Division of Thoracic Surgery, Veterans General Hospital-Kaohsiung. Kaohsiung, Taiwan, R.O.C. Video-Assisted thoracoscopy Surgery (VATS) is very useful in diagnosis of peripheral pulmonary nodules. During VATS it is impossible to do manual palpation. There has limitation to localize deep seated subpleural nodules. With CT-guided hook wiring or methylene blue injection, it shows some help but still has handycap. Recently we have used intraoperative sonography (OmniPlane, HP SONOS 500, 5 MHz) In VATS for 30 consecutive patients. These patients had peripheral pulmonary nodules which were not subpleural located. Chest CT scans of the patients were used as a control. In CT scan the distance from pleura to the posterior margin of the nodule was defined as Cp, to the anterior margin as Ca and nodule itself as Cm. In collapsed lung with sonography it was defined as Sp, Sa and Sm. We found that with careful measurement the Cm and Sm were always the same. With diffent condition of patient’s lung and gas block, the anterior margin of the nodule could not be well defined. The Sa and Sp had poor correlation with Ca and Cp. Sonography could detect any nodule with Cp less than 4 cm. We concluded that intraoperative sonography is feasible in VATS to localize pulmonary nodules. 642 Surgery For N1 Non-Small Cell Lung Cancer Min-Hsiung HUANG, Shyu-Lisng Hsu, Biingahiun Huang, Wen-Hu Hsu, LiangShun WANG, Kwsog-Yu CHIEN Division of Thoracic Surgery, Department of Surgery, Veterans General Hospital-Taipei, Taiwan,R.O.C.

Of the 61 patients received bilolxxlomy. they were 30. 7 and 24 in stage 1. II, and 111 respectively. The surgical morbidity was much higher in the bilobectomy group. The mean survial time of bilobectomy and lobeclomy were: 36 v.s 39 months in stage 1 group; 33 v.s 38 months in stage II group and 21 v.s 17 months in stage 111 group. All showed no significant difference. In conclusion: Radical lobectomy is still the best treatment for curable NSCLS, but bilobcctomy should not bc considered as a routine pmccdare for cancer of the right lower lung tield.

Video-Assisted thoracoscopy Surgery (VATS) is very useful in diagnosis of peripheral pulmonary nodules. During VATS it is impossible to do manual palpation. There has limitation to localize deep seated subpleural nodules. With CT-guided hook wiring or methylene blue injection, it shows some help but still has handycap.

In collapsed lung with sonography it was defined as Sp, Sa and Sm.

We found that with careful measurement the Cm and Sm were always the same. With diffent condition of patient’s lung and

gas block, the anterior margin of the nodule could not be well defined. The Sa and Sp had poor correlation with Ca and Cp. Sonography could detect any nodule with Cp less than 4 cm.

We concluded that intraoperative sonography is feasible in VATS to localize pulmonary nodules.

Lung cancer is the common cause of death in human being and

surgical intervention remains the treatment of choice for NSCLC. Cunenlly, radical lobectomy is the mOst frequently performed procedure. Under the concept of radical lymph nodes dissection and lymphatic sump of Honie, ‘lbilobectomy for cancer of either middle or lower lobe was generally accepted.

From June 1980 to June 1993, two hundred and thirty live consecutive patients with right middle or lower lobe lung cancer underwent

surgical treatment at Veterana Ckneral Hospital, Taipei R.O.C.. There were one hundred and thirty-live patienls underwent bilobectomy or lobectomy. The numbers of patients received lobectomy were as follow: 69 stage I; 13

stage II; 13 stage 111; and 5 stage IV. Of the 61 patients received

bilolxxlomy. they were 30. 7 and 24 in stage 1. II, and 111 respectively. The surgical morbidity was much higher in the bilobectomy group. The mean

survial time of bilobectomy and lobeclomy were: 36 v.s 39 months in stage 1

group; 33 v.s 38 months in stage II group and 21 v.s 17 months in stage 111 group. All showed no significant difference.

In conclusion: Radical lobectomy is still the best treatment for

curable NSCLS, but bilobcctomy should not bc considered as a routine
