Objective To evaluate the effect of endoscopic surgery combined with intraoperative color Doppler ultrasound on removing the injected breast augmentation agents and share our experiences. Methods Sixteen female who accepted the bilateral removal of injected breast augmentation agents through endoscopic surgery combined with intraoperative color Doppler ultrasound between 2008 and 2010 were enrolled in this study. The results, techniques, and advantages of management were analyzed retrospectively. Results One incision was made in 18 breasts, 2 in 4 breasts, 3 in 10 breasts. The length of incision was 0.5 to 1 cm. The mean operative time was 128.70 min per person. The average amount of bleeding was 52.67 ml per person. Complications such as postoperative bleeding, infection, poor drainage, or breast augmentation agents remain did not happened in all cases. No case was turned into normal operation. Female who accepted this operation were all satisfied with the appearance of incisions. During 1-3 months follow up, neither clinically palpable mass nor sensory disturbance in nipple or areola of breast was observed. Color Doppler ultrasound or magnetic resonance showed 16 cases had been cleared free of breast augmentation agents. Conclusion With the advantages of beauty, safe, minimal invasion, and partial resection of lesions at the same time, endoscopic surgery combined with intraoperative color Doppler ultrasound was an effective approach in the removal of injected breast augmentation agents.
Objective To evaluate the clinical effectiveness of laparoscopic and open appendectomy. Methods Literatures relating to randomized controlled trials in English and Chinese on the comparison of clinical effectiveness after laparoscopic and open appendectomy in appendicitis from PubMed，Wiley Online Library，Medline，Embase，Cochrane，CNKI，VIP，CBM databases were extracted，and methodological quality was evaluated by two reviewers independently with designed extraction form. The Cochrane Collaboration’s RevMan 4.2.2 software was used for data analysis. The wound infection，hospitalization time，operation time，hospitalization expenses，and peritoneal abscess were compared between laparoscopic and open appendectomy. Results Eight published reports of eligible studies were extracted. Compared with the open appendectomy， laparoscopic appendectomy had significant differences in lower wound infection rate 〔OR=0.19，95%CI （0.09，0.38），P＜0.000 01〕， longer operation time 〔WMD=3.66，95%CI （0.50，6.82），P=0.02〕，and more hospitalization expenses〔WMD=503.96，95%CI （337.23，670.70），P＜0.000 01〕.But there were no significant differences in hospitalization time〔WMD=-0.11，95%CI （-3.64，3.43），P=0.95〕 and incidence rate of peritoneal abscess 〔OR=1.40，95%CI （0.23，8.64），P=0.71〕 between laparoscopic and open appendectomy. Conclusions The wound infection rate is lower，but the operation time is longer，the hospitalization expenses is more in laparoscopic appendectomy as compared with open appendectomy. There are no statistically significant differences of hospitalization time and incidence rate of abdominal abscess between laparoscopic and open appendectomy.
