down position while under general anesthesia. Then, the sponge was inserted from a port into the abdominal cavity and was positioned to cover the root of the mesentery. Enough physiological saline was sprayed to swell the sponge and displace the small intestine. The body was returned to a horizontal position, and the descending degree of the small intestine was evaluated.

Results: The sponge was expanded to a size of 270mm x 8mm x 72mm by spraying physiological saline on it, and the small intestine did not descend into the pelvic cavity even if the operating table was returned to a horizontal position. Rectal low anterior resection could be completed keeping a horizontal position, and the sponge was removed from a small 4-cm long laparotomy wound that was created to take a sample.

Conclusion: This sponge is considered useful to secure the surgical field without an extreme head-down position in laparoscopic rectosigmoid surgery.
