Öğe A new technique to simplify the minimally invasive parathyroidectomy: Ultrasound-assisted guided wire localization for solitary parathyroid adenomas(Pakistan Medical Assoc, 2016) Ozkul, Faruk; Arik, Muhammed Kasim; Eroglu, Mustafa; Faydaci, Umut; Toman, Huseyin; Tas, Sukru; Ukinc, KubilayObjective: To investigate the benefits of ultrasound-assisted guided wire localization in MIP for selected cases. Methods: In this prospective, nonrandomised study, we included 36 patients with solitary parathyroid adenomas diagnosed preoperatively by 99m Tc sesta MIBI scintigraphy and/or neck ultrasonography. An ultrasound-guided wire was placed in the solitary parathyroid adenoma preoperatively. MIPs were performed under local anaesthesia plus sedation. After the excision, the parathyroidectomy was confirmed with postoperative ultrasonography. Results: There were 36 patients included in our study. The mean age was 54.89 +/- 11.28 years, and 30 patients were females (83.3%). Preoperative PTH and calcium (Ca) levels were 269.5 pg/mL (83.5-5,000 pg/mL) and 12.2 mg/dL (11.1-20 mg/dL), respectively. Postoperative serum PTH and Ca levels were 42.04 +/- 26.65 pg/mL and 8.95 +/- 0.74 mg/dL, respectively. The mean operation time was 21.69 +/- 6.4 minutes and the average hospitalisation time was 18 hours (range: 10-72 hours). Conclusions: Ultrasound-assisted guided wire localization may be useful in selected MIP cases. The MIP advantages include higher success rates and being easy to learn and practise.Öğe A rare reason of mechanical intestinal obstruction; phytobezoar images for clinicians(TIP ARASTIRMALARI DERNEGI, 2014) Cıkman, Oztekin; Ozkan, Omer Faruk; Adam, Gürhan; Tas, Sukru; Ademoglu, Serkan; Karaayvaz, MuammerMechanical intestinal obstruction is defined as the partial or total blockage of the passage of digested food in gastrointestinal system towards the distal. If intestinal obstruction is not treated properly it can cause high incidences of morbidity and mortality. The most frequent cause is adhesion after surgery but etiological cause changes frequently with age. Known symptoms of intestinal obstructions are nausea, vomiting, abdominal ache and distention in the abdomen. In our study we aimed to present a 70 year old patient with intestinal obstruction due to phytobezoar who developed sepsis, with the help of current literature. © 2014, TIP ARASTIRMALARI DERNEGI.

However, the case series regarding interventional treatment of delayed hemorrhage after PD are limited. In this retrospective study, we aimed to evaluate functional outcomes of interventional treatment of late hemorrhages developing after PD. We retrospectively evaluated 16 patients who received endovascular treatment for delayed arterial hemorrhage after PD procedure. Postsurgical nonhemorrhagic complications, time of hemorrhage, site of hemorrhage, endovascular treatment technique, postprocedural complications, and mortality rates were obtained. Mean duration of delayed hemorrhage after PD was 18 days. Computed tomography angiography images for the hemorrhage period were available for 15 patients. We observed extravasation alone in seven patients and pseudoaneurysm alone in five. Pushable coil was used in 15 patients and covered stent in 1. Two patients died due to hepatic failure, and one patient died because of multiple organ dysfunction syndrome (MODS). Delayed hemorrhage after PD is difficult to identify, but accurate and early diagnosis is of vital importance. To date, most appropriate management of this complication remains unclear. Although endovascular treatment techniques may vary for every patient, it is a reliable and effective method for halting hemorrhage. Therefore, interventional procedures must be primarily considered rather than surgical interventions.Öğe Hypochlorous Acid: A Novel Agent Against Echinococcus granulosus Protoscoleces(Doc Design Informatics Co Ltd, 2023) Gokce, Oruc Numan; Cetin, Kenan; Alkan, Sevil; Tas, Sukru; Dinc, UgurObjective: We aimed to determine the scolicidal effect of hypochlorous acid and its efficiency at different concentrations. Materials and Methods: We tested the effectiveness of hypochlorous acid in -vitro on sterile gauze at different concentrations in test tubes. In addition, we compared its effectiveness with the scolicidal activity of other agents, povidone-iodine 10% and chlorhexidine-gluconate 0.04%. Results: Hypochlorous acid was 100% effective in 5 minutes at 1/1 (200 ppm/mL), 1/10 (20 ppm/mL), and 1/100 (2 ppm/mL) concentrations and in 10 minutes at 1/1000 (0.2 ppm/ mL) concentration. Povidone-iodine 10%, and chlorhexidine-gluconate 0.04% were studied undiluted and were effective at all study times. Hypochlorous acid maintained the same scolicidal activity on gauze at all study times at the described dilutions. Conclusion: Hypochlorous acid is an effective scolicidal agent in 5 minutes at even 1/100 concentrations. In addition, it maintains the same scolicidal activity on gauze used in surgery to wall the surgical site.Öğe In Vitro Effects of Pantoprazole on Contractile Tone and Contraction Frequency of Rat Pyloric Sphincter(Colegio Farmaceuticos Provincia De Buenos Aires, 2017) Tas, Sukru; Ozer, IlterThe goal of this study to evaluate the possible effects of three different doses of pantoprazole exposure on rat pyloric sphincter contractile tone and contraction frequency in an in vitro experimental study. Following a 60 min equilibration period for stabilization, the contractile response to carbachol was obtained by application of a single dose of carbachol. After the contractions plateaued, pantoprazole concentration-response curves for the experimental group (n= 10) were obtained in a cumulative manner for pantoprazole doses of 5 x 10(-6) mol/L, 5 x 10(-6) mol/L and 1.5 x 10(-4) mol/L, with each dose being held for 15 min. In the control group (n= 10), distilled water was added to the organ bath. Mean percentage of changes in contractile tone and contraction frequency were calculated for each 15 min periods. The contractile tone and contraction frequency decreased in all periods in both groups. Neither contraction tone nor contraction frequency mean percentage of change differed among the periods in the control group. In the experimental group, significant inter-period differences were observed for mean change in contraction tone (period 1 vs. 2, p = 0.013) but not for mean change in contraction frequency (all p > 0.05). It was thought that pantoprazole may relax the pyloric ring by decreasing contractile tone in a dose-dependent manner.Öğe Isolated omental panniculitis: two case reports and review of literature(Modestum Ltd, 2017) Tas, Sukru; Cikman, Oztekin; Ozdil, Asli; Akgun, Yilmaz; Karaayvaz, MuammerIsolated omental panniculitis (IOP), a rare form of acute abdominal syndrome, is defined as intraabdominal panniculitis that involves only omentum without extraabdominal fat necrosis, inflammatory bowel disease and pancreatitis. In the search made using PubMed English database, only 4 cases are determined with IOP. IOP is conceptually confused with idiopathic omental infarction (IOI). However, omental infarctions that are rare causes of acute abdominal syndromes were published by Bush for the first time in 1986 and less than 400 cases were reported. In this article we aimed to publish 2 IOP patients who applied with acute abdominal manifestation and were treated with laparoscopic omental resection to discuss the other 4 IOP cases comparing with IOP together with literature.Öğe L-carnitine has a protective effect on the colonic mucosa during abdominopelvic radiotherapy in rats(Acta Cirurgica Brasileira, 2016) Tas, Sukru; Ozkan, Omer Faruk; Cikman, Oztekin; Kiraz, Asli; Akgun, Yilmaz; Karaayvaz, MuammerPURPOSE: To evaluate histopathologically the radioprotective effect of L-carnitine on the colonic mucosa in rats undergoing abdominopelvic irradiation. METHODS: Thirty-two rats were randomly assigned to four experimental groups: intraperitoneal administration of normal saline (group 1) or L-carnitine (300 mL/kg; group 2), followed in groups 3 and 4, respectively, by one dose of abdominopelvic radiation (20 Gy) 30 min later. Rats were sacrificed 5 days after radiation, and their descending colons were resected for histopathological evaluation of the presence and severity of damage. RESULTS: Average damage scores did not differ significantly between groups 1 and 2 (0.13 +/- 0.35 and 0.25 +/- 0.46, respectively); the group 3 score was highest (10.25 +/- 0.71), and the group 4 score (3.63 +/- 1.41) was significantly lower than that of group 3 (both p = 0.0001). Pre-radiation L-carnitine administration significantly reduced mucosal thinning, crypt distortion, reactive atypia, inflammation, cryptitis, and reactive lymph-node hyperplasia (all p < 0.01). CONCLUSIONS: L-carnitine had a radioprotective effect on rat colonic mucosa. L-carnitine use should be explored for patients with gastrointestinal cancer, who have reduced serum L-carnitine levels.Öğe Laparoscopic Repair of Combined Right Diaphragm and Liver Injuries with a Sharp Object: A Case Report(Hindawi Ltd, 2013) Arik, M. Kasim; Tas, Sukru; Ozkul, Faruk; Sahin, Hasan; Karatag, Ozan; Karaayvaz, MuammerIntroduction. Diaphragm injuries develop following penetrating or blunt traumas. The purpose of the case report is to present a 28 year old male patient with stable hemodynamic findings treated with laparoscopic approach following a liver injury combined with a right diaphragm injury caused by a sharp penetrating object. Case. 4 cm long transverse laceration was observed near the middle axillary line in the 6th right intercostal space in the examination performed on a 28 year old male patient who applied to the emergency service due to sharp penetrating object injury. Respiratory sounds were decreased in the right side and the examination revealed sensitivity in the abdomen. Elevation in the right diaphragmand hemopneumothorax was monitored in chest X-ray and computerized tomography. Closed subaqueous thorax drain was placed and the patient was taken to the surgery with a right diaphragm injury prediagnosis. Laparoscopic exploration was performed to the patient with stable hemodynamic findings by entering through 10 mm port above the abdomen. 6 cm long injury at the right side of diaphragm and approximately 2 cm deep at the deepest point and 5 cm long linear laceration was observed in the 7th segment of the liver. The diaphragm was repaired laparoscopically with sutures that do not melt on their own. Tampon was applied to the laceration in the liver and bleeding control was performed with suture. Patient was discharged on the 3rd day because he had no problems during postoperative follow-ups. Result. No noticed right side diaphragm rupture and possible concomitant visceral organ injuries following a penetrant injury that can cause significant mortality and morbidity should be definitely kept in mind. The detection of right side diaphragm and liver injury is vital with high mortality in case of delayed diagnosis, and direct radiography and computerized tomography are helpful in the diagnosis. Surgical treatment with laparoscopic approach is a method that leads to less hospitalization duration and less pain in cases that are hemodynamically stable.Öğe MANAGEMENT OF FLAP DEHISCENCE AFTER LIMBERG PROCEDURE FOR RECURRENT PILONIDAL DISEASE BY NEGATIVE PRESSURE WOUND THERAPY (NPWT)(Colegio Brasileiro Cirurgia Digestiva-Cbcd, 2017) Tas, Sukru; Ozkan, Omer Faruk; Ocakli, Muzaffer Muazzez; Arslan, Emrah; Kiraz, Asli; Karaayvaz, Muammer[Anstract Not Available]Öğe Perianal Giant Condyloma Acuminatum-Buschke-Lowenstein Tumor: A Case Report(Hindawi Ltd, 2012) Tas, Sukru; Arik, Muhammet Kasim; Ozkul, Faruk; Cikman, Oztekin; Akgun, YilmazCondyloma acuminatum caused by Human Papillomavirus is the most commonly occurring sexually transmitted infection in the anogenital region. Buschke-Lowenstein tumor (BLT) known also as giant condyloma acuminatum is a rare disease. The disease, for which the most important treatment method is the surgical excision, differs from normal condyloma acuminatum cases with its high degree of malignancy. The purpose of this paper is to present the case that reached huge dimensions in the perianal region and that was treated with wide resection in the literature.Öğe Relationship between serum fibronectin levels and carnitine administration: an experimental study in rats(Wiley, 2014) Ozkan, Omer F.; Komurcu, Erkam; Arik, Muhammet K.; Kemik, Ahu S.; Tas, Sukru; Nusran, GurdalWe aimed to investigate the relationship between dorsal flap viability and serum fibronectin levels in carnitine-administered rats. A total of 24 rats were equally divided into three groups and operated on. Group 1 (sham group n = 8): following surgery, no agent was given. Group 2 (control group, n = 8): following surgery, sterile saline solution at 09% with a dose of 100 mg/kg per day for 7 days was administered intraperitoneally. Group 3 (study group, n = 8): following surgery, carnitine with a dose of 100 mg/kg per day for 7 days was administered intraperitoneally. The flap model used was a 10 x 3 cm dorsal flap extending from the tip of the scapula to the hip joint. This was elevated, and then sutured back to its original site. At the end of postoperative day 8, the animals were anaesthetised and blood samples were collected from intracardiac space. Then, the animals were euthanised. Flap viability was then evaluated measuring the surviving area, using a transparent graph paper. Finally, excised tissue was examined histopathologically. The percentages of viable areas in groups 1, 2 and 3 were 6468 +/- 337%, 6735 +/- 582% and 7515 +/- 356%, respectively. The mean value of fibronectin levels in groups 1, 2 and 3 were 223 +/- 35, 231 +/- 35 and 31 +/- 68 mg/dl, respectively. The results of this study demonstrated that 100 mg/kg carnitine administration led to an increase in flap viability, and increased serum fibronectin levels might have a role in this process.Öğe The effect of amifostine on bacterial translocation after radiation induced acute enteritis(Acta Cirurgica Brasileira, 2016) Tas, Sukru; Ozkul, Faruk; Arik, Muhammet Kasim; Kiraz, Asli; Vural, AhmetPURPOSE: To investigate the effects of amifostine on bacterial translocation and overgrowth in colonic flora after acute radiation enteritis in a rat model. METHODS: Thirty-two female Wistar albino rats were divided into four groups: Group-1 (n = 8): only normal saline was administered intraperitoneally. Group-2 (n = 8): first serum saline was administered intraperitoneally and 30 minutes later 20 Gy radiation was applied to abdominopelvic region. Group-3 (n = 8): only amifostine 200 ml/kg was administered intraperitoneally and radiation was not applied. Group-4 (n = 8): first amifostine 200 ml/kg was administered intraperitoneally and 30 minutes later 20 Gy radiation was applied to abdominopelvic region. On the 5th day after radiation, samples of mesenteric lymph tissues and cecal contents were taken by laparotomy for microbiological culture. RESULTS: Intraperitoneal amifostine administration significantly decreased the bacterial overgrowth related to radiation in colon but did not significantly decrease the bacterial translocation. CONCLUSION: Although not providing a full protection on the damaged mucosal barrier, amifostine significantly decreased the bacterial overgrowth in the cecal content after high dose radiation. There is a need to find out appropriate amifostine dose under different radiation applications avoiding bacterial translocation in gastrointestinal system.Öğe Wernicke's Encephalopathy Following Gastrointestinal Surgery: MRI and DWI Findings(Turkish Neurological Soc, 2014) Kizildag, Betul; Canan, Arzu; Sen, Halil Murat; Tas, Sukru; Cikman, Oztekin; Dagistan, EmineWernicke's encephalopathy (WE) is a neurologic disorder resulting from thiamine (vitamin B1) deficiency characterised by the ocular signs, altered consciousness and ataxia. It is usually associated with chronic alcohol abuse. Recently, it emerged as a complication following bariatric surgery. The classical clinical triad occurs in a small group of patients, and early replacement of thiamine is an important prognostic factor. Hence, magnetic resonance imaging (MRI) is useful to support the diagnosis. In this case, we report MRI and diffusion weighted imaging findings of WE in a patient without history of alcoholism after gastrointestinal surgery.
