Methods： Atotal of 109 eyes in 109 cases ofcanalicular laceration were repaired with three types of silicone intubations, among which 23 with one-passage canalicular intubation, 51 with double-passage canalicular intubation, and 35 with circular canalicular intubation. The average follow-up period was 12-15 months. Results： The wound/junction of the lacrimal canaliculi was ruptured in 5 cases （9.80%） of the double-passage group, 3 cases （8.57%） of the circular group, and 8 cases （34.78%） of the one-passage group. The rupture incidence of the one-passage group was significantly higher than that of the other two groups （ χ^2=9.416, P〈0.01）. During the inmbation, canaliculitis was observed in 12 cases （23.53%） of the double-passage group, while only 3 cases （8.57%） in the circular group and 8 cases （34.78%） in the one-passage group. The circular group had significantly lower incidence of canaliculitis than the other two groups （ χ^2=6.095, P〈0.05）. After extubation 6 months after laceration repair, the lacrimal passage remained patent with canalicular irrigation in 46 cases （90.20%） in the double-passage group, 30 cases （85.71%） in the circular group and 15 cases （65.22%） in the one-passage group. Six months after surgery, the canalicular patency in the one-passage group was significantly lower than that of the other two groups （ χ^2=7.390, P〈0.05）. Conclusions： Circular canalicular intubation is more stable and has less surgical complications than the doublepassage and one-passage canalicular intubations. It is also more effective clinically 12-15 months after laceration surgery.展开更多

Methods： Eighty-seven patients （including 87 eyes） suffering from canalicular laceration were randomized into two groups： 41 patients treated with traditional pigtail probes （Group A） and 46 with modified pigtail probes （Group B）. During the reconstruction of the lacerated canaliculi, the traditional pigtail probe and the modified pigtail probe were used respectively to seek for the nasal cut ends of lacerated lacrimal canaliculi. Peripherally inserted central catheter （PICCTM） silicone tube with diameter of 0.95 mm was intubated as a stent for 4-6 months. The surgical outcomes were retrospectively analyzed after stent removal. Results： In Group B, the primary success rate of searching the nasal cut ends of lacerated lacrimal canaliculi was 93.48% （43/46） and the final success rate was 97.83% （45/46）. No false passage formed in Group B. Statistical sig- nificance was found between Group A and Group B as the primary success rates of searching the nasal cut ends （ x^2 = 10.522, P〈0.01） and the false passage forming rates were concerned （ x^2=4.704, P〈0.05）, whereas no significance was found between the two groups as the final success rates were concerned （ x^2=0.007, P〉0.05）. The mean time of searching the nasal cut ends of lacerated lacrimal canaliculi in Group B was （5.02±2.73） minutes and the mean time of operation was （33.90±4.84） minutes, and both were significantly shorter than those of Group A （t1=9.779, t2=10.700, P〈0.01）. The cure rate of Group B was 95.65%, though higher than that of Group A, no statistical significance was found （Z=-1.007, P〉0.05）. Totally, 2 patients （2.30%） were found to be absent of common canaliculus and underwent bicanalicular nasal intubation in the two groups. Conclusions： Pigtail pr展开更多
