Interest of preoperative immunonutrition in liver resection for cancer: study protocol of the PROPILS trial, a multicenter randomized controlled phase IV trial.

Background: Malnutrition is an independent risk factor of postoperative morbidity and mortality and it's observed in 20 to 50% of surgical patients. Preoperative interventions to optimize the nutritional status, reduce postoperative complications and enteral nutrition has proven to be superior to the parenteral one. Moreover, regardless of the nutritional status of the patient, surgery impairs the immunological response, thus increasing the risk of postoperative sepsis.

Single-center multidisciplinary management of patients with colorectal cancer and resectable synchronous liver metastases improves outcomes.

Background: Management of patients with synchronous liver metastasis (SLM) is complex and the surgical decision process should be based on a comprehensive oncological strategy. The aim of the study was to compare outcome of single-center management of patients with colorectal cancer (CRC) and resectable SLM to those of referred patients for liver resection only after removal of their primary tumor (PT).

Methods: Between 2000 and 2007, 47 patients with CRC and SLM underwent resection of both the PT and metastases under our care (unicentric) and 32 were referred after resection of their PT.

Impact of complex Crohn's disease on the outcome of laparoscopic ileocecal resection: a comparative clinical study in 124 patients.

Purpose: This prospective study assessed the feasibility of laparoscopic ileocolonic resection for complex Crohn's disease, i.e., recurrence or complication from abscess and/or fistula, and compared postoperative outcomes in patients with and without complex Crohn's disease.
