A metanalysis confirmed that use of endo-loop to secure the appendicular stump during LA takes longer than endo-GIA but it is associated with equal hospital stay, perioperative complication rate, and incidence of intra-abdominal abscess [122]. In the EU, only around 12.9 % of patients undergo pre-operative CT imaging [51]; which is typically reserved for elderly patients who might have cancer, atypical or delayed presentations or those who have suspected appendicular masses or abscesses. In-hospital delay of more than 12 h, age over 65 years, time of admission during regular hours, and the presence of co-morbidity are all independent risk factors for perforation. 3rd ed. (1,4, 7) Statement 6.1: The incidence of unexpected findings in appendectomy specimens is low but the intra-operative diagnosis alone is insufficient for identifying unexpected disease. No major benefits have also been observed in laparoscopic appendectomy in children, but it reduces hospital stay and overall morbidity. Bhangu A, et al. Surg Endosc. Primary or secondary closure of the wound? Recently, a prospective randomized trial on 518 patients with complicated intra-abdominal infection, including also complicated appendicitis, undergoing adequate source control demonstrated the outcomes after fixed-duration antibiotic therapy (approximately 4 days) were similar to those after a longer course of antibiotics (approximately 8 days) that extended until after the resolution of physiological abnormalities [160].

Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. Individual validation studies occasionally reported lower sensitivity, questioning the ability of the Alvarado score to reliably exclude appendicitis with a cut-off score of less than five [12, 13].

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]. reported the incidence of unexpected findings in the histopathological examination of the surgical specimen after appendectomy as 0.5 % of benign neoplasm, 0.2 % of malignant neoplasms, 0–19 % of parasitic infection, endometriosis in 0 % and granulomatosis in 0–11 % of cases.

Endoloops were at least as safe and effective as endostapler also in paediatric population, without stump leaks nor differences in SSI and IAA in the group of non perforated appendicitis, whereas for perforated appendicitis, endoloops were perhaps safer than endostapler (IAA incidence 12.7 % vs. 50 %, OR 7.09) [123].

Radiographics. Ann Emerg Med. INTRODUCCIÓN. Laparoscopic appendectomy should represent the first choice where laparoscopic equipment and skills are available, since it offers clear advantages in terms of less pain, lower incidence of SSI, decreased LOS, earlier return to work and overall costs. Addiss DG, et al. The duration of surgery pooled by eight reviews was 7.6 to 18.3 min shorter using the open approach and the risk of abdominal abscesses was higher for laparoscopic surgery in half of six meta-analyses. A systematic review of clinical prediction rules for children with acute abdominal pain. In addition, especially in state funded health systems, where all expenditure has to be based on evidence, it is hard to justify after hours surgery for uncomplicated appendicitis. Terasawa T, et al.

Naguib N. Simple technique for laparoscopic appendicectomy to ensure safe division of the mesoappendix. Acute appendicitis (AA) is a common cause of acute abdominal pain, which can progress to perforation and peritonitis, associated with morbidity and mortality. Others disagree and found that delaying surgical intervention did not put the patient at risk and may have actually improved patient outcomes [74]. Surgery. Meropenem versus tobramycin with clindamycin in the antibiotic management of patients with advanced appendicitis. In a large retrospective cohort study of 32,782 patients who underwent appendectomy for acute appendicitis (available through the American College of Surgeons National Quality Improvement Program), 75 % of patients underwent operation within 6 h, 15 % between 6 and 12 h and 10 % of patients experienced a delay of more than 12 h (mean 26.07 h (SD 132.62)). Nonetheless, the clinical significance of these early and/or mild forms of microscopic appendicitis is still unclear at present. Because of its consistent morbidity, after successful conservative management, the routine indication to interval appendectomy is justified only in case of persistent or recurrent symptoms, and should be avoided in asymptomatic patients [148]. Google Scholar. The systematic review by Hall et al. PubMed Central  In the intermediate risk group an abdominal ultrasound would be the first line in imaging. 2013;27(5):1594–600.

One review showed no difference in mortality [86]. Similarly, others have found that the trends for non-perforating and perforating appendicitis radically differ and it is unlikely that perforated appendicitis is simply the progression of appendicitis resulting from delayed treatment [75]. 2013;148(8):779–86. World J Surg. Br J Surg. 1992;58(4):264–9. In the USA, logistics and legal concerns unfortunately impact our decision-making. Instead, irrigation usually adds some extra-time to the overall duration of surgery [105]. Apendicitis Fiorella Saldaña Alvarado. According to Ohle et al., the score’s performance is dependent on the cut-off value: a clinical cut-off score of less than five can be applied to 'rule out' appendicitis with a sensitivity of 99 % (95 % CI 97 – 99 %) and a specificity of 43 % (36 – 51 %), while a cut-off score of less than seven results in a sensitivity of 82 % (76 – 86 %) and a specificity of 81 % (76–85 %), suggesting it is not sufficiently accurate to rule in or rule out surgery. Right-sided diverticula occur more often in younger patients than do left-sided diverticula and because patients are young and present with right lower quadrant pain, they are often thought to suffer from acute appendicitis; it is difficult to differentiate solitary caecal diverticulitis from acute appendicitis.

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.

The timing of performing an appendectomy is a great matter of debate and our recommendations are that a short, in-hospital surgical delay up to 12/24 h is safe in uncomplicated acute appendicitis and does not increase complications and/or perforation rate, however surgery for uncomplicated appendicitis should be planned for next available list minimizing delay wherever possible.

Although LA is extremely useful especially as a diagnostic tool in fertile women, in can be used also in male patients, even if advantages over OA in this group are not clearly demonstrated [87]. doi: 10.1097/SLA.0b013e31811f3f9f.
