Procedure for Prolapse & Hemorrhoids samer kareem 2,793 Views • 2 years ago

A surgeon begins the PPH stapled hemorrhoidectomy by inserting a circular anal dilator and obturator into the anal canal and then securing the dilator in place with four sutures. The surgeon then inserts a PPH anoscope into the obturator. Next, he places a circumferential purse-string suture of 2-0 Monocryl on a UR-6 needle 4 cm proximal to the dentate line. The surgeon opens a PPH stapler and places its anvil across the purse string. The stapler is then closed and fired; it is held closed for two minutes to improve hemostasis. Prior to firing the stapler in a female patient, the surgeon places a gloved finger in the vagina to ensure the vaginal mucosa and rectal-vaginal septum are not trapped within the jaws of the closed stapler. The surgeon then opens and removes the stapler.
