An uncommon spontaneous right distal tubal pregnancy post bilateral laparoscopic sterilization

<jats:title>Abstract</jats:title>

<jats:title>Rationale:</jats:title>
<jats:p>Tubal sterilization as a contraception method has a high success rate; however, it also carries a low risk of incidental pregnancy. A majority of these pregnancies are ectopic. In this study, we report a rare case of spontaneous right distal tubal pregnancy after bilateral laparoscopic tubal sterilization.</jats:p>

<jats:title>Patient concerns:</jats:title>
<jats:p>A 36-year-old woman who had undergone bilateral laparoscopic tubal sterilization presented with abdominal pain and a positive test for pregnancy.</jats:p>
</jats:sec>
<jats:sec>
<jats:title>Diagnosis:</jats:title>
<jats:p>Ectopic pregnancy was suspected based on absence of gestational sac in the uterine cavity on ultrasound and elevated beta-human chorionic gonadotropin (β-hCG) level.</jats:p>
</jats:sec>
<jats:sec>
<jats:title>Intervention:</jats:title>
<jats:p>Since the patient had unstable vitals, emergency laparoscopic surgery was performed, which revealed a right distal fallopian tube pregnancy. We performed a complete bilateral residual tubal stump excision.</jats:p>
</jats:sec>
<jats:sec>
<jats:title>Outcomes:</jats:title>
<jats:p>The patient recovered well after surgery, with a reduction in β-hCG level, and was discharged after 3 days.</jats:p>

<jats:title>Lessons:</jats:title>
<jats:p>To ensure complete sterilization, the gap at the excised end needs to be adequately widened and enhanced with electro-destruction to prevent formation of a fistula.</jats:p>
