[The clinical efficacy of laparoscopic cornuotomy on interstitial tubal pregnancy which diameter was shorter than 3 cm].

Objective: To investigate the clinical efficacy of Laparoscopic cornuotomy on Interstitial Tubal Pregnancy (IP) which diameter was shorter than 3 cm. Methods: The women who had IP under 3 cm diameter were selected from January, 2016 to December, 2018 at the Department of Gynecology, JiaXing Maternity and Child Health care Hospital. A total of 32 IP patients were divided into two groups. They were all treated with laparoscopic surgery. 17 patients were in study group, conducted by a cornuotomy and suturing the cornual.15 patients were in control group, conducted by a cornual resection and suturing the cornual. Patients' genenral conditions were not significantly different(all P values>0.05). The peri-surgical data and the related clinical data were compared in the two groups. Results: All the 32 patients were successfully treated by laparoscopic surgery. The mean operating time was significantly shorter for cornuotomy than for cornual resection[ (33±6) min vs (53±9) min, P<0.05].Changes in blood loss[(45±5) ml vs (50±7) ml]、the total hospital stays[ (4.4±1.4) d vs (4.6±1.4) d] and the recovery time of HCG[(16±5) d vs (15±5) d] were not significantly different between the two groups (all P values>0.05) . There were no persistent ectopic pregnancy and uterine rupture happened in two groups. Compared with the control group,the interval time to pregnancy was shorter[ (8±3) m vs (16±4) m, P<0.05] and the number of full-term pregnancy cases were more (9 vs 3, P<0.05). Conclusion: The Laparoscopic cornuotomy was feasible and safe on interstitial tubal pregnancy which diameter was shorter than 3cm. It deserved popularization in the clinical work and regarded as one of selection operative treatment on interstitial heterotopic pregnancy.
