EurekAlert! -- A research article to be published on January 7 , 2010 in the World Journal of Gastroenterology addresses this question. In this prospective randomized clinical trial, the authors examined if acupuncture could prevent prolonged postoperative ileus (PPOI) after intraperitoneal surgery among patients with colon cancer in Shanghai, China. Acupuncture did not prevent PPOI in this population. Subset analyses in patients who developed PPOI also suggested acupuncture was not useful in this setting to treat PPOI once it developed.
