PERFORATION OF the appendix into neighboring viscera is an uncommon sequel to acute appendicitis and persistence of the fistula between the appendix and a viscus is even more rare. Jaffe and Evans reviewed 44 cases of appendiceal-vesical fistula1 but few of these were considered to be related to previous appendicitis. Two cases of appendicealileal fistula were reported by Shallow et al2 and both of them were clearly related to antecedent appendicitis.
We have been able to find only one report3 of a persistent appendiceal-sigmoid fistula and because of the rarity of the lesion and the diagnostic confusion associated with it we wish to report another such case to draw further attention to it.
