Research To The Biofeedback Treatment Of The Different Type Of Functional Constipation

Background: The function constipation is one kind of common gastrointestinal disease, and incidence of crowd reaches 4%, particularly in old age can reach about 20%. With the change of social life style and the diet composition, and more knowing of the functional disease, the incidence gets higher year by year, and the age of patients is getting younger than before. Etiology is complicated, the mechanism is not clear, and the influence factor is multitudinous, so the effect of traditional medicinal curative is not obvious, a long period of using medicines may causes the poisonous side-effect, and the financial burden of patient is heavy. Biofeedback treatment is a safe, effective, cheap and non-pharmaceuticals method, it has developed many years on abroad, and studies to some extent in internal recent years, but the curing effect of the various difference types is short of objective clinical parameters.Objective: Classify the type of functional constipation by colonic transit time test and electromyographic examination, and assess the effect of biofeedback treatment.Method: 24 patients who treatment at our gastrointestinal motility center and fit Rome II standard(20 female,4male) were identified. Inquire history and assess bowel frequency and shape, quadrature the accompanying symptom, classify patients by way of the colonic transit time and electromyograph. All patients accept the biofeedback training inthe clinic, and keep on training at home after the symptom improved. After accomplishing 2~4 sessions, assessing bowel symptoms and checking colonic transit time and electromyography again. Stastic and analyse the parameters before and after therapy.Result: 24 patients average age 37.04 years old, and the average course of disease is 6.8 years, through barium enema and electronic colonoscopy get rid of the intestinal and anal orgnic disease. All patients therapy 5.95 times in clinic, and continues training at home1.Through colonic transit time and electromyograohy check, 14 patients are outlet obstructive constipation, 5 patients are slow transir constipation, others are normal transit constipation.2. After curing, except the clinical symptom of 2 patients is notimproved, the clinical symptom of the other patients all has the differentdegree improved. 91.67% of patients' bowel frequency and shapeimproved, the intrgral of accompany symptoms descend (7.04 + 0.33/1.92+ .045), the efficiency is 91.67%.3.Checking colonic transit time of the outlet obstructive constipations, after therapy, the number of markers blow off increased(6.35 + 5.94/18.85 + 1.29).To the slow transit constipation, the number of markers also increase(0.6 + 6.51/19.0 + 14.75, P>0.05) ,but no stastics meaning.4. Electromyography check show that contradiction motion improved after therapy. Amplitude of belly and anal contractions has different level increase, relax amplitude reduced, it has statistics meaning to OOC(P<0.05),but no meaning to STC(P>0.05).Conclusion:1 .The mainly type of functional constipation is OOC through colonictransit time and electromyography check.2. Biofeedback treatment is effect to every type , though it should useful to outlet obstructive constipation from its principle.3. Biofeedback treatment can rehabitiation the belly muscle and basin muscles, also can promote colon movements. It is safety and no any side-effect, this method can regard as the most important way to cure functional constipation.
