There are numerous techniques surgeons employ to reduce blood loss during partial hepatectomy. In this literature review, prospective studies from the last 20 years are examined to determine the techniques that are best supported by the literature. Some of the techniques include vascular control, multiple parenchymal transection techniques, various hemostatic agents, low central venous pressure, and hemodilution. The strategies supported most convincingly by the literature include low CVP and total hepatic inflow occlusion.

Angiosarcoma is a rare form of soft tissue sarcoma. Primary small intestinal angiosarcomas are especially uncommon. The clinical presentations of small intestinal angiosarcomas vary but gastrointestinal (GI) bleeding is a frequent finding. We present a case of persistent GI bleeding of unknown etiology culminating in operative exploration demonstrating a primary small intestinal angiosarcoma. A discussion of the diagnosis, pathology, and management of angiosarcoma with a review of the current literature is provided including molecular genetics, difficult cases, and current treatment options.

IMC can be successfully managed endoscopically and thus esophagectomy is avoided in a significant proportion of patients. Endoscopic management may be utilized in the setting of complete resection or radial margin involvement without evidence of submucosal invasion. Close endoscopic follow-up is of paramount importance even in those with negative margins, because recurrent disease may occur following EMR in these patients.

Uncoordinated cell growth is one of the fundamental concepts in carcinogenesis and occurs secondary to dysregulation of the cell cycle. The E2Fs are a large family of transcription factors and are key regulators of the cell cycle. The activation of E2Fs is intimately regulated by retinoblastoma 1 (RB1). The RB pathway has been implicated in almost every human malignancy. Recently there have been exciting developments in the E2F field using animal models to better understand the role of E2Fs in vivo. Genetic mouse models have proven essential in implicating E2Fs in hepatocellular carcinoma (HCC) and liver disease. In this review, the general structure and function of E2Fs as well as the role for E2Fs in the development of HCC and liver disease is evaluated. Specifically, what is known about E2Fs in human disease is explored in depth, and future directions are discussed.
