Eighteen patients with chronic constipation were diagnosed as having paradoxical puborectalis contraction (PPC) as the cause for their constipation. The diagnosis of PPC was made after office evaluation, colonic transit study, manometry, cinedefecography, and electromyography (EMG). These 18 patients had a mean duration of symptoms of 26.9 years; none of these patients had unassisted bowel movements. Fourteen patients had a mean of 4.6 laxative-induced bowel evacuations per week, and 11 patients had a mean of 4.4 enema-induced bowel evacuations per week. Patients underwent a mean of 8.9 one-hour EMG-based biofeedback sessions. At a mean follow-up of 9.1 (range, 0.5-12) months, these 18 patients had a mean of 7.3 unassisted bowel actions per week (P less than 0.0001). In addition, persistent laxative use was reported by only two patients, and, in both cases, this was once a week or less (P less than 0.001). Similarly, enema use was reported by only three patients, one once weekly and the other two thrice weekly (P less than 0.002). No biofeedback-related complications were identified. EMG-based biofeedback is a valuable technique associated with an 89 percent success rate in the treatment of PPC.

SETTING: Constipation is mentioned occasionally as a possible tobacco withdrawal symptom, but no systematic data have been published on this issue. DESIGN: Smokers' clinic patients provided ratings of their level of constipation on three occasions prior to their quit date, and then weekly after they stopped smoking. The total of 1067 participants maintained at least 1 week of continuous abstinence and provided usable data. FINDINGS: The three precessation ratings of constipation were stable. After cessation of smoking, the ratings increased significantly (P < 0.01). In 514 patients who maintained continuous abstinence for 4 weeks and provided complete data, constipation peaked at 2 weeks but remained elevated over the whole period. The net proportion of patients affected was 17%, including 9% who were symptom-free at baseline and became very or extremely constipated. In patients on nicotine replacement the increase in constipation, although significant, was less than in patients on bupropion. CONCLUSIONS: Clinicians treating smokers need to be aware of a possibility that one in six quitters develop constipation, and that for about one in 11 the problem can be severe. Descriptions of tobacco withdrawal syndrome should include constipation.

BACKGROUND: Measuring colonic transit time (CTT) by the radio-opaque marker method is simple, widely available and important for the diagnosis of slow transit constipation. Moreover, the effects of gender and menstrual cycle on CTT remain controversial. Thus, in this study, we examined the effects of gender and menstrual cycle on CTT in healthy subjects. METHODS: We measured CTT in 42 healthy subjects (21M, 21F) by using a radio-opaque marker, Kolomark. Two simple abdominal radiographs were taken on the 4th and 7th days. Average daily intake of dietary fiber and menstrual history were surveyed. RESULTS: The mean CTT of the 42 healthy subjects was 26.5 +/- 19.4 hours. The mean CTT was not significantly different between the male and female subjects (22.3 +/- 16.1 h vs. 30.1 +/- 21.4 h, p > 0.05). However, the mean CTT of 11 female subjects in the luteal phase was significantly longer than that of 10 female subjects in the follicular phase (40.9 +/- 19.0 h vs. 20.6 +/- 19.2 h, p < 0.05). Serum progesterone level, age, BMI, and the average daily intake of dietary fiber did not correlate with CTT. CONCLUSION: The effects of the menstrual cycle should be considered in interpreting CTT in young women.
