Endometriosis associated with appendiceal intussusception. A report of two cases.

While endometriosis is a commonly encountered surgical problem, involvement of the gastrointestinal tract is infrequent and appendiceal involvement rate. Intussusception of the appendix is more frequent. Accordingly, the concurrence of appendiceal endometriosis and intussusception is remarkable. We treated two such patients. The clinical presentation of these patients is varied, with most having abdominal pain, nausea and diarrhea. Asymptomatic cases may be found at surgery for unrelated problems. Correct diagnosis preoperatively is uncommon and most likely when the patients also have a palpable mass.
