Background: Pancreatic neuroendocrine tumors (pNET) are rare diseases and surgical treatment is promising. In this study, we retrospectively analyzed the patients who underwent surgical treatment for pancreatic neuroendocrine tumor in our hospital in the last 11 years; We aimed to present our findings to the literature. Materials and Methods: The files of the patients who applied for pNET between January 2011 and March 2022 were retrospectively analyzed. Patients with multiple data deficiencies, who did not undergo surgery, and who were younger than 18 years of age were excluded from the study. The patients were evaluated in terms of age, gender, type of operation, tumor size, type and histological features, hospital stay, recurrent disease and survival. Results: Of the 33 patients included in the study, 13 were female and 20 were male, and the median age was 56 (18-86). There were 8 patients with functional tumors, one was somatostatinoma and the others were insulinomas. Enucleation in 7 of the patients; Pancreatectomy was performed in 26 of them. There were three patients whose main lesion was adenocarcinoma and serous cystadenoma, who underwent resection and whose specimen pathology had incidental pNET. We had 23, 7 and 3 patients with grade 1,2 and 3 tumors, respectively. The median value of tumor diameter was 24 (3-80) mm. The median value for hospital stay was 7 (2-50) days. The median value of follow-up was 24 (1-71) months; disease-free survival was 14 (1-71) months. Conclusions: pNETs are a rare disease that can be detected incidentally and should be carefully managed. Studies with larger series are needed to reach a consensus on the surgical and conservative treatment of pNET. [ABSTRACT FROM AUTHOR]

Objective: In this study we aimed to evaluate the results of pathology that patients undergoing laparoscopic and open appendectomy with suspected appendicitis from August 2012 to August 2014. Material and Method: In this study data from 131 patients undergoing laparoscopic and open appendectomy between August 2012 and August 2014 in Van Training and Research Hospital were examined retrospectively for demographic characteristics. Results: In the laparoscopic appendectomy group handmade endoloop technique was used for closing the base of the appendix. Mc Burney's incision was used for open appendectomy. 47% of patients was female (n=61), 53% of patients were male (n=69). The average age of the patients was 27.7 years. According to surgical technique, open appendectomy was performed 15% (n=20), laparoscopic appendectomy was performed 85% (n=110). Postoperative drainage tube was put to 15% of patients (n=20). Wound infection was seen in 4 open appendectomy performed patients (20%). Laparoscopic appendectomy was associated with a shorter hospital stay (2.2 days vs 2.8 days). When the pathology results are analyzed, 2 malignancies are revealed (1,5%), 1 carcinoid tumor, 1 neuroendocrine tumor. After pathology results hemicolectomy was performed. Conclusion: Appendectomy is the most frequently performed surgery, even if macroscopic pathology is not present the risk of malignancy can not be underestimated. [ABSTRACT FROM AUTHOR]
