Association of indirect measurement of cell function by bioimpedance analysis with complications in oncologic hepatic surgery.

Background: Bioelectric impedance vector analysis (BIVA) is a reliable tool to assess body composition. The aim was to study the association of BIVA-derived phase angle (PA) and standardized PA (SPA) values and the occurrence of surgery-related morbidity.

Methods: Patients undergoing hepatectomy for cancer in two Italian centers were prospectively enrolled.

Transversal hepatectomies: Classification and intention-to-treat validation of new parenchyma-sparing procedures for deep-located hepatic tumors.

Background: Deep-located liver tumors involving hepatic veins at the caval confluence or main Glissonean pedicles generally require a major hepatectomy. An intraoperative ultrasound guidance policy opened a possibility to opt for parenchyma-sparing procedures as alternatives to major hepatectomy, called transversal hepatectomies. We ought to standardize the procedure and analyze the surgical outcome, oncological suitability, and salvageability.

Very Early Recurrence After Liver Resection for Colorectal Metastases: Incidence, Risk Factors, and Prognostic Impact.

Background: Liver resection for colorectal metastases is affected by a non-negligible recurrence rate. The earlier the recurrence, the worse the prognosis. We analyzed an unexplored topic, i.

Taste perception and expression in stomach of bitter taste receptor tas2r38 in obese and lean subjects.

Differences in taste perception have been related to eating behavior, nutritional status, and diseases. Recently, taste receptors have been identified in several extra-oral tissues, such as the gastrointestinal tract, where they seem to influence processes like digestion, sense of satiety as well as energy balance and intraluminal changes occurring in obesity. Our study aims to analyze differences in taste perception among 42 obese patients (OB) and 41 normal-weight subjects (LEAN).

Hepatic and Extrahepatic Colorectal Metastases Have Discordant Responses to Systemic Therapy. Pathology Data from Patients Undergoing Simultaneous Resection of Multiple Tumor Sites.

Background: Systemic therapy is the standard treatment for patients with hepatic and extrahepatic colorectal metastases. It is assumed to have the same effectiveness on all disease foci, independent of the involved organ. The present study aims to compare the response rates of hepatic and extrahepatic metastases to systemic therapy.

Non-operative management of rectal cancer: future perspectives turning into reality?

The management of rectal cancer has considerably changed over the last decades and complete response to neoadjuvant chemoradiotherapy is becoming a common clinical entity. There is still no consensus on the definition of complete response to neoadjuvant treatment prior to surgery. Treatment programs are mostly heterogeneous and non-randomized.
