RESUMEN

BACKGROUND: International medical graduates (IMGs) are often relegated to preliminary positions in general surgery (GS) owing to uncertainties about the candidate's performance in the American healthcare setting. We aimed to determine the comparative performance of IMGs and American medical graduates (AMGs) at baseline and assess these trends over the course of their GS internship. METHODS: Evaluations of all IMG preliminary and AMG categorical interns from 2013 to 2017 at our GS residency program were obtained from three faculty members to score overall performance, technical skills, interpersonal communication, and medical knowledge on a 10-point Likert scale. Scores on the American Board of Surgery In-Training Exam, an in-house preparation test, United States Medical Licensing Exam, and performance during the biannual multistation objective assessments were compared between the two resident groups. RESULTS: Seventy-two interns (28 [39%] AMG categorical and 44 [61%] IMG preliminary) met inclusion criteria. The AMG group had significantly higher median Step 1 and Step 2 scores compared with our IMG group (243 versus 231, P = 0.002, and 250 versus 246, P = 0.03, respectively).Although in-house preparation test scores were higher among IMGs (median [interquartile range] of 36 [33-40] among AMGs and 38 [34-45] among IMGs; P = 0.002), there were no statistically significant differences between the American Board of Surgery In-Training Exam scores of the two groups. The median scores for the four faculty evaluation components were similar between the AMG (7, 8, 7, 7) and IMG resident groups (7, 7, 7, 7; P = nonsignificant). IMGs scored significantly higher in both biannual multistation objective assessments than AMGs (median [interquartile range] July: 59 [47-91] versus 55 [37-62], P = 0.005; January: 103 [86-116] versus 91 [87-104], P = 0.03). CONCLUSIONS: It is reassuring to confirm that no matter where they are from, great candidates can perform well as surgical interns in a GS training program.

RESUMEN

BACKGROUND: Bilateral adrenalectomy (BA) is a curative treatment for hypercortisolism in patients with corticotropin (ACTH)-dependent Cushing syndrome. Indications include refractory Cushing's disease (CD) following failed pituitary surgery, and occult or unresectable ectopic ACTH-producing neoplasms (EA). METHODS: This was a single-center, retrospective review (1995-2017) of patients undergoing BA for CD or EA. Demographics, laboratory findings, and intraoperative and postoperative variables were analyzed. RESULTS: Of 137 patients, 83 (61%) had CD and 54 (39%) had EA; 87% of CD patients were female versus 46% of EA patients (p < 0.0001). Mean age at diagnosis was 40 ± 15 years for CD and 49 ± 18 years for EA (p = 0.004). Preoperative serum cortisol concentrations were higher in the EA cohort (63 ± 40 µg/dL) versus the CD cohort (33 ± 19 µg/dL) [p < 0.001], with no significant differences in serum ACTH. Time from diagnosis until adrenalectomy was 54 ± 69 months for CD versus 4 ± 13 for EA (p = 0.002). Most patients underwent minimally invasive surgery (MIS; 86% CD vs. 75% EA; p = 0.19). There was no difference between the rates of conversion to an open approach, intraoperative blood loss, or operative time between groups, and no difference between complications in CD versus EA (p = 1.0). Five-year survival was significantly shorter among the EA cohort (30% for EA vs. 80% for CD; p < 0.001). CONCLUSION: Patients with EA presented with higher serum cortisol levels compared with patients with CD. EA patients were more likely to require intraoperative transfusion and postoperative intensive care. BA in patients with CD and EA can be performed safely in an MIS fashion, with similar morbidity; however, survival at 5 years was significantly less in the EA cohort.

RESUMEN

BACKGROUND: Breast surgery has evolved with more focus on improving cosmetic outcomes, which requires increased operative time and technical complexity. Implications of these technical advances in surgery for the surgeon are unclear, but they may increase intraoperative demands, both mentally and physically. We prospectively evaluated mental and physical demand across breast surgery procedures, and compared surgeon ergonomic risk between nipple-sparing (NSM) and skin-sparing mastectomy (SSM) using subjective and objective measures. METHODS: From May 2017 to July 2017, breast surgeons completed modified NASA-Task Load Index (TLX) workload surveys after cases. From January 2018 to July 2018, surgeons completed workload surveys and wore inertial measurement units to evaluate their postures during NSM and SSM cases. Mean angles of surgical postures, ergonomic risk, survey items, and patient factors were analyzed. RESULTS: Procedural duration was moderately related to surgeon frustration, mental and physical demand, and fatigue (p < 0.001). NSMs were rated 23% more physically demanding (M = 13.3, SD = 4.3) and demanded 28% more effort (M = 14.4, SD = 4.6) than SSMs (M = 10.8, SD = 4.7; M = 11.8, SD = 5.0). Incision type was a contributing factor in workload and procedural difficulty. Left arm mean angle was significantly greater for NSM (M = 30.1 degrees, SD = 6.6) than SSMs (M = 18.2 degrees, SD = 4.3). A higher musculoskeletal disorder risk score for the trunk was significantly associated with higher surgeon physical workload (p = 0.02). CONCLUSION: Nipple-sparing mastectomy required the highest surgeon-reported workload of all breast procedures, including physical demand and effort. Objective measures identified the surgeons' left upper arm as being at the greatest risk for a work-related musculoskeletal disorder, specifically from performing NSMs.

RESUMEN

BACKGROUND: Our group has shown that personalized video feedback (PVF) is better than a task demonstration video at increasing wound closure skills among incoming surgical interns. However, offering PVF can be time-consuming. We sought to compare the educational effects and time required for group video feedback (GVF) and PVF. METHODS: We have mailed our matched incoming "surgical" interns a "welcome package" in mid-March for the past 3 y. The package includes similar resources each year. Incoming interns were asked to video record themselves performing six tasks three separate times between April 1 and June 15. After each submission in 2016 and 2017, incoming interns received 2 min of personalized feedback on their three separate wound closure videos (PVF). In 2018, incoming interns received 5 min of group-based feedback three separate times covering all six tasks (GVF). We compared performance (July Surgical Olympics) of these six skills against the interns from the previous 2 y who received PVF on only one skill (suturing). RESULTS: Twenty-three incoming interns received the pre-residency package and participated in the 2018 Surgical Olympics. This 2018 GVF class had a higher overall mean score for six stations (31.5 [standard deviation = ±7.7]) than the 2016 and 2017 PVF classes (25.6 [standard deviation = ±8]; P < 0.0001). Knot tying ability and suturing skill were similar between the classes. The GVF group performed better on the remaining four skills . The total time of surgical staff and educators spent per class in 2018 (GVF class) was 30 min and includes six tasks compared with 276 min of effort in each of the 2016 and 2017 classes (PVF included one task). CONCLUSIONS: GVF and PVF as a component of preemptive training had the same effect on improving suturing skills among the interns. GVF required less educator editing and voice over time. GVF is effective and efficient in enhancing incoming interns' performance in multiple skills.

RESUMEN

Purpose: Compare time (speed) and product quality goals in a surgical procedural task.Methods: Secondary school students participating in a medical simulation-based training activity participated in a randomized experiment. Each participant completed eight repetitions of a blood vessel ligation. Once, between repetitions four and five, each participant received a randomly-assigned speed goal or quality goal. Outcomes included time and leak-free ligatures.Results: 80 students participated. The speed-goal group performed 18% faster on the final repetition than the quality-goal group, with adjusted fold change (FC) 0.82 (95% confidence interval [CI], 0.71, 0.94; p = 0.01). Conversely, the speed-goal group had fewer high-quality (leak-free) ligatures (odds ratio [OR] 0.36 [95% CI, 0.22, 0.58; p < 0.001]). For the quality-goal group, leaky ligatures took longer post-intervention than leak-free ligatures (FC 1.09 [95% CI, 1.02, 1.17; p = 0.01]), whereas average times for leaky and leak-free ligatures were similar for the speed-goal group (FC 0.97 [95% CI, 0.91, 1.04; p = 0.38]). For a given performance time, the speed-goal group had more leaks post-intervention than the quality-goal group (OR 3.35 [95% CI, 1.58, 7.10; p = 0.002]).Conclusions: Speed and quality goals promote different learning processes and outcomes among novices. Use of both speed and quality goals may facilitate more effective and efficient learning.

RESUMEN

BACKGROUND: Adrenalectomy for non-neuroblastic pathologies in children is rare with limited data on outcomes. We reviewed our experience of adrenalectomy in this unique population. METHODS: Retrospective study of children (age ≤ 18) who underwent adrenalectomy with non-neuroblastic pathology from 1988 to 2018. Clinical and operative details of patients were abstracted. Outcomes included length of stay and 30-day postoperative morbidity. RESULTS: Forty children underwent 50 adrenalectomies (12 right-sided, 18 left-sided, 10 bilateral). Six patients (15%) presented with an incidental adrenal mass while 4 (10%) had masses found on screening for genetic mutations or prior malignancy. The remaining 30 (75%) presented with symptoms of hormonal excess. Nineteen patients (48%) underwent genetic evaluation and 15 (38%) had genetic predispositions. Diagnoses included 9 patients (23%) with pheochromocytoma, 8 (20%) with adrenocortical adenoma, 8 (20%) with adrenocortical carcinoma, 7 (18%) with adrenal hyperplasia, 2 (5%) with metastasis, and 6 (14%) with additional benign pathologies. Of 50 adrenalectomies, twenty-five (50%) were laparoscopic. Median hospital length of stay was 3 days (range 0-11). Post-operative morbidity rate was 17% with the most severe complication being Clavien-Dindo grade II. CONCLUSION: Adrenalectomy for non-neuroblastic pathology can be done with low morbidity. Its frequent association with genetic mutations and syndromes requires surgeons to have knowledge of appropriate pre-operative testing and post-operative surveillance.

RESUMEN

OBJECTIVE: To Identify predictors of recurrent disease following lateral neck dissection (LND) for papillary thyroid carcinoma (PTC). METHODS: A retrospective review of patients who underwent first-time LND for PTC at our institution (2000-2015) was performed. Medical records were examined for biopsy or pathologically proven lateral neck recurrence. Differences between the groups with and without recurrence were compared. All LNDs were then classified in to two groups: "comprehensive" (CND), involving levels IIa-Vb at minimum, or "selective", labelling less extensive dissection (SND). RESULTS: Four hundred nine patients underwent 467 LNDs. Surveillance data were available for 317 patients who underwent 362 LNDs (mean age 45 ± 16; range 18-88). The median follow-up was 64 ± 48 months (range 3-197). Recurrence was detected in 71 lateral necks (20%). The total number of lymph nodes was greater in the group without recurrence compared to those with recurrence (23 vs. 19, p = 0.02). Among patient demographics, radioactive iodine treatment, primary tumor characteristics and characteristics of nodal metastases, only an older patient age (mean 50 vs. 43 years) was associated with lateral neck recurrence (p < .01). CND was performed in 102 lateral necks and SND in 143 necks. There were 12 recurrences recorded in the CND group (12%) vs. 31 in the SND group (22%, p = .04). The majority of recurrences (70%) involved levels included in the original dissection. CONCLUSIONS: Younger patients, more extensive dissection and a higher total number of lymph nodes removed are associated with a lower incidence of lateral neck recurrence after LND for papillary thyroid carcinoma.

RESUMEN

BACKGROUND: Surgeons and gastroenterologists in training benefit from simulation-based endoscopy education, yet the price of most training endoscopy simulators is prohibitive. We set out to create and evaluate a low-cost endoscopic simulator and box model trainer for learning fundamental endoscopic skills. METHODS: After adding a wireless network-enabled camera (total cost, $20) to a discarded clinical endoscope, we paired this with an easily constructed box trainer (cost $32) to generate an endoscopic simulator system (YazanoScope) for simulation training. Participants (general surgery interns, research fellows, and medical and college students) used the YazanoScope to train to mastery on 5 FES tasks. Outcomes included skill assessments on a computer simulator and trainees' perceptions comparing the physical model to the computer simulator. RESULTS: Forty trainees participated. The median (range) training time was 110 (60-180) min. Only 10% of trainees were able to reach the cecum at baseline compared to 100% after training. The mean (SD) time was 253 (154) s at baseline (including completers and non-completers) and 249 (89) after training (P = 0.88). On a retention test 2 wk later, 21 of 22 (96%) completed the computer simulator assessment (endoscope tip reached the cecum). Mean time was 214 (67) s (P = 0.32 compared with immediate posttraining). All 40 trainees believed the YazanoScope provided better haptic feedback than the computer simulator. CONCLUSIONS: Training with this inexpensive, portable endoscopic simulator (YazanoScope) was associated with increased procedure completion with no change in procedure time. All participants favored the haptic feedback of the $52 YazanoScope over a computer simulator.

RESUMEN

BACKGROUND: Indocyanine green fluorescence angiography (ICGA) is a new adjunct that has been used in surgical procedures to assess blood flow. This study evaluated the utility of ICGA compared to visual inspection to predict parathyroid function, guide autotransplantation and potentially decrease permanent hypoparathyroidism. METHODS: This was a retrospective study of patients who underwent total or near-total thyroidectomy (T-NT) between January 2015 and March 2018. Patients with preoperative hyperparathyroidism and those undergoing reoperation were excluded. Patients who had ICGA were compared to T-NT patients without ICGA. Data were analyzed to assess the frequency of autotransplantation and incidence of hypoparathyroidism between groups. RESULTS: In total, 210 patients underwent T-NT: 86 with ICGA and 124 without. Autotransplantation was more common in the ICGA group at 36% compared to 12% in the control (p = 0.0001). There was no correlation with at least one normal parathyroid gland on ICGA and postoperative PTH levels (p = 0.75). There was a difference in having normal postoperative PTH when there were at least two normal parathyroid glands (n = 50) compared to patients with less than two normal ICGA glands (n = 36, p = 0.044). Visual assessment and ICGA assessment of vascularity were in agreement, 245/281 (87%). There were 19 glands (6.8%) that would have undergone autotransplant based on visual inspection that had adequate blood supply on ICGA. Transient hypoparathyroidism was present in 45 out of 124 controls (36%) and 32 out of 86 (37%) in the ICG group. CONCLUSIONS: ICGA is a novel technique that may improve the assessment of parathyroid gland blood supply compared to visual inspection. ICGA can guide more appropriate autotransplantation without compromising postoperative parathyroid function. At least two vascularized glands on ICGA may predict postoperative parathyroid gland function.

RESUMEN

INTRODUCTION: Patients undergoing unilateral adrenalectomy for primary aldosteronism (PA) may have a solitary adenoma, unilateral hyperplasia, or multiple adenomas on final pathology. This study investigated whether the underlying pathological diagnosis was associated with differences in clinical presentation and postoperative outcomes. METHODS: A retrospective cohort study of patients undergoing unilateral adrenalectomy for PA from 2004 to 2015 at our institution was performed. Baseline clinical and laboratory parameters, as well as postoperative biochemical and hypertension cure rates, were compared across the three aforementioned pathological groups. RESULTS: Of 206 patients who met criteria for inclusion, 152 (73.8%) had a single adenoma, 33 (16%) had unilateral hyperplasia, and 21 (10.2%) had multiple unilateral adenomas. Patients with unilateral hyperplasia were more likely to be male (81.2% vs 57.9%, P = .03), undergo left-sided adrenalectomy (78.8% vs 47.4%, P < .01), and had a lower median adrenal venous sampling lateralization index (9.8 vs 19.8, P = .04) compared to those with solitary, but not multiple unilateral adenomas. No differences were seen in age, duration of hypertension, preoperative plasma aldosterone levels, plasma renin activities, 24-h urinary aldosterone excretion, serum potassium concentrations, and the number of preoperative antihypertensive medications across all three pathological groups. All patients achieved biochemical cure following adrenalectomy, and no significant differences in the rates of hypertension cure or improvement were observed in comparisons across pathological subtype. CONCLUSIONS: Clinical presentation and postoperative outcomes are similar regardless of underlying pathology in patients with PA. Because one in four patients may harbor unilateral hyperplasia or multiple adenomas, total unilateral adrenalectomy should be performed as the operation of choice over adrenal-sparing approaches.

RESUMEN

Self-regulated learning is optimized when instructional supports are provided. We evaluated three supports for self-regulated simulation-based training: practice schedules, normative comparisons, and learning goals. Participants practiced 5 endoscopy tasks on a physical simulator, then completed 4 repetitions on a virtual reality simulator. Study A compared two practice schedules: sequential (master each task in assigned order) versus unstructured (trainee-defined). Study B compared normative comparisons framed as success (10% of trainees were successful) versus failure (90% of trainees were unsuccessful). Study C compared a time-only goal (go 1 min faster) versus time + quality goal (go 1 min faster with better visualization and scope manipulation). Participants (18 surgery interns, 17 research fellows, 5 medical/college students) were randomly assigned to groups. In Study A, the sequential group had higher task completion (10/19 vs. 1/21; P < .001), longer persistence attempting an ultimately incomplete task (20.0 vs. 15.9 min; P = .03), and higher efficiency (43% vs. 27%; P = .02), but task time was similar between groups (20.0 vs. 22.6 min; P = .23). In Study B, the success orientation group had higher task completion (10/16 vs. 1/24; P < .001) and longer persistence (21.2 vs. 14.6 min; P = .001), but efficiency was similar (33% vs. 35%; P = .84). In Study C, the time-only group had greater efficiency than time + quality (56% vs. 41%; P = .03), but task time did not differ significantly (172 vs. 208 s; P = .07). In this complex motor task, a sequential (vs. unstructured) schedule, success (vs. failure) orientation, and time-only (vs. time + quality) goal improved some (but not all) performance outcomes.

RESUMEN

BACKGROUND: Criteria for diagnosing primary hyperparathyroidism (PHPT) include hypercalcemia in the presence of parathyroid hormone (PTH) levels that are either elevated (classic PHPT) or normal but non-suppressed. However, there is no standard definition of what constitutes normal non-suppressed levels, and data are lacking regarding the potential for surgical cure in these patients. METHODS: A retrospective review of patients undergoing parathyroidectomy for sporadic PHPT between 2012 and 2014 was performed. Patients with normal PTH were compared to classic PHPT patients to assess demographics, imaging, operative findings, and outcomes. RESULTS: In total, 332 patients met study criteria, and 60 (18%) had normal PTH levels. Negative sestamibi scans were seen more often with normal PTH levels (18.3 vs. 4.8%, p < 0.001). Patients with normal PTH were more likely to have ≥2 glands removed (26.7 vs. 14.3%, p = 0.02), and the specimens were more likely to be classified as only mildly hypercellular or normocellular (20 vs. 2.9%, p < 0.001). Average follow-up was 24 months (range 6-55). Cure rate was 88% in the normal PTH group, compared to 96% in classic PHPT (p = 0.02). Among patients with normal PTH, those with PTH ≤ 55 pg/mL had an 83% cure rate, whereas those with PTH 56-65 had a 96% cure rate (p = 0.12). CONCLUSIONS: Parathyroidectomy can have a high cure rate in the context of normal PTH levels despite an increased likelihood of negative imaging and multigland resection. Operative success is equivalent to classic PHPT when PTH levels are > 55 pg/mL.

RESUMEN

BACKGROUND: Papillary thyroid carcinoma (PTC) is frequently associated with cervical lymph node metastases. Guidelines recommend performing ultrasound-guided fine-needle aspiration cytology (FNAC) for suspicious nodes to guide management. No specific recommendations are available for the use of FNA thyroglobulin assay (FNA-Tg). This study investigated the diagnostic value of performing FNAC and FNA-Tg. METHODS: Patient demographics, preoperative investigations, surgery, and lymph node pathology were collected for patients with PTC who underwent lateral neck lymphadenectomy and central compartment reexploration from January 2000 to July 2015. Sensitivities and accuracies were obtained. Patients with both diagnostic studies performed were compared using McNemar's test of paired proportion. Patient, imaging, and lymph node characteristics were correlated with test accuracy. RESULTS: The 480 patients in this study underwent 706 lateral neck dissections or central compartment reexploration. All the patients underwent preoperative neck ultrasound. Among these patients, FNAC alone was performed before 426 operations (60 %), FNAC with FNA-Tg before 105 operations (15 %), and surgery without biopsy for 175 patients (25 %). The sensitivity, positive predictive value, and accuracy were respectively 96, 95, 100 % for FNAC, 99, 97, and 97 % for FNA-Tg, and 95, 92, and 97 % for FNAC in combination with FNA-Tg. In the subgroup of patients who had both tests performed, the sensitivity of FNA-Tg was superior to that of FNAC (95 vs 87 %; p = 0.04). The addition of FNA-Tg to FNAC increased the detection of metastatic PTC by 13 %. CONCLUSIONS: For diagnosing cervical lymph node metastases in PTC, FNA-Tg is a valuable adjunct to FNAC. Its use should be considered to avoid missing metastatic disease in patients who may benefit from lymphadenectomy.

RESUMEN

INTRODUCTION: Pheochromocytoma and paraganglioma (PPGL) are rare neoplasms; about 10% are malignant. Literature regarding possible benefit from resection is extremely limited. METHODS: A 20 year review of all patients undergoing surgery for malignant PPGL at the Mayo Clinic Rochester Campus between 1994 and June 2014 was performed. RESULTS: We identified 34 patients undergoing surgery for malignant PPGL. Median follow up was 6 and 5 years survival was 90% (median 11 years). Complete resection (R0) was achieved in 14 patients (41%). Median disease-free survival was 4.6 years for patients with R0 resection (up to 12 years). Only eight patients (23%) were disease-free on last follow up. Elevated preoperative fractionated metanephrines or catecholamines were documented in 23 patients (68%); these normalized in 13 of 23 patients (56%) postoperatively-with symptom relief in 15 of 18 preoperatively symptomatic patients (79%). Among 23 patients with hormone-producing tumors, significant reduction in number of antihypertensive medications was also noted postoperatively; 11 patients have remained off all antihypertensives, 6 required 1 medication, 1 required 2, while 5 required full blockade with phenoxybenzamine and a beta-adrenergic blocker. CONCLUSION: Surgery plays a significant role in the management of selected malignant PPGL. Resection can be effective in normalizing or significantly reducing levels of catecholamines and metanephrines, and can improve hormone-related symptoms and hypertension. Surgical resection, either complete or incomplete, is associated with durable survival despite a high rate of tumor recurrence.

RESUMEN

BACKGROUND: Clinical treatment guidelines have suggested that laparoscopic hernia repair should be the preferred approach in both men and women with bilateral or recurrent elective groin hernias. Anecdotal evidence suggests, however, that women are less likely to undergo a laparoscopic repair than men, and therefore, we aimed to delineate if these disparities persisted after controlling for patient factors and comorbidities. MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Project data were abstracted for all elective groin hernia repairs between 2005 and 2014. Univariate analysis was used to compare rates of laparoscopic surgery between men and women. Multivariable analysis was performed, controlling for patient demographics, preoperative comorbidities, and year of surgery. RESULTS: Over the 10-y period, 141,490 patients underwent elective groin hernia repair, of which 13,325 were women (9.4%). The rate of general anesthesia utilization was high in both men (81.3%) and women (77.2%) with 75.1% of open repairs being performed under general anesthesia. Overall, 20.2% of women underwent laparoscopic repair compared with 28.0% of men (P < 0.01). Women tended to be older, had a lesser body mass index, and slightly greater American Anesthesia Association (all P < 0.05). On multivariable regression, women had decreased odds of undergoing a laparoscopic approach compared with men (odds ratio: 0.70; 95% confidence interval, 0.67-0.73, P < 0.01). CONCLUSIONS: In the elective setting, women were less likely to undergo laparoscopic repair of groin hernias than men. Although we are unable to ascertain underlying causes for these gender disparities, these data suggest that there remains a disparity in the management of groin hernias in women.

RESUMEN

BACKGROUND: Outcomes of surgical trials hinge on surgeon selection and their underlying expertise. Assessment of expertise is paramount. We investigated whether surgeons' performance measured by the fundamentals of laparoscopic surgery (FLS) assessment program could predict their performance in a surgical trial. METHODS: As part of a prospective multi-institutional study of minimally invasive inguinal lymphadenectomy (MILND) for melanoma, surgical oncologists with no prior MILND experience underwent pre-trial FLS assessment. Surgeons completed MILND training, began enrolling patients, and submitted videos of each MILND case performed. Videos were scored with the global operative assessment of laparoscopic skills (GOALS) tool. Associations between baseline FLS scores and participant's trial performance metrics were assessed. RESULTS: Twelve surgeons enrolled patients; their median total baseline FLS score was 332 (range 275-380, max possible 500, passing >270). Participants enrolled 87 patients in the study (median 6 per surgeon, range 1-24), of which 72 (83%) videos were adequate for scoring. Baseline GOALS score was 17.1 (range 9.6-21.2, max possible score 30). Inter-rater reliability was excellent (ICC = 0.85). FLS scores correlated with improved GOALS scores (r = 0.57, p = 0.05) and with decreased operative time (r = -0.6, p = 0.02). No associations were found with the degree of patient recruitment (r = 0.02, p = 0.7), lymph node count (r = 0.01, p = 0.07), conversion rate (r = -0.06, p = 0.38) or major complications(r = -0.14, p = 0.6). CONCLUSIONS: FLS skill assessment of surgeons prior to their enrollment in a surgical trial is feasible. Although better FLS scores predicted improved operative performance and operative time, other trial outcome measures showed no difference. Our findings have implications for the documentation of laparoscopic expertise of surgeons in practice and may allow more appropriate selection of surgeons to participate in clinical trials.

RESUMEN

BACKGROUND: Pheochromocytoma with synchronous ipsilateral adrenal cortical adenoma (PSCA) may present with mixed clinical, biochemical, and radiological features characteristic to each neoplasm subtype. METHODS: All patients with a pathological diagnosis of pheochromocytoma were evaluated for an ipsilateral cortical adenoma from 1994 through 2015. Retrospectively extracted data included indications for adrenalectomy, diagnostic workup (biochemical and radiographic), operative characteristics, pathological findings, and postoperative complications. RESULTS: Sixteen of 413 patients (4%) undergoing adrenalectomy for pheochromocytoma had a PSCA. Median patient age was 57.7 years (IQR 50.1, 63.1); 50% were male. On imaging, 75% of the adrenal neoplasms were found incidentally and only 50% were reported to have a synchronous ipsilateral neoplasm based on imaging findings. Clinically important cortical hormone secretion was diagnosed in 38% of these patients; 25% had glucocorticoid secretory autonomy; and 13% had primary aldosteronism. CONCLUSION: Physicians should be aware that adrenal neoplasms with mixed diagnostic findings may represent PSCA. Evaluation should be performed on this co-occurrence to prevent perioperative complications from resection of an unexpected secretory cortical neoplasm.

RESUMEN

BACKGROUND: Quality-improvement efforts at our institution have identified chest tube dislodgement as a preventable complication of tube thoracostomy. Because proper fixation techniques are not well described in the literature and are seldom formally taught, techniques vary among residents. OBJECTIVE: Our aim was to develop and test a framework for teaching and assessing chest tube securement. METHODS: A repeated-measures study design was used. At baseline, 19 emergency medicine residents (program years 1-3) placed and secured a chest tube in a cadaver. After a 45-min proficiency-based teaching session using a low-cost chest tube simulator (approximate cost, $5), each resident again placed and secured a chest tube in a cadaver, followed by 3-month retention testing. All securements were evaluated by two raters using a four-point checklist and a five-point global assessment scale (GAS). The checklist addressed suture selection, tying knots down to the tube, wound approximation, and tube displacement relative to skin. RESULTS: After the initial educational intervention, median scores for the group improved significantly over baseline for the GAS (p < 0.001), checklist (p < 0.001), and amount of displacement (p = 0.01). At 3 months, GAS, checklist, and displacement scores did not differ significantly from the immediate post-test scores. Inter-rater reliability was substantial, with weighted κ values of .77 for the GAS and .70 for the checklist. CONCLUSIONS: Quality of chest tube securement by emergency medicine residents can be significantly improved with an inexpensive chest tube simulator and a brief workshop. The four-point checklist served as a reliable and effective means for teaching and assessing chest tube securement.

RESUMEN

BACKGROUND: Several approaches to minimize postoperative pain, nausea, and enhance recovery are available for patients undergoing mastectomy with immediate tissue expander (TE) reconstruction. We compared the effectiveness of intraoperative local infiltration of liposomal bupivacaine (LB) to preoperative paravertebral block (PVB). METHODS: We retrospectively reviewed patients who underwent mastectomy with immediate TE reconstruction between May 2012 and October 2014 and compared patients with preoperative ultrasound-guided PVB to those with intraoperative LB infiltration. RESULTS: Fifty-three patients (54.6 %) received LB and 44 received PVB. LB was associated with less opioid use in the recovery room (p < 0.001), fewer patients requiring antiemetics (p = 0.03), and lower day of surgery pain scores (p = 0.008). LB also was associated with longer time to first opioid use (p = 0.04). On multivariable analysis controlling for expander placement location, year of surgery, and axillary lymph node dissection (ALND), the only variable that remained statistically significant was lower opioid use in the recovery room for patients with LB (p = 0.03) and day of surgery pain scores approached significance (p = 0.05). There was no difference in the proportion of patients discharged within 36 h of surgery between the groups. Focusing on first cases of the day (where PVBs are performed in the OR) showed average time to skin incision was 15 min shorter in the LB group (p = 0.004). CONCLUSIONS: Local infiltration of LB in patients undergoing mastectomy with immediate TE reconstruction decreases narcotic requirements in the recovery room, shortens preoperative anesthesiology time, and provides similar, if not better, perioperative pain control compared with PVB.

RESUMEN

BACKGROUND: We recently sensed an increase in the frequency of groin hematoma after inguinal hernia repair (IHR) at our institution. The aim of this study was to provide a more updated assessment of the risk factors inherent to this complication. METHODS: We performed a case-control study of all adult patients (age ≥ 18 y) who developed a groin hematoma after IHR at our institution between 2003 and 2015. Univariate and multivariable analyses were performed to assess for independent predictors for groin hematoma. RESULTS: A total of 96 patients (among 6608 IHR) developed a groin hematoma, (60 were observed, 36 required intervention). The hematoma frequency increased from our previous study (1.4 % versus 0.9%, P < 0.01). Mean age was 64.6 y (range: 18-92), and 84.3% were men. There was no significant difference in the laterality, type, or technique of IHR between cases and controls. Univariate analysis (odds ratio [95% confidence interval], P) identified warfarin usage (3.5, [1.6-6.4], P < 0.01), valvular heart disease (11.6, [2.6-51.3], P < 0.01), atrial fibrillation (2.6, [1.2-5.5], P = 0.01), hypertension (2.03, [1.1-3.6], P = 0.02), recurrent hernia (3.7, [1.4-9.7], P < 0.01), and coronary artery disease (2.1, [1.0-4.4 ], P = 0.05) as significant preoperative factors. The proportion of patients on warfarin decreased since our prior report (31% versus 42%, P = 0.20). On multivariable regression, warfarin and recurrent hernia were independent predictors of hematoma development. CONCLUSIONS: Independent risk factors for the development of groin hematoma after IHR included warfarin use and recurrent hernia. Careful consideration for anticoagulation and surgical hypervigilance remains prudent in all patients undergoing IHR and especially those with recurrence.
