Abdominal wall massage: effect on colonic function in healthy volunteers and in patients with chronic constipation.
Colonic massage has been claimed to be an efficacious treatment for chronic constipation, though there are no studies to prove this. We therefore investigated the effect of abdominal wall massage on stool frequency and colonic transit time of radiopaque markers in 9 constipated patients (68 +/- 5 years, 5 female, colonic transit greater than 60 h) and in 7 healthy male volunteers (27 +/- 1.2 years) in a control phase and during a three week treatment phase with 9 sessions. Massage was performed as propulsive abdominal wall massage along the presumed course of the colon in an aboral direction (each session 20 min). Stool frequency did not change significantly from control to massage, neither in patients [0.59 +/- 0.08 to 0.68 +/- 0.09 defaecations per day, 95% CI control-massage (-0.23; 0.04)] nor in healthy volunteers 1.11 +/- 0.11 to 0.86 +/- 0.13, 95% CI (-0.01; 0.53)]. Total colonic transit times remained similar during the control and massage phase in patients (126 +/- 19 and 111 +/- 17 h, 95% CI (-11; 41)] and in healthy volunteers (40 +/- 7 and 38 +/- 6 h, 95% CI (-8; 13)]. Even when patients and healthy volunteers were statistically evaluated together, control and massage did not differ significantly. In patients, scores of well-being and stool consistency did not differ significantly during control and massage periods. So colonic massage does not change parameters of colonic function to a clinically relevant degree in healthy volunteers and constipated patients of the investigated age-groups.
