A model for lymphocyte activation in open versus laparoscopic surgery in colorectal cancer patients in enhanced recovery after surgery (ERAS) protocols

Purpose Given the high mortality and morbidity associated with colon cancer worldwide and the advantages inherent to the use of the laparoscopy technique with respect to open surgery in oncological colorectal surgery, a study was designed to observe and compare the lymphocyte activation model between open surgery (OS) and laparoscopic surgery (LS) for this type of patient as part of an ERAS protocol.
