Gallbladder removed without external incisions
In April of last year, surgeons at NewYork-Presbyterian Hospital/Columbia University Medical Center made headlines by removing a women's gallbladder through her uterus using a flexible endoscope, aided by several external incisions for added visibility. Now, they have performed the same procedure without a single external incision in what surgeons... view more... (2008-07-29)
Human Brain Connectivity Mapping
The unique connectivity pattern of a brain region determines the type of information available to it, and hence influences its function. Defining these patterns enhances our knowledge of human brain architecture and function. Non-invasive in vivo definition of brain connectivity patterns complements functional imaging and provides new... view more... (2004-09-23)
Mending meniscals in children, improving diagnosis and recovery
The meniscus is a rubber-like, crescent moon-shaped cartilage cushion that sits between the leg and thigh bone. Each knee has two menisci: one on the inside of the knee joint and one on the outside. view more (2009-11-03)
Stenting of abdominal arteries offers welcome relief for 'intestinal angina'
Using catheter techniques perfected in the arteries of the heart, interventional cardiologists are successfully treating chronic mesenteric ischemia, a condition akin to intestinal angina. view more (2007-05-14)
Invasives threaten salmon in Pacific Northwest
Many native fishes in the Pacific Northwest are threatened or endangered, notably salmonids, and hundreds of millions of dollars are expended annually on researching their populations and on amelioration efforts. view more (2009-03-02)
Smoking can harm the long-term effects of some oral surgery procedures
A study in the September issue of the Journal of Periodontology (JOP) found that smokers had less desirable long term results following periodontal plastic surgery than non-smokers. view more (2007-09-19)
Long waiting lists do not reflect a general failure of the NHS
Despite widespread political and media attention about long waiting lists, a study in this week's BMJ finds that in most instances, substantial numbers of patients waiting longer than six months for elective surgery are restricted to a small number of hospitals. Researchers at the University of Bristol examined the distribution of patients waiting... view more... (2003-01-22)
Cone-beam CT: Just as useful as MDCT before and after percutaneous vertebroplasty
Cone-beam CT which is believed to deliver less radiation than MDCT is just as useful when evaluating patients before and after percutaneous vertebroplasty according to a study performed at the Department of Clinical Radiology, Kyushu University, Fukoka, Japan. view more (2008-11-04)
Kidney cancer patients may be overtreated, U-M study finds
A less aggressive type of surgery designed to spare healthy organ tissue is used infrequently to treat early-stage kidney cancer, according to researchers at the University of Michigan Comprehensive Cancer Center. view more (2006-02-09)
Women's Cancer Outcome Improved by Surgical Evaluation
Many women scheduled to undergo hysterectomy for pre-cancerous cell changes actually need a more comprehensive surgery, something they should discuss with a gynecologic oncologist, say researchers at the University of Alabama at Birmingham (UAB). view more (2009-02-13)
Brain surgery, new light-emitting materials and medical imaging - all are covered in the December issue of Opto and Laser Europe
LASERS ON THE BRAIN A new, minimally-invasive tool that can completely remove a brain tumour through a small hole in the skull has been delivered to surgeons in Germany. Conventional techniques use lasers to destroy brain tumours by thermal effects. This can destroy healthy tissue, and increases the risk of toxic side effects because it does not... view more...

New uses for endoscopy
Braquitherapy guided by ecoendoscopy has enabled a therapeutic approach to injuries, hitherto inaccessible by other means. view more (2006-04-04)
PneuStep — MRI-safe motor makes robotic biopsies possible
Engineers at the Johns Hopkins Urology Robotics Lab report the invention of a motor without metal or electricity that can safely power remote-controlled robotic medical devices used for cancer biopsies and therapies guided by magnetic resonance imaging. view more (2007-04-09)
No Evidence That Obese People Are At Higher Risk Of Complications After Surgery (pp 2001, 2032)
Results of a prospective study in this week's issue of THE LANCET suggest that excluding obese people from surgery because of fears about postoperative complications is unjustified. Despite a lack of convincing evidence, obese people are thought to be at a higher risk of complications after surgery than those who are not obese. Pierre-Alain... view more... (2003-06-11)
Cincinnati Surgeon Leads First Test of Mobile Robotic Surgery
A team of military, telecommunications and surgical experts led by University of Cincinnati (UC) faculty are using an unmanned aircraft and sophisticated communication tools to take the next step toward making "telesurgery" a reality. view more (2006-06-06)
PREOPERATIVE RADIOTHERAPY IMPROVES OUTCOME IN RECTAL CANCER (PP 1285, 1291)
Preoperative radiotherapy reduces risk of local recurrence and death from rectal cancer, conclude authors of a systematic overview published in this week's issue of The Lancet. There are different opinions about when it is best to give radiotherapy for rectal cancer. In Scandinavia, the Netherlands, and some other European countries, radiotherapy... view more...

Surgery best option for preventing recurrence of venous leg ulcers (p 1854)
A UK study in this week's issue of THE LANCET highlights how surgery in addition to compression treatment could substantially reduce the risk of recurrent leg ulcers. Venous leg ulceration affects 1-2% of people and accounts for 1% of health costs in developed countries. Treatment includes compression, leg raising, and exercise; no randomised... view more...

Minimally invasive approach can take the pain out of herniated disks
Much like the aging face, the taut disks that cushion the spinal column, enabling us to twist and bend, become less elastic over time. view more (2006-05-02)
Cost of waiting for gall bladder surgery is high
A significant amount of NHS money is being used to treat patients with recurrent gallstone problems while they await surgery, warn researchers in Postgraduate Medical Journal. view more (2002-12-13)
Interventional radiology: From sidelines to mainstream for patients
The Society of Interventional Radiology hailed the extension of an American College of Radiology resolution in support of clinical patient management by vascular and interventional radiologists as an important reminder of the critical contribution these minimally invasive specialists bring to quality patient health care. view more (2009-05-13)
