Purpose: Laparoscopic colorectal surgery is popular. But the safety anesthesia of laparoscopic operation is still unknown. Therefore we investigated respiratory dynamic status during operation of laparoscopic colorectal surgery using a new cellulose sponge (ENDORACTOR®).

Patients and Methods: ENDORACTOR® is a stick type, highly hygroscopic cellulose sponge and absorb about 150ml of water and finally expand flat-like shaped. With the use of this sponge, during laparoscopic rectal or sigmoid colon surgery, we can displace small intestine effectively and keep low-angled head-down position. From December 2009 to April 2010, we experienced 20 patients of laparoscopic rectal or sigmoid colon surgery. So we divided two groups (ENDORACTOR® use or not), and analyzed respiratory dynamic status during the operation retrospectively.

Results: Ten patients used ENDORACTOR® and the other 10 patients did not use it. Both groups did not significantly correlate with age, BMI, operation time, anesthesia time, intraoperative infusion, urinary output and hospital days after operation, but intraoperative parameters such as pressure in the airway and Pet CO2 concentration were significantly increased and pulmonary compliance was significantly decreased after pneumoperitoneum and head down among the ENDORACTOR® non-use group rather than usage group.

Conclusions: ENDORACTOR® has a good chance of minimum amounts of head down and produces a decrease in the perioperative respiratory complication.
