| Abstract |
We challenged the two hypotheses: first, that defecation can be suppressed for an extended time, and second, if so, that this has an effect on upper colonic motility. Thus we studied 12 male volunteers with conditions of identical nutrition and patterns of physical activity over a two-week period, where one week with normal defecation and one week with voluntary prolonged suppression of defecation followed each other in randomized order. Frequencies of defecation, stool weights, total and segmental colonic transit times (using radiopaque markers) were compared. Frequency of defecations and stool weights were lower during suppressed defecation [8.9 +/- 0.66 vs 3.7 +/- 0.41 (mean +/- SE) bowel movements per week, P = 0.003, and 1.30 +/- 0.09 vs 0.98 +/- 0.13 kg/week, P = 0.01]. Total transit times were increased from 28.8 +/- 4.4 to 53.1 +/- 4.3 hr, P = 0.004. Segmental transit times were increased in the rectosigmoid (from 8.83 +/- 3.6 to 32.1 +/- 5.6 hr, P = 0.04) and right hemicolon (from 14.5 +/- 0.9 hr to 19.7 +/- 1.5 hr, P = 0.02) by suppression of defecation. We conclude that defecation habits may induce changes in colonic function such as those seen in constipation and that functional anorectal outlet obstruction may, probably by reflex mediation, affect the right colon. |

Attention Score in Context
This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 August 2017.
All research outputs
#3,405,021
of 25,381,151 outputs
Outputs from Digestive Diseases and Sciences
#423
of 4,662 outputs
Outputs of similar age
#796
of 15,060 outputs
Outputs of similar age from Digestive Diseases and Sciences
#2
of 7 outputs
Altmetric has tracked 25,381,151 research outputs across all sources so far. Compared to these this one has done well and is in the 86th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,662 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one has done particularly well, scoring higher than 90% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 15,060 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 94% of its contemporaries.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than 5 of them.
