    (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.

    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.

    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.

    Mechanism of body weight reducing effect of oral boric Acid intake.
    (2013-01-01) Aysan, E; SAHIN, F; TELCI, D; ERDEM, M; MUSLUMANOGLU, M; YARDıMCı, ERKAN; BEKTASOGLU, HÜSEYİN KAZIM; AYŞAN, MUSTAFA ERHAN; YARDIMCI, ERKAN; BEKTAŞOĞLU, HÜSEYİN KAZIM
    Objective. The effect of oral boric acid intake on reducing body weight has been previously demonstrated although the mechanism has been unclear. This research study reveals the mechanism. Subjects. Twelve mice were used, in groups of six each in the control and study groups. For five days, control group mice drank standard tap water while during the same time period the study group mice drank tap water which contains 0.28 mg/250 mL boric acid. After a 5-day period, gene expression levels for uncoupling proteins (UCPs) in the white adipose tissue (WAT), brown adipose tissue (BAT), and skeletal muscle tissue (SMT) and total body weight changes were analyzed. Results. Real time PCR analysis revealed no significant change in UCP3 expressions, but UCP2 in WAT (𝑃: 0.0317), BAT (𝑃: 0.014), and SMT (𝑃: 0.0159) and UCP1 in BAT (𝑃: 0.026) were overexpressed in the boric acid group. In addition, mice in the boric acid group lost body weight (mean 28.1%) while mice in the control group experienced no weight loss but a slight weight gain (mean 0.09%, 𝑃 < 0.001). Conclusion. Oral boric acid intake causes overexpression of thermogenic proteins in the adipose and skeletal muscle tissues. Increasing thermogenesis through UCP protein pathway results in the accelerated lipolysis and body weight loss.
