Gasless Laparoscopic Surgery for Benign Ovarian Tumors during Pregnancy:a Report of 45 Cases / 中国微创外科杂志

ABSTRACT

Objective To investigate the feasibility, safety and effect of gasless laparoscopic surgery in the treatment of benign ovarian tumors during pregnancy. Methods Clinical data of 45 pregnant women with benign ovary tumors undergoing gasless laparoscopic surgery from January 2006 to June 2013 were studied retrospectively.Most of the cases were given oophorocystectomy. Adnexectomy was performed for the large sized lesions, lacking of or remaining few normal ovarian tissue, or ovarian cyst torsion. Results All the 45 cases were successfully treated by gasless laparoscopic surgery.No perioperative and postoperative complications were observed.There were 42 cases receiving ovarian tumor resection while 3 cases receiving simple salpingo-oophorectomy.The mean operation time was (40.7 ±14.9) min (25-90 min), the mean blood loss was (27.3 ±16.6) ml (10 -80 ml), and the mean hospitalization time was (4.5 ±1.3) days (3-8 days).At pre-, peri-, and post-operative time, the blood pH value, blood pressure carbon dioxide (PaCO2), and blood oxygen partial pressure (PaO2) showed no statistical difference (F=0.00,P=0.999;F=2.21, P=0.114;F=0.60,P=0.555), and blood bicarbonate (HCO3-) and blood oxygen saturation (SpO2) showed statistical difference but no clinical significance (F=14.96,P=0.000;F=9.45,P=0.999), all of which were in the normal range.The fetal heart rates were all in the normal range.Pathological diagnoses were ovarian mature cystic teratoma in 25 cases (55.6%), serous cystadenoma in 6 cases (13.3%), mucinous cystadenoma in 4 cases (8.9%), mesosalpinx cyst in 3 cases (6.7%), endometrial cyst in 2 cases (4.4%), and luteal cyst in 5 cases (11.1%).No spontaneous abortion was found in post-operational follow-up.Term delivery was obtained in 43 cases, with normal fetal weight and the Apgar scores.Two cases gave up the pregnancy in the postoperative period. Conclusion Gasless laparoscopic surgery for benign ovarian tumors during pregnancy is safe and feasible.
