Objective:
To provide a comprehensive, step-by-step presentation of the laparoscopic resolution of ectopic pregnancy within a rudimentary uterine horn.
Design:
A detailed demonstration of the laparoscopic technique presented through narrated video footage.
Setting:
Pregnancy occurring in the rudimentary horn of a unicornuate uterus represents a rare form of ectopic pregnancy [1]. This condition is associated with a high risk of uterine rupture. Early detection is crucial for effective management and prevention of potential complications [2,3]. In this manuscript, we present a case study of a patient diagnosed with ectopic pregnancy in a rudimentary horn, who underwent successful laparoscopic resection.
Interventions:
Ten main steps were identified and described in detail during the laparoscopic resection: Step 1: identification of the anatomy; Step 2: uterine mobilization; Step 3: Open retroperitoneum; Step 4: Coagulation and section of left round ligament; Step 5: Bladder dissection; Step 6: Identification of vessels; Step 7: Coagulation and section of left utero-ovarian vessels; Step 8: Coagulation and section of uterine vessels; Step 9: Section of uterine septum; Step 10: Specimen removed.
Conclusion:
This publication offers a detailed and instructive account of the laparoscopic resection of ectopic pregnancy within a rudimentary uterine horn. The stepwise approach demonstrated in the accompanying video contributes to a deeper understanding of this complex surgical technique. VIDEO ABSTRACT.
