Abstract

Objectives: This study aimed to evaluate hysteroscopic-guided suction evacuation for the treatment of cesarean scar pregnancy (CSP).

Materials and methods: This was a retrospective analysis of CSP over 2 years. This study was conducted at KK Women's and Children's Hospital (KKH), Singapore, thirty-seven patients with a CSP. Hysteroscopic-guided suction evacuation to treat CSP used alone or in combination with laparoscopy depending on residual myometrial thickness (RMT) and future fertility requirements.

Results: The majority of women (29) were diagnosed under 9-week gestation. Just over a third (13) had an RMT of more than 3 mm. Women with an RMT <3 mm had added laparoscopy. In total, 22 women had hysteroscopic-guided suction evacuation with 9 having it performed under laparoscopic guidance because the RMT was under 3 mm. The remaining patients underwent either laparoscopic repair (5 cases) or vaginal repair (1 case) done under laparoscopic guidance.

Conclusion: Hysteroscopic-guided suction evacuation of CSP has the potential to become part of the routine management for uncomplicated cases of CSP in women with an RMT of greater than 3 mm who do not wish for future pregnancy. Its use, in combination with other minimally invasive techniques, can be extended to more complex cases where the RMT is <3 mm and future fertility is desired.
