(EL2, GoR B). 2008;22(9):1917–27. Furthermore, practice patterns may vary widely with regard to the amount and extent of irrigation and probably the common sense would suggest to avoid copious irrigation before achieving a careful suction first from every quadrant having purulent collections and to wash using small amounts of saline and repeated suction in order to avoid diffuse spreading of the infected matter into the remaining abdominal cavity, without forgetting to suck out as much as possible of the lavage fluid [108]. Ohle R, et al. Analysing the technical issues in performing an appendectomy, peritoneal irrigation does not have any advantages over suction alone in complicated appendicitis; there are no clinical differences in outcomes, LOS and complications rates between the different techniques described for mesentery dissection (monopolar electrocoagulation, bipolar energy, metal clips, endoloops, Ligasure, Harmonic Scalpel etc.). Kessler N, et al. Federal government websites often end in .gov or .mil. However, in case of appendix non-visualization on US, MRI is the recommended imaging exam, since it yields a high diagnostic rate and accuracy [41–43]. Conversely, appendicitis is very likely when the values of two or more inflammatory variables are increased [21]. La Guía de Práctica Clínica para el Tratamiento de la Apendicitis Aguda forma parte de las Guías que integrarán el Catálogo Maestro de Guías de Práctica Clínica, el cual se instrumentará a través del Programa de Acción Específico de Guías de Práctica Clínica, de acuerdo con las estrategias y líneas de acción que Am J Emerg Med.

In settings having availability of such resource, MRI can also be considered for pediatric appendicitis imaging being a non-radiative imaging modality potentially valuable in the setting of negative ultrasound. 2010;51(3):220–5. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

In 2005 a Cochrane meta-analysis supported that broad-spectrum antibiotics given preoperatively are effective in decreasing wound infection and abscesses. However, conditional CT imaging results in more false positives [9, 54]. Carroll PJ, et al. 19. J Am Coll Surg.

Two meta-analysis failed to prove the superiority of delayed primary skin closure in significantly reducing SSI (odds ratio 0.65; 95 % CI, 0.25–1.64; P = .36) [64] (risk ratio 0.89; 95 % CI: 0.46, 1.73) [130].

The lifetime risk of appendicitis is 8.6 % for males and 6.7 % for females; however, the risk of undergoing appendectomy is much lower for males than for females (12 vs. 23 %) and it occurs most often between the ages of 10 and 30, with a male:female ratio of approximately 1.4:1 [1]. This is based on the traditional model of appendicitis where initial obstruction causes inflammation and infection, and delay to operation allows increasing tension in the wall with ischemia, necrosis and perforation. As can be seen, the evidence is conflicting but recently higher level evidence has become available in the study by Bhangu et al. However, this means that 80 % of children may not need interval appendectomy. Acad Emerg Med. 2012;29(12):1013–4. Open navigation menu Close suggestionsSearchSearch enChange Language Surg Endosc.

(EL 4, GoR C), Statement 6.3: Surgeon’s macroscopic judgement of early grades of acute appendicitis is inaccurate. Actually, if this is related to the natural history of appendicitis or not is still unknown, but according to the authors these may be two distinct forms of appendicitis: the first one is a mild simple appendicitis that responds to antibiotics or could be even self-limiting, whereas the other often seems to perforate before the patient reaches the hospital. 2012;344, e2156.

Estimating pre-image likelihood of appendicitis is important in tailoring management: low-risk patients could be discharged with appropriate safety netting, whereas high-risk patients are likely to require early senior review with a focus on timely surgical intervention rather than diagnostic imaging [16].

According to the second model, only a few perforations can be prevented by a speedy operation after the patients have arrived at the hospital. In summary, The Alvarado score (with cut-off score < 5) is sufficiently sensitive to exclude acute appendicitis, nonetheless the ideal (highly sensitive and specific), clinically applicable, diagnostic scoring system/clinical rule remains currently out of reach.

A conditional CT strategy, where CT is performed after a negative US, will reduce number of CTs by 50 % and will correctly identify as many patients with appendicitis as an immediate CT strategy.

Nonoperative treatment with antibiotics versus surgery for acute nonperforated appendicitis in children: a pilot randomized controlled trial. Diagnosis of AA is made by clinical history and physical examination the typical symptoms and laboratory signs may be absent in 20–33 % of patients and, when they are present, can be similar to other conditions, especially in early stage [22, 23] and the diagnosis can be particularly difficult in children, elderly patients, pregnant and childbearing age women. Duration? In the patients with equivocal clinical picture, or equivocal imaging, or in those who have strong preferences for avoiding an operation or with major comorbid medical problems it is reasonable to treat with antibiotics first [72]. 2014;9:37.

Peritoneal closure versus no peritoneal closure for patients undergoing non-obstetric abdominal operations. Statement 1.2 The Alvarado score is not sufficiently specific in diagnosing acute appendicitis [EL 1, GoR A]. 2009;19(5):392–4. The analysis of the epidemiologic and clinical studies that elucidate the natural history of appendicitis performed by Andersson in 2007 showed that not all patients with uncomplicated appendicitis will progress to perforation and that spontaneous resolution may be a common event [36]. In conclusion, there is no strong current evidence as to the preferred modality of appendectomy, open or laparoscopic, during pregnancy from the prospect of foetal or maternal safety. CAS  Diagnosis of appendicitis in pregnancy. The Appendicitis Inflammatory Response (AIR) score has been proposed in 2008 by Andersson [6] and is based on eight variables, including C-reactive protein (CRP). J Am Coll Surg. Unfortunately most of these patients in the USA are seen by emergency physicians and tests are ordered before the surgeon is called. All the statements were discussed and approved during the 3rd WSES World Congress, held in Jerusalem on 6th July 2015. 2013;7, CD010424. Interestingly, the surgeon’s experience did not affect the disagreement rate. The literature does not clearly define the balance between advantages and disadvantages in this particular setting and the choice of the approach should be taken by the attending surgeon after a thorough discussion with the patient, balancing the advantages of laparoscopy vs. the theoretical risk of fetal loss and making clear the current lack of literature defining balance between advantages and disadvantages of laparoscopic appendectomy in pregnancy.

Peritoneal lavage and aspiration have been suggested by a low-powered study to be detrimental, but these conclusions are based on low-volume lavage and small numbers [104]; a definitive conclusion cannot be drawn, even though a LE 2 study in children [105] has not demonstrated advantages in terms of intra-abdominal abscesses (IAA) of >500 ml, although >6–8lt are needed to significantly lower the bacterial load [106]. Routine drainage has not proven its utility, with the exception of generalized peritonitis, and seems to cause more complications, LOS and transit recovery time [128], despite the widespread opinion that aspiration of the residual fluid after peritoneal lavage in the first 24 h postoperatively might lower the incidence of IAA in case of insufficient lavage [118]. The analysis did not find significant differences for treatment efficacy, length of stay or risk of developing complicated appendicitis [2]. In the Multicentre Appendectomy Audit by Strong et al., 138 out of 496 specimens (27.8 %) judged as normal by the operating surgeon were found to be inflamed at the histopathological assessment [139]. From the current available evidence, routine histopathology is necessary. Teixeira PG, et al. ANZ J Surg. La apendicitis es causada por un bloqueo en el interior del apéndice.
