Appendicitis

Low pelvic abscesses. A technique of drainage using a small trocar catheter

A low anterior pelvic abscess can be drained transrectally using a 16 F. trocar catheter or chest tube. The tube is anchored intrarectally for dependent drainage or for irrigation with a normal saline solution or an antibiotic solution. A low posterior pelvic abscess secondary to a low anterior resection can be drained transperineally in the same manner.
