Methods: A total of 240 cases were randomly allocated into an observation group and a control group according to their admission sequence, 120 in each group. Cases in the observation group were treated with conventional care, glycerol enema and heat sensitive moxibustion, whereas cases in the control group were only treated with conventional care and glycerol enema. Then the passage of gas by anus within 24 h and improvement of abdominal distension were observed in both groups. Results: There were statistical differences in the emergence time of bowel sounds and the initial passage of gas by anus between the two groups(both P<0.05). The therapeutic effect in the observation group was better than that in the control group(P<0.05). Conclusion: Heat-sensitive moxibustion has reliable effect for abdominal distension following laparoscopic cholecystectomy.展开更多
