腹部囊性淋巴管瘤非常罕见,大多数发生在婴幼儿,且为先天性,诊断十分困难。往往由压迫邻近器管产生腹痛,腹胀等症状,或因发现腹部包块而就诊。B超能帮助作出诊断,我院自1987年2月以来收治各个部位淋巴管瘤33例,其中位于腹腔内仅5例,兹报告如下。临床资料本组患儿年龄3个月～13岁,10岁以下24例占68.6％,位于软组内的淋巴管瘤28例,占84.8％,而且绝大多数在颈部(13例)占33.3％。而位于腹腔内淋巴管瘤5例,只占15.2％。(附表1)5例发病早期均因症状不典型多次就诊:辗转于内,外科。2例有腹痛,腹胀:1例有腹胀伴气急;余2例无明显症状。 4例为单囊完整切除,1例多囊合并感染、囊内出血,手术切除不彻底,术后二月复发。讨论一、病因探讨及意义: 淋巴管瘤由憎生的淋巴管所构成。多数是淋巴管的畸形或发育障碍,而不是真正的肿瘤。胚胎期 Abdominal cystic lymphangioma is very rare. Most of them occur in infants and are congenital. Diagnosis is very difficult. It is often caused by abdominal pressure, abdominal distension and other symptoms, or by finding abdominal mass. B ultrasound can help to make a diagnosis. Our hospital has treated 33 cases of lymphangioma in various sites since February 1987, of which only 5 cases are located in the abdominal cavity. We hereby report the following. The clinical data of this group were 3 months to 13 years old, and 24 patients under 10 years old accounted for 68.6%. There were 28 cases of lymphangioma in the soft group, accounting for 84.8%, and most of them were in the neck (13 cases). 33.3%. And in the intra-abdominal lymphangioma in 5 cases, accounting for only 15.2%. (Annex 1) 5 cases of early onset symptoms were not typical of multiple visits: phlegm transfer, surgery. Two patients had abdominal pain and abdominal distension: 1 patient had bloating with shortness of breath; the remaining 2 patients had no obvious symptoms. 4 cases were single-sacular complete resection, 1 case of polycystic infection, intracapsular hemorrhage, incomplete surgical resection, recurrence after 2 months. Discussion I. Etiology and significance: Lymphangioma is composed of axillary lymphatic vessels. Most are lymphatic malformation or developmental disorders, not true tumors. Embryonic stage
