Background
Chylothorax is a rare but well-known complication of general thoracic surgery. This study evaluated our treatment strategy for postoperative chylothorax and identified associated predictors.Methods
We retrospectively reviewed 1235 patients who underwent lung resection and systematic mediastinal lymph node dissection for primary lung cancer at our department from January 2008 to September 2012. Postoperative chylothorax patients were analyzed. Chylothorax was diagnosed by the milky aspect of drainage fluid and confirmed by an elevated triglyceride level (>110 mg/dL) in the drainage fluid. We initially treated chylothorax patients conservatively with low fat diet (fat intake < 20 g/day). If this treatment was judged to be ineffective, we tried to do complete oral intake cessation or surgical intervention. Comparisons between conservative and surgical intervention groups were analyzed using Fisher’s exact test. Univariate and multivariate analysis of predictors for surgical intervention was performed using logistic regression analysis. Value of p<0.05 were considered statistically significant.Results
Fifty patients (4.0%) developed postoperative chylothorax. There were 35 men and 15 women with a median age of 63 years (range 33 to 81 years). The operative procedures were pneumonectomy in 2 cases, bilobectomy in 5 cases, lobectomy in 32 cases, segmentectomy in 1 case, and sleeve lobectomy in 10 cases. Forty-one patients (82%) cured with conservative treatment. These patients continued a low fat diet for one month. The remaining 9 patients (8%) underwent surgical intervention at a median of 5.5 days after diagnosis (range 3 to 12 days). Postoperative chest tube drainage (ml/h) until first oral intake was significantly greater in the surgical intervention group than conservative group (37.4±15.7 ml/h vs. 24.7±9.7 ml/h; p=0.003). In multivariate analysis, postoperative chest tube drainage (ml/h) until first oral intake was significant predictor for the chylothorax patient required surgical intervention (p=0.012, Hazard Ratio 1.110, 95% Confidence Interval 1.024-1.205). Four patients (8%) had chest tube drainage exceeding 45 ml/h until first oral intake. Among them 3 patients (75%) required surgical intervention.Conclusion
Postoperative chest tube drainage (ml/h) was independent predictor for surgical intervention in postoperative chylothorax patients. If postoperative chest tube drainage exceed 45 ml/h until first oral intake, we should suspect postoperative chylothorax and consider early surgical intervention.Only Members that have purchased this event or have registered via an access code will be able to view this content.

P1.20-011 - Retrospective Study of Lung Cancer Screening. (ID 3372)
09:30 - 09:30 | Author(s): S. Uchida
- Abstract
Background
The lung cancer screening in Japan is only chest radiography now. But in 2011, the national lung screening trial research team was reported reduced lung-cancer mortality with low-dose computed tomographic screening. We studied lung cancer patients about a difference of a screening type, for example radiography and computed tomography.Methods
From January 2008 through May 2013, we performed the operation of 1344 lung cancer patients. In those patients, 1018 patients were proved the type of screening.Results
The number of patients by symptom, radiography and computed tomography are 146 (14%), 340 (33%) and 378 (37%), respectively. The rate of clinical stage I (789, 78%) are 72 (7%), 265 (26%), 338 (33%), respectively. The rate of pathological stage I (672, 66%) are 53 (5%), 212 (21%), 312 (31%), respectively. On the other hand, the rate of clinical III are 31 (3%), 25(2%), 14 (1%), respectively. The rate of pathological III are 47 (5%), 54 (5%), 31 (3%), respectively. The difference of between clinical stage I and screening type are 0.000, 0.813, and 0.000, respectively. The difference of between pathological stage I and screening are 0.000, 0.081, and 0.000, respectively.symptom radiography CT pt 146 340 378 age 64±1 64±0.7 67±0.5 cStage IA 50 199 296 IB 22 66 42 IIA 18 25 6 IIB 15 13 8 IIIA 25 21 12 IIIB 6 4 2 IV 7 3 1 pStage IA 35 155 259 IB 18 57 53 IIA 12 31 13 IIB 16 23 11 IIIA 41 50 30 IIIB 6 4 1 IV 12 7 4 Conclusion
In the group of symptom and radiography, there are a lot of advanced lung cancer patients, while in the group of computed tomography, we can detect a lot of early lung cancer patients. Computed tomography is better than the other screening about the detecting lung cancer. We should use a computed tomography in screening of lung cancer.
