Preoperative treatment with Lamicel tent for first trimester therapeutic abortion was evaluated in an open randomized trial and compared with no treatment. Measured by the lowest Hegar moved through the internal os without resistance, the Lamicel group had significantly higher cervical dilatation than the control group (8.2 mm vs. 5.8 mm; P less than 0.001). One perforation was observed in the Lamicel (n = 270) group compared to six in the control group (n = 359) (not significant). There was no difference between the groups in the frequency of readmissions to the hospital. During one year of clinical experience with pretreatment of elective abortion with Lamicel per- and postoperative complication rates were not reduced.
在一项开放性随机试验中，对用于孕早期治疗性流产的Lamicel扩张器进行术前治疗，并与未治疗组进行比较。以通过宫颈内口时能无阻力通过的最小黑加耳氏扩张器测量，Lamicel组的宫颈扩张明显高于对照组（8.2毫米对5.8毫米；P小于0.001）。Lamicel组（n = 270）观察到1例穿孔，而对照组（n = 359）观察到6例穿孔（无统计学意义）。两组再次入院频率无差异。在一年的临床经验中，使用Lamicel进行选择性流产术前治疗，并未降低围手术期和术后并发症发生率。
