Low Anterior Resection Syndrome. Anatomical Changes after Anterior Rectal Resection.

In this editorial, the authors bring to the attention of surgeons a personal point of view with the intention of offering a series of anatomical arguments to explain the high rate of functional complications following ultralow rectal resections, resections dominated by faecal incontinence of various intensities. Having as a starting point the anatomy of the pelvic floor and the posterior perineum, the authors are concerned with the functional outcomes of the sphincter-saving anterior rectal resection, regarding the low and ultralow resection. Technically, a conservative surgery for low rectal cancer has been currently performed. If 25 years ago the abdominoperineal resection was the gold standard for rectal cancer located under 7cm from the anal verge, nowadays the preservation of the anal canal as a partner for colon anastomosis has been accomplished. Progressively, from a desire to preserve the normal passage of stool into the anal canal, as anatomically and physiologically as possible, the distal limit of resection was lowered to 2-4 cm from the anal verge and ultra-low anastomoses were created, within the anal sphincter complex. The stated goal: keep the oncological safety standard and, at the same time, avoid definitive colostomy. Starting from the normal anatomy of the pelvic floor and the anorectal segment, the authors take a look at the alterations of the visceral, muscular, and nerve structures as a consequence of the low anterior resection and, particularly, the ultralow anterior resection. A significant degree of functional outcomes regarding defecation, with the onset of marked disabilities of anal continence, the major consequence being anal incontinence (30-70%), have been noticed. The authors go under review for the main anatomical and physiological changes that accompany anterior rectal resection. Conclusions: Thus, the following questions arise: what is the lower limit of resection to avoid total fecal incontinence? Is total incontinence a greater handicap than colostomy or is it not? The answers cannot be supported by solid arguments at this time, but the need to initiate future studies dedicated to this problem emerges.

Patient tolerance and complication rates of transperineal prostate biopsy with coaxial technique under local anesthesia: initial experience of a single institution.

OBJECTIVE: Due to infectious complications of transrectal prostate biopsy (TRBx), the transperineal prostate biopsy (TPBx) technique is gaining popularity and is the first-line method in many institutions. We share our experience of the first 100 patients with TPBx, performed using the coaxial needle technique under local anesthesia. PATIENTS AND METHODS: We retrospectively reviewed the records of the first 100 patients who had undergone TPBx between December 2022 and September 2023. Complication rates, cancer detection rates, patient tolerance, and pain response to the TPBx under local anesthesia at different steps of the procedure were collected. RESULTS: The mean age, total prostate-specific antigen (PSA), prostate volume, and PSA density were 64.5±7.5 years, 8.82±12 ng/mL, 58.4±26.4 mL, and 0.17±0.18 ng/mL2. Prostate cancer (PCa) was detected at histopathological evaluation in 51 patients. The mean positive core number and percentage of cancer involvement per core in patients who have PCa were 5.4±3.2 and 68.5±29.1, respectively. The mean pain score during the entire procedure was 2.85±1.48. When the steps are evaluated separately, the mean pain score during the probe placement step, local anesthetic, and sampling steps were 3.35±1.65, 2.54±1.45, and 0.9±0.82, respectively. CONCLUSIONS: Transperineal prostate biopsy with coaxial needle technique under local anesthesia is a well-tolerated procedure with feasible complication rates and patient discomfort.

Overlooked by the obstetric gaze - how women with persistent health problems due to severe perineal trauma experience encounters with healthcare services: a qualitative study.

BACKGROUND: During the first year postpartum, about 25 per cent of Swedish women with severe perineal trauma (SPT), i.e., a third- or fourth-degree perineal laceration at childbirth, are unsatisfied with their healthcare contacts. Further, there is a lack of research on the more long-term experiences of healthcare encounters among women with persistent SPT-related health problems. This study explores how women with self-reported persistent SPT-related health problems experience their contact with healthcare services 18 months to five years after childbirth when the SPT occurred. METHODS: In this descriptive qualitative study, a purposive sample of twelve women with self-reported persistent health problems after SPT were individually interviewed from November 2020 - February 2022. The data was analysed using inductive qualitative content analysis. RESULTS: Our results showed a paradoxical situation for women with persistent health problems due to SPT. They struggled with their traumatised body, but healthcare professionals rejected their health problems as postpartum normalities. This paradox highlighted the women's difficulties in accessing postpartum healthcare, rehabilitation, and sick leave, which left them with neglected healthcare needs, diminished emotional well-being, and loss of financial and social status. Our results indicated that these health problems did not diminish over time. Consequently, the women had to search relentlessly for a 'key person' in healthcare who acknowledged their persistent problems as legitimate to access needed care, rehabilitation, and sick leave, thus feeling empowered. CONCLUSIONS: Our study revealed that women with persistent SPT-related health problems experienced complex health challenges. Additionally, their needs for medical care, rehabilitation, and sick leave were largely neglected. Thus, the study highlights an inequitable provision of SPT-related healthcare services in Sweden, including regional disparities in access to care. Hence, the authors suggest that Swedish national guidelines for SPT-related care need to be developed and implemented, applying a woman-centered approach, to ensure equitable, effective, and accessible healthcare.

Assessment of sexual and body esteem in postpartum women with or without perineal laceration: a cross-sectional study with cultural translation and validation of the Vaginal Changes Sexual and Body Esteem Scale.

Objective: We aimed to translate and determine cultural validity of the Vaginal Changes Sexual and Body Esteem Scale (VSBE) for Brazilian Portuguese language in postpartum women who underwent vaginal delivery with or without perineal laceration and cesarean section. Methods: A cross-sectional study conducted virtually, with online data collection through a survey with 234 postpartum women of 975 that were invited. Clinical, sociodemographic, and psychometric variables from the VSBE questionnaire were analyzed (content validity index, internal consistency, test-retest reliability, construct/structural and discriminant validity). Multivariate analysis was performed to explore associated factors with the presence of perineal laceration. Results: One-hundred fifty-eight women experienced vaginal delivery, of which 24.79% had an intact perineum, 33.33% had perineal laceration, and 9.4% underwent episiotomy; and 76 participants had cesarean sections. Women with perineal laceration were older, presented dyspareunia and previous surgeries than women without perineal laceration (p<0.05). For VSBE, a high internal consistency (Cronbach's α > 0.7) was observed, but it did not correlate with Body Attractiveness Questionnaire and Female Sexual Function Index; however, it correlated with the presence of women sutured for perineal laceration. Moreover, VSBE presented good structural validity with two loading factors after exploratory factor analysis. VSBE also demonstrated discriminant validity between the presence or absence of perineal laceration. The presence of urinary incontinence (UI) (OR=2.716[1.015-4.667];p=0.046) and a higher VSBE total score (OR=1.056[1.037-1.075];p<0.001) were the only factors associated with perineal laceration. Conclusion: Vaginal Changes Sexual and Body Esteem Scale demonstrated appropriate translation and good internal consistency, discriminant/construct validity and reliability. Vaginal Changes Sexual and Body Esteem Scale total score and presence of UI were associated with women that underwent perineal laceration.

Do alpha blockers reduce the risk of urinary retention post-transperineal prostate biopsy? A systematic narrative review.

BACKGROUND: Transperineal Prostate Biopsy (TPB) is a commonly used technique for the diagnosis of prostate cancer due to growing concerns related to infectious complications associated with transrectal ultrasound-guided prostate biopsy (TRUSB). TPB is associated with an infective complication rate of near zero, however, acute urinary retention (AUR) remains the leading complication causing morbidity. Previously in TRUSB, there was weak evidence that alpha-blockers reduce AUR rates, and their usage has been extrapolated to clinical practice with TPB. This review aims to explore if there is an evidence base for using alpha-blockers to prevent AUR following TPB. METHODS: A systematic approach was used to search Ovid Medline and Embase using keywords related to "Transperineal" and "Retention". Articles were then screened by applying inclusion and exclusion criteria to find studies that compared alpha-blocker recipients to no alpha-blocker use in the perioperative period and the subsequent effect on AUR in TPB. RESULTS: 361 records were identified in the initial search to produce 5 studies included in the final review. No randomised controlled trials (RCTs) were identified. One observational study showed a reduction in AUR rate from 12.5% to 5.3% with a single dose of tamsulosin. A previous systematic review of complications associated with prostate biopsy concluded there may be a potential benefit to alpha-blockers given in the TPB perioperative period. Three observational studies demonstrated a harmful effect related to alpha-blocker use; however, this was well explained by their clear limitations. CONCLUSION: Based on this review and the extrapolation from TRUSB data, perioperative alpha-blockers may offer some weak benefits in preventing AUR following TPB. However, there is significant scope and need for an RCT to further develop the evidence base further given the significant gap in the literature and lack of a standard alpha blocker protocol in TPB.

Risk factors for delayed extubation after pediatric perineal anaplasty in patients less than 1 year of age: a retrospective study.

BACKGROUND: Anorectal malformation is a common congenital problem occurring in 1 in 5,000 births and has a spectrum of anatomical presentations, requiring individualized surgical treatments for normal growth. Delayed extubation or reintubation may result in a longer intensive care unit (ICU) stay and hospital stay, increased mortality, prolonged duration of mechanical ventilation, increased tracheostomy rate, and higher hospital costs. Extensive studies have focused on the role of risk factors in early extubation during major infant surgery such as Cardiac surgery, neurosurgery, and liver surgery. However, no study has mentioned the influencing factors of delayed extubation in neonates and infants undergoing angioplasty surgery. MATERIALS AND METHODS: We performed a retrospective study of neonates and infants who underwent anorectal malformation surgery between June 2018 and June 2022. The principal goal of this study was to observe the incidence of delayed extubation in pediatric anorectal malformation surgery. The secondary goals were to identify the factors associated with delayed extubation in these infants. RESULTS: We collected data describing 123 patients who had anorectal malformations from 2019 to 2022. It shows that 74(60.2%) in the normal intubation group and 49(39.8%) in the longer extubation. In the final model, anesthesia methods were independently associated with delayed extubation (P < 0.05). CONCLUSION: We found that the anesthesia method was independently associated with early extubation in neonates and infants who accepted pediatric anorectal malformation surgery.

A novel perineal exposure method in laparoscopic abdominal perineal resection of rectal cancer: a case series study.

BACKGROUND: Abdominal perineal resection (APR) of rectal cancer, also known as Mile's procedure, is a classic procedure for the treatment of rectal cancer. Through the improvement of surgical skills and neoadjuvant therapy, the sphincter-preserving rate in rectal cancer patients has improved, even in patients with ultralow rectal cancer who underwent APR in the past. However, APR cannot be completely replaced by low anterior resection (LAR) in reality. APR still has its indications, when the tumor affects the external sphincter, etc. Good perineal exposure in APR is difficult and can seriously affect surgical safety and the long-term prognosis. METHODS: We reviewed the records of 16 consecutive patients with rectal cancer who underwent APR at Anqing Municipal Hospital from January 2022 to April 2023, including 11 males and 5 females, with an average age of 64.8 ± 10.3 years. The perineal operation was completed with the Lone-Star® retractor-assisted (LSRA) exposure method. After incising the skin and subcutaneous tissue, a Lone-Star® retractor was placed, and the incision was retracted in surrounding directions with 8 small retractors, which facilitated the freeing of deep tissues. We dynamically adjusted the retractor according to the plane to fully expose the surgical field. RESULTS: All 16 patients underwent laparoscopic-assisted APR successfully. Thirteen procedures were performed independently by a single person, and the others were completed by two persons due to intraoperative arterial hemostasis. All specimens were free of perforation and had a negative circumferential resection margin (CRM). Postoperative complications occurred in 4 patients, including urinary retention in 1 patient, pulmonary infection in 1 patient, intestinal adhesion in 1 patient and peristomal dermatitis in 1 patient, and were graded as ClavienDindo grade 3 or lower and cured. No distant metastasis or local recurrence was found for any of the patients in the postoperative follow-up. CONCLUSIONS: The application of the LSRA exposure method might be helpful for perineal exposure during APR for rectal cancer, which could improve intraoperative safety and surgical efficiency, achieve one-person operation, and increase the comfort of operators.

Midwives' approach to the prevention and repair of obstetric perineal trauma in Spain.

AIM: Different clinical practice guidelines include recommendations on how to prevent and repair obstetric perineal trauma, as well as the use of episiotomy. To evaluate the variability in midwives' professional practices for preventing and repairing perineal trauma, as well as the professional factors that may be associated with the restrictive use of episiotomy. DESIGN: Observational cross-sectional study. METHODS: Three hundred five midwives completed an anonymous questionnaire developed by the authors and distributed across various midwifery scientific societies. The main outcomes measured were the frequencies of adopting specific practices related to perineal injury prevention and repair, episiotomy technique and restrictive episiotomy use (<10%). Odds ratios (OR) and adjusted odds ratios (aOR) with 95% confidence intervals were estimated. RESULTS: Intrapartum perineal massage was not normally used by 253 (83%) of midwives, and 186 (61%) applied compresses soaked in warm water to the perineum. Regarding episiotomy, there was a great deal of variability, noting that 129 (42.3%) adopted a restrictive use of this procedure, 125 (41%) performed it between 10% and 20%, while 51 midwives (16.7%) performed it in more than 20% of cases. In addition, 165 (54.1%) midwives followed an incision angle of 60º. Concerning tears, 155 (50.8%) usually sutured first-degree tears and 273 (89.5%) always sutured second-degree tears. Midwives attending home births (aOR = 6.5; 95% CI: 2.69-15.69), working at a teaching hospital (aOR = 3.69; 95% CI: 1.39-9.84), and the ones who recently completed their professional training (aOR = 3.58; 95% CI: 1.46-8.79) were significantly more likely to adopt a restrictive use of episiotomy. CONCLUSIONS: There is a significant variability in Spanish midwives' practices for preventing and repairing perineal tears. Moreover, the restrictive use of episiotomy is associated with midwives attending home births, working in teaching hospitals and having recent professional training. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Perineal Benign Symmetric Lipomatosis in a Female Patient: A Case Report.

BACKGROUND Benign symmetric lipomatosis (BSL), also known as Madelung's disease, is a rare disease generally characterized by fat deposits painlessly and symmetrically distributed in the body. In former studies, the incidence of BSL is highest in male patients and more frequent in the Mediterranean area. Asian females seem to be rarely affected. BSL often occurs in the neck or upper-back of patients, and is related to various metabolic disorders. Unusual clinical appearances may add difficulties in diagnosis. CASE REPORT In this report, we present a case of BSL in a 33-year-old woman's perineal region, with no clear BSL risk factors (sex, medical history, sites, and comorbidities), which increased the difficulties in diagnosis. The patient's quality of life was seriously affected by the continuous growth of fat tissue. Based on MRI and B-ultrasonic examinations, she underwent excision at our outpatient facility. Combined with the patient's clinical appearance, imaging results, and pathological tests, we could finally determine the diagnosis of BSL. After 18 months of follow-up, this patient recovered well with no recurrence. CONCLUSIONS Difficulties in diagnosis can seriously affect doctors' treatment approaches. BSL rarely occurs in the lower body, and our patient showed no clear risk factors. Therefore, imaging and pathological examinations can be essential tools for dermatological and plastic surgeons to diagnose and treat rare BSL.

Treatment techniques for rectovaginal fistulas after low rectal resection for deep endometriosis.

Endometriosis is a benign gynecologic affection that may lead to major surgeries, such as colorectal resections. Rectovaginal fistulas (RVF) are among the possible complications. When they occur, it is necessary to adapt the repair surgery as best as possible to limit their functional consequences. This video shows three different techniques for correcting RVF after rectal resection for endometriosis, with a combination of perineal surgery and laparoscopy: a mucosal flap, a transanal transection and single stapled anastomosis (TTSS) and a pull through.

Perineal Squamous Cell Carcinoma Arising in an Epidermal Cyst.

A 90-year-old Japanese woman who had been aware of a subcutaneous mass on the right perineal region for 5 years was referred to our hospital for further examination and treatment because of the rapid growth of the mass and bleeding that began 3 months earlier. A biopsy of the mass revealed a diagnosis of well-differentiated squamous cell carcinoma. On preoperative examination, the tumor was 90×40 mm in size and was suspected to have partially invaded the levator ani muscle and external sphincter. Since a preoperative cardiac evaluation indicated severe aortic stenosis, we performed transcatheter aortic valve implantation. A radical resection was then performed with general anesthesia. The skin and subcutaneous tissue defects were reconstructed with a posterior gluteal-thigh propeller flap, and a sigmoid colostomy was created. The patient had a good postoperative course and was transferred to a rehabilitation facility 28 days after the surgery. Epidermal cysts are a common benign tumor, and clinicians should keep in mind that these cysts can become malignant.

Anatomic Subtype Differences in Extramammary Paget Disease: A Meta-Analysis.

Importance: Extramammary Paget disease (EMPD) is a rare, highly recurrent cutaneous malignant neoplasm of unclear origin. EMPD arises most commonly on the vulvar and penoscrotal skin. It is not presently known how anatomic subtype of EMPD affects disease presentation and management. Objective: To compare demographic and tumor characteristics and treatment approaches for different EMPD subtypes. Recommendations for diagnosis and treatment are presented. Data Sources: MEDLINE, Embase, Web of Science Core Collection, and Cochrane Reviews CENTRAL from December 1, 1990, to October 24, 2022. Study Selection: Articles were excluded if they were not in English, reported fewer than 3 patients, did not specify information by anatomic subtype, or contained no case-level data. Metastatic cases on presentation were also excluded. Data Extraction and Synthesis: Abstracts of 1295 eligible articles were independently reviewed by 5 coauthors, and 135 articles retained. Reporting was in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. The analysis was cunducted in August 2019 and updated in November 2022. Findings: Most vulvar EMPD cases were asymptomatic, and diagnosis was relatively delayed (mean, 25.1 months). Although most vulvar EMPD cases were intraepidermal (1247/1773 [70.3%]), radical surgeries were still performed in almost one-third of cases. Despite this aggressive surgical approach, 481 of 1423 (34%) recurred, commonly confined to the skin and mucosa (177/198 [89.4%]). By contrast, 152 of 1101 penoscrotal EMPD cases (14%) recurred, but more than one-third of these recurrences were regional or associated with distant metastases (54 of 152 [35.5%]). Perianal EMPD cases recurred in one-third of cases (74/218 [33.9%]), with one-third of these recurrences being regional or associated with distant metastasis (20 of 74 [27.0%]). Perianal EMPD also had the highest rate of invasive disease (50% of cases). Conclusions and Relevance: The diagnosis and treatment of EMPD should differ based on anatomic subtypes. Considerations for updated practice may include less morbid treatments for vulvar EMPD, which is primarily epidermal, and close surveillance for local recurrence in vulvar EMPD and metastatic recurrence in perianal EMPD. Recurrences in penoscrotal subtype were less common, and selective surveillance in this subtype may be considered. Limitations of this study include the lack of replication cohorts and the exclusion of studies that did not stratify outcomes by anatomic subtype.

Evaluation of perineal wound healing and pain outcomes after low-angle mediolateral episiotomy in women undergoing vaginal childbirth: A systematic review and meta-analysis.

The efficacy of episiotomy, particularly the angle of incision in mediolateral episiotomies, remains a significant area of inquiry in obstetrics. This meta-analysis aimed to evaluate the impact of low-angle mediolateral episiotomy on perineal wound healing and pain outcomes in women undergoing vaginal childbirth. Adhering to PRISMA guidelines, a systematic review was conducted using the PICO framework. Studies were selected based on predefined inclusion and exclusion criteria, focusing on randomised controlled trials (RCTs) involving low-angle mediolateral episiotomies. Comprehensive literature searches were performed across major electronic databases including PubMed, Embase, Web of Science and Cochrane Library. Data extraction and quality assessments were meticulously carried out by independent reviewers, employing the Cochrane Collaboration's risk of bias tool. A total of 1246 articles were initially identified, with 8 articles meeting the strict inclusion criteria for the final analysis. The meta-analysis revealed significant heterogeneity among studies regarding postoperative pain (p < 0.0001, I2 = 77.5%), and employed a random-effects model. Results showed that low-angle episiotomies significantly reduced postoperative pain (OR = 0.27, 95% CI: 0.17-0.42, p < 0.001), and increased first-degree healing rates (OR = 2.95, 95% CI: 2.20-3.96, p < 0.001) compared to traditional angles. Sensitivity analyses confirmed the stability of these findings, and no significant publication bias was detected. The analysis suggests that low-angle episiotomies can potentially reduce postoperative perineal pain and enhance wound healing. However, the limited number and varying quality of the included studies warrant cautious interpretation of these results. Further well-designed studies are needed to corroborate these findings and guide clinical practice.

The REPAIR study: oral antibiotics to prevent infection and wound dehiscence after obstetric perineal tear-a double-blinded placebo controlled randomized trial.

BACKGROUND: Approximately 85% of women experience an obstetric tear at delivery and up to 25% subsequently experience wound dehiscence and/or infection. Previous publications suggest that intravenous antibiotics administrated during delivery reduces this risk. We do not know if oral antibiotics given after delivery can reduce the risk of wound dehiscence or infection. Our aim is to investigate whether three doses of oral antibiotics (amoxicillin 500 mg/clavulanic acid 125 mg) given after delivery can reduce the risk of wound dehiscence and infection in patients with a second-degree obstetric tear or episiotomy. METHODS: We will perform a randomized, controlled, double-blinded study including 221women in each arm with allocation 1:1 in relation to the randomization. The study is carried out at Department of Obstetrics & Gynecology, Herlev University Hospital, Copenhagen, Denmark. The women will be included after delivery if they have had a second-degree tear or episiotomy. After inclusion, the women will have a clinical follow-up visit after 1 week. The tear and healing will be evaluated regarding signs of infection and/or dehiscence. The women will again be invited for a 1-year clinical examination including ultrasound. Questionnaires exploring symptoms related to the obstetric tear and possible complications will be answered at both visits. Our primary outcome is wound dehiscence and/or wound infection, which will be calculated using χ2 tests to compare groups. Secondary outcomes are variables that relate to wound healing, as pain, use of painkillers and antibiotics, need for further follow-up, as well as outcomes that may be related to the birth or healing process, urinary or anal incontinence, symptoms of prolapse, female body image, and sexual problems. DISCUSSION: Reducing the risk of wound dehiscence and/or infection would decrease the number of control visits, prevent the need for longer antibiotic treatment, and possibly also decrease both short-term and long-term symptoms. This would be of great importance so the mother, her partner, and the baby could establish and optimize their initial family relation. TRIAL REGISTRATION: The conduction of this study is approved the 2/2-2023 with the EU-CT number: 2022-501930-49-00. CLINICALTRIALS: gov Identifier: NCT05830162.
