Systemic sclerosis patients rarely experience fecal incontinence or abnormal anorectal function. Anorectal manometry is not effective in diagnosing gastrointestinal issues in systemic sclerosis.

Area of Science:

Gastroenterology
Rheumatology
Clinical Physiology

Background:

Systemic sclerosis (SSc) is a multisystem autoimmune disease.
Gastrointestinal (GI) dysmotility is a common complication of SSc.
Esophageal involvement is frequently observed in SSc patients.

Purpose of the Study:

To compare esophageal and anorectal function in SSc patients.
To evaluate the utility of anorectal manometry in diagnosing GI involvement in SSc.

Main Methods:

Esophageal and anorectal manometry were performed on 26 SSc patients.
Anorectal function parameters were compared between patients with normal and abnormal esophageal function.

Main Results:

Related Experiment Videos

65% of patients exhibited severe esophageal dysfunction.

Only 11.5% reported fecal incontinence.

Anorectal function parameters did not differ significantly between groups with normal and disturbed esophageal function.

Conclusions:

Abnormal anorectal function and fecal incontinence are uncommon in unselected SSc patients.
Anorectal manometry is not a reliable tool for differentiating GI involvement in SSc.
