Chronic Appendicitis: Possible Differential Diagnosis in Patients with Chronic Abdominal Pain
Open accessAbstract
In the emergency department, patients frequently present with abdominal pain, with a variety of different causes ranging from intra‐abdominal to extra‐abdominal and retroperitoneal pathologies which can affect all age groups. Chronic appendicitis is a rare medical condition characterized by less severe and continuous abdominal pain and a clinical picture lasting longer than 1‐2 days and extending over months, even years, and it is not always possible to consider it as a preliminary diagnosis. We represent a case report of chronic appendicitis where the patient’s clinical picture led the diagnostics and treatment in different directions and delayed the diagnosis. Namely, our patient was radiologically diagnosed with a collection of denser content retroperitoneally in the right lower quadrant of the abdomen, which in the first place was not related to possible appendicitis, regarding complaints. The existence of chronic appendicitis is a diagnosis unfamiliar to many clinicians and has no official diagnostic criteria. After diagnosis, treatment usually begins with antibiotics, and the next most common step is surgery. The optimal treatment for this condition is unknown. With this case report, we wish to draw attention to chronic appendicitis as a possible differential diagnosis in patients with chronic abdominal pain.

In the citing paper
“Chronic appendicitis is a rare and often debated clinical entity characterized by prolonged or recurrent inflammation of the appendix, typically presenting with vague, intermittent right lower quadrant abdominal pain and sometimes accompanied by mild gastrointestinal symptoms such as nausea, bloating, or changes in bowel habits.”

“Importantly, these conditions can coexist, further complicating clinical interpretation and emphasizing the need for careful intraoperative evaluation [8,10].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
