Acute appendicitis, inflammatory appendiceal mass and the risk of a hidden malignant tumor: a systematic review of the literature

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 ...

(Aust N Z J Obstet Gynaecol. 2019;59:45–53) The most common emergency nonobstetric abdominal surgery performed in parturients is appendicectomy, which occurs in ∼0.3% of pregnancies. Establishing the diagnosis of appendicitis is more challenging in pregnant women as a result of the physiological changes of pregnancy and the many non-specific symptoms experienced during normal pregnancy. In addition, the use of ultrasound to make the diagnosis is less effective due to the presence of the gravid uterus and computed tomography scanning is sometimes avoided to prevent fetal radiation exposure. Appendiceal perforatio...

Conclusion: Although PMP is a relatively rare entity, radiologists must be aware of its possible imaging findings, common locations, and possible patterns of recurrence. The origin of the primary tumor should also be investigated. Future studies are needed in order to determine which preoperative imaging findings predict surgical outcomes and to characterize the main findings of radiological recurrence.Resumo Objetivo: Determinar as caracter ísticas de imagem mais frequentes do pseudomixoma peritonial (PMP), bem como os subtipos histológicos dos tumores primários. Materiais e Métodos: Foram revi...

CONCLUSIONS: The sensitivity and specificity of CT for diagnosing appendicitis in adults are high. Unenhanced standard-dose CT appears to have lower sensitivity than standard-dose CT with intravenous, rectal, or oral and intravenous contrast enhancement. Use of different types of contrast enhancement or no enhancement does not appear to affect specificity. Differences in sensitivity and specificity between low-dose and standard-dose CT appear to be negligible. The results of this review should be interpreted with caution for two reasons. First, these results are based on studies of low methodological quality. Second, the c...

We report two alternative therapeutic approaches: interval appendectomy and non-operative management. We conclude that these alternative approaches may be suitable for some patients with stump appendicitis. A review of the pertinent literature was done.

Children with suspected appendicitis generally undergo an ultrasound (most commonly) or a CT scan (rarely) as the first imaging study. At our hospital, patients with non-diagnostic ultrasound or CT scan results undergo a non-contrast (unenhanced), non-sedated MRI. We aimed to determine the accuracy of this study for this purpose in a large cohort of children.

Publication date: Available online 4 November 2019Source: Journal of Visceral SurgeryAuthor(s): A. Faul, A. Laforest, D. FuksSummaryAppendix intussusception is rare, can be responsible of chronic unexplained abdominal pain and is mostly associated with inflammatory changes or endometriosis. A 23-year-old woman with Crohn's disease was diagnosed invaginated appendix by CT-scan and colonoscopy after several acute atypical abdominal pain episodes. These episodes were suspected to be independent of the Crohn's disease and to be attributed to the intussusception itself. A resection combining ligation of the base by colonoscopy ...

A 29-year-old male presented with a 1-week history of nausea, vomiting, fevers, and chills. At presentation he was febrile, tachycardic, and exhibited right-sided abdominal pain. Initial workup revealed a white blood count of 13.1, bilirubin 4.3, and mild elevation of transaminases. Computed tomography (CT) scan of the abdomen and pelvis revealed a thickened distal terminal ileum, a dilated and inflamed appendix with an appendicolith (Fig 1), and a nonocclusive thrombus within the superior mesenteric vein (Fig 2).

CONCLUSIONInspection of the staple line, choosing the appropriate staple size and cartridge, and removing free malformed staples if seen should be employed during appendectomy to prevent rare but devastating complications.
