Abstract
BACKGROUND An enterocutaneous fistula (ECF) is defined as an abnormal communication between the gastrointestinal tract and skin. ECFs are rarely encountered in clinical practice, yet are frequently difficult to treat. Few reports exist regarding the surgical techniques for the treatment of an ECF. Therefore, we report a case of refractory ECF with concomitant severe adhesions, in which we performed combined laparoscopic adhesiolysis and planned open conversion. CASE PRESENTATION A 57-year-old female patient underwent a laparotomy for an ovarian cyst in her 20s. At 46 years, adhesiolysis without bowel resection was performed for adhesive small bowel obstruction (SBO). However, her symptoms did not improve. Eighteen days postoperatively, she underwent a reoperation and jejunostomy. An ECF developed post-reoperation; therefore, stoma closure and radical surgery for the ECF were planned. Due to the severe adhesions, only stoma closure was performed, based on intraoperative assessments. The patient was subsequently referred to our hospital. First, skin care around the fistula was provided during an outpatient visit. Appropriate sizing of the stoma pouch was performed, to improve erosions and ulcers. Thereafter, debridement of the perifistula skin and simple closure of the ECF outlet were attempted; however, the ECF recurred shortly thereafter. After 8 years of regular skin care, with the ECF remaining stable, however, manifesting as symptomatic SBO, she underwent laparoscopic adhesiolysis. This procedure was initiated in the epigastric region, where relatively fewer adhesions were anticipated. Post-open conversion, partial resection of the small intestine at four locations, including the fistula site, was performed. Postoperatively, jejunal edema and peristaltic dysfunction, due to narrowing of the superior mesenteric artery occurred. Regular drainage by percutaneous endoscopic gastrostomy was required. However, she improved and was discharged 3 months post-operatively. Three years post-operatively, the ECF and SBO did not recur. CONCLUSIONS We reported a case of refractory ECF in which we were able to safely perform surgery, by combining laparoscopic adhesiolysis and a planned open conversion. Therefore, the surgical approach used in this case may be an option for securing a safe surgical field, while avoiding collateral damage.

Treatment of enterocutaneous fistula: a systematic review and meta-analysis. Tech Coloproctol 2022; 26:863-874. [PMID: 35915291 DOI: 10.1007/s10151-022-02656-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Accepted: 06/20/2022] [Indexed: 10/16/2022]
Abstract
BACKGROUND Enterocutaneous fistula (ECF) is an abnormal communication between the gastrointestinal tract and skin, with a myriad of etiologies and therapeutic options. Management is influenced by etiology and specifics of the ECF, and patient-related factors. The aim of this study was to assess overall success, recurrence, and mortality rates of treatment for ECF. MATERIALS A systematic search of PubMed and Google Scholar was performed through October 2021 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Case reports, reviews, animal studies, studies not reporting outcomes, had no available English text, included patients < 16 years old or those assessing other abdominocutaneous/internal fistulas were excluded. RESULTS Fifty-three studies, between 1975 and 2020, incorporating 3078 patients were included. Patient age ranged between 16 and 87 years with a male:female ratio of 1.14:1. ECF developed postoperatively in 89.4%. Other common etiologies were inflammatory bowel disease, trauma, malignancy, and radiation. At least 28% of patients had complex fistulae (reported in 18 studies). Most common fistula site was small bowel. In 34 publications, 62.4% (n = 1371) patients received parenteral nutrition. In 45 publications, 72.5% underwent surgery to treat the fistula. Meta-analysis revealed an 89% healing rate; recurrence rate after initial successful treatment was 11.1%, and mortality rate was 8.5%. In a subgroup of patients who underwent combined ECF takedown and abdominal wall reconstructions (n = 315), 78% achieved fascial closure, mesh was used in 72%, hernia, and fistula recurrence rates were 19.7% and 7.6%, respectively. CONCLUSIONS Treatment of ECF must be individualized according to specific etiology and location of the fistula and the patient's associated conditions.

Failure to Rescue (FTR) and Pitfalls in the Management of Complex Enteric Fistulas (CEF): From Rescue Surgery to Rescue Strategy. J Pers Med 2022; 12:jpm12020292. [PMID: 35207780 PMCID: PMC8875978 DOI: 10.3390/jpm12020292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 02/14/2022] [Accepted: 02/15/2022] [Indexed: 11/16/2022] Open
Abstract
Purpose: Complex enteric fistulas (CEF) represent general surgeons’ nightmare. This paper aims to explore the impact on failure-to-rescue (FTR) rate of a standardised and integrated surgical and critical care step-up approach. Methods: This was a retrospective observational cohort study. Patients treated for CEF from 2009 to 2019 at Niguarda Hospital were included. Each patient was approached following a three-step approach: study phase, sepsis control and strategy definition phase, and surgical rescue phase. Results: Sixteen patients were treated for CEF. Seven fistulas were classified as complex entero-cutaneous (ECF) and nine as entero-atmospheric fistula (EAF). Median number of surgical procedures for fistula control before definitive surgical attempt was 11 (IQR 2–33.5). The median time from culprit surgery and the first access at Niguarda Hospital to definitive surgical attempt were 279 days (IQR 231–409) and 120 days (IQR 34–231), respectively. Median ICU LOS was 71 days (IQR 28–101), and effective hospital LOS was 117 days, (IQR 69.5–188.8). Three patients (18.75%) experienced spontaneous fistula closure after conversion to simple ECF, whereas 13 (81.25%) underwent definitive surgery for fistula takedown. Surgical rescue was possible in nine patients. Nine patients underwent multiple postoperative revision for surgical complications. Four patients failed to be rescued. Conclusion: An integrated step-up rescue strategy is crucial to standardise the approach to CEF and go beyond the basic surgical rescue procedure. The definition of FTR is dependent from the examined population. CEF patients are a unique cluster of emergency general surgery patients who may need a tailored definition of FTR considering the burden of postoperative events influencing their outcome.

The management of postoperative upper alimentary tract fistulas: A single-center experience of endoscopic tissue glue repair and recommendations of a systematic review. J Formos Med Assoc 2022; 121:1204-1214.

Abstract
BACKGROUND/PURPOSE The appropriate management of postoperative upper alimentary tract fistula (UATF) remains uncertain. The efficacy of esophagogastroduodenoscopy (EGD) tissue glue repair in the treatment of patients with postoperative UATF was explored. We also conducted a systematic review of the literature regarding the inpatient management of UATF. METHODS Totally 24 patients received EGD tissue glue repair for postoperative UATF at our institute from April 2014 to April 2020. Independent characteristics of size of fistula, location of the UATF, complications, and recurrences were analyzed. PubMed and Cochrane Library databases were reviewed. A pooled analysis was performed, and subgroup analysis was conducted separately for different anatomic locations and techniques. RESULTS With a mean follow-up of 40 months, the fistula failed to close with EGD tissue glue repair in 2 of 24 patients (8.3%). Eight patients required repeated EGD tissue glue repair, which was more frequent in oral or thoracic UATF (p = 0.053), but all achieved a successful seal in the EGD tissue after glue repair alone (n = 22). The fistula size was correlated with the demand for repeated EGD tissue glue repair (p = 0.017). Besides, a total of 30 studies regarding 2356 cases of postoperative UATF between 2010 and 2021 were retrieved and analyzed. Several non-operative methods were generally accepted as the initial approach, with a non-inferior success rate compared to operative techniques. CONCLUSIONS The results suggest that no single approach toward UATF is superior in terms of success rate and healing time. The potential advantages of EGD tissue glue repair after drainage were more suitable for patients with postoperative UATF and multiple comorbidities.

Abstract
Recent advancement in endoscopic closure techniques have revolutionized the treatment of gastrointestinal perforations, leaks and fistulas. Traditionally, these have been managed surgically. The treatment strategy depends on the size and location of the defect, degree of contamination, presence of healthy surrounding tissues, patients' condition and the availability of expertise. One of the basic principles of management includes providing a barricade to the flow of luminal contents across the defect. This can be achieved with a wide range of endoscopic techniques. These include endoclips, stenting, suturing, tissue adhesives and glue, and endoscopic vacuum therapy. Each method has their distinct indications and shortcomings. Often, a combination of these techniques is required. Apart from endoscopic closure, drainage procedures by the interventional radiologist and surgical management also play an important role. In this review article, the outcomes of each of these endoscopic closure techniques in the literature is provided in tables, and practical management algorithms are being proposed.

Abstract
The management of enterocutaneous fistulas (ECF) can be challenging because of massive fluid loss, which can lead to electrolyte imbalance, severe dehydration, malnutrition and sepsis. Nutritional support plays a key role in the management and successful closure of ECF. The principle of nutritional support for patients with ECF should be giving enteral nutrition (EN) priority, supplemented by parenteral nutrition if necessary. Although total parenteral nutrition (TPN) may be indicated, use of enteral feeding should be advocated as early as possible if patients are tolerant to it, which can protect gut mucosal barrier and prevent bacterial translocation. A variety of methods of enteral nutrition have been developed such as fistuloclysis and relay perfusion. ECF can also be occluded by special devices and then EN can be implemented, including fibrin glue application, Over-The-Scope Clip placement and three-dimensional (3D)-printed patient-personalized fistula stent implantation. However, those above should not be conducted in acute fistulas, because tissues are edematous and perforation could easily occur.

Abstract
Background. Esophagogastroduodenoscopy (EGD) is an important tool in the evolving specialty of acute care surgery (ACS). Understanding the types of nonelective EGDs performed by ACS groups is important for the development of ACS programs and the training of future general surgeons. Methods. We conducted a retrospective review of all EGDs performed by ACS surgeons at a single urban academic center over a 5-year period (January 2013-December 2018). Results. A total of 495 EGDs were performed, of which 129 (26%) were urgent, nonelective procedures. Patients who underwent urgent EGD were younger than those who underwent elective procedures (median 55 vs 60 years, P = .03), had higher American Society of Anesthesiologists (ASA) classes (median ASA 3 vs 2, P = .0002), and longer hospital stays (median 5 days vs 0 days, P < .0001). The most common indications for urgent endoscopies were the management of leak, dysphagia, or stenosis in patients with a history of foregut surgery, followed by the management of esophageal perforation. The success rate of endoscopic therapy was high (median 88%, interquartile range (IQR) 78-89%). However, some patients required multiple interventions (median 1, IQR 1-3), and patients treated for leaks were less likely to be successfully treated with endoscopic therapy alone than patients treated for other indications (success rate 65% vs 88%, P = .003). Conclusions. Our experience suggests that EGD has an important role in current ACS practice and that endoscopic management is safe and effective in a range of urgent surgical scenarios. Future ACS surgeons should be facile with endoscopic techniques.
