For patients with rectal cancer, with tumors very close to the anal sphincter or involving these structures, amputation abdominoperineal of the rectum continues being the main treatment.

The aim of this study to evaluate the surgical complications and the quality of life of patients who underwent the abdominoperineal amputation of the rectum and either had an abdominal colostomy or a perineal colostomy and self-irrigation through a new method of irrigation and evaluate the effectiveness of this new method. After official approval from the Ethics Committee in Research of the Cancer Hospital of Barretos, Brazil, a cross-sectional study with prospective data collection of 38 patients was carried out from June 2009 to November 2009. The quality of life was evaluated through two questionnaires developed by the European Organization for Research and Treatment of Cancer (EORTC): one was specific for cancer (EORTC QLQ-C30) and the other one was specific for rectal cancer (EORTC QLQ-CR38). A total of 38 patients were included, 21 with perineal colostomy and 17 with abdominal colostomy. Regarding socio-demographic, clinical and therapeutic characteristics, the groups were similar in age, gender, race, marital status, education, income, occupation, clinical...

Introduction : Le système nerveux autonome (SNA) est en situation supralévatorienne, le système somatique en situation infra lévatorienne. Le sympathique assurerait les fonctions de sécrétion et le parasympahtique, les fonctions dʼérection. Le rectum est en rapport étroit avec ces éléments nerveux. La protectomie avec exérèse totale du mésorectum pour cancer est associée à des séquelles sexuelles par lésion iatrogène des nerfs pelviens.Objectifs : Étudier la physiologie et lʼanatomie topographique et structurelle de l'innervation pelvipérinéale Matériels et méthodes : Cinq pelvis de foetus et dix pelvis dʼadultes féminins ont été prélevés pour études macroscopiques, microscopiques etimmunohistochimiques des nerfs pelviens. Les coupes ont été colorées puis immunomarquées pour détecter les fibres nerveuses (PS-100), somatiques(PMP22), autonomes adrénergiques (TH), cholinergiques (VAChT), sensitives(CGRP) et les fibres pro-érectiles (nNOS). Les lames ont été numérisées et reconstruites en 3D.Résultats : Les fibres nerveuses du SNA, richement interconnectées,véhiculent de façon mixte lʼinflux sympathique et parasympathique.Celles issues du plexus hypogastrique inférieur contrôlant les fonctions sexuelles sont regroupées avec le pédicule vaginal long et forment la bandelette neuro-vasculaire (BNV) sur la face antérolatérale du rectum à « 2et 10h ». Cette BNV est en avant de lʼexpansion postérolatérale du septum recto vaginal (SRV) qui la protège et qui est lʼéquivalent chez lʼhomme du fascia de Denonvilliers. Cette BNV concentre lʼensemble des fibres nerveusespro-érectiles destinées au périnée. Une lésion tronculaire de cette bandelette pourrait conduire à un trouble de lʼérection clitoridienne et de la lubrification vulvaire car, à ce niveau, les efférences sympathiques et parasympathiques coexistent.Conclusion: Un modèle anatomo-physiologique et pédagogiquedʼinnervation pelvipérinéale féminine a été développé. Ces travaux offrent des perspectives dʼétudes cliniques afin de mieux évaluer les dysfonctions sexuelles postopératoires. / Introduction: The nerve supply of the autonomic nervous system (ANS) to the pelvis is located above the levator ani muscle, and the somatic nerve supply to the pelvis is situated below levator ani. Sympathetic innervation assures secretory functions and parasympathetic innervation allows erection. The rectum is anatomically closely associated with these nerves. Protectomy with total excision of the mesorectum for cancer is associated with sexual sequellae due to iatrogenic damage to the pelvic nerves.Objectives: To study the physiology and topographic and structural anatomy of the innervation of the pelvis.Materials and methods: Five fœtal pelvises and ten adult female pelvises were collected for macroscopic, microscopic, and immunohistochemical studies of pelvic nerves. Sections were stained and then immunostained to reveal nerve fibres (PS-100), somatic nerves (PMP22), adrenergic autonomic nerves (TH), cholinergic autonomic nerves (VAChT), sensory nerves (CGRP) and pro-erectile nerves (nNOS). Sections were numbered and reconstructed in 3D.Results: ANS nerve fibres, densely interconnected, carry a combination of sympathetic and parasympathetic fibres.Nerve fibres controlling sexual function from the inferior hypogastric plexus are clustered along the vaginal pedicle and form the neurovascular bundle (NVB) on the anterolateral face of the rectum between “2 and 10 o’clock”. This NVB is in front of the expansion of the rectovaginal septum (RVS) which protects it. In males, the equivalent structure is the rectoprostratic fascia. This NVB contains all of the pro-erectile nerves supplying the perineum. A truncal lesion to this bundle could result in erectile dysfunction of the clitoris as well as difficulties in vulvar lubrication because sympathetic and parasympathetic efferent fibres are both present at this site.Conclusion: An educational anatomical and physiological model of the innervation of the female pelvis and perineum has been developed. This work offers perspectives for clinical studies to facilitate better evaluation of cases of post-operative sexual dysfunction.
