INTRODUCTION - Double aortic arch is a rare congenital malformation of the aortic arch that most frequently presents in childhood. Early surgical intervention typically yields excellent outcomes.
OBJECTIVES - To describe aortotracheal fistula as a rare, yet serious complication of vascular ring and subsequent aortic aneurysm in an adult patient.
METHODS - Clinical history, as well as radiographic and endoscopic imaging were obtained to describe the development, diagnosis, and clinical course of this patient's aortotracheal fistula. Additionally, follow up data was obtained to document the healing of this fistula after surgical repair.
RESULTS - We describe a case of a 46-year-old male with DiGeorge Syndrome and a double aortic arch, repaired in childhood, which developed into an aortotracheal fistula after tracheostomy placement as an adult.
CONCLUSIONS - This case demonstrates that dangerous complications of a double aortic arch can persist into adulthood, even after surgical repair in infancy. Each patient's unique anatomy must be considered when thinking about airway management and prevention of complications of this rare congenital anomaly.

Amin SN, Rodney JP, Gelbard A
(2019) Ann Otol Rhinol Laryngol 128: 1194-1197
MeSH Terms: Adult, Airway Extubation, Cough, Female, Humans, Mucus, Paraplegia, Postoperative Complications, Spinal Cord Injuries, Tracheal Stenosis, Tracheotomy
Show Abstract · Added July 30, 2020
OBJECTIVES - To describe a case of open airway surgery with postoperative respiratory complications in a paraplegic woman and to review the unique respiratory physiology seen in patients with a history of cervical or thoracic spinal cord injury (SCI).
METHODS - Case report and literature review.
RESULTS - We describe the case of a 25-year-old paraplegic who developed tracheal stenosis after tracheotomy, eventually requiring tracheal resection and re-anastomosis. Her postoperative course was complicated by mucus plugging and severe atelectasis, necessitating reintubation. After extubation, the patient reported difficulty expectorating secretions ever since her SCI, requiring manual abdominal pressure from her family members to assist her when she needed to cough.
CONCLUSION - This first report of cricotracheal resection in a patient with paraplegia following SCI highlights the importance of an and demonstrates the unique respiratory management necessary for patients with SCI.

OBJECTIVE - To identify nonclinical factors affecting postoperative complication rates in patients with neurogenic bladder undergoing benign genitourinary (GU) reconstruction.
METHODS - Adult patients with neurogenic bladder undergoing benign GU reconstruction between October 2010 and November 2015 were included. Patients were excluded if a diversion was performed for malignancy, if patients had a history of radiation or if a new bowel segment was not utilized at the time of the operation. Clinical and nonclinical factors were abstracted from the patients' electronic medical records. Health literacy was assessed via the Brief Health Literacy Screen (BHLS), a validated 3-question assessment. Education, marital status, and distance from the medical center were also queried.
RESULTS - Forty-nine patients with a neurogenic bladder undergoing complex GU reconstruction met inclusion and exclusion criteria. On average, patients lived 111 miles (standard deviation 89) from the hospital. Overall, mean BHLS score was 10.4 (standard deviation 4.6) with 35% of patients scoring a BHLS of ≤9. Mean years of educational attainment was 9.7, and only 31% of patients completed high school education. In the first month after surgery, 37 patients (76%) experienced a complication, and 22% were readmitted; however, analysis of complication data did not identify an association between any nonclinical variables and complication rates.
CONCLUSION - Nonclinical factors including unmarried status, poor health literacy, and marked distance from quaternary care are prevalent in patients with neurogenic bladder undergoing complex GU reconstruction. To mitigate these potential risk factors, the authors recommend acknowledgment of these factors and multidisciplinary support perioperatively to counteract them.

Association Between Early Postoperative Acetaminophen Exposure and Acute Kidney Injury in Pediatric Patients Undergoing Cardiac Surgery.
Van Driest SL, Jooste EH, Shi Y, Choi L, Darghosian L, Hill KD, Smith AH, Kannankeril PJ, Roden DM, Ware LB
(2018) JAMA Pediatr 172: 655-663
MeSH Terms: Acetaminophen, Acute Kidney Injury, Antioxidants, Cardiac Surgical Procedures, Child, Preschool, Creatinine, Dose-Response Relationship, Drug, Drug Administration Schedule, Female, Humans, Infant, Male, Postoperative Care, Postoperative Complications, Postoperative Period, Retrospective Studies, Treatment Outcome
Show Abstract · Added March 24, 2020
Importance - Acute kidney injury (AKI) is a common and serious complication for pediatric cardiac surgery patients associated with increased morbidity, mortality, and length of stay. Current strategies focus on risk reduction and early identification because there are no known preventive or therapeutic agents. Cardiac surgery and cardiopulmonary bypass lyse erythrocytes, releasing free hemoglobin and contributing to oxidative injury. Acetaminophen may prevent AKI by reducing the oxidation state of free hemoglobin.
Objective - To test the hypothesis that early postoperative acetaminophen exposure is associated with reduced risk of AKI in pediatric patients undergoing cardiac surgery.
Design, Setting, and Participants - In this retrospective cohort study, the setting was 2 tertiary referral children's hospitals. The primary and validation cohorts included children older than 28 days admitted for cardiac surgery between July 1, 2008, and June 1, 2016. Exclusion criteria were postoperative extracorporeal membrane oxygenation and inadequate serum creatinine measurements to determine AKI status.
Exposures - Acetaminophen exposure in the first 48 postoperative hours.
Main Outcomes and Measures - Acute kidney injury based on Kidney Disease: Improving Global Outcomes serum creatinine criteria (increase by ≥0.3 mg/dL from baseline or at least 1.5-fold more than the baseline [to convert to micromoles per liter, multiply by 88.4]) in the first postoperative week.
Results - The primary cohort (n = 666) had a median age of 6.5 (interquartile range [IQR], 3.9-44.7) months, and 341 (51.2%) had AKI. In unadjusted analyses, those with AKI had lower median acetaminophen doses than those without AKI (47 [IQR, 16-88] vs 78 [IQR, 43-104] mg/kg, P < .001). In logistic regression analysis adjusting for age, cardiopulmonary bypass time, red blood cell distribution width, postoperative hypotension, nephrotoxin exposure, and Risk Adjustment for Congenital Heart Surgery score, acetaminophen exposure was protective against postoperative AKI (odds ratio, 0.86 [95% CI, 0.82-0.90] per each additional 10 mg/kg). Findings were replicated in the validation cohort (n = 333), who had a median age of 14.1 (IQR, 3.9-158.2) months, and 162 (48.6%) had AKI. Acetaminophen doses were 60 (95% CI, 40-87) mg/kg in those with AKI vs 70 (95% CI, 45-94) mg/kg in those without AKI (P = .03), with an adjusted odds ratio of 0.91 (95% CI, 0.84-0.99) for each additional 10 mg/kg.
Conclusions and Relevance - These results indicate that early postoperative acetaminophen exposure may be associated with a lower rate of AKI in pediatric patients who undergo cardiac surgery. Further analysis to validate these findings, potentially through a prospective, randomized trial, may establish acetaminophen as a preventive agent for AKI.

Objective To determine the factors associated with intra- and postoperative cerebrospinal fluid (CSF) leaks in setting of endoscopic transsphenoidal sellar surgery. Study Design Retrospective cohort. Setting Tertiary referral center. Subjects and Methods This study included 806 patients who underwent endoscopic transsphenoidal sellar surgery between 2004 and 2016. The associations between CSF leaks (intra- and postoperative) and patient demographics, medical history, tumor characteristics, and intraoperative repair techniques were analyzed. Results In sum, 205 (25.4%) patients had a CSF leak: 188 (23.3%) intraoperative leaks and 38 (4.7%) postoperative leaks. Twenty-one (2.6%) patients had postoperative leaks after having repair of an intraoperative leak; 55% of patients with a postoperative leak had an intraoperative leak repaired. On multivariate analysis, body mass index (BMI), hydrocephalus, suprasellar extension, and craniopharyngioma significantly predicted intraoperative CSF leaks, while only BMI and hydrocephalus predicted postoperative CSF leaks. Patients having septal flap repairs of CSF leaks had a higher postoperative leak rate relative to other repair techniques (odds ratio, 6.37; P = .013). Rigid reconstruction did not correlate with leaks. Conclusion For this large cohort of patients undergoing endoscopic transsphenoidal sellar surgery, BMI and hydrocephalus were identified as predictors of postoperative CSF leaks, including those occurring after repair of intraoperative leak. These variables may put stress on the surgical repair of sellar defects, and consideration of these risk factors may help counsel patients and guide perioperative decision making in regard to repair strategies and CSF diversion techniques.

Show Abstract · Added January 16, 2018
PURPOSE - Nephrolithiasis is an increasingly common ailment in the United States. Ureteroscopic management has supplanted shockwave lithotripsy as the most common treatment of upper tract stone disease. Ureteral stricture is a rare but serious complication of stone disease and its management. The impact of new technologies and more widespread ureteroscopic management on stricture rates is unknown. We describe our experience in managing strictures incurred following ureteroscopy for upper tract stone disease.
MATERIALS AND METHODS - Records for patients managed at four tertiary care centers between December 2006 and October 2015 with the diagnosis of ureteral stricture following ureteroscopy for upper tract stone disease were retrospectively reviewed. Study outcomes included number and type (endoscopic, reconstructive, or nephrectomy) of procedures required to manage stricture.
RESULTS - Thirty-eight patients with 40 ureteral strictures following URS for upper tract stone disease were identified. Thirty-five percent of patients had hydronephrosis or known stone impaction at the time of initial URS, and 20% of cases had known ureteral perforation at the time of initial URS. After stricture diagnosis, the mean number of procedures requiring sedation or general anesthesia performed for stricture management was 3.3 ± 1.8 (range 1-10). Eleven strictures (27.5%) were successfully managed with endoscopic techniques alone, 37.5% underwent reconstruction, 10% had a chronic stent/nephrostomy, and 10 (25%) required nephrectomy.
CONCLUSIONS - The surgical morbidity of ureteral strictures incurred following ureteroscopy for stone disease can be severe, with a low success rate of endoscopic management and a high procedural burden that may lead to nephrectomy. Further studies that assess specific technical risk factors for ureteral stricture following URS are needed.

MeSH Terms: Enterocolitis, Necrotizing, Humans, Infant, Newborn, Infant, Premature, Infant, Premature, Diseases, Neurodevelopmental Disorders, Neuropsychological Tests, Postoperative Complications
Show Abstract · Added June 27, 2018
The majority of surviving infants with surgical necrotizing enterocolitis (NEC) will have some degree of neurodevelopmental impairment. The impact of specific medial and surgical treatments for infants with severe NEC remains largely unknown but is being actively investigated. It is incumbent upon all providers caring for these infants to continue to focus on long term neurodevelopmental outcomes and to develop more widespread methods of neurodevelopmental assessment.

High-Density Lipoprotein Cholesterol Concentration and Acute Kidney Injury After Cardiac Surgery.
Smith LE, Smith DK, Blume JD, Linton MF, Billings FT
(2017) J Am Heart Assoc 6:
MeSH Terms: Acute Kidney Injury, Aged, Aged, 80 and over, Atorvastatin, Cardiac Surgical Procedures, Cholesterol, HDL, Coronary Artery Disease, Dose-Response Relationship, Drug, Double-Blind Method, Female, Follow-Up Studies, Humans, Hydroxymethylglutaryl-CoA Reductase Inhibitors, Kidney Function Tests, Male, Middle Aged, Postoperative Complications, Postoperative Period, Preoperative Period, Risk Factors, Treatment Outcome
Show Abstract · Added April 10, 2018
BACKGROUND - Acute kidney injury (AKI) after cardiac surgery is associated with increased short- and long-term mortality. Inflammation, oxidative stress, and endothelial dysfunction and damage play important roles in the development of AKI. High-density lipoproteins (HDLs) have anti-inflammatory and antioxidant properties and improve endothelial function and repair. Statins enhance HDL's anti-inflammatory and antioxidant capacities. We hypothesized that a higher preoperative HDL cholesterol concentration is associated with decreased AKI after cardiac surgery and that perioperative statin exposure potentiates this association.
METHODS AND RESULTS - We tested our hypothesis in 391 subjects from a randomized clinical trial of perioperative atorvastatin to reduce AKI after cardiac surgery. A 2-component latent variable mixture model was used to assess the association between preoperative HDL cholesterol concentration and postoperative change in serum creatinine, adjusted for known AKI risk factors and suspected confounders. Interaction terms were used to examine the effects of preoperative statin use, preoperative statin dose, and perioperative atorvastatin treatment on the association between preoperative HDL and AKI. A higher preoperative HDL cholesterol concentration was independently associated with a decreased postoperative serum creatinine change (=0.02). The association between a high HDL concentration and an attenuated increase in serum creatinine was strongest in long-term statin-using patients (=0.008) and was further enhanced with perioperative atorvastatin treatment (=0.004) and increasing long-term statin dose (=0.003).
CONCLUSIONS - A higher preoperative HDL cholesterol concentration was associated with decreased AKI after cardiac surgery. Preoperative and perioperative statin treatment enhanced this association, demonstrating that pharmacological potentiation is possible during the perioperative period.

BACKGROUND - Surgical resection is the cornerstone of curative-intent therapy for patients with hilar cholangiocarcinoma (HC). The role of vascular resection (VR) in the treatment of HC in western centres is not well defined.
METHODS - Utilizing data from the U.S. Extrahepatic Biliary Malignancy Consortium, patients were grouped into those who underwent resection for HC based on VR status: no VR, portal vein resection (PVR), or hepatic artery resection (HAR). Perioperative and long-term survival outcomes were analyzed.
RESULTS - Between 1998 and 2015, 201 patients underwent resection for HC, of which 31 (15%) underwent VR: 19 patients (9%) underwent PVR alone and 12 patients (6%) underwent HAR either with (n = 2) or without PVR (n = 10). Patients selected for VR tended to be younger with higher stage disease. Rates of postoperative complications and 30-day mortality were similar when stratified by vascular resection status. On multivariate analysis, receipt of PVR or HAR did not significantly affect OS or RFS.
CONCLUSION - In a modern, multi-institutional cohort of patients undergoing curative-intent resection for HC, VR appears to be a safe procedure in a highly selected subset, although long-term survival outcomes appear equivalent. VR should be considered only in select patients based on tumor and patient characteristics.

BACKGROUND - The objective of this study is to evaluate use of the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) online risk calculator for estimating common outcomes after operations for gallbladder cancer and extrahepatic cholangiocarcinoma.
METHODS - Subjects from the United States Extrahepatic Biliary Malignancy Consortium (USE-BMC) who underwent operation between January 1, 2000 and December 31, 2014 at 10 academic medical centers were included in this study. Calculator estimates of risk were compared to actual outcomes.
RESULTS - The majority of patients underwent partial or major hepatectomy, Whipple procedures or extrahepatic bile duct resection. For the entire cohort, c-statistics for surgical site infection (0.635), reoperation (0.680) and readmission (0.565) were less than 0.7. The c-statistic for death was 0.740. For all outcomes the actual proportion of patients experiencing an event was much higher than the median predicted risk of that event. Similarly, the group of patients who experienced an outcome did have higher median predicted risk than those who did not.
CONCLUSIONS - The ACS NSQIP risk calculator is easy to use but requires further modifications to more accurately estimate outcomes for some patient populations and operations for which validation studies show suboptimal performance.
