Extended liver resection has increased during the last decades. However, hepatic hemodynamic changes after resection and the consequent complications like post hepatectomy liver failure are still a challenging issue. The aim of this study was to systematically evaluate the role of stepwise liver resection on hepatic hemodynamic changes. ⋯ Sequential decrease in the RLV decreases the hepatic artery flow /100 g and increases the portal vein flow /100 g and portal vein pressure. As the consequence, the liver goes under more poor-oxygenated blood supply and higher pressure. This may be one of the most important mechanisms of the post hepatectomy liver failure in case of extended liver resection.

The treatment for rectal cancer and benign rectal lesions continues to progress in the arena of minimally invasive surgery. While surgical excision of the primary mass remains essential for eradication of disease, there has been a paradigm shift towards less invasive resection methods. ⋯ Transanal minimally invasive surgery (TAMIS) is a new technology developed to elevate the practice of local excision to state-of-the-art resection. The goal of this article is to evaluate the history, short-term outcomes, and evolution of the TAMIS technique for excision of benign and malignant rectal neoplasia.

Screening or Symptoms? How Do We Detect Colorectal Cancer in an Equal Access Health Care System?
Detection of colorectal cancer ideally occurs at an early stage through proper screening. We sought to establish methods by which colorectal cancers are diagnosed within an equal access military health care population and evaluate the correlation between TNM stage at colorectal cancer diagnosis and diagnostic modality (i.e., symptomatic detection vs screen detection). ⋯ Despite equal access to colorectal cancer screening, diagnosis after development of symptomatic cancer remains more common. Fecal occult blood screen detection is associated with early stage at colorectal cancer diagnosis and is the focus for future initiatives.

Surgeon Volume Correlates with Reduced Mortality and Improved Quality in the Surgical Management of Diverticulitis.
Volume has been shown to be an important determinant of quality and cost outcomes. ⋯ Quality and the use of minimally invasive technique are tightly associated with surgeon volume. Further studies are necessary to validate the direct association of volume with outcomes in surgery for diverticulitis.

A Cohort Study for Derivation and Validation of Early Detection of Pancreatic Fistula After Pancreaticoduodenectomy.
Pancreatic fistula (PF) remains the most important morbidity after pancreaticoduodenectomy (PD). Early drain removal was recently recommended. However, this is not applicable to all cases because the development of severe PF may not be obvious until a later postoperative day (POD). This study aimed to discover ways to detect clinically relevant PF early during the postoperative stage after PD. ⋯ Values of drain amylase and CRP combined were useful to distinguish clinically relevant PF.
