Objective To retrospectively analyze the laparoscope-assisted diagnosis and treatment for small intestinal atresia and stenosis in children.Methods Between September 2009 and February 2010,12 infants with small intestinal atresia and stenosis underwent laparoscope-assisted surgery at this center.Among the patients,1 was diagnosed as jejunum stenosis,2 as type I duodenum atresia,3 as typeⅡ atresia(25%),and 6 as type Ⅲ atresia(50%).No evident dilated abdomen was noted on the patients with jejunum stenosis or type I duodenum atresia,and the laparoscopic operations were performed to remove the septum and restore intestinal continuity.(ha the patients with type ⅡandⅢatresia,the bowel dilated evidently,laparoscopic inspection was performed to identify the location and the type of the malformations,and then the proximal and distal ends of the atresia were exteriorized through the umbilical port site for end-to-oblique anastomosis.Results The operative time for jejunum stenosis and type I duodenum atresia ranged from 80 to 100 minutes(average,92 minutes).The operative time for typeⅡand type Ⅲ atresia ranged from 40 to 65 minutes(average 48 minutes).The incision of umbilical port was 1.5-2cm long.One premature infant was abandoned by the parents,all the other cases recovered from surgery.Feeding started between postoperative day 3 and 7.No dilated abdomen and vomit was noted.The patients were discharged from hospital between postoperative day 9 and 16.No patients died after surgery.Eleven patients were followed-up for 1-6 months,no severe complications was noted.Conclusions Laparoscope-assisted surgery is minimally invasive and produces good outcomes in the diagnosis and treatment for congenital intestinal obstruction.
