Abstract: Objective To evaluate clinical effect of single-site umbilical laparoscopy in the treatment for inguinal incarcerated hernia in children. Methods Retrospective reviews were conducted for the clinical data of the 105 children of inguinal incarcerated hernia during January 2010 to August 2014. According to different operative approach, single-site laparoscopic surgery group(SLS ,n=56) and open surgery group(OS，n=49) were assigned and compared .The follow –up period was 6-36 month. Results Operation underwent successfully in both groups .The average operative duration had significant difference , which was (33.73±4.41)min for OS versus (25.13±4.82)min for 48 cases in SLS(p<0.01) ; the operative duration of other 8 cases in SLS was(32.25±2.18)min, because of discovery occult inguinal hernia and treating bilateral hernia. The average operative blood loss was (3.18±2.90)ml for OS versus (1.73±0.88)ml for SLS(p<0.01).The hospitalization duration was (4.22±1.16)d for OS versus (3.50±0.97)d for SLS(p<0.01). The postoperative complication were 24.5% for OS and 8.9% for SLS. Conclusion Single-site umbilical laparoscopy is safe and efficacious for inguinal incarcerated hernia in children .It offers many advantages such as mini-invasiveness , quick recovery ,fewer complication and discovery of occult inguinal hernia.
