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.

Enterocutaneous Fistula and Abscess Diagnosed with Point-of-care Ultrasound

Case Presentation: A 64-year-old female with history of umbilical hernia repair with mesh 18 years prior, cystocele, and diabetes mellitus presented with 10 days of abdominal and flank pain. The patient was tachycardic, normotensive, afebrile, and had an erythematous, tender, protuberant abdominal wall mass. Point-of-care ultrasound (POCUS) revealed an irregular, heterogeneous extraperitoneal fluid collection with intraperitoneal communication; these findings were consistent with an abscess and infected mesh with evidence for intraperitoneal extension. The diagnosis of enterocutaneous fistula (ECF) with infected mesh and abdominal wall abscess was confirmed with computed tomography and the patient was admitted for antibiotics and source control. Discussion: A rare complication of hernia repair with mesh, ECF typically occurs later than more common complications including cellulitis, hernia recurrence, and bowel obstruction. In the emergency department, POCUS is commonly used to evaluate for abscess; in other settings, comprehensive ultrasound is used to evaluate for complications after hernia repair with mesh. However, to date there is no literature reporting POCUS diagnosis of ECF or mesh infection. This case suggests that distant surgery should not preclude consideration of mesh infection and ECF, and that POCUS may be useful in evaluating for these complications.

EP.FRI.616 Novel Technique of Gastrojejunostomy Tube Insertion to Control Retracted Proximal Stoma

Introduction Extensive small bowel resection for ischaemia can require formation of a proximal jejunostomy. Depending on length of remaining jejunum, a major potential complication is stoma retraction with resultant peritonitis, intra-abdominal sepsis and enterocutaneous fistula formation. We describe a case using a novel technique of inserting a retrograde gastrojejunostomy tube to gain control of an acutely retracted stoma in a 61 year old patient who developed an enterocutaneous fistula shortly after major resection due to ischaemia. Method Under fluoroscopic guidance, the retracted proximal limb of the jejunostomy was cannulated antegradely by guide wire. A gastro-jejunostomy tube was inserted retrograde over the guide wire and the tip placed within the stomach. The proximal tube fenestrations were sited within the duodenum and the balloon was inflated to limit enteric content spilling into the peritoneal cavity. Conclusion This technique enabled drainage of gastroduodenal fluid, minimised spillage into the peritoneal cavity, reduced fistula output and controlled sepsis. This allowed time for nutritional optimisation, better glycaemic control and endovascular revascularisation in preparation for restoration of intestinal continuity at an appropriate time. This method offered a useful alternative to surgery, in a patient for whom emergency re-exploration of the abdomen would carry significant risk of morbidity or mortality.

EP.FRI.337 Active management of the open abdomen in non-trauma catastrophes, including use of negative pressure wound therapy, is associated with high primary fascial closure rates

Aims Deliberate use of the open abdomen (OA) following emergency laparotomy (EL) may be life-saving in the non-trauma abdominal catastrophe (NTAC) and damage control surgery (DCS) can reduce the risk of abdominal compartment syndrome in compromised patients. Controversy exists over optimum management of the abdominal wall. An audit was undertaken of negative pressure wound therapy (NPWT) in OA patients. Methods All patients who underwent OA management of NTAC from 1st Jan 2019 to 31st Dec 2020 were identified. Data on patient demographics, indication for OA and clinical outcomes were analysed. Results Eighteen patients (median age 65.5 years; M:F9 each) underwent OA following EL. The indications were: bowel ischaemia (8), intra-abdominal sepsis (5), grossly distended bowel (3) and intra-abdominal haemorrhage (2). In all cases, ABTHERATM dressings (KCI/Acelity) were used. Mean ICU stay was 7.4 days (range 1-15) and mean hospital stay 33 days (range 2-61). Four patients died, 3 within 24 hours of initial EL. Relook laparotomy was performed within 48 hours in the remaining 15 patients; 3 patients required 2 relooks and 1 patient had three. Primary fascial closure (PFC) was achieved within five days in 13/14 (93%) survivors. Eight patients had SSIs with 2 intra-abdominal collections and all were treated conservatively. One patient developed an enterocutaneous fistula. Conclusions The use of commercially-available NPWT dressings in OA management is associated with high PFC rates within one week of initial EL. This practice is consistent with World Society of Emergency Surgery guidance recommending planned re-look laparotomy within 48 hours.

Comparison of Different Surgical Methods for Necrotizing Pancreatitis: A Meta-Analysis

Purpose: To compare the effectiveness and safety of three methods of open necrosectomy, minimally invasive surgery and endoscopic step-up approach for necrotizing pancreatitis.Methods: We searched Pubmed, Embase, ScienceDirect, and CNKI full text database (CNKI) (to December 25, 2019). RCT, prospective cohort study (PCS), and retrospective cohort study (RCS) comparing the effectiveness and safety of any two of above-mentioned three methods were included.Results: There was no significant difference in major complications or death, and mortality between the minimally invasive surgery treatment group and the endoscopic step-up approach treatment group (RR = 1.66, 95%CI: 0.83–3.33, P = 0.15; RR = 1.05, 95%CI: 0.59–1.86, P = 0.87); the incidence rate of new-onset multiple organ failure, enterocutaneous fistula, pancreatic-cutaneous fistula, intra-abdominal bleeding, and endocrine pancreatic insufficiency in the endoscopic step-up approach treatment group was significantly lower than minimally invasive surgery group (RR = 2.65, 95%CI: 1.10–6.36, P = 0.03; RR = 6.63, 95%CI: 1.59–27.60, P = 0.009; RR = 7.73, 95%CI: 3.00–19.89, P < 0.0001; RR = 1.91, 95%CI: 1.13–3.24, P = 0.02; RR = 1.83, 95%CI: 1.9–3.16, P = 0.02); hospital stay in the endoscopic step-up approach group was significantly shorter than minimally invasive surgical treatment group (MD = 11.26, 95%CI: 5.46–17.05, P = 0.0001). The incidence of pancreatic-cutaneous fistula in the endoscopic escalation step therapy group was significantly lower than that in the open necrosectomy group (RR = 0.11, 95%CI: 0.02–0.58, P = 0.009).Conclusion: Compared with minimally invasive surgery and open necrosectomy, although endoscopic step-up approach cannot reduce the main complications or death and mortality of patients, it can significantly reduce the incidence of some serious complications, such as pancreatic-cutaneous fistula, enterocutaneous fistula, intra-abdominal bleeding, endocrine pancreatic insufficiency, and can significantly shorten the patient's hospital stay.

1431 Stoma Intubation, Isolation and Negative Pressure Wound Therapy for Complex Stoma-Associated Wounds: New Technique and Case Series

Background The use of negative pressure wound therapy (NPWT) in colorectal surgery has been demonstrated for treating perineal defects, enterocutaneous fistula and stoma dehiscence. Here we describe a technique for closure of complex stoma-associated wounds using a novel commercial intubation device alongside NPWT to protect the surrounding wound from the stoma effluent. The device has previously described for use with enterocutaneous fistula. We present two cases that have been successfully treated with this technique. Technique and Cases The first case is of 88-year-old women with a retracted loop ileostomy and the second a 48 year-old male with a retracted end colostomy. Both patients underwent significant emergency peristomal debridement and in both cases the commercial device was deployed to intubate the stoma. VAC foam and standard adhesive dressings were used to form a quality seal and the pressure set to 125mmHg. In both cases near complete healing was achieved to the point that standard stoma bags and management could be used. Conclusions This is the first description of the use of an isolation device in complex stoma associated wounds. We have found the Fistula Funnel to be highly effective in this context.

867 A Novel Use for Silicone Expanders: Reducing Pelvic Dead Space and Preventing Bowel Herniation When Managing Radical Exenterative Surgery Complications

Aim To date, there is no clear consensus regarding the best way to obliterate the pelvic dead space, as seen in patients treated for recurrent perineal herniation and entero-cutaneous fistuli following total pelvic exenteration (TPE) for locally advanced rectal cancer. We present a novel technique using saline-filled breast expander to fill the dead space and create an artificial pelvic floor using the implant capsule, thus preventing intestinal herniation and fistuli formation in the multi-operated and irradiated pelvis scenario. Method We present 2 patients who initially had TPE, IGAP flap perineal reconstruction and neoadjuvant chemoradiotherapy. Patient 1 had 2 laparotomies for persistent enteroperineal fistulae in the 2-year postoperative period. Patient 2 had persistent wound discharge 2 years post TPE and underwent an enterocutaneous fistula repair and wound debridement. Both cases were complicated by perineal herniation and re-presented with persistent fistulation. A Becker 25 breast expander was placed into the pelvis and inflated with 150 ml of saline, to help contain the small bowel in the abdomen and reduce the risk of perineal re-herniation and fistulae. Results The silicone device was removed at 7-12 months, preserving its capsule, by the time the wound had healed. The wounds remained healed at post-operative follow up without any further perineal wound complications, herniation or fistuli Conclusions Addressing the dead pelvic space by using a breast expander may treat this particular TPE complication. The capsule created following placement of breast implant, facilitates artificial pelvic floor.
