“…4. The left and middle hepatic veins join to form a single vein before entering the IVC in 60-86 % of people [8,9]. Using TEE, Kirkeby-Garstad et al reported good liver anatomy visualization and an acceptable-quality image of the IVC and the RHV in 95 and 87 % of cases, respectively [10].…”

Purpose Although only limited scientific evidence exists promoting the use of transesophageal echocardiography (TEE) in non cardiac surgery, several recent studies have documented its usefulness during liver surgery. Methods and resultsIn the present case study, through the use of color Doppler TEE, compression of the inferior vena cava and the right hepatic vein was clearly evident, as was their restoration after surgery. Conclusion TEE should be encouraged in patients undergoing liver resection, not only for hemodynamic monitoring, but also for its ability to provide information about the anatomy of the liver, its vessels, and inferior vena cava patency.Keywords Transesophageal echocardiography Á Liver surgery Á Hepatic angioma Á Hemodynamic monitoring Riassunto Il fegato può essere coinvolto da una varietà di patologie, che vanno dalle lesioni benigne come l'angioma epatico, che possono necessitare di essere resecate, all'insufficienza epatica per la quale l'unica terapia possible è il trapianto di fegato. Benchè ci siano solo limitate evidenze scientifiche che supportino l'utilizzo dell'ecografia transesofagea (TEE) nella chirurgia non cardiaca, alcuni studi hanno documentato la sua utilità durante la chirurgia epatica. Nel caso in studio, attraverso l'uso del color Doppler TEE la compressione della vena cava inferiore a della vena epatica destra erano visualizzate così come le loro dimensioni dopo l'intervento chirurgico. Per tale motivo l'utilizzo del TEE dovrebbe essere incoraggiato nei pazienti che vanno incontro a resezione epatica non solo come strumento di valuatzione emodinamica ma anche per la sua abilità di dare informazioni utili sull'anatomia del fegato dei suoi vasi e sulla pervietà della vena cava.

“…The left hepatic vein drains into segments IV(a), II, and III. 19 Thus, the venous drainage is carried out through 3 major veins, but it is important to consider the presence of small veins (mainly in the right lobe of the liver) that also carry out the venous drainage of the inferior vena cava.…”

Many investigations on surgical methods and medical treatment are currently done on pigs. This is possible because the pig is sufficiently close genetically to humans. In recent years, progress in liver surgery has opened new possibilities in surgical treatment of liver diseases. Because the methods are relatively novel, various improvements are still needed, and it is thus helpful to conduct experimental surgeries on pig livers. We reviewed the literature to compare the anatomic and functional features of pig and human livers, information that will be of great importance for improving surgical techniques. During the literature review, we used various sources, such as PubMed, Scopus, and veterinary journals. Our results were summarized in diagrams to facilitate understanding of the vascular structure and biliary systems. We conclude that, although the shapes of the human and pig livers are quite different, the pig liver is divided into the same number of segments as the human liver, which also shows a common structure of the vascular system. Thus, with the anatomic and structural features of the pig liver taken into account, this animal model can be used in experimental hepatic surgery.

“…The liver is located in the upper right quadrant of the abdominal cavity and is the largest organ in the body. The liver has a weight of about 2% or 3% to the total body weight [1]. The liver is an unshaped organ since its shape is mainly determined by the surrounding structures such as the lower ribs and the diaphragm.…”

Segmentation of organs from medical images is an active and interesting area of research. Liver segmentation incurs more challenges and difficulties compared with segmentation of other organs. In this paper we demonstrate a liver segmentation method for computer tomography images. We revisit the distance regularization level set (DRLS) model by deploying new balloon forces. These forces control the direction of the evolution and slow down the evolution process in regions that are associated with weak or without edges. The newly added balloon forces discourage the evolving contour from exceeding the liver boundary or leaking at a region that is associated with a weak edge, or does not have an edge. Our experimental results confirm that the method yields a satisfactory overall segmentation outcome.Comparing with the original DRLS model, our model is proven to be more effective in handling oversegmentation problems.
