A-D: A patient (29-year-old male) in the study group (A: Preoperative computed tomography (CT) scan showing complete displacement of the stomach into the mediastinum and its rotation; B: Preoperative contrast X-ray of the same patient; C: Postoperative contrast X-ray of the patient on the fourth postoperative day after the open procedure. The orange arrow shows the air-fluid level in the mediastinum; D: Postoperative contrast X-ray image of the patient on the 60^th postoperative day after the open procedure. There was no air-fluid level left in the mediastinum); E-H: A patient (64-year-old female) in the study group (E: Preoperative CT scan showing complete displacement of the stomach into the mediastinum and its rotation; F: Postoperative contrast X-ray of the patient on the fourth postoperative day after the laparoscopic procedure. The orange arrow shows the air-fluid level in the mediastinum; G: Postoperative contrast X-ray image of the patient on the 25^th day after the laparoscopic procedure. The orange arrow shows the air-fluid level in the mediastinum; H: Postoperative CT scan of the patient at 12 months after the laparoscopic procedure. There was no pathologic content left in the mediastinum); I-L: A patient (68-year-old female) in the control group (I: Postoperative X-ray of the patient on the fifth day after laparoscopic hernia repair with removal of the hernia sac; J: Preoperative CT scan showing complete displacement of the stomach into the mediastinum; K: Postoperative CT scan of the patient on the fifth day after laparoscopic hernia repair with removal of the hernia sac. The orange arrow shows the effusion in the mediastinum; L: Postoperative CT scan of the patient on the fifth day after laparoscopic hernia repair with removal of the hernia sac.
