Maintaining sufficient blood flow to the gastric tube after a subtotal esophagectomy for esophageal cancer is crucial for decreasing the esophagogastric anastomotic leakage. After subtotal esophagectomy for esophageal cancer, to additionally revascularize the gastric tube using the splenic artery a...nd vein, external carotid artery, and internal jugular vein, the supercharge technique was performed in esophageal reconstruction patients. Operative results of these patients (supercharge group) were retrospectively compared with those of patients not receiving the technique (control group). Both operation time and operative blood loss in the supercharge group were significantly longer and larger than those of the control group. However, the incidence of anastomotic leakage was significantly lower in the supercharge group than in the control group, and a 30-day reduction in the mean postoperative hospital stay was achieved with the supercharge group. This practical supercharge technique could be a breakthrough less to reduce leakage during esophageal anastomosis.

The colonoscope is slowly withdrawn during this screening colonoscopy down from the transverse colon, back around the splenic flexure, and down the descending colon, and reveals this finding a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.

LASIK Surgery Procedure

Microkeratome in Lasik

LASIK or Laser-Assisted In Situ Keratomileusis is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses.

LASIK surgery is most commonly performed as a cure for myopia (nearsightedness), but can also be used to cure hyperopia (farsightedness) or astigmatism (corneal irregularities).

LASIK is a procedure that permanently changes the shape of the cornea using a special laser and thus focusing the light rays exactly on the retina.

The steps of the procedure are as follows:

A suction ring is placed on the eye to stabilize and check the eye pressure.

The microkeratome, a cutting instrument, is attached to the suction ring.

The blade of the microkeratome is used to cut a flap in the cornea.

The exposed inner layer of the cornea is then reshaped with an excimer laser.

The corneal flap is returned to its original position.

LASIK is an ambulatory procedure; the patient can walk into the surgery center, have the procedure and walk out again and is awake the whole time. Occasionally, the doctor may administer a mild oral sedative.
