Wang C, Huang T, Wang X. Efficacy and safety of transanal opening of intersphincteric space in the treatment of high complex anal fistula: A meta‑analysis. Exp Ther Med 2024; 28:306. [PMID: 38873039 PMCID: PMC11170326 DOI: 10.3892/etm.2024.12595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 05/01/2024] [Indexed: 06/15/2024] Open
Abstract
The best treatment of high complex anal fistula (HCAF) is to avoid anal incontinence while improving the cure rate. On this basis, several surgical procedures for preserving the anal sphincter have been proposed. The purpose of the present study was to evaluate the efficacy and safety of transanal opening of intersphincteric space for treating HCAF. PubMed, Cochrane Library, China National Knowledge Infrastructure and the Wanfang databases were searched to collate all the articles on transanal opening of intersphincteric space for treating HCAF. A total of two researchers independently completed the whole process, from screening and inclusion to data extraction and the data was included in the RevMan 5.3 software for analysis. The main outcomes included the patients' essential characteristics, primary healing rate, management after recurrence, final healing rate, anal incontinence score before and after surgery, postoperative complication rate and types of complications. A total of six articles were included in this meta-analysis. The results showed that the weighted final healing rate of patients following transanal opening of intersphincteric space was 89% [risk differences (RD)=0.89; 95% confidence interval (CI)=0.86-0.92; I2=0%; P<0.00001]. The results of the anal incontinence score showed that there was no significant difference between the results before and after transanal opening of intersphincteric space surgery mean differences [(MD)=-0.04, Cl=-0.10-0.02, I2=0%; P=0.21]. Only 11 patients were reported to have complications, including urinary retention and bleeding following transanal opening of intersphincteric space with a complication rate of 8% (11/138) and the weighted average complication rate was 6% (RD=0.06,95% CI=0.02-0.10; I2=9%; P=0.003). Transanal opening of intersphincteric space has a high cure rate, a favorable anal incontinence score, fewer types of postoperative complications and a low complication rate; it can be used as a minimally invasive and sphincter-preserving surgical method for treating HCAF and is worthy of further promotion and research in clinical practice.

[PMID: 38848350 PMCID: PMC11161075 DOI: 10.1371/journal.pone.0304473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 05/13/2024] [Indexed: 06/09/2024] Open
Abstract
PURPOSE We performed a meta-analysis to identify risk factors affecting spinal fusion. METHODS We systematically searched PubMed, Embase, and the Cochrane Library from inception to January 6, 2023, for articles that report risk factors affecting spinal fusion. The pooled odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using fixed-effects models for each factor for which the interstudy heterogeneity I2 was < 50%, while random-effects models were used when the interstudy heterogeneity I2 was ≥ 50%. Using sample size, Egger's P value, and heterogeneity across studies as criteria, we categorized the quality of evidence from observational studies as high-quality (Class I), moderate-quality (Class II or III), or low-quality (Class IV). Furthermore, the trim-and-fill procedure and leave-one-out protocol were conducted to investigate potential sources of heterogeneity and verify result stability. RESULTS Of the 1,257 citations screened, 39 unique cohort studies comprising 7,145 patients were included in the data synthesis. High-quality (Class I) evidence showed that patients with a smoking habit (OR, 1.57; 95% CI, 1.11 to 2.21) and without the use of bone morphogenetic protein-2 (BMP-2) (OR, 4.42; 95% CI, 3.33 to 5.86) were at higher risk for fusion failure. Moderate-quality (Class II or III) evidence showed that fusion failure was significantly associated with vitamin D deficiency (OR, 2.46; 95% CI, 1.24 to 4.90), diabetes (OR, 3.42; 95% CI, 1.59 to 7.36), allograft (OR, 1.82; 95% CI, 1.11 to 2.96), conventional pedicle screw (CPS) fixation (OR, 4.77; 95% CI, 2.23 to 10.20) and posterolateral fusion (OR, 3.63; 95% CI, 1.25 to 10.49). CONCLUSIONS Conspicuous risk factors affecting spinal fusion include three patient-related risk factors (smoking, vitamin D deficiency, and diabetes) and four surgery-related risk factors (without the use of BMP-2, allograft, CPS fixation, and posterolateral fusion). These findings may help clinicians strengthen awareness for early intervention in patients at high risk of developing fusion failure.

[PMID: 38699024 PMCID: PMC11064137 DOI: 10.1016/j.heliyon.2024.e29809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 03/23/2024] [Accepted: 04/15/2024] [Indexed: 05/05/2024] Open
Abstract
Anal fistula is a common anal and intestinal disease. The wound of anal fistula surgery is open and polluting, which is the most difficult to heal among all surgical incisions. To investigate the mechanism of Huanglian ointment (HLO) on wound healing after anal fistula incision. The S. aureus infected wound in SD rats were used to imitate poor healing wound after anal fistula surgery. SD rats with wound sites (n = 24) were randomly divided into four groups (Control group, Model group, Potassium permanganate (PP) treatment group, and HLO treatment group). The wound healing rate was evaluated, HE staining was used to evaluate the pathological changes of each group, ELISA was used to detect the secretion of inflammatory factors in each group, and the mechanism was explored through metabolomics and proteomics in plasma rat. Compared to other groups, the rate of wound healing in the HLO group was higher on days 7 and 14. Histological analysis showed that collagen and fibroblast in HLO rats were significantly increased, inflammatory cells were reduced, and vascular endothelial permeability was increased. ELISA results showed that the secretion of inflammatory factors in HLO rats was significantly lower. Significant proteins and metabolites were identified in the wound tissues of the infected rats and HLO-treated rats, which were mainly attributed to Cdc42, Ctnnb1, Actr2, Actr3, Arpc1b, Itgam, Itgb2, Cttn, Linoleic acid metabolism, d-Glutamine and d-glutamate metabolism, Phenylalanine, tyrosine and tryptophan biosynthesis, Phenylalanine metabolism, alpha-Linolenic acid metabolism, and Ascorbate and aldarate metabolism. In conclusion, this study showed that HLO can promote S. aureus infected wound healing, and the data provide a theoretical basis for the treatment of wounds after anal fistula surgery with HLO.

Tian Y, Wang Y, Wen N, Wang S, Li B, Liu G. Prognostic factors associated with early recurrence following liver resection for colorectal liver metastases: a systematic review and meta-analysis. BMC Cancer 2024; 24:426. [PMID: 38584263 PMCID: PMC11000331 DOI: 10.1186/s12885-024-12162-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Accepted: 03/21/2024] [Indexed: 04/09/2024] Open
Abstract
BACKGROUND Colorectal cancer (CRC) is the 3rd most common malignancy with the liver being the most common site of metastases. The recurrence rate of colorectal liver metastases (CRLM) after liver resection (LR) is notably high, with an estimated 40% of patients experiencing recurrence within 6 months. In this context, we conducted a meta-analysis to synthesize and evaluate the reliability of evidence pertaining to prognostic factors associated with early recurrence (ER) in CRLM following LR. METHODS Systematic searches were conducted from the inception of databases to July 14, 2023, to identify studies reporting prognostic factors associated with ER. The Quality in Prognostic Factor Studies (QUIPS) tool was employed to assess risk-of-bias for included studies. Meta-analysis was then performed on these prognostic factors, summarized by forest plots. The grading of evidence was based on sample size, heterogeneity, and Egger's P value. RESULTS The study included 24 investigations, comprising 12705 individuals, during an accrual period that extended from 2007 to 2023. In the evaluation of risk-of-bias, 22 studies were rated as low/moderate risk, while two studies were excluded because of high risk. Most of the studies used a postoperative interval of 6 months to define ER, with 30.2% (95% confidence interval [CI], 24.1-36.4%) of the patients experiencing ER following LR. 21 studies were pooled for meta-analysis. High-quality evidence showed that poor differentiation of CRC, larger and bilobar-distributed liver metastases, major hepatectomy, positive surgical margins, and postoperative complications were associated with an elevated risk of ER. Additionally, moderate-quality evidence suggested that elevated levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA199), lymph node metastases (LNM) of CRC, and a higher number of liver metastases were risk factors for ER. CONCLUSION This review has the potential to enhance the efficacy of surveillance strategies, refine prognostic assessments, and guide judicious treatment decisions for CRLM patients with high risk of ER. Additionally, it is essential to undertake well-designed prospective investigations to examine additional prognostic factors and develop salvage therapeutic approaches for ER of CRLM.

Abstract
PURPOSE Surgeons can treat debilitating conditions of uncontrollable complex anorectal fistulas with sepsis, even after repeated fistula surgeries, for curative intention. Adipose-derived stem cells have shown good outcomes for refractory Crohn fistula. Unfortunately, cell therapy has some limitations, including high costs. We have therefore attempted immediate cell-assisted lipotransfer (CAL) in treating refractory complex anal fistulas and observed its outcomes. METHODS In a retrospective study, CAL, using a mixture of freshly extracted autologous stromal vascular fraction (SVF) and fat tissues, was used to treat 22 patients of refractory complex anal fistula from March 2018 to May 2021. Preoperative and postoperative assessments were performed with direct visual inspection, digital palpation, and endoanal ultrasonography. A fistula was considered completely healed if (1) the patient had no symptoms of discharge or inflammation; (2) there were no visible secondary openings of fistula tract inside and outside of the anorectal unit and even in the perineum; and (3) there was no primary opening in the anus. The endpoint of complete remission was wound healing without signs of inflammation 3 months after CAL treatment. RESULTS In a total of 22 patients who received CAL treatment, 19 patients showed complete remission, 1 patient showed partial improvement, and 2 patients showed no improvement. One of the 2 patients without improvement at primary endpoint showed complete remission 9 months after CAL. There were no significant adverse effects of the procedure. CONCLUSION We found that the immediately-collected CAL procedure for refractory complex anal fistula showed good outcomes without adverse side effects. It can be strongly recommended as an alternative surgical option for the treatment of complex anal fistula that is uncontrollable even after repeated surgical procedures. However, considering the unpredictable characteristics of SVF, long-term follow-up is necessary.

[PMID: 38419722 PMCID: PMC10899812 DOI: 10.1093/gastro/goae002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 12/07/2023] [Accepted: 12/22/2023] [Indexed: 03/02/2024] Open
Abstract
Background Accurate preoperative evaluation of fistula-in-ano can guide the choice of surgical procedure and may improve healing rates. This prospective study aimed to evaluate the accuracy of conventional 3D transperineal ultrasound (3D-TPUS) compared with SonoVue (SVE)-enhanced 3D-TPUS for the detection and classification of anal fistula. Methods In this prospective study, 3D-TPUS reconstructions were performed before and after SVE enhancement in 60 patients with fistula-in-ano who intended to undergo surgery at the Department of Anorectal Surgery, Qilu Hospital, Cheeloo College of Medicine, Shandong University (P. R. China) between January 2021 and October 2021. Accuracies of anal fistula classification, complexity classification, detection of anal fistula branches, and detection of internal opening between 3D-TPUS and SVE 3D-TPUS were compared based on a reference standard-intraoperative findings. Results This study enrolled 60 patients (mean age, 37.1 ± 11.4 years; mean follow-up, 9 ± 3 months). Intraoperative findings showed that the fistula type was intersphincteric in 23 patients (38.3%), trans-sphincteric in 35 (58.3%; 12 high and 23 low), and suprasphincteric in 2 (3.3%). Moreover, 68 internal openings were found. Compared with the accuracy of 3D-TPUS, that of SVE 3D-TPUS was similar in fistula classification [95.0% (57/60) vs 96.7% (58/60), P = 0.392], but significantly higher in internal opening evaluation [80.9% (55/68) vs 97.1% (66/68), P = 0.001], complexity classification [85.0% (51/60) vs 98.3% (59/60), P = 0.018], and detection of fistula branches [70.4% (19/27) vs 92.6% (25/27), P = 0.031]. Conclusions SVE 3D-TPUS may be a useful examination for patients with perianal fistulae because of its high accuracy and consistency with intraoperative findings, especially in complex fistula-in-ano and difficult cases.

Abstract
Objectives Postoperative delirium (POD) is considered to be a common complication of spine surgery. Although many studies have reported the risk factors associated with POD, the results remain unclear. Therefore, we performed a meta-analysis to identify risk factors for POD among patients following spinal surgery. Methods We systematically searched the PubMed, Embase and the Cochrane Library for relevant articles published from 2006 to February 1, 2023 that reported risk factors associated with the incidence of POD among patients undergoing spinal surgery. The Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines were followed, and random effects models were used to estimate pooled odds ratio (OR) estimates with 95 % confidence intervals (CIs) for each factor. The evidence from observational studies was classified according to Egger's P value, total sample size, and heterogeneity between studies. Results Of 11,329 citations screened, 50 cohort studies involving 1,182,719 participants met the inclusion criteria. High-quality evidence indicated that POD was associated with hypertension, diabetes mellitus, cardiovascular disease, pulmonary disease, older age (>65 years), patients experiencing substance use disorder (take drug ≥1 month), cerebrovascular disease, kidney disease, neurological disorder, parkinsonism, cervical surgery, surgical site infection, postoperative fever, postoperative urinary tract infection, and admission to the intensive care unit (ICU). Moderate-quality evidence indicated that POD was associated with depression, American Society of Anesthesiologists (ASA) fitness grade (>II), blood transfusion, abnormal potassium, electrolyte disorder, length of stay, inability to ambulate and intravenous fluid volume. Conclusions Conspicuous risk factors for POD were mainly patient- and surgery-related. These findings help clinicians identify high-risk patients with POD following spinal surgery and recognize the importance of early intervention.

European Society of Coloproctology: Guidelines for diagnosis and treatment of cryptoglandular anal fistula. Colorectal Dis 2024; 26:145-196. [PMID: 38050857 DOI: 10.1111/codi.16741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 07/11/2023] [Accepted: 08/03/2023] [Indexed: 12/07/2023]
Abstract
AIM The primary aim of the European Society of Coloproctology (ESCP) Guideline Development Group (GDG) was to produce high-quality, evidence-based guidelines for the management of cryptoglandular anal fistula with input from a multidisciplinary group and using transparent, reproducible methodology. METHODS Previously published methodology in guideline development by the ESCP has been replicated in this project. The guideline development process followed the requirements of the AGREE-S tool kit. Six phases can be identified in the methodology. Phase one sets the scope of the guideline, which addresses the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula in adult patients presenting to secondary care. The target population for this guideline are healthcare practitioners in secondary care and patients interested in understanding the clinical evidence available for various surgical interventions for anal fistula. Phase two involved formulation of the GDG. The GDG consisted of 21 coloproctologists, three research fellows, a radiologist and a methodologist. Stakeholders were chosen for their clinical and academic involvement in the management of anal fistula as well as being representative of the geographical variation among the ESCP membership. Five patients were recruited from patient groups to review the draft guideline. These patients attended two virtual meetings to discuss the evidence and suggest amendments. In phase three, patient/population, intervention, comparison and outcomes questions were formulated by the GDG. The GDG ratified 250 questions and chose 45 for inclusion in the guideline. In phase four, critical and important outcomes were confirmed for inclusion. Important outcomes were pain and wound healing. Critical outcomes were fistula healing, fistula recurrence and incontinence. These outcomes formed part of the inclusion criteria for the literature search. In phase five, a literature search was performed of MEDLINE (Ovid), PubMed, Embase (Ovid) and the Cochrane Database of Systematic Reviews by eight teams of the GDG. Data were extracted and submitted for review by the GDG in a draft guideline. The most recent systematic reviews were prioritized for inclusion. Studies published since the most recent systematic review were included in our analysis by conducting a new meta-analysis using Review manager. In phase six, recommendations were formulated, using grading of recommendations, assessment, development, and evaluations, in three virtual meetings of the GDG. RESULTS In seven sections covering the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula, there are 42 recommendations. CONCLUSION This is an up-to-date international guideline on the management of cryptoglandular anal fistula using methodology prescribed by the AGREE enterprise.

Tech Coloproctol 2023; 28:12. [PMID: 38091125 DOI: 10.1007/s10151-023-02886-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Accepted: 10/21/2023] [Indexed: 12/18/2023]
Abstract
BACKGROUND The use of cutting seton (CS) for the management of cryptoglandular fistula-in-ano has remained controversial because of reports of fecal incontinence, postoperative pain, and extended healing time. The aim of this review was to provide the first synthesis of studies investigating the use of CS for the treatment of cryptoglandular fistula-in-ano. METHODS MEDLINE, Embase, and CENTRAL were searched up to October 2022. Randomized controlled trials and observational studies comparing CS with alternative interventions were included, along with single-arm studies evaluating CS alone. The primary outcome was fistula-in-ano recurrence, and secondary outcomes included incontinence, healing time, proportion with complete healing, and postoperative pain. Inverse variance random-effects meta-analyses were used to pool effect estimates. RESULTS After screening 661 citations, 29 studies were included. Overall, 1513 patients undergoing CS (18.8% female, mean age: 43.1 years) were included. Patients with CS had a 6% (95% CI: 3-12%) risk of recurrence and a 16% (95% CI: 5-38%) risk of incontinence at 6 months. CS patients had an average healing time of 14.6 weeks (95% CI: 10-19 weeks) with 73% (95% CI: 48-89%) of patients achieving complete healing at 6 months postoperatively. There was no difference in recurrence between CS and fistulotomy, advancement flap, two-stage seton fistulotomy, or draining seton. CONCLUSIONS Overall, this analysis shows that CS has comparable recurrence and incontinence rates to other modalities. However, this may be at the expense of more postoperative pain and extended healing time. Further comparative studies between CS and other modalities are warranted.

Abstract
BACKGROUND Anal fistulae are common, predominantly cryptoglandular, and almost invariably require surgical treatment. Recurrences are common for procedures other than fistulotomy regardless of technique and adequacy of repair. Growing evidence supports the pivotal role of specific intestinal bacteria in anastomotic failures after bowel resection. Anal crypts harbor colonic microbiota suggesting that similar mechanisms to anastomotic healing might prevail after anal fistula repair and hence influence healing. This study aims at assessing the potential role of the intestinal microbiome in the clinical outcomes after surgical repair of cryptoglandular anal fistula. METHODS This is a pilot prospective cohort study enrolling patients with anal fistula undergoing endoanal advancement flap. For microbiome analysis, stool samples are taken via rectal swab before the procedure; additionally, a portion of the fistula is collected intraoperatively after fistulectomy. Samples from groups with treatment failure are compared to samples from patients who healed after surgical repair. Alpha and beta diversities and differential abundance of microbial taxa are determined and compared between groups with DADA2 analytical pipeline. RESULTS Five patients have been enrolled to date (one female, four male). At median follow-up of 6 months (2-11), one patient experienced disease recurrence at 3 months. DNA from the 5 rectal swab and tissue samples was extracted, showing increased relative abundance of Enterococcus faecalis in samples from the patient who developed a recurrent fistula but not in those without recurrence. CONCLUSION These very preliminary data suggest that intestinal microbiome may represent a crucial determinant of the surgical outcomes after anal fistula surgery.

Abstract
BACKGROUND the ideal clinical profile of patients or fistula features for fistula laser closure (FiLaC®) technique remain to be established. The aim of this study was to analyze clinical outcomes and the safety profile of FiLaC® in search for an ideal setting for this technique. METHODS a retrospective observational study was performed from a prospective database including all consecutive patients who underwent surgery for anal fistula (AF) with FiLaC® in the coloproctology unit of a tertiary referral center, between October 2015 and December 2021. The FiLaC® procedure was offered to AF patients who were considered to be at risk of fecal incontinence. Fistulas were described according to Parks' classification and categorized as complex or simple according to the American Gastroenterological Association (AGA) guidelines. Healing was defined by the closure of the internal and external openings for at least six months. Predictive factors of AF healing were investigated. RESULTS a total of 36 patients were included, with a mean age of 48 ± 13.9 years. Twenty patients (55.6 %) were male and 13 patients (36 %) had Crohn's disease (CD). Fourteen patients (38.8 %) had a complex fistula. The primary and secondary healing rates were 55.6 % and 91.7 %, respectively, during a median follow-up time of 12 months (IQR 7-29). No fecal continence impairment was registered in any case. The proportion of patients with primary healing was significantly higher in CD patients (76.9 % vs 43.5 %, p = 0.048). CONCLUSIONS FiLaC® is a sphincter-preserving procedure with an excellent safety profile and reasonable success rate despite of the strict patient selection. This technique may be attractive for patients with CD due to its higher primary healing rate.

Video Capsule Endoscopy can Identify Occult Luminal Crohn's Disease in Patients with Isolated Perianal Fistulas. J Crohns Colitis 2023; 17:1624-1630.

Abstract
BACKGROUND Accurate tools to distinguish Crohn's disease [CD] from cryptoglandular disease in patients with perianal fistulas without detectable luminal inflammation on ileocolonoscopy and abdominal enterography (isolated perianal fistulas [IPF]) are lacking. We assessed the ability of video capsule endoscopy [VCE] to detect luminal inflammation in patients with IPF. METHODS We studied consecutive adults [>17 years] with IPF who were evaluated by VCE after a negative ileocolonoscopy and abdominal enterography between 2013 and 2022. We defined luminal CD by VCE as diffuse erythema, three or more aphthous ulcers, or a Lewis score greater than 135. We compared rates of intestinal inflammation in this cohort with age- and sex-matched controls without perianal fistulas, who underwent VCE for other indications. We excluded persons with pre-existing inflammatory bowel disease [IBD] and exposure to non-steroidal anti-inflammatory drugs or immunosuppressive treatments. RESULTS A total of 45 patients with IPF underwent VCE without complications. Twelve patients [26%] met our definition of luminal CD. Luminal CD was more common in patients with IPF than in controls [26% vs 3%; p <0.01]. Among patients with IPF, male sex (OR [odds ratio], 9.2; 95% confidence interval [CI] [1.1-79.4]), smoking (OR, 4.5; 95% CI [0.9-21.2]), abscess (OR, 6.3; 95% CI [1.5-26.8]), rectal enhancement on magnetic resonance imaging [MRI] (OR, 9.0; 95% CI [0.8-99.3]), and positive antimicrobial serology (OR, 7.1; 95% CI, [0.7-70.0]) were more common in those with a positive VCE study. CONCLUSIONS VCE detected small intestinal inflammation suggestive of luminal CD in approximately one-quarter of patients with IPF. Larger studies are required to validate these findings.

Risk factors of epidural hematoma in patients undergoing spinal surgery: a meta-analysis of 29 cohort studies. Int J Surg 2023; 109:3147-3158. [PMID: 37318854 PMCID: PMC10583939 DOI: 10.1097/js9.0000000000000538] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 05/25/2023] [Indexed: 06/17/2023]
Abstract
OBJECTIVE The authors conducted this meta-analysis to identify risk factors for spinal epidural haematoma (SEH) among patients following spinal surgery. METHODS The authors systematically searched Pub: Med, Embase, and the Cochrane Library for articles that reported risk factors associated with the development of SEH in patients undergoing spinal surgery from inception to 2 July 2022. The pooled odds ratio (OR) was estimated using a random-effects model for each investigated factor. The evidence of observational studies was classified as high quality (Class I), moderate quality (Class II or III) and low quality (Class IV) based on sample size, Egger's P value and between-study heterogeneity. In addition, subgroup analyses stratified by study baseline characteristics and leave-one-out sensitivity analyses were performed to explore the potential sources of heterogeneity and the stability of the results. RESULTS Of 21 791 articles screened, 29 unique cohort studies comprising 150 252 patients were included in the data synthesis. Studies with high-quality evidence showed that older patients (≥60 years) (OR, 1.35; 95% CI, 1.03-1.77) were at higher risk for SEH. Studies with moderate-quality evidence suggested that patients with a BMI greater than or equal to 25 kg/m² (OR, 1.39; 95% CI, 1.10-1.76), hypertension (OR, 1.67; 95% CI, 1.28-2.17), and diabetes (OR, 1.25; 95% CI, 1.01-1.55) and those undergoing revision surgery (OR, 1.92; 95% CI, 1.15-3.25) and multilevel procedures (OR, 5.20; 95% CI, 2.89-9.37) were at higher risk for SEH. Meta-analysis revealed no association between tobacco use, operative time, anticoagulant use or American Society of Anesthesiologists (ASA) classification and SEH. CONCLUSIONS Obvious risk factors for SEH include four patient-related risk factors, including older age, obesity, hypertension and diabetes, and two surgery-related risk factors, including revision surgery and multilevel procedures. These findings, however, must be interpreted with caution because most of these risk factors had small effect sizes. Nonetheless, they may help clinicians identify high-risk patients to improve prognosis.

Outcomes of gracilis muscle interposition for rectourethral fistulas caused by treatment of prostate cancer. Tech Coloproctol 2023; 27:937-944. [PMID: 36800073 DOI: 10.1007/s10151-023-02759-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 01/24/2023] [Indexed: 02/18/2023]
Abstract
BACKGROUND Gracilis muscle interposition (GMI) has been associated with favorable outcomes in treating complex perianal fistulas. Outcomes of GMI may vary according to the fistula etiology, particularly between rectovaginal fistulas in women and rectourethral fistulas (RUF) in men. The aim of this study was to assess the outcome of GMI to treat RUF acquired after prostate cancer treatment. METHODS This retrospective cohort study included male patients treated with GMI for RUF acquired after prostate cancer treatment between January 2000 and December 2018 in the Department of Colorectal Surgery, Cleveland Clinic Florida. The primary outcome was the success of GMI, defined as complete healing of RUF without recurrence. Secondary outcomes were length of hospital stay and postoperative complications. RESULTS This study included 53 male patients with a median age of 68 (range, 46-85) years. Patients developed RUF after treatment of prostate cancer with radiation (52.8%), surgery (34%), or transurethral resection of the prostate (TURP) (13.2%). Median hospital stay was 5 (IQR, 4-7) days. Twenty (37.7%) patients experienced 25 complications, the most common being wound infection and dehiscence. Primary healing after GMI was achieved in 28 (52.8%) patients. Fifteen additional patients experienced successful healing of RUF after additional procedures, for a total success rate of 81.1%. Median time to complete healing was 8 (range, 4-56) weeks. The only significant factor associated with outcome of GMI was wound dehiscence (p = 0.008). CONCLUSIONS Although the initial success rate of GMI was approximately 53%, it increased to 81% after additional procedures. Complications after GMI were mostly minor, with wound complications being the most common. Perianal wound dehiscence was significantly associated with failure of healing of RUF after GMI.

Abstract
BACKGROUND we designed a prospective study of diagnostic accuracy that compared pelvic MRI and 3D-EAUS with pelvic MRI alone in the preoperative evaluation and postoperative outcomes of patients with perianal fistulas. METHODS the sample size was 72 patients and this was divided into two imaging groups. MRI alone was performed on the first group. Both MRI and 3D-EAUS were performed in parallel on the second group. Surgical exploration took place after two weeks and was the standard reference. Park's classification, the presence of a concomitant abscess or a secondary tract, and the location of the internal opening were recorded. All patients were re-evaluated for complete fistula healing and fecal incontinence six months postoperatively. All of the collected data were subjected to statistical analysis. RESULTS the MRI group included 36 patients with 42 fistulas. The MRI + 3D-EAUS group included 36 patients with 46 fistulas. The adjusted sensitivity and negative predictive value were 1.00 for most fistula types in the group that underwent combined imaging. The adjusted specificity improved for intersphincteric fistulas in the same group. The adjusted balanced accuracy improved for all fistula types except rectovaginal. The combination of imaging methods showed improved diagnostic accuracy only in the detection of a secondary tract. The healing rate at six months was 100%. Fecal incontinence at six months did not present a statistically significant difference between the two groups (Fisher's exact test p-value > 0.9). Patients with complex perianal fistulas had a statistically significant higher probability of undergoing a second surgery (x2 test p-value = 0.019). CONCLUSIONS the combination of pelvic MRI and 3D-EAUS showed improved metrics of diagnostic accuracy and should be used in the preoperative evaluation of all patients with perianal fistulas, especially those with complex types.

Abstract
PURPOSE Evaluation of the effectiveness and tolerability of the application of an OTSC (Ovesco Endoscopy AG Tuebingen, Germany) Proctology clip as an innovative strategy of anorectal fistulae closure when established treatment strategies had already failed or were not feasible. METHODS Retrospective single-center study including consecutive patients treated between March 2014 and March 2016 with the OTSC Proctology system for anorectal fistula closure, including one rectovaginal and one rectourethral fistula. The primary outcome was the healing rate with a minimum follow up of 6 months. Healing was defined as closure of the internal fistula ostium and absence of secretion or local inflammation during follow up. RESULTS A total of 66 fistula closures by the OTSC Proctology clip were investigated, including cryptoglandular fistulas (45/66 patients, 68%), fistulas associated with CED (19/66 patients, 29%), and other non-cryptoglandular fistulas (2/66 patients, 4%). 47% (31/66 patients) had a failed previous therapy. In that selected collective, a successful fistula closure was achieved in 29/66 cases (44%) after a median follow up time of 40 months (6-61 months). Suprasphincteric and high transsphincteric fistulas showed healing in 63% and 42% in CD associated fistulas. CONCLUSION Fistula closure by the OTSC Proctology clip is an innovative, sphincter protecting treatment strategy in anorectal fistulas that can achieve long-term cure in complex anorecta.

Abstract
AIM This article reports the frequency of repeat operations including waiting times within the National Health Service (NHS) of England and Wales. METHODS Retrospective study on repeat operations for anal fistula (AF) performed between 1st January 2010 and 31st December 2016. Data were extracted from the national registry of data entered into Hospital Episode Statistics (HES). Patient factors (age, sex, self-declared ethnicity) and geographical location were tested for association with repeat operations and time to the second operation. RESULTS We analysed 36,223 patients that had an operation for AF within 148 NHS trusts. The median follow-up time was 28 months. The majority of patients (67.4%) had only one operation. Eighty-five per cent of them remained under the care of a single consultant. Six per cent of the repeat surgeries occurred in at least three different treatment sites. Young age and female sex were associated with higher rates of repeat operations. Non-declared and Black or Black British ethnicity were associated with fewer operations. The median waiting time between the first and second operations was 27.4 weeks (IQR: 14.7-55.3); between the second and third 28.0 weeks (IQR: 14.7-57.0); between the third and fourth 29.0 weeks. CONCLUSION This large real world population-based study shows that the majority of patients with AF undergo only one operation. Patients requiring multiple procedures tend to stay under the care of a small number of consultants but waiting times between operations are long. There is a geographical variation in the number of operations and the time between them.

Abstract
Anal fistula is a common proctological disease, but the thorough mechanisms of the anal fistula formation are still unclear. An increasing number of studies have revealed the crucial role of gut microbiota in intestinal diseases. We used 16S rRNA gene sequencing to analyze the intestinal microbiome in order to determine whether there are differences in the microbiome between anal fistula patients and healthy individuals. The microbiome samples were extracted by repeatedly wiping the rectal wall with intestinal swab. Before this operation, the whole intestine of all participants was irrigated and the score of the Boston bowel preparation scale reached 9. The biodiversity of gut microbiome of rectum revealed significant difference between anal fistula patients and healthy individuals. 36 discriminative taxa were identified by LEfSe analysis between two groups. At the phylum level, Synergistetes was enriched in anal fistula patients, while Proteobacteria was higher in healthy individuals. We also found that at the genus level, Blautia, Faecalibacterium, Ruminococcus, Coprococcus, Bacteroides, Clostridium, Megamonas and Anaerotruncus were highly enriched in anal fistula patients, while the microbiome of healthy individuals was enriched with Peptoniphilus and Corynebacterium. Spearman correlations showed the extensive and close association among genera and species. Finally, a diagnostic prediction model was constructed by random forest classifier, and the area under curve (AUC) reached 0.990. This study gave an important hint for analyzing gut microbiome of rectum in anal fistula patient.Keypoints.We use the 16S rRNA gene sequencing to test the microbiome samples extracted from the intestinal swab. This is the first study to explore the gut microbiome of rectum using this workflow. We also found the distinct gut microbiome of rectum differences between anal fistula patients and healthy individuals.

Abstract
Background and Aims Anal fistula (AF) with cryptoglandular origin tends to recur, and multiple risk factors are implicated. Recently, some magnetic resonance imaging (MRI) findings with predictive value for disease outcomes have been proposed. These intrinsic anatomic features include those of the AF and its surrounding structures. This study aims to clarify the prognostic role of MRI in AF. Methods We performed a systematic search of PubMed, Embase, and EBSCO databases. Two independent reviewers conducted the search and screened the articles. We selected studies that used MRI to assess AF and reported its relationship to disease outcome. We extracted data regarding the study design, type of intervention, outcome, MRI-measured items, and their significance. Results Out of 1230 retrieved articles, 18 were eligible for final inclusion, and a total of 4026 patients were enrolled in the selected studies. For preoperative MRI, the significant items affecting the outcome were the length of the fistula, horseshoe type, presence of multiple tracts, supralevator extension, and apparent diffusion coefficient (ADC) value. Other studies investigated the healing process using postoperative MRI. Conclusion This review found that MRI can be useful in the management of AF, both preoperatively and postoperatively. Factors, such as fistula length, horseshoe type, presence of multiple tracts, supralevator extension, and ADC value were found to be significantly associated with treatment outcomes. The presence of the fistula tract and the development of new abscesses on postoperative MRI was found to hinder the healing process. Further studies are needed to confirm these findings.

Abstract
Cryptoglandular anal fistulas are one of the most common colorectal diseases and occur with an incidence of about 20/100,000. Anal fistulas are defined as an inflammatory junction between the anal canal and the perianal skin. They develop from an abscess or chronic infection of the anorectum. Surgical treatment of the disease is the method of choice. Even when treating an acute abscess, its cause should be sought at the same time. If there is a connection to the anal canal without affecting relevant parts of the sphincter muscles, primary fistulotomy should be performed. If larger parts of the sphincter muscle are involved, the insertion of a seton drain is usually useful. There are essentially two recommendations for the elective treatment of cryptoglandular anal fistulas. Distal fistulas should be excised, with the proviso that as little sphincter muscle as possible is sacrificed. In the case of highly proximally located and complex fistulas, sphincter-preserving surgical techniques should be used. In this case, the method of choice is the mucosal or advancement flap. Alternatively, clips, fibrin injections, fistula plugs, fistula ligatures, or laser-based procedures are described in the literature. In the case of intermediate fistulas, a fistulectomy with primary sphincter reconstruction can be useful. Every operation is carried out as a compromise between definitive healing of the fistula and a potential risk to the patient's continence. It is often difficult to make a reliable prognosis about the continence function to be expected postoperatively. In addition to the fistula morphology, particular attention should be paid to whether previous proctological operations have already been performed, the gender of the patient, and whether there are pre-existing sphincter dysfunctions. Since the surgeon's expertise plays a decisive role in the success of the treatment, the procedure should be carried out in a specialist proctological centre, especially in the case of complex fistulas or in the case of a condition after previous operations. In addition to the classic procedures, such as fistulectomy or the plastic fistula closure, this article examines alternative methods and their areas of application.

Abstract
Fistulizing perianal disease is a debilitating complication present in nearly half of all patients diagnosed with Crohn's disease. The majority of anal fistulas arising in these patients are complex. Treatment can be challenging with therapy often requiring both medical and surgical interventions with differing levels of symptomatic relief. Fecal diversion is an option after medical and surgical modalities have been exhausted but demonstrates limited efficacy. Complex perianal fistulizing Crohn's disease is inherently morbid and can be difficult to manage. We present a case of a young male with Crohn's, severe malnutrition and multiple perianal abscess with extensive fistula tracts up to his back; a planned fecal diversion was instituted to control sepsis and allow for wound healing and optimize medical therapy.

Abstract
OBJECTIVE To develop a cryptoglandular Anal Fistula Core Outcome Set: a minimum set of outcomes that should be measured in all studies of cryptoglandular anal fistula treatment. BACKGROUND Variability in the outcomes that are reported in studies of cryptoglandular anal fistula treatment hampers systematic evidence synthesis to identify the best treatment. METHODS This study followed guidance from the Core Outcome Measures in Effectiveness Trials initiative and consisted of three stages: (1) generation of candidate outcomes through systematic review of the literature and qualitative patient interviews; (2) prioritization of outcomes by key stakeholders, including patients, surgeons, gastroenterologists, and radiologists in an online Delphi consensus process; and (3) determination of the final Core Outcome Set (COS) in a consensus meeting attended by patients and clinicians. RESULTS Sixty-four outcomes were presented in the first Delphi survey round. A total of 191 participants from over 30 countries ranked these outcomes according to their importance in defining treatment success (57.6% surgeons and gastroenterologists, 8.9% radiologists, and 33.5% patients). After two rounds, 53 outcomes were identified as important and discussed in the consensus meeting attended by 10 patients and 12 clinicians. A final 10 outcomes were voted into the COS: clinical fistula healing, radiological healing, recurrence, development of additional fistulas, fistula symptoms, incontinence, psychological impact of treatment, complications and reinterventions, patient satisfaction, and quality of life. CONCLUSION The final COS represents an international, multidisciplinary, patient-centered attempt to establish consistency in fistula research, with a substantial focus on patient priorities for treatment.

Abstract
The aim of this study was to introduce a new technique, the bared external anal sphincter technique, and to evaluate its effectiveness and safety for primary or recurrent high horseshoe anal fistula (HHAF). We used data from a tertiary referral hospital's prospective database of a hospital-based cohort. All the patients underwent the bared external anal sphincter procedure. The main outcomes were short-term clinical outcomes including the 6-month cure rate, Visual Analog Scale pain score (VAS-PS) and Cleveland Clinic Florida incontinence score (CCF-IS). The secondary outcomes included the Quality of Life in Patients with Anal Fistula Questionnaire score (QoLAF-QS), Bristol stool chart and postoperative complications. A total of 48 HHAF patients (39 males) with a mean age of 34.2 years (SD 9.04; range, 21-54) were analyzed in this retrospective study. At the 6-month follow-up, the average VAS-PS and CCF-IS were 0.81 (SD 2.28; range, 0-10) and 1.29 (SD 2.87; range, 0-13), respectively. QoLAF-QS showed that the bared external anal sphincter procedure had no impact over their quality of life in 45 patients (93.75%), limited impact in 2 patients (4.16%), and moderate impact in one patient (2.08%). The Bristol stool scale showed that all patients had normal stool characteristics. The 6-month cure rate was 93.75%. Three patients (6.25%) experienced recurrent symptoms but recovered after surgical management. Urinary retention occurred in 1 case (2.78%). No other postoperative complications were reported. No patient had anal incontinence. The bared external anal sphincter procedure is a safe, effective and sphincter-sparing approach for patients with primary or recurrent HHAF in terms of short-term results.

METHODS Patients ≥ 18 years with pCD were included and underwent fistula curettage, SVF with PRP injection, and closure of the internal opening. The primary endpoint was safety at 12 months. The secondary outcomes were complete radiological healing at 3 months (absence of fluid-containing tracts on MRI) and partial and complete clinical response at 3 and 12 months (closure of ≥1, respectively, all treated external opening(s)). RESULTS Twenty-five patients were included (35 [IQR 25-40] years; 14 [56%] female); median CD duration 4 [IQR 2-8] years. Twenty-four (95%) patients had previously undergone fistula surgery. No adverse events were encountered at lipoharvesting sites. Two (8%) patients were readmitted to hospital and six (24%) underwent unplanned re-interventions. Post-operative MRI (n = 24) showed complete radiological healing in nine (37.5%) patients. Partial clinical response was present in 48% (12/25) at 3 months and in 68% (17/25) at 12 months, and complete clinical closure in five (20%) patients at 3 months and in 10 (40%) patients at 12 months. CONCLUSION Injection with autologous SVF with PRP is feasible and safe in patients with treatment-refractory pCD. Early complete radiological healing was observed in more than one-third of patients, and clinical response in two-thirds of patients at 12 months.

Abstract
Abstract
Background
Surgeons find treating perianal fistula difficult because insufficient drainage and failure to eradicate perianal sepsis could increase the risk of recurrence and postoperative complications. For better planning of the most suitable surgical technique, surgeons must consider the risk factors of recurrence with an accurate pre-operative assessment of perianal fistulae.
The most common imaging method for grading primary perianal fistulas, identifying their complications, and locating occult extensions is magnetic resonance imaging (MRI). However, surgeons may find it challenging to read the lengthy reports of complex tracts, particularly for complicated patients. The creation of three-dimensional (3D) models has gained traction recently as a genuinely useful diagnostic tool for pre-operative planning. The authors evaluated the value of these surgical models. Inspecting the 3D models in addition to the routine two-dimensional study caused four out of five skilled colorectal surgeons to re-evaluate how far the fistulae extended. This made promise that 3D models would be helpful, simple to understand, and quick to interpret for colorectal surgeons. The purpose of the study is to assess the value of adding 3D modelling of MRI to standard two-dimensional MRI protocol for more accurate delineation of perianal fistula and its complications aiming at better surgical outcomes.
Results
Regarding 3D models, the highest degree of accuracy was in detecting supra-levator extension (100%) by both the third radiologist and the surgeon. There was a statistically high diagnostic inter-observer agreement between both, with a p-value < 0.0001. The highest inter-observer agreement was in the supra-levator extension (50/50, 100%), and the lowest agreement was in the side branches detection (44/50, 88%).
Conclusions
Pre-operative 3D MRI modelling provided the surgeon with a pre- and intra-operative road map that improved the surgeon’s orientation and ability to see complex perianal fistulas and their consequences, especially those with supra levator extension, thus helping the surgeon achieve better surgical results and decrease the preoperative risk factors of recurrence. Surgeons should utilise it in complex and recurrent cases reducing preoperative risk factors and improving outcomes. Although this technique is expensive, its cost–benefit ratio is low relative to recurrent hospitalisation and complications.

Abstract
Anal fistulas are common anorectal conditions, and surgery is the primary treatment option. In the last 20 years of literature, there exist a large number of surgical procedures, especially for the treatment of complex anal fistulas, as they present more recurrences and continence problems than simple anal fistulas. To date, there are no guidelines for choosing the best technique. We conducted a recent literature review, mainly the last 20 years, based on the PubMed and Google Scholar medical databases, with the goal of identifying the surgical procedures with the highest success rates, lowest recurrence rates, and best safety profiles. Clinical trials, retrospective studies, review articles, comparative studies, recent systematic reviews, and meta-analyses for various surgical techniques, as well as the latest guidelines of the American Society of Colon and Rectal Surgeons, the Association of Coloproctology of Great Britain and Ireland, and the German S3 guidelines on simple and complex fistulas were reviewed. According to the literature, there is no recommendation for the optimal surgical technique. The etiology, complexity, and many other factors affect the outcome. In simple intersphincteric anal fistulas, fistulotomy is the procedure of choice. In simple low transsphincteric fistulas, the patient's selection is crucial in order to perform a safe fistulotomy or another sphincter-saving technique. The healing rate in simple anal fistulas is higher than 95% with low recurrence and without significant postoperative complications. In complex anal fistulas, only sphincter-saving techniques should be used; the optimal outcomes are obtained by the ligation of the intersphincteric fistulous tract (LIFT) and rectal advancement flaps. Those techniques assure high healing rates of 60-90%. The novel technique of the transanal opening of the intersphincteric space (TROPIS) is under evaluation. The novel sphincter-saving techniques of fistula laser closure (FiLac) and video-assisted anal fistula treatment (VAAFT) are safe, with reported healing rates ranging from 65% to 90%. Surgeons should be familiar with all sphincter-saving techniques in order to face the variability of the fistulas-in-ano. Currently, there is no universally superior technique that can treat all fistulas.

Abstract
BACKGROUND Currently, there is no agreement on the best treatment for complex anal fistulas with the least recurrence and lowest complication rate. The aim of this study was to evaluate the long-term recurrence and incontinence after fistulectomy and primary sphincteroplasty (FIPS) in a group of patients with complex perianal fistula. METHODS This prospective observational study was done at the colorectal ward of Taleghani Hospital of Tehran from January 2010 to December 2020. Patients with anal fistula who underwent FIPS were studied. After surgery, patients were evaluated regularly by a colorectal surgeon for fistula recurrence and incontinence. Recurrence was described as a new fistula tract formation after the initial cure and failure of healing in the operation site or any purulent discharge from the fistula tract and openings. In addition, the patient's continence was assessed based on the Wexner score. RESULTS There were 335 patients (66 men and 269 women, mean age 42.74 ± 12.44 years), 191 of them with low fistula and 144 with high fistula. Thirteen patients (3.90%) experienced recurrence (all had a low fistula). Thirty-nine patients (11.64%), 19 patients with high and 20 patients with low fistula, had a Wexner score ≥ 3 during the follow-up. Fifteen patients were lost to follow-up. Male patients (OR = 2.67, 95% CI 0.84, 8.45, p = 0.094, adjusted OR = 4.41, 95% CI 1.05, 18.48, p = 0.042), patients with low fistula (p = 0.001), and recurrent cases had a significantly higher rate of recurrence (OR = 10.38, 95% CI 3.24-33.20 p ≤ 0.001, adjusted OR = 23.36, 95% CI 4.35-125.39, p ≤ 0.001). A significant correlation between body mass index > 35 kg/m2 and incontinence was found (OR = 4.40, 95% CI 1.35, 14.33, p = 0.014). CONCLUSIONS In the present study, an acceptable healing rate and a low percentage of complications following FIPS were seen in patients with complex anal fistula. Randomized clinical trials with appropriate follow-up duration and sample size comparing different surgical methods in these patients are needed to confirm these results.

Abstract
Perianal fistulas are defined as pathological connections between the anorectal canal and the perianal skin. Most perianal fistulas are cryptoglandular fistulas, which are thought to originate from infected anal glands. The remainder of the fistulas mainly arises as complications of Crohn's disease (CD), trauma, or as a result of malignancies. Fistulas in CD are considered as a consequence of a chronic and transmural inflammatory process in the distal bowel and can, in some cases, even precede the diagnosis of CD. Although both cryptoglandular and CD-associated fistulas might look similar macroscopically, they differ considerably in their complexity, treatment options, and healing rate. Therefore, it is of crucial importance to differentiate between these two types of fistulas. In this review, the differences between CD-associated and cryptoglandular perianal fistulas in epidemiology, pathogenesis, and clinical management are discussed. Finally, a flow chart is provided for physicians to guide them when dealing with patients displaying their first episode of perianal fistulas.

Abstract
INTRODUCTION Anal fistula is the natural evolution of perianal abscess and one of the most common perianal diseases for adults. For complex fistula, it is still very challenging for anorectal surgeons to manage. With the introduction of laser technique in surgery, it is becoming more and more widely used for the treatment of cryptoglandular anal fistula. During the past decade, numerous studies have reported the clinical effectiveness and postoperative outcomes of different forms of laser treatment for anal fistula. However, as these studies were varied in terms of baseline characteristics, the evidence for the true clinical effectiveness of laser treatment for anal fistula need further critical appraisal. Therefore, the purpose of this study is to evaluate the outcomes of surgical laser therapy for cryptoglandular anal fistula stratified by laser type and Parks' classification through a synthesis of quantitative and qualitative evidence. METHODS AND ANALYSIS This study will be carried out with adherence to the Cochrane Handbook. We will search PubMed, Cochrane Library, and Embase until June, 2022 to identify all relevant interventional and observational studies examining the effects of laser therapy on the clinical outcomes for cryptoglandular anal fistula. Data extraction from eligible studies will be performed independently by two unblinded authors using standardized extraction forms. Risk of bias assessment for each study will be conducted using Cochrane tool for randomized controlled trials (RCTs) and the Newcastle-Ottawa scale (NOS) tool for observational studies. The DerSimonian-Laird random-effects model will be used to calculate the pooled estimates. Heterogeneity will be examined by subgroup analysis stratified by laser type and Parks' classification and other study characteristics. Potential publication bias will be assessed by funnel plot symmetrical and Egger's regression tests. CONCLUSIONS The synthesis of quantitative and qualitative evidence of this systemic review will yield updated and comprehensive evidence of laser treatment on specific outcomes, which can provide anorectal surgeons with high level evidence-based recommendations to improve patient care and clinical outcomes.

Abstract
Purpose The role of surgery in managing perianal abscesses in the pediatric population is debatable, and data on recurrence risk is rare. This study aimed to evaluate the efficiency of surgery for a perianal abscess in children and identify parameters that predict recurrence. Methods We performed a retrospective review of all children younger than age 14 requiring surgery for a perianal abscess from 2000 to 2018. Results Out of 103 enrolled patients, 27 (26%) had recurrent perianal disease. Recurrences appeared after a median of 5 months (range: 1-18 months), in 12 cases as perianal abscess and 15 cases as fistula in ano. Anal fistula probing was performed in 33% of all patients, of which 16 (15%) underwent fistulotomy. In univariate analysis, older age (p = 0.034), fistula probing (p = 0.006) and fistulotomy (p = 0.009) was associated with treatment success. History of perianal abscess, multilocal occurrence, and the presence of enteric flora in wound swabs was associated with treatment failure (p = 0.002, OR = 0.032). In multivariate analysis, anal fistula probing was independently associated with treatment success (p = 0.019, OR = 22.08), while the history of perianal abscess was associated with treatment failure (p = 0.002, OR = 0.032). Conclusion Our study identified probing for fistula as a predictor of therapy success, while the history of perianal abscess was identified as a predictor of treatment failure. Therefore, in all children with perianal abscess, fistula probing and if present, fistulotomy should be performed.

Abstract
Introduction: Anal fistula is one of the commonest ailments seen by anorectal surgeons as surgery is currently the preferred treatment for it. Diabetes mellitus is a risk factor that can lead to slow wound healing after anal fistula surgery. Because of the large postoperative wound surface of anal fistula, patients with diabetes can have an increased probability of wound infection, which makes it hard to heal. There is an extensive clinical experience for wound healing in traditional Chinese medicine (TCM). The Jiedu Shengji decoction (JSD) is a widely used external washing decoction in clinical practice. However, the current evidence on it is still insufficient. Therefore, we report this carefully designed clinical trial to assess the efficacy and safety of JSD in the treatment of postoperative wounds in diabetic patients with anal fistula. Methods and analysis: This study was designed to be a randomized, double-blind, placebo-controlled, multi-center clinical trial. There were 60 eligible participants who were randomized at a 1:1 ratio to the intervention and placebo groups. Both groups received the same standard treatment. The intervention group was given external washing decoction of TCM (JSD), while the placebo group was given the placebo made of excipients and flavoring agents. The main outcome measures include wound healing, distribution of wound pathogens, levels of inflammatory mediators, and blood glucose. The secondary outcome measures included lipids, the quality of the life evaluation scale (Short-Form Health Survey 36). Assessments were performed before the start of the study, at 1st, 2nd, 3rd, and 4th weeks after the intervention, and at 8th, 12th, and 16th follow-up weeks. Discussion: The clinical study we proposed will be the first randomized, double-blind, placebo-controlled, multi-center clinical trial study to assess the efficacy and safety of TCM external washing (JSD) in the treatment of postoperative wounds in diabetic patients with anal fistula. Ethics and dissemination: The Medical Ethics Committee of Hospital of Chengdu University of Traditional Chinese Medicine has reviewed this study protocol and gave its approval and consent on 17 March, 2022 (Ethical Review Number: 2022KL-018).

Abstract
Abstract
Purpose
To retrospectively assess the accuracy of magnetic resonance imaging (MRI) in defining dentate line in anal fistula.
Materials and methods
Seventy patients with anal fistulas were assessed by dynamic contrast-enhanced MRI. The distance from the dentate line to the anal verge for all patients was measured by MRI. To mitigate interference, 35 patients with anal fistulas whose internal openings were located on the dentate line were excluded from this study. Two observers independently judged the positional relationship between the internal opening and the MRI-defined dentate line, and compared with the results observed by surgeon to assess the accuracy.
Results
The distance between the MRI-defined dentate line and the anal verge depended on the location of the internal opening and the morphology of the anal canal mucosa. The distance based on the location the internal opening and the morphology of the anal canal mucosa was 18.2 ± 8.1 mm and 20.0 ± 5.3 mm on oblique coronal T2WI, respectively. Compared with the results observed by the surgeon, the accuracy of evaluating the positional relationship between the internal opening and the dentate line from the morphology of the anal canal mucosa on MRI exceeded 89.9%. Taking 18.2–20.0 mm as the distance between the dentate line and the anal verge on the MRI image, the accuracy of evaluating the relationship between the position of the internal opening and the dentate line was over 85.7%. Considering both the dentate line and the anal canal mucosa, the accuracy of evaluating the relationship between the internal opening and the dentate line was over 91.5%. The results of MRI-defined dentate line were in good agreement with the results of intraoperative surgeon evaluation, and the κ values were 0.70, 0.63, and 0.78, respectively.
Conclusion
MRI has high accuracy in defining the dentate line in anal fistulas.

Autologous Bioactive Compound Concentrated Growth Factor Ameliorates Fistula Healing of Anal Fistula in a Pig Model and Promotes Proliferation and Migration of Human Skin Fibroblasts via Regulating the MEK/ERK Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:7660118.

Abstract
Recent evidence suggested that autologous concentrated growth factor (CGF), a new bioactive compound from autologous blood is used widely as an ingenious biomaterial in tissue regeneration with anti-inflammatory properties. This study investigated whether CGF could be involved in the treatment of fistula healing in the anal fistula. For this purpose, the porcine anal fistula model was conducted using the rubber band ligation method and collected pig autogenic CGF to treat the fistulas. CGF treatment promoted fistula healing, which was reflected in the downregulation of inflammatory factors, upregulation of growth factors, and promoted epithelial-mesenchymal transition with increased collagen synthesis. Besides, 16S rRNA gene sequencing analysis of fistula tissues between the control and CGF groups showed that the microbial populations exhibiting significant differences were VadinCA02, Blastomonas, Deinococcus, Devosia, Sphingomonas, Rubrobacteria, and GW_34. CGF of volunteers were collected to process small interfering RNA- (siRNA-) ERK or siRNA-negative control transfected human skin fibroblasts (HSF). The results showed that CGF also promoted the proliferation and extracellular matrix-related functions in HSF, as well as activated the MEK/ERK pathway in vitro and in vivo. Finally, knockdown ERK reversed the effects of CGF in promoting wound healing in HSF. Collectively, our results suggest that the CGF as the bioactive compound from autologous blood exhibited great potential for repairing fistulas as well as promoting the proliferation and migration of human skin fibroblasts by triggering MEK/ERK signaling. These findings provided a fresh perspective for understanding the role of CGF in the management of fistulas.

Abstract
Background Definitive management of acute fistula-abscess (anal fistulas associated with acute abscess) is gaining popularity against the two-staged approach (early abscess drainage with deferred fistula management). However, locating an internal opening (IO) in acute fistula-abscess can be difficult. A recent protocol (Garg protocol) has been shown to be effective in managing anal fistulas with non-locatable IO. Purpose To test the efficacy of the Garg protocol in managing acute fistula-abscess with non-locatable IO. Methods Patients with acute fistula-abscess operated by a definitive procedure were included. A preoperative MRI was done in all patients. Patients in whom the IO was non-locatable after clinical, MRI, and intraoperative examination were managed by the three-step Garg protocol. Garg protocol: 1) Reassessment of MRI; 2) In non-horseshoe fistulas, the IO was assumed to be at the point where the fistula tract reached closest to the sphincter-complex; 3) In horseshoe fistulas, the IO was assumed to be located in the midline (anterior or posterior as per the horseshoe location). Low fistulas were treated by fistulotomy and high fistulas by a sphincter-sparing procedure. The long-term healing rate and change in continence (Vaizey scores) were evaluated. Results A total of 201 patients with acute fistula-abscess were operated over six years, and 19 were lost to follow-up. A total of 182 patients (154-males) were followed up (median-37 months). The IO was locatable in 133/182 (73.1%) (control group) and was non-locatable in 49/182 (26.9%) (study group). The study group was managed as per the Garg protocol. The age, sex-ratio, and fistula parameters were comparable in both groups. The long-term healing rate was 112/133(84.2%) in the IO-locatable group and 43/49 (87.8%) in the IO-non-locatable group (p=0.64, not-significant). The objective continence scores did not change significantly after surgery in both groups. Conclusion Acute fistula-abscess with non-locatable IO can be managed successfully by the Garg protocol without any risk of incontinence.

Colorectal Dis 2022; 24:1197-1203. [PMID: 35502697 DOI: 10.1111/codi.16168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Revised: 04/14/2022] [Accepted: 04/21/2022] [Indexed: 02/08/2023]
Abstract
AIM The aim of this work is to describe the clinicopathological and surgical aspects of fistula-in-ano and assess the risks associated with recurrence of the disease in a Ghanaian teaching hospital. METHOD This was a retrospective observational study assessing all fistula-in-ano surgeries performed at the Korle Bu Teaching hospital from January 2014 to January 2021 that had completed follow up of at least 3 months after wound healing. Demographic, clinical, pathological and surgical data were extracted from patient records. Logistic regression analysis was used to test for association between these variables and recurrence. RESULTS A total of 105 patients underwent 124 fistula surgeries. Their median age was 41 years, the male:female ratio was 4:1 and 12 had comorbidities including human immunodeficiency virus infection and diabetes mellitus. Thirty-one per cent (39/124) of fistulas had previously been operated on. At surgery, 51% (64/124) of fistulas followed a single straight tract, 30% (37/124) a single curved tract and 19% (23/124) had multiple curved tracts. More than half (65/124) were trans-sphincteric, 35% (44/124) suprasphincteric, 10% (12/124) subsphincteric and 2% (3/124) were intersphincteric. Sixty per cent of fistulas were treated with a ligation of intersphincteric fistula tract (74/124), 35% (44/124) a fistulectomy and 5% a fistulotomy. Recurrence after surgery was 22.5% (28/124); this was significantly higher for fistulas with multiple curved tracts (OR 4.153, 95% CI 1.431-12.054, p = 0.012) and fistulas with comorbidities (OR 3.222, 95% CI 1.076-9.647, p = 0.037). CONCLUSION There was high recurrence after fistula surgery with increased risk for fistulas with multiple tracts and the presence of comorbidities.

CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:1905279. [PMID: 36176927 PMCID: PMC9499773 DOI: 10.1155/2022/1905279] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 07/25/2022] [Accepted: 07/29/2022] [Indexed: 11/17/2022]
Abstract
Objective To explore the efficacy of Chinese herbal fumigation and sitz-bath combined with red ointment in the treatment of postoperative wound healing and pain control in anal fistula patients. Methods A total of 118 anal fistula patients were selected as the study population, randomly divided into two groups, i.e., the research group (n = 60) and the control group (n = 60). The control group was treated with red ointment therapy for postoperative wound healing and pain while the research group was treated with a combination of ointment and traditional Chinese medicine fumigation sitz-bath, Postoperative wound healing, pain control, and safety evaluation were compared between the two groups. Results. The total effective rate in the research group was 96.67%, which was significantly higher than that in the control group (93.10%), and the difference was statistically significant (P < 0.05). The VAS scores and postoperative wound healing times in the research group were significantly lower than those in the control group. The difference was statistically significant (P < 0.05). A day after postoperative treatment, there was no significant difference (P > 0.05) in TNF-α and IL-6 levels between the two study groups; however, from day 3 to day 14 the levels were statistically different. TNF-α and IL-6 levels in research group were significantly lower than those in the control group. The difference was statistically significant (P < 0.05). The incidence of postoperative complications in the research group at 6.67% was statistically significant (P < 0.05), significantly lower than 13.79% in the control group. Conclusion. Postoperative intervention with Chinese herbal fumigation and sitz-bath combined with red ointment can effectively reduce the wound healing duration and lower the degree of pain experienced by anal fistula patients, thereby improving their quality of life.

Prevalence and factors associated with the awareness of obstetric fistula among women of reproductive age in The Gambia: a multilevel fixed effects analysis. BMC Public Health 2022; 22:1736. [PMID: 36100843 PMCID: PMC9472433 DOI: 10.1186/s12889-022-14107-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Accepted: 08/29/2022] [Indexed: 11/25/2022] Open
Abstract
Background An obstetric fistula is an inappropriate connection between the vagina, rectum, or bladder that results in faecal or urine incontinence. Young women from rural areas with poor socioeconomic situations and education are the majority of victims, which restricts their access to high-quality healthcare. Obstetric fistulas can have devastating effects on the physical health of affected women if they are not promptly treated. Inadequate awareness of the symptoms delays recognition of the problem, prompt reporting, and treatment. Women with poor awareness of the disorder are also more likely to develop complications, including mental health issues. Using data from a nationally representative survey, this study investigated the prevalence and factors associated with the awareness of obstetric fistula among women of reproductive age in The Gambia. Methods This study used population-based cross-sectional data from the 2019–2020 Gambia Demographic and Health survey. A total of 11823 reproductive-aged women were sampled for this study. Stata software version 16.0 was used for all statistical analyses. Obstetric fistula awareness was the outcome variable. Multilevel logistic regression models were fitted, and the results were presented as adjusted odds ratios (aOR) with statistical significance set at p < 0.05. Results The prevalence of obstetric fistula awareness was 12.81% (95%CI: 11.69, 14.12). Women aged 45–49 years (aOR = 2.17, 95%CI [1.54, 3.06]), married women (aOR = 1.39, 95%CI [1.04, 1.87]), those with higher education (aOR = 2.80, 95%CI [2.08, 3.79]), and women who worked as professionals or occupied managerial positions (aOR = 2.32, 95%CI [1.74, 3.10]) had higher odds of obstetric fistula awareness. Women who had ever terminated pregnancy (aOR = 1.224, 95%CI [1.06, 1.42]), those who listened to radio at least once a week (aOR = 1.20, 95%CI [1.02, 1.41]), ownership of a mobile phone (aOR = 1.20, 95%CI [1.01, 1.42]) and those who were within the richest wealth index (aOR = 1.39, 95%CI [1.03, 1.86]) had higher odds of obstetric fistula awareness. Conclusion Our findings have revealed inadequate awareness of obstetric fistula among women of reproductive-age in The Gambia. Obstetric fistulas can be mitigated by implementing well-planned public awareness initiatives at the institutional and community levels. We, therefore, recommend reproductive health education on obstetric fistula beyond the hospital setting to raise reproductive-age women's awareness.

Abstract
While generally perceived as mundane and low-risk procedures, anorectal surgeries by virtue of their anatomic real-estate-dense with nerves, blood supply, and structures critical to the quality of life-are fraught with the potential for complications. While these complications are generally not life-threatening, their impact to the quality of life can be severe. Furthermore, the sheer volume of anorectal procedures performed each year means that even low complication rates or less severe complications can have significant economic impact.

Abstract
Recent trends in benign anal disease treatment are minimizing surgery to preserve normal anorectal anatomical unit and its functions. However, some surgeons still prefer and are confident with the use of conventional solid surgical methods. In this report, we will investigate the recent trends in the treatment for hemorrhoids, fistula, and anal fissure. The practice guidelines of advanced countries, including UK, Italy, France, USA, Japan, and ESCP, are referred to in this review. Opinions suggested in international meetings were also added. In the management of hemorrhoids, surgical treatments and office procedures were recommended according to a patient's status and preference. For the management of complex anal fistula, novel sphincter-preserving surgical techniques are more widely accepted than a sphincter-dividing procedure of immediate repair following fistulectomy. The treatment of anal fissures is well covered in the guidelines of the ASCRS.

Abstract
Complex anal fistulas are difficult to treat. The main reasons for this are a higher recurrence rate and the risk of disrupting the continence mechanism because of sphincter involvement. Due to this, several sphincter-sparing procedures have been developed in the last two decades. Though moderately successful in simple fistulas (50%-75% healing rate), the healing rates in complex fistulas for most of these procedures has been dismal. Only two procedures, ligation of intersphincteric fistula tract and transanal opening of intersphincteric space have been shown to have good success rates in complex fistulas (60%-95%). Both of these procedures preserve continence while achieving high success rates. In this opinion review, I shall outline the history, compare the pros and cons, indications and contraindications and future application of both these procedures for the management of complex anal fistulas.

World J Gastrointest Surg 2022; 14:271-275.

Abstract
The main purpose of a radiologist’s expertise in evaluation of anal fistula magnetic resonance imaging (MRI) is to benefit patients by decreasing the incontinence rate and increasing the healing rate. Any loss of vital information during the transfer of this data from the radiologist to the operating surgeon is unwarranted and is best prevented. In this regard, two methods are suggested. First, a short video to be attached with the standardized written report highlighting the vital parameters of the fistula. This would ensure minimum loss of information when it is conveyed from the radiologist to the operating surgeon. Second, inclusion of a new parameter, the amount of external sphincter involvement by the anal fistula. This parameter is usually not included in the MRI report. This can be evaluated as the height of penetration of the external anal sphincter (HOPE) by the fistula. The external anal sphincter plays a pivotal role in maintaining continence. This parameter (HOPE) is distinct from the ‘height of internal opening’ and assumes immense importance as its knowledge is paramount to prevent damage to the external anal sphincter by the surgeon during surgery.

Abstract
Summary
Background
Rectovaginal fistulas represent 5% of all anorectal fistulas. For affected women, this pathology is associated with a reduction in quality of life (QoL) and self-esteem. Most commonly used methods of surgical closure have high recurrence rates or permanent perineal complaints, which in turn lead to negative effects on QoL and self-esteem. A fistula closure, using the “de-epithelialized Singapore flap” (SF), can be a good alternative therapy strategy.
Method
Our retrospective case series processes the long-term results of seven patients who were operated on for ano-/rectovaginal fistula using the SF. All patients underwent surgery at the University Hospital Graz, between May 2012 and July 2015. The data of the surgical follow-up examinations were collected and an additional telephone survey was carried out. The procedure is presented based on a structured description. All procedures were performed jointly by the Department of General Surgery and the Department of Plastic Surgery.
Results
The average age of the seven patients was 46.14 years (23–72 a). Five patients had a total of 12 previous operations with frustrating results. Of the seven patients treated, six had a permanent fistula closure (85.7%). The results of the telephone survey (n = 6) showed a high level of patient satisfaction (100%), and an improvement in QoL (83.3%), through our surgical method. In our cohort, neither urinary nor fecal incontinence occurred.
Conclusion
The treatment of an ano-/rectovaginal fistula using the “de-epithelialized pudendal thigh flap” (Singapore flap) is a promising treatment alternative. In particular, patients who have had previous proctological interventions show a benefit from this procedure.

Abstract
Background Anal fistulas cause great uncertainty and anxiety in patients and surgeons alike. This is largely because of the inability to accurately confirm postoperative fistula healing, especially long-term healing. There is no scoring system available that can objectively assess cryptoglandular anal fistulas for postoperative healing and can also accurately predict long-term healing. Methods Several parameters that could indicate anal fistula healing were assessed. Out of these, six parameters (four MRI-based and two clinical) were finalized, and a weighted score was given to each parameter. A novel scoring system (NSS) was developed. A minimum possible score (zero) indicated complete healing whereas the maximum weighted score (n = 20) indicated confirmed non-healing. Scoring was done with postoperative MRI (at least 3 months post-surgery), then compared with the actual healing status, and subsequently correlated with the final long-term clinical outcome. Results The NSS was validated in 183 operated cryptoglandular fistula-in-ano patients over a 3-year period in whom 283 MRIs (preoperative plus postoperative) were performed. The postoperative follow-up was 12–48 months (median-30 months). The NSS was found to have a very high positive predictive value (98.2%) and moderately high negative predictive value (83.7%) for long-term fistula healing. Additionally, its sensitivity and specificity in predicting healing were 93.9% and 94.7%, respectively. Conclusion Thus, this new scoring system is highly accurate and would be a useful tool for surgeons and radiologists managing anal fistulas. By objectivizing the assessment of postoperative healing, it can both ease and streamline management. Moreover, reliable prediction of recurrence-free long-term healing will greatly allay the apprehensions associated with this dreaded disease.

Abstract
BACKGROUND Children with perianal fistulizing Crohn disease require intensive medical management but also have a higher risk for subsequent surgical interventions. OBJECTIVE We performed a retrospective study to identify patient factors and perianal anatomical features by pelvic MR that are associated with surgical interventions in these children. MATERIALS AND METHODS We included children with Crohn disease and perianal fistula who underwent pelvic MR with available, archived images and collected demographic, clinical and laboratory data. Radiologists reviewed pelvic MR exams and identified Park classification and additional anatomical features of perianal fistulas, including fistula branching, horseshoe ramifications, abscess, inflammatory mass, supralevator extension, anal sphincter damage, proctitis and posterior anal space involvement. We performed univariate and subsequent multivariate analysis to determine features associated with subsequent surgical intervention. RESULTS Ninety-nine children with Crohn disease underwent pelvic MR. In this cohort, 69 children had no surgical interventions prior to baseline MRI, with subsequent median clinical follow-up of 5.5 years. Univariate analysis demonstrated that branching (P=0.009), supralevator extension (P=0.015) and anal sphincter damage (P=0.031) were significantly associated with subsequent surgical intervention. Age at baseline MRI was also associated with intervention (hazard ratio [HR] every 5 years: 2.13; 95% confidence interval [CI]: 1.18-3.83; P=0.012). A multivariable model identified only fistula branching (HR: 2.31; 95% CI: 1.28-4.15; P=0.005) and age (HR: 5.18; CI: 1.57-17.14; P=0.007) as independent predictors of subsequent surgery. No demographic, clinical or laboratory parameter predicted subsequent surgical intervention. CONCLUSION Age and anatomical MR features indicating fistula complexity (branching, supralevator extension) and sphincter damage confer a higher risk of subsequent surgical intervention in children with perianal Crohn disease.
