Item Comparison of Mortality Rates in Patients Waiting for Liver Transplant and Patients With Colorectal Metastatic Tumors(2022) Erkent, Murathan; Aydin, H. Onur; Tezcaner, Tugan; Avci, Tevfik; Kavasoglu, Lara; Soy, Ebru H. Ayvazoglu; Yildirim, Sedat; Haberal, Mehmet; 0000-0002-3592-5092; 0000-0002-0664-5147; 0000-0002-0993-9917; 0000-0002-3462-7632; 35352633; CAA-2756-2022; AAJ-8219-2021; AAC-5566-2019; AAJ-8097-2021Objectives: We aimed to identify outcomes of liver surgery in patients with hepatocellular carcinoma and colorectal cancer, which result in primary and secondary liver tumors. Materials and Methods: Our study included 51 patients with colorectal cancer and liver metastases and 63 patients with hepatocellular carcinoma who were prepared for liver transplant due to cirrhosis who underwent hepatic resection or local ablation treatments; patients were seen between January 2011 and December 2021. Results: Most patients with colorectal cancer were men (58.8%). Mean age was 65.76 +/- 13.818 years (range, 27-88 y). Most patients had planned, elective surgery (86.3%). Neoadjuvant chemotherapy was administered to 58.8% of patients. The most common location of metastasis in the liver was in the right lobe (43.1%), and the most common surgery was low anterior resection (17 patients). During simultaneous liver surgery, 31 patients required metastasectomy and 7 patients required radiofrequency ablation plus metastasectomy. No deaths occurred in the early posttransplant period, and cumulative survival was 82.624 +/- 7.962 months. Disease-free survival was 45.2 +/- 7.495 months. Most patients with hepatocellular carcinoma were men (82.5%). Mean age was 58.73 +/- 17.428 years. Hepatocellular carcinoma lesions were mostly located in both the right and left lobes (23.8%). In the hepatocellular cancer group, 60.3% had transarterial chemoembolization and 42.9% had radiofrequency ablation. The primary surgical resection was metastasectomy (17.9%) because of multiple localized lesions. Median follow-up was 22 months (range, 1-126 mo). Overall survival was 101.898 +/- 7.169 months, with 10-year overall survival of 38%. Disease-free survival was 74.081 +/- 8.732 months, with 1-year and 5-year disease-free survival of 90.5% and 54%. Conclusions: Better survival was shown in patients with hepatocellular carcinoma than in patients with colorectal cancer. Therefore, more aggressive treatment options, as used in hepatocellular carcinoma, including liver transplant, may be options for patients with colorectal cancer.Item Hand-made Extracorporeal Knotting versus Hem-o-Lok Clip for Stump Closure in Laparoscopic Appendectomy(2019) Arer, Ilker Murat; Avci, Tevfik; Yabanoglu, Hakan; 31839096Objective: To compare hand-made extracorporeal knotting and hem-o-lok clip for the closure of appendix stump regarding safety, complications and cost-effectiveness. Study Design: Descriptive study. Place and Duration of Study: Baskent University Adana Teaching and Research Center, between January 2010 and December 2016. Methodology: A total of 287 patients, who underwent laparoscopic appendectomy, were enrolled in this study. Patients were divided into hand-made extracorporeal knotting and hem-o-lok clip groups. Patients were compared according to age, gender, duration of symptoms, serum leukocyte count, American Society of Anesthesiologists (ASA) score, intraoperative findings, operation time, hospital stay, pathology report and complications. Results: Of 287 patients, 149 (51.9%) were female and 138 (48.1%) were male. The mean age was found 34.9 years. No statistical difference was observed between groups according to age, gender, duration of symptoms, serum leukocyte count, ASA score, operation time and hospital stay. Intraoperative findings were different between groups (p<0.05). Overall postoperative complication rate was 6.6%. No statistical difference was observed regarding complications Conclusion: Both hand-made extracorporeal knotting and hem-o-lok clips can be used for stump closure in laparoscopic appendectomy. Hand-made extracorporeal knotting is an effective, safe and costeffective method alternative to hem-o-lok clips.Item One of the Rare Causes of Acute Abdomen Leading to Subileus: Jejunal Diverticulitis(2016) Aydin, Elcin; Yerli, Hasan; Avci, Tevfik; Yilmaz, Tugbahan; Gulay, Huseyin; 27308082Background: 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.Item Partial Splenic Torsion in situ: Revealed by Ultrasound and Computed Tomography(2018) Haberal, K. Murat; Bayramoglu, Mert; Kahraman, Gokhan; Avci, Tevfik; 0000-0001-5225-959X; 0000-0002-8211-4065; 30065530; AAF-1698-2021; R-9398-2019We present a case of acute abdominal pain due to partial torsion of spleen located in its own normal anatomical position in a 20-year-old woman, diagnosed by ultrasound and confirmed on computed tomography and treated laparoscopically.Item 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-7870-2021Objective: 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.
