[The importance of x-ray and endoscopic studies of the stomach in the complex examination of patients following resections and vagotomies].

X-ray and endoscopic examinations were made in the course of follow-up of patients surgically treated for gastroduodenal ulcer (n = 134). X-ray investigations of postoperative stomach make it possible to assess it functionally, to determine its relations with other parts of gastrointestinal tract. Endoscopy is helpful in revealing changes in gastric mucosa, anastomosis capable of producing diverse motor and evacuatory disturbances of the stomach. The methods are recommended in postoperative follow-up as these can identify early abnormalities and give information for relevant correction. The correction made by the authors resulted in a decrease in temporary disability by 2-3 weeks and in unfavorable outcomes from 17.2 to 4.3%.
