Cancer of the larynx (vocal cords cancer)
Cancer of the larynx (vocal cords cancer) M_Nabil 17,193 Views • 2 years ago

This endoscopy shows a patient with cancer of the larynx, Laryngeal cancer is the most common cancer of the upper respiratory tract. The incidence of laryngeal tumors is closely correlated with smoking, as head and neck tumors occur 6 times more often among cigarette smokers than among nonsmokers. The age-standardized risk of mortality from laryngeal cancer appears to have a linear relationship with increasing cigarette consumption. Death from laryngeal cancer is 20 times more likely for the heaviest smokers than for nonsmokers. It should be suspected in any patient with hoarseness of the voice for three weeks or longer until proven otherwise.

Transoral Access in Endoscopic Thyroid Surgery

Transoral Access in Endoscopic Thyroid Surgery Background: The number of patients demanding endoscopic neck surgery is rising. The access trauma of the axillary, breast and chest approaches is bigger than in open or video assisted surgery. We tested the feasibility of he sublingual transoral access which is in our opinion the only real minimally...-invasive extracollar endoscopic access to the thyroid gland Methods: We performed an experimental investigation in a porcine model. In 10 pigs we made 10 endoscopic transoral thyroidectomys with a modified axilloscope with the help of ultrasonic scissors and a neuro-monitoring system for identification of the recurrent laryngeal nerve. Results: The average operation time from the introduction to the removal of the obturator just above the larynx was 57 seconds. The mean operation time was 43 minutes. With the help of the neuro-monitoring system we proved in all cases the function of the recurrent laryngeal nerve on both sides. The pigs were observed for another two hours after operation. During and after the operation no complications appeared. Conclusions: We could show that the endoscopic transoral thyroid resection in pigs is possible and save. Our results might be useful for using this access for endoscopic thyroid resection in humans.

Diverticulosis of the Colon
Diverticulosis of the Colon Mohamed 25,429 Views • 2 years ago

The colonoscope is slowly withdrawn during this screening colonoscopy down from the transverse colon, back around the splenic flexure, and down the descending colon, and reveals this finding a colonic diverticula. Diverticulosis is a common, acquired, age-related occurrence affecting over 50% of the... western adult population over the age of 50. It is seen rarely in Africa and Asia where the dietary fiber content is traditionally higher. Thus most investigators feel that low fiber diets are related to the development of this condition. Ironically, colonic diverticula are not true diverticula but rather pseudodiverticula in that the sac includes layers of the mucosa and submucosa that push through rather than include the outer muscular layer. As with the small bowel the colon has an inner circular muscular layer, but the outer longitudinal layer is composed of three bands of muscle that run the length of the colon known as teniae. Diverticula occur in rows between the mesenteric and two antimesenteric teniae where the colonic wall is further weakened by the defect caused by the perforating vasa recti artery which supplies the colonic mucosa. Occasionally, the anatomic propensity of diverticula to form in rows is quite apparent as seen when this clip is replayed in slow motion. Most often, however, the arrangement of the diverticula appears random due to the angulation of the bowel and thickening of the semi lunar folds. The conditions that cause these pulsion diverticula are not know with certainty but may include high intrahaustral pressures, muscular hypertrophy, and age related alterations in collagen cross linking. Diverticula can bleed or can abscess and perforate. The incidence of diverticulitis or diverticular bleeding is in the range of 1:1,000 patients with diverticulosis.

Anchoring suture of esophagojejunostomy after total gastrectomy

Next to esophagojejunostomy stapling for the reconstruction following total gastrectomy, several silk stitches anchoring the jejunum to endoabdominal fascia are made to restore the function of phrenoesophageal ligament.
anchoring suture reduces the impairment of the anastomotic blood flow that is caused by gravitational tension and so is useful to protect the esophagojejunostomy after total gastrectomy.

Purpose The complication rate in patients treated with the Linton procedure was unacceptably high. SEPS is minimal invasive treatment modality for chronic venous insufficiency and venous ulcers. Materials and Methods252 limbs of 229 patients who underwent SEPS procedure and/or safenous vein ablati...on from May 2003 to January 2008. Tourniquet was not used and two-port technique was preferred for operation. Skin graft was not used. Honeysoft (medical honey) was used for wound care in selected cases. Results According to CEAP clinical Classification 112 limbs were class 6, 70 limbs (class 5), 70 limbs (Class4) respectively. Greater saphenous vein stripping and/or high ligation, and varicose vein excision accompanied SEPS in 241limbs who had combined Sapheno-femoral junction and perforator vein insufficiencyand SEPS was performed alone 23 limbs who had recanalised deep venous thrombosis (19) and PVI alone(4). Mean patient follow-up was 35 months. No early deaths or thromboembolism occurred. Complications included severe subcutaneous emphysema(1), neuralgia (7), 1 year later cellulites (1). Ulcers healed in 124 limbs in two months and 58 limbs in 3 months. ulcer recurrence was seen on 12(%6.6) limbs. Clinical severity and disability scores improved significantly after surgery. Conclusion All venous ulcers healed with SEPS combined or not ablation of superficial venous reflux and remain healed 5 year period and symptom-free except recurrent ulcers during the long-term follow-up. SEPS is an effective and safety treatment modality.

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%.

University Hospitals Neurological Institute will host a live webcast to demonstrate the removal of a brain tumor that doctors believe is causing epileptic seizures in a middle-aged man.

An MRI showed what appears to be a glioma (tumor) near a part of the brain that controls muscle movement, called the motor strip. Studies have shown that complete removal can cure the seizures and improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because it's difficult to determine where tumor ends and normal brain begins.
