Aim To compare the effect of pituitrin local injection (PIT) and uterine artery embolization (UAE) as pretreatment before surgery during the management of cesarean scar pregnancy (CSP). Methods Forty‐nine CSP patients diagnosed in our department of Suzhou Ninth People's Hospital from October 2017 to October 2019. All patients underwent hysteroscopy and negative pressure aspiration (for type I CSP) or laparoscopic wedge‐resection (for type II and III CSP) following one of the preoperative treatments: PIT group (n = 26) and UAE group (n = 23). The baseline clinical data, intraoperative blood loss, blood transfusion rate, postoperative hospital stay, hospitalization expenses, postoperative pain, postoperative fever, postoperative serum β‐human chorionic gonadotropin (β‐hCG) level, and pregnancy outcome were reviewed and analyzed. Results There was no significant difference (p ≥ 0.05) between two groups in baseline characteristics including age, gravidity, previous cesarean section times, interval since last cesarean delivery, menolipsis time, maximum diameter of gestational sac or mass under ultrasound, fetal cardiac activity and preoperative β‐hCG level. There was no significant difference in blood loss, transfusion rate, and postoperative β‐hCG reduction percentage (p ≥ 0.05) either. The postoperative hospital stay, hospitalization expenses, postoperative pain, and postoperative fever rate in PIT group were significantly lower than those in UAE group (p < 0.05). Moreover, β‐hCG level of all patients turned negative 1 month after surgery successfully. Conclusions PIT pretreatment seems to be a same effective, more economical, and with fewer side effects pretreatment method compared to traditional UAE pretreatment in the management of CSP.

Background: There is currently no agreement on the optimal management of caesarean scar pregnancy. Caesarean scar pregnancy is currently categorised into two subtypes according to the site of implantation. This may consequently result in the difference in treatment options. However, the comparison of the success rate of each treatment option according to the subtypes has not been fully investigated.Methods: 71 patients who were treated by uterine curettage (D and C), or uterine artery embolization with curettage (UAE) or hysteroscopy in conjunction with laparoscopy between January 2016 and March 2020 were included. Data on maternal age, gestational sac age, the sac diameter, the interval between two pregnancies, the number of previous caesarean sections, amount of bleeding and β-hCG levels were collected and analysed dependent on the subtypes.Results: There was no difference in the clinical parameters of the cases who received different options of treatment, as well as no difference in the clinical parameters between type 1 and type 2 caesarean scar pregnancy. The primary success rate for type 1 caesarean scar pregnancy by D and C, or UAE, or hysteroscopy in conjunction with laparoscopy was 95, or 100 or 100%, respectively. The primary success rate for type 2 caesarean scar pregnancy by D and C, or UAE, or hysteroscopy in conjunction with laparoscopy was 27, or 67, or 95% respectively.Conclusion: Our data demonstrates that hysteroscopy in conjunction with laparoscopy for type 2 caesarean scar pregnancy was the most successful compared to other options, but for type 1 caesarean scar pregnancy, D and C could be the cost-effective option.

Rationale: Ectopic twin gestation involving a complete hydatidiform mole (CHM) and coexisting embryo is an exceedingly rare occurrence. Patient concerns: In this report, we present the case of a 22-year-old female (gravida2, para 1) who was in her 8th week of gestation and presented with abdominal pain. Due to the detection of active bleeding and a ruptured right fallopian tube, the patient underwent a salpingectomy on the right side. Diagnosis: The patient was diagnosed with an ectopic twin gestation involving a CHM and coexisting embryo. Interventions: The patient was treated with right-side salpingectomy. Outcomes: The operation was successful and her recuperation was satisfactory. Lessons: In the management of ectopic pregnancy involving CHM, it is crucial to enhance the accuracy of preoperative diagnosis. Additionally, histopathological examination of the salpingectomy specimen and conceptus is definitely essential for accurate diagnosis and appropriate follow-up management of tubal pregnancies.
