The Global Alliance for Infections in Surgery appreciates the great effort of the task force who derived and validated the Sepsis-3 definitions and considers the new definitions an important step forward in the evolution of our understanding of sepsis. Nevertheless, more than a year after their publication, we have a few concerns regarding the use of the Sepsis-3 definitions., Competing Interests: Not applicable.Not applicable.The authors declare that they have no competing interests.Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Background: Serum procalcitonin (PCT) is considered to be a sensitive marker for the early recognition of severe infection. The aim of this study was to review the diagnostic accuracy of serum procalcitonin levels to predict the risk of septic shock and mortality in patients with secondary peritonitis., Methods: We carried out a retrospective review of patients (November 2010 to November 2012) admitted to the surgical intensive care unit (ICU) with secondary peritonitis classified into localised peritonitis (LP) or diffuse peritonitis (DP) groups. Organ dysfunction was assessed with the SOFA score. Demographic data was collected as well as results for neutrophil count, C- reactive protein, blood lactate, and PCT levels. The primary end-point was ICU mortality., Results: From a total of 222 patients, 123 were allocated to the LP group and 99 to the DP group. Severe sepsis was observed in 41.9% of all patients in the DP group. The PCT levels increased significantly in the DP group, with the development of septic shock in 29 patients. Higher PCT levels were associated with an increased risk for septic shock with a cut-off value of 15.3 ng mL⁻¹ and an increased risk for mortality with a cut-off value 19.6 ng mL⁻¹. A total of 59.1% of those who developed septic shock died., Conclusion: An increase in PCT levels is an indirect sign of diffuse secondary peritonitis and this is associated with an increased risk of septic shock. Increased PCT level on admission is associated with an increased risk of mortality in this category of patients.

Background: The control of sepsis is the primary goal of surgical intervention in patients with infected necrosis. Simple surgical approaches that are easy to reproduce may improve outcomes when specialists in endoscopy are not available. The aim of the present study was to describe the experience with a focused open necrosectomy (FON) in patients with infected necrosis., Method: A prospective pilot study conducted to compare a semi-open/closed drainage laparotomy and FON with the assistance of peri-operative ultrasound. The incidence of sepsis, dynamics of C-reactive protein (CRP), intensive care unit (ICU)/hospital stay, complication rate and mortality were compared and analysed., Results: From a total of 58 patients, 36 patients underwent a conventional open necrosectomy and 22 patients underwent FON. The latter method resulted in a faster resolution of sepsis and a significant decrease in mean CRP on Day 3 after FON, P = 0.001. Post-operative bleeding was in 1 versus 7 patients and the incidence of intestinal and pancreatic fistula was 2 versus 8 patients when comparing FON to the conventional approach. The median ICU stay was 11.6 versus 23 days and the hospital stay was significantly shorter, 57 versus 72 days, P = 0.024 when comparing FON versus the conventional group. One patient died in the FON group and seven patients died in the laparotomy group, P = 0.139., Discussion: FON can be an alternative method to conventional open necrosectomy in patients with infected necrosis and unresolved sepsis., (© 2012 International Hepato-Pancreato-Biliary Association.)

B Background: b Minimally invasive approaches considerably changed the surgical management of necrotizing pancreatitis and sepsis. Sepsis-3 definition and C-reactive protein (CRP) level >150 mg/ml, Procalcitonin (PCT) level> 2.0 ng/ml and SOFA score >2 proved the development of sepsis. [Extracted from the article]
