The incidence of gastric ulcer in hiatal hernia is highest in para-esophageal hernia and in chronic incarcerated hernia in older patients. Two patients with chronic incarcerated sliding hernias complicated by unrecognized gastric ulceration and perforation are described. One patient developed a subhepatic and mediastinal abscess; the other developed a gastropleural fistula. The incidence, clinical and roentgen findings, complications, and treatment of gastric ulcers in hiatal hernia are discussed.

Two cases of intestinal neurofibromas which were demonstrated during mesenteric arteriography are described. In 1 patient, tumors located in the jejunum and distal ileum were the apparent source of gastrointestinal bleeding. In another case, a neurofibroma of the proximal jejunum was an incidental finding during evaluation for severe pancreatitis and bleeding from esophageal varices.
