Surgical management of hiatal hernia vs medical therapy to treat bleeding Cameron lesions: a systematic review and meta-analysis.
Synthesis in Surgical endoscopy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionCameron lesions (CL) are an under-recognized cause of gastrointestinal bleeding. Diagnosis is often impaired by technical difficulty, and once diagnosed, management remains unclear. Typically, patients are medically managed with proton pump inhibitors (PPI). Small studies have demonstrated improved therapeutic success with surgical management, hypothesizing that reversing mechanical gastric trauma and ischemia allows CL healing. This systematic review and meta-analysis aim to compare therapeutic success of surgical versus medical management of Cameron lesions (CL). METHODS AND PROCEDURES: A comprehensive search and systematic review selected manuscripts using the following inclusion criteria: (1) Endoscopically diagnosed CL (2) Treated surgically (3) Follow-up for resolution of anemia or CL (4) n ≥ 5 (5) Excluding non-English, animal, and studies with patients < 18 years old Meta-analysis was performed to compare resolution of CLs with medical and surgical therapy.
resultsSystematic search retrieved 1664 studies, of these, 14 were included (randomized controlled trial = 1; prospective = 2; retrospective = 11). Patients had a mean age of 61.2 years (range 24-91) and were more often female (59.3%). Follow-up was between 3 and 120 months, and 82.9% of patients had hernias > 5 cm. Surgical management was associated with therapeutic success (OR 5.20, 1.83-14.77, I
conclusionsThis is the first systematic review comparing surgical and medical treatment of CL. Surgical management significantly improved therapeutic success. Our study supports therapeutic benefit of surgery in these patients.
