Yöntem: 2012 ile 2019 yılları arasında Şanlıurfa Eğitim ve Araştırma Hastanesi ve Mehmet Akif İnan Eğitim ve Araştırma Hastanesi'nde yapılan 4642 apendektomi operasyonu retrospektif olarak değerlendirildi. Yaş, cinsiyet, ameliyat öncesi klinik bulgular, histopatolojik sonuçlar, operasyon raporları, izlem süresi ve metastaz durumu elektronik ortamda incelenerek rapor edildi. Bulgular: Şanlıurfa ilimizin iki büyük hastanesinde arasında acil servise başvuran ve apandektomi yapılan 4642 hastanın histopatolojik incelemesinde 25 hastaya karsinoid tümör (nöroendokrin tümör) tanısı konuldu. Hastalarımızdan 13'ü erkek 12 tanesi de bayan idi. Hastalarımızın yaş ortalaması 33,2 idi. Hastalarımızı ortalama takip süremiz 5-62 aydı. Histopatolojik olarak hepsinde iyi diferensiye karsinoid tümör rastlanan hastalarımızın takiplerinde hiçbirinde uzak metastaz tespit edilmemişti. Sonuç: Karsinod tümörler çoğunlukla akut apandisit operasyonu sonrasında insidental olarak saptanan ve apendiksin en sık rastlanan tümörleridir. Bu tümörlerin az rastlanması nedeniyle histopatolojik değerlendirme ve operasyon sonrası takibi önem arz etmektedir. Bizim çalışmamızda oran olarak sık görülmese bile genç popülasyonda sık görülmesi ve ileri evrelerde metastaz ihtimali nedeniyle bu olguların yakın takibi önemlidir.

The patients were operated due to mesenteric cysts in the general surgery clinics of two Training and Research Hospital between 2010 and 2019; age, gender, preoperative clinical findings, computed tomography (CT) findings, localization of the mass, surgical procedure, morbidity, histopathological results, and follow-up period status were analyzed and reported electronically. The patients generally applied with the complaints of abdominal pain, palpable abdominal mass, and abdominal distention. Fourteen (63.7%) of the cases were male and 8 (36.3%) were female. The mesenteric cysts were located in the small intestine in 18 cases and colon in 4 cases. In the histopathological examination of the surgical materials, simple cyst was detected in 17 cases, lymphangioma in 4 cases, colon adenocarcinoma, and simple cyst in 1 case. In the postoperative period, superficial surgical site infection developed in 3 patients and morbidity developed in 1 patient due to anastomotic leakage. Although mesenteric cysts are rarely seen, although most of them are not histopathologically malignant, they can reach large sizes and require extensive surgical operation, and related morbidities can be seen. Therefore, mesenteric cysts should be followed carefully in the postoperative period as well as during the diagnosis and surgical treatment process.

In our study, we aimed to reveal the surgical approach of our clinic, features of tumors, and clinical presentations in line with literature in cases of appendix mucocele. Methods Fourteen appendix mucocele patients who were admitted in our hospital between 2012 and 2019 were examined retrospectively in the electronic recording medium. Our patients were evaluated in terms of age, gender, clinical status, operation, imaging results, and pathology results. Results Of the fourteen patients, 12 applied to the emergency department and 2 to the general surgery clinic. All of our patients had abdominal pain at the time of admission. In the physical examination, 5 (35%) patients had defenses, 10 (71%) patients had rebound tenderness, and 12 (85%) patients had tenderness. In preoperative imaging studies, 11 patients were interpreted as having acute appendicitis and 3 patients were evaluated as having appendix mucocele. The pathological results were reported as 6 patients had appendiceal mucocele and 8 patients had appendiceal mucocele together with acute appendicitis. Conclusion Appendiceal mucocele is a disease which generally causes similar clinical findings of acute appendicitis. Ultrasound and CT may be useful in preoperative diagnosis. Surgical treatment options of mucocele are open or laparoscopic appendectomy, cecum resection, and right hemicolectomy. Although its incidence is low, due to pseudomyxoma peritonei, it is a pathology that requires careful surgery.

Materials and Methods: Patients who were admitted to the general surgery clinic of Ceylanpinar State Hospital between March 2018 and March 2019 with the suspicion of ingestion of foreign bodies in the upper gastrointestinal tract and food residue were evaluated retrospectively. Findings: The mean age of our patients was 31.3 (min-max: 18-76). Endoscopy without sedation was performed to 3 patients (37.5%) due to the feeling of stuck. In 2 patients, the bone fragments detected in the esophagus were excised with the help of endoscopic forceps. One of the three endoscopic procedures have failed. Patient whose endoscopy was unsuccessful and five other patients were followed-up medically in order to let foreign bodies or food residues to leave the digestive tract spontaneously. None of the patients had esophageal disease or a known psychiatric disorder. The mean duration of admission to the hospital was 12.5 (min-max: 6-36) hours. Three patients (37.5%) had foreign body feeling and dysphagia. Four of the patients (50%) had foreign bodies and the rest of the patients had food residue. The localization of foreign bodies or food residues were detected as; stomach in 1 patient (12.5%), esophagus in 3 patients (37.5%) and intestines in other 4 patients (50%). None of the patients required surgical intervention. Conclusion: In the early period, endoscopic procedures show a high success rate without complications in the treatment of foreign bodies in the upper gastrointestinal tract. However, it is an appropriate approach to wait for the spontaneous exit of the foreign body in cases that the foreign body have already passed the upper gastrointestinal system.

The model solution was prepared with BR29 using distilled water. The effects of initial dye concentration, Na 2 SO 4 concentration as supporting electrolyte, current density, flow rate and initial pH on the removal efficiency were investigated, and practically, complete BR29 removal (over 99%) was obtained in all the studies. After optimum experimental conditions were determined, textile wastewater has also studied by monitoring the destruction of color and COD. With the textile wastewater, 97.2% of color and 91% of COD removal were, respectively, achieved at the current density of 1 mA/cm 2. Microtox toxicity tests were performed in both BR29 solution and textile wastewater under optimum experimental conditions, and relatively good toxicity reductions were obtained with respect to the initial values. According to the results, BDD anode was seen to be a unique material for the degradation of BR29 and COD and also the reduction of toxicity simultaneously.
