The pregnancy was initially misdiagnosed as a dichorionic diamniotic intrauterine twin gestation. At 11 weeks 5\u2009days of gestation, she presented with abdominal pain. Ultrasonography revealed a viable intrauterine fetus and a second gestational sac in the left interstitial region, with moderate haemoperitoneum. Emergency laparoscopy confirmed rupture of the interstitial ectopic with 1500\u2009mL of haemoperitoneum. The ectopic sac was excised, and the uterine defect was repaired using a purse-string suture technique. Laparoscopy provided a minimally invasive approach with effective haemorrhage control. The intrauterine pregnancy progressed and culminated in the live birth of a preterm infant at 33 weeks 1\u2009day. This case highlights the diagnostic challenges of interstitial heterotopic pregnancy and underscores the role of timely laparoscopic intervention in achieving a rare but successful maternal and neonatal outcome.<\/jats:p>","DOI":"10.1136\/bcr-2025-266998","type":"journal-article","created":{"date-parts":[[2025,9,22]],"date-time":"2025-09-22T04:25:21Z","timestamp":1758515121000},"page":"e266998","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Laparoscopic
