Publication Metadata only Rare Entities of Histopathological Findings in 755 Sleeve Gastrectomy Cases: a Synopsis of Preoperative Endoscopy Findings and Histological Evaluation of the Specimen(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, HÜSEYİNLaparoscopic 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.Publication Metadata only Results of 150 Subtotal Parathyroidectomies for Secondary Hyperparathyroidism(2020-03-01T00:00:00Z) Aysan, Erhan; PIRALIYEV, ELNUR; YIĞMAN, SAMET; PIRALIYEV, ELNUR; YIĞMAN, SAMETWe evaluated our experience of subtotal parathyroidectomy (SP) for secondary hyperparathyroidism (SHP) cases. We evaluated retrospectively our 150 SP operations due to SHP. Serious hypocalcemia (< 6.5 mg/dL) developed in 23 (15.3%) patients, and we performed cryopreserved parathyroid cell autotransplantation in four cases with successful results. Recurrent hyperparathyroidism developed in 3 (2%) cases, and persistent hyperparathyroidism was observed in 22 (14.6%) cases. Upon reoperation in nine persistent hyperparathyroidism cases, we found supernumerary parathyroid glands in three cases, remnant tissue hyperplasia in four cases, and ectopic parathyroid glands in two cases. Among cases in which four glands cannot be found during surgery, the permanent HP rate is high. Serious hypocalcemia may develop postoperatively, and cryopreserved parathyroid autotransplantation may be inevitable in some of these cases.Publication Metadata only The Effects of the Staple Line Reinforcement Procedures on Gastrointestinal Symptoms and Its Early Results in Sleeve Gastrectomy(2022-08-01T00:00:00Z) YAPALAK, YUNUS; YIĞMAN, SAMET; GÖNÜLTAŞ, CEREN; COŞKUN, Halil; YARDIMCI, ERKAN; YAPALAK, YUNUS; YIĞMAN, SAMET; GÖNÜLTAŞ, CEREN; COŞKUN, HALIL; YARDIMCI, ERKANBackground: The laparoscopic sleeve gastrectomy (LSG) procedure is the most common bariatric surgical technique worldwide, but controversy continues over staple line reinforcement (SLR) techniques. This prospective randomized study aimed to compare the effects of SLR methods on early postoperative complications and gastrointestinal symptoms in patients undergoing LSG for morbid obesity.Publication Metadata only Role of obesity and abdominal shape morphometric features to predict postoperative complications and quality of lymph node dissection of gastrectomy for gastric cancer(2017-01-01) HASBAHCECI, MUSTAFA; Mehdi, Elnur; Malya, FATMA ÜMİT; Kunduz, ENVER; Memmi, NAİM; Yigman, SAMET; Akcakaya, ADEM; MALYA, FATMA ÜMİT; KUNDUZ, ENVER; MEMMİ, NAİM; YIĞMAN, SAMET; AKÇAKAYA, ADEMObesity and abdominal shape morphometric features have been thought to be independent risk factors for surgical outcomes after gastrectomy.
