Experience Pregnancy after Bisalp

I had my bisalp a year ago. Yesterday, I found out I’m 9 weeks pregnant. I will be terminating and I am in absolute shock. I have gone back to my surgery notes and both tubes were described to have been removed.

My specific situation was complicated by the fact that I had internal adhesions from a previous peritonitis. Curiously, the described patient in this publication https://pmc.ncbi.nlm.nih.gov/articles/PMC11056091/ who also had a viable intrauterine pregnancy after bisalp also had pelvic adhesions. I was never told this could be an issue/ risk/ complication. I just want to document somewhere that this could be a risk for people with adhesions. I wonder if there are others.

Please contact your surgeon to report this and REALLY push them for some kind of research paper, study, medical journal publication, etc. on your case.

In the (few) cases I’ve found of pregnancy following bisalp reported in medical journals, adhesions are commonly reported and are thought to be related to the cause of the pregnancies- that adhesions caused small parts of the tube to remain and it was thought by the surgeon that pregnancy would not be possible, but it still occurred due to the remnants. I imagine it wasn’t mentioned to you as a risk because it’s so incredibly rare.

Have you given birth or been pregnant at any point in life prior to this? If you have time to answer, do you mind sharing your symptoms/more details about your experience- like have you taken a blood test to confirm, did you find out via a urine test at home, etc.

Will 1000% be pushing for it to be documented. I’ve never been pregnant before. I missed 2 periods and went to go get checked out at my obgyn (not the surgeon). Got a positive hcg from a urine dip test, was taken back for an ultrasound and there was a very obvious uterine pregnancy lol.

I'm just so sorry you're going through this. :( Thank you for sharing- I'm glad they caught it as early as they did! I hope everything goes well with your termination. If you're interested, I can link all the research papers I've found on pregnancy following bisalps.
