Postoperative ileus is a type of bowel dysmotility that may occur after surgery. It is a particularly common occurrence after abdominal surgery and is characterized by bloating due to accumulation of fluid and flatus in the bowel, pain, nausea, vomiting, intolerance to solid food, and delayed passage of flatus and formed stool [1]. The incidence of postoperative ileus among patients who underwent colectomy in United States in the year 2004 was 17.4% [2]. The etiopathogenesis of postoperative ileus is not completely understood; however, surgical manipulation, inflammatory response, and inhibitory neural reflexes are believed to be involved in its causation [3][4][5]. Postoperative ileus accounts for a considerable morbidity and economic burden and has a detrimental effect on patient satisfaction [6][7]. Acupuncture and moxibustion are traditional Chinese medical modalities that have been in use over the past 2000 years. Acupuncture involves piercing of meridian points (acupoints) on the body with needles for therapeutic purposes. Moxibustion involves the application of smoldering moxa cones or sticks directly or indirectly on acupoints. With advances in acupuncture techniques, other methods for therapeutic stimulation of acupoints on the basis of meridian theory have emerged, including auriculotherapy (puncture of certain reactive spots on the auricle), electroacupuncture (EA; a combination of needling and electrostimulation), acupoint injection (AI; injection of certain Chinese and/or Western pharmaceutical agents into acupoints), acupressure (application of pressure over acupoints instead of needles), and catgut embedment at the acupoints (CE; implantation of chromic catgut into acupoints for continuous stimulation).
AbstractIntroduction: Postoperative ileus is a common complication of gastrointestinal surgery, which leads to unsatisfactory outcomes with current therapies. In this review, we examined whether acupoint stimulation after gastrointestinal surgery can help hasten postoperative recovery of the digestive system.
