Renoduodenal Fistula Following Penetrating Abdominal Injury

Renoduodenal fistula is an uncommon occurrence and usually results as a complication of injury or inflammatory process. Here, we describe a case of renoduodenal fistula formation after traumatic injury via gunshot wound to the abdomen. The patient suffered right renal and ureteral injury, complicated by urine leak, managed by surgery, interventional radiology, and urology. His post-hospital course was complicated by recurrent urinary tract infections and was found to have a renoduodenal fistula 3 months after the initial operation. Patient underwent uncomplicated right nephrectomy and repair of fistula. Etiology, presentation, diagnosis, and treatment options of renoduodenal fistula are discussed.

3 Damage control surgery in a regional trauma centre – defining the population: a pilot study

IntroductionTrauma has a major disease burden, by causing physiological disruption.1 Damage Control Surgery (DCS) minimises physiological disruption.2 3 The demographics of patients who undergo DCS surgery within our institution are unknown. This study aims to characterise our DCS cohort and potential for prospective study.MethodsOur hospital has a DCS protocol.4 This ensures the appropriate patients are safely and promptly transferred to a prepared operating theatre. All ORSOS data were captured from Nov 2017 – Sep 2019. Data was reviewed, and demographics analysed.ResultsThe DCS protocol was put on stand-by 42 times and activated in 21. Patient data was held for 38 cases, 30 male and 8 female, median age 37 years.Median Injury Severity Score was 29, with patients sustaining injuries from a range of mechanisms, figure 1. Median inpatient stay was 12 days, with a 29% 30-day mortality.Abstract 3 Figure 1Together this shows that despite prompt surgical intervention, a young patient cohort carries a significant mortality.ConclusionsWe have established the demographics of those who trigger DCS protocol use in a regional trauma centre. The resultant database enables prospective data collection for future DCS patients. Such data will afford our region a greater understanding of the DCS population.ReferencesPolinder S, Haagsma JA, Toet H, van Beeck EF.

Penetrating abdominal trauma – selected case reports

We present 3 case-reports with penetrating abdominal injury from our practice in this article. An urgent laparotomy was performed in all cases because of haemodynamic instability or the mechanism of injury. Penetrative abdominal traumas are associated with a high risk of life-threatening intra-abdominal injuries, require urgent revision and are often accompanied by postoperative infections of the peritoneal cavity. In recent years, there has been a growing tendency towards mini-invasive approaches or even non-operative treatment. This trend is particularly evident in the United States of America, where doctors experience a higher number of penetrating injuries compared to the prevalent blunt force trauma in Europe. The authors describe the need to follow all recommended procedures in the pre-hospital and hospital phases of treatment of these patients and compare them with recent literature.

Safety of Transrectal or Transvaginal Drainage of Pelvic Abscesses

Objective The literature on the safety and long-term sequelae of transrectal and transvaginal drainage of pelvic abscesses is limited. We evaluated the outcomes and safety of pelvic abscess drainage by interventional radiology at our institution. Methods After obtaining institutional review board approval, we retrospectively evaluated the outcomes of transrectal and transvaginal pelvic abscesses drainage using computed tomography, endorectal ultrasound, and or fluoroscopy. Results The study included 26 patients, with an age range of 24 to 88 years old, out of whom 53.8% were men. A total of 46.1% of the participants were African Americans and 26.9% were Caucasians. The average body mass index was 28.4 (range: 15.6 to 41.9). The most common etiology was penetrating abdominal injury (27%), followed by appendectomy (23%), diverticular disease (11.5%), anastomotic leak (11.5%), and disorders of gynecological causes (11.5%). The mean abscess diameter was 6.3 cm (range: 3.3 to 10.0 cm). Transrectal drainage was performed in all except one patient who had a transvaginal drainage. Transrectal ultrasound was used for drainage in 92.3% cases, and fluoroscopy was used as an additional imaging modality in 75% of the cases. An 8- or 10-Fr pigtail catheter was used in > 80% of the patients. Drains were removed between 2 and 7 days in 92.3% of the cases. The average follow-up was 30.4 months (range: 1 to 107 months), and no long-term complications were reported. Only one patient required subsequent operative intervention for an anastomotic leak. Conclusions Pelvic abscess drainage by transrectal route using radiological guidance is a safe and effective procedure.

Sodium Alginate as Treatment for Penetrating Abdominal Trauma- Feasibility Study.

Introduction: Penetrating abdominal injury is a major cause of death in trauma. It may cause hypovolemia leading to tissue hypoperfusion, direct organ damage and cytokine activation that cause inflammatory damage, all of which lead to death. Alginate is a natural anionic polysaccharide typically derived from brown algae. Sodium alginate hydrogel, a hemostatic agent, offers a platform for targeting both mechanical and biological injuries. The current study assessed the effect of a sodium alginate denoted VLVG (Very Low Viscosity (high) G alginate) following abdominal trauma in a swine model of penetrating abdominal injury. Methods: Seven anesthetized pigs were instrumented with catheters and abdominal trauma was introduced by laparoscopic hepatectomy. Ten minutes after the induction of hypovolemic shock, three animals were intra-abdominally administered with VLVG and four animals with saline (controls). During 8h of continuous monitoring, various hemodynamic and biochemical variables were measured and liver biopsies for histological evaluation were taken. In order to compare the study group to the control in a specific time a-parametric Mann-Whitney test was used, assessment of tendency during time Friedman's test for a-parametric variables was used. In order to compare the effect of the treatment (i.e. normal saline VS VLVG alginate) repeated measures ANOVA model was used, and the p value was calculated based on the Greenhouse-Geiser test. This research was approved by the Hebrew University of Jerusalem ethics Committee number: MD16148533. Results: VLVG-treated animals were more hemodynamically stable vs controls as reflected by their lower heart rate and higher blood pressure. They also had lower levels of liver enzymes and lactate and tissue damage. Conclusions: Our results in this pilot abdominal injury model show that VLVG might be a promising new agent. The superior hemostatic and biocompatibility efficiency along with its tissue preserving properties may turn VLVG in the future to a device that could be used in the pre-hospital setting to improve survival of abdominal trauma injuries.

Selective non-operative management for penetrating abdominal injury in a Dutch trauma centre

Introduction Selective non-operative management (SNOM) for penetrating abdominal injury (PAI) is accepted in trauma centres in South Africa and the US. Owing to the low incidence of gunshot wounds (GSWs) in Western Europe, few are inclined to practise SNOM for such injuries although it is considered for stab wounds (SWs). This study evaluated the outcome of patients admitted to a Dutch level 1 trauma centre with PAI. Methods A retrospective study was undertaken of all PAI patients treated over 15 years. In order to prevent bias, patients admitted six months prior to and six months following implementation of a treatment algorithm were excluded. Data concerning type of injury, injury severity score and treatment were compared. Results A total of 393 patients were included in the study: 278 (71%) with SWs and 115 (29%) with GSWs. Of the 178 SW patients in the SNOM group, 111 were treated before and 59 after introduction of the protocol. The SNOM success rates were 90% and 88% respectively (p=0.794). There were 43 patients with GSWs in the SNOM cohort. Of these, 32 were treated before and 11 after implementation of the algorithm, with respective success rates of 94% and 100% (p=0.304). The protocol did not bring about any significant change in the rate of non-therapeutic laparotomies for SWs or GSWs. However, the rate of admission for observation for SWs increased from 83% to 100% (p<0.001). There was a decrease in ultrasonography for SWs (from 84% to 32%, p<0.001) as well as for GSWs (from 87% to 43%, p<0.001). X-ray was also used less for GSWs after the protocol was introduced (44% vs 11%, p=0.001). Conclusions SNOM for PAI resulting from either SWs or GSWs can be safely practised in Western European trauma centres. Results are comparable with those in trauma centres that treat high volumes of PAI cases.
