3D modeling in reconstructive surgery of esophageal-gastric junction

Introduction. Surgical interventions in the gastroesophageal junction are complex manipulations that are often accompanied by iatrogenic complications. This is due to the specific anatomical structure of this area. Therefore, more accurate and secure methods for planning operations are required. Modern technologies, such as three-dimensional modelling, make it possible to create a personalized model of this area, which allows the surgeon to study the anatomical features of the patient in detail. This helps navigate more accurately during surgery and reduces the likelihood of complications. Purpose of the study. To demonstrate the effectiveness of using 3D modelling of the gastroesophageal junction area when performing surgical intervention for recurrent hiatal hernia. Materials and methods. The patient's MSCT was analysed by assessing the anatomical features of the area of interest. Based on this, a 3D model of the gastroesophageal junction area with an altered anatomy was provided to surgeons for planning the upcoming operation. The obtained data were subsequently compared with the intraoperative findings. Results. A patient with recurrent hiatal hernia underwent surgery with preliminary 3D modeling. No intra- or postoperative complications were observed. Considering the smooth course of the postoperative period, the patient was discharged in satisfactory condition on the 5th day after surgery. Conclusion. The use of 3D modeling in a patient with recurrent hiatal hernia enhanced intraoperative navigation, thereby preventing complications.
