SCOOP transtracheal oxygen is indicated for patients with chronic hypoxemia which persists in spite of optimal medical therapy. Arterial blood gases obtained while breathing room air should show a PaO2< 55 mm Hg. SCOOP transtracheal oxygen is also indicated for patients with a PaO2 of 56-59 mm Hg ...

if they also have: 1) dependent edema suggesting congestive heart failure, 2) "P" pulmonale on EKG (P wave greater than 3mm in standard leads II, III or AVF), or 3) erythrocythemia with a hematocrit of >55%.

Diabetes contributes to Perio Disease

Laparoscopy in acute bowel obstruction following previous surgery is a difficult procedure and avoided by most of the surgeons due to the difficulty in obtaining pneumoperitoneum, port placement, lack of working space, adhesions and risk of bowel injury.
Here is a patient who had a previous laparotomy for trauma with a midline incision from xyphysternum to pubis; after unsuccessful conservative management he underwent a laparoscopy; a prior CT scan showed adhesions in the left side and a distal-mid small bowel obstruction. The pneumoperitoneum was obtained with the Visiport placed in the right lower quadrant; although the abdomen was grossly distended, under significant tension and distended loops of small bowel were occupying most the peritoneal cavity, with muscle relaxation there is usually enough space to perform a thorough inspection of the abdominal cavity. Port placement has to be done with special care as there is no room to push and usually a blunt trocar directed away from the bowel is employed in my practice. The collapsed loops of small bowel point quickly to the site of obstruction -- it is better to avoid manipulating the distended bowel as it is heavy, oedematous and prone to be lacerated with the instruments; once the pathology is identified, in this case the obstructive band, light packing is performed in order to expose the working space and protect the bowel from instruments like scissors or diathermy. In this case the band adhesion was slightly more difficult to separate from the bowel and required a combination of sharp and gentle blunt dissection.
Once the obstruction is release and the transit of contents is confirmed in the collapsed bowel the procedure is terminated. No abdominal drainage is usually necessary.

Oral Surgery and Dental Implants

This video demonstrates the approach to a large base of tongue tumor, which was invading the ramus of the mandible. The procedure, named after Dr. Trotter, is really a median labiomandibuloglossotomy. In this case this poorly differentiated tumor was resected along with a portion of the floor of mouth. The entire area was reconstructed with a pectoralis major myocutaneous flap.

Video shows a Hip resurfacing operation done using the Durom hip from Zimmer.
The patient is a young active male. Hip resurfacing is emerging as the surgical procedure of choice in young and active patients for pain relief from Hip arthritis.

A thin polymer film that seals surgical wounds could make sutures a relic of medical history.

Measuring just 50 microns, the film is placed on a surgical wound and exposed to an infrared laser, which heats the film just enough to meld it and the tissue, thus perfectly sealing the wound. Known as Surgilux, the device's raw material is extracted from crab shells and has Food and Drug Administration approval in the US
