(2015) Yabanoglu, H.; Colakogiu, T.; Aytac, H. O.; Parlakgumus, A.; Bolat, F. A.; Pourbagher, A.; Yildirim, S.; 0000-0002-3583-9282; 0000-0003-0268-8999; 0000-0003-2031-7374; 0000-0002-5735-4315; 0000-0002-1161-3369; 26021788; AAJ-7913-2021; AAK-2011-2021; HJZ-1654-2023; AAF-4610-2019; AAJ-7865-2021
Background : To compare predicting factors for the diagnosis and clinical course of benign and malign/borderline phyllodes tumours (PT) of the breast, and to discuss treatment modalities. Methods : Clinical and demographic characteristics of the patients with histopathological diagnosis of phyllodes tumour were examined. Patients were divided into group 1 (benign PT) and group 2 (borderline/malignant PT). Groups were compared in terms of demographic and clinical characteristics. Results. Of the patients studied, 37(68.5%) had benign, 7 (12.9%) had borderline and 10 (18.5) had malignant histopathology.. A statistically significant relationship was detected between the incidence of malignancy and mass diameter (p = 0.001) and age (p = 0.030) when the two groups were compared. Wide surgical excision was performed on 46 (82.5%) patients, simple mastectomy on 7 (13%) patients and modified radical mastectomy on one (1.9%) patient. Ten (18.5%) patients were re-operated for surgical margin positivity. Local recurrence was determined only in one (1.9%) patient. Distant metastasis due to malignant PT developed in two (3.7%) patients. Conclusion : Among the patients who were considered to have PT, malignancy was likely to be present, especially if the patient's age was over 40 and the diameter of the mass was above 33.5 mm. Therefore, in patients with similar characteristics, surgical margins should be kept slightly wider or wider excisions should be preferred with or without simultaneous reconstructive surgery in appropriate cases.

(2014) Yabanoglu, H.; Aydogan, C.; Karakayali, F.; Moray, G.; Haberal, M.; https://orcid.org/0000-0002-1161-3369; https://orcid.org/0000-0003-1547-1297; https://orcid.org/0000-0002-1874-947X; https://orcid.org/0000-0003-2498-7287; https://orcid.org/0000-0002-3462-7632; 24817291; AAJ-7865-2021; AAJ-5296-2021; AAB-3888-2021; AAE-1041-2021; AAJ-8097-2021
BACKGROUND: The aim of this study was to review our case load of the treatment and outcomes of patients with xanthogranulomatous cholecystitis (XGC). PATIENTS AND METHODS: Data about 21 patients were reviewed retrospectively to determine age, clinical symptoms and findings, preoperative screening, operative findings, surgical history, length of hospital stay, and postoperative complications. RESULTS: There were 14 men and 7 women (mean age, 65 +/- 11.3 yr). Preoperative ultrasonography of 17 patients showed a gallbladder stone in 14 patients, adenomyomatosis plus stones in 2 patients, and a polyp in 1 patient. There were 5 patients with acute cholecystitis and 16 patients with chronic cholecystitis. Gallbladder wall thickening was noted in 3 of the 12 patients who had abdominal computed tomography. Frozen section examinations were done in 5 patients. Radical cholecystectomy was done in 1 patient because of suspected carcinoma. CONCLUSIONS: It is difficult to diagnose XGC preoperatively or intraoperatively, and the definitive diagnosis depends exclusively on pathologic examination.

Ayvazoglu; Yildirim, S.; Moray, G.; Haberal, M.; Yabanoglu, H.; 0000-0002-3641-8674; 0000-0002-0993-9917; 0000-0002-5735-4315; 0000-0003-2498-7287; 0000-0002-1161-3369; 0000-0002-3462-7632; AAD-9865-2021; AAC-5566-2019; AAF-4610-2019; AAE-1041-2021; AAJ-7865-2021; AAJ-8097-2021; AAH-9198-2019
PREOPERATIVE THERAPEUTIC PLASMA EXCHANGE AND SURGICAL TREATMENT IN THYROTOXICOSIS PATIENTS: A SINGLE-CENTRE RETROSPECTIVE COHORT STUDY
(2021) Yabanoglu, H.; Sari, R.; Haydardedeoglu, F. Eksi; Kus, M.; Hargura, A.S.; Arer, I.M.; 0000-0003-3492-9953; 35342473
Context. Therapeutic plasma exchange (TPE) provides time for thyroidectomy in thyrotoxic patients. Objective. TPE is indicated in cases where antithyroid medications cannot be used due to the side effects or attain no adequate hormonal suppression response at the highest dosage and in cases of rapid onset of clinical symptoms. This study presents the treatment results of patients who underwent TPE and were subsequently operated for thyrotoxicosis. Design. The patients who underwent thyroidectomy and TPE between January 1999 and February 2019 were retrospectively analyzed. Subjects and Methods. The files of 27 patients with thyrotoxicosis who performed TPE prior to surgery were analyzed in relation to the demographic and clinical features. Results. We included 15 (55.6%) females, 12 (44.4%) males with a mean age of 44 (23-82) years. The pre-TPE mean free thyroxine (fT4) level was 12 (5-46) pmol/L while free tri-iodothyronine (fT3) level was 34 (17-141) pmol/L. The post-TPE fT4 level was 6 (3-10) pmol/L while the fT3 level was 21 (12-41). There was one case of an allergic reaction during the procedure. In the postoperative follow-up, there was transient hypocalcemia in 8 (29%) patients, permanent hypocalcemia in 1 (3.7%) patient, and surgical site infection in 1 (3.7%) patient. Conclusion. Preoperative TPE is an alternative treatment option for thyrotoxic patients. This is an especially effective treatment for patients with inadequate response or adverse reaction to antithyroid drugs or patients who need urgent surgery for thyroid storm.

(2014) Yabanoglu, H.; Karagulle, E.; Belli, S.; Turk, E.; https://orcid.org/0000-0002-8522-4956; https://orcid.org/0000-0003-4766-3373; 24720139; C-6247-2017; AAJ-5609-2021
Purpose : The aim of our study was to assess our modified Dufourmentel flap outcomes in a standardized patient group (a symptom duration of equal to or greater than 60 months, presence of equal to or more than 3 sinus ostia or presence of sinus ostia fistulized equal to or greater than 2 cm laterally, and a normal body mass index) with extensive pilonidal sinus. Methods : Patients who were diagnosed with chronic pilonidal sinus disease and gave consent to surgical repair with modified Dufourmentel flap were enrolled. Patients were assessed with respect to age, sex, body mass index, presenting symptom, symptom duration, number of previous operations, number of sinus ostia, length of flap rims, depth of inter-gluteal sulcus, distance of sinus from anus, duration of operation, time of drain removal, length of hospital stay, early postoperative complications, postoperative pain, loss of labor, length of follow-up, and recurrences. Results : A total of 42 patients were enrolled. Average duration of presenting symptoms was 64.4 +/- 4.7 months and average length of follow-up was 29.4 +/- 3.6 months. Average length of hospital stay was 4.2 +/- 0.8 days, and time to return to work was 16.3 +/- 2.1 days. Two patients (4.7%) developed postoperative wound infection, one patient (2.4%) developed seroma, and three patients (7.1%) had wound dehiscence. There was no recurrence. Conclusion : Modified Dufourmentel flap application can be safely used in the treatment of extensive pilonidal sinus disease.
Results of Surgical Treatment of Anterior Abdominal Wall Desmoid Tumours: 13 Cases Reviewed with Literature
(2014) Yabanoglu, H.; Karagulle, E.; Aytac, H. O.; Caliskan, K.; Canpolat, T.; Koc, Z.; Akdur, A. C.; Moray, G.; Haberal, M.; https://orcid.org/0000-0002-1161-3369; https://orcid.org/0000-0002-8522-4956; https://orcid.org/0000-0002-3583-9282; https://orcid.org/0000-0002-8767-5021; https://orcid.org/0000-0003-0987-1980; https://orcid.org/0000-0002-8726-3369; https://orcid.org/0000-0003-2498-7287; https://orcid.org/0000-0002-3462-7632; 26021684; AAJ-7865-2021; C-6247-2017; AAJ-7913-2021; AAJ-7201-2021; AAK-8107-2021; S-8384-2016; AAA-3068-2021; AAE-1041-2021; AAJ-8097-2021
Background : We retrospectively evaluated the results of surgical treatment for anterior abdominal wall desmoid tumours. Methods : Records for 13 patients operated on for desmoid tumours from 1997-2013 were searched for age, gender, abdominal/pelvic surgical history, pregnancy, Gardner's syndrome, pre-operative radiological examinations, tumour size, multifocality, surgical procedure, tumour presence at surgical margins, recurrence, morbidity, and mortality. Local recurrence-free survival probabilities were estimated by the Kaplan-Meier method and stratified by various clinicopathological variables. Results : There were 11 female (84,6%) and 2 male (15,4%) patients with a median age of 36 years. Seven (53,8%) patients had previous abdominal/pelvic surgery, five (38,5%) had a history of pregnancy, and one (7,6%) had Gardner's Syndrome. Two (15,3%) patients had multifocality on their pre-operative radiological examinations. Mean tumour diameter was 4,6 cm (SD 3,2 cm; range 2-12 cm). After the excision of the masses in five (38,5%) patients, synthetic materials were used to close the abdominal wall defects. Two (15,3%) patients with positive surgical margins after surgery were re-operated. Three (23%) patients required a second surgical intervention after the mass excisions were performed. Mean follow-up time was 56,7 months. Recurrence was observed in three patients during follow-up. Increased tumour size, history of previous abdominal/pelvic surgery, and the presence of multifocality had a negative effect on local recurrence-free survival. There was no mortality during follow-up. Conclusions : Desmoid tumours are characterized by high recurrence, even after proper surgical excisions. Preoperative differential diagnoses of these tumours should be done and a post-operative follow-up protocol should be followed.
