This video demonstrates a diagnostic hystero-laparoscopy for infertility with hysteroscopic septoplasty for a small uterine septum. The procedure begins with vaginoscopic hysteroscopy, showing normal uterine cavity assessment before proceeding to diagnostic laparoscopy and chromopertubation, which confirms bilateral tubal patency. After methylene blue injection, the septum becomes clearly demarcated, allowing precise cold-scissor resection. The surgeon explains the correct endpoint of septoplasty, emphasizing gradual resection while preserving a slight fundal indentation to avoid excessive cutting. The video provides practical, evidence-based tips for safe and fertility-enhancing hysteroscopic surgery.
