Background/AimsMedian arcuate ligament syndrome (MALS) is known as chronic recurrent abdominal pain related to compression of the celiac artery by the median arcuate ligament. We aim to seek the specific mechanism of the pain by evaluating symptoms and radiological characteristics on abdominal CT scans.
MethodsWe analyzed 35 patients who visited the emergency room for recurrent abdominal pain after cholecystectomy. We classified the characteristics of patients as 4 clinical components and 2 radiological components. We defined the sum of weighted clinical scores and weighted radiological scores as nutcracker ganglion abdominal pain syndrome (NCGAPS) scores. We categorized the patients into 3 groups classified by the degree of NCGAPS scores. The 3 patients with top-3 NCGAPS scores were recommended for CT angiography.
ResultsWhen the suspicion was graded by NCGAPS scores, post stenotic dilatation was significantly different among all groups (P < 0.001). The clinical components of pain varied positional or respirational change and continuous pain were significantly different among all the groups (P < 0.01). NCGAPS scores can remarkably differentiate highly suspicious patients in comparison to simply combined scores. Only 1 patient in the highly suspicious group by NCGAPS scores took the CT angiography and was confirmed with NCGAPS.
ConclusionsWe suggest renaming MALS as NCGAPS, nutcracker celiac ganglion abdominal pain syndrome, to better explain the mechanism of the recurrent abdominal pain. Further studies on the diagnostic cutoff of clinical and radiological scores of NCGAPS are needed not to miss the diagnosis of NCGAPS.
