RESUMEN

BACKGROUND: Identification of successful general surgical residents remains a challenging endeavor for program directors with a national attrition of approximately 20% per year. The Big 5 personality traits and the Grit Scale have been extensively studied in many industries, and certain traits are associated with professional or academic success. However, their utility in surgery resident selection is unknown. METHODS: We performed a retrospective review of all categorical surgery residents (n = 34) at the University of Texas Medical Branch from 2015 to 2017. Current residents were classified into low performing (n = 12) or non-low performing (n = 22) based on residency performance and standardized test scores. Groups were assessed for differences in both conventional metrics used for selection and Big 5 and grit scores using bivariate analysis and Pearson's correlation coefficient. Personality testing was administered to recent resident applicants (n = 81). Applicants were ranked using conventional application information. We then examined the applicants' personalities and their rank position with personality characteristics of non-low-performing residents to determine if there was any correlation. RESULTS: The Big 5 personality test identified significantly higher extroversion, conscientiousness, and emotional stability scores in those residents classified as non-low performers. There was no significant difference in conventional metrics or in grit scores between non-low performers and low performers. Our final rank does not correlate well with personality traits of non-low performers. CONCLUSIONS: The Big 5 test may prove to be a useful adjunct to the traditional residency application in identifying applicants who may become successful in general surgery residency.

RESUMEN

OPINION STATEMENT: This review critically evaluates recent trials which have challenged the practice of completion lymph node dissection (CLND) for melanoma patients diagnosed with regional metastasis by positive sentinel lymph node biopsy (SLNB). Two trials in the last 2 years, DeCOG-SLT and MSLT-II, found no significant differences in melanoma-specific survival between patients, whether they received immediate CLND or observation after positive SLNB, despite decreases in nodal recurrence achieved by dissection. These trials together disfavor routine CLND in most patients after positive SLNB. However, their conclusions are limited by study populations which overall harbored a lower burden of SLN disease. Special attention needs to be given to patients who do have higher risk disease, with SLN tumor burdens exceeding 1 mm in diameter, for whom CLND may remain both prognostic and therapeutic. Current guidelines thus recommend either CLND or careful observation after positive SLNB after appropriate risk stratification of patients. While a decline in CLND is inevitable, treatment of stage III melanoma is witnessing the concurrent rise of effective adjuvant therapies. PD-1 inhibitors such as nivolumab, or combination BRAF/MEK inhibitors for V600E or K mutant melanoma, which were previously available to only trial patients with completely resected stage III disease, are now approved for use in patients with positive SLNB alone. Providers are better equipped than ever to treat clinically occult, regional metastatic disease with SLNB followed by adjuvant therapy for most patients, but should take steps to avoid undertreatment of high-risk patients who may proceed to disease relapse or progression.

RESUMEN

Introduction: Age and comorbidity are independently associated with worse outcomes for pancreatic adenocarcinoma (PDAC). However, the effect of combined age and comorbidity on PDAC outcomes has rarely been studied. This study assessed the impact of age and comorbidity (CACI) and surgical center volume on PDAC 90-day and overall survival (OS). Methods: This retrospective cohort study used the National Cancer Database from 2004 to 2016 to evaluate resected stage I/II PDAC patients. The predictor variable, CACI, combined the Charlson/Deyo comorbidity score with additional points for each decade lived ≥50 years. The outcomes were 90-day mortality and OS. Results: The cohort included 29,571 patients. Ninety-day mortality ranged from 2 % for CACI 0 to 13 % for CACI 6+ patients. There was a negligible difference (1 %) in 90-day mortality between high- and low-volume hospitals for CACI 0-2 patients; however, there was greater difference for CACI 3-5 (5 % vs. 9 %) and CACI 6+ (8 % vs. 15 %). The overall survival for CACI 0-2, 3-5, and 6+ cohorts was 24.1, 19.8, and 16.2 months, respectively. Adjusted overall survival showed a 2.7 and 3.1 month survival benefit for care at high-volume vs. low-volume hospitals for CACI 0-2 and 3-5, respectively. However, there was no OS volume benefit for CACI 6+ patients. Conclusions: Combined age and comorbidity are associated with short- and long-term survival for resected PDAC patients. A protective effect of higher-volume care was more impactful for 90-day mortality for patients with a CACI above 3. A centralization policy based on volume may have greater benefit for older, sicker patients. Key message: Combined comorbidity and age are strongly associated with 90-day mortality and overall survival for resected pancreatic cancer patients. When assessing the impact of age and comorbidity on resected pancreatic adenocarcinoma outcomes, 90-day mortality was 7 % higher (8 % vs. 15 %) for older, sicker patients treated at high-volume vs. low-volume centers but only 1 % (3 % vs. 4 %) for younger, healthier patients.

RESUMEN

BACKGROUND: Histopathologic differentiation of bacterial endocarditis from yeast-like fungal endocarditis is usually straightforward; however, an underappreciated phenomenon is the effect of antimicrobial therapy on bacterial size, shape and septa (cross-wall) formation resulting in bacterial forms that mimic yeast-like fungi. In this article we illustrate the alterations that occur in antibiotic-treated Staphylococcus aureus endocarditis and compare these changes to histopathologic findings in unaltered S. aureus and Histoplasma endocarditis, respectively. METHODS: Resected valves from three cases of endocarditis were compared based on the type ofinflammatory reaction, organism morphology and culture results. Case 1 was S. aureus endocarditis initially misclassified as Histoplasma due to its atypical morphologic and histopathologic features. The two cases included for comparison were an S. aureus endocarditis with more classic features and an Histoplasma capsulatum endocarditis. Hematoxylin and eosin (H&E), Gram, periodic acid Schiff (PAS), Gomori-Grocott methenamine silver stains (GMS), and culture results were compared in all cases. Molecular and immunohistochemistry tests were used for confirmation of first case. High power oil-immersion was used to visualize organisms' characteristics in all three cases. RESULTS: Case 1 and Case 3 (Histoplasma-infected valves) had fibrinous exudates with scattered macrophages. The microorganisms observed in the first case of methicillin-sensitive S. aureus (MSSA) were ∼ 2-3 µm by GMS stain and had prominent septations. Histoplasma yeast were round to oval, ∼ 3-4 µm in size and demonstrated budding. S. aureus without alterations were round, ∼ 1 µm in size, and lacked prominent septations. Necrotizing purulent inflammation was present in the unaltered case of MSSA. The MSSA case with alterations from antibiotic treatment did not stain well with the Gram stain and organisms were best visualized with the PAS and GMS stains. CONCLUSIONS: Antibiotic therapy for bacterial endocarditis can alter the inflammatory reaction to infection, bacterial size, septa formation, and staining characteristics. Knowledge of these therapy-related effects and use of high-power magnification helps to avoid misclassification as yeast-like fungi.

RESUMEN

In-transit melanoma represents a distinct disease pattern of heterogeneous superficial tumors. Many treatments have been developed specifically for this type of disease, including regional chemotherapy and a variety of directly injectable agents. Novel strategies include the intralesional delivery of oncolytic viruses and immunocytokines. The combination of intralesional or regional chemotherapy with systemic immune checkpoint inhibitors also is a promising approach. In the current review, we examine the general management of the workup of patients with in-transit disease, the range of available therapies, and recommendations for specific therapies for an individual patient.

RESUMEN

INTRODUCTION: Resident satisfaction is a key performance metric for surgery programs; we studied factors influencing resident satisfaction in operative cases, and the concordance of faculty and resident perceptions on these factors. METHODS: Resident and faculty were separately queried on satisfaction immediately following operative cases. Statistical significance of the associations between resident and faculty satisfaction and case-related factors were tested by Chi-square or Fisher's exact test. RESULTS: Residents and faculty were very satisfied in 56/87 (64%) and 36/87 (41%) of cases respectively. Resident satisfaction was associated with their perceived role as surgeon (p < 0.04), performing >50% of the case (p < 0.01), autonomy (p < 0.03), and PGY year 4-5(p < 0.02). Faculty taking over the case was associated with both resident and faculty dissatisfaction. Faculty satisfaction was associated with resident preparation (p < 0.01), faculty perception of resident autonomy (p < 0.01), and faculty familiarity with resident's skills (p < 0.01). CONCLUSIONS: Resident and faculty satisfaction are associated with the resident's competent performance of the case, suggesting interventions to optimize resident preparation for a case or faculty's ability to facilitate resident autonomy will improve satisfaction with OR experience.

RESUMEN

BACKGROUND: The ACGME case log is one of the primary metrics used to determine resident competency; it is unclear if this is an accurate reflection of the residents' role and participation. METHODS: Residents and faculty were independently administered 16-question surveys following each case over a three-week period. The main outcome was agreement between resident and faculty on resident role and percent of the case performed by the resident. RESULTS: Matched responses were collected for 87 cases. Agreement on percent performed occurred in 61% of cases, on role in 63%, and on both in 47%. Disagreement was more often due to resident perception they performed more of the case. Faculty with <10 years experience were more likely to have disagreement compared to faculty with ≥10 years (p = 0.009). CONCLUSIONS: There was a high degree of disagreement between faculty and residents regarding percent of the case performed and role. Accurate understanding of participation and competency is vital for accrediting institutions and for resident self-assessment meriting further study of the causes for this disagreement to improve training and evaluation.

RESUMEN

Most patients with pancreatic cancer will present with metastatic or locally advanced disease. Unfortunately, most patients with localized disease will experience recurrence even after multimodality therapy. As such, pancreatic cancer patients arrive at a common endpoint where decisions pertaining to palliative care come to the forefront. This article summarizes surgical, endoscopic, and other palliative techniques for relief of obstructive jaundice, relief of duodenal or gastric outlet obstruction, and relief of pain due to invasion of the celiac plexus. It also introduces the utility of the palliative care triangle in clarifying a patient's and family's goals to guide decision making.

RESUMEN

BACKGROUND: Because outpatient surgery is being increasingly scrutinized in the lay press, it is important that dermatologists and dermatologic surgeons accurately characterize the safety of office-based surgery. Although there is abundant anecdotal evidence to support the inherent safety of dermatologic surgery, there are few data that support the safety of Mohs micrographic surgery (MMS) as performed by appropriately trained dermatologic surgeons in outpatient settings. DESIGN: All patients presenting for MMS micrographic surgery during the calendar year 2000 were prospectively enrolled in this study designed to evaluate the incidence of multiple complications associated with scalpel-based cutaneous surgery (postoperative hemorrhage, hematoma formation, wound infection, wound dehiscence, and flap/graft necrosis). SETTING: An academic MMS practice. PATIENTS: A total of ,1052 patients (1,358 MMS cases) were prospectively enrolled. Complete follow-up information was available for 1,343 cases (98.9%). RESULTS: Complications associated with MMS were very infrequent, with an overall complication incidence of 1.64% (22/1,343). Most surgical complications involved difficulties with hemostasis. No complications were significant enough to involve the assistance of another specialist or to require the hospitalization of the patient. CONCLUSIONS: Mohs micrographic surgery is a very safe outpatient procedure when performed by appropriately trained physicians. The types of complications seen in our patients were identical to those seen in hospitalized patients described in previous studies. Our complication rates were equal to or lower than the published complication rates from specialists in other surgical disciplines.

RESUMEN

Since the inception of Mohs micrographic surgery in the 1930s, this technique has proved its utility in the treatment of cutaneous tumors. This review describes the technique of Mohs micrographic surgery and the various indications for which it is used. We discuss the use of Mohs micrographic surgery for the following cutaneous tumors: basal cell carcinoma, squamous cell carcinoma, melanoma in situ, dermatofibrosarcoma protuberans, Merkel cell carcinoma, microcystic adnexal carcinoma, atypical fibroxanthoma, and sebaceous carcinoma. Mohs micrographic surgery is cost effective in the U.S. health care system because billing for the surgeon-pathologist and laboratory processing is bundled together. However, Mohs micrographic surgery may be more expensive in European systems because the Mohs technique surgeon, pathologist, and laboratory fees may be billed separately.
