Tubal anastomosis after tubal sterilization: a review
- 410 Downloads
To evaluate various techniques for restoring tubal patency after sterilisation.
A search strategy was designed, and for each subject either thesaurus terms (MeSH descriptors) or terms from the title or summary were used.
Mean length of hospital stay following laparoscopy seems to be shorter in comparison with laparotomy (3.3 vs. 6.1 days, P < 0.05). Rate of conversion to laparotomy is 5%. Pregnancy rates observed are between 54 and 88% for laparotomy and 31–85% for laparoscopy. Mean time to conception was between 2 and 9.6 months. Most pregnancies occurred in the 2 years following restoration of tubal patency (cumulative conception rate 80% at 12 months). Young age (<35 years), type of ligature (rings), how recently the ligature was done (<8 years), the anastomosis site (in the middle of the tube) and a good length of remaining tube (>7 cm) are the factors that govern whether there can be good restoration of tubal patency. Ectopic pregnancy rates observed are between 1.7 and 12% for laparotomy and 0–7% for laparoscopy. There are no randomised or quasi-randomised studies comparing tubal anastomosis and in vitro fertilization.
There are few good-quality controlled studies in this area. Results of restoration of tubal patency seem to be comparable, regardless of the route of approach (laparotomy or laparoscopy).
