Objective: To review the clinical presentations of and management opti
ons for diaphragmatic endometriosis. Design: Retrospective review. Set
ting: Referral center. Patient(s): Twenty-four women with endometriosi
s of the diaphragm. Intervention(s): Surgical management. Main Outcome
Measure(s): Diagnostic accuracy and therapeutic feasibility of operat
ive laparoscopy. Result(s): Operative findings in 17 patients included
2-5 spots of endometriosis on the diaphragm measuring <1 cm. Seven wo
men had numerous lesions scattered across the diaphragm. Lesions were
bilateral in 8 patients, limited to the right hemidiaphragm in 14 pati
ents, and limited to the left hemidiaphragm in 2 patients. In 7 patien
ts, six endometriosis lesions were directly in the line of the left ve
ntricle and three lesions were adjacent to the phrenic nerve. Endometr
iosis was infiltrating into the muscular layer of the diaphragm in 7 p
atients. The symptoms in all 7 symptomatic patients decreased signific
antly after treatment, with a minimum follow-up period of 12 months. N
o postoperative complications occurred. Conclusion(s): The abdominal d
iaphragm can be involved with endometriosis and can be diagnosed and t
reated effectively with the use of videolaparoscopy. (C) 1998 by Ameri
