[Verse 1]
Surgeons mapping the gut like cartographers of pressure,
Anorectal manometry — we measure every tether,
Resting tone from the internal sphincter, smooth muscle in command,
Squeeze pressure from external fibres, voluntary contraband,
High-resolution probes recording microbars along the canal,
Rectoanal inhibitory reflex — RAIR — your diagnostic pal,
Loss of RAIR points straight to Hirschsprung's, absent ganglion cells,
While hypertonic internal sphincter rings the fissure-in-ano bells
[Chorus]
Testar, medir, mapear — test the gut, diagnose the state,
Gastric emptying, manometria — we can't afford to wait,
Trânsito cólico, pH — every signal has its weight,
Physiologic testing, conhecimento, graduate
[Verse 2]
Pudendal nerve terminal motor latency — listen to the wire,
Electrode glove on the examiner's finger, signal travels higher,
Prolonged latency means neuropathy, the pelvic floor's degraded,
Post-obstetric trauma, chronic straining, sphincter architecture faded,
Balloon expulsion test — simple geometry of function,
Fifty mils of water, two minutes, basic pelvic junction,
Retained balloon means dyssynergia — outlet obstruction caught,
Biofeedback is the treatment pathway that the physio wrought
[Chorus]
Testar, medir, mapear — test the gut, diagnose the state,
Gastric emptying, manometria — we can't afford to wait,
Trânsito cólico, pH — every signal has its weight,
Physiologic testing, conhecimento, graduate
[Verse 3]
Gastric emptying scintigraphy — radiolabelled scrambled egg,
Technetium ninety-nine on solid meal, now watch the stomach beg,
Half-emptying time beyond ninety minutes at the four-hour scan,
Gastroparesis confirmed — vagal damage or diabetic plan,
Before your fundoplication check the stomach clears the plate,
Dysmotility pre-op changes surgical technique and fate,
pH impedance tracks acid and non-acid bolus too,
DeMeester score above fourteen-point-seven, GORD breaks through
[Bridge]
Esophageal manometry before any foregut cut,
High-resolution topography reveals the pressure glut,
Chicago Classification — hypotensive LOS,
Achalasia versus spasm — get the diagnosis across,
Scintigraphy para o cólon — radiopaque markers ingested,
Five or more retained at day five, slow transit suspected,
Segmental delay — sigmoid versus pan-colonic spread,
Shapes the operation — subtotal colectomy ahead
[Chorus]
Testar, medir, mapear — test the gut, diagnose the state,
Gastric emptying, manometria — we can't afford to wait,
Trânsito cólico, pH — every signal has its weight,
Physiologic testing, conhecimento, graduate
[Outro]
So run the tests before the knife, let physiology confess,
Manometry, scintigraphy, markers in the press,
O diagnóstico é preciso — precision guides the hand,
Physiologic testing builds the surgical command
