ABSTRACT
Objective To investigate the clinical efficacy of two different single orifice laparoscopic surgeries for patent processus vaginalis in children. Methods From August 2013 to June 2015,there were 84 children with patent processus vaginalis in the First Affiliated Hospital of Guangxi University of Science and Technolgy. They were divided into two groups ( A and B ) randomly according to different laparoscopic surgeries. Group A:used ordinary micro?laparoscope, single orifice, and double channel. Group B:used Li Xun nephroscope,single orifice,single channel. Both two groups′ the high ligation of the sheath was performed with the aid of the auxiliary forceps in the mirror under surveillance. The mean unilateral operation time, mean postoperative hospitalization duration,complications and recurrences of two groups were compared. Results All children underwent successful laparoscopic surgery,without transfering to open surgery,and unilateral operation time was (12. 53±3. 22) min for group A,(10. 16±2. 79) min for group B,the difference was significant(P=0. 037). The mean postoperative hospitalization duration was (2. 29±0. 57) d in group A,(2. 25±0. 55) d in group B, the difference was not significant ( P= 0. 671 ) . There was no complication and recurrence in two groups. Conclusion laparoscopic percutaneous extraperitoneal closure use Li Xun nephroscope,single orifice, single channel for children is safe and effective,and it is more convenient and less invasive than the conventional micro?laparoscope.
