Abstract
The ability to experience pleasurable sexual activity is important for human health. Receptive anal intercourse (RAI) is a common, though frequently stigmatized, pleasurable sexual activity. Little is known about how diseases of the colon, rectum, and anus and their treatments affect RAI. Engaging in RAI with gastrointestinal disease can be difficult due to the unpredictability of symptoms and treatment-related toxic effects. Patients might experience sphincter hypertonicity, gastrointestinal symptom-specific anxiety, altered pelvic blood flow from structural disorders, decreased sensation from cancer-directed therapies or body image issues from stoma creation. These can result in problematic RAI - encompassing anodyspareunia (painful RAI), arousal dysfunction, orgasm dysfunction and decreased sexual desire. Therapeutic strategies for problematic RAI in patients living with gastrointestinal diseases and/or treatment-related dysfunction include pelvic floor muscle strengthening and stretching, psychological interventions, and restorative devices. Providing health-care professionals with a framework to discuss pleasurable RAI and diagnose problematic RAI can help improve patient outcomes. Normalizing RAI, affirming pleasure from RAI and acknowledging that the gastrointestinal system is involved in sexual pleasure, sexual function and sexual health will help transform the scientific paradigm of sexual health to one that is more just and equitable.

Long-term clinical outcomes after high and low ligations with lymph node dissection around the root of the inferior mesenteric artery in patients with rectal cancer. Ann Coloproctol 2024; 40:62-73. [PMID: 38414122 PMCID: PMC10915527 DOI: 10.3393/ac.2023.00094.0013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 04/25/2023] [Accepted: 04/30/2023] [Indexed: 02/29/2024] Open
Abstract
PURPOSE This study aimed to evaluate the long-term clinical outcomes based on the ligation level of the inferior mesenteric artery (IMA) in patients with rectal cancer. METHODS This was a retrospective analysis of a prospectively collected database that included all patients who underwent elective low anterior resection for rectal cancer between January 2013 and December 2019. The clinical outcomes included oncological outcomes, postoperative complications, and functional outcomes. The oncological outcomes included overall survival (OS) and relapse-free survival (RFS). The functional outcomes, including defecatory and urogenital functions, were analyzed using the Fecal Incontinence Severity Index, International Prostate Symptom Score, and International Index of Erectile Function questionnaires. RESULTS In total, 545 patients were included in the analysis. Of these, 244 patients underwent high ligation (HL), whereas 301 underwent low ligation (LL). The tumor size was larger in the HL group than in the LL group. The number of harvested lymph nodes (LNs) was higher in the HL group than in the LL group. There were no significant differences in complication rates and recurrence patterns between the groups. There were no significant differences in 5-year RFS and OS between the groups. Cox regression analysis revealed that the ligation level (HL vs. LL) was not a significant risk factor for oncological outcomes. Regarding functional outcomes, the LL group showed a significant recovery in defecatory function 1 year postoperatively compared with the HL group. CONCLUSION LL with LNs dissection around the root of the IMA might not affect the oncologic outcomes comparing to HL; however, it has minimal benefit for defecatory function.

Abstract
Within the intricate field of rectal cancer surgery, the contentious debate over the optimal level of ligation of the inferior mesenteric artery (IMA) persists as an ongoing discussion, influencing surgical approaches and patient outcomes. This narrative review incorporates historical perspectives, technical considerations, and functional as well as oncological outcomes, addressing key questions related to anastomotic leakage risks, genitourinary function, and oncological concerns, providing a more critical understanding of the well-known inconclusive evidence. Beyond the dichotomy of high versus low tie, it navigates the complexities of colorectal cancer surgery with a fresh perspective, posing a transformative question: "Is low tie ligation truly reproducible?" Considering a multidimensional approach that enhances patient outcomes by integrating the surgeon, patient, technique, and technology, instead of a rigid and categorical statement, we argued that a balanced response to this challenging question may require compromise.

Abstract
There is an ongoing unmet need of early identification and discussion regarding the sexual and urinary dysfunction in the peri-operative period to improve the quality of life (QoL), particularly in young rectal cancer survivors. Retrospective analysis of prospectively maintained database was done. Male patients less than 60 years who underwent nerve preserving, sphincter sparing rectal cancer surgery between January 2013 and December 2019, were screened. International Index of Erectile Function (IIEF-5) questionnaire was given to assess erectile dysfunction (ED). Patients were asked questions regarding their sexual and urinary function from the EORTC-QL CRC 38 questionnaire, and responses were recorded. Patients were also asked to report any retrograde ejaculation in post-operative period. Sixty-two patients were included in the study. Fifty-four patients (87.1%) received a diversion stoma. Sixteen patients (29.6%) felt stoma was interfering with their sexual function. Six patients (9.7%) reported retrograde ejaculation. Only 5 patients (8.06%) had moderate to severe ED, and the rest had none to mild ED. On univariate and multivariate analysis, only age predicted the development of clinically significant ED. Ten patients (16.1%) had significantly reduced sexual urges, and 23 patients (37.1%) had significant decrease in sexual satisfaction after surgery. Five patients (8.06%) reported having minor urinary complaints. No patient reported having major complaint pertaining to urinary health. While long-term urinary complaints are infrequent, almost half the patient suffered from erectile dysfunction in some form. There is a weak but significant association of age and ED. Follow-up clinic visits provide an ideal opportunity to counsel patients and provide any medical intervention, when necessary.

Abstract
PURPOSE Scarce research has reported the comparison between robotic and laparoscopic surgery in mid-low rectal cancer. Therefore, this meta-analysis is aimed to compare the safety and efficacy of the two surgical approaches. METHODS A comprehensive search of the databases (PubMed, EMBASE, Cochrane, and Web of Science) was performed for studies comparing robotic and laparoscopic surgery. The outcomes of interest acquired from eight articles included three aspects: intraoperative conditions, postoperative status of patients, and complications. All data (robotic = 1350 patients, laparoscopic = 1330 patients) enrolled were analyzed using Rev Man 5.4. RESULTS Compared to the laparoscopic group, the robotic group indicated a noticeable superiority in estimated blood loss (P < 0.0001), number of lymph nodes dissected (P = 0.004), time to first flatus (P = 0.001), time to first fluid diet (P = 0.001), hospital stay (P < 0.0001), conversion (P = 0.009), and urinary retention (P = 0.0006), but devoted much more operation time (P = 0.0004). CONCLUSION Robotic surgery was associated with superiority over laparoscopic surgery in increasing surgical safety, accelerating postoperative recovery, and reducing complications, which suggested that robotic surgery could be a safe and effective method for treating mid-low rectal cancer.

Abstract
The total mesorectal excision (TME) approach has been established as the gold standard for the surgical treatment of middle and lower rectal cancer. This approach is widely accepted to minimize the risk of local recurrence and increase the long-term survival rate of patients undergoing surgery. However, standardized TME causes urogenital dysfunction in more than half of patients, thus lowering the quality of life of patients. Of note, pelvic autonomic nerve damage during TME is the most pivotal cause of postoperative urogenital dysfunction. The anatomy of the Denonvilliers' fascia (DVF) and its application in surgery have been investigated both nationally and internationally. Nevertheless, controversy exists regarding the basic to clinical anatomy of DVF and its application in surgery. Currently, it is a hotspot of concern and research to improve the postoperative quality of life of patients with rectal cancer through the protection of their urinary and reproductive functions after radical resection. Herein, this study systematically describes the anatomy of DVF and its application in surgery, thus providing a reference for the selection of surgical treatment modalities and the enhancement of postoperative quality of life in patients with middle and low rectal cancer.

Abstract
BACKGROUND The preservation of autonomic nerves is the most important factor in maintaining genitourinary function in colorectal surgery; however, these nerves are not clearly recognisable, and their identification is strongly affected by the surgical ability. Therefore, this study aimed to develop a deep learning model for the semantic segmentation of autonomic nerves during laparoscopic colorectal surgery and to experimentally verify the model through intraoperative use and pathological examination. MATERIALS AND METHODS The annotation data set comprised videos of laparoscopic colorectal surgery. The images of the hypogastric nerve (HGN) and superior hypogastric plexus (SHP) were manually annotated under a surgeon's supervision. The Dice coefficient was used to quantify the model performance after five-fold cross-validation. The model was used in actual surgeries to compare the recognition timing of the model with that of surgeons, and pathological examination was performed to confirm whether the samples labelled by the model from the colorectal branches of the HGN and SHP were nerves. RESULTS The data set comprised 12 978 video frames of the HGN from 245 videos and 5198 frames of the SHP from 44 videos. The mean (±SD) Dice coefficients of the HGN and SHP were 0.56 (±0.03) and 0.49 (±0.07), respectively. The proposed model was used in 12 surgeries, and it recognised the right HGN earlier than the surgeons did in 50.0% of the cases, the left HGN earlier in 41.7% of the cases and the SHP earlier in 50.0% of the cases. Pathological examination confirmed that all 11 samples were nerve tissue. CONCLUSION An approach for the deep-learning-based semantic segmentation of autonomic nerves was developed and experimentally validated. This model may facilitate intraoperative recognition during laparoscopic colorectal surgery.

Abstract
BACKGROUND Surgically induced nerve damage is a common but debilitating side effect. By developing tracers that specifically target the most abundant protein in peripheral myelin, namely myelin protein zero (P0), we intend to support fluorescence-guided nerve-sparing surgery. To that end, we aimed to develop a dimeric tracer that shows a superior affinity for P0. METHODS Following truncation of homotypic P0 protein-based peptide sequences and fluorescence labeling, the lead compound Cy5-P0101-125 was selected. Using a bifunctional fluorescent dye, the dimeric Cy5-(P0101-125)2 was created. Assessment of the performance of the mono- and bi-labeled compounds was based on (photo)physical evaluation. This was followed by in vitro assessment in P0 expressing Schwannoma cell cultures by means of fluorescence confocal imaging (specificity, location of binding) and flow cytometry (binding affinity; KD). RESULTS Dimerization resulted in a 1.5-fold increase in affinity compared to the mono-labeled counterpart (70.3 +/- 10.0 nM vs. 104.9 +/- 16.7 nM; p = 0.003) which resulted in a 4-fold increase in staining efficiency in P0 expressing Schwannoma cells. Presence of two targeting vectors also improves a pharmacokinetics of labeled compounds by lowering serum binding and optical stability by preventing dye stacking. CONCLUSIONS Dimerization of the nerve-targeting peptide P0101-125 proves a valid strategy to improve P0 targeting.

Abstract
OBJECTIVE The purpose of this study was to perform a meta-analysis comparing the oncological, intraoperative and safety outcomes in laparoscopic rectal cancer surgery with and without preservation of the left colic artery (LCA). METHOD We searched several databases including PubMed, Web of Science, Cochrane Library, and Embase databases. This meta-analysis included randomized clinical trials, prospective, and retrospective comparative studies regarding high- or modified low-tie ligation of the inferior mesenteric artery in laparoscopic rectal cancer surgery. RESULTS Of 641 potentially eligible articles, 16 studies with 3050 participants met the eligibility criteria and were included in the meta-analysis. There was no significant difference in estimated blood loss (WMD -2.63, 95% CI -5.69 to 0.43; P = .09), the number of harvested lymph nodes (WMD -0.35, 95% CI -1.60 to 0.20; P = .50), the number of apical lymph node yield (WMD -0.19, 95% CI -0.52 to 0.13; P = .24), the number of apical lymph node metastasis (OR 0.76, 95% CI 0.40 to 1.45; P = .40), rate of conversion to open surgery (OR 0.74, 95% CI 0.50 to 1.09; P = .513), rate of urinary dysfunction (OR 1.39, 95% CI 0.71 to 2.74; P = .34), rate of recurrence and metastasis (OR 1.10, 95% CI 0.75 to 1.61; P = .64), 5-year survival rate (OR 0.89, 95% CI 0.67 to 1.18; P = .42). However, this meta-analysis demonstrated a statistically significant difference in operating time (WMD -9.92, 95% CI -15.49 to -5.84; P = .0005), rate of diverting stom (OR 1.42, 95% CI 1.06 to 1.92; P = .02), rate of anastomotic leakage (OR 2.673, 95% CI 1.91 to 3.62; P < .00001), time to first flatus (WMD 0.29, 95% CI 0.11 to 0.48; P = .002), time of hospitalization (WMD 0.64, 95% CI 0.14 to 1.15; P = .01) between the 2 surgical techniques. COCLUSION The available evidence suggests that preserving the left colic artery is a safe, effective technique for patients with laparoscopic rectal cancer. nique for patients with laparoscopic rectal cancer.

Abstract
Background Tumors of the pre-sacral and sacral spaces are a rare occurrence in children. Total tumor excision is required due to the significant risk of relapse in the event of partial surgery, but the surgical procedure may lead to postoperative problems such as urinary, sexual, and anorectal dysfunctions. Intraoperative neuromonitoring (IONM) has gained popularity in recent years as a strategy for preventing the onset of neurologic impairments by combining several neurophysiological techniques. The aim of our study is to describe the experience of Bambino Gesù Children's Hospital in the use of IONM in pediatric pelvic surgery. Materials and Methods The data of patients treated for pelvic malignancies at Bambino Gesù Children's Hospital from 2015 to 2019 were retrospectively collected. All patients were assessed from a neurologic and neuro-urologic point of view at different time-points (before and immediately after surgery, after 6 months, and 1-year follow-up). They were all monitored during a surgical procedure using multimodal IONM including transcranial motor evoked potentials (TcMEP), triggered-EMG (t-EMG), pudendal somatosensory evoked potentials (PSSEP), and bulbocavernosus reflex (BCR). Results During the study period, ten children underwent pelvic tumor removal at our Institution. In all cases, intraoperative neurophysiological recordings were stable and feasible. The preservation of neurophysiological response at the same intensity during surgical procedures correlated with no new deficits for all neurophysiological techniques. Discussion Although the impact of the IONM on surgical strategies and clinical follow-up is unknown, this preliminary experience suggests that the appropriate use of several neurophysiological techniques can influence both the radicality of pelvic tumor removal and the neurological and urological outcome at clinical follow-up. Finally, because of the highly complex anatomy and inter-individual variances, this is especially useful in this type of surgery.

BMC Surg 2022; 22:185. [PMID: 35568823 PMCID: PMC9107708 DOI: 10.1186/s12893-022-01592-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Accepted: 04/06/2022] [Indexed: 11/28/2022] Open
Abstract
Background Urogenital dysfunction is recognized as a serious complication affecting patient quality of life after rectal cancer surgery to treat rectal cancer; however, the studies focus on the urogenital function after robot-assisted rectal cancer surgery compared to laparoscopic surgery are limited. Methods Male patients undergoing robotic total mesorectal excision (R-TME) or laparoscopic total mesorectal excision (L-TME) were prospectively enrolled. The International Prostate Symptom Score (IPSS) and the five-item version of the International Index of Erectile Function (IIEF-5) scale were used to compare the urogenital function of the two groups preoperatively and 3, 6, and 12 months postoperatively. Results Eighty-nine patients who planned to undergo R-TME and L-TME were prospectively enrolled; 77 patients of these patients (86.5%) completed all questionnaires at all time points and were thus included in the final analysis. Of the included patients, 38 underwent R-TME and 39 underwent L-TME. There was no significant difference in age, BMI, American Society of Anesthesiologists (ASA) score, tumor location, neoadjuvant therapy, operation method, postoperative pathological results and adjuvant therapy between the two groups. Preoperative urogenital function was similar in both groups; however, the IPSS was significantly lower in R-TME patients than that in T-TME patients at 6 months and 12 months [(7.82 ± 2.25 vs. 9.95 ± 3.01, P = 0.006; 7.62 ± 2.5 vs. 9.12 ± 2.64, P = 0.012)]. IIEF-5 scores decreased 3 months after R-TME and L-TME surgery (14.87 ± 3.27 vs. 13.92 ± 3.62, p = 0.231) and then gradually increased; at 12 months, IIEF-5 scores were comparable to those at baseline in both groups. IIEF-5 scores were higher in R-TME patients than those in L-TME patients at 6 months (18.55 ± 3.45 vs. 16.75 ± 3.26, P = 0.021), but there was no significant difference between the two groups at 12 months (21.22 ± 3.06 vs. 19.95 ± 3.03, P = 0.071). Conclusions The robotic approach for TME was associated with more rapid restoration of male urogenital function than the laparoscopic approach.

Abstract
BACKGROUND This systematic review and meta-analysis studied the role of high (HL) versus low (LL) inferior mesenteric artery (IMA) ligation on genitourinary and defecatory dysfunction in patients who had undergone resection for rectal cancer (RC). METHODS A systematic literature search of four major databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Randomized controlled trials (RCTs) comparing HL and LL of IMA in RC surgery were identified. Those studies that looked at genitourinary or defecatory dysfunction were included. Random-effects modeling to summarize statistics was performed. The risk of bias was assessed using Cochrane's Risk-of-Bias tool 2. RESULTS Three RCTs were included. There was clinical heterogeneity with regard to cancer stage and location as well as operative techniques and adjuvant treatments. Functional outcomes (FO) that were reported by at least two studies were International Consultation on Incontinence Questionnaire (ICIQ), International Index for Erectile Function (IIEF), Jorge-Wexner incontinence score (J-W). Difference was observed in ICIQ at 9 months after surgery favoring LL (standard mean difference: - 0.66; 95% confidence intervals (CI): - 0.92, - 0.40; P = 0.37; I 2 = 0%). Difference was also observed in IIEF at 9 months favoring LL (mean difference: 7.43; CI: 1.86, 13.00; P = 0.16; I 2 = 50%). CONCLUSIONS Although our study has demonstrated the superiority of LL in genitourinary function preservation, these results should be taken with consciousness due to significant heterogeneity between included studies, small sample size, and potential bias. More high-quality studies are needed. PROSPERO CRD4202121099 https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021210998.

Abstract
OBJECTIVES This study investigated male voiding dysfunction (VD) or lower urinary tract function in rectal cancer (RC) patients after laparoscopic or open total mesorectal excision with pelvic autonomic nerve preservation (PANP). METHODS One hundred and eighty-seven male RC patients admitted between January 2016 and May 2019 were enrolled in this study, 112 of whom underwent laparoscopic total mesorectal excision (LTME) and 75 underwent open total mesorectal excision (OTME). The International Prostatic Symptom Score (IPSS) was compared between the two groups. RESULTS The postoperative IPSS in patients with RC was elevated on day 7 and gradually decreased during the first month after surgery. Compared with the OTME group, the IPSS scores decreased less in the LTME group at week 1, and months 1 and 3 postoperatively (6.82 ± 2.13 vs 10.15 ± 3.86, 5.70 ± 2.45 vs 7.21 ± 2.0, and 5.01 ± 2.09 vs 5.75 ± 2.55, respectively; P < 0.05). The VD rate was significantly lower in the LTME group than the OTME group at 1, 2, and 3 weeks postoperatively (21.4% vs 26.8%,13.4% vs 25.3%, and 9.8% vs18.6%, respectively; P < 0.05); however, there was no major difference in the incidence of VD 6 months postoperatively between the two groups (P > 0.05). VD was more frequent in the OTME group than the LTME group 6 months postoperatively, but the difference was not statistically significant (odds ratio = 1.857, 95% CI, 0.964-3.645, P = 0.064). CONCLUSIONS LTME may be superior to OTME with respect to PANP of lower urinary tract function in males with RC.

Abstract
In the pelvis, anatomic complexity and difficulty in visualization and access make surgery a formidable task. Surgeons are prone to work-related musculoskeletal injuries from the frequently poor design and flow of their work environment. This is exacerbated by the strain of surgery in the pelvis. These injuries can result in alterations to a surgeons practice, inadvertent patient injury, and even early retirement. Human factors examines the relationships between the surgeon, their instruments and their environment. By bridging physiology, psychology, and ergonomics, human factors allows a better understanding of some of the challenges posed by pelvic surgery. The operative approach involved (open, laparoscopic, robotic, or perineal) plays an important role in the relevant human factors. Improved understanding of ergonomics can mitigate these risks to surgeons. Other human factors approaches such as standardization, use of checklists, and employing resiliency efforts can all improve patient safety in the operating theatre.

Are Two Meshes Better than One in Sacrocolpopexy for Pelvic Organ Prolapse? Comparison of Single Anterior versus Anterior and Posterior Vaginal Mesh Procedures. Urol Int 2021; 106:282-290.

Abstract
INTRODUCTION Sacrocolpopexy (SC) is the main treatment option for the repair of anterior and apical pelvic organ prolapse (POP). Indications and technical aspects are not standardized, and the question remains whether it is necessary to place a mesh on both anterior and posterior vaginal walls, particularly in cases with only minor or no posterior compartment prolapse. The present study aimed to compare the anatomical and functional outcomes of single anterior mesh only versus anterior and posterior mesh procedures in SC. MATERIALS AND METHODS Our prospectively maintained database on POP was used to identify patients who had undergone either abdominal or mini-invasive SC from January 2006 to October 2019. Patients with symptomatic or unmasked stress urinary incontinence (SUI) were not included in the study and were treated using the pubo-vaginal cystocele sling procedure. Objective outcomes included clinical evaluation of pre-existing or de novo POP by the halfway system and POP-q classifications, as well as the development of de novo SUI. Subjective outcomes were assessed using the Pelvic Floor Impact Questionnaire (PFIQ-7) with questions on bladder, bowel, and vaginal functions. Persistent or de novo constipation and overactive bladder were defined as bowel symptoms and urinary urgency/frequency/urinary incontinence after surgery. RESULTS Ninety-five women with symptomatic anterior and apical POP underwent SC. Forty-one patients were treated with only anterior vaginal mesh (group A), and 54 with anterior and posterior mesh (group B). There were no differences between the pre- and post-operative characteristics of the 2 groups. In group B, there were 2 blood transfusions, 1 wound dehiscence, and 3 mesh erosions/extrusion after abdominal SC (Clavien-Dindo II), and in group A, there was 1 ileal lesion after laparoscopic SC (Clavien-Dindo III). There were no differences between the 2 groups in either anatomical or functional outcomes during 3 years of follow-up. CONCLUSIONS SC with single anterior vaginal mesh has similar results to SC with combined anterior/posterior mesh, regardless of the surgical approach. The single anterior mesh may reduce the risk of complications (mesh erosion/extrusion), and offers better subjective outcomes with improved quality of life. Anterior/posterior mesh may be justified in the presence of clinically significant posterior POP.

Abstract
An understanding of the anatomy of the Denonvilliers’ fascia is essential for successful surgical outcomes for patients with rectal cancer in the mid- to lower regions, especially near the seminal vesicles and prostate in males. Whether the correct surgical plane during a total mesorectal excision should be anterior or posterior to the Denonvilliers’ fascia is currently under debate. This study aimed to investigate the Denonvilliers’ fascia using micro-computed tomography (micro-CT) to acquire three-dimensional images nondestructively for assessments of the relationship between the Denonvilliers’ fascia, the mesorectal fascia, and neurovascular bundles to elucidate the correct anterior total mesorectal excision plane. Eight specimens were obtained bilaterally from four fresh human cadavers. Four specimens were stained with phosphotungstic acid to visualize the soft tissue, and micro-CT images were obtained; the other four specimens were stained with Masson’s trichrome to visualize connective tissue. Micro-CT images corroborate that the Denonvilliers’ fascia consists of a multilayered structure that separates the rectum from the seminal vesicles and the prostate. Specimens stained with Masson’s trichrome showed that the urogenital neurovascular bundle located at the posterolateral corner of the prostate is separated from the mesorectum by the Denonvilliers’ fascia. For the preservation of autonomic nerves necessary for urogenital function and optimal oncologic outcomes in patients with rectal cancer, a successful mesorectal excision requires a dissection plane posterior to the Denonvilliers’ fascia.

Abstract
BACKGROUND The optimal level of pedicle ligation during proctectomy for rectal cancer, either at the origin of the inferior mesenteric artery or the superior rectal artery, is still debated. OBJECTIVE The objective was to determine whether superior rectal artery ligation portends equivalent technical or oncologic outcomes. DESIGN This was a retrospective analysis of a rectal cancer database (2007-2017). SETTINGS The study was conducted at 6 tertiary referral centers in the United States (Emory University, University of Michigan, University of Pittsburgh Medical Center, The Ohio State University Wexner Medical Center, Vanderbilt University Medical Center, and Washington University School of Medicine in St. Louis). PATIENTS Patients with primary, nonmetastatic rectal cancer who underwent low anterior resection or abdominoperineal resection were included. MAIN OUTCOME MEASURES Anastomotic leak, lymph node harvest, locoregional recurrence-free survival, recurrence-free survival, and overall survival were measured. RESULTS Of 877 patients, 86% (n = 755) received an inferior mesenteric artery ligation, whereas 14% (n = 122) received a superior rectal artery ligation. A total of 12%, 33%, 24%, and 31% were pathologic stage 0, I, II, and III. Median follow-up was 31 months. Superior rectal artery ligation was associated with a similar anastomotic leak rate compared with inferior mesenteric artery ligation (9% vs 8%; p = 1.0). The median number of lymph nodes removed was identical (15 vs 15; p = 0.38). On multivariable analysis accounting for relevant clinicopathologic factors, superior rectal artery ligation was not associated with increased anastomotic leak rate, worse lymph node harvest, or worse locoregional recurrence-free survival, recurrence-free survival, or overall survival (all p values >0.1). LIMITATIONS This was a retrospective design. CONCLUSIONS Compared with inferior mesenteric artery ligation, superior rectal artery ligation is not associated with either worse technical or oncologic outcomes. Given the potential risks of inadequate blood flow to the proximal limb of the anastomosis and autonomic nerve injury, we advocate for increased use of superior rectal artery ligation.

El 12%, 33%, 24% y 31% estaban en estadio patológico 0, I, II y III respectivamente. La mediana de seguimiento fue de 31 meses. La ligadura de la arteria rectal superior se asoció con una tasa de fuga anastomótica similar a la ligadura de la arteria mesentérica inferior (9 vs 8%, p = 1,0). La mediana del número de ganglios linfáticos extirpados fue idéntica (15 contra 15, p = 0,38). En el análisis multivariado que tiene en cuenta los factores clínico-patológicos relevantes, la ligadura de la arteria rectal superior no se asoció con una mayor tasa de fuga anastomótica, una peor cosecha de ganglios linfáticos o una peor sobrevida libre de recurrencia locorregional, sobrevida libre de recurrencia o sobrevida global (todos p> 0,1).LIMITACIONES:Diseño retrospectivo.CONCLUSIONES:En comparación con la ligadura de la arteria mesentérica inferior, la ligadura de la arteria rectal superior no se asocia a peores resultados técnicos ni oncológicos. Debido a los riesgos potenciales de un flujo sanguíneo inadecuado del muñon proximal de la anastomosis y la lesión de los nervios autonómicos, proponemos una mayor realización de la ligadura de la arteria rectal superior.

Abstract
Purpose To investigate the relationship between the left trunk of the inferior mesenteric plexus (IMP) and the vascular sheath of the inferior mesenteric artery (IMA) and to explore anatomical evidence for autonomic nerve preservation during high ligation of the IMA in colorectal cancer surgery. Methods We evaluated the relationship in 23 consecutive cases of laparoscopic or robotic colorectal surgery with high ligation of the IMA at our institute. Anatomical dissection was performed on 5 formalin-fixed abdominal specimens. A novel anatomical evidence-based operative technique was proposed. Results Anatomical observation showed that the left trunk of the IMP was closely connected with the IMA and was involved in the composition of the vascular sheath. Based on anatomical evidence, we present a novel operative technique for nerve-sparing high ligation of the IMA that was successfully performed in 45 colorectal cancer surgeries with no intraoperative complications and satisfactory postoperative urogenital functional outcomes. Conclusion The left trunk of the IMP is involved in the composition of the IMA vascular sheath. This novel anatomical evidence-based operative technique for nerve-sparing high ligation of the IMA is technically safe and feasible.

Abstract
Intraoperative complication during laparoscopic mesorectal excision for rectal cancer is a common complication occurring in 11% to 15% of the cases. They are probably underestimated because not systematically reported. The most frequent intraoperative complications are haemorrhage (3-7%), tumour perforation (1-4%), bowel injury (1-3%), ureter injury (1%), urogenital injury (2%), other organ injury (<1%), and anastomotic complications (1%). The mechanisms, management and prevention of vascular port injury, inferior mesenteric artery bleeding, small bowel and colon perforation, ureteral and urethral injury, pelvic nerve damage, tumour perforation and anastomotic failure are described. This review underlines the necessity to prevent intraoperative complication to avoid operative death and severe side-effects.

Abstract
INTRODUCTION Minimally invasive surgery has gained a major role in the current management of colorectal disease since the introduction of laparoscopy in the early 1990s for colorectal procedures. The laparoscopic approach, in fact, is not exempt from the risk of intraoperative complications, some of which can occur outside the field of view. Aim of this chapter is to review the different types of complications that can happen during left colectomy, analyzing the causes, how to prevent them and what to do in case they occur. EVIDENCE ACQUISITION A literature search was carried out using the MEDLINE and PubMed databases for studies published between January 1980 and October 2020. The following terms were used for the search: complications, risk factors, colorectal surgery, colorectal resection, laparoscopy, left colectomy, intraoperative complications, splenic injury, intraoperative bleeding. EVIDENCE SYNTHESIS From our literature search we identified twenty-four studies, including two systematic reviews and metanalyses, that were the most pertinent to the subject. CONCLUSIONS Many different complications can occur during laparoscopic left colectomy. Maintaining control of the situation is important to provide a prompt solution to the occurred injury. Increasing the reporting rate of complications may help, in the future, to analyze the causes and improve management strategies, keeping in mind that the only surgeon who does not have complications is the one who does not operate.

Abstract
BACKGROUND Alterations in urinary function are complications of rectal cancer surgery. The aim of this study was to prospectively analyze the changes in urinary function in patients operated on for rectal cancer, and to identify risk factors that may have an impact on the deterioration of postoperative urinary function. METHODS A prospective study of urinary function in rectal cancer patients who had elective oncological resection with curative intention at the Arnau de Vilanova Hospital in Valencia, Spain, from January 2017 to March 2019. The evaluation of urinary function was performed using the International Prostate Symptom Score (IPSS) preoperatively, at 6 and 12 months after surgery. Predictive factors of urinary dysfunction were identified by univariate and multivariate analysis. RESULTS Ninety-four patients were enrolled in the study. Eighty-seven of them completed all the follow-up assessments (48 men and 39 women, mean age 65.74 ± 10.95 years,). The mean IPSS was 7.96 ± 7.59 preoperatively, 9.01 ± 6.81 at 6 months, and 8.63 ± 5.59 at 12 months, without statistically significant differences. There were no differences in IPSS between males and females. Preoperative urinary dysfunction was 39% and at 12 months, a deterioration occurred in 23 patients (26.4%). IPSS analysis of symptoms showed a statistically significant worsening of nocturia at 6 months (p = 0.002) and 1 year after surgery (p = 0.037) in women. American Society of Anesthesiologists (ASA) class (OR: 11, [95% CI2.4-53]; p = 0.010), surgical difficulty (OR: 4.5, [95% CI 1-19]; p = 0.027) and anastomotic leakage (OR: 14, [95% CI 1.6-117]; p = 0.010), were identified as independent risk factors for deterioration of urinary function after surgery. CONCLUSIONS Our study showed worsening urinary dysfunction after rectal cancer surgery in 26.4% of the patients. However, there were no statistically significant differences in mean IPSS scores at the three assessment times (preoperatively, 6 months, 12 months). ASA class, surgical difficulty, and anastomotic leakage may predict postoperative deterioration.

Abstract
The primary goal of surgery for rectal cancer is to achieve an oncologically safe resection, i.e., a radical resection with a sufficient safe margin. Total mesorectal excision has been introduced for radical surgery of rectal cancer and has yielded greatly improved oncologic outcomes in terms of local recurrence and cancer-specific survival. Along with oncologic outcomes, functional outcomes, such as voiding and sexual function, have also been emphasized in patients undergoing rectal cancer surgery to improve quality of life. Intraoperative nerve damage or combined excision is the primary reason for sexual and urinary dysfunction. In the past, these forms of damage could be attributed to the lack of anatomical knowledge and poor visualization of the pelvic autonomic nerve. With the adoption of minimally invasive surgery, visualization of nerve structure and meticulous dissection for the mesorectum are now possible. As the leading hospital employing this technique, we have adopted minimally invasive platforms (laparoscopy, robot-assisted surgery) in the field of rectal cancer surgery and standardized this technique globally. Here, we review a standardized technique for rectal cancer surgery based on our experience at Severance Hospital, suggest some practical technical tips, and discuss a couple of debatable issues in this field.

Abstract
Despite rapid advancements in laparoscopic surgical techniques and perioperative management, postoperative pain remains a significant clinical issue. We examined the analgesic efficacy of nefopam as an adjuvant in patient-controlled analgesia (PCA) for acute postoperative pain in patients undergoing laparoscopic colorectal cancer surgery. We retrospectively analyzed the medical records of 120 patients who did or did not receive 80 mg of nefopam as an adjuvant in fentanyl PCA; they were allocated to the nefopam (n = 60) or non-nefopam group (n = 60). The demographic, clinical, and anesthetic data, with data on pain severity and opioid administration at the postoperative anesthesia care unit (PACU) on postoperative days (PODs) 1, 3, and 5, were compared between the groups. The pain score and opioid administration did not differ at the PACU or on PODs 1, 3, or 5. The day of PCA discontinuation, time to pass flatus, length of the hospital stay, and incidence of nausea/vomiting, dizziness, and headache also did not differ between the groups. Fentanyl PCA with 80 mg of nefopam as an adjuvant did not have a superior analgesic effect after laparoscopic colorectal cancer surgery.

Abstract
Anterior rectal resection is a standard surgical procedure for treating carcinomas of rectum and distal sigmoid colon. In many cases of anterior rectal resection, postoperatively some level of fecal incontinence may occur. The aim of our study was to evaluate the impact of the colorectal anastomosis level on anorectal functional disorder. In our prospective study, the participants were patients diagnosed with carcinoma of rectum or distal sigmoid colon. All patients underwent standard open or laparoscopic anterior rectal resection. Six months after the surgery, the function of anorectum was evaluated in all participants. Finally, 38 patients were analyzed, including 13/38 (34.2%) patients with high rectal anastomosis, 11/38 (28.9%) with mid rectal anastomosis and 14/38 (36.8%) with low rectal anastomosis. Patients with a lower level of anastomosis had a statistically significantly greater number of stools, higher urgency and discrimination impairment, more pronounced solid, liquid and gas incontinence, and greater need for diapers (p<0.05 all). Therefore, patients with lower anastomosis had a statistically significant impairment of their quality of life and higher Wexner score (p<0.001 for both analyses). Our study results suggested reduced neorectal capacity to be the main pathophysiological factor for the development of postoperative anorectal function impairment.

Abstract
Despite the technical limitations of minimally invasive surgery, laparoscopic total mesorectal excision (LTME) for rectal cancer has short-term advantages over open surgery, but the pathological outcomes reported in randomized clinical trials are still in controversy. Minimally invasive robotic total mesorectal excision (RTME) has recently been gaining popularity as robotic surgical systems potentially provide greater benefits than LTME. Compared to LTME, RTME is associated with lower conversion rates and similar or better genitourinary functions, but its long-term oncological outcomes have not been established. Although the operating time of RTME is longer than that of LTME, RTME has a shorter learning curve, is more convenient for surgeons, and is better for sphincter-preserving operations than LTME. The robotic surgical system is a good technical tool for minimally invasive surgery for rectal cancer, especially in male patients with narrow deep pelvises. Robotic systems and robotic surgical techniques are still improving, and the contribution of RTME to the treatment of rectal cancer will continue to increase in the future.

Abstract
Background Intersphincteric resection (ISR) has been a preferable alternative to abdominoperineal resection (APR) for anal preservation in patients with low rectal cancer. Laparoscopic ISR and robotic ISR have been widely used with the proposal of 2 cm or even 1 cm rule of distal free margin and the development of minimally invasive technology. The aim of this review was to describe the newest advancements of ISR. Methods A comprehensive literature review was performed to identify studies on ISR techniques, preoperative chemoradiotherapy (PCRT), complications, oncological outcomes, and functional outcomes and thereby to summarize relevant information and controversies involved in ISR. Results Although PCRT is employed to avoid positive circumferential resection margin (CRM) and decrease local recurrence, it tends to engender damage of anorectal function and patients' quality of life (QoL). Common complications after ISR include anastomotic leakage (AL), anastomotic stricture (AS), urinary retention, fistula, pelvic sepsis, and prolapse. CRM involvement is the most important predictor for local recurrence. Preoperative assessment and particularly rectal endosonography are essential for selecting suitable patients. Anal dysfunction is associated with age, PCRT, location and growth of anastomotic stoma, tumour stage, and resection of internal sphincter. Conclusions The ISR technique seems feasible for selected patients with low rectal cancer. However, the postoperative QoL as a result of functional disorder should be fully discussed with patients before surgery.

Analgesic Efficacy of Preemptive Transversus Abdominis Plane Block in Patients Undergoing Laparoscopic Colorectal Cancer Surgery. J Clin Med 2020; 9:jcm9051577. [PMID: 32455933 PMCID: PMC7291263 DOI: 10.3390/jcm9051577] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 05/18/2020] [Accepted: 05/21/2020] [Indexed: 12/18/2022] Open
Abstract
Despite rapid advancements in laparoscopic surgical devices and techniques, pain remains a significant issue. We examined the efficacy of preemptive transversus abdominis plane (TAP) block for acute postoperative pain in patients undergoing laparoscopic colorectal cancer surgery. We retrospectively analyzed 153 patients who underwent laparoscopic colorectal cancer surgery with or without TAP block; among them, 142 were allocated to the TAP or non-TAP group. We performed between-group comparisons of demographic, clinical, and anesthetic data and pain scores at a postoperative anesthesia care unit (PACU) and at postoperative days 1, 3, and 5. There were no significant between-group differences in demographic and clinical characteristics. The mean arterial pressure, heart rate, and minimum alveolar concentration (MAC) were significantly lower in the TAP group at the start and end of surgery. The post-extubation bispectral index was significantly higher in the TAP group. There were no significant between-group differences in the pain scores and opioid consumption at the PACU or at postoperative days 1, 3, and 5, or in the time to pass flatus, the hospital stay length, and postoperative complications. Preemptive TAP block showed an intraoperative, but not postoperative, analgesic effect, characterized by a low mean arterial pressure, heart rate, and MAC.

Abstract
BACKGROUND Total Mesorectal Excision (TME) is the standard surgical technique for the treatment of rectal cancer. However, rates of sexual dysfunction ofup to 50% have been described after TME, and rates of urinary dysfunction of up to 30%. Although other factors are involved, the main cause of postoperative genitourinary dysfunction is intraoperative injury to the pelvic autonomic nerves. The risk is particularly high in the inferior mesenteric artery (IMA). The aim of this study is to compare pre- and post-TME sexual dysfunction, depending on the surgical approach usedin the inferior mesenteric vessels: either directly on the IMA, or from the inferior mesenteric vein (IMV) to the IMA. METHODS Prospective, randomized,controlled study of patients with rectal adenocarcinoma with neoadjuvant chemoradiotherapy, who will be randomly assigned to one of two groups depending on the surgical approach to the inferior mesenteric vessels. The main variable is pre- and postoperative sexual dysfunction; secondary variables are visualization and preservation of the pelvic autonomic nerves, pre- and postoperative urinary dysfunction, and pre- and postoperative quality of life. The sample will comprise 90 patients, 45 per group. DISCUSSION The aim is to demonstrate that the dissection route from the IMV towards the IMA favors the preservation of the pelvic autonomic nerves and thus reducesrates of sexual dysfunction post-surgery.

Robotic proctectomy for rectal cancer in the US: a skewed population. Surg Endosc 2019; 34:2651-2656.

Abstract
BACKGROUND Socioeconomic and racial differences have been associated with disparities in cancer care within the US, including disparate access to minimally invasive surgery for rectal cancer. We hypothesized that robotic approach to rectal cancer may be associated with similar disparities. METHODS The National Cancer Database (NCDB) was used to identify patients over 18 years old with clinical stage I-III rectal adenocarcinoma who underwent a proctectomy between 2010 and 2014. Demographic and hospital factors were analyzed for association with robotic approach. Factors identified on bivariate analyses informed multivariate analysis. RESULTS We identified 33,503 patients who met inclusion criteria; 3702 (11.1%) underwent robotic surgery with 7.8% conversion rate. Patients who received robotic surgery were more likely to be male, white, privately insured and with stage III cancer. They were also more likely to live in a metropolitan area, more than 25 miles away from the hospital and with a higher high school graduation rate. The treating hospital was more likely to be academic and high volume. CONCLUSIONS Robotic surgery is performed rarely and access to it is limited for patients who are female, black, older, non-privately insured and unable to travel to high-volume teaching institutions. The advantages of robotic surgery may not be available to all patients given disparate access to the robot. This inherent bias in access to robot may skew study populations, preventing generalizability of robotic surgery research.

Abstract
Rectal anatomy is one of the most challenging concepts of visceral anatomy, even though currently there are more than 23,000 papers indexed in PubMed regarding this topic. Nonetheless, even though there is a plethora of information meant to assist clinicians to achieve a better practice, there is no universal understanding of its complexity. This in turn increases the morbidity rates due to iatrogenic causes, as mistakes that could be avoided are repeated. For this reason, this review attempts to gather current knowledge regarding the detailed anatomy of the rectum and to organize and present it in a manner that focuses on its clinical implications, not only for the colorectal surgeon, but most importantly for all colorectal cancer-related specialties.

Abstract
Over the past four decades, the treatment algorithms for rectal cancer have fundamentally changed, which resulted in a considerable improvement of oncological outcomes. In this context, the surgical concept of total mesorectal excision and the implementation of multimodal treatment strategies represent key milestones. These improvements were complemented by a standardized histopathological work-up of the surgical specimen and the introduction of high-resolution magnetic resonance imaging (MRI) diagnostics. In addition, novel surgical techniques have been introduced, such as laparoscopic and robotic rectal resection. Other technological innovations include intraoperative pelvic neuromonitoring and fluorescence imaging. This review highlights the current evidence for selected, sometimes controversially discussed principles of surgical treatment strategies in rectal cancer.

Abstract
Urogenital complications due to pelvic autonomic nerve damage frequently occur following rectal surgery. We investigated whether total mesorectal excision (TME) with preservation of the Denonvilliers' fascia (DVF) can effectively prevent the removal of pelvic autonomic nerves through microscopy. Twenty consecutive male patients with mid-low rectal cancer who received TME with preservation or resection of the Denonvilliers' fascia (P and R groups, respectively) were included. Serial transverse sections from surgical specimens were studied histologically. Nerve fibers at the surfaces of the mesorectum were counted. Clinical correlation between the amount of nerve fibers removed and post-operative sexual function was analyzed. Nerve fibers closely localized to the DVF in the R group displaying rich erectile activity (positive anti-nNOS immunostaining). At the anterior surface of the mesorectum, the mean numbers of nNOS-positive nerve fibers per specimen in the P group were significantly lower than the R group (3.0 ± 1.8 vs. 5.0 ± 2.3, P < 0.05). Compared to the R group, patients in the P group had higher IIEF scores and better erectile function at 3 and 6 months post-operatively. The DVF is a key risk zone for pelvic denervation during laparoscopic TME. Preservation of the DVF can prevent the removal of autonomic nerves and protect post-operative erectile function. Clin.

Abstract
Background Some patients with low rectal cancer experience anorectal and urogenital dysfunctions after surgery, which can influence the long-term quality of life. In this study, we aimed to protect nerve function in such scenarios by performing intraoperative monitoring of pelvic autonomic nerves (IMPAN). Patients and methods We retrospectively investigated a series of 87 patients undergoing laparoscopic low anterior resection of rectal cancer. Nerve-sparing was evaluated both visually and electrophysiologically. IMPAN was performed by stimulating the pelvic autonomic nerves under processed electromyography of the internal anal sphincter. Urination, defecation, sexual function, and the quality of life were evaluated using validated and standardized questionnaires preoperatively and at follow-up, 12 months after surgery. Results Among a total of 87 patients (53 male and 34 female patients), IMPAN with simultaneous electromyography of the internal anal sphincter was performed in 58 (66.7%) patients. Bilateral positive IMPAN results for both measurements, indicating successfully confirmed pelvic autonomic nerve preservation, were obtained in 45 (51.7%) patients. No significant difference was found in terms of urogenital and anorectal functions between preoperative and postoperative patients with bilateral positive IMPAN (P>0.05). Compared to preoperative patients with IMPAN (unilateral) or without IMPAN, these patients exhibited higher International Prostate Symptom Score, a lower International Index of Erectile Function-5, and a lower Female Sexual Function Index score at 12 months postoperatively (P<0.05). Conclusion IMPAN is an appropriate method with which to laparoscopically protect nerve function.

Abstract
Purpose Controversy exists as to whether a high or low tie ligation of the inferior mesenteric artery (IMA) is the preferred technique in surgeries of the left colon and rectum. This study aims to contribute to the discussion as to which is the more beneficial technique by investigating the neurovasculature at each site. Methods Ten embalmed cadaveric donors underwent division of the inferior mesenteric artery at the level of the low tie. The artery was subsequently ligated at the root to render a section of tissue for histological analysis of the proximal (high tie), mid and distal (low tie) segments. Results Ganglia observed in the proximal end of seven specimens in the sample imply that there would be disruption to the innervation in a high tie procedure. Conclusion This study suggests that a high tie should be avoided if the low tie is oncologically viable.

Abstract
Poor early urinary outcomes after laparoscopy were reported in studies comparing laparoscopic versus open rectal cancer surgery. One possible explanation was that these studies might include a number of patients on the laparoscopic surgeons’ learning curve. This study aims to evaluate whether the learning curve of laparoscopic rectal cancer surgery influences early postoperative urinary dysfunction. Between September 2009 and December 2014, 208 consecutive patients undergoing laparoscopic rectal resection for rectal cancer were enrolled in the present study. All the clinical data were obtained from a prospectively compiled database. The primary outcomes were the incidences of postoperative urinary retention (POUR) and major urinary dysfunction requiring long-term urinary catheterization. POUR and major urinary dysfunction rate were 20.2 per cent (42/208) and 4.3 per cent (9/208), respectively. The learning curve analysis for operative time using the moving average method showed stabilization at 80 cases. Surgeon experience was divided into two periods: learning curve period (1–80 cases) and experienced period (81–208 cases). Multivariate analysis showed that older age (OR = 3.250, P = 0.006) and learning curve (OR = 2.241, P = 0.024) were independent risk factors for POUR. Learning curve was not significantly associated with increased rates of major urinary dysfunction (OR = 3.378, P = 0.092). Learning curve is a significant risk factor for increased rate of POUR after laparoscopic rectal cancer surgery. Technical training may be key to shorten the learning curve and limit its impact on the postoperative urinary complications.

Abstract
Aims: Even with the use of nerve-sparing techniques, there is a risk of bladder and sexual dysfunction after total mesorectal excision (TME). Laparoscopic TME is believed to improve this autonomic nerve dysfunction, but this is not demonstrated conclusively in the literature. In Indian patients generally, the stage at which the patients present is late and presumably the risk of autonomic nerve injury is more; however, there is no published data in this respect. Materials and Methods: This prospective study in male patients who underwent laparoscopic TME evaluated the bladder and sexual dysfunction using objective standardised scores, measuring residual urine and post-voided volume. The International Prostatic Symptom Score (IPSS) and International Index of Erectile Function score were used respectively to assess the bladder and sexual dysfunction preoperatively at 1, 3, 6 months and at 1 year. Results: Mean age of the study group was 58 years. After laparoscopic TME in male patients, the moderate to severe bladder dysfunction (IPSS <8) is observed in 20.4% of patients at 3 months, and at mean follow-up of 9.2 months, it was seen only in 2.9%. There is more bladder and sexual dysfunction in low rectal tumours compared to mid-rectal tumours. At 3 months, 75% had sexual dysfunction, 55% at median follow-up of the group at 9.2 months. Conclusion: After laparoscopic TME, bladder dysfunction is seen in one-fifth of the patients, which recovers in the next 6 months to 1 year. Sexual dysfunction is observed in 75% of patients immediately after TME which improves to 55% over 9.2 months.

Abstract
BACKGROUND The decision of ligation at the origin of the inferior mesenteric artery (IMA) or below the origin of the left colic artery (LCA) has remained a dilemma for surgeons in colorectal cancer surgery. The available studies are controversial. The objective of this meta-analysis is to compare the predictive significance of high versus low ligation in colorectal cancer surgery. METHODS A literature search done using Medline, EMBASE, GoogleScholar, and references. A meta-analysis was performed to analyze the 5-year overall survival (OS) of the high and low ligation using hazard ratio (HR) and 95% confidence interval (CI). We further analyzed 2 subgroups considering the level of lymph nodes (LNs) extension. That is IMA positive (+ve) and negative (-ve) LNs. Survival differences were analyzed. RESULTS A total of 3119 patients in 5 cohorts were included in this meta-analysis. The pooled HR results showed significant OS benefit of high ligation than low ligation (HR; 0.77, 95% CI: 0.66-0.89) in the "IMA +ve" group with 33% decreased risk, while there is no statistical significance in the "IMA -ve" (HR 0.66, 95% CI: 0.30-1.46) and the "all cases" group (HR 0.69, 95% CI: 0.41-1.15). CONCLUSION The pooled data showed high ligation of IMA has a better survival benefit for the patients with IMA positive LNs. It signifies high ligation should be recommended for the advanced cases or with the suspected high risk of IMA lymphatic metastasis. The limited number of articles demands future high-powered, well-designed randomized controlled trials (RCTs) for the further reliable conclusion.

Abstract
PURPOSE To compare patient quality of life (QoL) and short-term surgical outcomes between robotic anterior resection (r-AR) and laparoscopic (l-AR) approach. METHODS Consecutive patients having undergone either robotic or laparoscopic AR for adenocarcinoma were studied. All operations were performed by two surgeons experienced in laparoscopic and recently introduced robotic surgery. Surgical outcomes were determined by post-operative histology and short-term complications. QoL was prospectively assessed using the EORTC QLC-CR30 and QLC-CR29 questionnaires. RESULTS In total, 36 patients (18 r-AR) with a median follow-up of 12 months following surgery (9-month robotic and 20-month laparoscopic) were studied. The two groups were similarly matched for age and gender. Laparoscopic patients had a lower ASA grade (p = 0.02). There was no significant difference in surgical outcomes between groups. r-AR patients reported lower pain scales (2 ± 6 vs. 11 ± 13) (p = 0.04), lower levels of insomnia 0 vs. 8 ± 15 (p = 0.04) and a lower abdominal pain scale (2 ± 9 vs. 17 ± 27) (p = 0.04). Male impotence scores were higher in l-AR 33 ± 35 compared to r-AR 7 ± 21 (p = 0.03). CONCLUSION Despite its recent introduction to our centre, the quality of oncological resection using the robotic surgery is comparable to laparoscopy. Lower impotence and QoL scores in patients after robotic procedure may be explained on the basis of better visualisation and precise tissue handling.

Abstract
Sex and intimacy presents special challenges for the ostomate. Since some colorectal surgery patients will require either temporary or permanent stomas, intimacy and sexuality is a common issue for ostomates. In addition to the stoma, nerve damage, radiotherapy, and chemotherapy are often used in conjunction with stoma creation for cancer patients, thereby adding physiological dysfunction to the personal psychological impact of the stoma, leading to sexual dysfunction. The purpose of this paper is to describe the prevalence, etiology, and the most common types of sexual dysfunction in men and women after colorectal surgery and particularly those patients with stomas. In addition, treatment strategies for sexual dysfunction will also be described.

Abstract
Objective This study was performed to investigate the incidence of and potential risk factors for rectal pain after laparoscopic rectal cancer surgery. Methods We retrospectively analyzed data from 300 patients who underwent laparoscopic rectal cancer surgery. We assessed the presence of rectal pain and categorized patients into Group N (no rectal pain) or Group P (rectal pain). Results In total, 288 patients were included. Of these patients, 39 (13.5%) reported rectal pain and 14 (4.9%) had rectal pain that persisted for >3 months. Univariate analysis revealed that patients in Group P had more preoperative chemoradiotherapy, more ileostomies, longer operation times, more anastomotic margins of <2 cm from the anal verge, more anastomotic leakage, and longer hospital stays. Multivariate analysis identified an anastomotic margin of <2 cm from the anal verge and a long operation time as risk factors. The presence of diabetes mellitus was a negative predictor of rectal pain. Conclusions In this study, the incidence of rectal pain after laparoscopic rectal cancer surgery was 13.5%. An anastomotic margin of <2 cm from the anal verge and a long operation time were risk factors for rectal pain. The presence of diabetes mellitus was a negative predictor of rectal pain. Thus, the possibility of postoperative rectal pain should be discussed preoperatively with patients with these risk factors.

Abstract
Although we have seen revolutionary changes with multi-disciplinary management of patients with rectal cancer, the evaluation of genito-urinary sequelae remains of great concern. Precise pre-operative evaluation with validated scores allows detection of urinary disorders in 16 to 23% of patients, and sexual disorders in nearly 35% of men and 50% of women. Regardless of the surgical approach, it is fundamental to respect the autonomic innervation during total mesorectal excision in order to prevent these sequelae. Identification of these nerves can be facilitated by intra-operative neuro-stimulation. In spite of these precautions, de novo urinary sequelae are observed in nearly 33% of patients and bladder evacuation disorders in 25% of patients. Advanced age, pre-operative urinary disorders, female gender, and abdomino-perineal resection are independent risk factors for urinary sequelae. Early post-operative urodynamic abnormalities might be predictive of these sequelae and justify early physiotherapy. Likewise, sexual sequelae such as erectile and/or ejaculatory disorders, dyspareunia and lubrication deficits result in de novo cessation of sexual activity in 28% of men and 18% of women. Advanced age, neo-adjuvant radiation therapy, and abdomino-perineal resection are independent risk factors for sexual dysfunction. Pharmacotherapy with sildenafil has proven useful in the treatment of erectile disorders. Genito-urinary and ano-rectal sequelae occur concomitantly in more than one of ten patients, suggesting a potential common pathophysiology.

Abstract
AIM Whether or not nerve-sparing rectal-cancer surgery can effectively prevent removal of the pelvic autonomic nerves has not been substantiated microscopically. We aimed to analyse the quality of nerve preservation in female patients by quantifying residual nerve fibres in total mesorectal excision specimens, to analyse pro-erectile function of the nerve fibres removed and to determine risk factors for pelvic denervation. METHOD Serial transverse sections from female patients, 64 ± 18 years of age, were studied after the mesorectal fascia was inked and studied histologically [using anti-S100 and anti-neuronal nitric oxide synthase (nNOS) antibodies]. Nerve fibres located within 1 mm of the inked surface were counted and analysed according to type of surgery, tumour location, pT stage, circumferential resection margin and the necessity for a posterior colpectomy. RESULTS Twelve specimens were analysed. Per specimen, the mean number of nerve-fibre sections outside the mesorectum was 5.3 ± 3.6 (range: 1-12). The mean number of fibres per specimen was 6.4 ± 4.1 in patients having a low-rectal tumour and 4.4 ± 2.9 in those with mid or higher rectal tumours (P = 0.42). The mean number of fibres was higher (9.2) for T4 tumours than for T2/T3 tumours (5.0 ± 3.5), but this difference was not statistically sigmificant (P = 0.25). Patients having abdominoperineal excision, a posterior colpectomy or a circumferential resection margin of less than 1 mm had significantly more nerve fibres in the specimen (10.6 ± 1.9 vs 4.4 ± 2.8; P = .041). Fibres localized at the anterolateral rectum corresponded to branches of the neurovascular bundle, expressing rich pro-erectile activity (positive anti-nNOS immunostaining). CONCLUSION The neurovascular bundle is a key risk zone for pelvic denervation during total mesorectal excision. Abdominoperineal excision, posterior colpectomy and an invaded circumferential resection margin are associated with perineal denervation.

Abstract
Confusion remains as to what is meant by Denonvilliers' fascia. This review searched the literature on pelvic surgical anatomy to determine whether there is agreement with Denonvilliers' original description and its implication in defining the correct anterior plane of dissection when mobilizing the rectum. The original French description of the fascia was translated into English and then compared both with French and with English studies identified by searching PubMed, Medline and Scopus from 1836 to June 2015. Special emphasis was given to the years between 1980 and 2015 in order to capture the literature pertinent to, and following on from, the description of total mesorectal excision for rectal cancer. The final literature search revealed 16 studies from the original 2150 citations. Much of the debate was concerned with the origin and development of the fascia, arising from either the 'fusion' or the 'condensation' of local primitive tissue into a mature 'multilayered' structure. Controversy regarding the correct plane of rectal mobilization occurs as a result of different interpretations by surgeons, anatomists and radiologists and bears little resemblance to Denonvilliers' original description. This may reflect wide anatomical variability in the adult pelvis or a form of dissection artefact. Further study is required to investigate this. Logically, for both men and women, the plane of rectal mobilization should be behind Denonvilliers' fascia and between it and the fascia propria of the rectum.

Abstract
The advent of total mesorectal excision (TME) together with minimally invasive techniques such as laparoscopic colorectal surgery and robotic surgery has improved surgical results. However, the incidence of bladder and sexual dysfunction remains high. This may be particularly distressing for the patient and troublesome to manage for the surgeon when it does occur. The increased use of neoadjuvant and adjuvant radiotherapy is also associated with poorer functional outcomes. In this review, we evaluate current understanding of the anatomy of pelvic nerves which are divided into the areas of the inferior mesenteric artery pedicle, the lateral pelvic wall and dissection around the urogenital organs. Surgical techniques in these areas are discussed. We also discuss the results in functional outcomes of the various techniques including open, laparoscopic and robotic over the last 30 years.

Abstract
Background Urinary, sexual and anorectal sequelae are frequent after rectal cancer surgery and were found to be related to intraoperative neurogenic impairment. Neuromonitoring methods have been developed to identify and preserve the complex pelvic autonomic nervous system in order to maintain patients’ quality of life. So far no randomized study has been published dealing with the role of neuromonitoring in rectal cancer surgery. Methods/design NEUROS is a prospective two-arm randomized controlled multicenter clinical trial comparing the functional outcome in rectal cancer patients undergoing total mesorectal excision (TME) with and without pelvic intraoperative neuromonitoring (pIONM). A total of 188 patients will be included. Primary endpoint is the urinary function measured by the International Prostate Symptom Score. Secondary endpoints consist of sexual, anorectal functional outcome and safety, especially oncologic safety and quality of TME. Sexual function is assessed in females with the Female Sexual Function Index and in males with the International Index of Erectile Function. For evaluation of anorectal function the Wexner-Vaizey score is used. Functional evaluation is scheduled before radiochemotherapy (if applicable), preoperatively (baseline), before hospital discharge, 3 and 6 months after stoma closure and 12 months after surgery. For assessment of safety adverse events, the rates of positive resection margins and quality of mesorectum are documented. Discussion This study will provide high quality evidence on the efficacy of pIONM aiming for improvement of functional outcome in rectal cancer patients undergoing TME.
