Today, an ever-increasing number of diseases requiring a surgical solution are treated by means of minimally invasive procedures [1]. When possible, these procedures are suggested instead of traditional approaches because they decrease both the surgical risk and postsurgery hospitalization. The growing technological advances in terms of imaging techniques (i.e., visualization of organs and tissues) and handling of the minimally invasive instruments (e.g., endoscopes) play a key role in improving the qualitative aspects of the interventions [2].

BACKGROUND: Oxidized regenerated cellulose (ORC) is a bioabsorbable surgical hemostatic. We present the first prospective case series of circumscribed mass occurrence after using ORC in laparoscopic cholecystectomy. METHODS: Tabotamp (Ethicon, Inc., Somerville, NJ) in the form of tightly woven knitted patches was used to achieve hemostasis in 83 patients submitted to LC. RESULTS: A subhepatic mass was detected in five patients and radiologic characteristics were described. Abdominal contrast enhanced CT showed a heterogeneous soft-tissue mass.

Purpose: To analyse the classification performances of a decision tree method applied to predictor variables in survival outcome in patients with locally advanced rectal cancer (LARC). The aim was to offer a critical analysis to better apply tree-based approach in clinical practice and improve its interpretation. Materials and methods: Data concerning patients with histological proven LARC between 2007 and 2014 were reviewed. All patients were treated with trimodality approach with a curative intent. The Kaplan–Meier method was used to estimate overall survival (OS).

Background. The SARS-CoV-2 pandemic, with over 430,000 cases and more than 19,000 deaths globally, forced healthcare systems to reorganise surgical activities. Methods. The paper is intended to be a reference for medical, nursing, social workers and ancillary hospital staff to implement the national and regional governments’ decisions and focus on the Infection Prevention and Control. Results. From the gathered informations, suggestions are given to check carefully workflow and optimize the pre, intra and postoperative elective and emergency surgical activities Results.

Goal: The aim of our prospective study was to analyze the results of endoscopic stenting to treat obstruction due to colorectal cancer and complications after colorectal resection for cancer.
Background: Endoscopic stenting for obstructing colorectal cancer has become a common place in clinical practice. However, there is a 2% to 5% risk of bowel perforation, and a percentage of technical failure of 2% to 10%.

Background: Laparoscopy has now been implemented as a standard of care for elective colonic resection around the world. During the adoption period, studies showed that conversion may be detrimental to patients, with poorer outcomes than both laparoscopic completed or planned open surgery. The primary aim of this study was to determine whether laparoscopic conversion was associated with a higher major complication rate than planned open surgery in contemporary, international practice. Methods: Combined analysis of the European Society of Coloproctology 2017 and 2015 audits.

There is little evidence to support choice of technique and configuration for stapled anastomoses after right hemicolectomy and ileocaecal resection. This study aimed to determine the relationship between stapling technique and anastomotic failure.

Background. This is a multicenter study performed in two Ita- lian tertiary care centers: General Emergency Surgery Unit at St. Orsola University Teaching Hospital - Bologna and Department of Surgical Sciences at Umberto I University Teaching Hospital - Ro- me. The aim was to compare the results of different approaches among elderly patients with acute bowel ischemia. Methods. Sixty-three patients were divided in two groups: 1) DSgroup- 28 patients treated in Vascular Unit and 2) GEgroup- 35 patients treated in Emergency Surgery Unit. Results.
