| description | Introduction: Gastric volvulus is a rare cause of acute
or recurring abdominal pain in adults, with significant
mortality and morbidity. Gastric volvulus is rotation of
stomach along its axis, causing gastric outlet obstruction
and can result in ischaemia and infarction.
Aim: Evaluation of differentiating findings of organoaxial,
and mesenteroaxial types of gastric volvulus on
Multidetector Computed Tomography (MDCT).
Materials and Methods: This was a retrospective study
of 20 cases of radiologically suspected cases of gastric
volvulus, extracted by keyword search (gastric volvulus)
from our reviewed Teleradiology RIS/PACS between the
periods Nov-2014 to May-2017. The age group, gender
and presenting symptoms of cases were evaluated
and statistically analysed. Differentiating CT features of
organoaxial volvulus and mesenteroaxial volvulus were
evaluated and analysed.
Results: In our study, 80% cases were of the organoaxial
type of gastric volvulus, while the remaining 20% were of
mesenteroaxial type. Mean age of presentation was 77
years with higher incidence among older population. 65%
of the patients in our study were females. The majority
(85%) in our series presented with classical abdominal
pain, nausea and vomiting, and the presence of a hiatal
hernia. In our series MDCT was helpful in diagnosing
gastric volvulus based on abnormal axis of rotation (100%
of both OAV and MAV) and abnormal location of the pyloric
antrum above the fundus (85% of OAV). Pylorus lying
above the gastroesophageal junction is a differentiating
feature (100% of cases of MAV).
Conclusion: MDCT is useful in diagnosing gastric volvulus
as well as in differentiating OAV and MAV types by specific
findings such as axis of rotation of the stomach, position of
GEJ, pylorus, greater and lesser curvatures. |
