    Acute appendicitis, inflammatory appendiceal mass and the risk of a hidden malignant tumor: a systematic review of the literature
    (2017) TEIXEIRA JR., Frederico Jose Ribeiro; COUTO NETTO, Sergio Dias do; AKAISHI, Eduardo Hiroshi; UTIYAMA, Edivaldo Massazo; MENEGOZZO, Carlos Augusto Metidieri; ROCHA, Marcelo Cristiano
    Introduction: Acute appendicitis is significantly common. Despite the increased use of computed tomography, the number of perforated cases has been stable in the past three decades. Between 2% and 6% of patients with acute appendicitis present appendiceal mass, often described as inflammatory phlegmon or abscess. Malignant tumors are confirmed by pathological analysis in 0.9-1.4% of all appendectomies performed to treat acute appendicitis. However, recent series demonstrate an elevated incidence of malignancies, ranging from 5.9 to 12%, in patients with inflammatory appendiceal mass. Methods: The analysis was based on a systematic review of the literature. The articles were searched in PubMed for the period from 1987 to 2016. Articles presenting the incidence of the hidden malignancy among patients with appendiceal inflammatory mass were selected. Variables as age, interval appendectomy rate, the incidence of neoplasm, time to surgery, minimally invasive assessment, histology, right colectomy rate and morbidity were analyzed. Results: A total of 13.244 patients were described as presenting acute appendicitis. Appendiceal tumor is present in approximately 1% of the appendectomies, while the rate of neoplasm varies from 10 to 29% in patients presenting appendiceal inflammatory mass. Interval appendectomies, despite been the minority of the procedures, disregard the higher morbidity associated with right sided colectomies. The review of literature also describes oncologic, histologic and clinical aspects of patients presenting appendiceal neoplasm, describing the most frequent histologic subtypes of this illness. Conclusion: Hidden appendiceal neoplasm in acute appendicitis are rare, fortunately. However, its incidence is much higher in patients presenting appendiceal inflammatory mass. Hence, interval appendectomy should be considered in this subgroup of patients.

    Non-operative management of blunt splenic trauma: evolution, results and controversies
    (2021) MEIRA JÚNIOR, JOSÉ DONIZETI; MENEGOZZO, CARLOS AUGUSTO METIDIERI; ROCHA, MARCELO CRISTIANO; UTIYAMA, EDIVALDO MASSAZO
    ABSTRACT The spleen is one of the most frequently affected organs in blunt abdominal trauma. Since Upadhyaya, the treatment of splenic trauma has undergone important changes. Currently, the consensus is that every splenic trauma presenting with hemodynamic stability should be initially treated nonoperatively, provided that the hospital has adequate structure and the patient does not present other conditions that indicate abdominal exploration. However, several topics regarding the nonoperative management (NOM) of splenic trauma are still controversial. Splenic angioembolization is a very useful tool for NOM, but there is no consensus on its precise indications. There is no definition in the literature as to how NOM should be conducted, neither about the periodicity of hematimetric control, the transfusion threshold that defines NOM failure, when to start venous thromboembolism prophylaxis, the need for control imaging, the duration of bed rest, and when it is safe to discharge the patient. The aim of this review is to make a critical analysis of the most recent literature on this topic, exposing the state of the art in the NOM of splenic trauma.

    Can ultrasound be used as an adjunct for tube thoracostomy? A systematic review of potential application to reduce procedure-related complications
    (2019) MENEGOZZO, Carlos Augusto M.; ARTIFON, Everson L. A.; MEYER-PFLUG, Adriano Ribeiro; ROCHA, Marcelo C.; UTIYAMA, Edivaldo M.
    Background: chest tube insertions are commonly performed in various scenarios. Although frequent, these procedures result in a significant complication rate, especially in the acute care setting. Ultrasonography has been incorporated to interventional procedures aiming to reduce the incidence of complications. However, little is known about the applications of ultrasound in tube thoracostomies. The aim of this systematic review is to present the potential applications of ultrasonography as an adjunct to the procedure. Methods: we searched Medline/Pubmed, EMBASE and Scopus databases. Out of 3012 articles, we selected 19 for further analysis. Thirteen of those were excluded because they did not meet the inclusion criteria. Ultimately, 6 articles were thoroughly evaluated and included in the review. Results: The included articles show that ultrasound can be used to correctly identify a safe insertion site, to accurately find a vulnerable intercostal artery, and is reliable for timely diagnosis of drain malpositioning. Conclusion: this systematic review highlights the potential benefits of incorporating ultrasonography in tube thoracostomies. No randomized clinical trials are available. However, it is reasonable to assume that proper use of ultrasound may reduce procedure-related complications.
