The Lymphatic System
Lymphedema is characterized by an abnormal accumulation of protein-rich fluid within the interstitium, resulting in swelling of the affected area. It can manifest as primary lymphedema when it results from a structural or developmental defect in the lymphatic system, or as secondary lymphedema, which is due to iatrogenic causes.

NAFLD and Bariatric/Metabolic Surgery as Its Treatment Option
The prevalence of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) has considerably increased over the last years. NAFLD is currently the most common cause of chronic liver disease in the developing world. The diagnosis of NAFLD/NASH is often incidental, as the early-stage of disease is frequently free of symptoms. Most patients recognized with NAFLD have severe obesity and other obesity-related disease such as type 2 diabetes mellitus (T2DM), insulin-resistance, dyslipidemia and hypertension. The only proven method for NAFLD improvement and resolution is weight loss. Bariatric surgery leads to significant and long-term weight loss as well as improvement of coexisting diseases.

Morphological Variation of Infrarenal Abdominal Aortic Aneurysm Neck
Hostile aortic neck characteristics, such as short length and large diameter, have been associated with type Ia endoleaks and reintervention after endovascular aneurysm repair (EVAR). However, such characteristics partially describe the complex aortic neck morphology. The statistical shape model (SSM) of the infrarenal neck is an objective model that provides a quantitative description of the 3D neck morphology of an individual patient.

Augmented Reality in Minimally Invasive Surgery Procedures
Augmented reality (AR) technology is gaining increasing interest in the development of minimally invasive surgery (MIS) procedures. The main application areas can be divided into three main groups: Navigation, education and training, and user-environment interfaces. Although AR-guided navigation systems do not yet offer a precision advantage, benefits include improved ergonomics and visualization, as well as reduced surgical time and blood loss. Benefits are also seen in improved education and training conditions and improved user environment interfaces, which may indirectly influence MIS procedures. Controlled studies with large case numbers and standardized outcome parameters and reporting are lacking to confirm the added value for clinical use.

Known Factors of Acute Pancreatitis
Pancreatitis is regarded by clinicians as one of the most complicated and clinically challenging of all disorders affecting the abdomen. It is classified on the basis of clinical, morphological, and histological criteria. Causes of acute pancreatitis can easily be identified in 75–85% of patients. The main causes of acute, recurrent acute, and chronic pancreatitis are gallstone migration and alcohol abuse. Other causes are uncommon, controversial, or unexplained. For instance, cofactors of all forms of pancreatitis are pancreas divisum and hypertriglyceridemia. Another factor that should be considered is a complication of endoscopic retrograde cholangiopancreatography: post-endoscopic retrograde cholangiopancreatography acute pancreatitis.

Orbital Metastases
Orbital metastases may significantly worsen the functional status of oncological patients, leading to debilitating visual impairments. Surgical resection, orbital exenteration, and complementary therapies may result in heterogeneous clinical outcomes. Most orbital metastases occur at later stages after primary tumors, frequently showing diffuse location within the orbit and rarely invading intracranial structures. Biopsy-only techniques were more frequently preferred in view of the less invasive approaches, but surgical resection and orbital radiotherapy were related to improved clinical outcomes. Although patients with primary breast cancer and patients undergoing resection showed superior prognoses, overall survival rates were generally poor, suggesting the need to better understand orbital metastases’ microenvironments for devising optimal systemic treatment strategies.

Lung Segmentectomy in Non-Small Cell Lung Cancer Surgery
Current guidelines recommend surgery for early-stage non-small cell lung cancer (NSCLC). The standard treatment for patients with cT1N0 NSCLC has been lobectomy with lymph-node dissection, with sublobar resection used only in patients with inadequate cardio-respiratory reserve, with poor performance status, or who are elderly. The results of two randomized controlled trial recently had changed the point of view, giving a new important role to the sublobar resections.

Textured Surface Implants and BIA-ALCL
Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a variant of anaplastic large cell lymphoma (ALCL) associated with textured-surface silicone breast implants. Since first being described in 1997, over 1100 cases have been reported worldwide. A causal relationship between BIA-ALCL and textured implants has been established in epidemiological studies.

Multi-Disciplinary Approach to Colorectal Liver Metastasis
Colorectal cancer (CRC) is the second most common cause of cancer-related mortality in the United States. Despite best efforts, 5-year survival for unresectable metastatic CRC is only about 20%. CRC is a heterogeneous disease and the underlying genetic differences inform behavior, treatment strategy, and prognosis. Given the limitations of cytotoxic chemotherapy and the growing role of molecular profiling, research has focused on identifying and developing targeted therapies.

Treatment of the Lips Using a CO2 Laser
A number of studies have recently demonstrated the effectiveness of CO2 laser irradiation for the repair and regeneration of scar tissue from injuries or surgical wounds. However, such studies of the oral mucosa are highly limited. Previous studies using CO2 laser irradiation have indicated that two factors contribute to esthetic healing, namely, artificial scabs, which are a coagulated and carbonized blood layer formed on the wound surface, and photobiomodulation therapy (PBMT) for suppressing wound scarring and promoting wound healing.
