Clinical outcomes and ergonomics analysis of three laparoscopic techniques for Hirschsprung's disease

Table 2 Operative time among the three procedure groups relative to the age and transitional zone

Group	CLP(n = 30)	SILP(n = 28)	H-SILP(n = 32)
Patients < 1 yr of age, n	21	20	22
Operative time (min)	113 ± 23	109 ± 8	113 ± 12
Patients > 1 yr of age, n	9	8	10
Operative time	120 ± 15a	140 ± 7	119 ± 12a
Rectosigmoid colon, n	27	26	27
Operative time (min)	111 ± 20	114 ± 17	109 ± 20
Descending colon, n	3	2	5
Operative time (min)	152 ± 4a	176 ± 2	154 ± 4a

^aP < 0.05 vs SILP. CLP: Conventional laparoscopic pull-through; SILP: Single-incision laparoscopic pull-through; H-SILP: Hybrid single-incision laparoscopic pull-through.
