Gregory Marchand

Gregory Joseph Marchand is an American gynecologic surgeon. He is notable for setting three world records in the field of minimally invasive surgery, including tumor[1][2][3] and uterus[4] removal records recognized by Guinness World Records.[5][6][7][8][9]

Marchand is also known for inventing two surgical techniques, namely a salpingectomy technique,[10][11] as well as a laparoscopic cervical cerclage technique.[12][13] His techniques have been the subject of controversy secondary to the practice of morcellation,[14] which has the potential to spread cancer throughout the abdomen.[15]

During the Hacienda HealthCare sexual abuse case in Phoenix, Arizona, Marchand had conducted an extensive medical investigation of the case. According to Marchand in early 2019, there was "no doubt" that the victim had experienced pain,[16][17] and that the lack of monitoring during the woman's pregnancy and childbirth could have easily resulted in fetal death.[18][19] However, Marchand believed that it was very difficult to determine whether the victim had in fact been pregnant multiple times.[20]
