A disadvantage with standard surgical excision is a reported higher recurrence rate of basal-cell cancers of the face, especially around the eyelids, nose, and facial structures. There is no clear approach, nor a clear research comparing the effectiveness of Mohs micrographic surgery versus surgical excision for BCC of the eye.For basal cell carcinoma excisions on the lower lip the wound can be covered with a keystone flap. A keystone flap is achieved by creating a flap below the defect and pulling it superiorly to cover the wound. This can be performed if there is enough skin laxity to cover the defect and adequate blood supply to the flap. Mohs surgery
For many new (primary) and all recurrent forms of basal cell carcinoma after previous surgery, especially on the head, neck, hands, feet, genitalia and anterior legs (shins), Mohs surgery should be considered.Mohs surgery (or Mohs micrographic surgery) is an outpatient procedure, developed by Frederic E. Mohs in the 1930s, in which the tumor is surgically excised and then immediately examined under a microscope. It is a form of pathology processing called CCPDMA, which means that the entire surgical margin (both edges and deep) is examined. During the surgery, after each removal of tissue and while the patient waits, the tissue is examined for cancer cells. That examination dictates the decision for additional tissue removal.
However, in GAVE, the ectatic blood vessels are more commonly found in the antrum or lower part of the stomach. Pathogenesis
Several studies have found that patients with portal hypertension develop increased blood flow to the stomach. The physiological findings that correlate with worsening portal hypertensive gastropathy include an increased portal venous pressure gradient and decreased hepatic blood flow. Biopsies of the stomach in patients with portal hypertensive gastropathy show ectatic (or dilated) blood vessels, evidence of bleeding by means of red blood cells in the lamina propria, and edema in the stomach wall. Treatment
Medications
Several treatment options have been developed for portal hypertensive gastropathy. The first is the use of beta-blockers, which reduce portal pressures. Non-selective beta blockers (such as propranolol and nadolol) have been used to decrease the pressure of the portal vein in patients with esophageal varices, and have been shown to regress portal hypertensive gastropathy that has been worsened by medical treatment of varices. Propranolol has also been evaluated in patients with chronic cirrhosis and portal hypertensive gastropathy. Other medications that primarily treat bleeding, including anti-fibrinolytic medications such as tranexamic acid have also been used in case reports of patients with portal hypertensive gastropathy. These medications work by stabilizing deposits of fibrin at sites that ordinarily would bleed. Finally, octreotide, an analogue of somatostatin that leads to vasoconstriction of the portal circulation, can be used for active bleeding due to portal hypertensive gastropathy. Sucralfate, a coating medication has also been used, but evidence is from animal models.
