  • DR RAVI GUPTACONSULTATNT G I ENDOSCOPIST LILAVATI HOSPITAL
  • UPPER G I ENDOSCOPY FOREIGN BODIES IN UPPER G I TRACT UPPER G I BLEED
  • Acute Upper GI bleed The annual rate of hospitalization for acute UGIB in the United States is 160 hospital admissions per 100,000 population, which translates into more than 400,000 per year In most settings, the vast majority of acute episodes of upper gastrointestinal bleeding (80 to 90%) have non- variceal causes, with gastroduodenal peptic ulcer accounting for the majority of lesions Mortality associated with peptic ulcer bleeding remains high at 5 to 10% N Engl J Med 2008;359:928-37.
  • F B IN UPPER G I TRACT F B IN ESOPHAGUS SHARP FBS WITH RISK OF PERFORATION
  • Indian scenarioLimited studies on the prevalence of peptic ulcer bleeding in IndiaPeptic ulcer is widely prevalent in India, more common among the population of South India than North IndiaConflicting data exist from different studies on the MC type of presentationLifetime prevalence of PU in India Delhi – 0.61% Chandigarh – 0.69 Chennai – 0.75%These studies have limitations in diagnostic method and not considering asymptomatic population Khuroo et al Gut 1989;30;930-934

  • Overall management ABC’s and adequate resuscitation   Early risk stratification  pre-endoscopy  at early endoscopyVery Low risk patients All other patients discharge home  admit High-risk patients Low-risk patients  Endoscopic hemostasis  Initiate daily dose PPI  Initiate high-dose IV PPI  Consider secondary prophylaxis  H pylori testing and treating  NSAID/COX2 use  ASA use
  • ROLE OF PRIMARY PHYSICIAN ADULT AGE GROUP ALCOHOL INTOXICATION X RAY NECK CHEST & ABDOMEN PLEASE DO NOT TRY ANY BANANA DIET ETC IF FB IN THE ESOPHAGUS OR IF SHARP FB, IT DELAYS ENDOSCOPIC INTEVENTION.
  • So what to do?- subgroup selection  Efficacy at best marginal, so PPI should NOT replace the role of adequate resuscitation and early endoscopy  Can provide PPI before endoscopy or not; more likely to be cost-effective IF:  Delay to endoscopy (over 16 hours)  Patient more likely to be bleeding from  a non variceal source  high-risk lesion (hematemesis, bloody NGT)  If you are going to use, high-dose preferred Barkun AN, GI Endosc 2008
  • F B ESOPHAGUS PAEDIATRIC AGE GROUP ADMISSION, DONE UNDER G A WITH TRACHEAL INTUBATION. SHARP OBJECTS USE OVERTUBE OR UMBRELLA ADULTS SUSPECT A STRICTURE BELOW THE FB
  • UPPER G I BLEED VARICEAL NON VARICEAL
  • What about an elevated INR andendoscopy? A presenting INR >1.5 does not predict rebleeding, yet is an independent predictor of subsequent death following an admission due to NVUGIB Correction of INR to 1.8 as part of intensive resuscitative measures may improve mortality Endoscopic treatment may be safely performed in patients with an INR of <2.5“In patients on anticoagulants, correction of coagulopathy is recommended but should not delay endoscopy” Barkun DDW 2009, Wolf AJG 2007, Baradarian AJG 2004, Choudari Gut, 1994
  • The benefits of early endoscopy Early endoscopy (first 24 hours) allows for  safe and prompt discharge of patients classified as low risk  improves patient outcomes for patients classified as high risk  reduces resource utilization for patients classified as either low or high risk Recent observational data suggest early endoscopy decreases the need for surgery and may improve mortality In a recent UK audit of 208 hospitals (6750 patients), after hours endoscopy just failed to be associated with a drop in mortality Barkun 2003, Ananthakrishnan CGH 2009, Cooper 2009, Hearnshaw 2010
  • Optimal timing of Endoscopy

  • ROLE OF PRIMARY PHYSICIAN SEVERE HAEMETEMESIS RUSH TO HOSPITAL INJECTION TERLIPRESSIN 2mg IV STAT INJECTION OF PPI AND VIT K DO NOT IGNOR EVEN MINOR BLEEDING IT COULD BE A WARNING OF A CATASTROPHY PLEASE KEEP NBM IV FLUIDS AT BRISK RATE
  • VARICEAL BLEED TIMING OF ENDOSCOPIC INTERVENTION WITHIN 24 HOURS OF ADMISSION STABILISE, INVESTIGATE ,TRANSFUSIONS CORRECT COAGULOPATHY, AIRWAY PROTECTION, INITIAL PHARMACOTHEARPY VERY URGENT ENDOSCOPY ONLY IF VERY UNSTABLE PATIENT & VERY PROFUSE BLEED.

  • Conclusion  ABC’s and appropriate resuscitation critical  Early risk stratification, including early endoscopy  Early discharge for very low-risk patients  Endoscopic hemostasis for high-risk lesions  High dose IV PPI are an adjuvant to endoscopic hemostasis  Secondary prophylaxis needed for patients  H pylori  NSAIDs / COX2  ASA /clopidogrel
  • • Clopidogrel alone, aspirin alone, and their combination are all associated with increased risk of GI bleeding• Patients with prior GI bleeding are at highest risk for recurrent bleeding on antiplatelet therapy• PPIs are appropriate in patients with multiple risk factors for GI bleeding who require antiplatelet therapy• Observational studies and a single randomized clinical trial (RCT) have shown inconsistent effects on CV outcomes of concomitant use of thienopyridines and PPIs J. Am. Coll. Cardiol. 2010;56;2051-2066
  • PUB bleeder on ASA – acute management ASA non-adherence/withdrawal carries a 3x risk of major adverse cardiac events The delay to the thrombotic event is usually 7-10 days Immediate reintroduction of ASA is associated with  a statistically non significant increase in recurrent PUD bleeding, BUT  ASA discontinuation causes significantly increased CV mortality* Biondi-Zoccai GG, Eur Heart J, 2006; ; Aguejouf O. Clin Appl Thromb Hemost. 2008 ; Sibon I, Neurology. 2004. Burger W, J Intern Med. 2005; Sung J, Gut (abstract) 2007; Ng, APT, 2004; Sung AIM, 2010, barkun AIM 2010
  • Management of patients who have bled on ASA
  • PUD bleeders who need an NSAID If past PUD bleed, treatment with a traditional NSAID plus PPI or a COX-2 inhibitor alone is still associated with a clinically important risk of recurrent ulcer bleeding Lanza Am J Gastro, 2009; Rostom, APT, 2009.
  • Management of patient who is on NSAIDs
