Background The aim of this study was to evaluate the diagnosis and management of postoperative bile leaks, reporting typical diagnostic findings and available percutaneous techniques in association with other diagnostic and management methods. Methods Thirty-six patients (28 male) were treated for postoperative bile leaks. A biliary leak was clinically suspected in case of persistent leakage of bilious material from a surgical drain, or in the presence of non-specific symptoms such as abdominal pain, fever and anorexia, with or without laboratory alteration of liver enzymes. Radiological confirmation was mainly based on noninvasive methods such as ultrasound, computed tomography, and magnetic resonance cholangiopancreatography. We assessed each treatment by evaluating multiple factors, including technical success (TS) and clinical effectiveness (CE), defined as primary or secondary. We also evaluated overall CE (OCE), defined as leak control with either single or multiple procedures. Results TS and OCE were achieved in all patients (36/36; 100%) with a grade A or B biliary leak. No grade C was observed. There were no major complications. Minor complications were observed in 7/36 (19.4%) patients. No procedure-related deaths occurred. Conclusions In our study, considering all percutaneous techniques, leak healing was achieved in all the patients with a grade A or B biliary leak. These procedures provide a less invasive approach and are increasingly recognized as having a significant role in the management of complications and should be considered as an integral component in the postoperative management of these patients.

Background Endovascular therapy, including aspiration thrombectomy and local thrombolytic therapy, often associated with angioplasty and stent placement, has been described in the literature. The purpose of this study was to review case series of patients with acute mesenteric ischemia treated with endovascular therapy and evaluate their outcomes. Methods An online review using PubMed was carried out to identify all English articles about this topic in the time interval from 2005 to 2016. The following variables were extracted: number of patients, cause of occlusion, symptoms, arteries involved, number of sessions of treatment, technical success, clinical success, recurrence rate, complications, mortality rate, number of patients who underwent diagnostic laparoscopy or surgical resection of ischemic bowel. Results Eighteen papers met the inclusion criteria and were included. Among the patients with arterial mesenteric ischemia treated with endovascular approach, the technical success rate was high (up to 100%) and data regarding clinical success are encouraging, even though they are few and heterogeneous. Technical success rate and clinical success of patients with acute venous mesenteric ischemia approached with endovascular treatment was 74-100% and 87.5-100% respectively. Conclusions Current advances in endovascular therapies have made these treatments feasible for mesenteric ischemia.
