Denonvilliers fascia is a dense structure between the rectum and the genitourinary system, and plays as a barrier. In recent years, along with in-depth study of TME, scholars have taken many discussions on Denonvilliers fascia structure and the dissection plane. On the one hand, some consensus have been made on Denonvilliers fascia structure, but still needs to further clarify its microstructure. On the other hand, scholars have generally recognized the neurovascular bundles are on Denonvilliers fascia sides. They should be protected during rectal surgery, however, the details should be clarified. Based on "Fascial Surgery" theory, this article describes Denonvilliers fascia structure and clinical application combined with previous research and our research results.

Urinary and sexual dysfunction after rectal cancer surgery: A surgical challenge.
World J Gastroenterol

Department of Surgery and Centre of Minimal Invasive Surgery, GFO Kliniken Bonn, Bonn 53225, North Rhine-Westphalia, Germany.
This manuscript focused on the surgical challenge of urinary and sexual dysfunction after rectal cancer surgery based on the interesting results demonstrated by the observational study of Chen , which was published in the . Urinary dysfunction occurs in one-third of patients treated for rectal cancer. Surgical nerve damage is the main cause of urinary dysfunction.

Performing robot-assisted radical prostatectomy for prostate cancer following previous rectal cancer surgery in cases involving anal-preserving surgeries such as low anterior resection or intersphincteric resection can be challenging because of the possibility of adhesions.
Case Presentation: A 74-year-old man who had undergone laparoscopic intersphincteric resection for rectal cancer was diagnosed with prostate cancer.

Article Synopsis
- The study aimed to analyze the circumferential fascia of the rectum to understand its anatomy and clinical significance, specifically using four cadaver specimens and 16 postoperative samples from rectal cancer patients.
- Key findings include the triangular structure of the mesorectum at the peritoneal reflection, the precise attachment points of Denonvilliers' fascia, and its relationship to surrounding structures like the seminal vesicles and prostate.
- The research highlighted the merging of the pre-hypogastric fascia with Denonvilliers' fascia and the formation of rectosacral fascia, contributing to our understanding of rectal innervation and surgical implications.
Tailoring rectal cancer surgery: Surgical approaches and anatomical insights during deep pelvic dissection for optimal outcomes in low-lying rectal cancer.
Ann Gastroenterol Surg

Colorectal Division, Department of Surgery, Yongin Severance Hospital Yonsei University College of Medicine Gyeonggi-do Korea.
This review article explores advanced surgical approaches and anatomical insights for tailoring rectal cancer surgery, particularly focusing on low-lying rectal cancer. With the evolution of imaging technologies, precise preoperative planning has become possible, enhancing the visualization of anatomy surrounding the rectum and enabling more accurate assessments of circumferential resection margin (CRM) involvement. The article emphasizes the dynamic nature of rectal cancer treatment, advocating for individualized surgical planning based on comprehensive preoperative imaging and intraoperative assessment.

Division of Colon and Rectal Surgery, Department of Surgery, Yonsei University College of Medicine, Seoul, Korea.
Article Synopsis
- Total mesorectal excision (TME) significantly enhances rectal cancer surgery by reducing recurrence rates and improving survival, focusing on the complete removal of the mesorectum along natural embryologic planes.
- Key anatomical structures involved in TME include the rectal proper fascia, Denonvilliers fascia, and pelvic autonomic nerves, with specific techniques aimed at preserving these structures and ensuring clear resection margins.
- Continuous advancements in surgical techniques, the adoption of minimally invasive approaches, and ongoing research in tumor biology are crucial for refining TME practices and improving patient outcomes in rectal cancer management.
