RESUMO
OBJECTIVE: To review the current state of research training during surgical residency and make recommendations commensurate with current surgical training and academic environment. SUMMARY BACKGROUND DATA: Research training has been a mainstay of academic surgical programs, yet the scientific disciplines have evolved significantly from the traditional years of bench research. It is time to reconsider how research training should prepare surgeons for future academic practice and ensure the foundational knowledge of research evidence. METHODS: As part of the Blue Ribbon Committee II, a research subcommittee was tasked to make recommendations on research training during surgical residency. Our eight-member panel brought diverse perspectives of the roles and goals of research training. We also sought input from a convenience sample of current and recent surgical residents on impact of research training during their residency. RESULTS: We identified a lack of a common framework and foundational research training for all surgical residents. Participation in dedicated years of scholarly activity helped trainees meet several professional and personal goals. The lack of an integrated, dedicated research track may dissuade some medical school graduates from pursuing surgery. CONCLUSIONS: We recommend incorporating a minimum standard for all trainees and flexibility in dedicated scholarly training to meet the needs of future academic surgeons.
RESUMO
BACKGROUND: Peer support programs have evolved to train physicians to provide outreach and emotional first aid to their colleagues when they experience the inevitable challenge of a serious adverse event, whether or not it is related to a medical error. Most pediatric surgeons have experienced the trauma of a medical error, yet, in a survey of APSA membership, almost half said that no one reached out to them, and few were satisfied with their institution's response to the error. Thus, the APSA Wellness Committee developed an APSA-based peer support program to meet this need. METHODS: Peer supporters were nominated by fellow APSA members, and the group was vetted to ensure diversity in demographics, practice setting, and seniority. Formal virtual training was conducted before the program went live in 2020. Trained supporters were surveyed 6 months after the program launched to evaluate their experiences with providing peer support. RESULTS: 15 referrals were made in the first year, 60 % of which were self-initiated. Most referrals were for distress related to adverse events or toxic work environments (33 % each). While only about 25 % of trained supporters had provided formal support through the APSA program, more than 80 % reported using the skills to support colleagues and trainees within their own institutions. CONCLUSION: Our experience in the first year of the APSA peer support program demonstrates the feasibility of building and maintaining a national program to provide emotional first aid by a professional society to expand the safety net for surgeons who are suffering.

Biliary obstruction results in a well-characterized cholestatic inflammatory and fibrogenic process; however, the mechanisms and potential for liver repair remain unclear. We previously demonstrated that Kupffer cell depletion reduces polymorphonuclear cell (neutrophil) (PMN) and matrix metalloproteinase (MMP)8 levels in repairing liver. We therefore hypothesized that PMN-dependent MMP activity is essential for successful repair. Male Sprague-Dawley rats received reversible biliary obstruction for 7 days, and the rat PMN-specific antibody RP3 was administered 2 days before biliary decompression (repair) and continued daily until necropsy, when liver underwent morphometric analysis, immunohistochemistry, quantitative RT-PCR, and in situ zymography. We found that RP3 treatment did not reduce Kupffer cell or monocyte number but significantly reduced PMN number at the time of decompression and 2 days after repair. RP3 treatment also blocked resorption of type I collagen. In addition, biliary obstruction resulted in increased expression of MMP3, MMP8, and tissue inhibitor of metalloproteinase 1. Two days after biliary decompression, both MMP3 and tissue inhibitor of metalloproteinase 1 expression declined toward sham levels, whereas MMP8 expression remained elevated and was identified in bile duct epithelial cells by immunohistochemistry. PMN depletion did not alter the hepatic expression of these genes. Conversely, collagen-based in situ zymography demonstrated markedly diminished collagenase activity following PMN depletion. We conclude that PMNs are essential for collagenase activity and collagen resorption during liver repair, and speculate that PMN-derived MMP8 or PMN-mediated activation of intrinsic hepatic MMPs are responsible for successful liver repair.

Background. Robotic surgical systems are expensive to own and operate, and the purchase of such technology is an important decision for hospital administrators. Most prior literature focuses on the comparison of clinical outcomes between robotic surgery and other laparoscopic or open surgery. There is a knowledge gap about what drives hospitals' decisions to purchase robotic systems. Objective. To identify factors associated with a hospital's acquisition of advanced surgical systems. Method. We used 2002 to 2011 data from the State of California Office of Statewide Health Planning and Development to examine robotic surgical system purchase decisions of 476 hospitals. We used a probit estimation allowing heteroscedasticity in the error term including a set of two equations: one binary response equation and one heteroscedasticity equation. Results. During the study timeframe, there were 78 robotic surgical systems purchased by hospitals in the sample. Controlling for hospital characteristics such as number of available beds, teaching status, nonprofit status, and patient mix, the probit estimation showed that market-level directly relevant surgery volume in the previous year (excluding the hospital's own volume) had the largest impact. More specifically, hospitals in high volume (>50,000 surgeries v. 0) markets were 12 percentage points more likely to purchase robotic systems. We also found that hospitals in less competitive markets (i.e., Herfindahl index above 2500) were 2 percentage points more likely to purchase robotic systems. Limitations. This study has limitations common to observational database studies. Certain characteristics such as cultural factors cannot be accurately quantified. Conclusions. Our findings imply that potential market demand is a strong driver for hospital purchase of robotic surgical systems. Market competition does not significantly increase the adoption of new expensive surgical technologies.
RESUMO
OBJECTIVE: To evaluate the outcome of twin-to-twin transfusion syndrome (TTTS) treated using a combination of endoscopic fetal surgery-specific techniques and surgical restraint. SUMMARY BACKGROUND DATA: TTTS is a condition of identical twins that, if progressive and left untreated, leads to 100% mortality. The best treatment option is obliteration of the intertwin placental anastomoses, but fetal surgery carries significant maternal and fetal risks. Even if successful, percutaneous endoscopic laser ablation of placental vessels (LASER) causes premature rupture of membranes (PROM) in 10% to 20% of pregnancies. Patient selection is particularly critical because the progression of the disease is unpredictable. This has prompted many to intervene early, yielding survival rates of >=1 twin of 75% to 80%. METHODS: We developed a minimally invasive approach to fetal surgery, a unique membrane sealing technique and a conservative algorithm that reserves intervention for severe TTTS. Pregnancies with TTTS (stages I-IV) managed in the last 8 years were reviewed. LASER was offered in stage III/IV only. RESULTS: Ninety-eight cases of TTTS were managed in a pediatric surgery/maternal-fetal medicine collaborative Fetal Treatment Program-39 were observed (40%) and 59 underwent LASER (60%). Survival of >= twin was seen in 82.7%, and overall survival was 69.4%. These survival rates are similar to, or better than, other comparable series with similar stage distribution (low:high stage ratio 1:1) in which all patients underwent LASER. PROM rate was 4%. CONCLUSIONS: Reserving LASER treatment for severe TTTS results in outcomes similar to, or better than, LASER for all stages. Applying fetal surgery-specific endoscopic techniques, including port-site sealing, reduces postoperative complications.

BACKGROUND: Biliary atresia is characterized by extrahepatic bile duct obliteration along with persistent intrahepatic portal inflammation. Steroids are standard in the treatment of cholangitis following the Kasai portoenterostomy, and were advocated for continued suppression of the ongoing immunologic attack against intrahepatic ducts. Recent reports, however, have failed to demonstrate an improved patient outcome or difference in the need for liver transplant in postoperative patients treated with a variety of steroid regimes compared with historic controls. In the wake of progressive liver disease despite biliary decompression, steroids are hypothesized to suppress inflammation and promote bile flow without any supporting data regarding their effect on the emerging cellular and molecular mechanisms of liver repair. We have previously shown in a reversible model of cholestatic injury that repair is mediated by macrophages, neutrophils, and specific matrix metalloproteinase activity (MMP8); we questioned whether steroids would alter these intrinsic mechanisms. METHODS: Rats underwent biliary ductal suspension for 7 d, followed by decompression. Rats were treated with IV dexamethasone or saline at the time of decompression. Liver tissue obtained at the time of decompression or after 2 d of repair was processed for morphometric analysis, immunohistochemistry, and quantitative RT-PCR. RESULTS: There was a dramatic effect of dexamethasone on the inflammatory component with the initiation of repair. Immunohistochemistry revealed a reduction of both ED1+ hepatic macrophages and ED2+Kupffer cells in repair compared with saline controls. Dexamethasone treatment also reduced infiltrating neutrophils by day 2. TNF-alpha expression, increased during injury in both saline and dexamethasone groups, was markedly reduced by dexamethasone during repair (day 2) whereas IL-6, IL-10, and CINC-1 remained unchanged compared with saline controls. Dexamethasone reduced both MMP8 and TIMP1 expression by day 2, whereas MMP9, 13, and 14 were unchanged compared with sham controls. Despite substantial cellular and molecular changes during repair, collagen resorption was the same in both groups CONCLUSION: Dexamethasone has clear effects on both the hepatic macrophage populations and infiltrating neutrophils following biliary decompression. Altered MMP and TIMP gene expression might suggest that steroids have the potential to modify matrix metabolism during repair. Nevertheless, successful resorption of collagen fibrosis proceeded presumably through other MMP activating mechanisms. We conclude that steroids do not impede the rapid intrinsic repair mechanisms of matrix degradation required for successful repair.

BACKGROUND: The effects of immaturity and hypoplasia of the premature lung can be affected by proinflammatory stimuli in late gestation or the postnatal period from acute lung injury secondary to intensive ventilatory management or the metabolic consequences of surgery. These stimuli alter alveolarization and contribute to bronchopulmonary dysplasia. While prior research has focused primarily on late gestational effects of inflammation on alveolar development, we sought to study whether early gestational exposure to endotoxin affects branching morphogenesis, during the critical pseudoglandular stage of lung development. METHOD: Gestational day 15 (E15) fetal rat lung explants (term = 22 d) were treated with either 200 ng/mL or 2 microg/mL lipopolysaccharides (LPS) with controls and examined daily by phase microscopy. After 5 d, explants were fixed in 4% formaldehyde, paraffin embedded, and sectioned at 5 mum in the coronal plane. Immunohistochemical analysis was performed with platelet endothelial cell adhesion molecule (PECAM) to define endothelial cells, vascular endothelial growth factor (VEGF) to examine endothelial mitogenesis, and COX-2 antibodies as a marker for prostaglandin synthesis. Real-time PCR examined inducible nitric oxide synthase (iNOS), FGF9, FGF10, and FGFr2 gene expression. Air space fraction and airway epithelium were analyzed with Image J software. RESULTS: Phase contrast microscopy and hematoxylin-eosin histology revealed progressive, dose-related changes in air sac contraction and interstitial thickening. Compared with control E15 explants, day 5 explants incubated with high dose LPS demonstrated thickened and shrunken airway sacs with stunted branching and increased matrix deposition in interstitial areas. By immunohistochemical staining, COX-2 was quantitatively increased after high dose LPS exposure, while PECAM was reduced. VEGF expression was unaltered. LPS increased iNOS, but decreased FGF9, FGF10, and FGFr2 gene expression. CONCLUSIONS: These data support evidence for an inflammatory effect of LPS on the early phase of lung development in the fetal rat, affecting branching morphogenesis during the pseudoglandular phase. Fetal endothelial cells are clearly affected, while COX-2 elevation suggests activation of an as yet undefined fetal pulmonary inflammatory cascade. We speculate that proinflammatory stimuli may ultimately lead to abnormal pulmonary development via fibroblastic growth factor (FGF)-directed mechanisms that affect epithelial-mesenchymal interaction and differentiation at a much earlier gestational age than was previously recognized.

Head and neck masses are a common clinical concern in infants, children, and adolescents. The differential diagnosis for a head or neck mass includes congenital, inflammatory, and neoplastic lesions. An orderly and thorough examination of the head and neck with an appropriate directed workup will facilitate the diagnosis. The most common entities occur repeatedly within the various age groups and can be differentiated with a clear understanding of embryology and anatomy of the region, and an understanding of the natural history of a specific lesion. Congenital lesions most commonly found in the pediatric population include the thyroglossal duct cyst and the branchial cleft and arch anomalies. The inflammatory masses are secondary to local or systemic infections. The most common etiology for cervical adenopathy in children is reactive lymphadenopathy following a viral or bacterial illness. Persistent adenopathy raises more concerns, especially enlarged lymph nodes within the posterior triangle or supraclavicular space, nodes that are painless, firm, and not mobile, or a single dominant node that persists for more than 6 weeks should all heighten concern for malignancy. In this review, we discuss the current principles of surgical management of the most common head and neck masses that present to pediatricians and pediatric surgeons.

There is a significant amount of interest among general surgery residency training programs in North America to have a rotation in an underserved part of the world. Usually, these global surgery rotations for the general surgery residents have been extended in duration to allow for emersion and continuity. There is similar interest among a few of the pediatric surgery training programs to initiate short, one month rotations in the global surgery arena as part of the two year pediatric surgery residency training.

PURPOSE: Nonoperative treatment of acute appendicitis appears to be feasible in adults. It is unclear whether the same is true for children. METHODS: Children 5-18 years with <48 h symptoms of acute appendicitis were offered nonoperative treatment: 2 doses of piperacillin IV, then ampicillin/clavulanate ×1 week. Treatment failure (worsening on therapy) and recurrence (after completion of therapy) were noted. Patients who declined enrollment were asked to participate as controls. Cost-utility analysis was performed using Pediatric Quality of Life Scale (PedsQL®) to calculate quality-adjusted life month (QALM) for study and control patients. RESULTS: Twenty-four patients agreed to undergo nonoperative management, and 50 acted as controls. At a mean follow-up of 14 months, three of the 24 failed on therapy, and 2/21 returned with recurrent appendicitis at 43 and 52 days, respectively. Two patients elected to undergo an interval appendectomy despite absence of symptoms. Appendectomy-free rate at one year was therefore 71% (C.I. 50-87%). No patient developed perforation or other complications. Cost-utility analysis shows a 0.007-0.03 QALM increase and a $1359 savings from $4130 to $2771 per nonoperatively treated patient. CONCLUSION: Despite occasional late recurrences, antibiotic-only treatment of early appendicitis in children is feasible, safe, cost-effective and is experienced more favorably by patients and parents.

IMPORTANCE: The number of practicing pediatric surgeons has increased rapidly in the past 4 decades, without a significant increase in the incidence of rare diseases specific to the field. Maintenance of competency in the index procedures for these rare diseases is essential to the future of the profession. OBJECTIVE: To describe the demographic characteristics and operative experiences of practicing pediatric surgeons using Pediatric Surgery Board recertification case log data. DESIGN, SETTING, AND PARTICIPANTS: We performed a retrospective review of 5 years of pediatric surgery certification renewal applications submitted to the Pediatric Surgery Board between 2009 and 2013. A surgeon's location was defined by population as urban, large rural, small rural, or isolated. Case log data were examined to determine case volume by category and type of procedures. Surgeons were categorized according to recertification at 10, 20, or 30 years. MAIN OUTCOME AND MEASURE: Number of index cases during the preceding year. RESULTS: Of 308 recertifying pediatric surgeons, 249 (80.8%) were men, and 143 (46.4%) were 46 to 55 years of age. Most of the pediatric surgeons (304 of 308 [98.7%]) practiced in urban areas (ie, with a population >50â¯000 people). All recertifying applicants were clinically active. An appendectomy was the most commonly performed procedure (with a mean [SD] number of 49.3 [35.0] procedures per year), nonoperative trauma management came in second (with 20.0 [33.0] procedures per year), and inguinal hernia repair for children younger than 6 months of age came in third (with 14.7 [13.8] procedures per year). In 6 of 10 "rare" pediatric surgery cases, the mean number of procedures was less than 2. Of 308 surgeons, 193 (62.7%) had performed a neuroblastoma resection, 170 (55.2%) a kidney tumor resection, and 123 (39.9%) an operation to treat biliary atresia or choledochal cyst in the preceding year. Laparoscopy was more frequently performed in the 10-year recertification group for Nissen fundoplication, appendectomy, splenectomy, gastrostomy/jejunostomy, orchidopexy, and cholecystectomy (P < .05) but not lung resection (P = .70). It was more frequently used by surgeons recertifying in the 10-year group (used in 11â¯375 of 14â¯456 procedures [78.7%]) than by surgeons recertifying in the 20-year (used in 6214 of 8712 procedures [71.3%]) or 30-year group (used in 2022 of 3805 procedures [53.1%]). CONCLUSIONS AND RELEVANCE: Practicing pediatric surgeons receive limited exposure to index cases after training. With regard to maintaining competency in an era in which health care outcomes have become increasingly important, these results are concerning.

BACKGROUND: Although timely surgical treatment of liver disease can interrupt inflammation and reduce fibrosis, the mechanisms of repair are unknown. We questioned whether these mechanisms of repair include changes in the inflammatory infiltrate and associated biological activity of matrix metalloproteinases (MMPs) 8 and 2. METHODS: Rats (n >or= 3) underwent biliary ductal suspension for 7 days followed by decompression. Livers were collected after 7 days of obstruction (d0) and after 2, 5, and 7 days of repair (d2, d5, d7, respectively), and assessed morphometrically for collagen, polymorphonuclear cells (PMNs), Kupffer cells (KCs), and inflammatory mononuclear phagocytes (MNPs). In situ zymography was performed by using fluorogenic substrates for MMP-8 and MMP-2 to spatially localize enzymatic activity. RESULTS: Cholestatic injury resulted in significantly elevated (P Assuntos

RESUMO
HYPOTHESIS: Endoscopic retrograde cholangiopancreatography (ERCP) is frequently used preoperatively in adult patients with suspected choledocholithiasis. Cholelithiasis occurs much less often in children, and the indications for ERCP are not established. We hypothesized that the natural history of choledocholithiasis in children is spontaneous passage of stones through the papilla and that these children can be managed without routine preoperative ERCP. DESIGN: Retrospective analysis of patients treated over a 10-year period. SETTING: Tertiary care children's hospital. PATIENTS: All patients with cholecystectomy for biliary disease. INTERVENTIONS: Cholecystectomy; intraoperative cholangiography for suspected choledocholithiasis: hyperbilirubinemia, gallstone pancreatitis, and ultrasonographic evidence of common bile duct dilation or common bile duct stones; and postoperative ERCP for symptomatic choledocholithiasis: pain and jaundice. MAIN OUTCOME MEASURES: Incidence and complications of choledocholithiasis and frequency of ERCP. RESULTS: One hundred patients (63 females) were studied. Indications included acute cholecystitis (10%), chronic cholecystitis (59%), gallstone pancreatitis (26%), and choledocholithiasis (5%). An intraoperative cholangiography was performed in 45 patients, and common bile duct stones were identified in 13. Expectant management of asymptomatic common bile duct stones was associated with sonographic resolution within 1 week. One patient with intraoperative cholangiography-proven choledocholithiasis required ERCP for symptoms 24 hours after operation. One additional patient, who did not undergo intraoperative cholangiography, developed symptomatic choledocholithiasis and required ERCP. There were no choledocholithiasis- or ERCP-related complications. CONCLUSIONS: This study suggests that choledocholithiasis occurs frequently in children and that spontaneous passage of common bile duct stones is common. This could explain the relatively high incidence of gallstone pancreatitis. Conservative management of choledocholithiasis is successful in the majority of patients. Routine preoperative or postoperative ERCP is usually not indicated.

BACKGROUND: Neonates receiving parenteral nutrition (PN) are at risk for PN-associated cholestasis (PNAC); however, no preventive factors for PNAC have been clearly identified. Despite reports suggesting that taurine may prevent PNAC in neonates, such an effect of taurine has not yet been definitively demonstrated. We determined whether taurine supplementation reduces the incidence of PNAC in premature or critically ill neonates. METHODS: This study was part of a prospective, randomized, multi-institutional trial designed to assess cholecystokinin vs placebo as a potential preventive therapy of PNAC. Taurine supplementation of PN varied between institutions. The presence or absence of taurine in PN was analyzed by multivariate analysis, with a primary outcome measure of serum conjugated bilirubin (CB) as a measure of PNAC. RESULTS: Taurine reduced PNAC in premature infants (estimated maximum CB [95% confidence interval] 0.50 mg/dL [-0.17 to 1.18] for those receiving taurine, vs 3.45 mg/dL [1.79-5.11] for neonates not receiving taurine, approaching significance, p = .07). Taurine significantly reduced PNAC in infants with necrotizing enterocolitis (NEC; estimated maximum CB 4.04 mg/dL [2.85-5.23], NEC infants receiving taurine, vs 8.29 mg/dL [5.61-10.96], NEC infants not receiving taurine, p < .01). There were too few neonates with surgical anomalies to evaluate the effect of taurine in this group. CONCLUSIONS: Within specific subgroups of neonatal patients, taurine supplementation does offer a very significant degree of protection against PNAC. Patients with NEC or severe prematurity are most likely to benefit substantially from taurine supplementation.

PURPOSE: Increasing numbers of programs participating in the pediatric surgery match has resulted in economic and logistical issues for candidates, General Surgery residencies, and Pediatric Surgery training programs (PSTP). We sought to determine the ideal number of interviews conducted by programs based on resultant rank order lists (ROL) of matched candidates. METHODS: PSTPs received 4 online surveys regarding interview practices (2011-2012, 2014), and matched candidate ROL (2008-2010, 2012, 2014). Program directors (PD) also provided estimates regarding minimum candidate interview numbers necessary for an effective match (2011-2012, 2014). Kruskal-Wallis equality-of-populations rank tests compared ROL and interview numbers conducted. Quartile regression predicted ROL based on the interview numbers. Wilcoxon signed rank-sum tests compared the interview numbers to the minimal interview number using a matched pair. p Values<0.05 were significant. RESULTS: Survey response rates ranged from 85-100%. Median ROL of matched candidates (2-3.5) did not differ between programs (p=0.09) and the lowest matched ROL for any year was 10-12. Interview numbers did not affect the final candidate ROL (p=0.22). While PDs thought the minimum median interview number should be 20, the number actually conducted was significantly higher (p<0.001). CONCLUSION: These data suggest that PSTPs interview excessive numbers of candidates. Programs and applicants should evaluate mechanisms to reduce interviews to limit costs and effort associated with the match.

OBJECTIVE: To test the hypothesis that term gestation offers the best outcome. The relationship between gestational age and the extent of bowel injury in fetuses with gastroschisis is a matter of debate. Early delivery and cesarean delivery have been recommended to limit intestinal damage, but their benefits are unclear. METHODS: Data on all patients with gastroschisis seen at our institution from 1991 through 2001 were included. Patients were compared based on gestational age: less than 35 weeks, 35-37 weeks, and term (more than 37 weeks) with regard to age at definitive closure, age at first and full feedings, and hospital stay. Statistical significance (P <.05) was determined by analysis of variance and chi(2) analysis. RESULTS: Of the 57 patients, 19.3%, 43.8%, and 36.9% were born at less than 35 weeks, 35-37 weeks, and more than 37 weeks, respectively. Age at definitive closure was significantly higher at 35-37 weeks (5.9 +/- 4.6 days) than at more than 37 weeks (1.5 +/- 2.3 days) and less than 35 weeks (2.6 +/- 2.5 days) (P <.05). A prosthetic pouch (silo) was used more often at 35-37 weeks than at more than 37 weeks or less than 35 weeks (P =.03, chi(2)). Age at first (P =.04) and full feedings (P <.01) and length of hospitalization (P <.01) were all significantly higher at 35-37 weeks than at more than 37 weeks. CONCLUSION: Based on a homogeneous cohort of patients in whom gastroschisis was diagnosed antenatally, term delivery results in earlier closure of the defect and shorter time to full feedings. The benefit of early delivery postulated by others cannot be substantiated.

A 19-yr-old adolescent, who was hospitalized because of pelvic inflammatory disease (PID) due to Chlamydia trachomatis, developed bile-stained emesis. A mild amount of free fluid in the pelvis was found on abdominal ultrasound but there was no sonographic evidence of a pelvic mass or of a tubo-ovarian abscess. Plain radiography and computer tomography (with contrast) of the abdomen revealed a high-grade partial small bowel obstruction. Conservative treatment, which included intravenous fluids and antibiotics together with continuous bowel decompression via nasogastric tube, led to resolution of the small bowel obstruction within 2 days and to resumption of oral feeding within 4 days of treatment. Follow-up for 6 months after this episode was uneventful. The present case calls for inclusion of plain radiography of the abdomen in the evaluation of PID associated with emesis. It also suggests that, in a clinically stable patient diagnosed with small bowel obstruction associated with PID, conservative treatment could be attempted before any operative intervention is considered.

BACKGROUND: Despite increased utilization of laboratory, radiologic imaging, and scoring systems, negative appendectomy (NA) rates in children remain above 3% nationwide. We reviewed the clinical data of patients undergoing appendectomy to further reduce our NA rate. METHODS: A retrospective review was conducted of all appendectomies performed for suspected appendicitis at a tertiary children's hospital during a 42-month period. Preoperative clinical, laboratory, and radiographic data were collected. Variables absent or normal in more than half of NAs were further analyzed. Receiver operating characteristic curves were constructed for continuous variables by using appropriate cutoff points to determine sensitivity and false-positive rates. The results were validated by analyzing the 12 months immediately after the establishment of these rules. RESULTS: Of 847 appendectomies performed, 22 (2.6%) had a pathologically normal appendix. The only variables found to be normal in more than half of NAs were white blood cell (WBC) count (89%) and neutrophil count (79%). A receiver operating characteristic curve indicates that using WBC cutoffs of 9000 and 8000 per µL yielded sensitivities of 92% and 95%, respectively, and reduction in NA rates by 77% and 36%, respectively. Results observed in the subsequent 12 months confirmed these expected sensitivities and specificities. CONCLUSIONS: Absence of an elevated WBC count is a risk factor for NA. Withholding appendectomy for WBC counts <9000 and 8000 per µL reduces the NA rate to 0.6% and 1.2%, respectively. Missed true appendicitis in patients with normal WBC counts can be mitigated by a trial of observation in those presenting with early symptom onset.

IMPORTANCE: In 2010, the Accreditation Council for Graduate Medical Education (ACGME) proposed increased regulation of work hours and supervision for residents. New Common Program requirements that took effect in July 2011 dramatically changed the customary 24-hour in-house call schedule. Surgical residents are more likely to be affected by these duty hour restrictions. OBJECTIVE: To examine surgical residents' views of the 2011 ACGME Common Program requirements after implementation in July 2011. DESIGN: A 20-question electronic survey was administered 6 months after implementation of 2011 ACGME regulations to 123 participating institutions. SETTING: ACGME-accredited teaching hospitals in the United States and US territories. PARTICIPANTS: The total sample was 1013 voluntarily participating residents in general surgery and surgical specialties at ACGME-accredited institutions. MAIN OUTCOMES AND MEASURES: Residents' perceptions of changes in education, patient care, and quality of life after institution of 2011 ACGME duty hour regulations and their compliance with these rules. RESULTS: A subset of 1013 residents training in general surgery or a surgical subspecialty was identified from a demographically representative sample of 6202 survey respondents. Most surgical residents indicated that education (55.1%), preparation for senior roles (68.4%), and work schedules (50.7%) are worse after implementation of the 2011 regulations. They reported no change in supervision (80.8%), safety of patient care (53.4%), or amount of rest (57.8%). Although quality of life is perceived as better for interns (61.9%), most residents believe that it is worse for senior residents (54.4%). A majority report increased handoffs (78.2%) and a shift of junior-level responsibilities to senior residents (68.7%). Finally, many residents report noncompliance (67.6%) and duty hour falsification (62.1%). CONCLUSIONS AND RELEVANCE: A majority of surgical residents disapprove of 2011 ACGME Common Program requirements (65.9%). The proposed benefits of the increased duty hour restrictions-improved education, patient care, and quality of life-have ostensibly not borne out in surgical training. It may be difficult for residents, particularly in surgical fields, to learn and care for patients under the 2011 ACGME regulations.
