Abstract
PURPOSE OF REVIEW Gastrointestinal (GI) bleeding can carry minimal or significant risk for recurrent hemorrhage. Timing of feeding after GI bleeding remains an area of debate, and here we review the evidence supporting recommendations. RECENT FINDINGS Improved understanding of the pathophysiology of GI bleeding and the evolution of treatment strategies has significantly altered the management of GI bleeding and the associated propensity for rebleeding. Early feeding following peptic ulcer bleeding remains ill-advised for high risk lesions while early initiation of liquid diets following cessation of esophageal variceal bleeding is appropriate and shortens hospital stays. Time to feeding following GI bleeding is inherently based on the disease etiology, severity, and risk of recurrent hemorrhage. With evolving standards of care, rates of rebleeding following endoscopic hemostasis are decreasing. Some evidence exists for early feeding however, larger multi-center trials are needed to help optimize timing of feeding in higher risk lesions.

Abstract
Acute upper gastrointestinal (GI) bleeding is a commonly encountered condition that can potentially be life-threatening. Endoscopy is the diagnostic modality of choice, but it is important to recognize it's shortcomings. We introduce a 61-year-old female who presented with hematemesis and syncope. She had a history of recurrent episodes of hematemesis and hospitalizations for the preceding 18 months, for which multiple endoscopies had been performed but had failed to demonstrate a source. A repeat esophagogastroduodenoscopy (EGD) performed at our facility was unremarkable. A CT scan demonstrated a lobulated mass-like filling defect in the gastric cardia consistent with solitary varix with an abnormal fold pattern. An upper GI follow-through series was performed to better characterize this varix. The patient subsequently underwent balloon-occluded retrograde transvenous obliteration with successful control of the source of bleeding. It is important to keep in mind that EGD while being the gold standard for the diagnosis of varices, has its limitations, and should be augmented with the use of non-traditional diagnostic modalities such as CT scans or radionuclide imaging.

Abstract
Whether to provide artificial enteral nutrition therapy to a patient with evidence of gastrointestinal bleeding (GIB) creates a difficult clinical dilemma. Concern that enteral feeding may contribute to the morbidity associated with GIB leads to delays in initiating enteral therapy or to cessation of feeding in the patient in whom artificial nutrition support has already been started. Surprisingly, evidence of GIB is not an automatic contraindication to further enteral feeding. Depending on the etiology of the GIB, enteral nutrition may protect the gut mucosa and reduce further bleeding in some patients, actually increase risk for rebleeding in other patients, or serve as a moot point with no relation to further bleeding or morbidity in still other patients. In many cases, an endoscopic evaluation is needed to distinguish the differential etiology of the GIB. The nutrition support specialist needs a full understanding of the physiology behind the varying diagnoses for GIB to know whether feedings can be initiated or continued or whether enteral feedings need to be withheld for 48-72 hours until risk for rebleeding and further morbidity is minimized.

Abstract
OBJECTIVE This study aimed to identify the risk factors associated with rebleeding and long-term outcomes after capsule endoscopy (CE) for obscure gastrointestinal bleeding (OGIB) in a follow-up study. METHODS Data of consecutive patients who underwent CE due to OGIB from June 2002 to January 2012 were retrospectively reviewed. The Cox proportional hazard model was used to evaluate the risk factors associated with rebleeding, while Kaplan-Meier survival curves and the log-rank test were used to analyze cumulative rebleeding rates. RESULTS The overall rebleeding rate after CE in patients with OGIB was 28.6% (97/339) during a median follow-up of 48 months (range 12-112 months). Multivariate analysis showed that age ≥60 years (hazard ratio [HR] 2.473, 95% confidence interval [CI] 1.576-3.881, P = 0.000), positive CE findings (HR 3.393, 95% CI 1.931-5.963, P = 0.000), hemoglobin ≤70 g/L before CE (HR 2.010, 95% CI 1.261-3.206, P = 0.003), nonspecific treatments (HR 2.500, 95% CI 1.625-3.848, P = 0.000) and the use of anticoagulants, antiplatelet or non-steroidal anti-inflammatory drugs after CE (HR 2.851, 95% CI 1.433-5.674, P = 0.003) were independent risk factors associated with rebleeding. Univariate analysis showed that chronic hepatitis was independently associated with rebleeding in CE-negative patients (P = 0.021). CONCLUSIONS CE has a significant impact on the long-term outcome of patients with OGIB. Further investigation and close follow-up in patients with OGIB and those with negative CE findings are necessary.

Abstract
Obscure gastrointestinal bleeding is still a clinical challenge for gastroenterologists. The recent development of novel technologies for the diagnosis and treatment of different bleeding causes has allowed a better management of patients, but it also determines the need of a deeper comprehension of pathophysiology and the analysis of local expertise in order to develop a rational management algorithm. Obscure gastrointestinal bleeding can be divided in occult, when a positive occult blood fecal test is the main manifestation, and overt, when external sings of bleeding are visible. In this paper we are going to focus on overt gastrointestinal bleeding, describing the physiopathology of the most usual causes, analyzing the diagnostic procedures available, from the most classical to the novel ones, and establishing a standard algorithm which can be adapted depending on the local expertise or availability. Finally, we will review the main therapeutic options for this complex and not so uncommon clinical problem.

Abstract
This guideline presents recommendations for the step-wise management of patients with overt upper gastrointestinal bleeding. Hemodynamic status is first assessed, and resuscitation initiated as needed. Patients are risk-stratified based on features such as hemodynamic status, comorbidities, age, and laboratory tests. Pre-endoscopic erythromycin is considered to increase diagnostic yield at first endoscopy. Pre-endoscopic proton pump inhibitor (PPI) may be considered to decrease the need for endoscopic therapy but does not improve clinical outcomes. Upper endoscopy is generally performed within 24h. The endoscopic features of ulcers direct further management. Patients with active bleeding or non-bleeding visible vessels receive endoscopic therapy (e.g., bipolar electrocoagulation, heater probe, sclerosant, clips) and those with an adherent clot may receive endoscopic therapy; these patients then receive intravenous PPI with a bolus followed by continuous infusion. Patients with flat spots or clean-based ulcers do not require endoscopic therapy or intensive PPI therapy. Recurrent bleeding after endoscopic therapy is treated with a second endoscopic treatment; if bleeding persists or recurs, treatment with surgery or interventional radiology is undertaken. Prevention of recurrent bleeding is based on the etiology of the bleeding ulcer. H. pylori is eradicated and after cure is documented anti-ulcer therapy is generally not given. Nonsteroidal anti-inflammatory drugs (NSAIDs) are stopped; if they must be resumed low-dose COX-2-selective NSAID plus PPI is used. Patients with established cardiovascular disease who require aspirin should start PPI and generally re-institute aspirin soon after bleeding ceases (within 7 days and ideally 1-3 days). Patients with idiopathic ulcers receive long-term anti-ulcer therapy.

Abstract
Upper gastrointestinal (UGI) bleeding secondary to ulcer disease occurs commonly and results in significant patient morbidity and medical expense. After initial resuscitation, carefully performed endoscopy provides an accurate diagnosis of the source of the UGI hemorrhage and can reliably identify those high-risk subgroups that may benefit most from endoscopic hemostasis. Large-channel therapeutic endoscopes are recommended. Endoscopists should be very experienced in management of patients with UGI hemorrhage, including the use of various hemostatic devices. For patients with major stigmata of ulcer hemorrhage--active arterial bleeding, nonbleeding visible vessel, and adherent clot--combination therapy with epinephrine injection and either thermal coaptive coagulation (with multipolar or heater probe) or endoclips is recommended. High-dose intravenous proton-pump inhibitors are recommended as concomitant therapy with endoscopic hemostasis of major stigmata. Patients with minor stigmata or clean-based ulcers will not benefit from endoscopic therapy and should be triaged to less intensive care and be considered for early discharge. Effective endoscopic hemostasis of ulcer bleeding can significantly improve outcomes by reducing rebleeding, transfusion requirement, and need for surgery, as well as reduce cost of medical care.

Abstract
This prospective, cohort study assessed the independent predictors of in-hospital mortality in patients with acute upper gastrointestinal haemorrhage admitted to the medical intensive care unit (MICU) at the University Clinical Centre Maribor, Slovenia. Using univariate, multivariate and logistic regression methods the predictors of mortality in 54 upper gastrointestinal haemorrhage patients (47 men, mean ± SD age 61.6 ± 14.2 years) were investigated. The mean ± SD duration of treatment in the MICU was 2.8 ± 2.9 days and the mortality rate was 31.5%. Significant differences between non-survivors and survivors were observed in haemorrhagic shock, heart failure, infection, diastolic blood pressure at admission, haemoglobin and red blood cell count at admission, and lowest haemoglobin and red blood cell count during treatment. Heart failure (odds ratio 59.13) was the most significant independent predictor of in-hospital mortality. Haemorrhagic shock and the lowest red blood cell count during treatment were also important independent predictive factors of in-hospital mortality.

Abstract
Upper gastrointestinal bleeding from peptic ulcer disease is a common clinical event, resulting in considerable patient morbidity and significant health care costs. Inhibiting gastric acid secretion is a key component in improving clinical outcomes, including reducing rebleeding, transfusion requirements, and surgery. Raising intragastric pH promotes clot stability and reduces the influences of gastric acid and pepsin. Patients with high-risk stigmata for ulcer bleeding (arterial bleeding, nonbleeding visible vessels, and adherent clots) benefit significantly from and should receive high-dose intravenous proton pump inhibitors (PPIs) after successful endoscopic hemostasis. For patients with low-risk stigmata (flat spots or clean ulcer base), oral PPI therapy alone is sufficient. For oozing bleeding (an intermediate risk finding), successful endoscopic hemostasis and oral PPI are recommended. Using intravenous PPIs before endoscopy appears to reduce the frequency of finding high-risk stigmata on later endoscopy, but has not been shown to improve clinical outcomes. High-dose oral PPIs may be as effective as intravenous infusion in achieving positive clinical outcomes, but this has not been documented by randomized studies and its cost-effectiveness is unclear.

Abstract
Upper gastrointestinal bleeding secondary to ulcer disease is common and results in substantial patient morbidity and medical expense. After initial resuscitation to stabilize the patient, carefully performed endoscopy provides an accurate diagnosis and identifies high-risk ulcer patients who are likely to rebleed with medical therapy alone and will benefit most from endoscopic hemostasis. For patients with major stigmata of ulcer hemorrhage--active arterial bleeding, nonbleeding visible vessel, and adherent clot--combination therapy with epinephrine injection and either thermal coagulation (multipolar or heater probe) or endoclips is recommended. High-dose intravenous proton pump inhibitors are recommended as concomitant therapy after successful endoscopic hemostasis. Patients with minor stigmata or clean-based ulcers will not benefit from endoscopic treatment and should receive high-dose oral proton pump inhibitor therapy. Effective medical and endoscopic management of ulcer hemorrhage can significantly improve outcomes and decrease the cost of medical care by reducing rebleeding, transfusion requirements, and the need for surgery.

Abstract
Obscure gastrointestinal bleeding (OGIB) is defined as an intermittent or continuous loss of blood in which the source has not been identified after upper endoscopy and colonoscopy. It constitutes a diagnostic and therapeutic challenge for the general internist and the gastroenterologist. This article provides an overview of the etiology, clinical presentation, and diagnostic modalities of OGIB including push enteroscopy, double balloon enteroscopy, wireless capsule endoscopy, enteroclysis, angiography, bleeding scanning with labeled red blood cells, and surgery with intraoperative enteroscopy. Therapeutic modalities including iron replacement, combined hormones, octreotide acetate, therapeutic endoscopy, and surgery are also discussed. In addition, a rational approach to patients with OGIB according to the clinical presentation is presented herein.

Abstract
Aspirin and nonsteroidal anti-inflammatory drug (NSAID)-induced gastrointestinal bleeding is recognized as an important health problem. We performed a single-center randomized clinical trial to compare the effect of high-dose intravenous proton pump inhibitor (omeprazole) alone (group 1) with omeprazole in combination with a low-dose prostaglandin analog (misoprostol; group 2) on clinical outcomes in patients with aspirin/NSAID-induced upper gastrointestinal bleeding. Additionally, we evaluated the contribution of Helicobacter pylori eradication therapy on the late consequences. Patients were recruited to the study if they had upper gastrointestinal bleeding with history of taking aspirin or other NSAIDs within the week before the onset of bleeding. All were evaluated in terms of probable risk factors. After the standard treatment protocol, patients with histologically proven H pylori infection were prescribed a triple eradication therapy for 14 days. The primary end points were recurrent bleeding, surgery requirement, and death rates before discharge and at the end of follow-up period. This study lasted for 2 years. A total of 249 patients with upper gastrointestinal bleeding were admitted, and 49.7% of these patients were users of aspirin/NSAIDs. There were 67 patients in group 1 and 56 in group 2. The distributions for gender, age, comorbidity, H pylori infection, and high-risk ulcer rate were similar in both groups. Among aspirin/NSAID users, endoscopy revealed duodenal ulcer in 47 (38.2%), gastric ulcer in 10 (8.1%), and erosive gastropathy in 33 (26.8%). The overall rebleeding occurred in 12.2%, death in 2.4% of the patients. The in-hospital death (P=.414), rebleeding (P=.925), and surgery (P=.547) rates were similar in both treatment groups. After the follow-up period of 3 months, overall rebleeding occurred in 4.1%, and death in 4.8% of the patients. The overall mortality rate was highest in those >65 years old, who were chronic low-dose aspirin users with comorbidity. One died of transfusion-related graft-versus-host disease. In this pilot study, we indicated that adding misoprostol (600 microg/day) to standardized proton pump inhibitor treatment did not improve or change the rebleeding or mortality rates of patients with upper gastrointestinal bleeding related to aspirin/NSAID use. Other prospective studies on higher doses of misoprostol are needed to establish the coeffect. One should bear in mind that all blood products must be irradiated before transfused to the host.

Abstract
PURPOSE OF REVIEW This review provides an update on the management of upper gastrointestinal bleeding with special attention to patient preparation, sedation, hemostatic techniques, and postprocedure care. RECENT FINDINGS In a large multicenter clinical trial, nurse-administered propofol sedation had a complication rate of less than 0.2%. The optimal management for an ulcer with adherent clot was confirmed by a meta-analysis to be clot removal and endoscopic treatment of the underlying lesion. A number of prospective studies have demonstrated that capsule endoscopy is the most sensitive imaging modality for identifying lesions in the small bowel and that double-balloon enteroscopy is the least invasive modality available for the management of these lesions. SUMMARY This update describes many recent advances in the diagnosis and management of upper gastrointestinal bleeding. However, clearly, much work needs to be done in this field. Since propofol is not available for use in all endoscopy units, is there a better alternative for deep sedation? Rebleeding occurs in 20% of patients after endoscopic therapy, and so can we provide better outcomes with newer technologies (endoscopic suturing devices)? Finally, what is the best management for Helicobacter pylori-negative, nonsteroidal antiinflammatory drug-negative ulcer patients?

Dig Dis Sci 2005; 50:2063-70.

Abstract
Our purpose was to analyze risks versus benefits of nasogastric (NG) intubation for gastrointestinal (GI) bleeding performed soon after myocardial infarction (MI). While NG intubation and aspiration is relatively safe, clinically beneficial, and routinely performed in the general population for recent GI bleeding, its safety after MI is unstudied and unknown. In addition to the usual complications of NG tubes, patients status post-MI may be particularly susceptible to myocardial ischemia or cardiac arrhythmias from anxiety or discomfort during intubation. We studied NG intubation within 30 days of MI in 125 patients at two hospitals from 1986 through 2001. Indications for NG intubation included melena in 55 patients; fecal occult blood with an acute hematocrit decline, severe anemia, or sudden hypotension in 37; hematemesis in 18; bright red blood per rectum in 8; and dark red blood per rectum in 7. The intubation was performed on average 5.3 +/- 7.2 (SD) days after MI. NG aspiration revealed bright red blood in 38 patients, "coffee grounds"-appearing blood in 45, and clear (or bilious) fluid in 42. Among 114 of the patients undergoing esophagogastroduodenoscopy (EGD), EGD revealed the cause of bleeding in 79 (95%) of 83 patients with a grossly bloody NG aspirate versus 12 (39%) of 31 patients with a clear aspirate (P < 0.0001, OR = 31.3, OR CI = 9.4-103.1). Among 85 patients undergoing EGD within 16 hr of NG intubation, stigmata of recent hemorrhage were present in 28 (42%) of 66 with a bloody NG aspirate versus 3 (16%) of 19 with a clear aspirate (P = 0.06, OR = 3.93). Among 35 patients undergoing lower GI endoscopy, lower endoscopy revealed the cause of bleeding in 14 (56%) of 25 patients with a clear NG aspirate versus 1 (10%) of 10 patients with a grossly bloody aspirate (P < 0.04, OR = 11.46, OR CI = 1.55-78.3). The two NG tube complications (epistaxis during intubation and gastric erosions from NG suctioning) were neither cardiac nor major (requiring blood transfusions). This study suggests that short-term NG intubation is relatively safe and may be beneficial and indicated for acute GI bleeding after recent MI. Aside from improving visualization at EGD, the potential benefits include providing a rational basis for the timing of endoscopy (urgent versus semielective), for prioritizing the order of endoscopy (EGD versus colonoscopy), and for avoiding or deferring endoscopy in low-yield situations (e.g., colonoscopy when the NG aspirate is bloody). These benefits may be particularly relevant in patients after recent MI due to their increased endoscopic risks.

PURPOSE Gastrointestinal hemorrhage is a common clinical problem, which accounts for approximately 1 to 2 percent of acute hospital admissions. The colon is responsible for approximately 87 to 95 percent of all cases of lower gastrointestinal bleeding, with the remaining cases arising in the small bowel. The etiology, diagnostic evaluation, management, and treatment options available for lower gastrointestinal hemorrhage were reviewed. METHODS A review of lower gastrointestinal bleeding was performed, which discussed the most common etiologies with a few rare and unusual causes. The current literature about different diagnostic techniques, management problems, and therapeutic options was reviewed. Current management strategies and treatment options for the many causes of lower gastrointestinal bleeding will be reviewed. RESULTS A review of the different causes of lower gastrointestinal hemorrhage and available diagnostic studies was performed. Management strategies based on the etiology of the bleeding and results of the diagnostic studies were discussed. An algorithm was provided to develop a diagnostic and therapeutic treatment strategy for lower gastrointestinal hemorrhage. CONCLUSIONS Lower gastrointestinal hemorrhage can be a difficult and frustrating problem to both the clinician and the patient. Knowledge of the available diagnostic tests to help identify the source of bleeding is essential to the practicing clinician. Once the source is identified, management strategies and available treatment options need to be specific for each individual case. This review will aid the practicing physician in developing an algorithm for lower gastrointestinal hemorrhage.

Abstract
The repair of peripheral nerves with sutures is time consuming. The aim of this study was to evaluate the benefits and functional outcome of repairing nerves with octyl 2-cyanoacrylate adhesive. The right peroneal nerve of 64 male, Lewis rats was sectioned and repaired. The rats were randomized into 3 experimental groups: A (n = 27), using only octyl 2-cyanoacrylate; B (n = 27), using 4, 10-0 nylon sutures; and C (n = 10), a sham operation. The recovery of nerve function was quantified through walking-track analyses; group A showed faster return of nerve function than B, especially at 15 days (P < 0.017). Histologic analysis showed a greater axonal regeneration in group A versus group B and no indication of tissue toxicity in group A. No dehiscence occurred during the 6-month study. Use of adhesive shortened the anastomosis time from 12 minutes to 4 minutes. These results indicate that the use of octyl 2-cyanoacrylate adhesive for nerve anastomoses is safe and effective and may have benefits compared with the use of sutures.

Abstract
GERD is ubiquitous throughout the adult population in the United States. It commonly adversely affects quality of life and occasionally causes life-threatening complications. The new and emerging medical and endoscopic therapies for GERD and the new management strategies for BE should dramatically reduce the clinical toll of this disease on society.

Abstract
The management of patients with small bowel bleeding remains a diagnostic and therapeutic challenge. In most gastrointestinal bleeding episodes, the source of hemorrhage is localized to either the upper gastrointestinal tract or colon; however, in about 5% of cases, upper endoscopy and colonoscopy are nondiagnostic, and the small intestine is the site of bleeding. Patients with suspected small bowel source of bleeding may present with either occult blood loss or recurrent overt gastrointestinal hemorrhage requiring frequent blood transfusions and hospitalizations. Knowing the etiology and site of hemorrhage is essential prior to initiating appropriate therapy. The most common causes of small bowel bleeding are vascular ectasia, tumors, ulcerative diseases, and Meckel's diverticula. For patients with severe obscure bleeding, push enteroscopy with a 220- to 250-cm enteroscope is strongly recommended. This procedure provides not only a thorough examination for diagnosis, but also allows for biopsy, tattooing, and hemostasis of lesions. If enteroscopy is nondiagnostic, capsule endoscopy is recommended. A diagnostic capsule endoscopy will direct appropriate medical, endoscopic, or surgical intervention, depending on whether the lesion is single or multiple, and whether the patient is a surgical candidate for intraoperative enteroscopy. Intraoperative enteroscopy should be strongly considered in patients with recurrent bleeding and a nondiagnostic evaluation. Laparoscopy and intraoperative enteroscopy is highly recommended in young patients (< 50 years of age) because there is an increased frequency of small bowel tumors and Meckel's diverticulum which are amenable to surgical therapy.

Abstract
BACKGROUND The purpose of this study was to evaluate the impact of the global diagnostic approach on the outcome of patients suspected of having acute (a) gastrointestinal (GI) graft-versus-host disease (GVHD). METHODS Ten consecutive patients with suspected aGI-GVHD were prospectively explored with an exhaustive approach including video-capsule endoscopy (VCE). Images observed with VCE were compared with results obtained with other GI investigations including duodenal biopsies. RESULTS.: Five patients had a normal VCE examination: four were successfully treated symptomatically, but one died as a result of toxoplasmosis. VCE disclosed aGI-GVHD lesions in all five remaining patients, and two of the five were considered normal by upper GI endoscopy. All of these patients experienced improvement in their GI symptoms within 2 weeks of adjustments to their immunosuppressive treatment. CONCLUSIONS This approach has enhanced the authors' ability to adapt immunosuppressive treatments in patients suffering from suspected aGI-GVHD. Further investigation of the apparently high negative predictive value of VCE will be of great interest, particularly with a view to avoiding unnecessary immunosuppressive treatment.

Abstract
PURPOSE OF REVIEW This review discusses key issues in the management of upper gastrointestinal bleeding including patient preparation, sedation, hemostatic techniques, disposition, and recommended pharmacologic interventions. RECENT FINDINGS Optimal resuscitation before endoscopy and proper pharmacologic interventions after endoscopy seem to be as crucial to the management of patients with upper gastrointestinal bleeding as meticulous hemostatic techniques during the procedure. In a retrospective evaluation of patients with upper gastrointestinal bleeding, multivariate analysis demonstrated significantly reduced morbidity and mortality in those who underwent aggressive preendoscopic resuscitation. In a prospective, randomized clinical trial, patients who received intravenous proton pump inhibitor therapy after endoscopic intervention had a significantly reduced rebleeding rate compared with their placebo control group. SUMMARY The algorithms described in this review can be applied clinically today and should directly lead to improved outcome. Nevertheless, even with the latest care available, results are not optimal. This review points to two major areas where we can benefit from improvement: primary hemostasis and recurrent bleeding. By pointing to these limitations, it is hoped that this review can help stimulate research in the field by applying new technologies to solve these problems. Endoscopic ultrasound, for example, could be used to help identify feeding vessels that can be treated endoscopically, thus potentially decreasing the incidence of failed primary hemostasis. Endoscopic suturing, when more fully developed, may provide a better hemostatic technique that can reduce the incidence of recurrent bleeding. It is only through these reviews that our state of knowledge in the field can be constantly reevaluated to update today's clinician with the latest knowledge and stimulate tomorrow's researchers with challenging problems.

Abstract
Gastrointestinal endoscopy is the primary diagnostic and therapeutic modality in the management of gastrointestinal bleeding. Esophagogastroduodenoscopy, small bowel enteroscopy, and colonoscopy are well-established standards for initial evaluation of gastrointestinal bleeding, and have been used effectively for diagnosis, prognosis, and therapy. Although thermal, injection, and mechanical methods have been the mainstay of endoscopic therapy, promising new technologies such as endoscopic ultrasound and wireless capsule endoscopy will further advance our ability to improve morbidity and mortality from severe gastrointestinal hemorrhage. Herein we review current standards and recent advances in the endoscopic management of upper, lower, and obscure gastrointestinal bleeding.

Abstract
PURPOSE OF REVIEW This review provides an updated summary of gastric interventional endoscopy. Relevant original articles and topic reviews are highlighted in the areas of infection control, light sedation, hemostasis, endoscopic mucosal resection, and endoscopic placement of enteric devices. RECENT FINDINGS Several key findings are worth noting: the increased use of propofol by nonanesthesiologists for deep sedation with minimal adverse side effects, the adaptation of tissue adhesive agents for the treatment of bleeding gastric varices, the successful treatment of early gastric cancer by endoscopic mucosal resection, and the development of direct percutaneous endoscopic jejunostomy tubes for patients at high risk of aspiration. SUMMARY These recent developments in the field of interventional endoscopy have already made a great impact on clinical care. More advanced procedures can be performed safely while the patient is under deep sedation. Yet, these developments have not slowed down the need for improvement in interventional endoscopy. Researchers continue to look for smaller instruments, better optics, and more advanced accessories. This constant state of flux marks the field of interventional endoscopy and ensures its progress.
