Preoperative X-ray computerized tomography (CT) was performed in 60 patients with carcinoma of the esophagus at the All-Union Oncology Research Centre, USSR AMS in 1986-1989. The method is evaluated on the basis of comparison with the operative findings in determining the depth of invasion of the esophageal wall and adjoining structures by the tumor, metastatic involvement of the lymph nodes below the diaphragm, and metastases in the liver. Informativeness of X-ray CT proved to be highest in patients in whom the tumor had not spread beyond the esophageal wall. It was established that the method possesses high resolving possibilities in identification of enlarged lymph nodes in the abdominal cavity. Small metastases in the liver, measuring 0.5 to 2 cm in diameter, cannot be revealed by the method in some cases. The data gained by means of X-ray CT allows tactics of the surgical intervention to be determined and the late-term results to be predicted.

Pulmonary vein anatomical variations are frequently observed in atrial fibrillation patients undergoing catheter ablation. However, when it comes to patients with atrial fibrillation and bilateral common ostium in the inferior pulmonary veins, using a bilateral circumferential pulmonary vein isolation approach during catheter ablation heightens the risk of esophageal injury. At present, there is no established standard catheter ablation strategy for such cases.

Aim: In the study, we aimed to introduce a formula for measuring the oesophageal total wall thickness area, which could be used for developing an artificial intelligence-based algorithm for the detection of patients whose total wall thickness area exceeds the norms.
Material And Methods: Mathematical formulas for measuring the square area of the oesophageal total wall thickness area were introduced and applied. Children were grouped according to their weight in clusters.

Introduction: Roux-en-Y gastric bypass (RYGB) reversal might be necessary to alleviate refractory surgical or nutritional complications, such as postprandial hypoglycemia, malnutrition, marginal ulceration, malabsorption, chronic diarrhea, nausea and vomiting, gastro-esophageal reflux disease, chronic pain, or excessive weight loss. The surgical technique of RYGB reversal is not standardized; potential strategies include the following: (1) gastro-gastrostomy: hand-sewn technique, linear stapler, circular stapler; (2) handling of the Roux limb: reconnection or resection (if remaining intestinal length ≥ 4 m).
Case Presentation: We demonstrate the surgical technique of a laparoscopic reversal of RYGB with hand-sewn gastro-gastrostomy and resection of the alimentary limb with the aim of improving the patient's quality of life.
Mechanism and management of aorto-oesophageal fistulation after thoracic endovascular aortic repair.

An aorto-oesophageal fistula (AOF) is a pathological communication between the thoracic aorta and the oesophagus. It can induce life-threatening hematemesis, which is unique among the other types of gastrointestinal haemorrhage in that the vomiting is bright red and represents an arterial bleed. Nevertheless, it is notable that over 70% of cases are associated with thoracic aortic aneurysms, particularly as a postoperative complication following open surgery, and arguably more so following endovascular repair.

Background: The use of mesh in the repair of large hiatal hernias is still controversial. One of the most feared adverse events related to the use of mesh is erosion into the esophageal and gastric walls.
Aims: To record the endoscopic treatment of mesh that has migrated into the gastric lumen after surgical treatment of hiatal hernia.
