To investigate the effects of balloon-expandable stent on prevention against readhesion in patients with moderate-severe intrauterine adhesion after trans-cervical resection of adhesion.

Fifty-two patients with moderate-severe intrauterine adhesion who were treated in Houjie Hospital of Dongguan Affiliated to Guangdong Medical University from August 2017 to July 2018 were selected as research objects. And they were divided into control group and experimental group according to random number table method, with 26 cases in each group. Patients in control group were only implanted with loop after trans-cervical resection of adhesion. For patients after trans-cervical resection of adhesion in experimental group, balloon-expandable stent was implanted in cervix for 7 days firstly, and then the round loop was placed in their body after pulling stent out. The loops were took out at the third day after menstruation. The blood volume 48 hours after treatment, recovery of cavitas uteri, volume and duration of menstruation, readhesion rate and incidence of complications were observed and analyzed in the two groups.

Readhesion rate and incidence of complications in experimental group(0, 3.85%) were significantly lower than those in contrl group (23.08%, 30.77%), P<0.05. The blood volume 48 hours after treatment, volume and duration of menstruation of experimental group was (46.28±3.54)ml, (26.21±1.06)ml and (6.58±0.56)d, which were better than (79.25±5.64)ml, (20.31±1.56)ml and (4.02±1.36)d of control group (P<0.05).

For patients with moderate-severe intrauterine adhesion, implanting balloon-expandable stent after trans-cervical resection of adhesion could reduce readhesion rate with less blood volume 48 hours after operation and higher safety. It is worth clinical promotion and application.
