This work analyzes the controversial problems of lymphology, which require the scientific substantiation. Authors express their opinion on the functional anatomy of the lymphatic system, based on their own research and the literature data. The issues of lymphatic drainage from the spleen, bones, muscles, ligaments and fascia are discussed. The data on the diameter of the lymphatic vessels and its variability are presented. The significant attention is given to the changes of the lymphatic system structures during dehydration and rehydration. The role of lymphatic capillaries in the inflammatory processes is emphasized. The contradictions in the description of lymphatic postcapillaries are noted.

Introduction And Importance: Oral Lymphangioma is a rare benign tumor that arises from the lymphatic vessels in oral cavity. It is a development defect in the lymphatic system, which is less common than other types of vascular anomalies, and the incidence in the general population is very low, especially in the oral cavity. It typically presents as soft, painless swelling, often found on the tongue, lips or floor or the mouth.

The aim of this study was to describe the features of myocardial lymph flow using a new combined method of visualization of the lymphatic system. The study was performed on pig hearts harvested from a local slaughterhouse. The original dye, consisting of lipid-soluble chlorophyll and lipiodol, was injected stepwise into the lymphatic vessels.

Since the adoption of neoadjuvant chemoradiation and total mesorectal excision as the standard in rectal cancer care, there has been marked improvement in the local recurrence rates. In this context, restaging magnetic resonance imaging (MRI) plays a key role in the assessment of tumor response, occasionally enabling organ-sparing approaches. However, the role of restaging MRI in evaluating lateral lymph nodes remains limited.

Metastatic lateral pelvic lymph node (LPN) in rectal cancer has a significant clinical impact on the prognosis and treatment strategies. But there are still debates regarding prediction of lateral pelvic lymph node metastasis and its oncological impact. This review explores the evidence for predicting lateral pelvic lymph node metastasis and survival in locally advanced rectal cancer.

Lateral lymph node dissection (LLND) is getting global attention as an a surgical option to reduce local recurrence in locally advanced rectal cancer. As the transanal total mesorectal excision (TaTME) is gaining popularity worldwide, a novel LLND approach was established adopting a two-team approach that combines the transabdominal and transanal approaches using the TaTME technique. This narrative review describes the advantages, anatomical landmarks, surgical techniques, and pitfalls of transanal LLND (TaLLND).
