Background:Many previous studies have suggested that the number of lymph nodes retrieved should serve as a benchmark for assessing the adequacy of the resection. The aim was to retrospectively observe the impact of nodal retrieval after educating the pathologist.Methods:Patients undergoing a pancreaticoduodenectomy (PD) between September 2005 and March 2009 were included in the study. The PDs performed between September 2005 and March 2008 were designated as Group A. The pathologistswere educated regarding the importance of nodal counts in PD by the surgeon on the 1st April 2008. PDs performed betweenApril 2008 and March 2009 were designated as Group B.Results:Ninety-eight PDs performed by a single surgeon (D.R.J.) for peri-ampullary malignancy were evaluated. The median number of lymph nodes retrieved in Group A was 11(3–32) nodes. The median number of lymph nodes retrieved in Group B was 22 (10–29) nodes (P < 0.001).The lymph node ratio (positive/total nodes), median number of positive nodes retrieved, and the node positivity (node positive compared to node negative) rate did not change.Discussion:A single intervention with the pathologists did impact the number of lymph nodes retrieved from PD specimens. However, the lymph node ratio and lymph node positivity rate remained unchanged. The pathologist is critical to nodal retrieval in PD, but the use of this lymph node number for benchmark of surgical adequacy may be simplistic. 相似文献

IntroductionThe purpose of this study was to document the variability of faculty surgeon electrodermal activity (EDA) peaks during laparoscopic donor nephrectomy (LDN) to determine the effect of case difficulty and learner expertise on the stress response.MethodsEDA for a single faculty surgeon was captured over 15 LDN cases using an Empatica E4 wristband. During each case, one of three transplant fellows (novice, intermediate, or expert level LDN expertise) participated. Difficulty was rated preoperatively as “low/moderate/high” by the faculty. EDA peaks were collected and analyzed; the frequency and magnitude of EDA peaks, case difficulty, and fellow expertise were compared using a two-way factorial ANOVA.ResultsThe main effects of learner expertise (F[2, 308]=11.27, p<0.001) and difficulty rating (F[2, 414]=15.13, p<0.001) were significant. The interaction between difficulty and expertise on faculty EDA peaks was also significant (F[3, 391]=14.29, p<0.001). The novice fellow resulted in higher faculty EDA levels compared to intermediate and expert fellows on low-difficulty cases, but not moderate- or high-difficulty cases.ConclusionsThis is the first report examining faculty surgeon EDA across cases of varying difficulty and varying learner expertise during a high-stakes operation. EDA levels were inversely proportional to the expertise of the learner and case difficulty, suggestive of a significant impact of learner autonomy on faculty stress response. 相似文献
