Background:
Intraoperative complications during combined thoracoscopic-laparoscopic surgery for esophagogastric junction (EGJ) carcinoma have not been reported as compared to those during surgery for esophageal carcinoma. We present two cases which had surgery-related hemodynamic instability during laparoscopic proximal gastrectomy and intra-mediastinal valvuloplastic esophagogastrostomy (vEG) with thoracoscopic mediastinal lymphadenectomy for EGJ carcinoma.
Case Presentation:
In case 1, the patient fell into hypotension with hypoxemia during laparoscopic vEG due to pneumothorax caused by entry of intraabdominal carbon dioxide. In case 2, ventricular arrythmia and ST elevation occurred during laparoscopic vEG. Pericardium retraction to secure surgical field during reconstruction compressed the coronary artery, which caused coronary malperfusion. These two events were induced by the surgical procedure, characterized by the following: (1) connection of the thoracic and abdominal cavities and (2) cardiac displacement during vEG.
Conclusion:
These cases indicated tension pneumothorax and coronary ischemia are possible intraoperative complications specific to combined thoracoscopic-laparoscopic surgery for EGJ carcinoma.
