We report a case of hydrothorax as a complication of laparoscopic myomectom
y in an otherwise healthy woman. The most likely cause of the patient's hyd
rothorax was irrigation fluid moving from the peritoneal cavity into the pl
eural space via defects in the diaphragm. Anaesthestists and surgeons shoul
d consider hydrothorax as a potential complication in any patient undergoin
g laparoscopy.
