Research On Pregnancy Outcome Of Different Tubal Classification By Laparoscopy And Analysis Related Factor

Objective: To Research on pregnancy outcome of different tubal classification bylaparoscopy and analysis on related factor. Methods: The120patients who fallopian tubeswere blocked at far end underwent the laparoscopy from2010June to2012January inour center were analysed retrospectively. Salpingostomy or tubal proximal burning offcombine the distal ileostomy was operated according to different tubal classification bylaparoscopy. Compare the postoperative pregnancy outcomes in different grades，Comparethe IVF-ET pregnancy outcomes in different grades and related factors of grading. Results:In120patients which classification by strict standard,there are17cases in level Ⅰ, thereare31cases in level Ⅱ, there are32cases in level Ⅲ, there are40cases in level IV. Withinfollow-up period, pregnancy rate by nature of class I was47.06%(8/17), class Ⅱwas35.48%(11/31), class Ⅲwas6.25%(2/32), class IV was0%(0/32). Pregnancy rate oflevelⅠ a nd Ⅱ was obviously higher than that of the levelⅢ and IV (P <0.01). Thepregnancy rate of grade Ⅲ and IV of hydrosalpinx recurrence for IVF-ET before tubal burning offwere7.69%（1/13）and were46.15%（6/13）after tubal burning off. Pregnancy rate after tubal burningwas obviously higher than before tubal burning off (P <0.05). The pregnancy of gradeⅠ a ndⅡ forIVF-ET was9case （36%,9/25）,the pregnancy of grade Ⅲ and IV for IVF-ET was20case（30.76%,20/65）,there were no statistically significant difference (P>0.05). Thehistory of pelvic inflammatory disease, abortion, premarital sex and the time of infertilitywere highly correcated with tubal classification,(P>0.05). Conclusions: The cases ofdistal fallopian tube obstructive patients undergoing laparoscopic should be classificatedand choose different treatments according to the rating results.
