Clinical outcomes in patients with complicated appendicitis.
Article in Surgical endoscopy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundComplicated appendicitis (appendicitis with abscess, perforation, or generalized peritonitis) poses a significant burden on healthcare systems, with incidence up to 28-29%. Current management options include antibiotic therapy and up-front surgery, antibiotic therapy and percutaneous drainage, or antibiotic therapy alone. There is no consensus on treatment guidelines in current literature. This study aims to better define treatment algorithms for patients presenting with acute complicated appendicitis by evaluating clinical outcomes in those treated with or without surgery.
methodsWe performed a single-institution, retrospective review of 220 adult patients (≥ 18 years old) treated for acute complicated appendicitis from January 2017 to June 2022. Demographic and clinicopathologic variables were collected and analyzed. We compared patients who were managed non-operatively versus operatively. Regression modeling was used to determine factors associated with non-operative management (NOM) and those predictive of failure of NOM.
resultsOur analysis showed 26.3% patients with acute complicated appendicitis underwent NOM (n = 58), versus 73.6% underwent operative management at index admission (n = 162). Within the NOM group, 55.1% patients were treated with antibiotics alone (n = 32) versus 44.8% with percutaneous drainage (n = 26). Within the operative cohort, 88.7% of patients underwent appendectomy (n = 142). Age, body mass index, comorbidities, vital signs and laboratory values on admission were similar between both groups. Clinical factors predictive of initial NOM were perforation (OR 7.9, 95% CI 3.7-16.5) and phlegmon (OR 6.3, 95% CI 2.8-14.1) at presentation. Clinical factors predictive of failure of NOM requiring surgery on index admission or within 30 days was larger abscess and/or phlegmon size (OR 1.76, 95% CI 1.0-3.0).
conclusionThere may be a role in identifying clinical factors in patients with complicated appendicitis that favor non operative versus operative management. Larger abscess and/or phlegmon size could be a predictor of failure of NOM.
