title: [Comparison of postoperative residue, recurrence and pregnancy outcome between laparoscopic and transabdominal myomectomy].
abstract: OBJECTIVE
  To compare operative characteristics, postoperative residue, recurrence, and pregnancy outcome between laparoscopic myomectomy (LM) and transabdominal myomectomy (TAM), and investigate the favourable surgical approach in women with uterine myomas.
  
  
  METHODS
  From Jan 2008 to Dec 2008, 313 women undergoing LM and 148 women undergoing TAM were studied retrospectively in Peking Union Medical College Hospital. The patients' general information, including the largest diameter, mean numbers and weights of excised myomas, peri-operative characteristics (operating time, blood loss, and hemoglobin decrease), and residue, recurrence of myoma, and pregnancy outcome were compared and analyzed.
  
  
  RESULTS
  The largest diameter, mean numbers and mean weight of myomas removed were larger in TAM group [(7.6 ± 3.0) cm, (5.6 ± 5.5), (308 ± 364) g, respectively] than those in LM group [(6.8 ± 2.0) cm, (2.4 ± 2.1), (140 ± 109) g, respectively; P < 0.01]. While the extension of operating time [(89 ± 32) versus (74 ± 35) min], increased blood loss [(239 ± 251) versus (149 ± 252) ml] and hemoglobin decrease [(22 ± 14) versus (15 ± 12) g/L], and longer hospital stay [(6.4 ± 1.6) versus (4.4 ± 1.3) d] were observed in TAM group when compared with those in LM group (P < 0.01). However, the residue rate of LM and TAM was 2.6% versus 1.4% respectively (P = 0.5130); the recurrence rate of LM and TAM was 11.1% versus 12.3% (P > 0.05); the pregnancy rate of LM and TAM was 49.2% versus 9/13 separately, the difference was not statistically significant (P = 0.2330). The number of myomas removed was the significant risk factors associated with recurrence (OR = 2.805, 95%CI: 1.192 - 6.601, P = 0.0180). No uterine rupture occurred during pregnancy.
  
  
  CONCLUSIONS
  Both LM and TAM are effective surgical approaches for the patients with leiomyoma who desire to pregnancy, or to retain the integrity of their uteruses. Most of uterine myoma could be treated through laparoscopy. The residue rate of LM is higher than that of TAM. However, the short term recurrence rates of LM and TAM are similar. Multiple myomas is the risk factor associated with recurrence after myomectomy. The pregnancy rates are comparable between LM and TAM groups.
