Constipation, dolichocolon and colonic kinks
The Dolichocolon concept was the brainchild of Arbuthnot Lane and is based on the the theory that kinking of colon leads to constipation. While colon is like a country road with its own twists and turns (and of course each "colonic country road" is different), the Lane theory suggests that gravity leads to unnatural "kinking" or twisting initially in the fixed parts of colon on the left side. It gradually progresses upward and proximally causing elongation and further kinking.
In fact, Lane was a proponent of colonic resection or a byepass. While initially colonic resection became very popular, it came into disrepute in the early 20th century and now is performed in rare selected cases only.
Lets face it-the concept of dolichocolon or kinking causing a partial obstruction appears simple, straightforward, appealing and plausible (perhaps too simple and straightforward). Furthermore, theoretically speaking, the kinking along with elongation of colon has potential for increased fecal stasis in colon leading to increased water absorption from the fecal contents resulting in "drier" stool and constipation. However, scientific data to support these theoretical concepts is lacking. At the same time, constipation does not appear to be correlated with colonic length and surgery is not beneficial in cases of colonic "kinks" unless a volvulus is present.
Do you or someone close to you have constipation? What is the cause of constipation in your opinion? Does the Lane's theory of dolichocolon make sense and sound believable to you? Please share your thoughts. And click here to read about toilet posture.


During a recent colonoscopy, I was disagnosed with dolichocolon. No treatment was recommended. I hardly ever have constipation as I eat vegetable and fruit daily. I tend to be gassy. I wonder if the condition contributes to it. My stool can get real dry if I don't drink enough water. But I nomrally drink plenty of fluid.
