Second harvest of Congenital Heart Surgery Database in Türkiye: Current outcomes.

Background: This second harvest of the Congenital Heart Surgery Database intended to compare current results with international databases. Methods: This retrospective study examined a total of 4007 congenital heart surgery procedures from 15 centers in the Congenital Heart Surgery Database between January 2018 and January 2023. International diagnostic and procedural codes were used for data entry. STAT (Society of Thoracic Surgeons and European Association for Cardiothoracic Surgery) mortality scores and categories were used for comparison of the data. Surgical priority status was modified from American Society of Anesthesiologist guidelines. Centers that sent more than 5 cases to the database were included to the study. Results: Cardiopulmonary bypass and cardioplegic arrest were performed in 2,983 (74.4%) procedures. General risk factors were present in 22.6% of the patients, such as genetic anomaly, syndrome, or prematurity. Overall, 18.9% of the patients had preoperative risk factors (e.g., mechanical ventilation, renal failure, and sepsis). Of the procedures, 610 (15.2%) were performed on neonates, 1,450 (36.2%) on infants, 1,803 (45%) on children, and 144 (3.6%) on adults. The operative timing was elective in 56.5% of the patients, 34.4% were urgent, 8% were emergent, and 1.1% were rescue procedures. Extracorporeal membrane oxygenation support was used in 163 (4%) patients, with a 34.3% survival rate. Overall mortality in this series was 6.7% (n=271). Risk for mortality was higher in patients with general risk factors, such as prematurity, low birth weight neonates, and heterotaxy syndrome. Mortality for patients with preoperative mechanical ventilation was 17.5%. Pulmonary hypertension and preoperative circulatory shock had 11.6% and 10% mortality rates, respectively. Mortality for patients who had no preoperative risk factor was 3.9%. Neonates had the highest mortality rate (20.5%). Intensive care unit and hospital stay time for neonates (median of 17.8 days and 24.8 days, respectively) were also higher than the other age groups. Infants had 6.2% mortality. Hospital mortality was 2.8% for children and 3.5% for adults. Mortality rate was 2.8% for elective cases. Observed mortality rates were higher than expected in the fourth and fifth categories of the STAT system (observed, 14.8% and 51.9%; expected, 9.9% and 23.1%; respectively). Conclusion: For the first time, outcomes of congenital heart surgery in Türkiye could be compared to the current world experience with this multicenter database study. Increased mortality rate of neonatal and complex heart operations could be delineated as areas that need improvement. The Congenital Heart Surgery Database has great potential for quality improvement of congenital heart surgery in Türkiye. In the long term, participation of more centers in the database may allow more accurate risk adjustment.

Congenital heart defects and postoperative follow-up of patients with Williams syndrome as a single center experience and review of the cases from Türkiye.

BACKGROUND: Cardiovascular system involvement is quite common and the leading cause of morbidity and mortality in patients with Williams syndrome (WS), most of whom need surgery. The present study aimed to provide a detailed evaluation of the features of surgical procedures and outcomes of patients with WS given as single-center experience, and additionally to make a detailed review from Türkiye. MATERIALS AND METHODS: Thirty-five children with WS diagnosed between the years 1992 and 2021 were evaluated retrospectively including cardiovascular data, surgical treatment features, and outcomes. A total of six articles from Türkiye were evaluated. RESULTS: A total of 35 patients with Williams Syndrome (24 male) with a median age of cardiologic diagnosis of 6 months (range, 2 days-6 years) were evaluated. The cardiac defects of the patients with WS were found as supravalvular aortic stenosis (SVAS) (n=30, 85%) and peripheral pulmonary stenosis (PPS) (n=21, 65%). Additional cardiac anomalies were seen in 71% patients. The rate of SVAS and PPS surgery in all patients with WS was 77.1%. The median surgical age of the patients was 2.5 years (range, 7 months-15.5 years). No patients died due to surgery. But one patient died because of ventricular tachycardia due to anesthesia at the beginning of angiography. A total of 138 (63% male) patients with WS were evaluated from the articles published in Türkiye. Of 138 patients, 64.4% had SVAS, 52.1% had PPS, and 39.8% had additional cardiac anomaly. The median follow-up period ranged from 17 months to 18 years, and six (4.3%) patients died in the early postoperative period. CONCLUSION: Cardiovascular system involvement is extremely common and is the leading cause of morbidity and mortality in patients with WS, often requiring surgical intervention. As seen in our study including 35 patients with WS and in publications from Türkiye, SVAS in patients with WS generally requires surgery, especially in the first year of life. PPS, on the other hand, requires surgery less frequently than SVAS, and pulmonary stenosis appears to decrease over time.

Pre- and postoperative levels of serum brain-derived neurotrophic factor in neonates with congenital heart defects.

BACKGROUND: The objectives of this study were to assess the preoperative and postoperative serum brain- derived neurotrophic factor (BDNF) levels in neonates undergoing surgery for congenital heart defects (CHD). Also to explore the relationship between changes in BDNF levels and the impact of perioperative factors including intraoperative body temperature, aortic cross-clamp time, perfusion time, operation time, inotropic score, vasoactive inotropic score and lactate levels. METHODS: Forty-four patients with CHD and 36 healthy neonates were included in the study. Blood samples for serum BDNF levels were collected three times: preoperatively, and at 24 and 72 hours postoperatively from each patient in the operated group. Additionally, samples were collected once from each individual in the non-operated case group and the control group. Serum BDNF levels were analyzed using the Elabscience ELISA (Enzyme-Linked Immunosorbent Assay) commercial kit. Cranial ultrasonography (USG) was performed on all infants with CHD. Following cardiac surgery, patients underwent second and third cranial USG examinations at 24 and 72 hours postoperatively, respectively. RESULTS: Forty-four consecutive patients with CHD were divided into two groups as follows: the operated group (n=30) and the non-operated group (n=14). Although there were no differences in the baseline serum BDNF levels between the case and control groups, the preoperative serum BDNF levels were significantly lower in the patients operated compared to the non-operated patients. The serum BDNF levels at the 24th hour postoperatively were higher than the preoperative levels. However, no significant correlation was found between the serum BDNF levels at 24 and 72 hours postoperatively as well as the cranial USG findings at corresponding times. CONCLUSIONS: Serum BDNF levels were initially lower in neonates with CHD who underwent surgery, but increased during the early postoperative period. These results suggest that serum BDNF levels are influenced by CHD and the postoperative period.

Pulmonary tumors in childhood.

Pulmonary tumors in childhood are rare, but the majority are malignant. The histopathologic spectrum is quite diverse, including inflammatory myofibroblastic tumor, hamartoma, primary pulmonary paraganglioma, carcinoid tumor, mucoepidermoid carcinoma, pleuropulmonary blastoma, adenocarcinoma, squamous cell carcinoma, and sarcomas. Nonspecific clinical and radiological findings result in late and incorrect diagnoses. Although surgical resection is the initial and proper treatment method, additional adjuvant therapy is dependent on both tumor stage and histopathologic type.

Oncological results in primary and secondary malignant chest wall tumors.

Background: This study aims to evaluate the oncological results of primary and secondary chest wall tumors treated with curative resections and to investigate possible prognostic factors. Methods: Between January 2010 and December 2021, a total of 77 patients (53 males, 24 females; median age: 59 years; range, 3 to 87 years) who underwent curative resection for malignant chest wall tumors were retrospectively analyzed. Each tumor was staged according to its histological type. Age, sex, tumor diameter, tumor type (primary/secondary), histological tumor type, grade, stage, complete resection, rib resection, reconstruction, neoadjuvant and adjuvant therapy, recurrence, and survival data were recorded. Results: Of the chest wall tumors, 33 (42.9%) were primary and 44 (57.1%) were secondary (local invasion, metastasis). Nine (11.7%) patients had positive surgical margins. Chest wall resection was most commonly performed due to lung cancer invasion (46.8%), followed by Ewing sarcoma (13%). Recurrence was observed in 34 (44.2%) patients. The five-year recurrence-free survival rate was 42.7% and the five-year overall survival rate was 58.6%. There was no significant difference between the primary and secondary tumors in terms of recurrence-free and overall survival (p=0.663 and p=0.313, respectively). In the multivariate analysis, tumor grade and rib resection were found to be independent prognostic factors for both recurrence-free survival (p=0.005 and p<0.001, respectively) and overall survival (p=0.048 and p=0.007, respectively). Conclusion: Successful oncological results can be achieved in wellselected patients with primary and secondary chest wall tumors. The grade of the tumor should be taken into account while determining the neoadjuvant or adjuvant treatment approach and surgical margin width. Rib resection should not be avoided when necessary.

Determination of Risk Factors for Acute Kidney Injury In Orthotopic Cardiac Transplantation.

BACKGROUND: In this study, we try to determine risk factors for acute kidney injury in orthotopic cardiac transplantation patients. METHODS: Between February 2003 and December 2022, all cardiac transplantation patients were retrospectively reviewed. Finally, 102 patients enrolled in this study. Demographic data, comorbidities, preoperative cardiac catheterization parameters, preoperative and postoperative blood test results, intraoperative parameters, acute kidney injury developed or not, stage of acute kidney injury, and whether renal replacement therapy was required or not was recorded. RESULTS: Of the 102 patients, 68 were male. Fifty-four of these patients developed acute kidney injury, and 31 required renal replacement therapy postoperatively. The mean age of developed acute kidney injury group (AKI+) was older than non-developed acute kidney injury group (non-AKI) (P = .01). The average body surface area of the AKI+ was 1.81 ± 0.32, whereas in non-AKI it was 1.57 ± 0.35 (P = .01). More patients were ex-smokers (P = .007) and had a history of hypertension (P= .011) in the AKI+ group. Preoperative serum creatinine was 1.12 ± 0.26 mg/dL in the AKI+ group and 0.82 ± 0.13 mg/dL in the non-AKI group (P = .02). The intraoperative urine output was 491.20 ± 276.48 mL for AKI+ and 676.45 ± 478.84 mL for the non-AKI group (P = .03). CONCLUSIONS: Acute kidney injury development after cardiac transplantation is common. In our study, high body surface area, older age, ex-smoker, hypertension, low intraoperative urine output, and high preoperative serum creatinine levels were risk factors for acute kidney injury development in cardiac transplantation patients. Mortality and morbidity after cardiac transplantation might be reduced if acute kidney injury development can be lowered.

Neonatal Outcomes of Critical Congenital Heart Defects: A Multicenter Epidemiological Study of Turkish Neonatal Society : Neonatal Outcomes of CCHD.

Critical congenital heart disease (CCHD) is one of the leading causes of neonatal and infant mortality. We aimed to elucidate the epidemiology, spectrum, and outcome of neonatal CCHD in Türkiye. This was a multicenter epidemiological study of neonates with CCHD conducted from October 2021 to November 2022 at national tertiary health centers. Data from 488 neonatal CCHD patients from nine centers were entered into the Trials-Network online registry system during the study period. Transposition of great arteria was the most common neonatal CHD, accounting for 19.5% of all cases. Sixty-three (12.9%) patients had extra-cardiac congenital anomalies. A total of 325 patients underwent cardiac surgery. Aortic arch repair (29.5%), arterial switch (25.5%), and modified Blalock-Taussig shunt (13.2%). Overall, in-hospital mortality was 20.1% with postoperative mortality of 19.6%. Multivariate analysis showed that the need of prostaglandin E1 before intervention, higher VIS (> 17.5), the presence of major postoperative complications, and the need for early postoperative extracorporeal membrane oxygenation were the main risk factors for mortality. The mortality rate of CCHD in our country remains high, although it varies by health center. Further research needs to be conducted to determine long-term outcomes for this vulnerable population.

Comparison of serum N-terminal pro-brain natriuretic peptide levels, conventional echocardiography, exercise parameters, and dyssynchrony measurements in Fontan patients.

INTRODUCTION: Little data are available concerning the methods used in the long-term follow-up of Fontan patients. We analyzed the association between serum N-terminal pro-brain natriuretic peptide levels, conventional echocardiography findings, exercise parameters, and dyssynchrony measurements in patients who underwent Fontan surgery. METHODS: This study included 28 patients who underwent Fontan surgery (mean age 12.8 ± 4.36 years) and 27 healthy controls (mean age 12.5 ± 3.76 years). Echocardiography examinations and exercise tests were performed in both groups. The systemic ventricle was examined via echocardiography, dyssynchrony measurement was performed, the systemic ventricular myocardial performance index was calculated, and serum N-terminal pro-brain natriuretic peptide levels were measured for all subjects. RESULTS: Lower cardiac output, stroke volume, maximal work, chronotropic index, maximal oxygen uptake, and higher N-terminal pro-brain natriuretic peptide levels were observed in the Fontan group than in the control group (p < 0.05). A negative correlation was found between physical exercise parameters and N-terminal pro-brain natriuretic peptide levels and dyssynchrony measurements. CONCLUSION: Measurements of exercise capacity, serum N-terminal pro-brain natriuretic peptide levels, and dyssynchrony measurement were more valuable than conventional methods for assessing patients' clinical and functional status. Dyssynchrony measurements provided better information about ventricular status than did conventional echocardiography studies. While patients' systolic function determined by conventional echocardiography was normal, dyssynchrony measurements showed the opposite result. The negative relationship between serum N-terminal pro-brain natriuretic peptide levels, dyssynchrony measurements, and exercise capacity suggests that these parameters should be investigated further in Fontan patients.

New approach in stage 1 surgery for hypoplastic left heart syndrome: preliminary outcomes.

OBJECTIVES: We present the short-term results of an alternative method in stage 1 surgery for hypoplastic left heart syndrome. METHODS: Data of 16 consecutive patients who were treated with the novel method in our clinic between February 2019 and March 2021 were analysed retrospectively. Preoperative data and postoperative follow-up were recorded. RESULTS: Of the 16 operated patients, 12 were diagnosed with hypoplastic left heart syndrome, while four were diagnosed with hypoplastic left heart syndrome variants. Seven patients died during early postoperative period. One patient died at home waiting stage 2 surgery. Three patient underwent stage 2 surgery. Pulmonary artery reconstruction was performed in one patient due to left pulmonary artery distortion. CONCLUSIONS: We believe that our method can be an effective alternative in the surgery of hypoplastic left heart syndrome and its variants. It is hoped that with increasing number of studies and more experience better outcome will be achieved.

Pleuropericardial Window Prevents Pericardial Effusion Following Surgical Atrial Septal Defect Closure.

BACKGROUND: Pericardial effusion occurs frequently after surgical atrial septal defect closure. This complication carries the risk of development of cardiac tamponade and death. It is also the responsibility of the hospital for readmissions. Any measure in preventing the development of pericardial effusion is of paramount importance. In this report, our objective was to demonstrate the protective effect of creating a pleuropericardial window against the development of postsurgical pericardial effusion. METHODS: Hospital records of all patients who underwent surgical atrial septal defect closure between January 2015 and December 2020 were reviewed. Patients were divided into 2 groups according to the creation of right/left pleuropericardial window during surgical ASD closure. There were 45 patients in group I in which a right pleuropericardial window was done, and 85 patients constituted group II in which pericardium was left intact. RESULTS: None of the 45 patients in group I developed pericardial effusion, while 15 of 85 patients in group II developed pericardial effusion (P=.001). Ten patients developed more than mild pericardial effusion which required medical treatment, while 5 patients had to be re-hospitalized because of massive pericardial effusion and effusions were managed by percutaneous drainage. CONCLUSIONS: The creation of a right pleuropericardial window resulted in a safe postoperative recovery after surgical atrial septal defect closure in all patients with the development of no pericardial effusion. No adverse effect of the creation of a pleural communication was noted.

Use of Parathyroid Function Index and Wisconsin Index to Differentiate Primary Hyperparathyroidism From Secondary Hyperparathyroidism: A Case-Control Study.

INTRODUCTION: Patients with primary hyperparathyroidism (PHPT) can be asymptomatic or have a normal calcium level (NHPT). Patients with 25(OH) vitamin D insufficiency, on the other hand, may present with a similar presentation. In regions where 25(OH) vitamin D deficiency is common, patients are usually diagnosed with secondary hyperparathyroidism (SHPT). Therefore, it is necessary to separate PHPT and NHPT from SHPT. Parathormone and calcium values are used for differentiation in the clinic. The predictive value of the newly developed parathyroid function test (PFindex), which previously had a high diagnostic value, was evaluated in this patient population in our investigation. METHODS: The study comprised 163 PHPT and NHPT patients with pathological confirmation and 56 SHPT patients. The PHPT, NHPT, and SHPT properties were defined using PFindex. The diagnostic power of PFindex was investigated using a receiver operating characteristic (ROC) curve of the results assessed in three groups. RESULTS: The PHPT group had the highest PFindex (1365.4±784.6) compared to the other two groups (NHPT: 723.5±509.4; SHPT:227.2±49.9, all p < 0.001). A PFindex threshold of 327.8 yielded 91.9% and 90.9% sensitivity and specificity rates for distinguishing PHPT and NHPT from SHPT, respectively. CONCLUSION: PFindex gave the outstanding diagnostic capacity to distinguish PHPT from SHPT due to our research. This straightforward tool can assist in making quick decisions about vitamin D therapy or surgery for PHPT.

Evaluation of acute kidney injury after surgery for congenital heart disease in neonates: a tertiary hospital experience.

PURPOSE OF THE ARTICLE: Acute kidney injury (AKI) after cardiac surgery in children with congenital heart disease (CHD) is a serious complication closely associated with high morbidity and mortality. Despite numerous studies on AKI in children, most studies have excluded neonates. We sought to characterize AKI associated with cardiac surgery in neonates, determine its incidence, perioperative and postoperative risk factors, and short-term results. MATERIALS AND METHODS: This retrospective study included 177 neonates who were operated on for CHD in our hospital between January 2015 and December 2019. Data of the patients were analyzed according to nKDIGO (neonatal Kidney Disease Improving Global Outcomes) and nRIFLE (neonatal Risk, Injury, Failure, Loss of function, End-stage kidney disease) criteria for evaluating AKI retrospectively. Data of groups with and without AKI were analyzed. RESULTS: The average age of 177 neonates were 8.2 ± 6.1 (1-28) days. Twenty-two (12.4%) neonates had CS-AKI defined according to nKDIGO criteria. Four (2.3%) neonates reached nKDIGO stage I, 1 (0.6%) reached stage II, 17 (9.6%) reached stage III. Thirty-eight (21.5%) neonates had CS-AKI defined according to nRIFLE criteria. Twenty-four (13.6%) neonates reached nRIFLE stage risk(R), 6 (3.4%) reached stage injury(I), 8 (4.5%) reached stage failure (F). The incidence of cardiac surgery-associated acute kidney injury (CS-AKI) in neonates was 12.5% and 21.5% for nKDIGO and nRIFLE, respectively. The percentage difference between nKDIGO and nRIFLE for AKI assessment was due to the criteria for nRIFLE stage risk(R) urine output < 1.5 mL/kg/h for 24 h. In both classifications, the duration of cardiopulmonary bypass, operation, inotropic treatment, and mechanical ventilation, length of intensive care unit (ICU), and hospital stay were significantly higher in the AKI group than those without AKI group (p˂.05). The mortality rate in the groups with AKI was found to be significantly higher (p˂.05) than in the groups without AKI. In Kappa analysis, when two classifications were compared according to AKI stages, a significant agreement was found between nKDIGO and nRIFLE classifications (p˂.05) (Kappa: 0.299). CONCLUSION: AKI and mortality rates were similar between groups according to the nKDIGO and nRIFLE criteria. For early prediction of AKI and adverse outcomes, diagnostic reference intervals might be specified in more detail in neonates undergoing cardiac surgery for CHD.

Neurologic Complications After Pediatric Heart Transplant: A Single-Center Experience.

OBJECTIVES: Neurologic complications that can lead to serious mortality and morbidity in pediatric heart transplant recipients have been reported to range from 23.6% to 45%. In this study, the frequency, time, cause, and characteristics of neurologic complications in pediatric heart transplant recipients were evaluated. MATERIALS AND METHODS: We retrospectively reviewed data of 37 pediatric heart transplant recipients aged <18 years who were seen at our hospital between 2007 and 2017. Medical records were reviewed to identify neurologic complications. Clinical features were compared between pediatric heart transplant patients with and without neurologic complications. RESULTS: The rate of posttransplant neurologic complications in pediatric heart transplant was 27% (10/37). Median age of patients with neurologic complications was 12 years (range, 11-18 years). Median time for neurologic complications was 3 days (range, 2-46 days). Primary diagnoses of these 10 recipients were dilated cardiomyopathy (n = 7) and restrictive cardiomyopathy (n = 3). There were no significant differences between recipients with and without neurologic complications (P > .05).The etiologies of neurologic complications were posterior reversible encephalopathy syndrome in 3 patients (8.1%), stroke in 2 patients (5.4%), peripheral neuropathy in 2 patients (5.4%), hypertensive encephalopathy in 1 patient (2.7%), and drug encephalopathy in 1 patient (2.7%). CONCLUSIONS: Neurologic complications may lead to serious mortality and morbidity in pediatric heart transplant patients. Seizures, posterior reversible encephalopathy syndrome, stroke, peripheral neuropathy, transient ischemic attack, and cerebral infections are the most common neurologic complications, which are seen in the perioperative period in particular. Careful follow-up of pediatric heart transplant patients, with detection and early treatment of neurologic findings, will contribute to lower rates of sequelae. To our knowledge, this is the largest study to show a detailed experience of neurologic complications in pediatric heart transplant patients from a single center in Turkey.

Results of balloon and surgical valvuloplasty in congenital aortic valve stenosis: A 19-year, single-center, retrospective study.

BACKGROUND: This study aims to compare the success, complications, and long-term outcomes of aortic balloon valvuloplasty and surgical aortic valvuloplasty in pediatric patients with congenital aortic valve stenosis. METHODS: Between March 2000 and October 2019, a total of 267 procedures, including 238 balloon valvuloplasties and 29 surgical valvuloplasties, in 198 children (135 males, 63 females; mean age: 57.4±62.6 months; range, 0.03 to 219 months) were retrospectively analyzed. The hospital records, echocardiographic images, catheterization data, angiography images, and operative data were reviewed. RESULTS: Aortic regurgitation was mild in 73 patients before balloon valvuloplasty, and none of the patients had moderate-to-severe aortic regurgitation. Compared to surgical valvuloplasty, the rate of increase in the aortic regurgitation after balloon valvuloplasty was significantly higher (p=0.012). The patients who underwent balloon valvuloplasty did not need reintervention for a mean period of 46±45.6 months, whereas this period was significantly longer in those who underwent surgical valvuloplasty (mean 80.5±53.9 months) (p=0.018). The overall failure rate was 8%. Moderate-to-severe aortic regurgitation was the most important complication developing due to balloon valvuloplasty in the early period (13%). All surgical valvuloplasties were successful. The mean length of hospitalization after balloon valvuloplasty was significantly shorter than surgical valvuloplasty (p=0.026). During follow-up, a total of 168 patients continued their follow-up, and a reinterventional or surgical intervention was not needed in 78 patients (47%). CONCLUSION: Aortic balloon valvuloplasty can be repeated safely and helps to eliminate aortic valve stenosis without needing sternotomy. Surgical valvuloplasty can be successfully performed in patients in whom the expected benefit from aortic balloon valvuloplasty is not achieved.

Analysis of Risk Factors for Rectus Sheath Hematoma.

OBJECTIVE: To evaluate the risk factors for developing rectus sheath hematoma (RSH). STUDY DESIGN: An observational study. PLACE AND DURATION OF STUDY: Department of General Surgery, Hitit University School of Medicine, Erol Olcok Training and Research Hospital, Turkey; from January 2018 to April 2020. METHODOLOGY: Patients with RSH were studied. Those with other pathologies in rectus sheath, and repeat studies, were excluded. Demographic data, presenting symptoms, comorbidities, medications administered containing anticoagulant drugs, imaging results, laboratory findings, coagulation parameters, length of hospital stay, treatments administered, type of RSH, morbidity, mortality and risk factors of increased bleeding diathesis, were recorded. RESULTS: Of the 61 studied patients, 56 (91.8%) had at least one chronic disease, and 77% were receiving anticoagulation therapy. RSH size was significantly larger for patients taking acetylsalicylic acid than for patients taking other anticoagulants, and an RSH area less than 1,924 mm2 was associated with increased length of hospital stay. Binary logistic regression analysis showed that a unit increase in gender was associated with a 1.5-fold increase in the risk of greater RSH size, and that female gender was associated with a 45.3-fold risk of increase in the risk of RSH. Notably, if up to 4 units of erythrocyte suspension replacement is not applied for conservative treatment of RSH, RSH size may increase by 23.5 times. CONCLUSION: Risk factors of RSH include chronic obstructive pulmonary disease, congestive heart failure, coronary artery disease, atrial fibrillation, asthma, hypertension, diabetes mellitus, chronic renal failure, prior abdominal surgery, female sex, older age, anticoagulant drug use and cancer-related immunosuppression. Key Words: Rectus sheath hematoma, Conservative treatment, Anticoagulant treatment.

The Effect of L-Hook Dissection and Scissors Dissection on Liver Injury in Laparoscopic Cholecystectomies.

PURPOSE: Laparoscopic cholecystectomy is generally performed with the help of monopolar cautery. We aimed to reveal the effect of monopolar cautery use on liver damage in this study. METHOD: Data of patients who underwent elective cholecystectomy between January 2016 and April 2020 were collected retrospectively. The patients were divided into two groups according to the surgical technique as hook dissection (HD) and scissor dissection (SD). The amount of increase in the preoperative and postoperative alanine aminotransferase (ALT) and aspartate aminotransferase (AST) values of the patients was compared between the two groups. FINDINGS: Over 970 patients were included in the study. The changes in pre-post ALT and AST values were statistically significantly different between the HD (n=469) and SD (n=501) groups (p<0.001; p0.001). ALT (26 (-25, 338)) and AST (27 (-23, 444)) changes in the HD method were statistically significantly higher than ALT (11 (-16, 371)) and AST (10.8 (-37, 617)) changes in the SD method. RESULTS: ALT and AST values increase after all laparoscopic cholecystectomies. Although the increase in ALT and AST in the HD patients is statistically significant when compared to the SD group, both methods of laparoscopic cholecystectomy can be safely performed because they do not cause permanent liver injury.

First Harvest of Pediatric and Congenital Heart Surgery Multicenter Database in Turkey: Novel Application of Real-Time Online Reporting.

OBJECTIVES: A new congenital heart surgery database (CKCV) with real-time online reporting function was recently developed in Turkey. All standard international parameters were used, but Aristotle Comprehensive Complexity score was modified. In this study, the first analysis of the CKCV Database is reported. METHODS: The CKCV Database included 2307 procedures from 12 centers between January 2018 and March 2020. All parameters, including 10 real-time online reports, which represent the number of centers, number and mortality rates of all procedures, number of extracorporeal membrane oxygenation (ECMO) and results, details of postoperative complications, age-group statistics, analysis for priority status, mean intensive care and hospital stay durations of the procedures, results of Aristotle Basic, Modified Aristotle Comprehensive (MACC) and Society of Thoracic Surgeons-European Association (STAT) Score Categories, comparison of centers were analyzed. RESULTS: Most common 10 procedures were ventricular septal defect (VSD) repair (n = 273), tetralogy of Fallot (TOF) repair (n = 243), atrial septal defect (ASD) repair (n = 181), complete AVSD repair (n = 95), cavopulmonary anastomosis (n = 81), systemic to pulmonary shunt (n = 79), modified Fontan (n = 71), subaortic resection, (n = 66) PA banding (n = 66), and arterial switch operation (n = 66). Cardiopulmonary bypass was used in 84.6% of the procedures. Overall mortality rate was 6.0%. A total of 618 major and 570 minor complications were observed in 333 and 412 patients, respectively. According to six MACC categories, number of the patients and mortality rates were I (293; 0.3%); II (713; 1.4%); III (601; 3.3%); IV (607; 12%); V (84; 35.7%); and VI (9; 55.6%), respectively. Analysis of five STAT Categories showed 0.7, 3.8, 5.4, 14.9, and 54.7% mortality rates. CONCLUSIONS: CKCV Database has a great potential for nationwide quality improvement studies. Users could instantly analyze and compare their results to national and international aggregate data using a real-time online reporting function. This is the first multicenter congenital database study in Turkey.

Sternotomy with electrocautery and sternal wound infection in congenital heart surgery in patients under 1 year of age.

OBJECTIVE: The present study aimed to compare the rate of wound site infection in patients <1 year of age who underwent sternotomy using electrocautery, a routinely performed procedure in our clinic, with those reported in the literature. METHODS: This double-center study included patients <1 year of age who underwent cardiac surgery via sternotomy performed with electrocautery for congenital heart disease between January 2017 and June 2019. Patient's data were retrospectively obtained from the hospital records. RESULTS: In our study, seven patients developed SSI, which was superficial in six (1.3%) patients and in the form of mediastinitis in one (0.2%) patient. CONCLUSION: Sternotomy with electrocautery, which we consider an easy and safe method, was also not found to be statistically different from the other methods in terms of SWI.

Infective endocarditis in childhood: a single-center experience of 18 years

Abstract Introduction: We aimed to present the risk factors, clinical and laboratory findings, treatment management, and risk factors for morbidity and mortality of infective endocarditis (IE) as well as to relate experiences at our center. Method: We retrospectively analyzed data of 47 episodes in 45 patients diagnosed with definite/possible IE according to the modified Duke criteria between May 2000 and March 2018. Results: The mean age of all patients at the time of diagnosis was 7.6±4.7 years (range: 2.4 months to 16 years). The most common symptoms and findings were fever (89.3%), leukocytosis (80.8%), splenomegaly (70.2%), and a new heart murmur or changing of pre-existing murmur (68%). Streptococcus viridans (19.1%), Staphylococcus aureus (14.8%), and coagulase-negative Staphylococci (10.6%) were the most commonly isolated agents. IE-related complications developed in 27.6% of the patients and the mortality rate was 14.8%. Conclusion: We found that congenital heart disease remains a significant risk factor for IE. The highest risk groups included operated patients who had conduits in the pulmonary position and unoperated patients with a large ventricular septal defect. Surgical intervention was required in most of the patients. Mortality rate was high, especially in patients infected with S. aureus, although the time between the onset of the first symptom and diagnosis was short. Patients with fever and a high risk of IE should be carefully examined for IE, and evaluation in favor of IE until proven otherwise will be more accurate. In high-risk patients with prolonged fever, IE should be considered in the differential diagnosis.
