DEFINITION CAUSES EVALUATION TREATMENT PLAN OF THE TALK
DEFINITION CAUSES EVALUATION TREATMENT PLAN OF THE TALK MEDICAL ENDOSCOPIC SURGICAL
DEFINITION Any bleeding from The gastrointestinal Tract above the Level of ligament of Treitz is upper GI Bleeding
DEFINITIONS Acute GI bleed – < 3 days duration – hemodynamic instability – requires blood transfusion Overt vs. occult – overt = visible blood (melena, bright red blood, coffee grounds) – occult = only detected by lab tests
COMMON CAUSES OF UGI BLEED CAUSE % Peptic Ulcer38% Varix16% Tumor7% MW Tear4% Erosions4% Esophagitis13%
NSAID (1) the risk of gastric ulceration is increased to a greater extent than that of duodenal ulceration (2) the risk of bleeding varies with the individual NSAID; for example, the relative risk of bleeding is greatest with piroxicam and less with ibuprofen (3) the risk of bleeding is dose dependent -age greater than 75 years, -history of heart disease, -history of peptic ulcer - history of previous gastrointestinal bleeding RISK FACTORS
AIRWAY BREATHING CIRCULATION
Not to miss…….. Haemodynamic stability Signs of coagulation dysfunction Signs of Liver cell failure PR
As he comes…………. Resuscitate and Examine Simultaneously…….
Form a team………. Wide bore IV line…… preferably central line (take samples at the same time) Naso gastric tube Urinary Catheter ALERT OTHERS IN TEAM…….
Blood Group Haemogram including platelets Coagulation profile Liver function test Renal function Markers
Blood Sample TRY NOT TO TAKE SAMPLES FREQUENTLY Except for serial evaluation
WHICH TUBE AND WHY?
Naso Gastric Tube or Senstaken tube?
ROLE OF NASOGASTRIC TUBE 10 % of UGIB presents as LGIB Red blood vs coffee grounds NGT clears the gastric field for endoscopic visualization prevent aspiration of gastric content
Endoscopy When to do? What is Possible? When not to do???
Endoscopy One stop Shop Diagnose Assess Treat Reassess
ENDOSCOPIC EVALUATION If Hemodynamically stable Identify Bleeding site Delineate cause Allow endotherapy
ENDOSCOPIC MANAGEMENT VARICEAL NONVARICEAL
ENDOSCOPIC VARICEAL LIGATION A rubber band is placed over the varix which then undergoes thrombosis,sloughing,fibrosis.
Endoscopic Management Bleeding Peptic Ulcer - Stigmata 1a – Spurting vessel 1b – Oozing from a vessel 2 – Clot in the ulcer base 3 – Ulcer without bleed Forrest Classification
SECOND LOOK ENDOSCOPY It is repeat endoscopy 24 hours after initial Endoscopic hemostasis INDICATIONS 1 Incomplete first endoscopic examination due to blood obscuring the field 2 Patients with clinically significant rebleeding
WHEN TO CALL IT AS FAILED ENDOTHERAPY? WHEN TO CALL IT AS FAILED ENDOTHERAPY?
SURGICAL MANAGEMENT OF UGI BLEEDING The Need Only in Select Situations
Role of Surgery 5-10% of UGI Bleed Mortality 3% to 14%
TV Vs H.PYLORI Eradication 40% to 70% of patients with a bleeding duodenal ulcers- positive for H. pylori
Bleeding Gastric Ulcer Simple excision alone -rebleed in 20% of patients 10% incidence of malignancy
Surgical options- Variceal bleeding Shunt Or Devascularisation
Less Common Causes of UGIB
MALLORY WEISS TEARS Managed with 1 Hemoclips 2 MPEC Probes 3 PPI
Mallory-Weiss Tears Angiographic embolization – in cases of failed endoscopic therapy High gastrotomy and suturing of the mucosal tear – failure of all methodes
DIEULAFOY’S LESION large submucosal artery that protrudes through mucosa at the gastric fundus. bleeding can be massive Endoscopic Doppler USG can help localize Endoscopic hemostasis -injection therapy, Thermal probe, clips.
DIEULAFOY'S LESION Failed endoscopic therapy - angiographic coil embolization Surgical intervention - prior endoscopic tattooing – Gastrotomy - bleeding source can be oversewn – Partial gastrectomy - the bleeding point not identified
GASTRIC ANTRAL VASCULAR ECTASIA-GAVE rows of ectatic mucosalVessels(WATERMELON STOMACH) most patients present with persistent, iron deficiency anemia from continued occult blood loss. It is managed with 1 APC-argon Plasma coagulation 2 MPEC Multiple sessions may be needed to eradicate the lesions.
PPPRE APC PPPOST APC
Gastric Antral Vascular Ectasia Endoscopic therapy - successful in up to 90% of patients Failure of endoscopic therapy - antrectomy
SEVERE PORTAL HYPERTENSIVE GASTROPATHY May present with acute or chronic bleed. No role for endoscopic management. Managed with B Blockers, TIPS, Surgical Porto Caval shunt, Liver transplantation.
HEMOBILIA The diagnosis can be confirmed By Side viewing Scopy Ongoing or Recurrent bleed is Treated with angioembolization CAUSES-HEMOBILIA Liver trauma Liver biopsy ERCP/PTC/TIPS HCC, CHOLANGIOCARCINOMA Biliary parasite infestations
HEMOSUCCUS PANCREATICUS The diagnosis can be made by Side viewing scopy Management is by angioembolization CAUSES-HEMOSUCCUS PANCREATICUS Acute pancreatitis/chronic pancreatitis Pancreatic pseudocyst Pancreatic cancer ERCP manipulation of PD Rupture of splenic artery pseudoaneurysm into PD
STRESS GASTRITIS Surgery - rarely indicated Vagotomy and pyloroplasty, with oversewing of the hemorrhage, or near-total gastrectomy - mortality rates as high as 60%
Malignancy Endoscopic therapy - successful in controlling hemorrhage, the rebleeding rate is high Standard cancer operations - indicated when possible Palliative wedge resections – to control bleed
Aortoenteric Fistula Ligation of the aorta proximal to the graft Removal of the infected prosthesis Extra-anatomic bypass Defect in the duodenum - small and can be repaired primarily Typically, patients with bleeding from an aortoenteric fistula will present first with a “sentinel bleed.”
MORTALITY 7% to 10%. The mortality has decreased only minimally during the last 30 years, despite the introduction of endoscopic therapy that reduces the rate of rebleeding. – increasing percentage of UGIB occurring in the elderly – frequent use of antiplatelet medications or anticoagulants – frequent comorbid conditions.
