Primary and repeated surgeries for ectopic pregnancies and distribution by patient age, surgeon age, and hospital levels: an 11-year nationwide population-based descriptive study in Taiwan.

STUDY OBJECTIVE: To describe the changing trend, repeat operation rate, and distribution of laparoscopy, as compared with laparotomy, in treating ectopic pregnancy, according to patient age, preoperative conditions, surgeon age, and hospital accreditation level, in Taiwan over 11-years. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Population-based nationwide insurance database. PATIENTS: Women who underwent either laparotomy or laparoscopy because of ectopic pregnancy. INTERVENTIONS: Women who had National Health Insurance (NHI) underwent various surgical procedures to treat ectopic pregnancy. Data for this study were obtained from the Inpatient Expenditures by Admissions files of the NHI Research Database, released by the NHI program in Taiwan between 1997 and 2007. MEASUREMENTS AND MAIN RESULTS: A total of 43 170 women with 44 928 operations were identified. Only the primary surgeries, via either laparotomy or laparoscopy, performed because of ectopic pregnancy were included for analysis. The annual number of procedures to treat ectopic pregnancies decreased in the later years of the 11-year study. Laparotomy decreased significantly, from 81.2% in 1997 to 26.2% in 2007, whereas laparoscopic procedures increased significantly, from 18.8% in 1997 to 73.8% in 2007, as evidenced at log-linear regression analysis (p < .001). The rate of repeat operations because of persistent ectopic pregnancy was higher in the laparoscopy group than in the laparotomy group (0.38% vs 0.14 %; p < .001). Patients were more likely to undergo the same type of operation for the repeated surgery (i.e., laparotomy to laparotomy in 73.1% or laparoscopy to laparoscopy in 80.2%; p = 0.43). Use of laparoscopy (58.1%) and laparotomy (41.9%) differed according to patient age, preoperative comorbidities, surgeon age, and hospital accreditation level and ownership type. With older patients, those with preoperative anemia or shock, and elder surgeons, there was a greater chance that laparotomy would be performed. The probability of undergoing laparotomy was greater in patients in regional hospitals, local hospitals, and office-based clinics compared with those in medical centers. CONCLUSIONS: There has been considerable change in the type of surgical approach used to treat ectopic pregnancy in Taiwan over the past 11 years. Laparoscopy is preferred to laparotomy, and has become the standard surgical approach to treating ectopic pregnancies in Taiwan. However, laparoscopy is associated with a higher rate of repeat operations. The laparoscopic approach signifies a profound change in treating ectopic pregnancies among patients, surgeons, and hospital types.

Quantified short-term outcome of uterine artery embolization with gelatin sponge particles and lipiodol for symptomatic myoma.

OBJECTIVE: To investigate and quantify clinical outcomes and spectral Doppler analyses of uterine arteries in patients with myoma undergoing uterine artery embolization (UAE) with gelatin sponge particles and lipiodol. DESIGN: Prospective observational study. SETTING: Tertiary medical center. PATIENT(S): Forty premenopausal women with symptomatic myoma. INTERVENTION(S): Uterine artery embolization with gelatin sponge particles and lipiodol. MAIN OUTCOMES MEASURE(S): Hemoglobin, hematocrit, CA-125, pictorial blood loss assessment, visual analogue pain scale, questionnaire for symptoms, tumor volume, and spectral Doppler analyses of uterine arteries. RESULT(S): The mean follow-up period was 8.1 months (range, 6-12). Menstrual flow improved in 29 of 35 patients (83%) and decreased significantly by 78.4%. Menstrual pain improved in 27 of 35 patients (77%) and decreased significantly by 70%. Hematocrit and CA-125 improved significantly. The mean percentage reductions of uterine and myomal volumes were 40.2% and 54.9%, respectively. The mean peak systolic velocity of the uterine arteries decreased by 52%. The major complication rate was 2.56%. There was no correlation between tumor volume reduction and clinical outcome. CONCLUSION(S): Uterine artery embolization with gelatin sponge particles and lipiodol had satisfactory short-term outcomes, comparable to those associated with polyvinyl alcohol particles. Quantified and semiquantified measurements provided objective assessment of clinical outcomes. Serum CA-125 might play a role in clinical follow-up. Reduction of tumor volume is not predictive of UAE efficacy.
