The method of tumor excision in the Trauma Center series is called the "Powell Procedure." It must be carried out as follows: * Find the tumor using the Ultrasound (note: leaving a tumor unattended after disclosing it will cause it to fade from view) * Incise the middle of the tumor vertically with the scalpel * Drain the cytoplasm (note: leaving too long a gap between draining and excising allows more cytoplasm to ooze out, breaking the chain and leaving you to repeat the drainage) * Excise the tumor around the edges * Place the tumor on the tray using the forceps * Cover the wound with a synthetic membrane * Apply antibiotic gel to the membrane to set it * (Under the Knife only) massage the membrane with your hand * Treat any polyps formed in the process
