Clinical Presentation, Diagnostic Approach, and Management of Symptomatic Gastrointestinal Lipomas
Bibliographic record
Abstract
Gastrointestinal (GI) lipomas are a rare form of benign submucosal neoplasm composed of mature adipose tissue. These lesions can grow anywhere in the GI tract, with a higher prevalence observed in the colon and the small intestines. Owing to their relative rarity and asymptomatic nature, the true incidence and prevalence remain unknown. GI lipomas can present with dysphagia, abdominal pain, intestinal obstruction, or GI bleeding, prompting further workup and interventions. On computed tomography and magnetic resonance imaging, GI lipomas typically appear as ovoid/spherical, sharply demarcated, and homogeneously hypodense lesions. On endoscopy, lipomas appear as smooth mucosal protrusions and, rarely, with ulceration. In some cases, an endoscopic ultrasound may be used to confirm diagnosis, staging, or pre-operative planning. Asymptomatic lipomas are managed conservatively using periodic imaging or endoscopy. Symptomatic lipomas, however, require endoscopic or surgical resection, and endoscopic techniques are preferred because of their non-invasive nature. Surgery is typically reserved for giant lipomas or more complex cases. There is a paucity of data regarding the clinical features and management of symptomatic GI lipomas. The current evidence is retrospective, in the form of case reports and conference abstracts. In this review, we discuss the clinical presentation, diagnostic approach, and management of symptomatic GI lipomas.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
