About this trial
Constipation and defecation disorders affect about 15% of the European population and of those up to 30% of the patients over 65 years of age. For those affected, this is associated with major restrictions in quality of life and high health care costs .
The underlying causes of constipation and defecation are complex and only partially understood.
Intestinal (full wall) resections taken in clinical practice from these patients when conservative therapy has been exhausted show rarefaction of ganglion cell nests in the myenteric plexus and submucosal plexus as well as changes in cholinergic innervation.
Initial histopathological investigations suggest an inflammatory genesis of this rarefaction of ganglion cell nests, which will be further characterised/investigated in the context of this study on the basis of further histopathological and serological investigations. This may lead to novel therapeutic approaches that can causally treat the symptoms of those affected.

blood sample
Diagnostic testwe want to identify a diagnostic option to identify patients, who have a neuropathological distraction of their ganglia cells in the bowel
Treatment groups
Trial outcomes
Primary outcomes
Neuropathological changes of the intestinal wall in patients with bowel evacuation disorder in correlation to clinical defecation score
Clinical outcome measure by score: Altomare Score (name of initiator) score (minimum 0 to maximum 30 points; higher values mean worse outcome)
Secondary outcomes
Correlation of psychic health and neuropathological changes of the intestinal wall in patients with defecation disorder
Changes in QoL and relief from depressive symptoms after surgery measured by clinical psysic health questionnaire (PHQ 9) ; minimum 0 to maximum 27 points; higher scores mean worse outcome
Correlation of anxiety scoring and neuropathological changes of the intestinal wall in patients with defecation disorder
Changes in anxiety symptoms after surgery measured by clinical general anxiety score (GAD 7); minimum 0 to maximum 21 points; higher scores mean worse outcome
Association of pathological findings for autoimmune activation with duration of symptoms according to medical history
Onset of symptoms in correlation to severity and picture of pathological findings in months
Association of pathological findings for autoimmune reaction with an initiating event according to the medical questionaire
Identification of an initiating event to the occurrence of the symptoms
