Colonic Lipoma Causing Bowel Intussusception: An Up-to-Date Systematic Review
Lipoma colónico; CirugíaLipoma colònic; CirurgiaColonic lipoma; SurgeryBackground: Colonic lipomas are rare and can sometimes cause intussusception. The aim of this review was to define the presentation and possible management for colocolic intussusception caused by colonic lipomas. Methods: A systematic search for patients with colocolic intussusception caused by colonic lipoma, including all available reports up to 2021. Epidemiological, clinical, laboratory, and instrumental data and details about the treatments performed were gathered. Results: Colocolic intussusception caused by lipoma is more frequent in women (57%), occurring between 40 and 70 years of age. Up to 83% of patients report abdominal pain, followed by constipation (18%), rectal bleeding (16%), and diarrhea (12%), with abdominal tenderness (37%), and distension in 16%, whereas 24% have a negative exploration. CT (72%) and colonoscopy (62%) are more commonly able to diagnose the entity. The most common location of intussusception is the transverse colon (28%). The surgical operation varies according to the site. The average dimensions of the lipoma are 59.81 × 47.84 × 38.9 mm3. Conclusions: A correct preoperative diagnosis of colonic lipoma causing intussusception might not be easy. Despite nonspecific clinical and laboratory presentation, cross-sectional imaging can help differential diagnosis. Surgical treatment depends on the localization.This research received no external funding
765 Is acute response to calcium sensitizers drugs predictive of response to cardiac contractility modulation in NYHA IV patients?
Abstract
A 53-years old man presented to our institution with a diagnosis of decompensated heart failure NYHA Class IV. He had a history of ischaemic heart disease with severe biventricular dysfunction, diabetes, hypertension, dyslipidaemia, advanced chronic kidney disease, previous explanation of dual-chamber implantable electronic device (ICD) due to endocarditis and subsequent implantation of subcutaneous ICD in primary prevention. Home therapy included uptitrated angiotensin-converting enzyme inhibitor, β-blocker, loop-diuretic, spironolactone, acetylsalicylic acid, and oral hypoglycemics. Clinical examination showed signs and symptoms of systemic and pulmonary congestion with pleural effusion and ascites. Echocardiography revealed diffuse left ventricular (LV) hypokinesis with an ejection fraction (EF) of 25%, severe right ventricular dysfunction and increased filling pressures. He was treated with high dose of i.v. diuretics with mild improvement of dyspnoea. However, haemodynamic stability was labile with worsening of symptoms as soon as mild down-titration of iv diuretics was attempted. Levosimendan, a calcium-sensitizer inodilator, indicated for short-term treatment of acutely decompensated severe chronic heart failure (HF), was administered with good clinical response. Thus, we thought that the patient could have benefited from contractility modulation therapy (CCM) which acts on intramyocardial calcium handling. CCM is a novel therapeutic option for patients with classes III–IV HF with EF ≥ 25% to ≤ 45% and narrow QRS complex that acts on intramyocardial calcium-handling. CCM proved effective in alleviating symptoms, improving exercise tolerance and quality of life, and reducing hospitalization rates in HF. It improves myocardial contractility, reverses the foetal myocyte gene program associated with HF and facilitates cardiac reverse remodelling. Therefore, an Optimizer Smart System (Impulse Dynamics) was implanted. Two pacing electrodes were placed on the interventricular septum in apical and mid-septal position, respectively. The leads were connected to a pulse-generator in a right pectoral pocket. In the following days, we observed a progressive improvement in clinical status, with gradual resolution of peripheral oedema, dyspnoea and fatigue and significant weight loss. Six-month echocardiography showed a stable value of EF and significant improvement in stroke volume (35.2 ml from 24.8 ml at baseline). The patient did not undergo further hospitalization for decompensated HF and was in stable ambulatory NYHA Class IV. We believe CCM is an option in patients with advanced HF in which avoiding recurrent hospitalizations, with their overt increase mortality, is often a challenging therapeutic goal. 765 Figur

Noninfectious Granulomatous Lung Disease: Radiological Findings and Differential Diagnosis
Granulomatous lung diseases (GLDs) are a heterogeneous group of pathological entities that can have different clinical presentations and outcomes. Granulomas are histologically defined as focal aggregations of activated macrophages, Langerhans cells, and lymphocytes, and may form in the lungs when the immune system cannot eliminate a foreign antigen and attempts to barricade it. The diagnosis includes clinical evaluation, laboratory testing, and radiological imaging, which especially consists of high-resolution computed tomography. bronchoalveolar lavage, transbronchial needle aspiration or cryobiopsy, positron emission tomography, while genetic evaluation can improve the diagnostic accuracy. Differential diagnosis is challenging due to the numerous different imaging appearances with which GLDs may manifest. Indeed, GLDs include both infectious and noninfectious, and necrotizing and non-necrotizing granulomatous diseases and the imaging appearance of some GLDs may mimic malignancy, leading to confirmatory biopsy. The purposes of our review are to report the different noninfectious granulomatous entities and to show their various imaging features to help radiologists recognize them properly and make an accurate differential diagnosis

How Immunotherapy Has Changed the Continuum of Care in Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is one of the leading causes of death worldwide. The use of local treatment, such as surgical resection, liver transplant, and local ablation, has improved the survival of patients with HCC detected at an early stage. Until recently, the treatment of patients with metastatic disease was limited to the use of the multikinase inhibitor (MKI) sorafenib with a marginal effect on survival outcome. New target approaches, such as the oral MKI lenvatinib in first-line treatment and regorafenib, ramucirumab, and cabozantinib in later lines of therapy, have demonstrated efficacy in patients with preserved liver function (Child–Pugh class A) and good performance status. On the other hand, the implementation of immune checkpoint inhibitors directed against PD-1 (nivolumab and pembrolizumab), PD-L1 (atezolizumab), and anti-CTLA4 (ipilimumab) in the management of advanced HCC has strongly changed the continuum of care of HCC. Future research should include the evaluation of molecular biomarkers that can help patient selection and provide new insight on potential combined approaches. In this review, we provide an overview of the clinical evidence of the use of immune checkpoint inhibitors in HCC, and discuss how immunotherapy has been implemented into the continuum of HCC care
