The impact of retractor SPONGE-assisted laparoscopic surgery on duration of hospital stay and postoperative complications in patients with colorectal cancer (SPONGE trial): study protocol for a randomized controlled trial

摘要

BackgroundTo achieve an adequate visual working field during laparoscopic colorectal surgery without disturbance of the small intestine, patients are positioned in the Trendelenburg position. This position results in hemodynamic changes that may increase the risk of cardiopulmonary complications and prolonged hospital stay. Recently, an intraoperative retractor sponge was introduced as an alternative to the Trendelenburg position during laparoscopic surgery.The objective of this trial is to study the impact of the use of an intraoperative retractor sponge on the duration of the hospital stay and risk of perioperative complications in patients undergoing laparoscopic surgery for colorectal cancer.
