Patients benefit from minimally invasive procedures
Laparoscopic cholecystectomy, a minimally invasive procedure to remove the gallbladder, is one of the most common abdominal surgeries in the U.S. Yet medical centers around the country vary in their approaches to the procedure with some moving patients quickly into surgery while others wait.

In a study published online Monday in the American Journal of Surgery, researchers found gallbladder removal surgery can wait until regular working hours rather than rushing the patients into the operating room at night.
"The urgency of removing the gallbladder is a topic of much debate among medical professionals," said Dennis Kim, MD, a Los Angeles Biomedical Research Institute (LA BioMed) lead researcher and author of the study. "We found patients who underwent the surgery during normal working hours were more likely to have the minimally invasive surgical procedure than those undergoing the procedure at night. Those undergoing nighttime surgeries – to a greater extent – experienced more invasive gallbladder removal."
The gallbladder is a pear-shaped organ on the upper right side of the abdomen that collects and stores bile, a digestive fluid produced by the liver. Gallbladders may need to be removed from patients who suffer pain from gallstones that block the flow of bile.
In a laparoscopic cholecystectomy, surgeons insert a tiny video camera and special surgical tools through small incisions in the abdomen to remove the gallbladder. Occasionally, surgeons may need to create a large incision to remove the gallbladder, and this is known as an open cholecystectomy.
For the American Journal of Surgery, the researchers conducted a retrospective study of 1,140 patients at two large urban referral centers who underwent gallbladder removal surgeries. They found 11% of the surgical procedures performed at night (7 a.m.-7 p.m.) were converted to the more invasive procedure, open cholecystectomies. Only 6% of those who underwent the surgery during the day required the more invasive form of surgery.
The researchers found no significant differences in the length of stay or complication rates. But they said the complication rates were difficult to measure because of the lack of follow-up records for the patients after they left the hospital.
Research funding was partially supported by H.H. Lee Research Award. Others who participated in the study were: LA BioMed researchers Andrew T. Nguyen, MD; Christian de Virgilio, MD, and David S. Plurad. Other researchers were from Olive View Medical Center and the David Geffen School of Medicine at UCLA: Amy H. Kaji, MD, PhD; Edward Gifford, MD; Darin Saltzman, MD; James X. Wu, MD; Reed Ayabe; Michael de Virgilio, and Virginia Nguyen.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
