Somatization disorder in sphincter of Oddi dysfunction

Area of Science:

• Gastroenterology
• Psychiatry
• Women's Health

Background:

• Sphincter of Oddi dysfunction (SOD) is a biliary disorder with established pathophysiology and surgical treatments.
• Understanding the psychological factors associated with SOD is crucial for comprehensive patient care.

Purpose of the Study:

• To investigate the prevalence of somatization, history of sexual and physical abuse, socially compliant attitudes, and familial psychiatric illness in women with SOD.
• To determine if women with SOD are overrepresented in these psychological and social measures compared to controls.

Main Methods:

• A case-controlled, cross-sectional study matched 33 women with SOD to 33 controls by age, sex, and race.
• Questionnaires assessed somatization, abuse history, social desirability, and family psychiatric history.
• Statistical analyses included chi-squared tests, t-tests, and Pearson correlation coefficients, with Bonferroni corrections.

Main Results:

• Women with SOD exhibited significantly higher rates of nongastroenterological somatic complaints compared to controls (p < .0001).
• SOD patients reported a statistically significant increase in childhood sexual abuse (p < .02), but not physical abuse, compared to controls.
• The severity of childhood sexual abuse strongly correlated with the severity of adult somatization.

Conclusions:

• Sphincter of Oddi dysfunction in women is associated with high levels of somatization and a significantly higher incidence of childhood sexual abuse.
• The severity of childhood sexual abuse is linked to the severity of somatization in adulthood, suggesting a potential psychological model for SOD.
• These findings indicate a need for increased psychiatric consideration in the management of women diagnosed with SOD.
