rome_iv_functional_pancreatic_sod: Rome IV Diagnostic Criteria for Functional Pancreatic Sphincter of Oddi Disorder (SOD)

Description

Evaluates the Rome IV diagnostic criteria for Functional Pancreatic Sphincter of Oddi Disorder. Diagnosis requires recurrent, episodic pain of presumed pancreatic origin, absence of other pathology (structural, metabolic, imaging), and elevated sphincter of Oddi basal pressure documented by manometry. This disorder is characterized by presumed intermittent obstruction to pancreatic fluid outflow.

Usage

rome_iv_functional_pancreatic_sod(biliary_pain,
normal_enzymes, normal_imaging,
manometry_high, not_explained_by_other_condition,
symptom_onset_ge_6_months, symptoms_active_last_3_months)

Value

A list containing:

Diagnosis

"Criteria Met for Functional Pancreatic Sphincter of Oddi Disorder (SOD)" or "Criteria Not Met".

Arguments

biliary_pain

Numeric (0 or 1). Presence of recurrent, episodic pain of presumed pancreatic origin (consistent with recurrent pancreatitis). (1 = Yes).

normal_enzymes

Numeric (0 or 1). Documentation of normal pancreatic enzymes (amylase/lipase) *between* pain episodes. (1 = Yes).

normal_imaging

Numeric (0 or 1). Documentation of no pancreatic structural pathology (e.g., mass, chronic pancreatitis changes) on imaging (e.g., EUS, CT, or MRCP). (1 = Yes).

manometry_high

Numeric (0 or 1). Elevated sphincter of Oddi basal pressure documented by manometry (a pressure >= 40 mmHg is diagnostic). (1 = Yes).

not_explained_by_other_condition

Numeric (0 or 1). Are symptoms NOT fully explained by another medical condition? (1 = Yes).

symptom_onset_ge_6_months

Numeric (0 or 1). Did symptom onset occur at least 6 months prior to diagnosis? (1 = Yes).

symptoms_active_last_3_months

Numeric (0 or 1). Have symptoms been active for the last 3 months? (1 = Yes).
