Item Unusual Findings in Appendectomy Specimens of Adults: Retrospective Analyses of 1466 Patients and a Review of Literature(2014) Yabanoglu, Hakan; Caliskan, Kenan; Aytac, Huseyin Ozgur; Turk, Emin; Karagulle, Erdal; Kayaselcuk, Fazilet; Tarim, Mehmet AkinBackground: Diseases and tumors of the appendix vermiformis are very rare, except acute appendicitis. Objectives: This retrospective study was conducted to document the unusual findings in appendectomy specimens. Patients and Methods: Data of 1466 adult patients were gathered retrospectively. Appendectomy was performed in 1169 and in 297 patients following a diagnosis of acute appendicitis and during other abdominal operations, respectively. The data of 57 (3.88 %) patients who were pathologically reported to have unusual appendix findings were retrospectively collected. The records were analyzed according to patients' age, gender, clinical presentations, operative reports, pathological reports and follow up. Results: Unusual pathologic examination findings were detected in the appendectomy specimens of 57 patients with a mean age of 48.34 +/- 19. Twenty-nine patients (50.8%) were male and 28 (49.2%) were female. Normal appendix tissues were observed in specimens of 26 (45.6%) patients and inflamed appendix in 31 (54.3%). The most common unusual finding was parasitic diseases of the intestine. Pathological diagnosis of malignancy and benign features were reported in specimens of 14 and 43 patients, respectively. Macroscopic evaluation of appendectomy specimens during surgery might result in negligence of the presence of unusual pathology. Conclusions: Even if the macroscopic appearance of the specimen is normal or acute appendicitis, we suggest routine histopathological examination.Item Vascular Variations and Anastomosis Techniques in Renal Transplant Donors(2015) Haberal, Mehmet; Arer, Ilker Murat; Yabanoglu, Hakan; Caliskan, Kenan; Parlakgumus, Alper; Yildirim, Sedat; Moray, GokhanPurpose: We aimed to share our experience about vascular variations and anastomosis tecniques in renal transplant donors. Material and Methods: 128 donor nephrectomy performed in our hospital between February 2010 and June 2014 were included in our study. Donors were retrospectively analyzed according to age, sex, comorbidity, operation history, site of nephrectomy, vascular variation and anastomosis techniques. Results: 21 (% 16,4) patients have left-sided, 19 (% 14,8) have right-sided and 13 (% 10,2) have bilateral vascular variation. 29 (% 21,2) unilateral double renal artery, 8 (% 6,3) unilateral double renal artery and vein, 4 (% 3,2) unilateral triple renal artery, 3 (% 2,4) early branching renal artery, 2 (% 1,6) unilateral double renal vein and 2 (% 1,6) polar artery are vascular variations observed. of 92 (% 71,9) recepients anastomosis type was end to side between renal artery and external iliac artery and end to side between renal vein and external iliac vein, 32 (% 25) end to end between renal artery and external iliac artery and end to side between renal vein and external iliac vein, 4 (% 3,1) end to side between renal artery and external iliac artery and end to side between renal vein and external iliac vein and end to side between 2nd renal artery and external iliac artery. Conclusion: Preoperative evaluation of renal vasculature of transplant donors is an important issue in means of decreasing peroperative vascular complications and decision for nephrectomy site.Item Mucormycosis with Orbital Apex Syndrome in a Renal Transplant Recipient(2015) Haberal, Mehmet; Kursun, Ebru; Turunc, Tuba; Demiroglu, Yusuf Ziya; Yabanoglu, Hakan; Demir, Senay; Caliskan, Kenan; Moray, Gokhan; Arslan, HandeMucormycosis is a rarely encountered invasive fungal infection with high mortality. Solid organ transplantation is one of the risk factors for mucormycosis. Mucormycosis can be classified in six different groups according to the anatomical localization; rhinocerebral, pulmonary, cutaneous, gastrointestinal, disseminated, and other less common involvements. This paper presented a mucormycosis case with rhinoorbitocerebral involvementin a renal transplantation receiver, which manifested with orbital apex syndrome.Item Laparoscopic Repair of Morgagni Hernia(2015) Arer, Ilker Murat; Yabanoglu, Hakan; Aytac, Huseyin Ozgur; Caliskan, Kenan; Torer, NurkanMorgagni hernia is a congenital herniation of abdominal contents into the thoracic cavity through a retrosternal diaphragmatic defect and make up about 1 % - 5 % of all types of congenital diaphragmatic hernias. Surgical repair of Morgagni hernias is usually indicated when patients are symptomatic and have a high risk of strangulation or incarceration of the contained viscera. 71-year-old male patient admitted to emergency department with a 2-day history of abdominal pain, vomiting and obstipation. Laparoscopic repair for Morgagni hernia was performed. Laparoscopic repair for Morgagni hernia with mesh repair is secure, satisfactory and easily performed.Item The Effect of the Use of Synthetic Mesh Soaked in Antibiotic Solution on the Rate of Graft Infection in Ventral Hernias: A Prospective Randomized Study(2015) Yabanoglu, Hakan; Arer, Ilker Murat; Caliskan, Kenan; 25590831Wound infections and seroma formations are important problems in ventral hernia repair operations using synthetic mesh grafts. The aim of this study was to investigate the effect of the use of synthetic mesh soaked in vancomycin solution on the rate of graft infection. The total number of subjects was 52. The subjects were randomized into 2 groups using a software program. Group 1 (n = 26) was the control group. In group 2 (n = 26), synthetic mesh was soaked in a Vancomycin solution before it was implanted. The patients were compared with respect to demographic characteristics and preoperative, intraoperative, and postoperative variables. There were no significant differences between the groups with respect to the available variables. Seroma development was significantly more common in group 2 (P < 0.041). Three patients (5.7%) developed superficial wound infection, and 9 (17%) developed surgical site infection 2-type wound-site infection. No significant difference was found between the groups in terms of infection. The use of synthetic mesh soaked in vancomycin solution had no beneficial effects on the rate of wound-site infection. Future randomized, controlled, large-scale studies using the same mesh and suture types, and meshes soaked in larger spectrum antibiotics are needed.Item A Rare Cause of Acute Pancreatitis: Unexpected Travel of the Biliary Catheter(2016) Aytac, Huseyin Ozgur; Caliskan, Kenan; 26966629Item Can red cell distribution width be used as a predictor of acute cholecystitis?(2017) Arer, Ilker Murat; Yabanoglu, Hakan; Caliskan, Kenan; 0000-0003-0268-8999; 0000-0002-1161-3369; 0000-0002-8767-5021; 28740954; AAJ-7865-2021; AAJ-7201-2021; AAK-2011-2021Objective: Acute cholecystitis is a common disease requiring accurate markers for diagnosis and proper treatment. The aim of this study was to investigate the role of red cell distribution width (RDW) in acute cholecystitis. Material and Methods: 299 were included in the study. The subjects were divided into 2 groups; group 1 (n: 46) acute cholecystitis group and group 2 (n:253) chronic cholecystitis group. The patients were compared with respect to demographic characteristics, white blood cell count, C-reactive protein, and red cell distribution width. Results: A statistically significant difference was observed between groups with respect to gender, white blood cell count, C-reactive protein, and red cell distribution width level (p<0.05). The mean red cell distribution width level of group 1 and 2 was 14.19 +/- 2.02% and 15.03 +/- 2.51%, respectively. Conclusion: Red cell distribution width level can be used as a predictor of acute cholecystitis. Multicenter prospective studies should be performed to elucidate the exact role of RDW level in acute cholecystitis.Item Long-term results of retromuscular hernia repair: a single center experience(2017) Arer, Ilker Murat; Yabanoglu, Hakan; Aytac, Huseyin Ozgur; Ezer, Ali; Caliskan, Kenan; 0000-0002-3583-9282; 0000-0002-1161-3369; 0000-0002-3834-9924; 0000-0002-8767-5021; 0000-0003-0268-8999; 28904662; AAJ-7865-2021; AAJ-7913-2021; AAJ-8558-2021; AAJ-7201-2021; AAK-2011-2021Introduction: Incisional hernia (IH) is one of the most frequent postoperative complications after abdominal surgery. There are multiple surgical techniques described for IH repair. The aim of the study is to evaluate the effect of primary fascial closure on long-term results in retromuscular hernia repair (RHR) for incisional hernias. Methods: A total of 132 patients underwent RHR for IH were included in our study. 109 patients were evaluated in 2009 and 55 patients in 2015 for short and long-term results. Results: Among 132 patients perfromed RHR, fascia was closed in 107 (81%) and left open in 25 (19%) patients. The mean age of patients was 57.9 +/- 11.8 years. Average mesh area was 439.8 +/- 194.6 cm(2), hernia area was 112 +/- 77.5 cm(2) and open area after repair was 40.8 +/- 43.3 cm(2). Mean follow-up of 104 patients regarding postoperative complications evaluated in 2009 was 30.7 +/- 14.1 months. Recurrent IH was observed in 6 (4.5%) patients according to data collected in 2009. Long-term results were; mean follow-up period was 91 +/- 20.2 months (20-112 months) and recurrent IH was observed in 4 (7.3%) patients. Conclusion: Retromuscular repair for incisional hernia regardless of the fascial closure gives high patient satisfaction, less recurrence rates and complications in long-term follow-up.
