This surgical technique article presents a step-by-step dissection of the pelvic sidewall anatomy to enhance gynecological knowledge and safety. The authors demonstrate ten specific steps for dissecting this region, emphasizing its critical role in complex procedures such as lymphadenectomy for uterine or cervical cancer staging. Additionally, the text highlights the importance of these anatomical skills for managing parametrial endometriosis and performing bilateral internal iliac artery ligation during severe postpartum hemorrhage. This paper is centrally about endometriosis — specifically regarding the anatomical knowledge required for safe dissection in cases of parametrial disease.

Abstract

Gynaecology is a vast speciality, with increasing sub specialisation in recent years, including maternal and fetal medicine, reproductive medicine and infertility, gynecological oncology, uro- gynaecology, and minimally invasive benign gynaecology among others.[1] Endometriosis surgery is another rapidly evolving field, and along with gynaecological oncology, is demanding of extensive knowledge of pelvic anatomy as well as upper abdomen anatomy. Even for benign gynaecology with large broad ligament fibroids, or intractable PPH in Obstetrics, bilateral internal iliac artery ligation bilaterally by pelvic sidewall dissection skills, is mandatory and lifesaving.[2,3] This surgical technique article depicts step by step dissection (10 steps) of the pelvic sidewall and anatomy demonstration for safe completion of surgery, whether in uterine/ cervical cancer staging surgery with lymphadenectomy, or parametrial endometriosis or bilateral internal iliac artery ligation during PPH not controlled medically.
