ABSTRACT

INTRODUCTION: This study assesses the correlation between academic grades and gross and fine motor skills in prospective surgical trainees. METHODS: Forty-seven General Surgery Residency applicants and 32 medical students with prospective surgical interests were recruited. Manual dexterity (MD) was assessed through six tasks: O'Connor Tweezer Dexterity Test and Minnesota Manual Dexterity Test; Peg Transfer Test Fundamentals of Laparoscopic Surgery (box); Ring and Rail, Thread the Ring and Suture Sponge (da Vinci Surgical Simulator). RESULTS: Medical students with higher academic scores had longer completion times for the peg transfer test (P = 0.013). Individuals who played musical instruments and perceived themselves to have "Excellent" MD and motor coordination (MC) were more likely to score higher on the Thread the Ring test (P = 0.007; P = 0.009 ,respectively). Those who perceived themselves to have "Mediocre" MD and MC performed the worst on the: O'Connor Tweezer Dexterity Test (P = 0.023). CONCLUSIONS: Preliminary data suggest that MD ability correlates with neither high United States Medical Licensing Examination scores nor high academic grades; however, previous experience playing a musical instrument and high self-ratings of MD/MC may be associated with better test performance.

ABSTRACT

BACKGROUND: This study examines the alignment of quantitative and qualitative assessment data in end-of-rotation evaluations using longitudinal cohorts of residents progressing throughout the five-year general surgery residency. METHODS: Rotation evaluation data were extracted for 171 residents who trained between July 2011 and July 2016. Data included 6069 rotation evaluations forms completed by 38 faculty members and 164 peer-residents. Qualitative comments mapped to general surgery milestones were coded for positive/negative feedback and relevance. RESULTS: Quantitative evaluation scores were significantly correlated with positive/negative feedback, r = 0.52 and relevance, r = -0.20, p < .001. Themes included feedback on leadership, teaching contribution, medical knowledge, work ethic, patient-care, and ability to work in a team-based setting. Faculty comments focused on technical and clinical abilities; comments from peers focused on professionalism and interpersonal relationships. CONCLUSIONS: We found differences in themes emphasized as residents progressed. These findings underscore improving our understanding of how faculty synthesize assessment data.

ABSTRACT

We present the case of a patient with a complicated medical history, which included stent grafting as a life-saving measure for an iatrogenic inferior vena cava (IVC) injury. For persistent sepsis secondary to stent-graft infection, the patient underwent extraction of 2 IVC stent grafts, primary repair of a duodenal-caval fistula, and repair of the IVC with an allograft vein patch. Discussion of this case sought to shed light on the intricacies involved in medical decision making in an era of advanced medical technology.

ABSTRACT

Emergency aortic surgery can be a daunting task in patients with functioning kidney and pancreas allografts because it poses the risk of allograft loss due to prolonged warm ischemia created by aortic cross-clamping. We present a case in which dual allografts, both originating from the right iliac arterial system, were protected from warm ischemia during aortic cross-clamping by creation of a temporary renofemoral shunt between the native left renal artery and right femoral artery. This simple technique maintained pulsatile allograft perfusion during aortic reconstruction for treatment of a ruptured mycotic aortic aneurysm complicated by an aortocolonic fistula.

ABSTRACT

Thoracic aortic thrombi are a well-known cause of distal embolic phenomena. There is a paucity of case reports because of the rarity of this condition, and thus clear management guidelines are lacking. The authors present a case of a mobile thoracic aortic thrombus managed by a surgical approach. This report demonstrates how intraoperative transesophageal echocardiography (TEE) proved to be critical in guiding surgical management. The utility of TEE in the diagnosis and management of aortic thrombi is also discussed. In addition, currently reported management strategies for this complex condition are reviewed.

ABSTRACT

Wound healing has evolved from gauze therapy to the use of proteomics, gene therapy, and cellular-based therapies in the short time span of 45 years. Education for health care providers has not kept pace with the logarithmic acceleration in technology development and treatment options. A patient with a non-healing wound requires a comprehensive work-up, including a focus on six primary points of interest. These points include the status of tissue perfusion, role of bacterial contamination, pressure applied to the tissue, the immune status of the host, co-morbid medical conditions including the patient's psychosocial status, and lastly, the status of the wound itself. Even after re-establishing macrovascular flow, many wounds either fail to improve or paradoxically worsen. Potential mechanisms for these unexpected findings include reperfusion injury, no-reflow, and the presence of stunned/hibernating tissue. Using the concept of mechanotransduction, the clinician can simulate normal pulsatile blood flow and re-establish adequate microvascular perfusion. Treatment regimens may include negative pressure therapy, electrical stimulation, ultrasound therapy, and other energy-based modalities.

ABSTRACT

BACKGROUND: Cigarette smoking and pulmonary emphysema are strongly associated with abdominal aortic aneurysms (AAAs), but the biologic mechanisms linking these conditions are undefined. STUDY DESIGN: To determine if exposure to cigarette smoke influences formation and growth of experimental AAAs, 129/SvEv mice were acclimated to daily cigarette smoke exposure for 2 weeks followed by transient elastase perfusion of the abdominal aorta to induce aneurysmal degeneration. Smoking was continued for intervals of either 2 or 12 weeks (8 mice per group). Nonsmoking 129/SvEv controls (n = 29) underwent elastase perfusion and followup evaluation at the same time intervals. In all animals, abdominal aortic diameter (AD) was measured to determine interval increases in AD (Delta AD), with AAAs defined as a Delta AD > 100%. RESULTS: Preperfusion and immediate postperfusion ADs were not significantly different between experimental groups. Aneurysmal dilatation was present 2 weeks after elastase perfusion in both smoking mice and nonsmoking controls, with no significant difference in final AD (mean +/- SEM: smoking, 1.23 +/- 0.11 mm versus nonsmoking, 1.22 +/- 0.05 mm). There were also no differences in the overall extent of aortic dilatation (Delta AD smoking, 136 +/- 24% versus nonsmoking, 138 +/- 10%), or the incidence of AAAs (smoking, 75% versus nonsmoking, 79%). Although all animals had developed AAAs by 12 weeks after elastase perfusion, the overall extent of aortic dilatation was 50% greater in smoking mice compared with nonsmoking controls (Delta AD smoking, 204 +/- 23% versus nonsmoking, 135 +/- 17%; p < 0.05). CONCLUSIONS: Short-term exposure to cigarette smoke did not alter initial development of experimental AAAs, but chronic smoke exposure was associated with a substantial increase in the late progression of aneurysmal dilatation. This novel combination of in vivo experimental models offers a new approach to investigate mechanisms by which cigarette smoking promotes aneurysmal degeneration.
