[Hemostatic effect of an endoscopic local injection of hypertonic saline-epinephrine (HS-E) solution on upper gastrointestinal bleeding--comparative study of this effect with and without visible vessel detection].

One hundred and ninety seven patients with upper gastrointestinal bleeding were each administered and endoscopic local injection of hypertonic saline epinephrine (HS-E) solution at our hospital over a 5-year period, from the Spring of 1981 to March of 1986. Peptic ulcers were found in 162 of the patient. Vessels could be visibly detected in the 148 (91.4%)-A group, but not in the 14 (8.6%)-B group. A comparison of the number of endoscopic local injections to each of these groups indicated no significant differences in types of bleeding, systemic complications, or sites of bleeding. The excellent hemostatic effect of HS-E is due to the fact that local injection of its solution can be repeated in large quantities for various types of bleeding.

Endoscopic local injection of hypertonic saline-epinephrine solution to arrest hemorrhage from the upper gastrointestinal tract.

For the purpose of arresting hemorrhage from the upper gastrointestinal tract we developed a method of endoscopic local injection of hypertonic saline-epinephrine solution, consisting of 3.6% or 7.1% sodium chloride with 0.005% epinephrine, which was locally injected around the base of the bleeding vessel under endoscopy. During the period between October 1978 and September 1983, a total of 158 patients underwent treatment for hemostasis by this method. The major causes of bleeding in our study consisted of gastric ulcers (114) and duodenal ulcers (15). The overall effective rate of hemostasis was 98.1%. By applying this method, the rate of emergency operation for patients with bleeding from the upper gastrointestinal tract was significantly reduced from 21.7% (15/69) to 0.8% (1/128).

[Clinicopathological study on 100 Japanese patients with peritoneal mesothelioma in Japan].

We report a clinicopathological study on 100 japanese patients with peritoneal mesothelioma encountered between 1911 and 1982. Fifty-six were males and 44 were females, they ranged in age from 10 months to 83 years. As the inducement materials, asbestos was reported in 5 and thorium in 2 patients. Clinical symptoms were abdominal distension in 56 and abdominal pain in 50 patients. Thrombocytosis and hypoglycemia were observed in 7 and 3 patients, respectively. Macroscopically, the peritoneal mesothelioma was localized in 7, diffuse in 86 and not described in 7 patients. The pathological classification was benign in 5 and malignant in 77 cases. According to Stout's classification, the peritoneal mesothelioma was tubular in 43 mixed in 25 and fibrous type in 11 cases. Based on our findings we suggest that peritoneal mesotheliomas are on the increase in Japan.

[Localized fibrous malignant peritoneal mesothelioma in an operated patient with massive hemorrhage to the peritoneal cavity].

We reported an operated patient with localized peritoneal mesothelioma. The patient was a 39-year-old man who had occasionally complained of left hypochondralgia for 5 years before admission. Progressive anemia due to hemorrhage into the peritoneal cavity was noted after admission. Peritoneoscopy revealed the bleeding to be located between the left lobe of the liver and the anterior wall of the stomach. On the 22nd hospital day, surgery was performed and a fist-sized tumor was resected. Microscopically, it was fibrous malignant type of the peritoneal mesothelioma. Chemotherapy was performed 3 times after the operation, and the patient is living and well 1 year and 8 months postoperatively.
