Maternal diaphragmatic hernia is a rare disorder of pregnancy. Laparoscopic repair of diaphragmatic hernias is gaining more and more consideration among the surgical community. To date, only a few centers have reported using the laparoscopic approach for diaphragmatic hernias occurring in pregnancy. As congenital diaphragmatic hernias occur mostly on the left side, a right lateral position would theoretically facilitate the surgery and would render an eventual simultaneous left thoracoscopy feasible without repositioning the patient. However, such a position in a pregnant woman has serious implications because of possible inferior vena cava compression by the gravid uterus. We performed a laparoscopic reduction and repair of a left foramen of Bochdalek hernia in a 26-week-pregnant patient, using a right lateral position. The right lateral position facilitated the procedure, without any adverse outcome for the fetus or the mother. This approach should be considered for any left diaphragmatic hernia repair occurring in pregnancy.
