[Verse 1] Left vagal trunk rolls anterior, hepatic branches peel away Feeding bile decisions, liver traffic every day Then the nerve of Latarjet runs the lesser curve down south Crow's foot fanning at the antrum, five toes spread toward the mouth Acid cells above that crow's foot, antral motor fibers low Cut above to spare the pylorus — that's the selective window [Chorus] Vagus, vagus, two trunks at the hiatus Anterior left, posterior right, don't you confuse 'em at the table Criminal nerve of Grassi hides up high behind the crus Miss that fiber, ulcer's back — recurrence coming back to you Crow's foot, celiac, Latarjet — draw the map before you sever Confirm your cut, sweep the hiatus, parietal cell vagotomy forever [Verse 2] Now the right trunk drops posterior, celiac branch first to split Feeds the solar plexus ganglia, sympathetics benefit Then posterior Latarjet mirrors left along the curve But buried high and posterior, Grassi's the criminal nerve Arises before the trunk descends — most surgeons miss the spot Sweep behind the esophagus or leave that fiber hot [Chorus] Vagus, vagus, two trunks at the hiatus Anterior left, posterior right, don't you confuse 'em at the table Criminal nerve of Grassi hides up high behind the crus Miss that fiber, ulcer's back — recurrence coming back to you Crow's foot, celiac, Latarjet — draw the map before you sever Confirm your cut, sweep the hiatus, parietal cell vagotomy forever [Verse 3] Truncal vagotomy — blunt axe, kills the whole supply Antrum loses motor rhythm, pylorus won't comply So you drain it — pyloroplasty opens what the nerve controlled Without that drainage, gastric stasis, food pools, patient cold Selective spares the hepatic branch, celiac off the hook Highly selective — just the parietal cells, go page the textbook [Bridge] Greater splanchnics wire into the celiac plexus deep Visceral afferents haul the pain through fibers half asleep Epigastric burning — that's your referred ulcer ache Left shoulder speaks in phrenic tongue when diaphragm's awake Down in Auerbach's and Meissner's plexus, enteric neurons hum Cajal's interstitial cells set pace — when they're gone, stomach's numb GIST grows from those same Cajal cells — the pacemaker turned malign Gastroparesis walks the same anatomy, different design [Chorus] Vagus, vagus, two trunks at the hiatus Anterior left, posterior right, don't you confuse 'em at the table Criminal nerve of Grassi hides up high behind the crus Miss that fiber, ulcer's back — recurrence coming back to you Crow's foot, celiac, Latarjet — draw the map before you sever Confirm your cut, sweep the hiatus, parietal cell vagotomy forever
