Intestinal Malrotation With a Fixed Partial Volvulus in an Adult

A 44-year-old man had been suffering from nausea, vomiting and watery diarrhea for 5 days and was then admitted to Dankook University Hospital. He had suffered from several episodes of mild symptoms, including abdominal distension, loss of appetite, easy satiety, nausea, vomiting, and diarrhea throughout his lifetime, but most episodes had been ignored by him or physicians. An upper gastrointestinal series and a computed tomography scan revealed an intestinal malrotation with a volvulus. In order to untwist the small bowel in a counterclockwise direction to about 180 degrees, we had to perform not only a dissection of Ladd's band, but also a dissection of other adhesions between the mesocolon and the mesenteric vessel trunk. Surgical intervention needs to be performed for an old intestinal malrotation with any symptoms because the structural or morphological change proceeds as time passes, which is caused by fibrosis due to tension being repetitively applied to Ladd's band, leading to its contraction. Furthermore, a severe contraction may even lead to a fixed partial volvulus.
