Objective

To evaluate the clinical results with modified tubal ligation method.

Methods

From 1983 to 1992, 700 cases of modified tubal ligation operation with tubes cut and overlapped were performed in our hospital, and this was compared with 602 cases of Pomeroy's and 502 cases of modified Uchida's method. Patients were followed at 6 months, 2 and 5 years. Pregnancy rates, menstruation disturbances, lower abdominal or back pain, and leucorrhea were observed.

Results

Patients with modified tubal ligation method had a pregnancy rate of 0.43%, which was significantly lower than that of Pomeroy's 1.50% (P < 0.05). The modified method group also had few complications. The occurence rate of menorrhage and prolonged bleeding were apparently lower than that of Pomeroy's too (P < 0.01).

Conclusion

This modified tubal ligation method is more effective and practicable than Pomeroy's and modified Uchida's method.
