Comparative effectiveness of laparoscopic versus hysteroscopic approach in patients with previous cesarean scar defect: a retrospective cohort study

Abstract

BACKGROUND: The aim of this study was to evaluate the clinical effectiveness and obstetric outcomes of laparoscopic and hysteroscopic surgery in patients with previous cesarean scar defect (PCSD). METHODS: A retrospective cohort analysis was performed on women who underwent laparoscopic or hysteroscopic surgery for PCSD from 2016 to 2019 at the Third Xiangya Hospital of Central South University. Among these participants, 13 underwent laparoscopic surgery and 33 received hysteroscopic surgery. RESULTS: Significant differences were displayed in the operative times (156.9±42.3 vs. 40.7±38.9 min, P<0.05), intra-operative blood loss (80.0±61.0 vs. 17.9±51.2 mL, P<0.05), hospital stay (7.1±1.6 vs. 4.1±2.1 days, P<0.05), postoperative hospital stay (4.3±0.8 vs. 1.5±1.1 days, P<0.05), and hospitalization expenses (22,240.3±249.9 vs. 9,547.1±4,747.2 yuan, P<0.05) between the laparoscopic surgery and hysteroscopic group. No significant difference was observed in the incidence of clinical efficacy between the laparoscopic and hysteroscopic surgery group. A total of 2 of the 4 patients in the laparoscopic surgery group, and 9 of 11 patients in the hysteroscopic surgery group delivered successfully. All 2 participants in the laparoscopic surgery group and 2 participants in the hysteroscopic surgery group were diagnosed with placenta previa. No uterine rupture was reported in our study. CONCLUSIONS: Both laparoscopic and hysteroscopic surgery are safe and effective treatments for PCSD patients, and hysteroscopic surgery is more efficient for PCSD patients.
