Aspiration pneumonia is considered to be a morbid complication of anesthesia, It was reported that several conditions are associated with an increased frequency of aspiration pneumonia, such as gastroenterological, neurological and, pulmonary diseases. The incidence is also higher in emergency situations than during elective surgery. We encountered aspiration pneumonia after emergency laparoscopic salpingectomy. The patient was 25 years old woman with no prior medical history but had fasted for only 5 h in the preoperative period. During the perioperative period, there were no signs of regurgitation of the gastric contents into the oral cavity. After surgery, the patient was transported to the recovery room in a fully awakened state. However, the patient became cyanotic without vomiting. After physiotherapy, a chest CT scan was performed, and she was diagnosed with aspiration pneumonia. She was admitted to intensive care. Ten days later, she was discharged in a healthy state.
