This educational lecture provides a comprehensive overview of the hysteroscopic management of abnormal uterine bleeding using the PALM-COEIN classification. Beginning with endometrial polyps, the video discusses the indications, techniques, and instrumentation for hysteroscopic surgery before progressing to submucous fibroids, fibroid polyps, and complex intramural lesions. It explains how to choose between hysteroscopic and laparoscopic surgery, emphasizing safe uterus-preserving techniques. The presentation also reviews endometrial hyperplasia, LNG-IUS, transcervical endometrial resection (TCRE), and chronic endometritis. Throughout the lecture, practical surgical videos are combined with evidence-based recommendations and clinical decision-making. It serves as an excellent learning resource for gynecologists interested in modern hysteroscopic management of AUB.
