Item A Rare Cause of Small Intestinal Obstruction: Obturator Hernia(2014) Karagulle, Erdal; Turk, Emin; Yabanoglu, Hakan; 0000-0002-1161-3369; 0000-0003-4766-3373; AAJ-7865-2021; AAJ-5609-2021Obturator hernia is an uncommon disease and its diagnosis is challenging. It is more prevalent in thin, multiparous, elderly women. In this case report a 93-year-old woman patient with a right-sided strangulated obturator hernia was discussed with review of the relevant literature.Item A Comparative Study of Conservative versus Surgical Treatment Protocols for 77 Patients with Idiopathic Granulomatous Mastitis(2015) Yabanoglu, Hakan; Colakoglu, Tamer; Belli, Sedat; Aytac, Huseyin Ozgur; Bolat, Filiz Aka; Pourbagher, Aysin; Tezcaner, Tugan; Yildirim, Sedat; Haberal, Mehmet; 0000-0003-2031-7374; 0000-0002-3462-7632; 0000-0002-5735-4315; 0000-0002-3641-8674; 0000-0002-3583-9282; 0000-0002-1161-3369; 25858348; HJZ-1654-2023; AAJ-8097-2021; AAF-4610-2019; AAD-9865-2021; AAJ-7913-2021; AAJ-7865-2021The purpose of this study was to analyze the clinical features and demographic data of patients with idiopathic granulomatous mastitis (IGM) and to compare the results of conservative versus surgical treatment protocols. The demographic data, clinical findings, microbiological and pathologic features, scanning and treatment methods, recurrence, and recovery rates of 77 patients were analyzed retrospectively. The patients were divided into two groups based on the type of treatment received. Core biopsies were used to diagnose 37 patients: 26 using incisional biopsies and 14 using excisional biopsies. Of the patient population with IGM, 31 were treated with surgical excision, one with a simple mastectomy, and one with a subcutaneous mastectomy combined with a breast implant, whereas 44 were treated with steroids. The recovery rates of the 44 patients who were treated conservatively were 6 (1-15) months while for the 33 patients who were treated surgically, it was 1 (1-5) month (p=0.001). Nine patients from the conservative treatment group experienced a recurrence while there were no recurrences in the surgically treated group (p=0.009). Among all patients, the recurrence rate was 11.7% (9/77) while the average follow-up period was 16.57 +/- 18.57months. As a comparative study between conservative treatment protocols and surgical ones for patients with idiopathic granulomatous mastitis (IGM), this study is the largest to date. A wide surgical excision is the preferred approach for treating patients with IGM because of the low recurrence rate.Item Reverse Cover-Up: Easy Way to Remove the Appendix(2015) Aytac, Huseyin Ozgur; Torer, Nurkan; Yabanoglu, Hakan; Nursal, Tarik Zafer; 0000-0003-0268-8999; 0000-0002-1161-3369; 0000-0002-3583-9282; AAK-2011-2021; IQV-1169-2023; AAJ-7865-2021; AAJ-7913-2021Item Predictors Determining the Status of Axilla in Breast Cancer: Where is PET/CT on That?(2015) Aytac, Huseyin Ozgur; Colacoglu, Tamer; Nursal, Gul Nihal; Nursal, Tarik Zafer; Bolat, Filiz Aka; Yabanoglu, Hakan; Yildirim, Sedat; Moray, Gokhan; 0000-0002-3583-9282; 0000-0003-0268-8999; 0000-0003-2498-7287; 0000-0002-5735-4315; 0000-0002-5302-4386; 0000-0002-3462-7632; 0000-0002-1161-3369; 0000-0003-2031-7374; 26537078; AAJ-7913-2021; AAK-2011-2021; AAE-1041-2021; AAF-4610-2019; R-3735-2016; IQV-1169-2023; AAJ-8097-2021; AAJ-7865-2021; HJZ-1654-2023Purpose: 18 F-FDG PET/CT has an acceptable specificity but a low sensitivity on the prediction of axillary lymph node (ALN) metastasis in breast cancer. We analyzed the factors that could possibly affect this prediction. Methods: The records of 270 patients with T1-2 invasive breast cancer who underwent surgery, 116 of whom had been evaluated by preoperative 18 F-FDG PET/CT were reviewed. Prediction of ALN status by PET/CT according to tumor stage, estrogen receptor (ER), progesterone receptor (PgR) and HER2 status, histology, age and sentinel node properties was assessed. Results: ALN metastasis was present in 62 of 131 T1 (43.7%) and 106 of 142 T2 tumors (74.6%), 20 of 46 (43.5%) ER(-) and 146 of 222 (65.8%) ER(+) tumors, 38 of 71 (53.5%) PgR(-) and 127 of 200 (63.5%) PgR(+) tumors. On multivariate analysis only the tumor size (>2 cm) independently correlated with ALN metastasis (Odds ratio/OR=3.1). None of the other parameters had statistical significance in terms of ALN prediction on FDG-PET/CT. Conclusion: Though T2 tumors showed increased tendency to metastasize to the axilla, prediction of ALN metastasis in preoperative FDG-PET/CT was not associated with any of the predictive factors.Item Tension-Free Primary Closure for the Treatment of Pilonidal Disease(2015) Arer, Ilker Murat; Yabanoglu, Hakan; Caliskan, Kenan; 0000-0002-1161-3369; 0000-0003-0268-8999; 0000-0002-8767-5021; 26567718; AAJ-7865-2021; AAK-2011-2021; AAJ-7201-2021AIM: Pilonidal disease (PD) is a common disorder that usually affects young population and generally seen in intergluteal region. Conservative and surgical treatment options have been utilized. Many surgical techniques including primary closure, marsupialization and flap procedures have been described. The present study aims to evaluate the optimal surgical method for the treatment of PD. MATERIAL AND METHODS: A total of 151 patients underwent pilonidal disease surgery between January 2007 and September 2014 were enrolled in this study. Patients were compared according to age, sex, operation time, length of RESULTS: A total of 151 patients with a mean age of 25.18 years (range 14-66) presented with pilonidal disease were evaluated. Primary closure (PC) and tension-free primary closure (TFPC) were performed in 105 (69.5%) and 46 (30.5%) patients, respectively. There was no statistical difference between groups according to age, sex, operation time and length of hospital stay. Only 9 patients (8.6%) in PC and 3 patients (65%) in TFPC have postoperative recurrent disease. of 17 patients (7.9%) dehiscence was seen, 15 (14.3%) were in PC group and 2 (4.3%) were in TFPC group. Postoperative seroma or wound infection was seen in 16 patients (10.6%). CONCLUSION: Tension-free primary closure is a method that is effective as primary closure.Item Early Infections in Renal Transplant Recipients: Incidence, Risk Factors, and Causative Microorganisms(2015) Yabanoglu, Hakan; Aliskan, Hikmet Eda; Caliskan, Kenan; Arer, Ilker; Akdur, Aydincan; Yildirim, Sedat; Moray, Gokhan; Haberal, Mehmet; 0000-0002-1161-3369; 0000-0002-8726-3369; 0000-0002-5735-4315; 0000-0001-9060-3195; 0000-0002-8767-5021; 0000-0002-3462-7632; 0000-0003-0268-8999; 0000-0003-2498-7287; 26640902; AAJ-7865-2021; AAA-3068-2021; AAF-4610-2019; AAE-2282-2021; AAJ-7201-2021; AAJ-8097-2021; AAK-2011-2021; AAE-1041-2021Objectives: This study aimed to compare renal transplant recipients with and without infection with respect to demographic and clinical characteristics as well as risk factors; to determine the incidence of posttransplant infections; and to study the antibiotic resistance patterns of bacterial species identified as the causative organisms in posttransplant infections. Materials and Methods: This study included a total of 136 patients undergoing renal transplant in a 4-year period. The patients were categorized into 2 groups. The 2 groups were compared with each other with respect to general clinical and demographic variables and the number and frequency of infectious attacks within a 1-year follow-up, infection type, and antibiotic resistance patterns. Results: Ninety-two (67.6%) of the subjects were male and 44 (32.4%) were female. A total of 57 (41.9%) patients developed 128 infectious attacks. Urinary tract infections were the most common infections (42.1%). There was a significant correlation between a clinically relevant urinary culture proliferation and postoperative infection rate (P =.002). There was a significant correlation between antimicrobial resistance and the number of infectious attacks (P =.023). There was a significant correlation between the proliferation of Extended Spectrum Beta Lactamase-positive Enterobactericeae species and the number of infectious attacks (P =.000). Conclusions: Presence of a clinically relevant proliferation in the preoperative urinary culture, which was identified as a risk factor for infection, increased the number of infectious attacks. Moreover, Extended Spectrum Beta Lactamase-positive Enterobactericeae species increased the number of infections. These 2 principle results should be taken into account in patient management.Item Management of Symptomatic Arterial and Venous Aneurysms in Hemodialysis Patients Related To Arteriovenous Fistulas(2018) Avci, Tevfik; Yabanoglu, Hakan; Moray, Gokhan; Haberal, Mehmet; https://orcid.org/0000-0001-5225-959X; https://orcid.org/0000-0002-1161-3369; https://orcid.org/0000-0003-2498-7287; https://orcid.org/0000-0002-3462-7632; AAF-1698-2021; AAJ-7865-2021; AAE-1041-2021; AAJ-8097-2021AIM: Our aim in this study is to present the management of the symptomatic aneurysms that are related to AVF. MATERIAL AND METHODS: Between January 2011 and January 2017, 50 patients who were operated due to symptomatic AVF aneurysms were evaluated. Forty-four (88%) patients' fistulas were closed for symptomatic venous aneurysm. In 6 (12%) patients true brachial artery aneurysm were present and a segmental artery resection with its repair was performed. RESULTS: The most common symptomatic aneurysm was seen on the brachiocephalic fistula (n=32, 64%). The symptoms of the patients were; aneurysm thrombosis (n=15, 30%), steal syndrome (n=9, 18%), rupture/massive bleeding (n=7, 14%), infection (n=7, 14%), skin necrosis (n=5, 10%), venous hypertension (n=4, 8%) and high output cardiac failure (n=1, 2%). Nine (18%) patients had two or more symptoms. While the mean duration of dialysis of patients who underwent venous aneurysmectomy was 69 +/- 4.2 years, patients who underwent arterial aneurysmectomy and brachial artery repair was 11.7 +/- 3.6 years (p = 0.012). DISCUSSION: Arterial aneurysm is a rare complication of vascular access. Although it causes serious symptoms including those of related such as thrombosis, ischemia, nerve compression, the most important complication is aneurysm rupture. Therefore, preoperative evaluation and appropriate surgical interventions will prevent morbidities that may arise. CONCLUSION: The choice of a treatment modality in patients with a symptomatic arteriovenous fistula aneurysms is to maintain the continuity of the arteriovenous fistula but when acute bleeding occurs in an unstable patient, ligation of fistula should be considered.Item Comparison of the Early Term Complications and Patency Rates of the Standard (Parachute) and Diamond-Shaped End-To-Side Anastomosis Techniques in Arteriovenous Fistulas Created for Hemodialysis(2018) Yabanoglu, Hakan; Kus, Murat; Arer, Ilker Murat; Bali, Cagla; Avci, Tevfik; Akdur, Aydincan; Caliskan, Kenan; https://orcid.org/0000-0002-1161-3369; https://orcid.org/0000-0001-6529-7579; https://orcid.org/0000-0003-2615-1918; https://orcid.org/0000-0001-5225-959X; https://orcid.org/0000-0002-8726-3369; https://orcid.org/0000-0002-8767-5021; 30060787; AAJ-7865-2021; AAJ-7870-2021; AAI-8790-2021; AAF-1698-2021; AAA-3068-2021; AAJ-7201-2021Objective: To compare the early-term patency and complication rates of the end-to-side anastomosis techniques parachute and diamond-shaped techniques in arteriovenous fistulas. Study Design: Prospective randomised study. Place and Duration of Study: Department of General Surgery, Adana Baskent University Application and Research Hospital, Adana, Turkey, between October 2014 and January 2015. Methodology: Patients with end stage renal disease who underwent arteriovenous fistula creation for hemodialysis were grouped into two according to the anastomosis technique performed. Group 1 was composed of the patients undergoing the standard parachute technique and Group 2 consisted of the patients operated with the diamond-shaped anastomosis technique. The two groups were compared with each other with respect to clinical and demographic data, operative and postoperative variables, and complication and patency rates. Results: A total of 56 patients underwent arteriovenous fistula creation. The overall complication rate was 12.5%. The early-term patency rate was higher in the diamond-shaped anastomosis technique than the standard parachute end-to-side anastomosis technique. Effective dialysis was established after 4 weeks in 48 (85.7%) patients in the overall study group, 23 (82.1%) in Group 1, and 25 (89.2%) in Group 2. However, there was no significant difference between both the techniques with respect to effectiveness of dialysis. Conclusion: Both end-to-side anastomosis techniques have their own advantages and disadvantages. Using a patient-specific suitable technique rather than a standard technique would be more appropriate in arteriovenous fistulas formation.Item Assessment of Atrial Fibrillation and Ventricular Arrhythmia Risk after Transplantation in Patients with End Stage Renal Disease by P Wave/QT Interval Dispersion, Tp-e Interval, Tp-e/QT Interval Ratio(2018) Yilmaz, Mustafa; Altin, Cihan; Tekin, Abdullah; Arer, Ilker; Yabanoglu, Hakan; Caliskan, Kenan; Moray, Gokhan; Ozin, Bulent; Muderrisoglu, Haldun; Haberal, Mehmet; https://orcid.org/0000-0002-2557-9579; https://orcid.org/0000-0002-5658-870X; https://orcid.org/0000-0002-1161-3369; https://orcid.org/0000-0002-8767-5021; https://orcid.org/0000-0003-2498-7287; https://orcid.org/0000-0003-3821-412X; https://orcid.org/0000-0002-9635-6313; https://orcid.org/0000-0002-3462-7632; S-6973-2016; ABD-7304-2021; AAJ-7865-2021; AAJ-7201-2021; AAE-1041-2021; AAD-9938-2021; AAG-8233-2020; AAJ-8097-2021Item The Effect of Subcutaneous Suction Drains on Surgical Site Infection in Open Abdominal Surgery. A Prospective Randomized Study(2016) Arer, Ilker Murat; Yabanoglu, Hakan; Aytac, Huseyin Ozgur; Ezer, Ali; https://orcid.org/0000-0002-1161-3369; https://orcid.org/0000-0002-3583-9282; https://orcid.org/0000-0002-3834-9924; 27025777; AAJ-7865-2021; AAJ-7913-2021; AAJ-8558-2021AIM: Surgical site infection (SSI) is a major problem associated with open abdominal surgery and related to increased morbidity and mortality rates, healthcare costs and also incisional hernia. A negative pressure subcutaneous drain reduces dead space in subcutaneous tissue by preventing accumulation of fluid. The aim of current study was to establish the efficacy of a subcutaneous drainage system for preventing SSI after open abdominal clean-contaminated surgery. MATERIAL AND METHODS: A total of 62 patients underwent abdominal surgery, between November 2014 and March 2015, were enrolled. 48 eligible patients, were randomized into subcutaneous drainage (DG) and no drainage group (NDG). Antibiotic prophylaxis was appiled to each patient. The diagnosis of superficial SSI was made according to the Centers for Disease Control and Prevention's (CDC) definition. RESULTS: The mean age of patients was 48.77 +/- 12.62 years with a male-female ratio of 21:27. No statistical difference between groups was observed for age, sex, comorbidity, incision type, hemoglobin level, blood loss, hospital stay and operation time (P>0.05). 2 (8.7%) patients in DG and 8 (32%) patients in NDG had incisional SSI but no statistical difference was observed (P>0.05). CONCLUSION: SSI appear to be reduced with subcutaneous suction drains in open abdominal surgery however prospective randomized larger scaled studies should be performed on this topic.
