    One of the Rare Causes of Acute Abdomen Leading to Subileus: Jejunal Diverticulitis
    (2016) Aydin, Elcin; Yerli, Hasan; Avci, Tevfik; Yilmaz, Tugbahan; Gulay, Huseyin; 27308082
    Background: Jejunal diverticulitis is one of the rare causes of acute abdomen generally seen in the elderly. Jejunal diverticulosis was defined as the herniation of the mucosa and the submucosa from the inside of the muscular layer of the bowel wall on the mesenteric side of the intestine. Case Report: We presented the intraoperative and pathological findings of a 69-year-old male patient who had presented with complaints about abdominal pain, nausea, and vomiting and been operated upon due to subileus and peritonitis induced by large-sized jejunal diverticulitis, along with his computed tomography (CT) findings. Conclusion: Jejunal diverticulitis is uncommon and may be a disease which might be difficult to diagnose when it develops on the basis of the large-sized diverticula resembling intestinal ansae. To the best of our knowledge, the computed tomography and intraoperative findings of a case in which partial resection is applied to the jejunum due to subileus have not been previously presented in the literature.

    EFFECTS OF LOWER GASTROINTESTINAL TRACT SURGERY ON SURVIVAL IN ELDERLY AND OCTOGENARIAN PATIENTS
    (2018) Aydin, Huseyin Onur; Avci, Tevfik; Tezcaner, Tugan; Karagulle, Erdal; Yildirim, Sedat; 0000-0003-3795-5794; 0000-0002-8522-4956; 0000-0002-3641-8674; 0000-0001-5225-959X; 0000-0002-5735-4315; S-8185-2018; C-6247-2017; AAD-9865-2021; AAF-1698-2021; AAF-4610-2019
    Introduction: Life expectancy has significantly increased in the last decade. The decision to perform surgery has always been challenging in elderly patients. We aimed to evaluate outcomes in patients who underwent surgery for lower gastrointestinal tract diseases and investigate factors influencing morbidity and mortality, particularly in octogenarian patients, and the effects of age on prognosis and survival in the postoperative period. Materials and Method: This study included patients aged >= 70 years who underwent lower gastrointestinal tract surgery; patients were divided into three groups as 70-75 years, 75-79 years, and >= 80 years. Age, gender, type of surgery, ASA score, length of hospital stay, morbidity, 30-day mortality, and overall survival were evaluated. Results: The surgery was performed to 598 patients due to lower gastrointestinal tract diseases. There was a significant increase in the ASA score with increasing age (Chi-square=35.472; p<0.001). The survival rate was significantly higher in patients with malignancies than in those with benign diseases, and in patients who underwent elective surgery than in those who underwent emergency surgery (p<0.001). When patients were examined according to age groups, the overall survival was similar across groups (p=0.217). Conclusion: There was no significant difference between octogenarian and younger patients for complications and survival. Thus, planned surgical interventions in elderly patients will not negatively affect survival and surgical interventions and can be safely performed in these patients.

    Retrospective Analysis of Patients with Synchronous Primary Breast and Thyroid Carcinoma
    (2018) Arer, Ilker Murat; Yabanoglu, Hakan; Kus, Murat; Aldur, Aydincan; Avci, Tevfik; 0000-0002-8726-3369; 0000-0002-1161-3369; 0000-0001-5225-959X; 0000-0001-6529-7579; 29774315; AAA-3068-2021; AAJ-7865-2021; AAF-1698-2021; AAJ-7870-2021
    Objective: Breast and thyroid cancers are commonly encountered malignancies. Increased risk of breast cancer in follow-up period of thyroid cancer or vice versa has been reported. However, they have some associations, synchronous presentation of these tumors is rare. We presented 12 patients diagnosed as breast and thyroid cancer and treated at the same time. Materials and Methods: Mastectomy and thyroidectomy were performed in 19 patients at the same time. 7 patients were excluded because of benign thyroid pathology. Therefore 12 patients who had diagnosis of synchronous breast and thyroid cancer were included. Data regarding clinical, pathological, treatment and prognostic factors was retrospectively analyzed. Results: Total thyroidectomy was performed in all patients. The mean age of patients was 54 years (min. 44-max. 70). Only one patient was male. Thyroid pathology was detected preoperatively by FDG PET-CT scan in 11 patients. Breast reconstruction was performed in three patients. The most commonly seen thyroid malignancy was papillary thyroid carcinoma. Postoperative complication rate was 33.3%. Adjuvant chemotherapy was given in 11 patients whereas one patient received adjuvant radiotherapy. Conclusion: Although synchronous presentation of breast and thyroid cancer is rare, surgical treatment of both of these tumors can be safely performed at the same time. Association of these tumors should be evaluated by large scaled studies.
