Öğe Acute Mesenteric Ischemia: Clinical Experience(Aves, 2009) Aslan, Ahmet; Temiz, Muhyittin; Semerci, Ersan; Ozkan, Orhan Veli; Yetim, Ibrahim; Fansa, Iyad; Beyaz, FikretBACKGROUND: Acute mesenteric ischemia (AMI) is a life threatening vascular emergency which requires prompt diagnosis and treatment. The prevention of this cause of high mortality and morbidity depends on early clinical suspicion end timely intervention. In the present study we aimed to analyze the acute mesenteric ischemia cases treated in Mustafa Kemal University Department of General Surgery between January 2004 and December 2008. MATERIAL/METHODS: The clinic records of all the patients who underwent surgical treatment for AMI between January 1, 2004, and December 2008, were retrospectively reviewed. The data from operative records, postoperative complications, mortality, and hospital stay were recorded. RESULTS: The study group included 18 patients. Mean age was 69. There was comorbidity in all patients and cardiac disease and hypertension were the most common ones. The most common laboratory abnormalities were leukocytes, hypoalbuminemia, hyperamylasemia. There was superiorly vascular necrosis in 16 patients; inferior vascular necrosis in one patient. One patient had non occlusive mesenteric ischemia. Segmentery resection was performed to 13 patients. Abdominoperineal resection was performed to the patient with inferior mesenter artery occlusion. We performed duodenotransversostomy on two patients and only laparotomy on two patients. Re-operation was required in 5 patients. Causes of death were multiorgan insufficiency in 7 cases, cardiac death in 2 cases. One patient died due to short intestine syndrome. CONCLUSION: Acute mesenteric ischemia is highly mortal emergency which should always be suspected in elderly patients with cardiac disease suffering from abdominal pain.Öğe The Analysis of Mean Platelet Volume and Platelet Distribution Width Levels in Appendicitis(Springer India, 2015) Aydogan, Akin; Akkucuk, Seckin; Arica, Secil; Motor, Sedat; Karakus, Ali; Ozkan, Orhan Veli; Yetim, IbrahimWe aimed to analyze the diagnostic value of mean platelet volume and platelet distribution width, which are also known as the markers of platelet count, in acute and perforated appendicitis. The data of 202 patients who applied to general surgery clinic in Mustafa Kemal University Hospital from 2007 to 2012 with acute appendicitis were analyzed retrospectively. The findings were separated to two groups due to the perforation status (perforated vs. non-perforated). Age, sex, leukocyte, hemoglobin, hematocrit, mean platelet volume, and platelet distribution width were examined. The mean age of the patients was 35.8. Twenty-one of all cases were perforated appendicitis (10.4 %), and the rest was acute appendicitis (non-perforated) (n=181, 89.6 %). The mean platelet volume value was 9.8 +/- 2.1 fL; mean thrombocyte count, 340.9x10(9)/L; and mean platelet distribution width value, 18.3 %. There were statistically significant differences between sex and age, hemoglobin, hematocrit, leukocyte, mean platelet volume, and platelet distribution width. There was a positive correlation between mean platelet volume, platelet distribution width, and platelet. Age, leukocyte, platelet, mean platelet volume, and platelet distribution width were higher in cases with perforation as a comparison with non-perforated cases. We think that mean platelet volume and platelet distribution width may be valuable markers to detect the risk of perforation in early periods of acute appendicitis.Öğe BILATERAL PRIMARY BREAST LYMPHOMA: A RARE CASE(Aves, 2011) Yetim, Ibrahim; Yetim, Tulin Durgun; Ozkan, Orhan Veli; Diner, Guvenc; Savas, Nazan; Davran, Ramazan; Helvaci, RahmiPrimary non Hodgkin's lymphoma of the breast is rare. Bilateral involvement of the breasts is even morerare. Lymphomas are divided into two groups: Hodgkin's Lymphoma and non Hodgkin's lymphoma. Diffuse large cell non Hodgkin's lymphoma is the most common type. A 56 year old female presented with masses in both breasts. An excisional biopsy was obtained from both tumoral masses. Histopathological assessment revealed diffuse large cell non Hodgkin's lymphoma and chemotherapy was started. Here we present the case of bilateral primary breast lymphoma while discussing clinical characteristics, treatment modalities and the outcomes.Öğe Cholethorax (Bilious Effusion in the Thorax): An Unusual Complication of Laparoscopic Cholecystectomy(Acad Medical Sciences I R Iran, 2013) Aydogan, Akin; Erden, Ersin Sukru; Akkucuk, Seckin; Davran, Ramazan; Yetim, Ibrahim; Ozkan, Orhan VeliCholethorax or bilious effusion in the thorax, is a rare condition in which bile passes into the pleural space from the abdominal cavity, necessitating urgent treatment. In this article, we present a case of cholethorax as a complication of laparoscopic cholecystectomy (LC). The patient underwent a LC due to the presence of a gallbladder polyp. The clip attached to the Hartman opened, and the abdominal cavity became contaminated with binary fluid. Postoperatively, the patient experienced severe right upper quadrant pain and dyspnea. Both the posteroanterior (PA) chest radiography and thoracic computed tomography (CT) were remarkable for marked effusion in the right hemithorax. The patient underwent thoracentesis which resulted in the removal of 250 cc bilious pleural effusion. The bilirubin level of the pleural fluid was 9.1 mg/dL. Following thoracentesis, the patient experienced significant improvement in dyspnea and pain. The patient was discharged without any complications on the seventh day postoperatively. Cholethorax may occur as a result of diaphragmatic injuries secondary to a laparoscopic instrument and can be successfully treated by a thoracentesis.Öğe CONCOMITANT PRESENCE OF BREAST CANCER AND CHRONIC LYMPHOCYTIC LEUKEMIA(Aves, 2011) Akcakaya, Adem; Ozkan, Orhan Veli; Okan, Ismail; Sahin, Mustafa; Tuzlali, Sitki; Dasiran, FatihCertain malignancies may occur concomitantly or consecutively.. We present a female patient with breast carcinoma who had chronic leukemia concurrently with breast cancer.. She underwent a modified radical mastectomy. The histopathologic examination of both mastectomy and axillary specimen revealed diffuse, atypical lymphoid proliferation and microscopic foci of lymphocytic infiltrations beside the typical breast carcinoma findings. Lymphocytes taken from peripheral blood and bone marrow aspirates were stained with CD5 and CD20. The diagnosis of chronic lymphocytic leukemia (CLL) was confirmed. CLL was diagnosed as a synchronous malignancy together with breast carcinoma. It should be kept in mind that breast carcinoma may occur concomitantly with other malignancies especially CLL. Second malignancies occur with an increased frequency in patients with CLL, mainly because of the immune defects associated with this disease.Öğe Delayed diagnosis of traumatic diaphragmatic hernia may cause colonic perforation: A case report(2009) Ozkan, Orhan Veli; Semerci, Ersan; Yetim, Ibrahim; Davran, Ramazan; Diner, Guvenc; Paltaci, IlhanEarly diagnosis of diaphragmatic rupture after traumas may be difficult, and delayed diagnosis may result in increased morbidity and mortality. This paper describes the case of a 32-year-old man who experienced a traffic accident and had diagnosis of traumatic diaphragmatic hernia nearly four months later. The patient was referred to our emergency room suffering from ileus symptoms. Physical examination demonstrated an apparent abdominal distention, tenderness at the upper abdominal quadrants, rebound, and defense. Thoraco-abdominal X-rays and computerized tomography imaging demonstrated intestinal segments with air-fluid levels in thorax. Laparotomy was performed after a preoperative diagnosis of a strangulated-diaphragmatic hernia. At abdominal exploration, it was found that transverse colon and omentum entered into thorax through diaphragmatic defect located at the left diaphragm. Herniating colon segment was complicated with ischemic necrosis and perforation. In conclusion, colon necrosis and perforation may develop when early diagnosis of diaphragmatic ruptures are missed. © 2009 Ozkan et al.; licensee Cases Network Ltd.Öğe Effects of ?-Glucan Pretreatment on Acetylsalicylic Acid-Induced Gastric Damage: An Experimental Study in Rats(Elsevier Science Inc, 2010) Ozkan, Orhan Veli; Ozturk, Oktay Hasan; Aydin, Mehmet; Yilmaz, Nigar; Yetim, Ibrahim; Nacar, Ahmet; Oktar, SuleymanBACKGROUND: NSAIDs have been found to induce gastrointestinal tract damage. Recently, it has been suggested that this might be mediated by lipid peroxidation. OBJECTIVE: The aim of this study was to assess the potential protective effects of beta-glucan against acetylsalicylic acid (ASA)-induced gastric damage by means of its antioxidant capacity in an experimental rat model. METHODS: Thirty-two male Wistar albino rats (200-250 g) were randomized into 4 groups consisting of 8 rats each. The beta-glucan group received 50 mg/kg beta-glucan once a day for 10 days and 30 minutes before anesthesia. The ASA group received saline once a day for 10 days and 300 mg/kg (20 mg/mL) ASA as a single dose, 4 hours before anesthesia. The ASA+beta-glucan group was administered 50 mg/kg beta-glucan once a day for 10 days and 30 minutes before anesthesia. Additionally, 300 mg/kg (20 mg/mL) ASA was administered as a single dose, 4 hours before anesthesia. The control group received saline once a day for 10 days and 30 minutes before anesthesia. All medications were administered by intragastric gavage. The stomach from each rat was dissected and divided into 2 parts for histologic and biochemical analysis. Gastric tissue malondialdehyde (MDA), nitric oxide (NO) levels, catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activities were determined for oxidative parameter analysis. RESULTS: The gastroprotective and antioxidant effects of beta-glucan appeared to attenuate the ASA-induced gastric tissue damage. Compared with the control group, MDA and NO levels and CAT and GSH-Px activities were significantly increased in the stomachs of ASA-treated rats (MDA, 4.12 [0.44] to 13.41 [1.05] mu mol/L; NO, 8.04 [7.25-9.10] vs 30.35 [22.34-37.95] mu mol/g protein; CAT, 0.050 [0.004] to 0.083 [0.003] k/g protein; GSH-Px, 0.57 [0.42-0.66] to 1.55 [1.19-1.76] U/L; all, P < 0.001), whereas SOD activity was significantly decreased in the same group (291 [29] to 124 [61 U/mL; P < 0.001). In the ASA+beta-glucan group, MDA and NO levels and CAT and GSH-Px activities were found to be significantly lower, while SOD activity was found to be significantly higher, in comparison with the ASA-treated group (all, P < 0.001). CONCLUSION: beta-Glucan appeared to attenuate the gastric damage caused by ASA in these rats.

Renal ischemia/reperfusion (I/R)-induced tubular epithelial cell injury, called ischemic acute renal failure, is associated with high mortality in humans. Protecting the kidney against I/R injury is very important during complicated renal operations, transplantation surgery, and anesthesia. Aim. The purpose of this study was to investigate and compare the efficiency of ketamine, thiopental, propofol, etomidate, and intralipid in reducing the injury induced by free radicals in a rat model of renal I/R. Method. Forty-two Wistar rats were divided into seven groups in our study. Rats in the sham group underwent laparotomy and waited for 120 minutes (min) without ischemia. Rats in the control group were given nothing with ischemia-reperfusion. Rats in the I/R groups were given ketamine (20 mg/kg), thiopental (20 mg/kg) propofol (25 mg/kg), etomidate (10 mg/kg) and 10% intralipid (250 mg/kg) intraperitoneally 15 min prior to the ischemia for 60 min, followed by reperfusion for 60 min. The blood samples and kidney tissues of the rats were obtained under anesthesia at the end of the reperfusion period. Biochemical malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), blood urea nitrogen (BUN), creatine (Cr), aspartate aminotransferase (AST) were determined, and histopathological analysis was performed with these samples. Results. MDA level was increased significantly in the control group (p 0.05). Histopathological findings of the control group confirmed that there was renal impairment by tubular cell swelling, interstitial edema, medullary congestion, and tubular dilatation. MDA levels were lower in the ketamine, thiopental, and propofol groups compared to the control group (p 0.05). In the thiopental and propofol groups, the levels of histopathological scores were significantly lower than control and etomidate groups in ischemia-reperfusion. Conclusion. Our results demonstrated that I/R injury was significantly reduced in the presence of propofol and thiopental. The protective effects of these drugs may belong to their antioxidant properties. These results may indicate that propofol and thiopental anesthesia protects against functional, biochemical, and morphological damage better than control in renal I/R injury.Öğe The Effects of Low-Dose Erythropoiesis-Stimulating Agents on Peritoneal Fibrosis Induced by Chemical Peritonitis and on Peritoneal Tissue MMP-2 and TIMP-2 Levels in Rats(Taylor & Francis Ltd, 2009) Yildirim, Ayse; Ozkan, Orhan Veli; Aslan, Ahmet; Koseoglu, Zikret; Borazan, AliAim. The objective of the present study was to investigate the effect of low-dose erytropoesis-stimulating agents (ESA) on the development of peritoneal fibrosis in chlorhexidine gluconate-induced peritoneal sclerosing rats and to assess the peritoneal tissue levels of MMP-2 and TIMP-2, which may be regarded as factors in the development of peritoneal fibrosis. Subjects and methods. Twenty-four Wistar albino rats were divided into three groups. The control group received 0.9% saline (3 ml/d) intraperitoneally, the CH group received 3 ml daily injections of 0.1% chlorhexidine gluconate (CH) intraperitoneally, and the CH+ESA group received 3 ml daily injections of 0.1% CH intraperitoneally and epoetin beta (3 x 20 IU/kg/week) subcutaneously. On the twenth-first day, rats were sacrificed, and parietal peritoneum samples were obtained from the left anterior abdominal wall. Pathological samples were examined using Hematoxyline & Eosin (HE) stains. The thickness, vascular proliferation, and inflammation were determined by light microscopy. MMP-2 and TIMP-2 were studied immunohistochemically by monoclonal antibody staining. Results. Inflammation, vascular proliferation, and fibrotic area percentages were not statistically significant between groups. Histopathologically control, CH, CH+ESA groups peritoneal thickness were 8.02 +/- 2.89, 146.74 +/- 26.1, and 48.12 +/- 16.8 micrometers, respectively. The decrease in thickness of parietal peritoneum in CH+ESA group was statistically significant when compared to CH. Immunohistochemically, interferon was shown to decrease MMP-2 expression on parietal peritoneum than group CH, but has no effect on TIMP-2. Discussion. Low-dose ESA histopatologically reduces peritoneal fibrosis induced by chlorhexidine gluconate. However, from dosage and duration points of view, we need extended clinical and experimental studies.Öğe Endoscopic retrograde cholangiopancreatography during pregnancy without radiation(Baishideng Publishing Group Inc, 2009) Akcakaya, Adem; Ozkan, Orhan Veli; Okan, Ismail; Kocaman, Orhan; Sahin, MustafaAim: To present our experience with pregnant patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) without using radiation, and to evaluate the acceptability of this alternative therapeutic pathway for ERCP during pregnancy. METHODS: Between 2000 and 2008, six pregnant women underwent seven ERCP procedures. ERCP was performed under mild sedoanalgesia induced with pethidine HCI and midazolam. The bile duct was cannulated with a guidewire through the papilla. A catheter was slid over the guidewire and bile aspiration and/or visualization of the bile oozing around the guidewire was used to confirm correct cannulation. Following sphincterotomy, the bile duct was cleared by balloon sweeping. When indicated, stents were placed. Confirmation of successful biliary cannulation and stone extraction was made by laboratory, radiological and clinical improvement. Neither fluoroscopy nor spot radiography was used during the procedure. RESULTS: The mean age of the patients was 28 years (range, 21-33 years). The mean gestational age for the fetus was 23 wk (range, 14-34 wk). Five patients underwent ERCP because of choledocholithiasis and/or choledocholithiasis-induced acute cholangitis. In one case, a stone was extracted after precut papillotomy with a needle-knife, since the stone was impacted. One patient had ERCP because of persistent biliary fistula after hepatic hydatid disease surgery. Following sphincterotomy, scoleces were removed from the common bile duct. Two weeks later, because of the absence of fistula closure, repeat ERCP was performed and a stent was placed. The fistula was closed after stent placement. Neither post-ERCP complications nor premature birth or abortion was seen. CONCLUSION: Non-radiation ERCP in experienced hands can be performed during pregnancy. Stent placement should be considered in cases for which complete common bile duct clearance is dubious because of a lack of visualization of the biliary tree. (C) 2009 The WJG Press and Baishideng.

Therefore, it is required for general surgeons to learn how to perform USG. This letter is written to open a discussion forum about ultrasonography teaching in general surgery resident training in Journal of National Surgery owned by Turkish Surgery Society, one of the most populated societies.Öğe Gossypiboma Causing Mechanical Intestinal Obstruction: A Case Report(Hindawi Ltd, 2012) Aydogan, Akin; Akkucuk, Seckin; Yetim, Ibrahim; Ozkan, Orhan Veli; Karcioglu, MuratIntroduction. Gossypiboma (GP) is a term used to express the mass resulting from forgotten cotton sponge in operations. Rarely, a transmural migration may occur into the gastrointestinal lumen without creating any defect by GP. Laparotomy or endoscopic removal may be required, by the way it can be taken out of the body itself by intestinal ways. In this study, we reported a case of mechanical intestinal obstruction causing GP. Case. The fifty-one-year-old female patient admitted to the emergency department with the complaints of mechanical intestinal obstruction and had a history of open cholecystectomy 20 years ago. There were the findings of intestinal obstruction in abdominal plain radiography and computerized tomography. The sponge that obstructed the lumen completely 40 cm proximal to the ileocecal valve was identified in the laparotomy with the diagnosis of brid ileus. The small intestine was closed over double-fold after removal of sponge. Transmural migration of abdominal-remained sponge was thought to be occurred without creating a defect after cholecystectomy. Postoperatively, the patient was discharged without having any problems at 4th day of hospitalization. Conclusion. Although it is a rare situation in routine clinical practice, GP should be considered as a differential diagnosis in the patients who had a diagnosis of mechanical intestinal obstruction, and laparotomy was applied before. As GP may lead to situations which cause mortality, all precautions should be taken to prevent it.Öğe Left paraduodenal hernia diagnosed preoperatively(Wiley-Blackwell Publishing, Inc, 2010) Okan, Ismail; Ozkan, Orhan Veli; Sahin, Mustafa; Bas, Gurhan; Alimoglu, Orhan[Abstract Not Available]Öğe Letrozole induces hepatotoxicity without causing oxidative stress: the protective effect of melatonin(Taylor & Francis Ltd, 2011) Aydin, Mehmet; Oktar, Suleyman; Ozkan, Orhan Veli; Alcin, Ergul; Ozturk, Oktay Hasan; Nacar, AhmetAim. The aim of this study was to determine the effects of letrozole (LTZ), an aromatase inhibitor (AI), and melatonin (MLT) on hepatic function and oxidative stress in female rats. Material and methods. A total of 32 female rats were divided equally into four groups (n = 8). Control group received saline (0.5 ml/day, oral gavage). LTZ was administered to rats by daily oral gavage at 1 mg/kg dose. LTZ + MLT group was given LTZ (1 mg/kg, oral gavage) plus MLT (0.5 mg/kg/day, s.c.). MLT group was given MLT (0.5 mg/kg/day) by s.c. injection. The activities of superoxide dismutase (SOD) and catalase (CAT) and malondialdehyde (MDA) levels were measured in liver tissue. Total antioxidant capacity (TAC), total oxidant status (TOS), ALT, AST, GGT, ALP, LDH, bilirubin, BUN, creatinine, total cholesterol (TC), high-density lipoprotein (HDL) and triglyceride (TG) were assayed in serum samples. Results. The oxidative stress, parameters did not differ between groups. LTZ administration increased hepatic function parameters such as AST, LDH, ALP, bilirubin and MLT improved the disturbances of hepatic function. LTZ caused minimal histological changes in liver tissue and MLT treatment reversed those dejenerations. Discussion. LTZ may cause hepatotoxicity without inducing oxidative stress and MLT restores hepatic activity.Öğe Mechanical lithotripsy and/or stenting in management of difficult common bile duct stones(Elsevier Science Bv, 2009) Akcakaya, Adem; Ozkan, Orhan Veli; Bas, Gurhan; Karakelleoglu, Atilla; Kocaman, Orhan; Okan, Ismail; Sahin, MustafaBACKGROUND: Mechanical lithotripsy and/or stent insertion is the alternative therapeutic approach in difficult endoscopic retrograde cholangiopancreatography (ERCP) case. This study was designed to investigate the appropriate treatment for extraction of bile duct stones in difficult cases of ERCP. METHODS: Between 2000 and 2008, 744 ERCP procedures were performed in 592 patients with choledocholithiasis in our endoscopy unit. The demographic features, and clinical and laboratory findings were collected from a prospectively held database. Bile duct calculi were extracted by basket and/or balloon catheter following ERCP and sphincterotomy. Patients with retained stones were regarded as difficult cases. These patients were treated with mechanical lithotripsy and those with incomplete clearance of stones underwent stent placement. RESULTS: Two hundred and forty-five patients (41%) were male and 347 (59%) were female with a mean age of 58 years (range 19-95 years). Stones were impacted in 27 patients (5%). Stone extraction was performed by basket and/or balloon catheter in 610 ERCP procedures, and lithotripsy was performed in 70 ERCP procedures. Forty-four patients underwent stent insertion, and 20 underwent stent replacement. Morbidity occurred in 39 patients (5%), with no mortality associated with the procedure. Hemorrhage occurred in 9 patients and basket impaction in 4. Mild pancreatitis and cholangitis developed in 12 and 11 patients, respectively. CONCLUSION: Difficult cases of bile duct stones can be treated successfully with lithotripsy, and a stent should be applied when the common bile duct cannot be cleared completely.Öğe Necrotizing pancreatitis with hypertriglyceridemia development result: A cese port(Derman Medical Publ, 2011) Yetim, Ibrahim; Ozkan, Orhan Veli; Diner, Guvenc; Yilmaz, Aydin; Gokce, Cumali; Kaya, HasanAcute pancreatitis due to hypertriglyceridemia is a relatively rare clinical entity. Acute pancreatic necrosis is a life threatening form of acute pancreatitis in which early recognition and treatment is important. Necrotising pancreatitis should be treated immediately. We presented a case of pancreatic necrosis due to hypert-riglyceridemia which required surgical intervention. We performed necro-sectomy. After surgery the patient recovered. We presented the case in order to mention necrotising pancreatitis arising from hypertriglyceridemia and requiring surgical exploration.Öğe A Physiologic Events' Cascade, Irritable Bowel Syndrome, is Significantly Associated with Chronic Gastritis, Hemorrhoid, Urolithiasis, and Depression(Elsevier Science Bv, 2007) Duru, Mehmet; Kuvandik, Guven; Ozkan, Orhan Veli; Helvaci, Mehmet Rami; Kaya, HasanObjectives: About one third of people report recurrent upper abdominal discomfort, and irritable bowel syndrome (IBS) is probably associated with most of the underlying pathologies. Materials and Methods: We took consecutive patients admitted to the Emergency Department because of upper abdominal discomfort. IBS is diagnosed according to Rome II criteria in the absence of red flag symptoms, which are not typical for IBS. Other underlying causes of upper abdominal discomfort were detected and results were compaired between the cases with and without IBS. Results: One hundred and twenty patients with IBS and 138 patients without were studied. Although 61.6% (n=74) of the IBS cases were female, this ratio was 42.0% (n=58) in patients without IBS (p<0.001). On the other hand, chronic gastritis (CG) was detected in 72.5% (87) of cases with IBS, whereas this ratio was 36.2% (50) in patients without (p<0.001). Similarly, although the prevalence of hemorrhoid was 33.3% (40) in the IBS cases, it was 15.2% (21) in the other group (p<0.001). Beside that, urolithiasis was detected in 17.5% (21) of the cases with IBS and in 11.5% (16) of the cases without (p<0.05). Additionally, the prevalence of depression was higher in the IBS group (p<0.001). Conclusion: Relationships between IBS and CG, hemorrhoid, urolithiasis, and depression are significant, and IBS is a cascade of many physiologic events, being initiated with psychological disturbances-like many stresses and eventually terminating with gut dysfunction. Keeping in mind these associations will be helpful for physicians during prevention, treatment, and follow up of these patients.Öğe THE PROTECTIVE EFFECTS OF PEPTIDE YY AND GHRELIN IN ACUTE BILIARY PANCREATITIS(Carbone Editore, 2014) Aydogan, Akin; Akkucuk, Seckin; Ozkan, Orhan Veli; Aydin, Mehmet; Motor, Sedat; Ugur, Mustafa; Oruc, CemAim: Glzrelin and peptide YY are gut hormones that have an anti-inflammatory effect by inhibiting proinflammatory cytokines. We aimed to determine the anti-inflammatory and protective effects of ghrelin and Peptide YY. Methods: The study group included 28 patients with acute biliary pancreatitis and 38 controls. Ghrelin, peptide YY, IL-6, TNF-alpha, amylase, lipase, glucose, alanine aminotransferase, aspartate aminotransferase, leucocyte count, and hematocrit were measured three times in each patient and once in the control group. Results: Ghrelin levels tended to increase as treatment continued, but still were below the levels in the control group. On the other hand, peptide YY levels in all of the patient samples were higher than in the control group (p>0.001). Conclusion: Ghrelin is proposed as a protective hormone for acute pancreatitis. Exogenous ghrelin exhibits protective activity in caerulein-induced pancreatitis. All previous in vivo and in vitro studies have reported that exogenous PYY administration inhibited izzflammation and had protective effects. This study indicates for the first time that endogenous PYY has protective effects on pancreatitis via the inhibition of inflammation, and that these effects are stronger than the effects of ghrelin.Öğe The protective effects of peptide YY and ghrelin in acute biliary pancreatitis(Acta Medica Mediterranea, 2014) Aydogan, Akin; Akkucuk, Seckin; Ozkan, Orhan Veli; Aydin, Mehmet; Motor, Sedat; Ugur, Mustafa; Oruc, CemAim: Ghrelin and peptide YY are gut hormones that have an anti-inflammatory effect by inhibiting proinflammatory cytokines.
