GI Flashcards
Features and management of biliary colic
Colicky abdo pain, worst post prandially (esp after fatty foods) If imaging shows gallstones, the NBM, analgesia, laparoscopic cholecystectomy
What is courvoisiers law?
- …a patient with a painless, enlarged gallbladder and mild jaundice the cause is unlikely to be gallstones.
- It is more likely to be a malignancy of the pancreas or biliary tree.
Mesenteric ischaemia definition, risk factors and features
Arterial embolism resulting in colon infarction. Most commonly in areas like splenic flexure RF: Age AF Endocarditis CVD RF (e.g. Smoking, htn, diabetes Features… Abdo pain, rectal bleeding, diarrhoea, fever Elevated WBC and acidosis
Bacteria that predisposes to gastritis
H pylori, gram negative urease secreting bacteria In %50 of people in developed countries
Behçet’s syndrome
Thought to be autoimmune… Most often found in Turkish, and men ~20-40 Classically oral / genital ulcers and anterior uveitis Can also get diarrhoea/abdo pain, thrombophlebitis, erythema nodosum, arthritis
Mouth ulcer diagnosis causes and maanagement
Aphthous ulcer. Very common normally Could be Crohn’s, coeliac, Behçet’s, trauma, lichen planus, phemphigoid, pemphigus, herpes, syphilis, Avoid hard abrasive acidic foods Hydrocortisone lozenge Chlorhexidine BIOPSY IF NOT HEALED IN THREE WEEKS
Pt PC lightheaded and lethargic, only treated with naproxen for arthritis. Bloods show MCV 77fL and Hb 73. What investigation next and why?
Do gastroscopy. Patient has iron deficient anaemia, probably from GU and bleed from naproxen (NSAIDs inhibit COX1 and 2, so inhibit prostaglandins… Do increase in gastric acid production and decrease in gastric mucous production. Predisposing to ulcers and bleeds)
Alcoholic comes to ward and started on Chlordiazepoxide and Pabrinex. What are these drugs????
Chlodiazepoxide is a benzodiazepine used for alcohol drug withdrawal Pabrinex is a yellow coloured fluid containing vit B and C. B1 (thiamine) is to prevent Wernicke’s
Definition of severe UC and management
Severe is defined by the Truelove and Witt’s index…. ‘Severe’ if more than 6 stools per day OR blood in stool and one of… ➡️temp above 37.8 ➡️HR above 90 ➡️anaemia (Hb less than 105) ➡️ESR greater than 30mm/️Hr ADMIT TO HOSP AS EMERGENCY IV corticosteroids to induce remission
Risk factors (4) and management of oral candida
Extremes of age DM Immunosuppression Abx Management➡️ is Nystatin or amphotericin (antifungals)
Causes of cheilitis
AKA Angular stomatitis Denture problems Candidiasis Iron or B2 (riboflavin) deficiency
Peutz jeghers syndrome
Auto Dom condition with numerous hamartomatous polyps in GI tract. 59% die by 60 from gi cancer Pigmentation found on lips, face, palms, soles, May present with GI bleeding or intussusception
Diagnosis of infectious mononucleosis
Do a monospot / Paul bunnell test (heterophil antibodies develop in 90%) Atypical lymphocytes too
Old male Pt with dysphagia. Also suffers from regurge and aspiration
Pharyngeal pouch. This is a posteromedial diverticulum through Killians dehiscence - triangle between wall of pharynx, thyropharyngeus and cricopharyngeus muscles 5X more common in men Dysphagia, regurge, aspiration, chronic cough, neck swelling that gurgles on palpation occasionally halitosis Do endoscopic stapling, diverticulotomy, or diverticulotomy
Risk factors for oesophageal cancer
GORD, Male, smoking, drinking, barretts oesophagus, achalasia (if untreated)
Description and management of Achalasia
➡️Lower oesophageal sphincter fails to relax ➡️Unknown cause but probably due to degeneration of myenteric plexus ➡️Dilated tapering on barium swallow Mx ➡️Endoscopic balloon dilation ➡️Then PPI ➡️Can give CCB ➡️Botulinum can help relax
Causes of dysphagia (organise into categories)
Basically urgent refer all ➡ Mechanical block …malignant (oesoph, gastric, pharyngeal) …benign (oesoph web, peptic stricture) …extrinsic (lung ca, mediastinal LN, goitre, AA) …pharyngeal pouch ➡️ Motility disorder (Achalasia, MG, systemic sclerosis) ➡️ Other …oesophagitis –>infection: candida, HSV; reflux disorder …globus hystericus
Types of hiatus hernia
Sliding (80%) and rolling. ➡️Sliding is where the gastro-oesophageal junction slides up into chest - reflux is common ➡️Rolling is where the GOJ is still in abdomen but a bulge of stomach rolls up - reflux is uncommon
Red flag symptoms with dyspepsia And referral
️Anaemia Loss of weight Anorexia Recent onset of progressive symp Melaena or haematemesis Swallowing difficulties Urgent investigation if weight loss Non urgent ix if over 55 with ⬆️️platelets/N/V and dyspepsia
Referral for oesoph and stomach cancer
Urgent referral for patients ….with dysphagia ….with upper abdo mass(?stomach ca) ….over 55 with weight loss AND upper abdo pain, reflux, dyspepsia Non urgent ….with haematemesis Or over 55 with… ….treatment-resistant dyspepsia ….upper abdo pain with low Hb ….raised platelet count and n/v/weight loss/reflux/dyspepsia/upper abdo pain ….n or v with weight loss/reflux/dyspepsia/upper abdo pain
When is pain classically worse with gallstones, and why??
Pain is classically colicky RUQ, post prandially. Especially after fatty meals, when CHOLECYSTOKININ levels are highest and gallbladder contraction is maximal.
Patient with fatigue, RUQ pain, jaundice and itchiness and Hx of ulcerative colitis
Primary sclerosing cholangitis 4% of UC patients have PSC 80% of PSC patients have UC unknown aetiology, inflam and fibrosis of ️intra and extra hepatic bile ducts ERCP to diagnose, with ‘beaded’ appearance ANCA may be positive Cholangiocarcinoma is a complication in 10% + risk of CRC
Pt with dyspepsia management
If over 55 or ALARM Symps then endo If none ➡️ stop any drugs ……..mucosa damage:NSAIDs, bisphosphonates ……..oesoph motility:TCA, antichol, ……..CCB relax LOS ➡️ lifestyle changes ……..weight loss, smoking cessation, raise head of bed avoid hot drinks, avoid citric, avoid spice, tomatoes onions ➡️ OTC antacids ➡️ review in 4wk …if not improved do carbon13 urea breath test or stool antigen test for H pylori
Which is more common, DU or GU?
DU is four times more common DU pain often occurs several hours after eating
