rome_iv_functional_defecation_disorders: Rome IV Diagnostic Criteria for Functional Defecation Disorders

Description

Evaluates the Rome IV criteria for diagnosing Functional Defecation Disorders (FDD). These disorders are characterized by a set of defecatory symptoms (straining, incomplete evacuation, etc.) along with objective evidence of impaired defecatory dynamics on anorectal function testing (e.g., manometry or balloon expulsion). The diagnosis requires at least two out of four core symptoms, objective testing evidence, and exclusion of organic causes.

Usage

                                        sensation_anorectal_blockage_ge_25_percent,
                                        manual_maneuver_ge_25_percent,
                                        inadequate_defecatory_propulsion,
                                        dyssynergic_defecation, other_conditions_excluded)

Value

A list containing:

Diagnosis

The resulting FDD subtype (Inadequate Defecatory Propulsion, Dyssynergic Defecation, or General FDD).

Arguments

straining_ge_25_percent

Numeric (0 or 1). Straining during at least 25% of defecations. (1 = Yes).

sensation_incomplete_evacuation_ge_25_percent

Numeric (0 or 1). Sensation of incomplete evacuation in at least 25% of defecations. (1 = Yes).

sensation_anorectal_blockage_ge_25_percent

Numeric (0 or 1). Sensation of anorectal obstruction/blockage in at least 25% of defecations. (1 = Yes).

manual_maneuver_ge_25_percent

Numeric (0 or 1). Use of manual maneuvers to facilitate at least 25% of defecations. (1 = Yes).

inadequate_defecatory_propulsion

Numeric (0 or 1). Objective evidence of impaired propulsion (e.g., ineffective pushing phase on manometry). (1 = Yes).

dyssynergic_defecation

Numeric (0 or 1). Objective evidence of dyssynergia (e.g., paradoxical puborectalis contraction or inadequate relaxation). (1 = Yes).

other_conditions_excluded

Numeric (0 or 1). Organic causes for the symptoms excluded (e.g., neoplasm, IBS). (1 = Yes).
