Over the last 4 years, major issues still open to debate in the management of AA have been reported concerning the timing of appendectomy, the safety of in-hospital delay, and the indications to interval appendectomy following the resolution of AA with antibiotics [21,22,23,24]. Diagnosis of AA is still challenging and some controversies on its management are still present among different settings and practice patterns worldwide. This new RCT aims to evaluate the role of antibiotics in the resolution of CT-diagnosed uncomplicated AA by comparing antibiotic therapy with placebo to evaluate the role of antibiotic therapy in the resolution of the disease [127]. The theory hypothesizing that perforated AA might be a different disease entity from uncomplicated AA, rather than being the natural evolution of the disease, has some support in the recent meta-analysis by van Dijk et al., demonstrating that delaying appendectomy for up to 24 h after admission does not appear to be a risk factor for complicated AA, postoperative morbidity, or surgical-site infection.

The use of CT in the pediatric population can be reduced by using appropriate clinical and/or staged algorithm based on US/MRI implementation, with a sensitivity up to 98% and a specificity up to 97% and by applying imaging scoring system, such as the Appy-Score for reporting limited right lower quadrant US exams, that performs well for suspected pediatric AA [89,90,91]. Curr Prob Diagnostic Radiol. For high-risk patients, LA has proven to be safe and feasible and was also associated with decreased rates of mortality, postoperative morbidity, and shorter hospitalization. MRI has at least the same sensitivity and specificity as CT and, although higher costs, should be preferred over CT as second-line imaging in children. At a value of 7.5 (a cut of score suggestive of AA in the Eastern population), the RIPASA demonstrated reasonable sensitivity (85.39%), specificity (69.86%), positive predictive value (84.06%), negative predictive value (72.86%), and diagnostic accuracy (80%) in Irish patients with suspected AA and was more accurate than the Alvarado score [34].

In 2018, the same researchers assessed whether the AAST grading system corresponded with AA outcomes in a US pediatric population. Time from admission to theatre did not predict perforation, whereas WBC count at the time of admission was a significant predictor of perforation (OR 1.08; P < 0.001) [134]. This may allow surgeons to provide more conservative management in patients with suspected AA and decrease unnecessary resource utilization [56]. concluded that in children operative findings are more predictive of clinical course than histopathologic results.

En segundo archa, APENDICITIS AGUDA Laparoscopic vs open approach for transverse colon cancer. The preoperative clinical scoring system to distinguish perforation risk with pediatric AA proposed by Bonadio et al., based on the duration of symptoms (> 1 day), fever (> 38.0 C), and WBC absolute count (> 13,000/mm3), resulted in a multivariate ROC curve of 89% for perforation (P < 0.001), and the risk for perforation was additive with each additional predictive variable exceeding its threshold value, linearly increasing from 7% with no variable present to 85% when all 3 variables are present [49].

Cochrane Database of Systematic Reviews. The 5-year follow-up results of the APPAC trial reported that, among patients who were initially treated with antibiotics, the likelihood of late recurrence was 39.1%. Several studies comparing the PAS with the Alvarado score have validated its use in pediatric patients. Current evidence shows that surgical treatment of patients presenting with appendiceal phlegmon or abscess is preferable to NOM with antibiotic oriented treatment in the reduction of the length of hospital stay and need for readmissions when laparoscopic expertise is available [205]. Statement 4.4 In children with acute appendicitis, the single incision/transumbilical extracorporeal laparoscopic-assisted technique is as safe as the laparoscopic three-port technique.

Ocho preguntas clave sobre El diagnóstico y el tratamiento de AA se desarrollaron en Para guiar el análisis de la literatura y su posterior discusión del tema (Tabla 1). Are endoscopic loop ties safe even in complicated acute appendicitis? The authors compared outcomes of percutaneous drainage with antibiotics or antibiotics alone. Appendiceal perforation is associated with increased morbidity and mortality compared with non-perforating AA. The coordinating researcher (S. Di Saverio) invited six experienced surgeons (G. Augustin, A. Birindelli, B. Recommendation 6.2 We suggest the laparoscopic approach as treatment of choice for patients with complicated appendicitis with phlegmon or abscess where advanced laparoscopic expertise is available, with a low threshold for conversion. Overall, the complications reported included SSI, prolonged postoperative ileus, hematoma formation, and small bowel obstruction, but the incidence of any individual complication was not determined [23]. Bonadio W, Shahid S, Vardi L, et al. The implementation of treatment and follow-up protocols based on outpatient antibiotic management and new evidence indicating safety and feasibility of same-day laparoscopic appendectomy for uncomplicated AA may result in optimization of the resource used by reducing inpatient admissions and hospital costs for both NOM and surgical treatment in the future. In the meta-analysis by Kessler et al. 2018;89:224–37. Matthew Fields J, Davis J, Alsup C, et al. World J Surg. 2015;50:1574–8. Blumenfeld YJ, Wong AE, Jafari A, et al. The preoperative distinction between uncomplicated and complicated AA is challenging. The exposure of interest was receipt of systemic extended-spectrum antibiotics (piperacillin ± tazobactam, ticarcillin ± clavulanate, ceftazidime, cefepime, or a carbapenem) on the day of appendectomy or the day after. Gomes) presentó cada una de las declaraciones junto con LoE, GoR y La literatura que respalda cada afirmación. Regarding second-line MRI, pooled sensitivities and specificities were 97.4% and 97.1% [99]. :I ., Wu W-T, Tai F-C, Wang P-C, et al. In the study by Elniel et al., a significant increase in the likelihood of perforated AA occurred after 72 h of symptoms, when compared to 60–72 h. The authors argued that it may be reasonable to prioritize patients approaching 72 h of symptoms for operative management [129]. RCTs and non-randomized comparative studies in which any antibiotic regime was compared to placebo in patients undergoing appendectomy were analyzed. Zani A, Teague WJ, Clarke SA, et al. High-quality RCTs demonstrated shorter hospital stay by 1 day for the LA cohort compared to conservative treatment [207]. Descargar ahora. In children, two recent RCTs showed that SILA is feasible with an acceptable margin of safety, although it does not produce any significant difference in terms of analgesic use and length of hospital stay [145], and it is associated with longer operative times and more severe surgical trauma compared with the three-port technique, as measured by CRP and IL-6 levels [146]. Meta-analysis of in-hospital delay before surgery as a risk factor for complications in patients with acute appendicitis: In-hospital delay before surgery and complications after appendicectomy. Statement 2.1 The antibiotic-first strategy can be considered safe and effective in selected patients with uncomplicated acute appendicitis. The 2018 updated Cochrane review on LA versus OA showed that, except for a higher rate of IAA (intra-abdominal abscess) after LA in adults, laparoscopic demonstrates advantages over OA in pain intensity on day one, SSI, length of hospital stay, and time until return to normal activity [139]. In 2001, a Cochrane meta-analysis supported that broad-spectrum antibiotics given preoperatively are effective in decreasing SSI and abscesses. 2015;212:345.e1–6. Según Ohle et al., El el rendimiento del puntaje depende del valor de corte: se puede aplicar un puntaje de corte clínico de menos de cinco "descartar" apendicitis con una sensibilidad del 99% (IC 95% 97 - 99%) y una especificidad del 43% (36 - 51%), mientras que un puntaje de corte de menos de siete resultados en una sensibilidad de 82% (76 - 86%) y una especificidad del 81% (76–85%), lo que sugiere que no es lo suficientemente preciso para indicar o descartar cirugía. Eficiencia diagnóstica de los sistemas de puntuación clínica y su papel en el manejo de pacientes con sospecha de apendicitis: ¿pueden usarse como base? The best available evidence suggests that peritoneal irrigation with normal saline during LA does not provide additional benefits compared with suction alone in terms of IAA, SSI, and length of stay, but it may prolong the operative time.

Taking into consideration any kind of post-interventional complication (including treatment failure), the complication-free treatment success rate of antibiotic therapy was significantly inferior to the rate after surgery (68.4 vs 89.8%). A systematic review of all evidence available comparing appendectomy to NOM for uncomplicated AA in children included 13 studies, 4 of which were retrospective studies, 4 prospective cohort studies, 4 prospective non-randomized comparative trials, and 1 RCT.

The clinical results revealed that simple ligation was significantly superior to stump inversion [173]. Over the past 20 years, there has been renewed interest in the non-operative management of uncomplicated AA, probably due to a more reliable analysis of postoperative complications and costs of surgical interventions, which are mostly related to the continuously increasing use of minimally invasive techniques [16,17,18].

Value of early change of serum C reactive protein combined to modified Alvarado score in the diagnosis of acute appendicitis. IAA rate was similar between LA and OA. The effect size in favor of OA began to disappear after 2001, leading to an insignificant result with an overall cumulative OR of 1.32 (95% CI 0.84–2.10) when LA was compared with OA [140]. 2017;68:392–400. In pediatric patients with inconclusive US, we suggest choosing the second-line imaging technique based on local availability and expertise, as there are currently no strong data to suggest a best diagnostic pathway due to a variety of options and dependence on local resources [QoE: Moderate; Strength of recommendation: Weak: 2B]. reported that PCT had little value in diagnosing AA, with lower diagnostic accuracy than CRP and WBC, but a greater diagnostic value in identifying complicated AA [58]. In: The Cochrane Collaboration, editor. Sippola S, Grönroos J, Sallinen V, et al. 1-s2.-S1198743X20303037-main.en.es. The failure rate was 15%. Ann Emerg Med.

(failure rate, 47%), Svensson et al. highlighted the value of CRP ≥ 10 mg/L as a strong predictor of AA in children < 6 years old [57]. We recommend against postoperative antibiotics for patients with uncomplicated appendicitis [QoE: High; Strength of recommendation: Strong; 1A]. Similarly, in the multivariate logistic regression analysis by Almstrom et al., increased time to surgery was not associated with increased risk of histopathologic perforation, and there was no association between the timing of surgery and postoperative wound infection, intra-abdominal abscess, reoperation, or readmission [132]. 2022 Dec 27:1-5. doi: 10.1007/s12519-022-00656-9. 2017;32:19–28. una búsqueda bibliográca relacionada con Esas pregunas se realizaron hasa abril de 2015 Comentarios.
