Abstract
The gastrointestinal tract harbors diverse microorganisms in the lumen. Epithelial cells segregate the luminal microorganisms from immune cells in the lamina propria by constructing chemical and physical barriers through the production of various factors to prevent excessive immune responses against microbes. Therefore, perturbations of epithelial integrity are linked to the development of gastrointestinal disorders. Several mesenchymal stromal cell populations, including fibroblasts, myofibroblasts, pericytes, and myocytes, contribute to the establishment and maintenance of epithelial homeostasis in the gut through regulation of the self-renewal, proliferation, and differentiation of intestinal stem cells. Recent studies have revealed alterations in the composition of intestinal mesenchymal stromal cells in patients with inflammatory bowel disease and colorectal cancer. A better understanding of the interplay between mesenchymal stromal cells and epithelial cells associated with intestinal health and diseases will facilitate identification of novel biomarkers and therapeutic targets for gastrointestinal disorders. This review summarizes the key findings obtained to date on the mechanisms by which functionally distinct mesenchymal stromal cells regulate epithelial integrity in intestinal health and diseases at different developmental stages.

García-Olmo D, Gómez-Barrera M, de la Portilla F. Surgical management of complex perianal fistula revisited in a systematic review: a critical view of available scientific evidence. BMC Surg 2023; 23:29. [PMID: 36740680 PMCID: PMC9901165 DOI: 10.1186/s12893-023-01912-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 01/10/2023] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Treating complex perianal fistulas in Crohn's disease patients remains a challenge. Classical surgical treatments for Crohn's disease fistulas have been extrapolated from cryptoglandular fistulas treatment, which have different etiology, and this might interfere with its effectiveness, in addition, they increase fecal incontinence risk. Recently, new surgical techniques with support from biological approaches, like stem cells, have been developed to preserve the function of the sphincter. We have performed a systematic literature review to compare the results of these different techniques in the treatment of Crohn's or Cryptoglandular fistula. METHODS PubMed, EMBASE, Database of Abstracts of Reviews of Effectiveness, Cochrane Central Register of Controlled Trials were searched systematically for relevant articles. We included randomized controlled trials and observational studies that referred to humans, were written in English, included adults 18+ years old, and were published during the 10-year period from 2/01/2010 to 2/29/2020. Evidence level was assigned as designated by the Scottish Intercollegiate Guidelines Network. RESULTS Of the 577 citations screened, a total of 79 were ultimately included in our review. In Crohn's disease patients, classical techniques such as primarily seton, Ligation of Intersphincteric Fistula Tracks, or lay open, healing rates were approximately 50-60%, while in cryptoglandular fistula were around, 70-80% for setons or flaps. In Crohn's disease patients, new surgical techniques using derivatives of adipose tissue reported healing rates exceeding 70%, stem cells-treated patients achieved higher combined remission versus controls (56.3% vs 38.6%, p = 0.010), mesenchymal cells reported a healing rate of 80% at week 12. In patients with cryptoglandular fistulas, a healing rate of 70% using derivatives of adipose tissue or platelets was achieved, and a healing rate of 80% was achieved using laser technology. Fecal incontinence was improved after the use of autologous platelet growth factors and Nitinol Clips. CONCLUSION New surgical techniques showed better healing rates in Crohn's disease patients than classical techniques, which have better results in cryptoglandular fistula than in Crohn's disease. Healing rates for complex cryptoglandular fistulas were similar between the classic and new techniques, being the new techniques less invasive; the incontinence rate improved with the current techniques.

Colorectal Dis 2021; 23:178-185. [PMID: 33155391 PMCID: PMC7898619 DOI: 10.1111/codi.15429] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 09/25/2020] [Accepted: 10/03/2020] [Indexed: 12/14/2022]
Abstract
AIM To evaluate the long-term success rate of treatment with the Surgisis® (Biodesign® ) anal fistula plug for complex anal fistulas, assess fistula plug failure over time and compare success rates for fistula plug between a group of patients with cryptoglandular fistula and another group with Crohn's fistula. METHOD This is a single-centre study of consecutive patients treated with the Surgisis® (Biodesign® ) anal fistula plug between May 2006 and October 2009. All patients had complex anal fistulas in need of surgical treatment. The patients were assessed preoperatively by physical examination and three-dimensional (3D) endoanal ultrasound, and treated with a loose seton. Postoperative assessment by clinical examination and 3D endoanal ultrasound was performed at 2 weeks, 3 months and 6-12 months. Long-term follow-up was carried out in 2017 using a questionnaire, and clinical examination combined with 3D endoanal ultrasound was performed if the questionnaire indicated any signs of fistula recurrence. RESULTS A total of 95 patients were included; 30 had quiescent Crohn's disease. Overall, 151 plug procedures were performed. Long-term follow-up was undertaken in 90 (95%) patients; the results showed that after a median period of 110 months, the overall healing rate after one to five plug procedures was 38%. No statistically significant difference in success rate was found between the cryptoglandular fistula group and the Crohn's fistula group (P = 0.37). No further healing was observed after the use of three plugs. CONCLUSION Considering its low morbidity in a complex disease with high recurrence rates over time, the anal fistula plug may still be considered as one of the first-line treatments for patients with complex anal fistulas.

Abstract
BACKGROUND An anal fistula plug is a sphincter-sparing procedure that uses biological substances to close an anorectal fistula. This study aimed to evaluate the long-term therapeutic effect of an anal fistula plug procedure in patients with trans-sphincteric fistula-in-ano and to determine the risk factors affecting fistula healing. MATERIAL AND METHODS A single-center retrospective study was performed assessing long-term treatment outcomes of patients with low trans-sphincteric anal fistulas who initially underwent anal fistula plug procedures between August 2008 and September 2012. Risk factors affecting fistula healing were identified using univariate and multivariate analyses. RESULTS A total of 135 patients who had low trans-sphincteric anal fistulas and underwent anal fistula plug procedures were analysed. The overall healing rate was 56% (75/135) with a median follow-up time of 8 years (range, 72-121 months). The primary reasons for treatment failure were plug extrusion (n=12, 20%) and surgical site infection (n=9, 15%), occurring within 30 days after surgery. Multiple logistic regression analysis showed that the duration of anal fistula ≥6 months was significantly associated with treatment failure using an anal fistula plug (OR=3.187, 95% CI: 1.361-7.466, P=0.008). Of the patients who failed initial treatment with an anal fistula plug, 6 (9%) had anal fistulas that healed spontaneously after 2-3 years without additional treatment. CONCLUSIONS As a sphincter-preserving procedure, the anal fistula plug can effectively promote healing of low trans-sphincteric anal fistulas. The long-term efficacy is good and the procedure warrants wider use in clinical practice.

Abstract
One of the most challenging phenotypes of Crohn’s disease is perianal fistulizing disease (PFCD). It occurs in up to 50% of the patients who also have symptoms in other parts of the gastrointestinal tract, and in 5% of the cases it occurs as the first manifestation. It is associated with severe symptoms, such as pain, fecal incontinence, and a significant reduction in quality of life. The presence of perianal disease in conjunction with Crohn’s disease portends a significantly worse disease course. These patients require close monitoring to identify those at risk of worsening disease, suboptimal biological drug levels, and signs of developing neoplasm. The last 2 decades have seen significant advancements in the management of PFCD. More recently, newer biologics, cell-based therapies, and novel surgical techniques have been introduced in the hope of improved outcomes. However, in refractory cases, many patients face the decision of having a stoma made and/or a proctectomy performed. In this review, we describe modern surgical management and the most recent advances in the management of complex PFCD, which will likely impact clinical practice.

Abstract
This article is the second in a series of two publications relating to the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the management of Crohn's disease. The first article covers medical management; the present article addresses surgical management, including preoperative aspects and drug management before surgery. It also provides technical advice for a variety of common clinical situations. Both articles together represent the evidence-based recommendations of the ECCO for Crohn's disease and an update of previous guidelines.

Abstract
Background Perianal fistulizing Crohn's disease is associated with severe symptoms such as pain, fecal incontinence, and a significant reduction in quality of life. Results In refractory cases, many patients face the decision of having a stoma and/or requiring proctectomy. In former years, the standard of care was a complete fistulectomy, bringing with it a high rate of continence disorders. Additionally, many patients received indefinite treatment, namely the placement of a seton to maintain surgical drainage. Conclusion More recently, newer biologics, cell-based therapies as well as novel surgical techniques have been introduced, raising new hopes that outcomes can be improved upon.

Abstract
AIM The aim was to compare the effectiveness of the anal fistula plug (AFP) with the rectal advancement flap (RAF) for complex cryptoglandular anal fistulas. METHODS We conducted a literature search to identify relevant available articles published without language restriction from Embase and PubMed databases and the Cochrane Library. Studies comparing outcomes with the AFP vs RAF for complex cryptoglandular anal fistulas were eligible for inclusion. RESULTS A total of 11 articles with 810 patients were included in this meta-analysis. Four RCTs and one observational clinical study provided long-term follow-up. The pooled analysis of all 11 studies indicated that there was no significant difference between the AFP and RAF in terms of healing rate, recurrence rate and incidence of fistula complications. However, the pooled results of studies with long-term follow-up revealed that the RAF group had a significantly higher healing rate (OR 0.32, 95% CI 0.13, 0.78, P = 0.01) and lower recurrence rate (OR 4.45, 95% CI 1.45, 13.65, P = 0.009) than the AFP group. CONCLUSIONS For the treatment of complex cryptoglandular anal fistulas, the RAF was superior to the AFP in terms of healing and recurrence rate after pooling of randomized controlled trials with long-term follow-up, even though a comparison based on the pooling of all studies showed no significant difference.

Abstract
Background The aim of this study was to evaluate the effectiveness of gracilis muscle transposition (GMT) to treat recurrent anovaginal, rectovaginal, rectourethral, and pouch–vaginal fistulas in patients with inflammatory bowel disease (IBD). Methods A retrospective study was conducted in patients with IBD who had GMT performed by a single surgeon between 2000 and 2018. Follow-up data regarding healing rate, complications, additional procedures, and stoma closure rate was collected. Results A total of 30 women and 2 men had GMT. In all patients fistula was associated with Crohn's disease. In 1 female patient, contralateral gracilis transposition was required after a failed attempt at repair. The primary healing rate was 47% (15/32) and the definitive healing rate (healed by the time of data collection and after secondary procedures) was 71% (23/32). Additional surgical procedures due to fistula persistence or recurrence were performed on 17 patients (53%).At least 7 patients (21%) suffered complications including one wound infection with ischemia of the gracilis muscle. Stoma closure was successful in 18 of 31 cases of patients with stoma (58% of the patients). Conclusions GMT for the treatment of recurrent and complex anorectal fistulas in patients with IBD patient is eventually successful in almost 2/3 of patients.

Abstract
Background Anal fistula occurs in approximately one in three patients with Crohn's disease and is typically managed through a multimodal approach. The optimal surgical therapy is not yet clear. The aim of this systematic review was to identify and assess the literature on surgical treatments of Crohn's anal fistula. Methods A systematic review was conducted that analysed studies relating to surgical treatment of Crohn's anal fistula published on MEDLINE, Embase and Cochrane databases between January 1995 and March 2016. Studies reporting specific outcomes of patients treated for Crohn's anal fistula were included. The primary outcome was fistula healing rate. Bias was assessed using the Cochrane ROBINS‐I and ROB tool as appropriate. Results A total of 1628 citations were reviewed. Sixty‐three studies comprising 1584 patients were ultimately selected in the analyses. There was extensive reporting on the use of setons, advancement flaps and fistula plugs. Randomized trials were available only for stem cells and fistula plugs. There was inconsistency in outcome measures across studies, and a high degree of bias was noted. Conclusion Data describing surgical intervention for Crohn's anal fistula are heterogeneous with a high degree of bias. There is a clear need for standardization of outcomes and description of study cohorts for better understanding of treatment options.

Abstract
The synthesis and secretion of components that constitute the extracellular matrix (ECM) by resident cell types occur at the earliest stages of embryonic development, and continue throughout life in both healthy and diseased physiological states. The ECM consists of a complex mixture of insoluble and soluble functional components that are arranged in a tissue-specific 3D ultrastructure, and it regulates numerous biological processes, including angiogenesis, innervation and stem cell differentiation. Owing to its composition and influence on embryonic development, as well as cellular and organ homeostasis, the ECM is an ideal therapeutic substrate for the repair of damaged or diseased tissues. Biologic scaffold materials that are composed of ECM have been used in various surgical and tissue-engineering applications. The gastrointestinal (GI) tract presents distinct challenges, such as diverse pH conditions and the requirement for motility and nutrient absorption. Despite these challenges, the use of homologous and heterologous ECM bioscaffolds for the focal or segmental reconstruction and regeneration of GI tissue has shown promise in early preclinical and clinical studies. This Review discusses the importance of tissue-specific ECM bioscaffolds and highlights the major advances that have been made in regenerative medicine strategies for the reconstruction of functional GI tissues.

Abstract
Biologic scaffold materials composed of allogeneic or xenogeneic extracellular matrix are commonly used for the repair and functional reconstruction of injured and missing tissues. These naturally occurring bioscaffolds are manufactured by the removal of the cellular content from source tissues while preserving the structural and functional molecular units of the remaining extracellular matrix (ECM). The mechanisms by which these bioscaffolds facilitate constructive remodeling and favorable clinical outcomes include release or creation of effector molecules that recruit endogenous stem/progenitor cells to the site of scaffold placement and modulation of the innate immune response, specifically the activation of an anti-inflammatory macrophage phenotype. The methods by which ECM biologic scaffolds are prepared, the current understanding of in vivo scaffold remodeling, and the associated clinical outcomes are discussed in this article.

Abstract
BACKGROUND Although many attempts have been made to advance the treatment of complex anal fistula, it continues to be a difficult surgical problem. This study aimed to describe the novel technique of video-assisted anal fistula treatment (VAAFT) and our preliminary experiences using VAAFT with patients with complex anal fistula. MATERIAL AND METHODS From May 2015 to May 2016, 52 patients with complex anal fistula were treated with VAAFT at Yangpu Hospital of Tongji University School of Medicine, and the clinical data of these patients were reviewed. RESULTS VAAFT was performed successfully in all 52 patients. The median operation time was 55 minutes. Internal openings were identified in all cases. 50 cases were closed with sutures, and 2 were closed with staplers. Complications included perianal sepsis in 3 cases and bleeding in another 3 cases. Complete healing without recurrence was achieved in 44 patients (84.6%) after 9 months of follow-up. No fecal incontinence was observed. Furthermore, a significant improvement in Gastrointestinal Quality of Life Index (GIQLI) score was observed from preoperative baseline (mean, 85.5) to 3-month follow-up (mean, 105.4; p<0.001), and this increase was maintained at 9-months follow-up (mean, 109.6; p<0.001). CONCLUSIONS VAAFT is a safe and minimally invasive technique for treating complex anal fistula with preservation of anal sphincter function.

Abstract
BACKGROUND The aim of this prospective study was to determine the efficiency of the Gore Bio-A synthetic plug in the treatment of anal fistulas. METHODS A synthetic bioabsorbable anal fistula plug was implanted in 60 patients. All fistulas were transsphincteric and cryptoglandular in origin. RESULTS The healing rate after 1 year of follow-up was 52 % (31 out of 60 patients). No patient was lost to follow-up. The treatment had no effect on the incontinence score. The plug dislodgement rate was 10 % (6 out of 60 patients). Thirty-four per cent of the patients (16 out of 47) required reoperation. The average operating time was 32 ± 10.2 min, and the average length of hospital stay was 3.3 ± 1.8 days. CONCLUSIONS Synthetic plugs may be an alternative to bioprosthetic fistula plugs in the treatment of transsphincteric anal fistulas. This method might have better success rates than treatment with bioprosthetic fistula plugs.

Abstract
AIM Several sphincter-preserving techniques have been described with extremely encouraging initial reports. However, more recent studies have failed to confirm the positive early results. We evaluate the adoption and success rates of advancement flap procedures (AFP), fibrin glue sealant (FGS), anal collagen plug (ACP) and ligation of intersphincteric fistula tract (LIFT) procedures based on their evolution in time for the management of anal fistula. METHOD A PubMed search from 1992 to 2015. An assessment of adoption, duration of study and success rate was undertaken. RESULTS We found 133 studies (5604 patients): AFP (40 studies, 2333 patients), FGS (31 studies, 871 patients), LIFT (19 studies, 759 patients), ACP (43 studies, 1641 patients). Success rates ranged from 0% to 100%. Study duration was significantly associated with success rates in AFP (P = 0.01) and FGS (P = 0.02) but not in LIFT or ACP. The duration of use of individual procedures since first publication was associated with success rate only in AFP (P = 0.027). There were no statistically significant differences in success rates relative to the number of the patients included in each study. CONCLUSION Success and adoption rates tend to decrease with time. Differences in patient selection, duration of follow-up, length of availability of the individual procedure and heterogeneity of treatment protocols contribute to the diverse results in the literature. Differences in success rates over time were evident, suggesting that both international trials and global best practice consensus are desirable. Further prospective randomized controlled trials with homogeneity and clear objective parameters would be needed to substantiate these findings.

Abstract
AIM This study aimed to review, consolidate and analyse the findings of studies investigating the efficacy of anal fistula plugs (AFPs) in treating fistula-in-ano in patients with Crohn's disease. METHOD A literature review was conducted via Pubmed, Embase, Medline, Scopus and the Cochrane Library for the period 1995-2015. Articles were selected and reviewed based on specific inclusion and exclusion criteria. RESULTS A total of 16 studies were extracted, of which 12 were included in the systematic review. In total, 84 patients (n = 1-20 per study) with a median age of 45 (18-72) years and a median follow-up time of 9 (3-24) months were analysed. The total success rate, defined as closure of the fistula tract, was 49/84 (58.3%, 95% CI 47-69). Success in patients with recurrent anal fistulae was 2/5 (40%, 95% CI 5-85). Overall, the success rates of Surgisis and GORE BIO-A brand plugs were 48/80 (60%, 95% CI 48-71) and 1/4 (25%, 95% CI 1-81). The recurrence rate of fistula-in-ano in the five studies that reported recurrence was 3/22 (13.6%). In two comparative studies, inferior overall success rates were found in patients who received preoperative immunomodulators vs. those who did not [3/11 (27.3%) vs. 17/23 (73.9%)]. CONCLUSION The studies suggest that the use of an AFP in patients with Crohn's disease is a safe procedure with reasonable success, little morbidity and a low risk of incontinence. The current literature is limited by a number of factors, including small study cohorts, grouping of fistulae in Crohn's disease with other types of anal fistula, short and highly variable follow-up times and multiple confounding factors such as number of fistula tracts, use of preoperative steroids or immunosuppressants, previous use of setons and variation in surgical technique.

Abstract
Despite recent progress in vascularized composite allotransplantation (VCA), limitations including complex, high dose immunosuppression regimens, lifelong risk of toxicity from immunosuppressants, acute and most critically chronic graft rejection, and suboptimal nerve regeneration remain particularly challenging obstacles restricting clinical progress. When properly configured, customized, and implemented, biomaterials derived from the extracellular matrix (ECM) retain bioactive molecules and immunomodulatory properties that can promote stem cell migration, proliferation and differentiation, and constructive functional tissue remodeling. The present paper reviews the emerging implications of ECM-based technologies in VCA, including local immunomodulation, tissue repair, nerve regeneration, minimally invasive graft targeted drug delivery, stem cell transplantation, and other donor graft manipulation.

Abstract
Introduction In a recent Cochrane review, the authors concluded that there is an urgent need for well-powered, well-conducted randomized controlled trials comparing various modes of treatment of fistula-in-ano. Ten randomized controlled trials were available for analyses: There were no significant differences in recurrence rates or incontinence rates in any of the studied comparisons. The following article reviews the studies available for treatment of fistula-in-ano with a fistula plug with special attention paid to the technique. Material and Methods PubMed, Medline, Embase, and the Cochrane medical database were searched up to July 2015. Sixty-four articles were relevant for this review. Results Healing rates of 50–60% can be expected for treatment of complex anal fistula with a fistula plug, with a plug-extrusion rate of 10–20%. Such results can be achieved not only with plugs made of porcine intestinal submucosa but also those made of other biological or synthetic bioabsorbable mesh materials. Important technical steps are firm suturing of the head of the plug in the primary opening and wide drainage of the secondary opening. Discussion Treatment of a complex fistula-in-ano with a fistula plug is an option with a success rate of 50–60% with low complication rate. Further improvements in technique and better studies are needed.

Abstract
Perianal sepsis is a common condition ranging from acute abscess to chronic fistula formation. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. The key to successful treatment is the eradication of the primary track. As surgery may lead to a disturbance of continence, several sphincter-preserving techniques have been developed. This consensus statement examines the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.

Abstract
BACKGROUND The aim of the present study was to assess a novel autologous cartilage plug technique used to treat anal fistula in ten patients. METHODS All ten patients had undergone at least two prior operations for recurrent fistulas. The plugs were prepared using the patients' own cartilage, which was obtained from either the nose or the ear, diced into pieces, and wrapped with oxidized regenerated cellulose. During the same session, fistula tracts were curetted using cytology brushes, and then, the cartilage plug was inserted into the tract. Routine postoperative examinations were performed at 2, 4, 8, 12, and 24 weeks after surgery. Magnetic resonance imaging was performed before surgery and at 3 and 6 months postoperatively. Relief of symptoms, radiological healing, recurrence, and continence were evaluated. RESULTS The ten patients included six males and four females, with a median age of 39 years (range 25-70 years) and a median of three previous fistula operations (range 2-7 operations). Nine patients had cryptoglandular abscess, and one patient had Crohn's disease. The majority of the patients had transsphincteric fistulas with substantial anal sphincter involvement. The cartilage donor site was the nose for one patient and the ear for nine patients. The median follow-up time was 24 months (range 10-32 months). Of the ten patients, nine had fistula treatment without any short-term complications. The fistula failed to heal in one patient. Among the nine patients whose operations were initially successful, two late recurrences were observed. CONCLUSIONS The cartilage plug seems to be a promising alternative for anal fistula treatment.

Abstract
BACKGROUND Although interest in sphincter-sparing treatments for anal fistulas is increasing, few large prospective studies of these approaches have been conducted. OBJECTIVE The study assessed outcomes after implantation of a synthetic bioabsorbable anal fistula plug. DESIGN A prospective, multicenter investigation was performed. SETTING The study was conducted at 11 colon and rectal centers. PATIENTS Ninety-three patients (71 men; mean age, 47 years) with complex cryptoglandular transsphincteric anal fistulas were enrolled. Exclusion criteria included Crohn's disease, an active infection, a multitract fistula, and an immunocompromised status. INTERVENTION Draining setons were used at the surgeon's discretion. Patients had follow-up evaluations at 1, 3, 6, and 12 months postoperatively. MAIN OUTCOME MEASURES The primary end point was healing of the fistula, defined as drainage cessation plus closure of the external opening, at 6 and 12 months. Secondary end points were fecal continence, duration of drainage from the fistula, pain, and adverse events during follow-up. RESULTS Thirteen patients were lost to follow-up and 21 were withdrawn, primarily to undergo an alternative treatment. The fistula healing rates at 6 and 12 months were 41% (95% CI, 30%-52%; total n = 74) and 49% (95% CI, 38%-61%; total n = 73). Half the patients in whom a previous treatment failed had healing. By 6 months, the mean Wexner score had improved significantly (p = 0.0003). By 12 months, 93% of patients had no or minimal pain. Adverse events included 11 infections/abscesses, 2 new fistulas, and 8 total and 5 partial plug extrusions. The fistula healed in 3 patients with a partial extrusion. LIMITATIONS The study was nonrandomized and had relatively high rates of loss to follow-up. CONCLUSION Implantation of a synthetic bioabsorbable fistula plug is a reasonably efficacious treatment for complex transsphincteric anal fistulas, especially given the simplicity and low morbidity of the procedure.

Abstract
Intensivists are often called upon to help care for patients who develop severe sepsis syndrome and septic shock where the primary source is an enterocutaneous fistula (ECF). The purpose of this article is to describe to the nonsurgeon intensivist how these complex surgical situations arise in the first place and provide the reader with a detailed understanding of the potentially devastating complications of ECF. In addition, we will describe a structured algorithm regarding the management of this often highly challenging surgical situation.

Abstract
Ideal surgical treatment for anal fistula should aim to eradicate sepsis and promote healing of the tract, whilst preserving the sphincters and the mechanism of continence. For the simple and most distal fistulae, conventional surgical options such as laying open of the fistula tract seem to be relatively safe and therefore, well accepted in clinical practise. However, for the more complex fistulae where a significant proportion of the anal sphincter is involved, great concern remains about damaging the sphincter and subsequent poor functional outcome, which is quite inevitable following conventional surgical treatment. For this reason, over the last two decades, many sphincter-preserving procedures for the treatment of anal fistula have been introduced with the common goal of minimising the injury to the anal sphincters and preserving optimal function. Among them, the ligation of intersphincteric fistula tract procedure appears to be safe and effective and may be routinely considered for complex anal fistula. Another technique, the anal fistula plug, derived from porcine small intestinal submucosa, is safe but modestly effective in long-term follow-up, with success rates varying from 24%-88%. The failure rate may be due to its extrusion from the fistula tract. To obviate that, a new designed plug (GORE BioA®) was introduced, but long term data regarding its efficacy are scant. Fibrin glue showed poor and variable healing rate (14%-74%). FiLaC and video-assisted anal fistula treatment procedures, respectively using laser and electrode energy, are expensive and yet to be thoroughly assessed in clinical practise. Recently, a therapy using autologous adipose-derived stem cells has been described. Their properties of regenerating tissues and suppressing inflammatory response must be better investigated on anal fistulae, and studies remain in progress. The aim of this present article is to review the pertinent literature, describing the advantages and limitations of new sphincter-preserving techniques.

Abstract
INTRODUCTION Enteric fistulas are a recognised complication of various diseases and surgical interventions. Non-operative medical management will result in closure of 60-70% of all fistulas over a six- to eight-week period, those that fail non-operative management will require operative intervention if they are to close. We present a series of upper gastrointestinal fistula managed with endoscopic intervention and insertion of biological fistula plug over a 3-year period across three Hospitals, both public and private, in Western Australia. METHODS Over a three-year period, 14 patients were referred for treatment of acute or persistent foregut fistulas. All fistulas were managed with endoscopic intervention and insertion of a porcine small intestine sub-mucosa plug (Biodesign (®) Cook medical Inc., Bloomington, IN, USA). No patients with fistula were excluded. Data were collected on patient demographics and underlying diagnosis. The biological plugs were deployed using three different endoscopic techniques (direct deployment via the endoscope, catheter-assisted endoscopic deployment, or a pull through via a guide wire using a rendezvous technique). RESULTS Fourteen patients with foregut fistula were treated using biological plugs. The age of the fistulas treated ranged from 14 days to 3 years. The fistulas were predominantly gastric in origin (eight cases). Three oesophageal, one gastro-pleural-bronchial, and two jejunal fistulas were also managed using this technique. Of the 14 fistulas treated using this method, 13 resolved following the treatment. Median time to closure of the fistula was 2 days (range 1-120 days). Three patients required more than one intervention to complete closure. CONCLUSION Biological plugs offer a further option for management of the traditionally difficult foregut fistula, without major morbidity associated with other treatment modalities. It is limited to the ability to deploy the plug endoscopically.

Abstract
AIM The Biodesign(®) anal fistula plug was introduced as a means of obliterating the fistula tract and promoting healing through biocompatibility. The results demonstrated unexplained variations from good to bad. This report analysed the results of a retrospective multicentre study. METHOD All plug procedures performed in four Stockholm hospitals between June 2006 and June 2010 were identified and studied using a common protocol. The outcome after the first plug-insertion procedure was assessed by chart review performed a minimum of 8 months after plug insertion. Cox proportional-hazards models were used to assess the associations of various factors with fistula healing. RESULTS One-hundred and twenty-six patients (mean age 47 years) were deemed suitable for the plug procedure. Eighty-five per cent of fistulae were cryptoglandular, 64% of patients were male and a mean of 2.9 previous fistulae procedures had been performed. All patients, except four, had an indwelling seton at the time of the plug procedure, which was performed in accordance with previously established principles of day surgery. After a median of 13 months, 30 (24%) fistulae had closed with no discomfort or secretion reported. The outcome in the four hospitals varied from 13% to 33% with similar numbers of patients in each hospital. A success rate of 12% was observed for patients with anterior fistula compared with 32% for those with posterior tracks [hazard ratio (HR) for successful healing = 2.98; 95% CI: 1.01-8.78) and 41% for those with a lateral internal opening (HR = 3.76; 95% CI: 1.03-13.75). Age, sex and number of previous procedures were not associated with healing. CONCLUSION Four independent patient groups showed low success rates after the first plug-insertion procedure. Anterior fistulae were much less likely to heal compared with fistulae in other locations.

Köckerling F, von Rosen T, Jacob D. Modified plug repair with limited sphincter sparing fistulectomy in the treatment of complex anal fistulas. Front Surg 2014; 1:17.

Abstract
PURPOSE New technical approaches involving biologically derived products have been used to treat complex anal fistulas in order to avoid the risk of fecal incontinence. The least invasive methods involve filling out the fistula tract with fibrin glue or introduction of an anal fistula plug into the fistula canal following thorough curettage. A review shows that the new techniques involving biologically derived products do not confer any significant advantages. Therefore, the question inevitably arises as to whether the combination of a partial or limited fistulectomy, i.e., of the extrasphincteric portion of the fistula, and preservation of the sphincter muscle by repairing the section of the complex anal fistula running through the sphincter muscle and filling it with a fistula plug produces better results. METHODS A modified plug technique was used, in which the extrasphincteric portion of the complex anal fistula was removed by means of a limited fistulectomy and the remaining section of the fistula in the sphincter muscle was repaired using the fistula plug with fixing button. RESULTS Of the 52 patients with a complex anal fistula, who had undergone surgery using a modified plug repair with limited fistulectomy of the extrasphincteric part of the fistula and use of the fistula plug with fixing button, there are from 40 patients (follow-up rate: 77%) some kind of follow-up informations, after a mean of 19.32 ± 6.9 months. Thirty-two were men and eight were women, with a mean age of 52.97 ± 12.22 years. Surgery was conducted to treat 36 transsphincteric, 1 intersphincteric, and 3 rectovaginal fistulas. In 36 of 40 patients (90%), the complex anal fistulas or rectovaginal fistulas were completely healed without any sign of recurrence. None of these patients complained about continence problems. CONCLUSION A modification of the plug repair of complex anal fistulas with limited fistulectomy of the extrasphincteric part of the fistula and use of the plug with fixing button seems to increase the healing rate in comparison to the standard plug technique.

Abstract
Symptoms thought related to hemorrhoids must be carefully considered before intervention. The first line of therapy for any hemorrhoidal complaint remains conservative management with increased fluid and fiber intake and appropriate modification of toileting behavior. Bleeding in grades 1 and 2 hemorrhoids that does not respond to this can be satisfactorily and safely managed with office-based therapies; some grade 3 hemorrhoids would also respond to this, though more treatment sessions would likely be required. Operative therapy is the best choice for management of persistently symptomatic grade 2 disease and for grades 3 and 4 symptomatic hemorrhoids as well. With proper patient selection and preparation, along with a familiarity with instrumentation and techniques, good results can be obtained with newer operative interventions for internal hemorrhoids. Outcomes must always be compared with those obtained with classic excisional hemorrhoidectomy.

Short-Term Outcomes of KeraSys Patch Graft for Glaucoma Drainage Devices: A Case Series. J Ophthalmol 2013; 2013:784709. [PMID: 23577238 PMCID: PMC3613091 DOI: 10.1155/2013/784709] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2013] [Accepted: 02/14/2013] [Indexed: 11/26/2022] Open
Abstract
Purpose. Tube-related exposure is a known complication of glaucoma drainage device (GDD) surgery. Our objective is to report the early (approximately 1 year) tube exposure rate of implants covered with a keraSys (IOP Inc., Costa Mesa, CA, USA) tissue reinforcement graft. Patients and Methods. A retrospective, noncomparative, consecutive case series of 42 eyes with GDD implantation with keraSys patch grafts was performed. Main outcome measurements included patch-related complications: patch exposure, tube exposure, wound dehiscence, and patch migration. Results. Forty-two eyes were followed for an average of 15.24 ± 10.44 months (range 1.0–32.3 months). Four (10%) eyes experienced patch-related complications: two with exposure 8 months postoperatively, one with exposure 13 months postoperatively, and one with exposure 4 weeks postoperatively. Conclusion. The effectiveness of the keraSys patch graft is limited by the higher than expected early exposure rate found in this case series. These results should be confirmed in other studies.
