Abstract:Objective To investigate the efficacy of combined hysteroscopy and laparoscopy for cesarean section scar diverticulum in women seeking fertility treatment.Methods A retrospective analysis was conducted on the medical records of 92 patients with cesarean section scar diverticulum admitted to Xuzhou Maternity and Child Healthcare Hospital from September 2021 to February 2024. Patients were divided into an observation group (50 cases) and a control group (42 cases) based on the treatment methods. Patients in the control group were treated with hysteroscopy alone, whereas those in the observation group received a combination of hysteroscopy and laparoscopy. The surgical indicators, postoperative thickness of the anterior lower uterine wall myometrium, postoperative cervical mucus inflammatory markers, treatment efficacy, and complications were compared between the two groups. Patients were followed for 1 year after surgery, and pregnancy rates were recorded.Results The observation group had longer operative duration, greater intraoperative blood loss, and longer postoperative vaginal bleeding duration and length of hospital stay than in the control group (P < 0.05). The change in anterior uterine wall myometrial thickness from pre- to post-surgery was greater in the observation group compared with the control group (P < 0.05). Postoperatively, levels of interleukin-2 (IL-2), tumor necrosis factor-α (TNF-α), and pH values decreased in both groups compared with preoperative values (P < 0.05). The overall treatment efficacy was higher in the observation group than in the control group (P < 0.05). There was no significant difference in the overall incidence of adverse reactions between the two groups (P > 0.05). The postoperative pregnancy rate was higher in the observation group than in the control group (P < 0.05), while no significant difference was observed in the miscarriage rate between the two groups (P > 0.05).Conclusion Combined hysteroscopy and laparoscopy for cesarean section scar diverticulum improves treatment efficacy and postoperative pregnancy rates, but may prolong the operative duration.
