A New Device to Prevent Irregular Adsorption of Fatty Tissue While Using an Irrigation-suction Instrument for Laparoscopic Surgery

Abstract

Background:While using an irrigation-suction instrument for laparoscopic surgery, irregular adsorption of fatty tissue may damage the tissue or obstruct continuous sucking. A new device made up of a divided silicone drain tip to prevent irregular adsorption was reported.Materials and Methods:A cigarette-type silicone drain was cut 4 cm in length. It was slipped over the instrument to cover the side holes, leaving 1.0 to 1.5 cm free from the end of the instrument. It was fixed by means of 1-0 silk above the side holes. Finally, the free tip was divided vertically into 4 even pieces like octopus arms.Results:This device could prevent the irregular adsorption of fatty tissue (greater and lesser omentum, or epiploic appendices) and could suck saline, fresh, and coagulated blood almost continuously.Conclusions:This simple and easy device facilitated the prevention of irregular adsorption of fatty tissue while using an irrigation-suction instrument for laparoscopic surgery.

How to Prevent Irregular Adsorption of Fatty Tissue into the Irrigation-Suction Instrument

“…Finally, the free part of the silicone drain was divided vertically into four even pieces like octopus arms. As the instrument attached with the divided silicone drain tip could not be inserted from 5 mm trocar, it was inserted from 12 mm trocar or directly through the EZ Access (Multi channel port, Hakko Co., Ltd., Nagano, Japan) when placed on the abdomen [4]" After our first report in 2015, we used divided silicone drain tip for several laparoscopic surgeries of esophageal hiatal hernia, gastric cancer, colon cancer, rectal prolapse, appendicitis, liver cancer, cholecystolithiasis, and cholecystitis.…”

“…As it was mentioned in the previous report [4], we studied reports on "irrigation-suction instrument" and "irregular adsorption of fatty tissue" in PubMed and Japanese Medical Abstracts Society Web (JMASWeb). There were no paper and only four proceedings of conference in JMASWeb (in Japanese).…”

“…A novel laparoscopic suction device for applying precise aspiration during laparoscopic surgery, sponge-tip suction tube, was reported to prevent suctioning intra-abdominal organs, such as the intestine and omentum in 2008 [3]. We firstly reported the details of a new device made up of a divided silicone drain tip attached to the end of an irrigation-suction instrument to prevent irregular adsorption of fatty tissue in 2015 [4]. Furthermore, novel endoscopic catheter for "Laparoscopy-Like" irrigation and suction inspired by natural orifice translumenal endoscopic surgery (NOTES) was reported to result in no mucosal injuries in the EIS suction in 2016 [5].…”
