Study Objective: To explore the effectiveness of a modified suspension method combined with Gasless single-port laparoscopy (MS-GSPL) for the treatment of benign ovarian tumors. The aim of this approach is to provide a convenient, economical,and minimally invasive method that is suitable for widespread use, even in middle- and low-income countries or primary hospitals. Design: A retrospective comparative study. Setting: University teaching hospital. Patients: Thirty-six cases were treated with MS-GSPL, and thirty-six cases were treated with single-port laparoscopy (SPL). Interventions: Use a modified suspension method combined with Gasless single-port laparoscopy for the treatment of benign ovarian tumors. Measurements and Main Results: There are no significant differences in age, body mass index,previous pelvic surgery, tumor diameter ,and tumor pathologic outcomes between MS-GSPL group and SPL group.The median operation times were 50(Q1~Q3 , 44~62.25)min in the MS-GSPL group and 60.5(Q1~Q3 , 57.25~78)min in the SPL group with a significant difference. The median estimated blood loss were 40 (Q1~Q3 , 30~50)ml in the MS-GSPL group and 50(Q1~Q3 , 30~60) ml in the SPL group with no significant difference. Compared with SPL group, patients in MS-GSPL group had earlier postoperative exhaust times, shorter hospital stays and lower costs, and all these differences were statistically significant(P<0.05). There was a strong positive correlation between operation time and BMI in the MS-GSPL groups. Conclusion: The patients receiving MS-GSPL treatment have quick postoperative recoveries. MS-GSPL is a novel, safe and economical surgical method that is suitable for extensive clinical development in middle- and low-income countries or primary hospitals.
