Acta Anaesthesiol Scand 2018; 62:1321-1326. [PMID: 29797714 DOI: 10.1111/aas.13159] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2018] [Revised: 04/26/2018] [Accepted: 04/27/2018] [Indexed: 12/18/2022]
Abstract
BACKGROUND Corticosteroids are frequently prescribed to critically ill patients. However, their use may increase the risk of gastrointestinal (GI) bleeding, which is associated with morbidity and mortality. Accordingly, we aim to assess whether continued administration of corticosteroids for >24 hours increases the rate of GI bleeding in adult critically ill patients compared to placebo or no treatment. METHODS/DESIGN We will conduct a systematic review of randomized clinical trials with meta-analysis and trial sequential analysis. The participants will be adult (as defined in the included trials) critically ill patients. The intervention will be any corticosteroid administered systematically for >24 hours and the comparator will be placebo or no treatment. The primary outcome will be rate of clinically important GI bleeding. We will systematically search EMBASE, MEDLINE, Medline In-Process, Cochrane Library, Epistemonikos and trial registries for relevant literature, as well as perform a hand search. We will follow the recommendations by the Cochrane Collaboration and the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The risk of systematic errors (bias) and random errors will be assessed and the overall quality of evidence will be evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. DISCUSSION The risk of GI bleeding in adult critically ill patients treated with corticosteroids is unknown. Hence, there is need for a robust systematic review to assess this risk and provide clinicians with a clearer understanding of the strength and limitations of existing data.

Abstract
PURPOSE We aimed to investigate patients with lower gastrointestinal bleeding who presented to the emergency department requiring initial conventional angiography. We report risk-stratified and mesenteric conventional angiography outcomes. METHODS We retrospectively reviewed patients with lower gastrointestinal bleeding between 2001 and 2012. We included all consecutive patients with clinical lower gastrointestinal bleeding with a requirement of further angiography and possible embolization. Patients who had prior interventions or surgery were excluded. RESULTS A total of 88 patients (35 women, 53 men) with a median age of 71 years (range, 23-99 years) were included in the analysis. Conventional angiography was positive and endovascular treatment was intended in 35 patients. Once the source of bleeding was found angiographically, endovascular treatment had a technical success rate of 90.3% and clinical success rate of 71.4%. Overall early rebleeding rate (<30 days) was 14.8% and late rebleeding rate (>30 days) was 13.6%. CONCLUSION Identifying the source of lower gastrointestinal bleeding remains to be a clinical and angiographic challenge. Although we did not observe an association between mortality and clinical success, increased early rebleeding rates were associated with higher mortality rates.

Abstract
Gastrointestinal (GI) arteriovenous malformations (AVMs) are a well-known source of bleeding with colon being the most common site, but they can also occur in rare locations like the esophagus which may present with life threatening bleeding. We report the case of a 51-year-old male with end stage renal disease (ESRD) presenting with hematemesis and acute on chronic anemia. Further investigation showed an esophageal AVM which is an unusual location and it was successfully treated with an endoscopic clip instead of argon plasma coagulation (APC) due to its challenging location and esophageal wall motion from breathing. The patient continued to be asymptomatic without any upper and lower GI bleeding during his 20 months follow up period after the endoscopic management. Review of literature showed only 10 cases of AVMs involving esophagus and the average age of presentation was 52 years with a male predominance. We also provide an overview of those cases in the discussion section below.

Abstract
Diverticulosis is a structural alteration of the colon tissue characterized by the development of pouch-like structures called diverticula. It afflicts a significant portion of the population in Western countries, with a higher prevalence among the elderly. Diverticulosis is believed to be the result of a synergetic interaction between inherent tissue weakness, diet, colonic microstructure, motility, and genetic factors. A validated etiology has, however, not yet been established. Non-surgical treatment is currently lacking due to this poor understanding, and surgical colon resection is the only long-term solution following recurrent complications. With rising prevalence, the burden of diverticulosis on patients and hospital resources has increased over the past several years. More efficient and less invasive treatment approaches are, thus, urgently needed. Animal models of diverticulosis are crucial to enable a preclinical assessment and evaluation of such novel approaches. This review discusses the animal models of diverticulosis that have been proposed to date. The current models require either a significant amount of time to develop diverticulosis, present a relatively low success rate, or seriously deteriorate the animals' systemic health. Recommendations are thus provided to address these pitfalls through the selection of a suitable animal and the combination of multiple risk factors for diverticulosis.

Abstract
BACKGROUND Lower gastrointestinal (GI) bleeding is a common clinical problem in young patients. The management of this disease in patients is challenging. The aim of this study is to compare sigmoidoscopy with full colonoscopy in these patients. MATERIALS AND METHODS In this cross-sectional study, 120 eligible patients under 50 years old with acute rectal bleeding were enrolled. After cleaning the colon, initially the patients underwent sigmoidoscopy. Pain, the comfort of the test by physician and patient, duration of the procedure, and pathologic findings were recorded. The procedure continued until the splenic flexure passed in the ileocecal valve, and this stage was considered as proximal colonoscopy. Pain, easy performance by physician and the patient, duration of procedure, and pathologic findings were recorded in this stage too. The variables in the two stages were compared with each other. RESULTS There were 66 women (55%) and 54 men (45%) and the mean of age was 41 ± 7.9 years. Proximal colonoscopy from splenic flexure to reach cecum was relatively easier for the physician and the patient than sigmoidoscopy (P < 0.001). Furthermore, the time spent to carry out proximal colonoscopy was less than the time taken for sigmoidoscopy (P < 0.001). Pathologic findings recorded in full colonoscopy were more than sigmoidoscopy (P < 0.001). Therefore, full colonoscopy that includes sigmoidoscopy and proximal colonoscopy is relatively easier than sigmoidoscopy for patients, and it also proves more advantageous than sigmoidoscopy for physicians to perform in Iranian patients because of more tortuous and elongated sigmoid colon in these patients. CONCLUSION It is advised to perform full colonoscopy than sigmoidoscopy in young patients with lower GI bleeding.

Abstract
Background/Aims While colonoscopy is indicated in patients >50 years old presenting with hematochezia, its role in those ≤50 remains debatable. This study aims to evaluate the role of colonoscopy in patients presenting with hematochezia who are ≤50 years old. Methods A retrospective review of all patients aged ≤50 years who underwent colonoscopy for hematochezia in 2012 was conducted. Patient demographics, endoscopic details, and histological results were analyzed. Patients were stratified by age to compare differences in outcome. Results A total of 361 patients with a median age of 44 (range, 18-50) years were reviewed. Hemorrhoid (n = 183, 69.6%) was the most common etiology. Seventy-two neoplastic polyps were identified in 48 (13.3%) patients. There was a significantly larger proportion of patients aged 41-50 years who had neoplastic polyps compared to those aged ≤40 (18.8 vs. 3.8%, p ≤ 0.001); 43.8% (n = 28) of the neoplastic polyps found in those aged 41-50 were proximal to the splenic flexure. The only 2 (0.5%) patients with malignancy were aged 41-50 years. Conclusion Performing colonoscopy in patients presenting with hematochezia should be strongly considered for those aged 41-50 years in view of the significant likelihood of underlying neoplastic polyps compared to those aged ≤40 years.

Abstract
Background In recent years major advances have been made in the management of patients with acute lower gastrointestinal bleeding. The aim of this study was to investigate the characteristics and clinical outcome of patients with acute lower gastrointestinal bleeding (ALGIB) treated with an intensive protocol. Methods We analyzed the medical records of 528 patients with ALGIB. All patients after hemodynamic stabilization underwent colonoscopy during the first 24 h of hospitalization and capsule enteroscopy when needed. Patients with massive ongoing bleeding underwent computed tomography angiography (CTA), and when active bleeding was detected embolization was immediately performed. Results The mean age of the patients was 70.2 ± 14.6 years and 271 (51.3%) of them were men. At least one comorbidity was present in 464 patients (87.9%), cardiovascular disease in 266 (50.4%), while 158 (30%) patients were on antiplatelet drugs and 96 (18.2%) on anticoagulants. The most common causes of bleeding were diverticulosis (19.7%) and ischemic colitis (19.3%). Thirty-six patients (6.9%) had small intestinal bleeding. In 117 patients (22.2%) active bleeding or recent bleeding stigmata were found and in 82 of them (92.1%) endoscopic hemostasis was applied. Embolization was performed in 10 (1.9%) and was successful in seven (70%) cases, while surgical hemostasis was required in only six (1.1%) cases. Forty-four (8.3%) patients had a rebleeding episode, and 13 patients died with an overall mortality of 2.5%. Conclusions Management of ALGIB based on an intensive protocol is safe and effective. The bleeding source can be identified in most cases with a favorable outcome.

Abstract
BACKGROUND Effective multidisciplinary management of gastrointestinal bleeding (GIB) requires effective communication. We instituted a protocol to standardize communication practices with the hypothesis that outcomes would improve following protocol initiation. METHODS We performed a retrospective cohort analysis of 442 patients who required procedural management of acute GIB at our institution during a 50-month period spanning 25 months before and 25 months after implementation of a multidisciplinary communication protocol. The protocol stipulates that when a patient with severe GIB is identified, a conference call is coordinated among the gastroenterology, interventional radiology, and acute care surgery teams. A consensus plan is generated and then reassessed following procedural interventions and changes in patients' status. Patients' characteristics, management strategies, and outcomes were compared before and after protocol initiation. RESULTS Patient populations before and after protocol initiation were similar in age, comorbidities, outpatient use of antiplatelet/anticoagulant medications, admission vital signs, and admission laboratory values. The median interval between admission and the first procedure was significantly shorter in the protocol group (40 vs 47 hours, p = 0.046). The proportion of patients who received packed red blood cell transfusions decreased following protocol initiation (41% vs 50%, p = 0.018). Median hospital length of stay was significantly shorter in the protocol group (5.0 vs 6.0 days, p = 0.014). Readmissions with GIB were decreased after protocol implementation (8% vs. 15%, p = 0.023). CONCLUSION Implementation of a multidisciplinary protocol for management of acute GIB was associated with earlier intervention, fewer packed red blood cell transfusions, shorter hospital length of stay, and fewer readmissions with GIB. Future research should seek to establish causal relationships between communication practices and outcomes. LEVEL OF EVIDENCE Therapeutic study, level III.

Abstract
BACKGROUND Acute lower gastrointestinal bleeding (LGIB) is a major cause of morbidity and mortality. Multidetector row computed tomography (CT) with gastrointestinal (GI) bleed protocol is a novel diagnostic technique for detecting and localizing LGIB. Being rapid and noninvasive, it may be useful as a first-line modality to investigate cases of acute LGIB. GOALS To assess and compare diagnostic accuracy of (99M)Technetium (Tc)-labeled red blood cell (RBC) scintigraphy and multidetector row CT with GI bleed protocol for detection and localization of source of acute LGIB. STUDY Requirement of informed consent was waived for this retrospective study. Seventy-six patients had undergone either RBC scintigraphy, CT with GI bleed protocol, or both, followed by conventional angiography for evaluation of acute persistent LGIB between January 2010 and February 2014 at our institution. Accuracy of both modalities was assessed using conventional angiography as reference standard and compared using the 2-tailed, Fisher exact test. A P-value of <0.05 was considered statistically significant. RESULTS Fifty-one, 20, and 5 patients had undergone RBC scintigraphy only, CT with GI bleed protocol only, and both modalities, respectively. Fourteen of 25 patients in the CT group had angiographic evidence of active bleeding as compared with 32 of 56 patients in the scintigraphy group. CT with GI bleed protocol had higher accuracy (96%) than (99M)Tc-labeled RBC scintigraphy (55.4%, P<0.001). CONCLUSIONS CT with GI bleed protocol was more accurate in detecting and localizing the source of acute LGIB as compared with (99M)Tc-labeled RBC scintigraphy.

Abstract
Ischemic colitis is the result of colonic hypoperfusion and is regarded as a relatively rare condition. It can be roughly classified as occlusive and non-occlusive. Pathogenesis includes a usually transient compromise in the colonic vasculature, with a parallel activation of an inflammatory cascade caused primarily by reperfusion. Diagnosis of ischemic colitis remains often difficult and requires a combination of diagnostic techniques, whereas clinical signs are occasionally only seen late as complications. Gold standard is considered to be colonoscopy. Clinical presentation and treatment of ischemic colitis vary widely depending on the degree of ischemia. Patients of intensive care unit (ICU) with ischemic colitis are often under-diagnosed, since the parallel co-morbidities and the nonspecific nature of symptoms that mimic almost any abdominal pathology, can mislead the doctor. Moreover, sedated or ventilated patients can mask many of the characteristic features of ischemic colitis and make the diagnosis challenging. Bedside colonoscopy and diagnostic laparoscopy in ICUs are two options, which seem lately to be reliable and promising in diagnosing ischemic colitis in critically ill patients.

Abstract
Lower GI bleeding is a common cause for hospitalization in adults. Medication-associated mucosal injury is an important clinical entity that can result in significant morbidity and mortality. We present the case of a 45-year-old woman with a 3-month history of intermittent abdominal cramping and rectal bleeding. Her medical history was extensive and included end-stage renal disease and a remote history of endometrial carcinoma that was treated with radiation. Initial workup was concerning for ischemic and radiation colitis, however, histology was most consistent with acute inflammation and ulceration associated with crystal fragments. Sevelamer and cholestyramine are commonly used ion-exchange resins that have been associated with mucosal damage. Both medications were discontinued and her symptoms resolved. Our case highlights an underrecognized but important cause of hematochezia.

Abstract
Bleeding per rectum is a relatively common acute surgical presentation. Common causes include diverticular disease, colitis, haemorrhoids, polyps, etc. An 83-year-old man with a history of recurrent rectosigmoid diverticulitis and bilateral internal iliac artery aneurysms for 2 years presented with rectal bleeding. He was suspected to have a diverticular bleed based on history and examination. A CT scan revealed a large haematoma adjacent to the right isolated internal iliac artery aneurysm (IIIAA) almost indistinguishable from the adjacent rectosigmoid, consistent with a ruptured IIIAA and an ileorectal fistula. The fistula was of a primary vascular enteric type and was accentuated by the inflammation arising from the diverticulitis. Hence, presence of more common or apparently obvious causes should not deter clinicians from thoroughly investigating the case. Rare causes should be kept in mind while dealing with common acute presentations, especially in elderly patients with multiple comorbidities.

Can the colour of per-rectal bleeding estimate the risk of lower gastrointestinal bleeding caused by malignant lesion? Int J Colorectal Dis 2016; 31:335-42.

Abstract
PURPOSE To estimate the risk of lower gastrointestinal bleeding (LGIB) caused by malignant lesion in patients presenting with per-rectal bleeding (PRB), by using visual aid as an objective measurement of PRB colour. METHODS This was a prospective observational study on patients presented with PRB to Family Medicine Specialty Clinic, who undergo flexible sigmoidoscopy (FS) or colonoscopy (CLN) from December 2012 to September 2013. Patients aged 40 years old or above, haemodynamically stable, with normal haemoglobin level were included. Patients with a history of previous colonic surgery, refused to have FS or CLN, with ophthalmologic diseases such as colour blindness were excluded. Parameters including subjective description of PRB colour, number of chosen red colour by patients, source and distance of bleeding from anal verge were recorded for analysis. Receiver operating characteristic (ROC) curve was used to identify the optimal cutoff level of colour for diagnosing colonic lesion. Diagnostic accuracy was assessed by area under the ROC curve (AUC). Accountability of this model was assessed by logistic regression. RESULTS The dark PRB colour was associated with diagnosis of tumour (p < 0.001) and advanced neoplastic polyp (p < 0.001). The light PRB colour was associated with the diagnosis of piles (p < 0.001). The performance of our model to predict tumour or advanced neoplastic polyps by colour (AUC, 0.798) had a better discriminative power than that to predict colonic lesion alone (AUC, 0.610) by ROC curve analysis. CONCLUSION Objective measurement of PRB colour accurately estimated the risk of LGIB caused by malignant lesion in patients presenting with PRB.

Abstract
PURPOSE Lower gastrointestinal (GI) bleeding is defined as bleeding distal to the ligament of Treitz. In the UK, it represents approximately 3 % of all surgical referrals to the hospital. This review aims to provide review of the current evidence regarding the management of this condition. METHODS Literature was searched using Medline, Pubmed, and Cochrane for relevant evidence by two researchers. This was conducted in a manner that enabled a narrative review of the evidence covering the aetiology, clinical assessment and management options of continuously bleeding patients. FINDINGS The majority of patients with acute lower GI bleeding can be treated conservatively. In cases where ongoing bleeding occurs, colonoscopy is still the first line of investigation and treatment. Failure of endoscopy and persistent instability warrant angiography, possibly preceded by CT angiography and proceeding to superselective embolisation. Failure of embolisation warrants surgical intervention. CONCLUSIONS There are still many unanswered questions. In particular, the development of a more reliable predictive tool for mortality, rebleeding and requirement for surgery needs to be the ultimate priority. There are a small number of encouraging developments on combination therapy with regard to angiography, endoscopy and surgery. Additionally, the increasing use of haemostatic agents provides an additional tool for the management of bleeding endoscopically in difficult situations.

Abstract
INTRODUCTION The association between thrombocytopenia (TP) and gastrointestinal hemorrhage was not completely understood. The purpose of this study is to evaluate the risk of gastrointestinal hemorrhage and post-hemorrhage mortality in patients with TP. METHODS Using the Taiwan National Health Insurance Research Database, we identified 1033 adults aged ≥18 years diagnosed with TP in 2000-2003. Non-TP cohort consisted of 10,330 adults randomly selected and matched by age and sex from the same dataset. Incident events of gastrointestinal hemorrhage occurring after TP from January 1, 2000, through December 31, 2008, were ascertained from medical claims. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of gastrointestinal hemorrhage associated with TP were calculated. Another nested cohort study consisted of 27,369 patients with hospitalization due to gastrointestinal hemorrhage between January 1, 2004, and December 31, 2010. We calculated the adjusted odds ratios (ORs) and 95% CIs of 30-day mortality after gastrointestinal hemorrhage in patients with and without TP during admission. RESULTS The incidences of gastrointestinal hemorrhage for people with and without TP were 14.5 and 5.07 per 1000 person-years, respectively (P<0.0001). Compared to people without TP, patients with TP had increased risk of gastrointestinal hemorrhage (HR, 2.61; 95% CI, 2.05-3.32). In the nested cohort study, TP was associated with post-hemorrhage mortality (OR, 1.98; 95% CI, 1.09-3.59). CONCLUSION Patients with TP showed higher risks of gastrointestinal hemorrhage and post-hemorrhage mortality. Our findings suggest the urgency of preventing and managing gastrointestinal hemorrhage by a multidisciplinary medical team for this specific population.

Abstract
Colonic diverticular disease is the most common cause of lower gastrointestinal bleeding. In the past, this condition was usually managed with urgent colectomy. Recently, the development of endoscopy and interventional radiology has led to a change in the management of colonic diverticular bleeding.The aim of this systematic review is to define the best treatment for colonic diverticular bleeding.A systematic bibliographic research was performed on the online databases for studies (randomized controlled trials [RCTs], observational trials, case series, and case reports) published between 2005 and 2014, concerning patients admitted with a diagnosis of diverticular bleeding according to the PRISMA methodology.The outcomes of interest were: diagnosis of diverticulosis as source of bleeding; incidence of self-limiting diverticular bleeding; management of non self-limiting bleeding (endoscopy, angiography, surgery); and recurrent diverticular bleeding.Fourteen studies were retrieved for analysis. No RCTs were found. Eleven non-randomized clinical controlled trials (NRCCTs) were included in this systematic review. In all studies, the definitive diagnosis of diverticular bleeding was always made by urgent colonoscopy. The colonic diverticular bleeding stopped spontaneously in over 80% of the patients, but a re-bleeding was not rare. Recently, interventional endoscopy and angiography became the first-line approach, thus relegating emergency colectomy to patients presenting with hemodynamic instability or as a second-line treatment after failure or complications of hemostasis with less invasive treatments.Colonoscopy is effective to diagnose diverticular bleeding. Nowadays, interventional endoscopy and angiographic treatment have gained a leading role and colectomy should only be entertained in case of failure of the former.

Abstract
OBJECTIVE In this article, we illustrate imaging findings of colorectal emergencies encountered in the acute setting that are primarily noninfectious and noninflammatory in origin. Our review should enable the reader to identify and understand common colorectal emergencies and related complications in clinical practice. CONCLUSION The diagnosis of colorectal emergencies is mostly straightforward, but it can be challenging because of the overlap of presenting symptoms and imaging findings. Therefore, it is essential to clarify the cause, narrow the differential diagnosis, and identify associated complications.

Abstract
BACKGROUND It is unclear whether there is a shared pathway in the development of diverticular disease (DD) and potentially neoplastic colorectal lesions since both diseases are found in similar age groups and populations. AIM To determine the association between DD and colorectal pre-neoplastic lesions in an African-American urban population. METHODS Data from 1986 patients who underwent colonoscopy at the Howard University Hospital from January 2012 through December 2012 were analyzed for this study. The presence of diverticula and polyps was recorded using colonoscopy reports. Polyps were further classified into adenoma or hyperplastic polyp based on histopathology reports. Multiple logistic regression was done to analyze the association between DD and colonic lesions. RESULTS Of the 1986 study subjects, 1,119 (56%) were females, 35% had DD and 56% had at least one polyp. There was a higher prevalence of polyps (70 vs. 49%; OR = 2.3; 95% CI: 1.9-2.8) and adenoma (43 vs. 25%; OR = 2.0; 95% CI: 1.7-2.5) in the diverticular vs. non-diverticula patients. Among patients who underwent screening colonoscopy, the presence of diverticulosis was associated with increased odds of associated polyps (OR = 9.9; 95% CI: 5.4-16.8) and adenoma (OR = 5.1; 95% CI: 3.4-7.8). CONCLUSION Patients with DD are more likely to harbor colorectal lesions. These findings call for more vigilance on the part of endoscopists during colonoscopy in patients known to harbor colonic diverticula.

Abstract
Diverticular hemorrhage is the most common reason for lower gastrointestinal bleeding (LGIB) with substantial cost of hospitalization and a median length of hospital stay of 3 days. Bleeding usually is self-limited in 70-80% of cases but early rebleeding is not an uncommon problem that can be reduced with proper endoscopic therapies. Colonoscopy is recommended as first-line diagnostic and therapeutic approach. In the vast majority of patients diverticular hemorrhage can be readily managed by interventional endotherapy including injection, heat cautery, clip placement, and ligation to achieve endoscopic hemostasis. This review will serve to highlight the various interventions available to endoscopists with specific emphasis on superior modalities in the endoscopic management of diverticular bleeding.

Abstract
BACKGROUND Diverticular bleeding is the most common cause of acute severe lower gastrointestinal bleeding. Diagnostic and therapeutic approaches have not been standardized. OBJECTIVE Development of an evidence-based management algorithm. MATERIALS AND METHODS A systematic search of the literature (PubMed 1998-2013) was carried out and a review with consideration of current guidelines is given. RESULTS The lifetime risk of clinically relevant bleeding is estimated to be 5 % in persons with colonic diverticula. Patients with clinically suspected diverticular hemorrhage should be admitted to hospital. Diverticular bleeding will cease spontaneously in around 70-90 % of the cases. In patients with severe lower gastrointestinal tract bleeding, defined as instability of the circulation, persistent bleeding after 24 h, drop of the hemoglobin level to ≥ 2 g/dl or the necessity for transfusion, endoscopy of the upper and lower gastrointestinal tract within the first 12-24 h is recommended. In patients with active diverticular bleeding or signs of recent hemorrhage (e.g. visible vessel or adherent clot) endoscopic therapy is strongly recommended because it significantly decreases the rate of early and late rebleeding. Angiography with superselective embolization is a therapeutic option in patients where endoscopy failed. Surgery should be considered in patients with ongoing bleeding and failure of interventional treatment and in patients who suffered from recurrent severe diverticular bleeding. CONCLUSIONS Diverticulosis coli remains the most common cause of lower gastrointestinal bleeding. Colonoscopy is recommended as first-line diagnostic and therapeutic approach. In the vast majority of patients diverticular hemorrhage can be readily managed either conventionally or by interventional therapy.

Abstract
BACKGROUND Surgical disease is inadequately addressed globally, and emergency conditions requiring surgery contribute substantially to the global disease burden. METHODS This was a review of studies that contributed to define the population-based health burden of emergency surgical conditions (excluding trauma and obstetrics) and the status of available capacity to address this burden. Further data were retrieved from the Global Burden of Disease Study 2010 and the University of Washington's Institute for Health Metrics and Evaluation online data. RESULTS In the index year of 2010, there were 896,000 deaths, 20 million years of life lost and 25 million disability-adjusted life-years from 11 emergency general surgical conditions reported individually in the Global Burden of Disease Study. The most common cause of death was complicated peptic ulcer disease, followed by aortic aneurysm, bowel obstruction, biliary disease, mesenteric ischaemia, peripheral vascular disease, abscess and soft tissue infections, and appendicitis. The mortality rate was higher in high-income countries (HICs) than in low- and middle-income countries (LMICs) (24.3 versus 10.6 deaths per 100,000 inhabitants respectively), primarily owing to a higher rate of vascular disease in HICs. However, because of the much larger population, 70 per cent of deaths occurred in LMICs. Deaths from vascular disease rose from 15 to 25 per cent of surgical emergency-related deaths in LMICs (from 1990 to 2010). Surgical capacity to address this burden is suboptimal in LMICs, with fewer than one operating theatre per 100,000 inhabitants in many LMICs, whereas some HICs have more than 14 per 100,000 inhabitants. CONCLUSION The global burden of surgical emergencies is described insufficiently. The bare estimates indicate a tremendous health burden. LMICs carry the majority of emergency conditions; in these countries the pattern of surgical disease is changing and capacity to deal with the problem is inadequate. The data presented in this study will be useful for both the surgical and public health communities to plan a more adequate response.
