Gastropleural fistula due to gastric perforation after lobectomy for lung cancer.

We report a case of acute gastropleural fistula due to gastric perforation after a left lower lobectomy for lung cancer. A 76-year-old male, who received a left hemicolectomy 20 years previously, came to our hospital for surgical treatment of lung cancer, which was performed uneventfully as a left lower lobectomy with combined resection of the diaphragm. On the postoperative day 2, acute dilatation of the stomach followed by gradual cardiopulmonary collapse, and then gastric perforation into the thorax occurred. The perforated stomach wall and diaphragm became paper-thin and necrotic, though the abdominal cavity was free of contamination. This life-threatening condition was treated by an emergency thoracotomy and partial gastrectomy through the thorax, as the left hemidiaphragm was remarkably elevated. An oeganoaxial torsion gastric volvulus caused by anatomic rotation following the lobectomy was speculated as the disease process, with loss of suspended tissue of the gastro-colic ligament from the left hemicolectomy being a possible predisposing factor. Such an episode is rare, however, it should be looked for during perioperative care following a lobectomy.
