Item Urinary Ngal, Kim-1 and L-fabp Levels in Antenatal Hydronephrosis(2014) Dursun, Hasan; Noyan, Aytul; Parmaksiz, Gonul; Ezer, Semire Serin; Anarat, Ruksan; Cengiz, Nurcan; https://orcid.org/0000-0002-8817-494X; https://orcid.org/0000-0003-2373-1837; AAW-8783-2020; AAD-5713-2021; AAM-2935-2021; AAJ-9529-2021Item Urinary NGAL, KIM-1 and L-FABP Concentrations in Antenatal Hydronephrosis(2015) Noyan, Aytul; Parmaksiz, Gonul; Dursun, Hasan; Ezer, Semire Serin; Anarat, Ruksan; Cengiz, Nurcan; 0000-0002-8817-494X; 0000-0003-2373-1837; 0000-0002-9597-3264; 26096437; AAJ-9529-2021; AAB-7105-2020; AAD-5713-2021; AAW-8783-2020; GPX-7059-2022; AAM-2935-2021The clinical tests currently in use for obstructive nephropathy (such as renal ultrasonography, differential radionuclide renal scans and urinary creatinine concentration data) are not efficient predictors of the subsequent clinical course. Novel and simple biomarkers are required which, if proven, could be clinically beneficial in determining if a patient is eligible for surgery or reno-protective therapy. More recently, the interest of clinicians has focused on the potential of urinary neutrophil gelatinase-associated lipocalin (uNGAL), urinary kidney injury molecule-1 (uKIM-1) and urinary liver-type fatty acid-binding proteins (uL-FABP) as biomarkers for renal function in children with hydronephrosis (HN). Objective The purpose of this study was to investigate possible clinical applications of uNGAL, uKIM-1 and uL-FABP as beneficial non-invasive biomarkers to determine whether or not surgical intervention is required in children with HN. Study design Renal ultrasonography and radionuclide renal scans were used as diagnostic tools to detect HN. Patients were divided into two groups based on the anteroposterior diameter of their renal pelvis and the presence of dysfunction. Group 1 included 26 children with severe HN (with dysfunction), and group 2 consisted of 36 children with mild HN (without dysfunction). Urine samples were collected from 62 children with HN and 20 healthy children. Results Hydronephrosis was more common in males than in females, with a male to female ratio of 9: 1 in the study sample. The incidence of left kidney involvement (32 patients) was slightly higher than right kidney involvement (28 patients). Compared with controls and group 2, the ratio of uNGAL to creatinine was significantly higher in group 1 (p < 0.05). The biomarker uNGAL/Cr exhibited fairly good diagnostic accuracy, with an area under the curve of 0.68 [95% confidence interval 0.6-0.7] and an optimal cut-off value of 0.16 ng/mg Cr (sensitivity 58%, specificity 75%) (p < 0.05). There was a positive correlation between the uNGAL/Cr ratio and the uKIM-1/Cr ratio (r = 0.582, p < 0.05) and uL-FABP/Cr ratio (r = 0675, p < 0.05) in group 1. Discussion The results clearly demonstrated that children with hydronephrosis and dysfunction had significantly increased uNGAL, and uNGAL/Cr concentrations. However, uKIM-1, uKIM-1/Cr, uL-FABP and uL-FABP/Cr concentrations were not significantly different when compared with controls. These results support the use of uNGAL concentrations as an early marker for renal dysfunction in HN. Conclusions The study clearly demonstrated that pediatric patients with hydronephrosis and dysfunction had significantly higher uNGAL to creatinine concentrations as compared with controls.Item Choledochal Cysts in Children: Intrahepatic Ductal Dilatation Does Not Indicate True Intrahepatic Biliary Duct Disease(2016) Gezer, Hasan Ozkan; Oguzkurt, Pelin; Ince, Emine; Ezer, Semire Serin; Temiz, Abdulkerim; Hicsonmez, Akgun; https://orcid.org/0000-0002-9597-3264; https://orcid.org/0000-0001-8789-6003; 26620959; J-3197-2013; A-4719-2018Background/Aims: Choledochal cysts (CCs) are rare abnormalities of the biliary tract. Presenting our clinical experience with CCs herein, we aimed to identify if intrahepatic ductal dilatation indicates true intrahepatic biliary duct disease. Materials and Methods: We retrospectively reviewed all cases of CCs in children diagnosed at a single center (Baskent University Faculty of Medicine, Department of Pediatric Surgery) institution from 2005 to 2015. Results: Of 18 patients with CCs, 7 were males (39%). The age range was 3 months to 17 years (mean age, 6.2 +/- 3.8 years). Intrahepatic bile duct dilatation was detected in 13 (72%) patients by preoperative scanning. Type I, II, III, and IVA cysts were diagnosed in 13, 1, 1, and 3 patients, respectively. In all patients, total cyst excision and Roux-en-Y hepaticoenterostomy were performed. Conclusion: In this study, most intrahepatic ductal dilatations seen on preoperative imaging were thought to be caused by a distal obstruction, not true intrahepatic biliary duct disease. This study supports the hypothesis that preoperatively distinguishing between type I and type IVA CCs is not necessary; it does not affect the initial treatment. We consider that complete cyst excision with Roux-en-Y hepaticojejunostomy is safe and should be performed soon after diagnosis, irrespective of symptom severity to avoid future complications.Item Meckel Diverticulum in Children: Evaluation of Macroscopic Appearance for Guidance in Subsequent Surgery(2016) Gezer, Hasan Ozkan; Temiz, Abdulkerim; Ince, Emine; Ezer, Semire Serin; Hasbay, Bermal; Hicsonmez, Akgun; 0000-0002-4635-2613; 0000-0001-8789-6003; 0000-0002-9597-3264; 26435520; J-3197-2013; A-4719-2018; AAJ-9529-2021Background: The treatment of incidentally encountered asymptomatic Meckel diverticulum(MD) is controversial. We evaluated whether the macroscopic appearance correlates with clinical features, histopathological findings, future complications, and management decisions. Methods: Patients who underwent MD resection at a single institution from 2000 to 2012 were retrospectively analyzed in terms of age, sex, clinical features, laboratory data, perioperative findings (diverticulum length, diameter, depth, thickening, and height-to diameter ratio [HDR]), pathology, and postoperative follow-up. Results: Fifty children were enrolled. Sixteen percent of the resected MDs were found incidentally. Of 42 complicated MDs, 17 (40%) were long (HDR >= 2), 14 (33%) were thickened, and 29 (70%) exhibited base widening. Histopathologically, ectopic mucosa was found in 32 (64%) of all MDs and in 5 (62%) of incidentally removed MDs. There was no statistical difference between the macroscopic appearance and clinical signs, sex, or presence of ectopic tissue based on palpation. Conclusion: The macroscopic appearance of MD does not indicate the presence or absence of HGM and cannot be used to guide subsequent surgery. Additionally, 40% of symptomatic patients in our study had life-threatening complications requiring prompt fluid resuscitation. We consider that incidentally detected MD should be removed regardless of its macroscopic appearance. (C) 2016 Elsevier Inc.

MethodsA retrospective descriptive review was carried out of all patients diagnosed with intestinal malrotation between 2002 and 2014. Patients were divided into two groups: infants (1year, n=16; group 1); and children (>1year, n=12; group 2). Patient demographics, clinical history, symptoms, physical examination, diagnostic work-up, operative findings and early outcome were evaluated. ResultsBilious vomiting was the cardinal complaint in both groups. Unusual symptoms such as respiratory insufficiency, dehydration, afebrile convulsion, and lethargy were prominent symptoms in six patients in group 1, whereas history of frequent hospitalization due to recurrent abdominal pain and feeding intolerance were prominent in six patients in group 2. Midgut volvulus was identified in 15 patients, four of whom were in group 2. Standard Ladd's procedure was done in addition to correction of volvulus. ConclusionMalrotation with or without midgut volvulus is not a rare condition and should be kept in mind for any age group. Specific signs of diagnosis are not easily identified. In the case of unusual clinical presentation, diagnosis may be delayed and can result in catastrophic consequences if intestinal perfusion occurs. Although midgut volvulus is seen most frequently in infants, risk and complication rate are high beyond 1year of age as well, and can manifest as failure to thrive, food intolerance, and abdominal pain needing recurrent hospitalization. Diagnostic suspicion and interdisciplinary coordination are essential for timely diagnosis and surgical treatment.Item Bronchopulmonary Foregut Malformation: Continuity of Pulmonary Sequestration and Distal Esophagus(2018) Ezer, Semire Serin; Abdulkerim, Temiz; Senay, Demir; Bermal, Hasbay; 30060803; AAJ-9529-2021Item Management of Traumatic Bile Duct Injuries in Children(2018) Temiz, Abdulkerim; Ezer, Semire Serin; Gedikoglu, Murat; Serin, Ender; Ince, Emine; Gezer, Hasan Ozkan; Canan, Mehmet Oguz; Hicsonmez, Akgun; https://orcid.org/0000-0001-8789-6003; https://orcid.org/0000-0002-9597-3264; https://orcid.org/0000-0002-0138-6107; https://orcid.org/0000-0002-4635-2613; https://orcid.org/0000-0003-0614-4497; 29948144; A-4719-2018; AAJ-9529-2021; AAM-7281-2021; J-3197-2013; AAI-9386-2021Pediatric experience with biliary tract injuries (BTI) is limited and mostly consists of case presentations. The purpose of this study is to evaluate clinical and radiological findings of possible BTI, treatment strategies, and results. The records of nine patients with the diagnosis of BTI between July 2009 and November 2017 were reviewed retrospectively. There were seven boys and two girls (mean 8.05 +/- 4.39 years). The mechanisms were motor vehicle occupant, fall, crush and gunshot wound. Hepatic laceration routes that extended into the porta hepatis and contracted the gall bladder were demonstrated on computerized tomography (CT). Bile duct injury was diagnosed with bile leakage from the thoracic tube (n = 2), from the abdominal drain (n = 2) and by paracentesis (n = 5). Extrahepatic (n = 8) and intrahepatic (n = 1) bile duct injuries were diagnosed by cholangiography. Endoscopic retrograde cholangiography, sphincterotomy, and stent placement were successfully completed in five patients. Peritoneal drainage stopped after 3-17 days of procedure in four patients. The fifth patient was operated with the diagnosis of cystic duct avulsion. Cholecystectomies, primary repair of laceration, cystic duct ligation, and Roux-en-Y hepatoportoenterostomy were performed in the remaining four patients. All patients presented with clinically normal findings, normal liver functions, and normal ultrasonographic findings in the follow-up period. The presentation of the parenchymal injury extending to the porta hepatis with contracted gall bladder on CT and diffuse homogenous abdominal fluid should be considered as signs of BTI. We suggest a multi-disciplinary approach for the diagnosis and treatment of BTIs. Surgery may be indicated according to the patient's clinical condition, radiological findings and failure of non-operative treatment.Item Ingested foreign bodies in children: Do they really pass spontaneously from the gastrointestinal tract? A single-centre experience with 1000 cases(2020) Gezer, Hasan Ozkan; Ezer, Semire Serin; Temiz, Abdulkerim; Ince, Emine; Hicsonmez, Akgun; 0000-0002-9597-3264; 0000-0002-4635-2613; 0000-0001-8789-6003; 32185763; AAJ-9529-2021; J-3197-2013; A-4719-2018BACKGROUND: Foreign body (FB) ingestion is frequently encountered in all departments that treat children. FB may bring about significant anxiety for parents and physicians. The present study aims to determine the appropriate approach for FB ingestion in children. METHODS: The records of 1000 children with a history of FB ingestion between the years 2005 and 2017 were reviewed retrospectively in this study. RESULTS: Of 1000 children, 53.8% were male. The most common types of FBs were coins (35%). X-ray was negative in 49% of the patients, and 86% of these patients received no intervention. Of the 504 (51%) X-ray-positive patients, the oesophagus (68%) was the most common location. Life-threatening complications were tracheo-oesophageal fistula (I), Meckel's diverticulum perforation (I), and perforation due to rigid endoscopy (I). CONCLUSION: We demonstrated that coins, which are the most commonly ingested FBs, have various types and sizes according to their countries of origin, and this affects spontaneous passage. We found that only 48% (quite low compared to the literature) of the coins passed spontaneously. In asymptomatic patients with a gastric button battery, we suggest a "watchful waiting" approach. The patients should be observed and managed at home. In our study, we found that 85% of the button batteries that reached the stomach passed spontaneously.Item Treatment of young patients with pilonidal sinus disease with the original (unmodified) Limberg flap standardized for the first time(2020) Gezer, Hasan Ozkan; Ezer, Semire Serin; Ince, Emine; Temiz, Abdulkerim; 0000-0002-9597-3264; 0000-0001-8789-6003; 0000-0002-4635-2613; 32353919; A-4719-2018; J-3197-2013; AAJ-9529-2021Background Pilonidal sinus disease (PSD) is commonly seen in young adults but may also affect adolescents. Our goal was to present results from operated patients, with a focus on the original Limberg flap, which we standardized for the first time. Methods This study was a retrospective review of 60 teenage patients who underwent surgery in a single pediatric surgery center over approximately 15 years. Results Of the 60 patients, 33 (55%) were male and the mean age was 14.20 +/- 1.31 (9-17) years. After pilonidal sinus excision, primary repair and Limberg flap were performed in 45 (75%) and 15 (25%) patients respectively. There were no complications in the patients who underwent the Limberg flap technique, whereas 49% of the patients who underwent primary repair exhibited complications. The mean follow-up was 6.7 +/- 4.8 years. Conclusion We standardized the Limberg flap for the first time in children with measurements and consider that it meets expectations: it is not difficult to perform, it has low complication and recurrence rates, it requires an acceptable period to return to normal activities, and gives satisfactory cosmetic results. We did not identify any complications in patients treated with the Limberg flap excision and post-operative epilation. We consider that findings achieved by the treatment of original, standardized Limberg flap excision is comparable with all of the treatment methods reported in the literature related with children.Item Gastroschisis Treatment: Evaluation of Surgical Techniques and Results(2020) Ince, Emine; Ezer, Semire Serin; Temiz, Abdulkerim; Gezer, Hasan Ozkan; Hicsonmez, Akgun; A-4719-2018; AAJ-9529-2021Objective: Recently, achieving good cosmetic results for patients with gastroschisis has gained popularity, as since the visceral organs can be safely positioned into the abdominal cavity. We aimed to evaluate patient outcomes while focusing on the cosmetic results to contribute to the limited amount of data on this subject in the literature. Methods: From January 2005 to May 2018, patients operated on for gastroschisis in a single institution were evaluated retrospectively. Results: Twenty-two patients with gastroschisis were treated (10 females/12 males). The mean gestational age was 38.2 +/- 2.1 weeks. The mean birth weight was 2256.9 +/- 418.2 g. Eleven patients were diagnosed prenatally. Five patients had complex gastroschisis. Others presented with necrosis (n=3), perforation (n=3), volvulus (n=1) and jejunal atresia (n=1). Primary closure (n=16) and staged closure (n=6) were performed. Patients needed mechanical ventilation and total parenteral nutrition for 3.7 +/- 1.0 days and 24.3 +/- 9.7 days, respectively. Enteral feeding was started at 15.9 +/- 10.5 days. The duration of hospitalisation was 36.7 +/- 13.3 days. Three patients died from sepsis and multi-organ failure. Conclusion: We believe that performing appropriate gastroschisis surgery at the same hospital without transferring to another centre is the main factor in achieving a successful outcome. Good cosmetic results and visceral function were achieved in this study in 86.3% patients.
