Evaluating the effectiveness and outcomes associated with direct peritoneal resuscitation in damage control surgery patients with and without hemorrhagic shock. Injury 2024; 55:111361. [PMID: 38246013 DOI: 10.1016/j.injury.2024.111361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 01/15/2024] [Accepted: 01/15/2024] [Indexed: 01/23/2024]
Abstract
INTRODUCTION This narrative review aims to evaluate the efficacy of adjunct direct peritoneal resuscitation (DPR) in the treatment of adult damage control surgery (DCS) patients both with and without hemorrhagic shock, and its impact on associated outcomes. METHODS PubMed, Google Scholar, EMBASE, ProQuest, and Cochrane were searched for relevant articles published through April 13th, 2023. Studies assessing the utilization of DPR in adult DCS patients were included. Outcomes included time to abdominal closure, intra-abdominal complications, in-hospital mortality, and ICU length of stay (ICU LOS). RESULTS Five studies evaluating 437 patients were included. In patients with hemorrhagic shock, DPR was associated with reduced time to abdominal closure (DPR 4.1 days, control 5.9 days, p = 0.002), intra-abdominal complications including abscess formation (DPR 27 %, control 47 %, p = 0.04), and ICU LOS (DPR 8 days, control 11 days, p = 0.004). Findings in patients without hemorrhagic shock were conflicting. Closure times were decreased in one study (DPR 5.9 days, control 7.7 days, p < 0.02) and increased in another study (DPR 3.5 days, control 2.5 days, p = 0.02), intra-abdominal complications were decreased in one study (DPR 27 %, control 47 %, p = 0.04) and similar in another, and ICU LOS was decreased in one study (DPR 17 days, control 24 days, p < 0.002) and increased in another (DPR 13 days, control 11.4 days, p = 0.807). CONCLUSION In patients with hemorrhagic shock, adjunct DPR is associated with reduced time to abdominal closure, intra-abdominal complications such as abscesses, fistula, bleeding, anastomotic leak, and ICU LOS. Utilization of DPR in patients without hemorrhagic shock showed promising but inconsistent findings.

Entero-Cutaneous and Entero-Atmospheric Fistulas: Insights into Management Using Negative Pressure Wound Therapy. J Clin Med 2024; 13:1279. [PMID: 38592102 PMCID: PMC10932196 DOI: 10.3390/jcm13051279] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 02/14/2024] [Accepted: 02/22/2024] [Indexed: 04/10/2024] Open
Abstract
Enteric fistulas are a common problem in gastrointestinal tract surgery and remain associated with significant mortality rates, due to complications such as sepsis, malnutrition, and electrolyte imbalance. The increasingly widespread use of open abdomen techniques for the initial treatment of abdominal sepsis and trauma has led to the observation of so-called entero-atmospheric fistulas. Because of their clinical complexity, the proper management of enteric fistula requires a multidisciplinary team. The main goal of the treatment is the closure of enteric fistula, but also mortality reduction and improvement of patients' quality of life are fundamental. Successful management of patients with enteric fistula requires the establishment of controlled drainage, management of sepsis, prevention of fluid and electrolyte depletion, protection of the skin, and provision of adequate nutrition. Many of these fistulas will heal spontaneously within 4 to 6 weeks of conservative management. If closure is not accomplished after this time point, surgery is indicated. Despite advances in perioperative care and nutritional support, the mortality remains in the range of 15 to 30%. In more recent years, the use of negative pressure wound therapy for the resolution of enteric fistulas improved the outcomes, so patients can be successfully treated with a non-operative approach. In this review, our intent is to highlight the most important aspects of negative pressure wound therapy in the treatment of patients with enterocutaneous or entero-atmospheric fistulas.

The open abdomen in mesenteric ischemia: A tool for patients undergoing revascularization. World J Surg 2024; 48:331-340. [PMID: 38686782 DOI: 10.1002/wjs.12056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 12/09/2023] [Accepted: 12/13/2023] [Indexed: 05/02/2024]
Abstract
BACKGROUND We examined outcomes in Acute Mesenteric Ischemia (AMI) with the hypothesis that Open Abdomen (OA) is associated with decreased mortality. METHODS We performed a cohort study reviewing NSQIP emergency laparotomy patients, 2016-2020, with a postoperative diagnosis of mesenteric ischemia. OA was defined using flags for patients without fascial closure. Logistic regression was used with outcomes of 30-day mortality and several secondary outcomes. RESULTS Out of 5514 cases, 4624 (83.9%) underwent resection and 387 (7.0%) underwent revascularization. The OA rate was 32.6%. 10.8% of patients who were closed required reoperation. After adjustment for demographics, transfer status, comorbidities, preoperative variables including creatinine, white blood cell count, and anemia, as well as operative time, OA was associated with OR 1.58 for mortality (95% CI [1.38, 1.81], p < 0.001). Among revascularizations, there was no such association (p = 0.528). OA was associated with ventilator support >48 h (OR 4.04, 95% CI [3.55, 4.62], and p < 0.001). CONCLUSION OA in AMI was associated with increased mortality and prolonged ventilation. This is not so in revascularization patients, and 1 in 10 patients who underwent primary closure required reoperation. OA should be considered in specific cases of AMI.

Optimized Treatment of Nosocomial Peritonitis. Antibiotics (Basel) 2023; 12:1711. [PMID: 38136745 PMCID: PMC10740749 DOI: 10.3390/antibiotics12121711] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 11/24/2023] [Accepted: 12/01/2023] [Indexed: 12/24/2023] Open
Abstract
This comprehensive review aims to provide a practical guide for intensivists, focusing on enhancing patient care associated with nosocomial peritonitis (NP). It explores the epidemiology, diagnosis, and management of NP, a significant contributor to the mortality of surgical patients worldwide. NP is, per definition, a hospital-acquired condition and a consequence of gastrointestinal surgery or a complication of other diseases. NP, one of the most prevalent causes of sepsis in surgical Intensive Care Units (ICUs), is often associated with multi-drug resistant (MDR) bacteria and high mortality rates. Early clinical suspicion and the utilization of various diagnostic tools like biomarkers and imaging are of great importance. Microbiology is often complex, with antimicrobial resistance escalating in many parts of the world. Fungal peritonitis and its risk factors, diagnostic hurdles, and effective management approaches are particularly relevant in patients with NP. Contemporary antimicrobial strategies for treating NP are discussed, including drug resistance challenges and empirical antibiotic regimens. The importance of source control in intra-abdominal infection management, including surgical and non-surgical interventions, is also emphasized. A deeper exploration into the role of open abdomen treatment as a potential option for selected patients is proposed, indicating an area for further investigation. This review underscores the need for more research to advance the best treatment strategies for NP.

Abstract
PURPOSE OF REVIEW While the principles of damage control surgery - rapid hemorrhage and contamination control with correction of physiologic derangements followed by delayed definitive reconstruction - have remained consistent, forms of damage control intervention have evolved and proliferated dramatically. This review aims to provide a historic perspective of the early trends of damage control surgery as well as an updated understanding of its current state and future trends. RECENT FINDINGS Physiologically depleted patients in shock due to both traumatic and nontraumatic causes are often treated with damage control laparotomy and surgical principles. Damage control surgery has also been shown to be safe and effective in thoracic and orthopedic injuries. Damage control resuscitation is used in conjunction with surgical source control to restore patient physiology and prevent further collapse. The overuse of damage control laparotomy, however, is associated with increased morbidity and complications. With advancing technology, catheter- and stent-based endovascular modalities are playing a larger role in the resuscitation and definitive care of patients. SUMMARY Optimal outcome in the care of the most severely injured patients requires judicious use of damage control surgery supplemented by advancements in resuscitation and surgical adjuncts.

The impact of hypertonic saline on damage control laparotomy after penetrating abdominal trauma. Eur J Trauma Emerg Surg 2023:10.1007/s00068-023-02358-x. [PMID: 37773464 DOI: 10.1007/s00068-023-02358-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 08/21/2023] [Indexed: 10/01/2023]
Abstract
PURPOSE The inability to achieve primary fascial closure (PFC) after emergency laparotomy increases the rates of adverse outcomes including fistula formation, incisional hernia, and intraabdominal infection. Hypertonic saline (HTS) infusion improves early PFC rates and decreases time to PFC in patients undergoing damage control laparotomy (DCL) after injury. We hypothesized that in patients undergoing DCL after penetrating abdominal injury, HTS infusion would decrease the time to fascial closure as well as the volume of crystalloid required for resuscitation without inducing clinically relevant acute kidney injury (AKI) or electrolyte derangements. METHODS We retrospectively analyzed all penetrating abdominal injury patients undergoing DCL within the University of Pennsylvania Health System (January 2015-December 2018). We compared patients who received 3% HTS at 30 mL/h (HTS) to those receiving isotonic fluid (ISO) for resuscitation while the abdominal fascia remained open. Primary outcomes were the rate of early PFC (PFC within 72 h) and time to PFC; secondary outcomes included acute kidney injury, sodium derangement, ventilator-free days, hospital length of stay (LOS), and ICU LOS. Intergroup comparisons occurred by ANOVA and Tukey's comparison, and student's t, and Fischer's exact tests, as appropriate. A Shapiro-Wilk test was performed to determine normality of distribution. RESULTS Fifty-seven patients underwent DCL after penetrating abdominal injury (ISO n = 41, HTS n = 16). There were no significant intergroup differences in baseline characteristics or injury severity score. Mean time to fascial closure was significantly shorter in HTS (36.37 h ± 14.21 vs 59.05 h ± 50.75, p = 0.02), and the PFC rate was significantly higher in HTS (100% vs 73%, p = 0.01). Mean 24-h fluid and 48-h fluid totals were significantly less in HTS versus ISO (24 h: 5.2L ± 1.7 vs 8.6L ± 2.2, p = 0.01; 48 h: 1.3L ± 1.1 vs 2.6L ± 2.2, p = 0.008). During the first 72 h, peak sodium (Na) concentration (146.2 mEq/L ± 2.94 vs 142.8 mEq/L ± 3.67, p = 0.0017) as well as change in Na from ICU admission (5.1 mEq/L vs 2.3, p = 0.016) were significantly higher in HTS compared to ISO. Patients in the HTS group received significantly more blood in the trauma bay compared to ISO. There were no intergroup differences in intraoperative blood transfusion volume, AKI incidence, change in chloride concentration (△Cl) from ICU admit, Na to Cl gradient (Na:Cl), initial serum creatinine (Cr), peak post-operative Cr, change in creatinine concentration (△Cr) from ICU admission, creatinine clearance (CrCl), initial serum potassium (K), peak ICU K, change in K from ICU admission, initial pH, highest or lowest post-operative pH, mean hospital LOS, ICU LOS, and ventilator-free days. CONCLUSIONS HTS infusion in patients undergoing DCL after penetrating abdominal injury decreases the time to fascial closure and led to 100% early PFC. HTS infusion also decreased resuscitative fluid volume without causing significant AKI or electrolyte derangement. HTS appears to offer a safe and effective fluid management approach in patients who sustain penetrating abdominal injury and DCL to support early PFC without inducing measurable harm.

Primary anastomosis and suturing combined with vacuum-assisted abdominal closure in patients with secondary peritonitis due to perforation of the small intestine: a retrospective study. BMC Surg 2023; 23:280. [PMID: 37715227 PMCID: PMC10503050 DOI: 10.1186/s12893-023-02179-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Accepted: 08/31/2023] [Indexed: 09/17/2023] Open
Abstract
BACKGROUND Intestinal resection and a proximal stoma is the preferred surgical approach in patients with severe secondary peritonitis due to perforation of the small intestine. However, proximal stomas may result in significant nutritional problems and long-term parenteral nutrition. This study aimed to assess whether primary anastomosis or suturing of small intestine perforation is feasible and safe using the open abdomen principle with vacuum-assisted abdominal closure (VAC). METHODS Between January 2005 and June 2018, we performed a retrospective chart review of 20 patients (> 18 years) with diffuse faecal peritonitis caused by small intestinal perforation and treated with primary anastomosis/suturing and subsequent open abdomen with VAC. RESULTS The median age was 65 years (range: 23-90 years). Twelve patients were female (60%). Simple suturing of the small intestinal perforation was performed in three cases and intestinal resection with primary anastomosis in 17 cases. Four patients (20%) died within 90-days postoperatively. Leakage occurred in five cases (25%), and three patients developed an enteroatmospheric fistula (15%). Thirteen of 16 patients (83%) who survived were discharged without a stoma. The rest had a permanent stoma. CONCLUSIONS Primary suturing or resection with anastomosis and open abdomen with VAC in small intestinal perforation with severe faecal peritonitis is associated with a high rate of leakage and enteroatmospheric fistula formation. TRIAL REGISTRATION The study was approved by the Danish Patient Safety Authority (case number 3-3013-1555/1) and the Danish Data Protection Agency (file number 18/28,404). No funding was received.

Baricitinib protects mice from sepsis-induced cardiac dysfunction and multiple-organ failure. Front Immunol 2023; 14:1223014. [PMID: 37781388 PMCID: PMC10536262 DOI: 10.3389/fimmu.2023.1223014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 08/07/2023] [Indexed: 10/03/2023] Open
Abstract
Sepsis is one of the major complications of surgery resulting in high morbidity and mortality, but there are no specific therapies for sepsis-induced organ dysfunction. Data obtained under Gene Expression Omnibus accession GSE131761 were re-analyzed and showed an increased gene expression of Janus Kinase 2 (JAK2) and Signal Transducer and Activator of Transcription 3 (STAT3) in the whole blood of post-operative septic patients. Based on these results, we hypothesized that JAK/STAT activation may contribute to the pathophysiology of septic shock and, hence, investigated the effects of baricitinib (JAK1/JAK2 inhibitor) on sepsis-induced cardiac dysfunction and multiple-organ failure (MOF). In a mouse model of post-trauma sepsis induced by midline laparotomy and cecal ligation and puncture (CLP), 10-week-old male (n=32) and female (n=32) C57BL/6 mice received baricitinib (1mg/kg; i.p.) or vehicle at 1h or 3h post-surgery. Cardiac function was assessed at 24h post-CLP by echocardiography in vivo, and the degree of MOF was analyzed by determination of biomarkers in the serum. The potential mechanism underlying both the cardiac dysfunction and the effect of baricitinib was analyzed by western blot analysis in the heart. Trauma and subsequent sepsis significantly depressed the cardiac function and induced multiple-organ failure, associated with an increase in the activation of JAK2/STAT3, NLRP3 inflammasome and NF- κβ pathways in the heart of both male and female animals. These pathways were inhibited by the administration of baricitinib post the onset of sepsis. Moreover, treatment with baricitinib at 1h or 3h post-CLP protected mice from sepsis-induced cardiac injury and multiple-organ failure. Thus, baricitinib may be repurposed for trauma-associated sepsis.

The open abdomen in trauma, acute care, and vascular and endovascular surgery: comprehensive, expert, narrative review. BJS Open 2023; 7:zrad084.

Abstract
BACKGROUND The open abdomen is an innovation that greatly improved surgical understanding of damage control, temporary abdominal closure, staged abdominal reconstruction, viscera and enteric fistula care, and abdominal wall reconstruction. This article provides an evidence-informed, expert, comprehensive narrative review of the open abdomen in trauma, acute care, and vascular and endovascular surgery. METHODS A group of 12 international trauma, acute care, and vascular and endovascular surgery experts were invited to review current literature and important concepts surrounding the open abdomen. RESULTS The open abdomen may be classified using validated systems developed by a working group in 2009 and modified by the World Society of the Abdominal Compartment Syndrome-The Abdominal Compartment Society in 2013. It may be indicated in major trauma, intra-abdominal sepsis, vascular surgical emergencies, and severe acute pancreatitis; to facilitate second look laparotomy or avoid or treat abdominal compartment syndrome; and when the abdominal wall cannot be safely closed. Temporary abdominal closure and staged abdominal reconstruction methods include a mesh/sheet, transabdominal wall dynamic fascial traction, negative pressure wound therapy, and hybrid negative pressure wound therapy and dynamic fascial traction. This last method likely has the highest primary fascial closure rates. Direct peritoneal resuscitation is currently an experimental strategy developed to improve primary fascial closure rates and reduce complications in those with an open abdomen. Primary fascial closure rates may be improved by early return to the operating room; limiting use of crystalloid fluids during the surgical interval; and preventing and/or treating intra-abdominal hypertension, enteric fistulae, and intra-abdominal collections after surgery. The majority of failures of primary fascial closure and enteroatmospheric fistula formation may be prevented using effective temporary abdominal closure techniques, providing appropriate resuscitation fluids and nutritional support, and closing the abdomen as early as possible. CONCLUSION Subsequent stages of the innovation of the open abdomen will likely involve the design and conduct of prospective studies to evaluate appropriate indications for its use and effectiveness and safety of the above components of open abdomen management.

Abstract
INTRODUCTION Up to the present time, the laparoscopic approach for colon cancer is considered the gold standard. However, robotic surgery has been appraised in modern medicine. It is essential to evaluate the differences between laparoscopic and robotic surgery, owing to the significant impact they cause in postoperative morbidity and mortality. This article aims to perform a systematic review and meta-analysis of the literature to compare robotic versus laparoscopic colectomies in patients with colon cancer in terms of the incidence of colonic fistulas. METHODS AND ANALYSIS PubMed, Embase, Scopus, Web of Science, Science Direct, Cochrane Central Register of Controlled Trials, CINAHL, LILACS and Clinical trials databases will be searched for randomised clinical trials investigating the incidence of colonic fistulas in patients with colonic cancer, submitted to robotic surgery compared with a laparoscopic approach. No language or publication period restrictions will be imposed. The primary outcome will be the incidence of colonic fistulas in patients with colon cancer in different surgical approaches. The secondary outcomes will be the incidence of infection, sepsis, mortality, length of hospitalisation and malnutrition. Three independent reviewers will select the studies and extract data from the original publications. The risk of bias will be assessed using The Risk of Bias 2 tool, and the evidence's certainty will be made using the Grading of Recommendations Assessment, Development and Evaluation. Data synthesis will be performed using the Review Manager software (RevMan V.5.2.3). To assess heterogeneity. We will compute the I2 statistics. In addition, a quantitative synthesis will be performed if the included studies are sufficiently homogeneous. ETHICS AND DISSEMINATION This study will review the published data; thus, it is not necessary to obtain ethical approval. The findings of this systematic review will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42021295313.

The variable role of damage control laparotomy over 19 years of trauma care in Pennsylvania. Surgery 2022; 173:1289-1295.

Abstract
BACKGROUND Damage control laparotomy emphasizes physiologic stabilization of critically injured patients and allows staged surgical management. However, there is little consensus on the optimal criteria for damage control laparotomy. We examined variability between centers and over time in Pennsylvania. METHODS We analyzed the Pennsylvania Trauma Outcomes Study data between 2000 and 2018, excluding centers performing <10 laparotomies/year. Laparotomy was defined using International Classification of Diseases codes, and damage control laparotomy was defined by a code for "reopening of recent laparotomy" or a return to the operating room >4 hours from index laparotomy that was not unplanned. We examined trends over time and by center. Multivariable logistic regression models were developed to predict both damage control laparotomy and mortality, generate observed:expected ratios, and identify outliers for each. We compared risk-adjusted mortality rates to center-level damage control laparotomy rates. RESULTS In total, 18,896 laparotomies from 22 centers were analyzed; 3,549 damage control laparotomies were performed (18.8% of all laparotomies). The use of damage control laparotomy in Pennsylvania varied from 13.9% to 22.8% over time. There was wide variation in center-level use of damage control laparotomy, from 11.1% to 29.4%, despite adjustment. Factors associated with damage control laparotomy included injury severity and admission vital signs. Center identity improved the model as demonstrated by likelihood ratio test (P < .001), suggesting differences in center-level practices. There was minimal correlation between center-level damage control laparotomy use and mortality. CONCLUSION There is wide center-level variation in the use of damage control laparotomy among centers, despite adjustment for patient factors. Damage control laparotomy is both resource intensive and highly morbid; regional resources should be allocated to address this substantial practice variation to optimize damage control laparotomy use.

Abstract
BACKGROUND Initially used in trauma management, delayed abdominal closure endeavors to decrease operative time during the index operation while still being lifesaving. Its use in emergency general surgery is increasing, but the data evaluating its outcome are sparse. We aimed to study the association between delayed abdominal closure, mortality, morbidity, and length of stay in an emergency surgery cohort. METHODS The 2013 to 2017 American College of Surgeons National Surgical Quality Improvement Program database was examined for patients undergoing emergency laparotomy. The patients were classified by the timing of abdominal wall closure: delayed fascial closure versus immediate fascial closure. Propensity score matching was performed based on preoperative covariates, wound classification, and performance of bowel resection. The outcomes were then compared by univariable analysis. RESULTS After matching, both the delayed fascial closure and immediate fascial closure groups consisted of 3,354 patients each. Median age was 65 years, and 52.6% were female. The delayed fascial closure group had a higher in-hospital mortality (35.3% vs 25.0%, P < .001), a higher 30-day mortality (38.6% vs 29.0%, P < .001), a higher proportion of acute kidney injury (9.5% vs 6.6%, P < .001), a lower proportion of postoperative sepsis (11.8% vs 15.6%, P < .001), and a lower proportion of surgical site infection (3.4% vs 7.0%, P < .001). CONCLUSION Compared with immediate fascial closure, delayed fascial closure is associated with an increased mortality in the patients matched based on comorbidities and surgical site contamination. In emergency general surgery, delaying abdominal closure may not have the presumed overarching benefits, and its indications must be further defined in this population.

Abstract
Direct peritoneal resuscitation (DPR) has been found to be a useful adjunct in the management of critically ill trauma patients. DPR is performed following damage control surgery by leaving a surgical drain in the mesentery, placing a temporary abdominal closure, and postoperatively running peritoneal dialysis solution through the surgical drain with removal through the temporary closure. In the original animal models, the peritoneal dialysate infusion was found to augment visceral microcirculatory blood flow reducing the ischemic insult that occurs following hemorrhagic shock. DPR was also found to minimize the aberrant immune response that occurs secondary to shock and contributes to multisystem organ dysfunction. In the subsequent human trials, performing DPR had significant effects in several key categories. Traumatically injured patients who received DPR had a significantly shorter time to definitive fascial closure, had a higher likelihood of achieving primary fascial closure, and experienced fewer abdominal complications. The use of DPR has been further expanded as a useful adjunct for emergency general surgery patients and in the pretransplant care of human cadaver organ donors.

Abstract
BACKGROUND Enteroatmospheric fistula (EAF) is a catastrophic complication that can occur after open abdomen. EAFs cause severe body fluid loss, hypercatabolism, and wound complications, leading to adverse clinical outcomes.
CASE SUMMARY A 72-year-old female patient underwent ventral hernia repair. Five days after the surgery, she exhibited severe abdominal pain with septic shock. Exploratory laparotomy revealed extensive intestinal adhesions and severe intraperitoneal contamination. Since the patient was hemodynamically unstable, a salvage operation rather than definite surgery was needed, and three surgical open drains were inserted into the peritoneal cavity. Postoperative EAFs developed, and it was almost impossible to isolate and reduce the fistula output despite the use of vacuum-assisted closure dressings and endoscopic stent insertion. Finally, we anastomosed two vascular grafts to the openings of each EAF to restore enteric continuity. The inserted vascular grafts showed acceptable patency, and the patient could receive optimal nutritional support with elemental enteral feeding. She underwent EAF resection 76 d after graft implantation.
CONCLUSION Control of the enteric effluent are key elements in achieving favorable clinical conditions which should precede definite surgery for EAFs.

Vacuum-assisted closure versus on-demand relaparotomy in patients with secondary peritonitis-the VACOR trial: protocol for a randomised controlled trial. World J Emerg Surg 2022; 17:25. [PMID: 35619144 PMCID: PMC9137120 DOI: 10.1186/s13017-022-00427-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 05/11/2022] [Indexed: 11/25/2022] Open
Abstract
Background Secondary peritonitis is a severe condition with a 20–32% reported mortality. The accepted treatment modalities are vacuum-assisted closure (VAC) or primary closure with relaparotomy on-demand (ROD). However, no randomised controlled trial has been completed to compare the two methods potential benefits and disadvantages. Methods This study will be a randomised controlled multicentre trial, including patients aged 18 years or older with purulent or faecal peritonitis confined to at least two of the four abdominal quadrants originating from the small intestine, colon, or rectum. Randomisation will be web-based to either primary closure with ROD or VAC in blocks of 2, 4, and 6. The primary endpoint is peritonitis-related complications within 30 or 90 days and one year after index operation. Secondary outcomes are comprehensive complication index (CCI) and mortality after 30 or 90 days and one year; quality of life assessment by (SF-36) after three and 12 months, the development of incisional hernia after 12 months assessed by clinical examination and CT-scanning and healthcare resource utilisation. With an estimated superiority of 15% in the primary outcome for VAC, 340 patients must be included. Hospitals in Denmark and Europe will be invited to participate. Discussion There is no robust evidence for choosing either open abdomen with VAC treatment or primary closure with relaparotomy on-demand in patients with secondary peritonitis. The present study has the potential to answer this important clinical question. Trial Registration The study protocol has been registered at clinicaltrials.gov (NCT03932461). Protocol version 1.0, 9 January 2022. Supplementary Information The online version contains supplementary material available at 10.1186/s13017-022-00427-x.

Development and validation of a multivariable prediction model in open abdomen patients for entero-atmospheric fistula. ANZ J Surg 2022; 92:1079-1084. [PMID: 35119771 PMCID: PMC9303347 DOI: 10.1111/ans.17512] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 01/12/2022] [Accepted: 01/15/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Laparostomy or Open Abdomen (OA) has matured into an effective strategy in the management of abdominal catastrophe. Single prognostic factors have been identified in a previous systematic review regarding entero-atmospheric fistula (EAF). Unfortunately, no prognostic multivariable model for EAF exist. The aim was to develop and validate a multivariable prediction model from a retrospective cohort study involving three hospital's databases. METHODS Fifty-seven variables were evaluated to develop a multivariable model. Univariate and multivariable logistic regression analyses were performed for on a developmental data set from two hospitals. Receiver operator characteristics analysis with area under the curve (AUC) and 95% confidence intervals (CI) were performed on the developmental data set (internal validation) as well as on an additional validation data set from another hospital (external validation). RESULTS Five-hundred and forty-eight patients managed with an OA. Two variables remained in the multivariable prediction model for EAF. The AUC for EAF on internal validation were 0.74 (95% CI: 0.58-0.86) and 0.79 (95% CI: 0.67-0.92) on external validation. CONCLUSIONS A multivariable prediction model for EAF was externally validated and an easy-to-use probability nomogram was constructed using the two predictor variables. LEVEL OF EVIDENCE III; prognostic.

Abstract
PURPOSE Damage control laparotomy (DCL) is used for both traumatic and non-traumatic indications. Failure to achieve primary fascial closure (PFC) in a timely fashion has been associated with complications including sepsis, fistula, and mortality. We sought to identify factors associated with time to PFC in a multicenter retrospective cohort. METHODS We reviewed retrospective data from 15 centers in the EAST SLEEP-TIME registry, including age, comorbidities (Charlson Comorbidity Index [CCI]), small and large bowel resection, bowel discontinuity, vascular procedures, retained packs, number of re-laparotomies, net fluid balance after 24 h, trauma, and time to first takeback in 12-h increments to identify key factors associated with time to PFC. RESULTS In total, 368 patients (71.2% trauma, of which 50.6% were penetrating, median ISS 25 [16, 34], with median Apache II score 15 [11, 22] in non-trauma) were in the cohort. Of these, 92.9% of patients achieved PFC at 60.8 ± 72.0 h after 1.6 ± 1.2 re-laparotomies. Each additional re-laparotomy reduced the odds of PFC by 91.5% (95%CI 88.2-93.9%, p < 0.001). Time to first re-laparotomy was highly significant (p < 0.001) in terms of odds of achieving PFC, with no difference between 12 and 24 h to first re-laparotomy (ref), and decreases in odds of PFC of 78.4% (65.8-86.4%, p < 0.001) for first re-laparotomy after 24.1-36 h, 90.8% (84.7-94.4%, p < 0.001) for 36.1-48 h, and 98.1% (96.4-99.0%, p < 0.001) for > 48 h. Trauma patients had increased likelihood of PFC in two separate analyses (p = 0.022 and 0.002). CONCLUSION Time to re-laparotomy ≤ 24 h and minimizing number of re-laparotomies are highly predictive of rapid achievement of PFC in patients after trauma- and non-trauma DCL. LEVEL OF EVIDENCE 2B.

Abstract
Vascular Ehlers-Danlos syndrome is a rare connective tissue disease with a high risk of severe complications. Because of these complications, the median life expectancy for patients with vascular Ehlers-Danlos syndrome is estimated at 48 years. However, the optimal management of these complications remains unclear. A 25-year-old man with abdominal pain was transported to our hospital by ambulance. He had undergone Hartmann's operation at 22 years of age for a first-time colonic perforation. At that time, a genetic test revealed germline variants in COL3A1, which encodes type III procollagen; therefore, the patient was diagnosed with vascular Ehlers-Danlos syndrome. When the patient presented to our hospital, we suspected another colonic perforation and thus performed an emergency operation. Open abdominal management, transcatheter arterial embolization, and negative-pressure wound therapy were performed as life-saving measures. Notably, these procedures should initially be avoided in patients with vascular Ehlers-Danlos syndrome because of tissue fragility. Open abdominal management, transcatheter arterial embolization, and negative-pressure wound therapy may be useful for patients with vascular Ehlers-Danlos syndrome who develop panperitonitis and massive intra-abdominal bleeding.

Abstract
We present the case of a 23-year-old man who developed abdominal compartment syndrome secondary to severe pancreatitis and required decompressive laparotomy and pancreatic necrosectomy. Despite application of a temporary abdominal closure system (ABThera Open Abdomen Negative Pressure Therapy), extensive retroperitoneal oedema and inflammation continued to contribute to loss of domain and prevented primary closure of the skin and fascia. The usual course of action would have involved reapplication of ABThera system until primary closure could be achieved or sufficient granulation tissue permitted split-thickness skin grafting. Though a safe option for abdominal closure, application of a skin graft would delay return to baseline functional status and require eventual graft excision with abdominal wall reconstruction for this active labourer. Thus, we achieved primary closure of the skin through the novel application of abdominal wall 'pie-crusting', or tension-releasing multiple skin incisions, technique.

Abstract
BACKGROUND Surgical site infections (SSIs) are well-recognized complications after exploratory laparotomy for abdominal trauma; however, little is known about SSI development after exploration for battlefield abdominal trauma. We examined SSI risk factors after exploratory laparotomy among combat casualties. METHODS Military personnel with combat injuries sustained in Iraq and Afghanistan (June 2009 to May 2014) who underwent laparotomy and were evacuated to participating US military hospitals were included. Log-binominal regression was used to identify SSI risk factors. RESULTS Of 4,304 combat casualties, 341 patients underwent a total of 1,053 laparotomies. Abdominal SSIs were diagnosed in 49 patients (14.4%): 8% with organ space SSI, 4% with deep incisional SSI, and 4% with superficial SSIs (4 patients had multiple SSIs). Patients with SSIs had more colorectal (p < 0.001), small bowel (p = 0.010), duodenum (p = 0.006), pancreas (p = 0.032), and abdominal vascular injuries (p = 0.040), as well as prolonged open abdomen (p = 0.004) and more infections diagnosed before the SSI (or final exploratory laparotomy) versus non-SSI patients (p < 0.001). Sustaining colorectal injuries (risk ratio [RR], 3.20; 95% confidence interval [CI], 1.58-6.45), duodenum injuries (RR, 6.71; 95% CI, 1.73-25.58), and being diagnosed with prior infections (RR, 10.34; 95% CI, 5.05-21.10) were independently associated with any SSI development. For either organ space or deep incisional SSIs, non-intra-abdominal infections, fecal diversion, and duodenum injuries were independently associated, while being injured via an improvised explosive device was associated with reduced likelihood compared with penetrating nonblast (e.g., gunshot wounds) injuries. Non-intra-abdominal infections and hypotension were independently associated with organ space SSIs development alone, while sustaining blast injuries were associated with reduced likelihood. CONCLUSION Despite severity of injuries and the battlefield environment, the combat casualty laparotomy SSI rate is relatively low at 14%, with similar risk factors and rates reported following severe civilian trauma.

Abstract
BACKGROUND Damage-control laparotomy (DCL) has been used for traumatic and nontraumatic indications. We studied factors associated with delirium and outcome in this population. METHODS We reviewed DCL patients at 15 centers for 2 years, including demographics, Charlson Comorbidity Index (CCI), diagnosis, operations, and outcomes. We compared 30-day mortality; renal failure requiring dialysis; number of takebacks; hospital, ventilator, and intensive care unit (ICU) days; and delirium-free and coma-free proportion of the first 30 ICU days (DF/CF-ICU-30) between trauma (T) and nontrauma (NT) patients. We performed linear regression for DF/CF-ICU-30, including age, sex, CCI, achievement of primary fascial closure (PFC), small and large bowel resection, bowel discontinuity, abdominal vascular procedures, and trauma as covariates. We performed one-way analysis of variance for DF/CF-ICU-30 against traumatic brain injury severity as measured by Abbreviated Injury Scale for the head. RESULTS Among 554 DCL patients (25.8% NT), NT patients were older (58.9 ± 15.8 vs. 39.7 ± 17.0 years, p < 0.001), more female (45.5% vs. 22.1%, p < 0.001), and had higher CCI (4.7 ± 3.3 vs. 1.1 ± 2.2, p < 0.001). The number of takebacks (1.7 ± 2.6 vs. 1.5 ± 1.2), time to first takeback (32.0 hours), duration of bowel discontinuity (47.0 hours), and time to PFC were similar (63.2 hours, achieved in 73.5%). Nontrauma and T patients had similar ventilator, ICU, and hospital days and mortality (31.0% NT, 29.8% T). Nontrauma patients had higher rates of renal failure requiring dialysis (36.6% vs. 14.1%, p < 0.001) and postoperative abdominal sepsis (40.1% vs. 17.1%, p < 0.001). Trauma and NT patients had similar number of hours of sedative (89.9 vs. 65.5 hours, p = 0.064) and opioid infusions (106.9 vs. 96.7 hours, p = 0.514), but T had lower DF/CF-ICU-30 (51.1% vs. 73.7%, p = 0.029), indicating more delirium. Linear regression analysis indicated that T was associated with a 32.1% decrease (95% CI, 14.6%-49.5%; p < 0.001) in DF/CF-ICU-30, while achieving PFC was associated with a 25.1% increase (95% CI, 10.2%-40.1%; p = 0.001) in DF/CFICU-30. Increasing Abbreviated Injury Scale for the head was associated with decreased DF/CF-ICU-30 by analysis of variance (p < 0.001). CONCLUSION Nontrauma patients had higher incidence of postoperative abdominal sepsis and need for dialysis, while T was independently associated with increased delirium, perhaps because of traumatic brain injury.

Abstract
Background Damage control laparotomy (DCL) is a life-saving procedure in patients with abdominal hemorrhage. After DCL, patients are sometimes left with an open abdomen (OA) so they may undergo multiple exploratory laparotomies (EXLAP), or re-explorations. Patients with OA are at increased risk of infectious complications (ICs). The association between number of re-explorations after DCL and the number of ICs is not clear. We hypothesized that each additional re-exploration increases the risk of developing IC. Methods This 6-year retrospective cohort study included patients aged ≥16 years from the NTDB who had DCL defined as EXLAP within 2 hours of arrival (ICD-9: 54.11, 54.12, 54.19) with at least one re-exploration. The primary outcome was IC (ie, superficial surgical site infection (SSI), organ space SSI, deep SSI, sepsis, pneumonia, or catheter-related bloodstream infection), examined dichotomously (present/absent) and ordinally as the number of ICs. Multivariate Poisson regression was used to assess the association between number of re-explorations and number of ICs. Significance was assigned at p<0.01. Results There were 7431 patients who underwent DCL; 2509 (34%) patients developed at least one IC. The rate of IC was lowest in patients who were closed during the first re-exploration (27%) and significantly increased with each re-exploration to 59% in patients who had five or more re-explorations (Cochran-Armitage trend p<0.001). After adjustment, there was 14% increased risk of an additional IC with each re-exploration (p<0.001). Discussion For patients requiring DCL, each re-exploration of the abdomen is associated with increased rate of ICs. Level of evidence III, retrospective epidemiological study.

Abstract
BACKGROUND Fluid overload (FO) after resuscitation is frequent and contributes to adverse outcomes among postinjury open abdomen (OA) patients. Bioelectrical impedance analysis (BIA) is a promising tool for monitoring fluid status and FO. Therefore, we sought to investigate the efficacy of BIA-directed fluid resuscitation among OA patients. METHODS A pragmatic, prospective, randomized, observer-blind, single-center trial was performed for all trauma patients requiring OA between January 2013 and December 2017 to a national referral center. A total of 140 postinjury OA patients were randomly assigned in a 1:1 ratio to receive either a BIA-directed fluid resuscitation (BIA) protocol that included fluid administration with monitoring of hemodynamic parameters and different degrees of interventions to achieve a negative fluid balance targeting the hydration level (HL) measured by BIA or a traditional fluid resuscitation (TRD) in which clinicians determined the fluid resuscitation regimen according to traditional parameters during 30 days of ICU management. The primary outcome was the 30-day primary fascial closure (PFC) rate. The secondary outcomes included the time to PFC, postoperative 7-day cumulative fluid balance (CFB) and adverse events within 30 days after OA. The Kaplan-Meier method and the log-rank test were utilized for PFC after OA. A generalized linear regression model for the time to PFC and CFB was built. RESULTS A total of 134 patients completed the trial (BIA, n = 66; TRD, n = 68). The BIA patients were significantly more likely to achieve PFC than the TRD patients (83.33% vs. 55.88%, P < 0.001). In the BIA group, the time to PFC occurred earlier than that of the TRD group by an average of 3.66 days (P < 0.001). Additionally, the BIA group showed a lower postoperative 7-day CFB by an average of 6632.80 ml (P < 0.001) and fewer complications. CONCLUSION Among postinjury OA patients in the ICU, the use of BIA-guided fluid resuscitation resulted in a higher PFC rate and fewer severe complications than the traditional fluid resuscitation strategy.

Abstract
Introducción. Los pacientes que sufren algún tipo de trauma tienen una presentación clínica muy variable, por lo que se han diseñado pautas diagnósticas y terapéuticas con el fin de disminuir el número de laparotomías innecesarias. Las herramientas actuales para la predicción de infección intraabdominal, permiten intervenciones tempranas en los pacientes con alto riesgo y un mejor seguimiento clínico posoperatorio. El objetivo de este trabajo fue realizar un estudio de los factores asociados al desarrollo de las infecciones intraabdominales o sepsis abdominal posterior a laparotomía por trauma penetrante.
Métodos. Estudio descriptivo de una cohorte de pacientes atendidos por trauma abdominal penetrante en el Hospital Universitario de Santander, Bucaramanga, Colombia, entre enero de 2016 y diciembre de 2018. El análisis de datos se realizó en el software Stata®, versión 14 (StataCorp. LP, College Station, TX, USA).
Resultados. Se incluyeron 174 pacientes con edad media de 32 años, el 10,9 % (n=19) de los pacientes presentaron sepsis abdominal, de este grupo el 94,7 % (n=18) requirieron reintervención quirúrgica (p < 0,0001). La mortalidad general del grupo fue de 5,1 % (n=9), sin diferencia significativa entre los pacientes con o sin sepsis abdominal.
Discusión. Dentro de los diferentes desenlaces asociados a laparotomía por trauma, se describe la sepsis abdominal como una de las complicaciones que genera morbilidad significativa, con aumento en la estancia hospitalaria, necesidad de reintervención, aumento en los costos de atención y disminución en la calidad de vida, factores en concordancia con los hallazgos del presente estudio.

Abstract
The open abdomen (OA) is an established concept for treating severe abdominal diseases. The most frequent reasons for placement of an open abdomen are abdominal sepsis (e.g. from intestinal perforation or anastomotic leakage), severe abdominal organ injury and abdominal compartment syndrome. The pathophysiology is much more complex than the surgeon's eye can see in an OA. The temporary closure of the abdominal wall ensures sufficient drainage of infected ascites, protection of the intestinal loops and conditioning of the abdominal wall in order to be able carry out definitive closure of the abdominal wall at the end of the surgical treatment. Negative peritoneal pressure therapy combined with fascia traction (with or without mesh) is well-established in the management of an open abdomen.

Abstract
AIM There is a requirement for an expansive and up to date review of the management of emergency colorectal conditions seen in adults. The primary objective is to provide detailed evidence-based guidelines for the target audience of general and colorectal surgeons who are responsible for an adult population and who practise in Great Britain and Ireland. METHODS Surgeons who are elected members of the Association of Coloproctology of Great Britain and Ireland Emergency Surgery Subcommittee were invited to contribute various sections to the guidelines. They were directed to produce a pathology-based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. Each author was asked to provide a set of recommendations which were evidence-based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after two votes were included in the guidelines. RESULTS All aspects of care (excluding abdominal trauma) for emergency colorectal conditions have been included along with 122 recommendations for management. CONCLUSION These guidelines provide an up to date and evidence-based summary of the current surgical knowledge in the management of emergency colorectal conditions and should serve as practical text for clinicians managing colorectal conditions in the emergency setting.

Abstract
Intra-abdominal hypertension has been identified as an independent risk factor for death in critically ill patients. Known risk factors for intra-abdominal hypertension indicate that intra-abdominal pressures should be measured and monitored. The Abdominal Compartment Society has identified medical and surgical interventions to relieve intra-abdominal hypertension or to manage the open abdomen if abdominal compartment syndrome occurs. The purpose of this article is to describe assessments and interventions for managing intra-abdominal hypertension and open abdomen that are within the scope of practice for direct-care nurses. These guidelines provide direction to critical care nurses caring for these patients.

Abstract
Purpose Sedation management of trauma patients after damage control laparotomy (DCL) has not been optimized. We evaluated if shorter sedation exposure was associated with increased proportion of delirium-free/coma-free (DF/CF-ICU) days and change in time to definitive fascial closure (DFC). Methods We reviewed trauma DCL patients at an ACS-verified level I center over 5 years as shorter (SE) or longer than median (LE) sedation exposure. We compared demographics, injury patterns, hemodynamic parameters, and injury severity between groups. We calculated the propensity for each patient to achieve DFC using age, gender, ISS, red blood cell transfusion, bowel discontinuity, abdominal vascular injury, and time to first takeback; we then determined the effect of sedation exposure on rate of DFC by multivariate Cox regression, adjusted for propensity to achieve DFC. We used linear regression adjusted for age, ISS, head-AIS, bowel discontinuity, and vascular injury to determine the effect of sedation exposure on the proportion of DF/CF-ICU days. Results 65 patients (33.8% penetrating) had mean age 41.8 ± 16.0, ISS 27.1 ± 14.2, Head-AIS 1.2 ± 1.6 and median sedation exposure of 2.2 [IQR 0.78, 7.3] days (35 SE and 30 LE). Pattern and severity of solid organ injuries and proportion of small and large bowel and vascular injuries were similar between groups. LE had more abdominal sepsis (23.3% vs 0%, p = 0.003) and enterocutaneous fistula (16.7% vs 0%, p = 0.016), and more ventilator (17.3 ± 12.7 vs 6.1 ± 6.8, p < 0.001), ICU (20.8 ± 14.2 vs 7.2 ± 7.6, p < 0.001), and hospital days (29.6 ± 19.6 vs 13.9 ± 9.0, p < 0.001). DFC was achieved more rapidly in the SE group (2.0 ± 1.5 days vs 3.9 ± 3.7 days [unadjusted], p = 0.023) and SE had a higher proportion of unadjusted DF/CF-ICU days (33.0 ± 32.0% vs 18.1 ± 16.4%, p = 0.020). SE was associated with an increased proportion of adjusted DF/CF-ICU days by multivariate linear regression (13.1% [95% CI 1.4–24.8%], p = 0.029) and with faster adjusted rate of DFC by multivariate Cox regression (RR 2.28 [95% CI 1.25–4.15, p = 0.007]). Conclusions Shorter sedation exposure is associated with increased proportion of DF/CF-ICU days and more rapid DFC after DCL for trauma.

Outcomes of Exploratory Laparotomy and Abdominal Infections Among Combat Casualties. J Surg Res 2020; 257:285-293. [PMID: 32866669 DOI: 10.1016/j.jss.2020.07.075] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 07/09/2020] [Accepted: 07/11/2020] [Indexed: 01/01/2023]
Abstract
BACKGROUND Abdominal injuries historically account for 13% of battlefield surgical procedures. We examined the occurrence of exploratory laparotomies and subsequent abdominal surgical site infections (SSIs) among combat casualties. METHODS Military personnel injured during deployment (2009-2014) were included if they required a laparotomy for combat-related trauma and were evacuated to Landstuhl Regional Medical Center, Germany, before being transferred to participating US military hospitals. RESULTS Of 4304 combat casualties, 341 (7.9%) underwent laparotomy. Including re-explorations, 1053 laparotomies (median, 2; interquartile range, 1-3; range, 1-28) were performed with 58% occurring within the combat zone. Forty-nine (14.4%) patients had abdominal SSIs (four with multiple SSIs): 27 (7.9%) with deep space SSIs, 14 (4.1%) with a deep incisional SSI, and 12 (3.5%) a superficial incisional SSI. Patients with abdominal SSIs had larger volume of blood transfusions (median, 24 versus 14 units), more laparotomies (median, 4 versus 2), and more hollow viscus injuries (74% versus 45%) than patients without abdominal SSIs. Abdominal closure occurred after 10 d for 12% of the patients with SSI versus 2% of patients without SSI. Mesh adjuncts were used to achieve fascial closure in 20.4% and 2.1% of patients with and without SSI, respectively. Survival was 98% and 96% in patients with and without SSIs, respectively. CONCLUSIONS Less than 10% of combat casualties in the modern era required abdominal exploration and most were severely injured with hollow viscus injuries and required massive transfusions. Despite the extensive contamination from battlefield injuries, the SSI proportion is consistent with civilian rates and survival was high.

Management of Open Abdomen After Trauma Laparotomy: A Comparative Analysis of Dynamic Fascial Traction and Negative Pressure Wound Therapy Systems. World J Surg 2020; 43:3044-3050.

Abstract
BACKGROUND Management of the post-traumatic open abdomen (OA) using negative pressure wound therapy (NPWT) alone is associated with low rates of primary fascial closure. The abdominal reapproximation anchor (ABRA) system exerts dynamic medial fascial traction and may work synergistically with NPWT to facilitate primary fascial closure. METHODS Patients with an OA following trauma laparotomy between 2009 and 2018 were identified from a prospectively maintained institutional database. Patients treated with ABRA in conjunction with NPWT (ABRA) versus NPWT alone (NPWT) were compared in terms of primary fascial closure rate, number of surgeries to closure, tracheostomy duration, length of stay and incidence of entero-atmospheric fistula. Multivariable linear regression was performed to identify predictors of tracheostomy duration. RESULTS We identified 48 patients [ABRA, 12 and NPWT, 36]. The ABRA group was significantly younger (25 vs. 37 years, p = 0.027) and included a lower proportion of males (58% vs. 89%, p = 0.032). Groups were similar with respect to the incidence of hollow viscus injury, injury severity score and abdominal abbreviated injury score. Compared to the NPWT group, the ABRA group had a significantly higher rate of primary fascial closure (100% vs. 28%, p < 0.001), fewer surgeries to abdominal closure (2 vs. 2.5, p = 0.023) and shorter duration of tracheostomy (15.5 vs. 36 days, p = 0.008). There were no differences in length of stay or incidence of entero-atmospheric fistula. On multivariable linear regression, ABRA placement was an independent predictor of shorter tracheostomy duration, after adjusting for covariates (β = - 0.294, p = 0.036). CONCLUSION For the post-traumatic OA, ABRA coupled with NPWT achieves a higher rate of primary fascial closure compared to NPWT alone, while requiring fewer surgeries and a shorter duration of tracheostomy.

Abstract
BACKGROUND There is limited characterization of patients with enteric fistula. Our objective is to determine the incidence of the disease, and characterize demographics, healthcare costs, co-diagnoses, and procedures in this population. METHODS The National Inpatient Sample database 2004-2014 was queried to identify patients with enteric fistula using ICD-9 code 569.81. RESULTS There were 317,000 admissions with a diagnosis of enteric fistula from 2004 to 2014, accounting for 230,000 hospital days annually. Costs totaled $500 million with charges of $1.5 billion annually. Inpatient mortality is 4.1%. Patients had significant comorbidities and 3 procedures or surgical interventions per admission. CONCLUSIONS This descriptive study elucidates the impact of enteric fistula on patients and hospitals by characterizing incidence, clinical associations, and admission characteristics. There is significant financial impact with 28,000 admissions and $500 million dollars in annual costs. This study lays the groundwork for future research by characterizing the impact of enteric fistula.

Abstract
Although the use of damage control laparotomy (DCL) is well established, the effect of damage control resuscitation (DCR) on the management of open abdomens is relatively poorly studied. The aim of the present study was to determine the predictors for failure to achieve primary fascial closure (PFC) after DCL in the setting of a massive transfusion (MT) and DCR. This is a retrospective review over a 12-year period of all patients that underwent MT and DCL. Patients who achieved PFC were compared with those who did not (NPFC). Student's t tests were used to compare the two groups. A multiple logistic regression model was performed to identify independent risk factors for failure to attain PFC. Of 174 patients, 101 achieved PFC. Mean (6 standard deviation) age was 35.6 ± 14.9 years for PFC and 36.3 ± 14.0 years for NPFC ( P = 0.75). Admission Glasgow Coma Scale score was 11.4 ± 4.6 for PFC and 10.6 ± 5.0 for NPFC ( P = 0.25). Initial lactate (7.3 ± 3.8 vs 7.7 ± 4.1, P = 0.50), hemoglobin (11.3 ± 1.9 vs 11.0 ± 2.2, P = 0.43), systolic blood pressure (108 ± 44 vs 107 ± 35, P = 0.82), Injury Severity Score (34 ± 14 vs 36 ± 15, P = 0.32), and abdominal Abbreviated Injury Score (3.6 ± 1.1 vs 3.9 ± 1.0, P = 0.13) were similar between the two groups. There was no difference in total blood products administered at 24 hours (46 ± 26 vs 49 ± 29 units, P = 0.45). Logistic regression identified increasing volume of crystalloid at 24 hours (odds ratio, 0.86; 95% confidence interval, 0.74 to 0.99; P = 0.047), earlier operative year (2.1; 1.52 to 2.91; P < 0.001), and increased number of procedures (0.32, 0.18 to 0.58; P < 0.001) as independent predictors for failure to obtain PFC. Injury severity is not associated with failure to achieve PFC, whereas administration of large-volume crystalloid resuscitation, increasing number procedures, and earlier year of DCL are independent predictors for failure to achieve PFC. Application of DCR to DCL techniques results in an improvement in ability to achieve PFC.

Abstract
BACKGROUND To standardize care and promote early fascial closure among patients undergoing emergent laparotomy and temporary abdominal closure (TAC), we developed a protocol addressing patient selection, operative technique, resuscitation strategies, and critical care provisions. We hypothesized that primary fascial closure rates would increase following protocol implementation with no difference in complication rates. STUDY DESIGN We performed a retrospective cohort analysis of 138 adult trauma and emergency general surgery patients who underwent emergent laparotomy and TAC, comparing protocol patients (n = 60) to recent historic controls (n = 78) who would have met protocol inclusion criteria. The protocol includes low-volume 3% hypertonic saline resuscitation, judicious wound vacuum fluid replacement, and early relaparotomy with sequential fascial closure. Demographics, baseline characteristics, illness severity, resuscitation course, operative management, and outcomes were compared. The primary outcome was fascial closure. RESULTS Baseline characteristics, including age, American Society of Anesthesiologists class, and postoperative lactate levels, were similar between groups. Within 48 hours of initial laparotomy and TAC, protocol patients received significantly lower total intravenous fluid resuscitation volumes (9.7 vs. 11.4 L, p = 0.044) and exhibited higher serum osmolarity (303 vs. 293 mOsm/kg, p = 0.001). The interval between abdominal operations was significantly shorter following protocol implementation (28.2 vs. 32.2 hours, p = 0.027). The incidence of primary fascial closure was significantly higher in the protocol group (93% vs. 81%, p = 0.045, number needed to treat = 8.3). Complication rates were similar between groups. CONCLUSIONS Protocol implementation was associated with lower crystalloid resuscitation volumes, a transient hyperosmolar state, shorter intervals between operations, and higher fascial closure rates with no difference in complications. LEVEL OF EVIDENCE Therapeutic study, level IV.

Challenge of uncontrolled enteroatmospheric fistulas. Trauma Surg Acute Care Open 2020; 4:e000381.

Abstract
Introduction With the popularization of damage control surgery and the use of the open abdomen, a new permutation of fistula arose; the enteroatmospheric fistula (EAF), an opening of exposed intestine spilling uncontrollably into the peritoneal cavity. EAF is the most devastating complication of the open abdomen. We describe and analyze a single institution’s experience in controlling high-output EAFs in patients with peritonitis. Methods We analyzed 189 consecutive procedures to achieve and maintain definitive control of 24 EAFs in 13 patients between 2006 and 2017. EAFs followed surgery for either trauma (seven patients) or non-traumatic abdominal conditions (six patients). All procedures were mapped onto an operative timeline and analyzed for: success in achieving definitive control, number of reoperations, and feasibility of bedside procedures in the surgical intensive care unit. The end point was controlled enteric drainage through a healed abdominal wound. Results There was a mean delay of 8.5 days (range 2–46 days) from the index operation until the EAF was identified. Most EAFs required several attempts (mean: 2.7 per patient, range 1–7) until definitive control was achieved. Multiple reoperations were then required to maintain control (mean: 13). While the most effective techniques were endoscopic (1) and proximal diversion (1), these were applicable only in select circumstances. A ‘floating stoma’ where the fistula edges are sutured to an opening in a temporary closure device, while technically effective, required multiple reoperations. Tube drainage through a negative pressure dressing (tube vac) required the most maintenance usually through bedside procedures. Primary closure almost always failed. Twelve of the 13 patients survived. Conclusion An EAF is a highly complex surgical challenge. Successful source control of the potentially lethal ongoing peritonitis requires tenacity and tactical flexibility. The appropriate control technique is often found by trial and error and must be creatively tailored to the individual circumstances of the patient.

Abstract
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.

Abstract
BACKGROUND Open abdomen is the cornerstone of damage control strategies in acute care and trauma surgery. The role of BMI has not been well investigated. The aim of the study was to assess the role of BMI in determining outcomes after open abdomen. METHODS This is an analysis of patients recorded into the International Register of Open Abdomen; patients were classified in two groups according to BMI using a cutoff of 30 kg/m2. The primary outcome was in-hospital mortality; secondary outcomes were primary fascia closure rate, length of treatment, complication rate, entero-atmospheric fistula rate and length of ICU stay. RESULTS A total of 591 patients were enrolled from 57 centers, and obese patients were 127 (21.5%). There was no difference in mortality between the two groups; complications developed during the open treatment were higher in obese patients (63.8% vs. 53.4%, p = 0.038) while post-closure complications rate was similar. Obese patients had a significantly longer duration of the open treatment (9.1 ± 11.5 days vs. 6.3 ± 7.5 days; p = 0,002) and lower primary fascia closure rate (75.5% vs. 89.5%; p < 0,001). No differences in fistula rate were found. There was a linear correlation between the duration of open abdomen and the BMI (Pearson's linear correlation coefficient = 0,201; p < 0,001). CONCLUSIONS Open abdomen in obese patients seems to be safe as in non-obese patients with similar mortality; however, in obese patients the length of open abdomen is significantly higher with higher complication rate, longer ICU length of stay and lower primary fascia closure rate.

Abstract
Treatment of an open abdomen (OA) wound combined with an intestinal fistula is a challenge in the clinic. Here, inspired by the antibacterial activity of graphene (G) and its derivatives, we present a hybrid patch based on the ability of graphene and polycaprolactone (PCL) to kill bacteria and save the cells in a wound. Benefiting from the antibacterial ability of graphene oxide (GO), cells could survive in the presence of bacteria. With the increased ability to protect cells, this patch accelerated wound healing in an OA and intestinal fistula wound model. Additionally, the sub-acute toxicity score showed no extra damage to organs. In conclusion, the employment of the hybrid material for an OA and an intestinal fistula wound healing is encouraging. A hybrid patch based on graphene oxide and polycaprolactone electrospun was generated for open abdomen and fistula wound. The application of the hybrid patch could save the cells from bacteria which contribute to accelerating wound healing.

Abstract
BACKGROUND Patients with an open abdomen after trauma or emergency surgery may benefit from reduced sedation and chemical paralysis. We studied the effect of attending surgeon experience on sedation depth and paralytic use, as well as enteral nutrition and time between laparotomies. METHODS We performed an institutional review board-approved survey (Sedation Level after Emergent ExLap without Primary Fascial Closure) of the senior and active Eastern Association for the Surgery of Trauma membership using Qualtrics (Qualtrics, Inc, Provo, UT). We obtained 393/1,655 responses (23.7%). Spearman's rho was used for ordinal data, and multivariate logistic regression was used to adjust for trauma center level and presence of trainees in the relationship between surgeon experience and use of deep sedation. RESULTS Surgeon experience was associated with deep sedation (Richmond Agitation and Sedation Score ≤-3, P = .001) and chemical paralysis (P = .001). Surgeon experience was associated with less concern about delirium and more concern for evisceration as the reason for sedation depth (P = .001) and for paralysis (P = .001). Using multivariate logistic regression, surgeon experience was associated with deep sedation (odds ratio 3.6 [95% confidence interval 1.3, 10.4], P = .017 for ≥20 years; odds ratio 3.5 [95% confidence interval 1.1, 10.4], P = .025 for 15-20 years). Trauma center level was also significant (odds ratio 7.2 for Richmond Agitation and Sedation Score ≤-3 [95% confidence interval 1.7, 31.0], P = .008 for level III/IV versus level I/II). Increased surgeon experience was associated with delay of commencement of enteral feeds until return of bowel function (P = .013). Few respondents indicated willingness to extubate or mobilize open abdomen patients. Experienced surgeons were likely to wait for a defined time rather than for normalization of resuscitation markers to perform the first takeback laparotomy (P = .047) and waited longer between subsequent laparotomies (P = .004). CONCLUSION There were significant variations in practice among respondents based on the length of time since their last residency or fellowship, including variations that deviate from current best practice for management of patients with an open abdomen.

Abstract
BACKGROUND Our objective was to establish the safety of 3% hypertonic saline (HTS) resuscitation for trauma and acute care surgery patients undergoing emergent laparotomy and temporary abdominal closure (TAC) with the hypothesis that HTS administration would be associated with hyperosmolar hypercholoremic acidosis, lower resuscitation volumes, and higher fascial closure rates, without adversely affecting renal function. METHODS We performed a retrospective cohort analysis of 189 trauma and acute care surgery patients who underwent emergent laparotomy and TAC, comparing patients with normal baseline renal function who received 3% HTS at 30 mL/h (n = 36) to patients with standard resuscitation (n = 153) by baseline characteristics, resuscitation parameters, and outcomes including primary fascial closure and Kidney Disease: Improving Global Outcomes stages of acute kidney injury. RESULTS The HTS and standard resuscitation groups had similar baseline illness severity and organ dysfunction, though HTS patients had lower serum creatinine at initial laparotomy (1.2 mg/dL vs. 1.4 mg/dL; p = 0.078). Forty-eight hours after TAC, HTS patients had significantly higher serum sodium (145.8 mEq/L vs. 142.2 mEq/L, p < 0.001), chloride (111.8 mEq/L vs. 106.6 mEq/L, p < 0.001), and osmolarity (305.8 mOsm/kg vs. 299.4 mOsm/kg; p = 0.006), and significantly lower arterial pH (7.34 vs. 7.38; p = 0.011). The HTS patients had lower intravenous fluid (IVF) volumes within 48 hours of TAC (8.5 L vs. 11.8 L; p = 0.004). Serum creatinine, urine output, and kidney injury were similar between groups. Fascial closure was achieved for 92% of all HTS patients and 77% of all standard resuscitation patients (p = 0.063). Considering all 189 patients, higher IVF resuscitation volumes within 48 hours of TAC were associated with decreased odds of fascial closure (odds ratio, 0.90; 95% confidence interval, 0.83-0.97; p = 0.003). CONCLUSION Hypertonic saline resuscitation was associated with the development of a hypernatremic, hyperchloremic, hyperosmolar acidosis, and lower total IVF resuscitation volumes, without adversely affecting renal function. These findings may not be generalizable to patients with baseline renal dysfunction and susceptibility to hyperchloremic acidosis-induced kidney injury. LEVEL OF EVIDENCE Prognostic study, level II.

Abstract
Objective To evaluate the effect of imbibed fibrinogen gauze on survival, bleeding and healing in liver trauma. Methods This animal experimental study was conducted on 20 adult male Sprague-Dawley rats; with a mean weight of 300±50 gram; divided into two groups. Grade IV injury was induced to the subjects' liver. Then, the bleeding site was packed with simple gauze in the control group, and imbibed fibrinogen gauze in the experimental group. All animals were re-evaluated for liver hemostasis 48 hours after the initial injury. Bleeding in the intra peritoneal cavity was measured using Tuberculosis Syringe in the first and second operations. Subjects were followed-up for 14 days. Eventually, the rats were sacrificed and their livers were sent to a lab for stereological assessment. Statistical comparisons were performed via Mann-Whitney U-test using SPSS. P-Values less than 0.05 were considered to be statistically significant. Results Half of the rats in the control group died, while all the rats in the imbibed fibrinogen gauze group survived after two weeks (p= 0.032). Bleeding in the imbibed fibrinogen gauze was significantly less than control group, 48 hours' post-surgery (p<0.001). According to the stereological results, granulation tissue in the imbibed fibrinogen gauze group were more than the control group (P= 0.032). Also, fibrosis in the imbibed fibrinogen gauze group were more than the control group (P= 0.014). Conclusion Our study indicated that imbibed fibrinogen gauze can potentially control liver bleeding and improve survival through increasing granulation tissue and fibrosis in injured liver.

Accurate risk stratification for development of organ/space surgical site infections after emergent trauma laparotomy. J Trauma Acute Care Surg 2019; 86:226-231.

Abstract
BACKGROUND Organ/space surgical site infection (OS-SSI) develops frequently after trauma laparotomies and is associated with significant morbidity. No valid model exists to accurately risk-stratify the probability of OS-SSI development after emergent laparotomy. Risk stratification for OS-SSI in these patients could guide promising, but unproven, interventions for OS-SSI prevention, such as more frequent dosing of intraoperative antibiotics or direct peritoneal resuscitation. We hypothesize that in trauma patients who undergo emergent laparotomy, probability of OS-SSI can be accurately estimated using patient data available during the index operation. METHODS Retrospective review was performed on a prospectively maintained database of emergent trauma laparotomies from 2011 to 2016. Patient demographics and risk factors for OS-SSI were collected. We performed Bayesian multilevel logistic regression to develop the model based on a 70% training sample. Evaluation of model fit using area under the curve was performed on a 30% test sample. The Bayesian approach allowed the model to address clustering of patients within physician while implementing regularization to improve predictive performance on test data. RESULTS One hundred seventy-two (15%) of 1,171 patients who underwent laparotomy developed OS-SSI. Variables thought to affect development of surgical site infections and were available to the surgeon near the conclusion of the trauma laparotomy were included in the model. Two variables that contributed most to OS-SSIs were damage-control laparotomy and colon resection. The area under the curve of the predictive model validated on the test sample was 0.78 (95% confidence interval, 0.71-0.85). CONCLUSION Using a combination of factors available to surgeons before the end of an emergent laparotomy, the probability of OS-SSI could be accurately estimated using this retrospective cohort. A Web-based calculator is under design to allow the real-time estimation of probability of OS-SSI intraoperatively. Prospective validation of its generalizability to other trauma cohorts and of its utility at the point of care is required. LEVEL OF EVIDENCE Prognostic study, level IV.

Open abdomen and entero-atmospheric fistulae: An interim analysis from the International Register of Open Abdomen (IROA). Injury 2019; 50:160-166. [PMID: 30274755 DOI: 10.1016/j.injury.2018.09.040] [Citation(s) in RCA: 40] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2018] [Revised: 08/26/2018] [Accepted: 09/20/2018] [Indexed: 02/08/2023]
Abstract
INTRODUCTION No definitive data describing associations between cases of Open Abdomen (OA) and Entero-atmospheric fistulae (EAF) exist. The World Society of Emergency Surgery (WSES) and the Panamerican Trauma Society (PTS) thus analyzed the International Register of Open Abdomen (IROA) to assess this question. MATERIAL AND METHODS A prospective analysis of adult patients enrolled in the IROA. RESULTS Among 649 adult patients with OA 58 (8.9%) developed EAF. Indications for OA were peritonitis (51.2%) and traumatic-injury (16.8%). The most frequently utilized temporary abdominal closure techniques were Commercial-NPWT (46.8%) and Bogotà-bag (21.9%). Mean OA days were 7.9 ± 18.22. Overall mortality rate was 29.7%, with EAF having no impact on mortality. Multivariate analysis associated cancer (p = 0.018), days of OA (p = 0.003) and time to provision-of-nutrition (p = 0.016) with EAF occurrence. CONCLUSION Entero-atmospheric fistulas are influenced by the duration of open abdomen treatment and by the nutritional status of the patient. Peritonitis, intestinal anastomosis, negative pressure and oral or enteral nutrition were not risk factors for EAF during OA treatment.

Abstract
BACKGROUND Intestinal disruption following blunt abdominal trauma (BAT) continues to be associated with significant morbidity and mortality despite the advances in resuscitation and management. We aim to analyze the management and postoperative outcomes of intestinal injuries secondary to blunt abdominal trauma. METHOD We retrospectively reviewed all adult patients with intestinal injuries who underwent laparotomy for BAT between December 2008 and September 2015 at Level I trauma center. Data included demographics, mechanism of injury, site (small and large intestine), type of repair, (enterorrhaphy and resection with anastomosis), type of anastomosis (hand-sewn or stapled anastomoses), need for damage control laparotomy, postoperative complications, and mortality. Data were analyzed and compared for postoperative complications. RESULTS A total of 160 patients with bowel injuries were included with mean age of 33 years, and 95.6% were males. Injuries involving small bowel, colon, and combined small and large bowel were found in 57.5%, 33.1%, and 9.4%, respectively, with only two duodenal and one rectal injury cases. There were 46.3% patients underwent debridement and primary closure, while 53.8% required resection with anastomosis. Anastomoses were side-to-side stapled in 79.1%, hand-sewn in 14.0%, and combination in 7.0% of patients. The overall postoperative complications (17.5%) in terms of wound infection (n = 16), intra-abdominal abscess (n = 13), and anastomotic leak (n = 13). There were two deaths occurred because of bowel injury complications. Need for blood transfusion, high serum lactate, number of re-laparotomies, and mortality were significantly associated with postoperative complications. On multivariate regression analysis, serum lactate (OR 1.27; 95% CI 1.01-1.60; p = 0.04) was found to be the independent predictor of postoperative complications. CONCLUSION Repair of traumatic blunt bowel injury remains a surgical challenge.

Abstract
Introduction The core concepts of damage control and open abdomen in trauma surgery have been expanding for emergent general surgery. Temporary closures allow ease of access to the abdominal cavity for source control.The aim of the current study was to assess the outcomes of patients who underwent open abdomen management for acute abdominal conditions and evaluate risk factors for worse outcomes and inability of fascial closure during the initial hospitalization. Methods We conducted a retrospective analysis of 101 patients submitted to laparostomy in a single institution from January 2009 to March 2017. The evaluated outcomes were mortality, local morbidity, and rate of primary fascial closure. Results The most common indications for open abdomen were bowel perforation, bowel ischemia, and necrotizing pancreatitis. Global in-hospital mortality rate was 62.4%. For the 37 patients discharged from the hospital, a definitive abdominal closure was attained in 28.Multivariable logistic regression analysis revealed that people older than 60 years of age and with Acute Physiology and Chronic Health Evaluation (APACHE II) scores over 18.5 had higher in-hospital mortality rates. Definitive fascial closure was statistically associated with a lower number of re-interventions and ICU stay. Conclusions Open abdomen management may be appropriate in these critically ill patients; however, it continues to be associated with significantly high mortality, especially in elder patients and with higher APACHE II scores. Recognition of risk factors for fascia closure failure should promote the investigation for a tailored surgical approach in these patients.

"Second-look" laparotomy: warranted, or contributor to excessive open abdomens? Eur J Trauma Emerg Surg 2018; 45:705-711. [PMID: 29947847 DOI: 10.1007/s00068-018-0968-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2017] [Accepted: 05/31/2018] [Indexed: 11/30/2022]
Abstract
INTRODUCTION The overuse of temporary abdominal closure and second look (SL) laparotomy in emergency general surgery (EGS) cases has been questioned in the recent literature. In an effort to hopefully decrease the number of open abdomen (OA) patients, we hypothesize that reviewing our cases, many of these SL patients could be managed with single-stage operative therapy and thus decrease the number of OA patients. METHODS This is a retrospective review of prospectively collected data from Jun 2013-Jun 2014, evaluating EGS patients managed with an OA who required bowel resection in either index or SL laparotomy. Demographics, clinical variables, complications and mortality were collected. Fisher's exact t test was used for statistical analysis. RESULTS During this time frame, 96 patients were managed with OA and 59 patients required a bowel resection. 55 (57%) of those required one bowel resection at the index operation with 4 (4.2%) only requiring one bowel resection at the second operation. In the patients requiring bowel resections, 18 (30%) required a resection at SL. At SL laparotomy, resection was required for questionably viable bowel at the index operation 60% (11), whereas 39% (7) had normal appearing bowel. Indications for resection at SL laparotomy included evolution of existing ischemia, new onset ischemia, staple line revision, and "other". 23 patients (39%) were hemodynamically unstable, contributing to the need for temporary abdominal closure. In the multivariate analysis, preoperative shock was the only predictor of need for further resection. Complications and mortality were similar in both groups. CONCLUSION Almost one-fifth of the patients undergoing SL laparotomy for open abdomen required bowel resections, with 6.8% of those having normal appearing bowel at index operation, therefore in select EGS patients, SL laparotomy is a reasonable strategy.
