Laparoscopic myomectomy (LM) offers considerable advantages over open myomectomy; however, LM is technically complex and associated with a steep learning curve. Few studies have evaluated the effect of the learning curve, and the limitations of most of these studies were the number of women included and the multiplicity of surgeons undertaking the procedure. The aim of this study is to evaluate the effect of a caseload of 100 patients during the learning curve of a single experienced surgeon performing LM.
A prospective comparative analysis of 200 consecutive cases of LM was conducted between December 2004 and March 2013. Outcomes of the first 100 procedures (Group A) were compared with the later 100 (Group B).
The mean age of the cohort was 39 years (24-54 years), with a mean BMI of 27 kg/m(2) (16-46). Both the groups were very similar with regard to the number, size and weight of myomas removed, the duration of surgery, and blood loss. More women were sent home within 24 h in the second group (27 vs 10.2 %, p = 0.002). Group A suffered significantly higher complication rates compared to Group B (11 vs 7, p < 0.05). The laparotomy conversion rate was 1.5 % (3 in Group A, none in Group B).
After a caseload of 100 patients during the learning curve, there was no difference in outcomes apart from increased confidence to discharge patients after 24 h and reduced complication rates. Thus, mere numbers do not influence the number/size of fibroids removed, operating time, or blood loss but do influence complication rates and post-operative discharge times.
腹腔镜子宫肌瘤切除术(LM)相比开腹子宫肌瘤切除术具有诸多显著优势;然而,LM技术复杂且学习曲线陡峭。很少有研究评估学习曲线的影响,并且这些研究大多存在样本量有限以及参与手术的外科医生多样等局限性。本研究旨在评估在一名经验丰富的外科医生进行LM的学习曲线期间,100例病例的手术量所产生的影响。
对200例连续的LM病例进行前瞻性对比分析,时间跨度为2004年12月至2013年3月。将前100例手术的结果(A组)与后100例(B组)进行比较。
该队列的平均年龄为39岁(24 - 54岁),平均体重指数为27kg/m²(16 - 46)。两组在切除肌瘤的数量、大小和重量、手术时长以及失血量方面非常相似。第二组中有更多女性在24小时内出院(27%对10.2%,p = 0.002)。与B组相比,A组的并发症发生率显著更高(11例对7例,p < 0.05)。剖腹手术转化率为1.5%(A组3例,B组无)。
在学习曲线期间完成100例病例的手术量后,除了24小时后出院信心增加和并发症发生率降低外,其他结果并无差异。因此,单纯的手术量并不影响切除肌瘤的数量/大小、手术时间或失血量,但会影响并发症发生率和术后出院时间。
