ABSTRACT

Objective To study the application of ultracision harmonic scalpel in laparoscopic radical gastrectomy.Methods Ten patients with gastric cancer were given laparoscopic-assisted radical gastrectomy by using ultracision harmonic scalpel.Results All operations were successfully performed with ultracision harmonic scalpel,and none of which converted into open surgery.The operation time was 300-492 min,mean(385?64) min.The blood loss was 100-500 ml,mean(401?70) ml.The number of harvested lymph nodes was 21-43,mean 31?6.The time for gastrointestinal function recovery was 3-6 d,mean(4.2?1.0) d.The time of patients' taking out-of-bed activity was 3-7 d,mean(4.5?1.3) d.The time of taking liquid food was 4-6 d,mean(5.0?0.9) d.No case had relapse or metastasis after 4-20 months(mean 12.6 months) of follow-up.Conclusions Laparoscopic radical gastrectomy by using ultracision harmonic scalpel is safe and feasible.Ultracision harmonic scalpel has the advantage of minimal invasion,less bleeding and shorter operation time,which is a very important equipment and useful for laparoscopic gastrointestinal surgery.

ABSTRACT

Objective To investigate the correlation between postoperative intraabdominal adhesions and tumor growth and metastasis and to evaluate the effect of PDLLA. Methods Sixty male Wistar rats were divided into tumor transplantation group ( A group) and non-tumor-transplantation group (B group). Both groups were further subdivided into intraabdominal adhesion model subgroup, PDLLA intervention subgroup and false operation subgroup respectively. Postoperative intraabdominal adhesions and tumor growth and metastasis were semiquantitively scored 4 weeks after the operation. Results The scores of intraabdominal adhesion and the tumor growth and metastasis in all subgroups of tumor transplantation group were higher than that of non-tumor-transplantation group ( P
