Comparative Study Meta-Analysis Review
OBJECTIVE
To compare outcomes following totally transanal endorectal pull-through (TTERPT) versus pull-through with any form of laparoscopic assistance (LAPT) for infants with uncomplicated Hirschsprung's disease.
DESIGN
Systematic review and meta-analysis.
SETTING
Five hospitals with a paediatric surgical service.
PARTICIPANTS
405 infants with uncomplicated Hirschsprung's disease.
INTERVENTIONS
TTERPT versus LAPT.
PRIMARY OUTCOMES
mortality, postoperative enterocolitis, faecal incontinence, constipation, unplanned laparotomy or stoma formation, and injury to abdominal viscera.
SECONDARY OUTCOMES
Haemorrhage requiring transfusion of blood products, abscess formation, intestinal obstruction, intestinal ischaemia, enteric fistula formation, urinary incontinence or retention, impotency and duration of procedure.
RESULTS
Five eligible studies comprising 405 patients were identified from 2107 studies. All studies were retrospective case series, with variability in outcome assessment quality and length of follow-up. Operative duration was 50.29 min shorter with TTERPT (95% CI 39.83 to 60.74, p<0.00001). There were no significant differences identified between TTERPT and LAPT for incidence of postoperative enterocolitis (OR=0.78, 95% CI 0.44 to 1.38, p=0.39), faecal incontinence (OR=0.44, 95% CI 0.09 to 2.20, p=0.32) or constipation (OR=0.84, 95% CI 0.32 to 2.17, p=0.71).
CONCLUSIONS
This meta-analysis did not find any evidence to suggest a higher rate of enterocolitis, incontinence or constipation following TTERPT compared with LAPT. Further long-term comparative studies and multicentre data pooling are needed to determine whether a purely transanal approach offers any advantages over a laparoscopically assisted approach to rectosigmoid Hirschsprung's disease.

Meta-Analysis
BACKGROUND
A large proportion of patients with Hirschsprung disease experience persistent obstructive symptoms after corrective surgery. Persistent obstructive symptoms may result in faecal stasis that can develop into Hirschsprung-associated enterocolitis, a potential life-threatening condition. Important treatment to improve faecal passage is internal anal sphincter relaxation using botulinum toxin injections.
AIM
To give an overview of all empirical evidence on the effectiveness of botulinum toxin injections in patients with Hirschsprung disease.
METHODS
A systematic review and meta-analysis was done by searching PubMed, EMBASE and the Cochrane Library, using entry terms related to: (1) Hirschsprung disease; and (2) Botulinum toxin injections. 14 studies representing 278 patients met eligibility criteria. Data that were extracted were proportion of patients with improvement of obstructive symptoms or less enterocolitis after injection, proportion of patients with adverse effects and data on type botulinum toxin, mean dose, average age at first injection and patients with associated syndromes. Random-effects meta-analysis was used to aggregate effects and random-effects meta-regression was used to test for possible confounding factors.
RESULTS
Botulinum toxin injections are effective in treating obstructive symptoms in on average 66% of patients [event rate (ER) = 0.66, = 0.004, = 49.5, = 278 patients]. Type of botulinum toxin, average dose, average age at first injections and proportion of patients with associated syndromes were not predictive for this effect. Mean 7 duration of improvement after one botulinum toxin injections was 6.4 mo and patients needed on average 2.6 procedures. There was a significant higher response rate within one month after botulinum toxin injections compared to more than one month after Botulinum toxin injections (ER = 0.79, ER = 0.46, Q = 19.37, < 0.001). Botulinum toxin injections were not effective in treating enterocolitis (ER 0.58, = 0.65, = 71.0, = 52 patients). There were adverse effects in on average 17% of patients (ER = 0.17, < 0.001, = 52.1, = 187 patients), varying from temporary incontinence to mild anal pain.
CONCLUSION
Findings from this systematic review and meta-analysis indicate that botulinum toxin injections are effective in treating obstructive symptoms and that adverse effects were present, but mild and temporary.

Meta-Analysis Review
BACKGROUND
Anastomotic leakage is a serious complication that can occur after anterior resection of the rectum. There is a question regarding whether the placement of a transanal tube can decrease the rate of anastomotic leakage. The aim of this systematic review and meta-analysis was to evaluate the efficacy of transanal tube placement after anterior resection.
METHODS
We searched three major databases (PubMed, Embase, and the Cochrane Library) up until January 2015 for studies evaluating the benefit of transanal tubes after anterior resection for rectal cancer. The primary outcome measure was the rate of clinical anastomotic leakage. Secondary outcome was the rate of reoperation. Pooled risk ratios (RR) with 95% confidence intervals (CI) were obtained using random effects models.
RESULTS
One randomized controlled trial and three observational studies involving 909 patients met inclusion criteria. Clinical anastomotic leakage occurred in 3.49% (14 of 401) of patients with transanal tubes and 12.01% (61 of 508) of patients without transanal tubes. Meta-analysis of the studies showed a lower risk of anastomotic leakage (RR, 0.32; 95% CI 0.18-0.58) and reoperation related to leakage (RR, 0.19; 95% CI 0.08-0.46) when the transanal tube was placed.
CONCLUSIONS
While studies are few and mostly observational, the data to date indicate that placement of a transanal tube decreases the rate of clinical anastomotic leakage and reoperation related to leakage. More studies are needed to confirm these findings.

Review
This systematic review investigates the potential of circulating tumour DNA (ctDNA) as a predictive biomarker in the management and prognosis of squamous cell carcinoma of the anal canal (SCCA). PubMed, EMBASE, and Cochrane Central Registry of Controlled Trials were searched until 7 January 2024. Selection criteria included research articles exploring ctDNA in the context of anal cancer treatment response, recurrence risk assessment, and consideration of salvage surgery. A total of eight studies were therefore included in the final review, examining a total of 628 patients. These studies focused on three main themes: SCCA diagnosis and staging, treatment response, and patient outcomes. Significant heterogeneity was observed in terms of patient cohort, study methodology, and ctDNA biomarkers. Four studies provided information on the sensitivity of ctDNA biomarkers in SCCA, with a range of 82-100%. Seven studies noted a correlation between pre-treatment ctDNA levels and SCCA disease burden, suggesting that ctDNA could play a role as a biomarker for the staging of SCCA. Across all seven studies with paired pre- and post-treatment ctDNA samples, a trend was seen towards decreasing ctDNA levels post-treatment, with specific identification of a 'fast elimination' group who achieve undetectable ctDNA levels prior to the end of treatment and may be less likely to experience treatment failure. Residual ctDNA detection post-treatment was associated with poorer patient prognosis. This systematic review identifies the broad potential of ctDNA as a useful and decisive tool in the management of SCCA. Further analysis of ctDNA biomarkers that include larger patient cohorts is required in order to clearly evaluate their potential role in clinical decision-making processes.

Meta-Analysis Review
BACKGROUND
Restorative proctocolectomy with ileal pouch anal anastomosis (IPAA) is considered the procedure of choice in patients with ulcerative colitis (UC) refractory to medical therapy. The incidence of pouchitis is 40% at 5 years. Ten to 15% of patients with pouchitis experience chronic pouchitis.
AIM
To determine the efficacy of medical therapies for the treatment of chronic refractory pouchitis in patients undergoing IPAA for UC.
METHODS
A systematic computer-assisted search of the on-line bibliographic database MEDLINE and EMBASE was performed between 1966 and February 2016. All original studies reporting remission rates following medical treatment for chronic pouchitis were included. All study designs were considered. Remission was defined according to the individual study. Remission endpoints ranged from 15 days to 10 weeks. Chronic pouchitis was defined by each study.
RESULTS
Twenty-one papers were considered eligible. Results from all studies combined suggested that overall remission was obtained in 59% of patients (95% CI: 44-73%). Antibiotics significantly induced remission in patients with chronic pouchitis with 74% remission rate (95% CI:56-93%), (P < 0.001). Biologics significantly induced remission in patients with chronic pouchitis with 53% remission rate (95% CI:30-76%), (P < 0.001). Steroids, bismuth, elemental diet and tacrolimus all can induce remission but failed to achieve significance. Faecal microbiota transplantation in a single study was not found to achieve remission.
CONCLUSIONS
Treatment of chronic refractory pouchitis remains difficult and is largely empirical. Larger randomised controlled trials will help aid the management of chronic pouchitis.

Group A Streptococcus has been associated with a perianal infection. We conducted a systematic review of the literature on childhood streptococcal perianitis in three databases: Excerpta Medica, National Library of Medicine, and Web of Science. The main purposes were to document the clinical features, the tendency to recur, the association with an asymptomatic streptococcal throat carriage, the accuracy of rapid streptococcal tests, and the mechanism possibly underlying the acquisition of this infection. More than 80% of cases are boys ≤7.0 years of age with defecation disorders, perianal pain, local itch, rectal bleeding, or fissure and a sharply demarcated perianal redness. Perianitis is associated with a streptococcal tonsillopharyngitis in about every fifth case. The time to diagnosis is ≥3 weeks in 65% of cases. Recurrences occur within 3½ months in about 20% of cases. An asymptomatic group A streptococcal throat carriage occurs in 63% of cases. As compared with perianal Streptococcus A culture, the rapid streptococcal tests have a positive predictive value of 80% and a negative predictive value of 96%. It is hypothesized that digital inoculation from nasopharynx to anus underlies perianitis. Many cases are likely caused directly by children, who are throat and nasal carriers of Streptococcus A. Some cases might occur in children, who have their bottoms wiped by caregivers with streptococcal tonsillopharyngitis or carriage of Streptococcus.Conclusion: Perianitis is an infection with a distinctive presentation and a rather long time to diagnosis. There is a need for a wider awareness of this condition among healthcare professionals. What is Known: • Group A Streptococcus may cause perianitis in childhood. • Systemic antimicrobials (penicillin V, amoxycillin, or cefuroxime) are superior to topical treatment. What is New: • The clinical presentation is distinctive (defecation disorders, perianal pain, local itch, rectal bleeding, or fissure and a sharply demarcated perianal redness). • The time to diagnosis is usually ≥3 weeks. Recurrences occur in about 20% of cases.

Review
PURPOSE
Pudendal neuropathy is an uncommon condition that exhibits several symptoms depending on the site of nerve entrapment. This study aims to evaluate the efficacy of pudendal nerve neurolysis (PNN) in improving lower urinary tract symptoms, anal and/or urinary incontinence, and sexual dysfunctions.
MATERIALS AND METHODS
A systematic literature search was performed on 20 May 2023 using Scopus, PubMed, and Embase. Only English and adult papers were included. Meeting abstracts and preclinical studies were excluded.
RESULTS
Twenty-one papers were accepted, revealing significant findings in the field. The study identified four primary sites of pudendal nerve entrapment (PNE), with the most prevalent location likely being at the level of the Alcock canal. Voiding symptoms are commonly exhibited in patients with PNE. PNN improved both urgency and voiding symptoms, and urinary and anal incontinence but is less effective in cases of long-standing entrapment. Regarding sexual function, the recovery of the somatic afferent pathway results in an improvement in erectile function early after neurolysis. Complete relief of persistent genital arousal disorder occurs in women, although bilateral PNN is necessary to achieve the efficacy. PNN is associated with low-grade complications.
CONCLUSIONS
PNN emerges as a viable option for addressing urinary symptoms, fecal incontinence, erectile dysfunction, and female sexual arousal in patients suffering from PNE with minimal postoperative morbidity.

Review
INTRODUCTION
Ligation of the intersphincteric fistula tract (LIFT) is a sphincter-preserving procedure for treatment of anal fistulas described in 2007 by Rojanasakul et al. Several studies have since then assessed the procedure with varied results. This review assesses the relevant literature on this topic.
METHODS
The primary endpoints were healing rates, length of follow-up, time to recurrence and post-operative complications. The secondary endpoints were details of the operative technique. A search was made in the PubMed and Embase electronic databases. Reports where LIFT was combined with other fistula treatment techniques were excluded. Only reports in English were included. Most reports were case studies with no control groups. One report could not be retrieved.
RESULTS
A total of 19 original reports were assessed. Details concerning preoperative assessment, antibiotic usage and tract ligation methods varied considerably. Primary healing was achieved in 432 out of 612 (70.6%) patients, and no sphincter function impairments were reported. However, ten out of 19 reports did not include an objective assessment of pre- and post-operative continence. No apparent correlation between length of follow-up and healing rate was found, and the longest time to recurrence was eight months.
CONCLUSION
LIFT is a safe procedure that provided a mean healing of 70.6% with no reports of impairment of the sphincter function. Future reports should include a follow-up length of a minimum of eight months. It remains uncertain whether the outcome may be improved by prior seton suture insertion.

Review
Conversations for providers caring for patients with rectal cancer: Comparison of long-term patient-centered outcomes for patients with low rectal cancer facing ostomy or sphincter-sparing surgery.
For some patients with low rectal cancer, ostomy (with elimination into a pouch) may be the only realistic surgical option. However, some patients have a choice between ostomy and sphincter-sparing surgery. Sphincter-sparing surgery has been preferred over ostomy because it offers preservation of normal bowel function. However, this surgery can cause incontinence and bowel dysfunction. Increasingly, it has become evident that certain patients who are eligible for sphincter-sparing surgery may not be well served by the surgery, and construction of an ostomy may be better. No validated assessment tool or decision aid has been published to help newly diagnosed patients decide between the two surgeries or to help physicians elicit long-term surgical outcomes. Furthermore, comparison of long-term outcomes and late effects after the two surgeries has not been synthesized. Therefore, this systematic review summarizes controlled studies that compared long-term survivorship outcomes between these two surgical groups. The goals are: 1) to improve understanding and shared decision-making among surgeons, oncologists, primary care providers, patients, and caregivers; 2) to increase the patient's participation in the decision; 3) to alert the primary care provider to patient challenges that could be addressed by provider attention and intervention; and 4) ultimately, to improve patients' long-term quality of life. This report includes discussion points for health care providers to use with their patients during initial discussions of ostomy and sphincter-sparing surgery as well as questions to ask during follow-up examinations to ascertain any long-term challenges facing the patient.

Review
BACKGROUND
Perineal damage occurs frequently during childbirth, with severe damage involving injury to the anal sphincter reported in up to 18% of vaginal births. Women who have sustained anal sphincter damage are more likely to suffer perineal pain, dyspareunia (painful sexual intercourse), defaecatory dysfunction, and urinary and faecal incontinence compared to those without damage. Interventions in a subsequent pregnancy may be beneficial in reducing the risk of further severe trauma and may reduce the risk of associated morbidities.
OBJECTIVES
To examine the effects of Interventions for women in subsequent pregnancies following obstetric anal sphincter injury for improving health.
SEARCH METHODS
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2014).
SELECTION CRITERIA
Randomised controlled trials, cluster-randomised trials and multi-arm trials assessing the effects of any intervention in subsequent pregnancies following obstetric anal sphincter injury to improve health. Quasi-randomised controlled trials and cross-over trials were not eligible for inclusion.
DATA COLLECTION AND ANALYSIS
No trials were included. In future updates of this review, at least two review authors will extract data and assess the risk of bias of included studies.
MAIN RESULTS
No eligible completed trials were identified. One ongoing trial was identified.
AUTHORS' CONCLUSIONS
No relevant trials were included. The effectiveness of interventions for women in subsequent pregnancies following obstetric anal sphincter injury for improving health is therefore unknown. Randomised trials to assess the relative effects of interventions are required before clear practice recommendations can be made.
