Abstract
Median arcuate ligament syndrome (MALS) is characterized by the compression of the celiac trunk by the median arcuate ligament, leading to abdominal symptoms such as pain, nausea, and vomiting. While its exact cause remains unclear, theories propose vascular or neurogenic origins. This case study outlines a 24-year-old male with MALS experiencing postprandial epigastric pain, weight loss, gastroparesis, gastric dysrhythmias, and rapid gastric emptying. The patient presented with a three-month history of upper abdominal pain, particularly postprandial, relieved by vomiting, resulting in loss of appetite and significant weight loss of approximately 13 kg. He also reported increased stool frequency with yellowish discoloration but lacked alarming symptoms. Physical examination revealed mild dehydration and icterus but no significant abdominal findings. Subsequent investigations included CT angiogram, upper GI endoscopy, and 99m Tc Sulphur Colloid scintigraphy. CT angiogram findings indicated severe MALS affecting the right kidney and coeliac artery, with compression, stenosis, and arterial collaterals. Upper GI endoscopy showed grade B distal esophagitis/antral gastritis. 99m Tc Sulphur Colloid scintigraphy revealed rapid gastric emptying, with a notably faster half-emptying time compared to the normal range.
DISCUSSION: Published literature and discussion surrounding MALS revolves around diagnostic challenges and potential etiologies, with theories suggesting either nerve dysfunction or mesenteric ischemia. Advanced imaging techniques like CT angiography play a crucial role in visualizing characteristic artery compression. The observation of rapid gastric emptying suggests potential involvement of reflux or gastritis. Moreover, the interplay between MALS and Gilbert syndrome, alongside the possibility of nerve plexus compression leading to delayed gastric emptying, underscores the complexity of this condition.This case emphasizes the need for comprehensive investigation and management strategies tailored to individual patients with MALS. Treatment options may include surgical interventions such as laparoscopic or robotic median arcuate ligament release, aimed at alleviating symptoms and improving quality of life.
