[Pneumothorax in laparoscopic cholecystectomy (II)].

This case report deals with pneumothorax during elective laparoscopic cholecystectomy in a young woman with no history of severe pulmonary disease. After inflating the capnoperitoneum, pulse oximetry and capnography raised suspicion of pneumothorax whereas the physical examination showed no irregularities. Surgical drapes provided a lack of information from percussion and auscultation. Changing respiratory parameters including the use of pressure-controlled ventilation in absence of tension pneumothorax enabled sufficient ventilation until the insertion of a chest tube. There were no further postoperative complications. Pulse oximetry, capnography and relaxometry proved helpful in monitoring. There may be a benefit from the use of pressure-controlled-ventilation in certain situations, if all changes in volume-controlled-ventilation fail.
