Item Treatment with ultrasound guided percutaneous cholecystostomy in acute cholecystitis: 10-year a single-center experience(2017) Ozyer, Umut; Yildirim, Muge; Yildirim, Utku Mahir; 0000-0002-4300-009X; AAK-9071-2021; AAK-9071-2021Purpose: Evaluating the technical success, clinical outcomes and safety of ultrasound-guided percutaneous cholecystostomy (PC) in patients with acute cholecystitis. Material and Methods: Medical records of patients diagnosed as acute cholecystitis and treated with PC from year 2000 to 2011 were retrospectively examined. ASA scores, leukocyte counts, gall stone presence, bile cultures, additional interventions, interval surgery, procedure-related complications and mortality were reviewed. Results: PC catheters were placed in 127 patients (72 male, 55 female) aged from 31 to 100 years. Technical success of the procedure was 100%. Clinical success was obtained in 86% of the patients. No procedure related mortality or early major complications were observed. Minor complication rate was 7% (9/127) and late major complication rate was 3% (4/127). Thirty day in-hospital mortality rate was 8% (10/127). Six patients died after interval cholecystectomy and 4 patients died before the operation. PC served as a definitive treatment in 74% (17/23) of the patients with acalculous cholecystitis. Fifty-eight percent (31/53) of the patients with acute calculous cholecystitis were treated only with percutaneous cholecystostomy and only 10% (3/31) had recurrent cholecystitis in follow up. Conclusion: PC can be preferred over primary cholecystectomy in acute cholecystitis patients. The procedure has high technical success, high clinical response and low complication rates. It can also serve as a definitive treatment option in patients with high surgical risk.Item Endovascular Management of Surgically Uncontrolled Hemorrhage Following Post-Radical Nephrectomy: A Case Report(2018) Dirim, Ayhan; Ozyer, Umut; 0000-0002-4300-009X; AAK-9071-2021We present an isolated right lumbar arterial hemorrhage following right radical nephrectomy. Surgical re-exploration was unsuccessful therefore active bleeding was diagnosed and treated with endovascular approach.Item Lomber spinal anjiyolipom: a case report(2018) Rahatli, Feride Kural; Ozyer, Umut; 0000-0002-4300-009X; 0000-0002-4226-4034; AAK-9071-2021; AAL-9808-2021Lumbar spinal angiolipomas are rarely seen tumors which present with progressive spinal cord and/or root compression symptoms. Definitive diagnosis with magnetic resonance imaging (MRI) is possible because of their unique signal characteristics. However, probable misdiagnosis is likely due to the infrequency of these tumors. This article reports the case of a 53-year old woman with progressively worsening low back and hip pain in last 6 months. MRI demonstrated a sharply demarcated extradural mass which was hyperintense to cerebrospinal fluid and hypointense to epidural fat on T1-weighted images. The signal was suppressed in fatsaturated images and the mass showed diffuse enhancement after contrast administration.
