RESUMEN
Objective To develop a more effective method to treat proximal tubal obstruction. Methods In a total of 89 cases, there were 113 oviduct lesions diagnosed by hysterosalpingogram (HSG) and then by laparoscopy as proximal tubal obstructions. Intubations and recanalizations were performed by means of laparoscopy combined with hysteroscopy. Results Out of the 113 oviduct lesions in 89 cases, 73 (64.6%) were recanalized. In follow-up of 20 days～58 months, there were 20 cases of successful pregnancies and labours, 2 inevitable abortions and 1 ectopic pregnancy, with the rate of pregnancy 25.8% (23 of 89). Conclusions It is an effective approach to treat proximal tubal obstruction by using laparoscopy combined with hysteroscopy. It can also be used to identify the true proximal tubal obstruction from the false one.
