  • Purpose: The purpose of this study was to investigate differences between a pulmonary aspiration group and a non-pulmonary aspiration group in glucose concentration of tracheal secretions by measuring time and feeding methods. Method: The subjects were 36 ICU patients who were receiving formula via nasogastric tubes and had endotracheal tubes or tracheostomy tubes. Tracheal secretions were collected by connecting suction traps to a suction catheter in three different times(within 1 hour after feeding, between 1 to 2 hours after feeding, and between 2 to 3 hours after feeding) for 2 days, overall six times. Glucose concentration of tracheal secretions was measured with the glucometer(Accucheck II). Results: Glucose concentration of tracheal secretions increased in progression after feeding. The mean of specimens collected last(between two to three hours after feeding) was shown to be the highest value(M=61.61mg/dl) in the pulmonary aspiration group. Significantly(p=.000) more subjects(94.44%) in the pulmonary aspiration group received formula via a 50cc syringe than those in the non-pulmonary aspiration group(22.22%). Conclusion: Critically ill patients may need more time for head-elevation after tube feeding to prevent pulmonary aspiration. In practice, enteral formula should not be given the patients via a $50_cc$ syringe anymore, instead a feeding bag or infusion pump should be used to prevent pulmonary aspiration.

  • Carcinsarcoma is an uncommon pulmonary malignancy characterized by carcinmatous parenchyma and sarcomatous stroma. The cytologic, immunohistochemical and ultrastructural features of a case of pulmonary carcinosarcoma suspected by fine needle aspiration cytology is presented. Only bizarre spindle cells arranged in loose groups, in microtissue fragments and in a dissociate fashion were present on the aspiration smears. They were markedly positive for vimentin. The epithelial component was not found, which was probably due to marked paucity of carcinomatous component that was proved by histologic examination of the resected tumor. The diagnosis of pulmonary carcinosarcoma should be conidered whenever poorly differentiated epithelial ceil groups with a malignant mesenchymal component set in a myxoid background are seen in a pulmonary cytology specimen.

  • We report a case of pulmonary aspiration during induction of general anesthesia in a patient who was status post esophagectomy. Sudden, unexpected aspiration occurred even though the patient had fasted adequately (over 13 hours) and received rapid sequence anesthesia induction. Since during esophagectomy, the lower esophageal sphincter is excised, stomach vagal innervation is lost, and the stomach is flaccid, draining only by gravity, the patient becomes vulnerable to aspiration. As the incidence of perioperative pulmonary aspiration is relatively low, precautions to prevent aspiration tend to be overlooked. We present a video clip showing pulmonary aspiration and discuss the literature concerning the risk of aspiration and its preventive strategies.

  • Purpose: This study was performed to test the clinical usefulness of the glucose test strip method for early detection of pulmonary aspiration in tube fed patients. Method: The subjects for the study were 36 patients who were receiving enteral feedings and 39 patients who were not given enteral feedings. For the analysis, the tube fed patients were divided into two groups (clinically significant aspiration and no aspiration) according to criteria. Result: The mean glucose concentration of tracheal secretions from non enteral fed patients was 26.35mg/dl and were lower than those concentrations found in tube fed patients (32.75mg/dl). The mean glucose concentration of the aspiration group was 45.60mg/dl and the glucose concentration of the non aspiration group was 19.93mg/dl. The difference was statistically significant (t=2.163, p=.038). More subjects in the no aspiration group ($73\%$) than the aspiration group ($56\%$) had glucose concentrations below 20mg/dl. After deleting the cases that had samples containing blood, glucose concentrations of tracheal aspirates were lower in both groups. Conclusion: The glucose level of the aspiration group was significantly lower than the no aspiration group and more subjects in the aspiration group had a glucose level higher than 101mg/dl. Therefore, the glucose test of tracheal secretions in tube fed patients could be a desirable test for screening for tracheal aspiration. Especially the patient who is showing repeatedly high glucose levels should not be given feedings until reassessment is completed.

  • Pulmonary amyloid deposition generally occurs with concurrent primary systemic amyloidosis. Localized forms of pulmonary amyloidosis are rare and appear most frequently as an incidental finding on chest radiographs. We present a case of nodular pulmonary amyloid tumor suggested by fine needle aspiration cytology(FNAC) and confirmed by histology examination with the polarizing light microscopy. A 41-year-old woman presented with ill-defined nodules. In the middle and lower lobes of both lungs. FNAC of the nodules revealed waxy, acellular amorphous fragments. Thoracotomy for diagnosis may be avoided by FNAC diagnosis of this unusual lesion.

  • Pulmonary hamartoma is the most common benign tumor of the lung but rarely encountered in routine cytologic work-up. We recentely experienced a case of fine needle aspiration cytology of pulmonary hamartoma in a 65-year old male patient. The characteristic cytopathologic features were 1) The mesenchymal components with cuboidal epithelial cells in a clean background, 2) The presence of fibromyxoid mesenchymal component composed of fibroblasts in a loose fibrillary stroma, and 3) Antler-liker fibromyxoid cluster having the rimming of epithelial cells which correspond to the epithelial glowing in cleft-like fashion in pulmonary hamartoma.

  • Pulmonary hamartomas are uncommon benign tumors, usually discovered radiologically as a solitary coin lesion in asymptomatic individual. The approach to the patient with a peripheral lung nodule has changed with the increasing acceptance of fine needle aspiration cytology(FNAC) as a rapid, safe, inexpensive, and highly accurate diagnostic tool. However, a few reports describing the FNAC findings of pulmonary hamarioma have appeared in the cytologic literature and the experience of FNAC is limited. We reviewed all 9 cases of pulmonary hamartoma with histologic confirmation after FNAC seen at Asan Medical Center since 1995 to evaluate cytologic findings and to determine the value of FNAC in identifying that lesion. Originally, seven of nine patients were diagnosed as pulmonary hamartoma, while two patients were diagnosed as inflammatory lesion and adenocarcinoma of each. On review, eight of nine patients were considered as diagnostic of pulmonary hamartoma. The diagnostic findings in FNAC of pulmonary hamartoma were the presence of fibrillary myxoid tissue with spindle cells as well as hyaline cartilage.

  • Thoracoscopic needle aspiration is a good alternative for a centrally-located solitary pulmonary nodule (SPN) suspected of being lung cancer without severe pleural adhesion. The authors report the technique of thoracoscopic needle aspiration biopsy in a SPN just in the medial aspect of the truncus anterior pulmonary artery and the right upper lobe bronchus.

  • Purpose: Chronic pulmonary disease may be caused by aspiration of gastric contents secondary to gastroesophageal reflux. At present, there is no gold standard for documenting pulmonary aspiration. The purpose of this study was to investigate the usefulness of radionuclide scintigraphy in the detection of gastroesophageal reflux and pulmonary aspiration. Methods: Thirty-five patients with suspected aspiration pneumonia, and five normal control subjects, were included in the study. All subjects underwent gastroesophageal reflux scintigraphy after the ingestion of a $^{99m}Tc$-tin colloid mixture. Dynamic images to detect gastroesophageal reflux were obtained for 1 hour. Additional static images of the chest, to detect lung aspiration, were obtained at 6 and 24 hours after oral ingestion of the tin colloid. In addition to visual analysis, pulmonary aspiration was quantitated by counting the number of pixels labeled with radioactive isotope in the region of interest (ROI) of both lung fields. Aspiration index (AI) was obtained by subtracting the pixel counts of the background from the pixel counts of the ROI. Results: Among 35 patients with suspected aspiration pneumonia, 23 proved to have gastroesophageal reflux by scintigraphy. One patient showed definite pulmonary accumulation of activity by visual analysis of the 6-hour image. Thirty of 35 (85.7%) patients showed higher AI beyond the upper limit of AI in the healthy controls. When we compared the reflux group with the non-reflux group, there was a significantly higher AI at 6 hours in the reflux group (p<0.05). Conclusion: The results suggest that radionuclide scintigraphy is useful in detecting small pulmonary aspiration in patients with suspected aspiration pneumonia secondary to reflux.
