[Radiological and clinical aspects of resection of the cardia].

Following resection of the cardia, problems may arise during two phases; in these, clinical and radiological examination may be required. Immediately after the operation one is concerned particularly with checking the incision or the extent and localisation of suture abnormalities. In the late post-operative period the problems are different. In addition to a description of the anatomy at the proximal and distal ends of the stomach, it is necessary to estimate functional conditions, such as passage through the anastomosis and the pylorus, the reservoir function of the gastric remnant and gastro-oesophageal reflux. An important task is to demonstrate tumour recurrence. For this purpose endoscopic, biopsy and cytological examinations are required.
