Item Effect of Topical Platelet-Rich Plasma on Burn Healing After Partial-Thickness Burn Injury(2016) Ozcelik, Umit; Ekici, Yahya; Bircan, Huseyin Yuce; Aydogan, Cem; Turkoglu, Suna; Ozen, Ozlem; Moray, Gokhan; Haberal, Mehmet; 27262706Background: To investigate the effects of platelet-rich plasma on tissue maturation and burn healing in an experimental partial-thickness burn injury model. Material/Methods: Thirty Wistar albino rats were divided into 3 groups of 10 rats each. Group 1 (platelet-rich plasma group) was exposed to burn injury and topical platelet-rich plasma was applied. Group 2 (control group) was exposed to burn injury only. Group 3 (blood donor group) was used as blood donors for platelet-rich plasma. The rats were killed on the seventh day after burn injury. Tissue hydroxyproline levels were measured and histopathologic changes were examined. Results: Hydroxyproline levels were significantly higher in the platelet-rich plasma group than in the control group (P=.03). Histopathologically, there was significantly less inflammatory cell infiltration (P=.005) and there were no statistically significant differences between groups in fibroblast development, collagen production, vessel proliferations, or epithelization. Conclusions: Platelet-rich plasma seems to partially improve burn healing in this experimental burn injury model. As an initial conclusion, it appears that platelet-rich plasma can be used in humans, although further studies should be performed with this type of treatment.Item Arterial complication of irreversible electroporation procedure for locally advanced pancreatic cancer(2016) Ekici, Yahya; Tezcaner, Tugan; Aydin, Huseyin Onur; Boyvat, Fatih; Moray, Gokhan; 0000-0003-3795-5794; 0000-0003-2498-7287; 0000-0002-3641-8674; 27795815; S-8185-2018; AAE-1041-2021; M-1422-2019; AAD-9865-2021; F-4230-2011Irreversible electroporation (IRE) is a non-thermal ablation technique used especially in locally advanced pancreatic carcinomas that are considered surgically unresectable. We present the first case of acute superior mesenteric artery (SMA) occlusion secondary to pancreatic IRE procedure that has not been reported before in the literature. A 66-year-old man underwent neoadjuvant chemoradiotherapy for locally advanced pancreatic ductal adenocarcinoma. IRE procedure was applied to the patient during laparotomy under general anesthesia. After finishing the procedure, an acute intestinal ischemia was detected. A conventional vascular angiography was performed and a metallic stent was successfully placed to the SMA and blood flow was maintained. It is important to be careful in such cases of tumor involvement of SMA when evaluating for IRE procedure of pancreatic tumor.Item Laparoscopic spleen-preserving distal pancreatectomy for a primary hydatid cyst mimicking a mucinous cystic neoplasia(2017) Tezcaner, Tugan; Ekici, Yahya; Aydin, Onur Huseyin; Barit, Gonca; Moray, Gokhan; 0000-0003-2498-7287; 0000-0002-3641-8674; 0000-0003-3795-5794; 28281482; AAE-1041-2021; AAD-9865-2021; M-1422-2019; S-8185-2018Pancreatic hydatid cysts are fairly rare. The disease can be encountered concurrently with systemic involvement or as an isolated pancreatic involvement. We report the first case of spleen-preserving laparoscopic distal pancreatectomy for a pancreatic hydatid cyst. There was no complication or recurrence. A 55-year-old woman was admitted to our centre with epigastric and back pain. Upper abdominal magnetic resonance imaging revealed a solitary cystic lesion with septations at the pancreatic tail level measuring 24 mm x 18 mm, which was initially thought to be a pancreatic mucinous cystic neoplasia. She underwent laparoscopic spleen-preserving distal pancreatectomy and cholecystectomy. Her post-operative course was uneventful and histopathological examination revealed a hydatid cyst in the pancreatic tail.
