Rectal tenesmus

Inability to adequately empty the bowel

Field	Value
name	Rectal tenesmus
field	Gastroenterology, general surgery

Rectal tenesmus is a feeling of incomplete defecation. It is the sensation of inability or difficulty to empty the bowel at defecation, even if the bowel contents have already been evacuated. Tenesmus indicates the feeling of a residue, and is not always correlated with the actual presence of residual fecal matter in the rectum. It is frequently painful and may be accompanied by involuntary straining and other gastrointestinal symptoms. Tenesmus has both a nociceptive and a neuropathic component.

Often, rectal tenesmus is simply called tenesmus. The term rectal tenesmus is a retronym to distinguish defecation-related tenesmus from vesical tenesmus. Vesical tenesmus is a similar condition, experienced as a feeling of incomplete voiding despite the bladder being empty.

Tenesmus is a closely related topic to obstructed defecation. The term is , , .

Considerations

Tenesmus is characterized by a sensation of needing to pass stool, accompanied by pain, cramping, and straining. Despite straining, little stool is passed. Tenesmus is generally associated with inflammatory diseases of the bowel, which may be caused by either infectious or noninfectious conditions. Conditions associated with tenesmus include:

Amoebiasis
Chronic arsenic poisoning
Coeliac disease
Colorectal cancer
Anal melanoma
Cystocele
Cytomegalovirus (in immunocompromised patients)
Diverticular disease
Dysentery
Hemorrhoid, which are prolapsed
Imperforate hymen
Inflammatory bowel disease
Irritable bowel syndrome
Ischemic colitis
Kidney stones, when a stone is lodged in the lower ureter
Pelvic organ prolapse
Radiation proctitis
Rectal gonorrhea
Rectal lymphogranuloma venereum
Rectal parasitic infection, particularly Trichuris trichiura (whipworm)
Rectocele
Shigellosis
Ulcerative colitis

Tenesmus (rectal) is also associated with the installation of either a reversible or non reversible stoma where rectal disease may or may not be present. Patients who experience tenesmus as a result of stoma installation can experience the symptoms of tenesmus for the duration of the stoma presence. Long term pain management may need to be considered as a result.

Treatment

Pain relief is administered concomitantly to the treatment of the primary disease causing tenesmus.
