Yu Q, Funaki B, Ahmed O. Twenty years of embolization for acute lower gastrointestinal bleeding: a meta-analysis of rebleeding and ischaemia rates. Br J Radiol 2024; 97:920-932. [PMID: 38364312 DOI: 10.1093/bjr/tqae037] [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: 10/18/2022] [Revised: 11/24/2023] [Accepted: 02/07/2024] [Indexed: 02/18/2024] Open
Abstract
BACKGROUND Transarterial embolization (TAE) for acute lower gastrointestinal bleeding (LGIB) can be technically challenging due to the compromise between achieving haemostasis and causing tissue ischaemia. The goal of the present study is to determine its technical success, rebleeding, and post-embolization ischaemia rates through meta-analysis of published literature in the last twenty years. METHODS PubMed, Embase, and Cochrane Library databases were queried. Technical success, rebleeding, and ischaemia rates were extracted. Baseline characteristics such as author, publication year, region, study design, embolization material, percentage of superselective embolization were retrieved. Subgroup analysis was performed based on publication time and embolization agent. RESULTS A total of 66 studies including 2121 patients who underwent embolization for acute LGIB were included. Endoscopic management was attempted in 34.5%. The pooled overall technical success, rebleeding, post-embolization ischaemia rates were 97.0%, 20.7%, and 7.5%, respectively. Studies published after 2010 showed higher technical success rates (97.8% vs 95.2%), lower rebleeding rates (18.6% vs 23.4%), and lower ischaemia rates (7.3% vs 9.7%). Compared to microcoils, NBCA was associated with a lower rebleeding rate (9.3% vs 20.8%) at the expense of a higher post-embolization ischaemia rate (9.7% vs 4.0%). Coagulopathy (P = .034), inotropic use (P = .040), and malignancy (P = .002) were predictors of post-embolization rebleeding. Haemorrhagic shock (P < .001), inotropic use (P = .026), malignancy (P < .001), coagulopathy (P = .002), blood transfusion (P < .001), and enteritis (P = .023) were predictors of mortality. Empiric embolization achieved a similarly durable haemostasis rate compared to targeted embolization (23.6% vs 21.1%) but a higher risk of post-embolization ischaemia (14.3% vs 4.7%). CONCLUSION For LGIB, TAE has a favourable technical success rate and low risk of post-embolization ischaemia. Its safety and efficacy profile has increased over the last decade. Compared to microcoils, NBCA seemed to offer a more durable haemostasis rate at the expense of higher ischaemia risk. Due to the heterogeneity of currently available evidence, future prospective and comparative studies are warranted. ADVANCES IN KNOWLEDGE (1) Acute LGIB embolization demonstrate a high technical success rate with acceptable rate of rebleeding and symptomatic ischaemia rates. Most ischaemic stigmata discovered during routine post-embolization colonoscopy were minor. (2) Although NBCA seemed to offer a more durable haemostasis rate, it was also associated with a higher risk of ischaemia compared to microcoils. (3) Coagulopathy, malignant aetiology, and inotropic use were predictors of rebleeding and mortality. (4) Routine post-embolization endoscopy to assess for ischaemia is not indicated.

Abstract
Colonic diverticular bleeding (CDB) is the most frequent cause of acute lower gastrointestinal bleeding. The aim of this study was to evaluate the efficacy and safety of transcatheter arterial embolization (TAE) for CDB as first-line treatment with extravasation on contrast-enhanced computed tomography (CECT), compared with endoscopic hemostasis. Three Japanese institutions participated in this retrospective cohort study. Data from consecutive patients admitted with a diagnosis of CDB with extravasation on CECT were reviewed. One hospital performed TAE and the others conducted urgent colonoscopy (CS) as the first-line treatment for CDB with extravasation on CECT. The primary outcome was rebleeding rate within 30 days after first-line treatment. In total, 165 CDB cases with extravasation on CECT (TAE group, n = 39; CS group, n = 126) were analyzed in this study. The rebleeding rate within 30 days was significantly lower in the TAE group (7.69%) than in the CS group (23.02%; P = .038). The bleeding point detection rate was significantly higher in the TAE group (89.74%, 35/39) than in the CS group (37.30%, 47/126; P < .0001). Even in those cases in which a bleeding point was detected, the rebleeding rate was significantly lower in the TAE group (0%) than in the endoscopic hemostasis-success group (23.91%; P = .005). No severe complications of Grade 3 or more were seen with TAE. We showed that TAE is an effective, safe hemostatic method, and a useful alternative to endoscopic hemostasis for first-line treatment of CDB.

Abstract
BACKGROUND Postoperative anastomotic bleeding is considered a rare but life-threatening complication. There is no standard treatment strategy for this emergency condition. The aim of this study was to report our experiences in the management of postoperative anastomotic bleeding in patients with colorectal cancer. METHODS We analyzed the general characteristics, treatments, and outcomes of patients with anastomotic bleeding after surgery for colorectal carcinoma at the Sixth Affiliated Hospital of Sun Yat-Sen University between July 2013 and September 2019 retrospectively. A univariate and multivariate analysis was performed to find protective factors for endoscopic hemostasis. Risk factors for anastomotic leakage after colonoscopy were also analyzed. RESULTS A total of 9870 patients underwent surgeries for colorectal carcinoma between July 2013 and September 2019. Colonoscopies were performed in 78 cases with postoperative anastomotic bleeding. The effective rate of initial endoscopic hemostasis was 81% (63/78). In univariate and multivariate analysis, hemoclip therapy (odds ratio = 4.572; 95%CI 1.305-16.017; P = 0.017) and postoperative anastomotic bleeding within 5 days (odds ratio = 3.639; 95%CI 1.045-12.675; P = 0.042) are protective factors for endoscopic hemostasis. Comorbidity was associated with an increased risk for anastomotic leakage. CONCLUSIONS Colonoscopy seems to be an effective way to achieve hemostasis for patients with anastomotic bleeding after surgery for colorectal carcinoma. It may be more effective in the early postoperative period, and hemoclip appears to be the first choice to control postoperative anastomotic bleeding.

Abstract
PURPOSE Laparoscopic rectosigmoid resection is the standard surgical treatment for recurrent sigmoid diverticulitis. However, speaking of mesenterium division, no unique standard procedure is actually provided. Surgeons can perform it at the level of either the sigmoid vessels or the inferior mesenteric vessels. The objective of this study was to compare intra- and postoperative complications of both techniques. METHODS From a prospective collected database of patients that underwent elective laparoscopic sigmoid resection between January 2004 and December 2014, a retrospective analysis according to the selected operative technique was performed. RESULTS A total of 1016 patients were operated, and a pedicle division of the mesenteric vessels was performed in 280 patients (central group 27.6%) while a peripheral division was performed in 736 patients (peripheral group 72.4%). Comparison of these two groups demonstrated no statistically significant difference regarding age or stage of disease. Thirteen patients (1.3%) developed anastomotic leak; among them, nine belonged to the peripheral group (1.2 vs 1.4% p = 0.794). Twenty-four patients (2.4%) developed postoperative rectal bleeding but only in nine cases was a bleeding of the anastomosis confirmed using endoscopy (seven peripheral group vs two central group, 0.95 vs 0.7% p = 0.712). Moreover, postoperative morbidity did not significantly differ between the two groups. A very low mortality rate was observed, with 2 deaths (both in the peripheral group). CONCLUSIONS Ligation of inferior mesenteric vessels does not seem to affect anastomotic healing; both surgical techniques presented similar incidence of anastomotic bleeding. In this analysis, we could not identify any significant difference in overall morbidity and mortality.

Abstract
Aneurysms of the abdominal visceral arteries are infrequently encountered. Jejunal artery aneurysm (JAA) is one of the rarest visceral aneurysms, especially in young patients. Endovascular surgery tends to be an effective treatment for visceral artery aneurysms. Here, we report a case of symptomatic JAA with a peripheral dilated vessel in a young patient. However, in consideration of the patient's anatomic suitability and young age, we chose open surgical intervention with intraoperative angiography. Thus, we could resect the aneurysm and the peripheral dilated vessel, preserve the bowel, and leave no devices that could cause further complication. The choice of the most appropriate treatment should depend on aneurysm characteristics and the background of the patient.

Abstract
AIM The aim of this study was to assess the safety and efficacy of the emborrhoid technique (embolization of the superior haemorrhoidal arteries) in patients ineligible for surgery. METHODS Between January 2014 and April 2015, 30 consecutive patients (average age 58 years) suffering from disabling chronic bleeding due to haemorrhoidal disease and with a contraindication for surgery (n = 23) or with a failure of instrumental or surgical treatment (n = 7) underwent embolization. All cases were discussed at multidisciplinary meetings including a proctology specialist or a surgeon and an interventional radiologist. We performed super selective micro coil embolization (pushable 2-3 mm fibre coils) of the distal branches of the superior rectal arteries with a microcatheter, via a right femoral approach, under local anaesthesia. We assessed clinical outcome by evaluating bleeding and specific clinical scores relating to bleeding and changes in quality of life. RESULTS Immediate technical success, with no complication, was achieved in 93% of cases. A mean of 3.1 arteries per patient was embolized, with a mean of 7.6 coils per patient. Median follow-up was 5 months. Clinical score improvement was observed in 72%, in 17 patients after a single embolization session, and in four additional patients after a second embolization session. No improvement in bleeding was observed in eight patients (28%). CONCLUSION Distal coil embolization of the superior rectal arteries for disabling chronic bleeding due to haemorrhoidal disease is safe and effective in patients untreatable by surgery.

Abstract
PURPOSE The purpose of this study was to comprehensively evaluate the short-term outcomes after percutaneous embolization of the superior rectal artery (SRA) with metallic coils and particles for the management of hemorrhoids. MATERIALS AND METHODS Forty patients (15 men, 25 women) with a mean age of 35±5 years (SD) (range: 25-65 years) were prospectively enrolled. All patients had symptomatic hemorrhoids. The distribution of internal hemorrhoids was as follows: grade I (n=6, 16%); grade II (n=28, 69%) and grade III (n=6; 15%). All patients had percutaneous embolization of the SRA with metallic coils and synthetic polyvinyl alcohol particles. Follow-up evaluation included clinical examination, rectoscopy, histopathological analysis of rectal mucosa, duplex Doppler blood flow quantification, electromyography, sphincterometry of the anal sphincter and analysis of patient satisfaction. RESULTS No immediate complications were observed and no patients had anal pain syndrome after embolization. Hemorrhoids showed a 43% size reduction after embolization (P<0.05). Taking into account the symptom resolutions such as irritation, discomfort, bloody discharge and pain, satisfaction was observed in 5/6 (83%) patients with grade III hemorrhoids and 32/34 patients (94%) with grades I-II hemorrhoids. One month after embolization, anal sphincter contractility normalized and no changes in anal electromyography were observed. Blood flow in the hemorrhoidal plexus dropped from 109±1.2ml/min/100g (SD) before treatment to 60.2±4.4ml/min/100g (SD) (P<0.05) the day after embolization and remained unchanged one month after embolization. CONCLUSION Our study demonstrates that embolization of SRA with particle and coils does not lead to ischemia in patients with symptomatic hemorrhoids. Short-term results with regard to symptom management for hemorrhoidal disease are very encouraging and should stimulate further prospective and multicenter studies.

Abstract
PURPOSE To retrospectively evaluate the safety and risk of transcatheter arterial embolization (TAE) with N-butyl cyanoacrylate (NBCA) for urgent acute arterial bleeding control in the lower gastrointestinal tract by angiography and colonoscopy. MATERIALS AND METHODS NBCA TAE was performed in 16 patients (mean age, 63.7 y) with lower gastrointestinal bleeding (diverticular hemorrhage, tumor bleeding, and intestinal tuberculosis). Angiographic evaluation was performed by counting the vasa recta filled with casts of NBCA and ethiodized oil (Lipiodol) after TAE. Patients were classified as follows: group Ia, with a single vas rectum with embolization of 1 branch (n = 6); group Ib, with a single vas rectum with embolization of ≥ 2 branches (n = 8); group II, with embolization of multiple vasa recta (n = 2). All patients underwent colonoscopy within 1 month, and ischemic complications (ulcer, scar, mucosal swelling, fibrinopurulent debris, and necrosis) were evaluated. RESULTS The procedure was successful in all patients. No ischemic change was observed in any patients in group Ia and in two patients in group Ib. Ischemic changes were observed in six group Ib patients and both group II patients. Group Ib patients experienced ischemic complications that improved without treatment. One patient in group II underwent resection for intestinal perforation after embolization of three vasa recta. One patient in group II with sigmoid stricture with embolization of six vasa recta required prolonged hospitalization. CONCLUSIONS NBCA embolization of ≥ 3 vasa recta can induce ischemic bowel damage requiring treatment. NBCA TAE of one vas rectum with ≥ 2 branches could also induce ischemic complications. However, these were silent and self-limited.

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
BACKGROUND Anastomotic bleeding is an infrequent but life-threatening complication after stapled digestive tract anastomosis. Endovascular embolization is one of the available treatments, but precise clinical outcomes are yet to be evaluated. PURPOSE To evaluate the efficacy and safety of endovascular embolization for managing anastomotic bleeding after stapled digestive tract anastomosis. MATERIAL AND METHODS Twenty-eight patients were diagnosed with anastomotic bleeding after stapled digestive tract anastomosis by digital subtraction angiography (DSA). Curative effect was summed for analysis. RESULTS All bleeding arteries were located in the stoma and were identified by contrast agent spillover by DSA. The offending arteries were superselectively catheterized and embolized with microcoils and/or gelatin sponge particles. Laboratory examinations showed normal hemoglobin and red blood cell counts when the patients' abdominal cavity drainage tubes stopped draining blood. The follow-up period was 3.2-84.7 months (median, 19.7 months). Four patients died during this time, of which two had cholangiocarcinoma, one had gastric cancer with tumor recurrence and multiple organ failure, and the final patient had a subarachnoid hemorrhage 4 months after embolization. In the surviving patients, no rebleeding occurred after embolization and no additional intervention or surgery was required. CONCLUSION Endovascular embolization is safe and effective for managing anastomotic bleeding after stapled digestive tract anastomosis.

Abstract
OBJECTIVE To determine the long-term results of patients undergoing transcatheter coil embolization for the treatment of acute colonic haemorrhage. METHODS Patients undergoing angiography for suspected colonic bleeding between January 2002 and December 2012 were reviewed (average age, 60 years; 38.4% male). Baseline, procedural and outcome parameters were recorded following the Society of Interventional Radiology guidelines. Primary outcome measures included early (<30 days) and delayed (>30 days) rebleeding events and adverse procedure-related complication. Average follow-up time was 996 days (median, 232 days; range, 30-3663 days). RESULTS One or multiple sites of bleeding were identified in 40 cases. Coil embolization was performed in 39 patients, 26 (66.7%, 26/39) of whom were treated successfully without technical/clinical failure (n = 12) or loss to follow-up (n = 1). Three patients (11.5%, 3/26) rebled in the early period within 30 days; one patient went on to hemicolectomy. Four patients (15.3%, 4/26) experienced delayed rebleeding after 30 days; two of whom also underwent hemicolectomy. No major complication occurred. One minor complication of short segment arterial dissection was seen in the clinical failure group. One case of asymptomatic ischaemia was identified on a patient undergoing pre-operative colonoscopy for elective bowel resection. No instances of ischaemic stricture were seen. All-cause mortality of successfully treated and all patients at 1 year was 31% (8/26) and 30% (12/40), respectively. CONCLUSION Transcatheter coil embolization is a durable treatment option with a technical and clinical success rate of 67% in the setting of acute colonic haemorrhage. A modest level of rebleeding was seen among successfully treated patients in both the early and delayed periods; in the majority of patients, embolization proved to be definitive therapy. ADVANCES IN KNOWLEDGE Transcatheter coil embolization is a durable and potentially definitive therapy in the management of acute colonic haemorrhage.

Abstract
Jejunal artery aneurysms are rare, with only six cases reported in the literature to date. Endovascular embolisation of the jejunal artery is rarely performed. Herein, we report the case of a 57-year-old man who successfully underwent endovascular embolisation for bleeding caecal diverticulosis, during which a 9-mm fusiform jejunal artery aneurysm was incidentally diagnosed. Subsequently, the jejunal aneurysm was successfully embolised using Vortex coils.

Abstract
PURPOSE The 'emborrhoid' technique consists of the embolization of the hemorrhoidal arteries. The endovascular arterial occlusion is performed using coils placed in the terminal branches of the superior rectal arteries. The emborrhoid technique has been modeled after elective transanal Doppler-guided hemorrhoidal artery ligation which has been shown to be effective in hemorrhoidal disease. We report the first 14 cases of our experience with emborrhoid technique. MATERIALS AND METHODS Fourteen patients with disabling chronic rectal bleeding were treated using the emborrhoid technique (3 women, 11 men). The stage of the hemorrhoidal disease was II (10 patients), III (3), and IV (1). This treatment was decided by a multidisciplinary team (proctologist, visceral surgeon, and radiologist). Seven patients underwent previous proctological surgery. Ten patients had coagulation disorders (anticoagulants or cirrhosis). Superior rectal arteries were embolized with pushable microcoils (0.018). RESULTS Technical success of the embolization procedure was 100 %. Clinical success at 1 month was 72 % (10/14). Of the 4 patients who experienced rebleeding, two underwent additional embolization of the posterior rectal arteries with success. No pain or ischemic complications were observed in 13 patients. One patient experienced a temporary painful and edematous, perianal reaction. CONCLUSION Our case studies suggest that coil embolization of the superior rectal arteries is technically feasible, safe and well tolerated. Additional studies are needed to evaluate the efficacy of this new 'emborrhoid' technique in the management of hemorrhoidal disease.

Abstract
BACKGROUND Therapeutic angioembolization is a relatively new "rescue treatment" modality for gastrointestinal hemorrhage (GIH) for unstable patients who fail primary treatment approaches; however, the effectiveness of this treatment and the incidence of ischemic necrosis following embolization for acute GIH are poorly described. The purpose of this study was to evaluate the effectiveness and safety of "rescue" transcatheter superselective angioembolization (SSAE) for the treatment of hemodynamically unstable patients with GIH. METHODS A 10-year retrospective review of all hemodynamically unstable patients (systolic blood pressure < 90 mm Hg and ongoing transfusion requirement) who underwent "rescue" SSAE for GIH after failed endoscopic management was performed. All patients with evidence of active contrast extravasation were included. Data were collected on demographics, comorbidities, clinical presentation, and type of intravascular angioembolic agent used. Outcomes included technical success (cessation of extravasation), clinical success (no rebleeding requiring intervention within 30 days), and incidence of ischemic complications. RESULTS Ninety-eight patients underwent SSAE for GIH during the study period; 47 were excluded owing to lack of active contrast extravasation. Of the remaining 51 patients, 22 (43%) presented with a lower GIH and 29 (57%) with upper GIH. The majority underwent embolization with a permanent agent (71%), while the remaining patients received either a temporary agent (16%) or a combination (14%). The overall technical and clinical success rates were 98% and 71%, respectively. Of the 14 patients with technical success but clinical failure (rebleeding within 30 days) and the 1 patient with technical failure, 4 were managed successfully with reembolization, while 2 underwent successful endoscopic therapy, and 9 had surgical resections. Only one patient had an ischemic complication (small bowel necrosis) requiring resection. CONCLUSION SSAE, with reembolization if necessary, is an effective rescue treatment modality for hemodynamically unstable patients with active GIH. Of the patients, 20% will fail SSAE and require additional intervention. Ischemic complications are extremely rare. LEVEL OF EVIDENCE Therapeutic study, level IV.

Abstract
Gastrointestinal (GI) bleeding from the colon is a common reason for hospitalization and is becoming more common in the elderly. While most cases will cease spontaneously, patients with ongoing bleeding or major stigmata of hemorrhage require urgent diagnosis and intervention to achieve definitive hemostasis. Colonoscopy is the primary modality for establishing a diagnosis, risk stratification, and treating some of the most common causes of colonic bleeding, including diverticular hemorrhage which is the etiology in 30% of cases. Other interventions, including angiography and surgery, are usually reserved for instances of bleeding that cannot be stabilized or allow for adequate bowel preparation for colonoscopy. We discuss the colonoscopic diagnosis, risk stratification, and definitive treatment of colonic hemorrhage in patients presenting with severe hematochezia.

Abstract
PURPOSE To assess the safety and efficacy of transcatheter arterial embolization for lower gastrointestinal bleeding (LGIB) and to determine the prognostic factors that affect clinical outcome. MATERIALS AND METHODS All patients diagnosed with LGIB by angiography at a single institution from April 2006 to January 2013 were included in a retrospective study. The rates of technical success, early recurrent bleeding, major complications, clinical success, and in-hospital mortality for transcatheter arterial embolization were determined. The influence of possible prognostic factors on the outcome was analyzed. RESULTS A total of 112 patients were included (36 with small-bowel LGIB, 36 with colon LGIB, and 40 with rectal LGIB). N-butyl cyanoacrylate (NBCA) was the embolic agent for 84 patients (75.0%), whereas gelatin sponge pledgets (n = 20), microcoils (n = 2), polyvinyl alcohol particles with adjunctive gelatin sponge pledgets (n = 1), and blood clots (n = 1) were used in the other patients. The technical success rate was 96.4%. For the entire group, the rates of early recurrent bleeding, major complications, clinical success, and in-hospital mortality were 17.4%, 4.6%, 74.5%, and 25.0%, respectively. These were 15.2%, 4.8%, 75.3%, and 26.2%, respectively, in the NBCA group. Hematologic malignancy, immobilization status, and coagulopathy were significant prognostic factors for clinical outcomes. CONCLUSIONS Transcatheter arterial embolization is a safe and effective treatment for LGIB. NBCA could be used as a primary embolic agent for this procedure.

Abstract
BACKGROUND Lower gastrointestinal bleeding represents 20 % of all gastrointestinal bleedings. Interventional radiology has transformed the treatment of this pathology, but the long-term outcome after selective embolization has been poorly evaluated. The aim of this study is thus to evaluate the short-term and long-term outcomes after selective embolization for colonic bleeding. METHODS From November 1998 to December 2010, all acute colonic embolizations for hemorrhage were retrospectively reviewed and analyzed. The risk factors for post-embolization ischemia were also assessed. RESULTS Twenty-four patients underwent colonic embolization. There were 6 men and 18 women with a median age of 80 years (range, 42-94 years). The underlying etiologies included diverticular disease (41.9 %), post-polypectomy bleeding (16.7 %), malignancy (8.2 %), hemorrhoid (4.1 %), and angiodysplasia (4.1 %). In 23 patients, bleeding stopped (95.8 %) after selective embolization. One patient presented a recurrence of bleeding with hemorrhagic shock and required urgent hemorrhoidal ligature. Four patients required an emergent surgical procedure because of an ischemic event (16.7 %). One patient died of ileal ischemia (mortality, 4.1 %). The level of embolization and the length of hypoperfused colon after embolization were the only risk factors for emergent operation. Mean hospital stay was 18 days (range, 9-44 days). After a mean follow-up of 28.6 months (range, 4-108 months), no other ischemic events occurred. CONCLUSION In our series, selective transarterial embolization for acute colonic bleeding was clinically effective with a 21 % risk of bowel ischemia. The level of embolization and the length of the hypoperfused colon after embolization should be taken into consideration for emergent operation.

Abstract
Acute lower gastrointestinal bleeding (LGIB) is a frequent gastrointestinal cause of hospitalization, particularly in the elderly, and its incidence appears to be on the rise. Endoscopic and radiographic measures are available for the evaluation and treatment of LGIB including flexible sigmoidoscopy, colonoscopy, angiography, radionuclide scintigraphy and multi-detector row computed tomography. Although no modality has emerged as the gold standard in the management of LGIB, colonoscopy is the current preferred initial test for the majority of the patients presenting with hematochezia felt to be from a colon source. Colonoscopy has the ability to diagnose all sources of bleeding from the colon and, unlike the radiologic modalities, does not require active bleeding at the time of the examination. In addition, therapeutic interventions such as cautery and endoclips can be applied to achieve hemostasis and prevent recurrent bleeding. Studies suggest that colonoscopy, particularly when performed early in the hospitalization, can decrease hospital length of stay, rebleeding and the need for surgery. However, results from available small trials are conflicting and larger, multicenter studies are needed. Compared to other management options, colonoscopy is a safe procedure with complications reported in less than 2% of patients, including those undergoing urgent examinations. The requirement of bowel preparation (typically 4 or more liters of polyethylene glycol), the logistical complexity of coordinating after-hours colonoscopy, and the low prevalence of stigmata of hemorrhage complicate the use of colonoscopy for LGIB, particularly in urgent situations. This review discusses the above advantages and disadvantages of colonoscopy in the management of acute lower gastrointestinal bleeding in further detail.

Abstract
Radiological techniques are important in evaluating patients with gastrointestinal bleeding. Scintigraphic, computed tomographic angiographic, and enterographic techniques are sensitive tools in identifying the source of bleeding and may be useful in identifying patients likely to have a benign course and in selecting patients for therapeutic intervention. Angiography plays a key role in bleeding localization, and modern embolization techniques make this a viable therapeutic option. With the refining developments in body imaging and related reconstructive techniques, it is likely that radiological interventions will play an expanding and critical role in evaluating patients with gastrointestinal hemorrhage in the future.

Abstract
There are multiple strategies for evaluating and treating lower intestinal bleeding (LIB). Colonoscopy has become the preferred initial test for most patients with LIB because of its diagnostic and therapeutic capabilities and its safety. However, few studies have directly compared colonoscopy with other techniques and there are controversies regarding the optimal timing of colonoscopy, the importance of colon preparation, the prevalence of stigmata of hemorrhage, and the efficacy of endoscopic hemostasis. Angiography, radionuclide scintigraphy, and multidetector computed tomography scanning are complementary modalities, but the requirement of active bleeding at the time of the examination limits their routine use. In addition, angiography can result in serious complications. This review summarizes the available evidence regarding colonoscopy and radiographic studies in the management of acute LIB.

Abstract
PURPOSE To report initial experience using N-butyl cyanoacrylate (n-BCA) to control lower gastrointestinal hemorrhage (LGIH). MATERIALS AND METHODS From May 2005 to March 2009, 14 patients with LGIH underwent mesenteric angiography and transcatheter arterial embolization using n-BCA. Candidacy was primarily based on the patient's hemodynamic stability and the risk for future LGIH, determined by the presence of at least one of the following risk factors: more than one arterial feeder supplying the bleeding vessel, underlying coagulopathy, or need to resume anticoagulation after embolization. Outcome measures included technical success (immediate postembolic hemostasis confirmed with completion angiography showing no further extravasation of contrast medium), clinical success (postembolic hemostasis in the absence of complications 30 days after the procedure), and clinical failure (recurrence of LGIH necessitating repeat embolization or surgical treatment). RESULTS Fourteen patients with active LGIH were treated with n-BCA, with 100% technical success. Two patients had rebleeds resulting in bowel resection. One patient experienced a minor rebleed that spontaneously resolved. One patient died secondary to multiorgan failure in the setting of multiple medical problems. The remaining 10 patients had complete clinical success, experiencing no signs of rebleeding or infarction. CONCLUSIONS The results suggest that n-BCA can be a useful alternative embolic agent for the treatment of hemodynamically unstable patients with LGIH when standard microcoiling techniques fail or are not feasible and in patients with coagulopathy.

Abstract
INTRODUCTION Superselective mesenteric embolization is effective in arresting colonic diverticular hemorrhage with minimal complications, but long-term results are lacking. We aimed to review the short- and long-term outcome of superselective embolization in arresting colonic diverticular hemorrhage in an Asian population. METHODS A retrospective review of all patients who underwent superselective embolization for bleeding colonic diverticula from December 2000 to March 2009 was performed. These cases were drawn from a database of embolization for active gastrointestinal hemorrhage. Short-term outcomes (< or =30 days from procedure) identified included rebleeding, ischemia, or any further intervention for any of these two complications. Readmission for rebleeding and/or definitive surgery after 30 days (long-term outcome) was also documented. RESULTS Twenty-three patients, median age 65 years (range 41-79 years), formed the study group. Nineteen (82.6%) patients had active hemorrhage from right colonic diverticula while four (17.4%) had left-sided diverticular bleeding. Technical success was achieved in all 23 (100%) patients. SHORT-TERM OUTCOME: Five (21.7%) patients rebled within the same admission, and all underwent surgery. One patient perished from ensuing anastomotic dehiscence and septic shock and accounted for the only mortality (4.3%) in our series. There was no patient with ischemic complications. Another two (8.7%) patients underwent elective surgical resection on the advice of their surgeons in the absence of rebleeding. LONG-TERM OUTCOME: The median follow-up was 40 months (5-99 months). Of the remaining 16 (69.6%) patients for whom the procedure was definitive initially, four (25.0%) rebled within 2 years from the primary procedure, and elective surgery was performed in one of them. Another had repeat embolization, while the other two were successfully managed conservatively. These three patients refused surgical intervention. One patient was lost to follow-up, and the remaining 11 patients had no further complications. CONCLUSION Superselective embolization for active colonic diverticular hemorrhage is safe and effective and should be considered as a first line treatment if possible and available. The procedure could act as a bridge to a subsequent more definitive elective surgery or be definitive as seen in over 50% of our patients over a period of 40 months.

Abstract
BACKGROUND This study was performed to elucidate the etiology, effectiveness of diagnostic and therapeutic modalities, and outcomes in patients with acute lower gastrointestinal bleeding. METHODS A retrospective review of the medical records of 1,112 consecutive patients admitted to the surgical service of a single urban emergency hospital with lower gastrointestinal bleeding from 1988 to 2006. Two groups were compared: 1988-1997 and 1998-2006. RESULTS All patients underwent colonoscopy, 33.2% within 24 h of admission. Hematochezia was the most frequent presentation (55.5%), followed by maroon stool (16.7%) and melena (11.0%). Most patients, 690 (62.1%) also had upper endoscopy. Sixty-six patients subsequently had barium enemas. Eleven of 27 nuclide scans were positive. Arteriography was performed on 22 patients, with 11 positive results and 2 therapeutic. No statistical difference was found in procedures performed in our 2 time periods. Diverticulosis (33.5%), hemorrhoids (22.5%), and carcinoma (12.7%) were the most common etiologies with the diagnosis of diverticulosis more common in the 1998-2006 time period. The small bowel was the source in 14 total patients. Spontaneous cessation of the bleeding occurred in 863 (77.6%) patients. Endoscopic control increased from 1% in 1997-1998 to 4.4% in 1998-2006 (P < .05) with a corresponding decrease in the need for operative control from 22.6% to 16.6% in this same time period (P < .05). Furthermore, among elective operations, there was a decrease in right hemicolectomies from 31.6% of total elective cases to 13.9% (P < .05). Emergent operations were needed in 3.4% and 4.8% of patients. The readmission rate did not change over time and was 5.2% overall with >50% because of diverticular bleeding. CONCLUSION In this urban setting, diverticulosis, hemorrhoids, and carcinoma were the most common causes of severe acute lower gastrointestinal bleeding (LGIB) with diverticular bleed causing the highest recurrence. Colonoscopy allows for diagnosis in most patients with severe acute LGIB requiring hospitalization. Furthermore, it is now being used more effectively for hemostasis resulting in less operative intervention to control bleeding.

Abstract
INTRODUCTION Superselective embolization of visceral arterial branches has become integral in the management of acute lower gastrointestinal (GI) hemorrhage. The present study aimed to evaluate the success of superselective embolization as a primary therapeutic modality in the control of lower GI hemorrhage and to identify factors associated with rebleeding and surgical intervention after the procedure. METHODS We performed a retrospective review of all cases of superselective embolization for acute lower GI bleeding during a 7-year period (December 2000-October 2007) in a single 1,300-bed hospital in Singapore. Hemostasis was achieved with microcoils, polyvinyl alcohol particles, gelfoam, or by selective vasopressin infusion. Various clinical and hematologic factors were analyzed against rebleeding and surgical intervention after the procedure. RESULTS A total of 265 patients underwent mesenteric angiography for GI hemorrhage. Superselective embolization of visceral vessels for lower GI hemorrhage was performed in 32 patients (12%) whose median age was 66 years (range: 34-82 years). The group was of similar gender distribution, and the median follow-up was 8 months (range: 1-32 months). Location was the small bowel in 19% and the colon in 81%. The underlying etiologies included diverticular disease (59%), angiodysplasia (19%), ulcers (19%), and malignancy (3%). In 31 patients (97%) technical success was achieved, with immediate cessation of hemorrhage in every case. Clinical success was achieved in 20 patients (63%), all of whom were discharged well with no further intervention. Seven patients rebled, and 9 underwent surgery: 1 for incomplete hemostasis, 4 for rebleeding, 1 for infarcted bowel postembolization, and 3 on the basis of the surgeon's decision. There were 2 anastomotic leaks; 1 after surgery for postembolization ischemia and 1 after surgery for rebleeding. Overall mortality in this series was 9%. Rebleeding was more likely to occur if the site of bleeding was located in the small bowel compared to the colon (OR: 8.33, 95% CI 1.03-66.67). It was also more likely in patients with a hematocrit level </=20.0% (OR: 7.52, 95% CI: 1.14-50.00) and a platelets level </=140 x 10(9)/l (OR: 9.35, 95% CI: 1.36-62.5) just before the procedure. Surgical resection was also more likely in patients with a hematocrit level </=20.0% just before embolization (OR: 12.66, 95% CI: 1.96-83.33), and it appeared to be more likely if the underlying cause was diverticular disease (OR 8.70, 95% CI: 0.93-83.33). CONCLUSIONS The use of superselective mesenteric embolization for the treatment of lower GI bleeding is highly successful and relatively safe-97% technical success and 3% postembolization ischemia in our series. In 63% of cases it is definitive without any further intervention. Postembolization ischemia and surgery may be associated with a higher risk of anastomotic leak. Greater vigilance must be adopted in treating patients who have active hemorrhage from the small bowel and in those with a hematocrit </=20.0%.

Abstract
BACKGROUND Although limited haematochezia with the first bowel movement is frequent in patients undergoing colorectal resection, postoperative life-threatening lower gastrointestinal bleeding is very rare. The purpose of this study was to review our results in the management of this complication. METHODS We analysed the cases of patients with severe lower gastrointestinal bleeding after colorectal surgery from 2000 to 2006 in our hospital. We studied the general characteristics, diagnostic data, therapeutic management and outcome. We also reviewed the published articles regarding this issue. RESULTS This complication appeared in 7 (0.5%) of 1,389 colorectal procedures in the study period. In all the patients the anastomosis was stapled. In six of the seven patients bleeding resolved with conservative treatment including endoscopy. However, one patient required surgical treatment. There was no mortality and there were no anastomotic leaks in these seven patients. CONCLUSION Severe lower gastrointestinal bleeding after colorectal resection and stapled anastomosis is a rare complication. Only in unstable patients or failure of conservative measures is surgery indicated.

Abstract
UNLABELLED Transarterial catheter embolization (TAE) is integral in the management of lower gastrointestinal bleeding (BLGIT). The efficacy of superselective embolization has reduced the need for emergent surgical resection as a treatment modality. OBJECTIVE To determine the outcomes of TAE in the management of BLGIT in terms of efficacy rates, recurrent bleeding rates and long term results without the need for surgical intervention. METHOD Patients who underwent TAE for BLGIT between September 2000 and May 2006 were analysed. Data were extracted from the records for analysis. RESULTS Sixty-eight patients with a mean age of 76 years and equal gender distribution were analysed. Sixty-nine per cent presented with haematochezia, 40% with malena. Sixty-three patients had a prior RBC scan performed, all of which were positive. Colonoscopy was attempted in 18 patients of which four managed to localize the bleeding site. Embolization was performed in these patients using mainly polyvinyl alcohol particles and/or microcoils. The morbidity rate was 21%, comprising mainly fever and nonspecific abdominal pain with only four ischaemic complications and one report of colonic infarction. Early recurrent bleeding occurred in six patients. Three were treated with repeat embolization and two required surgery. There were no mortalities. After a mean follow-up of 12 months, 12 (17.6%) patients developed further episodes of BLGIT, necessitating further intervention. CONCLUSION Transarterial catheter embolization is effective and safe in the acute management of BLGIT and reduces the need for further definitive surgery in a majority of patients.

Abstract
Lower gastrointestinal hemorrhage is a common reason for hospital admission. Spontaneous cessation occurs in the majority of these patients; however, continued major bleeding is a difficult clinical problem. Emergency surgery, without prior knowledge of the bleeding site is associated with high morbidity and mortality rates. Accurate localization is therefore desirable. The authors present a review of current radiological imaging modalities and therapeutic options available to the clinician. They also provide a management algorithm to aid in the strategic management of this group of patients.

Experimental study on acute ischemic small bowel changes induced by superselective embolization of superior mesenteric artery branches with N-butyl cyanoacrylate. J Vasc Interv Radiol 2008; 19:755-63.

Abstract
PURPOSE To evaluate the degree of ischemic changes of the small bowel after superselective embolization of superior mesenteric artery (SMA) branches at the vasa recta level with N-butyl cyanoacrylate (NBCA) in dogs. MATERIALS AND METHODS In six dogs, superselective embolization was performed with NBCA in five isolated branches of the SMA at the vasa recta level. All dogs were sacrificed 24 hours after embolization. According to the extent of the NBCA mixtures on radiographs of the specimen, embolized segments were divided into group A (embolization of three or fewer vasa recta) or group B (embolization of four or more vasa recta). Histologic evaluation of the mucosal, submucosal, and muscle layers of the embolized segments was performed by a pathologist. RESULTS In group A (n=15), histologic findings were normal in seven segments (47%). Mild ischemic changes were noted in the mucosal layer in eight segments, the submucosal layer in four segments, and the muscle layer in one segment. In group B (n=15), ischemic changes were noted in the mucosal layer in all 15 segments, the submucosal layer in 14 segments, and the muscle layer in 10 segments. The difference in ischemic damage between groups A and B was statistically significant. CONCLUSIONS Superselective embolization involving three or fewer vasa recta of the SMA was relatively tolerable, and embolization involving four or more vasa recta carried an increased risk of substantial ischemic bowel damage. Further studies are necessary to determine the clinical implications of our findings in human subjects.

Abstract
PURPOSE This study was designed to identify the short-term safety and efficacy of super-selective embolization for lower gastrointestinal bleeding and to examine the long-term durability. METHODS Outcomes of patients who underwent super-selective embolization for lower gastrointestinal bleeding from January 1999 to September 2005 were identified retrospectively at a single institution. RESULTS Seventy-five hospitalizations (71 patients) were identified. Mean age was 73 years. Short-term outcomes: this technique was successful in achieving immediate hemostasis in 73 of 75 cases identified (97 percent). Twelve patients (16 percent) rebled, eight required surgery, and four were successfully reembolized. Five patients (7 percent) developed postembolization ischemia: four required operations, and one was followed clinically. Long-term outcomes: 52 patients were followed for a mean of 32 months. Eight patients were readmitted for recurrent bleeding: four required surgeries, one was successfully reembolized, and the remaining three patients were followed clinically. CONCLUSIONS This large series reaffirms the high success rate (97 percent) and relatively low acute ischemia risk (7 percent) of super-selective embolization for lower gastrointestinal bleeding. Furthermore, only 15 percent of patients ultimately required readmission for recurrent bleeding. It is our recommendation that super-selective embolization be used as the primary therapeutic modality in the treatment of angiogram positive lower gastrointestinal bleeding.

Abstract
Hemorrhoids usually do not pose diagnostic difficulties and they rarely cause massive bleeding. We report a case of massive rectal bleeding over 18 h needing 22 U blood transfusion treated by superselective transcatheter coil embolization 12 h following operative treatment performed in a different hospital. Diagnostic angiography with a view to superselective embolization, following failure of sigmoidoscopy to localize and treat the cause of hemorrhage, might act as a life-saving treatment in massive rectal bleeding, obviating the need for repeated endoscopy or emergency surgery.

Abstract
PURPOSE OF REVIEW Evaluation of the abdomen in critically ill patients can be challenging. This article reviews the available data and proposes evidence-based guidelines for evaluation of the abdomen in the critically ill patient. RECENT FINDINGS The critically ill are often clinically unevaluable due to distracting injuries, respiratory failure, obtundation, or other conditions. Even when patients can be examined, the clinical exam can be unreliable and misleading. Critically ill patients who are sufficiently stable to undergo imaging benefit from computerized tomography unless biliary sepsis is suspected, when ultrasound is preferred. There is an important role for endoscopy and angiography in the setting of gastrointestinal hemorrhage, as well as magnetic resonance imaging for mesenteric ischemia. Critically ill patients who are too unstable for imaging may require bedside laparoscopy or diagnostic peritoneal lavage. Abdominal compartment syndrome should be considered in the differential diagnosis of the unstable critically ill patient. Empiric laparotomy may still need to be employed in diagnosis and management of unstable patients. SUMMARY Timely and accurate diagnosis of life-threatening intraabdominal pathology is essential to care for critically ill patients. A multitude of laboratory, radiologic, and interventional modalities are available to evaluate the abdomen in the critically ill.

Abstract
Diagnostic angiography still plays an essential role in the diagnosis of patients,particularly those with acute lower GI bleeding. Transcatheter therapy appears to be a viable treatment alternative in selected patients with GI bleeding. Many interventionists today believe embolotherapy to be more effective initially and to have better long-term results, specifically less rebleeding, than vasopressin infusion with at least equal complication rates. Unfortunately, direct comparison of the two techniques in a randomized, controlled fashion has not been performed. Small patient series, such as those summarized here, suggest that the results of the two techniques are essentially equal, and ischemic complications appear more prevalent with embolotherapy. The use of embolotherapy--either empirically based on endoscopic or surgical findings or directed against a site found to have contrast extravasation-represents the current intervention of choice in the case of upper GI bleeding refractory to endoscopic intervention. Head-to-head studies directly comparing the efficacy, morbidity, and mortality associated with endovascular or surgical correction of bleeding from the upper GI tract is needed. Although the current tide favors embolotherapy in the lower GI tract, infusion of vasoconstricting agents deserves more attention. To that end, there is a great need for scientific data regarding the safety and efficacy of transcatheter therapy for upper and lower GI bleeding.
