Ovarian malignancy accounts for 1/4 of all malignant tumors of the female reproductive tract, but it has the 1st highest mortality rate. Comprehensive staging surgery at early stage and tumor cell reduction at advanced stage have become the first choice for the treatment of ovarian malignancies. For patients whose initial surgical staging is not comprehensive, they should undergo comprehensive staging surgery again before the start of chemotherapy to achieve comprehensive staging, called restaging surgery. Re-staging surgery, on the one hand, has the potential to spare those patients with truly early stage from unnecessary chemotherapy; on the other hand, it also has the potential to detect the presence of advanced stage patients, to achieve complete tumor reduction and to avoid under-treatment. There are few reports in the national and international literature regarding the value of laparoscopic restaging surgery. OBJECTIVE: To investigate the clinical application value of laparoscopy in re-staging surgery for early-stage ovarian malignancies. METHODS: The clinical data of 16 cases of laparoscopic re-staging surgery for early ovarian malignancy were retrospectively analyzed. 13 cases of stage Ia and 3 cases of stage Ic were diagnosed after initial surgery, and the procedures included laparoscopic total hysterectomy, preserved adnexal resection, high pelvic funnel ligament ligation, major omentectomy, pelvic and para-aortic lymph node dissection, and/or appendectomy. RESULTS: All 16 patients successfully completed re-staging under laparoscopy without intraoperative and postoperative complications, with intraoperative bleeding ( 86. 5 ± 30. 6) ml, operative time ( 160. 6 ± 36. 9) min, number of pelvic lymph nodes removed (19.5 ± 4. 6), number of para-aortic lymph nodes removed (6.5 ± 2. 6), postoperative staging from stage Ia in 1 case One case was staged from stage Ia to Ib, two cases were staged from Ia to Ic, and one case was staged from Ic to IIIc. For those staged above stage Ib or by high-risk factors, 3-6 courses of chemotherapy with conventional PT regimen were administered, and there was no recurrence or perforation metastasis during follow-up. CONCLUSION: Laparoscopic re-staging surgery for early ovarian malignancy is safe and feasible, which is conducive to accurately determining the stage and guiding postoperative adjuvant chemotherapy, and is in line with the current trend of minimally invasive and radical tumor treatment.
