Spray-On Polymer Mats Seal Surgical Incisions

Researchers from the University of Maryland have developed a spray on bio-degradable polymer that can be used to hold surgical incisions closed, sealing and protecting them from the environment.

The film has been tested on pigs for various operations and dissolve away over a 42-day period. Clinical trials and methodology planning are in the works.

Cancer patient's leg kept alive by being attached to arm

Surgeons removed a man’s tumour and rebuilt his body using leg muscles and tissue they had removed and attached to his arm to keep alive.

"It’s not easy for a surgeon to tell a patient that they haven’t done this particular procedure before."

After 120 Years, Doctors Develop New Brain Surgery Technique

A team of surgeons from Johns Hopkins recently came up with a safer, better method of replacing skull fragments after brain surgery. This is good news for anybody who might need a little work done on their noggin in the near future, as doctors have been using the same method since the 1890s.

British doctor branded his initials on patient's liver

Artists generally like to sign their work. Painters, sculptors, poets, all leave their name as a mark of pride. But when your brush is a scalpel and your canvas is the human body, it’s probably best to avoid that urge. One British surgeon is finding that out, after being suspended for branding his initials on a patient’s liver. 

Well this is embarrassing.

Novice Neurosurgeons Train On Brains Printed In 3-D // NPR

There’s no such thing as too much practice when it comes to brain surgery.

But it’s hard for beginner neurosurgeons to get real hands-on experience. Most residents learn by watching and assisting experienced surgeons.

Newbies can practice on cadavers or use simulators, of course. But neither of those alternatives is quite the same as operating on a real, live patient, for better and for worse.

That’s why 3-D printers might help the doctors do a better job. At the University of Malaya in Malaysia, neurosurgeons are using 3-D printers to make realistic skulls and brains that residents can use to hone their skills.

The models combine different materials to mimic the feel of human bone, membrane and tissue. Each practice patient is made to order from the scans of an actual patient, so students can try the same procedures they see senior surgeons perform.

Dr. Vicknes Waran, one of the neurosurgeons working on the project, says he prefers these 3-D models over cadavers for teaching.

"In some parts of the world, it’s difficult to get cadavers," Waran tells Shots. Plus it’s hard to find a cadaver with the types of tumors and illnesses that the residents are being trained to treat. The best part, Waran says, is that students can practice on the models as many times as they need to in order to completely master a technique.

When I was waiting for test results I tried to make up a description in my mind of the consequences of a bad outcome; for myself and then for my wife and my children. For myself it maybe is not too bad - straight to the grave - which is where we all go; even if we think it is too early whenever it comes to that. It is awful, it is difficult to get used to that thought - if you ever are able to…it would be worst for my wife…she is the one who has to take the blow.

When I heard of going to the cancer clinic, I began shivering all over my body. As soon as I opened the door here I felt the smell of the house of death. I can still feel this smell. The word cancer is loaded with fear, I think, and I know some persons who have died of cancer. A tumor is a tumor; uncontrolled cell division, something growing and attacking inner organs.

I react severely to the cytotoxic drugs. I feel so sick, and although I get other drugs to subdue the vomiting, the sick feeling is there, rocking my body all the way. I feel as if I am being run over by a steamroller - my whole body is reacting.

I remember when I woke up from the operation the surgeon told me they had found “islands of outgrowths” in the peritoneum, which was negative news. Something strange happened to me; all anaesthetics and all drugs disappeared from my body, my brain become crystal- clear and I thought: “How can I tell this to my wife?
