Abstract: Objective To study the feasibility of transumbilical single-site laparoscopic surgery for tumors in women. Methods Laparoscopic single-site surgery was performed in 2 patients in January 2010.One of them underwent laparoscopic singlesite decollement of ovarian teratoma,the other underwent laparoscopic single-site total hysterectomy for hysteromyoma.The abdominal cavity was exposed through an incision with three 5mm-long puncture outfits. Results The operation was successful with no complications such as bleeding.No significant scar was observed on the surface of umbilicus after operation. Conclusion Transumbilical single-site laparoscopic surgery is safe and feasible for tumors in women with a more obvious cosmetic and minimally invasive effect than routine laparoscopy.
