title: Transcutaneous electric acupoint stimulation at Jiaji points reduce abdominal pain after colonoscopy: a randomized controlled trial.
abstract: BACKGROUND
  Transcutaneous electric acupoint stimulation (TEAS) at Jiaji acupuncture points has therapeutic potential for relieving viscera pain and opioid-related side effects. This prospective, randomized, triple-blinded, placebo-controlled trial was to investigate the efficacy of TEAS on abdominal pain after colonoscopy.
  
  
  METHODS
  Consecutive outpatients with American Society of Anesthesiologists (ASA) physical status I or II underwent selective colonoscopy were randomly assigned into two groups for either TEAS or sham pretreatment. The primary outcomes were the incidence of abdominal pain after colonoscopy. The secondary outcomes included the incidence of abdominal distension, postoperative nausea and vomiting (PONV), duration of PACU stay, and patient's satisfaction and acceptance.
  
  
  RESULTS
  Among the 229 patients analyzed, fewer occurrence of post-procedural abdominal pain (11.4% vs 25.2%, P = 0.007) and distension (1.8% vs 7.8%, P = 0.032) were observed in TEAS group, when compared with the sham group. The duration of PACU stay was significant shortened in TEAS group (P < 0.001). Meanwhile, patients' satisfaction score to medical service was higher (P < 0.001), and their acceptance to colonoscopy was improved (P = 0.011).
  
  
  CONCLUSIONS
  Pretreatment with TEAS can reduce post-procedural discomfort, provide more efficient medical resources utilization, and improved patient's satisfaction and colonoscopy acceptance.
