Oesophageal pneumatosis: computed tomographic characteristics in three dogs (2018-2021).

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
backgroundOesophageal pneumatosis (OP) is defined as the presence of gas within the oesophageal wall. The description of this condition in veterinary medicine is currently lacking. The pathogenesis of alimentary tract pneumatosis remains unclear. Current literature describes that access of gas into the oesophageal wall may occur by one or a combination of the following mechanisms: mucosal disruption, increased intra or extra-luminal pressure or dissection of gas from an extra-oesophageal source.
objectivesThe aim of this multi-centric case series was to describe the computed tomography (CT) findings of OP in dogs.
methodsThree adult dogs were included. One dog presented with gastrointestinal signs and general malaise while the other two presented with spontaneous facial and cervical subcutaneous emphysema.
resultsCT revealed different degrees of intramural gas along the oesophageal wall in all cases. The first dog was diagnosed with emphysematous gastritis based on the presence of gastric pneumatosis paired with compatible clinicopathological and endoscopic findings. This dog was successfully treated with antibiotics. The remaining two dogs were diagnosed with spontaneous pneumomediastinum and required no surgical or medical treatment.
conclusionsIn all cases with OP, there was concurrent gastric pneumatosis. Gas extensively and circumferentially distributed with a banded shape along the oesophageal wall was present in patients with presumed mural gas dissection because of pneumomediastinum. Conversely, a focal and mild amount of mural gas with a tubular shape was identified in the distal segment of the oesophagus in the patient with emphysematous gastritis.
