Abstract The Denonvilliers’ fascia (DVF) plays an important role in rectal surgery because of its anatomic position and its relationship to the surrounding organs. It affects the surgical plane anterior to the rectum in the procedure of total mesorectal excision (TME). Anatomical and embryological studies have helped us to understand this structure to some extent, but many controversies remain. In terms of its embryonical origin, there are three mainstream hypotheses: peritoneal fusion of the embryonic cul-de-sac, condensation of embryonic mesenchyme, and mechanical pressure. Regarding its architecture, the DVF may be a single, two, or multiple layers, or a composite single-layer structure. In women, most authors deem that this structure does exist but they are willing to call it the rectovaginal septum rather than the DVF. Operating behind the DVF is supported by most surgeons. This article will review those mainstream studies and opinions on the DVF and combine them with what we have observed during surgery to discuss those controversies and consensuses mentioned above. We hope this review may help young colorectal surgeons to have a better understanding of the DVF and provide a platform from which to guide future scientific research.

Pelvic Autonomic Nerves

AbstractTransanal total mesorectal excision (taTME) has evolved over the past decade fueled by advances in minimally invasive surgery. The technique aims to overcome the constraints posed by a narrow rigid pelvis and poor TME visualization that are encountered during “top-down” rectal surgery. A more accurate pelvic dissection should subsequently result in safer oncological resections and better preservation of pelvic autonomic nerves. taTME is an advanced complex technique that requires dedicated training and experience in TME surgery. Initial results from small cohorts are promising and confirmation by randomized controlled trials is eagerly awaited.

The Mean

Introduction. Single-access laparoscopic surgery (SALS) has been successfully introduced for colectomy surgery; however, for mid to low rectum procedures such as total mesorectal excision, it can be technically complicated. In this study, we introduced a single-access technique for rectum cancer operations without the use of other instruments.Aims. To show the short-term results of single-access laparoscopic rectal surgery in terms of pathologic results and immediate complications.Settings and Design. Prospective study.Materials and Methods. We selected middle rectum to anal canal cancer patients to undergo single-access laparoscopic rectal resection for rectal cancer. All patients had total mesorectal excisions. An umbilical incision was made for the insertion of a single multichannel port, and a mesocolic window was created to identify the inferior mesenteric artery and vein. Total mesorectal excision was performed. There were no perioperative complications. The mean operative time was 269 minutes; the median hospital stay was 7 days; the mean wound size was 5.5 cm; the median number of harvested lymph nodes was 15; and all patients had intact mesorectal capsules.Statistical Analysis Used. Mean, minimum–maximum.Conclusion. Single-access laparoscopic surgery for rectal cancer is feasible while oncologic principles and patient safety are maintained.

Laparoscopic Tme

AbstractThe curative treatment of locally advanced rectal cancer is currently based on chemoradiotherapy and total mesorectal excision (TME). Laparoscopy has developed considerably because of obvious clinical benefits such as reduced pain and shorter hospital stay. Recently, several prospective randomized clinical trials with long-term follow-up have showed that laparoscopy is noninferior to laparotomy with the same oncologic outcomes in terms of survival and local control rate. However, laparoscopic TME remains a challenging procedure requiring a high level of expertise and a long learning curve to ensure an adequate and safe resection. The only relative contraindication of laparoscopic rectal surgery is T4 rectal cancer extended beyond the plane of TME. In this situation, it is reasonable to consider an open resection to avoid an uncomplete resection. In obese and elderly patients, laparoscopic TME also provides the same benefits as in nonobese and younger patients but may be more difficult to achieve. This review summarizes current knowledge on the place of laparoscopic TME in the treatment of rectal cancer.

Contexte : L’exérèse totale du mésorectum par voie transanale (TaTME) pour la prise en charge du cancer du rectum est récemment apparue comme alternative à l’exérèse totale du mésorectum par voie abdominale. Cependant, certaines inquiétudes à propos des résultats oncologiques de cette technique chirurgicale ont émergé. Le but de cette étude était d’évaluer le taux de récidives locales après TaTME. Les objectifs secondaires s’intéressaient à la mortalité postopératoire, au taux de fistule anastomotique et au taux de stomie définitive. Méthodes : Les données de tous les patients opérés par TaTME ont été rapportées et comparées aux données issues des registres nationaux norvégiens de cancers colorectaux (NCCR) et de chirurgie gastro-intestinale (NoRGast). Les taux de récidive locale étaient estimés selon Kaplan-Meier. Résultats : En Norvège, 157 patients ont été opérés par TaTME pour un cancer du rectum entre octobre 2014 et octobre 2018. Trois des sept centres hospitaliers participants ont abandonné la réalisation de cette intervention après cinq procédures. Le taux de récidive locale était de 12 sur 157 patients (7,6 %) ; huit récidives locales étaient multifocales ou étendues. Le taux de récidive locale après un suivi de à 2,4 ans était estimé à 11,6 % (IC 95 % : [6,6‒19,9]) après TaTME contre 2,4 % (IC 95 % : [1,4‒4,4]) dans le registre NCCR (p < 0,001). Le hasard ratio était estimé à 6,71 (IC 95 % : [2,94‒15,32]). Le taux de fistule anastomotique nécessitant une réintervention était de 8,4 % dans le groupe TaTME contre 4,5 % dans le registre NoRGast (p = 0,047). Cinquante-six patients (35,7 %) étaient porteurs d’une stomie à la fin du suivi, dont 39 (24,8 %) étaient définitives. Conclusion : Le taux de fistule anastomotique était plus élevé après TaTME en comparaison aux données des registres nationaux norvégiens. Le taux de récidive locale ainsi que les caractéristiques de cette récidive après TaTME étaient défavorables.
