Surgical interventions can be done by laparotomy or laparoscopy. This can be accomplished with open abdominal surgery (laparotomy) or keyhole surgery (laparoscopy). A laparoscopy or laparotomy can also be performed to visually confirm an ectopic pregnancy. In the presence or suspected internal bleeding, surgery is indicated via laparoscopy or laparotomy. It can be performed by laparotomy or laparoscopy. In addition, laparoscopy and/or hysteroscopy may be indicated. A cholecystectomy may be an open procedure, or one conducted by laparoscopy. A laparoscopy in very early ectopic pregnancy rarely shows a normal looking fallopian tube. Diagnosis can be made using ultrasound or laparoscopy testing. Oophorectomy for benign causes is most often performed by abdominal laparoscopy. Surgery, especially adrenal laparoscopy, is the most common treatment for small pheochromocytomas. In 2008, Simon was reportedly dating Richard Koehler, a surgeon specializing in minimally invasive laparoscopy. A hysterosalpingogram, laparoscopy and dye, or hysterocontrast sonography will demonstrate whether the tubes are open. It may also occur as a result of oral surgery, laparoscopy, and cricothyrotomy. Hope reported in 1937 on the use of laparoscopy to diagnose ectopic pregnancy.
