    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-9529-2021
    Background: 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. All rights reserved.

    Boix-Ochoa (Partial Fundoplication) Treats Reflux, Even in Neurologically Impaired Patients. Can it Take the Title of "Gold Standard" from Total Fundoplication?
    (2019) Gezer, Hasan Ozkan; Ezer, Semire Serin; Temiz, Abdulkerim; Ince, Emine; Hicsonmez, Akgun; 0000-0002-4635-2613; 30887292; J-3197-2013
    Background In 4-5% of cases of gastroesophageal reflux disease (GERD), surgical treatment is required. The aim of the study was to evaluate the success of Boix-Ochoa antireflux surgery, which is considered more physiologic with a higher failure rate (need for reoperation) than Nissen fundoplication, which is believed to be the gold standard operation. Method In the 13 years from 2005 to 2018, the medical records of all children who underwent Boix-Ochoa in a single institution by pediatric surgeons were reviewed retrospectively. Results A total of 133 fundoplications were performed, of which patients were divided into four groups: neurologically impaired, structurally impaired, neurologically and structurally impaired, and neurologically and structurally normal; there were 64, 8, 34, and 27 patients in each group, respectively. Structural impairments included hiatal hernia and esophagus atresia, having previously had a gastrostomy and esophageal stenosis. The most common short-term complication was distal esophageal stenosis (13%), which caused vomiting and dysphagia, and was treated by dilatations. There were six (4.5%) recurrences of GER, one in the neurologically and structurally impaired group with a hiatal hernia and five in the structurally impaired group (three esophagus atresias, two caustic esophageal strictures). The mean follow-up period was 5.27 +/- 3.43 years. Neurological impairment did not affect the success rate. Conclusion Although there has not any literature demonstrating significant benefits of one procedure, we detected with this largest study in the pediatric literature about Boix-Ochoa fundoplication (more physiologic and easily performed) that it was successful (95%) in protecting reflux even in neurologically impaired patients (98%). We consider Boix-Ochoa (partial fundoplication) to be an alternative method to Nissen (complete fundoplication), and it can be done safely with a high success rate.

    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.
