[The choice of the surgical treatment method in gastric and duodenal peptic ulcer].

Operations were carried out on 966 patients for gastric ulcer (GU) and duodenal ulcer (DU); the ages of 78% of them ranged from 31 to 50 years. 241 patients underwent operation for GU. Stenosing ulcer was found in 21.4%, penetrating ulcer in 37.3%, bleeding ulcer in 29%, perforating ulcer in 8.3%, and ulcer-tumor in 3.4% of patients. Resection of the stomach after Billroth I was conducted in 32.2%, pyloric preserving resection in 43.1%, Spasokukotskiĭ-Finsterer operation in 5.7%, and selective proximal vagotomy with excision of the ulcer in 19% of patients. DU was found in 725 patients. The ulcer was stenosing in 42.2%, penetrating in 37%, bleeding in 14.7%, and perforating in 6.1% of patients. The following operative interventions were performed: gastric resection after Spasokukotskiĭ-Finsterer, selective proximal vagotomy and pyloroplasty, selective proximal vagotomy, Billroth I operation, excision of the ulcer and selective proximal vagotomy, stitching of the vessels. The long-term results were good in 94.5% of patients.

[Treatment of hemorrhoids with sclerosing solutions].

From 1968, the authors treated under ambulatory-polyclinical conditions 10,000 patients with hemorrhoids by means of injections of novocaine++-alcoholic mixtures. In 93.3% of the patients after injections, the hemorrhage stopped, in 83.8%--hemorrhoidal nodes didn't prolapse, in 95.6%--inflammation was liquidated. At the long-term period, the positive effect was noted in 8664 (92.2%) patients.

[Blood coagulation in patients with thyrotoxicosis before and after surgery].

A study is presented of the state of the blood coagulation system in 108 patients with thyrotoxicosis before the operation and on the 1-8 days after surgery. It was established that with increase of the severity of thyrotoxicosis hypocoagulation develops due to reduction of the procoagulant and increase of the fibrinolytic activity of the blood, disorders of the thrombocytic hemostasis component. The first 8 days after the operation are characterized by the prevalence of hypercoagulation changes. For preventing thrombohemorrhagic complication it is necessary before and after the operation to control blood coagulation and initiate adequate correction when necessary.
