Previous data indicate that patients who undergo surgery with a postgraduate year 3 (PGY-3) resident as the junior surgeon have a lower rate of recurrence compared with PGY-1 and PGY-2 after an open inguinal herniorrhaphy. Lower PGY level was also associated with increased operative time. We hypothesize that when controlling for surgeon, technique, and hernia type, the outcomes for inguinal herniorrhaphy are the same independent of PGY level.
A retrospective review of all open unilateral inguinal hernia repairs done by residents who assisted the same senior surgeon at the Veterans Affairs North Texas Health Care System was performed.
Seven hundred fifty-two open unilateral inguinal hernia were identified: mean patient age = 60.6 ± 12.7 y; mean body mass index = 27.0 ± 10.8 kg/m; American Society of Anesthesia III-IV = 51%; and Nyhus type 2 = 44.7%, 3a = 41.6%, and 3b = 13.7%. Residents involved were PGY-1 (17.2%), PGY-2/3 (71.1%), and PGY-4/5 (11.7%). Postoperative complications for intern, junior (PGY-2 and PGY-3), and senior residents (PGY-4 and PGY-5) were 4%, 9%, and 6%, respectively (P = 0.14). Compared to interns, junior residents finished the operation 3.9 min faster (95% confidence interval = -7.5, -0.3). There was no time difference between interns and senior residents completing the operations after controlling for hernia type. Logistic regression did not identify PGY level as an independent predictor of complications or recurrence.
There was a slight decrease in operative time when the repair was done with junior-level residents. PGY level did not influence outcomes for open, unilateral inguinal herniorrhaphy when controlled for hernia type and technique.
既往数据表明,在开放式腹股沟疝修补术后,由三年级住院医师(PGY-3)作为初级外科医生进行手术的患者,其复发率低于PGY-1和PGY-2的患者。较低的PGY水平也与手术时间延长有关。我们假设,在控制外科医生、技术和疝类型的情况下,腹股沟疝修补术的结果与PGY水平无关。
对在北德克萨斯退伍军人事务医疗系统中协助同一位资深外科医生的住院医师所进行的所有开放式单侧腹股沟疝修补术进行回顾性研究。
共识别出752例开放式单侧腹股沟疝:患者平均年龄=60.6±12.7岁;平均体重指数=27.0±10.8kg/m;美国麻醉医师协会III-IV级=51%;Nyhus 2型=44.7%,3a型=41.6%,3b型=13.7%。参与的住院医师为PGY-1(17.2%)、PGY-2/3(71.1%)和PGY-4/5(11.7%)。实习医生、初级住院医师(PGY-2和PGY-3)和高级住院医师(PGY-4和PGY-5)的术后并发症发生率分别为4%、9%和6%(P=0.14)。与实习医生相比,初级住院医师完成手术的时间快3.9分钟(95%置信区间=-7.5,-0.3)。在控制疝类型后,实习医生和高级住院医师完成手术的时间没有差异。逻辑回归未将PGY水平确定为并发症或复发的独立预测因素。
由初级住院医师进行修补时,手术时间略有缩短。在控制疝类型和技术的情况下,PGY水平不影响开放式单侧腹股沟疝修补术的结果。
