(2015) Ince, Emine; Oguzkurt, Pelin; Gezer, Hasan Ozkan; Aliskan, Hikmet Eda; Hicsonmez, Akgun; 0000-0001-9060-3195; 27735804; AAE-2282-2021; J-3197-2013
Myiasis is a rare condition caused by the invasion of tissues by the larvae of flies. Many cases of myiasis involving various human organs have been reported. Tracheopulmonary or intratracheal myiasis is a very unusual and aberrant form of the disease in humans. We present a case of respiratory myiasis after aspiration of larvae by a healthy 8-month-old girl, which cannot be found in the English literature.
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-4719-2018
Background/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.

Huge Neck Masses Causing Respiratory Distress in Neonates: Two Cases of Congenital Cervical Teratoma
(2016) Gezer, Hasan Ozkan; Oguzkurt, Pelin; Temiz, Abdulkerim; Bolat, Filiz Aka; Hicsonmez, Akgun; 0000-0002-4635-2613; 0000-0001-8789-6003; 25176284; J-3197-2013; A-4719-2018
Congenital cervical teratomas are rare and usually large enough to cause respiratory distress in the neonatal period. We present two cases of congenital huge cystic neck masses in which distinguishing cervical cystic hygroma and congenital cystic teratoma was not possible through radiologic imaging techniques. Experience with the first case, which was initially diagnosed and treated as cystic hygroma by injection sclerotherapy, led to early suspicion and surgery in the second case. The masses were excised completely and histopathologic diagnoses were congenital teratoma in both patients. Our aim is to review congenital huge neck masses causing respiratory distress in early neonatal life to highlight this dilemma briefly with these interesting cases.

Intestinal Malrotation Needs Immediate Consideration and Investigation
(2016) Ezer, Semire Serin; Oguzkurt, Pelin; Temiz, Abdulkerim; Ince, Emine; Gezer, Hasan Ozkan; Demir, Senay; Hicsonmez, Akgun; 0000-0002-4209-9075; 0000-0001-8789-6003; 0000-0002-4635-2613; 0000-0002-9597-3264; 27353636; AAK-9310-2021; J-3197-2013; AAJ-9529-2021; A-4719-2018
BackgroundThe aim of this study was to evaluate clinical presentation, diagnostic studies, and volvulus rate and to describe the unusual clinical clues of intestinal malrotation. 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.
Pancreatic Tumors in Children
(2021) Gezer, Hasan Ozkan; Temiz, Abdulkerim; Ezer, Semire; Yazici, Nalan; Demir, Senay; Hasbay, Bermal; Oguzkurt, Pelin; 0000-0002-4635-2613; 0000-0002-4209-9075; 0000-0001-6702-7265; A-4719-2018; AAJ-9529-2021; AAM-5138-2021; AAK-9310-2021
Objective: Pancreatic rumors in children are exceedingly rare and hence present diagnostic and therapeutic challenges to pediatric surgeons. In this study, we aimed to present our experiences and treatment outcomes related to these rare tumors. Methods: The clinical data, laboratory investigations, radiological imaging, and the pathology and surgical details of patients with pancreatic tumors who were diagnosed between 2005 and 2019 were retrospectively reviewed. Results: A total of 9 patients (5 men) were included in the study. The most common symptom at the time of presentation was vague abdominal pain. A pancreatic rumor was detected incidentally in 4 patients. All tumors were non-functional primary rumors. Histopathological diagnosis of these tumors were solid-pseudopapillary tumors (n=3), congenital pancreatic cysts (n=3), pancreatoblastoma (n=1), rhabdomyosarcoma (n=1), and an undifferentiated carcinoma (n=1). In addition, 8 patients were treated surgically (through tumor excision, central pancreatectomy + distal pancreaticojejunostomy, distal pancreatectomy, and cystogastrostomy). Two deaths from tumor dissemination were recorded. The patients were followed-up at a mean duration of 72 months (range: 6-120 months). Conclusion: Pediatric pancreatic tumors arc rare and are usually benign in nature. They present symptoms that are often nonspecific. In non-metastatic cases, surgical tumor removal is the preferred method for the treatment. For most tumors, surgical resection is the optimal treatment that may be successfully performed with low morbidity rate when the lesion is either in the body or in the tail of the pancreas. The long-term outcomes with this approach are generally good.

(2014) Gezer, Hasan Ozkan; Oguzkurt, Pelin; Temiz, Abdulkerim; Demir, Senay; Hicsonmez, Akgun; https://orcid.org/0000-0002-4635-2613; https://orcid.org/0000-0001-8789-6003; https://orcid.org/0000-0002-4209-9075; 25341605; J-3197-2013; A-4719-2018; AAK-9310-2021
An aneurysmal bone cyst (ABC) is a benign but often rapidly expanding osteolytic multi-cystic osseous lesion that occurs as a primary, secondary, intra-osseous, extra-osseous, solid, or conventional lesion. A 15-year-old boy presented with a left-sided intrathoracic mass displacing the lung without bone destruction. The mass was totally resected without rib resection, and the pathological diagnosis was ABC. The clinical manifestations, etiology, management, and pathology are discussed, with a brief discussion regarding the difficulty in the preoperative differential diagnosis.
Spleen Salvaging Treatment Approaches in Non-parasitic Splenic Cysts in Childhood
(2016) Gezer, Hasan Ozkan; Oguzkurt, Pelin; Temiz, Abdulkerim; Ince, Emine; Ezer, Semire Serin; Kocer, Nazim Emrah; Demir, Senay; Hicsonmez, Akgün; 27574347
The aim of this study was to evaluate our experience with primary non-parasitic splenic cysts (NPSC) which are relatively rare in children and consist almost exclusively of single case reports or small case series in the literature. The medical records of all patients who presented to our clinic with NPSC between 2005 and 2015 were evaluated retrospectively. There were 22 children whose ages ranged from 2 months to 14 years (mean 9.2 +/- 4.7 years). The size of the cysts was in the range of 5 to 200 mm (mean 55.4 +/- 48.2 mm). Ten patients underwent surgery for splenic cysts. Partial splenectomy (n = 2), total cyst excision (either open n = 4 or laparoscopically n = 1), and total splenectomy (n = 3) were performed. The non-operated patients were asymptomatic and followed with ultrasound (US). The follow-up period in non-operated patients ranged from 6 months to 5 years (mean 2.27 +/- 1.29 years). Complete regression was observed in four (33 %) non-operated patients. The regressed cyst measurements were 10, 16, 30, and 40 mm, respectively. Approximately half of the NPSC is diagnosed incidentally. Small (< 5 cm) asymptomatic cysts should be under regular follow-up with US/physical examination for regression. If surgery is required, we prefer open cyst excision as it gives excellent results and preserves splenic immune function.
Variations in apparent diffusion coefficient values following chemotherapy in pediatric neuroblastoma
(2015) Demir, Senay; Altinkaya, Naime; Kocer, Nazim Emrah; Erbay, Ayse; Oguzkurt, Pelin; 25519453
PURPOSE In children the assessment of solid tumors' response to chemotherapy is based primarily on size reduction, which can be unreliable and a late marker, in the presence of necrosis. We aimed to establish whether apparent diffusion coefficient (ADC) values of childhood neuroblastomas show proportional changes in relation to chemotherapy response. METHODS We evaluated 15 pediatric patients with abdominopelvic neuroblastomas, who had undergone MRI before and after chemotherapy. Two radiologists retrospectively analyzed all images by drawing a round uniform region-of-interest in the solid/contrast-enhancing portion of the lesions in consensus. The ADC values from pre- and postchemotherapy images were compared. RESULTS Postchemotherapy ADC values were significantly higher than those obtained before treatment (P < 0.05, for minimum, maximum, and median ADC values). CONCLUSION Our results support diffusion-weighted MRI as a promising noninvasive biomarker of therapeutic responses. To the best of our knowledge, this is the first report to compare diffusion-weighted imaging findings before and after chemotherapy in childhood neuroblastic tumors.
