Challenges of cytoreduction in porta hepatis in surgery for advanced ovarian cancer.

Introduction: Advanced ovarian cancer often necessitates aggressive surgical intervention, including cytoreduction of the porta hepatis, which poses significant challenges due to the intricate anatomical structures involved. This surgical video aims to illustrate these challenges and demonstrate effective techniques for clearance of critical structures such as the portal vein (PV), common bile duct (CBD), accessory left hepatic artery (Acc. LHA), obliterated umbilical vein (OUV), inferior vena cava (IVC), and foramen of Winslow. Methods: The surgical procedure depicted in the video involved meticulous dissection and identification of anatomical landmarks to access the porta hepatis. Techniques for safe clearance of the PV, CBD, Acc. LHA, OUV, IVC, and foramen of Winslow were employed and are highlighted in detail. Emphasis was placed on preserving vascular integrity and minimizing intraoperative complications. Conclusions: The video demonstrates the complexities associated with cytoreduction of the porta hepatis in advanced ovarian cancer surgery and offers insights into overcoming these challenges. By utilizing precise surgical techniques and careful anatomical consideration, successful clearance of critical structures can be achieved, thereby optimizing patient outcomes and minimizing postoperative complications. This educational resource provides valuable guidance for surgeons encountering similar challenges in the management of advanced ovarian cancer.

Open total mesometrial resection for cervical cancer.

Introduction: Cervical cancer management often relies on surgical interventions, among which open total mesometrial resection (TMMR) has gained prominence. This abstract gives an insight into the technique of TMMR in the surgical treatment of cervical cancer. TMMR involves precise dissection of the mesometrium surrounding the cervix, aiming for optimal oncological outcomes while minimizing surgical morbidity. Methods or Technique: TMMR entails meticulous dissection of the mesometrium surrounding the cervix, following embryonic planes to ensure complete removal of the primary tumour and associated lymphadenectomy. Access to the abdomen is achieved through either a muscle-cutting transverse or midline abdominal incision. The procedure emphasizes meticulous dissection and removal of the tumour-containing area, with careful attention to preserving vital structures such as the ureters and pelvic autonomic nerves to minimize postoperative complications. Extensive lymphadenectomy, including first and second echelon nodal groups, and in selected cases, third echelon nodes such as lower paraaortic nodes, is performed. Conclusion: TMMR offers several advantages, including precise identification and preservation of vital structures, thorough lymphadenectomy, and favourable oncological outcomes with improved survival rates. Importantly, TMMR allows for the avoidance of radiation therapy in the majority of operable cervical cancer cases. In conclusion, TMMR represents a cornerstone in the surgical management of cervical cancer, striking a balance between oncological efficacy, radiation avoidance, and preservation of patients' quality of life.
