    Autoimmune Pancreatitis and Treatment Approaches with Case Reports
    (Aves Yayincilik, 2012) Unalp, Omer; Erol, Varlik; Yeniay, Levent; Ozturk, Safak; Coker, Ahmet
    Objective: In this study, we aimed to review retrospectively the data of 10 patient who were treated and followed-up in our clinic and to review the current approaches in the diagnosis and treatment of autoimmune pancreatitis (AIP). Material and Methods: We reviewed 10 patients retrospectively who were operated on and had the diagnosis of AIP histopathologically in the Ege University School of Medicine Department of General Surgery. Results: Between June 2001-November 2010, 10 patients who were diagnosed as AIP were examined retrospectively. Radiologically, a pancreatic mass was found in the pancreatic head with ultrasound in 7 (70%) of 10 patients and suspicious lesions were identified in the head of the pancreas in 3 (30%) patients. All patients were operated on in our clinic with the preliminary diagnosis of pancreatic head tumor; 8 patients underwent Whipple's procedure, 1 patient underwent pylorus preserving pancreaticoduodenectomy, and in 1 patient an exploratory pancreatic biopsy (frozen section) was carried out. Conclusion: Autoimmune pancreatitis is a disease with increasing incidence and characterized by lymphoplasmocytic cell infiltration and fibrosis. Patients with a pancreatic mass, if there is an autoimmune disease or chronic pancreatitis suspected in the detailed history, it is necessary to evaluate patients in terms of AIP serologically to protect the patients from an incoorectng diagnosis and morbidity of surgery.

    Inflammatory myofibroblastic tumour
    (Cma-Canadian Medical Assoc, 2009) Firat, Ozgur; Ozturk, Safak; Akalin, Taner; Coker, Ahmet
    Inflammatory myofibroblastic tumours (IMTs), previously accepted as a subtype of the group of tumours called inflammatory pseudotumours, are now recognized to comprise their own, discrete diagnosis. Since IMTs can arise from various anatomic locations,(1,2) they concern almost every subspecialty in surgical oncology. The management of these tumours can be challenging because there are no established medical treatment protocols, and tumours can be irresectable owing to their proximity to vital structures. We present the case of a patient whose IMT was removed after 2 trials of chemotherapy after 2 unsuccessful surgeries.

    Prognostic factors in acute mesenteric ischemia and evaluation with multiple logistic regression analysis effecting morbidity and mortality
    (Index Copernicus Int, 2021) Ozturk, Safak; Unver, Mutlu; Ozdemir, Murat; Bozbiyik, Osman; Turk, Yigit; Firat, Ozgur; Caliskan, Cemil
    Background: Acute mesenteric ischemia (AMI) is a catastrophic abdominal emergency characterized by sudden critical interruption to the intestinal blood flow which commonly leads to bowel infarction and death. AMI still has a poor prognosis with an in-hospital mortality rate of 50-69%. This high mortality rate is related to the delay in diagnosis which is often difficult and overlooked. Early intervention is crucial and gives a chance for intestinal viability. Methods: The charts of 140 patients who were hospitalized with AMI between May 1997 and August 2013 in Ege University Faculty of Medicine, Department of General Surgery were retrospectively reviewed. Demographical and clinical features of patients constituting the best predictors of morbidity and mortality were evaluated with Multiple Logistic Regression analysis by Enter method after adjustment for all possible confounding factors. Results: Out of 140 patients, 77 were men (55%) and 63 were women (45%). The mean age was 66.6 +/- 14.5 (16-94) years. Demographical findings, comorbidities, ASA scores, drugs used for mesenteric ischemia and diagnostic imaging materials were summarized. The most common comorbidities were cardiac problems (42.9%). Twenty-seven (19.3%) patients had diabetes mellitus. The median ASA score was 3. Abdominal computed tomography (CT) was the most commonly used imaging modality and it was performed in 119 (85%) patients. Twenty-five (17.9%) patients were in shock and 48 (34.3%) had acidosis. The time of delay between the onset of acute abdominal pain to surgery was <12 hours in 14 patients (10.0%), 12 to 24 hours in 46 patients (32.9%), and >24 hours in 80 patients (57.1%). The most common etiology in AMI was thrombus, in 69 patients (49.3%). The most affected or involved organ was both small and large bowel - in 80 patients (57.1%) in total. The most commonly performed surgery was small bowel resection - in 42 patients (30%).As many as 127 (90.7%) of all patients underwent surgery and 18 (12.9%) patients underwent a second-look laparotomy. Small bowel length of less than 100 cm was recorded in 46 patients (32.9%). The length of hospital stay was 7 days (1-90 days). Morbidities were found in 51 patients (36.4%) and death in 74 patients (52.9%). Conclusion: The purpose of this study was to evaluate the prognostic factors of AMI to better understand it and optimize both medical and surgical management with improvement of treatment results. We suggested that the diagnosis of AMI should be based on suspicion of a clinician only and that laparotomy should be performed as soon as possible, before the onset of the clinical signs of peritonitis. Age and time of delay between the onset of acute abdominal pain and surgery longer than 24 hours are the most important prognostic factors for mortality in patients presenting with shock and acidosis.

    Prognostic Factors in Peptic Ulcer Perforations: A Retrospective 14-Year Study
    (Int College Of Surgeons, 2015) Unver, Mutlu; Firat, Ozgur; Unalp, Omer Vedat; Uguz, Alper; Gumus, Tufan; Sezer, Taylan Ozgur; Ozturk, Safak; Yoldas, Tayfun; Ersin, Sinan; Guler, Adem
    Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

    A Rare Cause of Colonic Obstruction ''Colonic Intussusception'': Report of Two Cases
    (Hindawi Ltd, 2015) Yoldas, Tayfun; Karaca, Avni Can; Ozturk, Safak; Unver, Mutlu; Caliskan, Cemil; Korkut, Mustafa Ali
    Colocolic intussusceptions are rare clinical entities in adults and almost always caused by a leading lesion which often warrants resection. Mostly being malignant, the leading lesions are rarely benign lesions where intraluminal lipomas are the most frequent among them. Most adult intussusceptions require surgical resection owing to two major reasons: common presence of a leading lesion and significantly high risk of malignancy-reaching as high as 65% regardless of the anatomic site-of the leading lesion. Resection of the affected segment is usually the treatment of choice, since preoperative diagnosis of the lesion is usually ineffective and most leading lesions are malignant. This paper represents two cases of adult colocolic intussusception caused by intraluminal lipomas with a brief review of the literature.
