Revisiting abdominal closure in mesenteric ischemia: is there an association with outcome? Eur J Trauma Emerg Surg 2023; 49:2017-2024.

Abstract
PURPOSE Current guidelines advocate liberal use of delayed abdominal closure in patients with acute mesenteric ischemia (AMI) undergoing laparotomy. Few studies have systematically examined this practice. The goal of this study was to evaluate the effect of delayed abdominal closure on postoperative morbidity and mortality in patients with AMI. METHODS We performed a retrospective cohort study of the ACS-NSQIP 2013-2017 registry. We included patients with a diagnosis of AMI undergoing emergency laparotomy. Patients were divided into two groups based on the type of abdominal closure: (1) delayed fascial closure (DFC) when no layers of the abdominal wall were closed and (2) immediate fascial closure (IFC) if deep layers or all layers of the abdominal wall were closed. Propensity score matching was performed based on comorbidities, pre-operative, and operative characteristics. Univariable analysis was performed on the matched sample. RESULTS The propensity-matched cohort consisted of 1520 patients equally divided into the DFC and IFC groups. The median (IQR) age was 68 (59-77), and 836 (55.0%) were female. Compared to IFC, the DFC group showed increased in-hospital mortality (38.9% vs. 31.6%, p = 0.002), 30-day mortality (42.4% vs. 36.3%, p = 0.012), and increased risk of respiratory failure (59.5% vs. 31.2%, p < 0.001). CONCLUSIONS The delayed fascial closure technique was associated with increased mortality compared to immediate fascial closure. These findings do not support the blanket incorporation of delayed closure in mesenteric ischemia care or its previously advocated liberal use.

Abstract
OBJECTIVE To estimate the incidence of acute mesenteric ischaemia (AMI), proportions of its different forms and short-term and long-term mortality. DESIGN Systematic review and meta-analysis. DATA SOURCES MEDLINE (Ovid), Web of Science, Scopus and Cochrane Library were searched until 26 July 2022. ELIGIBILITY CRITERIA Studies reporting data on the incidence and outcomes of AMI in adult populations. DATA EXTRACTION AND SYNTHESIS Data extraction and quality assessment with modified Newcastle-Ottawa scale were performed using predeveloped standard forms. The outcomes were the incidence of AMI and its different forms in the general population and in patients admitted to hospital, and the mortality of AMI in its different forms. RESULTS From 3064 records, 335 full texts were reviewed and 163 included in the quantitative analysis. The mean incidence of AMI was 6.2 (95% CI 1.9 to 12.9) per 100 000 person years. On average 5.0 (95% CI 3.3 to 7.1) of 10 000 hospital admissions were due to AMI. Occlusive arterial AMI was the most common form constituting 68.6% (95% CI 63.7 to 73.2) of all AMI cases, with similar proportions of embolism and thrombosis.Overall short-term mortality (in-hospital or within 30 days) of AMI was 59.6% (95% CI 55.5 to 63.6), being 68.7% (95% CI 60.8 to 74.9) in patients treated before the year 2000 and 55.0% (95% CI 45.5 to 64.1) in patients treated from 2000 onwards (p<0.05). The mid/long-term mortality of AMI was 68.2% (95% CI 60.7 to 74.9). Mortality due to mesenteric venous thrombosis was 24.6% (95% CI 17.0 to 32.9) and of non-occlusive mesenteric ischaemia 58.4% (95% CI 48.6 to 67.7). The short-term mortality of revascularised occlusive arterial AMI was 33.9% (95% CI 30.7 to 37.4). CONCLUSIONS In adult patients, AMI is a rarely diagnosed condition with high mortality, although with improvement of treatment results over the last decades. Two thirds of AMI cases are of occlusive arterial origin with potential for better survival if revascularised. PROSPERO REGISTRATION NUMBER CRD42021247148.

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
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. LEVEL OF EVIDENCE Therapeutic study, level IV.

Abstract
OBJECTIVE Acute mesenteric ischemia is a disease with high morbidity and mortality, and it is traditionally treated with open surgery. Endovascular therapy and hybrid techniques are alternative treatments that are also currently available. We performed a meta-analysis to evaluate the outcomes of the different treatment approaches in the last 20 years. METHODS Studies on acute mesenteric ischemia that were indexed in PubMed, Embase, and MEDLINE databases (from January 1, 2000, to April 1, 2021) were reviewed. All related retrospective observational studies and case series were included. A random-effects model was used to calculate pooled estimates, and the results were reported as proportions and 95% confidence intervals (CIs). RESULTS In our study, a total of 2369 patients (in 39 studies) underwent endovascular, open surgery, or retrograde open mesenteric stenting. The pooled mortality estimates for open surgery, endovascular therapy, and retrograde open mesenteric stenting were 40% (95% CI, 0.33-0.47; I2 = 84%), 26% (95% CI, 0.19-0.33; I2 = 33%), and 32% (95% CI, 0.21-0.44; I2 = 26%), respectively. CONCLUSIONS The mortality associated with open surgical treatment, endovascular therapy, and retrograde open mesenteric stenting tend to be similar in the last 20 years.

Abstract
Acute mesenteric ischemia is considered uncommon, but it appears to be more frequent cause of acute abdomen than appendicitis or ruptured abdominal aortic aneurysm in elderly patients. Surgical treatment without revascularization is associated with high overall mortality, up to 80%. The modern treatment of acute mesenteric ischemia requires collaboration of gastrointestinal surgeons, vascular surgeons, and interventional radiologists. Early revascularization may reduce the overall mortality associated with acute mesenteric ischemia by up to 50%. Clinical suspicion and contrast-enhanced computed tomography performed at early stage are keys to improve outcomes of acute mesenteric ischemia treatment. This review summarizes what the acute care surgeon needs to know about acute mesenteric ischemia with special emphasis on slowly progressing "acute on chronic" mesenteric ischemia.

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
PURPOSE OF REVIEW Mesenteric ischemia (MI), both acute (AMI) and chronic (CMI), is a challenging diagnosis to make, and early diagnosis and treatment are vital to improve outcomes. This manuscript summarizes the most up to date information on diagnosis and treatment of these disorders. RECENT FINDINGS There have been several significant advancements in the computed tomography (CT) diagnostic imaging as well as medical and endovascular management of AMI and CMI. In appropriate populations, endovascular interventions appear superior to open surgical management with lower mortality, morbidity, and cost of care. Efficient clinical identification and targeted testing are essential to diagnose AMI and CMI. Aggressive resuscitation and early endovascular (or in select cases, surgical) intervention improve outcomes in those with AMI. In those with CMI, considering this on the differential diagnosis and imaging appropriately can identify those that might benefit from intervention and halt progression to acute episodes.

Abstract
BACKGROUND Damage control surgery (DCS) was a major paradigm change in the management of critically ill trauma patients and has gradually expanded in the general surgery arena, but data in this setting are still scarce. The study aim was to evaluate outcomes of DCS in patients with general surgery emergencies. METHODS Between 2005 and 2015, 164 patients (104 men, age 66) underwent DCS for non-traumatic abdominal emergencies. The decision to perform DCS was triggered by the presence of at least one trauma DCS criterion: hypotension (<70 mmHg), hypothermia (<35 °C), acidosis (pH < 7.25), coagulopathy (INR ≥ 1.7) and massive (>5 RBC) transfusion. Statistical tests were performed to identify risk factors for operative mortality. Observed outcomes were compared to those predicted by commonly employed scores (APACHE II, POSSUM, P-POSSUM, SAPS II). RESULTS DCS was performed for acute mesenteric ischemia (n = 68), peritonitis (n = 44), pancreatitis (n = 28), bleeding (n = 14) and other (n = 10). Abdominal compartment syndrome was associated in 52 patients (32%). Seventy-four (45%) patients died and 150 patients (91%) experienced complications. On multivariate analysis, age (p = 0.018) and INR ≥ 1.7 (p = 0.001) were independent predictors of mortality. Mortality was 24% (13/55), 48% (22/46) and 62% (39/63) in patients with one, two and ≥3 DCS criteria, respectively. Comparison of observed and score-predicted mortality suggested DCS use resulted in significant survival benefit of the whole cohort and of patients with pancreatitis and postoperative peritonitis. CONCLUSIONS DCS can be lifesaving in critically ill patients with general surgery emergencies. Patients with peritonitis and acute pancreatitis are those who benefit most of the DCS approach.

Abstract
BACKGROUND Damage control surgery and open abdomen (OA) have been extensively used in the severe traumatic patients. However, there was little information when extended to a nontrauma setting. The purpose of this study was to evaluate whether the liberal use of OA as a damage control surgery adjunct improved the clinical outcome in acute superior mesenteric artery occlusion patients. STUDY DESIGN A single-center, retrospective cohort review was performed in a national tertiary surgical referral center. RESULTS Forty-four patients received OA (OA group) and 65 patients had a primary fascial closure (non-OA group) after diagnosed as peritonitis secondary to acute superior mesenteric artery occlusion from January, 2005 to June, 2016. Revascularization was achieved through endovascular aspiration embolectomy, open embolectomy, or percutaneous stent. No difference of bowel resection length was found between groups in the first emergency surgery. However, more non-OA patients (35.4%) required a second-look enterectomy to remove the residual bowel ischemia than OA patients (13.6%, P<0.05). OA was closed within a median of 7 days (4 to 15 d). There was a mean of 134 cm residual alive bowel in OA, whereas 96 cm in non-OA. More non-OA patients suffered from intra-abdominal sepsis (23.1% vs. 6.8%, P<0.01), intra-abdominal hypertension (31% vs. 0, P<0.01), and acute renal failure (53.8% vs. 31.8%, P<0.05) than OA group after surgery. Short-bowel syndrome occurred infrequently in OA than non-OA patients (9.1% vs. 36.9%, P<0.01). OA significantly decreased the 30-day (27.3% vs. 52.3%, P<0.01) and 1-year mortality rate (31.8 % vs. 61.5%, P<0.01) compared with non-OA group. CONCLUSIONS Liberal use of OA, as a damage control adjunct avoided the development of intra-abdominal hypertension, reduced sepsis-related complication, and improved the clinical outcomes in peritonitis secondary to acute SMA occlusion.

Abstract
The modern treatment of acute mesenteric ischemia (AMI) requires seamless collaboration of gastrointestinal surgeons, vascular surgeons, and interventional radiologists. The treatment strategy is straightforward aiming at rapid restoration of blood flow to the intestine. Bowel resection is performed on demand. The first thing to consider is the patient's clinical condition at presentation, whether there are signs of peritonitis or not, and whether the patient is hemodynamically stable or not. Second, there are four etiologies of AMI that need to be distinguished as they differ in treatment: superior mesenteric artery embolism, mesenteric arterial occlusive disease, mesenteric venous thrombosis, and non-occlusive mesenteric ischemia. In this review, we describe the basic vascular and endovascular treatment modalities accompanied by a simple algorithm for the various situations in AMI. Furthermore, the indications for damage control and primary definitive surgery are discussed.

Abstract
BACKGROUND Little data evaluate catheter-directed thrombolysis (CDT) therapy as a sequential treatment of emergent surgery for patients with acute superior mesenteric venous thrombosis (ASMVT). We compared the outcomes of ASMVT patients receiving CDT via superior mesenteric artery (SMA) with those who had systemic anticoagulation after emergent laparotomy. METHODS A single-center retrospective study of ASMVT patients receiving emergent laparotomy from May 2012 to April 2014 was performed. Patients in group I had postoperative systemic anticoagulation and patients in group II underwent postoperative CDT. The demography, etiology, imaging features, clinical outcomes, and complications were compared. Moreover, univariate analysis was performed to identify confounding variables of 30-day mortality. RESULTS Thirty-two patients (20 males, mean age of 44.9 ± 10.6 years) were included, 17 in group I and 15 in group II. No significant differences of demographic data, etiology, baseline value, and perioperative comorbidity were found. The rate of complete thrombus removal was significantly higher in group II than group I (29.4% vs. 80.0%, P = 0.001). The second-look laparotomy and repeat bowel resection (58.8% vs. 13.3%, P = 0.002) were required in fewer patients in group II (20.0% vs. 70.6%, P = 0.001). The incidence of short-bowel syndrome (SBS; 41.2% vs. 6.7%, P = 0.001) and 30-day mortality (41.2% vs. 6.7%, P = 0.001) were lower in group II. The 1-year survival was also better in group II (52.9% vs. 93.3%, P = 0.014). The incidence of massive abdominal hemorrhage requiring blood transfusion and surgical intervention was 11.8% in group I and 20.0% in group II (P = 0.645). The age, serum D-dimer level, SBS, and postoperative CDT were significant risk factors of 30-day mortality in this study. CONCLUSIONS For ASMVT patients receiving emergent surgery and intraoperative thrombectomy, the algorithm with postoperative CDT via SMA is associated with more favorable clinical outcome compared with systemic anticoagulation.

Abstract
PURPOSE Acute mesenteric ischaemia (AMI) accounts for about 1:1000 acute hospital admissions. Untreated, AMI will cause mesenteric infarction, intestinal necrosis, an overwhelming inflammatory response and death. Early intervention can halt and reverse this process leading to a full recovery, but the diagnosis of AMI is difficult and failure to recognize AMI before intestinal necrosis has developed is responsible for the high mortality of the disease. Early diagnosis and prompt treatment are the goals of modern therapy, but there are no randomized controlled trials to guide treatment and the published literature contains a high ratio of reviews to original data. Much of that data comes from case reports and often small, retrospective series with no clearly defined treatment criteria. METHODS A study group of the European Society for Trauma and Emergency Surgery (ESTES) was formed in 2013 with the aim of developing guidelines for the management of AMI. A comprehensive literature search was performed using the Medical Subject Heading (MeSH) thesaurus keywords "mesenteric ischaemia", "bowel ischaemia" and "bowel infarction". The bibliographies of relevant articles were screened for additional publications. After an initial systematic review of the literature by the whole group, a steering group formulated questions using a modified Delphi process. The evidence was then reviewed to answer these questions, and recommendations formulated and agreed by the whole group. RESULTS The resultant recommendations are presented in this paper. CONCLUSIONS The aim of these guidelines is to provide recommendations for practice that will lead to improved outcomes for patients.

Abstract
Background: Acute mesenteric ischemia (AMI) due to a sudden loss or decrease in blood perfusion to the mesentery represents a highly lethal condition. However, the optimal surgical management remains debatable and merits a more clear recommendation based on a higher level of evidence. Methods: A systematic review of articles published between 2000 and 2013 was performed. Patients were divided into endovascular treatment (ET), open surgery (OS), and hybrid technique (HT) groups. Data of patients’ demographics, procedural information, clinical outcomes including mortality, morbidity, primary patency rate, technique success, primary intestinal resection rate, and second-look laparotomy rate, and follow-up were all retrieved. Comparison between the ET and the OS groups was made using 2-sided Student t test and 2-sided χ2 test or Fisher exact test where appropriate. Results: Twenty-eight articles with a total of 1110 patients were included for the review. The ET group had lower in-hospital mortality and morbidity but similar survival rate during follow-up compared to the OS group. The primary patency rate was higher in the ET group. The overall bowel resection rate was lower in the ET group, and nearly every patient in the cohort who required second-look laparotomy required bowel resection. The HT group seemed to have the lowest mortality and acceptable second-look laparotomy rate and morbidity. Comparison between the HT group and other groups was not possible due to the limited number of cases available for review. Conclusion: Endovascular treatment may serve as a first-line therapy for select patients when there is a low suspicion for intestinal necrosis. Open surgery should be reserved for emergency conditions requiring exploratory laparotomy. Hybrid technique may be an especially effective approach for treating AMI, with low morbidity and mortality, although further studies are required comparing it to OS and ET.

Abstract
BACKGROUD Acute superior mesenteric venous thrombosis (ASMVT) is an uncommon but catastrophic abdominal vascular emergency with high rate of intestinal failure and mortality. The retrospective pilot study was performed to assess the effect of a multidisciplinary stepwise management strategy on survival and mesenteric recanalization in an integrated intestinal stroke center (ISC). MATERIALS AND METHODS A modern management strategy performed by multidisciplinary specialists in ISC was evaluated among 43 ASMVT patients that were classified into central vs peripheral type, operative vs nonoperative, early vs late treated group from March 2009 to April 2013. Patients received specific medical therapy, endovascular treatment, damage-control surgery, selective second-look laparotomy, critical care management, and clinical nutrition support in a stepwise way. The demographics, etiology, imaging characteristics, treatment procedures, complications, clinical outcome, and 1-year follow-up data were analyzed and compared. Confounding factors of mortality were identified by univariate and ROC-curve analysis. A single-center experience of over 5years for this modern strategy was also reported. RESULTS The protocol of multidisciplinary stepwise management strategy was followed in all ASMVT patients successfully. The 30-day mortality and recanalization rate were 11.63% and 90.70%. Initial damage-control surgery was carried out in 46.51% patients, with selective second-look laparotomy in 23.26% patients. Endovascular thrombolysis was performed in 83.72% patients initially or postoperatively. Bowel resection was necessary in 18 patients with the length of 100.00 (47.50, 222.50) cm. The incidence of short-bowel syndrome was 13.95%. The rate and length of bowel resection, short-bowel syndrome rate were significantly lower in nonoperative and early-treated groups (P<0.05). During the follow-up survey, 1-year survival was 83.72%, with no additional death or re-thrombosis. CONCLUSION A multidisciplinary stepwise management strategy involving modern surgical and endovascular treatments that focus on early mesenteric recanalization and bowel viability salvage in a specialized ISC could significantly improve the clinical outcome of ASMVT patients.

Abstract
AIM: To determine the optimal initial treatment modality for acute superior mesenteric vein thrombosis (ASMVT) in patients with circumscribed peritonitis.
METHODS: A retrospective review was made of the Vascular Surgery Department’s medical records to identify adult patients (≥ 18 years old) presenting with circumscribed peritonitis and diagnosed with ASMVT by imaging or endoscopic examination. Patients were selected from the time period between October 2009 and October 2012 to assess the overall performance of a new first-line treatment policy implemented in May 2011 for patients with circumscribed peritonitis, which recommends transcatheter thrombolysis with local anticoagulation and endovascular mechanical thrombectomy. Of the 25 patients selected for study inclusion, 12 had undergone emergency surgical exploration (group 1) and 13 had undergone the initial catheter-directed thrombolysis (group 2). Data extracted from each patient’s records for statistical analyses included method of diagnosis, symptoms, etiology and risk factors, thrombus location, initial management, morbidity, mortality, duration and total cost of hospitalization (in Renminbi, RMB), secondary operation, total length of bowel resection, duration of and findings in follow-up, and death/survival.
RESULTS: The two treatment groups showed similar rates of morbidity, 30-d mortality, and 1-year survival, as well as similar demographic characteristics, etiology or risk factors, computed tomography characteristics, symptoms, findings of blood testing at admission, complications, secondary operations, and follow-up outcomes. In contrast, the patients who received the initial non-operative treatment of transcatheter thrombolysis had significantly shorter durations of admission to symptom elimination (group 1: 18.25 ± 7.69 d vs group 2: 7.23 ± 2.42 d) and hospital stay (43.00 ± 13.77 d vs 20.46 ± 6.59 d), and early enteral or oral nutrition restoration (20.50 ± 5.13 d vs 8.92 ± 1.89 d), as well as significantly less total length of bowel resection (170.83 ± 61.27 cm vs 29.23 ± 50.24 cm) and lower total cost (200020.4 ± 91505.62 RMB vs 72785.6 ± 21828.16 RMB) (P < 0.05 for all). Statistical analyses suggested that initial transcatheter thrombolysis is correlated with quicker resolution of the thrombus, earlier improvement of symptoms, stimulation of collateral vessel development, reversal of intestinal ischemia, receipt of localizing bowel resection to prevent short bowel syndrome, shorter hospitalization, and lower overall cost of treatment.
CONCLUSION: For ASMVT patients with circumscribed peritonitis, early diagnosis is key to survival, and non-operative transcatheter thrombolysis is feasible and effective as an initial treatment.

Abstract
BACKGROUND Damage control surgery is a management sequence initiated to reduce the risk of death in severely injured patients presenting with physiological derangement. Damage control principles have emerged as an approach in non-trauma abdominal emergencies in order to reduce mortality compared with primary definitive surgery. METHODS A PubMed/MEDLINE literature review was conducted of data available over the past decade (up to August 2013) to gain information on current understanding of damage control surgery for abdominal surgical emergencies. Future directions for research are discussed. RESULTS Damage control surgery facilitates a strategy for life-saving intervention for critically ill patients by abbreviated laparotomy with subsequent reoperation for delayed definitive repair after physiological resuscitation. The six-phase strategy (including damage control resuscitation in phase 0) is similar to that for severely injured patients, although non-trauma indications include shock from uncontrolled haemorrhage or sepsis. Minimal evidence exists to validate the benefit of damage control surgery in general surgical abdominal emergencies. The collective published experience over the past decade is limited to 16 studies including a total of 455 (range 3-99) patients, of which the majority are retrospective case series. However, the concept has widespread acceptance by emergency surgeons, and appears a logical extension from pathophysiological principles in trauma to haemorrhage and sepsis. The benefits of this strategy depend on careful patient selection. Damage control surgery has been performed for a wide range of indications, but most frequently for uncontrolled bleeding during elective surgery, haemorrhage from complicated gastroduodenal ulcer disease, generalized peritonitis, acute mesenteric ischaemia and other sources of intra-abdominal sepsis. CONCLUSION Damage control surgery is employed in a wide range of abdominal emergencies and is an increasingly recognized life-saving tactic in emergency surgery performed on physiologically deranged patients.

Abstract
BACKGROUND Diagnosis of acute mesenteric ischaemia in the early stages is now possible with modern computed tomography (CT), using intravenous contrast enhancement and imaging in the arterial and/or portal venous phase. The availability of CT around the clock means that more patients with acute mesenteric ischaemia may be treated with urgent intestinal revascularization. METHODS This was a review of modern treatment strategies for acute mesenteric ischaemia. RESULTS Endovascular therapy has become an important alternative, especially in patients with acute thrombotic superior mesenteric artery (SMA) occlusion, where the occlusive lesion can be recanalized either antegradely from the femoral or brachial artery, or retrogradely from an exposed SMA after laparotomy, and stented. Aspiration embolectomy, thrombolysis and open surgical embolectomy, followed by on-table angiography, are the treatment options for embolic SMA occlusion. Endovascular therapy may be an option in the few patients with mesenteric venous thrombosis who do not respond to anticoagulation therapy. Laparotomy is needed to evaluate the extent and severity of visceral organ ischaemia, which is treated according to the principles of damage control surgery. CONCLUSION Modern treatment of acute mesenteric ischaemia involves a specialized approach that considers surgical and, increasingly, endovascular options for best outcomes.

Abstract
Background Although the application of damage control surgery for trauma has been widely reported and defined, similar approach in non-trauma patients has not been well detailed. Methods A retrospective analysis of data from non-trauma patients who underwent emergency laparotomy between May 2006 and December 2008. Demographics, indications for surgery and outcome of patients who had definitive laparotomies (DL) and patients who had abbreviated laparotomies (AL) were compared. Appendectomies were excluded. Results and discussion Two-hundred ninety-one patients (55% males) were included. Thirty-one (10.7%) underwent AL (58% males). Mean age of patients who had DL and AL was 65 and 62.8 years respectively. Peritonitis and mesenteric ischemia were more common indications in patients with AL than DL: 48.4% vs. 30.4% (p = 0.04) and 32.3% vs. 3.5% (p < 0.0001) respectively. Only 29% of patients who had AL were hemodynamically unstable. Mortality rates were 54.8% and 16.5% in patients with AL and DL respectively (p < 0.0001). Patients who died after AL and DL were significantly older than patients who survived (75 vs. 47.3 and 74 vs. 63 years respectively, p < 0.0001). Median hospital stay was 21 and 9 days for patients with AL and DL respectively (p < 0.05). Patients who underwent AL had significantly more wound infections, sepsis and multi-organ failure. Conclusion The philosophy of damage control surgery is applied to non-trauma patients as some of the prerequisites for the decision to elect this strategy are the same. Peritonitis is the most common indication for AL in non-trauma patients.

Abstract
We present two similar cases of massive small bowel infarction in which two different surgical approaches were employed, illustrating the advantages of the staged approach of damage control surgery. This comprises an initial operation, limited to bowel resection and temporary closure of the bowel ends, and a second performed after 48 to 72 hours where the bowel continuity is re-established. We strongly advocate such an approach as it appears to offer a quicker recovery with fewer complications.

Abstract
Acute mesenteric ischemia continues to be associated with high mortality. We hypothesized that delays in surgical consultation and operation are independently associated with increased mortality and sought to identify modifiable characteristics associated with delayed management. We conducted a retrospective cohort study of 72 patients diagnosed with acute mesenteric ischemia. Twenty-six (36%) patients died, of which 14 (54%) had care withdrawn. Delay in operation (>6 hours after surgical consultation) was associated with increased mortality (adjusted OR 3.7; 90% CI, 1.1-12). For patients for whom care was not withdrawn, delay in surgical consultation (>24 hours after disease onset) was associated with increased mortality (adjusted OR, 9.4; 90% CI, 1.3-65), as was delay in operation (adjusted OR, 4.9; 90% CI, 1.1-22). For those managed medically, early surgical consultation was associated with improved mortality (Odds Ratio [OR], 0; 90% Confidence Interval [CI], 0-0.34). Patients with delayed surgical consultation were more likely to have abdominal distension, elevated lactate concentration, acute renal failure, vasopressor administration, and a lack of abdominal pain. The acquisition of CT imaging trended toward an association with delayed surgical consultation ( P = 0.06). We conclude that early surgical consultation is associated with improved outcome even for patients managed without operative intervention, and that CT imaging may delay appropriate care.

Abstract
Abstract
Background
Ischaemia and reperfusion (IR) of the small bowel is involved in many clinical conditions. A key component in IR-induced tissue damage is microvascular dysfunction. The aim was to investigate the role of leucocytes and platelets in capillary flow impediment and tissue damage.
Methods
Anaesthetized rats were subjected to 30 min warm ischaemia of the small bowel, followed by 1 h reperfusion. To elucidate the influence of leucocytes on platelet adhesion, leucocyte–vessel wall interactions induced by IR were prevented by anti-platelet activating factor (PAF) or anti-intercellular adhesion molecule (ICAM)-1. Intravital videomicroscopy was performed and tissue injury was evaluated histologically.
Results
In submucosal venules, IR induced an increase in the median number of interacting leucocytes from 3 to 10 and 20 leucocytes per 100-µm venule segment after 10 and 60 min reperfusion respectively. Anti-PAF or anti-ICAM-1 completely attenuated this increase, resulting in an eightfold improvement in submucosal capillary flow and reduced tissue injury. Shedding of villi no longer occurred. Platelet–vessel wall interactions occurred particularly in submucosal venules, but were not affected by anti-PAF or anti-ICAM-1.
Conclusion
Small bowel IR initiated an inflammatory and thrombotic response in the submucosal layer only. Attenuation of leucocyte adhesion improved submucosal capillary perfusion, preventing shedding of mucosal villi.

Abstract
Evaluation of the elderly patient with acute abdominal pain is sometimes difficult. Various factors can obscure the presentation, delaying or preventing the correct diagnosis and leading to adverse patient outcomes. Clinicians must consider multiple diagnoses, especially those life-threatening conditions that require timely intervention to limit morbidity and mortality. This article reviews abdominal pain in the elderly, discusses the clinical approach, and highlights key diagnostic considerations.
