[Morpho-functional characteristics of invagination esophago-enteric and esophago-gastric anastomoses].

The morphological and functional features of invagination ++esophago-enteric and esophagogastric anastomoses were studied in 234 of 266 patients who underwent gastrectomy or proximal resection of the stomach for cancer in 1972-1989. Two valuable stable properties were found to be characteristic in normally functioning invagination anastomosis: reliable anti-reflux properties and evacuation in portions. They are ensured by the obturating apparatus of the anastomosis, which consists of a valve and a muscular sphincter.

[Ultrasonic diagnosis of aneurysms of the abdominal aorta and its state after reconstructive surgery].

The article generalizes the results of examination of 44 patients for diagnosing aneurysms of the abdominal aorta and its complications with the use of the ultrasonic method. Aneurysms were detected in 27 patients, dissecting aneurysm was found in 7 of them and rupture of the aneurysm in one patient. Operation was carried out on 16 patients, all of them were kept under dynamic observation beginning from the 3rd-5th postoperative day.
