New laparoscopic techniques introduced after residency have created a new teaching paradigm focused on animate courses and preceptor instruction. The aim of this study was to test the effectiveness of animate course instruction in teaching laparoscopic ventral hernia repair (LVHR), its success in relationship to the course participants' previous minimally invasive surgery experience, and the role of preceptors in adapting these techniques.
Surgeons participating in a one-day LVHR course (lectures/animal laboratory) at the Carolinas Medical Center were surveyed concerning professional demographics, prior laparoscopic experience, and their performance of LVHR before and after the encounter. Standard statistics were used to determine significance (P<0.05).
Of the 234 surgeons attending a LVHR course between 1999 and 2004, 171 (73%) answered the survey. Mean follow-up after the course was 427 days (range: 34-1202 d). Mean age was 45.9 years (range: 28-67 y). Mean time since residency was 14.4 years (range: 0.5-37 y), and 106 (62%) had learned at least basic laparoscopy in residency. One hundred twenty-six (73.7%) were in private practice. Since the course, 122 (71.3%) had performed a LVHR. They had performed a total of 2049 LVHRs (mean: 16.5; range: 1-102) compared with 1098 open herniorrhaphies (mean: 9; range: 1-23). There was no difference between those performing and not performing LVHR or the number executed with respect to practice type (P=0.67), age (P=0.47), years in practice (P=0.19), or laparoscopic experience in residency (P=0.42). Fifty-four (32%) surgeons had been precepted, and all have since performed LVHR. Surgeons with advanced laparoscopic experience were more likely to perform LVHR compared with those with only laparoscopic cholecystectomy experience (87% versus 33%, P=0.02). Indeed, of those with only laparoscopic cholecystectomy experience who performed LVHR, 80% were precepted. In the subset of surgeons who had not yet performed LVHR, 28 intended to start, 17 requested assistance, and 4 planned not to begin.
A one-day course impacts surgeon practice patterns despite age or type of practice. Surgeons with advanced laparoscopic skills are more likely to perform LVHR. Most with limited experience will begin after working with a preceptor. Didactic instruction and a precepted experience may determine the future performance of advanced laparoscopy.
住院医师培训结束后引入的新型腹腔镜技术创造了一种新的教学模式,该模式侧重于动画课程和带教指导。本研究的目的是测试动画课程教学在腹腔镜腹疝修补术(LVHR)教学中的有效性,其与课程参与者先前微创手术经验相关的成功率,以及带教老师在应用这些技术中的作用。
对参加卡罗来纳医疗中心为期一天的LVHR课程(讲座/动物实验室)的外科医生进行了调查,内容涉及专业人口统计学、先前的腹腔镜经验以及他们在参加课程前后的LVHR手术表现。使用标准统计学方法确定显著性(P<0.05)。
在1999年至2004年间参加LVHR课程的234名外科医生中,171名(73%)回答了调查。课程后的平均随访时间为427天(范围:34 - 1202天)。平均年龄为45.9岁(范围:28 - 67岁)。自住院医师培训结束后的平均时间为14.4年(范围:0.5 - 37年),106名(62%)在住院医师培训期间至少学习了基本的腹腔镜检查。126名(73.7%)为私人执业。自课程结束后,122名(71.3%)进行了LVHR手术。他们总共进行了2049例LVHR手术(平均:16.5例;范围:1 - 102例),相比之下,开放疝修补术为1098例(平均:9例;范围:1 - 23例)。在进行和未进行LVHR手术的医生之间,或者就手术类型(P = 0.67)、年龄(P = 0.47)、执业年限(P = 0.19)或住院医师培训期间的腹腔镜经验(P = 0.42)而言,手术例数没有差异。54名(32%)外科医生接受过带教指导,此后他们都进行了LVHR手术。与仅具有腹腔镜胆囊切除术经验的外科医生相比,具有高级腹腔镜经验的外科医生更有可能进行LVHR手术(87%对33%,P = 0.02)。实际上,在仅具有腹腔镜胆囊切除术经验且进行了LVHR手术的医生中,80%接受过带教指导。在尚未进行LVHR手术的外科医生子集中,28名打算开始,17名请求协助,4名计划不开始。
为期一天的课程会影响外科医生的手术模式,无论其年龄或执业类型如何。具有高级腹腔镜技能的外科医生更有可能进行LVHR手术。大多数经验有限的医生在与带教老师合作后会开始进行。理论教学和带教经验可能决定高级腹腔镜手术的未来开展情况。
