Objectives To analyze the efficacy and safety of different operation methods for patients with cesarean scar diverticulum. Methods The clinical data of patients with cesarean section scar diverticulum treated in West China Second University Hospital from July 2012 to December 2016 was collected and followed up. The data of the previous perioperative period data, recovery, the improvement of the symptoms and postoperative condition of incision healing were analyzed by SPSS 22.0 software. Results A total of 125 patients were included, in which 74 cases received hysteroscopy surgery for diverticulum electro section and electric coagulation (ESEC group), and 51 cases received other surgery focused on diverticulum dissection and sewing operations (DS group). Statistical analysis showed that, compared with DS group, bleeding, operation time, time of anal exsufflation and hospitalization duration after the operation of hysteroscopy in ESEC group were significantly reduced (P<0.001). In addition, the results showed that hysteroscopy group had optimal results in hemorrhage volume, operation time, anal exhaust time and hospitalization time indicators. However, the results of laparotomy group was not significant. Conclusions For the treatment of CSD, surgical treatment of this pathology by operative hysteroscopy may represent the best choice in symptomatic women because of its minimal invasiveness and beneficial therapeutic results. Hysteroscopy isthmoplasty appears to be the most popular treatment.
