This study identified prior surgery, bilateral cysts, and multiple cysts as recurrence risk factors for fertile patients, while older age, multiple cysts, and controlled ovarian hyperstimulation predicted recurrence in infertile patients undergoing laparoscopic endometrioma cystectomy.

This prospective observational study followed 153 patients undergoing laparoscopic cystectomy for ovarian endometrioma at Toho University Medical Center, Sakura Hospital for 2 to 5 years, comparing those with and without recurrence. Endometrioma recurred in 22.9% of patients, and in those with fertility intact, prior surgery, bilateral cysts, and having multiple cysts were associated with recurrence. In infertile patients, older age, multiple cysts, and controlled ovarian hyperstimulation were identified as risk factors, with the authors noting that complete excision of the endometrioma may influence recurrence risk. This paper is centrally about endometriosis — it specifically evaluates risk factors for recurrent ovarian endometrioma after laparoscopic cystectomy.

Abstract

Objective: To identify factors associated with endometrioma recurrence after laparoscopic cystectomy.Design: Prospective observational study.Setting: Toho University Medical Center, Sakura HospitalPatient: Patients (N=153) undergoing laparoscopic cystectomy for ovarian endometrioma, followed postoperatively for two to five years.Intervention: Subjects were grouped by recurrent and nonrecurrent status. Main outcome: Evaluated parameters included endometrioma recurrence, patient age, prior surgery, previous medical treatment, cyst diameter, endometriosis stage and score, percentage of bilateral cysts, presence of multiple cysts, controlled ovarian hyperstimulation, and postoperative pregnancy.Result: Endometrioma recurred postoperatively at a rate of 22.9%. With fertility intact, prior surgery, bilateral cysts, and the presence of multiple cysts were associated with endometrioma recurrence. For infertile patients, older age, the presence of multiple cysts, and controlled ovarian hyperstimulation were identified as risk factors.Conclusion: The ability to effect complete surgical excision of endometrioma may significantly impact the risk of recurrence.

Abstract

Objective: To identify factors associated with endometrioma recurrence after laparoscopic cystectomy. Design: Prospective observational study. Setting: Toho University Medical Center, Sakura Hospital Patient: Patients (N=153) undergoing laparoscopic cystectomy for ovarian endometrioma, followed postoperatively for two to five years. Intervention: Subjects were grouped by recurrent and nonrecurrent status. Main outcome: Evaluated parameters included endometrioma recurrence, patient age, prior surgery, previous medical treatment, cyst diameter, endometriosis stage and score, percentage of bilateral cysts, presence of multiple cysts, controlled ovarian hyperstimulation, and postoperative pregnancy.

Result

Endometrioma recurred postoperatively at a rate of 22.9%. With fertility intact, prior surgery, bilateral cysts, and the presence of multiple cysts were associated with endometrioma recurrence. For infertile patients, older age, the presence of multiple cysts, and controlled ovarian hyperstimulation were identified as risk factors.

Conclusion

The ability to effect complete surgical excision of endometrioma may significantly impact the risk of recurrence. Design: Prospective observational study.
