Immediate ileal ureter replacement for ureteral avulsion during ureterescopy.

Introduction: Complete ureteral avulsion represents a rare and fearsome complication of ureteroscopy, reported in less than 1% of cases. In literature there are few reports and different options are presented for its treatment. We present a case of a ureteral avulsion managed with ileal ureter replacement.

Bail-out intracranial stenting with Solitaire AB device after unsuccessful thrombectomy in acute ischemic stroke of anterior circulation.

Background: Recent trials established the efficacy of mechanical stent-retriever thrombectomy for treatment of stroke patients with large vessel occlusion (LVO) in the anterior circulation. However, stent-retriever thrombectomy may not accomplish successful recanalization in all patients. The aim of this study is to report the role of bail-out permanent stenting after failure of mechanical thrombectomy.

Usefulness of contrast-enhanced ultrasound (CEUS) in Inflammatory Bowel Disease (IBD).

Intestinal ultrasonography has emerged as a cheap, non-invasive and readily accessible modality for the assessment of a number of gastroenterological diseases. Over the last decade, particularly due to the widespread use of biological agents in Inflammatory Bowel Disease (IBD), guidelines regarding management and follow-up advise more regular disease assessment and surveillance in order to guide treatment adjustments, and provide more personalised care. Given the young age of the majority of patients with IBD the availability of an alternative modality to harmful radiation or the risks of endoscopy for this indication offers an appealing advantage.

Uniportal video-assisted thoracic surgery for major lung resections: pitfalls, tips and tricks.

Nearly six years since inception, uniportal video-assisted thoracic surgery (VATS) has become a growing part of major lung resections and has revolutionized the way thoracic surgeons treat pulmonary lesions. This technique is being touted for various benefits. It ensures direct visualization together with a better exposure of the lung and allows the chance of a digital palpation of the lesion through a small incision.

Surgical anatomy of gastric lymphatic drainage.

The lymphatic system of the stomach is a multidirectional and complex network composed of lymphatic nodes and vessels. Lymph node metastasis is the most important prognostic factor in curable gastric cancer and lymph node dissection is one of the main areas of surgical research in gastric cancer. Therefore the anatomical classification and embryological development of the gastric lymphatic system have been well described in the literature.

Results: Mean age was 66.

Combined locoregional treatment of patients with hepatocellular carcinoma: State of the art.

In recent years, a combination of intervention therapies has been widely applied in the treatment of hepatocellular carcinoma (HCC). One such combined strategy is based on the combination of the percutaneous approach, such as radiofrequency ablation (RFA), and the intra-arterial locoregional approach, such as trans-arterial chemoembolization (TACE). Several types of evidence have supported the feasibility and benefit of combined therapy, despite some studies reporting conflicting results and outcomes.

Neo-adjuvant chemo(radio)therapy in gastric cancer: Current status and future perspectives.

In the last 20 years, several clinical trials on neoadjuvant chemotherapy and chemo-radiotherapy as a therapeutic approach for locally advanced gastric cancer have been performed. Even if more data are necessary to define the roles of these approaches, the results of preoperative treatments in the combined treatment of gastric adenocarcinoma are encouraging because this approach has led to a higher rate of curative surgical resection. Owing to the results of most recent randomized phase III studies, neoadjuvant chemotherapy for locally advanced resectable gastric cancer has satisfied the determination of level I evidence.

Bacterial flora as a cause or treatment of chronic diarrhea.

Intestinal microflora can be considered an organ of the body. It has several functions in the human gut, mostly metabolic and immunologic, and constantly interacts with the intestinal mucosa in a delicate equilibrium. Chronic diarrhea is associated with an alteration of gut microbiota when a pathogen invades the gut and also in several conditions associated with intestinal mucosal damage or bowel dysfunction, as in inflammatory bowel disease, irritable bowel syndrome, or small bowel bacterial overgrowth.

Multi-detector CT angiographic imaging in the follow-up of patients after endovascular abdominal aortic aneurysm repair (EVAR).

Background: Multidetector computed tomography (MDCT) angiography represents the standard of reference in the follow-up of patients after endovascular abdominal aortic aneurysm repair (EVAR), being effective in the detection of the full spectrum of possible complications on both axial and 3D images.

Methods: The purpose of this article is to review the normal CT angiography findings of the different types of stent-grafts and to describe the radiological findings of early and late complications after EVAR on axial and reconstructed images. A selection of cases of post-EVAR MDCT angiography is presented to learn the techniques most commonly used for endovascular treatment, the correct CT scanning technique to acquire the data, the full gamut of possible procedure-related complications and how these complications usually appear on CT images.

Cutting-balloon angioplasty of resistant ureteral stenosis as bridge to stent insertion.

Ureteral stenting is a routine, minimally invasive procedure performed for relief of benign or malignant obstruction. In case of ureteral stenosis, to allow a correct insertion of the stent, a predilatation of the ureter stenosis with a conventional balloon catheter can be necessary. In exceptional cases, it can be difficult to advance an 7-8 Fr JJ-catheter over a tight resistant ureter stenosis following unsuccessful high-pressure balloon dilatation.
