Abstract:

Objective  To explore the risk factors of tubal ruptures of patients with eccyesis. Methods  Clinical data of 209 patients with tubal pregnancy who were admitted by Renji Hospital South Campus, Shanghai Jiao Tong University School of Medicine from 2013 to 2014 were collected and retrospectively analyzed. Among them, 58 cases were diagnosed with ruptured tubal pregnancy (rupture group) and 151 cases were diagnosed with un-ruptured tubal pregnancy (un-rupture group). Diagnoses were made depending on the results of surgical and pathological examinations. Risk factors of ruptured fallopian tubal pregnancy were statistically analyzed. Results  The differences of reproductive history, abdominal pain, presence of tear abdominal pain, vaginal bleeding days, hemoglobin level before operation, the biggest diameter line of the lump under B ultrasound, and pelvic cavity effusion between two groups were statistically significant (P<0.05). According to multiple factors logistic stepwise regression analysis, age, history of abortion, contraceptive ring, tear abdominal pain, pelvic cavity effusion, and the biggest diameter line of the lump under B ultrasound were introduced as variables of regression equation. Conclusion  Age, contraceptive ring, tear abdominal pain, the biggest diameter line of the lump under B ultrasound, and pelvic cavity effusion are risk factors of ruptured tubal pregnancy, while abortion history is the protection factor. Above factors should be considered for clinical decisions to avoid ruptured tubal pregnancy and endangering patients' lives.
