Objective:The short term results of laparoscopic radical hysterectomy and pelvic lymph nodes dissection for early uterine malignancy were investigated.Methods:70 patients with eady malignant uterine tumor who underwent a laparoscopic radical hysterectomy and pelvic lymph nodes dissection(TLRH+LPL)were retrospectively reviewed.At the samt time,48 patients were recruited to be the control group who had laparotomy radical hysterectomy and pelvic lymph nodes dissection(ARH+APL).Intraoperative and postoperative situations and complications between these two groups were analyzed.Results:70 patients underwent laparoscopic operation,but two cases changed to laparotomy(transfer rate 2.9%).The mean operation time,blood loss,number of dissected pelvic lymph nodes and postoperative temperature recovery time of TLRH+LPL group was significantly different from ARH+APL group(P<0.01),while there were no difference between these two groups on bladder function recovery time and occurance of postoperative complications.Conclusions:TLRH+LPL has the same feasibility and safety with ARH+APL,less invasive to the tissue,thus offers a good option of microinvasive therapy for female malignant tumor.

Purpose：To determine the treatments and prognostic predictors of malignant melanoma of the head and neck. Methods：Surgical treatment and outcome was analyzed for 28 patients with malignant melanoma of the head and neck at department of the head and neck of our hospital (1984-1994). Results：23 patients underwent local excised as the first treatment, and local recurrence was demonstrated in 8 (34.8%). Margin of resection of primary melanoma was divided into narrow excision (≤2 cm) and wide excision (＞2 cm), and 5-year survival was 58% and 40%(P＜0.01). According to surgical methods, 5-year survival of WE, WE/END and WE/TLND were 80%, 80% and 39%. Conclusions：An excision with 2 cm margin is safe procedure for primary tumor of malignant melanoma of the head and neck. Neck dissection may not be practiced until neck lymph node is positive. Neck dissections differ from the positions of the primary tumors, and the flaps must be raised preferably superficial to the platysma.
