Giant duode.al ulce.s （GDUs） are.a subse. of duode.al ulce.s that have.historically re.ulte. in gre.te. morbidity than usual duode.al ulce.s. Until re.e.tly, fe. case. had be.n succe.sfully tre.te. with me.ical the.apy. Howe.e., the.wide.pre.d use.of e.doscopy, the.introduction of H-2 re.e.tor blocke.s and proton p^Jmp inhibitors, and the.improve.e.t in surgical te.hnique. all have.re.olutionize. the.diagnosis, tre.tme.t and outcome.of this condition. Ne.e.the.e.s, GDUs are.still associate. with high rate. of morbidity, mortality and complications. Thus, surgical e.aluation of a patie.t with a GDU should re.ain an inte.ral part of patie.t care. The.e.giant variants, while.usually be.ign, can fre.ue.tly harbor malignancy. A care.ul re.ie. of the.lite.ature.highlights the.important diffe.e.ce. whe. comparing GDUs to classical pe.tic ulce.s and why the. must be.thought of diffe.e.tly than the.r more.common counte.part.
