Standard of practice on laparoscopic gastric cancer surgery in Korea and Japan: experts' survey.

INTRODUCTION

As the laparoscopic approach has become a popular gastric cancer treatment in Korea and Japan, the need for sharing current practices of surgeons who are experienced in laparoscopic gastric cancer surgery has increased.

METHODS

We sent a questionnaire on laparoscopic instruments, image documentation, preoperative evaluation, surgical indication, operative methods, and postoperative management to laparoscopic experts in Korea and Japan, and 24 (14 from Korea and 10 from Japan) responded.

RESULTS

Endoscopic ultrasound and preoperative endoscopy-guided clipping are routinely employed, respectively, by 14 (58%) and 20 (83%) of the surgeons. Surgeons perform laparoscopy-assisted distal gastrectomy (LADG) based on varying indications. Five surgeons (21%) performed LADG only for cases of stage T1 cancer, 15 (63%) performed LADG on patients with less than T2 lesions, and 4 (17%) performed LADG on patients with less than T3 lesions. With regard to postoperative anastomosis, 18 surgeons (75%) preferred extracorporeal anastomosis and 6 (25%) preferred intracorporeal anastomosis. The mean postoperative hospital stay was 6.5 days in Korea and 10.1 days in Japan (P < 0.001).

CONCLUSION

This survey can help to inform the current practice of laparoscopic gastric cancer surgery in Korea and Japan, where laparoscopic surgery is frequently performed.
