Gregory J. Marchand (born 1978 [1] ) is an American surgeon. He is noted for his research and publications on laparoscopic hysterectomy, [2] salpingectomy, [3] [4] [5] and neonatology. [6]
Marchand is known for developing two surgical techniques, a salpingectomy technique [7] [8] and a laparoscopic cervical cerclage technique. [9] [10]
Marchand has published on the effects of COVID-19 vaccination on pregnancy, [11] [12] [13] and other topics on neonatal medicine. [6] [14]
Marchand has expressed concerns over the effects of the respiratory syncytial virus vaccine on pregnancy, saying that it could raise the risk of preterm births. [15] [16] Additionally, he has voiced concerns over restrictive legislation on abortions in Arizona, [17] as well as the shortage of Ob-Gyn physicians in the United States. [18]
Marchand's notable cases include a heterotopic pregnancy, among others. [19] Marchand also currently holds a few different tumor and uterus removal records. [20]
Marchand's techniques have been the subject of controversy secondary to the practice of morcellation, [21] [22] which has the potential to spread cancer throughout the abdomen. [23]
Marchand has published textbooks on laparoscopic surgery.
Marchand has published several dozen articles in scientific journals. [26]
Laparoscopy is an operation performed in the abdomen or pelvis using small incisions with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.
Tubal ligation is a surgical procedure for female sterilization in which the fallopian tubes are permanently blocked, clipped or removed. This prevents the fertilization of eggs by sperm and thus the implantation of a fertilized egg. Tubal ligation is considered a permanent method of sterilization and birth control.
Hysterectomy is the surgical removal of the uterus and cervix. Supracervical hysterectomy refers to removal of the uterus while the cervix is spared. These procedures may also involve removal of the ovaries (oophorectomy), fallopian tubes (salpingectomy), and other surrounding structures. The term “partial” or “total” hysterectomy are lay-terms that incorrectly describe the addition or omission of oophorectomy at the time of hysterectomy. These procedures are usually performed by a gynecologist. Removal of the uterus renders the patient unable to bear children and has surgical risks as well as long-term effects, so the surgery is normally recommended only when other treatment options are not available or have failed. It is the second most commonly performed gynecological surgical procedure, after cesarean section, in the United States. Nearly 68 percent were performed for conditions such as endometriosis, irregular bleeding, and uterine fibroids. It is expected that the frequency of hysterectomies for non-malignant indications will continue to fall given the development of alternative treatment options.
HELLP syndrome is a complication of pregnancy; the acronym stands for hemolysis, elevated liver enzymes, and low platelet count. It usually begins during the last three months of pregnancy or shortly after childbirth. Symptoms may include feeling tired, retaining fluid, headache, nausea, upper right abdominal pain, blurry vision, nosebleeds, and seizures. Complications may include disseminated intravascular coagulation, placental abruption, and kidney failure.
Tocolytics are medications used to suppress premature labor. Preterm birth accounts for 70% of neonatal deaths. Therefore, tocolytic therapy is provided when delivery would result in premature birth, postponing delivery long enough for the administration of glucocorticoids, which accelerate fetal lung maturity but may require one to two days to take effect.
Adenomyosis is a medical condition characterized by the growth of cells that proliferate on the inside of the uterus (endometrium) atypically located among the cells of the uterine wall (myometrium), as a result, thickening of the uterus occurs. As well as being misplaced in patients with this condition, endometrial tissue is completely functional. The tissue thickens, sheds and bleeds during every menstrual cycle.
Salpingectomy refers to the surgical removal of a fallopian tube. This may be done to treat an ectopic pregnancy or cancer, to prevent cancer, or as a form of contraception.
Placenta accreta occurs when all or part of the placenta attaches abnormally to the myometrium. Three grades of abnormal placental attachment are defined according to the depth of attachment and invasion into the muscular layers of the uterus:
A hydrosalpinx is a condition that occurs when a fallopian tube is blocked and fills with serous or clear fluid near the ovary. The blocked tube may become substantially distended giving the tube a characteristic sausage-like or retort-like shape. The condition is often bilateral and the affected tubes may reach several centimeters in diameter. The blocked tubes cause infertility. A fallopian tube filled with blood is a hematosalpinx, and with pus a pyosalpinx.
Tokophobia is a significant fear of childbirth. It is a common reason why some women request an elective cesarean section. The fear often includes fear of injury to the baby, genital tract, or death. Treatment may occur via counselling.
Immunization during pregnancy is the administration of a vaccine to a pregnant individual. This may be done either to protect the individual from disease or to induce an antibody response, such that the antibodies cross the placenta and provide passive immunity to the infant after birth. In many countries, including the US, Canada, UK, Australia and New Zealand, vaccination against influenza, COVID-19 and whooping cough is routinely offered during pregnancy.
Fallopian tube obstruction, also known as fallopian tube occlusion is a major cause of female infertility. Blocked fallopian tubes are unable to let the ovum and the sperm converge, thus making fertilization impossible.
An interstitial pregnancy is a uterine but ectopic pregnancy; the pregnancy is located outside the uterine cavity in that part of the fallopian tube that penetrates the muscular layer of the uterus. The term cornual pregnancy is sometimes used as a synonym, but remains ambiguous as it is also applied to indicate the presence of a pregnancy located within the cavity in one of the two upper "horns" of a bicornuate uterus. Interstitial pregnancies have a higher mortality than ectopics in general.
A cervical pregnancy is an ectopic pregnancy that has implanted in the uterine endocervix. Such a pregnancy typically aborts within the first trimester, however, if it is implanted closer to the uterine cavity – a so-called cervico-isthmic pregnancy – it may continue longer. Placental removal in a cervical pregnancy may result in major hemorrhage.
Michael L. Brodman is an American gynecologist and obstetrician and currently the Ellen and Howard C. Katz Professor and Chairman of the Department of Obstetrics, Gynecology and Reproductive Science at Mount Sinai Hospital, Mount Sinai Health System, and Icahn School of Medicine at Mount Sinai in New York City. He is recognized internationally as a pioneer in the field of urogynecology.
Scott B. Ransom has worked across the healthcare ecosystem over 30 years as a physician, researcher, teacher, author, executive, strategy consultant and investor.
A lymphocele is a collection of lymphatic fluid within the body not bordered by epithelial lining. It is usually a surgical complication seen after extensive pelvic surgery and is most commonly found in the retroperitoneal space. Spontaneous development is rare.
Vaginal evisceration is an evisceration of the small intestine that occurs through the vagina, typically subsequent to vaginal hysterectomy, and following sexual intercourse after the surgery. It is a surgical emergency.
Kurt Karl Stephan Semm was a German gynecologist and pioneer in minimally invasive surgery. He has been called "the father of modern laparoscopy".
Prophylactic salpingectomy is a preventative surgical technique performed on patients who are at higher risk of having ovarian cancer, such as individuals who may have pathogenic variants of the BRCA1 or BRCA2 gene. Originally salpingectomy was used in cases of ectopic pregnancies. As a preventative surgery however, it involves the removal of the fallopian tubes. By not removing the ovaries this procedure is advantageous to individuals who are still of child bearing age. It also reduces risks such as cardiovascular disease and osteoporosis which are associated with removal of the ovaries.
