Obstructed Defecation Syndrome: Analysis of the Efficacy and Mid-Term Quality of Life of an Innovative Robotic Approach.

Background: The goal of our research is to demonstrate how the combination of Rectal wall Plication (RP) and robotic Ventral Mesh Rectopexy (VMR) results in a safe and effective operation that provides superior outcomes for patients with Obstructed Defecation Syndrome (ODS). Methods: In a total of 78 women with ODS with posterior compartment prolapse, 30 had VMR whereas 33 received VMR plus RP. We assessed VMR and VMR + RP's efficacy and safety, as well as their influence on quality of life and sexual function. Results: At the median follow-up, both groups' POP-Q categorization scores for the posterior compartment decreased (p < 0.001). In terms of quality of life, the PISQ-12 showed an increase in sexual quality (30.12 ± 7.12 vs. 35.98 ± 5.98 in the VMR group and 29.65 ± 6.45 vs. 29.65 ± 6.45 in the VMR + RP group, p = 0.041). In the VMR + RP group, the number of sexually active patients with at least two sexual interactions per month rose (p = 0.033). At the median follow-up, the ODS score values differed significantly (7.11 ± 1.65 vs. 1.88 ± 1.89, p = 0.013). Conclusions: The combination of rectal wall plication and ventral mesh rectopexy may result in improved bowel function and quality of life.

Anatomical and functional outcomes of rectal prolapse treatment with laparoscopic pelvic organ prolapse suspension versus laparoscopic ventral mesh rectopexy

AbstractAimVery few studies have compared laparoscopic pelvic organ prolapse suspension (POPS) and laparoscopic ventral mesh rectopexy (LVMR) in the treatment of rectal prolapse, particularly regarding the comparison of improvement rates in obstructed defecation syndrome (ODS). This study aimed to compare the anatomical and functional outcomes of these two methods over a long‐term follow‐up period.Patients and methodsThis retrospective study was conducted on 120 female patients diagnosed with rectal prolapse who underwent surgery at the Colorectal Surgery Department of Shahid Faqihi Hospital in Shiraz, Iran, between October 2015 and October 2022. The patients were categorised into two groups based on their surgical procedures: 58 underwent LVMR in the first group, and 62 underwent POPS in the second group.ResultsRecurrence of prolapse occurred in 7 (12.1%) patients in the LVMR group and 5 (8.1%) patients in the POPS group (P = .550). The mean operation time, mean length of hospital stay, Visual Analogue Scale score, early and late post‐operative complications, Cleveland Clinic Incontinence Score, ODS symptoms, and Wexner Constipation Scores did not differ significantly between the two groups.ConclusionBoth laparoscopic POPS and LVMR techniques significantly improved the anatomical and functional outcomes in the treatment of rectal prolapse and obstructed defecation. LVMR and POPS can each be considered first‐line treatment options for rectal prolapse, depending on the specific case.

Результаты хирургического лечения проляпса в области заднего сегмента тазового дна у пациенток с раком молочной железы на фоне эндокринной терапии

The cause of pelvic organ ptosis in women is damage or weakening of the connective tissue and muscle structures of the pelvic floor, which normally serve as a supporting framework for pelvic organs and are estrogen-dependent. Most women with receptor-positive breast cancer are prescribed adjuvant endocrine therapy after surgery to suppress estrogen levels. The authors investigated the results of surgery of posterior pelvic floor segment prolapse in this category of patients (n = 50). The study was conducted in a comparative aspect with a group of patients who do not suffer from breast cancer (n = 50). For anatomical correction of prolapse, posterior colporaphy, anterior levatoroplasty or sphincterolevatoroplasty, resection of rectal mucosa prolapse using the STARR method, sacrocolporectopexy, depending on the pathology of certain structures of the pelvic floor, were performed. The evaluation of the treatment results was carried out after 3 years using clinical, radiological (defecography) and physiological methods (anorectal functional tests) studies. The authors showed that the symptoms of obstructive defecation and anal incontinence were less amenable to correction in patients with endocrine therapy. The authors concluded that it is necessary to prevent pelvic organ prolapse and the advantages of surgical correction of the initial forms of prolapse in this group of patients.

Long Rectal Cuff and Remnant Mesorectum Are Major Preventable Causes of Ileal Pouch Failure.

Long rectal cuff (>2 cm) and remnant mesorectum are known causes of pouch dysfunction due to obstructive defecation, as well as pelvic sepsis after prolonged obstruction. The aim of this study is to report the rates and the management of patients who underwent re-do ileal pouch anal anastomosis due to pouch failure associated with retained mesorectum and long rectal cuff. This is a retrospective study. The investigation is based on a quaternary inflammatory bowel disease center. Patients undergoing re-do ileal pouch anal anastomosis surgery and had long rectal cuff and/or remnant mesorectum between September 2016 and September 2023 were included in the study. The main outcomes were functioning pouch rate and functional results. Of the 245 patients who underwent re-do ileal pouch anal anastomosis surgery, 98 (40%) patients had long rectal cuff and/or remnant mesorectum. Re-do ileal pouch anal anastomosis in this patient group was successful (92%) at a median follow-up of 28 (18-52) months. The retrospective nature of the study and this is the experience of a single specialized center. Long rectal cuff and remanent mesorectum are major causes of pouch failure which can be successfully managed with re-do ileal pouch anal anastomosis surgery. Nearly half of pouch failure patients who had successful re-do ileal pouch anal anastomosis surgery initially received unnecessary biologic therapy before coming to our center. See Video abstract.

FP8.8 - LumenEye XI rigid digital rectoscope in the assessment of anorectal symptoms: a sustainable substitute for outpatient flexible sigmoidoscopy?

Abstract Aims To evaluate the acceptability, safety and diagnostic yield of the LumenEye XI in the assessment of anorectal symptoms. Methods Consecutive patients with anorectal symptoms, referred to the colorectal unit by their general practitioner, had a full clinical assessment followed by endoscopic examination using the LumenEye XI by a consultant colorectal surgeon. Results 59 consecutive patients,16 being male, were examined. The median age was 59 years (range 27-90). The main reported presenting complaints were rectal bleeding (n = 18, 21.4%), proctalgia (n = 10, 15.5 %), faecal incontinence (n=12, 14.3%), obstructive defaecation (n=7, 8.3%), anorectal swelling (n = 7, 8.3%), and mucous discharge (n = 2, 2.4%). The main findings were haemorrhoids (n= 18, 22.5%), rectal prolapse and rectocoele (n=14, 17.5%), and inflammatory conditions (proctitis, anal fistula, pouchitis) (n=4, 5%). One patient was diagnosed with rectal cancer. 19 patients (23.75%) had normal findings. 13 patients (22%) were referred for further investigations. Out of the 18 patients with rectal bleeding, 16 had a definitive diagnosis made with LumenEye. The diagnoses in patients with rectal bleeding were haemorrhoids (n=15, 53.6%), inflammation (n=4, 14.3%), prolapse (n=2, 7.1%), and ulceration (n=1, 3.6%). No cause could be identified in 2 of these patients. The rectosigmoid junction was visualised in all patients who had an intact rectum (57 out of 59 patients). All patients tolerated the procedure well, with no complications. Conclusions LumenEye XI is safe and well accepted by patients with good diagnostic accuracy. It therefore offers a potential solution to helping to relieve the endoscopy burden and enable cost savings by reducing the number of outpatient flexible sigmoidoscopies.

FP4.11 - Patient Reported Outcome Measures (PROMs) of Altemeier’s Procedure

Abstract Rectal prolapse (RP) is a debilitating condition that can be managed using Altemeier’s procedure (AP). We aimed to evaluate patient-reported long-term outcomes following AP focusing on symptoms, post-procedure pain and overall satisfaction. Patients who underwent AP in a District General Hospital between January 2015 and December 2022 were reviewed. Patients were contacted by telephone and interviewed using a standardised questionnaire. Likert scores and a Numeric Rating Scale (NRS) were used to assess functional outcome and pain respectively. Indication for surgery, recurrence, and data on further procedures were also collected. Out of 38 patients identified, 20 who underwent AP over the study period (mean age 78 years, s.d. 7.44, Female=20) were contactable and included in our study. In combination with RP, indications for surgery included faecal incontinence, obstructive defaecation symptoms, pain and rectal bleeding. At the time of follow up, 75% of patients reported their initial symptoms to be slightly or much better, 10% reported no change and 15% reported slightly worse symptoms. Prior to AP, 45% of patients reported no pain compared to 70% post-procedure. Severe pain was reported by 30% of patients pre-Altemeier’s compared to five percent post-procedure. Recurrence of RP occurred in 40% patients. 30% of patients required a second procedure. Overall, 80% of patients were satisfied with their outcome and 90% would recommend AP to friends and family. Most patients reported better functional outcome and good overall satisfaction, despite 30% requiring a further procedure. Our study was limited by small sample size and subjectiveness of patient reporting.

Clinical value of transperineal ultrasound in evaluating the diagnostic grade of rectocele in Chinese women with obstructed defecation syndrome: An observational study.

We aimed to evaluate the effectiveness of transperineal ultrasound (TPUS) in diagnosing rectocele, rectal intussusception (RI), enterocele, perineal descent (PD), and cystocele in Chinese women with obstructed defecation syndrome (ODS), and to determine the grading of rectocele via TPUS. Between January 2019 and December 2021, 107 obstructed defecation syndrome patients, with a mean age of 49.76 years, received TPUS and defecation proctography (DEP). Both methods were used to diagnose anorectal angle, rectocele, RI, enterocele, and PD, while cystocele and uterine prolapse were diagnosed only through TPUS. Agreement between DEP and TPUS diagnostic results was compared using Cohen kappa statistics. Seventy-six rectoceles were reported following DEP and 72 after TPUS. DEP detected 7 enteroceles, 6 of which were diagnosed simultaneously by TPUS. 43 patients presented dyssynergic defecation (DD) upon DEP, while 51 upon TPUS. DEP and TPUS detected PD in 13 and 11 patients respectively, and RI in 82 and 73, respectively. Rectocele (kappa = 0.738), RI (kappa = 0.711), DD (kappa = 0.774), enterocele (kappa = 0.847), and PD (kappa = 0.625) were obtained by Cohen kappa statistics, which indicated a good agreement between DEP and TPUS. The cutoff values for the diagnosis of moderate and severe rectocele with TPUS were 12.05 mm (AUC: 0.941) and 18.50 mm (AUC: 0.977), respectively. The DEP-determined and TPUS-determined anorectal angles were significantly correlated in the resting and Valsalva states (P < .01). Compared with DEP, while maintaining good agreement in detecting rectocele, RI, DD, enterocele, and PD, TPUS is a repeatable and noninvasive alternative. Threshold values of 12.05 mm and 18.50 mm on TPUS may diagnose moderate and severe rectocele, respectively.

Recurrent pelvic prolapse after pelvic organ prolapse suspension (POPS): Analysis and treatment of an emerging clinical issue

ObjectivesTo investigate pelvic organ prolapse (POP) after a novel abdominal prosthetic surgical technique – ‘pelvic organ prolapse suspension’ (POPS) – that has been proposed recently as an easily reproducible laparoscopic technique for the treatment of multicompartmental POP and rectal prolapse. This study also aimed to analyse treatment strategies of recurrent POP after POPS, reporting on anatomical, subjective and functional outcomes following recurrence surgery. MethodsPatients with a symptomatic prolapse relapse after POPS were collected and analysed prospectively at a single tertiary care institution. Each patient was offered a multidisciplinary clinical and radiological evaluation pre-operatively. ResultsTwenty-five women with a median age of 59 [interquartile range (IQR) 49–73] years were enrolled in the study. Of these, 88 % were menopausal. All patients had high-grade (Pelvic Organ Prolapse Quantification System stage > 2) recurrent posterior vaginal wall-predominant prolapse after POPS. Multicompartmental prolapse was found in 64 % of patients. All women complained of vaginal bulging associated with obstructed defaecation syndrome (ODS) symptoms. Surgical treatment consisted of laparoscopic ventral rectopexy (VR) in all 25 cases (100 %), and concomitant sacral colpopexy (SCP) with previous mesh removal in 16 cases (64 %). No anatomical recurrences were observed after median follow-up of 12 (IQR 3–18) months. Overall subjective improvement after surgery was high in all patients (Patient Global Improvement Index ≤ 2). ConclusionsRecurrent POP following POPS appears to predominantly involve the posterior vaginal wall, with associated ODS symptoms. A multidisciplinary approach is advisable for treatment of these patients. Minimally invasive VR alone or in combination with SCP seems to represent an effective treatment.

Electroneuromyographic examination of pelvic floor muscle dysfunction in patients with descending perineum syndrome

Aim: to assess the functional state of the pelvic floor muscles and their innervation in patients with descending perineum syndrome, manifested simultaneously by obstructive defecation and chronic neurogenic pelvic pain.Materials and methods: in 2022–2023, 51 patients (40 (78.4 %) women, 11 (21.6 %) men; age 50.9 ± 14.5 years) with pelvic organ prolapse, manifested by obstructive defecation and chronic neurogenic pelvic pain were examined at the Ryzhikh National Medical Research Centre for Coloproctology. All patients underwent high-resolution anorectal manometry and stimulation electroneuromyography according to a comprehensive neurophysiological protocol using a St. Mark’s electrode.Results: manometric patterns of functional defecation disorders were detected in 40 (78.4 %) patients, in the rest they were confirmed by defecography data and a negative evacuation test according to the Rome criteria IV. With stimulation electroneuromyography, neuropathy was detected in 68.6 % of cases by increasing the latency of the M-response of the pudendal nerve on the right or left. Complex neurophysiological diagnostics made it possible to additionally identify neuropathy in another 25.5 % of patients: according to changes in the mixed reciprocating reflex response (mixed feedback-reflex response) (efferent pathway) — in 17.7 % of cases; according to changes in the bulbocavernous reflex (efferent and afferent pathways) — in 7.8 % of cases. That is, neuropathy was determined in 94.1 % of patients in total.Conclusions:Functional diagnostic methods are an effective tool for studying the state of the pelvic floor muscle structures and their innervation and make it possible to identify pathogenetic links of disorders, the clinical manifestations of which are anal incontinence, neurogenic pelvic pain and proctogenic constipation in the form of obstructive defecation.Stimulation electroneuromyography makes it possible to detect disturbed innervation of the pelvic floor muscles and anal sphincter in the standard study of the M-response in 68.6 % of cases with perineal prolapse syndrome with a combination of proctogenic disorders and neurogenic pelvic pain. The use of a comprehensive neurophysiological protocol makes it possible to detect innervation disorders in 94.1 % of cases.

Laparoscopic Lateral Hysteropexy versus Hysterosacropexy in Women with Stage III Uterine Prolapse.

Background: Minimally invasive techniques in gynecological pathology have well-known benefits, the "gold standard" of uterine prolapse being currently managed laparoscopically. Laparoscopic lateral hysteropexy and hysterosacropexy are surgical techniques that can be performed for uterine prolapse. Laparoscopic management of such cases is recommended, but requires well-trained teams in laparoscopic surgery. Methods: This study is a prospective analysis of patients who required surgical treatment for stage III uterine prolapse, hospitalized in the Surgery Department of Constanta County Hospital, for which laparoscopic lateral hysteropexy or laparoscopic hysterosacropexy was performed. Results: Between 2016-2020, 61 patients were hospitalized with stage III uterine prolapse that required surgery. All patients underwent laparoscopic surgery. Symptomatology was dominated by urinary incontinence (50%, 44.89%) and obstructive defecation (16.66%, 18.36%). Intraoperative complications were encountered in 33.3% of cases undergoing laparoscopic hysterosacropexy and in 8.16% undergoing laparoscopic lateral hysteropexy. At one year, the recurrence rate was 2.04% for patients who underwent lateral hysteropexy and 8.33% for patients who underwent hysterosacropexy. No patient had a recurrence at the 3-year visit. Conclusions: Laparoscopic lateral hysteropexy is emerging as an appropriate, safe, and effective procedure to treat advanced apical prolapse that requires further clinical attention and development to fully understand its surgical place in the treatment of pelvic defects.

Comparison of Surgical Outcomes of Laparoscopic Ventral Mesh Rectopexy and Stapled Transanal Rectal Resection for Managing Obstructed Defecation Syndrome

Abstract Background: Obstructed defecation syndrome has several underlying causes and is a prevalent but poorly understood condition. It is characterized by the inability to pass stool even when one experiences the urge to defecate. Initial therapy for ODS usually involves diet modifications, pelvic floor exercises, and biofeedback, which can considerably reduce symptoms. Surgical intervention may be recommended for individuals who present with certain anatomical anomalies and who do not respond to conservative therapies. Objectives: To assess and compare the surgical outcomes of laparoscopic ventral mesh rectopexy (LVMR) and stapled transanal rectal resection (STARR) for ODS management. Design: The study conducted a retrospective review of prospectively gathered data on the outcomes of 162 patients treated for ODS at our facility between January 2015 and January 2022 using either LVMR or STARR. Settings: The study was conducted at our facility between January 2015 and January 2022, evaluating 162 patients with ODS who underwent either LVMR (118 patients) or STARR (44 patients). Patient and Methods: The Modified Longo’s Scores (MLS) were used as the primary evaluation tool, determined preoperatively and postoperatively at 1 month, 6 months, and 12 months. Sample Size: A total of 162 patients were included in the study, with 118 patients who underwent LVMR and 44 patients who underwent STARR for the treatment of ODS at our facility between January 2015 and January 2022. Results: Preoperative MLS for LVMR patients averaged 23.41, which was similar to that of STARR patients (23.52), showing no statistically significant difference. After 1 month, the mean MLS showed a significant decrease of 93.3% among LVMR patients and that of 18.0% among STARR patients from the preoperative mean MLS, indicating a significantly greater change among LVMR patients than among STARR patients. Similarly, after 6 months, the preoperative mean MLS for LVMR patients and STARR patients revealed a substantial decline of 95.4% and 6.5%, respectively, with LVMR patients experiencing a considerably greater change than STARR patients. After 12 months, the mean MLS showed a significant decrease of 96.6% and 3.6% among LVMR and STARR patients from the preoperative mean MLS, respectively, with change being significantly more among LVMR patients than STARR patients. Conclusion: LVMR can be the preferred method because it outperforms STARR in terms of alleviating ODS symptoms. Limitations: This research involved a retrospective study using a small sample size and a short follow-up period. Conflicts of Interest: None.

Analysis of factors that indicated surgery in 400 patients submitted to a complete diagnostic workup for obstructed defecation syndrome and rectal prolapse using a supervised machine learning algorithm.

Patient selection is extremely important in obstructed defecation syndrome (ODS) and rectal prolapse (RP) surgery. This study assessed factors that guided the indications for ODS and RP surgery and their specific role in our decision-making process using a machine learning approach. This is a retrospective analysis of a long-term prospective observational study on female patients reporting symptoms of ODS who underwent a complete diagnostic workup from January 2010 to December 2021 at an academic tertiary referral center. Clinical, defecographic, and other functional tests data were assessed. A supervised machine learning algorithm using a classification tree model was performed and tested. A total of 400 patients were included. The factors associated with a significantly higher probability of undergoing surgery were follows: as symptoms, perineal splinting, anal or vaginal self-digitations, sensation of external RP, episodes of fecal incontinence and soiling; as physical examination features, evidence of internal and external RP, rectocele, enterocele, or anterior/middle pelvic organs prolapse; as defecographic findings, intra-anal and external RP, rectocele, incomplete rectocele emptying, enterocele, cystocele, and colpo-hysterocele. Surgery was less indicated in patients with dyssynergia, severe anxiety and depression. All these factors were included in a supervised machine learning algorithm. The model showed high accuracy on the test dataset (79%, p < 0.001). Symptoms assessment and physical examination proved to be fundamental, but other functional tests should also be considered. By adopting a machine learning model in further ODS and RP centers, indications for surgery could be more easily and reliably identified and shared.

Early safety and efficiency outcomes of a novel interdisciplinary laparoscopic resection rectopexy combined with sacrocolpopexy for women with obstructive defecation syndrome and pelvic organ prolapse: a single center study

BackgroundObstructive defecation syndrome (ODS) defines a disturbed defecation process frequently associated with pelvic organ prolapse (POP) in women that substantially compromises quality of life. Conservative management offers limited relief and a surgical intervention may be required. This is characterized by individual approaches.Aim of the studyThis retrospective single center study evaluated the surgical and clinical short-term outcome of a novel interdisciplinary laparoscopic resection rectopexy (L-RRP) with mesh- sacrocolpopexy (L-SCP) for women suffering from ODS and POP.MethodsThe study participants underwent surgery in an interdisciplinary laparoscopic approach. Safety was the primary endpoint, assessed via postoperative morbidity classified by Clavien-Dindo scale. Secondary outcomes included evaluation of bowel function, fecal and urinary incontinence and pelvic organ prolapse status at 12 months follow-up. Additionally, a biological mesh (BM) was offered to women, who asked for an alternative to synthetic mesh material (SM).ResultsOf the 44 consecutive patients requiring surgery for ODS and POP, 36 patients underwent the interdisciplinary surgical approach; 28 patients with SM and 8 patients with BM. In total 5 complications occurred, four of them were classified as minor. One minor complication was observed in the BM group. One anastomotic leakage occurred in the SM group. The two ODS scores, the bowel dysfunction score, and the incontinence score improved significantly (p = 0.006, p = 0.003, p < 0.001, and p = 0.0035, respectively). Pelvic floor anatomy was fully restored (POP-Q 0) for 29 (80%) patients after surgery. 17 patients (47%) suffered from urinary incontinence before surgery, which was restored in 13 patients (76.5%).ConclusionsThe interdisciplinary approach with L-RRP and L-SCP and the use of a BM in a small subgroup were technically feasible, safe, and effective in this single center setting. The study’s retrospective design, the small sample size and the lack of comparators limit the generalizability of the findings requiring future randomized trials.Trial registrationRetrospectively registered at clinicaltrials.gov, trial number NCT05910021, date of registration 06/10/2023.

Laparoscopic resection rectopexy (RRP) combined with mesh sacrocolpopexy (SCP) for obstructed defecation syndrome with pelvic organ prolapse in an interdisciplinary approach.

Obstructive defecation syndrome (ODS) is frequently associated with pelvic organ prolapse (POP) and compromises the quality of life in affected patients. In cases conservative treatment fails surgical therapy is required. The video case study combines a laparoscopic resection rectopexy (RRP) with a mesh sacrocolpopexy (SCP) in an interdisciplinary surgical approach. In this video an 86-year-old woman with ODS and POP, suffering from a dolichocolon with rectal intussusception, an apical prolapse after total hysterectomy 1990, and occasional stress urinary incontinence underwent interdisciplinary laparoscopic surgery. A tubular anterior rectal and sigmoid resection with suture rectopexy as in a resection rectopexy (RRP) was combined with a sacrocolpopexy (SCP) using a synthetic mesh. Surgical outcome including postoperative morbidity, functional bowel evacuation, and POP reconstitution as in POP-Q score after surgery were documented. No intra- or postoperative complications occurred. At 6 months follow-up clinical outcomes for ODS, bowel dysfunction, and faecal control were improved. Anatomical outcome for POP and stress urinary incontinence symptoms were corrected. We report a promising interdisciplinary surgical approach as a single treatment option for the complex medical condition of women suffering from ODS and POP combining laparoscopic RRP with SCP. This surgical approach proved to be feasible, safe, and effective.

Characterization of obstructive defecation from a structural and a functional perspective

Background/aimsDefecation disorders can occur as a consequence of functional or structural anorectal dysfunctions during voiding. The aims of this study is to assess the prevalence of structural (SDD) vs functional (FDD) defecation disorders among patients with clinical complaints of obstructive defecation (OD) and their relationship with patients’ expulsive capacity. Patients and methodsRetrospective study of 588 patients with OD studied between 2012 and 2020 with evacuation defecography (ED), and anorectal manometry (ARM) in a subgroup of 294. Results90.3% patients were women, age was 58.5±12.4 years. Most (83.7%) had SDD (43.7% rectocele, 45.3% prolapse, 19.3% enterocele, and 8.5% megarectum), all SDD being more prevalent in women except for megarectum. Functional assessments showed: (a) absence of rectification of anorectal angle in 51% of patients and poor pelvic descent in 31.6% at ED and (b) dyssynergic defecation in 89.9%, hypertonic IAS in 44%, and 33.3% rectal hyposensitivity, at ARM. Overall, 46.4% of patients were categorized as pure SDD, 37.3% a combination of SDD+FDD, and 16.3% as having pure FDD.Rectal emptying was impaired in 66.2% of SDD, 71.3% of FDD and in 78% of patients with both (p=0.017). ConclusionsThere was a high prevalence of SDD in middle-aged women with complaints of OD. Incomplete rectal emptying was more prevalent in FDD than in SDD although FDD and SDD frequently coexist. We recommend a stepwise therapeutic approach always starting with therapy directed to improve FDD and relaxation of striated pelvic floor muscles.

Low anterior resection syndrome phenotypes-Different symptom profiles for different patients.

Attention is increasingly being turned to functional outcomes as being central to colorectal cancer (CRC) survivorship. The current literature may underestimate the impact of evacuatory dysfunction on patient satisfaction with bowel function after anterior resection (AR) for CRC. The aim of this study was to investigate the impact of post-AR symptoms of storage and evacuatory dysfunction on patient satisfaction and health-related quality of life (HRQoL). A cross-sectional study was performed at an Australian hospital of patients post-AR for CRC (2012-2021). The postoperative bowel function scores used were: low anterior resection syndrome (LARS), St Mark's incontinence, Cleveland Clinic constipation and Altomare obstructive defaecation syndrome scores. Eight 'storage' and 'evacuatory' dysfunction symptoms were derived. A seven-point Likert scale measured patient satisfaction. The SF36v2® measured HRQoL. Linear regression assessed the association between symptoms, patient satisfaction and HRQoL. Overall, 248 patients participated (mean age 70.8 years, 57.3% male), comprising 103 with rectal cancer and 145 with sigmoid cancer. Of the symptoms that had a negative impact on patient satisfaction, six reflected evacuatory dysfunction, namely excessive straining (p < 0.001), one or more unsuccessful bowel movement attempt(s)/24 h (p < 0.001), anal/vaginal digitation (p = 0.005), regular enema use (p = 0.004), toilet revisiting (p = 0.004) and >10 min toileting (p = 0.004), and four reflected storage dysfunction, namely leaking flatus (p = 0.002), faecal urgency (p = 0.005), use of antidiarrhoeal medication (p = 0.001) and incontinence-related lifestyle alterations (p < 0.001). A total of 130 patients (53.5%) had 'no LARS', 56 (23.1%) had 'minor LARS' and 57 (23.4%) had 'major LARS'. Fifty-seven (44.5%) patients classified as having 'no LARS' had evacuatory dysfunction. Postoperative storage and evacuatory dysfunction symptoms have an adverse impact on patient satisfaction and HRQoL post-AR. The importance of comprehensively documenting symptoms of evacuatory dysfunction is highlighted. Further research is required to develop a patient satisfaction-weighted LARS-specific HRQoL instrument.

A brief physiology and pathophysiology of the anorectum based on the Integral Theory paradigm.

The remit of this review is confined to the experimental scientific works and surgeries based on the Integral Theory paradigm. The video abstract summarizes the anorectal function, how ligaments cause dysfunction and cure of fecal incontinence and obstructed defecation by ligament repair. Anorectal function is reflex and binary, with cortical and peripheral components. The same three oppositely acting reflex muscle forces which open and close the bladder, contract against the pubourethral (PUL) and uterosacral (USL) ligaments: (I) to close the anorectum for continence when the puborectalis muscle (PRM) contracts forwards; (II) to open the anorectum prior to evacuation when the PRM relaxes; (III) to stretch the rectum in opposite directions to support the anorectal stretch receptors "N" to prevent premature activation of the defecation reflex, (fecal urgency). Weak or loose PULs or USLs may cause dysfunction of closure, of evacuation, and inability to control the defecation reflex (fecal urgency). Repair of the PUL and USL can improve or cure these dysfunctions. The perineal body (PB) acts as an anatomical support for the distal vagina, anorectum and external anal sphincter (EAS). It serves as an anchoring point for the forward action of the pubococcygeus muscle (PCM), which tensions the anterior rectal wall during closure and defecation. Bladder and bowel dysfunction have a similar pathogenesis, ligament laxity, mainly pubourethral and uterosacral, with added PB damage for anorectal dysfunction. PB damage can cause obstructive defecation and descending perineal syndrome (DPS). Repair of damaged PUL and USL can restore the closure and evacuation functions of both bladder an anorectum. DPS can be cured by repair of the PB's suspensory ligaments, deep transversus perinei.

Descending perineal syndrome cure by deep transversus perinei ligament repair: surgical options.

Descending perineal syndrome (DPS) was described by Parks et al. as descent of the anus on straining, typically 3-4 cm below a line drawn from the coccyx to the lower end of the. DPS is associated with obstructed defecation, with increased bulging of the perineum with straining, although perineal descent can also be seen at rest. In their review, Chaudhry and Tarnay stated: "It is controversial whether surgical management is even an option for patients with DPS". The deep transversus perinei (DTP) ligaments are the suspensory ligaments of the perineal body (PB). DTP are approximately 4 cm long. They attach behind the upper 2/3 and lower 1/3 of the descending ramus. If, at childbirth, the PB is overstretched and displaced laterally and inferiorly, the DTP lengthens. DPS is described as descent of the anus on straining, typically 3-4 cm below a line drawn from the coccyx to the lower end of the symphysis. DPS is associated with obstructed and often, assisted defecation, with increased bulging of the perineum with straining descent of the anus on straining. The surgical methodology begins as a standard PB repair which dissects the rectum from the vagina and PB and approximates the displaced components of the PB. We added an additional step: identifying the DTPs, shortening and reinforcing them with the Tissue Fixation System (TFS) minisling or No. 2 polyester sutures. High cure rates for obstructed defecation were achieved with the TFS minisling, and initial results using No. 2 polyester sutures are favourable. The key messages from both operations is DPS is caused by stretching and elongation of DPS ligaments, and these are surgically repairable.

Results of medical treatment with psyllium, lactobacillus, and tryptophan (Plurilac® Trio) in obstructive defecation syndrome.

The term "obstructive defecation syndrome" (ODS) describes a complex condition characterized by defecatory disorders. Such a condition represents a significant proportion of patients, which is estimated to be up to 30% of patients affected by chronic constipation. Presently, a broad agreement has been reached on diagnostic studies, whereas the choice of treatment that aims to improve the quality of life and/or correct the prevalent abnormalities or all anatomical abnormalities remains controversial. This was a retrospective cohort study on 174 patients out of a total of 232 with ODS who were observed in a specialized university unit of surgical coloproctology between 2018 and 2022. Clinical assessment included examining the values of the Agachan-Wexner constipation score and Patient Assessment of Constipation (PAC)-quality of life (QoL) scores, a full digital anorectal examination, anoscopy, RX defecography, and a urogynecological consultation; a functional anorectal test, an endoanal ultrasound, and colonoscopy were performed in select patients. The patients were reevaluated after an 8-10-week course of medical treatment based on a high-fiber diet and fluid intake and 6 g of psyllium combined with lactobacillus and tryptophan b.i.d. The results were analyzed by means of the Wilcoxon rank-sum test, comparing pretreatment scores with the results at the first follow-up visit. After 8-10 weeks of conservative treatment, 128 patients declared full satisfaction, 29 reported moderate satisfaction, and 17 (9.7%) declared no improvement. Among these 17, there were 5 patients with paradoxical puborectal contractions. The value of the Agachan-Wexner constipation score after treatment decreased from the pretreatment Agachan-Wexner constipation score mean value of 23.4 ± 3.7 (mean ± SD range 15-27) to a mean value of 5.3 ± 0.7 (range 3-8, p < 0.001). The quality of life improved, as shown by the PAC-QoL score, indicating great improvement in social relationships. Given the benefits of conservative therapies, they represent a cornerstone in the treatment of ODS, a complex disorder. Diet and bulking agents are mandatory forms of treatment prior to making any surgical attempt, also considering the fact that the psychosomatic component of ODS is an essential prerequisite to match patient expectations.
