The adverse outcomes of laparoscopic fundoplication are more likely during the initial 20 cases performed by each individual surgeon. This study aimed to evaluate the impact of substantial surgical experience versus experience beyond the learning curve on the early and late objective and subjective results.
The patients were divided into two groups according to the surgeon. In group 1 (n = 230), all the patients underwent surgery by a surgeon with substantial experience in laparoscopic fundoplication. In group 2 (n = 118), the patients were treated by a total of seven surgeons whose personal experience exceeded the individual learning curve, but was distinctively less than that of the group 1 surgeon.
The conversion rate was 2.2% in group 1 and 4.4% in group 2. The median operating time was 65 min in group 1 and 70 min in group 2 (p = 0.0020). The occurrence of immediate complications was 3.5% in group 1 and 7.6% in group 2 (p = 0.0892). At 6 months after surgery, 7.4% of the patients in group 1 and 16.1% of the patients in group 2 reported that dysphagia disturbed their daily lives (p = 0.0115). The late subjective results, including postoperative symptoms and evaluation of the surgical result, were similar in the two groups.
Substantial experience with the procedure is associated with a shorter operating time and somewhat fewer complications, conversions, and early dysphagia episodes. This supports the provision of expert supervision even after the initial learning phase of 20 individual procedures. The patients' long-term subjective symptomatic outcome was similar in the two groups. Substantial experience does not provide better late results than surgical experience beyond the learning curve.
每位外科医生开展的最初20例腹腔镜胃底折叠术的不良结局更为常见。本研究旨在评估丰富的手术经验与超越学习曲线的经验对早期和晚期客观及主观结果的影响。
根据手术医生将患者分为两组。第1组(n = 230),所有患者均由一位在腹腔镜胃底折叠术方面经验丰富的外科医生进行手术。第2组(n = 118),患者由总共7位外科医生治疗,他们个人的经验超过了个体学习曲线,但明显少于第1组外科医生的经验。
第1组的中转率为2.2%,第2组为4.4%。第1组的中位手术时间为65分钟,第2组为70分钟(p = 0.0020)。第1组即刻并发症的发生率为3.5%,第2组为7.6%(p = 0.0892)。术后6个月,第1组7.4%的患者和第2组16.1%的患者报告吞咽困难影响了他们的日常生活(p = 0.0115)。两组的晚期主观结果,包括术后症状和手术结果评估,相似。
丰富的手术经验与较短的手术时间以及稍少的并发症、中转率和早期吞咽困难发作相关。这支持即使在完成20例个体手术的初始学习阶段后仍提供专家监督。两组患者的长期主观症状结局相似。丰富的经验并不比超越学习曲线的手术经验带来更好的晚期结果。
