PURPOSE: Anorectal manometry has become a routine investigation for the evaluation of patients with anorectal disorders. However, the interpretation of such studies is confounded by the fact that controversial data are reported with regard to the same events. The aim of this study was to measure the reproducibility of the pressure profiles of anorectal manometry in healthy controls for standardization of their measurements. METHODS: Manometric study was performed on different days with 7 days interval in 22 male healthy subjects with the use of a pneumohydraulic capillary perfusion system. RESULTS: For resting pressures with rapid pull-through (RPT) technique, maximum pressure revealed 43.58, 19.8% and mean pressure, 16.02, 14.6% in the order of reproducibility coefficient and coefficient of variation. For resting pressures with stationary pull-through (SPT) technique, maximum pressure; 17.22, 12.2% and mean pressure; 14.66, 26.4%, respectively. For squeezing pressures with RPT technique, maximum pressure; 53.37, 14.3% and mean pressure; 66.32, 23.6%. For squeezing pressures with SPT technique, maximum pressure; 72.80, 11.9%, mean pressure; 93.10, 30.5% and coughing pressure; 69.42, 15.8%, respectively, For anal canal length (ACL) with RPT technique, at resting state; 7.10, 7.9% and at squeezing state; 14.55, 13.7%, respectively. For high pressure zone (HPZ) with RPT technique, at resting state; 6.68, 16.3% and at squeezing state; 11.06, 23.5%. For HPZ with SPT technique, at resting state; 11.28, 25.4% and at squeezing state; 10.04, 17.5%, respectively. For radial asymmetry (RA) with RPT technique, at resting state; 13.76, 42.3% and at squeezing state; 7.86, 22.9%. For RA with SPT technique, at resting state; 24.6, 58.6% and at squeezing state; 14.28, 46.7%, respectively. CONCLUSION: Measurements of resting and squeezing pressure are more reproducible by SPT technique, in which technique it seems that maximum value is more preferred as a representative value. ACL and HPZ are may well measured on resting pressure with SPT technique. Radial asymmetry shows the best reproducibility on squeezing pressure with RPT.

PURPOSE: Measurement of colon transit time is well-known physiologic study for patients with chronic constipation. But information we get from it is frequently inconsistent with patient's complaint. This study was designed to ascertain the actual significance of that measurement. METHODS: The subjects included two groups of patients with chronic constipation. One group consists of 32 patients(group A), The other group 36 patients(group B). Colon transit time study and defecographic examinations were done using previously described methods. But the former study was a little modified in group A, in which sodium phosphate enema was given at the previous day of oral intake of radio-opaque markers. Findings of colon transit time study and their relations to the defecographic results were compared with each other. RESULTS: As for the 5th day-findings of colon transit time, 6 cases(18.7%) were abnormal in group A and 3 cases(8.4%) in group B(statistically not different). As for the 3rd day-findings, 15 cases(46.9%) were abnormal in group A and 7 cases(19.5%) in group B( statistically different, p=0.0163). Defecographic findings showed 7 cases(21.9%) of outlet obstruction pattern in group A and 9 cases(25%) in group B. Correlations between these findings and those of colonic transit time studies were not proven statistically. CONCLUSION: Colon transit time study with single marker bolus and the 5th day photography technique was considered not to reflect the actual conditions of patients with chronic constipation. But sodium phophate enema, given to patients before starting the study, seemed to enhance the accuracy of study.
