Congenital abdominal cystic lymphangiomas: what is the correct management?
BACKGROUND
Intraabdominal cystic lymphangioma is a rare benign lesion with a variable clinical presentation. The aim of this study was to evaluate the natural outcome of this lesion and to propose a decision-making protocol for antenatal suspected intraabdominal lymphangioma. We also would like to emphasize the role of laparoscopy in treatment.


METHODS
This retrospective study examined 14 cases of intraabdominal cystic lymphangioma in children underwent to our observation, at the Pediatric Surgery Department in Lapeyronie Hospital, Montpellier between 1996 and 2007.


RESULTS
Of the 14 patients, 12 were operated on (7 by laparoscopy and 5 in open surgery). In 2 patients we didn't perform intervention because the lesion was localized in the mesenteric root: we observed a regression of the lesion on US-scan.


CONCLUSIONS
The intraabdominal cystic lymphangioma is a rare lesion which is now sometimes suspected on antenatal US scan; consequently we observed at the present time an increasing number of lesion potentially asymptomatic: in these case the management has to be established and a risk-benefit balance has to be made before a surgical intervention. Our experience is limited to a small number of cases, and it is too premature to describe any final conclusion; however our suggestion is that clinical course of cystic abdominal lymphangioma is unknown, and we propose that if no complication occurs, a clinical and ultrasonographic monitoring should be done in case of mesenteric root localisation.
