Electromyographic Biofeedback Therapy in Patients With Dyssynergic Defecation

This study aimed to investigate the effects of game-based electromyographic (EMG) biofeedback therapy on the quality of life and sleep quality of individuals diagnosed with dyssynergic defecation.

Neuropathological Changes of the Intestinal Wall in Patients With Bowel Evacuation Disorders

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.

"The Effect of Abdominal Massage on Gastrointestinal Functions in Mechanically Ventilated Patients Receiving Enteral Nutrition in Intensive Care"

This study aims to evaluate the effects of abdominal massage on gastrointestinal functions in mechanically ventilated patients receiving enteral nutrition in intensive care units.

The ReVo Study: Low-volume vs High-volume Rectal Irrigation

Rectal irrigation, which is the introduction of warm tap water through the anal canal into the rectum to initiate defaecation, is recommended to be considered in patients with chronic constipation, which is refractory to conservative measures such as lifestyle modification, laxatives, nurse-led bowel retraining programmes which focuses on bio-feedback as well as psychosocial support. Two systems of rectal irrigation are available based on volume delivered, low and high volume. It is unknown if one type of irrigation is superior to the other and whether one type has better outcomes in patients with a particular pathology. Therefore, a comparison is required between the two types of irrigation to assess their acceptability as a therapy and response rates in patients with chronic constipation secondary to difficulty emptying rectum. This trial/research aims to compare low-volume rectal irrigation with high-volume rectal irrigation in patients with chronic constipation secondary to disorders of difficulty emptying rectum. The main questions it aims to answer are: * if one type of rectal irrigation is superior to the other * whether one type of rectal irrigation has better outcomes in patients with a particular pathology on pelvic floor ultrasound * assess the acceptability and response rates to rectal irrigation. Participants upon recruitment will be allocated to either low-volume rectal irrigation or high volume rectal irrigation groups. This will purely be by chance where the possibility of being in either of the groups will be 50%. They will then undergo a baseline assessment with four quality-of-life questionnaires and clinical examination. Following this a pelvic floor ultrasound will be performed to assess the cause of their symptoms. Lastly they will be provided training on using rectal irrigation (the type they have been assigned to). They will then be asked to commence irrigation at home from the next day. Participants will continue to use irrigation for three months and then have a three-monthly follow-up where the quality of life questionnaires will be filled again. This data will then be used to assess any improvement in symptoms after using rectal irrigation. After three months of using rectal irrigation, participation in the trial will come to and end.
