Abstract
The clinical effect of laparoscopic rectal cancer curative excision with pelvic autonomic nerve preservation (PANP) was investigated. This study evaluated the frequency of urinary and sexual dysfunction of 149 male patients with middle and low rectal cancer who underwent laparoscopic or open total mesorectal excision with pelvic autonomic nerve preservation (PANP) from March 2011 to March 2013. Eighty-four patients were subjected to laparoscopic surgery, and 65 to open surgery respectively. The patients were followed up for 12 months, interviewed, and administered a standardized questionnaire about postoperative functional outcomes and quality of life. In the laparoscopic group, 13 patients (18.37%) presented transitory postoperative urinary dysfunction, and were medically treated. So did 12 patients (21.82%) in open group. Sexual desire was maintained by 52.86%, un-ability to engage in intercourse by 47.15%, and un-ability to achieve orgasm and ejaculation by 34.29% of the patients in the laparoscopic group. Sexual desire was maintained by 56.36%, un-ability to engage in intercourse by 43.63%, and un-ability to achieve orgasm and ejaculation by 33.73% of the patients in the open group. No significant differences in urinary and sexual dysfunction between the laparoscopic and open rectal resection groups were observed (P>0.05). It was concluded that laparoscopic rectal cancer radical excision with PANP did not aggravate or improve sexual and urinary dysfunction.

Abstract
Lymph node metastasis informs prognosis and is a key factor in deciding further management, particularly adjuvant chemotherapy. It is core to all contemporary staging systems, including the widely used tumor node metastasis staging system. Patients with node-negative disease have 5-year survival rates of 70%-80%, implying a significant minority of patients with occult lymph node metastases will succumb to disease recurrence. Enhanced staging techniques may help to identify this subset of patients, who might benefit from further treatment. Obtaining adequate numbers of lymph nodes is essential for accurate staging. Lymph node yields are affected by numerous factors, many inherent to the patient and the tumour, but others related to surgical and histopathological practice. Good lymph node recovery relies on close collaboration between surgeon and pathologist. The optimal extent of surgical resection remains a subject of debate. Extended lymphadenectomy, extra-mesenteric lymph node dissection, high arterial ligation and complete mesocolic excision are amongst the surgical techniques with plausible oncological bases, but which are not supported by the highest levels of evidence. With further development and refinement, intra-operative lymphatic mapping and sentinel lymph node biopsy may provide a guide to the optimum extent of lymphadenectomy, but in its present form, it is beset by false negatives, skip lesions and failures to identify a sentinel node. Once resected, histopathological assessment of the surgical specimen can be improved by thorough dissection techniques, step-sectioning of tissue blocks and immunohistochemistry. More recently, molecular methods have been employed. In this review, we consider the numerous factors that affect lymph node yields, including the impact of the surgical and histopathological techniques. Potential future strategies, including the use of evolving technologies, are also discussed.

Abstract
While the oncological outcome of patients with rectal cancer has been considerably improved within the last decades, anorectal, urinary and sexual functions remained impaired at high levels, regardless of whether radical surgery was performed open or laparoscopically. Consequently, intraoperative monitoring of the autonomic pelvic nerves with simultaneous electromyography of the internal anal sphincter and manometry of the urinary bladder has been introduced to advance nerve-sparing surgery and to improve functional outcome. Initial results suggested that pelvic neuromonitoring may result in better functional outcomes. Very recently, it has also been demonstrated that minimally invasive neuromonitoring is technically feasible. Because, to the best of our knowledge, pelvic neuromonitoring has not been performed during robotic surgery, we report the first case of robotic-assisted low anterior rectal resection combined with intraoperative monitoring of the autonomic pelvic nerves.

Abstract
INTRODUCTION In the pelvis, the rectogenital septum (RGS) separates the urogenital compartment from the digestive compartment. In men, it corresponds to Denonvilliers' rectoprostatic fascia or rectovesical septum (RVS). Its purpose-and, indeed, its existence-are controversial in women. The purpose of this review was to update knowledge about the RGS in women and, in particular, to clarify its relationship to pelvic nerves in order to deduce practical consequences of pelvic surgery and compare it to the RVS in men. METHODS A review of the anatomical and surgical literature was undertaken. Evidence for embryological origin, composition, and surgical importance of the RGS in women and men is suggested. RESULTS This manuscript presents evidence of the existence of the RGS in both women (rectovaginal septum, RVaS) and men (rectovesical septum, RVS). It originates from the genital structures and extends from the rectogenital pouch to the perineal body. It is composed of connective tissue associated with bundles of smooth muscle cells and has lateral expansions in close contact with neurovascular bundles originating from the inferior hypogastric plexus. During pelvic surgery for carcinoma, preservation of nerve fibers of erectile bodies is necessary if possible. The RGS is thus an important surgical landmark during urogenital sinus surgery, prolapse surgery, and proctectomy in women as well as during proctectomy and prostatectomy in men. CONCLUSIONS The RGS is present in women as well as in men, with great similarities between the two sexes. It represents an important surgical landmark during pelvic nerve-sparing surgery.

Abstract
A significant part of rectal cancer survivors will experience urogenital dysfunction induced by the treatment. Significant progress has been made in order to improve the total mesorectal technique through different approaches (open, laparoscopic, robotic, transanal). Rectal cancer surgery is technically difficult notably deep in the pelvis, and therefore the most frequent cause of the postoperative dysfunction is the surgical nerve damage of the autonomic nerves at this level. The main objectives of these efforts were to obtain maximal oncological results and to achieve better functional outcomes including less postoperative urogenital dysfunctions. Our purpose was to build a comprehensive review of the existing literature data regarding this issue from past to present.

Abstract
BackgroundThe impact on quality of life attributed to treatment for rectal cancer remains high. Deterioration of the urinary function is a relevant complication within that context.ObjectiveTo detect the presence of urinary dysfunction and its risk factors among individuals underwent surgical treatment for rectal cancer.MethodsThe present prospective study analyzed 42 patients from both genders underwent surgical treatment for rectal adenocarcinoma with curative intent. The version of the International Prostatic Symptom Score (IPSS) questionnaire validated for the Portuguese language was applied at two time-points: immediately before and 6 months after surgery. Risk factors for urinary dysfunction were analysed by means of logistic regression and Student’s t-test.ResultsEight (19%) participants exhibited moderate-to-severe urinary dysfunction 6 months after surgery; the average IPSS increased from 1.43 at baseline to 4.62 six months after surgery (P<0.001). None of the variables assessed as potential risk factors exhibited statistical significance, i.e., age, gender, distance from tumour to anal margin, neoadjuvant therapy, adjuvant therapy, type of surgery, surgical approach (laparoscopy or laparotomy), and duration of surgery.ConclusionThis study identified an incidence of 19% of moderate to severe urinary dysfuction after 6 months surveillance. No risk factor for urinary dysfunction was identified in this population.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2015; 41:738-45.

Abstract
BACKGROUND Excellent anatomical knowledge of the rectum and surrounding structures is essential for total mesorectal excision (TME). Denonviliers' fascia (DVF) has been frequently studied, though the optimal anterior plane in TME is still disputed. The relationship of the lateral edges of DVF to the autonomic nerves and mesorectal fascia is unclear. We studied whole mout microscopic sections of en-bloc cadaveric pelvic exenteration and describe implications for TME. METHODS Four donated human adult cadaveric specimens (two males, two females) were obtained from the Leeds GIFT Research Tissue Programme. Paraffin-embedded mega blocks were produced and serially sectioned at 50 and 250 μm intervals. Sections were stained with haematoxylin & eosin, Masson's trichrome and Millers' elastin. Additionally, a series of eleven human fetal specimens (embryonic age of 9-20 weeks) were studied. RESULTS DVF consisted of multiple fascial condensations of collagen and smooth muscle fibres and was indistinguishable from the anterior mesorectal fascia and the prostatic fascia or posterior vaginal wall. The lateral edges of DVF appeared fan-shaped and the most posterior part was continuous with the mesorectal fascia. Fasciae were not identified in fetal specimens. CONCLUSION DVF is adherent to and continuous with the mesorectal fascia. Optimal surgical dissection during TME should be carried out anterior to DVF to ensure radical removal, particularly for anterior tumours. Autonomic nerves are at risk, but can be preserved by closely following the mesorectal fascia along the anterolateral mesorectum. The lack of evident fasciae in fetal specimens suggested that these might be formed in later developmental stages.

Abstract
AIM To take a deeper insight into the relationship between the root of the inferior mesenteric artery (IMA) and the autonomic nerve plexuses around it by cadaveric anatomy and explore anatomical evidence of autonomic nerve preservation in high ligation of the IMA in laparoscopic surgery for colorectal cancer. METHODS Anatomical dissection was performed on 11 formalin-fixed cadavers and 12 fresh cadavers. Anatomical evidence-based autonomic nerve preservation in high ligation of the IMA was performed in 22 laparoscopic curative resections of colorectal cancer. RESULTS As the upward continuation of the presacral nerves, the bilateral trunks of SHP had close but different relationships with the root of the IMA. The right trunk of SHP ran relatively far away from the root of IMA. When the apical lymph nodes were dissected close to the root of the IMA along the fascia space in front of the anterior renal fascia, the right trunk of SHP could be kept in suit under the anterior renal fascia. The left descending branches to SHP constituted a natural and constant anatomical landmark of the relationship between the root of IMA and the left autonomic nerves. Proximal to this, the left autonomic nerves surrounded the root of the IMA. Distally, the left trunk of the SHP departed from the root of IMA under the anterior renal fascia. When high ligation of the IMA was performed distal to it, the left trunk of SHP could be preserved. The distance between the left descending branches to SHP and the origin of IMA varied widely from 1.3 cm to 2.3 cm. CONCLUSIONS The divergences of the bilateral autonomic nerve preservation around the root of the IMA may contribute to provide anatomical evidence for more precise evaluation of the optimal position of high ligation of the IMA in the future.

Abstract
INTRODUCTION Genito-urinary disorders (GUD) for radical rectal cancer surgery range from 10 to 30%. In this study, primary endpoint is to prospectively assess their incidence in patients undergoing Laparoscopic Total Mesorectal Excision (LTME) without neoadjuvant chemo-radiation (NCR). Secondary endpoint is to detect the potential lesion site evaluating video-recordings of surgery. PATIENTS AND METHODS A study of 35 consecutive patients treated by LTME for extra-peritoneal rectal cancer not subjected to NCR, M:F = 23:12, median age 70, was evaluated preoperatively by Uroflowmetry and US postvoid residual urine measurement (PVR), International Prostatic Symptoms Score (IPSS), and International Consultation on Incontinence Modular Questionnaire (ICIQ) at 1 and 9 months post-operatively. Evaluation of sexual function was carried out by International Index of Erectile Function (IIEF) in males. Data were analyzed performing Fisher and paired samples t tests. Surgical videos of patients affected by GUD were reviewed to identify lesion sites. RESULTS Urinary function:IPSS average score: baseline 6.03 ± 5.51, 8.93 ± 6.42 (p = .005) at 1 month, and 7.26 ± 5.55 (p = .041) at 9 months. ICIQ baseline 2.67 ± 5.42, 4.27 ± 6.19 (p = NS) at 1 month, and 3.63 ± 5.23 (p = NS) at 9 months. Maximum urine flow rate baseline 15.95 ± 4.78 ml/s, 14.23 ± 5.27 after 1 month (p = .041), and 15.22 ± 4.01 after 9 months (p = NS). Mean urine flow rate baseline 9.15 ± 2.96 ml/s, 7.99 ± 4.12 ml/s at 1 month (p = .044), and 8.54 ± 4.19 ml/s at 9 months (p = NS). PVR baseline 59.62 ± 54.49, 64.59 ± 58.71 (p = NS) at 1 month, and 68.82 ± 77.72 (p = NS) at 9 months. Sexual function: IIEF baseline 19.38 ± 6.25, 14.06 ± 8.65 at 1 month (p = .011), and 15.4 ± 8.41 at 9 months, (p = NS). Video review of patients with disorders showed potential damage at the site of ligation of IMA (high hypogastric plexus) in 1 case, lateral and posterior mesorectum dissection (hypogastric nerves) in 2 cases, anterior dissection of the Denonvilliers fascia from seminal vesicles in 2 cases. CONCLUSIONS GUD at 1 month from LTME for rectal cancer are significant but improve at 9 months. Surgical video review of patients with GUD provides an important tool for detection of lesion sites.

Abstract
AIM This publication will describe our own experience of using the ERBEJET2(®) water-jet dissector during surgical interventions for rectal cancer. METHOD We utilized the water-jet dissection technique to obtain tissue specimens in 10 patients with rectal cancer. All patients thus underwent nerve-sparing low anterior resection of the rectum along with para-aortic lymphadenectomy. No intraoperative complications were registered. The postoperative period went uncomplicated in all patients. No dysuria was observed. Obtained tissue specimens were examined morphologically. Macroscopic examination included assessments of the preservation of the rectal fascia propria and the amount of cellular tissue along the anterior, posterior, and lateral surfaces of the rectum. We performed microscopy of the circumferential resection margin to characterize the surgical clearance and the intensity and depth of damage to the mesorectal tissue. On morphological examination, the quality of mesorectal excision was found to be good (Grade 3) in all 10 patients. RESULTS As the results of our study demonstrate, the depth of lateral tissue damage is minimal with the water-jet dissector. CONCLUSION Water-jet dissectors have their own place in the long list of armamentarium used in surgical interventions performed for rectal cancer and contribute to improving oncological and functional outcomes of surgical treatment in this patient population.

Abstract
AIM Genito-urinary complications are frequent after rectal surgery and are often due to nerve damage. The relationship between the pelvic nerves and surgical planes are unclear. The aim of the study was to determine the relationship between the inferior hypogastric plexus and the fascia of the lateral pelvic wall and between Denonvilliers' fascia and the efferent branches of the inferior hypogastric plexus. METHOD Computer-assisted anatomical dissection was used. Serial histological sections were made from six human foetuses and a male adult. Sections were stained with haematoxylin and eosin, Masson's trichrome and immunostainings. The sections were then digitalized and reconstructed in three dimensions. RESULTS The inferior hypogastric plexus was situated in a virtual space between the fascia propria of the rectum and the fascia on the upper surface of the levator ani. During the lateral dissection, the optimal surgical plane is the plane of the fascia propria of the rectum. We located Denonvilliers' fascia in three dimensions. It plays the role of a protective sheet for the neurovascular bundle. The optimal plane for nerve preservation is situated behind Denonvilliers' fascia. CONCLUSION This study has enabled a clear visualization of the optimal planes to perform total mesorectal excision while ensuring nerve preservation. Three-dimensional visualization clearly helps to bridge the gap between histological examination and the findings of surgery.

Abstract
SUMMARY Over the last few decades we have observed important advances in diagnostic imaging, surgery, pathology and multimodal treatments for rectal cancer, as well as increased efforts to reduce treatment-related toxicities and preserve quality of life for curatively treated patients. Neoadjuvant short-course radiotherapy and long-course chemoradiotherapy followed by total mesorectal excision remain widely accepted as the standard of care for patients with locally advanced rectal cancer. However, a carefully selected group of patients achieving a complete response to neoadjuvant chemoradiotherapy may be spared the effects of surgery and achieve satisfactory oncologic outcomes with a ‘wait-and-see’ strategy. Although supported by the results of previous studies, this intriguing paradigm shift needs prospective evaluation within a clinical trial setting and a more accurate prediction and assessment of response by means of tumor biomarkers and diagnostic imaging.

A prospective study of early removal of the urethral catheter after colorectal surgery in patients having epidural analgesia as part of the Enhanced Recovery After Surgery programme. Colorectal Dis 2013; 15:733-6.

Abstract
AIM Early removal of the urethral catheters is part of the enhanced postoperative recovery programme (ERAS). The effect of epidural anaesthesia on urinary retention was investigated in patients after colorectal resection. METHOD A prospective cohort study of all patients having colorectal surgery within an ERAS programme that included insertion of an epidural catheter over the last 5 years. RESULTS Two-hundred and ten patients had an epidural and a urethral catheter postoperatively. The duration of catheterization was not recorded in one patient who was therefore excluded from the study. One-hundred and eighteen patients had a trial without catheter (TWOC) prior to stopping the epidural (early TWOC). Ninety-one patients had TWOC after the epidural was stopped (late TWOC). Sixteen (7.6%) patients went into urinary retention (14 early TWOC and two late TWOC). The rate of urinary retention in the early TWOC group was significantly higher than that in the late TWOC group (11.9% vs 2.2%; χ(2), P = 0.009). Those who underwent a laparoscopic resection were significantly more likely to have undergone an early TWOC (χ(2), P = 0.001); however, there was no difference in retention rates between open and laparoscopic surgery (χ(2), P = 0.402). Pelvic surgery was not significantly associated with an increased risk of postoperative urinary retention (χ(2), P = 0.627). Male sex was not significantly associated with urinary retention (χ(2), P = 0.087). In the early TWOC group 86% had the catheter removed within 24 hours of surgery. CONCLUSION Early TWOC with epidural analgesia running significantly increases the risk of urinary retention; however, it was still successful in 88% of patients.

Quality of life of patients after low anterior, intersphincteric, and abdominoperineal resection for rectal cancer--a matched-pair analysis. Int J Colorectal Dis 2013; 28:679-88. [PMID: 23571868 DOI: 10.1007/s00384-013-1683-z] [Citation(s) in RCA: 67] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/18/2013] [Indexed: 02/04/2023]
Abstract
PURPOSE Limits for sphincter preservation in rectal cancer have been expanded under the assumption that patients with a permanent colostomy have worse quality of life (QoL). Incontinence and painful defecation are common problems; therefore, this study compares functional outcome and QoL after sphincter-sparing intersphincteric resection (ISR), low anterior resection (LAR), and abdominoperineal resection (APR) for rectal cancer. METHODS From a prospective database, three matched groups of patients after surgery for rectal cancer between 1999 and 2009 were extracted. Median follow-up was 59 months. Of 131 patients receiving a questionnaire, 95 % could be analyzed further. Generic and disease-specific validated QoL (European Organization for Research and Treatment in Cancer QLQ-C30, CR38) and Wexner incontinence score were used. RESULTS Global QoL was comparable between the groups. Physical functioning was significantly better after sphincter preservation surgery than APR (p < 0.05). Symptom scores for diarrhea (DIA) and constipation (CON) were higher after sphincter-preserving surgery (ISR: DIA 45.4, CON 20.2; LAR: DIA 34.1, CON 25.2) compared to APR (DIA 16.6, CON 12.0) (p < 0.05 and <0.01, respectively). Disease-specific QoL assessment showed significantly worse QoL regarding to male sexual function after APR (80.8) than after ISR (53.6) (p < 0.005). Regarding defecation, the ISR group showed significantly higher symptom scores than patients after LAR (p < 0.05). Wexner scores were significantly higher after ISR (12.9) than after LAR (9.5) (p < 0.005).

A pilot study of natural orifice transanal endoscopic total mesorectal excision with laparoscopic assistance for rectal cancer. Surg Endosc 2013; 27:3396-405. [PMID: 23572214 DOI: 10.1007/s00464-013-2922-7] [Citation(s) in RCA: 84] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2012] [Accepted: 03/03/2013] [Indexed: 12/23/2022]
Abstract
BACKGROUND The objective of this pilot study was to evaluate the feasibility and safety of natural orifice endoscopic transanal total mesorectal excision (TME) with laparoscopic assistance in a cohort study of five patients with stage I and IIA rectal cancer. METHODS Five eligible patients with node-negative rectal cancer located 4-12 cm from the anal verge were enrolled in an IRB-approved pilot study. All patients underwent transanal endoscopic TME with laparoscopic assistance, hand-sewn coloanal anastomosis, and a diverting loop ileostomy. Primary and secondary end points included adequacy of the mesorectal excision and 30-day postoperative complications, respectively. RESULTS Between November 2011 and May 2012, three males and two females underwent transanal endoscopic TME with laparoscopic assistance. Patient mean age and BMI were 48.6 ± 9.8 years and 25.7 ± 2.3 kg/m(2), respectively. Tumors were located an average of 5.7 ± 2.4 cm from the anal verge and preoperatively staged as T1N0M0 (2), T2N0M0 (1), and T3N0M0 (2). Mean operative time was 274.6 ± 85.4 min with no intraoperative complications. Partial intersphincteric resection was performed in conjunction with transanal endoscopic TME in three patients. Pathologic examination of TME specimens demonstrated complete mesorectal excision in all cases with negative proximal, distal, and radial margins. Mean length of hospital stay was 5.2 ± 2.6 days and three minor complications occurred, including one ileus and two cases of transient urinary dysfunction. At a mean early follow-up of 5.4 ± 2.3 months, all patients remain disease-free. CONCLUSIONS In this pilot study of five patients with rectal cancer, transanal endoscopic TME with laparoscopic assistance is feasible and safe, and is a promising alternative to open and laparoscopic TME. Evaluation of long-term functional and oncologic outcomes of this approach is needed before widespread adoption can be recommended.

Abstract
BACKGROUND Prophylactic surgery is still considered the standard treatment for patients with Familial Adenomatous Polyposis (FAP). Laparoscopic (Lap) surgery has been introduced as an alternative approach. The aim was to evaluate the feasibility and short- to long-term outcomes after prophylactic FAP surgery in adolescent. PROCEDURES A retrospective review of a database of adolescent patients with FAP identified through the Hereditary Colorectal Tumor Registry in a single Institution between 2005 and 2011. Patients underwent Lap total colectomy (TC) with ileo-rectal anastomosis (IRA) or proctocolectomy (PC) with ileal-pouch anal anastomosis (IPAA). The main outcomes were: Hospital stay, postoperative complications, desmoid tumor rates, tumor recurrence, long-term complications. RESULTS Sixteen consecutive patients with median age 16 (range 13-19) and median BMI 22 (17-29) underwent surgery. [correction made here after initial online publication]. Of them 14 patients had LAP TC with IRA and 2 had PC with IPAA. Operative time (median, range) was TC/IRA 270 (210-330) minutes; PC/IPAA 370 (360-380) minutes. Length of extraction site was cm (median, range) 6(5-8). Lymph Node harvest (median, range) 81 (32-139). Postoperative stay days (median, range) were 6 (4-24). Five patients (31.2%) showed dysplasia on the pathological report and 3 of them showed severe dysplasia. Median follow-up time (FU) was 39 months, range (10-82). The anastomotic leak rate for 30 days was 2 (12.5%). Pouch failure was 0. Post-surgical desmoid tumors rate was 1 (6.2%) and there was no tumor recurrence. Anastomotic stricture, SBO and mortality were zero. CONCLUSIONS Lap approach is feasible and shows acceptable postoperative outcomes. Lap surgery can be an appealing alternative for prophylactic surgery in adolescent FAP patients. Pediatr Blood Cancer 2012; 59: 1223-1228. © 2012 Wiley Periodicals, Inc.

Abstract
Nowadays left colon and rectal cancer treatment has been well standardized in both open and laparoscopy. Nevertheless, the level of the ligation of the inferior mesenteric artery (IMA), at the origin from the aorta (high tie) or below the origin of the left colic artery (low tie), is still debated. The objective of the systematic review is to evaluate the current scientific evidence of high versus low tie of the IMA in colorectal cancer surgery. The outcomes considered were overall 30-days postoperative morbidity, overall 30-days postoperative mortality, anastomotic leakage, 5-years survival rate, and overall recurrence rate. A total of 8.666 patients were included in our analysis, 4.281 forming the group undergoing high tie versus 4.385 patients undergoing low tie. Neither the high tie nor the low tie strategy showed an evidence based success, as no statistically significant differences were identified for all outcomes measured. Future high powered and well designed randomized clinical trials are needed to draw definitive conclusion on this dilemma.

Abstract
PURPOSE To confront nerve dissection, tissue staining, nerve immunolabelling and Computer-Assisted Anatomic Dissection (CAAD) in identifying the precise location and origin of intrapelvic autonomic nerve fibers and to provide a three-dimensional (3D) representation of their relationship to other anatomical structures. METHODS Serial transverse sections of the pelvic portion of five human female fetuses (18-31 weeks of gestation) were studied histologically (with hematoxylin/eosin and Masson trichrome) and immunohistochemically (anti-protein S100 antibody) digitized and reconstructed three-dimensionally with Surf driver software for Windows (Winsurf 4.3). Three fresh female adult cadavers were macroscopically dissected to individualize the inferior hypogastric plexus afferences and efferences and their anatomical relationships. RESULTS This combined investigation including the CAAD technique allowed identifying the precise location and distribution of the pelvic nerve elements and their relationships to female pelvic organs. Hypogastric nerves (HN) were located in the retrorectal multilaminar structure and joined the homolateral inferior hypogastric plexus (IHP) at the lateral border of the recto-uterine pouch. The intersection of the ureter with the posterior wall of the uterine artery precisely located the junction of HN and IHP. Antero-inferior branches supplying female sexual and continence organs originated from the antero-inferior angle of IHP and were bundled at the posterolateral vaginal wall. CONCLUSIONS CAAD is an encouraging anatomical method for the development of anatomical and surgical research and teaching. Complementary to traditional anatomical studies, it may provide useful anatomical data for the comprehension of postoperative sexual and urinary dysfunction and the development of nerve-sparing surgical techniques.
