Retrograde intussusception seven years after a laparoscopic Roux-en-Y gastric bypass.

Intussusception after Roux-en-Y gastric bypass is more common than previously believed. It usually occurs between one and three years post-operatively, though we present a case that presented with a retrograde intussusception necessitating bowel resection seven years after a laparoscpic Roux-en-Y gastric bypass. The diagnosis and etiological theories are discussed based on findings from the literature.

Effectiveness of Fluconazole Prophylaxis in a Targeted High-Risk Group in a Surgical Intensive Care Unit.

Background: Candidemia is an important nosocomial infection in intensive care units (ICUs), with total parenteral nutrition (TPN) a well-recognized risk factor. Antifungal prophylaxis may be an effective intervention to prevent candidemia in high-risk patients. In this report, the effectiveness of fluconazole prophylaxis was examined in patients located in a combined surgical-neurosurgical ICU serving an urban Level 1 trauma center who were receiving prolonged courses of TPN. Methods: Fluconazole was administered prophylactically for patients receiving TPN for more than six days. Rates of candidemia during the intervention were compared with those prior to the intervention. Results: During the 27-month pre-intervention period, seven episodes of candidemia occurred during 1,277 days of parenteral nutrition therapy. During the 17-month post-intervention period, there were zero episodes during 852 days of therapy (p = 0.03). Similarly, during the pre-intervention period, there were six episodes of candidemia during 867 high-risk days of therapy, compared with zero during 643 days of high-risk therapy in the post-intervention period (p = 0.04). The rates of bacteremia did not change, and emergence of fluconazole-resistant Candida species was not evident. Conclusions: At our surgical ICU, this fluconazole prophylaxis was associated with a significant decrease in the number of patients with candidemia, without emergence of resistant species.

Health disparity in complicated colorectal cancer.

The purpose of this study was to assess for disparity within a cohort of patients presenting with complicated colorectal cancer. A retrospective study of 522 patients who underwent surgery for colorectal cancer at a tertiary care institution was performed. Complicated cancer was defined by perforating or obstructing colonic lesions. Statistical analysis was conducted by chi2 test and analysis of variance. Of the 522 patients, 72 patients (14%) presented with complicated colorectal cancer. Blacks in low-income brackets (36 vs 0%, P < 0.001) and those with public insurance (55 vs 16%, P < 0.05) had increased presentation with complicated colorectal cancers as compared with whites. Black (91%) and Hispanic women (86%), when compared with white women (37%) had increased incidence of complicated colorectal cancer (P < 0.05). Patients in low-income brackets, regardless of race, had increased cancer recurrence rates (57 vs 8%, P < 0.001) compared with patients in average or high-income brackets. Mortality rate was 57 per cent in Hispanic, 29 per cent in white, and 27 per cent in black patients (P = nonsignificant). Specific targeting of colorectal cancer screening, education, and follow-up programs is imperative for minority women and patients of low socioeconomic status.

Staffing Up For The Surge: Expanding The New York City Public Hospital Workforce During The COVID-19 Pandemic.

Confronted with the coronavirus disease 2019 (COVID-19) pandemic, New York City Health + Hospitals, the city's public health care system, rapidly expanded capacity across its eleven acute care hospitals and three new field hospitals. To meet the unprecedented demand for patient care, NYC Health + Hospitals redeployed staff to the areas of greatest need and redesigned recruiting, onboarding, and training processes. The hospital system engaged private staffing agencies, partnered with the Department of Defense, and recruited volunteers throughout the country. A centralized onboarding team created a single-source portal for medical care providers requiring credentialing and established new staff positions to increase efficiency. Using new educational tools focused on COVID-19 content, the hospital system trained twenty thousand staff members, including nearly nine thousand nurses, within a two-month period. Creation of multidisciplinary teams, frequent enterprisewide communication, willingness to shift direction in response to changing needs, and innovative use of technology were the key factors that enabled the hospital system to meet its goals.

Critical Care And Emergency Department Response At The Epicenter Of The COVID-19 Pandemic.

New York City has emerged as the global epicenter for the coronavirus disease 2019 (COVID-19) pandemic. The city's public health system, New York City Health + Hospitals, has been key to the city's response because its vulnerable patient population is disproportionately affected by the disease. As the number of cases rose in the city, NYC Health + Hospitals carried out plans to greatly expand critical care capacity. Primary intensive care unit (ICU) spaces were identified and upgraded as needed, and new ICU spaces were created in emergency departments, procedural areas, and other inpatient units. Patients were transferred between hospitals to reduce strain. Critical care staffing was supplemented by temporary recruits, volunteers, and Department of Defense medical personnel. Supplies needed to deliver critical care were monitored closely and replenished to prevent interruptions. An emergency department action team was formed to ensure that the experience of front-line providers was informing network-level decisions. The steps taken by NYC Health + Hospitals greatly expanded its capacity to provide critical care during an unprecedented surge of COVID-19 cases in NYC. These steps, along with lessons learned, could inform preparations for other health systems during a primary or secondary surge of cases.

Evolution of the surgeon-volume, patient-outcome relationship.

OBJECTIVE: Higher surgeon volume is associated with improved patient outcomes. This finding has prompted recommendations for increasing specialization and referrals to high-volume surgeons, yet their implementation in clinical practice has not been measured. METHODS: We performed cross-sectional analyses using 1999 and 2005 discharge information from the Health Care Utilization Project National Inpatient Sample to measure whether the number of procedures performed by high-volume surgeons increased over time. Procedures included those demonstrated to have strong surgeon volume-outcome associations in the literature. International Classification of Diseases, Ninth Revision codes were employed for colorectal procedures, esophagectomy, gastrectomy, pancreatectomy, thyroidectomy, coronary artery bypass graft surgery, and carotid endarterectomy. Bivariate analyses and hierarchical generalized linear models were employed to measure association between surgeon volume and length of stay (LOS) and mortality or complications. RESULTS: There was a significant increase in the proportion of procedures performed by high-volume surgeons over time, with the most dramatic increases seen for gastrectomy (54%), pancreatectomy (31%), and thyroidectomy (23%). Having a procedure performed by a high-volume surgeon was associated with patient race and insurance status. Overall, unadjusted mortality and LOS were significantly lower for high-volume surgeons compared with low-volume surgeons in 1999 and 2005. In multivariable hierarchical generalized linear models, only differences in LOS by surgeon volume remained significant in both years. CONCLUSIONS: The proportion of procedures performed by high-volume surgeons increased over a 6-year period, as evidence mounted in support of a surgeon volume-outcome association. Efforts are still needed to improve access among underserved subsets of the population and eliminate apparent disparities based on patient race and insurance status.

Challenge of uncontrolled enteroatmospheric fistulas.

INTRODUCTION: With the popularization of damage control surgery and the use of the open abdomen, a new permutation of fistula arose; the enteroatmospheric fistula (EAF), an opening of exposed intestine spilling uncontrollably into the peritoneal cavity. EAF is the most devastating complication of the open abdomen. We describe and analyze a single institution's experience in controlling high-output EAFs in patients with peritonitis. METHODS: We analyzed 189 consecutive procedures to achieve and maintain definitive control of 24 EAFs in 13 patients between 2006 and 2017. EAFs followed surgery for either trauma (seven patients) or non-traumatic abdominal conditions (six patients). All procedures were mapped onto an operative timeline and analyzed for: success in achieving definitive control, number of reoperations, and feasibility of bedside procedures in the surgical intensive care unit. The end point was controlled enteric drainage through a healed abdominal wound. RESULTS: There was a mean delay of 8.5 days (range 2-46 days) from the index operation until the EAF was identified. Most EAFs required several attempts (mean: 2.7 per patient, range 1-7) until definitive control was achieved. Multiple reoperations were then required to maintain control (mean: 13). While the most effective techniques were endoscopic (1) and proximal diversion (1), these were applicable only in select circumstances. A 'floating stoma' where the fistula edges are sutured to an opening in a temporary closure device, while technically effective, required multiple reoperations. Tube drainage through a negative pressure dressing (tube vac) required the most maintenance usually through bedside procedures. Primary closure almost always failed. Twelve of the 13 patients survived. CONCLUSION: An EAF is a highly complex surgical challenge. Successful source control of the potentially lethal ongoing peritonitis requires tenacity and tactical flexibility. The appropriate control technique is often found by trial and error and must be creatively tailored to the individual circumstances of the patient.

Clinical and economic outcomes of thyroid and parathyroid surgery in children.

CONTEXT: Clinical and economic outcomes after thyroidectomy/parathyroidectomy in adults have demonstrated disparities based on patient age and race/ethnicity; there is a paucity of literature on pediatric endocrine outcomes. OBJECTIVE: The objective was to examine the clinical and demographic predictors of outcomes after pediatric thyroidectomy/parathyroidectomy. DESIGN: This study is a cross-sectional analysis of Healthcare Cost and Utilization Project-National Inpatient Sample hospital discharge information from 1999-2005. All patients who underwent thyroidectomy/parathyroidectomy were included. Bivariate and multivariate analyses were performed to identify independent predictors of patient outcomes. SUBJECTS: Subjects included 1199 patients 17 yr old or younger undergoing thyroidectomy/parathyroidectomy. MAIN OUTCOME MEASURES: Outcome measures included in-hospital patient complications, length of stay (LOS), and inpatient hospital costs. RESULTS: The majority of patients were female (76%), aged 13-17 yr (71%), and White (69%). Whites were more often in the highest income group (80% vs. 8% for Hispanic and 6% for Black; P < 0.01) and had private/HMO insurance (76% vs. 10% for Hispanic and 5% for Black; P < 0.001) rather than Medicaid (13% vs. 32% for Hispanic and 41% for Black; P < 0.001). Ninety-one percent of procedures were thyroidectomies and 9% parathyroidectomies. Children aged 0-6 yr had higher complication rates (22% vs. 15% for 7-12 yr and 11% for 13-17 yr; P < 0.01), LOS (3.3 d vs. 2.3 for 7-12 yr and 1.8 for 13-17 yr; P < 0.01), and higher costs. Compared with children from higher-income families, those from lower-income families had higher complication rates (11.5 vs. 7.7%; P < 0.05), longer LOS (2.7 vs. 1.7 d; P < 0.01), and higher costs. Children had higher endocrine-specific complication rates than adults after parathyroidectomy (15.2 vs. 6.2%; P < 0.01) and thyroidectomy (9.1 vs. 6.3%; P < 0.01). CONCLUSIONS: Children undergoing thyroidectomy/parathyroidectomy have higher complication rates than adult patients. Outcomes were optimized when surgeries were performed by high-volume surgeons. There appears to be disparity in access to high-volume surgeons for children from low-income families, Blacks, and Hispanics.

Accuracy of Physical Examination, Ankle-Brachial Index, and Ultrasonography in the Diagnosis of Arterial Injury in Patients With Penetrating Extremity Trauma: A Systematic Review and Meta-analysis.

BACKGROUND: Penetrating Extremity Trauma (PET) may result in arterial injury, a rare but limb- and life-threatening surgical emergency. Timely, accurate diagnosis is essential for potential intervention in order to prevent significant morbidity. OBJECTIVES: Using a systematic review/meta-analytic approach, we determined the utility of physical examination, Ankle-Brachial Index (ABI), and Ultrasonography (US) in the diagnosis of arterial injury in emergency department (ED) patients who have sustained PET. We applied a test-treatment threshold model to determine which evaluations may obviate CT Angiography (CTA). METHODS: We searched PubMed, Embase, and Scopus from inception to November 2016 for studies of ED patients with PET. We included studies on adult and pediatric subjects. We defined the reference standard to include CTA, catheter angiography, or surgical exploration. When low-risk patients did not undergo the reference standard, trials must have specified that patients were observed for at least 24 hours. We used the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2) to evaluate bias and applicability of the included studies. We calculated positive and negative likelihood ratios (LR+ and LR-) of physical examination ("hard signs" of vascular injury), US, and ABI. Using established CTA test characteristics (sensitivity = 96.2%, specificity = 99.2%) and applying the Pauker-Kassirer method, we developed a test-treatment threshold model (testing threshold = 0.14%, treatment threshold = 72.9%). RESULTS: We included eight studies (n = 2,161, arterial injury prevalence = 15.5%). Studies had variable quality with most at high risk for partial and double verification bias. Some studies investigated multiple index tests: physical examination (hard signs) in three studies (n = 1,170), ABI in five studies (n = 1,040), and US in four studies (n = 173). Due to high heterogeneity (I2  > 75%) of the results, we could not calculate LR+ or LR- for hard signs or LR+ for ABI. The weighted prevalence of arterial injury for ABI was 14.3% and LR- was 0.59 (95% confidence interval [CI] = 0.48-0.71) resulting in a posttest probability of 9% for arterial injury. Ultrasonography had weighted prevalence of 18.9%, LR+ of 35.4 (95% CI = 8.3-151), and LR- of 0.24 (95% CI = 0.08-0.72); posttest probabilities for arterial injury were 89% and 5% after positive or negative US, respectively. The posttest probability of arterial injury with positive US (89%) exceeded the CTA treatment threshold (72.9%). The posttest probabilities of arterial injury with negative US (5%) and normal ABI (9%) exceeded the CTA testing threshold (0.14%). Normal examination (no hard or soft signs) with normal ABI in combination had LR- of 0.01 (95% CI = 0.0-0.10) resulting in an arterial injury posttest probability of 0%. CONCLUSIONS: In PET patients, positive US may obviate CTA. In patients with a normal examination (no hard or soft signs) and a normal ABI, arterial injury can be ruled out. However, a normal ABI or negative US cannot independently exclude arterial injury. Due to high study heterogeneity, we cannot make recommendations when hard signs are present or absent or when ABI is abnormal. In these situations, one should use clinical judgment to determine the need for further observation, CTA or catheter angiography, or surgical exploration.

Correlation of Venous Lactate and Time of Death in Emergency Department Patients with Noncritical Lactate Levels and Mortality from Trauma.

BACKGROUND: Serum venous lactate (LAC) levels help guide emergency department (ED) resuscitation of patients with major trauma. Critical LAC level (CLAC, ≥4.0 mmol/L) is associated with increased disease severity and higher mortality in injured patients. The characteristics of injured patients with non-CLAC (NCLAC) (<4.0 mmol/L) and death have not been previously described. OBJECTIVES: (1) To describe the characteristics of patients with venous NCLAC and death from trauma. (2) To assess the correlation of venous NCLAC with time of death. METHODS: A retrospective cohort study at an urban teaching hospital between 9/2011 and 8/2014. Inclusion: All trauma patients (all ages) who presented to the ED with any injury and met all criteria: (1) Venous LAC drawn at the time of arrival that resulted in an NCLAC level; (2) were admitted to the hospital; (3) died during their hospitalization. Exclusion: CLAC. Outcome: Correlation of NCLAC and time of death. Data were extracted from an electronic medical record by trained data abstractors using a standardized protocol. Cross-checks were performed on 10% of data entries and inter-observer agreement was calculated. Data were explored using descriptive statistics and Kaplan-Meier curves were created to define survival estimates. Data are presented as percentages with 95% confidence interval (CI) for proportions and medians with quartiles for continuous variables. Kaplan-Meier curves with differences in time to events based on LAC are used to analyze the data. RESULTS: A total of 60 patients met the inclusion criteria. The median age was 52 years (quartiles: 30, 75) and 73% were male (age range 2-92). The median LAC in the overall cohort was 1.9 mmol/L (quartiles: 1.5, 2.1). Sixteen patients (27%) died during the first 24 h with 5 (31%) due to intracranial hemorrhage. The median survival time was 5.6 days (134.4 h) (95% CI: 2.3-12.6). CONCLUSIONS: In trauma patients with NCLAC who died during the index hospitalization, the median survival time was 5.6 days, approximately one-third of patients died within the first 24 h. These findings indicate that relying on a triage NCLAC level alone may result in underestimating injury severity and subsequent morbidity and mortality.

Arterial embolization of retained kidney remnant following blunt traumatic injury: A case report.

INTRODUCTION: There has been a recent trend toward nonoperative management of solid organ injuries with arteriography and embolization as alternatives to surgical exploration. We examine the use of arterial embolization in the management of a post-subtotal nephrectomy urinoma in a patient with severe renal injury secondary to blunt trauma. METHODS: This case report has been reported in line with the CARE criteria [13]. PRESENTATION OF CASE: A 35-year-old female patient presented with a persistent urinoma after an incomplete nephrectomy for blunt renal trauma. Computed tomography scan of the abdomen demonstrated a 47×68×101 mm3 collection superior to the remnant of the resected right kidney. With persistence of the urinoma after placement of an 8 French drainage catheter, the patient was taken for arterial embolization of the lower renal artery for ablation of the kidney remnant. DISCUSSION: Most kidney injuries with urinoma formation are treated successfully with supportive measures, however refractory cases require intervention. Arterial embolization has been used successfully in the treatment of traumatic pseudoaneurysms, arteriovenous fistulas, and some renal tumors. In this patient, we extended the use of embolization to infarct vessels of the functioning kidney remnant as an alternative to surgery. Post-embolization the patient recovered well with permanent resolution of the urinoma and short-term side effects limited to short-lived fever and lumbar pain. CONCLUSION: Arterial embolization should be considered as an alternative to surgery in cases of persistent urinoma following renal trauma with retained remnants.

Parathyroidectomy improves neurocognitive deficits in patients with primary hyperparathyroidism.

BACKGROUND: Clinical guidelines for the treatment of primary hyperparathyroidism (pHPT) often suggest parathyroidectomy, but generally fail to consider neurocognitive and psychiatric symptoms because of the relative paucity of evidence. METHODS: In this prospective study, patients with pHPT (PTX) and benign euthyroid thyroid disease (THY) referred for operation were evaluated pre- and postoperatively with validated psychometric and neurocognitive instruments to determine whether learning, memory, or concentration improved with after parathyroidectomy. Statistical comparisons between groups were performed with univariate analysis and repeated measures of analysis of variance. RESULTS: Fifty-five subjects, mean age of 54 years, were evaluated preoperatively; 41 returned postoperatively. There were no significant differences between groups by age and gender. PTXs reported more depression symptoms preoperatively (P = .04) that improved postoperatively. There were no differences between the 2 groups on verbal memory and trait anxiety. For PTXs, average preoperative serum calcium concentration (11.3 mg/dL) and serum PTH level (100 pg/mL) normalized postoperatively. Preoperatively PTXs showed greater delays in their spatial learning (P = .03). All subjects learned across the 5 trials, but PTXs were more delayed (P = .03). After operation, PTXs improved and functioned at a level equivalent to the THYs. There was an interaction between trial (neurocognitive testing), visit (pre- vs postoperative), status (PTX vs THY), and change in PTH level (P = .06), suggesting that individuals with greater change in PTH were more likely to improve in their learning efficiency postparathyroidectomy. CONCLUSIONS: PHPT may be associated with a spatial learning deficit and processing that improves after parathyroidectomy. While longer-term follow-up is necessary, neurocognitive symptoms perhaps should be considered as criteria for parathyroidectomy.

Health services research in endocrine surgery.

PURPOSE OF REVIEW: We review recent health services research studies examining clinical and economic outcomes in endocrine surgery. RECENT FINDINGS: Recent studies have focused on such important issues as the use of the Internet in medicine, patient quality of life, cost-effectiveness of emerging surgical technologies, and labor-force modeling. There is a need for accurate and informative websites dedicated to thyroid disease, given the large number of patients who use the Internet for healthcare information. Debate continues about the relative merits of medical and surgical therapy for primary hyperparathyroidism; based on measurements of quality of life and cost-effectiveness, parathyroidectomy appears to be favored. Surgical outcomes studies have shown parathyroidectomy to be safe in octogenarian and nonagenarian patients with primary hyperparathyroidism. Sophisticated work-force projections suggest that the supply of endocrine surgeons will grow over the next 15 years, but will be outpaced by the anticipated demand. SUMMARY: Health services research is a burgeoning field of investigation in endocrine surgery. It needs to be developed to improve the quality of care of patients with thyroid, parathyroid, adrenal and endocrine pancreatic diseases.

A population-based study of outcomes from thyroidectomy in aging Americans: at what cost?

BACKGROUND: We wanted to evaluate clinical and economic outcomes after thyroidectomy in patients 65 years of age and older, with special analyses of those aged 80 years and older, in the US. STUDY DESIGN: This was a population-based study using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample, 2003-2004, a national administrative database of all patients undergoing thyroidectomy and their surgeon providers. Independent variables included patient demographic and clinical characteristics and surgeon descriptors, including case volume. Clinical and economic outcomes included mean total costs and length of stay (LOS), in-hospital mortality, discharge status, and complications. RESULTS: There were 22,848 patients who underwent thyroidectomies, including 4,092 (18%) aged 65 to 79 years and 744 (3%) 80 years of age or older. On a population level, patient age is an independent predictor of clinical and economic outcomes. Average LOS for patients 80 years and older is 60% longer than for similar patients 65 to 79 years of age (2.9 versus 2.2 days; p < 0.001), complication rates are 34% higher (5.6% versus 2.1%; p < 0.001), and total costs are 28% greater ($7,084 versus $5,917; p < 0.001). High-volume surgeons have shorter LOS and fewer complications but perform fewer thyroidectomies for aging Americans; although they do nearly 29% of these procedures in patients younger than 65 years, they do just 15% of thyroidectomies in patients 80 years and older and 23% in patients 65 to 79 years. CONCLUSIONS: On a population level, clinical and economic outcomes for patients 65 years and older undergoing thyroidectomies are considerably worse than for similar, younger patients. The majority of thyroidectomies in aging Americans is performed by low-volume surgeons. More data are needed about longterm outcomes, but increased referrals to high-volume surgeons for aging Americans are necessary.

Pediatric endocrine surgery: who is operating on our children?

BACKGROUND: High surgeon volume is associated with improved outcomes in adult endocrine surgery. This is the first population-based outcomes study for thyroidectomy/parathyroidectomy in children. METHODS: Cross-sectional analyses were performed using 1999 to 2005 Healthcare Cost and Utilization Project Nationwide Inpatient Sample data. Outcomes included complications, length of stay (LOS), and costs. High-volume surgeons performed >30 cervical endocrine procedures per year in adults and children; pediatric surgeons restricted >90% of their practices to patients

The maturation of a specialty: Workforce projections for endocrine surgery.

BACKGROUND: There has been an increase in the incidence of endocrine diseases and the number of endocrine procedures in the United States. Higher surgeon volume is associated with improved patient outcomes. Fellowship programs will lead to more specialty-trained endocrine surgeons. We make projections for the supply of endocrine surgeons and demand for endocrine procedures over the next 15 years. METHODS: Supply projections are based on data from the Accreditation Council for Graduate Medical Education, a survey of American Association of Endocrine Surgery fellowship program graduates, and Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS). Demand is estimated using HCUP-NIS, U.S. Census Bureau projections, and a literature review. RESULTS: There were 64,275 endocrine procedures performed in 2000 and 80,505 in 2004. Using age-adjusted population projections and increasing incidence of endocrine diseases, 103,704 endocrine procedures are anticipated in 2020. High-volume endocrine surgeons are few in number, but perform 24% of endocrine procedures. Surgeon supply is projected to increase to 938 by 2020; this is based on fellowship graduation rates, retirement trends, and increasing annual endocrine case volume among high-volume surgeons. Alternative projections of supply and demand are generated to test the sensitivity of our analyses to different assumptions. CONCLUSION: Labor force planning in endocrine surgery is essential if the demand for more high-volume endocrine specialists is to be met.
