    AMAÇ: Çocukluk çağı morbid obezitesi özellikle gelişmiş ve gelişmekte olan ülkelerde son iki dekatta iki kat artış göstermiş olup tedavide bariatrik cerrahi etkili bir yöntem olarak uygulanmaktadır (1). Laparoskopik sleeve gastrektomi (LSG) günümüzde en sık uygulanan bariatrik cerrahi yöntemidir (1,2). Adölesan çağı obezitesinin tedavi yönetimi multidisipliner yaklaşım gerektirmektedir (3). Çalışmamızda, adölesan çağı obezitesinde uyguladığımız bariatrik cerrahi sonuçlarımızı göstermeyi amaçladık. YÖNTEM: Retrospektif olarak 2018-2021 yılları arasında Bezmialem Vakıf Üniversitesi Tıp Fakültesi Genel Cerrahi Anabilim Dalı’na bariatrik ve metabolik cerrahi uygulanan 634 hastadan; adölesan çağında (≤18 yaş) morbid obezite nedeniyle (VKİ≥40kg/m2), çocuk endokrinoloji ve çocuk psikiyatristi tarafından yönlendirilen ve LSG uygulanan 32 hasta çalışmaya dahil edildi. Hastaların demografik verileri (yaş, cins, ek hastalık, vücut kitle indeksi (VKİ), komorbid hastalıkları, ilaç kullanım öyküsü) incelendi. Postoperatif dönemde komplikasyon, fazla kilo kaybı oranları, komorbid hastalıkların remisyon durumu değerlendirildi. BULGULAR: Çalışmadaki toplam 32 hastanın ortalama yaşı 16,1±1,07 yıl idi. Hastaların 24’ü (%75) kız ve 8’i (%25) erkek idi. Preoperatif ortalama VKİ 47,4±7,56 kg/m2 idi. Hastaların 22’sinde (%66,6) tip 2 diyabet, 7’sinde (%21,8) hipertansiyon ve 4’ünde (%12,5) obstrüktif uyku apne sendromu vardı. Tüm hastalara LSG uygulandı. Ortalama ameliyat süresi 71,2±17,3 dakika ve yatış süresi 4,3±0,7 gün idi. Peroperatif ve postoperatif herhangi bir komplikasyon izlenmedi. Mortalite izlenmedi. Postoperatif takiplerinde ortalama % EWL değerleri 3.ayda %27,7, 6.ayda %48,05 ve 12.ayda %72,1 idi. Komorbid hastalıklardaki remisyon oranların tip 2 diyabet için %86,3, hipertansiyon için %71,4 ve obstrüktif uyku apne sendromu için %100 olarak saptandı. SONUÇ: Adölesan çağı obezitesinde endikasyona uygun olarak seçilmiş hastalarda LSG tekniği güvenli ve etkili bir tedavi yöntemidir. Anahtar Kelimeler: Adölesan, Obezite, Sleve Gastrektomi

    (2018-05-01) Gecer, Melin Ozgun; Bozkurt, Suleyman; Baskoy, Lutfullah; BEKTAŞOĞLU, HÜSEYİN KAZIM; YIĞMAN, SAMET; Akbulut, Huseyin; Coskun, Halil; YARDIMCI, ERKAN; BOZKURT, SÜLEYMAN; BAŞKÖY, LÜTFULLAH; BEKTAŞOĞLU, HÜSEYİN KAZIM; GEÇER, MELİN; YIĞMAN, SAMET; AKBULUT, HÜSEYİN
    Laparoscopic sleeve gastrectomy (LSG) is the most preferred technique in morbidly obese patients for weight loss. There is a controversy about the routine preoperative evaluation of the stomach and the routine microscopic examination of all LSG specimens. Our aim is to analyze the results of both preoperative upper gastrointestinal endoscopy and endoscopic biopsies and also the results of histopathological examination of LSG specimens.

    (2012-11-13) SARI, S; Aysan, E; MUSLUMANOGLU, M; ERSOY, YELİZ EMİNE; BEKTASOGLU, HÜSEYİN KAZIM; YARDıMCı, ERKAN; AYŞAN, MUSTAFA ERHAN; ERSOY, YELIZ EMINE; BEKTAŞOĞLU, HÜSEYİN KAZIM; YARDIMCI, ERKAN
    Background: We aimed to minimalize operative complications by spraying of methylene blue stain on thyroid glands and the perithyroidal area. Material and methods: The intra-operative methylene blue spraying technique was used prospectively on a total of 56 patients who had undergone primary (not recurrent) thyroid surgery for a variety of thyroid diseases. Bilateral total thyroidectomy was performed in all cases. After superior but before inferior pole ligation, 0.5ml of methylene blue was sprayed over the thyroid lobe and perilober area. Tissues, especially parathyroides, the recurrent laryngeal nerve, and the inferior thyroid artery, were identified and evaluated. Results: Recurrent laryngeal nerve and arteries were not stained and thus they remained white in all cases while all other tissues were stained blue. Within three minutes parathyroid glands washed out the blue stain and the original yellow color was regained. Thyroid tissue wash-out time was not less than 15 minutes; perithyroideal muscles, tendinous and lipoid structures took no less than 25 minutes. Conclusion: The safety of intravascular methylene blue guidance on thyroid surgery is known. This research demonstrates the effectiveness of the spraying technique, a new technique which ensures not only identification of parathyroid glands within three minutes, but also identification of recurrent laryngeal nerves and inferior thyroid arteries.

    BACKGROUND Ligation of the left gastric artery (LLGA), which supplies the fundus of the stomach, may reduce the appetite hormone ghrelin, resulting in weight control. The aim of this study was to compare LLGA and sleeve gastrectomy (SG) in terms of postoperative outcomes in a rat model. MATERIAL AND METHODS Fifteen male Wistar albino rats, weighing >350 grams (range 350-525 grams), were enrolled in LLGA (N=5), SG (N=5), and control (N=5) groups. Blood samples were drawn preoperatively and also during the first and fourth week postoperatively to assay ghrelin and leptin hormone levels. Body weight was measured in each group. RESULTS The maximum reduction in ghrelin level (41.5%) was found in the LLGA group. Considerable% total weight loss (TWL) (mean 24.1%) was observed in the SG group, and slight%TWL was noted in the control and LLGA groups (means of 0.1% and 2.1%, respectively). There was no significant difference in mean percent weight change between the LLGA and the SG groups (p=0.08). Blood sample analysis revealed no statistically significant changes in ghrelin or leptin levels between the groups (p=0.9 and p=0.3, respectively). CONCLUSIONS We present evidence that LLGA causes the same reduction in ghrelin hormone levels as SG at 4 weeks after surgery in a rat model. However, LLGA did not cause the same%TWL as SG. The mechanism of weight loss in SG is most likely due to restriction and to the effects of the procedure, rather than due to neurohormonal changes.

    Metachronous metastatic paraganglioma in jejunum as a rare entity: A case report
    (2015-03-01) Bektasoglu, HÜSEYİN KAZIM; CIPE, Gokhan; YARDIMCI, ERKAN; Arici, DİLEK SEMA; HASBAHCECI, Mustafa; KARATEPE, Oguzhan; MUSLUMANOGLU, Mahmut; BEKTAŞOĞLU, HÜSEYİN KAZIM; YARDIMCI, ERKAN; ARICI, DILEK SEMA
    Pheochromocytomas and paragangliomas are neuroendocrine tumors that arise from chromaffin cells of adrenal medulla and extra-adrenal paraganglia, respectively. The recurrence of these neuroendocrine tumors as a jejunal mass causing obstruction in the small intestine is an exceptional entity. The present study reports the case of a 70-year-old male who presented to the Emergency Department of Bezmialem Vakif University Hospital with abdominal pain and vomiting. The patient possessed a history of left nephrectomy due to malignant pheochromocytoma that had invaded into the left kidney eight months prior to presentation. Bowel obstruction was diagnosed and the patient underwent a laparoscopic procedure. Partial resection of the jejunum was performed and immunohistochemical studies revealed the lesion to be malignant paraganglioma. The majority of paragangliomas are chemo- and radioresistant. Surgical excision remains the primary treatment. Metachronous paraganglioma arising from the small intestine is an extremely rare entity and may be a relevant consideration in patients presenting with bowel obstruction.

    Nonclosure of the Peritoneum during Appendectomy May Cause Less Postoperative Pain: A Randomized, Double-Blind Study
    (2019-01-01) BEKTAŞOĞLU, HÜSEYİN KAZIM; Hasbahceci, Mustafa; YIĞMAN, SAMET; YARDIMCI, ERKAN; KUNDUZ, ENVER; MALYA, FATMA ÜMİT; BEKTAŞOĞLU, HÜSEYİN KAZIM; YIĞMAN, SAMET; YARDIMCI, ERKAN; KUNDUZ, ENVER; MALYA, FATMA ÜMİT
    Objective: We aim to evaluate the effect of peritoneal closure on postoperative pain and life quality associated with open appendectomy operations. Methods: This is a single-center, prospective, randomized, and double-blinded study. Here, 18-65-year-old patients who underwent open appendectomy for acute appendicitis were included. Demographic data of the patients, operation time, length of hospital stay, pain scores using a 10 cm visual analogue scale (VAS) on the first postoperative day, quality of life assessment using the EuroQol-5D-5L questionnaire on postoperative 10th day, deep wound dehiscence, bowel obstruction, and mortality data were recorded. Results: In total, 112 patients were included in the study. The demographic data showed no significant difference between the groups. The median VAS score was lower in the group with open peritoneum, but this difference was not statistically significant (3 vs. 4, p=0.134). The duration of surgery was significantly shorter in the peritoneal nonclosure group (31.0 ± 15.1 vs. 38.5 ± 17.5 minutes, p=0.016). Overall complication rates and life quality test (EuroQol-5D-5L) results were similar between groups. Conclusion: Nonclosure of the peritoneum seems to shorten the duration of surgery without increasing complications during open appendectomy. Postoperative pain and life quality measures were not affected by nonclosure of the peritoneum. This trial is registered with NCT02803463.

    Evaluation of gastro-oesophageal reflux disease after Sleeve Gastrectomy and the results of laparoscopic double loop gastric bypass in revisional surgery
    (2019-12-27T00:00:00Z) Yardımcı, Erkan; Coşkun, Halil; YARDIMCI, ERKAN; COŞKUN, HALIL
    Introduction: Gastroesophageal reflux (GERD) might be occurred after Sleeve Gastrectomy (SG). In this study, we aimed to show the results of preoperative diagnostic tests and laparoscopic double loop gastric bypass (LDLGB) surgery for de novo GERD after SG. Material and Methods: From January 2018 to July 2019, 8 patients who underwent LDLGB for the conversion of SG because of GERD analyzed retrospectively. All patients who suffered from symptomatic and/or resistant reflux after SG underwent esophagogastroduodenoscopy (EGD), 24-hour esophageal pH meter and esophageal manometry. In the LDLGB procedure, sleeved stomach was transected above the incisura angularis via linear stapler to create the gastric pouch. The biliary limb was measured 100 cm distal to the Treitz ligament and gastrojejunostomy was performed using a linear stapler. Starting at this level, the alimentary limb was measured up to 100 cm and fixed by stitching it to the biliary limb. Side-to-side jejunojejunostomy was performed between alimentary and biliary limbs. Finally, the biliary loop and alimentary loop were separated using a linear stapler. Results: The mean preoperative BMI was 32±3.9 kg/m2 . At EGD, class A esophagitis and alkaline reflux(bile) gastritis was found in 75% and 87.5% of cases, respectively. The mean DeMeester score and mean lower esophageal sphincter pressure was 66.3 and 16.4±5.2 mmHg, respectively. The mean operation time was 164±24 minute. There was no complication recorded. The mean BMI was 25.7±1.4 kg/m2 in the follow-up period (mean 12.3±3.2 months). Reflux symptoms completely resolved in all patients. Conclusion: The evaluation of de novo GERD after SG is important and it should be diagnosed by appropriate tests. Conversion of SG to LDLGB is a reliable and feasible technique in the treatment of de novo GERD.
