Intra-abdominal infections (IAI) are among the most common global healthcare challenges and they are usually precipitated by disruption to the gastrointestinal (GI) tract. Their successful management typically requires intensive resource utilization, and despite the best therapies, morbidity and mortality remain high. One of the main issues required to appropriately treat IAI that differs from the other etiologies of sepsis is the frequent requirement to provide physical source control. Fortunately, dramatic advances have been made in this aspect of treatment. Historically, source control was left to surgeons only. With new technologies non-surgical less invasive interventional procedures have been introduced. Alternatively, in addition to formal surgery open abdomen techniques have long been proposed as aiding source control in severe intra-abdominal sepsis. It is ironic that while a lack or even delay regarding source control clearly associates with death, it is a concept that remains poorly described. For example, no conclusive definition of source control technique or even adequacy has been universally accepted. Practically, source control involves a complex definition encompassing several factors including the causative event, source of infection bacteria, local bacterial flora, patient condition, and his/her eventual comorbidities. With greater understanding of the systemic pathobiology of sepsis and the profound implications of the human microbiome, adequate source control is no longer only a surgical issue but one that requires a multidisciplinary, multimodality approach. Thus, while any breach in the GI tract must be controlled, source control should also attempt to control the generation and propagation of the systemic biomediators and dysbiotic influences on the microbiome that perpetuate multi-system organ failure and death. Given these increased complexities, the present paper represents the current opinions and recommendations for future research of the World Society of Emergency Surgery, of the Global Alliance for Infections in Surgery of Surgical Infection Society Europe and Surgical Infection Society America regarding the concepts and operational adequacy of source control in intra-abdominal infections., (© 2023.

The objectives of this study are to evaluate the incidence of aortitis on a surgical population, establish any relationship with systemic diseases, verify early and late surgical results and provide clinical and radiological follow-up to determine factors potentially predicting progression of the disease and influencing late outcome. From 2009 to 2017, 237 patients underwent elective operations on the ascending aorta. Segments of the excised tissues were routinely sent for histologic evaluation, providing adequate data in 178 (75%) for a clinical and pathologic correlation. Patients with aortitis (Group 1) (n = 26) were compared with 152 with atherosclerotic or degenerative disease (Group 2). Incidence of aortitis was 15%, being clinically isolated in 73%. In 24 patients (92%), a giant cell aortitis was found. Actuarial survival at 3 years is 88% in Group 1 and 98% in Group 2 and 74% and 98% at 5 years, respectively (P = 0.016). A control angio-computed tomography revealed an increased descending aorta diameter in 2 out of 14 late survivors. A positron emission tomography showed presence of arteritis in other vascular segments in 3 patients. Clinically isolated aortitis is extremely frequent in patients with inflammatory aortic disease. The diagnosis is often difficult and may be supported by routine pathologic evaluation of surgical explants and by multimodality imaging. The latter should be employed to allow adequate patient follow-up and to disclose potential recurrences in untreated aortic segments., (Copyright © 2018 Elsevier Inc. All rights reserved.)
