Serum beta-hCG regression after laparoscopic salpingostomy in the treatment of ectopic pregnancy in Thai women.

ABSTRACT

This is a descriptive study which reviewed the regression pattern of serum beta hCG in Thai women with ectopic pregnancy after laparoscopic salpingostomy. The study group included the medical records of 21 patients who underwent laparoscopic salpingostomy between January 1991 and August 2001. The results revealed that the regression of serum beta hCG in patients with ectopic pregnancy after laparoscopic salpingostomy was about 10, 100, 1,000 times at day 6, 20 and 35 after operation. The correlation between days after operation and serum beta hCG was in the equation of log (beta hCG difference) = -0.0671 (days after operation) - 0.6187. This estimation curve can probably be used to predict the normal serum beta-hCG regression after laparoscopic salpingostomy.
