Saint's triad

Saint's triad is a unique medical condition that defines the simultaneous presence of three specific conditions:

• Cholelithiasis: Formation of gallstones.
• Hiatal hernia: Protrusion of the upper part of the stomach into the thorax through a tear or weakness in the diaphragm.
• Diverticular disease: Presence of diverticula in the digestive tract, primarily in the colon.

Historical Background

Named in honor of the distinguished British surgeon, Prof C.F.M. Saint, the triad recognizes his significant contributions to medical academia, especially in establishing the premier school of surgery in South Africa. Saint's philosophy in patient care diverged from traditional diagnostic tenets. He championed the notion that clinicians must remain open to the possibility that a patient's presentation could be a manifestation of multiple concurrent disorders. This approach was especially relevant when the patient's history and physical examination findings did not conform neatly to the typical presentation of a single condition.

Saint's Triad hence serves as a compelling deviation from the principle of Occam's Razor, which emphasizes that diagnostic conclusions should involve the fewest possible assumptions. Instead, it parallels the sentiment of Hickam's dictum, which posits that a patient can have as many diseases as they darn well please.

Recent Developments

While historically the coexistence of these three conditions in Saint's Triad was deemed coincidental without any underlying pathophysiological foundation, contemporary research suggests a possible interconnected basis.

• Obesity as a Common Denominator: Modern clinical observations have identified obesity as a predisposing factor for all three conditions present in Saint's triad. The metabolic and mechanical changes associated with obesity can induce gallstone formation, predispose to hiatal hernias, and foster the development of diverticular disease.
• Connective Tissue Defect - "Herniosis": There's emerging evidence to suggest that an underlying connective tissue anomaly might predispose individuals to hernias, including hiatal hernias, and other manifestations included in Saint's triad. This proposed condition, tentatively termed "herniosis," would represent a shared pathophysiological pathway linking these conditions.

Conclusion

Saint's Triad, while historically seen as a cautionary example against oversimplification in diagnosis, has evolved to potentially represent a unique intersection of metabolic, mechanical, and connective tissue disorders. As our understanding of disease etiology and pathophysiology expands, conditions like Saint's Triad remind clinicians of the complexities of human health and disease.
