Fluorescence guided surgery in liver tumors: applications and advantages.

The use of fluorescence-guided surgery for benign and malignant hepatobiliary (HPB) neoplasms has significantly increased and improved imaging methods creating new interesting perspectives. A major challenge in HPB surgery is performing radical resection with maximal preservation of the liver parenchyma and obtaining a low rate of complications. Despite the developments, visual inspection, palpation, and intraoperative ultrasound remain the most utilized tools during surgery today.

Conservative treatment of acute appendicitis.

Acute appendicitis has been considered by surgeons a progressive disease leading to perforation for more than 100 years. In the last decades the theories about this concept gained attention, especially in adults. However, appendectomy for acute appendicitis remains the most common urgent/emergent surgical procedure.

The Video-Consulting Emergency protocol: a proposition from the World Society of Emergency Surgery members for the initial management of non-traumatic acute abdomen.

Background: Our aim is to propose the Video-Consulting Emergency (VCE) protocol as a tool to improve the decision-making process between an on-site emergency physician and a remote acute care surgeon using a smartphone, the FaceTime application, and the Acute Abdominal Decision Making (AADM®) model proposed by World Society of Emergency Surgeons members.

Methods: The VCE protocol involves the emergency physician and the on-call emergency surgeon. Both must be provided with a smartphone for 24-hour VC with FaceTime application.

The Congress Impact Factor: A proposal from board members of the World Society of Emergency Surgeons.it (WSES) and Academy of Emergency Medicine and Care (AcEMC).

Many scientific congresses and conferences are held every year around the world. The aim of the World Society of Emergency Surgeons.it (WSES) and Academy of Emergency Medicine and Care (AcEMC) was to develop a simple mathematical parameter as an indicator of academic quality and scientific validity of a congress.

Abdominopelvic trauma: from anatomical to anatomo-physiological classification.

Abdominopelvic trauma has been for decades classified with the AAST-OIS (American Association for the Surgery of Trauma-Organ Injury Scale) classification. It has represented a milestone. At present, the medical evolutions in trauma management allowed an incredible progress in trauma decision-making and treatment.

Open abdomen and entero-atmospheric fistulae: An interim analysis from the International Register of Open Abdomen (IROA).

Introduction: No definitive data describing associations between cases of Open Abdomen (OA) and Entero-atmospheric fistulae (EAF) exist. The World Society of Emergency Surgery (WSES) and the Panamerican Trauma Society (PTS) thus analyzed the International Register of Open Abdomen (IROA) to assess this question.

Material And Methods: A prospective analysis of adult patients enrolled in the IROA.

Knowledge, awareness, and attitude towards infection prevention and management among surgeons: identifying the surgeon champion.

Despite evidence supporting the effectiveness of best practices of infection prevention and management, many surgeons worldwide fail to implement them. Evidence-based practices tend to be underused in routine practice. Surgeons with knowledge in surgical infections should provide feedback to prescribers and integrate best practices among surgeons and implement changes within their team.

2017 WSES guidelines on colon and rectal cancer emergencies: obstruction and perforation.

ᅟ: Obstruction and perforation due to colorectal cancer represent challenging matters in terms of diagnosis, life-saving strategies, obstruction resolution and oncologic challenge. The aims of the current paper are to update the previous WSES guidelines for the management of large bowel perforation and obstructive left colon carcinoma (OLCC) and to develop new guidelines on obstructive right colon carcinoma (ORCC).

Methods: The literature was extensively queried for focused publication until December 2017.

Management of Appendicitis Globally Based on Income of Countries (MAGIC) Study.

Background: Our aim is to compare the management approaches and clinical outcomes of acute appendicitis according to annual Gross National Income per Capita (GNI/Capita) of countries.

Methods: Consecutive patients who were diagnosed to have acute appendicitis from 116 centers of 44 countries were prospectively studied over a 6-month period (April-September 2016). Studied variables included demography, Alvarado score, comorbidities, radiological and surgical management, histopathology, and clinical outcome.

Emergency surgeons' perceptions and attitudes towards antibiotic prescribing and resistance: a worldwide cross-sectional survey.

Background: Antibiotic resistance (AMR) is a growing public health problem worldwide, in part related to inadequate antibiotic use. A better knowledge of physicians' motivations, attitudes and practice about AMR and prescribing should enable the design and implementation of effective antibiotic stewardship programs (ASPs). The objective of the study was to assess attitudes and perceptions concerning AMR and use of antibiotics among surgeons who regularly perform emergency or trauma surgery.

Closed Or Open after Source Control Laparotomy for Severe Complicated Intra-Abdominal Sepsis (the COOL trial): study protocol for a randomized controlled trial.

Background: Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. Principles of treatment include early antibiotic administration and operative source control.

Bologna guidelines for diagnosis and management of adhesive small bowel obstruction (ASBO): 2017 update of the evidence-based guidelines from the world society of emergency surgery ASBO working group.

Background: Adhesive small bowel obstruction (ASBO) is a common surgical emergency, causing high morbidity and even some mortality. The adhesions causing such bowel obstructions are typically the footprints of previous abdominal surgical procedures. The present paper presents a revised version of the Bologna guidelines to evidence-based diagnosis and treatment of ASBO.

Not all diverticulites are colonic: small bowel diverticulitis - A systematic review.

Introduction: Small bowel non-Meckelian diverticulitis (SBNMD) is not so an uncommon cause of admission in departments of emergency surgery. Our aim is to highlight signs and symptoms for early diagnosis and report proper surgical treatments.

Evidence Acquisition: The systematic review protocol was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P).

Prospective Observational Study on acute Appendicitis Worldwide (POSAW).

Background: Acute appendicitis (AA) is the most common surgical disease, and appendectomy is the treatment of choice in the majority of cases. A correct diagnosis is key for decreasing the negative appendectomy rate. The management can become difficult in case of complicated appendicitis.

Getting the invite list right: a discussion of sepsis severity scoring systems in severe complicated intra-abdominal sepsis and randomized trial inclusion criteria.

Background: Severe complicated intra-abdominal sepsis (SCIAS) is a worldwide challenge with increasing incidence. Open abdomen management with enhanced clearance of fluid and biomediators from the peritoneum is a potential therapy requiring prospective evaluation. Given the complexity of powering multi-center trials, it is essential to recruit an inception cohort sick enough to benefit from the intervention; otherwise, no effect of a potentially beneficial therapy may be apparent.

WSES worldwide emergency general surgery formation and evaluation project.

Optimal management of emergency surgical patients represents one of the major health challenges worldwide. Emergency general surgery (EGS) was identified as multidisciplinary surgery performed for traumatic and non-traumatic acute conditions during the same admission in the hospital. EGS represents the easiest viable way to provide affordable and high-quality level of care to emergency surgical and trauma patients.

The open abdomen in trauma and non-trauma patients: WSES guidelines.

Damage control resuscitation may lead to postoperative intra-abdominal hypertension or abdominal compartment syndrome. These conditions may result in a vicious, self-perpetuating cycle leading to severe physiologic derangements and multiorgan failure unless interrupted by abdominal (surgical or other) decompression. Further, in some clinical situations, the abdomen cannot be closed due to the visceral edema, the inability to control the compelling source of infection or the necessity to re-explore (as a "planned second-look" laparotomy) or complete previously initiated damage control procedures or in cases of abdominal wall disruption.

2017 WSES guidelines for the management of iatrogenic colonoscopy perforation.

Iatrogenic colonoscopy perforation (ICP) is a severe complication that can occur during both diagnostic and therapeutic procedures. Although 45-60% of ICPs are diagnosed by the endoscopist while performing the colonoscopy, many ICPs are not immediately recognized but are instead suspected on the basis of clinical signs and symptoms that occur after the endoscopic procedure. There are three main therapeutic options for ICPs: endoscopic repair, conservative therapy, and surgery.

Neoadjuvant chemotherapy in advanced gastric and esophago-gastric cancer. Meta-analysis of randomized trials.

Introduction: Even in after curative surgery and adequate linfoadenectomy the survival of advanced gastric cancer (AGC) remains poor. At present some data have been published on the effects of NACT and perioperative chemotherapy on AGC and Esophago-gastric cancer (EGC) but not definitive ones. The present meta-analysis aims to evaluate the effects of neoadjuvant chemotherapy (NACT) on the AGC and EGC.

Establishing position papers by the WSES.

A position paper (PP) should establish a unified voice in areas where controversy occurs based upon multiple practices and/or therapeutic choices. Typically, a position paper should elucidate the knowledge gap, followed by an evidence-based review of options, leading to an "endorsed position." A position paper should represent more than the opinion or consensus of the authors but should present current opinions and practices supported by the World Society of Emergency Surgery (WSES).

Treatment of Flexible Lesser Toe Deformities.

Lesser toe deformities are among the most common complaints presented to foot and ankle specialists. These deformities present in variable ways, which makes surgical decision making complex. For every type of deformity, there could be a combination of soft tissues and bony procedures, chosen according to the surgeon's preferences.
