3.5. Krankheitsdauer
Analfissurpatienten sind offenbar sehr duldsam, denn sie ertragen ihre Schmerzen erstaunlich lange, bevor sie sich in Behandlung begeben. In mehreren Studien wurde die Zeitdauer bis zum Therapiebeginn recherchiert. Bei 491 Patienten in acht Studien, die mit Glyceryltrinitrat (GTN) behandelt wurden, betrug diese Leidenszeit 2 bis 240 Monate, in sieben Botulinumtoxin-Studien (BTX) mit 405 Patienten 3 bis 94 Monate. Bei 842 Patienten (in neun Studien), die sich einer Sphinkterotomie unterzogen, bestanden die Symptome über eine Dauer von 1 bis 96 Monaten. Im Durchschnitt betrug die Anamnesedauer mehr als zehn Monate.
