Purpose: This study aimed to investigate the clinical efficacy of temporary ligation of the bilateral uterine arteries during laparoscopy combined with hysteroscopy in the treatment of caesarean scar pregnancy (CSP). Patients and Methods: This study was a retrospective analysis of 83 patients who had initially undergone laparoscopy combined with hysteroscopy for CSP between 2012 and 2018 at Xiamen Women and Children's Hospital. Patients were assigned to the ligation group or the no ligation group according to whether they underwent temporary ligation of the bilateral uterine arteries. Factors extracted from the database included general preoperative information, surgical indicators (intraoperative blood loss, operation time, and blood transfusion), postoperative recovery indicators (β-hCG on day 3 after surgery, time to β-hCG normalization), and postoperative complications (decrease in menstrual bleeding, alteration in the menstrual cycle) and were compared between the two groups. Results: The intraoperative blood loss of patients in the ligation group was significantly less than that of patients in the no ligation group (P=0.027), especially in patients with higher serum β-hCG level (P=0.030). No significant differences in the operation time, blood transfusion, decline ratio of hCG on day 3 after surgery, reduction in haemoglobin and haematocrit value, decrease in menstrual bleeding, or alteration in the menstrual cycle were observed between the two groups (P> 0.05). Conclusion: For CSP patients, temporary ligation of the bilateral uterine arteries during laparoscopy combined with hysteroscopy achieved better clinical outcomes than laparoscopy combined with hysteroscopy without ligation with respect to intraoperative blood loss. This approach offers effective and safe surgical management for CSP in clinical practice. [ABSTRACT FROM AUTHOR]
