Abstract

OBJECTIVE: The aim of this study was to investigate and present the clinical characteristics of diaphragm endometriosis, to approach the pathogenetic mechanisms, and to answer the question of whether this disease can be considered an extended form of pelvic endometriosis. STUDY DESIGN: It was a retrospective comparative one-to-one analysis of 202 cases. Two groups of patients were compared: Group 1 patients with diaphragm endometriosis vs Group 2 (control group) with pelvis endometriosis, each with 101 patients. RESULTS: Patients with diaphragm endometriosis had extreme significantly higher prevalence of severe pelvis endometriosis included deep infiltrated endometriosis and severe adhesions in term of complete Douglas obliteration (p value = 0.0001). There was neither age nor BMI difference in two groups. Besides of cyclic shoulder or upper abdomen pain there was no difference of symptoms. CONCLUSION: Diaphragm endometriosis is a rare condition with an approximate prevalence of 1.1% of all endometriosis cases. Since the symptoms are very specific and patients do not associate the pain with diaphragmatic endometriosis, the symptoms should be asked about explicitly. If patients with diaphragmatic endometriosis have no symptoms, the lesions do not necessarily need to be removed. The pathogenesis is still unclear. The authors of this study consider this disease to be an extended form of severe pelvic and deep infiltrated endometriosis. However, the right-side dominance still cannot be explained. Further research is needed to fully understand the origin of diaphragmatic endometriosis.
