This is the biggest known operation ever.The Whipple procedure(pancreatoduodenectomy) is the most common operation performed for pancreatic cancer and may be used to treat other cancers such as small bowel cancer. Surgeons remove the head of the pancreas, most of the duodenum (a part of the small intestine), a portion of the bile duct and sometimes a portion of the stomach. After the pancreatoduodenectomy, the surgeon reconstructs the digestive tract. At Mayo Clinic, surgeons perform more than 100 Whipple procedures annually. Patients leave the hospital in an average of 14 days.

Human ovulation captured on film

To record the sequence, Stephan Gordts and Ivo Brosens of the Leuven Institute for Fertility & Embryology in Belgium performed transvaginal laparoscopy, which involves making a small cut in the vaginal wall and observing the ovary with an endoscope.

"This allows us direct access to and observation of the tubo-ovarian structures without manipulation using forceps," says Gordts.

For the photos of ovulation, which only accidentally captured the critical moment, Jacques Donnez at the Catholic University of Louvain (UCL) in Brussels, Belgium, used gas to distend the organs for photography. However, Gordts and Brosens planned the procedure to coincide with ovulation and used saline solution to "float" the structures.
Perfect timing

Observation was timed for the day of the peak of the patient's luteal hormone cycle. Ovulation was predicted to occur on the evening of the day of the LH peak, and the endoscope introduced at 6 pm.

A small amount of saline was used to float the opening of the fallopian tube, its fimbriae (the "fingers" that sweep the egg into the tube) and the ovary itself. This gives a more natural appearance than gas, says Gordts.

In the video, the fimbriae can be seen sweeping in time with the patient's heartbeat. A mucus plug can be seen protruding from the ovary – this contains the egg.

"The ovum is not captured 'naked'," says Gordts. "There is no eruption like a volcano."

Gordts says that in clinical practice it is not easy to organise the observation of ovulation. "We were probably lucky to be successful at our first attempt," he says.
