DIGESTIVE & BOWEL DISORDERS

Acumoxa significantly improves IBS symptoms within 4 weeks

A small randomised, sham/placebo-controlled pilot study assessing the effect of individualised TCM acupuncture and moxibustion (Acumoxa) treatment on symptom control of IBS patients found that it showed promise as a treatment. Twenty-nine patients with IBS were randomised to either individualised Acumoxa (treatment group) or sham/placebo Acumoxa (control group). After four weeks of twice-weekly Acumoxa treatment, average daily abdominal pain improved significantly, whereas the control group showed minimal reduction. Intestinal gas, bloating and stool consistency composite scores showed a similar pattern of improvement.

Acupuncture may benefit acid reflux and heartburn

Inappropriate relaxation of the muscular lower oesophageal sphincter (LES) is associated with gastric reflux and heartburn. Now a study has shown that electrical non-needle stimulation of Neiguan P-6 can reduce the rate of LES relaxation by 40%. Fourteen healthy (no heartburn) volunteers were treated either at Neiguan P-6 or a sham point on the hip. A separate study ruled out endorphins or enkephalins as the mechanism of action of the point stimulation by giving the volunteers naloxone, which blocks the effect of these chemicals.

Acupuncture significantly reduces heartburn

If proton pump inhibitors fail to control the symptoms of gastro-oesophageal reflux disease, current standard management is to double the drug dose, despite limited therapeutic gain. An American clinical trial has compared this protocol against use of acupuncture. Thirty patients with classic heartburn symptoms who continued to be symptomatic on standard-dose proton pump inhibitors were enrolled into the study. Patients were randomised to either two acupuncture sessions per week in addition to their proton pump inhibitor regimen, or to doubling the proton pump inhibitor dose, over a period of four weeks. The acupuncture plus proton pump inhibitor group demonstrated a significant decrease in the mean daytime heartburn, night-time heartburn and acid regurgitation scores at the end of treatment when compared with baseline, while the double-dose proton pump inhibitor group did not demonstrate a significant change in their clinical endpoints.

Acupuncture improves quality of life in patients with IBS, Crohn's disease and ulcerative colitis

A systematic review has assessed the evidence for the effectiveness of acupuncture treatment in gastrointestinal diseases. German authors searched Medline-cited literature for controlled clinical trials performed before May 2006, identifying 18 relevant trials that met their inclusion criteria. Of these, only four were robustly designed random controlled trials (RCTs) - two irritable bowel syndrome (IBS) trials and two inflammatory bowel disease (IBD) trials (one for Crohn's disease and one for ulcerative colitis).

In all four trials, quality of life (QoL) was found to improve significantly, independently of whether the acupuncture was real or sham. Real acupuncture was significantly superior to sham acupuncture with regard to disease activity scores in the IBD trials. The authors postulate that psychoneuroimmunologic mechanisms may explain the acupuncture-specific effects leading to clinically relevant improvement of disease activity in Crohn’s and Colitis patients. They also suggest that the efficacy of acupuncture in respect of QoL may be explained by nonspecific treatment effects operating on a psychological and/or physiological level. While recommending further trials, they point out that demystification of the mechanism of acupuncture could be detrimental to its placebo-mediated effects, potentially destroying some of its healing capacity.

Acupuncture offers significant improvements for Ulcerative Colitis (UC) patients within 5 weeks

In a prospective, randomised, controlled clinical trial, 29 patients with mild to moderately active ulcerative colitis were randomly assigned to receive either traditional acupuncture and moxibustion, or sham acupuncture consisting of superficial needling at non-acupuncture points. Patients were treated in 10 sessions over a period of five weeks and followed up for 16 weeks. Colitis Activity Index (CAI) decreased in both acupuncture and sham groups and in both cases these changes were associated with significant improvements in general well-being. Differences in efficacy between traditional acupuncture and sham acupuncture were small and significant only for CAI as the main outcome measure. The authors conclude that both traditional and sham acupuncture seem to offer therapeutic benefit in this condition.

Acupuncture improves patients with Crohn's disease

In a single blind controlled trial of 51 patients with mild to moderately active Crohn’s disease, 27 were randomly assigned to receive traditional acupuncture, and 24 to receive sham acupuncture at non-points. The true acupuncture group showed significantly greater improvements in the Crohn’s disease activity index than the sham group, and significantly greater wellbeing scores. Serum markers of inflammation decreased in the traditional acupuncture group but not in the sham group.

Acupuncture reduces pain & need for sedative drugs during colonoscopy

In order to determine whether acupuncture can reduce the discomfort and anxiety of colonoscopy, 30 patients were randomly assigned to receive acupuncture, sham acupuncture, or no acupuncture. Patients were asked to report on their pain sensations when the endoscope reached four scheduled positions, and their requests for analgesia (midazolam) were recorded. A verbal rating scale was used to assess patient's satisfaction with the level of sedation achieved. Midazolam was required in three patients (30%)in the true acupuncture group, eight (80%) in the sham group, and nine (90%) in the control group. Six patients (60%) in the acupuncture group reported optimum acceptance of colonoscopy compared with only one (10%) in the sham group and none in the control group. The study concludes that acupuncture can decrease the demand for sedative drugs during colonoscopy by reducing discomfort and anxiety of the patient and help avoid the adverse effects of pharmacologic sedation.

ACUPUNCTURE FOR CROHN’S DISEASE

A recent trial of traditional acupuncture for the treatment of Crohn’s disease carried out at the University of Nuremberg has shown it to be statistically more effective than sham acupuncture. 51 patients with Crohn’s disease were randomly assigned to two groups. Both groups received ten treatments over a four week period. The TCM group received needles at Pishu BL-20, Zhongwan REN-12, Zusanli ST-36 or Shangjuxu ST-37 and Tianshu ST-25, three points based on pattern differentiation (Spleen qi deficiency, damp-heat, Kidney deficiency or Liver insulting the Spleen), plus moxibustion where appropriate. Needles were manipulated as long as deqi was present. The control group received shallow sham acupuncture at non-acupuncture points without obtaining deqi. A survey showed that the sham group believed they were receiving real acupuncture to almost the same degree as in the treatment group. Outcome was measured by the Crohn’s Disease Activity Index which rates eight symptoms and signs such as diarrhoea, abdominal pain, well-being and red blood cell count. The real acupuncture group showed a significantly greater benefit which persisted when all patients were reassessed after 16 weeks. At this stage the treatment group showed a significant improvement in al-acid glycoprotein, a marker of bowel inflammation

BOWEL OBSTRUCTION & ACUPUNCTURE

Writing in the journal Medical Acupuncture, Martha Grout MD describes 2 cases of small bowel obstruction treated by acupuncture. Obstruction is the most common surgical condition of the small intestine. Patients are frequently hospitalised for several days and may require surgical intervention for definitive treatment. Mean length of hospitalisation in 1 study was 15.3 days and mortality is reported to range from 5%-75% depending on the cause of the obstruction. In the first case a 27-year-old man who presented to the emergency department of Phoenix (Arizona) Memorial Hospital was treated with standard medical management and acupuncture treatment at Zhongwan REN 12 and Zusanli ST-36 bilaterally. No further needles were used because the treating physician was concerned that stimulating the small intestine directly, e.g. by needling Guanyuan REN-4, might lead to increased bowel motility against a closed obstruction with subsequent perforation. Within 6 hours the patient began to improve and the admitting surgeons expressed surprise that his system began to function so soon. In the second case a 65-year-old woman presented to the emergency department of John C. Lincoln Hospital in Phoenix, Arizona with recurrence of symptoms of obstruction she suffered approximately every 6 weeks. She was treated with the standard nasogastric tube and intravenous therapy and additionally received acupuncture at Zhongwan REN-12, Tianshu ST-25, Guanyuan REN-4, Zusanli ST-36 and Neiguan P-6. Within 3 hours, the patient was released feeling well and returned to work the next day, rather than 3-4 days later as had happened after previous episodes. Ten weeks after treatment, no further hospitalisations had occurred.

ACUPUNCTURE FOR FAECAL INCONTINENCE

Italian researchers have carried out a pilot study to investigate the effect of acupuncture on faecal incontinence. Fifteen female patients, median age 60 years, received one acupuncture treatment per week for a ten-week period. Before treatment and at regular intervals after acupuncture sessions, anal continence was assessed by means of recto-anal manovolumetry. Patients experienced a significant improvement in anal continence, with overall mean continence score changing from 10 before treatment to zero at 10 weeks. Patients with irregular bowel habits and/or loose stools also reported significant improvement. On manovolumetric testing, a mean increase of resting pressure (from 25 to 36 mmHg) and sustained squeeze anal pressure (from 41 to 60 mmHg) was reported. The authors suggest that acupuncture may achieve this effect via neuromodulation of recto-anal function, similar to that achieved by sacral nerve stimulation, which is a conventional medical treatment for faecal incontinence.
