RESUMO

Facial fractures resulting from blunt-mechanism trauma, although common, have been infrequently evaluated in large studies that do not include confirmation of fractures based on author review of available patient radiographic studies. An 8-year review (1998-2006) of the R Adams Cowley Shock Trauma Registry was performed with institutional review board approval. Patients diagnosed with blunt-mechanism facial fractures were identified by the International Classification of Diseases, Ninth Revision (ICD-9) codes and their facial fractures confirmed by author review of computed tomographic scans. Individual fractures were classified and grouped according to the facial thirds. Intra- and interreader variability was calculated, and confirmed fracture patterns were compared to fracture patterns listed by ICD-9 codes. Concomitant injuries and demographic data were additionally evaluated. Four thousand three hundred ninety-eight patients with 8127 fractures were identified. Intra- and interreader variability was 2% and 7%, respectively. ICD-9 coding misdiagnosed 12.5% of all fractures. Eighty-two percent of patients sustained associated injuries, including basilar skull fractures (7.6%) and cervical spine fractures (6.6%). 1.1% had at least one fracture in each facial third (panfacial fracture pattern). Significant relationships were found between demographic parameters, concomitant injuries, specific fractures, and fracture patterns. Studies investigating facial fractures should report fracture patterns confirmed by author review of available radiographic imaging. Large retrospective data sets containing confirmed fractures and capable of addressing rare fracture patterns can be compiled with low inter- and intrauser variability, and are useful for generating mechanistic hypotheses suitable for evaluation in prospective series or by directed biomechanical studies.

RESUMO

OBJECTIVE: First rib resection and scalenectomy (FRRS) has been shown to improve short-term quality of life (QOL) in the treatment of neurogenic thoracic outlet syndrome (NTOS). Long-term benefits are not well studied but are believed to decrease over time. Our objective was to evaluate long-term NTOS outcomes using validated QOL instruments. METHODS: We identified 162 NTOS patients aged ≥18 years treated by FRRS from 2003 to 2010 after they had not responded to conservative management. The patients were mailed three surveys to assess QOL (Short-Form 12 [SF-12], Brief Pain Inventory [BPI], and Cervical Brachial Symptom Questionnaire [CBSQ]), with five total outcomes measures including the SF-12 Physical Component Score (PCS), SF-12 Mental Component Score (MCS), BPI severity, BPI interference, and CBSQ score. Demographic and clinical data were extracted from patient records. Each FRRS was categorized based on postoperative clinical assessment as successful, failed, or leading to recurrent symptoms. RESULTS: Survey yield was 53.7% (n = 87) with mean follow-up of 44.7 months (range, 12.4-91.9 months). There was no significant difference in QOL scores associated with long-term compared with short-term follow-up. Significantly poorer scores on all instruments were associated with comorbid chronic pain syndromes, opioid use, and unfavorable clinical assessment (P < .05). Significantly poorer scores on select instruments were associated with smoking (BPI both; P < .02), age ≥40 years (SF-12 PCS, BPI interference, CBSQ; P < .03), neck and/or shoulder disease (SF-12 both, BPI both; P < .01), postoperative injections (BPI both, CBSQ; P < .05), and complications (SF-12 PCS, CBSQ; P < .05). A positive preoperative scalene block was not significantly associated with long-term QOL scores. CONCLUSIONS: The QOL after FRRS shows no significant difference with longer follow-up. Clinical assessment reflects patient-reported outcomes and can gauge postoperative improvement. Patient factors, particularly comorbidities and opioid use, are more predictive of long-term QOL than is preoperative scalene block and should also be considered when selecting patients for surgical intervention.

RESUMO

PURPOSE: Blunt internal carotid artery injuries (BCAIs) can result from craniofacial trauma, yet the association between craniofacial fractures and BCAIs is poorly understood. MATERIALS AND METHODS: A retrospective cohort study of patients with blunt-mechanism facial fracture(s) presenting to a large trauma center was undertaken to identify facial fracture patterns predictive of BCAIs. Predictor variables included specific facial fracture patterns. Additional variables included demographic, injury mechanism, and associated injury classifications. Outcome variables included the presence or absence of BCAIs. All radiographic fracture patterns were confirmed by author review of computed tomographic imaging. BCAIs were confirmed and graded using the Biffl system. Differences in fracture patterns and demographic parameters in patients who presented with versus without concomitant BCAIs were compared, and relative risks for BCAI were calculated. Existing Eastern Association for the Surgery of Trauma Level III Blunt Cerebrovascular Injury (BCVI) screening criteria then were applied to the dataset to determine if additional fracture patterns would be useful in BCAI screening as determined by alterations in screening sensitivity and specificity. RESULTS: Seventy BCAIs were identified in 54 of 4,398 patients with facial fractures (1.2%). Bilateral fractures in each facial third, complex midface, Le Fort, and subcondylar fractures, fractures in association with the cervical spine, and basilar skull fractures were high risk for concomitant BCAI. Twenty percent of BCAIs would not have been captured by existing Eastern Association for the Surgery of Trauma Level III BCVI screening criteria. When patients meeting these screening criteria were removed from the study population, Le Fort I and subcondylar fractures were the only fracture patterns conferring increased risk for BCAI. Addition of these criteria to existing criteria improved the screening negative predictive value. CONCLUSION: Specific facial fracture patterns, including bilateral fractures in any facial third and complex midface, Le Fort I, and subcondylar fractures, confer increased risk of BCAI, especially in association with basilar skull fractures. Suspicion for BCAI in these patients may improve diagnosis and enable prompt therapeutic intervention. Addition of Le Fort I fractures to existing BCAI screening criteria improves sensitivity and may be of clinical utility in ruling out BCAIs.

RESUMO

BACKGROUND: Women undergo breast reconstruction at different time-points in their cancer care; knowing patients' preoperative quality of life (QoL) is critical in the overall care of the patient with breast cancer. Our objective was to describe presurgical QoL among women undergoing immediate, delayed, or major revision breast reconstructive surgery at our institution. METHODS: From March 2008 to February 2009, we administered preoperative BREAST-Q questionnaires to women who presented to our institution for breast reconstruction. Univariate and multivariate analyses were performed to compare patient cohorts across multiple QoL domains including body image, physical well-being, psychosocial well-being, and sexual well-being. RESULTS: Of the 231 patients who presented for preoperative consultation, 176 returned the questionnaire (response rate 76%; 117 from the immediate, 21 from the delayed, and 32 from the major revision reconstruction groups, plus 6 mixed or unknown). The three groups differed significantly (P < 0.05) across four of the six domains: body image (satisfaction with breasts), psychosocial well-being, sexual well-being, and physical well-being of the chest and upper body. The immediate reconstruction group had higher (better) scores than the delayed reconstruction group, which had higher (better) scores than the major revision group. CONCLUSION: These data suggest that women presenting for breast reconstruction at different stages of reconstruction have different baseline QoL. Such data may help us better understand patient selection, education, and expectations, and may lead to improved patient-surgeon communication.

RESUMO

PURPOSE: Programmed death-1 (PD-1), an inhibitory receptor expressed on activated T cells, may suppress antitumor immunity. This phase I study sought to determine the safety and tolerability of anti-PD-1 blockade in patients with treatment-refractory solid tumors and to preliminarily assess antitumor activity, pharmacodynamics, and immunologic correlates. PATIENTS AND METHODS: Thirty-nine patients with advanced metastatic melanoma, colorectal cancer (CRC), castrate-resistant prostate cancer, non-small-cell lung cancer (NSCLC), or renal cell carcinoma (RCC) received a single intravenous infusion of anti-PD-1 (MDX-1106) in dose-escalating six-patient cohorts at 0.3, 1, 3, or 10 mg/kg, followed by a 15-patient expansion cohort at 10 mg/kg. Patients with evidence of clinical benefit at 3 months were eligible for repeated therapy. RESULTS: Anti-PD-1 was well tolerated: one serious adverse event, inflammatory colitis, was observed in a patient with melanoma who received five doses at 1 mg/kg. One durable complete response (CRC) and two partial responses (PRs; melanoma, RCC) were seen. Two additional patients (melanoma, NSCLC) had significant lesional tumor regressions not meeting PR criteria. The serum half-life of anti-PD-1 was 12 to 20 days. However, pharmacodynamics indicated a sustained mean occupancy of > 70% of PD-1 molecules on circulating T cells ≥ 2 months following infusion, regardless of dose. In nine patients examined, tumor cell surface B7-H1 expression appeared to correlate with the likelihood of response to treatment. CONCLUSION: Blocking the PD-1 immune checkpoint with intermittent antibody dosing is well tolerated and associated with evidence of antitumor activity. Exploration of alternative dosing regimens and combinatorial therapies with vaccines, targeted therapies, and/or other checkpoint inhibitors is warranted.

RESUMO

BACKGROUND: Surgical treatment for neurogenic thoracic outlet syndrome does not always yield successful outcomes. The purpose of this study was to describe patients with unresolved, recurrent, and/or contralateral symptoms following first rib resection and scalenectomy (FRRS) and to determine therapies for improving their outcomes. METHODS: Data on 161 neurogenic thoracic outlet syndrome patients (182 FRRS procedures) were prospectively collected from 2003 to 2011 and retrospectively reviewed for evidence of unresolved, recurrent, and/or contralateral neurogenic symptoms following FRRS. Demographic and clinical characteristics, interventions, and outcomes were compared between these patients and those with a successful result. RESULTS: Twenty-three patients (24 FRRS) had unresolved symptoms at a mean of 16.1 ± 14.7 postoperative months. Compared with successes, these patients were older (mean age, 45 vs 38 years; P = .002) and active smokers (33% vs 13%; P = .031), with a longer duration of symptoms (90 vs 48 months; P = .005). They had higher rates of chronic pain syndromes (67% vs 14%; P < .001), neck and/or shoulder comorbidities (58% vs 22%; P < .001), preoperative opioid use (67% vs 31%; P = .001), and preoperative Botox injections (46% vs 20%; P = .009) with less relief (18% vs 64%; P = .014). Sixteen patients had recurrent symptoms at a mean of 12.1 ± 9.7 postoperative months. These patients had more chronic pain syndromes (38%; P = .028) and neck and/or shoulder comorbidities (50%; P = .027), with recurrence secondary to scar tissue (69%; P < .001) and reinjury (31%; P = .002). Postoperative treatments for both groups included physical therapy and local injections, where six unresolved (26%) and 13 recurrent (81%) patients achieved freedom from opioids at the end of the follow-up period. Twenty-one patients had contralateral symptoms and underwent secondary FRRS at a mean of 15.0 months (range, 7-30 months) following primary FRRS. The first operation was successful in 90% of cases. CONCLUSIONS: Patients with unresolved symptoms are older, active smokers with more comorbid pain syndromes, neck and/or shoulder disease, and a longer symptom duration. These patients face a more difficult recovery, whereas patients with recurrent symptoms are well managed with physical therapy and Botox injections. Patients with contralateral symptoms at >1 year are effectively treated with secondary FRRS. Patients must be followed closely after FRRS to determine if additional interventions are necessary to ensure successful results.

RESUMO

BACKGROUND: The relationship between extent of cervical lymphadenectomy along with the number of involved lymph nodes (LNs) removed and overall survival has not been well documented in patients with medullary thyroid carcinoma (MTC). This study investigates whether the overall number of LNs removed and the number of metastatic LNs are independent prognostic factors for overall survival. METHODS: Data from patients with MTC in the Surveillance, Epidemiology, and End Results (SEER) registry database were examined. After categorizing the study population based on the number of overall LNs examined and the number of metastatic LNs, survival estimates were compared. The total number of examined LNs and their histopathological status were analyzed for their prognostic value in estimating overall survival. RESULTS: 593 patients were included in this study. Those with all negative LNs had the best overall survival; those with LNs examined and at least one positive LN had worst overall survival (p < 0.0001). The total number of examined LNs for both groups with negative and positive LNs was not associated with improved survival outcome (p = 0.41). In node-positive patients, each additional positive LN was significantly associated with an increase in overall mortality [hazard ratio (HR) = 1.05, 95% confidence interval (CI) = 1.02-1.08]. CONCLUSIONS: Cervical LN metastases conferred an independent risk for worse survival rate in MTC. Cervical lymphadenectomy is important for staging and regional disease control, however the extent of lymph node dissection, the overall number of lymph nodes removed along with removal of an increased number of involved lymph nodes do not confer a survival advantage. Future prospective studies are needed.

RESUMO

BACKGROUND: Three-dimensional computed tomographic angiography (3D CTA) can be used preoperatively to evaluate the course and caliber of perforating blood vessels for abdominal free-flap breast reconstruction. For postmastectomy breast reconstruction, many women inquire whether the abdominal tissue volume will match that of the breast to be removed. Therefore, our goal was to estimate preoperative volume and weight of the proposed flap and compare them with the actual volume and weight to determine if diagnostic imaging can accurately identify the amount of tissue that could potentially to be harvested. METHODS: Preoperative 3D CTA was performed in 15 patients, who underwent breast reconstruction using the deep inferior epigastric artery perforator flap. Before each angiogram, stereotactic fiducials were placed on the planned flap outline. The radiologist reviewed each preoperative angiogram to estimate the volume, and thus, weight of the flap. These estimated weights were compared with the actual intraoperative weights. RESULTS: The average estimated weight was 99.7% of the actual weight. The interquartile range (25th to 75th percentile), which represents the "middle half" of the patients, was 91-109%, indicating that half of the patients had an estimated weight within 9% of the actual weight; however, there was a large range (70-133%). CONCLUSION: 3D CTA with stereotactic fiducials allows surgeons to adequately estimate abdominal flap volume before surgery, potentially giving guidance in the amount of tissue that can be harvested from a patient's lower abdomen.

RESUMO

BACKGROUND: Surgeons in training are at high risk for needlestick injuries. The reporting of such injuries is a critical step in initiating early prophylaxis or treatment. METHODS: We surveyed surgeons in training at 17 medical centers about previous needlestick injuries. Survey items inquired about whether the most recent injury was reported to an employee health service or involved a "high-risk" patient (i.e., one with a history of infection with human immunodeficiency virus, hepatitis B or hepatitis C, or injection-drug use); we also asked about the perceived cause of the injury and the surrounding circumstances. RESULTS: The overall response rate was 95%. Of 699 respondents, 582 (83%) had had a needlestick injury during training; the mean number of needlestick injuries during residency increased according to the postgraduate year (PGY): PGY-1, 1.5 injuries; PGY-2, 3.7; PGY-3, 4.1; PGY-4, 5.3; and PGY-5, 7.7. By their final year of training, 99% of residents had had a needlestick injury; for 53%, the injury had involved a high-risk patient. Of the most recent injuries, 297 of 578 (51%) were not reported to an employee health service, and 15 of 91 of those involving high-risk patients (16%) were not reported. Lack of time was the most common reason given for not reporting such injuries among 126 of 297 respondents (42%). If someone other than the respondent knew about an unreported injury, that person was most frequently the attending physician (51%) and least frequently a "significant other" (13%). CONCLUSIONS: Needlestick injuries are common among surgeons in training and are often not reported. Improved prevention and reporting strategies are needed to increase occupational safety for surgical providers.

RESUMO

OBJECTIVE: To identify risk factors associated with the development of rhegmatogenous retinal detachment (RRD) in patients enrolled in the Submacular Surgery Trials. METHODS: One thousand fifteen patients with eligible subfoveal neovascular lesions in the study eye were assigned randomly to observation or to surgery. Eyes were examined at 3 months, 6 months, 12 months, and 24 months after enrollment to assess study outcomes and adverse events, including RRDs. Adverse events also were reported at other times as clinical personnel became aware of them. Potential risk factors for the development of RRD in study eyes were evaluated using recursive partitioning and logistic regression analysis. RESULTS: Among 506 eyes assigned to surgery, RRD developed in 44 (8.7%) compared with 4 (0.8%) of 509 eyes assigned to observation. Of the 44 eyes in which RRD developed, 27 had age-related macular degeneration (AMD) and large (>3.5 MPS disk areas) hemorrhagic subfoveal neovascular lesions at baseline and represented 16.1% of all eyes with such lesions assigned to surgery. Eyes with AMD and larger hemorrhagic lesions (>16 MPS disk areas) together with relatively poor visual acuity (best-corrected visual acuity < or =20/1280) had a higher risk of RRD (odds ratio = 6.2, 95% confidence interval: 2.2-16.7) compared with those with smaller lesions and better visual acuity at baseline. CONCLUSION: Poor visual acuity and very large, predominantly hemorrhagic subfoveal neovascular AMD lesion type were the greatest risk factors for RRD after submacular surgery. Submacular surgery should be undertaken in such eyes with full awareness of the risk of RRD during subsequent follow-up.

RESUMO

BACKGROUND: The goal of this study is to report the safety and efficacy of pancreatic resection for isolated metastatic cancers from nonpancreatic primary disease. METHODS: We retrospectively identified patients from a single institution's prospectively gathered pancreaticobiliary database from 1970 to 2007 who underwent a pancreatic resection for metastatic disease. RESULTS: Forty-nine patients were identified with metastatic lesions to the pancreas. Pancreaticoduodenectomy, distal pancreatectomy, and total pancreatectomy were performed in 31, 14, and 4 patients, respectively. Pathology distribution was as follows: 21 renal cell carcinoma (RCC), 6 gallbladder cancer, 4 lung cancer, 4 ovarian cancer, 4 sarcoma, 3 melanoma, 2 colon cancer, 1 breast cancer, 1 hepatocellular carcinoma, 1 seminoma, 1 Langerhans cell histiocytosis, and 1 nonpancreatic endocrine cancer. Postoperative morbidity was 48%. There were no perioperative deaths. A statistically significant difference in survival was found between cancer types (P = .007) with median survivals ranging from 4.8 years for RCC to .9 years for melanoma. Univariate analysis demonstrated a survival disadvantage for patients with perineural (hazard ratio [HR] = 5.4, P = .004) and vascular invasion (HR = 4.4, P = .002). The most commonly resected metastatic lesion of the pancreas was RCC. Eighteen of the 23 patients with RCC had a metachronous lesion with a median length between initial operation and pancreatic resection of 9.3 years. Metachronous lesions had a survival similar to that of synchronous lesions (HR = 1.0, P = .98). Vascular invasion (HR = 2.4, P = .007) and lymph node metastases (HR = 24.1, P = .01) were associated with greater mortality. CONCLUSION: Long-term survival can be achieved in patients undergoing resection of isolated metastases to the pancreas.

RESUMO

PURPOSE: To evaluate fluorescein angiographic and visual acuity (VA) outcomes from patients enrolled in a trial of a single periocular corticosteroid injection immediately before photodynamic therapy (PDT) versus PDT alone for subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD). DESIGN: Randomized 2-center clinical trial. PARTICIPANTS: Sixty-seven subjects with AMD, subfoveal choroidal neovascularization, and best-corrected VA of 20/20 to 20/320 in the study eye who had received no more than 1 prior PDT treatment. METHODS: Subjects were randomized to receive PDT alone (no corticosteroid) or a single periocular corticosteroid injection given via the posterior superior sub-Tenon's capsule route before PDT (corticosteroid) and assessed 1, 3, and 6 months after enrollment. Best-corrected VA and intraocular pressure (IOP) measurements were taken during each examination. Color photographs and fluorescein angiograms were taken at baseline and 3 and 6 months. MAIN OUTCOME MEASURE: Presence or absence of fluorescein leakage from choroidal neovascularization 3 months after randomization. RESULTS: Between the 34 participants randomized to periocular corticosteroid and 33 to no corticosteroid, baseline features appeared balanced. Thirty-three corticosteroid participants and 30 no corticosteroid participants returned for the 3-month follow-up, at which time 56 had fluorescein leakage. Proportions of participants with leakage at 3 months for the 2 treatment groups did not statistically significantly differ; 94% of the corticosteroid group and 90% of the no corticosteroid group had fluorescein leakage at 3 months (P = 0.66). Mean VAs at 3 months after enrollment were 20/100 and 20/125 in the corticosteroid and no corticosteroid groups, respectively, decreasing on average 1.5 and 0.9 lines from baseline (P = 0.50). Adverse events included IOP > 21 mmHg in 7 corticosteroid participants (21%) and 1 (3%) no corticosteroid participant (P<0.05) and ptosis of the study eyelid in 1 (3%) corticosteroid participant. CONCLUSIONS: In contrast to previously reported uncontrolled studies and 1 controlled study, this trial did not find a reduction in the amount of fluorescein leakage 3 months after a single periocular injection of corticosteroid and PDT compared with PDT alone.

RESUMO

PURPOSE: To compare survival between patients enrolled in the Collaborative Ocular Melanoma Study (COMS) randomized trial of pre-enucleation radiation therapy (PERT) for large choroidal melanoma and eligible patients who did not enroll. METHODS: COMS clinical center personnel prospectively reported to the COMS Coordinating Center all patients with choroidal melanoma examined between November 1986 and December 1994. Deaths of enrolled patients were reported prospectively by clinical center personnel. In a COMS ancillary study, we retrospectively searched medical records of participating clinical centers, the Social Security Death Index, and the National Death Index to determine vital status of eligible patients not enrolled. Cox proportional hazards analysis was used to compare survival within 10 years of baseline reporting and before July 31, 2000, of enrolled patients versus eligible patients not enrolled. RESULTS: Clinical centers that received local institutional review board approval to participate in this ancillary study prospectively reported on 129 of 299 eligible patients not enrolled in the COMS PERT trial. The baseline characteristics of the 129 patients included in this ancillary study were similar to those of the 170 patients not included; 73 patients were reported as deceased. Previously identified prognostic covariates, i.e., age and longest tumor diameter, were confirmed to predict survival in both enrolled patients and eligible patients not enrolled; trial enrollment was not predictive. After adjusting for prognostic covariates and stratifying by clinical center, the estimated hazard ratio (enrolled vs. not-enrolled) was 1.12 (95% confidence interval: 0.83 to 1.51). CONCLUSIONS: The results of the COMS PERT trial should be generalizable to all patients with choroidal melanoma meeting the eligibility criteria for that trial. While the methods we used may not be generalizable to all clinical trials because of unique features of the COMS, other researchers may be able to use similar methods to determine the generalizability of their trial results.

RESUMO

OBJECTIVE: To determine the perceived effectiveness of surgical subspecialty training programs in teaching and assessing the 6 ACGME core competencies including research. DESIGN: Cross-sectional survey. SETTING: ACGME approved training programs in pediatric urology and colorectal surgery. PARTICIPANTS: Program Directors and recent trainees (2007-2009). RESULTS: A total of 39 program directors (60%) and 57 trainees (64%) responded. Both program directors and recent trainees reported a higher degree of training and mentorship (75%) in patient care and medical knowledge than the other core competencies (p<0.0001). Practice based learning and improvement, interpersonal and communication, and professionalism training were perceived effective to a lesser degree. Specifically, in the areas of teaching residents and medical students and team building, program directors, compared with recent trainees, perceived training to be more effective, (p = 0.004, p = 0.04). Responses to questions assessing training in systems based practice ubiquitously identified a lack of training, particularly in financial matters of running a practice. Although effective training in research was perceived as lacking by recent trainees, 81% reported mentorship in this area. According to program directors and recent trainees, the most effective method of teaching was faculty supervision and feedback. Only 50% or less of the recent trainees reported mentorship in career planning, work-life balance, and job satisfaction. CONCLUSIONS: Not all 6 core competencies and research are effectively being taught in surgery subspecialty training programs and mentorship in areas outside of patient care and research is lacking. Emphasis should be placed on faculty supervision and feedback when designing methods to better incorporate all 6 core competencies, research, and mentorship.

RESUMO

OBJECTIVES: To determine how programs are teaching and assessing procedural skills, and their perceived success. DESIGN: Cross-sectional survey. SETTING: Accreditation Council for Graduate Medical Education (ACGME) approved training programs in pediatric urology and colorectal surgery. PARTICIPANTS: Program directors and recent graduates (2007-2009). RESULTS: Thirty-nine program directors (60%), and 57 graduates (64%) responded; 89.5% of graduates and 94.9% of program directors felt training occurred successfully for the procedures that trainees were performing in their present practice. Nearly 90% of trainees and all program directors reported that there was no formal assessment of procedural competency at the beginning of training, although 66.7% of program directors reported that trainees were assessed "informally." Both program directors and trainees reported dialogue with faculty was the most frequent method used in preparing for operative procedures. Other methods (textbook/atlas, journals, web-based programs, videos) were used less frequently. Program directors with shorter tenure were more likely to use web-based and video methods; younger trainees were less likely to use textbooks/atlases. Faculty feedback on clinical decision-making and postprocedural review were perceived by both program directors and trainees as the most effective assessment methods for improving performance; however, trainees were more likely than program directors to report that postprocedure reviews were not included in their training (15.8% vs 9%, p = 0.045). Patient outcomes, written feedback from peers, and self-assessment were included in most programs, but valued less. Simulation was used in only about half the programs and was valued more highly by trainees than program directors (p = 0.011). CONCLUSIONS: Training in procedural proficiency was viewed as successful by both program directors and graduates. Dialogue with, assessment by, and feedback from faculty were frequently used and most valued; stressing the importance of the facilitator role of faculty in the education of the trainee. These findings provide guidance for the development of newer methods of teaching and assessment.

RESUMO

To improve outcomes in open heart surgery (OHS) patients, the Surgical Care Improvement Project (SCIP) requires 6 am postoperative day (POD) 1 and 2 blood glucose (BG) to be ≤200mg/dL. This study examined risk factors for SCIP noncompliance when using an insulin infusion protocol (IIP) and evaluated this SCIP metric as a surrogate for glycemic control. The authors divided 99 consecutive OHS patients, all subjected to 1 uniform IIP, into 2 groups: Group 1-SCIP compliant (n=79) and Group 2-SCIP noncompliant (n=20). They determined mean BG for the first 48 postoperative hours, percent of total time with hyperglycemia (% time BG >200mg/dL) for each group, and assessed risk of SCIP noncompliance as relates to multiple risk factors including intensity of IIP application, and switching to subcutaneous (SQ) insulin prior to 6 am on POD 2. Group 1 had lower mean BG than Group 2 and percent of total time with hyperglycemia, P<0.0001. Multivariate analysis showed diabetes, obesity in nondiabetics, and switching to SQ insulin prior to 6 am on POD 2 to be risk factors for SCIP noncompliance. The 6 am BG values on POD 1 or POD 2 each correlated with average postoperative BG, and compliance with the SCIP BG metric was associated with virtually uniform BG ≤200mg/dL. IIP application was not significantly different between groups (P=0.2). Only patients who had been switched to SQ insulin prior to 6 am POD 2 were noncompliant at 6 am on POD 2. There were hypoglycemic events (BG <70mg/dL) in 15 of 99 patients (15%), 12 of whom (80%) were in Group 1. Noncompliance with this SCIP measure occurred more frequently in patients with diabetes or, if nondiabetic, in those patients with obesity. A trend toward increased insulin assessments in the SCIP noncompliant group suggests that 1 uniform IIP for all patients may not be effective. By not requiring the reporting of hypoglycemia, SCIP may inadvertently be exposing patients to harm.

RESUMO

BACKGROUND: Surgical resection remains the only potentially curative option for patients with pancreatic adenocarcinoma (PAC). Advances in surgical technique and perioperative care have reduced perioperative mortality; however, temporal trends in perioperative morbidity and the use of adjuvant therapy on a population basis remain ill-defined. STUDY DESIGN: Using Surveillance, Epidemiology, and End Results-Medicare data, 2,461 patients with resected PAC were identified from 1991 to 2005. We examined trends in preoperative comorbidity indices, adjuvant treatment, type of pancreatic resection, and changes in morbidity and mortality during 4 time intervals (ie, 1991-1996, 1997-2000, 2001-2003, and 2003-2005). RESULTS: The majority of patients underwent pancreaticoduodenectomy (n = 1,945; 79%). There was a temporal increase in mean patient age (p < 0.05) and the number of patients with multiple preoperative comorbidities (Elixhauser comorbidities ≥3: 1991-1996, 10% vs 2003-2005, 26%; p < 0.001). Perioperative morbidity (53%) did not, however, change over time (p = 0.97) and 30-day mortality decreased by half (1991-1996: 6% vs 2003-2005: 3%; p = 0.04). Overall, 51% (n = 1,243) of patients received adjuvant therapy, with the majority receiving chemoradiation (n = 817; 33%). Among patients who received adjuvant therapy, factors associated with receipt of adjuvant chemotherapy alone relative to chemoradiation included older patient age (odds ratio = 1.75; p < 0.001) and ≥3 medical comorbidities (odds ratio = 1.57; p = 0.007). Receipt of adjuvant chemotherapy alone also increased over time (2003-2005 vs 1991-1996, odds ratio = 2.21; p < 0.001). CONCLUSIONS: Perioperative 30-day mortality associated with resection for PAC decreased by one-half from 1991 to 2005. Although patients undergoing resection for PAC were older and had more preoperative comorbidities, the incidence of perioperative complications remained stable. The relative use of adjuvant chemotherapy alone vs chemoradiation therapy for PAC has increased in the United States during the 15 years examined.

RESUMO

BACKGROUND: Precise and expedient localization of small pancreatic tumors during laparoscopic distal pancreatectomy can be difficult owing to the decreased tactile ability of laparoscopy and the homogenous appearance of the surrounding retroperitoneal fat. Precise localization of the lesion is critical to achieving adequate margins of resection while preserving as much healthy pancreas as possible. The objective in this study was to determine the effect of endoscopic tattooing of the distal pancreas on operative time. METHODS: We reviewed retrospectively 36 consecutive patients who had a laparoscopic distal pancreatectomy at our institution over a 4-year period (2006-2009). Ten patients underwent preoperative tattooing via an endoscopic transgastric technique using ultrasound guidance. The tattoo was performed using 2-4 cc of sterile purified carbon particles injected immediately proximal and anterior to the pancreatic lesion. Operative times were compared according to the presence of a tattoo. RESULTS: The endoscopically placed tattoo was easily visible upon entering the lesser sac in all 10 patients at laparoscopy. Patients with a tattoo had a shorter operative time (median, 128.5 minutes; range, 53-180) compared with patients without a tattoo (median, 180 minutes; range, 120-240; P < .01). None of the tattoo group required repeat surgery, whereas 1 patient who was not tattooed required re-resection for a lesion missed in the initial specimen. There were no complications associated with the endoscopic ultrasound-guided tattoo. CONCLUSION: Endoscopic ultrasound-guided tattooing of pancreas lesions before a laparoscopic distal pancreatectomy is safe and is associated with decreased operative time compared with nontattooed patients. This technique can allow for quick and precise localization of the lesion, allowing for optimal preservation of pancreas parenchyma and demarcating an appropriate line of resection.

RESUMO

OBJECTIVE: To determine whether women who had a delivery after bariatric surgery have lower rates of hypertensive disorders in pregnancy compared with women who had a delivery before bariatric surgery. DESIGN: Retrospective cohort study. SETTING: Claims data for 2002-6 from seven insurance plans in the United States. PARTICIPANTS: 585 women aged 16-45 who had undergone bariatric surgery, had at least one pregnancy and delivery, and had continuous insurance coverage during pregnancy plus two weeks after delivery. MAIN OUTCOME MEASURE: Hypertensive disorders in pregnancy defined with ICD-9 codes. The independent variable was the timing of delivery in relation to bariatric surgery, classified as deliveries before and after surgery. We used logistic regression to calculate odds ratios and confidence intervals for each type of hypertensive disorder in pregnancy. RESULTS: Among the 585 women who had undergone bariatric surgery and had a delivery, 269 delivered before surgery and 316 delivered after surgery. Gastric bypass was the surgery in 82% (477) of all women. Women who delivered before surgery were younger at the time of delivery (mean age 31.3 v 32.5) but had higher rates of pre-existing diabetes and gestational diabetes mellitus. Compared with women who delivered before surgery, women who delivered after surgery had substantially lower rates of pre-eclampsia and eclampsia (odds ratio 0.20, 95% confidence interval 0.09 to 0.44), chronic hypertension complicating pregnancy (0.39, 0.20 to 0.74), and gestational hypertension (0.16, 0.07 to 0.37), even after adjustment for age at delivery, multiple pregnancy (that is, twins or more), surgical procedure, pre-existing diabetes, and insurance plan. CONCLUSION: In this retrospective analysis of US women, bariatric surgery was associated with lower rates of hypertensive disorders in subsequent pregnancy.

RESUMO

BACKGROUND: Obesity is a risk factor for gestational diabetes mellitus (GDM), and bariatric surgery is an effective treatment for obesity. Our objective was to determine the association of bariatric surgery with the incidence of GDM and related complications. STUDY DESIGN: We performed a retrospective study comparing rates of GDM and related outcomes (including cesarean section, large-for-gestational-age infant, shoulder dystocia, and infection) between a group of women with a delivery before bariatric surgery and a group with a delivery after bariatric surgery. We used a private insurance claims database with information on 23,594 women who had bariatric surgery between 2002 and 2006. The dataset was searched to identify women with codes for bariatric surgery and a pregnancy resulting in a delivery at greater than 22 weeks gestation. Incidences of GDM and selected delivery complications for delivery before versus after bariatric surgery were compared using Fisher exact test and logistic regression. RESULTS: There were 346 women who had a delivery before bariatric surgery, and 354 had a delivery after bariatric surgery. Women with delivery after bariatric surgery had lower incidences of GDM (8% vs 27%, odds ratio (OR) 0.23, (95% CI 0.15 to 0.36) and cesarean section (28% vs 43%, OR0.53, 95% CI 0.39 to 0.72) than those with delivery before bariatric surgery. CONCLUSIONS: Bariatric surgery is associated with a decreased incidence of GDM and cesarean section in subsequent pregnancies. This potential effect of bariatric surgery should be considered in the management of obese women of childbearing age. Prospective studies are needed to confirm these findings.
