Abstract
Objective: The surgical approach, hemostatic approach, histologic findings, and cyst size and location may have a role in reducing the ovarian reserve. The aim of this study was to investigate the impact of single-port laparoscopic cystectomy (SLC) and conventional laparoscopic cystectomy (CLC) on the ovarian reserve based on serum anti-Mullerian hormone (AMH) concentrations. Material and methods: This non-randomized concurrent control trial enrolled 79 female patients aged 18-45 years with benign ovarian cysts, including 47 patients in the SLC group and 32 patients in the CLC group. Outcome measures, including hospital stay, operative time, blood loss, analgesic use, body temperature, hospitalization cost, and serum AMH concentration, were evaluated preoperatively, two to three days postoperatively, and four to six weeks postoperatively. Results: The reduction in the AMH concentration after cystectomy was significantly different preoperatively, two to three days postoperatively (p < .001), and four weeks postoperatively (p < .001) regardless of the surgical approach (SLC or CLC) [F (1.00,31.00) = 0.026, p = .873]. Moreover, the hemostatic approach and histologic findings yielded significant differences in the serum AMH concentration regardless of the surgical approach (p < .05). The serum AMH concentration was higher in unilateral cysts (2.70 ± 1.80 ng/mL) than in bilateral cysts (1.73 ± 1.11 ng/mL) postoperatively (p < .05). In the SLC group, the serum AMH concentration in the patients with ovarian endometriomas (1.58 ± 1.39 ng/mL) was significantly lower than that in the patients with other cysts (3.22 ± 1.68 ng/mL) postoperatively (p < .05). Conclusion: The serum AMH concentration decreased over time postoperatively but did not significantly differ between SLC and CLC.
