A primary intestinal lymphangiectasia patient diagnosed by capsule endoscopy and confirmed at surgery: A case report

Table 1 Clinical manifestations of the patient

Main clinical manifestations	Chronic diarrhea, lower limb edema, upper abdominal pain.
Laboratory possitive findings	Lymphocytes: 1.0 × 103/dL, albumin: (19.5-24.5) g/L, IgG: 407.0 mg/dL, IgM: 40.4 mg/dL, TSH (RIA): 5.58 mIU/L, freeT3 (RIA): 1.24 pmol/L, freeT4 (RIA): 4.54 pmol/L.
Endoscopy findings	Basically normal
Image findings	Abdominal computer tomography (CT) (Figure 1) showing thickening of sinus ventriculi and jejunal mucosa, and the sign of chronic cholecystitis; ECT of lymphatic system showing no obviously abnormal.
Capsule endoscopy fingding	Diffuse dilatation of lymphatic vessels (Figure 2A and B), thickening of intestinal villi. The dilatation of lymphatic vessels was more obvious in the middle and lower parts of the intestine. The dilated lymphatic vessels presented as coral and were mixed with the dilated capillaries.
Operation finding	Adhesion of greater omentum and abdominal wall. Gallbladder was enlarged and had multiple cholecystolithiasis, diffuse intestinal lesions and obviously dilated lymphatic vessels in the intestinal wall, most severe at the end of ileum.
Pathological findings	Dilated lymphatic vessels in the villi, submucosal and outside of the intestinal wall.
