A method for treatment of deep and superficial enteroatmospheric fistulas in an open abdomen, ChimneyVAC: Ten years experience.

BACKGROUND: Leakage of intestinal fluid is a challenging event when it appears in an open abdomen (OA) and surgical deviation does not seem possible. Intestinal contents in the abdominal cavity maintain inflammation and drainage is there for essential. We have developed a method, ChimneyVAC, to treat both deep and superficial enteroatmospheric fistulas (EAF) AIMS: To describe this innovative surgical technique and our 10-year experience. MATERIAL & METHODS: This single-center observational cohort study included all 16 consecutive patients treated with ChimneyVAC. Seven women and 9 men; median age: 47; (interquartile range [IQR]:39-63) years, 15 with a small bowel fistula and 1 with a large bowel fistula. All except of the colonic fistula were classified as a high output fistula; 14 were deep and 2 superficial. In this technique, a negative-pressure source is applied directly above the fistula opening, in addition to negative pressure wound therapy for the OA. This controls the leakage of intestinal fluid by direct drainage into a vacuum system, thereby avoiding contamination of the abdomen. A controlled enterocutaneous fistula (ECF) then forms as the traction from the ChimneyVAC brings the fistula opening to skin level. RESULTS: In 14 patients, an ECF formed after a median of 42 (IQR:28-55) days and 12 (IQR:7-16) dressing changes. The median length of hospitalization was 103 (IQR:58-143) days. Two patients died of multiorgan failure and 14 initially survived. DISCUSSION: This study showed that 14 out of 16 patients survived the initial treatment for enteric leakage with the ChimneyVAC method. The outcome of ChimneyVAC treatment is a controlled ECF, which was then corrected after a median of six months. However, hospitalization is lengthy, the patients undergo several dressing changes and many needs additional parenteral nutrition until intestinal continuity is reestablished. CONCLUSION: ChimneyVAC is a feasible method for treatment of EAF in an OA, with favorable survival.

Putting life on hold: A longitudinal phenomenological-hermeneutic study of living with [or close to someone with] an enterocutaneous fistula before and after reconstructive surgery.

AIMS AND OBJECTIVES: Illuminate meanings of living with [or close to someone with] an enterocutaneous fistula before and after reconstructive surgery. BACKGROUND: Enterocutaneous fistula is a serious condition affecting the well-being and social life of both patients and families, sometimes for several years. DESIGN: A longitudinal qualitative design. METHODS: Patients and families (n = 14) were followed with dyadic interviews at three occasions, conducted 2017-2020. The interviews were analysed with a phenomenological-hermeneutic approach. COREQ guidelines were followed. RESULT: Living with an enterocutaneous fistula was explained as life being put on hold, while living in a bubble for an uncertain time. This bubble meant facing an unpredictable and restricted life where the dyads were forced to take control over the situation despite being vulnerable inside, striving to resume normality. The patients dealt with never-ending symptoms such as leakage from the fistula, pain and fatigue, while the family supported with practical matters and just being close. Dependency on intravenous fluids resulted in social isolation, which caused mode swings and depressiveness. In this situation, healthcare professionals often became a substitute for other interactions, but the lack of understanding about the dyads' situation, affected their trust in the healthcare. Despite all, they still had belief in the future, the patients having higher expectations than the family. CONCLUSIONS: Living with an enterocutaneous fistula meant a daily life struggling with many limitations. This implies that the transition was associated with difficulties and the dyads strived to accept their situation. RELEVANCE TO CLINICAL PRACTICE: The findings indicate that these patients must be cared for with a multidisciplinary approach. A person-centred health plan could impact on the dyads' feeling of control and thereby making them less dependent on healthcare. Every patient should have their own contact nurse and be offered psychological support. NO PATIENT OR PUBLIC CONTRIBUTION: Not applicable due to the current method.

Risk factors for refractory enterocutaneous fistula following button jejunostomy removal and its treatment using a novel extraperitoneal approach in patients with oesophageal cancer: a retrospective cohort study.

BACKGROUND: Enterocutaneous fistula after removal of the jejunostomy tube leads to multiple problems, such as cosmetic problems, decreased quality of life, electrolyte imbalances, infectious complications, and increased medical costs. However, the risk factors for refractory enterocutaneous fistula (REF) after button jejunostomy removal remain unclear. Therefore, in this study, we assessed the risk factors for REF after button jejunostomy removal in patients with oesophageal cancer and reported the surgical outcomes of the novel extraperitoneal approach (EPA) for REF closure. METHODS: This retrospective cohort study included 47 patients who underwent button jejunostomy removal after oesophagectomy for oesophageal cancer. We assessed the risk factors for REF in these patients and reported the surgical outcomes of the novel EPA for REF closure at the International University of Health and Welfare Hospital between March 2013 and October 2021. The primary endpoint was defined as the occurrence of REF after removal of the button jejunostomy, which was assessed using a maintained database. The risk factors and outcomes of the EPA for REF closure were retrospectively analysed. RESULTS: REFs occurred in 15 (31.9%) patients. In the univariate analysis, REF was significantly more common in patients with albumin level < 4.0 g/dL (p = 0.026), duration > 12 months for button jejunostomy removal (p = 0.003), and with a fistula < 15.0 mm (p = 0.002). The multivariate analysis revealed that a duration > 12 months for button jejunostomy removal (odds ratio [OR]: 7.15; 95% confidence interval [CI]: 1.38-36.8; p = 0.019) and fistula < 15.0 mm (OR: 8.08; 95% CI: 1.50-43.6; p = 0.002) were independent risk factors for REF. EPA for REF closure was performed in 15 patients. The technical success rate of EPA was 88.2%. Of the 15 EPA procedures, fistula closure was achieved in 12 (80.0%). The complications of EPA (11.7%) were major leakages (n = 3) and for two of them, EPA procedure was re-performed, and closure of the fistula was finally achieved. CONCLUSION: This study suggested that duration > 12 months for button jejunostomy removal and fistula < 15.0 mm are the independent risk factors for REF after button jejunostomy removal. EPA for REF closure is a novel, simple, and useful surgical option for patients with REF after oesophagectomy.

Treatment of enterocutaneous fistula: a systematic review and meta-analysis.

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.

Enterocutaneous Fistula: Open Repair after Unsuccessful Stenting-A Case Report.

Enterocutaneous fistula (ECF) is an abnormal connection between the gastrointestinal tract and the skin; by some estimates, it represents 88.2% of all fistulae. It can either develop spontaneously due to underlying malignancy, inflammatory bowel disease, radiation exposure, or, more commonly, as a complication of gastrointestinal surgery. A 75-year-old woman was treated for a small bowel enterocutaneous fistula that developed after laparoscopic cholecystectomy using a HANAROSTENT self-expanding metal stent (SEMS) to cover the fistula. Seven months later, the patient was discharged. For the following 2 years, the patient refused the reconstructive surgery until stent obstruction occurred. After optimizing the patient's nutritional status, laparotomy and small bowel resection were performed successfully. The use of SEMS in fistulas of the lower gastrointestinal tract is a heavily debated and fairly under-researched topic, especially in the context of enterocutaneous fistulas. No international guidelines officially recommend using SEMS in the small bowel ECF.

Complexities in the management of a Richter's supraumbilical hernia with colocutaneous fistula in a patient with morbid obesity: A case report with a review of literature.

Abdominal wall Richter's hernia is rare. The usual presentation is with irreducibility, obstruction and strangulation. Occasionally, enterocutaneous fistula containing small bowel has been reported. Management is frequently difficult due to emergency presentation and contamination. A 60-year-old male with a history of suture repair of umbilical hernia presented with faecal discharge from a long-standing recurrent hernia in the background of obesity and history of pulmonary embolism. There were no features of peritonitis or obstruction. After optimisation, we took the patient for a diagnostic laparoscopy with curative intent. Diagnostic laparoscopy revealed a Richter's hernia containing transverse colon. The patient was treated with resection of the involved colonic segment, anastomosis, complete excision of the fistula tract along with surrounding skin, negative pressure wound therapy and delayed skin closure. To our knowledge, this is the first report of a spontaneous umbilical Richter's hernia complicated with a colocutaneous fistula. Management was challenging due to emergency presentation, multiple comorbidities as well as faecal contamination. Minimal access approach may have helped by decreasing the contamination and surgical site infection in the postoperative period.

[Surgical treatment of enterocutaneous fistulas in patients with ventral incisional hernia]. / Khirurgicheskoe lechenie naruzhnykh kishechnykh svishchei v posleoperatsionnykh gryzhakh.

OBJECTIVE: To determine the optimal surgical treatment in patients with enterocutaneous fistulas combined with ventral incisional hernia. MATERIAL AND METHODS: There were 24 patients with enterocutaneous fistulas combined with ventral incisional hernia. Enterocutaneous fistula was noted in 19 cases, enteroatmospheric fistula - in 5 patients. RESULTS: Simultaneous fistula closure and abdominal wall repair were performed in 14 patients (mesh repair in 5 cases and local approximation of tissues in 9 cases). Postoperative complications occurred in 8 patients, hernia recurrence in long-term period developed in 7 people. Two-stage closure of abdominal wall defect was carried out in 10 patients. Fistula closure was followed by edge-to-edge anterior abdominal wall repair in 5 cases, skin edges were approximated by interrupted sutures or open wound management was performed. There were no postoperative complications and hernia recurrence in this group. CONCLUSION: Surgical treatment of patients with enterocutaneous fistulas combined with hernia should be performed in two stages, i.e. enterocutaneous fistula closure with subsequent hernia repair.

Assessment of button-type jejunostomy for nutritional management after esophagectomy in 201 cases.

BACKGROUND: Many surgeons preferably place a trans-nasal feeding tube or a feeding enterostomy for post-operative nutritional management after esophagectomy. Various types of tubes (such as nasogastric, transgastric, transduodenal, or transjejunal tubes) have been used for enteral feeding; however, the appropriate enteral feeding routes have not yet been proposed. Therefore, this study aimed to evaluate the feasibility and safety of button-type jejunostomy. METHODS: We reviewed 201 patients who underwent esophagectomy with placement of a button-type jejunostomy at the Jikei University Hospital (Tokyo, Japan) between 2008 and 2019. The analyzed variables included clinicopathological characteristics, operative data, jejunostomy-related characteristics, and postoperative complications. Postoperative bodyweight loss was examined 6 months and 1 year after the operation. RESULTS: Refractory enterocutaneous fistula and bowel obstruction occurred in 13 (6.5%) and 14 (7.0%) patients, respectively. The body mass index at button-type jejunostomy removal was significantly lower and the duration of button-type jejunostomy placement was significantly longer in patients with a refractory enterocutaneous fistula (p = 0.023 and p < 0.001, respectively). Bowel obstruction was significantly more likely to develop in patients with a non-squamous cell carcinoma (p = 0.021) and in patients who underwent open abdominal procedures (p < 0.001). After 1 year, the median bodyweight losses were 12.1% and 15.6% in patients with short and long jejunostomy placement durations (p = 0.642), respectively. CONCLUSION: A button-type jejunostomy is durable and allows easy self-management for maintaining the bodyweight without any adverse events. However, it is strongly recommended that the button be removed within a year to prevent refractory enterocutaneous fistula formation.

Spontaneous enterocutaneous fistula in a patient with femoral hernia: a case report.

BACKGROUND: Enterocutaneous fistula commonly occurs in the post-operative setting. However, a handful of cases have been reported to occur secondary to strangulation of hernia, mostly femoral due to the narrow femoral ring through which this type of hernia passes through. CASE PRESENTATION: We encountered a case of spontaneous fecal fistula, which occurred in the setting of an incarcerated femoral hernia. The patient did not develop peritonism, or obstruction, throughout the course of the disease. The hernia ruptured on day 7 of incarceration. Exploratory laparotomy under epidural anesthesia revealed a femoral hernia with ileum as content, arising approximately 20 cm from the ileocecal junction. Reduction of the contents was done, and a resection performed along with repair of the hernia. CONCLUSION: As very few literature describe the formation of spontaneous fecal fistula, we discuss the presentation in this report.

Lessons learned from successful autologous gastrointestinal reconstruction in patients with intestinal failure: a case series.

BACKGROUND: Intestinal failure (IF) is a rare but severe form of organ failure. The condition is defined as body's inability to absorb adequate fluids, macronutrients and minerals for growth and development, so that intravenous supplementation is necessary. A broad spectrum of diseases, trauma and complications of surgery might eventually end up with intestinal failure. Nowadays, intestinal failure patients are preferably cared for in intestinal rehabilitation units (IRU). Autologous gastrointestinal reconstruction (AGIR) refers to non-transplant operative management of IF patients designed to improve enteral tolerance and gut absorptive capacity. CASE PRESENTATION: Herein we present five cases with complications of surgeries due to peptic ulcer bleeding, blunt abdominal trauma, obesity and gastric tumor. The surgeries were complicated by anastomotic leak, peritonitis and fistula formation. By adopting multidisciplinary decisions and special care for each complication, all the five patients were successfully managed and discharged. DISCUSSION AND CONCLUSIONS: As presented, re-anastomosis in presence of abdominal contamination will probably fail. In patients with intestinal failure, PN should start as soon as possible to increase the success rate of future surgeries and prevent potential need for intestinal transplantation. We suggest referring patients with complicated outcomes of gastrointestinal surgeries to the IRUs to reduce morbidity and mortality.

Serial transverse enteroplasty and nipple valve construction, two life saving techniques for patients with short bowel syndrome, a report of 5 cases.

BACKGROUND: Various abdominal pathologies end up with surgical resection of small intestine. When the small intestine remnant is too short for adequate fluid and micronutrients absorption, short bowel syndrome is diagnosed. The disabling condition needs a multidisciplinary approach to design parenteral nutrition, care for thrombotic, hepatic and infectious complications and gradually wean the patient from parenteral nutrition. Various surgical techniques have been introduced to increase absorptive mucosa and enhance the intestinal adaptation process. Serial transverse enteroplasty and nipple valve reconstruction are among the procedures, which will be discussed in the current article. CASE PRESENTATION: Herein, we presented 5 cases of short bowel syndrome as a consequence of abdominal laparotomies, patients were referred to our center to receive parenteral nutrition and to be prepared for the final autologous gastrointestinal reconstruction or intestinal transplantation, if indicated. CONCLUSION: Patient's age, performance status and bowel remnant length determines the appropriate technique for autologous gastrointestinal reconstruction. Serial transverse enteroplasty is designed to increase bowel's length by creating zigzag patterns through dilated bowel loops. Presence of ileocecal valve is crucial to delay intestinal transit time and to prevent colonic bacterial transfer to ileum. Patient's with ileocecal valve loss benefit from creating an artificial valve, namely, nipple valve.

Gastrointestinal Stomas and Fistulas: What is Lost and What to Do?

Abnormal connections between gastrointestinal tract (GIT) and skin are called enterocutaneous fistulas (ECFs). Presence of ECF is associated with significant morbidity and mortality. A stoma refers to a surgically created opening in the abdomen to divert feces or urine to the outside of the body, to compensate for partial or complete loss of bowel function. Gastrointestinal (GI) stomas and postoperative ECFs present a unique challenge to the intensivist due to development of malnutrition, dehydration, and sepsis leading to high morbidity and mortality. This review focuses on the basic concepts about the type of fistula and stomas, their indications and complications, and management. Principles of clinical management include replacement of fluid and electrolyte losses, control of sepsis along with reducing fistula output, prevention of malnutrition and psychological support, and skin care.

[Staged approach in the treatment of patients with enterocutaneous fistulae]. / Etapnyi podkhod v lechenii bol'nykh s nesformirovannymi kishechnymi svishchami.

OBJECTIVE: To determine an optimal approach in the treatment of patients with intestinal fistulae. MATERIAL AND METHODS: We have used the above-mentioned algorithm in the treatment of 46 patients. The majority of patients (n=44, 96%) were transferred under supervision of our multidisciplinary team with severe water-electrolyte disturbances and signs of secondary protein-energy malnutrition (PEM) that required complex combined nutritional support. A two-stage approach was applied in all cases. The first one was conservative and included correction and prevention of infectious complications, nutritional and metabolic therapy, local wound treatment, and anatomical assessment of the fistula. The second stage was reconstructive and implied various reconstructive interventions not earlier than 3 months after formation of the fistula. RESULTS: Conservative approach was followed by fistula healing in 6 patients, surgery was required in 25 patients. Complications with subsequent redo surgery occurred in 4 cases. In all cases, favorable outcome was noted. All 25 patients were discharged. Three patients refused reconstructive surgery after development of fistula, they were also discharged. Mortality rate was 26% (n=12). CONCLUSION: A multidisciplinary two-stage approach can significantly improve treatment outcomes in patients with intestinal fistulae.

Enterocutaneous fistula in severely active Crohn's disease: preoperative anti-TNF alpha treatment to limit bowel resection-report of a case.

PURPOSE: Strategies for limiting the extent of bowel resection in cases of enterocutaneous or interenteric fistulas in severely active Crohn's disease are urgently necessary. Anti-inflammatory therapy with tumor necrosis factor alpha (anti-TNF alpha) inhibitors has positive impact on fistulizing Crohn's disease. We describe a case of a 32-year-old male suffering from enterocutaneous fistula in severely active Crohn's disease. METHODS: The patient's clinical course and data of therapy monitoring before bowel resection were reviewed and compared to the pretherapeutic findings. In addition, the reports of surgery and histopathological workup were evaluated and a clinical follow-up was performed. The literature on anti-TNF alpha treatment in fistulizing Crohn's disease was surveyed. RESULTS: A 32-year-old male with an 8-year history of Crohn's disease and condition after previous ileocecal and sigmoid resection at the age of 28 presented with increasing pain in the middle-right abdomen. Laboratory and radiologic assessment detected elevated C-reactive protein and presence of a conglomerate of inflammatory thickened and narrowed small intestine involving the neoterminal ileum and enteroenteric fistulas. Ileocolonoscopy showed a stenosing inflammation of the neoterminal ileum. After initial anti-infective therapy, as a result of an interdisciplinary decision, preoperative anti-TNF alpha treatment was performed to achieve limited bowel resection. After declining of inflammation, limited bowel resection was carried out successfully. CONCLUSIONS: Preoperative therapy with anti-TNF alpha might potentially reduce inflammation to subsequently limit the extent of bowel resection in selected cases of enterocutaneous or interenteric fistulas in severely active Crohn's disease. We describe an impressive case in which such therapeutic approach was carried out.

Incisional hernia and enterocutaneous fistula in patients with chronic intestinal failure: prevalence and risk factors in a cohort of patients referred to a tertiary centre.

AIM: This study aims to determine the prevalence of incisional hernia (IH) and enterocutaneous fistula (ECF) in patients with intestinal failure (IF) referred to a tertiary centre and to identify factors associated with their development. METHOD: A retrospective case note review was undertaken of a prospectively maintained database of all patients on home parenteral nutrition between 2011 and 2016 at a UK tertiary referral centre for IF. Risk factors were identified using binary logistic regression. RESULTS: The database search identified 447 patients, of whom 349 (78.1%) had surgery prior to developing IF. Eighty-one (23.2%) patients had an IH and 123 (35.2%) had an ECF at the time of referral. Of these, 51 (14.6%) had both IH and ECF. IH was associated with a high body mass index (P = 0.05), a history of a major surgical complication resulting in IF (P = 0.01), previous emergency surgery (P = 0.04), increasing number of operations (P = 0.02) and surgical site infection (SSI; P = 0.01). ECF was associated with complications relating to earlier surgery. (P ≤ .001), previous treatment with an open abdomen (P = 0.03), SSI (P = 0.001), intra-abdominal collection (P ≤ 0.001) and anastomotic leak (P = 0.02). CONCLUSION: In this series, patients with IF had a prevalence of IH which was more than double that expected following elective laparotomy (about 10%) and one in three had an ECF. Risk factors for IH and ECF are discussed.

Endoscopic technique for closure of enterocutaneous fistulas.

BACKGROUND AND OBJECTIVES: Endoscopic over the scope clip (OTSC) closure represents a new technique for endoscopic management of enteric bleeding and tissue defects such as anastomotic leaks and enterocutaneous (EC) fistulas. We aim to describe our technical approach for OTSC closure of EC fistulas and convey our outcomes. METHODS AND PROCEDURES: This retrospective review includes ten patients who underwent OTSC application for EC fistulas by surgical endoscopists at a US tertiary care hospital from July 2015 to October 2017. Demographic data, along with type of defect, location, duration of lesion, success or failure of OTSC, and nutritional status were compiled. The ACS NSQIP surgical risk calculator was used to project the risk of mortality, complications, length of stay, and risk of readmission had our patients undergone surgical correction of their fistula. RESULTS: Overall success for EC fistula closure was 70%. Acute fistulas were closed with a success rate of 86%. Chronic fistulas were closed successfully in only 33% of cases. Of patients successfully closed, NSQIP-predicted rates of mortality, any complication, and median length of stay were 21.1%, 34.5%, and 9.5 days, respectively. With OTSC, these patients experienced 0 mortalities, 0 complications, and had a median length of stay of 4 days. CONCLUSION: OTSC is an effective adjunctive measure to improving rates of successful closure of EC fistulas and compromised anastomosis. OTSC conveys a markedly improved procedural risk profile as compared to standard surgical correction.

Enterocutaneous Fistula Coexisting with Enterovesical Fistula: A Rare Complication of Ovarian Cystectomy.

Enterocutaneous fistula is an abnormal communication between the intestine and the skin, while enterovesical fistula is an abnormal communication between the intestine and the bladder. Both are not usual complications of ovarian cystectomy. We present a patient with enterovesical fistula coexisting with enterocutaneous fistula following ovarian cystectomy. She is a 24- year-old lady with background immunosupression who presented to the National Obstetric Fistula Centre, Abakaliki South-East Nigeria with a history fecaluria, pneumaturia and passage of feculent fluid through the skin following ovarian cystectomy. Fistulogram was in keeping with rectovesical fistula. She was repaired in a single stage and made an uneventful recovery. Enterovesical fistula and enterocutaneus fistula are uncommon but possible complications of ovarian cystectomy.

Considerations for the management of enterocutaneous fistula.

Enterocutaneous fistula is an abnormal connection between the gastrointestinal tract and skin. Management includes early recognition and treatment of sepsis, reducing fluid and electrolyte homeostasis, nutrition support, wound management and a carefully timed surgical procedure. A multidisciplinary approach is required for successful management of these patients with one of the most challenging and resource-demanding aspects being local control of the effluent, requiring the skill and support of the specialist stoma care nurse. The inability to contain the fistula can be a source of morbidity for the patient, as they will experience pain and severe discomfort from the skin when leakages occur. Enterocutaneous fistula can result in intestinal failure, which is often fatal if not managed correctly.

The Use of Latex Catheters to Close Enterocutaneous Fistulas: An Institutional Protocol and Retrospective Review.

OBJECTIVE: The objective of our study was to retrospectively review an institutional protocol that uses latex catheters for the treatment of enterocutaneous fistulas (ECFs) that are resistant to simple drainage. MATERIALS AND METHODS: Forty-six consecutive patients with ECFs that did not close with simple abscess drainage were treated with latex catheters. These patients' charts were retrospectively reviewed to determine treatment success rates and the relationship of treatment success to clinical characteristics. RESULTS: ECFs in 26 of the 46 (56.5%) patients were treated successfully with latex catheters. On univariate analysis, the fistulas that originated from the stomach were statistically less likely to close (p = 0.03), whereas those originating from the small bowel were more likely to close (p = 0.01). The duration of treatment was significantly longer in patients for whom the treatment failed than in those who were successfully treated (p = 0.003). After a total treatment time of more than 116 days (odds ratio [OR], 9.8 [95% CI, 2.5-38.4]; p = 0.001) or latex catheter treatment time of more than 74 days (OR, 8.9 [95% CI, 2.2-35.0]; p = 0.002), the chance of ECF closure decreased significantly. CONCLUSION: Treatment of ECFs that are resistant to simple abscess cavity drainage with a latex catheter is possible and decreases the need for surgery.

Complex abdominal wall reconstruction in the setting of active infection and contamination: a systematic review of hernia and fistula recurrence rates.

AIM: Minimal evidence exists to guide surgeons on the risk of complications when performing abdominal wall reconstruction (AWR) in the presence of active infection, contamination or enterocutaneous fistula. This study aims to establish the outcomes of contaminated complex AWR. METHOD: Analysis was conducted according to PRISMA guidelines. Systematic search of the MEDLINE, EMBASE and Pubmed databases was performed. Studies reporting exclusively on single-staged repair of contaminated complex AWR were included. Pooled data were analysed to establish rates of complications. RESULTS: Sixteen studies were included, consisting of 601 contaminated complex AWRs, of which 233 included concurrent enterocutaneous fistula repair. The average follow-up period was 26.7 months. There were 146 (24.3%) reported hernia recurrences. When stratified by repair method, suture repair alone had the lowest rate of recurrence (14.2%), followed by nonabsorbable synthetic mesh reinforcement (21.2%), biological mesh (25.8%) and absorbable synthetic mesh (53.1%). Hernia recurrence was higher when fascial closure was not achieved. Of the 233 enterocutaneous fistula repairs, fistula recurrence was seen in 24 patients (10.3%). Suture repair alone had the lowest rate of recurrence (1.6%), followed by nonbiological mesh (10.3%) and biological mesh reinforcement (12%). Forty-six per cent of patients were reported as having a wound-related complication and the mortality rate was 2.5%. CONCLUSION: It is feasible to perform simultaneous enterocutaneous fistula repair and AWR as rates of recurrent fistula are comparable with series describing enterocutaneous fistula repair alone. Hernias recurred in nearly a quarter of cases. This analysis is limited by a lack of comparative data and variability of outcome reporting.
