Objective To summarize the application of Ivor -Lewis in the treatment of esophageal cancer and to explore the value of clinical application.Methods The clinical data of 1 92 esophageal cancer patients who received Ivor -Lewis treatment were retrospectively analyzed,and followed the survival situation.Results In 192 cases,the surgery cut edges were negative.No postoperative death was observed.Anastomosis fistula occurred in 37 cases.1 year survival rate was 86.4%(1 40 /1 62),and 3 year survival rate was 52.4%(22 /42).Conclusion The application of Ivor -Lewis in the treatment of esophageal cancer can not only meet the principles of surgical treatment for tumors, but also can reduce the operation difficulty.At the same time,it is benefit to resect the lymph nodes located in the chest and abdomen,and also improve the effect of surgical treatment.

Objective To explore the therapeutic effect of several treatments on spontaneous pneumothorax. Methods A total of 157 patients with spontaneous pneumothorax were analyzed retrospectively from Dec 2013 to Dec 2016. Among them, 51 cases were in conservative treatment group and 106 cases were in operative group; 58 cases were in video-assisted thoracoscopic surgery (VATS) bullectomy only, 48 cases were in tubular Neoveil materials combined with an automatic stapler in the bullectomy, respectively. To observe the clinical data and curative effect of the related treatment, the postoperative follow-up period ranged from 6 to 42 months. Results The rate of complications was no significant difference between the conservative and operative group. The chest tube removal time 7.05土1. 85(4～14) days vs. 3.49 ±1.19(2～7)days(P=0.000)and the rate of recurrence(9 cases: 17％ vs.5 cases:4.7％ P = 0.021) have significant differences. The chest tube removal time 3.26 ± 1.16(2～7) days vs.3.79±1.16 (2～7) days(P = 0.085) and the postoperative complications (4 cases and 2 cases, P = 0.286) have no significant difference between VATS bullectomy group and Tuber Neoveil bullectomy group. The postoperative hospital stay time was shorter than that in VATS bullectomy 5.97 ±1.9(4～16)days vs.6.71 ±1.91 (5～15)days(P=0.022). However the postoperative recurrence rate was significantly lower than that in Neoveil group(0 case)(P=0.041). Conclusion These results suggest that the use of Tuber Neoveil may be effective for the prevention of postoperative recurrence of spontaneous pneumothorax.
