Effect of partial preservation versus complete preservation of Denonvilliers’ fascia on postoperative urogenital function in male patients with low rectal cancer (PREDICTION): protocol of a multicentre, prospective, randomised controlled clinical trial

IntroductionTotal mesorectal excision (TME) has been the gold standard for the surgical treatment of mid-low rectal cancer, but traditional TME removal of Denonvilliers’ fascia (DVF) is too low and is...

Impact of rectal spacer on toxicity reduction in men treated with proton versus photon therapy.

247 Background: Dose escalation in prostate cancer (PCa) radiotherapy (RT) is limited by toxicity to surrounding tissue, including the rectum. Rectal spacers improve bowel toxicity in men treated with photons (i.e. IMRT). However, the relative benefit of rectal spacers in men treated with protons remains unknown. Further, proton therapy may result in high-dose exposure to the anterior rectal wall due to lateral penumbra with conventional opposed lateral beam arrangement. We hypothesize that rectal spacers will confer greater toxicity benefit in the setting of proton therapy compared with photon therapy. Methods: We conducted an IRB approved, single institution, retrospective review of patients receiving definitive conventional or moderate hypofractionated photon IMRT or pencil-beam scanning proton RT for localized PCa from 2018-2021. Four cohorts were compared: Photon with (Ph+RS) or without (Ph-RS) rectal spacer, and proton with (Pr+RS) or without (Pr-RS) rectal spacer. Rates of pelvic nodal treatment were equivalent between protons and photons within the +/- rectal spacer cohorts. Acute (<3 months) and late (≥ 3 month) toxicity was compared amongst the four cohorts. Cumulative incidence of physician-reported grade 1-2 gastrointestinal (GI) toxicity (CTCAE V5.0) was compared using Chi-square or Fisher’s exact test. Patient-reported bowel toxicity was evaluated using International Prostate Expanded Prostate Composite Index- Clinical Practice (EPIC-CP) and compared using linear mixed modeling. Results: 164 patients were eligible for analysis: 38 Ph-RS, 50 Ph+RS, 26 Pr-RS, & 50 Pr+RS. Median follow-up was 17.6 months. In men treated with protons, physician-reported acute G1-2 GI toxicity was significantly lower in men with versus without rectal spacer (6.12 vs 30.77%, Pr+RS vs Pr-RS, respectively; p=0.009) and there was a trend towards lower late G1-2 GI toxicity (8.51 vs 26.09%, Pr+RS vs Pr-RS, respectively; p=0.08). In men treated with photons, there were no significant differences in physician-reported acute or later GI toxicity with versus without rectal spacer. No significant differences in patient-reported outcomes were observed with versus without spacer in the proton or photon cohorts. Conclusions: Rectal spacer use was associated with a lower CTCAE grade 1-2 acute GI toxicity in men treated with protons, and this difference was not observed in men treated with photons. While this study is limited by low sample size, a relatively greater benefit of rectal spacer with proton vs. photon therapy was observed. Further prospective analyses in larger cohorts are ongoing to validate these hypothesis-generating findings.

Natural Orifice Endosonographic Colposuspension With Rectopexy for Combined Pelvic Organ Prolapse: A Feasibility Study.

We describe a natural orifice technique for simultaneous endoluminal lateral suspension of apical vaginal wall and rectal prolapse fixation with ultrasound and fluoroscopic assistance. The technique is minimally invasive, can be performed under regional anaesthesia, and avoids laparotomy or use of a mesh in addition to preserving the uterus. This technique involves suprapubic transvaginal ventral suture colposuspension, fixation of the anterior rectal wall to the undersurface of the anterior abdominal wall and tack fixation of the posterior rectal wall to the underlying sacral promontory through a submucosal tunnel performed endoscopically with fluoroscopic and ultrasound assistance. Seven patients with a mean age of 63 years were followed between 3 to 11 months. This is a novel minimally invasive transluminal procedure that repairs concomitant rectal and vaginal prolapse in the same sitting. Improvement in the instrument design and incorporation of endoluminal robotic systems will enhance the technical ease. The study needs validation in larger series of patients with longer follow-up.

Genital surgical procedures for feminization in gender dysphoria

The necessity and the benefits of genital approximating surgery in gender dysphoria are established, therefore the indications after careful diagnostics are indisputable. For vaginoplasty, the method of choice is penile inversion, in which the penile skin is inserted as a pedicled flap into the prepared vaginal space. Alternatively, free skin grafts or intestinal segments can be used. Lifelong bougienage of the vagina is obligatory for all methods. The spectrum of complications after vaginoplasty is broad. Of particular note, although rare, is injury to the anterior rectal wall, from which rectovaginal fistulas can result. During the course strictures of the urinary meatus or also the neovagina occur. Corrections must often be surgically undertaken but conservative measures, e.g. intensified bougienage and topical estrogen treatment, can also be successful. Neovaginal infections are treated analogously to infections of a native vagina. A special situation is inflammation of the intestinal neovagina, which must be treated with mesalazine.

How Useful Is Endoscopic Ultrasound in Differentiating T3/T4a T Stage of Colorectal Cancer: A Prospective Study.

ObjectiveEndoscopic ultrasound (EUS) is an established method for staging of colorectal cancer. Nevertheless, prior assessments of its T stage accuracy have been limited, particularly ambiguity in assessed T3 and T4a stage. This study was to characterize the EUS image features and pay attention to distinguish T3 from T4a T stage.MethodsA total of 638 patients who prospectively underwent colorectal EUS were recorded. The final diagnoses were compared with the concurrent or follow-up histopathology. Univariate and multivariate logistic regressions were used to assess variation in diagnostic performance with case attributes.ResultsThe accuracies of EUS in classifying colorectal cancer for overall, T1, T2, T3, and T4a stages are 73.04, 62.32, 67.46, 71.26, and 83.52%, respectively. With attention to EUS image features, the lesion penetrates the entire wall and locates below the seminal vesicles or cervix is T3 stage. If the lesion locates above clearly-defined space between the anterior rectal wall and the posterior surface of the seminal vesicles or cervix, we identify as T4a stage; However, when located above seminal vesicles or cervix but on the posterior wall of the rectum, the lesion still considers as T3 stage. The tumor location and histological type are associated with inaccuracy T stage.ConclusionsEUS provides reliable diagnostic accuracy in the colorectal cancer stage. The seminal vesicles and cervix are the important markers to predict infiltration depth for T3/T4a stage. Furthermore, the tumor location, histological type, and EUS image features for each tumor T stage should warrant attention.

Transanal endoscopic rectal resection: immediate and long-term results

To analyze the results of transanal endoscopic microsurgery in patients with rectal tumors. We analyzed 87 transanal endoscopic resections of rectal benign tumors (35 patients) and rectal cancer cT1N0M0 (52 patients) for the period since 2012. There were 2 (3.8%) intraoperative intestinal wall perforations into abdominal cavity and 2 (3.8%) postoperative bleedings among patients with rectal cancer. Four (7.7%) patients developed recurrent rectal cancer (pT1N0M0 - 1 patient, pT2N0M0 - 3 patients; by tumor grades: G1 - 2 patients, G2 - 2 patients) within 1.6-5.2 years. All recurrent tumors were located on anterior rectal wall. In patients with rectal cancer, cumulative relapse-free survival was 0.923 (standard error 0.037), cumulative overall survival - 0.926 (standard error 0.043). There was 1 (4.3%) intraoperative intestinal wall perforation among patients with benign rectal tumors. Postoperative anastomotic leakage occurred in 1 (4.3%) patient. Recurrent benign tumors occurred in 2 (8.7%) patients with villous rectal tumors. No relapses were observed in patients with rectal adenomas (p=1.0). Transanal endoscopic rectal resection is effective for benign rectal tumors and rectal cancer pT1N0M0 with high relapse-free and overall survival and low complication rate. Risk factors of recurrence are tumor stage pT2N0M0, tumor location on anterior wall and distance from the anus over 10 cm.

Posterior Cloaca: Multicenter Experience of a Very Rare and Unusual Anorectal and Genitourinary Malformation.

Posterior cloacal malformations (PCMs) are distinguished from classical cloacal malformations by the posterior location of the common opening in the perineum. We aim to describe our experience of management of these rare and complex malformations. This study was a retrospective chart review of all patients with PCM who underwent treatment at Kalawati Saran Children's Hospital (KSCH), New Delhi, and Sanjay Gandhi Postgraduate Institute of Medical Sciences (SGPGIMS), Lucknow, between 2013 and 2021. Individual anatomical variations and their impact on the clinical presentation, management, and final outcome (cosmesis and function) were recorded and analyzed. During the study period, four girls with a median age of 2 (range: 0-5) years presented to us with PCM. Three patients were referred to KSCH as ambiguous genitalia whereas one patient was born at SGPGIMS with an antenatal diagnosis of "urorectal septal defect." On examination, three patients had the urogenital sinus (UGS) opening immediately anterior to the normally located anal opening (2 orifices), whereas one had a single orifice at the normal location of the anus with the UGS opening in the anterior rectal wall. Associated anomalies included: (a) hydrocolpos (n = 3), which was managed by a tube vaginostomy; (b) urethral duplication with dorsal atretic urethra (n = 3); (c) uterine didelphys (n = 1); (d) bilateral grade 5 vesicoureteric reflux (n = 1); and (e) vaginal calculus (n = 1). Total urogenital mobilization (anterior sagittal approach) with feminizing genitoplasty was performed for patients with UGS and normal anus (n = 3). In the patient with a single opening at the normal location of the anus, posterior sagittal ano-recto-urethro-vaginoplasty was performed. At a median follow-up of 24 months, three patients are continent for urine and stool, whereas one patient is yet to be toilet trained. PCMs are unusual complex malformations that necessitate meticulous clinical examination, detailed diagnostic workup, and multistaged surgical management. Management should be tailored as per each individual patient's anatomy and clinical presentation for an optimal outcome.

Taking “Trans-ano-rectal” out of ASTRA: An anterior sagittal approach without splitting the rectum

The anterior sagittal trans-ano-rectal approach (ASTRA) provides excellent exposure to the urethra and vagina for partial or total urogenital sinus mobilization and subsequent reconstruction for patients with urogenital sinus anomalies. It is a frequent approach to reconstruction for children with a high confluence. However, the division of the anterior anal external sphincter and the rectal wall in the ASTRA incurs morbidity, which include fecal incontinence if one veers from the midline, and increased risk of wound infection due to fecal soilage. We demonstrate a modified technique to the ASTRA without dividing the anterior anal sphincter and rectal wall, with achievement of comparable exposure and excellent vaginal mobilization and length.

The cutback revisited — The posterior rectal advancement anoplasty for certain anorectal malformations with rectoperineal fistula

BackgroundThe repair of rectoperineal fistulae can pose a significant challenge to the pediatric surgeon given the proximity of the fistula to the urethra in males and vagina in females. In these children, a simple cutback procedure may leave the neoanus in a position anterior to the center of the sphincter, which theoretically could impair future continence. We devised an adaptation of the cutback anoplasty which we call the posterior rectal advancement anoplasty (PRAA) to treat patients with a rectoperineal fistula that is both narrow in lumen and located within, but at the anterior-most limit of the sphincter complex. Material and MethodsPatient selection, operative steps, and perioperative care of patients undergoing PRAA are detailed. Results10 children (6 males, 4 females) underwent PRAA. There were no vaginal wall or urethral injuries. At 6 months postoperatively, all patients were passing stool spontaneously. No patients required dilation of the anoplasty in the postoperative period and there were no anal strictures identified. ConclusionsA modification of the cutback anoplasty can be performed in patients with a perineal fistula and the distal fistula tract within the sphincter complex. We have demonstrated that this can be performed safely and obviates the need for an anterior rectal wall dissection, thus eliminating the risk of injury to urethra or vagina.Level of evidence: IV

Patient acceptability and quality of self-administered intravaginal gel for pelvic MRI

Background: MRI of the pelvis can be limited for infiltrating lesions or those of same signal intensity as surrounding structures. Vaginal distension using aqueous gel counters this by defining the fornices, cervix and anterior rectal wall. This increases the accuracy of diagnosis and staging of various pelvic pathology, however, there is currently neither a universally accepted protocol for using gel nor focus on patient self-administration. Aims: To improve patient expectations regarding pelvic MRI with intravaginal gel, as well as the service we provide should they prefer self-administration and this produces vaginal distension of radiological quality equivalent to doctor-administration. Methods: Illustrated information explaining the benefits of gel and the technique of self-administration was sent to patients scheduled for pelvic MRI between March 2020 and April 2021 at our study centre. This included a questionnaire to assess understanding and preference for self-administration. Vaginal distension achieved on imaging was analysed using TeraRecon and compared between self and doctor-administered cases. Results: 38 of 45 patients opted for self-administration of gel. Those who identified as White British were more likely to self-administer. There was comparable quality of vaginal distension between self and doctor administered cases, with no significant difference between orthogonal measurements and retained gel volume. Conclusion: Self-administration of intravaginal gel for pelvic MRI is acceptable to patients and frees a doctor of this duty. It is a well tolerated technique which produces high quality vaginal distention on imaging. We recommend wider use of intravaginal and even rectal gel in the investigation of complex endometriosis and pelvic tumours.

Morphological prerequisites for the formation of fascial duplication in the elimination of damage to the anterior rectal wall during prostatectomy

Background Intraoperative rectal injury in prostatectomy patients is an uncommon but severe complication. Particular attention is paid to improving the results of healing damage to the anterior rectal wall during prostatectomy.Objective To study the morphological features of the parietal pelvic fascia and the rectal wall to substantiate the possibility of the formation of fascial duplication in the elimination of damage to the anterior rectal wall during prostatectomy.Material and Methods The authors carried out an intravital morphological analysis of the parietal pelvic fascia covering the levator rectum muscle and the anterior rectal wall in 10 men.Results The parietal pelvic fascia contains more powerful bundles of collagen fibers, which in certain areas are partially woven into the fibers of striated muscle tissue. The adventitia of the rectum is characterized by a looser arrangement of the interacting components of the formed connective and smooth muscle tissue. In the studied formations of the small pelvis, the thickness of collagen fibers separately and in the composition of bundles, as well as the cells of the differon and each fiber separately did not differ, which indicated the identity of their tinctorial properties in the compared zones.Conclusion Morphological analysis showed that when juxtaposing and touching the edges of the healing area of the surgical wound without tension, a stable and continuous scar of the fascial duplication is formed, which ensures reliable fusion of the stitched anatomical structures.

Sonographic appearance of malignant deep endometriosis of the rectum

In a symptomatic, 47-year-old woman with dysmenorrhea, dyschezia, and rectal bleeding, a transvaginal ultrasound demonstrated adenomyosis and an irregular hypoechoic nodule of 31 mm×12 mm×24 mm that infiltrated the anterior rectal wall and caused a retraction compatible with deep infiltrating endometriosis (Figure 1). After an elastography was conducted, the nodule stiffness was observed to be high (Figures 2 and 3). After a transvaginal scan following the intrarectal introduction of a physiological solution (Video), the nodule appeared to infiltrate the submucosa for 3 mm and caused 50% lumen stenosis (Figure 4). Contrary to what is reported for endometriomas, no specific sonographic signs of malignant transformation were evident. Total hysterectomy and partial rectal resection were performed by laparoscopy. Histopathology confirmed adenomyosis and revealed a moderately differentiated endometrioid adenocarcinoma, developed on a deep endometriosis of the rectum. Malignant transformation of endometriosis occurs in 0.7% to 2.5% of women, mainly after 45 years of age. Seventy-five percent of cases involve the ovaries and 25% involve extragonadal sites, mostly the rectum-sigmoid.

Vestibular anus, a surgical dilemma

It is a pleasure for me to draw attention in this issue of your admirable journal to recto-vestibular fistula. Vestibular anus means congenital presence of the anus in the vestibule behind the vaginal orifice. It shares a common wall between the vagina and the rectum. In addition to an abnormal cosmetic appearance, it leads to recurrent attacks of urinary tract and vaginal infections. In adult female patients, it leads to dyspareunia. Several techniques have been described for the treatment of this type of anomaly, however; the postoperative continence is not always satisfactory. Optimal surgical repair would be easy to assess minimum dissection to spare pelvic nerves and guide the rectal pouch through the muscles of continence and intact sphincter [1]. The surgeon must cautiously during surgical separation of the posterior vaginal wall from the anterior rectal wall to avert rectal wall tear.

868 The management of acute lower gastrointestinal bleeding using a Sengstaken-Blakemore tube

Abstract Introduction Acute lower gastrointestinal haemorrhage can potentially be life-threatening. We present a case of a massive rectal bleed which was managed successfully with a balloon tamponade device designed for upper gastrointestinal haemorrhage. Presentation of case A 75-year-old gentleman, with a history of human immunodeficiency virus and cirrhosis with portal hypertension, presented with bright red rectal bleeding. Investigations showed a low haemoglobin level (74 g/L) and deranged clotting. Oesophago-gastro-duodenoscopy demonstrated no fresh or altered blood. Flexible sigmoidoscopy revealed active bleeding from a varix within the anterior rectal wall 4 cm from the anal verge. Efforts to stop the bleeding, including endoscopic clips, adrenaline injection and rectal packing, were unsuccessful and the patient became haemodynamically unstable. A Sengstaken-Blakemore tube was inserted per rectum and the gastric balloon was inflated to tamponade the lower rectum. The oesophageal balloon was then inflated to hold the gastric balloon firmly in place. A computed tomography angiogram demonstrated no evidence of haemorrhage with balloon tamponade. After 36 h, the balloon was removed with no further episodes of bleeding. Discussion The application of a balloon tamponade device should be considered in the management algorithm for acute lower gastrointestinal bleed. Advantages include its rapid insertion, immediate results and ability to measure further bleeding after the catheter has been placed. Conclusions Sengstaken-Blakemore tube per rectum may effectively control massive low rectal bleeding when alternative methods have been unsuccessful.

Solitary Mass of the Male Pelvis

Solitary fibrous tumor (STF) initially described as a tumor of the pleura has now been recognized at multiple anatomical sites. Pelvic STFs consist about 6% of all STFs. We present the case of a man with a long standing pelvic STF. He had symptoms of increased frequency of loose stools with passage of mucus since 2 years. A laparotomy and excision of the mass was done, but the patient developed complications and was re-explored on postoperative day 4 which showed a small rent in the anterior rectal wall mucosa. A colostomy was done after which the patient had a steady recovery. These lesions can be tricky to deal with due to their vascular nature and size. With no defined management protocol, the treatment must be tailor made and be more cautious especially when the pathology is long standing, causing pressure symptoms.

SOLITARY RECTAL ULCER SYNDROME AND ITS RELATION TO SPECIFIC FOOD

Introduction: SRUS was rst identied as clinical identity in 1969. But the etiology is not known. Anal ssure, IBD, proctagia fugax and malignancy, rectal polyps, hemorrhoids, and infections. Rarely ischemia, trauma and cystic profunda colitis and Stercoral ulcers have to be excluded. Hence a careful history is important. Material and methods: Patients presenting with C/O constipation or straining at stools with difculty in passing motion with associated minimal bleeding per rectum on and off period less than a month were included in the study. All patients were investigated for stool for occult blood, Us abdomen, BMFT, CBP and exible sigmoidoscopy. Results:100 patients presenting with constipation and bleeding PR were investigated. Flexible sigmoidoscopy showed multiple pin point supercial ulcers on the anterior rectal wall without involvement of sigmoid colon. The incidence age group wise was seen very high between 20 to 60 years. M: F ratio 47:53. All were positive for stool for occult blood, negative for IBD and malignancy by biopsy. They responded to dietary changes i.e; veg, non spicy, non fried diet with antibiotic, mesalamine (400mg BD) and lactulose 15ml at bed time. 10 days after the test follow up sigmoidoscopy was found normal and patient asymptomatic even after 3 months. Discussion: The incidence of SRUS has become common irrespective of age and sex. The type of food used by all these patients was found to be more or less similar with majority of them using fast food, fried food, and spicy food. Stoppage of the above mentioned food with specic treatment for 10 days resulted in recovery with normal sigmoidoscopy. Conclusion: SRUS incidence is high in general population due to specic food type and evacuation behavior.

Transrectal Ultrasound Guided Hydrodistension – A New Surgical Way in Transgender Surgery

BackgroundCreating the neovaginal canal in transwomen is one of the most delicate steps of Genital Gender Affirming Surgery (GGAS). Injury to the rectum is a rare but serious complication that can lead to further surgery and even creation of a colostomy. AimImplementation of a novel hydrospacing technique (HST) based on transrectal ultrasound (TRUS)-guided hydrodistension. MethodsBetween June 2018 and June 2020 54 transwomen received GGAS with HST. Immediately before GGAS transperineal hydrodistension was performed using a TSK-Supra-Needle (20 Gauge, 120 mm length), that was placed under direct TRUS-guided visual control between Denonvilliers’ fascia and the anterior rectal wall. 40 – 60 ml normal saline were administered perineally to separate Denonvilliers’ fascia from the anterior rectal wall to create a dissection of at least 20 mm. For better intraoperative visualization the hydrodissected space was also dyed using 2ml of methylenblue while retracting the needle. A retrospectively analysed, clinically and demographically comparable series of 84 transwomen who underwent GGAS between June 2016 and June 2018 served as control group. All 138 surgeries were performed by the same experienced surgeon. OutcomesThe effect of the novel hydrospacing technique on neovaginal dimensions and operating time. ResultsPatients in both groups did not differ in baseline patient characteristics such as age and body mass index (HST 35 vs 38 years in control group, P = .44 and body mass index 26 vs 25 kg/m2, P = .73). Vaginal depth and width were significantly larger in the HST subgroup as compared to controls (14.4 cm vs 13.5 cm, P = .01 and 4.2 cm vs 3.8 cm, P < .001). No statistically significant difference occurred in intraoperative rectal injury (n = 0 in HST group, n = 2 in control group, P = .26). Median total OR-time was comparable for GGAS including HST before vaginoplasty to standard technique (211 minutes for HST vs 218 minutes; P = 0.19). Clinical implicationsThe proposed additional surgical step during GGAS is minimally invasive and safe, simplifies GGAS and potentially helps to avoid complications such as rectal injury. Strength & LimitationsSingle-surgeon series, limited follow-up time and no prospective randomization. ConclusionHST is a safe and feasible procedure, which facilitates a safe preparation of the neovaginal canal during male to female GGAS.Panic A, Rahmani N, Kaspar C, et al.

Robotic TAMIS: A Technical Note Comparing Si® versus Xi®

Transanal minimally invasive surgery (TAMIS) can be performed robotically assisted (R-TAMIS) for easier rectal defect suture closure particularly on the anterior rectal wall. The surgical technique described in this technical note emphasizes three safety points: 1) decreased likelihood for rectal injury when the ports are inserted into the GelPOINT® Path Transanal Access Platform (Applied Medical, Rancho Santa Margarita, California) on the back table rather than being inserted into the rectum; 2) decreased external collision between ports when using ports of different length; and 3) increased stabilization of pneumorectum when insufflating with an AirSeal™ port (Intelligent Flow System, ConMed, Utica, New York). Although R-TAMIS can be safely performed with the da Vinci® Si® or Xi® (Intuitive Surgical Inc., Sunnyvale, California) patient cart, the following differences are noteworthy: a) the Si® vertically-mounted arms design forces the patient in an uncomfortable position with asymmetrical hip flexion as opposed to the Xi® boom-mounted horizontal arm design; b) the 28cm circumference of each Si® patient cart arms operating between the patient’s legs offer decreased maneuvering freedom as opposed to the 19cm circumference of the Xi® counterparts; and c) the abduction pattern of movement of the Si® arms potentially increases the risk of external collision with the patient’s legs as opposed to the Xi® “jack-knife” pattern of movement.
