BACKGROUND: Perfusion scans are accurate predictors of postoperative lung function. There are few previous studies aimed at predicting the postoperative exercise capacity using the perfusion scanning and those that did reported contradictory results. METHOD: We prospectively studied the preoperative spirometric, exercise tests and perfusion scans from in 49 consecutive patients who were admitted to Inha University Hospital with surgically resectable lung cancer from Jan. 1998 to Jun. 1999 29 patients who had any condition affecting the lung function and exercise capacity, or refused a surgical resection or a follow-up study were excluded. Spirometric and exercise tests were performed 6 months after operation in 20 patients. RESULTS: The predicted postoperative FEV1, FVC and TLC correlated well with the following corresponding postoperative values : γs and p value, 0.809 and 0.000 for the FEV1 ; 0.895 and 0.000 for the FVC ; 0.741 and 0.006 for the TLC, respectively. The measured postoperative exercise values were slightly higher than the postoperative exercise values predicted, VO(2max) and Wr(max), were as 112% of VO(2max) predicted and 119% of WR(max) predicted. The change in FEV1, FVC and TLC had a weak correlation with the change in VO(2max) and WR(max). CONCLUSION: The perfusion scan was a useful tool for predicting the postoperative exercise capacity. However, they had a tendency to underestimate the exercise capacity, especially in the patients who had a pneumonectomy. A weak correlation between the change in lung function and exercise capacity was obseved.

Colonic angiodysplasia is important because of the likelihood of lower gastrointestinal tract bleeding, either massively or chronically. A 66-year-old male patient visited our hospital because of hematochezia and lower abdominal discomfort. He underwent colonoscopy, which revealed 0.5 cm sized, cherry red colored, branching, ozzing vessel with fern-like margin on cecum. Although he received endoscopic injection therapy with hypertonic saline and oral estrogen-progesterone therapy, subsequent ileocecal resection was performed due to recurrent bleeding. Histology of the resected specimen showed irregularly dilated, distorted, thin-walled vessels in submucosa.

Small Cell Lung Carcinoma*

Primary hemangiopericytomas of the lung are uncommon sarcomas that arise from pericytes that surround the basement membrane of capillaries and small venules within the lung parenchyma. The presenting symptoms and signs depend on the location of the tumor and radiologic features are not diagnostic. The behavior of pulmonary hemangiopericytomas is difficult to predict and all tumors should be considered potentially malignant. Wide surgical excision remains the mainstay of treatment. We report a case of primary hemangiopericytoma of the lung with a brief review of literature.

Lymphangioleiomyomatosis is a rare disease which afflicts young women of childbearing age. We experienced a 32-year-old female who was admitted because of worsening exertional dyspnea after hormonal therapy with Clomifen for five months and intermittent hemoptysis. Chest PA showed diffuse ground glass appearance with some reticular infiltrations. High resolution CT scan showed multiple small thin walled cysts distributed homogeneously throughout the entire lung. Pulmonary function test showed characteristic obstructive pattern despite the restrictive interstitial pattern of chest radiography. Thoracoscopic lung biopsy specimen showed abnormal proliferation of smooth muscle cells in the walls of lymphatic vessels, bronchioles, and pulmonary vessels typical of pulmonary lymphangioleiomyomatosis. Hormonal therapy with medroxyprogesterone was initiated.

BACKGROUND: Primary malignant tumors of the trachea are extremely rare entities and account for a mere 0.1 percent of all malignancies of the respiratory tract Because of vague localizing signs, symptoms and a usually negative routine chest film, the patients with tracheal tumors are often treated for asthma or chronic obstructive pulmonary disease for considerable period of time before correct diagnosis. METHODS: We Have made a review of the 17 cases of primary tracheal tumors in recent 15 years. We reviewed the clinical features including history of smoking arid respiratory symptoms, the official readings of initial routine chest film, the cytologic examination of sputum, the time of delay in diagnosis, and the response according to the therapeutic modalities. RESULTS: Eight out of 9 patients with squamous cell carcinoma(SCC) were above 50 years old, five out of 6 patients with adenoid cystic carcinoma(ACC) were below 50 years old. The most common location of primary tracheal tumors was the upper one-third of trachea in 8 cases(47%). The most frequent symptoms were dyspnea in 13/17 cases(76%) and then strider or wheezing, cough, and sputum in order. The routine chest roentgenographic examinations wore not helpful to diagnose tracheal carcinoma and the cytologic examinations of sputums were helpful to diagnose tracheal carcinoma in only one case with adenocarcinoma. The mean times of delay in diagnosis of patients with SCC and ACC were S months and 24.9 months respectively. We bad bronchial asthma in 8 cases(47%) and tracheal tumors in 4 cases(23%) as initial clinical impression CONCLUSION: We would like to perform more comprehensive diagnostic too]s(high KVP technique, the fibroptic bronchoscopic examination, chest CT scan etc.) in patients who had the suggestive points for the tracheal tumors(1. unexplained hemoptysis or hoarsness, 2. inspiratory wheezing or stridor, 3. wax arid waning of dyspnea according to changes of position. 4. progressive asthmatics unresponsive to antiasthmatic therapy) and radical resection of tumor or external radiation therapy with curative aim as possible.
