Expectant versus surgical management of first-trimester miscarriage: a randomised controlled study.

Abstract

INTRODUCTION:

The aim of this study is to compare the efficacy and safety of expectant management with surgical management of first-trimester miscarriage.

METHODS:

This randomised prospective study was conducted in the Gynaecology Department at University of Saarland Hospital, Germany between February 2011 and April 2012. A total of 234 women were recruited following diagnosis of the first-trimester incomplete or missed miscarriage and randomised into two groups: 109 women were randomised to expectant management (group I), and 125 women to surgical management (groupII). All women were examined clinically and sonographically during the follow-up appointments at weekly intervals for up to 4 weeks as appropriate. The outcome measures were: efficacy, short-term complications and duration of vaginal bleeding and pain.

RESULTS:

Of 234 eligible women, 17 were lost to follow-up, and the remaining 217 women were analysed. The baseline characteristics were similar in both groups. The total success rate at 4 weeks was lower for expectant than for surgical management (81.4 vs 95.7 %; P = 0.0029). The type of miscarriage was a significant factor affecting the success rate. For missed miscarriage, the success rates for expectant versus surgical management were 75 and 93.8 %, respectively. For women with incomplete miscarriage, the rates were 90.5 and 98 %. No differences were found in the number of emergency curettages between the two study groups. The duration of bleeding was significantly more in the expectant than the surgical management (mean 11 vs 7 days; P < 0.0001). The duration of pain was also more in the expectant than the surgical group (mean 8.1 vs 5.5 days; P < 0.0001). The total complication rates were similar in both groups (expectant 5.9 % vs surgical group 6.1 %; P = 0.2479). However, the pelvic infection was significantly lower in the expectant than the surgical group (1.9 vs 3.5 %, respectively; P = 0.0146).

CONCLUSION:

Expectant management of clinically stable women with first-trimester miscarriage is safe and effective and avoids the need for surgery and the subsequent risk of anaesthesia in about 81.4 % of cases, and has lower pelvic infection rate than surgical curettage. However, surgical management is more successful, and with a shorter duration of bleeding and pain. Therefore, the patient's preference should be considered in the counselling process.
